Description

[Detailed Description of the Invention] Industrial field of application The present invention relates to an auxiliary seedling stand that can easily supply auxiliary seedlings to a seedling stand of a rice transplanter.

Conventional technology Generally, mat seedlings are placed on the seedling placing table provided on the operation operation side of the rear part of the machine body, and seedlings divided into unit plantings from the lower end of the seedling placing table are planted on the rice field. In rice transplanters, an auxiliary seedling mounting table is provided in front of the seedling mounting table to mount auxiliary seedlings to be supplied to the seedling mounting table. Conventionally, this type of auxiliary seedling mounting table is fixed to the hood that covers the engine. Many are arranged, and those that move back and forth as they are, or those that rotate around the center of the auxiliary seedling stand as a fulcrum are also known.

The problem to be solved by the present invention is that when the auxiliary seedling mounting table is fixed to the bonnet, the auxiliary seedling is located far from the operator in the operation section, so supplementary seedlings can be supplied to the seedling mounting table. Since it is difficult to place the auxiliary seedlings on the auxiliary seedling mounting table and the auxiliary seedlings are placed in the longitudinal direction with respect to the machine, it is inevitable Since the seedling stand has multiple stages and the center of gravity of the machine is high, the machine becomes unstable and the planting accuracy is impaired. Since the seedlings are placed in the front-rear direction of the machine, there is a disadvantage that the seedlings must be taken from the left and right of the machine when the seedlings are replenished, and the seedlings must be re-supplied before being replenished to the seedling stand. In addition, if the auxiliary seedling table moves, it is difficult to place the auxiliary seedlings from the operation unit, and the operation of moving the left and right auxiliary seedling tables is troublesome, and handling of the seedlings is both troublesome. There's a problem.

The present invention was devised to solve the above problems, and the left and right auxiliary seedling mounts are simultaneously rotated to the left and right sides by operating only one operating tool. , The operator in the operation section can easily replenish seedlings when replenishing seedlings, and at the time of planting work, the front-rear balance of the machine is good and the auxiliary seedling platform for rice transplanters can be used in a stable state. It is intended to be provided.

Means for Solving Problems The technical means taken by the present invention to solve the above problems is to place the mat seedlings vertically on the main seedling mounting table provided on the operation operation side of the rear part of the machine body. Then, in the rice transplanter that planted the seedlings divided into unit plantings from the lower end of the main seedling mounting table on the rice field, the left and right auxiliary to place auxiliary seedlings laterally in front of the main seedling mounting table. A seedling mounting table is provided, and the respective rotation fulcrums provided on the rear side of the auxiliary seedling mounting table are interlockingly connected to each other, and one operation fulcrum is attached to one of the rotation fulcrums, and the operation lever of the operation lever is attached. It is characterized in that the left and right auxiliary seedling mounting tables are configured to rotate in conjunction with the left and right lateral seedling supply positions where the auxiliary seedlings are in the vertical direction in the vicinity of the main seedling mounting table by a turning operation.

Effect of the Invention With the configuration of the present invention as described above, if the mat seedlings are vertically mounted on the main seedling mounting table provided on the operation and operation side, the lower end of the main seedling mounting table becomes a unit planting stock. Split seedlings can be planted on the rice field. If the auxiliary seedlings are placed laterally on the left and right auxiliary seedling mounts on both sides of the machine, only one operation tool can be operated when the seedlings on the main seedling mount are reduced. The left and right auxiliary seedling mounts are interlockingly connected to each other, and pivotally move to the left and right side seedling supply positions in close proximity to the main seedling mount, and the auxiliary is placed laterally. Since the seedlings are in the vertical direction with respect to the main seedling placing table, the worker in the operation control section should take the auxiliary seedlings from the adjacent auxiliary seedling placing table and supply it directly to the main seedling placing table for easy seeding splicing. You can Even when the auxiliary seedlings are placed on the auxiliary seedling mounting table, the auxiliary seedlings can be easily mounted from the operation position by rotating the auxiliary seedling mounting table to the left and right. When the platform is rotated back, the placed auxiliary seedlings will be laterally positioned in front of the main seedling platform, so the front-rear balance of the machine is good and planting work should be performed in a stable state. You can
