Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a double harvester for composite planting of soybeans and corns. Background Art

[0002] When planting corn and soybeans in strips, most of the pilot tests now use two rows of corn and two to four rows of beans, so it is called strip planting. It can avoid blocking light, meet the needs of both crops, and produce the highest yield in the smallest area to the greatest extent.

[0003] When the corn and soybean strips are planted together, they need to be harvested by a harvester. Existing soybean and corn harvesters can usually only harvest one crop. In the soybean and corn field, harvesting can only be done in batches. When harvesting, it is inevitable that the crops next to it will be affected, resulting in a reduction in field yield. Therefore, the above-mentioned soybean and corn harvesters cannot perform compound double harvesting, resulting in a reduction in yield, which urgently needs to be solved to increase crop yields.

[0004] After searching, the double harvester for composite planting of soybean and corn disclosed in patent publication number CN219395573U can solve the problems existing in the prior art when used, but it still has certain disadvantages in actual use. When cleaning the lighter straw in the storage bin, the fan blows air into the storage bin through the air duct, blowing the lighter straw inside outward, and blows it to both sides under the action of the wind hood, but some of the lighter straw will be pressed at the bottom of the crops, and the blowing area of only one air duct is small, and the air flow direction is blowing towards the crops, which makes it difficult to blow out the straw, resulting in incomplete cleaning of the lighter straw and poor straw cleaning effect in the storage bin. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a double harvester for soybean and corn composite planting, which can make straw cleaning more thorough and improve the cleaning effect of straw in a storage bin.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: when in use, after the soybeans and corn are harvested, they are sent to different storage bins for storage through conveyor belts. During the storage process, the fan and the turning motor are started. By starting the fan, the fan blows air into the blower box through the blower pipe, and the air flow blows evenly from the side to the crops that fall into the storage bin through the blowing holes on the flow equalizing plate, so that the lighter straw in the crops is blown to the outside under the action of the wind hood, and by starting the turning motor, the turning motor drives the stirring rod to rotate, so that the stirring rod drives the turning blades to turn the crops at the bottom, and the straw pressed at the bottom is turned to the top by turning, and the lighter straw is blown to the outside under the uniform blowing of the air flow, thereby ensuring the cleanliness of the storage bin, making the straw cleaning more thorough, and improving the cleaning effect of the straw in the storage bin.
