Description

[Detailed description of the invention] This invention is an agricultural soil disinfection machine that can be attached as an attachment to an agricultural machine equipped with a rotary tillage device such as an agricultural tractor, and can be used to inject soil disinfection chemicals into cultivated soil at the same time as tilling. This relates to the liquid drug injection device used.

Soil disinfection in conventional farming is done after tilling and leveling the soil.
Regardless of whether it is a dedicated machine or an attachment machine, the universal method is to use a so-called injection sword, which has a straight sword with a pipe for injecting the chemical liquid attached to the back, and inject the chemical liquid while dragging it through the leveled cultivated soil. It was adopted by

In this method, the injection knife is directly pumped into the cultivated soil, so the nozzle, etc. at the tip of the injection section comes into contact with the cultivated soil, which tends to clog the nozzle and cause clogging of the chemical solution.

On the other hand, there were drawbacks such as the traces of the injection knife's trace grooves remaining, which hindered sowing and transplantation in the case of chemical injection, furrowing, multi-work, etc.

The present invention solves the above-mentioned drawbacks by preventing the injection pipe and nozzle from coming into contact with cultivated soil using protective equipment, and by positioning the spraying part of the chemical solution in the soil during rotary tillage.

To explain in detail below with reference to the drawings, the injection fitting consists of a mounting culm 1, support culms 2, 2', a sword 3, and a protective tube 4. Support culms 2, 2' are arranged on both sides of the mounting culm 1, and welding 1, 2, and 2' are fixed together using the method described above, and a gap is created between 2 and 2' so that the injection tube 5 can be inserted therein.

Insert the sword 3 into the tips of the supporting culms 2 and 2' in the same way as the mounting culm 1,
In relation to the rotary tiller, the sword 3 has an appropriate receding angle and is dried by a method such as welding.

The front part of the sword 3 has a blade shape at the front to reduce resistance during plowing, etc., and a hollow protection tube 4 of a size into which an injection tube 5 can be freely inserted is welded to the rear.

The injection pipe 5 is made of a resin pipe or a corrosion-resistant steel pipe.
It has almost the same shape as the injection fitting, and the tip shows the amount of chemical solution,
The mounting position of the protection tube 4 and the nozzle 6 at the tip of the injection tube, in which the nozzle 6 for adjusting the ejection speed etc. is attached, is as shown in Fig. 7, with the tip of the nozzle 6 located further back than the tip of the protection tube 4. Install it in the condition.

Note that the injection tube 5 and the protection tube 4 can also be applied to a straight sword.

The soil disinfectant injection device made in this way is used on tractor A.
The support fitting A5 provided at the rear end of the rotary tilling power bar A4 is mounted in the gap between the rotary tilling claws as close as possible to the rotary shaft A6 using a cross mounting fitting that can be adjusted forward and backward and up and down.

While maintaining this relative position, the tractor wheel A2
When the rotary tilling section A3 and the rotary tilling section A3 rotate at the same time, the wheel A
2, the tilling work is done while the whole is moving forward.

At this time, the cultivated soil b is scattered rearward by the rotating force of the rotary claw, and rises up further rearward than the injection fitting as shown in B2.

In this way, when the chemical injection device of the present invention is attached to the agricultural machine having a rotary tillage section as described above, and the chemical injection work is performed at the same time as rotary tillage, the injection pipe 5 is protected by the protective tube 4. Therefore, there is no clogging of the nozzle as there is no contact with cultivated soil.

In addition, since the area after the chemical solution is injected is covered with the soil scattered by rotary tillage, there is no drag resistance against the injection fittings, and there are excellent effects such as leaving no trajectory grooves of the injection fittings in the tillage traces. Multi-tasking can be done at the same time, and the labor-saving effect is great.
