Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a seedling processing section for supplying, sowing, and covering soil along a feeding direction of a conveyor, and a seedling box at a position above the seeding processing section in the feeding direction of the conveyor. The present invention relates to an improvement in a sowing plant in which a supply unit and a tray supply unit that supplies a pot tray to a seedling box sent by a conveyor are arranged.

[0002]

2. Description of the Related Art Conventionally, there is a sowing plant as described in Japanese Patent Application Laid-Open No. Hei 6-225543 as a seeding plant. In this conventional example, a pot sheet feeding device is provided at a position above a conveyor for feeding seedling raising boxes. When the seedling box sent by the conveyor reaches a predetermined position, the bottom plate of the pot feeding apparatus is opened and the lowermost one of the stacked pot sheets (corresponding to a pot tray) is dropped onto the seedling box. It is supplied in form.

[0003]

As an example of sowing seeds in a pot tray supported by a nursery box, a vegetable or flowering plant is used as an example. When seeding a vegetable or flowering plant, a resin film pot is used. This is a processing mode in which a tray is used and seeds of vegetables and flowers are sown in the openings of the pot trays. However, the pot tray made of resin film has a weak surface and an unstable shape, so that there is a problem that it is difficult to reliably supply a seedling box that is fed at a constant speed by a conveyor.

[0004] Some of the recently proposed sowing plants can be used for both sowing of rice and sowing of vegetables and flowers, but at the time of sowing of rice, it is necessary to supply a pot tray to a nursery box. However, although it is necessary to supply a pot tray to the nursery box during the sowing process of vegetables and flowers, there is no one that can perform this switch rationally, and the shape of the pot tray is unstable as described above. In view of the difficulty in handling, it is desired to be able to perform two kinds of sowing processes without difficulty.

[0005] An object of the present invention is to make it possible to switch between sowing treatment of paddy rice and sowing of vegetables and flowers, and to surely supply a pot tray to a nursery box during sowing of vegetables and flowers. Rationally.

[0006]

According to a first feature of the present invention, as described at the outset, a seeding treatment section for supplying, sowing, and covering soil along a feed direction of a conveyor is formed. In the seeding plant, a seedling box supply unit and a tray supply unit for supplying a pot tray to the seedling boxes sent by the conveyor are arranged at a position on the upper side of the seeding unit in the conveyor feeding direction. Part, seedbed supply of seedlings for rice seedlings,
Select one of a first seeding treatment mode in which soil covering is performed and a second seeding treatment mode in which floor soil is supplied to a pot tray held in a seedling box sent by a conveyor, seeding of vegetables or flowers, and soil covering are performed. When the first seeding processing mode is selected, the seedling box from the seedling box supply section is sent to the seeding section at a set speed, and when the second seeding processing mode is selected, the seedling box supply section is provided. At the timing when the seedling box is fed to the position of the pot tray supply unit, the feeding operation of the seedling box is temporarily stopped to provide a speed control means for assisting the supply of the pot tray to the seedling box. The operation and effect are as follows.

[0007] A second feature of the present invention (claim 2) is that, in claim 1, the seedling box supply section takes out the seedling boxes one by one from the stacked seedling boxes and continuously feeds the seedling boxes to the conveyor. It is constituted by a nursery box supply device for supplying, and its operation and effect are as follows.

[0008] A third feature of the present invention (claim 3) is that in claim 1, the pot tray supply section takes out the pot trays one by one from the stacked pot trays and supplies them to a seedling box on a conveyor. The operation and effects are as follows, because the apparatus is constituted by a pot tray supply device.

A fourth feature of the present invention (claim 4) is that in claim 3, when the first seeding processing mode is selected, the pot tray supply device is not operated, and the second seeding processing mode is selected. Is provided with a switching means for operating the pot tray supply device when the operation is performed.
And the effect is as follows.

A fifth feature of the present invention (claim 5) is that, in claim 3 or 4, wherein the pot tray supply device is configured so that the opening surface of the pot has a vertical wall shape and the pot trays are stacked. The operation mode is set in such a manner that the pot trays are taken out one by one from the stacked pot tray group in the horizontal orientation and taken out and supplied to the seedling raising box. It is as follows.

According to the first feature, when the first seeding mode is selected, the seedling box from the seedling box supply unit is sent to the seeding unit at the set speed, and the second seeding mode is selected. When the mode is selected, the seedling box from the seedling box supply unit is sent to the seeding processing unit via the pot supply unit, but the seedling box is sent when the seedling box reaches the position of the pot tray supply unit. Since the supply of the pot tray is assisted by temporarily stopping the supply, the supply accuracy can be improved even if the shape of the pot tray is unstable.

According to the second feature, since the seedling box is continuously supplied from the seedling box supply device to the conveyor in the seedling box supply section, the labor for the worker is reduced as compared with the case where the seedling box is supplied artificially. The above burden can be reduced.

According to the third feature, since the pot tray is supplied from the pot tray supplying device to the seedling raising box in the pot tray supplying section, the labor for the operator is reduced as compared with the case where the pot tray is supplied artificially. Burden can be reduced.

According to the fourth feature, when the first sowing process mode or the second sowing process mode is selected, the state in which the pot tray supply device is operated and the state in which the pot tray feeding device is not operated in conjunction with the selection. Is performed, the labor for the operator to perform a special switching operation is reduced.

According to the fifth feature, when the pot tray is supplied from the pot tray supply device to the nursery box,
Since the pot tray is peeled off in the horizontal direction, for example, a phenomenon in which an extra pot tray is erroneously sent out by its own weight, such as taking out a pot tray from the lower end of a stacked pot tray, occurs. It will be difficult.

[Effect of the Invention] Therefore, a sowing plant capable of switching between sowing treatment of paddy rice and sowing of vegetables and flowers and capable of reliably supplying a pot tray to a seedling raising box at the time of sowing of vegetables and flowers is provided. It was reasonably configured (Claim 1). Also, the seedling box can be easily supplied without burdening the operator (Claim 2), and the pot tray can be easily supplied without burdening the operator (Claim 3). By simply switching, the operation and stop of the pot tray supply device are automatically switched without causing erroneous operation (claim 4), and one pot tray is reliably supplied to the nursery box. (Claim 5).
