[0031] Among them, through the setting of the motor 130, the motor 130 can drive the cylinder 260 to rotate, thereby driving the rotating shaft 250 and the grinding head 210 to rotate as a whole, so that the grinding head 210 can rotate and grind the chemical raw materials in the grinding chamber 200;

[0032] Among them, by setting the cylinder 260, the rotating shaft 250 can be raised and lowered in the grinding chamber 200, thereby driving the grinding head 210 to move toward the bottom wall of the grinding chamber 200, so that it cooperates with the rotation of the grinding head 210 to better grind the chemical raw materials at the bottom wall of the grinding chamber 200;

[0033] In actual use, the side of the grinding head 210 cooperates with the side wall of the grinding chamber 200, so that when the grinding head 210 grinds the chemical raw material at the bottom wall of the grinding chamber 200 by lifting and rotating, the chemical raw material and the ground powder can overflow onto the upper end surface of the grinding head 210, so that the chemical raw material cannot be fully ground.

[0034] In order to fully grind the chemical raw materials and powders overflowing onto the upper end surface of the grinding head 210, a truncated cone 270 with a diameter gradually increasing from top to bottom is provided on the upper end wall of the grinding head 210 along its circumference, so that the chemical raw materials overflowing onto the truncated cone 270 can slide into the grinding chamber 200 by gravity when the grinding head 210 rises, so that they can continue to be ground under the action of the lifting and rotating of the grinding head 210, so that the grinding effect of the grinding device is better;

[0035] Among them, through the arrangement of the driving component 230 and the scraping component 220, the driving component 230 can drive the scraping component 220 to rotate and scrape along the round table surface 270, so that the chemical raw materials and powders in the grinding chamber 200 that cannot slide into the round table surface 270 can enter the grinding chamber 200 through scraping and continue to be ground, thereby ensuring the grinding effect of the grinding equipment;

[0036] The cover plate 110 is fixedly connected to the opening position of the grinding chamber 200 by bolts 120 , so that the cover plate 110 can be stably installed at the opening position of the grinding chamber 200 during the grinding of the chemical raw materials.

[0037] Combination Figure 2-Figure 3As shown, in this embodiment, the scraping assembly 220 includes a scraper 300 relatively arranged on the conical surface 270, and an L-shaped mounting plate 310 is provided on the scraper 300; the driving assembly 230 includes a rotating ring 320 rotatably arranged in the grinding chamber 200, and one end of the mounting plate 310 is fixedly connected to the outer wall of the rotating ring 320.

[0038] In actual use of this embodiment, the rotating ring 320 is coaxially installed outside the rotating shaft 250, and the scraper 300 is closely attached to the round table surface 270;

[0039] Among them, through the arrangement of the rotating ring 320, the mounting plate 310 and the scraper 300, the rotating ring 320 can drive the mounting plate 310 to rotate, and then the mounting plate 310 can drive the scraper 300 to rotate, so that the scraper 300 can scrape the chemical raw materials on the round table surface 270;

[0040] One end of the mounting plate 310 is connected to the outer wall of the rotating ring 320 by welding, thereby increasing the connection strength between the rotating ring 320 and the mounting plate 310, so that the rotating ring 320 drives the mounting plate 310 to rotate more stably.

[0041] Combination Figure 2-Figure 3 As shown, in this embodiment, teeth grooves are evenly arranged on the inner side wall of the rotating ring 320 along its circumference, a mounting frame 410 is arranged on the outer sleeve of the rotating shaft 250, the rotating ring 320 is rotatably mounted on the mounting frame 410 through a mounting assembly, the mounting frame 410 is fixedly mounted on the lower side of the cover plate 110 through a plurality of telescopic rods 240, a rotatable sub-gear 360 meshing with the teeth grooves is arranged on the mounting frame 410, and a main gear 400 matching the sub-gear 360 is arranged on the rotating shaft 250.

[0042] In actual use of this embodiment, the rotation shaft 250 rotates to drive the main gear 400 to rotate, and the main gear 400 cooperates with the sub-gear 360, so that the main gear 400 can drive the sub-gear 360 to rotate. Since the sub-gear 360 is meshed with the tooth groove, the sub-gear 360 can drive the rotating ring 320 to rotate;

[0043] The mounting frame 410 is arranged inside the rotating ring 320, and includes two parallel triangular plates 440. The two triangular plates 440 are arranged on the upper and lower side surfaces of the sub-gear 360 opposite to each other. The triangular positions of the two triangular plates 440 are connected by a mounting shaft. The sub-gear 360 is rotatably mounted on the corresponding mounting shaft, so that the sub-gear 360 is rotatably mounted on the mounting frame 410.

