Description

HERBICIDE SPRAYER FOR ATTACHED TO THE AGRICULTURAL TRACTOR [0002]

The present invention relates to a herbicide spreader mounted on a tractor and capable of removing weeds.

Generally, we use herbicide, a toxic chemical, as a method to control weeds that grow in fields.

These herbicides are sprayed by an ineffective method in which a person manually sprayes a herbicide tank while walking on the back, using a manual passive sprayer, or hung on a tractor of a beverage bottle, and then flows to the running side.

However, since the herbicide is highly toxic, it is very dangerous to be inhaled or contacted with the body. Therefore, it is necessary to pay attention to the use of the herbicide. However, since the spraying operation must be performed within a limited range, the method of mass spraying by mechanical method is not suitable.

As is well known, among the conventional herbicide spraying methods, the method using the manual sprayer is not only slowed down because it travels on a wide area, but also has a great risk of poisoning.

In addition, the method of hanging a beverage PET bottle on a tractor is problematic in that it is difficult to evenly distribute a certain amount of the solution, which causes the use of many herbicides and weakness.

It is an object of the present invention to provide a tractor-attached herbicide applicator capable of enhancing work efficiency and eliminating the danger of poisoning.

Further, it is an object of the present invention to provide a tractor-attached herbicide sprayer capable of spraying a predetermined amount in a proper place.

The problems to be solved by the present invention are not limited to the above-mentioned problems, and another problem that is not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a tractor-attached herbicide sprayer comprising:

A first support bracket attached to one side of the tractor;

A second support bracket attached to the other side of the tractor;

A tank supported on one side of the first support bracket to allow the herbicide to be filled therein;

A spraying unit mounted on one side of the tank for pumping the herbicide, a spraying unit having one end connected to the pump, and a spraying nozzle installed at the other end of the spraying pipe;

A piston rotatably hinged to one side of the second support bracket; a piston inserted into the cylinder and horizontally reciprocable; one end hinged to the other side of the second support bracket so as to be rotatable; An injection height adjusting unit which is fixedly installed and has a rotation bar in which a tip of the piston is fixedly installed in the middle;

.

The first support bracket

And an extension portion extending from the seating portion is provided on the other side.

In the pump,

And a lever switch for turning on and off the pumping operation is connected.

The intermediate portion of the injection pipe,

And an extension portion of the first support bracket is supported via a flow path opening / closing valve.

In the cylinder,

And a rotary switch for controlling the supply of pressure to one side or the other side is connected.

As described above, according to the tractor-attached herbicide sprayer of the present invention, since the herbicide can be sprayed while traveling on the inside of the tractor, the work efficiency can be increased and the risk of poisoning can be basically eliminated.

In addition, since spraying can be performed by adjusting the height of the nozzle spraying according to the height of the bottom surface, the use of herbicide can be reduced, and the damage can be prevented.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and not all of the technical ideas of the present invention are described. Therefore, It should be understood that various equivalents and modifications may be present.

1 to 3, a tractor-attached herbicide sprayer according to an embodiment of the present invention includes a first support bracket 10 attached to one side of a tractor T; A second support bracket 20 attached to the other side of the tractor T; A tank 30; An injection unit (40); And an injection height adjusting unit 50.

Here, the tractor T is provided with a vehicle body on an upper portion of a chassis provided with a power system, and the vehicle body includes a cockpit 5 and an engine room (not shown). At this time, the cockpit 5 can be made obscured and isolated from the outside.

The first support bracket 10 is fixed to a side of the engine room of the tractor T by bolts and has a seat portion 11 to which the tank 30 can be seated on one side, And an extension 12 extending from the seating part 11 to the other side.

The second support bracket 20 may be bolted to a footrest P provided on the entrance side of the cockpit 5 of the tractor T. [

The tank 30 is seated in a seating part 11 formed at one side of the first support bracket 10, and the herbicide can be filled in the tank 30 through the upper side thereof. A water level identification pipe 31 can be further provided on the side surface of the tank 30 to identify the level of the charged herbicide from the outside.

The spray unit 40 includes a pump 41 for pumping herbicide attached to a lower portion of the tank 30 and a plurality of spray tubes 42 having one end connected to the pump 41, And an injection nozzle 43 installed at the other end of each of the injection pipes 42.

At this time, a lever switch (not shown) for turning the pumping operation on and off may be connected to the pump 41. At this time, the lever switch is provided in the cockpit 5.

The intermediate portion of the injection pipe 42 may be installed to be supported by an extension portion 12 formed on the other side of the first support bracket 10 via a flow path opening and closing valve V (see FIG. 3). A lever may be mounted on the passage opening / closing valve (V) so that the spray pipe (42) can be opened and closed manually.

The injection nozzle 43 may be installed in a one-way or two-way manner as required, as shown in FIG.

The injection height adjusting unit 50 includes a cylinder 51 rotatably hinged to one side of the second support bracket 20 and a piston 52 inserted into the cylinder 51 to be reciprocated horizontally A rotary bar (one end of which is rotatably hinged to the other side of the second supporting bracket 20 and the other end of which is fixed to the injection nozzle 43 and the tip of the piston 52 is fixed to the middle) 53).

A rotary switch for controlling the supply of hydraulic pressure or air pressure to one side or the other side may be connected to the cylinder 51. At this time, the rotary switch is provided in the cockpit 5.

An auxiliary rotation bar 53-1 (see FIG. 2) is further provided between the hinge-engaging portion of the rotary bar 53 and the front end of the piston 52 so as to more securely support the piston 52 .

Hereinafter, the operation of the above tractor-attached herbicide sprayer of the present invention will be described.

According to the present invention, it is possible for a driver to safely control the weed that is naturally growing in a field of rice while traveling in a cockpit (5) of a tractor.

That is, when the driver actuates the lever switch in the cockpit 5 provided in a state isolated from the outside, the herbicide in the tank 30 is pumped by the pump 41.

At this time, the herbicide flows to each spraying pipe 42 connected to the pump 41, and the herbicide is sprayed through the spraying nozzle 43.

In some cases, there is a difference in the height of the fields and the height of the slats bounding the edges of rice fields and fields is high. In this case, the spray height adjustment unit 50 is adjusted to adjust the spray height.

That is, when hydraulic pressure or air pressure is supplied to one side or the other side of the cylinder 51, the piston is horizontally moved in one direction so that the rotation bar 53 is rotated, so that the jetting height of the jetting nozzle 43 can be adjusted will be.

According to the tractor-attached herbicide sprayer of the present invention as described above, since the herbicide can be sprayed while traveling on the inside of the tractor, the work efficiency can be enhanced and the risk of poisoning can be fundamentally excluded.

In addition, since spraying can be performed by adjusting the height of the nozzle spraying according to the height of the bottom surface, the use of herbicide can be reduced, and the damage can be prevented.
