Description

  The present invention is an apparatus with extremely high efficiency from forest cutting to new planting / regeneration.

In the forest, when logging is carried out for the production of timber, naturally, about 10-30 cm above the ground remains on the spot. Recently, it is usual to use heavy machinery with a caterpillar structure regardless of whether it is rubber or iron. For this reason, naturally, the root cutting of the spot becomes an obstacle, and trampling this will cause severe damage to the caterpillar and cause a large loss. In many cases, this cannot be solved by the ability of the chainsaw. After all, large heavy machinery is carried in, and the roots that obstruct the carry-out path are dug up, left on the spot, or dumped (in violation of the Industrial Waste Management Law). If left unattended, this may hinder undergrowth and maintenance of new plantations for rehabilitation of forests. Furthermore, the area around the cutting traces will destroy the topsoil, soil will deteriorate, and the growth of new plantations will be significantly inferior.
This is often transported and dumped, and it is a problem to treat this felled root.

  In order to solve the above problems, this “cutting root crusher” is used as an attachment for a small hydraulic excavator, and the hydraulic pressure of the hydraulic excavator is used to rotate the four-blade rotor set at the tip by a hydraulic motor at high speed. The cutting roots were cut into chips in a short time to the same level as the ground, and the obstacles to the transport of caterpillars as well as soil protection were solved.

An embodiment of the present invention is shown in FIG.
Create a "stumps cutting crusher" as the attachment of small-sized hydraulic excavator (commonly known as 0.2m ³ · about 4~5t). This uses the hydraulic pressure of the hydraulic excavator, further increases the rotational speed of the hydraulic motor in the cross-sectional view of FIG. 2, obtains 1000 to 1300 revolutions per minute, rotates the rotor incorporating the four blades at the tip of the attachment, and cuts Repeat the round trip to trace the root from the side.

Effects of the embodiment

  In this embodiment, the ground portion of the cutting root is cut and crushed in a short time. The size of the cutting root to be cut and crushed is not limited. Moreover, since the operator can operate this by one person in the work, an auxiliary worker is unnecessary. The crushed shavings become chips and this becomes fertilizer in the forest, which not only protects the soil, but also significantly reduces the labor required for large heavy machinery and root removal, and the arrangement of them. Made maintenance possible.

Claims (1)

  As a small hydraulic excavator attachment, in a felling root crushing machine that uses the hydraulic pressure of the hydraulic excavator and rotates a four-blade rotor set at the tip by a hydraulic motor at a high speed, the rotor rotates around a vertical rotation axis. It is rotating and incorporates four blades extending in the vertical direction on its side surface. By repeating reciprocation so that the remaining roots of about 10 to 30 cm above the ground are traced from the side surface, the ground part of the felled root is cut and crushed. A cutting and crushing machine that cuts chips into the same level as the surrounding ground and facilitates the running of caterpillar-type transporters.
