Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transplanter for a dedicated rice transplanter for transplanting sponge-like capsules.

[0002]

[Prior Art] Recently, in addition to the current technology of seedlings and mid-sized seedlings,
Although there is a tendency to adopt an early transplantation method using milk seedlings, various seedling raising techniques have been developed to transplant seedlings so as not to damage them, and to raise seedlings while protecting them with sponge-like capsules so that seedlings do not fall over. ing.

Therefore, when transplanting seedlings raised with these capsules, missing strains and defective strains are automatically selected,
It is necessary to develop a dedicated transplant device for transplant.

[0004]

[Problems to be Solved by the Invention] In the current rice planting, when a seedling was transplanted to a paddy field, a driver checked the transplanted state such as a missing strain or a defective strain while running the rice transplanter. Since it is quite troublesome to judge the transplantation state at the same time while performing the operation, there was a risk that many planting failures occurred in the entire paddy field.

The present invention was developed for the above reasons, and its purpose is, for example, when a seedling is transplanted to a paddy field while a rice transplanter as shown in FIG. The purpose is to develop a transplantation device that can automatically and promptly and accurately detect and confirm the planting state so as not to burden the driver.

[0006]

Therefore, as shown in FIGS. 1 to 5, the transplanting device of the present invention comprises a seedling progressive feeding mechanism A, a capsule sponge cutting mechanism B, and a capsule receiving and transplanting forking mechanism C. Seedling and capsule detection adjustment mechanism D with a sensor for smoothly linking these mechanisms,
It is composed of a dedicated seedling box mechanism E and a dedicated rice transplanter mechanism F.

As shown in FIG. 2, the seedling feeding mechanism A is characterized in that the sponge-like capsules 31 are successively slid into the sponge cutting mechanism B in the next step so that the seedling feeding motor 1 works in conjunction with the seedling feeding motor 1. Belt conveyor 2 is used.

The capsule sponge cutting mechanism B is characterized in that, as shown in FIG. 3, the sponge-like capsule 31 is sent between the cutting unit 7 and the fixed-side cutting unit 8 at the time of a, and the sponge-like capsule positioning sensor 21 and the seedlings. The presence / absence sensor 22 and the sponge-like capsule presence / absence detection sensor 23 detect the cutting position through the control unit 24.

At the time point b when the sponge capsule 31 is fed into a fixed position, after the sponge is stabbed and held by the support needle 11 which is interlocked with the solenoid 9 of the cutting unit (operating side) 7,
The sponge-like capsule 31 that is cut in the next step c and then is stabbed and held by the support needle 11 at the time points c, d, and e is cut off.

The material of the sponge-like capsule 31 is
Urethane or water-soluble plastic is used.

In the receiving and transplanting fork mechanism C, when the sponge-like capsule 31 is cut off, it is pierced and pinched by the transplanting nail (needle) 16 of the fork main body 15 which moves up and down in a loop-like or rotational locus. The sponge-like capsule 31 that was transplanted into the paddy field 33 but was pierced immediately after transplantation
At the position of the optimum planting depth, the seedling holding release lever 20 operates, and the planting pusher 18 interlocks to push the seedlings into the paddy field and after transplanting, return to a fixed position on a loop or a rotation track.

The seedling / capsule detection adjusting mechanism D detects whether or not the sponge-like capsule 31 has seedlings by the seedling presence / absence detecting sensor 22, and further, the sponge-like capsule 31.
The sponge capsule presence / absence detection sensor 23 and the sponge positioning sensor 21 that determine the cutting position of the seedling are transmitted to the seedling feeding motor 1 through the control unit 24, and the pulley transmission belt 5, the electromagnetic clutch brake 6, and the seedling feeding belt conveyor 2 are transmitted. After that, the sponge-like capsule 31 is moved and fed between the cutting units 7 and 8.

The seedling presence / absence sensor 22 is a transmissive type, and the sponge positioning sensor 21 and the sponge presence / absence detecting sensor 23 are reflective types.

In the dedicated nursery box mechanism E, the lower part of the tray 26 is partially opened so that the capsules 31 can be conveyed by the conveyor 2, and the sponge-like capsules 31 are stacked in layers, so that they are sequentially fed downward. The weight 27 is adjusted so that

The dedicated rice transplanter mechanism F is the existing rice transplanter 2
The implanting device of No. 8 can be removed to easily install the implanting device for capsules of the present invention.

[0016]

The operation of the implanting device of the present invention will be described with reference to FIGS.

First, the dedicated seedling raising box tray 26 containing the seedling raising capsules is placed on the transplantation table 29 of the dedicated rice transplanting machine 28 on which the transplanting device of the present invention is mounted to prepare for rice planting work.

Next, after the engine of the dedicated rice transplanter is started, the main switch 25 of the transplanter is turned on, and at the same time, the seedling feeding motor 1 and the electromagnetic clutch 6 in the seedling progressive feeding mechanism A,
The solenoid 9 of the cutting unit (operating side) 7 is operated, the support needle 11 is pierced into the capsule sponge 31 and is fixed, and at the same time, the sponge 31 is cut.

Further, the cut sponge capsule 31
Is returned to the position d and separated together with the operating portion of the cutting unit (operating side) 7, and at the same time, the cutting unit 8 on the fixed side is moved and retracted by the solenoid 10.

In the gap between the cutting units 7 and 8, the transplanting claw (needle) 16 of the receiving fork mechanism C which moves up and down in a loop or rotary orbital shape is inserted and stabbed and held in the sponge-like capsule 31, while being held in the paddy field 33. Ported.

The actuating solenoids 9 and 10 of the cutting units 7 and 8 may be mechanical mechanisms such as cams and cranks.

[0022]

Example According to the transplanting apparatus of the present invention, it is possible to transplant to a paddy field while automatically detecting the missing seedlings produced in the capsules in the seedling raising box as the rice transplanter runs.

[0023]

[Effect] Compared to the conventional rice transplanter, the rice transplanter of the present invention has a small number of nursery boxes because it has a small area for raising seedlings, and since it does not use soil, the nursery box is lightweight.
Laborious work such as transportation of seedling boxes and frequent supply of seedlings to rice transplanters can be reduced.

Furthermore, since various types of sensors can detect and automatically prevent the missing seedlings, it is possible to reduce the missing stock replenishing work in the paddy field.

Furthermore, since each seed pad is contained in a capsule, the seedlings can be transplanted without being damaged, and the seedlings can be prevented from falling and floating seedlings can be expected, so that stable and high yield can be expected.

Since the transplanting device of the present invention can be used by partially modifying and replacing the transplanting device of the existing rice transplanter, the equipment introduction cost of the dedicated transplanting device is considerably low and the industrial value is excellent. .
