Grain Hopper Trailer
A grain hopper trailer is a trailer pulled by a semi tractor and used to haul bulk commodity products, such as grain. These trailers are used extensively throughout the United States to transport agricultural products as well as any other commodity that can be hauled in bulk and loaded and unloaded through the trailer. Design Grain hopper or hopper-bottom trailers typically feature a rolling tarp on the top of the trailer, to enable easy loading of the product to be transported, and also offer protection during transport. They utilize two hoppers on the base of the trailer to unload to product, one servicing the rear half of the trailer, the other the front half. The output of these hoppers is usually controlled by a sliding plate on the base of the hopper, controlled by a user-operated crank handle. Usage A grain hopper trailer is used in conjunction with various other pieces of agricultural machinery to complete the harvest of a field. Combine harvesters or similar unload ...

Grain Carts
A grain is a small, hard, dry fruit (caryopsis) – with or without an attached husk, hull layer – harvested for human or animal consumption. A grain crop is a grain-producing plant. The two main types of commercial grain crops are cereals and legumes. After being harvested, dry grains are more durable than other staple foods, such as starchy fruits (plantain (cooking), plantains, breadfruit, etc.) and tubers (sweet potatoes, cassava, and more). This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported by rail or ship, stored for long periods in silos, and mill (grinding), milled for flour or expeller pressing, pressed for Seed oil, oil. Thus, the grain market is a major global commodity market that includes crops such as maize, rice, soybeans, wheat and other grains. Cereal and non-cereal grains In the grass family, a grain (narrowly defined) is a caryopsis, a fruit with its wall fused on to the single seed ...

Hopper Car
A hopper car () or hopper wagon () is a type of railroad freight car that has opening doors or gates on the underside or on the sides to discharge its cargo. They are used to transport loose solid bulk commodities such as coal, ore, grain, and track ballast. Plastic pellets and some finely ground material, similar to flour, are transported in hopper cars that have pneumatic unloading. The bottom gates on the pneumatic hoppers connect to a hose attached to industrial facilities' storage tanks. Air is injected to fluidize the railcar contents for unloading. The hopper car was developed in parallel with the development of automated handling of such commodities, including automated loading and unloading facilities. Hopper cars are distinguished from gondola cars, which do not have opening doors on their underside or sides. Gondola cars are simpler and more compact because sloping ends are not required, but a rotary car dumper is required to unload them. Some "dual-purpose" ...

Gravity Wagon
The gravity wagon, or slant wagon, is an angled hopper style wagon that utilizes gravity to make the unloading process easier. It is primarily used on farms for agricultural purposes, such as for holding crops or fertilizer. For easy comparison, it is similar to a railroad hopper car, only with one door which is located on the bottom side rather than on the bottom center. Description A gravity wagon has three sides which are angled at about 45 degrees and one side that is vertical. An unloading door is located at the bottom of the vertical side where the three angled sides come together. This design causes the contents of the wagon to funnel towards the door so that no effort has to be put forth to unload the contents other than opening the door, which opens upwards by the action of a lever or turning of a wheel. The chassis used for gravity wagons is sometimes the same as the chassis used for hay wagons. See also * Forage wagon * Grain hopper trailer * Combine harveste ...

