[0018] Example 1

[0019] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention proposes a grinding mill for preparing pesticide suspensions, comprising a grinding box 1, an upper grinding seat 3, a feed hopper 201, a lower grinding seat 5, and a scraper 7; a sealing cover 102 is detachably installed on the top of the grinding box 1, and a discharge pipe 101 is provided at the bottom of the grinding box 1; the upper grinding seat 3 is rotatably connected to the sealing cover 102 by a rotating mechanism installed on the top of the sealing cover 102; the feed hopper 201 is located at the input end of the upper grinding seat 3, and the feed end of the feed hopper 201 is located at the top of the sealing cover 102; the lower grinding seat 5... The sand mill 1 is driven to rotate by a drive mechanism installed at the bottom of the sand mill 1. The lower sand mill seat 5 corresponds to the upper sand mill seat 3. Multiple sets of grinding protrusions are provided on the inner wall of the upper sand mill seat 3 and the outer wall of the lower sand mill seat 5. A grinding cavity 301 is formed between the upper sand mill seat 3 and the lower sand mill seat 5. The space of the grinding cavity 301 gradually decreases from top to bottom. An arc-shaped seat 501 is provided at the top of the lower sand mill seat 5 to facilitate the guidance of pesticide suspension raw materials to the bottom of the grinding cavity 301. The scraper 7 is driven to rotate by the drive mechanism and is in contact with the bottom of the sand mill 1.

[0020] Furthermore, two sets of lifting mechanisms are symmetrically installed on the outer wall of the sanding box 1. The lifting mechanisms are hydraulic rods, and two sets of ear seats 203 are symmetrically installed on the sealing cover 102. The output ends of the two sets of lifting mechanisms are respectively connected to the corresponding ear seats 203.

[0021] Furthermore, a rotating tube 2 is provided between the rotating mechanism and the upper grinding seat 3. The upper grinding seat 3 is connected to the upper grinding seat 3. The rotating tube 2 is rotatably connected to the sealing cover 102. The rotating mechanism consists of a stepper motor and two sets of meshing gears. One set of gears is connected to the output end of the stepper motor, and the other set of gears is installed outside the rotating tube 2.

[0022] Furthermore, a support frame 202 is provided at the top of the sealing cover 102, and a feed hopper 201 is installed at the other end of the support frame 202. The bottom end of the feed hopper 201 is inserted into the rotating tube 2 and does not contact the rotating tube 2, so as to avoid the feed hopper 201 interfering with the rotation and grinding of the rotating tube 2 and the upper sand grinding seat 3.

[0023] In this embodiment, the controller activates the drive mechanism to drive the lower grinding seat 5 to rotate clockwise, and simultaneously activates the rotation mechanism to drive the rotating tube 2 to rotate, thereby causing the upper grinding seat 3 to rotate counterclockwise. The pesticide suspension raw material is added along the feed hopper 201 and enters the grinding chamber 301 along the rotating tube 2. The different directions of rotation of the perilla seeds and the upper and lower grinding seats 5, along with the gradual decrease in space of the grinding chamber 301 from top to bottom, allow for gradual and thorough grinding of the pesticide suspension raw material, improving processing efficiency. The ground pesticide... The suspending agent falls into the bottom of the sand mill box 1. When the drive mechanism is started, it can simultaneously drive the scraper 7 to rotate along the bottom of the sand mill box 1, thereby moving the raw material at the bottom of the sand mill box 1 until the raw material is discharged along the discharge pipe 101. The controller starts two sets of lifting mechanisms to make the sealing cover 102 move upward away from the sand mill box 1 until the upper sand mill seat 3 is moved to the top outside of the sand mill box 1, which facilitates the cleaning of the inner wall of the upper sand mill seat 3 and the inside of the sand mill box 1, avoiding waste caused by pesticide suspending agent residue or difficulty in cleaning affecting subsequent use.

[0024] Example 2

[0025] like Figures 2 to 4 As shown, the present invention proposes a grinding machine for preparing pesticide suspensions. Compared with Embodiment 1, the inner wall of the grinding box 1 is equipped with an annular seat 4, and an annular groove is opened on the annular seat 4. Multiple sets of connecting frames 502 are installed on the lower grinding seat 5, and the other end of the connecting frame 502 is slidably connected to the annular groove.

[0026] Furthermore, a rod 503 is installed at the bottom of the lower grinding base 5. The rod 503 is a square rod with an insertion cavity. The rod 503 is detachably connected to the drive mechanism. The drive mechanism includes a rotating rod 6, a clearance groove, and an elastic element 602. A slot 601 is provided on the rotating rod 6, and the rod 503 is inserted into the slot 601. The scraper 7 is installed on the rotating rod 6. The clearance groove is installed on the side wall of the slot 601 and distributed on the rotating rod 6. There are at least two sets of clearance grooves, and the clearance grooves correspond to the insertion holes. The elastic element 602 is installed in the clearance groove. An abutment block 603 is installed at the other end of the elastic element 602. The abutment block 603 is slidably connected to the clearance groove and is inserted into the insertion cavity. The insertion end of the abutment block 603 is an arc-shaped surface to facilitate the insertion or separation of the abutment block 603 from the insertion groove.

[0027] In this embodiment, when the sealing cover 102 is far away from the sanding box 1 to a certain height, it is not only convenient to clean the upper sanding seat 3, but also the staff can lift the connecting frame 502 along the annular seat 4 until the lower sanding seat 5 is taken out from the sanding box 1, so that the lower sanding seat 5 can be cleaned quickly and thoroughly. At the same time, it is convenient to clean the inner wall of the sanding box 1, thus improving the cleaning effect.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