[0044] The lower end of the telescopic rod 240 is connected to the corresponding corner of the upper triangular plate 440 by welding, and the upper end is connected to the cover plate 110 by welding, thereby making the mounting frame 410 fixed outside the rotating shaft 250, wherein the connection strength between the telescopic rod 240 and the cover plate 110 is increased by welding connection, so that the mounting frame 410 can be better fixed in the grinding chamber 200.

[0045] Combination Figure 2-Figure 4 As shown, in this embodiment, the mounting assembly includes a plurality of support frames 350, a protrusion 340 is provided at one end of the support frame 350, a sliding groove 330 is opened on the outer wall of the rotating ring 320 along its circumference, and the protrusion 340 extends into the sliding groove 330 and is slidably arranged.

[0046] In actual use of this embodiment, the support frame 350 is L-shaped, and one end of the support frame 350 is connected to the mounting frame 410 by welding, so that the connection strength between the support frame 350 and the mounting frame 410 is increased, and the support frame 350 is fixed on the mounting frame 410 more firmly, so that the rotating ring 320 is better fixed on the mounting frame 410;

[0047] Among them, the other end of the support frame 350 is bent and extends toward the bottom wall of the grinding chamber 200. The bent portion of the support frame 350 is provided with a protrusion 340. Through the setting of the slide groove 330, the protrusion 340 can be inserted into the slide groove 330 and slide in the slide groove 330, thereby allowing the rotating ring 320 to be rotatably installed on the mounting frame 410.

[0048] Combination Figure 2-Figure 4 As shown, in this embodiment, the telescopic rod 240 includes an upper tube 420 fixedly connected to the cover plate 110 and a lower tube 430 fixedly connected to the mounting frame 410, a telescopic cavity 510 is provided in the upper tube 420, the upper end of the lower tube 430 extends into the telescopic cavity 510, a spring 500 is provided in the telescopic cavity 510, and the spring 500 is used to push the lower tube 430 to move downward in the telescopic cavity 510.

[0049] In actual use of this embodiment, the spring 500 is set so that it can push the lower cylinder 430 to extend out of the telescopic chamber 510, so that the scraper 300 abuts against the round table surface 270. Even if the scraper assembly 220 is installed in the telescopic chamber 510, the lifting and lowering of the mounting frame 410 in the grinding chamber 200 is ensured. When the rotating shaft 250 is driven by the cylinder 260 to drive the grinding head 210 to rise, the telescopic rod 240 is retracted due to the compression of the spring 500 and the lower cylinder 430 extending into the telescopic chamber 510, so that the mounting frame 410 and the scraper 300 rise with the grinding head 210, ensuring the lifting and lowering of the scraper 300 in the grinding chamber 200.

[0050] Among them, the rotating shaft 250 is provided with limiting rings located on both sides of the mounting frame 410, and the limiting rings are used to limit the mounting frame 410, so as to better ensure the synchronous lifting and lowering of the telescopic rod 240 and the rotating shaft 250, and prevent the misalignment between the secondary gear 360 and the main gear 400, which causes the device to fail to operate.

[0051] Working principle: When it is necessary to grind chemical raw materials, the cover plate 110 is removed, and the chemical raw materials to be ground are introduced into the grinding chamber 200. The chemical raw materials slide along the inner wall of the grinding chamber 200 into the bottom wall of the grinding chamber 200. The cover plate 110 is installed at the opening of the grinding chamber 200 through the bolts 120. The grinding head 210 is driven down by the cylinder 260 to squeeze the chemical raw materials. The motor 130 is started so that the rotating shaft 250 drives the grinding head 210 to rotate, thereby grinding the chemical raw materials. During the grinding process, the cylinder 26 0 continuously drives the rotating shaft 250 to rise and fall, so that the chemical raw materials attached to the truncated table surface 270 slide into the grinding chamber 200. During the grinding process, the rotating shaft 250 drives the sub-gear 360 to rotate, and then the sub-gear 360 drives the rotating ring 320 to rotate, so that the rotating ring 320 drives the scraper 300 to scrape the truncated table surface 270; when the grinding is completed, the motor 130 stops driving, and the cylinder 260 drives the rotating rod to rise, so that the cover plate 110 is removed from the opening of the grinding chamber 200, and the ground chemical raw materials are taken out.
