Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a seeding plant.

[Conventional technology]

Conventionally, the following operations are required to obtain pine-shaped seedlings for use with a rice transplanter.

In other words, bed soil is supplied to a seedling box of approximately the same size as the pine-shaped seedlings, seed rice is sown, soil is covered, water is applied, and the seedling box after sowing is placed under predetermined humidity and temperature conditions. The seeds are allowed to germinate below, and then allowed to grow and become green (references not listed).

[Problem that the invention attempts to solve]

In addition, in order to automatically perform the seeding process that was conventionally done manually, we have added a seedling box supply unit that sends out the seedling boxes, a sowing unit that supplies bed soil, sowing, etc., and a seedling box supply unit that supplies the seedling boxes after sowing. It is conceivable to configure a seeding plant with a stacking device for stacking seedling boxes to save labor and increase processing capacity, but the following problems are expected to occur.

In other words, if a seeding plant is configured with three parts: the seedling box supply section, the seeding processing section, and the seedling box stacking device, the seeding processing may be interrupted due to, for example, a failure in transporting the seedling boxes in the seeding processing section. If it is necessary to do so, it is also necessary to stop the operation of the seedling box supply unit that sends seedling boxes to the seeding processing unit, and if there is a problem with the seedling box stacking device, it is necessary to stop the operation of the seedling box supply unit that feeds the seedling box to the seeding processing unit. This requires an operation to stop the operation of two parts including the seedling box supply section, and it is expected that the operation will not only be troublesome but also require quick operation.

Therefore, it is conceivable to install a sensor that detects poor transportation of seedling boxes, etc., and install a control device that works in conjunction with this sensor to stop the operation of the seeding plant, but if you try to install a sensor and a control device like this, This has the disadvantage that the structure becomes complicated, leading to high costs.

The purpose of the present invention is to configure a seeding plant by a seedling box supply section, a seeding processing section, and a seedling box stacking device, and to prevent the process from being stopped if an inconvenience occurs at the downstream side of the processing flow of the seedling boxes and the processing is stopped. The object of the present invention is to obtain a structure as simple as possible for stopping the processing at the upper part of the flow of processing at this part.

[Means for solving problems]

The features of the present invention include a seedling box supply unit that sends out seedling boxes, a sowing unit that supplies bed soil, sows seeds, and covers the seedling boxes while feeding the seedling boxes from the seedling box supply unit, and a sowing unit that performs the sowing process. The seedling box stacking device for stacking the seedling boxes from the section is configured to be a power-driven type, and the seedling box stacking device, the seeding processing section, and the seedling box supply are arranged in order from the upper side of the power supply line to the lower side of the power supply line. Forming power lead-in points for each section,
In addition, a switch for opening and closing the power supply route is provided on the power supply line on the power supply side of these power lead-in points, and its functions and effects are as follows.

[Effect]

If the features of the present invention are configured as shown in FIG. 1, for example, if a transport failure of the seedling growing box 1 occurs in the seeding processing section B and the seeding processing must be interrupted, the second switch for the seeding processing section B will be activated. Just by turning off the power supply 20, the power supply to the seeding processing section B is stopped, and at the same time, the power supply to the seedling box supply section A is stopped.

[Effect of idea]

Therefore, by using a relatively simple structure in which a switch is inserted into the power supply line, by simply stopping the operation of the processing section that has caused the problem, the upstream side of the processing flow of the seedling box will also be stopped at the same time. As a result, there is no strain on the flow of the seedling raising boxes, and since processing can be performed on the downstream side of the processing flow of the seedling raising boxes, a structure has been obtained in which processing can be completed at the downstream side where no inconvenience occurs.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Fig. 2, there is a feed conveyor 2 that transports 1 g of stacked seedling boxes, and an elevator unit 3 that lowers the 1 g of seedling boxes from the feed conveyor 2 to a working level in a suspended state. A seedling box supply section A is formed by the seedling box feeding device 4 which takes out the seedling growing boxes 1 one by one from the group 1g of seedling growing boxes from the elevator unit 3 and sends them out in the horizontal direction. A transport conveyor 5 that transports the seedling raising boxes 1 from the seedling raising boxes 1, a bed soil supply device 6 that supplies bed soil to the seedling raising boxes 1, an irrigation device 7 that sprinkles water on the bed soil, and a sowing device 8 that sows rice seeds on the bed soil. and,
Soil covering device 9 that covers the seedling raising box 1 with soil after sowing
The seeding processing section B is formed by the conveyor 5.
A lift mechanism 10 holds the seedling growing boxes 1 that are continuously fed in by a shelf in a substantially horizontal state and lifts them upward, and the seedling growing boxes 1 lifted upward by this lift mechanism 10 are stacked in a substantially horizontal state. A lateral feed mechanism 11 with a reciprocating structure for feeding to a working position;
The seedling raising box 1 sent out from the lift mechanism 10 by the horizontal feeding mechanism 11 is held in a substantially horizontal state at the level at which it was sent out, and the full width of the seedling raising box 1 is approximately equal to the stacking position in the sending direction of the seedling raising box 1. After reaching the upper part, the opening/closing shelf mechanism 12 opens on both sides to allow the seedling raising boxes 1 to fall, and the transporting cart moves the seedling raising boxes 1 from the transverse feed mechanism 11 to the stacking position and sequentially places them on the transporting cart 13. A seedling plant is constructed by providing a seedling box stacking device C consisting of a seedling box stacking device 13 and an elevator mechanism 14 for loading a transport truck which moves downward every time a seedling box 1 is stacked.

This seeding plant is configured to continuously send out seedling raising boxes 1, sowing seeds in the seedling raising boxes 1, and stacking the seedling raising boxes 1 after sowing, so that seedling raising can be carried out in a stacked manner until germination. , seedling raising boxes 1 stacked on the transport trolley 13... is the transport trolley 1
As shown in FIG. 3, the seeds are sent to the budding unit 15, where they are allowed to germinate under predetermined humidity and temperature conditions, and then transferred to the seedling growing shelf 17 for greening by the seedling box loading device 16, where they are further grown. It is becoming more and more common.

Further, each of the seedling box supply section A, seeding processing section B, and seedling box stacking device C is configured to be electrically driven, and as shown in FIG.
