Description

[Detailed Description of the Invention] The present invention relates to a bucket structure for a hand dozer with a bucket hoe.

Conventionally, hand dozers equipped with a bucket hoe have been able to perform excavation work with a bucket as well as levying the earth with an earth removal plate. , it is not possible to cut the roots of the plant,
Root cutting must be done separately before or during excavation, which is inefficient and can cause unexpected force to be applied to the aircraft through the bucket and the boom that supports it, causing the aircraft to float. Yes, it was dangerous.

In the present invention, a saw-shaped cutter is provided protruding from the tip edge of the bucket opening along the tip edge, and when performing excavation work in a place where plants have been planted, the saw-shaped cutter can be used to cut roots, etc. It is an object of the present invention to provide a bucket structure for a hand dozer with a bucket hoe, which can improve work efficiency and prevent the risk of the aircraft floating due to unexpected force being applied to the aircraft body via the boom.

An embodiment of the present invention will be described in detail based on the drawings.
A indicates a hand dozer with a backhoe,
This hand dozer A with a bucket hoe has a bucket working part 1 disposed in the front part of the hand dozer body a, and the hand dozer body a has a prime mover casing 3 housing the prime mover in the upper front part of the body frame 2. Behind it, a hydraulic oil tank 4 housing a hydraulic pump inside is arranged, a hydraulic control valve 5 is arranged behind it, an operation column 6 with various operating levers is arranged behind it, and the aircraft body A crawler type running section 7 is arranged on the lower side of the frame 2,
An earth removal device 8 is arranged in front of it.

In addition, the bucket work section 1 has a pivot connected to a bracket 9 formed at the front end of the fuselage frame 2, and the base end of the main boom 11 is pivoted to a connecting body 10 connected to the same axis. Vice boom 1
2, and a bucket 13 is pivotally supported at the tip of the sub-boom 12.

Here, the structure of the bucket 13 will be explained as follows. That is, the bucket 13 has side cutters 14, 14 arranged on the left and right outer sides of the bucket main body 13', and both side cutters 14,
The cutting edges 14 project from the left and right side edges 16, 16 of the bucket opening 15, respectively. Moreover, three claw bodies 17 are arranged side by side in the left-right direction on the outside of the front side of the bucket main body 13', and the tips of the claw bodies 17 are respectively projected from the front edge 18 of the bucket opening 15. Further, a plate-shaped saw-shaped cutter 19 is detachably disposed inside the front side of the bucket main body 13', and the saw-shaped cutter 19 has its cutting edge at the base end position of the claw body 17 at the front edge of the bucket opening 15.
It stands out from 8.

The saw-shaped cutter 19 is formed longitudinally in the left-right direction, and its left and right edges are aligned with the inner sides of the left and right claws 17, 17, respectively, and the front edge except for the portion facing the center claw 17 is formed. left and right,
Each of them forms four consecutive blades 20,
Therefore, blades 20 are formed between each of the claw bodies 17, respectively. The shape of the blade 20 is
It has a nearly triangular protruding state with the width reduced toward the tip, and the left and right side parts corresponding to that side are shown in Figure 3 A,
The blade edge 2 is tilted as shown in B and Figure 4 A and B.
1 is formed. This inclination means that when the side of the saw-shaped cutter 19 that contacts the bucket main body 13' is the back side and the opposite side is the front side, there are two types: an outward downward slope from the front side to the back side, and a back side. In the former case, the blade edge 21 is formed on the back side, and in the latter case, the blade edge 21 is formed on the front side.
In FIGS. 3A and 3B, the left and right side portions of one blade 20 are unified to have an outward downward slope from the front surface to the back surface, so that a blade edge 21 is formed on the back surface side.

In addition, in Fig. 4 A and B, the right side of the blade 20 is sloped outward from the back to the front, and the left side is sloped outward from the front to the back, that is, the left and right sides are sequentially formed. The blades are inclined alternately, so that the blade edges 20 on the left and right sides of the blade 20 are sequentially formed alternately on the front and back sides of the saw-shaped cutter.

The side cutter 14 has a protruding edge formed in a W-shape when viewed from the side, and its front edge 22 and lower edge 23 are each inclined from the outside to the inside, and a blade edge is formed on the outside side. It is structured as possible.

Note that the present invention is not limited to the above-mentioned embodiments, and the formation state of the blade edge 21 of the saw-shaped cutter 19 is not limited to that shown in FIGS. Of course it is okay to do so.

The embodiment of the present invention is constructed as described above, including a main boom 11, a sub-boom 12, and a bucket 1.
3 excavates the ground surface with the bucket 13 by its own operation, and when performing such work, even if tree roots etc. are on the ground surface, the bucket main body 13' will not invade the ground surface. The roots of the tree are cut in advance with the saw-shaped cutter 19 and the side cutter 14, so that the bucket main body 13' can enter the ground surface smoothly, and the bucket main body 1
This prevents unexpected force from being applied to 3' due to entanglement with tree roots, thereby preventing the danger of the aircraft floating.

According to the present invention, a saw-shaped cutter is provided protruding from the tip edge of the bucket opening along the tip edge, so that roots can be cut with the saw-shaped cutter when excavating at a place where plants have been planted. In addition to improving work efficiency, it is possible to prevent the risk of unexpected force being applied to the aircraft body via the boom and causing the aircraft to float.
