Description

Technical Field

[0001] This utility model belongs to the field of organic fertilizer raw material processing technology, and in particular relates to an organic fertilizer raw material processing and screening equipment. Background Technology

[0002] Organic fertilizer raw material processing and screening equipment is a key piece of equipment in the organic fertilizer production process. It is used to separate impurities, uncomposted materials and particles of different sizes from the raw materials to ensure fertilizer quality and uniformity.

[0003] Traditional organic fertilizer raw material processing and screening usually uses a drum screen. However, during the screening process, a large amount of raw material gets stuck in the holes of the drum screen and is difficult to remove. This not only affects the screening efficiency, but also causes excessive blockage after prolonged operation. As a result, the equipment needs to be stopped, the outer casing of the equipment needs to be disassembled, and the holes of the drum screen needs to be cleaned, which consumes a lot of time. Utility Model Content

[0004] The purpose of this invention is to provide an organic fertilizer raw material processing and screening equipment. By setting up a collision mechanism, specifically, during the rotation of the drum screen, the arc-shaped push block contacts and pushes the arc-shaped protrusion. At this time, the movable rod is pushed and the spring is squeezed. When the arc-shaped push block disengages from the arc-shaped protrusion, the arc-shaped protrusion will quickly rebound and reset by the spring and collide with the drum screen, causing the drum screen to vibrate. This can vibrate and dislodge particles stuck in the screen holes, avoiding clogging of the drum screen. At the same time, it eliminates the need for frequent cleaning of the drum screen holes by workers. This solves the problem that traditional organic fertilizer raw material processing and screening usually uses drum screens, but during the screening process, a large amount of raw material gets stuck in the holes of the drum screen and is difficult to remove.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an organic fertilizer raw material processing and screening equipment, comprising a base, a screening box fixedly connected to the top of the base, a collection box positioned at the bottom of the base, a feed hopper fixedly connected to the left side of the screening box, and a drum screen installed inside the screening box, and further comprising:

[0007] A collision mechanism is provided at the bottom of the drum screen to generate vibration in the drum screen. The collision mechanism includes a movable rod located below the drum screen, a fixed rod rotatably connected to the bottom of the movable rod, an arc-shaped protrusion fixedly connected to the side of the movable rod facing the drum screen, a spring fixedly connected to the bottom of the movable rod, and several arc-shaped push blocks fixedly connected to the outer surface of the drum screen. The movable rod and the arc-shaped protrusion are integrally formed, and the spring supports the movable rod and applies elastic force to it.

[0008] The drum screen has a partition at the center of its outer side, and the outer side of the partition is fixedly connected to the inner wall of the screening box. The drum screen on the left side of the partition has small sieve holes, and the drum screen on the right side of the partition has large sieve holes.

The turning rods are connected to the fixing strips by welding and are used to loosen and disperse the accumulated fertilizer.

[0016] Furthermore, the drum screen is tilted, with the left side of the drum screen higher than the right side, and the tilt angle is ten degrees. The fixing frame and the connecting shaft are connected to transmit power.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model incorporates a collision mechanism. Specifically, during the rotation of the drum screen, the arc-shaped push block contacts and pushes the arc-shaped protrusion. At this time, the movable rod is pushed and the spring is squeezed. When the arc-shaped push block disengages from the arc-shaped protrusion, the arc-shaped protrusion will quickly rebound and reset through the spring, colliding with the drum screen. This causes the drum screen to vibrate, which can dislodge particles stuck in the screen holes, preventing the drum screen from becoming clogged. At the same time, it eliminates the need for frequent cleaning of the screen holes by the staff.

[0019] 2. This utility model features a flipping rod. Specifically, when the drum screen rotates, the internal fixing bars and the flipping rod rotate together. The flipping rod then turns and spreads the fertilizer, improving the screening effect and reducing accumulation. The drum screen is also set with the left side higher than the right side and a low tilt, allowing the fertilizer to move slowly to the right, thus preventing residue from remaining inside the drum screen after screening.

During the rotation of the drum screen 13, the arc-shaped push blocks 136 contact the arc-shaped protrusion 23 and push it. At this time, the movable rod 21 is pushed and the spring 24 is released. When the spring 24 is pressed, after the arc-shaped push block 136 disengages from the arc-shaped protrusion 23, the arc-shaped protrusion 23 will quickly rebound and reset through the spring 24 and collide with the drum screen 13, causing the drum screen 13 to vibrate. This can vibrate and dislodge the particles stuck in the screen holes, preventing the drum screen 13 from becoming clogged. At the same time, it eliminates the need for frequent cleaning of the screen holes of the drum screen 13 by the staff. A partition 133 is set at the center of the outer side of the drum screen 13. The outer side of the partition 133 is fixedly connected to the inner wall of the screening box 11. Small screen holes are opened on the drum screen 13 on the left side of the partition 133, and large screen holes are opened on the drum screen 13 on the right side of the partition 133.

