[0021] In actual application of this embodiment, when the device is used to crush and grind chemical raw materials, the feed hopper 205 at one end of the grinding cylinder 201 is used to input the chemical raw materials to be processed. Since the bottom of the grinding cylinder 201 is provided with a discharge pipe 203, and the outer wall side of the discharge pipe 203 is provided with an outer ring groove 204, the lifting plate 301 is fixedly mounted on the outer ring groove 204, and the lifting plate 301 is elastically slidably assembled on a plurality of limit rods 102. Therefore, when the device is in the crushing and grinding operation, the greater the mass of the raw materials in the grinding cylinder 201, the greater the displacement of the lifting plate 301 in the first direction x, that is, the lifting plate 301 and the bottom plate 101 are fixedly mounted on the outer ring groove 204. The closer the distance between them is, and during the grinding process, the first transmission shaft 302 always keeps rotating under the action of the driving source. Since the second transmission shaft 303 is slidably inserted on the first transmission shaft 302, the second transmission shaft 303 can be transmitted to the side of the grinding shaft body 305 while following the rotation of the first transmission shaft 302, so that the grinding shaft body 305 rotates along with the second transmission shaft 303. A grinder 306 is fixedly provided at the bottom of the grinding shaft body 305, and the grinder 306 is rotatably sleeved on the guide rod 104. Therefore, during the rotation of the grinder 306, a relative rotation is formed between the grinder 306 and the grinding wall 202, and enters the grinding cylinder. The material in the inner cavity of 201 continuously flows to the gap between the grinding wall 202 and the grinder 306 under the action of gravity. The raw material is continuously ground in the gap through the continuous friction between the grinding wall 202 and the grinder 306, so that the ground small-sized material can pass through the gap and fall into the discharge pipe 203 and be discharged outward along the discharge pipe 203. In the actual grinding process, when the particle size of the raw material input from one side of the feed hopper 205 is large, the gap between the materials is large, so more air is filled between the materials. Since the volume of the storage space of the grinding cylinder 201 is fixed, the actual mass of the large-sized material is lighter. Therefore, the first transmission shaft 302 and the second transmission shaft can be adjusted to adjust the size of the raw material. The relative sliding distance between the grinding wall 202 and the grinder 306 is adjusted to adjust the spacing between the grinding wall 202 and the grinder 306. When grinding large-particle materials, the gap between the grinding wall 202 and the grinder 306 can be increased to avoid low grinding efficiency or even material jamming caused by too small a gap. When grinding small-particle materials, since the gap between small-particle materials is small, the mass is large under the same volume. The gap between the grinding wall 202 and the grinder 306 can be reduced to achieve finer grinding, avoiding small-particle materials passing directly through the gap and generating useless work, so that the device can automatically adjust the grinding accuracy by inputting the particle size of the raw material, thereby improving the grinding efficiency and effect.

[0022] In one case of this embodiment, the device is limited to grinding raw materials of the same material, and the grinding body is mostly powder, which is not suitable for crushing bulk materials or fluid materials, and will not be described in detail here.

[0023] See also Figure 4 In a preferred embodiment of the present invention, the base member 1 further includes a guide plate 105 , which is fixedly mounted on the bottom plate 101 and disposed close to the discharge pipe 203 for discharging the ground raw materials in the grinding cylinder 201 .

[0024] In actual application of this embodiment, the guide plate 105 is fixedly arranged on the bottom plate 101 and is arranged obliquely through the guide rod 104 , so that the ground material dropped from the discharge pipe 203 can flow out through the guide plate 105 .

[0025] See also Figure 2 In a preferred embodiment of the present invention, the grinding chamber assembly 2 further includes a discharge hopper 206, which is fixedly arranged on one side of the wall of the grinding cylinder 201 and is arranged close to one end of the feed hopper 205, for discharging excess raw materials in the cavity of the grinding cylinder 201.

[0026] In actual application of this embodiment, the discharge hopper 206 is set on one side of the feed hopper 205, so that when raw materials are continuously input into the feed hopper 205, when the raw materials fill the inner cavity of the grinding cylinder 201, the excess raw materials can be discharged through the discharge hopper 206, so that the volume of the inner cavity of the grinding cylinder 201 is fixed, so that the mass size of the materials can be compared under the same volume.

