Description
Technical Field
The invention relates to the field of excavators, in particular to a cutting pick used on an excavator.
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, particularly 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 dig pick that machine used, it includes that columniform handle of a knife and columniform tool bit body constitute, the front end post head center department of tool bit body is equipped with the semicircular deep hole that is of an indent to be equipped with an annular alloy groove around the deep hole, this alloy inslot is equipped with a plurality of evenly distributed's circular aperture, and it has vertical bar form carbide piece to inlay in the aperture, the outside of carbide piece is equipped with the slope form of round and is used for the location limit of location usefulness, the outside of tool bit body is for having one and is used for fixed annular positioning groove, two links of annular positioning groove are equipped with the transition slope of location usefulness respectively, and the bottom of its tool bit 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 cylindrical tool handle is provided with a circular support surface which is connected with the bottom of the tool bit and is turned outwards, the bottom of the cylindrical tool handle is provided with an annular clamping ring groove to form an outer circular plate-shaped bottom seat, and a conical slope which is convenient for positioning and is used for transition is arranged on the bottom seat.
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 8 and are arranged in the circular small holes in the alloy grooves in a pairwise opposite mode.
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: the utility model provides a dig pick that machine used, it includes that columniform handle of a knife 1 and columniform tool bit body 2 constitute, the front end post head center department of tool bit body 2 is equipped with the semicircular deep hole 3 that is of an indent to be equipped with an annular alloy groove 4 around deep hole 3, be equipped with a plurality of evenly distributed's circular aperture 5 in this alloy groove 4, and it has vertical bar form carbide piece 6 to inlay in the aperture, the outside of carbide piece 6 is equipped with the round and is the slope form be used for location limit 7 of usefulness, the outside of tool bit body 2 is for having one to be used for fixed annular positioning groove 8, the two links of annular positioning groove 8 are equipped with the transition slope 9 of location usefulness respectively, and the bottom of its tool bit 2 also is equipped with the transition slope 10 that is used for the location, the diameter of tool bit body 2 is greater than the diameter of handle of a knife 1.
As shown in the figure: the tool is characterized in that a circular supporting surface 11 which is connected with the bottom of the tool bit and is outwards turned out is arranged at the top 1 end of the cylindrical tool handle, an annular clamping ring groove 12 is arranged at the bottom of the cylindrical tool handle 1, an outer circular plate-shaped bottom seat 13 is formed, and a conical slope 14 which is convenient to position and is used for transition is arranged on the bottom seat 13.
As shown in fig. 2: two sides of the top of the hard alloy block 6 are respectively provided with a semicircular slope surface 15, an inward concave working groove 16 is arranged between the two semicircular slope surfaces, and the hard alloy blocks are at least 8 and are arranged in the circular small holes 5 in the alloy grooves in a pairwise opposite mode.
The cylindrical hard alloy is uniformly distributed at the front end taper angle head part of the tool bit body, and because the cylindrical hard alloy is deeply embedded into the corresponding deep hole at the taper angle head part and is firmly welded, the welding firmness is greatly improved, the wear resistance of the product is increased, and the service life of the product is prolonged; 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, increased area of contact and let the pick not fragile, also let the tool holder at tool bit during operation rear can be protected, it gets into the rear to keep off fine and small powder, this has also improved the wearability of product greatly, improve the life of product equally.
