Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a paddy field transplanter (rice transplanter) or a field transplanter. More specifically, one machine is used to plow only the part corresponding to the planting ridge. The present invention relates to a transplanting machine in which seedlings are simultaneously planted in the plowing part.

Conventional technology and problems to be solved Conventional rice cultivation system (tillage-scraping-planting) of the conventional practice is all field work that cultivates and scrapes the entire field, and also uses a tiller, tractor, etc. And plowing and slaughter,
After that, planting is done by rice transplanters, and at least a machine for tilling / slaughtering and a machine for planting are required, and further, after scraping after plowing work, it is left for a few days and the mud settles down. Since the seedlings are planted waiting for, the time and labor required for the field maintenance work will be long and the cost will inevitably be high.

Therefore, in the transplanter of the present invention, a plowing action part for plowing only a field scene slightly wider than the lateral width of the planting claw of the planting rod is arranged in front of the planting rod. The above-mentioned problems are solved by mounting the plowing rotary device and arranging the plowing action part of the plowing rotary device so as to correspond to each planting rod and located on the virtual extension line of the planting strip. Is what you are trying to do.

Action Water is poured into a no-till field and the machine is run with the water infiltrated into the soil to plant seedlings. When the planting clutch lever is turned on, the plowing rotary device mounted in front of the planting rod is activated at the same time as the aircraft is running, and the plowing action section is able to cover a mud that is slightly wider than the lateral width of the planting claw of the planting rod. After plowing, seedlings are successively planted in this plowing area by the subsequent planting rod.

Example 1 is a book of a rice transplanter in which a planting section A including a seedling platform 2, a drive case 3, a planter case 3a, a planting rod 4 and a float F is detachably attached to a rear portion via an elevating link L. The machine is equipped with a front wheel 5 and a rear wheel 6, and is equipped with a fertilizer applicator B for fluidized fertilizer including a fertilizer tank 7, a fertilizer pump 8, a suction hose 9, a discharge hose 10 and the like. The outlet of the connected fertilizer application nozzle 11 faces the mud on the side of the float so that side fertilization is performed simultaneously with planting. Incidentally, the planting section A adopts an automatic hydraulic control system by float detection as in the conventional case. 12 is a tilling rotary device, and this tilling rotary device 12 is adapted to till the field scene which is slightly wider than the width of the planting claw 4a of the planting rod 4 in order to cope with side fertilization. It is located between the rear wheel 6 in front of the planting rod 4 and the float F, and is attached to the planting section A via a transmission case 13 and a stay 14.

By the way, the inclination angle of the transmission case 13 and the stay 14 (the attachment angle with respect to the planting portion A) can be changed as described later, and the plowing depth of the tilling rotary device 12 can be appropriately adjusted. There is.

And the plowing action part (plowing claw) 12 of the plowing rotary device 12
a is arranged at a predetermined interval in the width direction via a shaft 15 so as to correspond to each planting rod 4 and to be located on a virtual extension line of the planting strip. Reference numeral 16 is a gear case incorporating a speed-increasing gear mechanism (not shown), which is integrally formed with the transmission case 13.
As shown in FIG. 5, with respect to the shaft case 17 that connects the drive case 3 and the planter case 3a, the pin 20 that is elastically urged toward the shaft case 17 side through which the leaf spring 18 penetrates the gear case 16 and internally houses the shaft 19. And shaft case 17
It is mounted so that the mounting angle can be adjusted and fixed through a plurality of engaging holes 21 provided in the circumferential direction, and correspondingly, the mounting angle of the stay 14 can also be adjusted by the push bolt 14a.

Now, the plowing rotary device 12 does not directly drive from the drive case 3, but during transmission from the drive case 3 to each planter case 3a (between the planter case 3a on the rightmost side of the machine body and the drive case in the illustrated example). Is configured to obtain drive.

