Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a transfer handle in a management work machine.

In other words, a support plate fixed to the lower surface of the base of the handle base that connects the handle rod is joined to a handle mounting base fixed to the upper end of the transmission case, and the handle base can be rotated to change the handle in the front-rear direction of the aircraft. In the control work machine configured to allow the handle base to be easily assembled and fixed by welding so that the support plate does not cause distortion in the handle base and without requiring flat processing, etc., the handle base can be easily processed. The present invention provides a simple structure that can be easily assembled, leads to cost reduction, and is easy to manufacture, so that it can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of a management work machine, in which a front frame 5 is extended to the front part of a transmission case M that has wheels 14 mounted on both sides of the lower part, and an engine E mounted above the front frame 5 is connected to the machine. The transmission case M is equipped with a belt pulley in the belt cover 6 so that power can be transmitted, and the rear part of the transmission case M is equipped with a hitch 7 for connecting a rotary work machine, etc., and the right side of the transmission case M is A PTO shaft 8 for transmitting power to the rotary work machine, etc. is provided protruding from the part, and the structure is similar to that of the conventional type.

Further, B is a handle mounting base, which is formed into a U-shape by simply bending from a flat plate, and holes 10, etc. are formed in the flat top plate 9, and both side plates 11, 1 are formed.
Holes 12 are formed at both ends of each hole 1, and the handle mounting base B is joined to the upper end of the transmission case M, and the bolts 4 inserted through the holes 12 are screwed into the transmission case M. Insert and secure.

At the lower end of the base side of the handle base A, which has both handle rods 1, 1 connected to the tip side, a support plate 2 is fixedly installed to be joined to the top plate 9 of the handle mounting base B. The lower end rim 3 of the base side of the handle base A is slightly fitted into the upper side of the peripheral side surface 2a of the support plate 2 made of
and the surrounding side surface 2a are fixed by welding W so that they do not protrude to the lower surface side of the support plate 2.

The support plate 2 is joined to the top plate 9 of the handle mounting base B, and a clamping plate or the like is interposed therebetween so that the handle base A can rotate, and a threaded portion 16 is operated by the handle lock lever 15. is installed from the handle base A side to the handle mounting base B side, and the handle is installed so that it can be switched from the solid line state to the imaginary line state in the front and back direction in FIGS. 1 and 2, and is configured similarly to the conventional type. , details are omitted.

Therefore, when the support plate 2 is welded to the handle base A, the weld W does not appear on the lower surface of the support plate 2, so there is no need for flattening, and the shaft can be mounted without welding distortion.

Further, the handle mount B can be formed by simply bending the handle.

In this way, the present invention connects the support plate fixed to the lower surface of the base of the handle base that connects the handle rod to the handle mounting base fixed to the upper end of the transmission case, and rotates the handle base to move the aircraft forward and backward. In a management work machine configured to be able to change the handle in any direction, the lower end periphery of the base side of the handle base is fitted to the upper part of the peripheral side of the support plate, and is fixed to the peripheral side by welding, The mounting base was constructed by bending a flat plate into a U-shape and fixing both sides to the transmission case via bolts.The support plate was then welded to the handle base to avoid welding distortion, and the flat plate was machined. It can be easily assembled and fixed by welding without any need, and in particular, since the lower end periphery of the base side of the handle base is fitted to the upper part of the peripheral side surface of the support plate and fixed with the peripheral side surface by welding, Although the welding work can be easily performed from the outside of the handle base, there is no need to flatten the lower surface of the handle base after welding, and the handle base can be manufactured easily.
