Description

An Apparutus for Distributing agricultural chemicals Using a Tilting Bar}

The present invention relates to a folding pesticide spraying device using a tilting bar for easily spraying a pesticide in a large area by using a folding member having a long length.

Pesticide application is recognized as an essential task in most of the cropland, except for the fields that grow organic crops.

This pesticide spraying work not only induces pesticide poisoning of workers but also requires strong power and stamina. In view of the aging rural environment, pesticide spraying was a very burdensome task.

Conventionally, a hose that is carried in a vehicle equipped with a power sprayer (cultivator, tractor, truck, etc.) is released to a farmland and sprayed with pesticide while moving the farmland while the sprayer connected to the end of the hose is held by the worker. Most of the time.

However, the above-mentioned operation has a problem that a strong force and a strong force are required because a heavy hydraulic hose must be pulled by a worker while a strong hydraulic pressure is applied.

In addition, there was a problem that requires a separate worker to supply and organize the hose to prevent the hose from being twisted and damage to the crop due to the hose.

Recently, since the agricultural land is well organized and large arable land is mainly used, the spraying of pesticides can be performed relatively quickly, but the above problems have been highlighted. (Agricultural arranging is usually divided into parcel units and is made up of 100m wide x 50m long (one parcel, approximately 1,500 pyeong).

In order to solve the above problems of pesticide spraying, a pesticide spraying method using an unmanned helicopter and smoke control method of spraying pesticides in the form of smoke have been devised.

However, the method using the unmanned helicopter has been used only a very small portion because of the enormous cost and high level of skill, it has not been widely used.

In addition, smoke control method was used only in part because the control effect is not meet the expectation, and there is a problem that the pesticides spread not only to the agricultural land to be sprayed pesticides, but also to unwanted surroundings.

In addition, although a pesticide spraying device in which a plurality of pesticide spraying nozzles were installed on a long truss, such as Korean Utility Model Application No. 20-1996-058676, was found, it was difficult to cover a farmland with a large length of the truss, and a considerable weight and volume. Due to the nature of the device having a significant difficulty in movement has not been practical.

And, as shown in Figure 1 has been disclosed a method for spraying pesticides using a foldable member having a long boom, in the pesticide supply device 70 to the boom bar toward the spraying destination direction through the rotating shaft (6). Then, the spraying hose (high, a plurality of folding member 10 to expand the position of the injector 800 near the destination, and to spray the pesticide in the direction to spray to the injection nozzle 83 through the injection rotating shaft 85 do.

Since the folding member 10 of such a long length forms a cantilever structure, the longer the length, the greater the vertical load. Accordingly, in the prior art, a leg 40 is installed at one end of each folding member to support the load so as to support the load.

However, when the leg 40 is actually installed on the rice fields or fields, since the land falls to the ground where the crops are located, the utilization thereof becomes extremely low in reality. In addition, even when actually working, since the floor where the leg is located when moving to another position is a paddy field, the wheels located on the leg cannot be utilized at all, and thus, the leg needs to be folded up and rotated or moved.

The present invention is to solve the above problems, and more particularly to support the vertical load while forming a long length folding pesticide injector in the form of a cantilever beam in order to easily spray pesticide on large arable land And, according to the purpose to provide a pesticide spraying device that can obtain a good pesticide spraying effect by enabling a free length change and rotational movement accordingly.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment for a folding pesticide spraying device using a tilting bar according to the present invention will be described in detail.

Prior to this, terms and words used in the present specification and claims should not be construed as being limited to ordinary or dictionary terms, and the inventor should appropriately define the concept of the term to describe its invention in the best way The present invention should be construed in accordance with the meaning and concept consistent with the technical idea of the present invention.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

Hereinafter, the configuration and the preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 7.

Hereinafter, the technical idea of the present invention will be described more specifically with reference to the accompanying drawings.

The present invention relates to a pesticide spraying apparatus using a tilting bar for spraying pesticides on large arable land, and in particular, to support the vertical load according to the cantilever structure in a long folding folding structure with a tilting bar and a wire.

