Technical Field
[0001] The utility model relates to the technical field of mining equipment, and particularly relates to a diamond mining cutter head with an efficient chip removal structure. Background Technique
[0002] The mining cutter head is a crucial tool in the process of mining. It is mainly used for cutting ores to improve the mining efficiency and quality. The mining cutter head is usually made of cemented carbide, and according to different usage scenarios and requirements, there are various types of mining cutter heads, such as diamond cutter heads, tungsten steel cutter heads, etc.
[0003] The utility model patent with the authorization announcement number of CN214741309U discloses an adjustable special mining cutter head. The adjustable special mining cutter head includes a mining cutter head cylinder body. An external fixed outer circle block is arranged outside the upper part of the mining cutter head cylinder body. An internal movable column block is arranged inside the mining cutter head cylinder body. A clamping block clamping groove is arranged outside the movable column block, and a plurality of clamping block clamping grooves are provided. Both ends of the fixed outer circle block are provided with push block movable grooves. A push block is arranged inside the push block movable grooves. One end of the push block movable groove is provided with a push clamping block extending groove. One end of the push block is provided with a push clamping block. Compared with the existing auxiliary devices for mining, the adjustable special mining cutter head is equipped with the design of the push clamping block, the push block and the clamping block clamping groove, which makes the adjustment of the cutter head more convenient during use, and solves the problem that the existing special mining cutter head often increases the working intensity of the staff due to inconvenient adjustment during use.
[0004] Although the adjustable special mining cutter head has the advantage of convenient adjustment, there are still the following problems when the device is in use: Since the cutter head continuously contacts and collides with the ores during work, the wear of the cutter head is often relatively serious. And the cutter head is of an integral structure. After the wear of the cutter head occurs, the whole cutter head needs to be replaced, which not only causes waste of resources but also increases the mining cost. In view of this, we propose a diamond mining cutter head with an efficient chip removal structure. Content of the Utility Model

[0030] In this embodiment, a plurality of positioning grooves 101 are opened at the bottom of the cylinder 10, a plurality of positioning blocks 16 are fixed at the top of the cutter seat 14, and the positioning blocks 16 are inserted and matched with the corresponding positioning grooves 101. The arrangement of the positioning blocks 16 and the positioning grooves 101 increases the connection stability and reliability between the cutter seat 14 and the cylinder 10, and increases the overall structural strength of the cutter head.
[0031] In this embodiment, the cross-sectional shapes of the mounting block 17 and the mounting groove 100 are both triangular, and the sizes of the mounting block 17 and the mounting groove 100 are adapted to each other. The triangular design is conducive to driving the rotation of the cutter seat 14 by the rotation of the cylinder 10, which is conducive to stable transmission.
[0032] In this embodiment, the cutter seat 14, the mounting block 17 and the cutter block 15 are of an integrally formed structure, and the cutter seat 14, the mounting block 17 and the cutter block 15 are all made of diamond material. The integrally formed cutter seat 14, mounting block 17 and cutter block 15 have better connection strength, ensure the service life of the cutter seat 14, mounting block 17 and cutter block 15, and the diamond material improves the mining effect of the cutter seat 14, mounting block 17 and cutter block 15.
[0033] In this embodiment, the cylinder 10 and the connecting seat 11 are of an integrally formed structure, and the overall shapes of the cylinder 10 and the connecting seat 11 are both cylindrical. The integrally formed cylinder 10 and connecting seat 11 have higher structural strength and ensure the connection stability of the cylinder 10 and the connecting seat 11.
[0034] In this embodiment, multiple plate bodies 130 are evenly distributed in a circular shape, and the plate bodies 130 and the disk body 13 are of an integrally formed structure.

[0036] It can be understood that the anti-slip block 12 in this embodiment is a finished product made of rubber material, and the rubber material can increase the friction with the hand, thereby facilitating the operator to hold the tool body 1.
[0037] It should be added that the disk body 13 in this embodiment is tightly welded to the outer wall of the column body 10. The tight welding method ensures the tightness of the connection between the disk body 13 and the column body 10 and the reliable installation of the disk body 13.
[0038] When replacing the worn tool holder 14, the user first uses a screwdriver to remove the multiple connecting bolts 18, and the ends of the connecting bolts 18 will then fall off the fixing holes 170. Subsequently, the user pulls the tool holder 14 downward, and the tool holder 14 will drive the mounting block 17 out of the mounting groove 100, and the positioning block 16 will disengage from the positioning groove 101. The worn tool holder 14 is then disassembled. At this time, the user takes out a new tool holder 14, aligns the positioning block 16 with the positioning groove 101 and inserts it, and the mounting block 17 is inserted into the mounting groove 100 at the same time. Finally, the user tightens the multiple connecting bolts 18, and the ends of the connecting bolts 18 are inserted into the fixing holes 170, and the tool holder 14 is fixed to the column body 10, and the replacement of the tool holder 14 is completed.
