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 the possibility of soil adhering to stones and gravel. cannot be separated by vertical vibration alone. Further, due to excessive vibration, the bucket 20 may be damaged in a short period of time, and the hydraulic system of the bucket hoe 1 may be overloaded, resulting in frequent failures.

[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]

Hereinafter, the configuration of the present invention will be explained based on the drawings. Figure 1 is a front view, Figure 2 is a top view, Figure 3 is a bottom view, Figure 4 is a left side view, Figure 5 is a right side view,
FIG. 6 is a front view of the device attached to a backhoe. A cutting blade 11 is attached to one corner of the upper surface of a horizontally long rectangular parallelepiped at an acute angle to form a box-shaped bucket 10 whose entire outer surface is mesh-like. 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. A lid 13 is formed on a part of the upper surface of the bucket 10 on the side where the blade 11 is attached, and its base is pivoted. The tubes of an arbitrary number of hydraulic cylinders 14 are pivoted to the bucket 10, and the tips of the rods are pivoted to the lid 13, respectively, so that the lid 13 can be freely opened and closed (hydraulic pressure is supplied from the backhoe 1). 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 FIG. 6, as shown by the solid line, the lid 13 of the bucket 10 attached to the backhoe 1 is opened and the mixed soil is excavated. Next, when the lid 13 is closed and the bucket 10 is rotated to the position shown by the chain line, the mixed soil falls downward and the soil separates from the mesh and falls. Next, when the bucket 10 is rotated in the opposite direction with the lid 13 closed to the position shown by the solid line, the mixed soil falls in the opposite direction, and the soil separates from the mesh and falls. By repeating this rotation several times, you can
The mixed soil reciprocates inside the mesh, and the soil is efficiently separated and falls 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 stones and gravel remaining in the bucket 10 are discharged when the lid 13 is opened in the position shown by the solid line in FIG. Since the bucket 10 rotates only a few times, it is durable without being subjected to excessive load, and there is no failure of the hydraulic system of the bucket hoe 1.

[Effect of the idea]

As mentioned above, it is efficient because the soil attached to the gravel can be separated by several rotations of the bucket 10, and it is durable because the bucket 10 is not overloaded, and there is no possibility of failure of the hydraulic system of the bucket 1. None.