[0032] A support plate 131 is rotatably connected to the inner wall of the left side of the drum screen 13. The left side of the support plate 131 is fixedly connected to the inner wall of the screening box 11 via a connecting shaft. A fixing frame 132 is fixedly connected to the right side of the inner wall of the drum screen 13. A guide ring 134 is sleeved on the outer side of the right side of the drum screen 13. The outer side of the guide ring 134 is fixedly connected to the inner wall of the screening box 11. The support plate 131, the partition 133, and the guide ring 134 all support the drum screen 13. The bottom of the feed hopper 111 passes through the screening box 11 and the support plate 131 and extends into the drum screen 13.

[0033] The inner wall of the screening box 11 is fixedly connected to both the front and back of the guide plate 135. The two guide plates 135 form a V-shape. The collection box 12 is directly opposite the bottom of the guide plate 135. The right side of the fixing frame 132 is fixedly connected to the connecting shaft 137. The connecting shaft 137 passes through the right side of the screening box 11 and extends to the outside. The connecting shaft 137 is rotatably connected to the screening box 11. The guide plate 135 is used to guide the fertilizer after screening. The guide ring 134 is used to close the right side of the drum screen 13.

[0034] The fixed rod 22 is fixedly connected to the surface of the partition 133 on the side facing the partition 133, the bottom of the spring 24 is fixedly connected to the inner wall of the front guide plate 135, and the arc-shaped protrusion 23 and the arc-shaped push block 136 are both arc-shaped on the side that are close to each other.

[0035] A drive mechanism 14 is provided on the right side of the base 1. The drive mechanism 14 includes a motor, a small belt pulley and a large belt pulley. The small belt pulley is fixedly connected to the output end of the motor. The large belt pulley is fixedly connected to the right side of the connecting shaft 137. The small belt pulley and the large belt pulley are connected by belt drive. A discharge port 15 is provided on the right side of the base 1.

[0036] Several fixing bars 3 are fixedly connected to the inner wall of the drum screen 13, and several flipping rods 31 are fixedly connected to the outer surface of the fixing bars 3. The flipping rods 31 are used to turn the fertilizer inside the drum screen 13. The drum screen 13 is set at an inclination, with the left side of the drum screen 13 being higher than the right side, and the inclination angle is 10 degrees. The fixing frame 132 and the connecting shaft 137 are connected to transmit power. When the drum screen 13 rotates, the fixing bars 3 and the flipping rods 31 inside will rotate together. The flipping rods 31 will turn and scatter the fertilizer, improve the screening effect of the fertilizer, and reduce the accumulation. The drum screen 13 is set at a left-high and right-low angle with a low inclination, so that the fertilizer can move slowly to the right and avoid the residue in the drum screen 13 after screening.

[0037] One specific application of this embodiment is:

[0038] In use, the drive mechanism 14 is activated, which drives the pulley to rotate via the motor. The pulley then drives the drum screen 13 to rotate via the connecting shaft 137. At this time, the left side of the drum screen 13 rotates on the support plate 131, and the right side rotates within the guide ring 134. Fertilizer to be screened is then fed into the feed hopper 111 and conveyed into the drum screen 13. The drum screen 13 has two sizes of screen holes to screen the fertilizer. The screened fertilizer is discharged from the drum screen 13 and guided by the guide plate 135 into two collection boxes 12 for collection. The partition 133 separates the two different sizes of fertilizer, ensuring that they are collected separately. The drum screen 13 is positioned with a left-high, right-low tilt, allowing the fertilizer to move slowly to the right. Larger particles are discharged from the right side of the drum screen 13 and guided by the guide ring 134 to be discharged from the discharge port 15. During the rotation of the drum screen 13, the arc-shaped push block 136 rotates along with it. When it comes into contact with the arc-shaped protrusion 23 on the movable rod 21, it pushes the arc-shaped protrusion 23. At this time, the movable rod 21 is pushed, and the bottom of the movable rod 21 rotates on the fixed rod 22. At the same time, the spring 24 is compressed. When the arc-shaped push block 136 disengages from the arc-shaped protrusion 23, the movable rod 21 and the arc-shaped protrusion 23 will quickly rebound and reset under the elastic action of the spring 24. At this time, the arc-shaped protrusion 23 will collide with the drum screen 13, thereby causing the drum screen 13 to vibrate. This can vibrate and dislodge the particles stuck in the screen holes, preventing the drum screen 13 from becoming clogged. At the same time, it does not require the staff to frequently clean the screen holes of the drum screen 13. Furthermore, when the drum screen 13 rotates, the internal fixed bar 3 and the flipping rod 31 will rotate along with it. The flipping rod 31 will turn and spread the fertilizer, improving the fertilizer screening effect and reducing the accumulation of fertilizer.
