Description

Technical Field

[0001] The invention belongs to the technical field of vegetable processing, and in particular relates to a vegetable sorting production line and a defective product conveying mechanism. Background Art

[0002] In the vegetable industry, sorting is an indispensable part of the agricultural product packaging process. Vegetable sorting not only affects the final quality of the product, but also directly affects market sales and consumer satisfaction. Sorted defective vegetables generally need to be loaded onto transfer vehicles through conveying mechanisms or directly transported to garbage collection points outside the factory to avoid the impact of defective products on subsequent packaging and sales links.

[0003] Problems with existing technologies: When transporting the sorted defective products, they are generally not chopped, and the whole vegetables are transported on the conveying device. The excessive volume of vegetables will not only increase the difficulty of the transportation process, but also may cause the carrying capacity of the transfer vehicle or garbage collection point to quickly reach the upper limit, thereby limiting the number of defective vegetables that can be processed. In addition, no matter how many defective products are sorted out, they will directly enter the conveying device for continuous transportation without distinction. This lack of flexibility in processing methods causes the conveying device to have to operate continuously, and it is difficult to reasonably schedule according to actual needs. This practice not only increases the operating cost of the equipment, but also increases energy consumption, which is contrary to the current production concept of energy conservation, emission reduction and efficient operation. Summary of the invention

[0009] The rotating assembly includes an annular mounting block having an annular mounting groove on the inner side thereof, an annular gear being fixed on the outer wall of the storage plate and located in the mounting groove, a rotating shaft being rotatably installed passing through the interior of one of the shaft tubes, a third gear being meshed with the annular gear being fixed on one end of the rotating shaft, a third motor being fixed on the outer wall of the processing box, and an output shaft of the third motor being connected to one end of the rotating shaft via a second gear set.

An inclined plate is fixed on one side of the feed port for vegetables to fall smoothly onto the placement plate. Baffles are provided on both sides of the inclined plate to limit the position of the vegetables. A dividing leaf is rotatably installed between the two baffles near the feed port. A second motor connected to the dividing leaf is provided on one side of the baffle.

[0011] The processing box is cylindrical, and is provided with openings at the top and the bottom.

[0012] The first gravity sensor, the first hydraulic cylinder and the second hydraulic cylinder are all electrically connected to an external controller. The first gravity sensor detects the weight of the vegetables on the storage plate in real time. When the set weight value is reached, the weight value is set in advance by the controller, and the external controller controls the operation of the first hydraulic cylinder and the second hydraulic cylinder.

[0013] The second gravity sensor and the first motor are both electrically connected to an external controller. As long as one of the second gravity sensors detects the presence of vegetables, the external controller controls the first motor to operate.

[0014] A vegetable sorting production line comprises a vegetable sorting rack connected to a defective vegetable conveying mechanism and an inclined plate, a conveyor belt for sorting vegetables is arranged inside the vegetable sorting rack, a cylinder is arranged on one side of the vegetable sorting rack, an arc-shaped push plate for pushing defective vegetables onto the inclined plate is fixed to the output shaft of the cylinder, and a visual module for detecting defective vegetables is arranged on the top of the vegetable sorting rack above the arc-shaped push plate.

[0015] The technical effects achieved by the present invention are: The cutting knife provided in the present invention drives the first mounting block to move up and down through the first hydraulic cylinder, and then cooperates with the upper slider to slide along the reciprocating rotating groove. When the first mounting block drives the cutting knife to descend, the defective vegetables on the storage plate are cut. When the first mounting block drives the cutting knife to rise, the cutting knife is driven to rotate and the cutting position of the cutting knife is adjusted, so that the cutting angle of the cutting knife will be changed next time, and the vegetables will be cut into smaller pieces, which is convenient for the subsequent transportation of the chopped vegetables. In addition, the cutting knife is fan-shaped and has an opening in the middle, which can effectively prevent the cut defective vegetables from sticking to the cutting knife and affecting the normal cutting of the equipment next time.

[0016] The storage plate provided in the present invention has a first gravity sensor arranged in the arc-shaped groove, which can accurately sense the weight of defective vegetables accumulated on the storage plate. When the weight of these defective vegetables reaches a preset threshold, the external control system responds immediately and instructs the second motor to stop running, thereby making the dividing leaves stand still, thereby effectively blocking subsequent defective vegetables on the inclined plate to ensure that they cannot continue to slide onto the storage plate, and then the defective vegetables that fall onto the storage plate are chopped, thereby realizing on-demand processing and reasonable scheduling of defective vegetables, avoiding ineffective continuous operation of the conveying device, which not only greatly improves the processing efficiency, but also effectively saves the energy consumption of the equipment, and significantly reduces the overall operating cost.

