Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of a pest control device used for disinfection, fertilization, and watering in fields, greenhouse gardening, landscaping, etc.

[Conventional technology]

Conventional pest control devices used for disinfecting and watering various vegetables and flowers grown in fields or greenhouses include hand-held pest control devices equipped with a rod-shaped pipe with a grip at one end and a number of spray nozzles; Alternatively, a mobile pest control device in which a support having a large number of spray nozzles is erected on a wheeled frame is widely known. Furthermore, chemical stationary disinfection devices are also known that are intended to disinfect the entire air inside a gardening house.

[Problem that the invention attempts to solve]

Although the above-mentioned stationary disinfection equipment is effective as a disinfectant, it is necessary to seal the entire house and perform the work at night or early in the morning when the pests are inactive and the temperature inside the house does not rise above the above level. There are problems such as unfavorable working conditions, high equipment costs, and a heavy economic burden, as well as inefficiency due to restrictions on the pesticides that can be used.

On the other hand, in conventional hand-held or wheeled mobile pest control devices, the spray nozzle that sprays the chemical solution is integrally fixed to the surface of the rod-shaped pipe or support that supplies the chemical solution, so the nozzle sprays out the spray nozzle. The spraying method mainly involves spraying the chemical solution onto the outer surface of the crops from above, which makes it impossible to accurately disinfect the underside of the leaves, which would provide the maximum disinfection effect, depending on the shape and size of the crops being disinfected. There was a problem.

[Means for solving problems]

In order to solve the problems of conventional insecticides as described above, this invention has been designed to easily and accurately disinfect the underside of leaves without damaging the crops, especially in response to the shape and size of the crops to be disinfected. The purpose of this invention is to provide a pest control device that can be used efficiently.

The present invention is a specific means for solving the conventional problems as described above, and is based on a plurality of stages of bearing stands having a pair of support shafts parallel to the pillars installed on a frame with wheels. and connecting both support shafts in the bearing stand with an elastic body,
Branch rods made of bendable soft wire rods or strips are horizontally protruded from each support shaft toward the outside of the support, and liquid supply tubes equipped with jet nozzles are attached to the tips of these branch rods. It is characterized by the fact that

[Effect]

The pest control device according to this invention moves the device by pulling it backwards along the furrows of agricultural crops.
Since the branch rod to which the spray nozzle is attached is made of a bendable material, when crops are in the early stages of growth, the branch rod attached to the lower half of the support can be extended horizontally and the liquid can be supplied. Use with a wide reach so that the injection nozzle at the tip of the tube can get as close to the crops as possible.

When crops reach the middle stage of growth, the disinfectant is sprayed onto the undersides of the leaves of the crops while adjusting the expansion and contraction by bending the branches into an appropriate shape to shorten the reach and changing the spray nozzles.

In addition, the base ends of the left and right branch rods are connected to a pair of support shafts on a bearing stand provided on the column, and the respective support shafts are connected to each other via an elastic body.
Each branch rod always maintains its balance in the left and right direction and protrudes horizontally due to the tension of the elastic body. Therefore, when a branch of a crop partially extends to a large extent and collides with a branch rod equipped with a jet nozzle, the branch rod will rotate around its spindle in the direction of contact with the branch of the crop and receive resistance. , Disinfection work is performed without shaking or banging the branches of the crops, thereby preventing damage to the crops. When the branch rod rotates and separates from the crop branch, the elastic body rotates the spindle to pull the branch rod back to its original position, so the branch rod returns to a horizontal state that maintains its original balance. Return and spray disinfectant on the branches of the next crop.

〔Example〕

Next, a preferred embodiment of the pest control device according to the present invention will be explained with reference to the drawings. As shown in FIG. It is composed of a support column 4 erected in front of a frame 1.

The frame 1 is made of a horizontal pipe, and a pair of distribution pipes 5 are integrally arranged on both the left and right sides.A wheel 2 is attached to the front end that rises upward, and a wheel 2 is attached to the rear end as well. A handle 3 whose height can be varied is attached. Also,
A pair of stands 6 extending diagonally downward are provided on both sides of the frame 1.

The handle 3 is provided with a branch pipe 7 having a bulk pot 8. A liquid supply hose 9 leading to a power source (not shown) is connected to the upper end of the branch pipe 7, and the lower end of the branch pipe 7 is connected to the front end frame 1. A tube 10 is connected between the rear ends of the respective distribution pipes 5 provided on both sides.

The distribution pipe 5 has valve sockets 11 and 12 at the rear end and middle part, respectively, and a large number of liquid supply tubes 13 are branched out from these distribution pipes 5. Pipes are arranged in a bundle and extend upward from the lower end portions of columns 4 erected in front of the frame 1 .