[0027] See also Figure 2 In a preferred embodiment of this embodiment, the grinding assembly 3 also includes a driven wheel 307, a driven wall 308 and a driver 309. The driven wheel 307 is slidably arranged at the bottom of the first transmission shaft 302 and is transmission-connected to the first transmission shaft 302. The driver 309 is fixedly arranged on the base plate 101. One end of the driven wall 308 is rotatably sleeved on the first transmission shaft 302, and the other end of the driven wall 308 is rotatably sleeved on the driver 309. The driven wheel 307 and the driver 309 are transmission-connected, and the other end of the driver 309 is transmission-connected to the guide rod 104.

[0028] In actual application of this embodiment, the driver 309 is fixedly set on the base plate 101, and the driven wall 308 is assembled between the first transmission shaft 302 and the driver 309. The driver 309 can drive the driven wheel 307 to rotate synchronously in the driving state. The driven wheel 307 is slidably mounted on the first transmission shaft 302 and is connected to the first transmission shaft 302 for transmission, so it can synchronously drive the first transmission shaft 302 to rotate. The first transmission shaft 302 and the second transmission shaft 303 are slidably connected, so the synchronous rotation of the second transmission shaft 303 can be driven, so that when the lifting plate 301 is lifted and lowered in the first direction x, the driver 309, the first transmission shaft 302 and the second transmission shaft 303 always maintain a transmission state.

[0029] See also Figure 3 In a preferred embodiment of the present invention, the raw material crushing and grinding device for chemical product production has a relative first grinding surface a1 and a second grinding surface a2, the first grinding surface a1 is arranged on the side of the grinding wall 202 facing the grinding shaft 305, and the second grinding surface a2 is arranged on the side of the grinder 306 facing the grinding wall 202, and the first grinding surface a1 and the second grinding surface a2 are arranged at an interval.

[0030] In actual application of this embodiment, the first grinding surface a1 and the second grinding surface a2 are spaced apart, and the first grinding surface a1 and the second grinding surface a2 are the same curved walls. Therefore, when the second grinding surface a2 is raised or lowered in the first direction x, the distance between the first grinding surface a1 and the second grinding surface a2 can be synchronously adjusted, and the distance value is fixed, so that the particle size of the raw material after grinding tends to a fixed particle size range.

[0031] See also Figure 2 and Figure 5 In a preferred embodiment of the present invention, the raw material crushing and grinding device for chemical product production also includes an adjusting mechanism 4, which includes a first adjusting rack 401, a first transmission gear 402, a second transmission gear 403, a second adjusting rack 404 and an adjusting arm 405. The first adjusting rack 401 is fixedly arranged at one end of the lifting plate 301, the first transmission gear 402 is fixedly arranged on the bottom plate 101, and one end of the first transmission gear 402 is meshed with the first adjusting rack 401, and the other end of the first transmission gear 402 is coaxially fixedly connected to the second transmission gear 403, one end of the second adjusting rack 404 is meshed with the second transmission gear 403, and the other end of the second adjusting rack 404 is fixedly connected to the adjusting arm 405, and the end of the adjusting arm 405 is positioned and sleeved on the second transmission shaft 303.

[0032] In actual application of this embodiment, when the lifting plate 301 is lifted or lowered in the first direction x, the first adjustment rack 401 fixedly connected to one end thereof can synchronously engage and drive the first transmission gear 402 to rotate. Since the second transmission gear 403 is fixedly connected to one end of the first transmission gear 402, the second transmission gear 403 can also engage and drive the second adjustment rack 404 to slide in the first direction x during the synchronous rotation. Since the end of the second adjustment rack 404 is positioned and connected to the second transmission shaft 303 through the adjustment arm 405, the second transmission shaft 303 can be pulled to move on the first transmission shaft 302 through the sliding of the second adjustment rack 404, thereby driving the grinding shaft 305 and the grinder 306 to move in the first direction x.

[0033] In one case in this embodiment, the gear diameter of the first transmission gear 402 is smaller than the gear diameter of the second transmission gear 403. When the movement distance of the lifting plate 301 in the first direction x is m, the movement distance of the second adjustment rack 404 during the engagement process is greater than m, so that the lifting speed of the grinding shaft 305 in the first direction x is greater than the lifting speed of the grinding cylinder 201 in the first direction x.

[0034] The above embodiment of the present invention provides a raw material crushing and grinding device for chemical product production, which is equipped with a liftable grinding cylinder 201 slidingly on the bottom plate 101, and a liftable grinder 306 slidingly provided inside the grinding cylinder 201. The grinding accuracy can be automatically adjusted according to the particle size of the input raw material, thereby improving the grinding efficiency and effect and avoiding ineffective work.
