Dumping device of harvester

Abstract

The invention belongs to the technical field of agricultural machines and relates to a dumping device of a harvester. The dumping device of the harvester comprises a rack and a clamping jaw, wherein a clamping disc which is coaxial with a storage hopper rotating shaft is arranged on the rack, clamping teeth are arranged on the periphery of the clamping disc, and clamping grooves are formed between adjacent clamping teeth; the clamping jaw is matched with the clamping grooves, the clamping jaw is welded at the upper part of an obliquely arranged control rod, the upper end of the control rod is hinged with the rack and the lower end of the control rod is connected with the rack through a return spring; the middle part of the control rod is provided with a driven column in contact with a cam. The dumping device of the harvester has the advantages that the structure is simple, the dumping angle of the storage hopper can be more conveniently controlled and grains in the storage hopper can be dumped to a designated position.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery. Background technique [0002] my country's crop production is gradually becoming mechanized, automated and integrated. In the North China Plain, which is an important food area in my country, the main food crops are wheat, rice, corn, sorghum, millet and sweet potatoes, etc. The main economic crops are cotton, peanuts, sesame, soybeans and tobacco etc. Nowadays, the harvesting of many grain crops has been automated. Use harvesters, harvesters or other harvesting machinery to harvest grain. If it is grain with small particles such as wheat, you can open the outlet at the lower part of the harvester's storage bucket. Grain unloading, but large grains such as corn and sweet potatoes cannot use this unloading direction, because it is easy to block the outlet. This kind of grain is usually dumped and unloaded by turning the storage bucket. The dumping angle is not easy to control, usua...

Problems solved by technology

Nowadays, the harvesting of many grain crops has been automated. Use harvesters, harvesters or other harvesting machinery to harvest grain. If it is grain with small particles such as wheat, you can open the outlet at the lower part of the harvester's storage bucket. Grain unloading, but large grains such as corn and sweet potatoes cannot use this unloading direction, because it is easy to block the outlet. This kind of grain is usually dumped and unloaded by turning the storage bucket. The dumping angle is not easy to control, usually in the form of a full tipping bucket. The disadvantage of the full tipping bucket is that it is impossible to accurately pour the grain into the designated position
