Description

Golf Controls {PEST CONTROL VEHICLE FOR GOLF COURSE}

The present invention relates to a control vehicle, and more particularly, to a control system for golf courses that can more efficiently and uniformly spray drugs such as pesticides on the golf course.

The grass formed on the golf course is very thin because of its thin leaves and short growth length, while being vulnerable to pests and affected by weeds. Therefore, persistent and meticulous pest control and weed control are needed so that grass is not affected by pests and weeds. Pest control and weed control usually use the method of spraying the grass composition with the herbicide, fungicide, insecticide, etc. as a control car.

The control vehicle is capable of driving, and has an engine, a power transmission device, a steering device, etc. necessary for driving, and also a drug injection facility required for injection of drugs, for example, a drug tank, a drug pump, and a drug injection nozzle. Doing. Such a control vehicle is to slowly move along the road formed in the golf course to spray drugs such as herbicides, fungicides, insecticides on the grass composition.

On the other hand, such a control vehicle is configured to spray the drug while moving along the road, there is a disadvantage that it is disadvantageous to spray the drug on the grass composition of the far distance relatively far from the road. In addition, the conventional control vehicle has a disadvantage that it is somewhat disadvantageous to spray the drug on the grass composition of a large area formed on both sides of the road because the width of the control is small.

In view of this, in recent years, a remote control spray is possible, and a spray control vehicle capable of spreading the spray to both sides has been developed and used. As an example, in Korean Utility Model Registration No. 17246, a link bracket which can be lifted and mounted on a frame of a vehicle body is installed, and a middle boom is fixedly installed on the link bracket, and a side having a plurality of spray nozzles at both ends of the middle boom. There is proposed a boom sprayer in which the boom is foldable.

The boom sprayer is configured to elevate the link bracket to an appropriate height, then to spread both side booms and to spray the medicament through the spray nozzles of the unfolded side booms.

On the other hand, such a boom sprayer has the advantage that it can control a relatively far and large area by increasing the width of the control, it is pointed out that when the side boom is raised to spray the drug at a higher position, its height is limited have.

In other words, in order to spray the drug at a higher position, the link bracket must be raised higher, and the lift height of the link bracket is relatively short, so that the lift height is relatively limited, and thus the lift height of the side boom is also limited. It is. Of course, the height of the link bracket may be increased by lengthening the frame of the vehicle body for guiding the lifting movement of the link bracket, but in this case, the driver's view may be obscured by the link bracket having the increased height. There are disadvantages in that various factors must be taken into consideration, such as an increase in the operating stroke of the actuator for moving the link bracket in proportion to the increase in the height of the link bracket.

In addition, the conventional boom sprayer has the disadvantage that the drug is sprayed only in the side boom spread on both sides, so-called "non-sprayed area" where the drug is not sprayed in the area between the side boom, that is, the width of the vehicle body is formed. There is this. This disadvantage causes the boom spray to move directly to the grass composition and spray the medicament, which can not control the grass as much as the width of the body. On the other hand, the problem is that the boom sprayer must be reciprocated several times to spray the medicament to the non-sprayed grass, and the "double control" to control the same place several times during the reciprocating boom sprayer several times. It causes another problem that cannot be avoided. Overlapping causes many problems such as waste of drugs and increased environmental pollution.

Therefore, the present invention has been made to solve the above disadvantages, the object is to increase the spreading width of the drug to control the farther and wider grass composition while at the same time increase the spraying height of the drug to increase the control efficiency It is to provide a control system for golf courses configured to improve as much as possible.

Another object of the present invention is to provide a golf course control vehicle configured to maximize the width of the control by allowing the spraying of the drug even in the non-spreading area between the side booms.

In order to achieve the above object, the present invention provides a golf car control car for spraying the drug, the vehicle body; A pair of vertical support pillars fixed side by side at intervals on the vehicle body, and a pair of upper arms with one end rotatably supported on each of the vertical support pillars; A pair of lower arms having one end rotatably supported at each of the vertical support pillars so as to be disposed below the upper arm; A pair of connecting arms rotatably supporting the other ends of the upper arm and the lower arm disposed up and down; A cross beam connecting each other so that the pair of connecting arms can interlock with each other; A boom actuator that opens or deflates the upper and lower arms so that the upper and lower arms can pivot up and down with respect to the support arm; A pair of side arms rotatably installed at both ends of the cross beam between a folded position folded on the vehicle body and an open position on both sides of the vehicle body; A side arm actuator for rotating the side arms from the folded position to the extended position or from the unfolded position to the folded position; It is fixed to both side arms, characterized in that it comprises a pair of side nozzle assembly which can spray the drug to both sides of the vehicle body.

Here, since the engine, the power transmission device, the steering device, and the medicine tank and the medicine pump of the medicine injection facility are installed in the vehicle body 10, the detailed description thereof will be omitted.

