Description

[Detailed Description of the Invention] In more detail, the load on the clay pressure ring of the transplanter is stabilized, the planted seedlings are not covered with soil, the seedlings are planted directly in a good posture, and the planting depth is stable. It provides:

Conventionally, towed transplanters used in upland fields use a tractor's three-point hinoki to pull the front frame of the transplanter, cut a planting groove with an opener installed on the underside of the frame, and then plant. The shaft is inserted into the groove through a device and is compressed by a subsequent compression wheel. Also, a front wheel may be installed in addition to the suppression wheel, but with this configuration, if the opener and suppression wheel are not placed close together, the bacteria may collapse after planting, or the machine may become prone to bending. As the suppression ring stepped on the ridges that had been carefully planted, most of the weight of the aircraft was placed on the suppression ring. To solve this problem, place the front aircraft as high as possible in the frame.
Measures have been taken to prevent the aircraft from lifting as much as possible by towing the 41s' and putting as much load as possible on the front, or by loading heavy objects onto the aircraft. In addition, as mentioned above, the carts on the suppression wheels are extremely large, so in the soft lill J field, the subsidence of the yaku/tori body becomes significant, and the soil that has been planted is pushed down, and the soil in the trench made with the orbuna is collapsed on both sides. There were many drawbacks, such as the soil rising up in the heap, forcing it to be strongly suppressed without returning to the groove, and the surface of Hatosho becoming curved. .

The inventors of the present invention have conducted research to eliminate the drawbacks of conventional transplanters and perform efficient planting.As a result, it has been found that the above drawbacks can be overcome by improving the convoy method of transplanters. death,
The problem was solved by interposing an intermediate wheel between the t4 ILK PM and the towing vehicle as a towing means, and creating a transplanter that towed the front of the dragon transfer machine via the intermediate vehicle 1i4Ilk.

An example of the present invention will be explained below with reference to the diagrams. Reference numeral 1 indicates a towing vehicle, and a tractor is usually used. An intermediate wheel 2 is connected to the rear of the tractor 1, and the intermediate wheel 2 has a connecting hole 5 in the front of a frame 4, and is connected to the tractor 1 at the upper and lower sides. Bracket 6 is located below the frame 4.
The level wheel 7 is a free-rotating wheel that runs in front of the area where planting is to be carried out, and is made of steel rolls or a wheel with rubber or other materials attached to it. However, preferably, the width of each roll is about 10 to 25 cm, and the roll interval is LO cm.
Use the appropriate amount.

A disc-shaped rolling coulter 8 is provided between the level wheels 7 and 7, and has a diameter substantially equal to that of the level wheel 7, and is located below it.

For this purpose, there are two pairs of brackets 6, one level wheel 7 is supported in each row, and a rolling coulter support rod 9 is inserted between the brackets 6 in each row.
It is preferable to support the rolling coulter 8 by. In this way, the space between the level wheels 7 and 7 will not be compacted, and since the rolling coulter rotates between them, the rotation will be easy, and the ridge where the planting will be done will be done with soft kneading/fibrous material. Pieces of wood, etc. will be pushed into the ground. Therefore, the opening groove by the subsequent opener is
By making it easier and compacting both sides, it has the effect of reducing the amount of mounds of soil. Further, the level wheel 7 is not limited to this, but may be replaced with a commonly used ruler wheel and may be set behind the wheels of a tractor.

A machine frame bracket l-11k is attached to one or two shafts 10 of the level wheel 7, and an elongated hole 12 is provided above the frame 4, and all suspension links 13 are attached to the elongated hole 12. The other ends of the machine frame bracket 11 and the suspension link 13 are also connected to the front side of the machine frame 14 of the transplanter 30 by means of pins 18 in a swinging manner. Also machine frame bracket 110 machine frame 1
A long hole 15 is provided at a location opposite to 4, and a pin 16 fixed to the machine frame 14 is inserted into the long hole 15 to prevent the plate from swaying laterally. Further, punch holes 17 are provided in the front end of the pair of frames 14 in the vertical direction, and the machine frame bracket 11 has a pedestal 17'f:
A planting depth adjusting rod 19 is arranged between the two to adjust the height of the machine body and fix the bracket 11 and the promoting frame 14.

