If you use a two-wheeled or four-wheeled vehicle with a wide width, it is easy to move, but if the valley of the field is narrow, it can not be put inside. It is necessary to work with long hoses with nozzles, in each case not only high power is required, but also the inability to spray on the back of the leaves of the crop and the hose may cause crop damage. Was.

However, there is a problem that not only is the production cost high, but also because it is difficult to maintain a balance when moving due to its height and stability. 63-2780
No. 4, Japanese Utility Model Publication 3-1084, Japanese Utility Model Publication 4-41
In the case of the sprayer described in Japanese Patent No. 960, the center of gravity is high and unstable because the chemical solution tank and the like are placed on the wheels, the work is difficult, and the structure is complicated, and the manufacturing cost is low. Get higher. In the case of a structure in which a pair of stationary legs are provided at the rear portion as in the sprayer described in Japanese Utility Model Publication No. 4-41960, the sprayer is stopped in a narrow place such as a ridge because it is wider than the wheels. There is also the problem that you cannot do that.

に吸い付き、吸水できなくなる場合もある。In addition to the above-mentioned problems, in a chemical spraying vehicle, it is necessary to use up the chemical supplied in a chemical tank provided on the vehicle body without leaving it. Was difficult. That is, the suction pipe is hung down in the chemical liquid tank, and the water suction port at the tip of the suction pipe is placed sideways on the bottom of the tank, or the tip is cut obliquely and placed on the bottom of the tank, and the chemical is sucked by the pump. With this structure, when the remaining liquid is low, it is difficult to suck up to the end, and air may enter the suction pipe due to the inclination of the tank or the liquid shakes, and the suction force of the pump may be lost. Battery is running high. In this way, when the remaining amount of the chemical solution increases, not only does it take time to clean the tank, but also
There is a problem that the remaining pesticide is mixed with another pesticide to be used next time and harms the crop. Furthermore, since the suction tube is placed on the bottom surface of the tank in the tank, the tip of the suction tube may stick to the bottom surface or the side surface of the tank due to the inclination of the tank, the vibration of the pump, and the suction pressure of the suction tube, and the water may not be absorbed.

破損する問題がある。Further, in a chemical spraying vehicle which travels in a valley of a ridge of a field of this kind, soil and mud tend to adhere to wheels, and it is necessary to scrape off the adhered soil and mud. Conventionally, as a scraper for scraping these soils and mud, FIG.
(A) As shown in (B), a long iron plate A and a round bar B are arranged in parallel with the rotation axis Wa of the wheel W. However, in the scraper made of an iron plate or a round bar arranged in parallel with the rotation axis, when the soil or mud attached to the wheel increases, a large force is applied to the scraper, and there is a problem that the scraper is damaged.

がかかる問題がある。Further, in a chemical spraying vehicle, an operator generally grips a hose communicating with a chemical tank and sprays a chemical from a nozzle attached to the end of the hose. Therefore, it is necessary for the worker to spray the chemical solution with the hose while running the chemical spray vehicle by hand,
When the tank capacity is large and the vehicle body is heavy due to the chemical solution stored in the tank, the burden on the operator increases. In addition, when it is necessary to spray the chemical solution on the crops on both ridges, the chemical solution must be sprayed on the crops on one ridge, and then the chemical solution must be sprayed on the crops on the other ridge. There is a problem of burden.

By increasing the length in the circumferential direction, the scraping effect can be enhanced. Further, if the pins of the scraper are arranged in a staggered manner (ie, spaced in the axle direction and spaced in the circumferential direction), the time for the pins to hit the soil or mud is shifted, and the load on the pins can be further reduced. The ratio of the scraper pins to the wheel width occupied by the pins is preferably about 20%.
Soil and mud adhering to the entire outer peripheral surface of the wheel can be reliably scraped off.

Since the suction tube sandwiched by the suction tube holding groove is opened with respect to this depression, the suction tube can be almost completely sucked into the suction tube without remaining liquid in the tank. In particular, the water suction port at the end of the suction pipe is floated in the recess, and the bottom of the tank does not touch the side surface. In addition, the pump can be prevented from being damaged. Further, since the residual liquid can be eliminated, the tank can be easily washed, and it is possible to prevent the chemical spray from being mixed with the agricultural chemical to be used next time and causing chemical damage to the crops to which the chemical liquid is applied.

Since the vehicle is arranged adjacent to the center position in the width direction of the vehicle body 2, the vehicle can travel freely in narrow valleys between ridges without increasing the vehicle width while using two traveling wheels. In addition, since the vehicle is a two-wheeled vehicle, the problem of the left and right balance, which has been a problem with unicycles, can be solved. Further, since the two wheels can be independently rotated, a very small curvature can be obtained, and the direction can be easily turned between the narrow ridge valleys.

きる。Further, since a plurality of pins 14 are used to scrape off dirt and mud adhering to the outer peripheral surface of the traveling wheel, the load on the scraper when scraping dirt and mud can be reduced. In particular, since the cross-sectional shape of the pin 14 is an elliptical shape that is long in the circumferential direction, the load applied to the pin 14 can be further reduced, and the effect of scraping off can be enhanced by being long in the circumferential direction. Further, the staggered arrangement shifts the position at which the pin 14 hits the soil or mud, thereby further reducing the load applied to the pin 14. When running in the valley between the ridges, a large amount of mud adheres to the outer peripheral surface of the wheel. However, as described above, the scraper is fixed to the vehicle body 2 by using the pin 14 and the strength is large. In a zigzag arrangement, a large amount of soil and mud adhering to the outer peripheral surface of the wheel can be reliably scraped off.

ことも防止できる。On the other hand, also with respect to the suction of the chemical solution 9 from the chemical solution tank 8, the chemical solution 9 will eventually accumulate in the recess 8d because the bottom surface 8a of the chemical solution tank 8 is inclined. Since the liquid suction tube 15 sandwiched by the suction tube holding groove 8e is opened to the recess 8d, the liquid suction tube 15 can be almost completely sucked into the liquid suction tube 15 without leaving any remaining liquid in the liquid medicine tank 8. . In particular, the chemical suction tube 15
The water-absorbing port 15a at the tip of the container is floated in the recess 8d and does not touch the bottom surface or side surface of the chemical liquid tank 8, so that it is possible to prevent the liquid from sticking to the bottom surface or side surface. Without interruption, and chemical pump 8
It can also prevent harm. Further, since the rib 8b is provided so as to surround the recess 8d, even if the vehicle body is tilted, the chemical solution in the rib 8b can be prevented from jumping out, and the remaining liquid is stored in the rib 8b, and finally the recess 8d is formed. Can be stored in
As described above, since the residual liquid can be eliminated, the cleaning of the chemical liquid tank 8 is simplified, and it is also possible to prevent the chemical spray from being mixed with the agricultural chemical to be used next time and causing chemical damage to the crops to which the chemical liquid is applied.
