Detailed implementation mode

[0032] 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 efforts shall fall within the protection scope of the present invention.

[0033] Embodiment:

[0034] Please refer to Figure 1 - Figure 6 As shown, a fruit sorting device based on weighing for sorting includes:

[0035] A mounting frame 1, on the top of the mounting frame 1 is provided with a conveyor belt 2, and on the side wall of the mounting frame 1 is provided a driving assembly drivingly connected to the conveyor belt 2;

[0036] A guide plate 6, the guide plate 6 is fixedly installed at the end of the mounting frame 1;

[0037] A mounting plate 7, the mounting plate 7 is fixedly installed on one side of the mounting frame 1, and the mounting plate 7 is located below the guide plate 6. A screening assembly is fixedly connected to the mounting plate 7. The screening assembly includes a first weighing scale 8 fixedly connected to the mounting plate 7. On the top of the first weighing scale 8 is fixedly connected a column 9. At the top of the column 9 is fixedly connected a tray 10. A notch is formed on the surface of the tray 10, and a hinge plate 11 is hinged to the inner wall of each notch. The side wall of the column 9 is hinged with an electric telescopic rod 12, and the end of the electric telescopic rod 12 is hinged to the outer wall of the hinge plate 11;

[0038] A transfer assembly, there are multiple transfer assemblies, and all the multiple transfer assemblies are fixedly installed on the mounting plate 7;

[0039] The placing plates 18 are provided with a plurality of them. A roller 26 is rotatably connected to the bottom of the placing plate 18, and the plurality of placing plates 18 correspond to the transfer components one by one. A second weighing scale 19 is fixedly connected to the placing plate 18, and an acoustic-optic alarm cooperating with the second weighing scale 19 is fixedly connected to the placing plate 18. Connecting brackets 20 are fixedly connected to the side walls of the plurality of placing plates 18. A slide rail 21 is fixedly connected to the mounting frame 1 and is slidably connected to the connecting bracket 20 through the slide rail 21;

[0040] A reciprocating pushing component is arranged on the mounting frame 1.

[0041] As can be seen from the above, three placing plates 18 and three second weighing scales 19 can be set respectively. The three placing plates 18 are correspondingly used to collect apples of large, medium and small weights. The weights of large, medium and small are freely set by the staff according to the screening requirements and can be freely set according to different screening conditions. The staff place the apples on the conveyor belt 2, and the transfer component drives the conveyor belt 2 to move. The conveyor belt 2 drives the apples to be transferred to the guide plate 6 and then fall into the interior of the tray 10 via the guide plate 6. After the first weighing scale 8 weighs the apples in the tray 10, the electric telescopic rod 12 on one side is correspondingly activated. The electric telescopic rod 12 drives the hinge plate 11 to rotate. The apples in the tray 10 move along the hinge plate 11 and the transfer component towards the placing plate 18 and fall into the packaging box placed on the second weighing scale 19. The second weighing scale 19 weighs the total mass of the apples in the packaging box. When the total mass of the apples in the packaging box reaches the set standard, the acoustic-optic alarm emits an acoustic-optic alarm to prompt the staff, and the staff changes the box to continue loading apples. To prevent the apples from piling up inside the packaging box, the reciprocating pushing component can be intermittently activated. The reciprocating pushing component drives the placing plate 18 and the packaging box to shake, so that the apples inside the packaging box are evenly distributed.

[0042] The driving component includes a first motor 3 fixedly installed on the mounting frame 1. Chain wheels 4 are fixedly connected to the end of the output shaft of the first motor 3 and the end of the transmission shaft of the conveyor belt 2. A chain 5 is engaged on the two chain wheels 4. The output shaft of the first motor 3 drives the transmission shaft of the conveyor belt 2 to rotate through the chain wheel 4 and the chain 5, and the conveyor belt 2 rotates to convey the apples accordingly.

[0043] To make the apples inside the guide plate 6 accurately roll onto the tray 10, the guide plate 6 is provided with a constricted opening, that is, the opening at the end of the guide plate 6 close to the tray 10 is narrowed, and the guide plate 6 is trapezoidally arranged.

