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.

[0024] like Figures 1 to 5 As shown, the utility model provides a quantitative feeding device for a crusher, comprising a crushing box 1, the top of which is fixedly connected to a feed hopper 24, one side of which is fixedly connected to a first servo motor 2, the end of an output shaft of the first servo motor 2 is fixedly connected to a crushing knife 3, one side of a lower portion of the crushing box 1 is fixedly connected to a feeding box 4, the top of which is fixedly connected to a second servo motor 5, the end of an output shaft of the second servo motor 5 is fixedly connected to a main shaft 6, the outer side of the main shaft 6 is fixedly connected to a first bevel gear 7, the outer side of the first bevel gear 7 is meshingly connected to a second bevel gear 8, the inner side of the second bevel gear 8 is rotatably connected to an auger 9, the auger 9 can make the raw material descend to prevent the entrance from being blocked, the bottom end of the auger 9 is fixedly connected to an isolation plate 10, a feeding port 11 is provided at the lower portion of the crushing box 1, and a collecting frame 25 is provided below the feeding port 11.

[0025] Specifically, a support frame 12 is fitted on one side of the crushing box 1, and a support base plate 13 is fixedly connected to the bottom end of the support frame 12. There are four support base plates 13, which are convenient for supporting the entire device. A hydraulic rod 14 is fixedly connected to the top end of the support base plate 13, and a support column 15 is fixedly connected to the top end of the support base plate 13. A spring 17 is embedded in the support column 15, and a top rod 16 is slidably connected to the inside of the support column 15.

[0026] Furthermore, a sliding plate 20 is fixedly connected to the inner bottom surface of the crushing box 1 , and the cross section of the sliding plate 20 is triangular, so as to facilitate sliding the crushed raw materials into the lower material box 4 .

[0027] Furthermore, a support seat 18 is fitted on the outer side of the main shaft 6, and a bearing 19 is embedded inside the support seat 18, and the bearing 19 is sleeved on the outer side of the main shaft 6. Under the action of the bearing 19, the friction coefficient between the main shaft 6 and the support seat 18 is reduced, thereby ensuring the rotation accuracy of the main shaft 6 and reducing energy consumption.

[0028] It is worth noting that a push handle 21 is fixedly connected to one side of the support frame 12, and an anti-slip sleeve is provided on the outer side of the push handle 21 to prevent the staff's hands from slipping and facilitate the application of thrust.

[0029] It is worth noting that the bottom end of the supporting base plate 13 is fixedly connected with a brake wheel 22, and there are four brake wheels 22, which are distributed on the four corners of the bottom surface of the supporting base plate 13. Under the action of the brake wheels 22, the entire device can be moved and fixed without manual movement by the staff, and has high practical performance.

[0030] It is worth mentioning that the bottom end of the push rod 16 is fixedly connected to the limit block 23, and the limit block 23 slides inside the support column 15. Under the action of the limit block 23, the internal push rod 16 can be limited to prevent the push rod 16 from being pushed out, and it is also convenient for the spring 17 to apply elastic force to it to make the force uniform.

[0031] Among them, the first servo motor 2, the second servo motor 5 and the hydraulic rod 14 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0032] Working principle and process:

[0033] The staff first puts the raw materials into the crushing box 1 through the feed hopper 24, and the first servo motor 2 drives the internal crushing knife 3 to rotate. Under the action of the internal crushing knife 3, the raw materials are chopped, and the raw materials slide into the discharge box 4 under the action of the sliding plate 20 fixedly connected to the bottom surface of the crushing box 1. Then, the second servo motor 5 drives the main shaft 6 to rotate. Under the action of the bearing 19, the friction coefficient between the main shaft 6 and the support seat 18 is reduced, the rotation accuracy of the main shaft 6 is ensured, and the energy consumption is reduced. The main shaft 6 drives the first bevel gear 7 to rotate. The first bevel gear 7 drives the second bevel gear 8 to rotate, and the second bevel gear 8 drives the internally rotating auger 9 to rotate. The auger 9 can make the raw materials go down to prevent the inlet from being blocked. The auger 9 drives the isolation plate 10 fixedly connected at the bottom to rotate. When the isolation plate 10 does not completely block the discharge port 11, the raw materials flow out through the discharge port 11 to the collecting frame 25 below. Because the rotation speed is constant, the discharge amount of the discharge port 11 can be controlled each time, realizing the quantitative discharge of the crusher, preventing the discharge port from being blocked during the discharge process due to excessive internal raw materials, which is beneficial to crushing. The normal operation of the machine is convenient for the staff to collect the processed raw materials and improve the work efficiency. When the height of the crusher is not good, the hydraulic rod 14 fixedly connected to the top of the support bottom plate 13 can be started to make the hydraulic rod 14 push the crushing box 1 and the unloading box 4 to rise as a whole. Four support columns 15 are fixedly connected to the top of the support bottom plate 13. The spring 17 embedded in the support column 15 will push the push rod 16 to move upward. Under the action of the limit block 23, the internal push rod 16 can be limited to prevent it from being ejected, and it is also convenient for the spring 17 to apply elastic force to it. The force is evenly distributed, so that the device can be supported and fixed, and the different heights of the crusher can be adjusted at will, so that the collection frames 25 of different capacities can be placed at the bottom of the discharge port 11, which increases the practicality of the device. After the crushing is completed, the push handle 21 fixedly connected to one side of the support frame 12 is pushed. The anti-slip sleeve on the outside of the push handle 21 can prevent the staff's hands from slipping, making it easier to apply thrust. The brake wheel 22 fixedly connected to the bottom end of the support base plate 13 can move and fix the device without the need for manual movement by the staff, and has high practical performance.
