[0002] A pulverizer is a mechanical device used to break solid matter into smaller particles or powders. These machines usually include a rotating blade, hammer or drum that breaks the material by mechanical force or impact. Pulverizers are widely used in fields including waste treatment, food processing, chemical, pharmaceutical, mining and building material processing.

[0003] After searching, Chinese patent announcement number: CN219233051U discloses a crusher with a sorting function. The device can clean the smoke and dust generated by the material falling from the discharge hopper through the cooperation of a vacuum cleaner and a vacuum tube. The protective shell, screen and feed bin are driven to vibrate through the cooperation of a vibration motor and a spring. At this time, the screen can sort the material, and the sorted material falls through the feed bin into the cavities at different positions inside the collection box for collection.

[0004] However, in actual use, since the device only uses a screen to vibrate and sort the material, the device cannot process gypsum powder of different particle sizes through a single sorting, and the material needs to be screened multiple times to obtain gypsum materials of different particle sizes, which makes the processing process more time-consuming and labor-intensive. Therefore, a crusher with a sorting function is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: comprising a machine body 1, a feed port 4 is fixedly connected to the upper end of the machine body 1, a crushing roller 5 is rotatably connected to the inner surface of the machine body 1, a sorting device 2 is arranged on the upper end of the inner surface of the machine body 1, and sorting and collecting devices 3 are arranged on both sides of the left and right sides of the machine body 1;

[0033] The sorting device 2 includes a sieve plate 203, a blocking block 201 is fixedly connected to the upper surface of the sieve plate 203, a fixing block 204 is fixedly connected to the inner surface of the body 1, and dust curtains 202 are fixedly connected to the left and right sides of the body 1. Two groups of sieve plates 203 are provided, and the two groups of sieve plates 203 are fixedly connected by a connecting plate 205.

[0034] The left and right ends of the body 1 are provided with through rectangular through holes, so that the materials that cannot pass through the screen plate 203 can move into the collecting bin 203. The front and rear ends of the body 1 are provided with through holes, so that the crushing roller 5 can be connected to an external driving device. The screen plate 203 is arranged as a whole in an inclined shape, so that the materials falling onto its upper surface can move toward its lower end. The end of the screen plate 203 close to the fixed block 204 is slidably connected to the body 1. The blocking block 201 is arranged in a semicircular arc shape, so that the sliding speed of the materials on the surface of the screen plate 203 can be reduced and it can be fully screened. The upper end of the fixed block 204 is elastically connected to the screen plate 203 through a spring, so that when the screen plate 203 is squeezed by the material discharged from the upper part, it can squeeze the spring to vibrate. There are multiple groups of dust curtains 202, and the spacing distances between the multiple groups of dust curtains 202 are the same, so the dust emission during the material crushing process can be reduced. The two groups of screen plates 203 are inclined in opposite directions and have the same inclination angle.

[0035] Reference Figure 1 as well as Figure 4 The sorting and collecting device 3 includes a supporting block 301 , a collecting bin 303 is fixedly connected to the lower end of the supporting block 301 , and an inserting rod 302 is fixedly connected to both the left and right ends of the body 1 .

[0036] A through hole is provided at the center of the inner surface of the support block 301, so that the insertion rod 302 can be inserted into the support block 301 from here, and a rectangular through hole is provided above the through hole on the inner surface of the support block 301, so that the insertion rod 302 cannot be directly taken out when it moves to this point, and a rectangular groove is provided at one end of the collection bin 303 close to the screen plate 203, so that during the installation process, there will be no movement interference between the collection bin 303 and the screen plate 203, and the diameter of the insertion rod 302 at one end close to the body 1 is smaller than that at the end away from the body 1.

[0037] Working principle: When the device is used, the gypsum material to be crushed needs to be put into the feed port 4, and the crushing roller 5 is driven to rotate by an external driving device, and the gypsum material is crushed by the crushing roller 5. At the same time, the crushed gypsum powder will fall onto the upper surface of the sieve plate 203, and then press the sieve plate 203 downward to squeeze the spring below and vibrate. At the same time, the material will also move downward along the inclined sieve plate 203 during the vibration process and be sorted. The material passing through the upper sieve plate 203 will fall downward to the lower sieve plate 203, thereby being screened multiple times, and the material that has passed the multiple screenings will be classified and stored according to its particle size.

[0038] At the same time, when the collected gypsum powder needs to be taken out, the collection bin 303 needs to be lifted up as a whole, and the cylindrical protrusion of the insertion rod 302 can be aligned with the through hole at the center of the inner surface of the support block 301. At this time, the collection bin 303 can be easily removed, and the materials inside it can be taken out for classification and processing.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
