Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a screening machine for microbial fertilizer processing. Background Technology

[0002] The application of microbial fertilizers is becoming increasingly widespread in agricultural production and ecological construction. They can improve soil structure, enhance plant disease resistance, and increase crop yields. Screening is a crucial step in the production of microbial fertilizers to meet product quality standards and application requirements.

[0003] Currently, commonly used screening equipment is mostly vibrating screens or rotary screens. These devices use mechanical vibration or rotation to force fertilizer through the screen, thus achieving screening. However, these screening devices have certain limitations for larger pieces of material commonly found in microbial fertilizer production. Larger pieces of microbial fertilizer need to be manually kneaded to break them up and disperse them, which increases labor costs and affects screening efficiency.

[0004] Therefore, a microbial fertilizer processing screening machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a microbial fertilizer processing screening machine in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A microbial fertilizer processing screening machine includes a screening box, a guide frame fixedly installed on the inner wall of the screening box, and a movable frame slidably installed inside the guide frame. An arc-shaped screening mesh is fixedly installed on the inner wall of the movable frame for screening microbial fertilizer. A reciprocating swing assembly is provided on the surface of the screening box and the surface of the movable frame to make the movable frame swing laterally back and forth within the guide frame. A crushing assembly is fixedly installed on the inner top of the screening box to crush and disperse large pieces of microbial fertilizer on the arc-shaped screening mesh.

[0008] Furthermore, a hopper is provided on the top surface of the screening box, a discharge plate is installed obliquely on the inner wall of the screening box, the discharge plate is located below the arc-shaped screening mesh, and a window is hinged to the side wall of the screening box.

[0009] Furthermore, the reciprocating oscillating assembly includes a mounting frame fixedly installed on the other side wall of the screening box, and a motor is fixedly installed on the top surface of the mounting frame. The output end of the motor is fixedly connected to a cam through the mounting frame, and the cam is in contact with the end face of the movable frame. A plug rod is fixedly installed on the other end face of the movable frame. The plug rod is movably plugged into the movable frame. A first spring is sleeved on the surface of the plug rod. The two ends of the first spring are fixedly connected to the opposite faces of the movable frame and the guide frame, respectively.

[0010] Furthermore, the rolling assembly includes two sets of sleeve rods fixedly installed on the top inner side of the screening box, and a stepped rod is movably inserted into the bottom end of the sleeve rod. A mounting seat is fixedly installed at the bottom end of the stepped rod. A second spring is sleeved on the surface of the sleeve rod and the stepped rod. The two ends of the second spring are respectively fixed to the top inner side of the screening box and the end face of the stepped rod. Rolling rollers are rotatably inserted into the two sets of mounting seats.

[0011] Furthermore, the rolling roller is in contact with the surface of the arc-shaped screening screen, and when the movable frame and the arc-shaped screening screen move laterally, the rolling roller is rolled on the top surface of the arc-shaped screening screen.

[0012] Furthermore, the surface of the rolling roller is provided with a pattern along its axial direction, and the mounting base and the rolling roller are located inside the arc-shaped screening screen, with the mounting base sliding against the inner wall of the movable frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] By setting up an arc-shaped screening screen and crushing components, larger pieces of microbial fertilizer can be automatically crushed and dispersed without manual kneading, which significantly improves screening efficiency and reduces labor costs.

[0015] The cam is driven by an electric motor to rotate, causing the movable frame and the arc-shaped screening screen to move laterally back and forth within the guide frame, which enhances the screening effect and improves the screening efficiency.

[0016] The crushing roller rolls on the surface of the arc-shaped screening screen, applying pressure and crushing large pieces of microbial fertilizer. The patterned design on the surface of the crushing roller increases the friction with the fertilizer, further improving the crushing effect. Attached Figure Description

[0027] like Figures 1 to 5As shown, a microbial fertilizer processing screening machine includes a screening box 1, a guide frame 2 fixedly installed on the inner wall of the screening box 1, and a movable frame 3 slidably installed inside the guide frame 2. An arc-shaped screening mesh 4 is fixedly installed on the inner wall of the movable frame 3 for screening microbial fertilizer. A reciprocating swing component 5 is provided on the surface of the screening box 1 and the surface of the movable frame 3 to make the movable frame 3 swing laterally back and forth inside the guide frame 2. A crushing component 6 is fixedly installed on the inner top of the screening box 1 to crush and disperse large pieces of microbial fertilizer on the arc-shaped screening mesh 4. More specifically, by adding microbial fertilizer into the screening box 1, the microbial fertilizer falls onto the top surface. The reciprocating swing component 5 causes the movable frame 3 and the arc-shaped screening screen 4 to move laterally back and forth inside the guide frame 2. While the movable frame 3 and the arc-shaped screening screen 4 are moving laterally back and forth, the crushing component 6 rolls relative to the top surface of the reciprocating swing component 5, thereby crushing and dispersing the large pieces of microbial fertilizer accumulated on the top surface of the arc-shaped screening screen 4.

