Abstract
The utility model belongs to mining machinery apparatus field, disclose one and open lithosphere pick, the alloy head comprising pick body, cutting pick handle and be connected with pick body, pick body top is the cylindrical-shaped structure with bossing, bottom is provided with boss, and boss connects cutting pick handle; Alloy head is connected with the bossing on pick body top; Boss upper surface is evenly distributed with arc groove, and lower surface is evenly distributed with skewed slot; The utility model structure is simple, practical.
Description
Technical field
The utility model belongs to mining machinery apparatus field, relates to a kind of pick, and particularly one opens lithosphere pick.
Background technology
Usual pick, mainly as cutting element conventional in coal-winning machine, development machine, plays a part outbalance in industrial production particularly digging production; Pick is made up of cutting pick handle, pick body and crown, is mainly divided into two classes: pick-shaped cutter and knife shape cutter teeth; Pick surface is generally shiny surface, little with the frictional force of lithosphere or lithosphere in mining process, can not play the effect strengthening pick digging ability.Simultaneously when carrying out lithosphere digging, pick needs directly to cut hard rock, and pick is easy to damage, and adds cost of production.
Utility model content
The purpose of this utility model be to provide a kind of structure simple, practical open lithosphere pick.
For achieving the above object, the utility model is by the following technical solutions: one opens lithosphere pick, the alloy head comprising pick body, cutting pick handle and be connected with pick body, and pick body top is the cylindrical-shaped structure with bossing, bottom is provided with boss, and boss connects cutting pick handle; Alloy head is connected with the bossing on pick body top; Boss upper surface is evenly distributed with arc groove, and lower surface is evenly distributed with skewed slot.
Be connected with wearing layer outside the bossing on pick body top, wearing layer external surface is provided with the screw thread along pick body axial direction.
The inner chamber matched with alloy head is provided with in the bossing on pick body top.
Cutting pick handle is provided with annular through groove.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, adopt pick body boss upper surface to be evenly distributed with arc groove, lower surface is evenly distributed with the frictional force that skewed slot increases pick body and lithosphere, strengthens the cutting effect of pick.
2, adopt outside the bossing on pick body top and be connected with wearing layer, wearing layer external surface is provided with the screw thread along pick body axial direction, can strengthen the abrasion resistance of pick, increase the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
One opens lithosphere pick, as shown in Figure 1, the alloy head 7 comprising pick body 10, cutting pick handle 2 and be connected with pick body 10, pick body 10 top is the cylindrical-shaped structure with bossing 6, and bottom is provided with boss 4, and boss 4 connects cutting pick handle 2; Alloy head 7 is connected with the bossing 6 on pick body 10 top; Boss 4 upper surface is evenly distributed with arc groove 11, and lower surface is evenly distributed with skewed slot 3; Be connected with wearing layer 9 outside the bossing 6 on pick body top, wearing layer 9 external surface is provided with the screw thread 5 along pick body 10 axial direction; The inner chamber 8 matched with alloy head 7 is provided with in the bossing 6 on pick body top; Cutting pick handle is provided with annular through groove 1.
