Description

[Detailed description of the invention] The present invention relates to a chemical spraying device, and in particular, it is an improved support device for a chemical sprayer for exterminating agricultural pests, which greatly reduces the physical burden on the sprayer, and This can greatly improve the efficiency of spraying work.

Horticultural agriculture, represented by eggplants, green peppers, cucumbers, etc., is one of the leading agricultural industries in Japan. Various improvements and innovations have been made to cultivate such horticultural crops in open fields, greenhouses, etc. in order to increase profits. However, one of the concerns faced by gardening farmers is the problem of pest control. Nowadays, it is not possible to maintain high prices unless the appearance and appearance of the product is good as well as the taste, and if pest control is not done, the taste and appearance will deteriorate. Moreover, recent pests have become immune due to the extensive use of pesticides, and conventional disinfection methods cannot eliminate them. Due to the invasion of foreign pests and restrictions on the use of pesticides, etc., the disinfection work is several times more expensive than before. The current situation is that disinfection work has to be carried out more and more frequently, and during certain seasons, disinfection work has to be carried out several times a day.

This pest extermination work usually involves spraying liquid agricultural chemicals in the form of a mist, and a chemical sprayer is used for this purpose.

Conventionally, pest control work using a chemical sprayer involves transporting a tank containing a chemical solution to an open field by car, extending a hose from the tank, applying pressure with a compressor, and spraying the chemical solution onto the crops. was scattered. In this spraying work, the worker holds the chemical sprayer in one hand and drags the hose with the other hand while walking in a zigzag pattern following the planting rows of crops in the open field. Do it by moving it. Since the chemical spray must be applied to the front and back of the leaves and stems of the crop, as well as hidden areas, the chemical sprayer must be rotated, pulled, and returned with one hand to evenly spray the crop, its surroundings, leaves, and other areas. The operation must be done in such a way that the chemical solution can be applied to both the front and back of the stem. For this reason, chemical spraying work is grueling labor for both small-scale and large-scale horticultural farms, and workers often complain of physical pain such as stiffness in their shoulders, necks, elbows, and lower backs. In addition,
Spraying must be carried out in accordance with the standards for the pesticide being used, under certain climatic conditions near sunset and sunrise, and during short periods when the medicinal effects can be expected.
Therefore, conventional methods consume a lot of time and labor, cause physical fatigue to workers, and cannot be said to be efficient spraying with medicinal effects. It was becoming a harsh burden. In this way, gardeners are said to be trading their lives to produce agricultural products.

In view of these circumstances, this invention greatly reduces the physical burden on sprayers when spraying chemical solutions on crops in horticultural agriculture, greatly improves spraying efficiency, and sprays chemicals within a certain period of time for effective medicinal purposes. The purpose of the present invention is to provide a chemical liquid spraying device that can spray chemical liquids.

With the above purpose in mind, the present invention has a pair of chemical sprayers connected by hoses, connected to a single hose via a three-pronged branch pipe, and carried around the worker's waist. In addition, the chemical sprayer can be hung from a shoulder band supported around the body, allowing the worker to hold the chemical sprayer lightly in his hand and rotate it simply by operating his wrist without using his elbow. The hose can be moved and pulled back, and the hose can be easily dragged along the entire body without having to pull it by hand.

The configuration of the present invention will be described below based on an embodiment shown in the drawings. FIG. 1 is an external view of the device, FIG. 2 is an expanded view of the device, and FIG. 3 is an explanatory view showing how it is used.

In the figure, 1 is a belt that is worn around the worker's torso, and 2 is a hanging band that is attached perpendicularly to the center of the belt, and connects a pair of shoulder bands 3 and 3 made of elastic material. . The shoulder bands 3,3 have hooks 4,4 at their ends. The lower end of the hanging band 2 is slightly elongated, and a guide ring 5 is fixed to the end. A three-pronged branch pipe 6 is fixed at the intersection of the belt 1 and the suspension band 2, and hoses 7, 7 connected to the three-pronged branch pipe 6 extend forward along the outer circumference of the belt 1, and sit on the belt. It passes through guide rings 9, 9 which are rotatably fixed via 8, 8. At the ends of the hoses 7, 7, there are pipe fittings 10, 1 with fittings.
0 is installed. Pipe fitting 10,
One end of chemical solution sprayers 11, 11 is connected to 10. The chemical sprayer 11 holds the hanging ring 12 with the grip part 13.
It is fixedly attached near the
It has a sprayer 15 equipped with nozzles 14. The hook 4 can be hooked onto or removed from the hanging ring 12.

