Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides mat-like seedlings that are reloaded on a seedling tray that is reciprocated with a constant stroke, along a lower end row that protrudes below the lower edge of the seedling tray. This invention relates to a seedling shielding device configured to sequentially take out and place seedlings one by one using a planting claw that circulates up and down in synchronization with the movement of the seedling platform at a fixed position in the direction of movement of the seedling platform.

The above-mentioned seedling shield attaching device needs to receive the lower end face and the lower end bottom face of the matted seedlings to prevent the matted seedlings from sliding down from the box frame portion of the sloping seedling stand, and It is necessary to release the receiving action only near the point where the hammered claw passes in order to take out the seedlings.

For this reason, in the past, a seedling receiving frame along the moving direction of the seedling platform, which was closed only near the area where the nails pass through for seedling extraction, was fixed at a position near the green at the lower end of the horizontally moving box frame. However, in this case, the lower end of the mat-like seedlings sliding on the seedling receiving frame is easily deformed and damaged due to sliding resistance caused by the sliding saddle with the seedling receiving frame. , there is a tendency to become addicted to it, which leads to problems such as the size of individual seedlings being uneven. In addition, the seedling receiving frame has to receive and support the seedlings over the entire range of the horizontal movement stroke of the box frame portion that accommodates the mat-like seedlings, so it is quite long considering the entire stroke. There is also a drawback that the presence of the seedling receiving frame increases the width of the entire device.

The present invention changes the viewpoint of the seedling receiving frame in which an opening for taking out seedlings is formed at a fixed position in order to allow the passage of a shield claw that circulates up and down at a fixed position on the machine body.
This technology overturns the conventional fixed idea that seedlings can be divided into individual plants by moving the box frame part that accommodates the mat-shaped seedlings laterally relative to the fixed seedling receiving frame. The structure of the seedling stand has been improved so that the seedlings can be divided into individual plants using the claws with a shield while the stopper frame moves laterally with the box frame, and the sliding resistance of the lower end of the seedlings mentioned above has been improved. The purpose is to eliminate the troubles associated with this and the drawbacks that lead to an increase in the size of the entire device.

The characteristic structure of the present invention for achieving the above object is as follows:
The seedling stand includes a box frame portion that accommodates the mat-shaped seedlings so as to be movable toward the lower end side, and a rake that receives the lower end surface and lower end bottom surface of the mat-shaped seedlings that protrude downward from the bottom green of the box frame portion. and the rake-shaped seedling holders are integrally attached to the box frame portion in parallel at intervals of one seedling so as to allow the passage of the nails. This configuration provides the following effects. In other words, the seedling stand is composed of a box frame that accommodates the mat-like seedlings and a rake-like seedling trap that moves integrally with the box frame. Since the lower end of the matted seedlings is received by a rake-shaped seedling holder that does not move, the above-mentioned problem of the lower end of the matted seedlings being deformed and damaged due to sliding resistance is avoided, and the seedlings are separated one by one. This is convenient for improving the shielding performance by making seedlings of the same size, etc., and the rake-shaped seedling holder is convenient for improving shielding performance by making seedlings of the same size. This is advantageous in terms of making the entire device more compact. As a result, the synergistic effect of these advantages has led to the creation of a seedling seedling attachment device that can be used extremely conveniently as a whole. Embodiments of the present invention will be described below based on the drawings.

It is equipped with a pair of left and right propulsion wheels 4, 4, a front float 5 provided at a location corresponding to the lower part of the front engine 1, and a pair of left and right rear floats 6, 6 provided at a location equivalent to the lower part of the rear seedling tank attaching device 2. ing.

Then, the machine moves while supporting the machine body by working together with the front and rear floats 5, 6, which move smoothly over the field, and the left and right propulsion wheels 4, 4, which are in contact with the hard ground. It is designed to shield the seedlings. The pair of left and right rear floats 6, 6 have their rear ends supported on the horizontal shaft 7, and
Its front end can be folded into two and is supported by the fuselage via link mechanisms 8, 8, and is configured to be able to swing up and down with its rear end as a fulcrum.

Further, as shown in FIG. 4, the machine shaft 7 is supported by swing arms 10a, 10a which are capable of vertically swinging around the machine shaft center, and the arms 10a, 10a are operated to swing vertically. , is supported by a movable lever 10 that can be locked and held in the guide frame 9 by swinging left and right. And the lever 1

The structure is configured so that the mounting depth can be changed by this. In the figure, reference numerals 11 and 11 indicate leveling plates for leveling the tracks of the wheels 4, 4 attached to the machine shaft 7. The device 2 for attaching seedlings will be described with reference to FIGS. 1 to 3. It can be horizontally reciprocated with a constant stroke, and can hold a pair of left and right mat-shaped seedlings W in a head-slanted posture. The seedling resting table 12 is in a backward oblique position, and the seedling resting table 12 is at a fixed position in the lateral direction.
A pair of left and right Tachibana claws 13, 13 are provided which circulate up and down in synchronization with the movement of the mat-shaped seedlings W,
Seedlings W are placed one by one using the tank claws 13, 13 along the lower end row that protrudes below the lower green end of the seedling stand W.
', W' are taken out and shielded.

The seedling stand 12 includes a box frame portion 12A that accommodates mat-like seedlings W and is moved left and right, an end surface S of the lower end of the mat-like seedlings W that protrudes downward from the lower end green of the box frame portion 12A, and The lower end bottom surface T is composed of a rake-shaped seedling receiver 14 that receives the seedlings at intervals of one plant while allowing the passage of the tank claw 13, and the rake-shaped seedling receiver 14.
