Description

[Detailed description of the invention] The present invention relates to a portable powder and granular material dispersion device, and in particular, it is a simple and practical device that can uniformly spray powder and granular pesticides, fertilizers, etc. with a controlled spray amount. The purpose is to provide equipment.

Conventionally, pesticides such as particulate herbicides, fertilizers such as granular chemical fertilizers, etc. have been widely used. Large-scale mechanized devices for dispersing these powders and granules have been developed and have achieved success, but there is no satisfaction with relatively simple, portable devices, and even among farmers there is a lack of interest in these simple and granular devices. The development of a practical device is strongly desired.

The inventor of the present invention has conducted extensive research into prototyping a powder and granular material dispersion device that satisfies such demands, and as a result has developed a practically desirable dispersion device.

That is, the present invention comprises a powder storage bag, a pipe for dispersion operation connected via a bellows tube attached to a powder and granule outlet at the bottom of the storage bag, and a pipe connected to the tip of the pipe. A portable powder and granular material dispersion nozzle member comprising a powder and granular material dispersing nozzle member, a sitting stabilizing member is attached to the outer bottom surface of the storage bag so as to be horizontally rotatable, and a flow rate regulating plate is built into the tube body. A spraying device is provided.

The powder and granular material storage bag according to the present invention is a bag-like, sturdy container that accommodates the powder and granular material, and
On its upper side, an opening for supplying the powder or granules is provided, for example by means of an easy-to-open/close means, such as a fastener, and the storage bag is preferably provided with a shoulder strap or backpack for convenient carrying. A string can be attached. Furthermore, an opening for discharging powder and granular materials is formed at the bottom of the storage bag, and the opening includes:
A flexible tube, usually a rubber bellows tube, is joined. It is important that this bellows tube has a bending flexibility suitable for spreading powder and granules by swinging the scattering operation tube from side to side. Therefore, the bellows tube of the present invention has such a function. Includes flexible tubing with. A straight pipe for spraying operation, preferably a straight pipe made of hard plastic, is connected to the opening at the other end of the bellows tube, and a powder and granular material dispersing nozzle member is attached to the tip of the pipe. Further, a flow rate adjustment mechanism is provided inside the tube, which is a combination of a substrate having one through hole and a flow rate adjustment plate having a plurality of through holes of different sizes. The hole is rotated around its central axis so that the desired hole can be selected. In such a dispersion device of the present invention, the powder and granular materials in the storage bag flow down from the removal opening at the bottom of the storage bag, pass through the bellows tube and the tube body, and in the tube body, there are The liquid flows through the selected holes of the flow control plate to reach the spraying nozzle member, and is discharged and sprayed from the nozzle onto a field or the like.

The desired scattering of the powder and granular material is achieved by lowering the storage bag over the shoulder, tilting the dispersion operation tube downward and swinging it from side to side while walking and scattering the powder and granular material. In addition, in the device of the present invention, a seat stabilizing member is attached to the outer bottom of the storage bag to make the bag sit better, so it can be used even when a large amount of powder or granular material is contained. Not only is sitting stability obtained, but the bag itself is kept off the ground and its soiling is effectively prevented.

This invention provides the following advantages and effects.

(1) A pipe body with a spray nozzle attached to the tip is connected to the storage bag (or container) via a bellows tube, so the operator can grasp this pipe body and freely move it left, right, up and down. Therefore, the desired spraying can be easily carried out.

(2) Since the pipe body has a built-in powder flow control plate, the amount of spray per fixed area can be easily adjusted and set during spraying. For example, the appropriate amount of herbicide to be sprayed on rice fields is approximately 3.5Kg/10a,
For upland fields, it is said to be about 5.0 kg/10 a, but according to the present invention, it is easy to spray according to a predetermined standard regardless of the size of the sprayed area.

(3) According to the present invention, even highly toxic pesticides can be sprayed safely and easily without the need for hand-sprinkling. In particular, the convenience of being portable and easy to use is a noteworthy advantage from a practical standpoint.

(4) Furthermore, a sitting stability member (hereinafter referred to as an attachment) is provided on the outside bottom of the storage bag so that it can rotate horizontally, so when placing the storage bag on the bottom, the attachment can be moved in the longitudinal direction of the bottom of the storage bag. By arranging the storage bag at a nearly right angle, the storage bag can be placed stably without rolling to the side.

Hereinafter, an example of the spraying device of the present invention will be described based on the accompanying drawings.

FIG. 1 shows an example of a shoulder-type bag for storing powder and granules. A tube body 3 is connected to the bag body 1 via a bellows tube 2, and 4 is a shoulder strap;
5 is an attachment attached to the bottom of the bag. This attachment is installed so that it can be rotated horizontally, so when placing the bag on the floor during work, etc., by keeping this attachment at a nearly right angle to the longitudinal direction of the bag, the bag will sit more stably. This prevents the product from being replaced laterally. Although the bag 1 is shown to be of a shoulder type, it may also be of a backpack type. The material of the bag is not limited to cloth, plastic, etc., but it is recommended that the sides and bottom be made of strong cloth, the top made of a transparent material (so that the inside can be observed), and that an opening and closing part be provided. . It is desirable that the bellows tube 2 be made of synthetic rubber and the tube body 3 be made of plastic.

FIG. 2 is a sectional view showing a state in which the dispersing nozzle member 6 is connected to the tip of the tube body 3, and the flat dispersing nozzle member 6 is shown in a top view in its flat state. 7 indicated by a dotted line is a protrusion provided inside the flat part of the nozzle, and the powder particles flowing from the tube collide with this protrusion 7 and are scattered in all directions. Reference numeral 8 denotes a flow rate adjustment plate built in near the tip of the tube, the details of which are shown in FIG.

That is, FIG. 3A shows the board, which is fixedly installed. FIG. 4B shows a flow rate control plate, which is rotatably installed parallel to the substrate. 9 indicates screw parts for installing them, 10 and 11a to 11d are holes provided in the adjustment plate, and 10 and 11 are holes in both adjustment plates.
The amount of powder and granular material flowing out becomes the maximum when the point a becomes bulky, while it becomes the minimum when the point 10 and 11d become bulky.

Fig. 4 shows the mode of the attachment, and Fig. 4A shows the case of one attachment;
B shows the case of two pieces, which are mounted so as to be horizontally rotatable around a fixed axis P.

The present invention has the above-mentioned configuration, which provides the advantages described in 1 to 4 above.
The practical value is enormous.
