Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a simple manual fertilizer application and dispensing machine.

[0002]

2. Description of the Related Art Fertilizers and pesticides (hereinafter referred to as fertilizers) are stored in a hopper provided with wheels and handles, and a plurality of spraying ports opened on a bottom wall thereof are opened and closed. A man-powered fertilizer and a dispenser for spraying fertilizers and pesticides that have passed through the spray opening and the adjusting opening to the ground while operating in the field by operating a shutter having a spray adjusting opening for adjustment are known. I have. In the case of this type of fertilizer application and dispensing machine, the application amount of fertilizer etc. is adjusted by shifting the position of the application port on the bottom wall of the hopper and the application port of the shutter. If closed, the fertilizer may clog and may not fall uniformly.
In addition, since the position of the spraying port on the bottom wall is not changed, it has to be sprayed to an unnecessary part. As described above, in the conventional fertilizer and dispenser, there is a case where the amount of the fertilizer and the like and the position of the fertilizer are not adjusted freely, and the fertilizer and the like may be wasted. Further, in this type of fertilizer and dispenser, usually, a fertilizer or an agricultural chemical is rotated by a helical shaft provided at the bottom of the hopper and sequentially moved by a blade member on a peripheral wall thereof. In some cases, the application could not be evenly distributed.

[0003] The present invention provides a human-powered fertilizer and a fertilizer which can adjust the amount and position of fertilizer / medicine according to the situation, and can always apply the fertilizer and the like uniformly regardless of the shape and remaining amount of fertilizer. The task is to provide a dispensing machine.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a plurality of spraying ports are provided on a bottom wall of a hopper,
In a fertilizer and dispenser in which a shutter provided with a spray control port is provided movably below the hopper at the same interval as the spray port, a shielding plate having at least one opening is detachably mounted below the hopper. It is intended to provide a fertilizer and a chemical dispenser characterized by being provided. According to the fertilizer and dispenser of the present invention configured as described above, the relative position of the spray control port with respect to the spray port is changed by moving the shutter below the hopper, and the open / close state of the spray port is switched. The number of spray ports in an open state can be adjusted by using a size and a shielding plate having a number of openings in combination.

[0005] In one embodiment of the present invention, a pair of helical shafts that rotate in opposite directions are disposed on the bottom wall of the hopper of the fertilizer and the chemical dispenser. Further, in another embodiment, the shielding plate of the fertilizer and pharmacy is made of a thin plate made of plastic, and is configured so that an opening can be provided when used.

The "shielding plate" in the fertilizer and dispenser of the present invention is a thin plate having a desired size and number of openings or being openable. Below the hopper of the fertilizer and medicine applying machine of the present invention, there is provided an insertion portion into which this shielding plate can be removably inserted, and is provided on the hopper bottom wall at a position corresponding to the opening by inserting into the insertion portion. The spray port is opened in response to the movement of the shutter. The location of the insert may be under the shutter or between the bottom of the hopper and the shutter.

[0007] The material of the shielding plate is not particularly limited as long as it does not violate the object of the present invention.
Examples of the material include metal and glass, and plastics that have flexibility and elasticity and are easy to handle are preferable. An acrylic resin is preferred as an example.

The size, number, position, etc. of the openings of the shielding plate can be set variously according to the purpose. For the purpose of the present invention, it is convenient to prepare a plurality of shielding plates having different sizes, positions, numbers, and the like, and to selectively use them according to the type of crop, ridge shape, season, and the like. Or, when the worker uses a cutter knife or the like as appropriate according to the purpose,
By providing the opening, it is possible to respond flexibly according to the condition of the ridge, the type of crop, and the like, and the versatility is significantly increased. In this case, the shielding plate is preferably an easy-to-handle plastic plate, particularly preferably an acrylic plate.

[0009] The size of the shielding plate is arbitrary as long as the spray control opening of the shutter can be closed or opened. The thickness is also not particularly limited, but in the case of an embodiment that is opened at the time of work, since work is difficult if it is too thick, usually,
A range of 0.5 to 2.0 mm is appropriate.

[0010] The mounting of the shielding plate, in view of work efficiency,
It is preferable to provide an appropriate insertion portion below the hopper, and to attach the hopper simply by inserting it. However, known locking means may be provided if necessary.

[0011] Also, provided at the bottom of the hopper of the present invention,
The power source for the pair of helical shafts rotating in opposite directions may be either motor or wheel rotation, such mechanisms being known to those skilled in the art. As shown in the following examples,
A helical shaft that rotates in the same direction as the axle and a helical shaft connected to the axle via a gear so as to rotate in the opposite direction can be used. It is convenient to attach a blade member usually used for the same purpose to the peripheral wall of the helical shaft, so that the fertilizer and the like remaining on the bottom of the hopper can be uniformly and completely sprayed.

[0012] Although the present specification describes an improvement in a manual fertilizer application and a dispensing machine, in view of the spirit of the present invention, a shielding plate having an opening is a fertilizer and / or a combination of a hopper and a shutter. Those skilled in the art will readily understand that the present invention can be applied to general dispensing machines, and when applied to them, the same effects as those of the present invention can be obtained. Therefore, the present invention also includes such a non-manual fertilizer and dispenser.
