Description

[Detailed description of the invention] Industrial applications The present invention is applied to the cultivation process of crops such as tobacco.

This invention relates to a chemical spraying device that drops and sprays chemical solutions from above the trunks of crops.

BACKGROUND OF THE INVENTION Conventionally, in the cultivation of tobacco, the upper part of the tobacco trunk is cut off to prevent the trunk from growing upward. By coring, the number of leaves to be harvested is determined, sufficient nutrients are supplied to the leaves to be harvested, and the yield and quality are improved.

However, even if the core is fixed, if debris sprouts from the root portion of the leaf, sufficient nutrients cannot be supplied to the leaves to be harvested. Therefore, the occurrence of axillary buds is prevented by spraying an axillary bud inhibitor. here,
In the past, systemic transfer-type axillary bud inhibitors were widely used, which were sprayed over the entire tobacco leaf surface after the tobacco was cored, but in recent years, contact-type axillary bud inhibitors have become popular. It's starting to grow.

This contact-type axillary bud suppressant cannot suppress axillary buds unless it attaches to the root part of the leaf where axillary buds emerge, so it must flow down the stem. Currently, this contact-type axillary bud inhibitor is sprayed by a worker carrying a chemical tank containing the chemical solution on his back, walking along the furrows and manually applying it to each tobacco plant. .

Problems to be Solved by the Invention Spraying an axillary bud suppressant while carrying a chemical solution tank on one's back is very hard work, and the work efficiency is poor and requires a long time. Furthermore, when spraying an axillary bud inhibitor, care must be taken to ensure that the axillary bud inhibitor does not adhere to the growing leaves, but when spraying is done while looking up from diagonally downwards, it is important to spray precisely at the center of the trunk. This is difficult and becomes even more difficult as worker fatigue increases.

Means for Solving the Problem A mobile agricultural machine having a chemical liquid tank containing a chemical liquid and traveling between the furrows is provided, and a chemical liquid dispersing arm connected to the chemical liquid tank via a power pump and having a spot nozzle is moved. Installed on agricultural machinery.

The operator moves the mobile agricultural machine along the furrow where crops are planted, and brings the spot nozzle of the chemical spraying arm above the trunk of the crop to perform spot-type chemical spraying.

Example An embodiment of the present invention will be described based on the drawings.

First, a mobile agricultural machine 1 is provided that travels between furrows where crops such as tobacco are planted. Chassis 2 of the mobile agricultural machine 1
An engine 3 is mounted on the front part of the vehicle, and a transmission case 4 is fixed thereto.

Furthermore, a drive pump 5 is mounted on the chassis 2 at the rear of the mission case 4, and a chemical solution dispersion column 6 is erected. Also.

At the rear of the chassis 2, a chemical solution tank 7 containing a medicinal axillary bud suppressant is placed.

An output pulley 9 is fixed to the output shaft 8 of the engine 3, and an input shaft 1 is fixed to the output shaft 8 of the engine 3.
The input pulley 11 is fixed to 0, and these pulleys 9,
A V-belt 12 is wound between the belts 11 and 11. Further, an output pulley 14 is fixed to an output shaft 13 provided at the upper part of the mission case 4, an input pulley 16 is fixed to an input shaft 15 of the drive pump 5, and these pulleys 1
A V-belt 17 is wound between 4° and 16°. A tension roller 18 that intermittently applies tension to the V-belt 12 and a tension roller 19 that intermittently applies tension to the V-belt 17 are attached to the outer wall of the mission case 4. Further, a drive shaft 20 is provided at the lower end of the transmission case 4, and a drive wheel 21 is connected to the drive shaft 18.