[0044] The bottom of the inner wall of the tray 10 is horizontally arranged, and the hinge position of the hinge plate 11 and the tray 10 is set at the horizontal position of the inner bottom wall of the tray 10. The apples falling inside the tray 10 will be at the horizontal bottom at the lowest part of the tray 10. When the hinge plate 11 rotates, the apples located at the horizontal bottom of the tray 10 will roll outwards along the rotating hinge plate 11.

[0045] The transfer assembly includes a vertical plate 13 fixedly installed on the mounting plate 7, a threaded rod 14 threadedly connected to the vertical plate 13, and a plug rod 15 slidably inserted into the vertical plate 13. The upper end of the plug rod 15 is fixedly connected to a conveying cylinder 16. The upper end of the threaded rod 14 is rotatably connected to the conveying cylinder 16. The upper end of the conveying cylinder 16 is open. The rotating hinge plate 11 will fall on the conveying cylinder 16, and the apples will be conveyed into the packing box through the conveying cylinder 16. When it is necessary to adjust the outlet landing point of the conveying cylinder 16 due to different heights of the packing box, the threaded rod 14 can be rotated. A displacement will be generated between the rotating threaded rod 14 and the vertical plate 13. The displaced threaded rod 14 will push up the conveying cylinder 16, thereby changing the position of the conveying cylinder 16. The plug rod 15 will slide inside the vertical plate 13 along with the change of the position of the conveying cylinder 16. The plug rod 15 and the threaded rod 14 cooperate to limit the degree of freedom of the conveying cylinder 16 and prevent the conveying cylinder 16 from rotating during the displacement process.

[0046] The reciprocating pushing assembly includes a connecting plate 22 fixedly installed on the connecting bracket 20. Two relatively coaxially arranged abutting rods 23 are fixedly connected to the connecting plate 22, and there is a gap between the ends of the two abutting rods 23. A second motor 24 is fixedly connected to the mounting frame 1. The end of the output shaft of the second motor 24 is fixedly connected to a turntable 25. The turntable 25 is inclined, and the side wall of the turntable 25 is inserted into the gap at the end of the abutting rod 23.

[0047] In order to avoid the accumulation of apples inside the packing box, the second motor 24 can be started to drive the turntable 25 to rotate. Since the turntable 25 is inclined, the rotating turntable 25 will drive the connecting plate 22 to perform a reciprocating motion through the abutting rod 23. The reciprocating connecting plate 22 drives the connecting bracket 20 to reciprocate on the slide rail 21. The connecting bracket 20 further drives the placing plate 18 and the packing box to reciprocate and shake, so that the apples falling inside the packing box roll evenly, avoiding the accumulation of apples.

[0048] As can be seen from the above, when classifying and packaging apples by weight, the apples are placed on conveyor belt 2. Conveyor belt 2 takes the apples to guide plate 6, and the apples roll into the interior of tray 10 via guide plate 6. The first weighing scale 8 detects the weight of the apples inside tray 10, and then determines which classification (large, medium, or small) the apples belong to according to the weighed weight. Then, the electric telescopic rod 12 is correspondingly activated to shorten. After the electric telescopic rod 12 shortens, it drives the hinge plate 11 to rotate. The apples inside tray 10 roll outwards along hinge plate 11 and into the interior of conveying cylinder 16, and then roll along conveying cylinder 16 into the packaging box on the second weighing scale 19. The second weighing scale 19 weighs the total mass of the apples inside the packaging box. When the total mass of the apples reaches a certain value, the staff can replace the packaging box. To prevent the apples from piling up inside the packaging box, the second motor 24 can be activated to drive the turntable 25 to rotate. The turntable 25 drives the connecting bracket 20 to reciprocate on the slide rail 21 through the abutting rod 23 and the connecting plate 22. The connecting bracket 20 then drives the placement plate 18 and the packaging box to reciprocate, so that the apples falling into the packaging box are evenly distributed. The control of the entire device is realized by using existing Internet of Things technology or computer technology. The operator controls the first motor 3, the first weighing scale 8, the electric telescopic rod 12, the second weighing scale 19, and the second motor 24 through a computer.
