Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for facilitating movement of a ridge coater when it is removed from a tractor.

[0002]

2. Description of the Related Art Conventionally, a tractor is mounted on a rear portion of a tractor to excavate a ridge and a surface of an old ridge with a rotating claw member,
2. Description of the Related Art A ridge coating machine is known in which soil is laid on a ridge and the ridge surface is coated and solidified with a ridge molding plate with a vibrator. When removing these conventional ridge coating machines from the work equipment mounting device of the tractor, a stand was used or support rods were erected on both sides to allow easy attachment / detachment and storage as a separate body. .

[0003]

Conventionally, when the ridge coater is removed from the tractor, if it is placed on a stand, it will be difficult to move it to a storage location, so a moving wheel may be provided on one side. In this case, the other side is lifted up so that it can be moved by the moving wheel, but since it moves while holding the stick part on the other side, it is easy for the foot to trip and it is difficult to lift up. Therefore, the present invention intends to provide a handle for movement which can be easily moved and can be equipped with a counterweight.

[0004]

To solve the above problems, the following means are used. That is, in the work machine mounting device at the rear of the tractor, in a ridge coater that is detachably laterally provided with a molding plate, a movable wheel can be attached to and detached from the molding plate side in the left-right direction of the main body case, A support stick is detachably attached to the side, a movable handle is detachably provided on the support stick, and the movable handle can be moved back and forth in the working direction and the storage direction with respect to the support stick.

[0005]

By using such means, when the ridge coater is stored, the moving wheel is attached to one side of the main body case, the support stick is attached to the other side, and the work implement attaching device of the tractor is used. remove. When moving in the detached state, the movable handle attached to the support stick is projected laterally, and the movable handle is held and the other side of the ridge coating machine is lifted and moved. Further, when the left and right balance is poor during work, the support stick is raised and fixed as compared with during storage, the moving handle is extended and fixed, and a balance weight is appropriately attached to the end of the moving handle.

Pivoted by. The left end of the link 24 is pivotally supported by the pivot shaft 26 on the lower end of the link 13, and the link 24 is supported in the horizontal direction. In this way, the link 13 and the link 23 become a parallel link, so that the link 24 can be swung in the left-right direction, and can also be swung in the up-down direction by the floating link 15, and the lifting cylinder 5 can be expanded and contracted. This parallel link itself can be raised and lowered obliquely to raise and lower the ridge forming portion A described later.

A handle 27 is projected downward from the lower portion of the link 13 and a lock pin 29 is projected rearward from the rear surface of the middle portion of the link 13, and the lock pin 29 has a long hole opened at the left end of the lock arm 16. It is inserted to allow the parallel link to swing within the elongated hole. A lock lever 30 is pivotally supported by a pivot shaft 31 in the middle of the lock arm 16, and the lock lever 30 is provided with two notches having different lengths from the pivot shaft 31.
The lock pin 29 can be engaged with the handle 27.
By engaging the notch with the lock pin 29, the swing of the link 13 is fixed, and the ridge molding portion A can be locked at two heights. 32 is the lock lever 3
This is a spring that biases 0 in the locking direction.

A ridge molding portion A is provided at the right end of the link 24, a support plate 33 is fixedly provided at the right end of the link 24, and a vibrating body 34 is suspended from the supporting plate 33 via a spring. Fixes the hydraulic motor M to the side portion so that it is driven by the pressure oil from the hydraulic pump P (FIG. 4) provided on the left side of the main body case 1 to vibrate. The letter-shaped ridge forming plates 35 are arranged so as to be vibrably connected.

As shown in FIGS. 4 and 5, the main body case 1 has a hydraulic oil tank 36 arranged at the upper left of the main body case 1, and a hydraulic pump P is arranged below the hydraulic oil tank 36. Pressure oil can be sent from the pump P to the hydraulic motor M via the pipes 37. Then, connecting plates 40, 41, 41 for connecting to the work implement mounting device of the tractor are forwardly projected to the front part of the main body case 1, the support frame 2 is projected rearward from the center of the rear surface, and the rotary cover 3 is projected rearward from the right side.

2, a support stick 52 is inserted into the insertion portion 42 and is fixed by a pin or a bolt so that the vertical position can be adjusted, a bracket 53 is fixed at a midway portion of the support stick 52, and a movable handle is attached to the bracket 53. 54 is detachably attached, and the bracket 53 has attachment holes 53a.
3b, 53c, and 53d are opened in four places in a quadrangle, and the movable handle 54 is attached to the attachment holes 53a and 53d to be in a housed state. By holding the movable handle 54, one can be lifted and easily moved by the movable wheel 51. The mounting holes 53a, 53b, 53c, 53d can be mounted so that the vertical position and the lateral position can be adjusted. Then, a counterweight 55 can be attached to and detached from the end of the movable handle 54, and the support stick 52 and the movable handle 54 are overhanged and attached during the ridge coating work, and the counterweight 55 is attached to the movable handle 54. The left-right weight balance can be improved.

[0017]

Since the present invention is configured as described above, it has the following effects. That is, the movable handle is attached to the support stick, the support stick and the moving wheel are attached at the same time when the ridge coater is removed from the tractor, and when the movable handle is moved in the removed state during storage, the movable handle is extended to the side. Since it is attached and moves while holding its end, the foot does not get stuck on the support stick, and since it is far from the fulcrum, it can be easily moved with a light force. When the ridge coater is stored, the movable handle can be pivoted downwards to be stored without any hindrance. Also, when the weight balance between the left and right is unbalanced during ridge coating work, the support stick is mounted with it raised, the moving handle is extended and mounted, and the counterweight is mounted on the end to improve the balance. Therefore, it is not necessary to provide a mounting portion for the counterweight.
