Description

【考案の詳細な説明】 従来、施肥機は植付条数と同じ本数の施肥管を
備えていて、各施肥管毎に検出器付きの導管で肥
料を施肥管に送つていた。[Detailed description of the invention] Conventionally, a fertilizer applicator has been equipped with the same number of fertilizing pipes as the number of planting rows, and each fertilizing pipe has a conduit equipped with a detector to send fertilizer to the fertilizing pipes.

る欠点があつた。 In other words, multiple detectors are lined up at the front of the control section, and as fertilizer continues to be applied, the fluidity of the fertilizer deteriorates and one part of the fertilization pipe or conduit becomes clogged, causing the operator to be unable to see forward. Since a plurality of conduits are carefully monitored at the same time, the above-mentioned clogging is detected too late and proper fertilization cannot be applied, resulting in poor growth of seedlings in that area.

徴とするものである。 The present invention can quickly and accurately detect the aforementioned fertilizer clogging, and also prevents the detector from being damaged due to incorrect operation in systems where the engine's recoil starter is operated from the control unit. However, the aim is to provide a fertilization detection device for mobile agricultural machines that can prevent such accidents.The fertilization device is attached to the machine body, and a sensor is installed at the front of the control section to monitor the flow of fertilizer. The mobile agricultural machine is equipped with a detector that allows the fluid level height to change accordingly and to visually check the flow state, and is characterized in that a substantially horizontal reference rod is provided on the control section side of the detector.

The upper parts of the stands 17, 17 and the upper part of the seedling stand 23 of the planting device 1 are approximately equal to each other, so when the seedlings placed on the auxiliary seedling stand 17 are pulled out together with the seedling box to replenish the seedling stand 23, As shown in FIG. 2, it is not only easy to pull out the seedling box from the auxiliary seedling stand 17, but also to hang the pulled out seedling box between the auxiliary seedling stand 17 and the support frame 18 or between the support frame 18 and the drawing stand 23. The preliminary seedlings can be supported on the seedling stand 23 in this state.

者は第８図に示すようにそれを目で基準杆１９ａ
を目安にして発見し、詰りの原因を除去する。 In such a case, the liquid level of the paste fertilizer in the detector 11 communicating with the fertilizing pipe 12 rises, and the operator visually checks it with the reference rod 19a as shown in FIG.
Use this as a guide to discover and remove the cause of the clog.

また、肥料タンク９内が空になつた時は検出器
１１内の液面が低くなるので、これを前述と同様

る。 The present invention is a mobile agricultural machine in which a fertilizer applicator is attached to the machine body as described above, and a detector is installed at the front of the control section to change the liquid level depending on the flow condition of the fertilizer and to visually check the flow condition. Since a substantially horizontal reference rod is provided on the control side of the detector, changes in the liquid level within the detector can be detected instantly and accurately by visually checking the reference rod in comparison with the detector. Therefore, when a clogging occurs in a fertilizing pipe or conduit or when a fertilizer tank becomes empty, appropriate measures can be taken quickly without missing an opportunity.
