Description

【０００１】
【発明の属する技術分野】
本発明は苗載台及び植付爪を備えて連続的に苗植作業を行う田植機にあって、植付条の側方に施肥を同時に行う田植機に関する。
【０００２】
【発明が解決しようとする課題】
従来、施肥ホッパ内の肥料を施肥位置まで空気搬送する搬送ホースなどに肥料の粉が付着するのを防止するために、繰出ロールや目皿などを有する繰出部の下流側に粉だけを通過させる粉取り網を設け、粒状の肥料は搬送ホースに、また粉状の肥料は粉容器にそれぞれ分離して排出させるようにした手段がある。
【０００３】
しかし乍らこのような繰出部の下流側に粉取り網など設ける手段の場合、繰出部では粉の除去が行えないため繰出ロールや目皿などに粉が付着或いは堆積して、施肥量が減少したり繰出ロールや目皿などに詰まりが発生する不都合があった。
【０００４】
【課題を解決するための手段】
したがって本発明は、走行機体に、植付部を装着するとともに、この植付部における施肥位置に肥料を散布する施肥機を装着して成り、前記施肥機を、施肥ホッパと、この施肥ホッパ内の肥料を送風機からの空気流により前記施肥位置まで搬送する手段とで構成して成る田植機において、前記施肥ホッパのうち当該施肥ホッパ内の肥料が流下する底部傾斜面に粉排出口を形成し、肥料のうち粉になった肥料が通過する粉分離網と、この粉分離網の外側を囲う粉排出部材とを備え、前記施肥ホッパの前後巾内に前記粉排出部材を配置し、前記送風機における吸い込み側に前記粉排出部材を連通する構成にし、前記粉排出部材の接続口と前記粉排出口との間に前記粉分離網を介設させ、前記施肥ホッパの外側面に、前記粉分離網と前記粉排出部材とを、ボルトにて締結することで取外し自在に固定させるように構成したことにより、前記施肥ホッパ内からその底部における繰出部に肥料が供給されるまでの以前に肥料のうち粉になった肥料を粉分離網にて除去し、常に適正量の粒状肥料を繰出部から繰出して、施肥精度を向上させるものである。
【０００５】
この場合、前記粉分離網を、前記施肥ホッパのうち当該施肥ホッパ内の肥料が流下する底部傾斜面に設けたことにより、前記施肥ホッパ内での肥料の流れを妨げることなく、スムーズに流下させる粒状肥料中から肥料粉を良好に分離して排出させることができる。
【０００６】
さらに、前記粉分離網の外側を囲う前記粉排出部材を前記送風機における吸い込み側に連通したことにより、送風機の吸引力を前記粉分離網に作用させて粉を吸引排出させることによって、粉の除去効果を向上させると共に、送風機の送風力で搬送される粒状肥料に肥料粉を混入して施肥することによって、肥料粉を無駄なく有効利用し、また肥料粉を飛散させて機体に錆を発生させるなどの不都合も解消される。
【０００７】
特に、前記粉排出部材を、前記施肥ホッパにおける前後巾内に配設する構成にしたことにより、前記粉排出部材を施肥ホッパの前後巾内にコンパクトに配備させ、施肥機の小型軽量化を可能とさせて、田植機体に対しこの施肥機を容易且つ簡潔に装備させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a rice transplanter that includes a seedling stage and a planting claw and continuously performs seedling planting work, and relates to a rice transplanter that performs fertilization simultaneously to the side of a planting strip.
[0002]
[Problems to be solved by the invention]
Conventionally, in order to prevent the fertilizer powder from adhering to a transport hose that transports the fertilizer in the fertilizer hopper to the fertilizer position, only the powder is passed to the downstream side of the feed section having a feed roll and a pan. There is a means in which a powder net is provided, and granular fertilizer is separated into a transport hose and powdered fertilizer is separated into a powder container.
[0003]
However, in the case of means for providing a dust removal net or the like downstream of such a feeding part, powder cannot be removed at the feeding part, so that powder adheres to or accumulates on the feeding rolls and eye plates, thereby reducing the amount of fertilization. And there is a disadvantage that clogging occurs in the feeding roll and the eye plate.
[0004]
[Means for Solving the Problems]
Therefore, the present invention comprises a traveling body mounted with a planting part and a fertilizer spreader for spraying fertilizer at a fertilization position in the planting part. The fertilizer is divided into a fertilizer hopper and a fertilizer hopper. In the rice transplanter constituted by means for conveying the fertilizer of the fertilizer to the fertilization position by the air flow from the blower, a powder discharge port is formed on the inclined bottom surface of the fertilizer hopper where the fertilizer in the fertilizer hopper flows down. , a powder separation network fertilizer became out powder fertilizer passes, and a powder discharge member surrounding the outside of the powder separation network, placing the powder discharge member before and after the width of the fertilizer hopper, the blower The powder discharge member is connected to the suction side of the powder discharge member, the powder separation net is interposed between the connection port of the powder discharge member and the powder discharge port, and the powder separation is performed on the outer surface of the fertilizer hopper. Net and powder discharge member And by constructing such removal is securable by fastening with bolts, the fertilizer from fertilization hopper to the feeding section at the bottom became floured fertilizer prior to being supplied fertilizers It is removed by a powder separation net, and an appropriate amount of granular fertilizer is always fed out from the feeding portion to improve fertilization accuracy.
[0005]
In this case, by providing the powder separation net on the bottom inclined surface where the fertilizer in the fertilizer hopper flows down among the fertilizer hopper, the powder separation net flows smoothly without interfering with the flow of the fertilizer in the fertilizer hopper. Fertilizer powder can be well separated and discharged from the granular fertilizer.
[0006]
Furthermore, by removing the powder by sucking and discharging the powder by causing the suction force of the blower to act on the powder separation net by communicating the powder discharge member that surrounds the outside of the powder separation net with the suction side of the blower. In addition to improving the effect, fertilizer powder is mixed and fertilized into the granular fertilizer conveyed by the blowing power of the blower, so that the fertilizer powder can be used effectively without waste, and the fertilizer powder is scattered to generate rust on the aircraft. Inconveniences such as are also eliminated.
[0007]
In particular, the powder discharge member is arranged in the front and rear width of the fertilizer hopper, so that the powder discharge member can be compactly arranged in the front and rear width of the fertilizer hopper, and the fertilizer can be reduced in size and weight. by a, it is possible to equip this fertilizer machine easily and concisely to planting body.
