Description

[Detailed description of the invention] [Industrial application field]

This invention relates to a fumarole type soil improvement compound working machine,
More specifically, in addition to cutting into the soil with a beam, a fumarole chisel moves deep into the soil and blows out air to activate the soil. The present invention relates to a fumarole-type soil improvement compound working machine that extends the conduction distance and connects a second working machine to the working machine to perform a second work.

[Conventional technology]

In the conventionally known fumarole-type soil improvement work equipment, a compressor is mounted on the frame that constitutes the work equipment, and a beam with a subsoiler function is attached to the cross frame of the work equipment frame, and the lower end of the beam is attached to the cross frame of the work equipment frame. A chisel with a fumarole function is installed in the soil, and the compressed air from the compressor is ejected from the fumarole of the chisel through an air tank to forcibly supply air into the soil, thereby activating the soil. This is what I did. For example, what is shown in Japanese Unexamined Patent Publication No. 55-16176 can be mentioned as a prior example. Additionally, in order to facilitate the cutting of the soil by the beam, a rolling coulter is installed in the vertical plane containing the beam and in front of the beam.

[Problems to be solved by the invention]

The above-mentioned fumarole-type soil improvement work machines are limited to performing so-called soil improvement work, which is to supply air into the soil to activate the soil. Therefore, the only work that can be completed in one trip to the field is soil improvement work; in order to supply chemicals, soil conditioners, fertilize, etc., another work machine must be used to perform the work and travel again. Especially,
In the case of a lawn surface on a golf course, the more the number of times a working machine travels, the more the degree of damage to the lawn increases. Furthermore, since the chemical solution is injected into the soil that has been compacted by another working machine, the sprayed chemical solution does not spread over a wide range of soil, but tends to concentrate and remain in a part of the soil. Therefore, the effect of drug injection cannot be sufficiently obtained. The present invention was devised to solve such problems, and by arranging a chemical liquid discharge pipe immediately after a beam equipped with a fumarole chisel at the lower end,
To efficiently inject a chemical solution into swollen and soft soil that has been aerated without compacting the soil more than necessary.