On the lower side of the machine frame 14, an opener 20, a pressure wheel 21.
1 drive wheels 22 are provided in that order, and the opener 20 moves behind the area between the level wheels 7 and 7 and is not leveled, and expands toward the rear, and its expansion width is not to be transplanted. It varies widely depending on the shape of the bacterium. Further, the pressing wheel 21 has its lower side clearly inclined inward, passes through the leveling plane formed by the level wheel 7, and advances so as to press down the groove made by the opener 20 from both sides, and the driving wheel 22 freely rotates and presses the groove made by the opener 20 from both sides. proceed. Both of them are attached to both ends of one connecting rod 23 located below the machine frame 14, and a shaft 24 is loosely fitted into the center of the connecting rod 23, and the shaft 24 is loosely fitted into the machine frame 14 on both sides. There is. Therefore, the machine frame 14 has a suppression wheel 21 and a drive wheel 2.
2 are supported via the shaft 24, the load applied to one suppression ring 21 is reduced to 1/4 from the conventional 1/2. Therefore, even when loaded with hundreds of kilograms of seedlings, the load weight is reduced and subsidence is extremely low.

Furthermore, since the machine body swings around the shaft 24, even if the field is uneven, the vertical movement is only 1/2 of the unevenness.

Furthermore, in the present invention, since the shaft 10 of the intermediate wheel 2 pulls the machine frame 14 via the machine frame bracket 11, f14I
11 Since the position of 11 o is low, it is always pulled downward, and the opener 20 always penetrates the ridge to a constant depth and floats, almost unaffected by field conditions, according to the setting amount of the planting depth adjustment rod 19. Never again.

A heavy stand 25 is provided above the machine frame 14, and the seedling stand 2
5 is composed of a conveyor, and on the top surface is
Continuous paper cylinder seedlings 26 as shown in No. 30805 are loaded. The conveyor rotates a chain wheel 30 fixed to the shaft 24 via a chain wheel 29 by a chain wheel 28 fixed to the shaft 27 of the driving wheel 22, and the chain wheel 30 is connected to an intermediate shaft 31, 32, an intermediate shaft 3:3, The intermediate shaft 35 is rotated through the chains 36, 37 and 38, 39 stretched between 3 = 1 and 35, and the gear 40, 41 provided between the intermediate shafts 32 and 33. The chain wheel 43 fixed to the shaft 42 of the conveyor 25 is rotated to rotate the seedling stand 25 in the direction of the arrow. A kite roll 7I4 is provided at the feeding end of the seedling stand 25, and the continuous paper tube seedlings 26 are held between a pair of row-shaped seedling pull-out belts 45° 45 driven by the intermediate shaft 34. They are pulled out in rows.

A pair of inclined separation rolls 46 which are interlocked with the intermediate shaft 44 and rotate faster than the belt 45 are provided at the conveying end of the row-shaped separation pull-out belt 45, so that the separation rolls 46 are fed between them, and the separation between the two is carried out. Due to the speed difference, the seedlings are separated into paper tube seedlings one by one, separated and collided with the impact plate 47, and fall down the drop tube 48. The drop tube 48 is entirely curved at the bottom in the direction of movement of the machine body, and its end is opposed to a guide plate 49 fixed to the back side of the opener 20. Since this guide plate 49 has a curved surface facing in the opposite direction to the drop tube 48, the fallen paper tube seedlings land in the grooves made by the opener 20 and are planted.

The present invention is constructed as described above, and when the frame 4 is connected to the tractor 1 etc. and towed during operation, the level wheel 6 runs on the ridge, leveling the ridge, and creating a groove in the center. is unbalanced. The level wheel 6 receives the cart on the frame 4, and the load is evened out to prevent the soil from being raised by the opener.The shaft 10 pulls the machine frame 14, and the machine frame The bracket 11 is fixed at the desired position with the planting depth adjustment rod 19, so the mowing depth can be adjusted easily.
The cutter 20 is controlled by a level wheel 6 which moves horizontally to form a groove of a constant depth.

Therefore, the 6j that has fallen from the drop tube 48 is transplanted in a constant manner and will not be shallowly planted or deeply planted. In addition, since the suppression wheel 21 and the drive wheel 22 swingably support the other frame 14 via the shaft 24, unevenness in the field can be avoided. , -Since there is no vertical movement of the cover, the vertical movement of the opener 20 is reduced. Furthermore, since the suppression wheel 21 is provided with the above-mentioned level wheel 6, it moves behind the seedling with little heaving, so there is no need to cover the planted seedlings with soil as in the conventional method.

As described above, the device of the present invention has many advantages, so that the conventional inconvenience of carrying out transplantation while being lifted by a tractor is eliminated, and the tractor is simply lowered when the level wheel touches the field and can be pulled. It is easy to use and does not require any special skill. Also, after planting, both sides of the seedling are evenly crushed, which results in good rooting and smooth growth thereafter.

Although the above example shows an example in which the device of the present invention is attached to a lowering type transplanter, it is not limited to only a dropping type transplanter, but can be applied to various forced planting type transplanters. It is effective.
