Description

  The present invention relates to an improvement of a walking type management work machine that performs a tilling work by attaching a tilling claw to a tilling shaft that also serves as an axle.

  Conventionally, a small walk-type management work machine called a forward rapid tilling type that attaches tilling claws to a tilling shaft that also serves as an axle is used to move a tail wheel by attaching a wheel to a resistance rod attached to the rear when moving on a pavement etc. Then, the vehicle was driven by a tail wheel while the handle was pushed down and the rotor portion was lifted, or the tilling claw attached to the axle was removed and replaced with a wheel.

  However, it takes effort to attach the wheel to the resistance rod, lift the rotor part and drive it manually, and to change the tillage claw and the wheel, it takes time to change each time it is plowed and moved. In addition, there is a problem that it is inconvenient to carry the removed tillage nail when moving.

  The problem to be solved by the present invention is that, in a forward-type quick-plow type walking type management work machine in which a tilling claw is attached to a tilling shaft that is also used as an axle, when traveling on a pavement or the like, it takes effort to install and move wheels. It was a point that took time and effort. That is, an object of the present invention is to provide a walking type management work machine that can travel on a pavement without attaching extra effort by attaching wheels to an axle by a simple method.

  In order to solve the above-mentioned problems, the present invention, as described in claim 1, forms wheel mounting holes at the left and right ends of the tillage shaft inserted through the lower output side of the transmission case at the center of the fuselage. A plurality of pins around which the head portion is larger than the shaft portion are arranged at equal intervals, and each of the pair of wheels having a diameter larger than the rotation radius of the tilling claw radially attached to the tilling shaft is integrated with the wheel on one side. The mounting plate is fixed, and the mounting plate is provided with a plurality of arc-shaped long holes around the wheel axle at equal intervals, the insertion holes being formed in the long holes larger than the heads of the pins, and Insert the wheel axle into the wheel mounting hole of the tillage shaft and insert the head of the pin into the insertion portion of the long hole and turn the wheel along the long hole to move the pair of wheels to the left and right ends of the tillage shaft. It is characterized by being freely mountable

  As described in claim 2, the insertion portion has a long hole portion on the front side in the rotational direction when the tilling shaft is rotated forward.

  As described in claim 1, since the connecting portion is provided on both sides of the outermost end of the tilling shaft and the mounting plate is provided on the wheel, the wheel can be connected to the tilling shaft with the tilling claw being attached. There is no need to remove and carry the claws, and the wheels can be driven to travel comfortably. Furthermore, since the head portion is formed larger than the shaft portion of the pin, the head portion is locked to the edge of the elongated hole so that the pin does not come off and is not removed. Furthermore, since the connecting shaft is formed longer than the pin, first insert the connecting shaft of the mounting plate into the wheel mounting hole, align the centers of each other, and then rotate one of them to insert the pin into the insertion portion. The wheel can be easily connected to the tilling shaft.

  As described in claim 2, by providing an insertion part at the middle part of the long hole or at the rear side during normal rotation of the tilling shaft, the pin is attached to the front end of the long hole even when the wheel is attached to the tilling shaft for driving. Since it is located, it is possible to prevent the pin from coming off from the insertion portion during running and removing the wheel.