[0017] The two second gravity sensors provided in the present invention are respectively installed in the feed trough of the base and at the end of the flexible conveying pipe. When the defective vegetables after crushing fall into the feed trough of the base, the built-in second gravity sensor can quickly capture their existence and immediately send a detection signal to the external controller. After receiving the signal, the controller immediately instructs the first motor to start and drives the flexible dragon to start rotating, so as to efficiently transport the defective vegetable fragments along the flexible conveying pipe and finally discharge them smoothly through the discharge head. When the two second gravity sensors fail to detect the trace of the defective vegetables, they will send a signal to the external controller again to instruct the first motor to stop working in time. This mechanism effectively prevents the first motor from running continuously in vain, greatly improves the energy utilization efficiency, and significantly reduces the overall operating cost of the equipment. In addition, the combination of the flexible conveying pipe and the flexible dragon realizes the flexible adjustment of the falling position of the fragments, greatly improves the convenience of operation, eliminates the tedious process of manual handling, and greatly promotes the smooth progress of the sorting work, significantly improving the work efficiency.

When the set weight value is reached, the weight value is set in advance by the controller, and the external controller controls the operation of the first hydraulic cylinder 4 and the second hydraulic cylinder 23.

[0024] According to the above structure, the first gravity sensor 17 is electrically connected to the external controller. When the first gravity sensor 17 detects that the defective vegetables falling on the placing plate 15 reach the set weight value, the external control controls the second motor 36 to stop working and stops the dividing blade 37 from rotating, blocking the defective vegetables on the inclined plate 35 so that the defective vegetables cannot fall on the placing plate 15. Then, the defective vegetables falling on the placing plate 15 are chopped.

At this time, the third motor is started by the external controller, and the third motor drives the rotating shaft 25 to rotate through the second gear set 24. The rotating shaft 25 drives the third gear 26 to rotate, and the third gear 26 drives the ring gear 27 to rotate. The ring gear 27 drives the placing plate 15 to rotate, so that the defective vegetables are evenly scattered on the placing plate 15, thereby improving the cutting effect of the vegetables.

As long as one of the second gravity sensors 34 detects the presence of vegetables, the external controller controls the first motor 30 to operate.

[0027] According to the above structure, when the defective vegetables after crushing fall into the feeding trough on the base 29, the presence of the defective vegetables is detected by the second gravity sensor 34 arranged inside, and the detection signal is transmitted to the external controller. The external controller controls the first motor 30 to start, and the first motor 30 drives the flexible dragon 31 to rotate, and makes the defective vegetable fragments move along the flexible conveying pipe 32 and be discharged from the discharge head 33. When the two second gravity sensors 34 cannot detect the presence of defective vegetables, the signal will be transmitted to the external controller again to control the first motor 30 to stop working, which can effectively avoid the continuous operation of the first motor 30, save energy, and reduce the operating cost of the equipment; the cooperation of the flexible conveying pipe 32 and the flexible dragon 31 can change the falling position of the fragments according to needs, and it is also convenient to transport the defective vegetables to the outdoor garbage collection point.

The slider 9 on the first mounting block 3 slides along the reciprocating rotation groove 11. When the first mounting block 3 descends, the slider 9 descends along the vertical groove and drives the cutting knife 8 to descend to cut the vegetables on the storage plate 15. When the first hydraulic cylinder 4 drives the first mounting block 3 to rise, it cooperates with the uphill platform 1 2, the slide block 9 is raised along the inclined slot, and drives the first mounting block 3 to rotate, thereby driving the cutting knife 8 to rotate, and adjusting the cutting position of the cutting knife 8. When the first mounting block 3 is driven down by the first hydraulic cylinder 4 again, the cutting position of the cutting knife 8 on the vegetables will be changed, which will make the vegetables cut more finely, and facilitate the subsequent transportation of the chopped vegetables. After the chopping is completed, the external controller controls the second hydraulic cylinder 23 to start, and the second hydraulic cylinder 23 drives the arc plate 22 to move. The arc plate 22 drives the tooth plate 20 to move through the connecting rod 21. The tooth plate 20 is meshed with the first gear 18, driving the shaft tube 13 to rotate. The shaft tube 13 drives the storage plate 15 on the annular mounting block 14 to flip 180 degrees, which is convenient for cleaning the vegetables on the storage plate 15. The storage plate 15 flips After rotation, the other side of the storage plate 15 faces upward, and the external controller controls the second motor 36 to work.
