A liquid medicine sprayer attached to the tractor}

The present invention relates to a tractor-attached chemical liquid control device, and more particularly, the moving wheels provided in the trailer of the chemical liquid control machine coupled to the rear of the tractor are configured to be horizontally rotatable separately from the loading box, and in particular of the axle supporting the two wheels. The vertical rail feeder vertically installed at both ends is made of a structure that can be refracted or diffractive at an angle, and relates to a tractor-attached chemical liquid control device configured to facilitate left, right rotation and movement when towing and working on the tractor.

Conventionally, a number of chemical liquid control devices configured to control pesticides using the power of a tractor in a state of being attached to a tractor have been known and used.

In the case of the conventional tractor-attached chemical liquid dispenser, a chemical container, a spray bottle, a hose reel, and the like are mounted in a loading box of a trailer, and each device mounted in the loading box can drive the sprayer, the hose reel, etc. by the power drawn from the tractor. It is equipped with a power transmission device composed of a power input shaft, a drive and a driven pulley, a belt, and the like to control the chemical liquid stored in the chemical container.

Such a conventional tractor-attached chemical liquid control device is typically provided with one or three connectors in the front of the trailer, as shown in Figures 1 and 2 is configured to be firmly coupled to the tractor towed.

In other words, in the case of a large-capacity chemical liquid control device, various types of control devices including chemical liquid containers are large, and the trailer of the chemical liquid control device is also largely designed, and one connector is provided at the center of the front of the trailer to be combined with the tractor by one point. In the case of a small chemical liquid control device, the trailer consists of a three-point structure having three connectors connected to the tractor at both the front lower side and the upper center of the trailer.

In addition, in the case of the wheels provided in the trailer, the large chemical liquid control device consisting of a one-point type is provided with a wheel of a non-powered structure and configured to move the trailer together with the movement of the tractor, and the small chemical liquid control device of the three-point type. In the movement, the tractor was lifted by the tractor and moved to a place where control was necessary, so that a separate wheel was not provided to control pesticides.

The technical field to which the present invention belongs among the various configurations of such a tractor-attached chemical liquid control device relates to a small chemical liquid control device that is used to attach the three-point type to the tractor.

That is, as shown in Figure 2, is coupled to the rear of the tractor is moved from the ground at a certain height when moving, and when the control work is attached to the structure of the small caster attached to the lower end of the loading box to be carried out in the state laid down on the farm In the case of a three-point chemical liquid dispenser, the trailer liquid container is lifted from the ground by a tractor in a state where the liquid container of the trailer is not filled with the liquid or water, and the liquid container is filled with water and diluted in the water supply area. It is configured to be able to control the liquid in the required farmland.

However, if water supply is difficult in the arable land, it should be moved to the arable land with the liquid container filled with water from a remote place. At this time, the pesticide control device moved to the lifted state by the tractor is heavy and the front part of the tractor is lifted. This has caused a danger to the tractor's running safety.

Therefore, it was difficult to move the tractor with the liquid container filled with water to the cultivated farm in the remote area, and in particular, the trailer of such a three-point chemical liquid controller was equipped with a small caster attached to the bottom of the loading box and a small caster to control the chemical liquid.

Hereinafter, the operation and effects of the tractor-attached chemical liquid control device according to the embodiment of the present invention made up of the above-described structure and configuration will be described in detail with reference to the conventional chemical liquid control device based on the preferred embodiment.

That is, the chemical liquid control device according to the present invention is designed to be suitable for a chemical liquid control device made of a three-point coupling structure of the conventional tractor-attached chemical liquid control device.

In the case of a chemical liquid control device having a three-point coupling structure, it is used to control small-capacity chemical liquids compared to the one-point structure, and is coupled to the rear of the tractor to control the chemical liquid by the power of the tractor, as well as the chemical liquid in the chemical container. When this unfilled tolerance is lifted by the tractor, the movement is made.

