The traditional screening step is to let people screen manually and screen the size of crops. This requires a lot of human resources, is time-consuming and labor-intensive, and during manual screening, manual operation has a fatigue period, which leads to a decrease in the screening effect of agricultural products.

[0003] In the existing technical solutions, such as a screening device for agricultural product processing with application number: 201921769671.9, it includes a rectangular box body, on which a screening structure is provided; the screening structure includes: several servo motors and multiple partitions; a rectangular through hole is opened on the upper wall of the rectangular box body, and a plurality of first circular grooves are opened on the left side of the rectangular through hole.

[0004] In the above, the screening and dropping of agricultural products are basically achieved through the coordinated arrangement of multiple partitions and rectangular through holes, but the partitions and the baffles adapted to the partitions in the device are fixedly arranged, which cannot meet the regional screening needs of mixed agricultural products, and further cannot meet the quantitative screening needs of agricultural products.

[0027] Example 1

[0028] Reference Figure 1-2 , which is the first embodiment of the present utility model, provides a screening device for agricultural product processing, including a positioning frame 102, the positioning frame 102 is equipped with a drying mechanism 200 and an auxiliary mechanism 300;

[0029] In addition, the drying mechanism 200 includes a sheet metal seat 201 fixedly connected to the upper surface of the positioning frame 102, the top of the sheet metal seat 201 is rotatably connected to a hinge 202, the upper surface of the hinge 202 is adapted to be installed with a top plate 203, the surface of the top plate 203 is fixedly penetrated by a stepper motor 204, the output end of the stepper motor 204 is plugged with a transmission disk 206, and the side of the stepper motor 204 is adapted to be installed with a stabilizing member 205, the transmission disk 206 is rotatably sleeved with a transmission rod 207 through the top plug-in shaft, one end of the transmission rod 207 is rotatably connected to a universal joint seat 208, and the universal joint seat 208 is cooperated with a screen 209.

[0030] Specifically, the positioning frame 102 is arranged in coordination with the drying mechanism 200 and the auxiliary mechanism 300, so that the device can maintain stability when screening agricultural products. At the same time, the rotation connection between the sheet metal seat 201 and the hinge 202 can evenly absorb the vibration generated by the screen 209 when screening agricultural products. The stepper motor 204 is fixedly connected to the top plate 203, so that the stepper motor 204 will not jump violently up and down when outputting power. The connection between the transmission disk 206 and the stepper motor 204 can transmit the power at the output end of the stepper motor 204, and it is also convenient In order to facilitate the rotation and screening of the screen 209, the adaptive installation of the fixing part 205 and the stepper motor 204 can prevent the side of the stepper motor 204 from shifting, thereby affecting the screening function of the screen 209. The rotation connection between the transmission rod 207 and the transmission disk 206 allows the rotational torque to be finally transmitted to the transmission rod 207. The direct transmission method also reduces energy loss. The matching setting of the screen 209 and the universal joint seat 208 allows the screen 209 to remain stable when the angle is rotated, meeting the demand for accurate screening of mixed agricultural products and improving screening efficiency.

[0031] Furthermore, a cross frame 210 is fixedly connected to the side of the universal joint seat 208, the inner side of the cross frame 210 is snap-connected to the screen 209, and a coupling 211 is provided on the lower surface of the cross frame 210 through an adapter shaft fixing sleeve, and a base 212 is inserted into the end face of the coupling 211.

[0032] Preferably, the fixed connection between the cross frame 210 and the universal joint seat 208 ensures that all sides of the screen 209 are evenly stressed, and the screen 209 will not be squeezed and deformed. The fixed sleeve of the coupling 211 and the cross frame 210 allows the cross frame 210 to be positioned in a suitable position, which facilitates the quantitative screening requirements of agricultural products. The connection between the base 212 and the coupling 211 ensures that the coupling 211 always maintains good concentricity, while also improving the stable screening ability of the screen 209.

[0035] Example 2

[0036] Reference Figure 2-3, which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts to achieve stable screening and stabilizing effect of the screen 209.

[0037] Specifically, a plurality of circular holes are formed on the surface of the screen 209 , and the plurality of circular holes are arranged at equal intervals on the screen 209 . An overflow block 214 is clamped on the side of the blanking box 213 .

[0038] Furthermore, the multiple circular holes formed in the screen 209 allow the mixed agricultural products to be stably screened by the circular holes, which reflects the flexibility of screening. The overflow block 214 is connected to the blanking box 213. When the agricultural products flow out through the overflow block 214, the stepper motor 204 is stopped immediately, so that the falling flow rate of the agricultural products can be appropriately regulated.

[0039] Preferably, the auxiliary mechanism 300 includes a column 301, the side of the column 301 is fixedly connected to the screen 209, the outer side of the column 301 is fixedly sleeved with a bent plate 302, the end face of the bent plate 302 is movably clamped with a straight tooth 303, and the side of the straight tooth 303 is fixedly connected to the screen 209 through a top shaft.

[0040] Among them, the fixed connection between the column 301 and the screen 209 supports the movable clamping of the bent plate 302, and the clamping of the bent plate 302 and the straight teeth 303 further provides support and stability for the front side of the screen 209, making it convenient to adjust the position of the screen 209.

[0041] Example 3

[0042] Reference Figure 2-5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for realizing the splicing and screening of the screen 209 and the stable placement of the cross frame 210.

[0043] Specifically, the shape of the screen 209 is set to be an assembled structure with an inclined surface, and an inward plate is provided at the edge of the screen 209.

[0044] Furthermore, the inclined structure of the screen 209 allows the agricultural products to roll down smoothly, facilitating the collection of the materials after screening.

[0047] Working principle: First, spray the agricultural products evenly on the surface of the screen 209, then clamp the screen 209 on the inner side of the cross frame 210, and then start the stepper motor 204. The stepper motor 204 will move the power transmission disc 206 and the transmission rod 207, and then plug and fix the universal joint seat 208 and the end face of the transmission rod 207, and plug and fix the cross frame 210 and the side of the transmission rod 207. Then, let the base 212 and the coupling 211 be fixed, and the cross frame 210 is used to The placement on the side is fixed; when the screen 209 is stably screening on the positive side, the bent plate 302 is fixedly mounted on the side of the column 301, and then the bent plate 302 is movably engaged with the straight teeth 303 for stable placement of the screen 209; when the screen 209 needs to be displaced to screen the material, the stepper motor 204 helps the angle position of the screen 209 through the direction adjustment effect of the universal joint seat 208, and further screens the material through the circular holes opened in the screen 209, and finally falls to the blanking box 213 for collection and sorting.
