[0001]
[Technical field to which the invention belongs]
The present invention mainly relates to a simple human-powered fertilizer application machine.
[0002]
[Background Art and Problems to be Solved by the Invention]
Stores fertilizers and pesticides (hereinafter referred to as fertilizer, etc.) in a hopper equipped with wheels and a handle, and operates a shutter with a spraying adjustment port for adjusting the open / closed state of multiple spraying ports opened in the bottom wall In addition, a human-powered fertilizer and a medicine applicator are known for spraying fertilizer and agricultural chemicals that have passed through the spraying port and the control port on the ground while traveling in the field.
In the case of this type of fertilizing and dispensing machine, it is configured to adjust the spraying amount of fertilizer, etc. by shifting the position of the spraying port on the bottom wall of the hopper and the spraying control port on the shutter. If it is closed, fertilizer may be clogged and it may not fall uniformly. In addition, since the position of the spraying port on the bottom wall is unchanged, it has been forced to spray even the unnecessary portions. Thus, in the conventional fertilizer application and the medicine applicator, there is no degree of freedom in adjusting the application amount and application position of fertilizer and the fertilizer and the like may be wasted. Also, in this type of fertilizer and drug applicator, fertilizers and pesticides are usually moved by rotating the spiral shaft provided at the bottom of the hopper and sequentially moved by the blade members on the peripheral wall. In some cases, spraying could not be made evenly.
[0003]
The present invention provides a human-powered fertilizer application machine capable of appropriately adjusting the amount and position of fertilization / medicine according to the situation, and capable of always uniformly spraying regardless of the shape and remaining amount of fertilizer, etc. The issue is to provide.
[0004]
[Means for solving the problems]
In order to solve the above-mentioned problems, the present invention provides a fertilizer and a medicine applicator in which a plurality of spray ports are provided at the bottom of the hopper, and a pair of helical shafts that rotate in opposite directions are arranged at the bottom of the hopper. providing a shutter in which a spray regulating opening with equal distribution opening interval movably, providing at least one shielding plate having an opening, fertilization and Seyaku machine is characterized in that detachably attached to the hopper downwardly To do. According to the fertilizing and dispensing machine of the present invention configured as described above, the fertilizer and the like can be uniformly distributed on the ground by rotating the helical shafts below the hopper in opposite directions. In addition, by moving the shutter below the hopper, the relative position of the spraying adjustment port with respect to the spraying port is changed, the switching state of the spraying port is switched, and a shielding plate having a desired size and number of openings is used in combination. Thus, the number of spraying ports in the open state can be adjusted.
[0006]
The “shielding plate” in the fertilizing and dispensing machine of the present invention is a thin plate having a desired size and number of openings or capable of being opened. Under the hopper of the fertilizer application and medicine applicator of the present invention, there is provided an insertion portion into which the shielding plate can be detachably inserted. The spout opening will open in response to the movement of the shutter. The position of the insertion portion may be either under the shutter or between the hopper bottom and the shutter.
[0007]
The material of the shielding plate is not particularly limited as long as it does not contradict the object of the present invention, and examples thereof include plastic, metal, glass, etc., but plastic that is flexible and elastic and easy to handle is preferable. . An acrylic resin is preferable as an example.
[0008]
The size, number, position, etc. of the opening of the shielding plate can be variously set according to the purpose. For the purpose of the present invention, it is convenient to prepare in advance a plurality of shielding plates with different sizes, positions, numbers, etc., and use them according to the type of crop, the shape of the culm, the season, etc.
Alternatively, if an operator appropriately provides an opening for use with a cutter knife or the like according to the purpose, it can respond flexibly according to the state of the culm, the type of crop, etc., and versatility is significantly increased. . In this embodiment, the shielding plate is preferably a plastic plate that is easy to handle, and an acrylic plate is particularly preferable.
[0009]
The size of the shielding plate is arbitrary as long as it can close or open the spraying adjustment port of the shutter. The thickness is not particularly limited, but in the case of an embodiment in which the thickness is opened during work, the work is difficult if the thickness is too thick. Therefore, the range of 0.5 to 2.0 mm is usually appropriate.
[0010]
In consideration of work efficiency, the shielding plate may be attached by providing an appropriate insertion portion below the hopper and simply inserting it. However, known locking means may be provided as necessary.
[0011]
Further, the power source of the pair of helical shafts provided in the hopper bottom of the present invention and rotating in opposite directions may be either a motor or a wheel, and such a mechanism is known to those skilled in the art. As shown in the following embodiments, a spiral shaft that rotates in the same direction as the axle and a spiral shaft that is coupled to the axle so as to rotate in the opposite direction via a gear can be used. Note that it is advantageous to attach a blade member usually used for the same purpose to the peripheral wall of the spiral shaft because uniform and complete spraying of the fertilizer remaining on the bottom of the hopper can be performed.
[0012]
In addition, in this specification, although the improvement in human-powered fertilization and a medicine applicator is described, in light of the gist of the present invention, a shielding plate having an opening is a fertilizer and / or a general medicine applicator composed of a combination of a hopper and a shutter. Those skilled in the art should easily understand that the same effects as those of the present invention can be obtained when applied to them. Therefore, the present invention includes such a non-human-powered fertilizer application machine.
