DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transplanter for planting a fixed seedling of green onions at the bottom of a settling groove formed in a mainland.

Conventionally, cultivation of long onions is performed by planting seedlings grown for 90 to 120 days using a width of 20 to 30 cm and a depth of 15 to 2 days.
The plants are planted one by one at intervals of about 2.5 to 3 cm along the shaded side wall at the bottom of the planting groove made to about 0 cm. Due to the extremely small planting interval, most of the planting work is done. It was done manually. On the other hand, recently , mechanical transplantation has also been carried out, and a set of seedlings of green onions is pinched one by one on a pair of rubber discs and rotated at a predetermined interval, and the seedlings are released at the lowest position and planted at the bottom of the groove. Has become.

[0093]

In this way, the onion fixed seedling transplantation involves planting at a very short interval on the bottom of a groove formed in a field, and it is extremely difficult to perform this manually. In particular, planting at the bottom of the groove by bending the waist is a difficult task. In the case of planting with a transplanting machine, the traveling part constituted by a crawler or a wheel is put together with the planting part in a groove to work. Since the vehicle runs on a narrow groove bottom, stability to the left and right sides is deteriorated, and therefore, auxiliary wheels protruding to the left and right of the aircraft are required.
Furthermore, since the entire body travels in the groove, it takes a lot of labor and time, such as lifting the entire body by manual labor at the end of the groove at the end of the groove when moving to the next groove, resulting in a decrease in efficiency. There is also a structure in which these planting mechanisms are configured to dig a planting groove at the bottom of the groove with a groover attached to the machine body and to plant the groove therein, but in general, the groove bottom is hard and a large groove for the groover is provided. Requires propulsion.

[0004] Further, as a labor-saving transplantation method of a fixed onion seedling, as disclosed in Japanese Patent Application No. 2-99763, the present applicant sowed three to five onion seeds in a paper tube collecting pot. 9
After raising the seedlings for about 0 to 120 days, the potted seedlings are placed on the bottom of the groove formed in the main field at an interval obtained by multiplying the seeding number by about 3 cm, and transplanted by covering the soil. The onion seedlings in each pot are naturally kept in a serial arrangement at intervals of about 3 cm by burying and burying the soil several times according to the growth, and extremely good onions are harvested during harvesting. Developed what you can get. However, a transplanter for planting the paper tube collective potted seedlings in the grooved bottom has not yet been announced.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies on the above-described mechanical transplantation of the fixed onion seedlings into the groove bottom, and as a result, the transmission of the engine provided on the transplanter machine frame has been changed by a transmission (transmission). ), And a pair of left and right running wheels that receive and roll through are set to a wheel interval that allows the vehicle to run across the planting groove formed in the field, and are connected to the machine frame so as to be able to move up and down. A lifting device that moves the machine frame up and down with respect to the traveling wheels is interposed between the machine frame and the machine frame. At the time of planting, the front portion that contacts and rolls on the side wall of the constant planting groove is provided. On the side of the traveling guide wheel, planting device, crushing wheel and constant groove
Drop the rear traveling guide wheel or the soil cultivator that makes contact with the wall into the planting groove formed in this field, run the traveling wheel across the planting groove, and plant it.At the end of the planting groove, the front traveling guide wheel Then, the planting device, the pressure-reducing wheel and the rear traveling guide wheel, or the soil cultivator are pulled up from the groove, so that the work can be easily re-routed to the next groove.

That is, from the drive pulley at the output shaft end of the transmission unit fixed to the machine frame that receives rotation from the drive engine provided at the front of the transplanter machine frame, it is connected to the shaft end of the traveling wheel rotating shaft interlocked with a chain or the like. The right and left wheels are fitted to form a traveling wheel. At this time, it is assumed that the vehicle can travel across the fixed planting groove width formed between the left and right wheels in the main field. , Or the transmission output shaft should be this length.
When lifting the machine frame with respect to the traveling wheels, it is preferable to lengthen the transmission output shaft. An elevating mechanism, for example, a hydraulic cylinder fixed to the machine frame is provided below the transmission section, a bracket is fixed to the end of the cylinder, and the other end of the bracket is fixed to a mounting section covering the output shaft.

On the other hand, a front running guide is provided at a substantially central portion of the fuselage.
The wheel , the cultivator, the planting device, the crushing wheel, the rear running guide wheel and the like are provided on the machine frame in this order, and these are all shaped to enable work in the groove corresponding to the fixed planting groove, as described above. When the elevating mechanism, for example, a hydraulic cylinder is operated to lift the machine body frame upward, the traveling gear provided on the machine frame is raised.
The id wheel , the cultivator, the planting device, the crushing wheel, and the rear running guide wheel are to be pulled up from the ditch while the running wheels are stopped on the field surface.

[0008]

According to the present invention, potato seedlings, such as potato seedlings, which are successively sent, are separated and held one by one by a planting holder in a settling groove formed in this field. At the time of planting at the bottom of the groove, the left and right running wheels wider than the groove width always run on the main field plane on both sides of the groove to perform stable running of the aircraft, and also as a hydraulic cylinder fixed to the transmission lower machine frame Such an elevating mechanism has its tip connected to a cover of a transmission output shaft that is linked with a traveling wheel rotating shaft and a chain or the like, and pushes up the entire machine frame starting from traveling wheels fixed to the ground. Also, when the rear running guide wheel provided behind the crushing wheel is attached to the crushing wheel support rod via a link mechanism, it moves horizontally in accordance with the vertical movement of the crushing wheel, and always stays horizontal with respect to the traveling direction. The rotation is performed while maintaining.
