[0038] In this embodiment, ifFigure 1 and Figure 2 As shown in Figure 2 , a pellet sieve with a screen that is easy to replace includes a pellet sieve body 1 and a screen 11. The screen 11 is installed in the inner cavity of the pellet sieve body 1. An installation component 2 is provided on the pellet sieve body 1. The installation component 2 is used to replace the screen 11. The installation component 2 includes an installation seat 21, a support shaft 22, a plug board 23, and a driving component 24. The installation seat 21 is rotatably connected to the pellet sieve body 1 through the support shaft 22. The plug board 23 is inserted into the limit slot of the installation seat 21. The plug board 23 is fixedly connected to the screen 11. The driving component 24 is used to drive the support shaft 22. By driving the driving component 24, the support shaft 22 together with the installation seat 21 rotates. Then, the screen 11 rotates clockwise in the pellet sieve body 1 to discharge the retained material. When the screen 11 and the pellet sieve body 1 are in a vertical state, the plug board 23 is separated from the limit slot of the installation seat 21, and then the screen 11 is disassembled and replaced.

[0039] Thus, the screen 11 is arranged in parallel in the cavity of the pellet sieve body 1. The material is screened on the screen 11. Under the action of the driving component 24, the support shaft 22 rotates in the pellet sieve body 1. The installation seat 21 moves together with the support shaft 22. When the screen 11 and the pellet sieve body 1 are perpendicular, the residual material on the screen 11 is automatically discharged. The plug board 23 is horizontally moved to be separated from the limit slot of the installation seat 21, and the disassembly of the screen can be completed.

[0040] Furthermore, the screen 11 is arranged at the bottom of the cavity of the pellet sieve body 1. The support shaft 22 rotates in the pellet sieve body 1 through a bearing. A limit slot adapted to the plug board 23 is machined in the installation seat 21. The plug board 23 is inserted into the limit slot of the installation seat 21 to realize the connection between the screen 11 and the installation seat 21.

[0041] In some embodiments, as Figure 3 shown, the driving component 24 includes a gear 241, a rack 242, a telescopic component 243, and a connecting component 244. The gear 241 is fixedly connected to both ends of the support shaft 22. The rack 242 is meshed with the gear 241. The output end of the telescopic component 243 is fixedly connected to the rack 242. The telescopic component 243 is connected to the pellet sieve body 1 through the connecting component 244. The rack 242 moves horizontally to drive the gear 241 and the support shaft 22 to rotate.

[0042] Furthermore, gears 241 are arranged at both ends of the support shaft 22. The rack 242 is used to drive the gear 241 to rotate. The telescopic component 243 is a hydraulic rod. The connecting component 244 fixes the telescopic component 243 on the side wall of the pellet sieve body 1

[0043] In some embodiments, as Figure 5As shown in the figure, a bearing assembly 3 is installed on the granular material sieve body 1. The bearing assembly 3 is used to drive the granular material sieve body 1 to vibrate. The bearing assembly 3 includes a support plate 31, a bearing frame 32, an elastic member 33 and a power member 34. The support plate 31 is rotatably connected to the granular material sieve body 1 through a pin shaft. The bearing frame 32 is fixedly connected to the bottom of the support plate 31. The upper and lower ends of the elastic member 33 are respectively connected to the granular material sieve body 1 and the bearing frame 32. The power member 34 is used to drive the granular material sieve body 1 to move upward, and the elastic member 33 pulls the granular material sieve body 1 to reset, thereby realizing the vibration of the granular material sieve body 1.

[0044] Further, there are two support plates 31. The granular material sieve body 1 rotates around the support plate 31. The bearing frame 32 is used to support the overall mechanism. A cavity is machined inside the bearing frame 32. The elastic member 33 is a tension spring. The elastic member 33 connects the granular material sieve body 1 and the bearing frame 32 together. The design of the elastic member 33 facilitates the reset of the granular material sieve body 1.

[0045] In some embodiments, as Figure 1 and Figure 5 shown, the power member 34 includes a bracket 341, a connecting shaft 342, a cam 343 and a motor 344. The bottom end of the bracket 341 is fixedly connected to the bearing frame 32. The cam 343 is rotatably connected to the bracket 341 through the connecting shaft 342. The outer periphery of the cam 343 abuts against the granular material sieve body 1. The output end of the motor 344 is fixedly connected to the connecting shaft 342.

[0046] Further, the bracket 341 is processed into a U shape. The connecting shaft 342 rotates in the bracket 341 through a bearing. The outer wall of the cam 343 is processed with triangular protrusions. The motor 344 is used to drive the connecting shaft 342 to rotate.

