[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-6 , the present invention provides an agricultural crop weighing device, including an electronic scale 1. A weighing box 2 is arranged on the top of the electronic scale 1. A processing box 3 is arranged in the inner cavity of the weighing box 2. A positioning component for fixing the processing box 3 is arranged on the surface of the weighing box 2. The positioning component includes four groups of card strips 8 fixedly installed in the inner cavity of the weighing box 2. The inner sides of the four groups of card strips 8 are all attached to the surface of the processing box 3. A positioning rod 9 is threadedly connected to one side of the weighing box 2. One end of the positioning rod 9 penetrates through the weighing box 2 and extends into the inner cavity of the weighing box 2 to be attached to the surface of the processing box 3.

[0022] Through the setting of the positioning component, the processing box 3 can be installed and fixed in the inner cavity of the weighing box 2. During installation, the user can insert the bottom of the processing box 3 between the four groups of card strips 8, and then tighten the positioning rod 9 to lock and fix the processing box 3 in the inner cavity of the weighing box 2.

[0023] Preferably, a feeding hopper 5 is fixedly installed on the top of the processing box 3. An inclined sieve plate 6 is arranged in the inner cavity of the processing box 3. Discharge chutes 4 are arranged on both sides of the processing box 3 located in the inner cavity of the weighing box 2. The sieve plate 6 is movably installed in the inner cavity of the processing box 3 through an elastic connection component. The elastic connection component includes fixed blocks 10 fixedly installed at the four corners of the sieve plate 6. Support blocks 11 are fixedly installed in the inner cavity of the processing box 3 and directly below the fixed blocks 10. A compression spring 12 is fixedly installed on the top of the support block 11. The top end of the compression spring 12 is fixedly connected to the bottom of the fixed block 10.

[0024] Through the setting of the elastic connection component, when the user pours crops into the processing box 3 through the feeding hopper 5, the crops will fall on the surface of the sieve plate 6. Under the impact of the crops, the sieve plate 6 will move downward, thereby compressing the compression spring 12. The reaction force generated by the contraction of the compression spring 12 will push the sieve plate 6 upward to reset. The reciprocating vibration of the sieve plate 6 can accelerate the movement of the crops.

[0025] Among them, a guiding component for improving the moving stability of the sieve plate 6 is also arranged between the fixed block 10 and the supporting block 11. The guiding component includes a guiding rod 13 fixedly installed at the bottom of the fixed block 10. A guiding hole 14 adapted to the guiding rod 13 is formed on the surface of the supporting block 11. The surface of the guiding rod 13 is slidably connected to the inner wall of the guiding hole 14. Through the setting of the guiding component, the moving stability of the sieve plate 6 can be improved. When the sieve plate 6 moves, it will drive the guiding rod 13 to slide in the inner cavity of the guiding hole 14.

[0026] It is worth noting that a blowing component is arranged inside the processing box 3 and on one side of the sieve plate 6. The blowing component includes a support plate 15 fixedly installed inside the processing box 3. A blowing shell 16 is fixedly installed on the side of the support plate 15 close to the sieve plate 6. Nozzles 17 are arrayedly installed on the surface of the blowing shell 16. A blower 18 is fixedly installed on one side of the processing box 3. The exhaust end of the blower 18 is communicated with a connecting pipe 19. One end of the connecting pipe 19 away from the blower 18 sequentially penetrates through the processing box 3 and the support plate 15 and is communicated with the surface of the blowing shell 16. A waste discharge pipe 7 is fixedly connected to one side of the processing box 3 and on the other side of the sieve plate 6.

[0027] Through the setting of the blowing component, when the crops fall on the surface of the sieve plate 6, the blower 18 extracts external air and enters the blowing shell 16 through the connecting pipe 19, and blows it out at high speed to the outside, blowing out the dust and impurities mixed in the crops and discharging them to the outside through the waste discharge pipe 7.

[0028] Furthermore, a filtering component is fixedly connected to the air inlet end of the blower 18. The filtering component includes a mounting pipe 20 fixedly installed at the air inlet end of the blower 18. A filter net 21 is fixedly installed inside the mounting pipe 20. Through the setting of the filtering component, the air inhaled by the blower 18 can be filtered.

[0029] Even further, a box door 22 is hinged to one side of the weighing box 2. A locking frame 23 is fixedly installed on the surface of the box door 22. A locking rod 24 is threadedly connected to the surface of the locking frame 23. One end of the locking rod 24 penetrates through the locking frame 23 and extends to the outside of the locking frame 23 and is threadedly connected to the surface of the weighing box 2. Through the setting of the box door 22, the box door 22 can be opened to take out the crops after weighing. Through the cooperation of the locking rod 24 and the locking frame 23, the box door 22 can be locked and fixed.