Grain Bin
Grain bins are bulk storage structures for dry wheat, soybean, maize, oats, barley and more. Grain bins are cylinders made of corrugated sheets or sheet metal with a coned metal roof that has vents. The floors of grain bins have aeration systems to keep good air flow through the stored products and keep it at a good temperature and humidity level to prevent spoilage. In smaller grain systems, bins may serve both drying and storage purposes when a dedicated grain dryer is not present. These drying bins often use a stirring machine to mix dried grain at the bottom with wetter grain near the top, promoting even moisture levels throughout the bin. In drying bins, heated air is pushed through the grain using fans, with attached heaters, located at the base of the bin. Grain bins may be filled using augers in smaller setups, while larger systems typically use receiving pits for unloading grain from hopper trailers. From the pit, grain is raised vertically using a bucket elevator ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Grain Elevator
A grain elevator or grain terminal is a facility designed to stockpile or store grain. In the grain trade, the term "grain elevator" also describes a tower containing a bucket elevator or a pneumatic conveyor, which scoops up grain from a lower level and deposits it in a silo or other storage facility. In most cases, the term "grain elevator" also describes the entire elevator complex, including receiving and testing offices, weighbridges, and storage facilities. It may also mean organizations that operate or control several individual elevators, in different locations. In Australia, the term describes only the lifting mechanism. Before the advent of the grain elevator, grain was usually handled in bags rather than in bulk (large quantities of loose grain). The Dart elevator was a major innovation—it was invented by Joseph Dart, a merchant, and Robert Dunbar, an engineer, in 1842, in Buffalo, New York. Using the steam-powered flour mills of Oliver Evans as their model, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Silo
A silo () is a structure for storing Bulk material handling, bulk materials. Silos are commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. Three types of silos are in widespread use today: tower silos, bunker silos, and bag silos. Silos are used in agriculture to store fermented feed known as silage. Types of silos Tower silo Storage silos are cylindrical structures, typically 10 to 90 ft (3 to 27 m) in diameter and 30 to 275 ft (10 to 90 m) in height with the Slip forming, slipform and Jumpform concrete silos being the larger diameter and taller silos. They can be made of many materials. Wood staves, concrete staves, cast concrete, and steel panels have all been used, and have varying cost, durability, and airtightness tradeoffs. Silos storing grain, cement and woodchips are typically unloaded with air slides or augers. Silos can be unloaded into rail cars, trucks or conveyors. Tower silos conta ...

Screw Conveyor
A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw (simple machine), screw blade, called a "''flighting''", usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, Woodchips, wood chips, aggregates, cereal, cereal grains, animal feed, boiler ash, meat, bone meal, municipal solid waste, and many others. The first type of screw conveyor was the Archimedes' screw, used since ancient times to pump irrigation water. They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a "''shaftless spiral''", driven at one end and free at the other. The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications, the de ...

Combine Harvester
The modern combine harvester, also called a combine, is a machine designed to harvest a variety of cultivated seeds. Combine harvesters are one of the most economically important labour-saving inventions, significantly reducing the fraction of the population engaged in agriculture. Among the crops harvested with a combine are wheat, rice, oats, rye, barley, Maize, corn (maize), sorghum, millet, soybeans, flax (linseed), sunflowers and rapeseed (canola). The separated straw (consisting of stems and any remaining leaves with limited nutrients left in it) is then either chopped onto the field and ploughed back in, or laid out in rows, ready to be Baler, baled and used for bedding and cattle feed. The name of the machine is derived from the fact that the harvester combined multiple separate harvesting operations – Reaper, reaping, threshing or winnowing and gathering – into a single process around the start of the 20th century. A combine harvester still performs its functions ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Tractor Unit
A tractor unit, also known as a truck unit, lorry unit, power unit, prime mover, ten-wheeler, semi-tractor, semi-truck, semi-lorry, tractor cab, truck cab, lorry cab, big rig tractor, big rig truck or big rig lorry or simply a tractor, truck, lorry, semi, big rig or rig, is a characteristically heavy-duty towing engine that provides motive power for hauling a towed or trailered load. The largest such vehicles are similar to locomotives. These fall into two categories: heavy- and medium-duty military and commercial rear-wheel-drive semi-tractors used for hauling semi-trailers, and very heavy-duty typically off-road-capable, often 6×6, military and commercial tractor units, including ballast tractors. It should not be confused with a tractor-trailer which is a combination of a tractor unit and semi-trailer, whereas a ''tractor unit'' describes only the tractor portion.

Harvest
Harvesting is the process of collecting plants, animals, or fish (as well as fungi) as food, especially the process of gathering mature crops, and "the harvest" also refers to the collected crops. Reaping is the cutting of grain or pulses for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season. On large mechanized farms, harvesting uses farm machinery, such as the combine harvester. Automation has increased the efficiency of both the seeding and harvesting processes. Specialized harvesting equipment, using conveyor belts for gentle gripping and mass transport, replaces the manual task of removing each seedling by hand. The term "harvesting" in general usage may include immediate postharvest handling, including cleaning, sorting, packing, and cooling. The completion of harvesting marks the end of the growing season, or the growing cycle for a particular c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