The trailer of the three-point chemical liquid control machine is a conventional small trailer attached to the bottom of the loading box in the conventional case, it is configured to be controlled on the ground after being moved to the state lifted by the tractor to the farmland that needs control In fact, the caster provided at the bottom of the loading box had a function that can be used to change the direction of the trailer and the chemical liquid conditioner while being located on the ground rather than being used to tow the trailer on an unpaved farm.

In addition, when it was necessary to move the chemical liquid control machine, the trailer filled with the chemical liquid had to be lifted and moved to the required position, and such movement was possible only at a short distance. In particular, when it is difficult to supply the water necessary for the control directly near the cultivated land where the control is made, the water is filled in the medicinal container from the remote place and used to move to the cultivated land. There are many problems in driving stability of the tractor because it occurs during operation.

However, in the case of the chemical liquid control device according to an embodiment of the present invention, the wheel 70 of the size of the trailer 10 is provided so that there is no inconvenience in carrying the trailer 10 deliberately, and therefore, the stability of the operation thereof. It is possible to increase the filling of the liquid container with water or chemical liquid to enable long-distance operation.

In addition, in the case of the conventional three-point chemical liquid control device, even if the wheel is attached, the trailer is moved together with the rotation of the tractor moving forward, so that the wheels fixed to the bottom of the trailer's loading box are not rotated to make a turn. When the wheel is dragged to the ground at a certain distance, the wheel is dragged, and the side of the wheel suddenly wears out due to the drag of the wheel, and when the wheel is punctured while concentrating the load, it often causes great obstacles in the work. .

However, in the case of the chemical liquid control device according to an embodiment of the present invention, the tractor 70 is provided with a wheel 70 and an axle 75 so as to be rotated separately from the loading box 15 on the bottom of the loading box 15 of the trailer 10. Even if the direction (T) is sharply changed, after the body of the trailer 10 is rotated in the same manner as the tractor, both wheels 70 and the axle 75 are moved according to the moving direction of the trailer, so that the wheels as before. It is not attracted to the ground, and this does not cause any puncture of the wheels, so that the work is not disturbed.

In addition, the vertical center axis of the wheels 70 on both sides of the trailer 10 of the chemical liquid control device according to an embodiment of the present invention to be bent at a predetermined angle in the opposite direction to be moved by the diffraction member 65 of the vertical rail carriage 60. Since it is refracted, the linearity of the wheels is maintained when the trailer with the heavy weight of the chemical liquid is stored to improve driving safety.

In addition, although the hose reel is configured to automatically wind the spray hose of the conventional chemical liquid control machine, the hose reel whose power transmission is blocked by the self-weight of the spray hose filled with the chemical liquid wound on the hose reel is continuously rotated by the inertia force After the rotation has been stopped or the rotation has been stopped, rewinding in the opposite direction of the initial rotation was often caused by the injection pressure and flow of the chemical liquid filled in the spray hose.

Therefore, even if the conventional chemical liquid sprayer is equipped with a spray hose automatic winding device, the alignment state of the spray hose is twisted or distracted, and there is inconvenience in that a separate effort is required for the alignment of the spray hose during or after the work. In this case, the hose reel brake 39 is provided on one side of the fixed frame 13 of the chemical liquid dispenser to stop the rotation of the hose reel 32, so that the operator loosens or winds the spray hose to the required length, and then operates the brake lever. It is configured to forcibly stop the rotation of the hose reel (32a) by operating (39a) so that the spray hose is not twisted separately during or after the operation so that unnecessary time and labor are not consumed in the spray hose alignment.

The tractor-attached chemical liquid control device according to the present invention having the above-described structure and configuration improves the safety of operation of the chemical liquid control device towed to the tractor, thereby preventing safety accidents and improving work efficiency, and when winding up or releasing the spray hose. It is equipped with a brake device of the rotating hose reel is easy to stop the hose reel to prevent twisting of the spray hose or unnecessary work volume.
