Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention is equipped with a work shaft elevating device in which a work shaft moves in and out from the lower end of a casing by hydraulic means and a work tool such as a clam bucket at the lower end of the work shaft operates. The present invention relates to an underground matter processing device for performing work such as obstacle removal, crushing, and excavation of the ground by the clam bucket and the like.

(B) Conventional Technique When the work shaft elevating device is simply connected to the tip of the boom by a pin, the clam bucket oscillates, which requires time and effort to move and stop the bucket to a desired position for each work.
Therefore, there has been a demand for an underground material processing apparatus that can quickly move and set the clam bucket to a desired position.

(C) Problems to be solved by the present invention The present invention has been made in view of the problems of the conventional example,
An object of the present invention is to obtain an underground matter processing device that can quickly move a clam bucket to any position in front, back, left and right at the beginning of work.

D) As illustrated in FIG. 1, the present invention provides a work shaft elevating device B in which a work shaft moves in and out from a lower end of a casing 11 by hydraulic means and a work tool 13 at the lower end of the work shaft operates. , A boom A, which is oscillated so as to be able to swing forward and backward, and a catch device C for moving the work shaft lifting device B forward and backward is provided between a side portion of the casing 11 and the boom mounting device A1. is there.

E action When removing obstacles in the ground, attach the work axis lifting device B to the articulated boom A of the boom mounting device A1 and operate the articulated boom A and the catch device C as shown in FIG. The work shaft elevating device B is made substantially upright, and the crumb bucket 13 is attached to the lower end of the work shaft 12. When the hydraulic cylinder 22 of the catch device C is moved back and forth in this state, the clam bucket 13 moves back and forth around the horizontal pin 15. Further, when the hydraulic cylinder 32 of the lateral movement device D shown in detail in FIG. 4 is moved forward and backward, the clam bucket 13 moves left and right around the front-rear direction pin 16. By moving the clam bucket 13 back and forth and left and right, the bucket 13 is placed at a desired position, and the working shaft 12 is appropriately lowered by hydraulic means to operate the clam bucket 13 to grab obstacles such as stone blocks and foundation pieces in the ground. The work shaft 12 is raised, the rotating machine base 1 is rotated, the clam bucket 13 is opened, and the obstacle is discharged. Depending on the position and depth of the obstacle, the position of the clam bucket 13 is changed, and the descending degree of the work shaft 12 is changed to complete the obstacle removing work. After removing the clam bucket 13, the catch device C is contracted. Work axis lifting device B
To the side of the machine base 1 to lie down the articulated boom A. By this operation, the work axis elevating device B can be placed on the ground, and therefore when the pins 15 and 19 are removed, the work axis elevating device B is removed from the boom mounting device A1.

The upper end of the handle shaft 14 at the upper portion is pin-connected and suspended from the boom end 6a by a lateral pin 15 and a front-rear direction pin 16 that coincides with the undulating surface of the articulated boom A, so that it can swing back and forth and left and right. A breaker, a rake shovel, or the like may be connected to the lower end of the work shaft 12 for use. C is the casing
It is a catch device provided on the back of 11 and the front of the rotating machine base 2. The structure of this device will be described in detail with reference to FIGS. The parallel protruding piece 17 on the back of the casing 11 and the rotary machine base 1
The parallel projections 18 on the front part of the are connected to the double links 21 in which two ladder-like links are pin-connected to each other by lateral pins 19 and 20, respectively. 22 is the pin 20 and the front link
A hydraulic cylinder connected to a horizontal pin 23 on the lower surface of the connection frame 21b of 21a. D is a casing 1 provided at the front end of the front link 21a
It is a lateral movement device of 1. Reference numeral 24 denotes a frame having a U-shaped cross section fixed to the front end of the double link 21a, and parallel protrusions 26 and 27 are provided on the inner side surfaces of both flange portions 25 along the edges thereof. Reference numeral 28 denotes a pin support member, and the parallel projection piece 29 and the parallel projection piece 17 are rotatably pin-coupled by a lateral pin 19. Reference numeral 30 denotes a slide plate which is fitted between the parallel protrusions 26 and 27 so as to be movable laterally. As shown in FIG. 4, the back surface of the main body portion 28a of the pin support member 28 abuts and faces the surface. It is pivotally attached by a pin 31 so as to be slightly rotatable between the ridges 27. Reference numeral 32 is a hydraulic cylinder connected to a double clevis 33 provided on the back surface of the slide plate 30 and a double clevis 34 provided on the inner bottom of the form 24.
