Description

本発明は、機体に対し略横方向に張架されて野菜・花等の苗を横方向に運ぶ無端状搬送ベルトを備えた移植機の苗搬送装置に関するものである。   The present invention relates to a seedling transport device for a transplanting machine, which is provided with an endless transport belt that is stretched substantially laterally with respect to the machine body and transports seedlings such as vegetables and flowers in the lateral direction.

従来の移植機として、まず、特許文献１及び特許文献２に記載されたものを例示する。この移植機は、ポット苗箱から押し出された横一列の野菜・花苗を植付装置に供給する苗搬送装置を含んでおり、該搬送装置により供給された野菜・花苗は植付装置により圃場表面に連続的に移植されるようになっている。苗搬送装置は、一対のプーリに巻き掛けられて機体に水平に張架された無端状搬送ベルトを含んでおり、該搬送ベルトに野菜・花苗全体を載せ横方向に搬送するようになっている。搬送ベルトは、該幅方向に向けて供給される野菜・花苗全体を確実に載せることができるように幅広に形成されている。   As conventional transplanters, first, those described in Patent Document 1 and Patent Document 2 will be exemplified. This transplanter includes a seedling transport device that supplies a row of vegetables and flower seedlings extruded from a pot seedling box to a planting device, and the vegetables and flower seedlings supplied by the transport device are It is designed to be transplanted continuously. The seedling conveying device includes an endless conveying belt that is wound around a pair of pulleys and stretched horizontally around the machine body, and the entire vegetable / flower seedling is placed on the conveying belt and conveyed in the lateral direction. . The conveyor belt is formed wide so that the whole vegetables and flower seedlings supplied in the width direction can be surely placed.

ところで、この種の移植機は一般に降雨時を避けて使用されるように設計されており、水分を含む土が各部に付着すると誤作動の原因となる。そして、野菜・花苗のポットの土は水分を含んでおり、この土が崩れたものが搬送ベルトに付着・堆積して誤作動することが多いという課題がある。   By the way, this kind of transplanter is generally designed to be used avoiding rain, and if soil containing moisture adheres to each part, it causes a malfunction. And the soil of the vegetable and flower seedling pot contains moisture, and there is a problem that the broken soil often adheres and accumulates on the conveyor belt and malfunctions.

また、搬送ベルトの外周には野菜・花苗を所定間隔に分割配置する突起があり、これにポットの土が付着して埋まると野菜・花苗の間隔が狂って、植付間隔が乱れるという課題もある。   In addition, there is a protrusion on the outer periphery of the conveyor belt that divides and arranges vegetables and flower seedlings at a predetermined interval, and if the pot soil adheres to it and fills it, the interval between the vegetables and flower seedlings goes wrong and the planting interval is disturbed is there.

また、ポットの土の堆積を防止するために、例えば金属片のスクレーパーや、ブラシ等を設け、これで搬送ベルトに付着した土を掻き取ることも考えられる。しかし、ポットから毎回少しずつ崩れた土には野菜・花苗の下葉の枯れたものやヒゲ根の切れたもの等が混じっているので、スクレーパーやブラシ等で掻き取った土がダンゴ状になり易く、このダンゴ状の土が搬送ベルトの回転を妨害するという課題がある。   Further, in order to prevent the accumulation of soil in the pot, for example, a scraper of metal pieces, a brush, or the like may be provided to scrape off the soil adhering to the transport belt. However, the soil that has crumbled little by little from the pot is mixed with things that have fallen under the leaves of vegetables and flower seedlings, and those that have had their mustache roots cut out. There is a problem that this dango-like soil obstructs the rotation of the conveyor belt.

そこで、特許文献３記載の移植機における苗搬送装置では、図４の側断面図に示すように、これらの課題を解決し、搬送ベルト６０へのポットＰの土の堆積を防止するために、搬送ベルト６０の苗載置に妨害とならない側に、該搬送ベルト６０の外周面に向けて空気Ａを噴出する外側ノズル７８と、該搬送ベルト６０の内周面に向けて空気Ａを噴出するノズル７９とを設けている。これにより、ノズル７８，７９から噴出される空気で、土を吹き飛ばすとともに、土を乾燥させることにより土が付着し難くするようにしている。   Therefore, in the seedling conveying device in the transplanter described in Patent Document 3, as shown in the side sectional view of FIG. 4, in order to solve these problems and prevent the accumulation of the soil of the pot P on the conveying belt 60, An outer nozzle 78 that ejects air A toward the outer peripheral surface of the conveyor belt 60 and an air A toward the inner peripheral surface of the conveyor belt 60 on the side that does not interfere with the seedling placement of the conveyor belt 60. A nozzle 79 is provided. Thus, the air blown off from the nozzles 78 and 79 blows away the soil, and the soil is dried to make it difficult for the soil to adhere.

ところが、特許文献３記載の苗搬送装置のように、搬送ベルト６０に付着した土を吹き飛ばすには、高圧の空気Ａを吹き付ける必要があり、高圧の空気Ａの供給源としの高圧エアポンプや高圧エアを充填したタンク等を移植機の機体に備える必要があり、コストが掛かるとともに、機体が重くなって走行性や操縦性等が低下するという課題がある。   However, as in the seedling conveying device described in Patent Document 3, in order to blow off the soil adhering to the conveying belt 60, it is necessary to blow high-pressure air A. A high-pressure air pump or high-pressure air as a supply source of high-pressure air A is required. It is necessary to equip the body of the transplanter with a tank or the like filled with, and there is a problem that the cost increases and the body becomes heavier and travelability and maneuverability are reduced.

The seedling P is held in the receiving groove 13. Subsequently, the seedling receiving base 12 that has received the seedling P is rotated downward while inverting the seedling P in the reverse direction. At this time, the seedling receiving groove 13 of the jumping member 18 of the root portion Pa of the seedling P is first reached. Go through position. As a result, the seedling P is pushed out of the seedling receiving groove 13 and falls onto the conveying belt 20 of the lower seedling conveying device 5. In the seedling receiving groove 13 of the seedling receiving base 12 of this example, a portion 16 that forms an inner peripheral surface that receives the outer peripheral surface of the root portion Pa of the seedling P is made of resin, and the protrusion 14 that bites into the outer peripheral surface is made of metal. It has become. In this example, an edge portion of the metal plate 15 that extends in the pushing direction is used as the protrusion 14, and the metal plate 15 is attached to a portion 16 that forms the inner peripheral surface by screws 17 in a replaceable manner. ing. The ridges 14 in the seedling receiving platform 12 are easy to wear because they bite into the root portion Pa of the seedling P. Conventionally, the inner peripheral surface of the seedling receiving groove 13 and the ridges 14 are integrally formed of resin. Replacement was necessary. According to the structure of this example, since the protrusion 14 is metal, it is hard to wear | wear and can reduce the effort and cost of a maintenance. And when the protrusion 14 is worn out, it is only necessary to replace the metal plate 15 having the protrusion 14.
