An adjustment structure 9 is provided on the surface of the frame 1. By setting the adjustment structure 9, it is easy to adjust the tightness of the transmission belt 7 installed on the driving wheel 6 and the transmission wheel 10, thereby improving the rotation effect of the servo motor 5 to drive the screening net 4, thereby improving the effect of sorting walnuts.
[0030] The specific settings and functions of the limiting structure 8 and the adjusting structure 9 are described in detail below.
[0031] Reference Figure 2 and Figure 3 and Figure 4As shown, in this embodiment: the limiting structure 8 includes a bracket 801, the bracket 801 is fixedly connected to the surface of the sorting box 2, the surface of the bracket 801 is rotatably connected with a bidirectional screw 802, the surface of the bidirectional screw 802 is fixedly connected with a turntable 803, the surface of the bidirectional screw 802 is threadedly connected with two driving arms 804, the sides of the two driving arms 804 close to each other are fixedly connected with a limiting plate 805, and the surface of the sorting box 2 is covered with a collection bag 806. The surface of the limiting plate 805 is fixedly connected with a convex strip 807, and the surface of the sorting box 2 is provided with a limiting groove 808, the size of the limiting groove 808 is adapted to the size of the convex strip 807, the movement of the limiting plate 805 will drive the convex strip 807 to move, when the limiting plate 805 squeezes the collection bag 806 on the surface of the sorting box 2, the convex strip 807 squeezes the collection bag 806 into the limiting groove 808, thereby further improving the effect of limiting the collection bag 806. The surface of the sorting box 2 is fixedly connected with a plurality of spikes 809, which are evenly fixedly connected to both sides of the sorting box 2. The spikes 809 pass through the collecting bag 806, and the spikes 809 reach the position of temporarily limiting the collecting bag 806, so as to facilitate the collecting bag 806 to be tightly limited on the surface of the sorting box 2. The surface of the driving arm 804 is slidably penetrated by a round rod 810, and the round rod 810 is fixedly connected to the surface of the bracket 801. When the driving arm 804 moves, it will slide along the surface of the round rod 810, and the round rod 810 reaches the effect of limiting the moving path of the driving arm 804, so as to prevent the driving arm 804 from rotating when moving.
[0032] Reference Figure 5 As shown, specifically, the adjustment structure 9 includes two fixing plates 91, both of which are fixedly connected to the surface of the frame 1, a rectangular rod 92 is slidably penetrated through the surface of the fixing plate 91, a latch 93 is slidably penetrated through the surface of the fixing plate 91, a plurality of circular grooves 94 are provided on the surface of the rectangular rod 92, the size of the circular groove 94 is adapted to the size of the latch 93, and a pressing block 95 is fixedly connected to one end of the rectangular rod 92 close to the transmission belt 7. A groove 96 is provided on the surface of the pressing block 95, and a rotating wheel 97 is rotatably connected to the inner wall of the groove 96. After the rotating shaft moves to a suitable position, it will be pressed on the surface of the transmission belt 7. When the transmission belt 7 rotates, it will drive the rotating shaft to rotate in the groove 96, and the rotating shaft can reduce the friction between the pressing block 95 and the transmission belt 7. The arc surface of the latch 93 is covered with a spring 98, and the two ends of the spring 98 are fixedly connected to the latch 93 and the fixing plate 91 respectively. The latch 93 will be inserted into the circular groove 94 with the help of the contraction force of the spring 98, and the spring 98 can improve the stability of the latch 93 inserted into the circular groove 94.
[0033] Working principle: when it is necessary to limit the collection bag 806 to the sorting box 2, first put the collection bag 806 on the surface of the sorting box 2, so that the spikes 809 pass through the collection bag 806, and the spikes 809 reach the position of temporarily limiting the collection bag 806, so as to facilitate the collection bag 806 to be tightly limited on the surface of the sorting box 2, and then rotate the turntable 803. The rotation of the turntable 803 will drive the bidirectional screw 802 to rotate, and the rotation of the bidirectional screw 802 will rotate in the bracket 801. The rotation of the bidirectional screw 802 will drive the driving arm 804 to move with the help of the thread. The movement of the driving arm 804 will slide along the surface of the round rod 810, and the round rod 810 reaches the limit drive The movement path of the arm 804 is used to avoid the driving arm 804 from rotating when moving. The movement of the driving arm 804 will drive the limit plate 805 to move. The movement of the limit plate 805 will move toward the direction close to the collecting bag 806. When the limit plate 805 moves to a suitable position, it will squeeze the collecting bag 806 until the collecting bag 806 fits tightly against the surface of the sorting box 2. The movement of the limit plate 805 will drive the convex strip 807 to move. When the limit plate 805 squeezes the collecting bag 806 against the surface of the sorting box 2, the convex strip 807 will squeeze the collecting bag 806 into the limiting groove 808, thereby further improving the effect of limiting the collecting bag 806.
[0034] When the tightness of the transmission belt 7 needs to be adjusted, the latch 93 is first pulled. The movement of the latch 93 will move inside the fixed plate 91. The movement of the latch 93 will stretch the spring 98. At this time, the spring 98 is in a stretched state. The latch 93 will gradually come out of the circular groove 94 when moving. When the latch 93 comes out of the circular groove 94, the rectangular rod 92 is pushed. The movement of the rectangular rod 92 will move inside the fixed plate 91. The movement of the rectangular rod 92 will drive the pressure block 95 to move in the direction close to the transmission belt 7. The pressure block 95 will drive the rotating shaft to move and squeeze the transmission belt 7. When the transmission belt 7 rotates, it will drive the rotating shaft to rotate in the groove 96. The rotating shaft can reduce the friction between the pressure block 95 and the transmission belt 7. When the transmission belt 7 is adjusted to a suitable tightness, the latch 93 is released. The latch 93 will be inserted into the circular groove 94 with the help of the contraction force of the spring 98, thereby limiting the position of the pressure block 95.