In order to obtain the drive of the tillage rotary device 12, the planting part A has a complicated structure in which each part is complicated, and in particular, the space around the drive case in the central part has a small space, and in combination therewith, the planting part A is directly connected to the drive case 3. It is very difficult to take out the drive, and the mechanism is complicated, but the above configuration solves the problem of taking out the drive, and moreover, the gear case 16 and the transmission case 13 are attached to the plowing rotary device 12. Since it also serves as a member, it has an extremely rational design. Reference numeral 22 is a rotary cover, and a plowing soil side plate 23 is fixed to the lower surface of the rear portion thereof in the shape of an open V in plan view so as to cover the rear of the plowing action portion 12a from the left and right sides. 24 and 24a are forced earth plates arranged on the left and right sides of the seedling planting position.
4, 24a are interlockingly connected to the link 4b of the planting rod 4 via a wire 25, and are configured to perform wide / narrow expansion / contraction operation in conjunction with seedling planting. That is, a pair of front and rear rods 25, 25a, which are located below the planter case 3a and have one end side of the forced soil side plates 24, 24a fixed to the planting portion A, are slidably supported in the machine width direction. The free ends of the forced earth plates 24, 24a are slidably fitted in the other rods 25a, 25, respectively. The rods 25, 25a are connected to a T-shaped actuating metal fitting 26, which is slidably supported by the planting portion A about the pivot pin 26a, via a pin 27 and an elongated hole 28. The link 4b of No. 4 and the T-shaped actuating metal fitting 26 are connected by a wire 29 having a return spring Q. Since the actuating metal fitting 26 swings in conjunction with the operation of the link 4b, the front and rear rods 25, 25a move to the left and right. By reciprocating in the opposite direction, the space between the pair of left and right forced earth-contacting plates 24, 24a is expanded and contracted to forcibly exert a soil-contact action on the planted seedlings. 30, 30a are outer stoppers. In the figure, R is an oil pressure interlocking clutch lever, and S is a line stop clutch.

What is shown in FIGS. 6 to 9 is a plowing rotary device 12 '.
Is arranged in front of the front wheel 5 of the machine 1, a shaft center 32 is attached to a frame 31 fixed to the front lower part of the machine 1, a counter case 33 is fixed to the shaft 32, and a chain case 34 is rotary-transmitted. The chain 35 is rotatably connected vertically, and the middle part of the entire surface of the chain case 34 and the rear end of the lifting link L are connected via a wire 36. The power is taken from the rear wheel drive shaft 37 to the power take-out case 38. And counter case via rotary drive shaft 39
Introduced to 33, rotary transmission shaft 35, each chain case
The tiller shaft 40 is driven via 34, and the tilling claw 41 is rotated. 43 is a rotary cover, 43 is a spring, and 44 is a guide roller for the wire 29. The shaft
It is also possible to rotatably support the frame 32 with respect to the frame 31 and to vertically rotate the entire tillage rotary device 12 'about the shaft 32.

In the above-mentioned configuration, the seedling planting work is carried out by putting the water in the no-till field and running the aircraft in a state where the soil has penetrated the water. As in the case of the attachment, the planting clutch lever R is operated to lower the planting portion A to the ground. Then, when the planting clutch lever R enters, the plowing rotary device 12 mounted in front of the planting rod is activated at the same time when the aircraft is running, and the plowing claw 12a is forcibly rotated, so that the plowing claw 4a is slightly wider than the lateral width of the planting claw 4a. After the mud of wide width w is plowing, the mud scattered by the plowing claws 12a is backfilled in the plowing hole by the plowing soil side plates 23, 23, and is leveled by the subsequent float F. , Seedlings 4 are used to plant seedlings in this cultivated area. At this time, since the plowing width by the plowing claws 12a is slightly wider than the lateral width of the plowing claws 4a, the planted seedlings are less likely to fall sideways laterally. The seedlings planted in the plowing traces as described above are floated because mud soil is attracted from the left and right sides by the pair of left and right forced soil siding plates 24, 24a that expand and contract in conjunction with the planting rod 4. Stable and proper planting posture is maintained without becoming seedlings or lodging seedlings. In addition, the planting of the first few plants is a part that is not tilled, but there is no problem if this is treated as waste planting.

Since the plowing claws 12a are provided in front of the planting rods 4 and on the virtual extension line 1 of the planting bar corresponding to each planting rod 4, the plowing rotary device 12 is installed in the planting rods 4 of the planting rods 4. Combined with the fact that it is placed near the front, there is almost no difference between the plowing position and the planting position.

The present invention can be used not only for planting in paddy fields but also for planting field crops in fields.

Effect of the Invention As described above, the present invention has a plowing rotary unit in which a plowing action portion for plowing only a field scene slightly wider than the lateral width of the planting nail of the planting rod is arranged in front of the planting rod. Since the device is mounted and the tilling action part of the tilling rotary device is arranged so as to correspond to each planting rod and to be located on the virtual extension line of the planting strip, one machine is used to plant seedlings. Since it is possible to perform the plowing process for the required fields at the same time as planting and before planting, it is possible to omit the conventional plowing and field maintenance work such as scraping performed before planting, and it is possible to achieve great labor saving. Moreover, since the plowing is not the entire field but only the plowing section-corresponding part, the power is not wasted and efficient transplant work can be performed.