Next, the chemical liquid tank 7 and the driving pump 5 are connected by a piping hose (not shown), and the driving pump 5 and the socket 22 provided at the upper part of the chemical liquid dispersing column 6 are connected to each other by a piping hose (not shown). Connected by a hose (not shown). Immediately before the socket 22 of the hose, a cock 23 is provided to cut off the flow of the armpit bud suppressant, and one end of the chemical spraying arm 24 is connected to the socket 22.
5. A spot nozzle 26 is provided at the other end of the chemical solution dispersing arm 24, and a bush type cock 28 is provided adjacent to the grip portion 27 of the chemical solution dispersing arm 24.
is provided.

Note that a driven wheel 29 is rotatably connected to the rear portion of the chassis 2. Furthermore, an operating section 30 is provided at the rear end of the chassis 2, in which an accelerator lever, a change lever, a clutch lever, a stop switch, etc. are arranged.

In such a configuration, when performing the spraying work of the side bud inhibitor, the mobile agricultural machine 1 is positioned in the furrow where tobacco is growing as shown in Fig. 3, and the mobile agricultural machine 1 is moved at a slow speed in the direction of arrow a. Run it with Further, the driving pump 5 is actuated by the driving force from the engine 3, and the axillary bud suppressant in the chemical solution tank 7 is force-fed to the cock 23 through the hose. In addition,
The mobile agricultural machine 1 has left and right drive shafts 21 guided by ridges on both sides, and moves straight along the ridges without any steering operation.

On the other hand, the operator grasps the grip part 27 of the chemical liquid spraying arm 24 and walks while being positioned behind the mobile agricultural machine 1. Then, by bringing the spot nozzle 26 close to the upper part of the tobacco stem and opening and closing the bush type cock 28, the side bud inhibitor is sprayed onto the upper end of the tobacco stem. The side bud inhibitor sprayed on the upper end of the tobacco stem flows down along the stem.
The leaf attachment is attached to the part of the root where lateral buds occur. and.

As the mobile agricultural machine 1 advances, the side bud inhibitor is sequentially sprayed on the tobacco lined up.

Here, the operator only has to walk behind the mobile agricultural machine 1 and operate the chemical solution spraying arm 24, and the labor required for spraying the side bud inhibitor is greatly reduced. For this reason, the spot nozzle 26 can be positioned at the top of the tobacco stem, and the work of opening and closing the bush type cock 2.6 can be done with plenty of time.
It is possible to easily prevent the axillary bud inhibitor from adhering to tobacco leaves.

In addition, since the operator adjusts the position of the spot nozzle 26 while observing the condition of the tobacco stem, the top end of the tobacco stem may vary in height, or the tobacco stem may grow at an angle. Even if there is a bud, the axillary bud inhibitor can be sprayed reliably at the upper end of the trunk. Furthermore, it is possible to reliably prevent the omission of spraying of the axillary bud inhibitor. Furthermore, since it is a spot spraying method, workers are prevented from getting sprayed with the side bud inhibitor.

Although this embodiment has been explained using a dedicated machine for spraying chemical liquid as the mobile agricultural machine 1, it is also possible to use an elevated type working machine that is equipped with a chemical tank, a drive pump, a chemical spraying arm, etc. and steers it across a tiller or crops. It may also be connected to a work vehicle, etc.

Furthermore, although this embodiment has been described using an example in which one chemical solution dispersing arm 24 is provided, the work efficiency can be improved by providing two chemical solution dispersing arms 24.

Effects of the Invention As mentioned above, the present invention greatly reduces the labor required for the work by attaching heavy chemical tanks and power pumps to mobile agricultural machinery and allowing one worker to spray the chemical by operating the chemical spraying arm. In addition, since the work efficiency is reduced, the chemical solution can be sprayed accurately to the central part of the trunk of the crop by operating the chemical solution spraying arm. , workers operate the chemical spray arm to position the spot nozzle while checking the growth status of the crop, so even if the position of the upper end of the trunk varies in height or in the left/right direction, A contact-type side bud control that can accurately spray the chemical solution to the central area, prevent the chemical solution from being applied to leaves other than the trunk, and prevent the generation of tobacco side buds as a chemical solution. It has the effect of increasing the yield by spraying the agent.