[0028] The top surface of the screening box 1 is provided with a hopper 11, and the inner wall of the screening box 1 is inclinedly installed with a discharge plate 12, which is located below the arc-shaped screening screen 4. A window is hinged to the side wall of the screening box 1. More specifically, the hopper 11 on the top surface of the screening box 1 allows microbial fertilizer to be added to the top surface of the arc-shaped screening screen 4, and the discharge plate 12 on the inner wall of the screening box 1 allows the screened microbial fertilizer to be discharged.

[0029] The reciprocating oscillating assembly 5 includes a mounting frame 501 fixedly installed on the other side wall of the screening box 1, and a motor 502 fixedly installed on the top surface of the mounting frame 501. The output end of the motor 502 passes through the mounting frame 501 and is fixedly connected to a cam 503. The cam 503 is in contact with the end face of the movable frame 3, and a plug rod 504 is fixedly installed on the other end face of the movable frame 3. The plug rod 504 is movably plugged into the movable frame 3. A first spring 505 is sleeved on the surface of the plug rod 504. The two ends of the first spring 505 are fixedly connected to the opposite faces of the movable frame 3 and the guide frame 2, respectively. More specifically, the motor 502 drives the cam 503 to rotate, and the cam 503 is in contact with one end face of the movable frame 3. When the cam 503 contacts the end face of the movable frame 3 from bottom to top, it pushes the movable frame 3 and the arc-shaped screening screen 4 laterally inside the guide frame 2, compressing the first spring 505. When the cam 503 contacts the end face of the movable frame 3 from top to bottom, the elastic force of the first spring 505 causes the arc-shaped screening screen 4 and the movable frame 3 to move in opposite directions inside the guide frame 2, thereby realizing the lateral reciprocating movement of the movable frame 3 and the arc-shaped screening screen 4.

[0030] The crushing assembly 6 includes two sets of sleeve rods 601 fixedly installed on the top inner side of the screening box 1, and a step rod 602 is movably inserted into the bottom end of the sleeve rod 601. A mounting seat 603 is fixedly installed on the bottom end of the step rod 602. A second spring 604 is sleeved on the surface of the sleeve rod 601 and the step rod 602. The two ends of the second spring 604 are fixed to the top inner side of the screening box 1 and the end face of the step rod 602, respectively. A crushing roller 605 is rotatably inserted into the two sets of mounting seats 603. More specifically, as the roller 605 is attached to the top surface of the arc-shaped screening screen 4, and the movable frame 3 and the arc-shaped screening screen 4 move laterally back and forth, the roller 605 comes into contact with the microbial fertilizer on the top surface of the arc-shaped screening screen 4. The roller 605 crushes the microbial fertilizer, causing the roller 605 to be lifted by large pieces of microbial fertilizer. This causes the roller 605, the mounting base 603, and the step rod 602 to move vertically along the sleeve rod 601, thereby compressing the second spring 604. Conversely, under the elastic force of the second spring 604, the roller 605 applies pressure and crushes the large pieces of microbial fertilizer, thus dispersing the large pieces of microbial fertilizer.

[0031] The pressing roller 605 is in contact with the surface of the arc-shaped screening screen 4. When the movable frame 3 and the arc-shaped screening screen 4 move laterally, the pressing roller 605 is rolled on the top surface of the arc-shaped screening screen 4. More specifically, by the pressing roller 605 being in contact with the surface of the arc-shaped screening screen 4, the microbial fertilizer on the top surface of the arc-shaped screening screen 4 can be pressed.

[0032] The surface of the roller 605 is patterned along its axial direction, and the mounting base 603 and the roller 605 are located inside the arc-shaped screening screen 4, with the mounting base 603 sliding against the inner wall of the movable frame 3. More specifically, the pattern on the surface of the roller 605 increases the friction with the microbial fertilizer, enabling the microbial fertilizer to be crushed and dispersed.

[0033] In summary: By adding microbial fertilizer into the screening box 1, the microbial fertilizer falls onto the top surface. The reciprocating oscillating component 5 causes the movable frame 3 and the arc-shaped screening screen 4 to move laterally back and forth inside the guide frame 2. While the movable frame 3 and the arc-shaped screening screen 4 are moving laterally back and forth, the crushing component 6 rolls relative to the top surface of the reciprocating oscillating component 5, thereby crushing and dispersing the large pieces of microbial fertilizer accumulated on the top surface of the arc-shaped screening screen 4.

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 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. The scope of protection of this utility model is defined by the appended claims and their equivalents.
