Description

  The present invention relates to a configuration of a local application machine for vertical application that simultaneously forms a koji for growing leafy vegetables such as Chinese cabbage and cabbage and sprays fertilizers and agricultural chemicals.

In recent years, there has been a demand for a local spreader aimed at reducing the production cost and environmental load in vegetable crops, and a number of local fertilizers and local spreaders corresponding to it have been proposed. For example, Japanese Patent No. 3586677 (Patent Document 1) is known as a vertical spreader for cultivating this type of leafy vegetables. This known document includes "a machine, a mission device provided in the machine, a tilling rotary provided rotatably on the machine and driven to rotate by an output from the mission device, and a tilling rotary provided on the machine. A sprinkling device for vertically forming the cultivated soil cultivated in, and a spraying device for locally spraying the material to be sprinkled on the cultivated soil that is sprinkled and formed by this sprinkled compact, A hopper provided in the machine body for containing the object to be dispersed, a derivation body provided in the hopper for deriving the object to be dispersed and contained in the hopper, and provided in a derivation part of the derivation body and derived from the derivation body A spraying body for locally spreading the spread material to be cultivated in the cultivated soil, which is formed upright by the paddy compact, and the spraying body is arranged at the lower end of the spraying body in the traveling direction of the spraying body. To the rear The soil spray flap protrudes toward the rear at the upper edge of the spraying port, and the position where the material to be sprayed is sprayed locally at the lower edge of the spraying port is leveled horizontally. A technique of “a vertical spreader characterized by forming a horizontal ground surface” is disclosed.
Japanese Patent No. 3558677

  In the configuration of the above-described vertical fertilizer, the spreader continuously and reliably forms the cocoon in the cocoon-molded body in a state in which the material to be spread is continuously sprayed on the local position of the cocoon. However, the sprayed state is a belt state or a streak-like (string-like) state, and it is arranged in a single point when viewed from the heel cross section.

  Therefore, after planting leafy seedlings, etc., when the root grows directly in contact with the fertilizer, the timing and timing of absorbing the fertilizer is not constant, and when it comes into contact with a single-point fertilizer early or late There is a problem that the effect of fertilizer is different when it comes into contact with the fertilizer, and if the roots at the time of seedling touch the one-piece solid fertilizer, the problem of burnt fertilizer may be considered. Furthermore, when it is desired to spray agricultural chemicals or the like in addition to fertilizers in the soil, there is a problem that when applied in a lump form, the medicinal effect is diminished or the roots in contact with the lump cause phytotoxicity.

  In addition, when it is desired to apply several types of fertilizers and pesticides in a mixed manner, there is a problem in that work efficiency is poor because it is necessary to perform the application process separately. Accordingly, an object of the present invention is to provide a vertical and simultaneous local mixing application machine capable of simultaneously applying several types of application at the same time as forming a cocoon in which a crop to be planted can grow well.

In order to solve the above-mentioned problems, a machine body provided with a tractor mounting part on the front side, a cultivating body provided at a lower part on the front side of the machine body, a hopper for storing an application provided above the cultivator body, and an applied product falling from the hopper A local application device having a lead-out pipe for guiding a plurality of applications simultaneously, a cocoon molded body provided behind the cultivating body, and the local application device provided between the cultivated body and the cocoon molded body A stirrer that partially mixes only the root group region of the planted crop with the cultivation soil by the stirring claws arranged so as to stir a range narrower than the width of the ridge formed by the cocoon molding. The local application device includes a single hopper that accommodates an object to be applied, and a shutter device that adjusts the amount of application object fall provided at the bottom of the hopper, Application dropped from the shutter device It is a local application device that is provided with spraying blades that rotate and scatter objects in the horizontal direction, thereby spraying on a distribution case having a plurality of outlet pipes and applying to the central part of the basket by the outlet pipes. In order to simultaneously apply an object, a vertical and simultaneous local mixing applicator is provided in which a stirring blade capable of mixing a plurality of objects to be applied by rotating in the hopper is provided in the hopper .

  According to the configuration of the present invention, the applied material to be applied is not limited to fertilizers but can be used for soil improvers and agricultural chemicals, and when growing locally, such as leaf vegetables, roots for growing leaf vegetables etc. Since the required amount of the applied material is mixed and stirred with the cultivated soil over the upper and lower layers in the range of the group area, in the case of fertilizer application, the roots can absorb the fertilizer content constantly with the growth of leaf vegetables. it can. In addition, because the planted crops are stirred up and down with the width of the root group, the growth of the leafy vegetables is stable without suffering from fertilizer burns or chemical damage, even though the minimum necessary application is locally applied to the cultivation straw. In addition, it is economical because wasteful application is not performed outside the root area, and the mixed and stirred application part is confined inside the ridge, so that the fertilizer and pesticides can be prevented from flowing out, and environmental pollution can be minimized. .

  In addition, the local application device can apply multiple applications at the same time, so it is easy to apply several types of fertilizers at the same time, or to apply fertilizers and pesticides at the same time. In the case of the device, it is possible to perform more accurate local application by mixing a plurality of products to be applied in advance, without the need to provide a storage hopper for each type of application to be applied, They can be mixed and applied at one time without limiting the type of application desired.

  In addition, the local application device constitutes an agitator that moves while stirring in one direction on a U-shaped ridge, and the application object can be moved to the adjacent ridge at the end in the transfer direction by combining them in opposite directions. If a structure that stirs by continuously circulating a stirring material is provided, a smooth flow of the applied material is formed, enabling high-speed stirring, and discharging and spraying directly from the bottom surface of the U-shaped bowl of the stirring unit Therefore, the mixing action can be smoothly mixed and sprayed with little compression action and bridge of the mixed application, and the hopper part can be configured in a direction in which the longitudinal direction is orthogonal to the aircraft traveling direction. Can be provided above.

  In addition, a single hopper that accommodates the object to be applied is rotated inside the hopper to mix the object to be applied, dropped from the shutter at the bottom of the hopper, and scattered into the distribution case by the spraying blade rotating at the lower side to lead out the pipe. Thus, in the case of a local application device configured to be applied locally, the overall configuration is simplified, and a mixed local application device having a lightweight configuration can be provided.
