Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a reversible bucket device that allows, for example, a gardener, a gas pipe contractor, etc. to selectively perform bucket hoe work and loader work using one machine. It is something.

[Technical background of the invention and its problems]

For example, at the rear of a small bulldozer used by a gardener, etc., there is a bucket device that mainly performs excavation work like a bucket hoe, and a loader like a front loader that loads the excavated soil onto a truck. The main bucket device is 1.
It would be convenient if it could be easily selected and used on a stand.

Conventionally, for example, in a bucket hoe work machine, the shaft support of the bucket was directly connected to the tip of the bucket hoist and the tip of the hydraulic link for rotating the bucket in the vertical direction, respectively, so as to be freely rotatable. When using this bucket for loader work, the two types of pins mentioned above are removed, the direction of the bucket is reversed, and the tip of the bucket is replaced with the tip of the bucket hose stake and the tip of the hydraulically operated link. , 2 for pivoting the bucket
In order to support the bucket in an unnatural posture, the pressure of the hydraulic line such as a hydraulic cylinder used to operate the link may be applied to this pin, so this pin is sometimes used. It is very difficult to insert and remove the pin, requiring a hammer, etc., and the pin becomes stepped due to repeated attachment and detachment, making it even more difficult to insert the pin.Also, when removing the bucket, the last When the pin is removed, the bucket moves from an unnatural position to a natural position, which poses the highest risk of injury to the worker.

[Purpose of invention]

This invention eliminates the need to attach and detach the connecting pins at the tip of the backhorse stake and the tip of the hydraulically operated link for rotating the bucket, which are difficult to attach and detach, thereby simplifying the work of changing the bucket in the opposite direction. The purpose is to facilitate.

[Summary of the idea]

In the reversible bucket cart device of the present invention, the upper part of the bucket support frame is rotatably attached to the tip of the bucket horse stick and the tip of the hydraulic link for rotating the bucket with pins, and the left and right sides of the bucket support frame are A means for fitting the left and right side parts of the bucket to the sides and rotatably supporting the bucket by a rotation shaft, and a means for rotating and fixing the bucket to one side of the bucket support frame and a means for fixing the bucket to the other side of the bucket support frame. This structure is characterized by the provision of means for rotating and fixing the bucket, thereby making it possible to change the bucket cart into a state suitable for backhoe work and loader work.

[Example of idea]

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

As shown in Fig. 1, a pair of connecting brackets 2 are welded and protruded from the upper rear part of a rectangular bucket support frame 1, and a pair of connecting brackets 3 are welded and protruded from the upper front surface. One of the brackets 2 is rotatably attached to the tip of a bucket holder 4 of a bucket hoe working machine by means of a pin 5 inserted therethrough, and the other bracket 3 is attached to the tip of a hydraulically operated link 6 for rotating the bucket. are rotatably attached by pins 7 inserted through these. The link 6 is moved forward and backward by a hydraulic cylinder (not shown) provided on the backhorse stake 4.

Further, as shown in FIG. 1, the left and right side parts of the bucket bag 11 are fitted into the left and right sides of the bag bag support frame 1, and are rotatably supported by a rotation shaft 12. This bucket bag 11 has a front side and an opposite side formed in a symmetrical shape, and teeth 13 and 14 are provided on the edges of the front side and the opposite side, respectively.

Further, on the left and right sides of this bucket 11, stoppers 15 are welded to the inner surfaces as means for rotating and fixing the bucket 11 to one side of the bucket support frame 1, and bolt insertion holes are provided near the stoppers 15. 16, and as a means for rotating and fixing the bucket 11 to the other side of the bucket support frame 1, a stop collar 17 is similarly welded to the inner surface.
A bolt insertion hole 18 is provided near this stopper 17. In addition, at the bottom of the left and right sides of the bucket support frame 1,
A screw hole 19 is provided which is aligned with the bolt insertion holes 16 and 18. In this case, the distances from the bolt insertion holes 16, 18 and the screw hole 19 to the bolt insertion holes 16, 18 and the screw hole 19 are made equal around the rotation axis 12, and the bolt insertion hole 16 and the screw hole are The holes 16, 18, and 19 are positioned so that the bolt insertion hole 18 and the screw hole 19 are aligned with each other and the bucket support frame 1 and the stopper 17 are engaged with each other. A lining plate is placed on the inner surface of the bucket 11 to prevent dirt from adhering to it, and the bucket 11 can be easily turned over.

When performing loader work such as excavating earth and sand and loading the earth and sand onto a transport vehicle, the bucket 11 is moved around the rotation shaft 12 relative to the bucket support frame 1, as shown in FIG. The bucket support frame 1 and the bucket 11 are rotated to the side of the bucket hose stake 4, and the bolt 21 is screwed into the screw hole 19 from the bolt insertion hole 16 positioned by the stopper 15.
and fix it.

When carrying out bucket hoe work, remove the bolt 21 and rotate the bucket 11 to the link 6 side with respect to the bucket support frame 1 around the pivot shaft 12, as shown in FIG. The bolts 21 are screwed into the screw holes 19 from the positioned bolt insertion holes 18 to fix the bucket support frame 1 and the bucket 11.

In addition, the bucket 1 for the bucket support frame 1 mentioned above
1 may be fixed with a pin instead of the bolt 21, and the bucket support frame 1 may be attached with a pin to the tip of the back hose stake and hydraulically operated link of the excavator (power shovel). It's okay.

[Effect of idea]

According to the present invention, the upper part of the bucket support frame is rotatably attached to the tip of the bucket horse stake and the tip of the hydraulic link for rotating the bucket with pins, and the left and right sides of the bucket support frame are attached to the left and right sides of the bucket support frame. The right and left sides of the bucket are fitted together and rotatably supported by a rotating shaft, and the bucket is rotated to one side of the bucket support frame and fixed, and the bucket is rotated to the other side of the bucket support frame. Since a means for fixing the bucket is provided, the bucket can be rotated around the rotation axis independently of the pressure of the hydraulic line, etc., without having to attach or detach the pin on which the pressure of the hydraulic line such as a hydraulic cylinder for rotating the bucket is applied. By simply inverting the bucket and fixing it with bolts or the like, the direction of the bucket can be quickly and easily changed so that bucket hoe work and loader work can be selectively performed. Furthermore, since the bucket cart does not come off the bucket support frame, there is no risk of injury or injury when the bucket cart is turned over.
