Description

[Detailed description of the invention] The present invention relates to a transplanter for planting stem crops such as sugarcane, and aims to improve germination performance after planting by enabling fertilization and good soil covering.

In conventional equipment, the cultivated material, such as sugarcane cut to a predetermined size, is placed in a groove formed by a cultivator (furrower), and the crop is covered and compacted with soil. Because the bottom is wide, it is not only difficult to fertilize the covered crops and cover them with soil, but even when directly covering the covered crops with soil, the amount of soil covered may not be sufficient, which may affect germination performance. It is causing a decline in

The present invention solves these problems with conventional equipment by installing a deep trench cutting device, a cropping material input device, and a fertilizer applicator behind the soil cultivator, and its features include: In a transplanter that places crops in a trench while cultivating the soil and covering the soil with soil, a deep trench 35 deeper and narrower than the shallow trench 34 is formed behind the tiller 8 that forms the shallow trench 34. A furrow cutter 9 is disposed, a cropped material input device 10 that allows the cropped material 37 to be thrown into the deep trench 35, and a fertilizer applicator 11 that spreads fertilizer 38 into the deep trench 35 in which the cropped material 37 is placed. That's what I did.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a rotary tiller attached to an agricultural tractor 2 for towing through a three-point linkage mechanism 3, and a transplanter 4 is attached to the tiller 1.

The transplanter 4 is attached to a support rod 5 whose front end is pivotally supported on the cultivator 1, and the angle of the support rod 5 is freely adjustable by an angle adjustment mechanism 6. By adjusting the angle, the transplanter 4 is height adjustable.

1 to 3, the transplanter 4 includes a crop storage box 7 placed on a support rod 5, and a cultivator 8.
, a groove cutter 9 that is integrally arranged behind the tip of the soil cultivator 8 , a crop feeder 10 that is integrally placed behind the groove cutter 9 , and a crop feeder 10 that can be attached and detached from the rear of the feeder 10 . It has a fertilizer applicator 11 that can be freely attached, a suppression wheel 12 that also serves as a power output shaft of the fertilizer applicator 11, and a soil covering device 13.

The support rod 5 connects the rear portions of a pair of left and right front and rear rods 5a with a horizontal connecting rod 5b, and a pair of left and right gauge wheels 14 whose height is freely adjustable is provided at each rear end of the front and rear rods 5a. One of the front and rear rods 5a has an extension rod 5c tilted rearward and downward, and this extension rod 5c is provided with a seat 15 for a person putting in crops, and the horizontal connecting rod 5b
A support 16 for the soil cultivator 8 is fixed in the middle of the .

The soil cultivator 8 has approximately the same shape as a conventional one, and forms grooves that are the same in shape or shallower than those formed by a conventional transplanter. Rear cover 17 of tiller 1
is placed on this cultivator 8.

The crop feeder 10 is formed of a connecting plate 20 fixed to the tiller 8 and a symmetrical wall plate 21 welded to the connecting plate 20, and the part protruding downward from the lower end of the tiller 8 is a deep groove forming part. 22, the upper part of which is a shoot part 23 that widens upward, and the front end of the deep groove forming part 22 is provided with a groove cutter 9 that is triangular in plan view.
is provided, is integrated with the soil cultivator 8 and the charger 10, and cuts a narrow deep groove below the soil culture machine 8. The deep groove forming part 22 has its front end closed by the groove cutter 9 or the connecting plate 20, but its lower surface and rear end are open, and the shape of the deep groove formed by the groove cutter 9 can be maintained. The person seated on the seat 15 puts the crops taken out from the storage box 7 into the chute section 23.
When the crop is placed in the deep groove forming section 22, the crop is placed in the deep groove.

The fertilizer applicator 11 has a feeding section 25 at the bottom of the hopper 24 that can freely adjust the amount of fertilizer fed out, and is provided with a chute 26 extending from the feeding section 25 to inside or behind the deep groove forming section 22. One end of a transmission case 28 and an arm 29 are rotatably supported on the feed roll shaft 27 of 25, and the suppression ring 12 supported on the other end of the transmission case 28 and arm 29 rolls on the ground. Accordingly, the feed roll shaft 27 is driven via the transmission case 28.

The suppression wheel 12 is a tire wheel wider than the deep groove, and suppresses the fertilizer spread in the deep groove. The soil covering device 13 has a pair of soil covering disks 30 on the left and right, and covers the crops and fertilizer with soil so as to fill a shallow groove.

Next, the transplanting operation using the transplanting machine of the present invention will be explained based on FIG. 4.

After tilling with the rotary tiller 1, the soil is cultivated with a soil cultivator 8 to form ridges 33 and shallow grooves 34. The center of this shallow groove 34 is cut with a groove cutter 9, and a deep groove 35 which is deeper and narrower than the shallow groove 34 is formed at the bottom of the shallow groove 34, as shown in FIG. 4B. The soil 36 excavated by forming the deep groove 35 is discharged to the bottom of the shallow grooves 34 on the left and right sides of the deep groove 35.

When the worker throws the cropped material 37 into the chute part 23 of the feeder 10, the cropped material 37 is stored in the deep groove 35, and the fertilizer 38 is sprayed into the deep groove 35 from the subsequent fertilizer applicator 11 (fourth (See Figures C and D). The fertilizer 38 is sprayed in an amount necessary for the growth of the cropped material 37, and the pressure wheel 12 rolls over the fertilizer to suppress it.
(See Figure 4, E).

After fertilization, the soil covering device 13 breaks down the ridges 33 and spreads the fertilizer 38.
At the same time, the soil 36 excavated from the deep trench 35 is also covered with soil, and the cropped material 37 is covered with sufficient soil (see FIG. 4).

As shown in FIG. 4 D, the fertilizer 38 is placed in the deep groove 35.
Since the fertilizer is spread within the area, the required amount of fertilizer can be supplied to the optimum position for the cropped material 37, and the fertilizer is not spread to unnecessary positions, resulting in good fertilization performance.

In addition, as shown in FIG.
8 is scattered and covered with soil, so compared to the conventional method of placing the cropped material 37 on the bottom of the shallow trench 34 and covering it with soil, the amount of soil directly above is covered. Moreover, the soil 36 excavated from the deep trench 35
Since it is also used for covering soil, a sufficient amount of soil can be obtained.

In the present invention, the cropped material 37 is manually charged into the feeder 10, but like the fertilizer applicator 11, it has a hopper, a feeding part, a feeding part drive mechanism, and a feeding chute. An automatic crop loading device may be provided, and a shallow groove 34 may be provided at the rear of the earthen covering vessel 13 instead of or in combination with the suppression wheel 12.
It is also possible to equip a suppression ring that is approximately the same width as the one. Further, although the transplanter 4 is attached to the rotary tiller 1 to carry out transplanting work at the same time as tilling, it may also be attached independently to the tractor 2 and carry out the transplanting work after the completion of only tilling the field. .

According to the present invention described in detail above, the groove cutter 9, the crop feeder 10, and the fertilizer applicator 11 are provided behind the tiller 8, and the shallow groove 34 formed by the tiller 8 is deepened and A narrow deep groove 35 is formed, and this deep groove 3
Since the cropped material 37 and the fertilizer 38 are stored in the container 5, optimal fertilization and good soil covering can be achieved for the cropped material 37, and the soil 36 excavated from the deep trench 35 can also be used for covering the cropped material 37. This makes it possible to obtain a sufficient amount of soil and improve germination performance after planting.Moreover, it is possible to perform cultivation soil, deep furrow formation, planting of cover crops, fertilization, and soil covering at the same time, which improves the efficiency of transplanting work. It becomes possible to improve.
