Description
Technical Field
The utility model relates to a circular pick head for use on ore deposit machine belongs to pick head technical field.
Background
The cutting pick used by the cutting tool of the coal mining machine and the heading machine mainly comprises a cutting pick body and a cutting pick head, the cutting pick heads on the current market are various, the price is also from hundreds of yuan to thousands of yuan, the cutting pick with low price can be damaged after long use, mainly because of the reason that the alloy on the cutting pick head is less, although the alloy of the expensive cutting pick head is more spread over the whole cutting pick head, the really used place is very less, the alloy at the center of the head is generally not consumed, a plurality of alloys are left nearby, the waste is very great, most of the cutting pick heads are in a sickle shape or a Yuanbao shape, the contact area is larger, and the cutting is not convenient for precise fixed point cutting.
Disclosure of Invention
The to-be-solved technical problem of the utility model lies in, to the above-mentioned defect of prior art, provide a simple structure, simple to operate, it is efficient to polish, reduces a stainless steel grinding device of mechanical loss. The utility model discloses mainly can solve through following technical scheme to above-mentioned problem: the utility model provides a circular tooth head for use on ore deposit machine, it includes that columniform handle of a knife and the integrative constitution of tool bit body of round platform shape, the tool bit face central point of body front end round platform shape puts and is equipped with a deep hole to it has conical stereoplasm alloy head and firm in welding to inlay in the deep hole, the top of stereoplasm alloy head is equipped with triangle-shaped alloy decorative pattern to be the rhombus alloy decorative pattern of indent that is equipped with evenly arranging around tool bit body bottom surface, be equipped with two-layer body decorative pattern of evenly arranging on the round platform shape outer wall face of tool bit body, the body decorative pattern is convex slope form's triangle-shaped, tool bit body and the cylindrical handle of a knife of round platform shape between be formed with the transition toper slope of a location of being convenient for.
Preferably, the method comprises the following steps: the tool comprises a cylindrical tool handle and is characterized in that a layer of cylindrical snap ring with the same length as the cylindrical tool handle is arranged outside the cylindrical tool handle, a positioning groove for positioning is formed in the bottom of the snap ring, a gasket is arranged in the middle of the snap ring, and a positioning groove for positioning is formed in the edge of the bottom of the gasket.
Preferably, the method comprises the following steps: the triangular alloy patterns are composed of at least two adjacent convex-concave triangles, and the sharp corners of each triangle are arranged towards the center of the inner side.
The utility model belongs to the improvement to prior art, it has structural design rationally, and the installation is fixed convenient, and is wear-resisting, fastness is strong, long service life, reduces use cost, improves characteristics such as work efficiency.

Fig. 2 is a schematic view of fig. 1 taken along direction a.
Detailed Description
The invention will be described in detail below with reference to the following figures: as shown in fig. 1-2, a circular tooth head for an ore machine comprises a cylindrical cutter handle 1 and a circular truncated cone-shaped cutter head body 2 which are integrally formed, a deep hole 4 is arranged at the center of a circular truncated cone-shaped cutter head face 3 at the front end of the cutter head body, conical hard alloy heads 5 are embedded in the deep hole 4 and are firmly welded, triangular alloy patterns 6 are arranged at the top of each hard alloy head 5, concave rhombic alloy patterns 7 are uniformly distributed around the outer surface of the bottom of the cutter head body 2, two layers of uniformly distributed body patterns 8 are arranged on the circular truncated cone-shaped outer wall surface of the cutter head body 2, the body patterns 8 are in a convex inclined triangular shape, a transition conical slope 9 convenient for positioning is formed between the circular truncated cone-shaped cutter head body 2 and the cylindrical cutter handle 1, a cylindrical retaining ring 10 with the same length as the cylindrical cutter handle 1 is arranged outside the cylindrical cutter handle, and the bottom of the retaining ring 10 is provided with a positioning groove 11 for positioning, the middle position of the retaining ring 10 is provided with a gasket 12, the edge of the bottom of the gasket 12 is provided with a positioning groove 13 for positioning, the triangular alloy pattern is composed of at least two adjacent convex-concave triangles 14, and the sharp corner 15 of each triangle 14 faces to the center of the inner side.
The invention adopts the design of the circular head, so that fixed-point cutting is very convenient, the head is welded together, the replacement is also very convenient, the alloy head can be replaced without replacing the alloy head seat, the alloy head is composed of the spiral alloy belt head and the middle hard alloy block, the whole alloy head is more wear-resistant, and the circular design can ensure that the place to be polished is more accurate. The bottom is equipped with buckle and transition location handle of a knife, can let the fastening more of toothholder, can not cause the appearance of drawing the scheduling problem, and the design at top is exquisite and durable, and the rate of utilization is very high, and the contact surface is also very wide.