Therefore, the pesticide spraying apparatus of the present invention also has a sprayer 80 which is provided with a spraying nozzle 83 for spraying pesticides as shown in Figs.

In addition, it has a pesticide supply hose 81 for supplying the pesticide stored in the pesticide storage tank to the sprayer 80, compression means for compressing the supplied pesticide so that the supplied pesticide is strongly sprayed through the sprayer 83 It has a pesticide feeder 70 having.

Then, the injection nozzle 83 is adjusted to the spraying destination direction through the injection rotation shaft 85 to be able to spray the pesticide.

In addition, the pesticide supply device 70 is provided with a rotating shaft 60 to rotate in accordance with the direction of the area where the entire folding member is sprayed, so that the vehicle equipped with the present invention is stopped and fixed large Make it possible to rotate along the radius of rotation, depending on the destination of the application.

The general form of the sprayer 80 or the pesticide feeder 70 using the rotary folding member by mounting the pesticide spraying device in such a vehicle is shown in Figs. 1 and 2, and the present invention is naturally related to the configuration and operation relationship. It is employ | adopted and since it is already well-known, a detailed description is abbreviate | omitted.

Hereinafter, the configuration of the present invention will be described in more detail with reference to FIGS. 3 to 7.

Accordingly, the present invention has an object of making it easy to spray pesticides on large arable land, excellent spraying effect, and quick spraying. Pesticide spraying method excellent in the spraying effect is a method of spraying the liquid containing the pesticide ingredient directly to the crops of the farmland through the spray nozzle for spraying pesticides (83).

Invention included in the present application is a method of spraying pesticides using a telescopic type folding member 100, which is adjustable in length, so that it can be used in a large arable land while using the spraying method as described above.

That is, provided with a sprayer 80 is provided with a spray nozzle for spraying pesticides 81, the sprayer 80 is sprayed with pesticides while moving together when the length adjustment is made by the folding member 100, or folded folding member ( It is implemented to spray pesticides while moving along 100).

The sprayer 80 moves along the folding members 100 and sprays pesticides such that the sprayer 80 moves along the folding member 100, such as a trailer or a vehicle running on a rail, to spray pesticides. Although, such a configuration and technical method is applicable by using a known technology, a detailed description thereof will be omitted.

By the way, if the length adjustable folding member 100 is made to adjust the length toward the upper, such as a boom provided in the conventional crane, not only does not reach the pesticide spraying effect expected, it is difficult to quickly spray the pesticide on a large farmland.

In other words, in order to spray pesticides on large cultivated lands quickly and to have excellent pesticide spraying effect, the pesticides should be sprayed low at the upper part of the crops but should be horizontally sprayed. Stretches while rubbing the ends)

This is because the long folding member forms a cantilever structure, causing sagging and failing to support the overall load, thereby causing the folding member to break.

In order to prevent the deflection and the damage caused by the load of the cantilever structure, the leg is further provided so that a portion which is not fixed to the folding member is seated on the ground and is supported by the folding member in a state in which the plurality of folding members are unfolded to a set length.

When applying the conventional pesticide spraying device according to the long length folding member, if the legs must support the load should be supported on the arable land, such as paddy fields below. However, in reality, when the leg is mounted down on the farmland, damage to the crops, or when the position is moved, management problems such as difficulty of work such as folding and unfolding the legs again and extending the legs, and the breakage of the legs occur.

To this end, the present invention eliminates the leg and allows the cantilever beam load to form a long length cantilever structure according to the truss structure with a tilting bar, a wire and a support member thereon.

