DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled timber crusher for crushing branch materials, timber, and the like to a predetermined size at a work site.

[0002]

2. Description of the Related Art For example, it is generated when pruning timber and thinning materials generated when pruning timber cut down in a forest, branch timber generated during development and maintenance of green spaces, or when a wooden house is dismantled. Waste wood is usually ultimately disposed of as industrial waste. The wood crusher is designed to reduce the volume of waste in the waste treatment process, or to ferment the crushed material after crushing and reuse it as organic fertilizer. It is crushed (crushed) to the size of.

[0003] In such a wood crusher, a self-propelled wood crusher in which the crusher is movable to have mobility has been proposed, for example, Japanese Patent Laid-Open No. 2000-15129.
There is one described in Japanese Patent Publication No.

[0004] In this self-propelled wood crusher, a main body frame, running means provided on the main body frame, a crushing device provided on the main body frame for crushing wood to be crushed,
A rotary storage means (rotary tub) provided at an upper portion of the crushing device for receiving and storing the crushed wood from substantially vertically above; and a carry-out conveyor for carrying out the crushed wood crushed by the crushing device. ing. Then, for example, large-sized heavy machines sequentially feed the crushed wood from the upper position into the rotary storage means provided at the upper portion of the crushing device, and the rotary storage means holds a large number of crushed wood in a substantially upright state. Then, the rotary storage means is rotated, whereby a large number of pieces of wood to be crushed therein are sequentially introduced into the crushing device, bitten into the crushing rotor from the lower end thereof, and crushed by the crushing bit.
The crushed wood crushed material falls from the space below the crusher onto the export conveyor below the crusher, is transported by this export conveyor, and is finally discharged from the end of the self-propelled wood crusher. Has become.

[0005]

In the above-mentioned prior art, since the wood to be crushed is introduced from above, a large heavy machine (a hydraulic excavator equipped with a grapple) is required to crush relatively long wood to be crushed. Etc.), the wood to be crushed must be loaded from above the hopper with the axial direction being vertical, so that the worker's work labor becomes extremely large and the input material is liable to be scattered, and the loading is smooth. Was difficult to do continuously.

Therefore, in recent years, a so-called horizontal throw-in type self-propelled wood crusher has been proposed. This self-propelled timber crusher, for example, receives crushed timber received by a receiving means (hopper) disposed at one longitudinal end (front end) on a main body frame on one side in the longitudinal direction on the main body frame. It is transported in a substantially horizontal direction to the crusher side by a transport conveyor provided on the (front side). Then, in front of the crushing device, the press-introducing means cooperates with the conveyor to press the wood to be crushed into the crushing device while introducing the wood to be crushed, and a rotary type disposed at a substantially central portion in the longitudinal direction on the main body frame. The crushed wood is crushed by the crushing rotor of the crushing device, and the crushed material is carried out to the other longitudinal side (rear side) of the main body frame by the carry-out conveyor.

The conveyor is operated by a feed roller provided at the end of the crushing device being driven by a hydraulic motor for the conveyor, and the press-introducing means is provided above the conveyor and near the crushing device. The operation is performed by driving the provided pressing roller by the hydraulic motor for the pressure introducing means. A power unit (power unit) having a power source of the hydraulic motor for the conveyor and the hydraulic motor for the press-introducing means is disposed on the other side (rear side) in the longitudinal direction on the main body frame, and a driver's seat is provided. Is provided on one side of the power body in the lateral direction of the main body frame.

[0008] The self-propelled wood crusher having the above-described structure enables smooth and continuous feeding even when relatively long crushed wood is crushed.

Here, the feed roller constituting the driving wheel of the conveyor and the pressing roller constituting the driving wheel of the press-introducing means are both provided with a rotating shaft in a direction orthogonal to the longitudinal direction of the main body frame. is there. For this reason, the hydraulic motor for the transport conveyor and the hydraulic motor for the press-introducing means that respectively drive these rollers are arranged at either of the both ends in the lateral direction of the main body frame.

