Description

[Detailed description of the invention] Industrial applications The second invention relates to a chemical spraying device for a pest control machine.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION In a pest control machine that is equipped with a horizontally long boom having an appropriate number of nozzles for spraying a chemical solution on a traveling vehicle body, it is difficult to spray the chemical solution especially along the contour lines of a slope. When carrying out work, the vehicle body tends to tilt further down the slope with respect to the surface of the slope, and as the vehicle body tilts, the boom cannot be kept parallel to the ground, so the position of each nozzle is The spray may be placed too close to or too far from the crop, resulting in uneven distribution.

Means for Solving the Problems This invention utilizes an appropriate number of nozzles 1°1...
A chemical solution spraying device of a pest control machine is constructed in which a boom 2 arranged in the left and right direction is rotatably adjusted in the vertical direction with respect to the traveling vehicle body 3.

Effect of the Invention The left-right boom 2 having the respective nozzles 1, 1, . . . is rotatably adjusted in the vertical direction relative to the vehicle body 3.

Effects of the Invention Even if the traveling vehicle body 3 is tilted in the left-right direction with respect to the ground surface, it is possible to rotate the boom 2 in the left-right direction vertically with respect to the traveling vehicle body 3 to align the boom 2 with the ground surface. Therefore, the positions of the nozzles 1, 1, . . . are not too close to or too far from the crops to be sprayed, and therefore the spraying state to the crops to be sprayed can be made uniform.

Example: On the park side, a pair of left and right front wheels 5, 5 and rear wheels 6, 6
A prime mover 8 whose upper and front sides are covered with a bonnet 7 is provided at the front of a running vehicle body 3 which is equipped with an axle.A handle 9 is provided at the rear end of the bonnet 7 to interlock the steering with the front wheels 5.
is installed diagonally, and a chemical liquid tank 10 for storing a chemical liquid is mounted on the rear part of the traveling vehicle body 3, with a driver's seat part 10a formed in the front part.

A frame 11 that protrudes forward is provided on the front side of the prime mover 8, and a shaft bearing part 12 having a shaft bearing part 12a located on the frame 11 in the longitudinal direction is bolted to the front end of the frame 11. The shaft bearing part 12a is rotatably provided with a rotating shaft 13 having a protrusion 13a protruding from the rear end of the shaft bearing part 12a. A pair of front and rear arms 14 . A hydraulic cylinder 16 is provided for rotating said arm 14.14.

Further, at the front end of the rotation shaft 13, pillars 1.
7.17 and connect the support 18 with the strut 17.1
7, there is a support member 19a in the center in the left and right direction.
Both left and right ends of the support plate 19 having
0, and the lower end of this boom support rod 20 is connected to the base of a boom 2 that is long in the left-right direction and has an appropriate number of nozzles 1, 1, . . . arranged thereon for spraying a chemical solution.

Note that 2a and 2b are reinforcing members that reinforce and support the boom 2;
1 is an operating lever that operates the hydraulic cylinder 16 to extend and retract.
A pump 22 pumps the chemical liquid in the chemical liquid tank 10 to each nozzle 1 through a hose (not shown).

Next, the effect will be explained. The chemical liquid in the chemical liquid tank 10 is fed under pressure through the pump 22 and the hose to the nozzles 1, 1, . . .
・It is injected from.

When the hydraulic cylinder 16 is expanded or contracted by operating the operating lever 21, the hydraulic cylinder 16 is expanded or contracted through the arms 14, 14, the rotation shaft 13, the support body 18 and the struts 17 and 17, as well as the support plate 19, the support member 19a and the boom support rod 20. The boom 2 and reinforcing members 2a, 2b are rotated downward or upward.

4 and 5 show another embodiment, in which the frame 1
1 is provided with a left-right fixed boom 25 having the nozzles 1, 1, . A support member 27 having a bottle 26 is provided, and on the left side of this support member 27, a support member 27a rotatably supported by the support bottle 26 and the nozzles 1, 1 supported by this support member 27a are provided. A rotating boom 28 having... is provided.

At the center of the fixed boom 25, there is a roller 2 at the upper end.
9 and the roller 29a below this roller 29 are erected, and at the rear of the bonnet 7, the chemical liquid from the pump 22 is pumped to each nozzle 1, 1... Alternatively, a switching valve 31 that stops is provided, and this switching valve 31 is provided with a swing switching lever 32 that operates the switching valve 31 to the stop side by rotating backward.
2 and the tip of the rotating boom 28, a wire 33 that is wound around each of the rollers 29a and 29 is stretched.

FIG. 6 shows yet another embodiment, in which a support column 34 is provided upright at the front end of the frame 11, and support bins 34a, 34b in the nautical direction are provided at the upper and lower ends of the support column 34. The upper support bin 34a rotatably supports one end of the hydraulic cylinder 35, and the lower support bin 34b rotatably supports one end of the link 36. The other end of the hydraulic cylinder 35 and the other end of the link 36 are connected to each other.
A boom 37 which is long in the left and right direction and has a vertical connection part 37a that forms a parallel link with the boom 6 and the support column 34 is connected by a pair of upper and lower bins 37b and 37c.

Further, a lifting hydraulic cylinder 38 is provided between the lower support bin 34b and the upper bin 37b, and a vertical sliding hole provided at the tip and intermediate portion of the boom 37 is provided with a hydraulic cylinder 38 for lifting and lowering. The upper parts of both support rods 40 and 40a, which have rollers 39 and 39a that roll on the ground at their lower ends, are slidably provided, and around these support rods 40 and 40a, the support rods 40 and 40a
