Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution: a straw impurity removal tool, including a main structure 1, which includes a base 101 and a shell 103. The shell 103 is fixedly connected to the inner surface of the base 101. A filter structure 5 is rotatably connected inside the shell 103. The filter structure 5 includes a filter roller 502 and mesh 503. The filter roller 502 is rotatably connected inside the shell 103. Several mesh 503 are opened through the side surface of the filter roller 502. A feed pipe 501 is fixedly connected through one side surface inside the shell 103. A feed hopper 104 is fixedly installed at the upper end of the feed pipe 501. A discharge hopper 504 is fixedly connected through the lower end inside the shell 103. A drive is installed at the upper end of one side of the base 101. The driving structure 2 includes a mounting base 201 and a drive motor 202. The drive motor 202 is fixedly mounted on the upper side surface of the base 101 via the mounting base 201. The filter drum 502 is connected to the output end of the drive motor 202. A crushing structure 6 is installed inside the filter drum 502. The crushing structure 6 includes a collision plate 601 and an elastic plate 603. The elastic plate 603 is fixedly mounted on the inner side wall surface of the filter drum 502 via a fixed shaft 602. Several elastic plates 603 are provided. The collision plate 601 is fixedly mounted on the side surface of the feed pipe 501. Through the crushing structure 6, when removing impurities from the straw, the straw is fed into the interior of the filter drum 502 through the feed pipe 501. When the mesh 503 of filter roller 502 removes impurities from the straw, the rotation of filter roller 502 simultaneously drives the inner fixed shaft 602 and elastic plate 603 to rotate. When the elastic plate 603 collides with the collision block, it is squeezed and deformed by the collision block. When it leaves the collision block, the elastic plate 603 returns to its original shape. At the same time, the straw inside filter roller 502 is ejected and collided with the inner surface of filter roller 502. The straw is broken up through the collision between the inner wall of filter roller 502 and the straw, thus achieving the purpose of removing impurities and breaking up the straw at the same time. This reduces the straw processing cost and accelerates the processing efficiency of straw. It effectively avoids the need for additional breaking processes to ensure the purity of straw materials and improve their utilization efficiency. The straw is processed by crushing or pulverizing equipment, and then undergoes a secondary processing through an impurity removal device to meet specific application requirements. While this method achieves the goal, it undoubtedly increases the complexity of operation and production costs, and also reduces processing efficiency. Through the filter structure 5 and the discharge structure 3, when the straw enters the outer shell 103 for impurity removal, the drive motor 202 rotates the filter drum 502. Straw particles of standard size pass through the mesh 503 and enter the space between the outer shell 103 and the filter drum 502, and are discharged through the discharge hopper 504. After being conveyed by the conveying structure 4, it is discharged through the discharge structure 3. Simultaneously, the elastic force of the spring structure 304...When the straw is guided by the guide plate 302, it acts as a buffer, preventing the straw from forming excessively small particles due to violent collisions during the discharge process, which would otherwise lead to uneven dispersion of the straw in the applied material.

[0023] In this invention, preferably, a conveying structure 4 is installed on the lower inner surface of the base 101. The conveying structure 4 includes a conveyor belt 402 and a drive shaft 401. The drive shaft 401 and the output end of the drive motor 202 are connected to each other via a drive belt 403. Two drive shafts 401 are provided, and the two drive shafts 401 are connected to each other via the conveyor belt 402. Support legs 102 are fixedly connected to the four corners of the lower surface of the base 101. Four support legs 102 are provided. A discharge structure 3 is installed at one end of the base 101. The discharge structure 3 includes a guide plate 302 and a spring structure 304. The guide plate 302 is rotatably connected to one end of the base 101 via a rotating shaft 301. A spring structure 304 is provided between the guide plate 302 and the support leg 102. Baffles 303 are fixedly connected to both ends of the upper surface of the guide plate 302. Tempered glass 7 is installed on the outer surface of the filter roller 502. A control panel 105 is installed at the lower end of one side surface of the base 101. The drive motor 202 is electrically connected to an external power supply through the control panel 105.

[0024] The working principle and usage process of this utility model are as follows: First, straw is fed into the hopper 104, allowing it to enter the filter drum 502 inside the outer shell 103 through the feed pipe 501. Then, the drive motor 202 is started, and the drive structure 2 drives the filter drum 502 to rotate. The side surface of the filter drum 502 is provided with multiple mesh holes 503 to remove impurities from the straw inside. During this process, the crushing structure 6 inside the filter drum 502 crushes the impurities in the straw. This crushing structure 6 consists of a collision plate 601 and an elastic plate 603. The elastic plate 603 is installed on the inner wall of the filter drum 502 via a fixed shaft 602. When the elastic plate 603 collides with the collision plate 601, it deforms, then returns to its original shape, ejecting the straw back to the inner wall of the filter drum 502, thus achieving crushing. The crushed straw particles pass through the mesh holes 503 and enter the space between the outer shell 103 and the filter drum 502. The base 101 has a conveying structure 4 on its lower internal surface, including a conveyor belt 402 and a drive shaft 401. The drive shaft 401 is connected to the output end of the drive motor 202 via a drive belt 403, allowing the straw particles to be conveyed by the conveyor belt 402 and finally discharged from the discharge hopper 504. The discharge structure 3 at one end of the base 101 includes a guide plate 302 and a spring structure 304. The guide plate 302 is connected to the base 101 via a rotating shaft 301. The spring structure 304 is located between the guide plate 302 and the support leg 102 to buffer the impact of the straw during discharge and prevent uneven distribution caused by excessively fine particles. The control panel 105 is installed on the lower end of one side surface of the base 101 and connects the drive motor 202 to an external power supply. The control panel 105 can control the drive motor 202, thereby controlling the rotation of the filter drum 502. The straw is crushed while removing impurities, which reduces processing costs and improves processing efficiency.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
