Description

Technical Field

[0001] This utility model relates to the field of fertilizer screening technology, and in particular to a screening and impurity removal device for a mixture of soil and fertilizer raw materials. Background Technology

[0002] Screening raw materials before mixing soil and fertilizer is an important step to ensure fertilizer quality, improve fertilizer effectiveness, and protect the healthy growth of crops. Screening can remove oversized or undersized particles, ensuring uniform fertilizer particle size and improving the physical properties and application effect of fertilizer.

[0003] Therefore, an agricultural organic fertilizer raw material impurity removal device, with publication number CN221772889U, is described. The device is placed at the location where crushing is required, and the raw material is placed on a vibrating and dispersing screening frame. A servo motor drives the transmission shaft to rotate reciprocally, causing the vibrating and dispersing screening frame to create a bumpy, vibrating motion to crush and screen the raw material. Smaller particles fall into the crushing transfer chamber, while larger, uncrushable impurities remain on top. A rotating motor drives a striking frame to rotate, crushing the particles entering the crushing transfer chamber. After crushing, the particles fall into a mixing component for collection. A mixing motor drives a stirring frame to mix different granular fertilizers.

[0004] However, relying solely on vibration to crush raw materials results in a relatively slow crushing speed, especially when processing materials with high hardness or large block size. It takes a long time to achieve the desired crushing effect, which reduces production efficiency to some extent and makes it difficult to meet the needs of large-scale production.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4As shown, a soil and fertilizer compound raw material screening and impurity removal device includes a crushing and transfer chamber 1 and a swing frame 8 disposed above the opening of the crushing and transfer chamber 1. Several horizontally arranged and adjustable mounting frames 12 are movably installed inside the swing frame 8. Rolling shafts 11 are rotatably connected inside the mounting frames 12. By adjusting the gap between two adjacent rolling shafts 11, fertilizers of different particle sizes can be screened. A collection trough 6 is fixedly installed on the wide right side of the swing frame 8, and a horizontally arranged U-shaped baffle 2 is rotatably connected to the upper surface of the swing frame 8. When the swing frame 8 is tilted and screening fertilizer, larger fertilizer particles or impurities will slide down between two adjacent rolling shafts 11 into the collection trough 6. The purpose of the U-shaped baffle 2 is to prevent... When the fertilizer is tilted, it slides down from both sides of the swing frame 8. The U-shaped baffle 2 is set near the right wide side of the swing frame 8 on the open side, and a connecting arm 3 is connected to the outer side of the U-shaped baffle 2. A hydraulic rod 4 is fixedly installed through one end of the connecting arm 3 and is perpendicular to the U-shaped baffle 2. A crushing plate 5 for crushing fertilizer and slidingly connected to the inner wall of the U-shaped baffle 2 is fixedly installed at the telescopic end of the hydraulic rod 4. When the collection tank 6 is saturated, the swing frame 8 can be tilted in the opposite direction to allow large pieces of fertilizer and impurities collected in the collection tank 6 to enter the swing frame 8. After the impurities are picked out, the connecting arm 3 is used to swing the crushing plate 5 into the U-shaped baffle 2. Then, the hydraulic rod 4 is extended to allow the crushing plate 5 to descend and crush the large pieces of fertilizer on the swing frame 8 to break them up.

[0024] The top edges of the two wide sides of the swing frame 8 are staggered vertically and parallel. The two ends of the mounting bracket 12 are inserted into the upper surfaces of the two wide sides of the swing frame 8. The upper surfaces of the two wide sides of the swing frame 8 are provided with several positioning holes 13 for inserting into the mounting bracket 12. The left wide side of the swing frame 8 is higher than the right wide side, and a pressure strip 7 for pressing one end of several mounting brackets 12 can be detachably installed on the left wide side of the swing frame 8. The position of the mounting bracket 12 on the swing frame 8 can be adjusted by inserting the mounting bracket 12 into the positioning holes 13 at different positions. The pressure strip 7 is fixed to the left side of the swing frame 8 by bolts, so that one end of the mounting bracket 12 can be pressed down by the pressure strip 7, and the mounting bracket 12 can be completely fixed to the swing frame 8.

[0025] The swing frame 8 is fixedly installed with lifting arms 15 that are inserted into the side of the crushing and transfer chamber 1 on both the front and rear long sides. One of the lifting arms 15 is fixedly installed with a tilting motor 10 for driving the swing frame 8 to tilt. The tilting motor 10 is a commonly used stepper motor. The tilting motor 10 drives the swing frame 8 to tilt and sway left and right. The lifting arm 15 moves up and down in the vertical direction. An electric push rod 9 for driving the movement of the lifting arm 15 is fixedly installed on the crushing and transfer chamber 1. The reciprocating extension and retraction of the electric push rod 9 can push the lifting arm 15 to drive the swing frame 8 in the tilted state to shake up and down, so as to achieve smooth fertilizer screening.

[0026] A rotary motor 14 for driving the U-shaped baffle 2 to rotate is fixedly installed at one end of the left wide side of the swing frame 8. A rotary motor 14 is also fixedly installed on the U-shaped baffle 2, and the rotary motor 14 on the U-shaped baffle 2 is used to drive the connecting arm 3 to swing. The rotary motor 14 on the swing frame 8 drives the U-shaped baffle 2 to rotate horizontally until it is separated from the upper surface of the swing frame 8, which makes it convenient for personnel to adjust the position of the mounting frame 12. The rotary motor 14 on the swing frame 8 drives the connecting arm 3 to drive the crushing plate 5 to rotate and swing away from the U-shaped baffle 2, which makes it convenient for personnel to pick out impurities in the swing frame 8.

[0027] The method of use in this embodiment is as follows: when the crushing plate 5 rotates out of the U-shaped baffle 2, the fertilizer is smashed onto the swing frame 8. The electric push rod 9 is used to reciprocate to push the lifting arm 15 to drive the swing frame 8 in the tilted state to shake up and down, so as to achieve smooth screening of fertilizer. Larger fertilizer or impurities will slide down between two adjacent rolling shafts 11 into the collection tank 6. After screening, the swing frame 8 is tilted in the opposite direction to allow the large pieces of fertilizer and impurities collected in the collection tank 6 to enter the swing frame 8. After the impurities are picked out, the connecting arm 3 is used to swing the crushing plate 5 into the U-shaped baffle 2. Then, the hydraulic rod 4 is extended to make the crushing plate 5 descend and crush the large pieces of fertilizer on the swing frame 8 to break them up.

[0028] The wiring diagrams of the hydraulic rod 4, electric push rod 9, tilting motor 10, and rotating motor 14 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the hydraulic rod 4, electric push rod 9, tilting motor 10, and rotating motor 14 will not be explained in detail.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
