Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for crushing waste logs, stumps and the like, and more particularly to a large-sized wood chip crusher.

[0002]

2. Description of the Related Art In recent years, as the living environment has improved, there have been many cases in which previously used buildings have been demolished and replaced, and along with this, demolishing old buildings has been actively carried out. The treatment of waste wood generated when such an old building is demolished becomes a problem, but when such waste wood is transported to a chip factory, after the sorting at the chip factory, depending on the shape of the waste wood, Pre-processing work is done. That is, thin materials such as pillars and pallets of wooden houses are cut into appropriate sizes with hydraulic excavators and forklifts, then put into plants such as conveyors, and large waste wood such as logs and stumps are attached to hydraulic excavators. It is torn into a suitable size or length with a hydraulic excavator fork and then put into the plant.

[0003]

However, in this case, although the treatment of thin materials such as pillars and pallets of wooden houses is not problematic with the present treatment, treatment of large waste wood such as logs and stumps is only possible by tearing. There is a problem in that the length may not be less than or equal to a predetermined dimension, which makes it difficult to put it into a plant. Therefore, in this case, a method of roughly dividing and shortening is desired.

Focusing on the above-mentioned conventional problems, the present invention provides a large-sized wood chip crusher capable of making a predetermined size or less by coarse cracking without tearing logs, stumps, etc. It was made for the purpose of resolution.

[0005]

In order to achieve the above object, a large-sized wood crusher according to the present invention is provided with a clamp member, which can be opened and closed by expanding and contracting a cylinder, at the arm tip of a working machine such as a hydraulic excavator. In addition to being provided, a side cutter for cutting is provided on each side surface of the clamp member to roughly divide it.

Further, in the above construction, the side cutters are roughly divided by being able to cross each other when they are fully closed by both clamp members so as to cross each other.

Further, in the above construction, a cylinder cover that also serves as an ejector is provided on the cylinder to protect the cylinder and remove the crushed material sandwiched between the side cutters.

Further, in the above construction, a tip cutter for tearing a log or the like in the fiber direction is provided at the lower tips of the clamp members to facilitate rough splitting.

[0009]

According to the above construction, when a large timber such as a log is clamped by both clamp materials, it can be easily coarsely divided by the tip cutter and the side cutter. It can be discharged by the ejector provided in the.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in FIGS. Large-sized wood crusher 1 according to the present invention
Is provided at the tip of the arm 12 of the working machine 11 such as the hydraulic excavator 10 shown in FIG. 7 with the clamp members 3 and 4 that can be opened and closed by expanding and contracting the cylinder 2 as shown in FIG.
Side cutters 5 and 6 for cutting are provided on the side surfaces of the clamp members 3 and 4, respectively, and tip cutters 7 and 8 for tearing a log or the like in the fiber direction are provided at lower ends of the clamp members 3 and 4. It is composed of the provided ones.

As shown in the front view of FIG. 5, the detailed structure of the large-sized wood crushing machine 1 is such that the outer clamp member 3 is formed in the shape of a container without a lid, the open side faces forward, and the upper part of the center has a predetermined interval. The pair of brackets 9 and 9 are fixed. The hole provided in this portion and the tip of the arm 12 shown in FIG. 7 are connected by a pin so that they can be operated by an operation from the main body of the hydraulic excavator 10. 1 and 5
, The clamp member 4 is also smaller than the clamp member 3 and is shaped like a vessel without a lid, and the open side faces rearward. Both side plates 4a, 4a are both side plates 3a, 3 of the outer clamp member 3.
It is arranged so as to be inscribed in a and is rotatably connected to the clamp member 3 by a pin 13 provided on the bracket 9. Similarly, the brackets 9 and 9 above the clamp member 3
A bottom end of the hydraulic cylinder 2 is swingably attached by means of a pin 14, and a rod end is provided with a clamp member 4 between them.
A pair of brackets 15 fixed to the lower part of the front of the
Are connected by. Therefore, when the rod of the cylinder 2 is expanded and contracted, the clamp member 4 can be swung with respect to the clamp member 3 by using the pin 13 as a fulcrum, and can be fully opened and fully closed. Side plates 3 of the clamp members 3 and 4
Side cutters 5 and 6 are provided on a and 4a, respectively.

Further, as shown in FIGS. 3 and 4, tip end cutters 7, which are replaceably attached by bolts 17 and 18, respectively to the widthwise tips between the side plates 3a, 3a and between 4a, 4a. 8 are provided. The tip cutters 7 and 8 are provided so as to be in a meshed state as shown in FIG. 3 during the process from full opening to full closing of the clamp members 3 and 4. Further, on the front surface of the clamp member 4, there is a cylinder cover 19 that protects the hydraulic cylinder 2 and also serves as an ejector for removing the crushed material sandwiched between the side cutters 5 and 6, and is linked to the outside of the clamp member 4. 20
Are connected by pins 21 and 22, respectively, and can be rotated by a pin 23 with respect to the bracket 9 of the clamp member 3.

The operation will be described below. First, as shown in FIG. 1, the rod of the hydraulic cylinder 2 is extended to hold the crushed material such as logs from the fully opened state of the contracted clamp member 3.4 of the hydraulic cylinder 2 and the space between the tip cutters 7, 8. If the distance between the center cutters 7 and 8 is shortened and the crushed material comes into contact with the crushed material and then the tip cutter operates to tear the fiber in the fiber direction, the center cutters 7 and 8 are brought into a meshed state as shown in FIG. When the rod of the hydraulic cylinder 2 is further extended from this state, the crushed material is cut by the side cutters 5 and 6, and the clamp members 3 and 4 are fully closed to be in the state of FIG. Next, when the rod of the hydraulic cylinder 2 is shortened, the crushed material sandwiched between the side cutters 5 and 6 is discharged from between the cylinder cover 19 and the clamp member 4.

[0014]

As described above, according to the present invention, the side plates of both clamp members are provided with the side cutters, and the tip ends thereof are provided with the tip cutters. Since it becomes possible to cut with a cutter, and therefore, coarse cracking in the longitudinal direction can be effectively performed, it is easy to put into a plant and the efficiency of coarse crushing can be improved. Moreover, the crushed material sandwiched between the side cutters can be discharged by the eject mechanism of the cylinder cover, and from this point, the efficiency of coarse crushing can be expected to improve.
