DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an agricultural machine
The present invention relates to a transplanting machine that successively feeds out successively collected pot body seedlings on a flat bottom plate while sliding on the ground while following irregularities on the ground surface of a field, and planting them while maintaining a continuous state.

[0002]

2. Description of the Related Art Conventionally, collective pots for transplanting seedlings, which are made by sticking a large number of rotative hexagonal or square cylinder pots with water-soluble glue, are used for raising and transplanting rice, vegetables, beets and the like. It is used for These ordinary pots are separated into individual pots at the time of transplantation, but at the time of transplantation, these individual pots are planted in a field by mechanical transplantation.

[0003] On the other hand, Japanese Patent Publication No. 55-30805 discloses a collective pot for continuous seedling transplantation in which adjacent pots are connected by a connecting piece to form a single band from one end to the other end. At the time of subsequent transplantation, it is possible to pull out the most advanced pot body seedlings by pulling them to the final end pot body seedlings, while cutting the connecting pieces from the tip pot body seedlings and planting them sequentially. Tokiko Sho 55
No. -30805 cuts a separation line of a connecting piece by sandwiching a continuous potted plant between a pair of inverted conical rotators, and Japanese Patent Publication No. 63-61866 is provided radially on a rotating disk. The transplanting rod is pulled out by rotating the pin pot body surface while pinching the tip pot body surface, and the subsequent pot body seedling is stopped by the stop plate to cut the connecting piece between the preceding pot body seedling. It is. Further, in the case of a collective pot for transplanting continuous seedlings in which adjacent pots are connected by a connecting piece, the present applicant has disclosed in Japanese Patent Application No. 4-142080 that a seedling-shaped bottom plate is used as a ground surface and a continuous seedling is formed on the upper surface of the bottom plate. Placing the collecting pots for transplantation, sliding the ground surface of the field manually, and pulling out the connecting pots sequentially connected from the outlet provided at the rear of the bottom plate, continuously connecting to the field while maintaining the connected state A transplanter for planting a collective pot for transplanting seedlings was proposed.

[0004]

As described above, in a continuous seedling transplanting collective pot in which the collective pots are connected in a single band by connecting the adjacent pots with the connecting pieces, the connecting piece is cut. An automatic transplanting mechanism has been established for the purpose of separating and transplanting individual pots separately, but the transplanting machine that pulls out and transplants while maintaining the connected state without cutting the connecting piece is the above-mentioned Japanese Patent Application No. No. 4,142,080, there is only a transplanting method in which a collective pot body for continuous seedling transplantation is placed on the upper surface of a sled-like bottom plate and the field is slid by human power. In this case, planting progresses sequentially and the collective pot on the bottom plate is small. Then the bottom of the bottom plate becomes lighter and rises. Since the planting of the pot body becomes inferior when floating, a weight for preventing floating is always provided at the rear of the bottom plate. However, since the total weight becomes heavy, extra work is required in the pulling work. For this reason, there has been a demand for a method of mounting a continuous collecting pot transplanter having a grounded sled-shaped bottom plate on an agricultural work machine.

[0005]

SUMMARY OF THE INVENTION In view of the above circumstances, the inventor of the present invention can easily follow the unevenness of the ground surface of a field by a manual operation when the ground-type continuous collective potted plant seedling transplanter glides on the field. As a result of intensive research on the mechanism that can be installed and mounted in the same manner as above, a four-bar link support rod is provided on the side frame on both sides of the ground-type continuous potted seedling transplanter, and this four-bar link support rod constitutes a four-bar link By connecting the tip link of the four-bar link to the work equipment mounting device of the work equipment, the ground-type continuous pot seedling transplanter with a sled-shaped bottom plate easily follows irregularities on the field surface of the field. It is now possible to glide.

In the grounding type continuous collective potted plant transplanting machine of the present invention, side frames are fixed on both sides of a sled-shaped bottom plate. The leading link of the four-bar link is connected and running, and both sides of the sled-shaped bottom plate serve as guides on both side walls of the groove after raising the groove to maintain straightness and follow the unevenness of the groove bottom with the four-bar link The bottom plate is sequentially grounded.

Further, in transplanting vegetables, flowers and trees, etc. on a high ridge, a guide on the lower surface of a sled-shaped bottom plate on which the transplanter slidably runs guides the side of the high ridge and keeps the straight running, in connection with the cultivator. Good planting is performed by sliding on the ground following the unevenness of the ground surface due to the four-bar links.

[0008] In the present invention, the sled-shaped bottom plate is allowed to contact the ground, and the collective pot for continuous seedling transplantation on the bottom plate can be pulled out while being connected and planted as it is. The connection between the machine and the transplanter can be used as long as it has a mechanism that can follow the unevenness of the field,
In addition to the four-bar link, follow-up is possible even with a chain connection.

Further, the grounding type continuous potted plant transplanter of the present invention is characterized in that a bottom plate having a flat grounding surface has a sled shape at the front end and a groove of a predetermined length is provided at the center of the rear end to form a pot body seedling feeding outlet. Side frames on both sides of the bottom plate, and an opener
In addition, a pot body seedling guide is provided, and the upper surface of the bottom plate is a pot body seedling placement part for continuous seedling transplantation. If necessary, a high ridge guide is provided on the lower surface of the bottom plate, and a handle for human power is provided. In addition to the above-mentioned groomer and cultivator, a self-propelled transporter for vegetables and the like can be sufficiently used as an agricultural work machine to which such transplanters are connected and mounted.

[0010]

According to the present invention, a four-joint link is constituted including a four-joint link support rod fixed to the front of both side frames of a bottom type continuous potted seedling transplanter having a sled-shaped bottom plate as a ground surface. Since the tip link of the four-bar link and the work implement mounting device of the agricultural work machine are connected, the farm work machine can follow the unevenness of the field ground surface regardless of whether the farm work machine moves up and down due to the unevenness of the farm ground surface, and the bottom plate can be grounded. It is something we are sure.
