Description

Technology Field

[0001] The present invention relates to a soybean discharge device for a soybean harvesting complex, and more specifically, to a soybean discharge device for a soybean harvesting complex that is equipped with a soybean harvesting and threshing machine that harvests soybeans, threshs and sorts the soybeans, and discharges the soybeans to the outside by using a donut-shaped rotary conveyor to move them from the bottom to the top discharge port, thereby preventing damage to the soybeans and ensuring that no residue remains. Background Technology

[0003] Generally, soybeans are obtained by cutting the stalks from the field in the autumn, drying them, and then using a soybean threshing machine or by shaking the stalks by hand. Specifically, when harvesting soybeans, the pods and stalks are struck to detach the beans inside the pods, and the detached beans are then separated from the pods and stalks. Since performing this harvesting manually requires a lot of physical strength, soybean threshing machines are being introduced in various forms to make the harvesting process more efficient.

[0005] A conventional soybean threshing machine comprises a threshing unit consisting of a four-point satellite threshing shaft and a threshing net, a conveying unit consisting of a vibrating sieve that conveys soybeans threshed in the threshing unit and has a sorting function with a perforated net installed at one end, a sorting unit having a suction fan that filters out foreign substances before the soybeans reach the perforated net of the vibrating sieve, a discharge unit consisting of an air-transporting elevator that discharges the soybeans sorted by the vibrating sieve into a bag, and a power unit that provides power to the entire threshing machine. However, since the soybean threshing machine is merely a device that threshs soybean stalks harvested from a field after drying them, there is a problem in that threshing does not occur simultaneously with the harvesting of the soybean stalks.

[0007] Accordingly, a soybean combine has recently been developed that cuts soybean stalks directly in the field, threshes them immediately, and stores them in a grain tank. The soybean combine cuts the soybean stalks through a cutting unit equipped at the front, transports the cut stalks to a threshing unit for threshing, separates and discharges foreign substances such as soybean pods and stalks, and stores the threshed soybeans in a grain tank, thereby eliminating a separate threshing process and improving productivity.

[0009] However, devices for discharging threshed beans include air lifts used in threshers and bucket lifts used in combines. Air lifts have the advantage of causing less damage to grains, such as beans, and achieving a clean sorting effect; however, they suffer from reduced throughput due to performance degradation depending on the airflow volume, intensity, and the foreign matter content of the transported discharge. On the other hand, bucket lifts are the most common method for transporting a fixed amount of grain and have the advantage of being able to transport various types of grain; however, they have the disadvantage of leaving residue at the bottom of the lift and increasing the probability of grain damage. Therefore, it is necessary to minimize grain damage through precise settings.

[0011] Meanwhile, Registered Patent No. 10-2051491 describes a grain threshing machine comprising: a crop input section; a first threshing drum located in front of the crop input section and installed to rotate at a constant speed by power transmission, having a plurality of striking protrusions on its outer surface to strike crops fed through the crop input section for primary threshing processing; and a first threshing net installed below the first threshing drum and discharging the thawed grains, which are primary threshed through the first threshing drum, to a vibrating body located below; wherein the machine comprises: a second threshing drum located in front of the first threshing drum and installed to rotate at a constant speed by power transmission, having a radially arranged structure on its outer surface and threshing blades protruding at regular intervals; A grain threshing machine is disclosed that includes a second threshing screen installed below the second threshing drum, which threshs the crop together with the second threshing drum to remove the residue by striking it in a second threshing process, and can increase the threshing rate of grains such as sesame or perilla that have small particles and are difficult to thresh, and can improve threshing performance.

[0013] In addition, Registered Utility Model No. 20-0344538 comprises a pair of inner plates fixed to a support frame so as to be positioned between two outer plates, a soybean hull discharge guide plate installed to rotate up and down between the inner plates, a guide plate detachably coupled to be positioned between the inner plates above the soybean hull discharge guide plate to form a flow path between the soybean hull discharge guide plates, a soybean discharge plate installed at a downward inclination from the rotation point of the soybean hull discharge guide plate, a sorting soybean guide plate installed at an upward inclination opposite to the soybean discharge plate above the rotation point of the soybean hull discharge guide plate, a hopper fixed to the upper part of a back plate fixed to the back surface of the support frame for holding soybeans containing soybean hulls and foreign substances, an input hole formed in the back plate located at the bottom of the hopper to feed soybeans in the hopper into the soybean guide plate, an impeller axially installed to be positioned between the soybean discharge plate and the soybean guide plate to blow air through the space between them, and the A soybean threshing machine capable of sorting soybeans is proposed and disclosed, comprising a housing installed to surround the outer surface of an impeller and covers installed at openings on both sides of the housing to generate wind within the housing as the impeller rotates, thereby enabling not only threshing but also the automatic filtering of soybean pods and foreign substances contained in the soybeans after threshing is completed, and then the automatic sorting of soybeans by size.

[0015] In addition, Registered Utility Model No. 20-0405070 proposes and discloses a soybean discharge device for a soybean threshing machine, wherein a synthetic resin discharge pipe made of an elastic body is connected to the discharge port of a soybean discharge groove formed in the lower part of the threshing chamber of the threshing machine to form a discharge port on the upper outer side, a support member is attached to the upper part of the synthetic resin discharge pipe to fix it to the outer wall of the threshing machine, an axial member is made on the inner part of the soybean discharge groove and the upper part of the soybean discharge pipe, and a soybean conveyor in the shape of a coil spring is installed from the soybean discharge groove to the soybean discharge pipe, wherein the drive shaft of the soybean conveyor is supported by the axial member on the inner part of the soybean discharge groove and the upper support shaft is supported by the upper shaft support member of the soybean discharge pipe, thereby enabling the drive shaft of the soybean conveyor to be driven.

[0017] In addition, Public Patent No. 10-2014-0137876 proposes and discloses a sorting mechanism for a soybean threshing machine that threshes soybean crops with a drum, discharges by-products, and collects soybeans, comprising: a vibrating part that separates soybeans and by-products by vibrating a vibrating body in the downward direction of the drum; a conveying part installed in the downward direction of the vibrating part and conveying soybeans with a conveying screw; and a collecting part provided to communicate a collection duct on one side of the conveying part and conveying soybeans upward through the collection duct; wherein by-products are not discharged mixed with soybeans, only completely sorted soybeans are finally collected, thereby enabling reduction of labor costs and improvement of productivity by eliminating subsequent operations.
