本発明は、粒状肥料を肥料タンクから設定量ずつ繰出し
て作溝器に落下供給する繰出し装置を設けた施肥装置に
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fertilization device equipped with a feeding device that feeds granular fertilizer in set amounts from a fertilizer tank and drops it into a furrower.
上記施肥装置において、従来、例えば実開昭６０〜５７
９１８号公報に示されるように、肥料タンクの貯留空間
底部に選別具としてのコイルハネを設けると共に、タン
ク内の粒状肥料に混在する粉体物をコイルハネが選別漏
下させるように構成することにより、破砕のために粉体
化した肥料を作溝器等に付着しないように除去すること
を可能にされていた。In the above-mentioned fertilizer application device, conventionally, for example,
As shown in Publication No. 918, by providing a coil blade as a sorting tool at the bottom of the storage space of the fertilizer tank and configuring the coil blade to sort out and leak powder mixed in the granular fertilizer in the tank, It was possible to remove fertilizer that had been turned into powder due to crushing without adhering to furrowers, etc.
従来装置の場合、肥料が多量にまとまって存在すると共
に肥料流れが比較的少ない箇所で選別具が作用すること
から、粉体化肥料の除去効率が悪くなることがあった。In the case of conventional devices, the removal efficiency of powdered fertilizers sometimes deteriorated because a large amount of fertilizer is present in a lump and the sorting tool acts at a location where there is relatively little fertilizer flow.
本発明の粉体化肥料の除去が精度よくできると共に繰出
し装置による繰出し量の計測が有利にできる装置を提供
することにある。It is an object of the present invention to provide a device that can remove powdered fertilizer with high precision and can advantageously measure the amount fed out by a feeding device.
本発明の特徴構成は、冒記した施肥装置において、前記

繰出し物の全てを前記容器に落下させる作用解除状態と
に切換え自在に備えると共に、前記容器に貯留物量表示
用の目盛りを備えてあることにある。そして、その作用
及び効果は次のとおりである。The characteristic configuration of the present invention is that, in the above-mentioned fertilization device, it acts on the material fed out from the feeding device to cause the powdery material of the material to leak out, and also guides and falls the granular fertilizer to the furrower side. A powder material sorting and recovery device is provided which has a sorting tool and a container for receiving and storing leaked powder material from the sorting tool, and the sorting tool is in an operating state and the powder material fed out from the feeding device is controlled. The device is capable of being switched freely to a deactivation state in which everything is dropped into the container, and the container is provided with a scale for displaying the amount of stored materials. The functions and effects thereof are as follows.
繰出し装置から設定量ずつ繰出され、少量でかつ流れが
大である状態の肥料に選別具が作用して、粉体化肥料を
選別して容器に漏下させる。The sorting tool acts on the fertilizer that is dispensed in a set amount from the dispensing device and flows in a small amount and in a large flow, thereby sorting out the powdered fertilizer and causing it to leak into the container.
選別具を作用解除状態に切換えると、繰出し装置からの
繰出し肥料が容器に落下し、繰出し肥料を容器をして回
収でき、前記目盛りを利用することにより回収肥料の量
を測定し、この測定量に基ついて繰出し装置による単位
時間や単位作動回数当りの繰出し量を計測できる。When the sorting tool is switched to the deactivated state, the fertilizer fed out from the feeding device falls into the container, and the fed fertilizer can be collected in the container, and the amount of recovered fertilizer is measured using the scale, and this measured amount is Based on this, the amount of feeding by the feeding device per unit time or unit number of operations can be measured.
選別具が少量で流れの大なる状態の肥料に作用すること
により、粉体化した肥料の除去が精度よくされるように
なり、粉体化肥料の付着に起因する詰りか発生しにくく
て能率よく作業できるようになった。Since the sorting tool acts on a small amount of fertilizer in a large flow state, powdered fertilizer can be removed with high precision, making it more efficient as it is less likely to cause clogging due to adhesion of powdered fertilizer. I can now work better.
粉体化肥料回収用の容器を繰出し置針測用に利用できる
ために、繰出し置針測がそのための容器を特別に準備し
なくとも、かつ、容器を作溝器の下にセントする等の特
別な手間を掛けなくてもでき、繰出し量調節が用具面か
らも手間面からも有利にできるようになった。Because a container for collecting powdered fertilizer can be used for feeding out and measuring the needle position, there is no need to prepare a special container for feeding out and measuring the needle, and special measures such as placing the container under the furrower are not required. It can be done without much effort, and the amount of feeding can now be adjusted advantageously in terms of both equipment and labor.
