Description
Technical Field
The invention relates to the field of cutting picks on excavators, in particular to a cup-shaped mining cutting pick
Background
The mining cutting tooth is one of the vulnerable parts in coal mining and roadway tunneling machinery, is a main tool for coal falling and breaking, and has the performance that the performance of the cutting tooth directly influences the exertion of the production capacity of the coal mining machinery, the power consumption, the working stability and the service life of other related parts. The existing mining cutting pick mainly comprises a cutting pick body and a hard alloy tool bit, wherein the hard alloy tool bit is embedded in a concave hole at the end part of the cutting pick body and fixedly connected through brazing. The hard alloy tool bit at the head part of the mining cutting pick has a coal mining effect and good wear resistance, so that a certain wear-resistant mining effect can be achieved, and the service life of the cutting pick is prolonged; however, as a mineral cutting pick product, in a specific mining process, the whole cutting pick extends into a coal mine layer, wherein the head hard alloy cutter head plays a forward rotating propelling role, and the whole cutting pick body, especially the front end part of the cutting pick body close to and provided with the hard alloy cutter head, is also subjected to more or less strong friction of the coal mine layer.
Disclosure of Invention
An object of the utility model is to overcome the not enough of prior art existence, and provide a simple structure, reasonable, convenient to use can increase the wearability on product surface, and intensity is big, the fastness is high, can improve product life and availability factor's mining pick.
The purpose of the utility model is accomplished through following technical scheme: the utility model provides a mining pick of cup-shaped, it includes the tool bit and the columniform handle of a knife of round platform shape, the front end platform head center department of tool bit body is equipped with the semicircular deep hole of an indent to the round is equipped with a plurality of evenly distributed's circular aperture around the top deep hole of tool bit body, and it has vertical bar form carbide piece to inlay in the aperture, the outside of carbide piece is equipped with the round and is the slope form be used for the transition limit of location usefulness, and its round platform body middle part also becomes the slope form and arranges and form a cupped tool bit, the tool bit bottom also is equipped with the transition slope that is used for the location usefulness, the diameter of tool bit body is greater than the diameter of handle of a knife.
Preferably, the method comprises the following steps: the top end of the upper part of the cylindrical tool handle is provided with a circular supporting surface which is connected with the bottom of the tool bit and is turned outwards, the lower part of the cylindrical tool handle is provided with an annular clamping ring groove to form an outer circular plate-shaped bottom seat, and the bottom seat is provided with a conical slope which is convenient for positioning and is used for transition.
Preferably, the method comprises the following steps: the two sides of the top of the hard alloy block are respectively provided with a semicircular slope surface, an inwards concave working groove is arranged between the two semicircular slope surfaces, and the hard alloy blocks are at least 5 and are uniformly arranged in the circular small holes in the alloy grooves.
The utility model belongs to an improvement to prior art, have simple structure, reasonable, convenient to use can increase the wearability on product surface, and intensity is big, fastness is high, can improve characteristics such as product life and availability factor.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
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: FIG. 1 shows: a cup-shaped mining cutting pick comprises a circular truncated cone-shaped cutting head body 1 and a cylindrical cutter handle 2, wherein an inwards concave semicircular deep hole 3 is formed in the center of the front end of the cutting head body 1, a plurality of uniformly distributed circular small holes 4 are formed in a circle around the deep hole 3 in the top of the cutting head body, vertical bar-shaped hard alloy blocks 5 are embedded in the small holes 4, a circle of slope-shaped transition edges 6 for positioning are arranged on the outer side of each hard alloy block 5, the middle part 7 of the circular truncated cone body is also obliquely arranged to form a cup-shaped cutting head, a transition slope 8 for positioning is also arranged at the bottom of the cutting head body 1, the diameter of the cutting head body 1 is larger than that of the cutter handle 2, a circular support surface 9 which is connected with the bottom of the cutting head and is outwards turned out is arranged at the top end of the upper part of the cylindrical cutter handle, and an annular clamping ring groove 10 is formed in the lower part of the, and form the bottom base 11 of the round tabular outside, there is a conical slope 12 that facilitates the location and is used for transition on the base of the bottom, both sides of the top of the said hard alloy block have semicircular sloping 13 separately, there is a concave working groove 14 in the middle of its two semicircular sloping, the said hard alloy block is at least 5, arrange in the round aperture 4 in the alloy trough evenly.
The utility model is characterized in that the front cone angle head of the tool bit body is uniformly distributed with the cylindrical hard alloy, and the cylindrical hard alloy is deeply embedded into the corresponding deep hole of the cone angle head and is firmly welded, thereby greatly improving the welding firmness, increasing the wear resistance of the product and prolonging the service life of the product; additionally the utility model discloses still be equipped with the constant head tank on the 2 toper outer walls of tool bit body, the constant head tank sets up on the tool bit, let, tool bit and hou mian blade holder are more fastened, and the diameter of tool bit is greater than the handle of a knife, make the contact surface increase between tool bit and the handle of a knife junction, it lets the pick not fragile to have increased area of contact, the bottom of tool bit is equipped with the shirt rim, the handle of a knife at rear can be protected to this shirt rim also let the tool bit during operation, it gets into the rear to keep off thin garrulous powder, this wearability that has also improved the product greatly, the life of product.
