Description

[Detailed description of the invention] (Field of application of the invention) This invention is a simple agricultural chemical for hand-spreading solid agricultural chemicals or fertilizers in the form of powder, crystals, or granules in fields, small-scale farmland, home gardens, etc. Regarding the spreader.

(Prior Art) Despite the warnings of the late Ms. Carson in her famous book "Silent Spring," as a practical matter, the use of pesticides is essential for increasing agricultural productivity. In large-scale agriculture, pesticides are sprayed using helicopters or powered spreaders, but in small-scale agriculture, hand-cranked dusters or direct hand-spreading are used. However, since pesticides are often toxic, there is a risk that pesticide powder will be absorbed even when spread by hand or even using a duster. Particularly in the case of concentrated targets such as fields, small-scale farmland, and home gardens, it is desirable to be able to spray in a manner that poses as little danger to the sprayer as possible, and at an average concentration.

From the above point of view, in recent years, mainly in paddy rice fields, the shape of a box with a mouth, which has a shape (just like a dustpan) in which both opposing side walls of a box-shaped body are cut out diagonally symmetrically, as shown in the attached Figure 7, is being developed. A spreader 1' is used. When in use, pesticides (C; mainly granular) are placed in the box-shaped body and sprayed by tilting the mouth part 2' slightly and shaking it from side to side. However, the angle of repose of pesticides varies considerably depending on the type, and it is difficult to maintain the angle of depression of the mouth accurately, so it takes a high level of skill to maintain the flow of pesticides at a roughly constant rate. I need. Therefore, it is difficult to spread it evenly unless you are very experienced.

(Purpose of the invention) The purpose of the invention is to improve the shortcomings of the above-mentioned known simple sprayers and to provide an improved simple sprayer that allows even beginners to achieve the purpose of average spraying. .

(Means for achieving the purpose) In order to achieve the above-mentioned purpose, the simple sprayer according to the present invention has a box-like body with a protruding mouth, which has a shape in which both opposing side walls of the box-like body are cut out diagonally. It is characterized in that a narrow weir plate is erected inside the edge, and a large number of small holes are present in the bottom plate near the protruding edge.

With reference to FIG. 1 (cutaway perspective view) and FIG. 2 (cutaway plan view) showing the prototype of the article, the whole 1 is as follows:
Using any rigid material such as hard paper, plastic thin plate, plywood plate or metal thin plate, a rectangular virtual box-like body (B; virtual line It is made in a shape in which parallel both side walls 1b, 1b of (indicated by ) are cut out diagonally symmetrically along the plane abcd (indicated by a chain line). however,
Unlike the one in FIG. 7, the cut section abcd slightly intersects the front surface _Bf of the box-like body B. For this reason,
A part of the front wall of the box-like body remains as a solid body and forms a weir plate 3 that extends below the opening 2.

The through holes (small holes) 4, 4... are the bottom plate 1 of the sprayer 1.
There are two rows of holes in the front of c. The size of these pores is determined experimentally depending on the particle size of the agricultural chemical to be sprayed. In order to equalize the amount of particles passing through, it is more preferable that the holes are arranged in a staggered manner as shown in Examples below.

Metrically, scale lines 5, 5... are displayed on the inner surface of the top plate 1a of the sprayer 1, but if the top plate or side wall 1b is made of transparent plastic, It may be provided on the inner or outer surface of the bottom plate or side wall 1b.

(Operation) Now, put the drug C to be sprayed into the sprayer 1, and
If you tilt it and swing it left and right as shown in Figure 3,
The drug C is dispersed through the through holes 4. On this occasion,
Since the weir plate 3 exists at the lower edge of the mouth part 2, even if the angle of depression (θ) becomes excessive, overflow of the drug C is prevented, and an amount commensurate with the number of through holes 4 and the opening area is prevented. The drug leaks out. That is, in this sprayer, the through hole 4
Due to the presence of the weir plate 3 and the buffering effect of the weir plate 3, approximately average spraying is possible even without skill. Note that the measuring scale 5 indicates the approximate amount of the chemical content, and provides the user with a guideline for the amount to be sprayed.

(Examples) Hereinafter, two embodiments of the invention will be shown by examples, but the disclosure is of course for explanation purposes and does not limit the connotation or extension of the idea of the invention.

Embodiment 1 FIG. 4 is a developed view (back view) of a sprayer 1 as a preferred embodiment of the present invention.

The template 11 is a substantially rectangular plate made by punching out hard paper using a Thomson machine, and has fold lines (dotted lines; 16, 16...) and cut lines 17, 17...
A top plate portion 11a, a side wall portion 11b,
11b, bottom plate portion 11c, rear wall portion 11d, glue substitute flaps 18a, 18a, 18b, 18b, 18
c, 18d.

Each part of the above template 11 is bent inward at right angles along each fold line 16, and the glue substitute flaps 18a, 18a, 18b, 18b, 18
Glue the back sides of c and 18d to the corresponding parts,
A simple agricultural chemical sprayer 1 approximately similar to that shown in FIGS. 1 and 2 is completed. However, in the dispenser of this example, the small holes 4, 4, .

The sprayer of this example is constructed in an assembled manner and can be easily provided as a service product, so it can provide convenience to customers.

Embodiment 2 FIGS. 5 and 6 are perspective views of another example of the invention seen from the front side and the plane side, respectively. The sprayer of this example is characterized in that it is designed so that the agricultural chemical packaging paper carton 21 can be used as a sprayer.

Side walls 21b, 21b, front wall 21 of carton 21
A, 21a and the lid 22 are provided with linear perforation lines 29, 29, .

After taking out the medicine C in the bag inside, cut out the tear line 2.
The upper part of the carton 21 is removed diagonally using 9, 29, etc., and the remaining end of the lid 22 is bent at right angles and fixed using cellophane tape, etc., and then cut along the cutting lines 29', 29'... ... using small holes 4, 4...
By drilling ..., a simple agrochemical sprayer 1 similar to the one shown in FIGS. 1 and 2 can be obtained, and the agent can be stored inside for use.

The sprayer of this example is the most economical because the packaging carton is used as is.

(Effects of the invention) The present invention provides a simple pesticide sprayer that can evenly distribute solid pesticides or fertilizers in the form of powder, crystals, or granules by hand in fields, small-scale farmland, home gardens, etc. Through what we can provide, we can contribute to the development of agriculture and arts.
