Description

Log Deflectors for Excavators and Forest Equipment

The present invention relates to a log deflector for excavator and forest equipment (Log Defletor for Excavator and Forestry Machine), and more specifically in the workplace by varying the fixed posture and fixed angle of the support for log deflecting performance The present invention relates to log deflectors for excavators and forest equipment, which can adapt to changing types of wood or working conditions and improve worker access.

Typically, excavators are used for loading and transporting soil or wood at construction sites using work tools including booms, arms and buckets, and as an optional device for transporting timber instead of buckets to the tip of the boom. It is used as a forest equipment, including a grip device or a tree harvester head for cutting and barking wood.

Depending on the type, length and size of the wood, a rotary vegetation removal unit with a cutting blade may be attached as a work tool instead of the tree harvester head described above.

As one of such prior arts, an excavator equipped with a rotary vegetation removal device is disclosed in Korean Patent Publication No. 2012-0019093 (published on March 06, 2012). However, in the process of processing wood, the wood hanging on the tip of the boom approaches the upper pivot side, in some cases colliding or falling off the upper pivot. Therefore, various researches and developments of a log deflector are carried out as a device for supporting the timber approaching the upper swing side or protecting the mechanical elements of the upper swing which may be damaged by the collision of the wood. have.

1 is a schematic diagram showing an excavator and forest equipment with a tree harvester head.

Referring to the drawings, the excavator and the forest equipment is rotatably mounted on the lower running body (2) running the work site by the track unit, the upper turning body (1) is the upper frame ( On 3) mechanical elements, including the cab 4 and the engine compartment 9, the fuel tank 12 and the toolbox 10, are mounted. For the handrail on boarding the upper frame 3, the handrail may be disposed in the front and rear direction to be fixedly supported by the tool box 10 and the fuel tank 12.

On the front center portion of the upper frame 3 or on the upper frame 3 on the cab side, the boom 5 and the arm 6 are installed as a work device so as to be driven by the respective hydraulic cylinders 8, the arm 6 At the tip of the tree harvester head (7) is mounted for the transport and processing of wood (W).

In the process of transporting and processing wood (W), one side of the wood (W) is caught in the tree harvester head can be removed or cut and transported, in this process one side or end of the outer peripheral surface of the wood (W) A collision occurs on the mechanical elements of the upper swing structure.

Accordingly, there is a disadvantage in that damage to the mechanical elements on the upper swing structure is frequent during the processing and transportation of wood.

Depending on the machine's specifications, the log deflector structure may be configured on the upper frame to stand adjacent to the toolbox in the form of a combined protective and support bracket with panel and post elements, but such a conventional log deflector may be subjected to partial damage. There is a problem that the entire equipment must be replaced.

In addition, since the conventional log deflector is manufactured and configured by the driver in the front access type on the upper frame, maintenance and replacement work are difficult and inefficient.

The present invention was created to solve the above problems,

The purpose of the present invention is to provide log deflectors for excavators and forest equipment, which can efficiently support wood and protect the mechanical elements of upper swing structure according to the type and size of wood and working conditions.

Another object of the present invention is to provide a side access on the upper frame when attaching the handrail to increase the accessibility of the operator and to increase the convenience and efficiency of maintenance or replacement work log for the excavator and forest equipment To provide a deflector.

Log deflector for excavators and forest equipment according to the present invention, the angle of the support 40 can be variably adjusted according to the type and working conditions of the wood (W), as shown in Figure 4a and 4b, When the support member 50 is supported between the second fixing hole 34 of the guide rail 32 and the support member 44 of the support 40, the support fixing angle becomes relatively large, and the auxiliary support member 50 ) Is supported between the third fixing hole 35 of the guide rail 32 and the support 44 of the support 40, the support fixing angle is relatively small.

This is because the rotation of the support 40 is fixed to the fixed posture and the support fixed angle is set to rotate counterclockwise when viewed relative to the front and rear direction of the upper frame (3) for the collision and support for the wood (W) It should be interpreted as possible. For example, the fixed angle of the support 40 shown in FIG. 4A may be greater than the fixed angle of the support 40 shown in FIG. 4B, thus supporting and dispersing the impact and load of the wood W. There is also a difference in performance.

If a long-term use process or maintenance is required, breakage or damage of the support 40 or the auxiliary pedestal 50 may occur. In this case, the operator may fix the first fixing member 45 and the second fixing member 46. By disassembling, repair and replacement of damaged parts can be done efficiently. Therefore, only the damaged parts can be repaired and replaced without the need to replace the entire structure of the log protector equipment as in the prior art.

Even when the bracket 30 or the guide rail 32 is damaged, since the detachable from the base 20 is possible, there is an advantage that maintenance can be performed at a low cost.

On the other hand, the hand rail 13 can be fixed to the back of the base 20, in this case the hand rail 13 is disposed along the transverse direction of the upper frame 3 to improve the accessibility and convenience of the operator do.

Although the above embodiments have been described in detail with reference to the accompanying drawings and embodiments, the accompanying drawings and the above embodiments have been described by way of example to help those skilled in the art to understand the present invention. . Accordingly, the above embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention should be construed in accordance with the invention set forth in the appended claims, the scope of which should be understood by those skilled in the art. Include various changes, alternatives, and equivalents by

The log deflector for the excavator and forest equipment according to the present invention can maintain the log deflecting performance by appropriately supporting the impact and load of the wood in response to the type or working conditions of the wood that are variously changed in the workplace. If necessary, only damaged parts can be replaced, and the side access function is useful for operator access and maintenance.