Here, when both the hydraulic motor for the conveyor and the hydraulic motor for the press-introducing means are arranged on the same side of the driver's seat and the main frame in the lateral direction of the main body, the driver's gaze in front for traveling is in front of the field of view. The hydraulic motor for the conveyor and the hydraulic motor for the press-introducing means are located on the side.
In particular, since the pressure introducing means is located above the conveyor, the position of the hydraulic motor for the pressure introducing means is relatively high, and the driver's view is largely obstructed. As a result, in terms of ensuring safety, there is a possibility that the mobility of the self-propelled wood crusher by self-propelled operation may be impaired, for example, the site conditions at which the vehicle can travel are limited, or the traveling speed is limited to an extremely low speed. is there.

An object of the present invention is to provide a self-propelled wood crusher capable of improving the mobility while facilitating smooth and continuous feeding of long crushed wood.

The pressure introducing means cooperates with the conveying means to press the object to be crushed while introducing the crushed object into the crushing device for crushing. By setting the flow of the crushed object as described above, even when relatively long crushed wood is crushed, smooth and continuous introduction can be easily performed.

At this time, the conveying means operates by driving a feed roller provided at the end of the crushing device side by a hydraulic motor for the conveying means. However, in the present invention, the hydraulic motor for the pressure introducing means is provided on the other side in the short direction on the main body frame. Thereby, the hydraulic motor for the press-introducing means, which may greatly obstruct the driver's view at a relatively high position above the conveying means, is provided on the side opposite to the driver's seat provided on one side in the short direction of the main body frame. Since they are arranged, a good front view from the driver's seat can be secured. Therefore, the mobility of the self-propelled wood crusher by self-propelled running can be improved.

Next, the operation and operation of this embodiment will be described below.

(1) At the time of running operation In the self-propelled timber crusher having the above-mentioned configuration, for example, when the self-propelled timber crusher travels on a flat ground in an operation site, or for loading on a trailer to head to the operation site. In the case of self-propelled operation such as when traveling on the trailer carrier or when traveling on its own to descend from the trailer carrier after arriving at the operation site, the operator (driver) rides in the driver's seat 95 and operates the operating lever. 96a is operated forward.
As a result, the left and right traveling control valves (not shown) are switched, and the hydraulic oil discharged from the hydraulic pump is supplied to the left and right traveling hydraulic motors 12, which are driven in the forward rotation direction, and the endless The track crawler belt 11 is driven in the normal rotation direction, and the traveling body 6 travels forward.

During this traveling, the driver performs the traveling operation while gazing at the front (especially, there is no obstacle on the ground on the lower front side, whether there is a person, etc.). In a so-called horizontal loading type self-propelled timber crusher provided with a feed roller 33 and a holding roller 45 provided with directional rotation shafts 33a and 45a, respectively, only the convenience of maintenance by an operator (driver) is considered. hand,
When both the feed conveyor hydraulic motor 41 and the presser conveyor hydraulic motor 91 are arranged on the left side of the self-propelled wood crusher near the driver's seat 95 so that the operator can reach the shortest distance, There are inconveniences. That is, in this case, as described above, the hydraulic motor 41 for the feed conveyor and the hydraulic motor 91 for the presser conveyor are located in front of the field of view of the driver who gazes forward for traveling. In particular,
The position of the presser conveyor hydraulic motor 91 is relatively high, which greatly obstructs the driver's view. As a result, in terms of ensuring safety, there is a possibility that the mobility of the self-propelled wood crusher by self-propelled operation may be impaired, for example, the site conditions at which the vehicle can travel are limited, or the traveling speed is limited to an extremely low speed. is there.

Therefore, in this embodiment, of the hydraulic motors 41 for the feed conveyor and the presser conveyor, the hydraulic motor 91 for the presser conveyor is
Installed on the right side of the self-propelled wood crusher. As a result, the presser conveyor hydraulic motor 91, which may greatly obstruct the driver's view, is disposed on the opposite side of the driver's seat 95, so that the front view from the driver's seat 95 can be reliably secured. Therefore, the mobility of the self-propelled wood crusher by self-propelled running can be improved.

