Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driver's seat provided on a vehicle body, and a trunk or branch of a fruit tree or the like pruned by traveling in a field by a driving power source into chip-like debris. The present invention relates to a riding grinding device for grinding.

[0002]

2. Description of the Related Art When caring for orchards and gardens such as apples, thighs, and tangerines, pruning is performed to cut off unnecessary trunks and branches of trees. In many cases, the pruning operation is manually performed by an operator using a saw or a pinch for each tree. The cut trunks and branches are collected on the spot or in one place, and are sized to be easily handled, transported to a safe place, and disposed of by incineration. The pruned stems and branches may be handled by workers with pinches or hatches, but recently cutting devices have been developed to save various labor because workers hurt their hands and workability is poor. Has been put to practical use. For example, a cutting device that cuts a branch by using air scissors that communicate with a compressor driven by an engine through a hose and operating a pinch by air pressure is used.

[0003] In addition, a pulverizer for further pulverizing the processed wood chips into chips has been developed and put into practical use when there is no place or space for incineration or from the viewpoint of environmental protection. This crusher is provided with a rotary cutter that is driven to rotate by an engine, and when the processed piece is thrown in from an inlet, it is crushed into chips and discharged from an outlet. Chip-shaped crushed pieces crushed by the crusher are used as fertilizer by sowing them around fruit trees or in fields, or by laying them on grassland and returning them to soil.

[0004]

However, since the processing of trunks and branches after pruning is frequently performed in large orchards and gardens, a large number of humans collect the cut stems and branches. It is necessary to work to collect or collect relatively large trunks and branches after making them large enough to handle. For this reason, it takes a lot of time to collect trunks and branches, and when transporting for incineration, excessive time and labor are required. Even with the use of air scissors, this would require labor to move through large orchards and gardens. In recent years, regulations on environmental protection, such as smoke from incineration, have become strict near residential areas, and in cases where wood chips cannot be incinerated, pruned trunks and branches will be crushed by a crusher. . However, preparing the air scissors and the crusher separately and performing the work while moving in the orchard or the garden increases the equipment cost and requires an excessive amount of time and labor. In addition, since there is a possibility that pests may be mixed in the chip-like fragments pulverized by the pulverizer, there is a demand that the chip-like fragments are to be sown in a field or to be laid on a grassland after fumigation, and furthermore. This will require securing a treatment plant and making capital investment.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art and to reduce the labor and efficiency of pruning trunks and branches regardless of the location and to efficiently pulverize them. An object of the present invention is to provide a riding crusher that contributes to environmental protection.
