[0002] In the harvesting of agricultural products, the initial removal of impurities is a fundamental and crucial step. It not only ensures the purity of agricultural products and improves their appearance and internal quality, but also makes clean agricultural products easier to store and transport, effectively reducing losses in these stages. Furthermore, removing impurities simplifies subsequent processing procedures, reduces processing complexity, and thus improves overall processing efficiency. However, most existing impurity removal equipment relies on manual operation, which is not only inefficient but also consumes a lot of human resources.

[0003] Therefore, this utility model proposes a device for primary processing and impurity removal of agricultural products. Utility Model Content

[0004] The purpose of this invention is to provide a device for primary processing and impurity removal of agricultural products to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A primary processing and impurity removal device for agricultural products includes four sets of fixed support legs. Two sets of fixed support legs are fixedly connected to a connecting base rod on opposite sides. The top of the connecting base rod is fixedly connected to three sets of undulating slopes. Each side of the undulating slope is provided with a pulley mechanism. The three sets of pulley mechanisms are arranged in a linear array, and the height of the three sets of pulley mechanisms decreases sequentially. The top of each pulley mechanism is movably engaged with a connecting block, and the top of the connecting block is fixedly connected to a screen.

[0007] Three of the pulley mechanisms are movably sleeved with connecting rod 2 on their outer walls, and both ends of the two sets of connecting rod 2 are fixedly connected with connecting rod 1. A reciprocating mechanism is fixedly connected to the side of the connecting rod 1.

[0008] Furthermore, the reciprocating mechanism includes a motor, the outer wall of which is fixedly connected to a fixed support leg, a drive shaft is movably sleeved inside the fixed support leg, one end of the drive shaft is fixedly connected to the output end of the motor, the other end of the drive shaft is fixedly connected to a drive rod one, the outer wall of the drive rod one is fixedly connected to one end of a drive rod two, the other end of the drive rod two is hinged to a hinge block one, and the outer wall of the hinge block one is fixedly connected to a connecting rod one.

[0009] Furthermore, the top ends of two sets of fixed legs are fixedly connected to limit plates, and the limit plates have three sets of movable grooves inside, and each of the movable grooves is movably fitted with one set of pulley mechanisms.

[0010] Furthermore, the screen has several sets of filter holes inside, and the filter holes are arranged in a linear array.

[0011] Furthermore, the pulley mechanism includes a directional roller, the bottom end of which is in contact with the surface of the connecting base rod. The top end of the directional roller is provided with a movable support leg. Two sets of hinge blocks are fixedly connected to the outer wall of the movable support leg. Fixed blocks are hinged inside the two sets of hinge blocks. A connecting rod is fixedly connected to the bottom end of the fixed block. Springs are fixedly connected to the opposite sides of the two sets of connecting rods. The outer wall of the spring is movably sleeved with the movable support leg.

[0012] Furthermore, the connecting block has a limiting slot inside, and the inside of the limiting slot is movably engaged with the fixed block.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. The motor drives the transmission shaft to rotate inside one set of fixed support legs, causing transmission rod one to drive transmission rod two to move like a crank, which in turn causes hinge block one to pull connecting rod one, driving three sets of pulley mechanisms to slide at the top of the connecting base rod. Simultaneously, the three sets of pulley mechanisms slide at the top of the undulating slope, thus generating a vibration effect of up-and-down bumping and left-and-right movement. This vibrates the agricultural products placed on the top of the screen, removing impurities smaller than the screen mesh. The electric screening equipment is highly automated and efficient, quickly removing impurities and improving product purity. It also reduces manpower requirements and labor intensity, is easy to operate, and has stable performance, ensuring consistency and reliability in the screening process. Furthermore, the electric screening equipment has relatively low maintenance costs, is durable, and easy to clean and maintain.

