Description

[Detailed Description of the Invention] The present invention relates to a chemical spray rate in which a nozzle for injecting a chemical that penetrates into the ground and a roller that presses the ground where the chemical is injected are attached to a vehicle body.

At the above chemical spraying rate, in order to easily perform turning travel, it is necessary to enable the nozzle to change between an injection position and a non-injection position located on the ground;
In addition, in order to change the injection depth of the chemical, it is necessary to be able to change the underground penetration depth of the nozzle, but it is necessary to have the nozzle itself have both the functions of changing the attitude and changing the penetration depth. The nozzle structure becomes complicated.

In view of the above-mentioned circumstances, the present invention is designed to simplify the nozzle structure while also making it easier to perform the turning movement Y''j and changing the injection depth of the drug. Yo (
The purpose is to rub.

In the above-mentioned chemical dispensing vehicle, the nozzle is pivotally attached to the machine frame on a horizontal transverse axis )'I so that it can swing vertically, and the tip of the nozzle i plunges into the ground. position and position on the ground.') The roller is configured to be able to change its position freely on the non-injection position, and the roller is attached to the machine via a height position changing mechanism, so that the roller is positioned relative to the machine frame. It is characterized in that the relative height 711 position is configured to be freely changeable.

In other words, by changing the vertical position of the roller, the nozzle's penetration depth into the ground can be changed, and since the nozzle itself has only the posture change function, it has both posture change and penetration depth change functions. Although the nozzle structure is simpler than when the nozzle itself is provided with the nozzle, the nozzle can be positioned above the ground, making it easier to turn around, and the depth of the nozzle's penetration into the ground can be changed. This made it possible to change the injection depth of the drug.

Examples of the drug distribution rate of the present invention will be described below with reference to the drawings.

A machine frame 3 that can be connected and separated by inserting and removing a connecting pin 2 is extended from the rear of a towing vehicle body 1 equipped with a pair of left and right drive wheels 6, 6, and a plurality of underground protruding claws 4 are provided at both left and right ends. . . . idle rollers 5 arranged in parallel in the circumferential direction, a drug injection nozzle 7 comprising a drug ejection lower C disposed on the back of a cylindrical body 7b equipped with a digging blade 7a, and a tank. A pump 9 is attached to the machine frame 3 for ejecting the medicine stored in the nozzle 7 at the nozzle 7.

Towing vehicle body 1 with injection nozzle 7 plunged into the ground
As the vehicle runs, the roller 5 pulled by the vehicle body 1 is rotated by the action of the underground plunger claw 4, and the roller 5 is
The pump 9 is intermittently driven by a link 11 that is intermittently swung by the rotation of the roller 5, and the medicine is injected into the ground at a predetermined pitch. The structure is such that the traces of the drug are pressed against the groove 12 formed by the excavating blade 7a, thereby preventing the drug from spreading into the air.

As shown in FIG. 2, the nozzle 7 is configured to be able to swing up and down around the horizontal horizontal axis 4, and an unstable switching spring 13 is stretched between the machine frame 3 side and the nozzle 7 side, and the lever 14 is When the direction of the urging force of the spunong 13 is reversed by a swinging operation to the direction in which the nozzle 7 is placed in a downward position, the nozzle 7 is placed in the injection position, and the direction of the urging force is changed in the direction in which the nozzle 7 is placed in a position along the longitudinal direction of the vehicle body. In this case, the nozzle 7 is placed in a non-injecting position above the ground, and when the vehicle turns, the nozzle 7 is raised above the ground by operating the lever 14.

As shown in FIG. 3, the roller 5 is attached to the rear of the machine frame 3 via a height position changing mechanism A, and when changing the injection depth of the drug, the height position is changed. The mechanism A is configured to change the fixing position of the roller 5 with respect to the vehicle body 1 to change the underground penetration depth of the nozzle 7.

The height position changing mechanism A is connected to the rear end of the machine frame 3 and the roller 5.
The support rod 15 of the tank 8 passes through the cylindrical portions 3a, 10a formed at the front end of the arm 10, which is pivotally connected to both ends of the rotation shaft 5A, and the two cylindrical portions 3a, 10a.
and bolts 16, 17 attached to each cylindrical portion 3a, 10a, respectively, and by tightening the bolts 16, 17... 16.17 Fix the vertical height position of
By loosening the rollers 5, the vertical height position of the roller 5 can be freely adjusted.

To mount the tank 8, as shown in FIG. 4, it is mounted on the front of the towing vehicle body 1, and the tank 8 is movable in the front and back direction, so that the tank 8 can be moved in the front and rear directions according to the weight change due to the consumption of the drug in the tank. Alternatively, the tank 8 may be slid together with the tank support frame 19 along the tank mounting base 18 to stabilize the balance of the vehicle.

Further, in this case, the tank mounting base 18 itself may be of a drive telescoping type, and the tank 8 may be moved by its telescoping operation.
