Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a stone and debris removal bucket that is used by being attached to a bucket.

[Conventional technology]

As shown in Fig. 7, a bucket 20 with a net-shaped side surface and outer circumferential surface is attached to excavate mixed soil such as a field containing stones and gravel using a bucket hoe 1, and the bucket 20 is vibrated up and down to separate and fall the soil. There is a way to remove gravel. This method vibrates the mixed soil only in the vertical direction, so in order to separate the soil sufficiently, it must be vibrated several dozen times, which is extremely inefficient and eliminates soil adhering to stones. cannot be separated by vertical vibration alone. Further, there are disadvantages in that the bucket 20 may be damaged in a short period of time due to excessive vibration, and the hydraulic system of the bucket hoe 1 may be overloaded, resulting in frequent failures. In addition, a gravel removal bucket equipped with an outward-opening lid has been devised, but if the lid is left open when excavating mixed soil and performing a rotational operation, the lid will come into contact with the arm of the bucket and break. (see figure). Therefore,
It is difficult to operate because the bucket must be rotated while closing the lid. As a result, there are many errors in operation, which lead to damage to the lid, and eventually to the bucket body and backhoe.

[Problem that the invention attempts to solve]

The present invention eliminates the drawbacks of the prior art and provides a durable and efficient gravel removal bucket.

[Means to solve the problem]

In order to solve the above problems, the present invention has the following configuration. A lid that opens inward is provided on the excavation part of the net box-shaped bucket that is attached to the bucket hoe.

【Example】

Embodiments of the present invention will be described below based on the drawings. Figure 1 is an enlarged sectional front view of the main part of the lid, Figure 2 is a front view, Figure 3 is a plan view, Figure 4 is a left side view, Figure 5 is a right side view, Figure 6 is a front view of the camera attached to a backhoe. A box-shaped bucket 10 is formed by making one corner of the upper surface of a horizontally long rectangular parallelepiped an acute angle. An excavating blade 11 is fixed to the acute angle slope 10a side of the bucket 10. A mounting fitting 12 that fits into the arm of the bucket hoe 1 is provided at the center of the upper surface of the bucket 10. The entire outer surface of the bucket bag 10 is formed into a net shape except for the upper surface of the bag with an acute angle. A net-like lid 13 is arranged at a substantially right angle in the center of the acute-angled slope 10a, and its base is connected to the blade 11 and the mounting bracket 1.
Pivotally attached to the top surface of the bucket 10 approximately in the middle of 2,
Use as a fulcrum. Furthermore, an arbitrary number of overhanging arms 13a are provided on the lid 13, and a hydraulic cylinder 14 is pivotally attached to the tip of the overhanging arms 13a and the bucket 10. When the hydraulic cylinder 14 is extended [hydraulic pressure is supplied from the backhoe 1], the lid 13 rotates inward and becomes almost parallel to the acute corner surface 10a, so that the lid 13 is connected to the inlet A.
1, form A2. The bucket tote 10 having the above structure is attached to the arm of the backhoe 1 via the mounting fitting 12, and is attached to the backhoe 1. In FIGS. 6 and 1, the lid 13 of the bucket 10 attached to the bucket hoe 1 is opened as shown by the solid line, and the mixed soil B is excavated. Next, when the bucket 10 is rotated to the position shown by the chain line with the lid 13 open, the mixed soil B flows through the inlet A1,
The soil falls downward into the bucket 10 through A2, and the soil separates from the mesh and falls. Then, when the lid 13 is closed and the bucket 10 is rotated in the opposite direction to the position shown by the solid line, the mixed soil falls in the opposite direction, the soil separates from the mesh, and the gravel is stopped by the lid 13. By repeating this rotating operation several times, the mixed soil moves back and forth inside the bucket 10, and the soil is efficiently separated and dropped from the mesh. Further, since the stones and gravels are rolled and reciprocated in the bucket 10, soil attached to the stones can be separated. The gravel remaining in the bucket 10 is discharged when the lid 13 is opened and rotated to the position shown by the solid line in FIG. 6, so that it is discharged to a depositing place or to a loading platform such as a truck. Since the bucket 10 only rotates back and forth a few times, it is durable without being subjected to excessive load, and there is no problem with the hydraulic system of the bucket hoe 1. Furthermore, since the lid 13 opens to the inside of the bucket 10, there is no object protruding to the outside, and when the bucket 10 is rotated, there is no object that comes into contact with the arm of the bucket hoe 1, so there is little chance of damage.

[Effect of the idea]

As mentioned above, soil adhering to stones and gravel can be separated by several rotations of the bucket 10, which is efficient, and since the bucket 10 is not overloaded, there is less damage and durability, and the hydraulic pressure of the bucket 1 is There are no system failures. Also, since the lid 13 opens inward, the lid 1 of the bucket 10
There is no need to perform difficult operations such as rotating the bucket 10 while closing the lid 13, and damage to the lid 13, the bucket 10, and the bucket due to erroneous operation is eliminated.
