Description
Technical Field
The utility model relates to an excavate the accessory field, concretely relates to split type large-scale 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 cutting pick can not be replaced after being worn, the normal working quality of the machine can be ensured only by replacing the whole cutting pick, and the working cost is high.
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 split type large-scale pick, only need change the tool bit, save the cost.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a large-scale split type pick, includes the tool bit and the body of rod, characterized by the tool bit can be dismantled with the body of rod and be connected, the inserting groove has been seted up to the terminal surface that the tool bit is connected with the body of rod, the body of rod be equipped with the grafting portion of inserting groove adaptation, be equipped with positioner between grafting portion and the inserting groove.
The utility model discloses further setting is: the positioning device comprises a spring, the spring is fixedly connected with a positioning head, the insertion part is transversely provided with a mounting hole, and the spring and the fixing head are arranged in the mounting hole.
The utility model discloses further setting is: the inner wall of the insertion groove is provided with a positioning hole matched with the positioning head, and when the insertion part is matched and connected with the insertion groove, the positioning head is arranged in the positioning hole.
The utility model has the characteristics as above: the tool bit can be dismantled with the body of rod and be connected, when the tool bit wearing and tearing, makes tool bit and body of rod separation through pressing down the location head, and then changes the tool bit, saves the cost, easy operation.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
