Phase, traditional pick head are generally directly anchored in rotating disk, and the abrasion replacement cycle is short, and replacement is more frequent, are used more
It is inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of coal mine development machines to dig head adjustment structure, is asked with solving above-mentioned technology
Topic.
The utility model uses following technical scheme to achieve the above object:
A kind of coal mine development machine pick head adjustment structure, comprising: pedestal, lead screw, grip slide, pick head ontology, sliding slot, it is special
Sign is: the grip slide can slide along the chute in the sliding slot on pedestal, and the lead screw is in chassis interior one end
It is rotatablely connected with the lateral wall of grip slide, the rear wall of the lead screw and pedestal is threadedly engaged, and the pick head ontology runs through bottom
The front side plate body of seat is connected and fixed with grip slide.
On that basis of the above technical scheme, the pick head ontology is provided with fixing groove in the one end connecting with grip slide.
On that basis of the above technical scheme, the inside of the grip slide is equipped with block slot, the gear inside the block slot
It is rotatablely connected at the top of block with stud, the stud is threadedly engaged with grip slide, on the bottom and pick head ontology of the block
Fixing groove matches.
On that basis of the above technical scheme, for the pick head ontology when being fully inserted into grip slide, block is located at fixing groove
Surface.
On that basis of the above technical scheme, the depth of the fixing groove be greater than pick head body cross-section diameter ten/
One.
Compared with prior art, the utility model has the advantage that the pick head ontology of the utility model is connect with pedestal
Stability is good, easy for installation；Pick head extension elongation can be adjusted by rotational lead screw, rotational lead screw will be dug after digging head body wear
Head ontology ejects outward, adjusts more convenient.

Specific embodiment
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of coal mine development machine digs head adjustment structure, comprising: pedestal 1, lead screw 2, grip slide 3,
Head ontology 4, sliding slot 5 are dug, the grip slide 35 can slide, the lead screw 2 along the chute in the sliding slot 5 on pedestal 1
It being rotatablely connected in the lateral wall of 1 inside one end of pedestal and grip slide 3, the rear wall of the lead screw 2 and pedestal 1 is threadedly engaged,
The pick head ontology 4 is connected and fixed through the front side plate body of pedestal 1 with grip slide 3.
As shown in Figure 3, Figure 4, the pick head ontology 4 is provided with fixing groove 9, the folder in the one end connecting with grip slide 3
The inside of tight sliding block 3 is equipped with block slot 8, and 7 top of block inside the block slot 8 is rotatablely connected with stud 6, the stud 6
It is threadedly engaged with grip slide 3, the bottom of the block 7 is matched with the fixing groove 9 on pick head ontology 4, the pick head ontology 4
When being fully inserted into grip slide 3, block 7 is located at the surface of fixing groove 9,
The depth of the fixing groove 9 is greater than 1/10th of pick 4 cross-sectional diameter of head ontology.
When the pick head ontology 4 of the utility model is installed, the stud 6 on grip slide 3 is first rotated, moves up block 7, then
One end that pick head ontology 4 is provided with fixing groove 9 is passed through from the through-hole on 1 front side plate body of pedestal, is inserted into grip slide 3, completely
After insertion, block 7 is located at right above the fixing groove 9 of pick head ontology 4, at this point, tightening stud 6, moves down block 7, is stuck in fixation
On slot 9；When digging 4 long-time of head ontology using rear serious wear, lead screw 2 is rotated clockwise, pushes grip slide 3 to pedestal 1
Front side plate body is mobile, and pick head ontology 4 is stretched out from pedestal 1, adjusts more convenient, reduction use cost.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With novel introduction, in the case where not departing from the principles of the present invention and spirit, the change that is carried out to embodiment is repaired
Change, replacement and variant is still fallen within the protection scope of the utility model.
