Description

Technical Field

[0001] This utility model relates to the field of sorting equipment, and in particular to a sorting loading and unloading device. Background Technology

[0002] In the sorting of agricultural products, sorting machines are usually used for rapid sorting. For example, when sorting apples, roller sorting machines can separate apples of different sizes to facilitate subsequent packaging and sales. During sorting, the apples need to be poured onto the feeding device, which sends the apples to the sorting area. As the apples pass through different positions in the sorting area, they will fall onto the unloading device at different positions according to their size. The unloading device then sends the apples to the collection box.

[0003] For example, patent document CN211538596U discloses a fruit screening device. The device uses a roller elevator to lift and transport fruit placed on a hopper. The guide plate allows the fruit to smoothly enter the gradually increasing pitch roller grading machine. The pitch of the gradually increasing pitch screw on the roller grading machine gradually increases, driving the rollers to move forward in parallel. As the distance between the rollers increases, the product continuously falls from the gap between the two rollers onto the discharge conveyor, thereby achieving the purpose of sorting by size.

[0004] When loading apples into the roller sorting machine, the apples are usually poured into the hopper of the roller conveyor. The conveyor then tilts the apples upwards. During this process, the apples on the roller conveyor may pile up, and some apples will roll down again as they rise, causing them to collide with each other and potentially damage them. Moreover, when unloading, the apples fall directly downwards into the unloading device and collection box, and the falling apples may also bump and bruise, potentially damaging them. Utility Model Content

[0005] The purpose of this invention is to provide a sorting and loading / unloading device to solve the above-mentioned problems.

Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7 As shown, a sorting and loading / unloading device includes a base 1. A roller conveyor 2 and a roller sorter 3 are mounted on the top of the base 1. A loading hopper 4 is provided at the feed end of the roller conveyor 2. The loading hopper 4 is fixed to the top of the base 1 by support legs. Slide grooves 401 are provided on the two side walls of the loading hopper 4. A feeding mechanism 5 is provided inside the loading hopper 4. The feeding mechanism 5 includes two mounting seats 501, which are slidably connected in the slide grooves 401. A feeding shaft 502 is rotatably connected between the two mounting seats 501 by bearings. A feeding plate 503 is fixedly connected to the feeding shaft 502. A motor 504 is fixedly connected to one of the mounting seats 501 by screws. The output end of the motor 504 is fixed to the feeding shaft 502. The connection is made so that the motor 504 drives the feeding shaft 502 and the feeding plate 503 to rotate. The feeding plate 503 is a certain distance away from the inner bottom wall of the feeding hopper 4, so that the apples can pass under the feeding plate 503. The apples stacked on top will contact the feeding plate 503. During the rotation of the feeding plate 503, the apples stacked on top will be pushed to the right, thereby avoiding the apples from stacking on the roller conveyor 2. The cross section of the feeding plate 503 is arc-shaped, so that the feeding plate 503 can make gentle contact with the apples and avoid damage to the apples. An adjustment mechanism 6 for adjusting the height of the mounting base 501 is provided on one side of the feeding hopper 4. A feeding mechanism 7 is provided below the roller sorter 3, and a receiving mechanism 8 is provided below the feeding mechanism 7.

[0028] The adjusting mechanism 6 includes two bearing seats 601 distributed vertically. The bearing seats 601 are fixedly connected to one side of the feeding hopper 4 by screws. A lead screw 602 is rotatably connected between the bearing seats 601 via a bearing. An adjusting block 603 is threadedly connected to the lead screw 602. The adjusting block 603 is fixedly connected to the mounting seat 501 on the side away from the motor 504 by screws. Rotating the lead screw 602 causes the adjusting block 603 to drive the mounting seat 501 to move up and down, thereby adjusting the height of the feeding shaft 502 and changing the distance between the feeding plate 503 and the inner bottom wall of the feeding hopper 4 to adapt to different agricultural products and make it more versatile. A handwheel 604 is fixedly connected to the top of the lead screw 602, which allows for easy manual rotation of the lead screw 602.

[0029] The feeding mechanism 7 includes multiple guide frames 701, which are fixedly connected to the bottom of the roller sorter 3. A feeding hopper 702 is fixedly connected to the bottom front end of the guide frame 701, and a feeding pipe 703 is fixedly connected to the bottom of the feeding hopper 702. The apples sorted by the roller sorter 3 fall into different guide frames 701. The apples roll down the guide frames 701 into the feeding hopper 702 and the feeding pipe 703. The feeding pipe 703 discharges the apples. A collection frame can be placed below the feeding pipe 703 to collect the apples. The inner walls of the guide frames 701 and the feeding hopper 702 are provided with sponge pads 704 to reduce the impact intensity when the apples fall and prevent damage to the apples. A buffer mechanism 9 is provided inside the feeding pipe 703.

[0030] The buffer mechanism 9 includes a buffer plate 901 rotatably connected to the inner wall of the feed tube 703. The buffer plate 901 is inclined, and a spring 902 is fixedly connected between the bottom of the buffer plate 901 and the inner wall of the feed tube 703. When an apple enters the feed tube 703 and falls onto the buffer plate 901, the apple presses the buffer plate 901 to rotate, and the spring 902 is compressed. After passing between the buffer plates 901, the apple falls downward. The buffer plate 901 and the spring 902 can slow down the falling speed of the apple and reduce the impact force.

[0031] The receiving mechanism 8 includes a fixed plate 801, which is fixedly connected to the top of the base 1. Multiple hydraulic cylinders 802 are fixedly connected to the top of the fixed plate 801. A support plate 803 is fixedly connected to the output end of the hydraulic cylinders 802. When the collection frame is placed on the support plate 803, the hydraulic cylinders 802 adjust the height of the collection frame, thereby reducing the falling height of the apple relative to the collection frame, thus reducing the impact force on the apple in the collection frame after the apple falls, and further preventing damage to the apple.

[0032] Working principle: In use, the collection frame for collecting apples is placed on the support plate 803. The hydraulic cylinder 802 drives the collection frame to move upward, so that the inner bottom wall of the collection frame is close to the lower end of the discharge pipe 703, and the apples are poured into the feeding hopper 4. The motor 504 drives the material-pushing shaft 502 and the material-pushing plate 503 to rotate. During the rotation of the material-pushing plate 503, the apples stacked on top are pushed to the right, thereby preventing the apples from piling up on the roller conveyor 2. The apples sorted by the roller sorter 3 fall into different guide frames 701. The apples roll down the guide frames 701 into the discharge hopper 702 and the discharge pipe 703. Both 01 and the inner wall of the feeding hopper 702 are equipped with sponge pads 704 to reduce the impact intensity when the apples fall and prevent damage to the apples. The apples enter the feeding pipe 703 and fall onto the buffer plate 901. The apples press the buffer plate 901 to rotate, and the spring 902 is compressed. The apples fall downwards after passing between the buffer plates 901. The buffer plate 901 and the spring 902 can slow down the falling speed of the apples. Finally, the apples are discharged from the feeding pipe 703 and fall into the collection box. As the number of apples in the collection box increases, the hydraulic cylinder 802 gradually moves the collection box downwards, thus preventing the apples from falling from a high height and colliding with each other and causing damage.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
