Description

  In the present invention, when a seedling box is transported to arrange a large number of seedling boxes on a floor provided in a farm, or when the bottom of the seedling box arranged in a line with the floor is in close contact with the soil of the flooring The present invention relates to a seedling box transporting and sticking machine sometimes used.

  When raising seedlings using a pot seedling box (see, for example, Patent Document 1) in which a large number of pot nurseries are arranged in a grid pattern, each pot seedling room in the seedling box is sown and sown to cover the soil. After that (for example, refer to Patent Document 2), these are sequentially arranged and arranged on a floor with a netting net (for example, refer to Patent Document 3) in the house.

  This seedling box arrangement is usually performed manually, and the procedure is, for example, to arrange seedling boxes in a horizontal row from the front side, and when the arrangement is complete, the width and length are just enough to cover one row above it. By placing a plywood board with a plywood, placing it on the plywood board, bringing the seedling box into close contact with the floor and arranging the next horizontal row, and then repeating this while shifting the plywood board forward by one row The seedling boxes are lined up to the end of the floor. Also, for example, there is a procedure in which seedling boxes are arranged at a stretch from the front side of the floor to the front, and then the seedling boxes that have been arranged are brought into close contact with the floor with a plywood board.

  On the other hand, in this method, where the burden on the operator is too great, a seedling box transporter (see, for example, Patent Document 4) that transports the seedling box in the floor, or a seedling box that can perform seedling box arrangement almost automatically. A seedling box contact roller vehicle for evenly sticking the bottom of a seedling box such as an arraying machine (see, for example, Patent Document 5) or a pot seedling box arranged in line with a floor in the house to the soil of the floor Was developed under the present applicant (see Patent Document 6).

  As shown in FIG. 7, the seedling box contact roller wheel 100 allows a leading wide roller 124 to be turned by a handle 123, and an intermediate roller 122 and a trailing roller 121 having the same width are in close contact with each other in parallel. Arrange. The leading and trailing rollers 124 and 121 are formed to have a larger diameter than the intermediate roller 122 so that the step formed between the pot seedling boxes can be smoothly overcome. When the pedal 126 is stepped on the saddle 125, the intermediate roller 122 can be driven to rotate forward and backward via a transmission mechanism 127 composed of a sprocket and a chain. The seedling box contact roller wheel 100 is made to travel evenly forward and backward on the arranged pot seedling boxes, and the seedling box is pressed against the surface of the floor to be brought into close contact therewith.

  However, since separate machines are conventionally used for the work of arranging the seedling boxes and the work of bringing the seedling boxes into close contact with each other, there is a problem that it takes time and cost to prepare them separately.

In addition, since the conventional seedling box contact roller vehicle 100 is configured to run on the pot seedling box by driving the intermediate roller 122, the intermediate roller 122 does not slip on the pot seedling box. It is necessary to increase the ground contact area between the intermediate roller 122 and the pot seedling box. At this time, the smaller the diameter of the intermediate roller 122 is, the smaller the contact area of the intermediate roller 122 with the pot seedling box becomes smaller. Therefore, it is necessary to equip a large number of intermediate rollers 122, and their transmission mechanisms 127. Is also complicated. For this reason, there is a problem that the cost increases, the weight of the airframe increases, and it is difficult to carry when the floor space needs to be changed as in the case where the floor is in a bowl shape.
On the other hand, when the diameter of the intermediate roller 122 is increased, the number of the intermediate rollers 122 is decreased, but the arrangement interval of the intermediate rollers 122 is widened, and the number of rollers per unit area is decreased. There is a problem that the pot seedling box is easily damaged.

  In addition, since the leading and trailing rollers 124 and 121 are formed with a diameter larger than that of the intermediate roller 122 so that the step formed between the pot seedling boxes can be smoothly overcome, these rollers cannot be used in common. There is also a problem that the cost increases.

In order to solve the above-mentioned problem,
A floor portion for placing a plurality of seedling boxes arranged on the floor, or for placing a weight for closely attaching the seedling box to the floor;
A frame portion for supporting the floor portion;
A plurality of wide rollers that are rotatably supported on the bottom surface side of the frame portion via a shaft extending in the left-right direction, and arranged in rows in the front-rear direction at intervals;
And a pair of handle portions respectively installed on the front and rear sides of the frame portion.

According to this configuration, by placing a plurality of seedling boxes on the floor, the seedling boxes on the floor can be arranged on the floor, and the seedling boxes on the arranged seedling boxes It can be run in the front-rear direction. Thereby, the seedling box for arranging in a floor can be conveyed by light force.
In addition, by placing the weight (for example, a heavy object or a worker) on the floor, the seedling boxes arranged on the floor are run in the front-rear direction, and the floor It is easy to make the seedling box adhere uniformly to the field.
In addition, since the pair of handle portions are provided, both the operation for arranging the seedling boxes and the operation for bringing the seedling boxes into close contact with each other can be easily moved in both the front and rear directions.
As described above, both the work of arranging seedling boxes on the floor and the work of bringing the seedling boxes into close contact with each other can be performed, so that the labor and cost of the work can be reduced.

In the seedling box transport contact machine,
The said handle | steering-wheel part illustrates the aspect provided with the support part erected in the center of the left-right direction in the said frame part, and the grip part each protruded in the left-right direction outward from the upper part of this support part.

Moreover, in the seedling box transport contact machine,
The said grip part illustrates the aspect comprised so that folding or expansion-contraction was possible so that the protrusion length to the left-right direction outward could be changed.

According to this configuration, the protruding length of the grip portion can be changed as appropriate. Thereby, for example, during the operation of arranging the seedling boxes, while the handle portion at the rear in the traveling direction of the seedling box transporting and adhering machine, the protruding length of the grip portion is increased, while the handle portion at the front in the traveling direction is Shortens the protruding length of the grip portion. Thereby, the aircraft can be traveled using the handle portion at the rear in the traveling direction, and when the seedling box is taken out from the floor in the traveling direction and arranged on the floor, the front at the front in the traveling direction. The grip portion can be kept out of the way.
Further, for example, when the airframe is stored, the space occupied by the airframe can be reduced by shortening the protruding length of the grip portion with respect to the pair of handle portions.

Moreover, in the seedling box transport contact machine,
Of the plurality of wide rollers, one or more wide rollers on each of the front and rear ends are exemplified as being arranged at higher positions as they approach the end.