Looking at the folding pesticide spraying device using the tilting bar of the present invention in detail with reference to Figures 3 and 4, the present invention is made in the folding pesticide spraying apparatus to be sprayed at a distance separated from, the pesticide is stored in the tank A pesticide supply device for supplying pesticides; The telescopic type is formed to be adjustable in length, and when unfolded, a plurality of folding member 100 is to be expanded from a point close to the fixed reference point; A hydraulic jack to allow the plurality of folding members to be folded or unfolded; A support member 200 to receive an axial force in the truss structure when the folding member protrudes upward from the end portion; A tilting bar 300 which hinges at the upper end of the support member and increases an angle between the support member as the folding member is unfolded; A wire 400 fixed to both ends of the folding member and connected to the end of the tilting bar to receive a tensile force in the truss structure when the folding member is unfolded; A rotating shaft for rotating the plurality of folding members to set a pesticide spraying point in a desired direction; An injection hose which is extended to the spraying target while adjusting the length of the folding member together; And a spray nozzle for spraying pesticides to a target of pesticide spraying at the end of the folding member; and using a cantilever structure to spray pesticides to remotely spaced pesticide spraying destinations located at various radii and distances.

Accordingly, the pesticide supplying device, the hydraulic jack, the rotating shaft, the injection hose and the injection nozzle are present in the conventional folding pesticide supplying device, and the present invention can employ the above configuration, and the process described above with reference to FIGS. Since it has been described, the description thereof will be omitted below.

And, although the hydraulic jack is not shown in Figures 1 and 2, the folding member 100 of the present invention may be implemented in a way that is unfolded or folded hydraulically by the hydraulic jack, a rope such as a rope for expanding and folding rope You can also implement it the way you use it.

Such a configuration is generally adopted as a configuration that provides power when the folding member 100 is expanded or folded according to a folding structure such as a crane. Detailed description will be omitted.

As can be seen in Figures 3 and 4, the plurality of folding member 100 may be formed of a square tube or a circular tube having a different diameter, but preferably may be formed of a square tube. In addition, since it must be able to withstand the vertical load of the long length cantilever structure it will be formed of high strength steel.

Accordingly, the folding members are formed in a tubular member having a smaller diameter toward the end, and are generally formed in the same length, and are formed to sequentially decrease in diameter toward the folding members 100 at the ends.

By forming in this way, each of the folding member 100 is combined in the form of being inserted into the longitudinal direction of the folding member 100 in the previous step to fold and operate, and when the oppositely unfolded each folding member 100 in the longitudinal direction According to the withdrawal process, a long cantilever structure is formed.

As shown in FIGS. 1 and 2, the fixed support points of the folding members 100 are the rotating shafts 60 included in the nongya-ya supply device 70, and the rotating shafts 60 are fixed when the folding members 100 are unfolded. It is desirable to unfold from a point close to.

Wire 400 is fixed to the outer end and the inner end 150 side of the folding member 100. The wire 400 is preferably formed so as not to come in contact with the peripheral materials under the tensile force in the operating relationship of the present invention. Thus, as shown in Figures 3 and 4, the inner end 150 may be formed of a circular fixing portion to which the wire 400 is caught, thereby preventing the folding member 100 from contacting in the spaced apart space. have.

Looking at the case in which the wire 400 is fixed to the outer end, as shown in Figure 3, since the support member 200 is not formed at the last end of the folding member 100 may be a fixed portion for a separate wire.

In addition, when the circular fixing portion is formed, the length of the wire 400 is fixed while the fixed portion is contacted, and thus the tension force applied to the wire 400 is not concentrated in only one fixed portion, but is dispersed in the contacting portion. Plan the effect of making it possible. That is, by adding a contact portion of a longer length in this way it is possible to support the wire under a large tensile force through the stable fixing of the wire.

The support member 200 is a length member of a steel frame or a square tube that protrudes upward from the end of the folding member 100, and is formed to receive axial force in the truss structure when the folding member is unfolded.

Since the support member 200 is a member receiving vertical axial force, it is preferable that the support member 200 is formed at a right angle with the folding member 100 and is formed in a fixed structure. Use as a strong member. Accordingly, the support member 200 is a member receiving the axial force in the truss structure in which the tilting bar 300 and the wire 400 are formed in a straight line to receive a tensile force, thereby supporting the load of the cantilever structure.

The upper end of the support member 200 is formed with the upper hinge portion 310 hinged to the tilting bar 300, the lower end is formed with a lower fixing portion 230 is fixed to the folding member 100 wire 400 Can be.

