Abstract

PURPOSE:To obtain a strong supporting structure for an arm supporter by a method in which a bracket for fitting the arm of a front loader is provided to the front side of a safety frame covering a driver seat and the bracket and the tractor frame are connected with an auxiliary frame. CONSTITUTION:A safety frame 2 covering the upside of the driver seat of a tractor is vertically fixed to the tractor frame 3, and a bracket 7 for attaching or detaching a fitting base 27 integrally attached with the arm 6 of a front working machine 5, e.g., loader bucket, etc., and an arm cylinder 26 is provided to the frontal strut 4 of the safety frame 2. On the other hand, a reinforcing frame 8 erectly provided from the tractor frame 3 is integrally rigid-connected with the bracket 7. Thus, the safety frame 2 can be used as a fitting base for the support bracket of the arm and the safety frame and the supporting bracked can reinforce each other.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for an arm that connects a front-cutting machine, etc., to a tractor, in which a safety frame surrounding the driver's seat is also used as a mounting base for a support bracket for the arm. , the safety frame or the support platen) are intended to reinforce each other.

For this reason, the present invention has taken the following technical measures.

That is, the front work equipment (5) is attached to the front support (4) (4), which is fixed to the tractor frame (8) at the base of the safety frame (0) that surrounds the driver's seat (1) of the tractor.
) arm (6) (6) platen) (7
) (7), and 7 reinforcing frames (8) provided integrally with each of these platens F ()) (7). An embodiment of the present invention will be described based on the drawings.

The driver's seat (1) for the operator on board the dockter, the steering wheel (g) opposite to it, and the steering wheel (9).
, the same rear strut (b) 0υ, and the double gate Ink are integrated, and are surrounded by a safety frame. (2) - and opposite receiving plate (B)), which are screwed together to form a t''.Furthermore, the front strut (4) has a horizontal bar (B) facing inward at the lower end. At the same time, the seat plate sakaki at the end is screwed to the side of the 712-meter cylinder case that constitutes the dockter frame (8).

The tractor frame (frame) is constructed by rigidly connecting the above-mentioned frame case (1), the engine 7-frame H-axle bracket (2) on the front side, and the mounting plate (2) on the rear side.

The rear strut (b) is fixed to a rear axle nurse extending from the left and right sides of the rear assembly case.

Screw the bracket (7), which is layered on the lid so that the front side is open, onto the front support [) using a bolt, etc., via the mounting bracket on the back side.The bottom surface of this bracket (7) is - is provided integrally, and the plate (to the receiving plate) facing the board axis is fixed to the support (4).
Lifting arm (・) and hydraulic cylinder mechanism for raising and lowering the arm of a seven-stomach work machine (5) (used as a foot loader in the W example), which is configured to be received and supported by a receiving plate.
〇 Pivotally attach to the proximal board, and connect this board to the above-mentioned butchinara)
(7) Mount K and secure it with a removable pin.

(8) is a reinforcing frame, -m is integrated with the above bracket C by welding, etc., and the other end is an axle bracket).
Support frame installed on the top ■In addition, - is 7V
In the packet of the cylinder loader (li), the wheels are front wheels, - is the rear wheels, and - is the hydraulic lever that controls expansion and contraction of the engine cylinder mechanism, etc.

Based on the above configuration, to attach the tractor (6) to the tractor, ground the packet and attach the arm (6) to the tractor.
Support the board with a stand or the like so that the height of the board (1) is approximately equal to the height of the bracket (1) of the rafter, and move the tractor forward so that the recess of the bracket (1) fits into this board. )) and then connect the two using the bottle (2). The arms (6) are sealed between the left and right sides and are attached to the brackets (γ) (γ) formed on the left and right front struts (4) (4), respectively.

After attaching the arm (6) to the tractor, adjust the hydraulic lever as appropriate.
Loader work is possible with the operation of Bracket (γ)
The arm (6) and the front strut (4) are attached to the front support (4) with a horizontal bar (b) attached to the front support (4), which extends slightly from the side of the tractor. The lifting hydraulic cylinder mechanism can be raised and lowered without any trouble.

The detachment of the foot loader (b) from the tractor is completed by performing the above-mentioned installation procedure. Since this Yamei has the above-mentioned configuration, it has the following technical effects. In other words, there are 7 safety layers that are strongly constructed to protect passengers in the event of an aircraft overturn.
Since the front strut of the tractor supports the 7 pin (butchinara) of the work equipment, there is no need for a special mounting stand on the side of the tractor.In addition, the 111-strong frame connects the bracket and the front part of the tractor frame. ) Rafter front IIIili
Moreover, as the safety 7 frame and the auxiliary frame are integrated through the bracket, the two frames form a mutually reinforcing structure, and the support structure for loads in the front and rear directions is particularly strengthened, making it possible to protect the 74-point operation. Even if the sudden shock of the *kt-take machine falling backwards is applied during work with the machine, it can be reliably absorbed, preventing damage to the arm attachment base and safety frame attachment base.
