[0002]

2. Description of the Related Art Conventionally, a technique for mounting a soil disinfecting machine behind a traveling vehicle such as a tractor has been publicly known. For example,
As disclosed in JP-A-5-199828,
A soil disinfecting machine was attached to the rear of the traveling vehicle through the top link and the lower link. The soil disinfecting machine is configured such that a chemical solution supply member such as a chemical solution pump or a chemical solution tank and a subsoiler are arranged on a frame. In this soil disinfecting machine, when fixing the nozzle to the sub-soiler, a hole dedicated to mounting was separately provided or integrally provided.

[0003]

However, the soil disinfecting machine does not work by using only the subsoiler, and neither the chemical solution pump nor the chemical solution tank is attached to another working machine, and the dedicated soil is used. If it is a disinfection machine and is expensive and has a sub-soiler or a towing type working machine, you will have two working machines that perform the same function and purchased an extra working machine. I feel it. In addition, a storage location is also required separately. Also, since it was a dedicated machine, it was difficult to remove or replace only the chemical pump.

[0004]

The problem to be solved by the present invention is as described above, and the means for solving this problem will be described below.

That is, according to the first aspect of the present invention, a chemical solution supply member including a chemical solution tank, a chemical solution delivery pump and the like is attached to the tool bar, the tool bar is provided with an attachment member, and the attachment member is detachably attached to the mast portion of the working machine. It is composed.

According to a second aspect of the present invention, the tool bar is arranged in the left-right direction with respect to the machine body, and the chemical liquid supply member is arranged on the tool bar so as to be laterally distributed.

According to a third aspect of the present invention, the nozzle of the soil disinfecting machine is attached to a nozzle holder, and the nozzle holder has a shape adapted to the rear surface shape of the subsoiler.
It is fixed to a hole opened on the side surface of the subsoiler via a mounting plate.
