Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice transplanter that is equipped with a spare seedling stand in order to increase the amount of seedlings that can be loaded onto the machine at one time.

When installing a spare seedling stand, it is often placed on the upper part of the aircraft, such as on the bonnet, in order to stabilize the balance of the aircraft in the longitudinal and lateral directions, and to take space into account.

For this reason, the main seedling loading platform and the spare seedling loading platform are likely to be arranged at appropriate intervals in the direction of movement of the aircraft. It becomes necessary for the operator to move close to the spare seedling table which is located apart from the table to replenish the seedlings, which is disadvantageous as it requires a great deal of labor and time.

In order to eliminate such inconvenience in supplying seedlings, conventionally, the spare seedling platform is mounted on the machine body in a manner that it can be freely moved in the distance direction with respect to the main seedling platform via a four-speed link mechanism, and For example, the operating tool provided on the preliminary seedling platform is provided with an operating lever for unlocking a locking mechanism constructed between the four-speed link mechanism and the machine body, as disclosed in Japanese Utility Model Application Publication No. 51-37515. In this case, when replenishing the main seedling table with spare seedlings, it is possible to move the spare seedling table close to the white side of the main seedling table while remaining in the operator's position. As mentioned above, there is no need for the operator to move to the white side of the spare seedling holder, which is located at a distance from the main seedling table, to replenish the spare seedlings, making it easier to carry out this work. On the other hand, it is possible to do this by unlocking the locking mechanism, which is ancillary work for supplying spare seedlings, moving the spare seedling platform closer to the white side of the main seedling platform, and moving the preliminary seedling platform after replenishment to the main seedling platform. If you need a complicated operation to move the seedling stand away from the seedling stand, and move the spare seedling stand close to the white side of the main seedling stand, move the spare seedling stand that contains the entire weight of the spare seedlings. Therefore, there is an inconvenience that this moving operation requires a lot of effort.

The present invention is an attempt to solve the above-mentioned disadvantages, and the present invention is aimed at solving the above-mentioned inconvenience. The structure is configured such that the seedling is biased to move away from the main seedling holder, and when the seedling is placed, the seedling is moved close to the main seedling holder against the bias due to gravity; The device is characterized by a restraining device that prevents the movement of the preliminary seedling rack to the main seedling rack side when placing the seedlings, which can be released at will. When replenishing
With the extremely simple operation of releasing the restraining device, the spare seedling stand on which the seedlings are placed can be moved away from the main seedling stand by gravity due to the total weight of the spare seedling stand, including the weight of the seedlings. It is possible to move the main seedling holder close to the white side against the urging force, and when the seedling replenishment work is completed, the empty spare seedling holder is automatically returned in the direction away from the main seedling holder by the aforementioned urging force. It can be moved.

Therefore, when replenishing the main seedling holder with seedlings, the present invention not only allows the seedling replenishment work to be carried out easily while keeping the auxiliary seedling holder close to the white side of the main seedling holder, but also enables the seedling replenishment work to be carried out easily. Moving the spare seedling stand for replenishing seedlings can now be done quickly and easily with less effort.

In addition, if the restraint release device of the restraint device is installed near the control section of the aircraft, the restraint release operation of the restraint device can be performed while remaining in the control section, and a reserve for supplying spare seedlings can be used. There is an advantage that the movement operation of the seedling platform can be performed more quickly and easily.

Embodiments of the present invention will be described in detail below based on the drawings.

In Fig. 1, a soil leveling float 6 is placed between a pair of left and right running wheels 5, 5 to level the muddy surface where seedlings are to be planted, so that it can swing vertically relative to the machine body, and in front of the machine body. The section is equipped with an engine E and a driving transmission M1, and
At the rear of the machine, there is a main seedling stand 1 with a tilted back position that can move back and forth in the left and right directions. For seedling planting, a mechanism for reciprocating the reciprocating movement of the claw 7 is installed, and for this seedling planting, a mechanism for controlling the reciprocating circulation of the claw 7 is provided. The rice transplanter shown in Fig. 1 is a rice transplanter in which a control bundle 9 is extended from the mission M2 to the rear and upper part of the machine, and a support frame 1 which also serves as a transmission case connects the traveling mission M1 and the planting part M2.
0 and the above-mentioned planting are placed on the mission M2 via the rollers 11 on the side of the preliminary seedling loading table 2 in a state where the preliminary seedling loading table 2 is movable in the distance direction with respect to the main seedling loading table 1. A guide rail 12.12 having a U-shaped cross section is installed in an inclined state at the bottom of the main seedling platform 1 side via the support member 13, and both guide rails 12.12
Among the reinforcing members 14 connecting the
6, the preliminary seedling rest 2 is biased to move away from the main seedling rest 1 when no seedlings are placed thereon, and when seedlings are placed on it, the preliminary seedling rest 2 is biased by gravity to move away from the main seedling rest 1. 1 spring 1
It is configured to move close to the main seedling mounting stand 1 side against the elastic urging force of 6.

In addition, one of the guide rails 1212 has a notch 12a formed in the middle part of the guide rail 12, which protrudes into the wheel movement path, so that the preliminary seedling stand 2 can be used when placing the seedlings. A first state that prevents movement toward the main seedling rest 1 side and movement of the spare seedling rest 2 away from the main seedling rest 1 when not placed, and a second state that swings downward and retires. A restraint device 3 is provided, which includes a switchable restraint arm 3A and a second spring 3B that elastically biases the restraint arm 3A to the first state. A restraint release tool 4 is provided which releases the restraint of the restraint tool 3 by forcibly switching the restraint device 3A to the second state via a wire 17.

In addition, 18 in the figure is a stopper that prevents the preliminary seedling mounting stand 2 from falling off.

Further, the preliminary seedling mounting table 2 may be configured to be movable in the distance direction with respect to the main seedling mounting table 1 via a link mechanism.

In addition, a weight is attached to the lower end of the assembled body extending from the front end of the preliminary seedling platform 2 in the direction of movement of the machine and hanging down via a pulley, etc., so that the preliminary seedling platform 2 is It is also possible to bias the seedlings to move away from the seedling table 1.