Since the lower fixing part 230 is a structure in which the wire 400 is typically fixed as shown in FIGS. 3 and 4, the lower fixing part 230 may be formed as a circular fixing part like the inner end 150 of the folding member 100. have. As described above, the configuration of the circular fixing part allows the wire 400 to have a longer contact length so that the tensile force applied to the wire 400 can be dispersed in the contacting area, thereby providing a large tensile force through stable fixing of the wire. Make sure to support the receiving wire.

3 to 5, the support member 200 may include a pulley 233 at the bottom. The pulley 233 forms a truss structure naturally as shown in FIG. 4 while the tilting bar 300 caught on the wire 400 rotates counterclockwise as the folding member 100 is unfolded. In this operation, the wire 400 This is to eliminate friction force for smooth sliding of). The operation of the wire 400 and the tilting bar 300 according to the unfolding of the folding member 100 will be described in more detail below.

The tilting bar 300 is hinged at the upper end of the supporting member 200, and the angle between the supporting member 200 is increased while rotating in the counterclockwise direction as the folding member 100 is unfolded. 3 to 5, the tilting bar 300 is a member supporting the tensile force when forming the truss structure with the wire 400 is preferably formed of a member that is stronger in tensile force than in axial force.

The tilting bar 300 includes an upper hinge portion 310 hinged to the upper hinge portion 210 of the support member and a lower tilting portion 330 on which the wire 400 is suspended.

The upper hinge portion 310 is hinged to allow the hinge movement by the weight without the friction force at the upper end 210 of the support member 200, accordingly, the tilting bar 300 is tilted around the hinge point (axis) Can be tilted).

The lower tilting part 330 of the tilting bar is provided with a pulley 333 to which the wire 400 is caught to move without friction, and as the wire 400 is caught, the folding member 100 is unfolded. (300) and the wire 400 to make a straight line in a tense state.

The wire 400 is fixed to both ends of the folding member 100 and connected to be caught by the tilting bar end 230 to receive a tensile force in the truss structure when the folding member 100 is unfolded. The wire 400 is to be formed to be longer than the length of the folding member 100, which is the tilting bar 300 by the folding of the folding member 100 as shown in the operating relationship of Figure 3 and 4 This is because it is necessary to keep the tension constantly due to the tilting rotation of the.

Since the wire 400 is subjected to a continuous tensile force, a wire of a metal material that is generally strong in tension may be used, and one end of the wire 400 is fixed to the lower fixing part 330 of the support member 200 by an outer fixing part 410. The other end is fixed to the inner end 150 of the folding member 100 by the inner fixing portion 430. The portion where the wire 400 is fixed may be formed as a circular fixing portion formed on the lower fixing portion 330 and the inner end 150 as described above.

In addition, the wire 400 forms a structure that can be slid without friction force across the pulley 233 of the support member and the pulley 333 of the tilting bar as shown in FIGS. 3 and 4.

According to another embodiment of the present invention, as shown in FIG. 5, the member length of the tilting bar 300 may be variously adjusted. By employing the various tilting bar 300 as described above, the rotating radius of the tilting is different. In this case, the straight tilting bar-the wire can be formed to correspond to the length of the folding member 100. That is, since the folding member 100 in the present invention to form a cantilever structure having a variety of spans can be formed in a length of a variety of units, the length of the tilting bar 300 is also formed as a member of an appropriate length in accordance with this.

According to another embodiment of the present invention, as shown in Figure 6, the outer upper surface of the folding member 100 may include a wire receiving portion 130 formed of a depression in the longitudinal direction.

Although as shown in FIG. 7, when the folding members 100 are formed such that the plurality of folding members 100 have a large difference in diameter, the wires are sufficiently folded in the wire accommodation portion 130 formed as a spaced upper space. It can be intrusive together without difficulty. However, as can be seen in Figures 3 and 4 when the plurality of folding member 100 is to be inserted into the sliding in the smaller by the difference in the diameter of the wire 400 there is no space to pull together together due to the contact Malfunctions or breakage may occur.

Therefore, a separate recessed space is provided on the outer upper surface of the folding member 100 as the wire receiving unit 130 to prevent the contact by allowing the wire to be accommodated so as to enable smooth folding.

