[0030] This utility model provides, for example Figure 1 - Figure 5The illustrated device integrates bean threshing and air separation, comprising a bean threshing machine body 1. A load-bearing plate 2 is fixedly installed on one side of the bean threshing machine body 1 near the bottom. An induced draft fan body 3 is fixedly installed at the top center of the load-bearing plate 2. A connecting pipe 4 is inserted into the other side of the induced draft fan body 3. A through-hole is opened on one side of the bean threshing machine body 1 near the center, and the other end of the connecting pipe 4 passes through the inner cavity of the through-hole and is fixedly installed with a nozzle 6. (By setting the induced draft fan body 3 and the nozzle 6, air can be blown into the screening plate 7, which can air separate the beans on the screening plate 7.) The bottom of the nozzle 6 is fixedly connected to the bottom of the inner cavity of the bean threshing machine body 1. A flow guide box 10 is fixedly installed on the other side of the bean thresher body 1. (A U-shaped plate is fixedly installed on the front side of the flow guide box 10 to facilitate the subsequent flow of beans.) A flow guide plate 5 is fixedly installed on the opposite side of the inner cavity of the flow guide box 10. A striking component 9 is provided at the bottom of the flow guide plate 5. A screening plate 7 is fixedly installed on one side of the inner cavity of the bean thresher body 1 near the top. Several discharge holes are opened on the top of the screening plate 7. Several discharge holes are evenly distributed on the screening plate 7. An opening is opened on the other side of the bean thresher body 1 near the middle position. The other side of the screening plate 7 penetrates the inner cavity of the opening and extends to the outside of the bean thresher body 1. A dispersing component 8 is provided on the top of the screening plate 7 near the other side.

[0031] Specifically, the dispersing component 8 includes an L-shaped frame 81 fixedly installed on the front and rear sides of the main body 1 of the bean thresher near the other side, and a support plate 82 fixedly installed on the rear L-shaped frame 81. A drive motor 83 is fixedly installed on the top of the support plate 82. A reciprocating screw 84 is fixedly installed on the end of the power output shaft of the drive motor 83. The front end of the reciprocating screw 84 moves through the adjacent L-shaped frame 81 and is rotatably connected to the L-shaped frame 81 away from it. A screw nut 85 is movably sleeved on the outer periphery of the reciprocating screw 84 near the rear end. A connecting plate 86 is fixedly installed on the bottom of the screw nut 85. Several actuating rods 87 are provided on the bottom of the connecting plate 86.

[0032] Advantageously, by setting the dispersion component 8, when the reciprocating screw 84 rotates, the screw nut 85 movable on the reciprocating screw 84 can move back and forth under the limitation of the limiting block 851 and the limiting rod 852. With the connection of the reset telescopic rod 871 and the reset spring 872, the adjacent toggle rod 87 can move back and forth, thereby preventing the threshed beans from accumulating on the top of the screening plate 7 and improving the efficiency of bean air separation.

[0033] Specifically, a limiting block 851 is fixedly installed on the top of the lead screw nut 85, and the front side of the limiting block 851 moves through the limiting rod 852, and the front and rear ends of the limiting rod 852 are respectively fixedly connected to the adjacent L-shaped frame 81.

[0034] It is advantageous that by setting the limit block 851 and the limit rod 852, the movement of the lead screw nut 85 can be limited, thereby improving the stability of its movement.

[0035] Specifically, a reset telescopic rod 871 is fixedly installed on the top of each toggle lever 87, and the top of each reset telescopic rod 871 is fixedly connected to the connecting plate 86. A reset spring 872 is movably sleeved on the outer periphery of each reset telescopic rod 871, and the two ends of the reset spring 872 are fixedly connected to the connecting plate 86 and the toggle lever 87, respectively.

[0036] It is advantageous that by setting the reset telescopic rod 871 and the reset spring 872, the toggle rod 87 can be tightly in contact with the screening plate 7, thereby improving the subsequent dispersion effect on beans.

[0037] Specifically, the striking assembly 9 includes a straight rod 91 rotatably connected to the front side of the inner cavity of the flow guide box 10 near the bottom and several eccentric wheels 92 fixedly sleeved on the outer periphery of the straight rod 91. The rear end of the straight rod 91 moves through the inner cavity side wall of the flow guide box 10. The top of each eccentric wheel 92 is provided with a T-shaped rod 93. A rectangular plate 94 is fixedly installed on opposite sides of the inner cavity of the flow guide box 10. The top of each T-shaped rod 93 moves through the top of the rectangular plate 94 and is fixedly installed with a rubber block 95.

[0038] With the help of the striking component 9, when the straight rod 91 rotates, several rubber blocks 95 can continuously strike the guide plate 5, thereby preventing the beans after air separation from accumulating on the guide plate 5 and speeding up the efficiency of bean feeding.

[0039] Specifically, a compression telescopic rod 951 is fixedly installed on the bottom of the rubber block 95 near both sides, and the bottom end of the compression telescopic rod 951 is fixedly connected to the rectangular plate 94. A compression spring 952 is movably sleeved on the outer periphery of the compression telescopic rod 951, and the top and bottom ends of the compression spring 952 are fixedly connected to the rubber block 95 and the rectangular plate 94, respectively.

[0040] It is advantageous that by setting the compression telescopic rod 951 and the compression spring 952, the T-shaped rod 93 can be restored to its initial state when the eccentric wheel 92 is not in contact with the T-shaped rod 93.

[0041] Specifically, a timing pulley 911 is fixedly sleeved on the outer periphery of both the straight rod 91 and the reciprocating lead screw 84 near the rear end, and a timing belt 912 is sleeved on both timing pulleys 911.

[0042] It is advantageous that by setting the synchronous pulley 911 and the synchronous belt 912, the straight rod 91 can rotate synchronously when the reciprocating screw 84 rotates.

[0043] Working Principle: In use, the operator places the bean plants into the threshing chamber. Under the action of the main body 1 of the bean threshing machine, the pods, seeds, and chopped straw are crushed and fall onto the top of the screening plate 7, then slide to the other side. Afterwards, the drive motor 83 and the load-bearing plate 2 can be started via an external controller. The rotation of the drive motor 83's power output shaft drives the reciprocating screw 84 fixed to the end of the drive motor 83's power output shaft to rotate. This causes the screw nut 85, which moves around the outer periphery of the reciprocating screw 84, to move back and forth under the limitation of the limit block 851 and the limit rod 852. The movement is controlled by the connecting plate 86 fixed to the screw nut 85, the reset telescopic rod 871, and the reset... The spring 872 enables the actuating rod 87 to move, turning over the accumulated impurities and grains. With the activation of the load-bearing plate 2, the threshed beans can be air-separated. The air-separated beans pass through the discharge hole and fall on the top of the guide plate 5. Under the transmission of the synchronous pulley 911 and the synchronous belt 912, the straight rod 91 can be rotated. Through the eccentric wheel 92 fixed on the straight rod 91, several T-shaped rods 93 can move up and down reciprocally under the cooperation of several compression telescopic rods 951 and compression springs 952. This allows several rubber blocks 95 to continuously strike the guide plate 5, thereby preventing the air-separated beans from accumulating on the guide plate 5 and speeding up the efficiency of bean discharge.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
