Technical Field

[0001] This utility model relates to the technical field of putty powder production, specifically a crushing device for producing interior wall putty powder. Background Technology

[0002] Putty is a base material used for repairing and leveling walls, laying a good foundation for the next step of decoration (painting or wallpapering). Putty is divided into two types: interior wall putty and exterior wall putty.

[0003] A Chinese patent document with publication number CN117943188B discloses a crushing and grinding device and method for processing putty powder. The device includes a support frame, a crushing end shell fixedly connected to the inner side of the support frame, an inlet port fixedly connected to the outer side of the top of the crushing end shell, an output shaft rotatably connected to the axis of the crushing end shell, a discharge port fixedly connected to the bottom surface of the crushing end shell, and a transmission shrink tube slidably connected to the bottom end of the inlet port.

[0004] However, the crushing and grinding device in the above solution has a relatively simple structure and cannot screen the material while grinding, thus failing to guarantee the overall fineness of the putty powder, which affects the actual use effect of the putty powder in the later stage. Therefore, this utility model proposes a crushing device for the production of interior wall putty powder to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a crushing device for the production of interior wall putty powder, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for producing interior wall putty powder, comprising:

[0008] The upper grinding body has an integrally formed feeding pipe on its upper surface, and the feeding pipe is rotatably mounted on a second bracket on the ground.

[0009] The material collection hopper is fixed to the ground by support legs, and the lower grinding body and the upper grinding body are located in the inner cavity of the material collection hopper.

[0010] The screen is fixedly connected to an upper annular seat at the upper port of the hopper via a primary connecting rod, and to a lower annular seat at the lower port of the hopper via a secondary connecting rod. A screen mounting beam is fixedly connected between the upper and lower annular seats, and the screen is fixed between adjacent screen mounting beams.

[0011] Preferably, a driven gear is fixedly installed on the feeding pipe, and the driven gear is driven by a driving structure on the second bracket. The feeding pipe is used to feed raw materials.

[0012] Preferably, a guide hopper is fixedly installed on the support leg, and an anti-airway groove is provided on the guide hopper, through which the support column passes.

[0013] Preferably, the support column is provided with a material leakage groove, the outer wall of the support column is abutted against the inner wall of the lower annular seat, and the upper end of the material leakage groove is located at the upper end of the lower annular seat.

[0014] Preferably, a force-bearing column is integrally formed on the inner wall of the port of the hopper, and the force-bearing column is evenly arranged in a circle around the port of the hopper. A connecting rod is fixedly connected to the upper side of the upper grinding body, and an impact rod is fixedly connected to the outer end of the connecting rod through a connecting spring.

[0015] Preferably, when the upper grinding body rotates and the connecting spring is in the reset state, there is an interference between the force-bearing column and the impact rod, and the outer end of the impact rod is hemispherical.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting up a crushing device for producing interior wall putty powder, which consists of a lower grinding body, an upper grinding body, a hopper and a screen, the putty powder raw materials are ground by the lower grinding body and the upper grinding body, and then the putty powder is screened by the screen, thereby effectively ensuring the fineness of the putty powder and ensuring the later use effect of the putty powder.

[0026] Please see Figures 1-5 The present invention provides the following three preferred embodiments:

[0027] Example 1: A pulverizing device for producing interior wall putty powder includes a lower grinding body 1, an upper grinding body 2, a hopper 3, and a screen 4. The lower grinding body 1 is fixed on a support column 5, and the lower end of the support column 5 is fixed to the ground via a first bracket 6. A feeding pipe 7 is integrally formed on the upper surface of the upper grinding body 2, and the feeding pipe 7 is rotatably mounted on a second bracket 8 on the ground. The hopper 3 is fixed to the ground via a support leg 10. The lower grinding body 1 and the upper grinding body 2 are located inside the cavity of the hopper 3. An upper annular seat 12 is fixedly connected to the upper port of the hopper 3 via a primary connecting rod 11. A lower annular seat 14 is fixedly connected to the lower port of the device via a secondary connecting rod 13. A screen mounting beam 15 is fixedly connected between the upper annular seat 12 and the lower annular seat 14. The screen 4 is fixed between adjacent screen mounting beams 15. By setting up a crushing device for producing interior wall putty powder, which is composed of a lower grinding body 1, an upper grinding body 2, a hopper 3 and a screen 4, the putty powder raw material is ground by the lower grinding body 1 and the upper grinding body 2, and then the putty powder is screened by the screen 4, thereby effectively ensuring the fineness of the putty powder and ensuring the later use effect of the putty powder.

[0028] A driven gear 9 is fixedly installed on the feeding pipe 7. The driven gear 9 is driven by the driving structure on the second bracket 8. The feeding pipe 7 is used to feed raw materials. A guide hopper 16 is fixedly installed on the support leg 10. An anti-airway groove is opened on the guide hopper 16. The support column 5 passes through the anti-airway groove.

[0029] In Example 2, based on Example 1, a material leakage groove 17 is provided on the support column 5. The outer wall of the support column 5 is abutted against the inner wall of the lower annular seat 14. The upper end of the material leakage groove 17 is located at the upper end of the lower annular seat 14, which facilitates the discharge of putty powder with excessive particle size, so that it can be reused.

[0030] In Example 3, based on Example 2, a force-bearing column 18 is integrally formed on the inner wall of the port of the hopper 3. The force-bearing column 18 is evenly arranged in a circle around the port of the hopper 3. A connecting rod 19 is fixedly connected to the upper side of the upper grinding body 2. An impact rod 21 is fixedly connected to the outer end of the connecting rod 19 through a connecting spring 20.

[0031] When the upper grinding body 2 rotates and the connecting spring 20 is in the reset state, there is an interference between the force column 18 and the impact rod 21. The outer end of the impact rod 21 is hemispherical. Through the impact of the impact rod 21 and the force column 18, mechanical vibration is generated so that the putty powder can fall more effectively.
