[0002] Edamame, peas and other legumes are common green foods on the Chinese table. They are delicious, nutritious and have a huge market demand. Although the traditional manual shelling method can produce high-quality bean kernels, it is time-consuming, labor-intensive, inefficient, unhygienic and costly, bringing various inconveniences to producers. Various bean shelling machines are now used to shell beans. In the process of shelling beans by the bean shelling machine roller, a bean shelling machine is disclosed in the patent with application number 202122347181.3, wherein the hopper includes an upper hopper and a lower hopper, and the side of the upper hopper is connected to the side of the lower hopper by a hinge; an inclined feeding partition is arranged in the opening of the upper hopper; an inclined guide plate is arranged on one side of the lower hopper below the feeding partition. When feeding, the edamame pods are put into the open hopper and enter the interior of the hopper through the feeding partition on the upper part of the hopper. However, the feeding partition cannot control the feeding of the beans, so that too many beans on the feeding plate will affect the feeding effect of the comb teeth on the beans, and even cause the beans to be stuck between the hopper and the feeding plate, affecting the normal use of the feeding plate.

[0021] The bean peeling mechanism comprises a guide roller group 10 connected to the end of the guide groove 9 of the guide plate 8, and a knurled shaft group 11 is provided on one side of the guide roller group 10.

[0022] The knurled shaft assembly 11 comprises a lower knurled shaft 12 and an upper knurled shaft 13 movable relative to the lower knurled shaft 12 . A limit block 14 is disposed on one side of the upper knurled shaft 13 . An electric push rod 15 is disposed on the upper side of the limit block 14 to drive the limit block 14 to move.

[0023] The screening mechanism includes a sieve plate 16 arranged at the lower side of the knurled shaft group 11. The sieve plate 16 is an inclined sieve plate with evenly distributed sieve holes 17. A first material receiving barrel 19 is arranged at the lower side of the sieve plate 16, and a second material receiving barrel 29 is arranged at the discharge end of the sieve plate 16.

[0024] A weighing platform 28 is disposed under the first material receiving barrel 19 and the second material receiving barrel 29 .

[0025] The frame 1 is provided with a pulley motor 30, a first pulley 31 is provided on one side of the pulley motor 30, a first transmission belt 32 is provided on the first pulley 31, a second pulley 33 corresponding to the first transmission belt 32 is provided at the end of the lower knurled shaft 12, a third pulley 34 coaxially arranged with the second pulley 33 is provided on one side of the second pulley 33, a second transmission belt 35 is provided on the third pulley 34, a fourth pulley 36 corresponding to the second transmission belt 35 is provided in the guide roller group 10, a fifth pulley 37 coaxially arranged with the fourth pulley 36 is provided on one side of the fourth pulley 36, a third transmission belt 38 is provided on the fifth pulley 37, and a sixth pulley 39 corresponding to the third transmission belt 38 is provided at the end of the rotating shaft 6.

[0026] The principle of the utility model is as follows: the unshelled beans are stored in the hopper 2. When working, the linear reciprocating motor 5 can drive the movable baffle 4 to make reciprocating motion, so that the fixed baffle 3 and the movable baffle 4 will be opened or closed at a fixed time, so that the beans can fall onto the guide plate 8 in an orderly manner, and the push plate 7 is driven by the rotating shaft 6 so that the beans can be consistent with the direction of the guide groove 9. Under the action of the vibration motor 18, the beans can slide along the guide groove and enter the bean peeling mechanism. When the linear reciprocating motor 5 is working, the push rod motor drives the rotating rod 24 to rotate. The rotating rod 24 and the connecting rod 25 are connected by a fixed shaft, and the two can move relative to each other. During the rotation of the rotating rod 24, the distance from the end of the rotating rod 24 to the limit seat 27 will change, so that the connecting rod 25 drives the push rod 26 to make a linear motion along the limit seat 27, realizing the linear motion of the movable baffle 4. The beans will then move toward the knurled shaft group 11 under the action of the guide roller group 10. If the gap of the knurled shaft group 11 is smaller than the size of the beans, the bean shells will pass through the knurled shaft group 11, and the beans will be squeezed out of the bean shells and fall on the sieve plate 16. In this application, there is only two-level sorting. Small beans will fall from the sieve holes 17, while large beans will roll along the sieve plate 16, fall from the discharge end of the sieve plate 16, and fall into the second receiving barrel 29. Further, a weighing platform 28 is provided under the first receiving barrel 19 and the second receiving barrel 29. The weighing platform 28 adopts a resistive strain type pressure sensor. A control module is also provided on the frame of this application. When the weighing platform 28 detects that the weight of the first receiving barrel 19 and the second receiving barrel 29 reaches a threshold, it will control the operation of the vibration motor 18, the linear reciprocating motor 5 and the pulley motor 30 to prevent too much beans loaded in the first receiving barrel 19 and the second receiving barrel 29 from falling to the ground and causing waste.
