[0003] Currently, when removing impurities such as leaves, chaff, dust, and shriveled grains from grains, cylindrical primary cleaning screens are generally used to quickly filter large particles. These devices typically have internal filter screens, but different types of materials (such as rapeseed, wheat, rice, and sorghum) require different diameters of the pores on the filter screen surface. Since the filter screens inside these devices are generally difficult to replace, it's hard to guarantee the filtration effect. Therefore, a new type of cylindrical primary cleaning screen is needed to solve these problems. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This embodiment provides a cylindrical primary cleaning screen, mainly used to address the issue that different material varieties (such as rapeseed, wheat, rice, sorghum, etc.) require different diameters of the small holes on the surface of the filter screen, and that the filter screens inside current equipment are generally difficult to replace. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0024] A cylindrical primary cleaning screen includes a processing chamber 1 with a rotating rod 2 rotatably inserted into its inner wall. In use, the user installs a filter screen 3 at one end of the rotating rod 2 via a connecting unit 4, and then controls the rotation of the rotating rod 2 via a drive unit 5 to drive the filter screen 3. Finally, the material is poured into the filter screen 3 to achieve rapid filtration. Prior to this, the user can select different specifications of filter screens 3 for filtration according to different materials. The main component of the processing chamber 1 is a main chamber body 101 with cleaning grooves 102 on both sides. During use... The user needs to feed the material into the main chamber 101 through the inlet 103 at one end of the main chamber 101, and then operate the connecting unit 4 through the mounting port 104 at the other end of the main chamber 101. The cleaning groove 102 allows the user to insert cleaning tools into the cleaning groove 102 to clean the filter screen 3 when cleaning is needed. It should be noted that when the filter screen 3 is filtering the material, the user needs to use the shielding unit 105 to shield the two cleaning grooves 102 and the mounting port 104 to prevent the filtered impurities from splashing. The main components are: a main mesh body 31 with several small holes on its surface, and an auger edge 32 (similar in principle to the spiral edge of an auger) on the inner wall of the main mesh body 31. Therefore, when material enters the main mesh body 31, it is driven by the auger edge 32 and moves within the main mesh body 31, thus achieving the purpose of filtering while simultaneously moving the material. The main component of the connecting unit 4 is a connecting rod 41 fixedly installed at one end of the main mesh body 31. During use, the user inserts the main mesh body 31 into the inner wall of the main chamber 101 while simultaneously inserting one end of the rotating rod 2 into the connecting rod 41. One end of the connecting rod 41 is connected to a connecting bolt 42, which is then threaded into the surface of the connecting rod 41. This allows the connecting bolt 42 to be threaded into the surface of the rotating rod 2, thus enabling the main mesh body 31 to be positioned and disassembled at one end of the rotating rod 2. The main components of the drive unit 5 are: a drive motor 51 fixedly installed on the surface of the main compartment 101. During use, the user controls the output end of the drive motor 51 to rotate through the controller 52 fixedly installed on the surface of the main compartment 101, which in turn drives the rotating rod 2 fixedly installed on the output end of the drive motor 51 to rotate, thereby further driving the main mesh body 31.

[0025] By inserting a rotating rod 2 inside the processing chamber 1, the user can connect one end of the rotating rod 2 to one end of the filter screen 3 via the connecting unit 4. Then, the user can control the rotating rod 2 to rotate via the drive unit 5, which will drive the filter screen 3 to rotate. Finally, the user can pour the material into the filter screen 3 to achieve the purpose of filtration. The filtered impurities will be discharged from the bottom of the processing chamber 1. The user can also replace the filter screen 3 with different specifications via the connecting unit 4 to suit different materials.

[0026] By providing a cleaning groove 102 on each side of the main chamber 101, the user can remove the obstruction of the cleaning groove 102 through the obstruction unit 105 during use, and then insert the cleaning tool into the cleaning groove 102 to clean the surface of the filter screen 3 to ensure its filtration efficiency.

[0027] like Figure 1 and Figure 2 As shown, in some embodiments, the main components of the shielding unit 105 are: two rotating plates 1051 respectively rotatably mounted on the inner walls of the two cleaning grooves 102. In use, the user rotates the two rotating plates 1051 and then pulls the two extension plates 1052 respectively, so that the two limiting protrusions 1053 respectively provided at one end of the two extension plates 1052 slide into the inner walls of the two cleaning grooves 102, thereby achieving full shielding of the two cleaning grooves 102. Since a cover plate 1054 is rotatably mounted on the inner wall of the mounting port 104, the user rotates the cover plate 1054 and attaches the magnetic sheet 1055 on the surface of the cover plate 1054 to the surface of the magnetic sheet 1055 on the inner wall of the mounting port 104. The mutual adsorption principle of the magnetic sheets 1055 is used to limit the cover plate 1054 on the inner wall of the mounting port 104.

[0028] like Figure 1 As shown, in some embodiments, a limiting frame 6 is fixedly installed on the surface of the main chamber 101. In use, the user slides and inserts a feeding hopper 7 into the inner wall of the limiting frame 6, and then slides and inserts a limiting rod 8 into the surface of the limiting frame 6, so that the surface of the limiting rod 8 abuts against the surface of the feeding hopper 7. Finally, a contact nut 9 is threaded onto the surface of the limiting rod 8, which can achieve stable limiting of the feeding hopper 7 on the inner wall of the limiting frame 6. Finally, the material is poured into the feeding hopper 7 to achieve the purpose of stable feeding. At the same time, two guide rods 10 are fixedly installed on the inner wall of the main chamber 101. After the user inserts the main mesh 31 into the interior of the main chamber, the main mesh 31 will fit against the surface of several contact wheels 11 (several contact wheels 11 are respectively rotated and sleeved on the surface of the two guide rods 10). During the subsequent rotation of the main mesh 31, several contact wheels 11 will rotate synchronously to ensure the stability of the main mesh 31 during rotation.

[0029] The working process of this utility model is as follows: First, the user needs to feed the material into the inside of the feed hopper 7. Then, the controller 52 controls the output end of the drive motor 51 to rotate, which drives the main mesh body 31 to rotate. The filtered impurities are discharged from the bottom of the main hopper body 101, and the processed material is discharged from the feed inlet 103 (under the action of the screw conveyor edge 32).

[0030] Secondly, users can assemble and disassemble the connecting rod 41 and the rotating rod 2 by using the connecting bolt 42. This allows users to select different specifications of the main mesh body 31 (the size of the surface holes) according to different materials during subsequent use, in order to ensure the filtration effect.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