A plurality of bearing stands 14 are fixed to the support column 4 at predetermined intervals, and a pair of resin roller-shaped support shafts 15 parallel to the support support 4 are attached to both ends of these bearing stands 14.
is pivoted so that it can rotate. Further, on the outside of these support shafts 15, there are branch rods 1 made of soft metal that can be bent freely as appropriate, such as soft iron wire, copper wire, or strip plates made of these metals.
6 are provided in a protruding manner so that the fuselage 16a is mounted in a direction intersecting the support shaft 15, respectively.

Furthermore, an elastic body 17 such as a coil spring is interposed and connected between the pair of support shafts 15 in a state in which the left and right branch rods 16 protruding from the support shafts 15 are arranged substantially in the same line. The tension of the elastic body 17 holds the left and right branch rods 16 so that they are always aligned on the same straight line. In the embodiment shown in the drawings, the spring serving as the elastic body 17 connecting between the support shafts 15 is connected to the branch rod 16 that intersects with each support shaft 15 and protrudes inwardly of the shaft 15.
The elastic body 17 may be, for example, a rubber string or a rubber belt.

In this embodiment, as a means for connecting the base end 16a of the branch rod 16 to the support shaft 15, the support shaft 15 is formed into a roller shape with a large outer diameter, and the base end 16a of the branch rod 16 is connected from the outside of the roller-shaped support shaft 15. After loosely inserting the support shaft 15 so as to cross it, the elastic body 1 is inserted inside the support shaft 15.
7 and a bolt for fixing the base end 16a of the branch rod to the outer periphery of the roller-shaped support shaft 15 by mounting the tip of the hook 16b into the roller-shaped support shaft 15 again. The structure is such that 20 can be attached.

In this way, after the base end 16a of the branch rod is loosely inserted into the roller-shaped support shaft 15, when the tip of the hook 16b is fitted into the roller-shaped support shaft 15 again, the branch rod 16 is inserted into the roller-shaped support shaft 15 again. can be installed without rotating in the axial direction. Also, branch rod 1
6 relative to the roller support shaft 15 is fixed by a bolt 20, but the elastic body 17
When the branch rod 16 loses its elasticity, the bolt 20 can be loosened and the mounting position of the branch rod 16 relative to the roller support shaft 15 can be adjusted as appropriate along the length direction.

On the other hand, the left and right branch rods 16 have a large number of liquid supply tubes 1 extending from the direction of the frame 1 below.
3 are attached so as to be led out by each branch rod 16. In order to attach the liquid supply tube 13 to the branch rod 16, in this embodiment, a flexible jacket tube 18 such as a rubber or vinyl tube is inserted into each branch rod 16 in advance. The liquid tubes 13 are inserted into the sheathed tubes 18 and held by the branch rods 16 so that the jet nozzles 19 at the tips of the respective liquid supply tubes 13 protrude from the tips of the sheathed tubes 18.

〔effect〕

The pest control device according to this invention has four pillars as described above.
Since the branch rods 16 that branch out on both sides of the frame are made of flexible, flexible metal, the branch rods 16 with liquid supply tubes 13 attached thereto can be adjusted according to the growing conditions of agricultural crops.
The length of the protrusion and the vertical and front-back directions can be bent or extended into a desired shape and can be freely adjusted. As a result, the branch rod 16 equipped with the spouting nozzle 19 can be moved in a situation where it does not collide with the branches of agricultural crops as much as possible, and the chemical solution spouted from the spouting nozzle 19 at the tip of the branch rod is always completely removed from the outside of the crops. It can be sprayed evenly on the branches and leaves of the tree.

In addition, in the pest control device according to this invention, the base ends 16a of the left and right branch rods 16 as described above are connected to each other by an elastic body.
Since the branch rod 16 protrudes from the support 4 so as to be connected to the support shaft 15 connected by 7, as the vessel advances, the branch rod 16 can be used to prevent branches of crops that have partially extended abnormally, supports in the greenhouse, etc. When it comes into contact with a string, etc.
The branch rod 16 rotates around the support shaft 15, and the branch rod 1
6 can be released as is in the direction of resistance by contact. As a result, the branch rods 16 themselves do not have a large bending resistance, and the branch rods 16 do not hit the branches of the crops or cause them to move unreasonably, so damage to the crops can be prevented. The underside of the leaves can be disinfected accurately.

Furthermore, as the vessel moves, the branch rod 16 is removed from the crop 1.
When the branch rod 16 passes through a branch of a crop, a support in the greenhouse, a string, etc. and separates, the elastic body 17 between the support shafts 15 pulls the branch rod 16 back to its original position, and the branch rod 1
6 swings to automatically return to its original correct protruding position by rotation of the spindle 15, so that the disinfectant can be sprayed correctly on the branches of the next crop without any hindrance.

In addition, when moving in the air without performing disinfection work, by lifting the handle 3 upward and tilting the column 4 forward, each branch rod can hold the liquid supply tube, jet nozzle, etc. It rotates downward due to its own weight and becomes slightly narrower than the set width when expanded, allowing it to avoid obstacles and pass through, making it easier to transport.
