Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a planting device connected to the rear of a passenger vehicle body so as to be able to rise and fall, and a group of soil leveling floats installed in parallel to the seedling planting device for detecting ground pressure. The present invention relates to a riding-type 10-planter in which the sensor float is configured as a sensor float, and the sensor float is linked to an elevation control fA groove of a seedling planting device so as to maintain the ground pressure detected by the sensor float within a set range.

In general, in-planting machines use soil leveling floats for seedling planting III.
The height of the seedling planting mechanism relative to the 18 sides can be changed by moving the nearby mounting fulcrum up and down, thereby adjusting the planting depth. Because the fulcrum is adjusted at the same time, not only is the adjustment operation cumbersome, but also the amount of adjustment may be incorrect, resulting in differences in the planting depth of the seedling planting mechanisms that are placed side by side. Ta.

In addition, the planting depth is often adjusted after driving a short distance in the field and confirming the planting depth. Move to the device. By the way, riding-type planting machines are generally equipped with a device for planting one or more rows of seedlings in order to increase efficiency.
The installation width of the soil leveling float is also wide. Therefore, the farmer who descends on the field has to move to the left, right, and rear of the seedling planting device to adjust each soil leveling float, which is not only extremely troublesome in fields with deep plowing plates, but also causes trouble after trampling the field. #1 There was a risk that it would interfere with any planting or trample over already planted seedlings.

In addition, especially regarding the sensor float, if the mounting height of the float is different from that of other soil leveling floats when adjusting the planting depth, the grounding condition of the sensor float will change and the sensing characteristics will change, making it difficult to raise and lower properly. There was a drawback that there was no control.

The present invention solves the above conventional drawbacks, allows easy and easy adjustment of planting depth, and performs good vertical control of the seedling planting device by stable ground pressure sensing regardless of the adjustment of the planting depth. This is an attempt to provide a riding type 11m device that can be used for riding, and its feature is that the mounting fulcrum near the seedling planting mechanism of all the soil leveling float groups, including the sensor float, can be controlled simultaneously in the same direction by seven operating tools. It has an adjustable height configuration.

In other words, according to the present invention, since it is only necessary to operate one of the six operating tools in one place, there is no need to move around the field, adjustment work is simple and quick, and adjustment errors for each float It is now possible to achieve the desired planting depth in all prefectures without causing any problems.

Moreover, since the sensor float is also adjusted at the same time, it is possible to stably maintain the sensor sensing characteristics and perform good lifting control of the seedling (i) 1 device α.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

By contacting the operation arm ←1 with the pin (431), the spoop/l/ (sinus) is moved laterally, the lift arm (IC11) is forcibly swung upward, and the seedling (11 (device (2)) is be done. Also,
1"11'4 When the direct-mounted f valley (2) is floated above the river surface (Tl) and the operating levers (3) are swung forward (f) from the neutral position (n), the operating arm will be pinned. (The spoop/l/f: 1 (η) can be moved to the lowering operation direction 0 at a distance from the 4th row, and 9) At this time, the sensor float (21
' ) is lowered by its own weight, but the L7 (1.
is swung in the downward direction, the spool (3G) is moved to the downward direction 0 via the fork (42), and the seedling (directly planted (2)
falls under its own weight. In addition, when the seedling planting device (2) is floating above the ground and the operating lever side is set to the neutral position Wl(n), the lever (39
) has a better holding force than the 1/'0 operating force of the automatic operation lever (41), so Subu # (3G
) is held in a neutral position (N) in contact with the arm 4, and the seedling 1i'i4 device (2) is fixed at an arbitrary height position above the ground.

(11) With the automatic lowering mechanism in the field, move the control lever 噸) forward (
f), perform rocking operation to the operating limit and set Springbow/L/
If the position is maintained by the pressing force (44), the seedling planting device (2) will descend under its own weight as described above. When the ground pressure acting on the sensor float (21') reaches a certain value, the rear fulcrum <y> of the sensor float (21') rises and the L-shaped arm 1) resists the spring (c). As a result, the inner wire (33a) is loosened, and the automatic operation lever (41) is returned to the neutral position by the restoring force of the spring (471), thereby lowering the seedling planting device (2). In other words, the seedling planting device (2) is automatically stopped when it is lowered to a certain height relative to the river surface tT). In this state, the planting operation is carried out.

When the tractor Tl) reaches a deep part of the tiller (G) and sinks during the above-mentioned planting operation, the sensor float (21') is pushed into the river surface (T) and the ground pressure increases. However, when this ground pressure becomes larger than the set value and the rear fulcrum (P'') is pushed up and the K-shaped arm (31) is swung against the spring 132, the inner wire (33
The automatic operation lever is attached to the spring (
471 presses the spool (3e rises, and sensor flow as the seedling planting device (2) rises) (21')
When the ground pressure decreases to the set value, the automatic operating lever (41) returns to the neutral position due to the balance of the spring (c), +47), and the raising of the seedling planting device (2) is stopped.

Also, when the tractor +1) climbs onto a shallow part of the plowing platform 0) during the planting operation, the L-shaped arm (21') swings due to the weight of the sensor float (21'), and the inner wire (33ml) is removed. Pull and swing the automatic operation lever +41) in the downward direction. When the ground pressure of the sensor flow (21') rises to the set value due to the descent of the seedling planting device 1λ (2), the automatic t'Δ cropping lever +41) is returned to the neutral position and the descent control is stopped. .

If there is a local unevenness on the ET1 surface (T) during the planting operation, the front part of the sensor float (21') will follow this unevenness, but the sensor float (91') will not be able to reach the rear support point (P). Elevation control is not performed simply by moving i, 1 around sensor flow) (21'), and the average ground pressure for sensor flow (21') deviates from the set reference value and acts on the rear fulcrum (P') upward or downward. The required lifting and lowering control is performed only when the force increases significantly.