On the other hand, a hose 16 extending downward along the suspension band 2 is connected to the three-pronged branch pipe 6, the hose 16 loosely fits through the guide ring 5, and a pipe joint 17 with a socket is connected to the lower end of the hose 16. It has been done. A long hose 18 is connected to this pipe joint 17, and the hose 18 is led to a tank (not shown) storing a chemical solution.

Next, to explain how to use the present invention, the third
As shown in the figure, the belt 1 is worn around the torso of the worker 19, the suspension band 2 is extended upward along the center of the back, and the shoulder bands 3 are hung down to the torso by sandwiching the neck of the worker 19. 4, 4 as chemical sprayer 11, 11
are hung on the hanging rings 12, 12, respectively. Then, a hose 18 is connected to the pipe joint 17, and the hose 18 is connected to the tank. Therefore, the operator 19 grasps each chemical sprayer 11 with both hands using the grip portions 13, 13, opens the handle, and sprays the chemical solution from the nozzles 14, 14 to the crops. In this case, the operator 19 only needs to lightly hold the chemical sprayer 11, and the load is reduced by the shoulder bands 3, 3.
In addition to being supported by the user, the chemical sprayer 11 can be rotated up and down and left and right using the wrist, without using the elbow as a fulcrum. Furthermore, when one of the chemical liquid sprayers 11 is greatly swung downward or sideways, the other chemical liquid sprayer 11 can also be pulled by the shoulder bands 3, 3 and move. Accompanied by the effect of pine surgery on the neck and shoulders of the person 19. Generally, chemical spraying work is
Since it is applied simultaneously to crops on both sides in an open field, etc., the chemical solution sprayer 11 moves symmetrically, and the shoulders are always rubbed by the shoulder bands 3, which is extremely effective. Then, the hose 18 is attached to the hanging band 2 as the worker 19 walks.
It can be moved by being dragged by the handle, and can be transported without having to be pulled by hand.

Since the chemical sprayer 11 is supported by the waist and shoulder bands 3, 3 of the worker 19, there is no need to support the entire load of the chemical sprayer 11 with both hands. It is sufficient to guide the movement such as left and right movements. Furthermore, since the shoulder bands 3, 3 are made of an elastic material, the operation of the chemical sprayer 11 is extremely easy, and no particular burden is imposed on the operator.

According to the present invention described above, a suspension band is provided on the belt worn around the worker's torso and is worn around both shoulders, and a chemical sprayer is removably suspended from the lower end of the suspension band. The hose that connects to the chemical sprayer is supported along the belt via a pipe joint with a hook, and is configured so that it can be connected to a long hose via a three-pronged branch pipe on the back of the belt, allowing two chemical sprayers to be connected to each other. Since the worker can lightly grasp the product with both hands and perform the spraying work, the spraying efficiency is significantly improved compared to conventional methods, and disinfection work within the same area can be done in about half the time. Disinfection work that used to be done by multiple people can now be done by one person, and the physical burden on the worker is also lightened, freeing up time and leading to greater efficiency in other agricultural tasks. be. In other words, two chemical sprayers can be easily used, and they can be placed on shelves on the left and right.
Alternatively, the disinfection work can be carried out in a minute manner and can be carried out freely in accordance with the cultivation situation of the crop, such as on a flat surface, so that the efficiency can be dramatically improved. Furthermore, since it can easily support even long chemical sprayers, which conventionally have been difficult to use at the same time, two can be used at the same time. In addition, physical fatigue can be reduced by shortening the working time, and since the chemical sprayer is suspended on the worker's shoulders, the load is not supported by the hands, and the hands are not used to hold the chemical sprayer. It only needs to be used to control the direction of spraying, and the work can be done simply, quickly, and easily using the wrist without using the arms or elbows, and the long hose can be pulled with a hanging band. Since it moves as the worker walks and can be easily moved without having to pull it by hand, the worker's physical pain can be reduced overall. When the shoulder band slides from side to side, the two chemical solution sprayers have the effect of masturbating the neck and shoulders, which not only prevents fatigue the next day, but also naturally relieves stubborn stiff shoulders and improves health. It is also useful.

Furthermore, since the time required for crops can be shortened, spraying can be carried out within a certain period of time when maximum medicinal efficacy can be expected, and the effect is great even in terms of the original purpose of exterminating pests and diseases.
