Description

Technical Field

[0001] The present application relates to the technical field of screening devices, and in particular to a screening device for organic fertilizers. Background Art

[0002] In the prior art, after the organic fertilizer is granulated, it needs to be spread out and cooled. During the cooling process, some organic fertilizer particles will absorb moisture in the air and become stuck together. In order to prevent the stuck fertilizer from mixing into the finished feed and thus reducing the product quality, it is necessary to screen out the stuck fertilizer particles. Traditionally, a linear vibrating screen is used for screening. Fertilizers with qualified particle sizes pass through the linear vibrating screen and fall down, while fertilizers with larger particle sizes after bonding move along the surface of the linear vibrating screen to one end for discharge. However, when facing the accumulated fertilizer, the linear vibrating screen often fails to evenly disperse it within the operating time and reaches the discharge position, thereby causing the fertilizers with qualified particle sizes to be discarded together, resulting in excessive fertilizer loss. Utility Model Content

[0003] The problem to be solved by the present application is that when the existing linear vibrating screen is used to screen the fertilizer by particle size, the accumulated fertilizer is difficult to be evenly dispersed on the screen surface within the movement time, so the fertilizer with a qualified particle size is easily discarded.

[0004] In order to solve the above technical problems, the present application provides a screening device for organic fertilizer, including a frame for serving as a basic support, a screen frame assembly for performing particle size screening operations on organic fertilizer is arranged on the top of the frame, a vibration assembly for providing a power source for screening is provided below the screen frame assembly, and a traction assembly is added to the upper part of the frame, which can adjust the horizontal position of the vibration assembly, thereby changing the travel speed of the fertilizer inside the screen frame assembly.

[0005] Since the screening device of the present application is designed with a screen frame assembly, a vibration assembly and a traction assembly, it is possible to implement the particle size screening operation of the fertilizer through the screen frame assembly and the vibration assembly, and to change the movement speed of the fertilizer by adjusting the position of the screening assembly through the traction assembly, so that fertilizers with qualified particle sizes can be fully screened, thereby solving the problem that when the linear vibrating screen of the prior art is used to screen the fertilizers by particle size, the accumulated fertilizers are difficult to be evenly dispersed on the screen surface within the movement time, so that fertilizers with qualified particle sizes are easily discarded.

[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0014] The present application relates to a screening device for organic fertilizer, such as Figure 1-6 As shown, the screening device includes a frame 3 for serving as a basic support, a screen frame assembly 1 for performing particle size screening operations on organic fertilizers is arranged on the top of the frame 3, and a vibration assembly 2 for providing a power source for screening is provided below the screen frame assembly 1. In order to enable the fertilizer to be evenly dispersed on the upper part of the screen frame assembly 1 for sufficient screening operations, thereby reducing the loss of fertilizers with qualified particle sizes, a traction assembly 4 capable of adjusting the horizontal position of the vibration assembly 2 is added to the upper part of the frame 3, so that the vibration assembly 2 is driven by the traction assembly 4 to be at different positions below the screen frame assembly 1, so that the travel speed of the fertilizer inside the screen frame assembly 1 can be changed, so that the fertilizer has sufficient time to be dispersed on the upper part of the screen frame assembly 1, and thus the fertilizer with qualified particle sizes can pass through the screen frame assembly 1 in a timely and effective manner during the operating time and be collected, thereby reducing the loss of fertilizers with qualified particle sizes.

[0015] The screen frame assembly 1 includes a frame plate 6 and a screen plate 5. There are three frame plates 6, which are surrounded on three sides and open on one side. A plurality of screen plates 5 are arranged inside the frame plate 6 along its length direction. The screen plates 5 are arranged in a stepped manner and gradually lowered, so as to facilitate the rolling of the fertilizer along the surface of the screen plate 5.

[0016] In order to facilitate the collection of fertilizers with qualified particle sizes after screening, a support plate 7 for receiving fertilizers with qualified particle sizes is arranged directly below the screen plate 5. In order to prevent fertilizers with qualified particle sizes and fertilizers with larger particle sizes from being discharged in the same direction, the screen plate 5 is tilted in a manner of high on the left and low on the right, and the support plate 7 is tilted in a manner of low on the left and high on the right, so that fertilizers with qualified particle sizes and fertilizers with larger particle sizes are discharged separately in the reverse direction.

[0017] The vibration assembly 2 includes a vibration motor 13, a bracket 11, a support column 10, and a spring 8. The vibration motor 13 is arranged directly below the screen plate 5. In order to transmit the vibration energy of the vibration motor 13 to the screen plate 5, the vibration motor 13 is connected to the frame plate 6 through the bracket 11. In order to make full use of the vibration energy of the vibration motor 13, support columns 10 for supporting the screen frame are arranged around the upper part of the frame 3, and springs 8 with elastic vibration effect are arranged between the support columns 10, so that the vibration effect of the vibration motor 13 is further amplified by the arrangement of the spring 8.

[0018] The traction assembly 4 includes a traction motor 12, a screw 9, and a roller 14. The screw 9 is arranged along the length direction of the frame 3 and passes through the bracket 11, so that the rotation of the screw 9 is converted into linear movement of the bracket 11. In order to ensure that the bracket 11 can move back and forth smoothly along the length direction of the frame 3, a plurality of rollers 14 that can move along the frame plate 6 are symmetrically arranged on both sides of the bracket 11. A traction motor 12 that can drive the screw 9 to rotate is also arranged on the upper part of the frame 3. The screw 9 is driven to rotate by the traction motor 12, and the screw 9 can drive the bracket 11 to move back and forth along the length direction of the frame 3, thereby changing the position of the vibration motor 13.

[0019] When in use, the fertilizer to be screened is placed inside the screen frame assembly 1, and then the traction motor 12 is started first. The traction motor 12 drives the vibration assembly 2 to move to the far end of the screen frame assembly 1 (i.e., the discharge position of the fertilizer with unqualified particle size) through the screw 9, and then the traction motor 12 is stopped, and the vibration motor 13 is made to work. The vibration motor 13 transmits the vibration source generated by itself to the frame plate 6 through the bracket 11. In combination with the action of the spring 8, the screen plate 5 starts to drive the fertilizer to vibrate. At this moment, since the vibration motor 13 is arranged at the far end, the fertilizer on the upper part of the screen plate 5 moves slowly, so that the fertilizer can be fully dispersed on the upper part of the screen plate 5, and then the fertilizer with qualified particle size quickly passes through the screen plate 5 and falls on the upper part of the bracket 7. That is, it is discharged quickly along the support plate 7. After the fertilizer with qualified particle size is discharged slowly (at this time, it means that the fertilizer with unqualified particle size accounts for a large proportion on the upper part of the screen plate 5), the traction motor 12 starts to rotate in the opposite direction, thereby driving the vibration motor 13 to move to the proximal end of the screen frame assembly 1 (that is, the position where the fertilizer with qualified particle size is discharged). At this time, the fertilizer inside the screen frame starts to move quickly and continues to perform the screening operation. The remaining fertilizer with qualified particle size can continue to pass through the screen plate 5 and fall to the upper part of the support plate 7, while the fertilizer with larger particle size is quickly discharged along the surface of the screen plate 5. Therefore, by adjusting the position of the vibration assembly 2 and the screen frame, the movement speed of the fertilizer with qualified particle size and the fertilizer with unqualified particle size can be reasonably controlled, thereby realizing effective separation of the fertilizer and reducing the loss of fertilizer with qualified particle size.
