High-precision grinding disc for grinding limestone

Abstract

The high-precision grinding disc comprises an outer shell, a driving motor and a grinding body, the driving motor is fixedly installed on the rear surface of the outer shell, the grinding body is fixedly installed at the position, located in front of the outer shell, of the output end of the driving motor, and supporting blocks are movably embedded in the two sides of the front portion of the outer shell; a scraping and sweeping piece is fixedly installed on the surface of one side of the supporting block, and a fastener is embedded in the surface of the other side of the supporting block. According to the high-precision grinding disc for limestone grinding, when the outer shell is overturned out of a grinding machine, the driving motor is temporarily started to enable the grinding body to rotate, at the moment, along with overturning of the outer shell, the supporting block loses extrusion of the position before overturning of the outer shell, and therefore the supporting block moves forwards; therefore, scraps on the surface of the grinding body can be scraped off before the grinding body is exposed out of the grinding machine, and the scraps are prevented from falling out.

Description

Technical Field

[0001] This utility model relates to a limestone grinding device, and in particular to a high-precision grinding disc for limestone grinding. Background Technology

[0002] Limestone's main component is calcium carbonate. Lime and limestone are widely used as raw materials in building materials and industry. Limestone can be directly processed into stone or burned into quicklime. When using limestone, it is ground to make it into fine particles.

[0003] When limestone is ground, it is ground by a grinding disc inside the grinding machine. When the high-precision grinding disc is flipped open from inside the grinding machine, the grinding media comes into contact with the limestone during the grinding process, so the surface of the limestone will be covered with debris. The opened grinding disc will carry the debris out, so the debris needs to be cleaned up every time the grinding disc is opened, which is quite troublesome. Utility Model Content

[0004] The main objective of this invention is to provide a high-precision grinding disc for limestone grinding, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-precision grinding disc for limestone grinding includes an outer shell, a drive motor, and a grinding body. The drive motor is fixedly installed on the rear surface of the outer shell, and the grinding body is fixedly installed at the output end of the drive motor and located in front of the outer shell. Support blocks are movably embedded in the front two sides of the outer shell. A scraper is fixedly installed on one side surface of the support block, and a fastener is embedded on the other side surface of the support block.

[0007] More preferably, the inner surfaces of the front two sides of the outer casing are provided with embedding grooves, the upper and lower surfaces of the embedding grooves are provided with rod grooves, a guide rod is fixedly installed inside the rod grooves, and a spring is sleeved on the surface of the guide rod.

[0008] More preferably, the front surface of the support block has an installation groove, the upper and lower surfaces of the rear end of the support block are fixedly installed with sleeve blocks, and the other side surface of the support block has insertion holes near the top and bottom.

[0009] More preferably, the front surface of the scraper blade is provided with bristles, and one side surface of the scraper blade is provided with threaded grooves near the top and bottom.

[0010] More preferably, the scraper blade is embedded in the mounting groove, the rear end of the fastener passes through the insertion hole and is embedded in the threaded groove, and the scraper blade is fixed to the support block by the fastener.

[0011] In a further preferred embodiment, the support block is embedded in the embedding groove, the sleeve block is fitted onto the surface of the guide rod, and the bristles are in contact with the grinding body.

[0012] More preferably, the front end of the spring is fixed to the sleeve block, and the rear end of the spring is fixed to the inner rear surface of the rod groove.

[0013] Compared with the prior art, this utility model proposes a high-precision grinding disc for limestone grinding, which has the following beneficial effects:

[0014] In this invention, by setting up a shell, a support block, a scraper blade, and fasteners to work together, when the shell is flipped out of the grinder, the drive motor is briefly started, causing the grinding body to rotate. At this time, as the shell flips, the support block loses the pressure from the position before the shell flips, causing the support block to move forward until the bristles of the scraper blade on the support block come into contact with the grinding body. In this way, the debris on the surface of the grinding body can be scraped off before the grinding body is exposed from the grinder, preventing the debris from falling out.
