Abstract

PURPOSE:To automate the operations of loading seedling stocks in a seedling box by inclining the seedling dividing zone so that it becomes higher toward the exit of the seedling and by setting the inclination of the bed for stock easing to a smaller angle than that of the seedling dividing zone, thus labor is saved. CONSTITUTION:The pretreatment zone and the seedling dividing zone (B) are integrally constituted and inclined so that they can fall down backward. The seedling casing zone (C) is provided with guide rail 32 connected to the frame (D), the cart 33 moving on the rail 32 and carrying the seedling case 1 and the pusher 34 for loading the seedlings coming out of the exit zone 7 into a case in order, and inclined at an angle of beta slower than that of the seedling dividing zone B alpha. Thus, the cart 33 is smaller inclined than the seedling dividing zone B is, and the operations of seedling transfer can be optimized, as the exclusive space and the height of the machine are controlled in a permissible range.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crop seedling stock splitting machine for splitting a densely grown mother stock such as straw grass seedlings into small stocks suitable for transplantation into a field.

[0002]

2. Description of the Related Art For example, as a stock dividing machine for strawberries, as shown in Japanese Utility Model Publication No. 1-32820, a pair of endless rotation bands with needles are arranged so that the ends of their rotation loci overlap each other. It is known that the mother stock introduced from the upper part is forcibly divided by the expansion operation of the endless rotation band needle in the lower wheel body by arranging and driving the same.

[0003]

According to this, the work of separating the mother stock into small stocks can be mechanized. However, the strawberries that have been divided into stocks are once packed in a storage box in an aligned state, and the storage box full of small strawberries will be carried and transferred to the seedling mounting table of the straw transplanter.
The step of filling the small boxes into the storage boxes is done manually, and there is room for improvement from the viewpoint of reducing the labor burden. It is an object of the present invention to provide a planting machine for splitting seedlings of a crop, which can mechanize the step of packing small plants into a storage box and further reduce labor.

[0004]

In order to achieve the above-mentioned object, the present invention provides a carrier device for sandwiching and transferring a mother plant of a crop seedling between a pair of endless rotary bands arranged opposite to each other, and A stock splitting unit equipped with a splitting device that acts on the roots of the mother plants transferred by the carrier to forcibly loosen and disperse the roots, and the small plants discharged from the discharge unit at the end of the carrier are sequentially placed in a seedling storage box. A seedling storage box provided with a boxing section equipped with an extruding device for stuffing and transferring, the stock splitting section being arranged in a slanted state such that it is higher toward the upper side in the discharging direction of small caps, and in the boxing section below the discharging section. The placing table for placing is placed in a slanted manner so that it becomes higher as it moves closer to the small-capsule packing direction.
In addition, it is characterized in that the inclination angle of the mounting table is set to be less than the inclination angle of the stock dividing section.

[0005]

According to the above characteristic structure, first, in the stock splitting unit, the mother stock sent from the supply unit is split into small stocks by the splitting device while being transported by the transport device, and then the small stocks are discharged from the discharging unit. In the box packing section, the small caps coming out from the discharging section of the stock sorting machine can be packed into the seedling storage box by the pushing device. This allows mechanization of the steps from stock splitting of mother stocks to box packing. By arranging the stock splitting section in an inclined manner, gravity acts on both the culm direction of the plant seedlings and the direction facing the culm, so that either the transport direction of the plant seedlings or the direction opposing the transport direction is The urging force acts in the direction as well, and the effect of suppressing the disturbance of the conveyance occurs, which can be expected to have a favorable effect. Further, the installation space can be made smaller than that of the horizontally arranged one, and the stock seedling supply section can be set at a height position suitable for the operation of feeding the stock seedlings by an operator in a standing posture. Then, when installing a seedling storage box mounting table that is placed below the small stock discharge section of the stock splitting section, if this stand is placed in a horizontal position, the occupied space becomes large and the angle difference with the stock splitting machine in the inclined layout is increased. Due to the difficulty of handing over small caplets, it is easy to obtain a good state of handing small caplets if tilted like the stock splitting machine, but the height of the entire device becomes too high, and the subsequent transfer of seedling storage boxes. It's hard to get started. On the other hand, in the present application, since the mounting table is installed at a gentler inclination than the stock dividing section, it is possible to improve the delivery state of small caps as much as possible while keeping the exclusive space and the height of the device within the allowable range. Become. Further, in the present application, while the mother stock is transported by the transport device, the stock is split by the splitting device, so that the action of each function can be made more reliable as compared with the conventional means that has both the transport and stock split functions by the endless rotation band pair, A good stock split condition can be promoted.

[0006]

[Effects of the Invention] Therefore, due to the linked setting structure of the stock splitting section and the box packing section, a series of steps from stock splitting of mother stocks to box packing of small stocks is mechanized and the labor can be further reduced. We were able to deliver small caps as smoothly and satisfactorily as possible without inviting them and packing them in boxes. In addition, by devising the function of separating the conveying function and the dividing function, the certainty and reliability of the stock splitting action in the stock splitting machine of the type using the endless rotation band pair can be improved as compared with the conventional one, and the stock splitting efficiency can be improved. is there.