[0047] In some embodiments, as Figure 4 shown, a feeding assembly 4 is arranged on the bearing frame 32. The feeding assembly 4 is used to sprinkle materials into the granular material sieve body 1. The feeding assembly 4 includes a sliding plate 41, a sliding rod 42, a placing plate 43 and a feeding member 44. The bottom end of the sliding plate 41 is fixedly connected to the bearing frame 32. The sliding rod 42 is slidably connected to the sliding plate 41. The placing plate 43 is fixed on the sliding rod 42. The sliding rod 42 drives the feeding member 44 to move horizontally through the placing plate 43. The feeding member 44 is used to add materials to the granular material sieve body 1.

[0048] Further, there are two sliding rods 42. A through groove adapted to the sliding rod 42 is arranged in the sliding plate 41. The placing plate 43 is used to support the feeding member 44. The movement of the sliding rod 42 in the sliding plate 41 facilitates the adjustment of the feeding position of the feeding member 44 into the granular material sieve body 1.

[0049] In some embodiments, as Figure 4As shown, the feeding part 44 includes a blanking pipe 441, a storage hopper 442, and a control valve 443. The blanking pipe 441 is fixedly connected to the cavity of the placing plate 43. The bottom of the storage hopper 442 is communicated with the blanking pipe 441. The control valve 443 is used to control the opening and closing of the blanking pipe 441.

[0050] Furthermore, the placing plate 43 drives the blanking pipe 441 to move. The storage hopper 442 is used to store materials. The use of the control valve 443 facilitates the control of the opening and closing of the blanking pipe 441.

[0051] In some embodiments, as Figure 3 shown, a guiding rod 231 is inserted into the inserting plate 23, and the guiding rod 231 is fixedly connected to the mounting seat 21.

[0052] Furthermore, the guiding rod 231 is arranged in the limiting groove of the mounting seat 21. The arrangement of the guiding rod 231 makes the connection between the inserting plate 23 and the limiting groove of the mounting seat 21 more stable.

[0053] In some embodiments, as Figure 3 shown, the connecting piece 244 includes a clamp 244a and a bolt 244b. The clamp 244a is fixedly connected to the telescopic piece 243. The clamp 244a is connected to the mounting seat 21 through the bolt 244b.

[0054] Furthermore, the use of the clamp 244a and the bolt 244b fixes the telescopic piece 243 on the side wall of the granular material sieve body 1.

[0055] In some embodiments, as Figure 4 shown, a top pin 411 is installed in the sliding plate 41. The top pin 411 is used to fix the position of the sliding rod 42 in the sliding plate 41.

[0056] Furthermore, the position of the sliding rod 42 in the sliding plate 41 is fixed by the top pin 411. The top pin 411 is rotated to separate from the sliding rod 42. By horizontally reciprocating the sliding rod 42 in the sliding plate 41, the sliding rod 42 drives the feeding part 44 to reciprocate, facilitating uniform filling of the granular material sieve body 1.

[0057] In some embodiments, as Figure 3 shown, a trapezoidal protrusion is machined on the side wall of the mounting seat 21 for guiding the materials remaining on the sieve mesh 11.

[0058] Furthermore, the trapezoidal protrusion provided on the side wall of the mounting seat 21 is used to guide the materials remaining on the sieve mesh 11, facilitating discharging.

[0059] The working principle of the present application will be described below with a relatively optimal embodiment:

[0060] Start the motor 344. The motor 344 drives the connecting shaft 342 to rotate in the bracket 341 through the coupling. Then, the cam 343 rotates together with the connecting shaft 342. When the protrusion of the cam 343 pushes the granular material sieve body 1 to move around the support plate 31, the granular material sieve body 1 stretches the elastic member 33. When the protrusion of the cam 343 separates from the granular material sieve body 1, the granular material sieve body 1 is pulled back under the action of the elastic member 33. Thus, the granular material sieve body 1 is in a vibrating state. Subsequently, move the sliding rod 42 in the sliding plate 41. The sliding rod 42 drives the placement plate 43 and the storage hopper 442 to move. Open the control valve 443. Then, the material in the storage hopper 442 falls into the cavity of the granular material sieve body 1 through the feeding pipe 441. The material is sorted through the sieve mesh 11. When the material sorting is completed, start the telescopic member 243. The output end of the telescopic member 243 drives the rack 242 to move horizontally. The rack 242 drives the gear 241 and the support shaft 22 to rotate. When the sieve mesh 11 and the granular material sieve body 1 are in a vertical state, the material remaining on the sieve mesh 11 is led out through the side wall of the mounting seat 21. Subsequently, horizontally move the insertion plate 23 in the limiting groove of the mounting seat 21. The insertion plate 23 drives the sieve mesh 11 to separate from the mounting seat 21. Thus, the sieve mesh 11 is replaced.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