According to another embodiment of the present invention, as shown in Figure 6 and 7, the outer lower portion of the folding member 100 may include a protrusion 133 to facilitate the folding and unfolding function according to the sliding. . That is, the overlapped penetration folding member 100 is a heavy steel member, so when pulled out after penetration, a large force is required when unfolding by contact friction force. Accordingly, since more power should be provided to the hydraulic jack for drawing, it becomes uneconomical, and if the power is weak, it may be inoperable.

Accordingly, by reducing the contact area between the inner bottom face of the inner side of the folding member and the inner bottom face of the outer side of the folding member, frictional force is reduced to form a protrusion 133 which may have less power during folding and drawing. In addition, instead of the protrusion 133, it is also possible to provide a friction removing member such as a bearing to smoothly fold and draw out.

According to another embodiment of the present invention, each of the folding member 100 is to be formed of the same length. As such, when a plurality of folding members 100 of the same length are formed, when folded, they are formed as one uniform integral large member. The folding member 100 is typically formed of a unit having a length of 6 meters capable of supporting the load.

Hereinafter, with reference to Figures 3 to 5 will be described in detail the operating relationship of the folding pesticide spraying apparatus using a tilting bar of the present invention.

When folded first, as shown in FIG. 3, a plurality of folding members 100 are overlapped and the supporting members 100 are also overlapped to form a “┛” shape having a short length as a whole.

And, as shown in Figure 4, when the folded folding member 100 is slid out, the inner end 150 of the folding member 100 and the lower end fixing portion 230 of the support member 200 or the outer height of the wire The wire 400 having a predetermined length fixed to the government 410 is caught by the lower side of the pulley 233 of the support member, and is caught by the upper side of the pulley 333 of the tilting bar to be opened in the form of "ㅅ".

Here, as the wire 400 is opened, the tilting bar 300 is rotated counterclockwise from the upper hinge part 310, and the tilting bar and the wire are outside the upper end 210 and the folding member 200 of the support member 200. It consists of a straight line connecting the ends.

In this unfolded state, the tilting bar and the wire are subjected to the tensile force, and the support member is subjected to the compressive force, thereby forming the truss structure as a whole.

At this time, the lower end of the support member 200 (where the folding member is unfolded and then connected to one unit and the other unit) has a very large bending moment because the load is concentrated. Therefore, in order to support the concentrated load at the lower end of the supporting member, it is not preferable to allow the folding member 100 to be completely drawn out.

Therefore, when the folding member 100 of the present invention is fully unfolded, the overlapping portion of the folding member outer end of the previous stage and the folding member inner end 150 of the next stage maintains an appropriate length to some extent as shown in FIG. 4. By doing so, it is possible to sufficiently support the bending moment of the lower end of the supporting member subjected to the concentrated load.

Of course, when the overlapping portion (the overlapping portion of the previous folding member and the next folding member) is reduced after the folding member 100 is drawn out, a cantilever structure of a sufficiently long length can be achieved, so that the load of the overlapping part is increased. A strong moment reinforcement that can support it will be able to withdraw long enough.

The present invention relates to a technique related to the spraying device of the pesticide, so that in implementing the sprayer 80 as a component thereof, the distance from the spraying nozzle for spraying pesticides 81 to the part fixed to the folding member of the end is adjusted form You can also implement In addition, the length adjustment method may be implemented as a conventional folding type adjustment method of the folding member, and because it can be implemented by applying other well-known techniques, detailed description of this part is omitted.

The above-described embodiment is just a preferred embodiment to enable a person having ordinary knowledge in the art to which the present invention pertains (hereinafter referred to as a person skilled in the art) to easily implement a folding pesticide spraying device using a tilting bar according to the present invention. However, the scope of the present invention is not limited to the above-described embodiments and the accompanying drawings. It will be apparent to those skilled in the art that various changes, substitutions, and alterations can be made hereto without departing from the spirit of the present invention, and it is obvious that those parts easily changeable by those skilled in the art are also included in the scope of the present invention.