On the other hand, the control vehicle of the present invention has a pair of linear side nozzle assembly 20 that can spray the high-pressure drugs pushed from the drug pump to both sides of the vehicle body 10, as shown in Figure 1 and 2, As shown in FIG. 1, the side nozzle assembly 20 is provided with a boom assembly 30 which supports the vehicle body 10 so as to be able to be lifted up and down while being folded at the same time.

The boom assembly 30 has a vertical support pillar 32 fixedly installed in a state perpendicular to the rear of the vehicle body 10. The vertical support pillars 32 are provided in pairs at intervals on both rear sides of the vehicle body 10 as shown in FIG. 2.

And the boom assembly 30 is a pair of upper arms 33, one end of which is rotatably supported on top of each vertical support pillar 32 on both sides, as shown in Figs. A lower portion of the support pillar 32 has a pair of lower arms 34 whose one end is rotatably supported. Here, the upper arm 33 and the lower arm 34 supported above and below each vertical support column 32 are configured to have the same length.

The boom assembly 30 rotatably supports the other ends of the upper arm 33 and the lower arm 34 disposed above and below each vertical support column 32, and the upper arm 33 and the lower arm. It has a pair of connecting arm 35 which connects each other so that 34 may maintain parallel state. In addition, the boom assembly 30 has a cross beam 36 connecting the connecting arms 35 to each other so that both connecting arms 35 can be simultaneously linked as shown in FIG.

Here, as shown in FIG. 1, the connecting arm 35 connecting the upper arm 33 and the lower arm 34 in a parallel state maintains a parallel state with the vertical support pillars 32 facing each other. In this way, the connecting arm 35 is in parallel with the vertical support pillar 32, the upper arm 33 and the lower arm 34 is in parallel, the vertical support pillar 32 and the upper arm 33 As the connecting arm 35 and the lower arm 34 are rotatably connected to each other, the vertical support column 32 and the upper arm 33 and the connecting arm 35 and the lower arm 34 are connected to each other. Parallel four-link mechanism (hereinafter referred to as a vertical support column 32, an upper arm 33, a connecting arm 35 and a lower arm 34) configured to be parallel to each other and to be rotatable relative to each other. Link mechanism 31 ". In addition, of the vertical support pillar 32, the upper arm 33, the connecting arm 35 and the lower arm 34 forming the four-link link mechanism 31, the vertical support pillar 32 is attached to the vehicle body 10. As it is fixedly supported, the remaining upper and lower arms 33 and 34 and the connecting arm 35 can pivot up and down using the vertical support column 32 as a supporting point.

On the other hand, as shown in Figure 2, as both connecting arms 35 are connected to each other by the cross beam 36, the four-section link mechanism 31 on both sides, that is, the vertical support column 32 and the upper arm on both sides Reference numeral 33 and the connecting arm 35 and the lower arm 34 interlock at the same time.

1, the central portions of the upper arm 33 and the lower arm 34 constituting the four-section link mechanism 31 are connected to each other by an auxiliary connecting arm 35a. The auxiliary connecting arm 35a can move while maintaining a high coupling force between the vertical support pillar 32 and the upper arm 33, the connecting arm 35 and the lower arm 34 constituting the four-section link mechanism 31. It helps to help

Referring back to FIG. 1, the boom assembly 30 extends or pinches the connecting arm 35 and the lower arm 34 which are rotatably connected to each other to increase or decrease the crossing angle α of the boom actuator. Equipped with 37. The boom actuators 37 are linear actuators that are electrically operated, the body 37a being rotatably coupled to the connecting arm 35 with a pin 37b, and the actuating rod 37c being the lower arm. A pin (37d) is rotatably coupled to the (34). Here, the boom actuator 37 is disposed between both four link mechanisms 31, as shown in Figure 2, the support bracket of the cross beam 36 for connecting both connecting arms (35) ( The body 37a is rotatably supported on both connecting arms 35 through 36a, and is also shown in FIG. 1 through a crossbar 34a for connecting both lower arms 34. Likewise, the actuating rod 37c is rotatably supported by both lower arms 34.

The boom actuator 37 of such a configuration expands or contracts by an applied electric force to increase or decrease the crossing angle α between the connecting arm 35 and the lower arm 34, thereby reducing both four link mechanisms ( 31), thereby allowing the entire boom assembly 30 to rotate up and down. Here, the reason why the four-section link mechanism 31 rotates as the boom actuator 37 increases or decreases the crossing angle α between the connecting arm 35 and the lower arm 34 is the boom actuator ( When 37 increases or decreases the crossing angle α between the connecting arm 35 and the lower arm 34, the force is equally equal to the vertical support column 32 and the upper arm as shown in FIGS. 3 and 4. It acts as a force to increase or decrease the cross angle of (33), wherein the vertical support column 32 is fixed to the vehicle body 10, so only the upper arm 33 is the upper side with the vertical support column 32 as the support shaft. Is to rotate to and below. As a result, as the upper arm 33 rotates to the upper and lower portions, the connecting arm 35 and the lower arm 34 connected thereto rotate at the same time, and the upper and lower portions thereof. As a result, the entire boom assembly 30 is elevated upward and downward. You can exercise.
