Abstract
The utility model relates to a modular pick, but the part is changed, save material, for realizing above-mentioned purpose, the utility model provides a following technical scheme: a combined cutting pick is characterized in that: including the tool bit and the body of rod, the tool bit includes the tool bit top and the tool bit bottom of components of a whole that can function independently, the tool bit top can be dismantled with the body of rod respectively with the tool bit bottom and be connected.
Description
Technical Field
The utility model relates to an excavating equipment field, concretely relates to modular pick.
Background
Apparatus for mining or excavating in hard ground includes a rotary tool in which a plurality of protruding picks are mounted for engagement with the ground. The picks bite into the ground as they rotate with the drum, impacting the earth and removing or breaking up the earth from the surface.
Because the pick needs direct and ground contact, the frictional force that receives is very big, under the condition of permanent work, very easily receives wearing and tearing, and the pick after the damage can become dull, is difficult to insert the ground fast in, causes work efficiency low, the energy increase of machine consumption. And the tool bit on the pick can not be changed after wearing and tearing, need change whole pick and just can guarantee the normal operating mass of machine, and the degree of wear of tool bit top and tool bit side is also different simultaneously, if the whole replacement cost is higher.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, provide a modular pick, but partial change save material.
In order to achieve the above purpose, the utility model provides a following technical scheme: a combined cutting pick is characterized in that: including the tool bit and the body of rod, the tool bit includes the tool bit top and the tool bit bottom of components of a whole that can function independently, the tool bit top can be dismantled with the body of rod respectively with the tool bit bottom and be connected.
The utility model discloses further setting is: the utility model discloses a screw thread cutting machine, including body of rod, tool bit, mounting hole cover, pole body top, pole body.
The utility model discloses further setting is: a limiting hole is formed in the portion, penetrating through the bottom of the cutter head to the top of the cutter head, a limiting column is arranged in the limiting hole and is fixedly connected with a limiting table.
The utility model has the characteristics as above: the split structure of tool bit top and tool bit bottom, well core rod and tool bit top screw hole cooperation are connected fixed tool bit top, tool bit top and spacing fixed tool bit bottom, and spacing post prevents that tool bit top and tool bit bottom from taking place to rotate simultaneously, and it is convenient to dismantle, and selectable more tool bit top and tool bit bottom save material reduce cost.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
A combined cutting pick as shown in fig. 1, which is characterized in that: the tool bit comprises a tool bit and a rod body 1, wherein the tool bit comprises a tool bit top part 2 and a tool bit bottom part 3 which are separated, the tool bit top part 2 and the tool bit bottom part 3 are respectively detachably connected with the rod body 1, one end of the rod body 1 is surrounded with a limiting platform 4, the tool bit bottom part 3 is axially penetrated and provided with a mounting hole 5, the tool bit bottom part 3 is sleeved on the rod body 1 through the mounting hole 5 and is abutted against the limiting platform 4, a threaded hole 6 is axially arranged below the tool bit top part 2, a through hole 7 is axially penetrated through the rod body 1, a matched central rod 8 is arranged in the through hole 7, one end of the central rod 8 is provided with a thread matched with the threaded hole 6, one end of the central rod 8 opposite to the thread is provided with a limiting seat 9 with a diameter larger than that of the rod body 1, the central rod 8 is matched and connected with, and a limiting column 11 is arranged in the limiting hole 10, and the limiting column 11 is fixedly connected with the limiting table 4 in a welding manner.
