Abstract

The present invention relates to a chemical spreader for a rice planting machine which operates smoothly. More particularly, the present invention relates to a novel concept of preventing the chemical from being stuck to a sliding gate for opening and closing a chemical passage to smoothly operate the chemical spreader, and uniformly spreading the chemical in proportion to the traveling speed of the rice planting machine. The conventional chemical spreader hinders the smooth linear movement of the sliding gate, so that the operability is remarkably lowered, the operation load of the automatic chemical supply control valve is caused, the chemical spreader has to be cleaned from time to time, and the chemical cannot be spread according to the moving speed of the mounting board. In order to solve the problem, the present invention prevents the chemical from being loaded on an upper surface of the sliding gate while smoothly opening/closing the chemical passage of the chemical supply housing. The operating cycle of the gate opening/closing valve can be precisely controlled in proportion to the traveling speed of the rice planting machine through a method of detecting the lateral moving speed of a sensor dog attached to a rear surface of the mounting plate support by a proximity sensor fixed to the body pipe of the rice planting machine.

Description

[0001] The present invention relates to a chemical applicator for rice transplanter,

The present invention relates to a novel concept of preventing a medicine from sticking to a sliding gate for opening and closing a medicine passage to smooth the operation of the medicine spreader and uniformly distributing the medicine in proportion to the traveling speed of the rice mill.

In general, the weed occurrence in the rice germination plant is higher than that in the transplantation rice plant. As the period from harrow to harvest is longer, the use time of the herbicide used before germination is inadequate. Weeds, spruce, spruce, and bamboos are more common, and there are many days until the community formation period, and the water is shallow enough to provide a good condition for weeding.

The most obvious and least costly way to control these weeds is to use herbicides, and the range of weed control varies depending on the type of herbicide.

In particular, since migrant seedlings are susceptible to aging, it is preferable to use a highly selective herbicide which does not damage the rice as much as possible, but also does not pollute the environment.

Treatment with these herbicides should be carried out using an initial treatment agent at about 5 to 8 days after transplanting, using a medium treatment agent at about 15 to 20 days, and using a wet treatment herbicide from the effective seeding stage to the water distillation stage.

Herbicides treated at about 5 to 8 days after transplanting as described above are mainly used for spraying the mouth-type herbicide for soil treatment, or using a power sprayer as a part thereof.

However, since the herbicide of this mouth-type is small and the amount of spraying is relatively small as 1 to 3 kg per acre, it is very difficult to uniformly spray an appropriate amount of the herbicide uniformly. If already sprayed, the area is visually confirmed and identified And it is difficult to suitably adjust the application amount.

These problems cause overlapping and overspraying of the herbicide-type herbicide, which causes not only rice but also environmental pollution due to increased water quality and soil pollution.

In addition, even if it is sprayed manually by manpower or sprayed using a power sprayer, it is necessary to spray it inside the rice paddy, so that the footprints of the rice paddy that occurs during transportation cause damages to the hair, , It has a problem that it has a direct effect on the human body, so that the herbicide is sprayed simultaneously with the machine transfer using the herbicidal spraying device mounted on the flyer.

As a prior art capable of spraying the herbicidal granule at the same time as the transfer of the herbicidal granule, there is disclosed " Patent Registration No. 1628293 entitled " Free Falling Medicinal Product Sprayer for rice planting " filed by the applicant of the present invention.

The above-mentioned prior art is installed in the pasture stage to smoothly spray the medicine on the base plate in a free-fall manner while preventing the adhesion of the medicine. When the sliding gate that blocks the lower side of the medicine passage is temporarily opened while moving horizontally, So as to be sprayed to the outside.

However, since the sliding gate is horizontally moved while some of the drugs stacked on the upper surface are horizontally moved together with the gap between the sliding gate and the gate aperture, the sliding gate is fixed as time passes, thereby preventing smooth linear motion of the sliding gate, And the operation load of the automatic medicine supply control valve is caused, and it is troublesome to clean the medicine supply automatic control valve from time to time.

In addition, in the pasture stage, the mount plate on which the mother liquor is mounted moves reciprocally while moving in parallel with the traveling speed, and spraying the agent in accordance with the moving speed of the mount plate prevents the overspray or underspray of the drug, There is no technology to solve this problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a sliding gate which linearly moves in an oblique direction smoothly opens and closes a drug passage of a drug supply housing, I will try.

In addition, the present invention provides a method of detecting a moving speed of a gate opening / closing valve in proportion to a traveling speed of a sewing machine, by detecting a moving speed of a sensor dog attached to a rear surface of a mounting plate support, Precise control can be achieved.

According to the present invention, since the sliding gate directly connected to the gate opening / closing valve is disposed in an oblique direction, when the sliding gate is opened while being moved in an oblique direction, the medicine placed on the upper surface is prevented from flowing down along the slope, It is possible to improve the operability of the sliding gate significantly by preventing the medicine from being caught or fixed in the gap between the gate through-holes, to improve the durability by eliminating the operation load of the gate opening / closing valve and eliminating the trouble of separating and cleaning the medicine supply housing Management is very easy.

Further, according to the present invention, the operating speed of the gate opening / closing valve is accurately controlled in proportion to the traveling speed of the moving machine by driving the gate opening / closing valve in accordance with the moving speed of the mounting plate moving reciprocally in the left / It is possible to spray the medicines uniformly at all times and to reduce the excessive use of the medicines, thereby preventing soil and water pollution.
