Description

[Detailed Description of the Invention] The present invention relates to a soil disinfection machine for exterminating pests such as nematodes that live in the soil of farmland, for example.

That is, the gist of the present proposal is to provide a movable body, a nozzle body operating means connected to a drive means of the body,
The nozzle body is reciprocated by the nozzle body operating means in a direction substantially perpendicular to the traveling direction of the body and inserted into the soil,
and two nozzle bodies inserted alternately into the soil at different locations on the left and right with respect to the traveling direction of the aircraft, a chemical tank connected to these nozzle bodies via appropriate pipe bodies, and the nozzle bodies reciprocating. and a drug supply means for supplying the drug in the drug tank to the nozzle body when the machine reaches a predetermined position, and the two nozzle bodies are moved alternately as the machine moves. It is inserted into the soil and sprays the chemical in a staggered manner.The effects of staggered driving in this way are: (1) Compared to simultaneous driving, the driving reaction force is smaller, there is less shaking of the machine, and it is easier to drive. A device that maintains uniformity of disinfection by keeping the angle and depth of implantation constant.

(2) It is possible to sterilize evenly with less wasteful overlap of permeation area and less permeation residue.

Next, an embodiment of the present invention will be described with reference to the drawings.

In the figure, 1 is the fuselage, 2 is the driving means of the fuselage 1, 3°3' is the wheels, 4, 4' are the nozzle bodies, 5 is the nozzle body operating means, 6 is the drug tank, and 7 is the nozzle bodies 4, 4'. The pump is disposed in a conduit 8 connecting the drug tank 6 and the nozzle body 4, and only the nozzle body 4 is shown in the drawing.

The nozzle body actuating means 5 includes two crankshafts lL connected via a transmission mechanism (not shown) such as a gear or a chain.
12, and a case 1 comprising these crankshafts lL12.
0, and cranks 13, 13', 14, 14' attached to both ends of each crankshaft lL12, the case 10 is swingably attached to the front end of the fuselage 1, and the crankshafts 11, 12 One of them is connected to the drive means 2 via a transmission mechanism (not shown).

Further, cranks 13 and 14 of the cranks mounted on the same side of both crankshafts 11 and 12 pivotally support the nozzle body 4,
13' and 14' pivotally support the nozzle body 4'.

A cam 9 is provided on the crankshaft 12 or 12', and the nozzle bodies 4, 4' are reciprocated by the nozzle body operating means 5 to rotate the crankshaft 13°13', 14, 14.
When the nozzle body 4.4' reaches its lowest point at the bottom dead center of the movement of ', the cam 9 presses the piston shaft 7' of the pump 7 to operate the pump 7. .

The timing at which this cam 9 operates the pump 7 is as follows.
It is not necessarily the time when the nozzle bodies 4, 4' reach the lowest point, but an appropriate time can be selected.

The proposed soil disinfection machine configured as described above has a machine body 1.
The crankshaft 11.12 rotates with zero travel, and the nozzle body 4 is rotated through the crank 13.14.
A reciprocating motion is applied to the nozzle body 4' through the nozzle 4' and 14'.

In this case, the nozzle bodies 4 and 4' are attached by cranks displaced by 180 degrees, so that they are inserted alternately into the soil as shown in FIG.

The nozzle body 4 is inserted into the soil 24 in the state shown in FIG. 4 (■), and the nozzle body 4' is inserted into the soil 24 in the state shown in FIG. 7 is activated to spray the chemical into the soil 24 from the nozzle bodies 4, 4'.

Moreover, if the nozzle body 4 is set so that it can be inserted into the soil 24 between ① and IV, and the nozzle body 4' is set so that it can be inserted into the soil 24 between tv and tr,
The chemical agent can be sprayed without moving the position of the nozzle bodies 4, 4' inserted into the soil 24 while the machine body 10 is running.

On the other hand, the soil disinfection machine of the present invention is provided with a switching means for switching the nozzle body operating means 5 between a use position and a non-use position.

That is, the link 16 is attached to the first swinging arm 15' of the bell crank 15, which is pivotably mounted on the upper end of the front side of the fuselage 1.
A nozzle body includes a protrusion 18 which is pivotally connected at one end and movably connected to the link 16 via a slidable pin 17 inserted into an elongated portion 16' provided at the other end of the link 16. The actuating means 50 is fixed to the case 10, and the second swinging arm 15 of the old bell crank 15 has a connecting rod 19.
The operating swing lever 20 is connected to the operating swing lever 20 via the operating swing lever 20, and the swing lever 20 is swingably attached to the operating handle 1'l: of the machine body 1.

Further, a second link 21 whose one end is pivotally connected to the link 16
A stopper claw body 22 having one end pivotally connected to the other end and having a claw portion 22' at the other end is swingably attached to the lower end of the case 10, and in the use position shown in FIG.
A stopper 23 with a stopper claw body 22 provided on the machine body 1
In other words, the claw portion 22' is engaged with the stopper 23.

When the operating swing lever 20 is displaced from the state shown in FIG. 1 to the state shown in FIG. is removed from the stop flange 23, and the case 10, that is, the nozzle body operating means 5 and the nozzle bodies 4, 4' are switched to the non-use position via the projection 18 connected to the link 16.

Therefore, the soil disinfection machine of the present invention can be easily transported before and after work.

Therefore, according to the present invention, soil disinfection can be performed efficiently without damaging the nozzle body.
