Abstract

PURPOSE:To hardly cause trouble, such as deformation or running on of seedlings, by providing stoppers of supporting members capable of placing plural reserve seedlings therebetween in the seedling delivery direction so as to enable taking out and putting in. CONSTITUTION:When a supporting member 10 is set in a holding posture, upper reserve seedlings (W) are prevented from downwardly moving by a stopper 18. The supporting member 10 is set in a delivery tilted posture to deliver the lower reserve seedlings (W) by own weight thereof and the stopper 19 is then changed over to a nonoperating state with an operating lever 26. Thereby, the upper reserve seedlings (W) are delivered.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a holding posture that prevents the mat-like preliminary seedlings from slipping out, and a downward displacement of the end on the seedling sending side to prevent the preliminary seedlings from sliding. The present invention relates to a preliminary seedling replenishing device having a support member that can be switched between an inclined feeding position and a feeding tilted position.

[Conventional technology]

Conventionally, as a spare seedling supply device configured as described above,
There is a device such as that shown in Japanese Patent Publication No. 57-46324, and in this reference, a stopper is provided at the end of the support member on the seedling delivery side to prevent the movement of the seedling by contacting the end of the seedling. , this stopper is configured to release the blocking in conjunction with the support member being switched to an inclined position for sending out the seedlings.

[Problem to be solved by the invention]

Considering the recent rice transplanters, some of the currently developed rice transplanters are of the high-speed planting type with two planting arms per row for planting seedlings. With rice transplanters that can plant seedlings at such high speed, the consumption rate of seedlings also increases, so in order to avoid frequent seedling replenishment operations, a backup seedling replenishment device that can replenish a large amount of seedlings at one time is installed. is necessary.

However, in the device cited above, the movement of the seedling is prevented only by the stopper that contacts the end of the seedling, so for example, when the support member is set in the holding position, the support member may be tilted slightly. If the structure has a structure in which multiple seedlings are placed, the lower seedlings may be compressed and deformed over time, and similarly, the supporting member on which multiple seedlings are placed may be used to send out the seedlings. When switching to the tilted position, the upper seedlings may compress and deform the lower seedlings due to the force exerted by the swinging of the support member, or the upper side of the lower seedlings may It is also possible that some of the seedlings may be stranded on the ground.

An object of the present invention is to provide, through reasonable modification, a spare seedling supply device that is easy to handle and does not easily cause problems such as deformation of the seedlings or stranding of the seedlings even when a plurality of seedlings are placed on a support member. It is in.

[Means to solve the problem]

The features of the present invention are that, as described above, the spare seedling supply device is configured to be switchable between a holding position and a tilted sending position; A stopper is provided which forms a supporting member and is inserted and removed between a plurality of preliminary seedlings placed on the supporting member, and secondly, the stopper:
An operating mechanism is provided for switching to a non-operating state in conjunction with switching the support member to the forwarding tilted position, and its operation and effects are as follows.

[For production]

If the above feature is configured as shown in FIG. 1, for example, when the support member (10) is set in the holding position, the stopper (19) prevents the downward movement of the upper reserve seedling (W). Moreover, by maintaining the stopper (19) in the blocking state at the timing when the entire supporting member (10) is set in the forwarding inclined position as shown in FIG. This means that it is possible to prevent the preliminary seedling (W) from moving downward due to gravitational inertial force caused by the movement.

Moreover, if the above characteristics are configured as shown in FIG. 3, for example,
In conjunction with the downward switching of the end of the support member (10) on the seedling delivery side, the operating mechanism (33) operates the stopper (19).
) will be lifted.

〔Effect of the invention〕

Therefore, even when multiple seedlings are placed on the support member by modifying the arrangement of the stopper and the addition of an operating mechanism,
A spare seedling replenishing device that does not cause problems such as deformation of seedlings or riding on the seedlings and is easy to handle since the stopper is operated together with changing the posture of the support member has been constructed.
