Description

The invention according to claim 1 is provided with a seedling planting portion on the rear side of the vehicle body via an elevating link device, and the seedling planting portion takes out the seedling and plants it behind the lower end of the seedling mounting portion that inclines backward and downward. The planting device is mounted in parallel with the planting body in correspondence with the planting line, and a planting spindle that is commonly transmitted to these side-by-side planting devices is provided in the vicinity of the front end, and the planting device at the outer end is installed in the planting spindle. In addition, in the seedling transplanter configured to be foldable inward, a lock arm is provided that forms a restricting portion for fixing the foldable outer portion of the planting main shaft that is transmitted to the planting device at the outer end to the deployment support position. The lock arm includes a shaft support portion that pivotably supports the range where the restricting portion extends from the fixed position to the release position, and the restricting portion and the shaft support portion are vertically distributed to the front side of the planting spindle at the fixed position. It is characterized by having arranged. The said lock arm is arrange | positioned facing the open space of the front side of a planting main axis | shaft under the seedling mounting part.

According to a second aspect of the present invention, in the configuration of the first aspect, the lock arm is provided with a gripping part for swinging operation which is bent so as to protrude from the restricting part to the front side of the machine body at a fixed position. To do. In the lock arm, an operating force is efficiently applied to the restricting portion via a grip portion close to the restricting portion.
According to a third aspect of the present invention, when the planting device (200) at the outer end is folded inward, the float (210) is controlled to a position where the planting depth is the deepest. A seedling transplanting machine according to claim 1 or claim 2.
According to the invention of claim 4, the rear part of the seedling planting part (4) is provided with an proximity sensor (251) for detecting a rear object, and based on the detection of the proximity sensor (251), the seedling planting part (4) The seedling transplanter according to any one of claims 1 to 3, wherein a control unit (C) for stopping operation and vertical movement is provided.

The seedling transplanting machine 1 has a configuration for reducing the left and right widths of the seedling planting unit 4 during transportation and storage. First, the structure which folds the right-and-left end part of the seedling mounting part 80 is demonstrated (refer FIGS. 6-10).

The filter 160 used in the cleaning (spraying) apparatus is composed of upper and lower double filter screens 161 and 162, the lower filter screen 161 is fixed, and the upper filter screen 162 is attached to the lower end of the impeller 163. The shaft is pivoted around the shaft core 164 so as to freely rotate, and is swung with a force of entering water. Even in the filter according to the double filtration network, will be clogged with dust filter, the flow of water is poor in the middle of use. As in this example, according to the above configuration, clogging of the filter can be prevented by the rotation of the upper filtration net that rotates with the momentum of the incoming water and the accompanying swirling flow of water.

Claims (4)

A seedling planting part (4) is provided on the rear side of the vehicle body (2) via an elevating link device (3), and the seedling planting part (4) is behind the lower end of the seedling mounting part (80) that is inclined rearwardly downward. The planting device (200) for taking out and planting the seedlings is mounted in parallel with the machine body corresponding to the planting line, and the planting spindle (70) that is commonly transmitted to these side-by-side planting devices (200) is mounted. In the seedling transplanting machine, which is provided in the vicinity of its front end and configured to be able to fold the planting device (200) at the outer end together with the planting main shaft (70),
Lock arm (221) formed with a restricting portion (221a) for fixing the foldable outer portion (70B) of the planting main shaft (70) transmitted to the planting device (200) at the outer end to the unfolding support position. The lock arm (221) includes a shaft support portion (223) that pivotally supports a range (A) in which the restricting portion (221a) extends from the fixed position to the release position. A seedling transplanting machine characterized in that the part (221a) and the shaft support part (223) are arranged in the vertical direction on the front side of the planting spindle (70).   The said lock arm (221) is provided with the holding | grip part (224) for rocking | fluctuation operation formed by bending so that it may protrude from the control part (221a) to the body front side in a fixed position. Seedling transplanter. The structure according to claim 1 or 2, wherein the float (210) is controlled to a position where the planting depth is deepest when the planting device (200) at the outer end is folded inward. Seedling transplanter. An approach sensor (251) for detecting a rear object is provided at the rear part of the seedling planting part (4), and the operation and vertical movement of the seedling planting part (4) are stopped based on the detection of the proximity sensor (251). The seedling transplanter according to any one of claims 1 to 3, further comprising a control unit (C).
