もかねている。 To explain the embodiment of this invention in detail based on the drawings, A shows a backhoe equipped with an earth removal device, and the backhoe A is equipped with a crawler-type traveling device 1 at the center of the traveling machine frame 2. Swivel base 3 in the section
A rotating frame 4 is mounted on the upper surface of the base 3 so as to be rotatable left and right, and an excavating device 20 is attached to the front end of the frame 4. The excavation device 20 includes a boom 6, an arm 7, and a bucket 8 which are pivotally connected to each other in order from the rear through a boom support 5 so as to be vertically movable, and hydraulic cylinders 6' and 7 disposed respectively. ′、
The machine is configured to perform backhoe work by driving the machine 8'. In addition, a driver's seat 9 is disposed in the center of the swing frame 4, and an engine section 10 is disposed at the rear. Hydraulic pressure generated by a hydraulic pump in the engine section 10 is supplied to the hydraulic motor and each hydraulic cylinder of the traveling device 1. The backhoe A is driven, and the base end of a support rod 12 that supports the earth removal plate 11 is pivotally connected to the lower part of the rear surface 3-1 of the rotating base so as to be able to move up and down.
A soil removal plate 11 is provided at the tip of the ram 12. Furthermore, in the middle of the support rod 12, there are left and right support rods 1.
A cross beam 13 connecting the 2 and 12' is suspended horizontally, and the working end 14-1 of a hydraulic cylinder 14 for elevating the earth removal plate is pivotally connected to the center of the beam 13, and the cylinder 14 is fixed. The end 14-2 is pivotally connected to the tip of a bracket 15 that protrudes rearward from the upper part of the rear surface 3-1 of the base, and the cylinder 14 allows hydraulic pressure from the engine section 10 to flow into the driving section 9. The information is transmitted to the cylinder 14 through the control valve operation of the rotary frame 4, and is configured to move the soil removal plate 11 up and down. Top edge 1
In order to prevent the frame 4 from being damaged due to a collision between the two parts, a frame protection plate 16 is attached to the lower rear surface of the frame 4 at the position where the upper edge of the earth removal plate 11-1 collides with the upper end of the earth removal plate in a vertically overlapping state. , the same protection plate 16
has a substantially rectangular shape with rear left and right corners cut out diagonally, and the front half 16-1 of the plate is attached to the lower surface of the rear end of the rotating frame 4 with mounting bolts 17. 16-2 protrudes rearward from the rear end of the frame 4, and a balance weight 18 for balancing the rotating frame 4 is mounted on the upper surface of the rear half 16-2. 19, and protects the rear end of the swing frame 4 from a collision with the upper edge 11-1 of the earth removal plate, and also serves as a base for mounting the balance weight 18.
