[0050] When crushing plastic parts:

[0051] When the staff needs to crush the plastic parts by grinding, the plastic parts are poured into the crushing seat 5, and the electric push rod 12 is driven to make the lifting seat 10 on its movable end move downward on the concave frame 8, so that the grinding hammer 11 on the lower side of the lifting seat 10 is embedded in the crushing seat 5. The shape of the lower side of the grinding hammer 11 just fits the internal shape of the crushing seat 5, so that the plastic parts are pressed between the grinding hammer 11 and the inner surface of the crushing seat 5. At this time, the fan-shaped holes 13 on the left and right sides of the grinding hammer 11 are slidably connected with the rectangular plates 16 through two limit rods 14, and the hammer seats 21 on the lower side of each rectangular plate 16 are at two positions. The lower part of each fan-shaped hole 13 and the lower part of the grinding hammer 11 are in the same horizontal plane, and at this time, the first motor 7 is driven to make the support rod 4 drive the crushing seat 5 to rotate, and then the inner surface of the crushing seat 5 and the grinding hammer 11 cooperate to grind and crush the placed plastic parts, and the multiple grooves 22 on the lower surface of each hammer seat 21 can improve the efficiency of the grinding and crushing work to achieve comprehensive grinding and crushing work, and when the grinding and crushing work is performed, the electric push rod 12 is driven appropriately to make the lifting seat 10 move downward to drive the grinding hammer 11 to further press the plastic parts when grinding the plastic parts, so as to improve the efficiency of grinding and crushing the plastic parts;

[0052] Furthermore, when the staff needs to hammer and crush the plastic parts, they pour the plastic parts into the crushing seat 5, and then drive the electric push rod 12 to make the grinding hammer 11 located on the lower side of the lifting seat 10 on its movable end move downward to the upper position close to the crushing seat 5, and then drive the second motor 25 to make the rotating rod 23 fixedly connected to its output shaft through the coupling rotate, and then the two convex seats 24 located on the rotating rod 23 rotate synchronously, and then the concave seats 17 in contact with them are repeatedly pushed by the two convex seats 24, and then the rectangular plate 16 fixedly connected to each concave seat 17 and the hammer seat 21 fixedly connected thereto move downward synchronously, so as to crush the crushing seat 5. The plastic parts in the seat 5 are repeatedly hammered into powder, and the upward elastic force of the spring 20 on the telescopic rod 19 on the front and rear sides of each rectangular plate 16 provides each rectangular plate 16 to return to its original position upward, so that each concave seat 17 and the convex seat 24 in contact with it are always kept in contact, thereby repeatedly hammering the plastic parts in the crushing seat 5 into powder through the hammer seat 21. When the hammering work is performed, the first motor 7 is driven in time to adjust the rotation angle of the crushing seat 5 on the support rod 4, so as to comprehensively hammer and crush the plastic parts in the crushing seat 5. The plastic parts are crushed in different ways according to the needs of the staff, thereby improving the working diversity of the overall device.

[0053] After the plastic parts are ground or hammered, in order to scrape off the plastic parts powder adhered to the grinding hammer 11 and the lower surface of the hammer seat 21, the handles 31 located on the outer sides of the two semicircular frames 26 are manually grasped to move the two semicircular frames 26 toward the middle and cooperate with each other through the jack located in the middle of the matching seat 29 on the left semicircular frame 26 and the embedded rod 30 located in the middle of the matching seat 29 on the right semicircular frame 26 to form a circular whole. At this time, the upper surfaces of the two scraper seats 33 are attached to the left and right half surfaces of the grinding hammer 11. The left and right positions of the two closed semicircular frames 26 can be adjusted in time according to the fitting conditions, so that The two scraper seats 33 are manually pushed to perform circular motion in the track groove 27 through the matching plates 35 at the bottom thereof. The two track grooves 27 follow the fitting of the two semicircular frames 26 to form a complete circular groove, and then the two scraper seats 33 fit the left and right halves of the grinding hammer 11 to perform circular motion. The sharp surfaces 34 on both sides of each scraper seat 33 are used to scrape off the plastic powder adhered to the surface of the grinding hammer 11, thereby reducing direct contact between manual labor and the plastic powder, ensuring the purity of the plastic powder, and preventing the waste of plastic powder. In addition, the powder adhered to the lower surface of each hammer seat 21 can be scraped off synchronously according to the lower side of each scraper seat 33.