[0015] 2. By pressing the two sets of connecting rods on three opposite sides, the fixing block rotates around the connection point of the hinge block two, making the top of the fixing block open. This releases the locking of the connecting block, allowing it to move from inside the movable support leg. This allows for the replacement of screens of different sizes. The installation and disassembly are simple, achieving the effect of quick screen replacement, improving the working efficiency and maintenance convenience of the equipment. Different screens can be replaced as needed to remove impurities from different crops. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1 to 4 As shown, the agricultural product primary processing and impurity removal device provided by this utility model includes four sets of fixed support legs 1, wherein two sets of fixed support legs 1 are fixedly connected to the opposite sides of a connecting base rod 3, and three sets of undulating slopes 4 are fixedly connected to the top of the connecting base rod 3. Each side of the undulating slope 4 is provided with a set of pulley mechanisms. The three sets of pulley mechanisms are arranged in a linear array, and the height of the three sets of pulley mechanisms decreases sequentially. Each pulley mechanism has a connecting block 15 movably engaged at the top of it, and a screen 16 is fixedly connected to the top of the connecting block 15.

[0025] Three sets of pulley mechanisms are movably sleeved with connecting rod 2 10 on their outer walls. Both ends of the two sets of connecting rod 2 10 are fixedly connected with connecting rod 1 9. A reciprocating mechanism is fixedly connected to the side of connecting rod 1 9.

[0026] The reciprocating mechanism includes a motor 2, the outer wall of which is fixedly connected to a fixed support leg 1. A transmission shaft 5 is movably sleeved inside the fixed support leg 1. One end of the transmission shaft 5 is fixedly connected to the output end of the motor 2. The other end of the transmission shaft 5 is fixedly connected to a transmission rod 6. One end of a transmission rod 7 is fixedly connected to the outer wall of the transmission rod 6. The other end of the transmission rod 7 is hinged to a hinge block 8. The outer wall of the hinge block 8 is fixedly connected to a connecting rod 9.

[0027] The top ends of the two sets of fixed support legs 1 are fixedly connected to limit plates 17. The limit plates 17 have three sets of movable grooves inside, and each set of movable grooves is movably fitted with one set of pulley mechanisms.

[0028] The screen 16 has several sets of filter holes inside, and the filter holes are arranged in a linear array.

[0029] Motor 2 drives transmission shaft 5 to rotate inside one set of fixed support legs 1, causing transmission rod 6 to drive transmission rod 7 to move in a curved position. This causes hinge block 8 to pull connecting rod 9, which in turn causes three sets of pulley mechanisms to slide at the top of connecting base rod 3. Simultaneously, the three sets of pulley mechanisms slide at the top of undulating slope 4, thus generating a vibration effect of up-and-down bumping and left-and-right movement. This vibrates the agricultural products placed on the screen 16, removing impurities smaller than the filter holes of the screen 16. The screening efficiency is high, and the manual labor requirement is reduced.

[0030] Example 2

[0031] Based on Example 1, please refer to Figures 1 to 4 As shown, the pulley mechanism includes a directional roller 18. The bottom end of the directional roller 18 is in contact with the surface of the connecting base rod 3. The top end of the directional roller 18 is provided with a movable support leg 11. Two sets of hinge blocks 19 are fixedly connected to the outer wall of the movable support leg 11. A fixing block 14 is hinged inside the two sets of hinge blocks 19. A connecting rod 13 is fixedly connected to the bottom end of the fixing block 14. A spring 12 is fixedly connected to the opposite side of the two sets of connecting rods 13. The outer wall of the spring 12 is movably sleeved with the movable support leg 11.

[0032] The connecting block 15 has a limiting slot inside, and the inside of the limiting slot is movably engaged with the fixed block 14.

[0033] When disassembly is required, press the two sets of connecting rods 13 toward opposite sides, causing the fixing block 14 to rotate around the connection point of the hinge block 19, making the top of the fixing block 14 open. Release the locking of the connecting block 15, and the connecting block 15 can be moved from inside the movable leg 11, allowing for the replacement of screens 16 of different sizes. Conversely, press the two sets of connecting rods 13 inwards, align the connecting block 15 with the top of the movable leg 11, and insert it. When the bottom of the connecting block 15 is in contact with the bottom of the inner wall of the movable leg 11, release the pressure on the connecting rods 13. Due to the elastic potential energy of the spring 12, the fixing block 14 resets and is inserted into the connecting block 15, securing it to prevent the screen 16 from separating from the pulley mechanism during vibration. Installation is simple and quick, and maintenance is convenient.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