(2) At the time of crushing operation At the time of the crushing operation, when the crushed object is put into the hopper 1 by, for example, an appropriate working tool or a manual operation (manual power), the crushed object received by the hopper 1 is transported by the feed conveyor 2. It is placed on the body 35 and transported substantially horizontally behind the self-propelled timber crusher (to the right in FIGS. 1 and 2).

When the crushed material conveyed backward in this way reaches the vicinity of the rear end (the right end in FIGS. 1 and 2) of the feed conveyor 2, the upper part thereof is the conveyance body 47 of the presser conveyor 4.
Is held by the holding conveyor 4 so as to enter the lower part of the container, and is held by being pressed by the own weight of the holding conveyor 4, and is sent to the crushing device 3 while being held by the rotation of the carrier 47.

At this time, in FIG.
The crushing object W (shown by imaginary lines in FIG. 5) is vertically moved in cooperation with the pressing roller 45 at the end of the crushing device 3 and the feed roller 33 at the end of the crushing device 3 of the feed conveyor 2. The crushing portion X (see FIG. 5) is used as a crushing fulcrum at the time of crushing (hereinafter, appropriately referred to as crushing fulcrum X), and the tip of the crushed object on the side of the crushing device 3 is directed toward the crushing rotor 21. The crushing bit of the rotating crushing rotor 21 crushes (crushes) the protruding tip portion one after another. The crushed wood crushed material is sorted by the opening of the sieving member 32, and only the crushed wood having a particle size capable of passing through is discharged to the outside of the sieving member 32. The discharged wood crushed material falls onto the belt 86 of the unloading conveyor 7 via the chute and is transported.
Finally, it is discharged (conveyed) as a recycled product from the rear part (right end in FIG. 1) of the self-propelled wood crusher.

By making the flow of the so-called horizontal input type crushed material as described above, in the present embodiment, even when relatively long crushed wood is crushed, smooth and continuous Input can be easily performed.

As described above, according to one embodiment of the self-propelled wood crusher of the present invention, the maneuverability is improved while smoothly and continuously feeding long crushed wood. The effect that can be obtained.

The present invention is not limited to the embodiment described with reference to FIGS. 1 to 5, and various modifications can be made without departing from the spirit and technical idea. . Hereinafter, such modified examples will be sequentially described.

Structure in which the position of the hydraulic motor for the feed roller is also shifted to the opposite side. That is, as shown in FIG. 6 corresponding to FIG. 3 of the embodiment of the present invention, the hydraulic motor 41 for the feed conveyor and the presser conveyor This is a case where both hydraulic motors 91 are arranged on the right side of the self-propelled wood crusher.

In this modification, not only the hydraulic motor 91 for the presser conveyor but also the hydraulic motor 41 for the feed conveyor is disposed on the side opposite to the driver's seat 95.
The visibility of the front side from above can be secured more favorably, and the effect that the mobility of the self-propelled timber crusher can be further improved can be obtained.

A structure in which a driving force is transmitted from a hydraulic motor for a feed roller using a pulley. That is, as in the above-described embodiment of the present invention, the rotation of the feed roller 33 from the hydraulic motor 41 for a feed conveyor via only a coupling 42. Instead of directly transmitting the driving force to the shaft 33a, as shown in FIG. 7 (corresponding to FIG. 1 of the embodiment of the present invention), the feed conveyor hydraulic motor 41 is shifted slightly downward (shown in FIG. 7). In the example, it is provided on the intermediate frame 13 or in the mounting frame 14) and is driven via a pulley belt 90 bridged between a pulley (not shown) provided on the drive shaft thereof and a pulley 33aa provided on the rotary shaft 33a. This is the case when transmitting force.

In this case, there is an effect that the degree of freedom of arrangement of the feed conveyor hydraulic motor 41 is increased as compared with the direct connection type. In particular, when the hydraulic positions of the feed conveyor hydraulic motor 41 and the presser conveyor hydraulic motor 91 are on the same side as in the above-described modified example, the two are close to each other and are easily subject to restrictions. It is effective to adopt this structure on the hydraulic motor 41 side.
