Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

[0027] Refer to Figures 1-6 。

[0028] In view of the problems mentioned in the above background technology, the embodiments of the present invention provide a raw material screening device for chitin fertilizer to solve the above technical problems. The technical solutions are as follows:

[0029] A raw material screening device for chitin fertilizer includes:

[0030] A workbench 110, a first screening component, a second screening component, a vibration motor 130, and a conveyor belt 160;

[0031] Vertical plates 120 are respectively fixed at the four corner positions on the top of the workbench 110; the function of the vertical plates 120 is to support and fix the positions of the subsequent screening components;

[0032] The first screening component includes a first sieve plate 121 fixed on the four vertical plates 120 and inclined, and a baffle plate 122 fixed on the edge of the first sieve plate 121; the lower end of the inclined first sieve plate 121 is a first discharge port; the baffle plate 122 is fixed on the edge of the first sieve plate 121 to prevent the raw materials from overflowing from the edge of the sieve plate;

[0033] The second screening component includes a screening bin 140, and the screening bin 140 is fixed at the bottom of the first sieve plate 121; the top of the screening bin 140 is an open structure; the bottom plate 141 of the screening bin 140 is inclined, and a second sieve plate 142 is arranged at the lower end of the inclined bottom plate 141; a side door is arranged on the side wall of the screening bin 140;

[0034] The vibration motor 130 is arranged on the screening bin 140;

[0035] The conveyor belt 160 is arranged on the top of the workbench 110 and below the screening bin 140; a guide plate 151 is arranged at the bottom of the bottom plate 141, and the guide plate 151 is inclined near the outside of the second sieve plate 142;

[0036] Among them, the inclination direction of the bottom plate 141 is the same as that of the first sieve plate 121, and the inclination direction of the guide plate 151 is opposite to that of the first sieve plate 121.

[0037] In this embodiment, the conveying direction of the conveyor belt 160 is opposite to the rolling direction of the raw materials on the first sieve plate 121. If the conveying direction of the conveyor belt 160 is the same as the rolling direction of the raw materials on the first sieve plate 121, the larger particle gravel removed by screening and the screened raw materials will be discharged at the same position, which may interfere with normal operations.

[0038] In this embodiment, the aperture of the sieve holes on the first sieve plate 121 is larger than that of the sieve holes on the second sieve plate 142, which is used to distinguish and screen larger particle gravel and raw materials.

[0039] In this embodiment, two symmetrically arranged raw material limiting plates 152 are provided on the material guiding plate 151. The raw material limiting plates 152 limit the moving range of the raw materials on the material guiding plate 151, so that the raw materials can be smoothly introduced onto the conveyor belt 160.

[0040] In this embodiment, the conveyor belt 160 includes a bracket fixed to the top of the workbench 110, a driving wheel and a driven wheel rotatably arranged on the bracket, a belt drivingly connected between the driving wheel and the driven wheel, and a motor for driving the driving wheel.

[0041] The usage method of the raw material screening device for chitin fertilizer provided by the embodiment of the present utility model is as follows:

[0042] 1. Workers pour the raw materials into the first screening component, and the vibration motor 130 works. The raw materials roll down along the first sieve plate 121 under the vibration of the vibration motor 130. Among them, the raw materials pass through the sieve holes on the first sieve plate 121 under the action of gravity and fall into the screening bin 140 of the second screening component, and the larger particle gravel rolls out from the first discharge port of the first sieve plate 121.

[0043] 2. The raw materials falling into the screening bin 140 move downward along the bottom plate 141 of the screening bin 140 under the vibration of the vibration motor 130 and move onto the second sieve plate 142. The raw materials meeting the standard particle size pass through the sieve holes on the second sieve plate 142 under the action of gravity and fall onto the conveyor belt 160. The conveying direction of the conveyor belt 160 is opposite to the rolling direction of the raw materials on the first sieve plate 121. A collection container can be placed at the end of the conveying direction of the conveyor belt 160 to collect the screened raw materials.

[0044] 3. After the screening operation is completed, the raw materials that do not meet the standard particle size remain in the screening bin 140. Open the side door on the side wall of the screening bin 140, and use tools to take out the unqualified large particle raw materials and perform crushing operations again.

[0045] The raw material screening device for chitin fertilizer provided by the embodiment of the present utility model has the following beneficial effects: The present utility model designs a raw material screening device for chitin fertilizer, which can screen out and remove the larger particle gravel mixed in the raw materials and screen out the unqualified large particle raw materials for re-crushing, which is simple and applicable.
