Description

  TECHNICAL FIELD The present invention relates to an apparatus for bundling a forest land residual material that is generated when a whole forest is collected and loaded after a mountain forest is cut down.

  The raw wood that has been cut down from the forest and collected at the base of the local mountain is cut into branches and treetops to form logs of a predetermined length, and then stacked. In most cases, branch trees and treetops cut off from raw wood, that is, residual woods, are left in the state of being cut off near the gathering ground at the local mountain. In this way, the remaining forest land left in the local mountain area becomes an obstacle to the loading work, and it flows out during heavy rains, causing driftwood damage and waste damage. It will decay when left unattended for a long time. Forest land residue is used as a biomass resource, but in order to accumulate and load in a cut-off state, the bulk density is low and the moisture content is high, so the transportation efficiency is very low and it is not profitable. It is hardly used.

  In order to solve such problems, it is possible to collect the remaining forest land, reduce the volume, bundle it into a bundle of a predetermined thickness and length, accumulate and store for a certain period, dry it, and then load it at the local mountain. Conceivable. By bundling and storage and drying, the remaining forest land has a high bulk density and a low moisture content, improving transport efficiency and potential for use. As an apparatus for binding such forest residue, use of a waste wood packing apparatus (see Patent Document 1) is conceivable. This device is a device for increasing the efficiency of loading work and increasing the loading efficiency when waste wood discharged from a building demolition site is carried out by truck.

  That is, the waste wood packing device is constituted by a waste wood container, a bending device, a folding device, a pushing device, a pushing device, and a binding device. The waste wood container is a rectangular cylindrical container whose upper and lower surfaces are open, and its bottom surface is constituted by a push-up plate of a push-up device that can push up the inside of the container. The folding device is configured such that a folding plate rotatably supported at one upper end of one long side of the waste wood container can be rotated and pushed into the waste wood container. The convolution device is configured such that a convolution plate rotatably supported on the upper ends of both short sides of the waste wood container rotates and can be pushed into the waste wood container. The pushing device is configured such that the pushing plate can be pushed into the waste wood container from above the waste wood container at the time of pushing, and the rest can be waited along the outer surface of the waste wood container. The bundling device is disposed at the upper end of the other long side of the waste wood container.

  In such a waste wood packing device constituted by each device, the waste wood is placed so as to straddle the waste wood container between the upper ends of the opposed short sides of the waste wood container, and the folding device, the folding device and the pushing device are arranged. Are sequentially bent and pushed into a waste wood container, reduced in volume and bound, and then pushed up by a push-up device and discharged from the waste wood container. Through the above series of operations, the waste wood is reduced in volume and bound, and this series of operations is repeated.

  Moreover, there is a binding device for remaining forest land with the configuration shown in FIG. 4 (see Non-Patent Document 1). In FIG. 4, what is indicated by reference numeral 30 is a bundling device, and the bundling device 30 has a feeder 31 that also serves as a first volume reduction machine as an upstream end, and sequentially transfers a transfer machine 32, a second volume reduction machine 33, The third volume reducing machine 34, the binding machine 35, and the cutting machine 36 are configured in a straight line on a gantry (not shown). The feeder 31 that also serves as the first volume reducing machine is arranged upright and spaced apart from each other in the left and right direction, and is constituted by two rollers with protrusions that are driven to rotate by a hydraulic motor. The transfer machine 32 is configured by two rollers with projections that are spaced apart from each other in the vertical direction and are horizontally arranged so that the distance can be adjusted. The second volume reducer 33 and the third volume reducer 34 are configured such that the inner diameter of a cylindrical passage having a polygonal cross section perpendicular to the axis can be reduced by a hydraulic cylinder. The binding machine 35 is configured by adding necessary improvements in accordance with the use of the binding machine for packing and packing. The cutting machine 36 is constituted by a chain saw. In addition, the 3rd volume reduction machine 34 and the binding machine 35 are united, and it is comprised so that linear reciprocation between the 2nd volume reduction machine 33 and the cutting machine 36 is possible.

In the bundling device 30 configured in this way, first, forest land residue is supplied to a feeder 31 that also serves as a first volume reducer, and left and right by a feeder 31 and a transfer machine 32 that also serve as a first volume reducer. The direction is continuously reduced and the volume is reduced in the up and down direction, and the bundle is loosely supplied in the downstream direction and enters the second volume reduction machine 33. Next, in the second volume reduction machine 33, the bundle of forest land residual material is reduced by tightening from the surroundings adjusted as appropriate, and the transfer of the feeder 31 and the transfer machine 32 also serving as the first volume reduction machine It is pushed downstream by the action and taken up by the third volume reducer 34 and the binding machine 35 that have moved backward. Next, the tightening of the second volume reduction machine 33 is loosened, and the third volume reduction machine 34 and the binding machine 35 that have taken up a bundle of forest land residual material are the supply machine 31 and the transfer machine 32 that also serve as the first volume reduction machine. Along with the transfer action, the third volume reduction machine 34 advances to the front of the cutting machine 36 and stops while tightening and holding the bundle of the remaining forest land. During this time, the remaining forest land bundle advances while being finally reduced in volume by the tightening of the third volume reducer 34, is bundled by the binder 35 in the tightened state, and is sent to the cutting machine 36. Next, the second volume reducing machine 33 reduces the bundle of the remaining forest land by tightening, and the third volume reducing machine 34 that has loosened the tightening moves backward together with the binding machine 35 to immediately before the second volume reducing machine 33, and then Tighten and hold a bundle of residual forest land. In the same manner, the third volume reducer 34 and the binding machine 35 reciprocate between the second volume reduction machine 33 and the cutting machine 36, and the reduced and bound forest land residue is sequentially sent to the cutting machine 36. In the cutting machine 36, the remaining forest land material that has passed through the cutting machine 36 is cut when the passing length reaches a predetermined length.
