DETAILED DESCRIPTION OF THE INVENTION The present invention provides a sensor float for automatically raising and lowering the vehicle 1
)) 11 J↓t 114: fl ahead of! :+
：The front end of the machine is installed in a state where it can swing up and down, and a rice planting device is installed behind the n'1# own axle so that it can be raised above the ground as the rear of the machine is lifted around the Jti axis. This article relates to a sensor float mounting structure for encouraging plant emergence.

The walking-type El planting machine detects the level change of the hard ground using a sensor float, and based on this detects the change in the level of the hard ground, raises and lowers the wheels (with respect to the whole body), and keeps the height of the machine body with respect to the planting mud surface almost constant, that is, i'' It is possible to maintain the level of the device with 44ifi on the planting mud surface almost constant to make the planting depth constant, and by providing the front end of the sensor float (till) ahead of the wheels. , when turning on a headland, the sensor float approaches the aircraft as the rear part of the aircraft is lifted by the handle, and the control mechanism stops (
1 is activated, the J11 wheel is automatically driven down to the aircraft, lifting the aircraft and the h°1 planting device, making it easier to lift the aircraft when turning, and also increasing the sensor float movement. The pivot point for the purpose is located behind the axle,
Considering the lifting of the rear part of the aircraft during a turn, the sensor float Fr1i end has a large anti-aircraft lift Flf, but at the same time the 8v body is kept as low as possible. This makes it easier to perform rotational work.

However, conventionally, the grandson of the sensor float J11. ass

In other words, by connecting the sensor float grounding part to the rear pivot point of J1111 by means of a non-contact connecting part, and by positioning the sensor float grounding part forward, the fuselage ( The effect of the sensor float that accompanies the lifting of the lower part allows the sensor to be easily rotated.
Float grounding +? ; The length after T is reduced to a large width, and the mud pushing by the steering J・' of planting II"f, which is carried out to lift the aircraft (, 2 and 3, J1H can be reduced by 1) In addition to being able to easily correct the planting direction, it is also possible to effectively avoid pushing the already planted 1 〒 1 due to mudflow, and because it is possible to use a sensor float lightly, it is possible to easily adjust the planting direction in the field.

Position the front end of the sensor claw (+4) ahead of the wheels (9), and connect it to the front end of the fuselage frame (1) via the bent link (15j) to prevent the sensor float (14) from touching the ground. The rear end of the section (14a) is positioned forward of the axle (P+), and is directed toward the X branch (3y) rearward of the axle (Pl) through the support rod (32) that does not touch the ground. It is connected so that it can freely swing up and down around the axis (P2).

The structure is such that the position is maintained within a certain range of πC, and the planting depth is made constant.

The planted clutch lever shown in Fig. 1 (2:', 1i) Although not shown, there is a stop part in the lever guide that allows automatic wheel elevation control even when the right white clutch is disengaged and operated. Sensor flow 1- (14) can be achieved by lifting the rear part of the aircraft with the handle (7) while turning on the headland with only the 1st gear cut off.
