A subsidence warning device for a reaping machine is provided by installing an alarm activated by the press switch 20 and the press switch 20 at a suitable position on the machine body.

Hereinafter, the present invention will be explained based on the embodiments shown in the figures.

Referring to FIGS. 1 and 2, reference numeral 1 denotes a reaping and binding machine which is an example of a reaping working machine, and a pair of left and right running wheels 2, 2 for moving the machine body 1 back and forth are attached to the lower end of a transmission case 3. A steering handle 4 and a machine base 5 are provided to extend rearward to the transmission case 3, and a steering handle 4 and a machine base 5 are installed on the machine base 5. The machine is equipped with an engine 6 to transmit power to a transmission device in the transmission case 5, and a reaping processing unit 7 is disposed at the front of the machine body 1 with its connecting cylinder 8 fixedly connected to the transmission case 3. The structure is such that the operator performs the reaping and tying work while following the machine body 1.

The reaping processing section 7 is configured to connect a pair of right and left sled rods 9, 9' along the direction of movement of the machine body 1 with a tie that receives power from a transmission device in the mission case 3 via a transmission device in the connecting tube 8. The transmission case 10 is fixed, and the grain culm lifting device 1 is removed from the bundled transmission case 10.
1, the cutting blade device 12, and the bundling release device 13, the power is transmitted to each of the devices 11, 12, and 13 to operate the cutting and bundling work.

The sled rods 9, 9' are connected at their rear ends by a connecting rod 14 extending along the width direction of the fuselage, and
A divider 15 for weeding is fixed to each front end.

Reference numeral 16 is a grain culm guide plate for guiding the cut grain culms to the binding device 13.

The steering handle 4 is provided with a power clutch 17 that cuts off the power transmission from the engine 6 to the transmission device in the transmission case 3, and various devices 11 of the reaping processing section 7.
A reaping clutch 18 and the like are provided to cut off the transmission of power from the transmission device in the mission case 3 to the transmission devices 12 and 13.

Next, to explain the subsidence warning system, which is the main part of the present invention, a floating mud type (for example, wide plate-shaped or float-shaped) sensing body (sensing body) board) 19,
It assumes a substantially horizontal position near the height of the lower end of the running wheel 2, and is provided in a position substantially along the direction of movement of the machine body, with its front end rising portion 19a pivotably mounted so as to be vertically movable.

In this embodiment, a spring or other appropriate urging means is used as the urging means for bringing the sensing plate 19 into contact with the ground (mud surface).

Then, by positioning the sensing plate 19 so that the longitudinal width of the sensing plate 19 includes the grounding point A of the running wheel 2 within the front and rear width of the aircraft, it is possible to accurately detect the sinking of the running wheel 2 in the mud. do it like this.

The rear end of the sensing plate 19 is formed as a switch pressing part 19b, so that when the sensing plate 19 rises above a certain level relative to the aircraft body 1, it is pushed by the switch pressing part 19b and enters the "on" state. A press switch 20 which is normally in the "off" state is provided on the lower surface of the machine base 5 (or the lower end surface of the transmission case 3),
An alarm device 21 (for example, a buzzer, a lamp, etc.) is continuously connected to the press switch 20 and installed at an appropriate position on the machine so that the operator can activate an alarm when the press switch 20 is in the "on" state.

The pressure switch 20 is mounted on a mounting plate 22 and bolts 2.
3 to the fuselage body 1 so that the fixing position in the vertical direction can be changed freely, so that the height to be pushed by the sensing plate 19 can be adjusted.

In this embodiment, the switch pressing section 19b at the rear end of the sensing plate 19 presses the pressing switch 2.
However, the present invention is not limited to such a configuration, and when the sensing plate 19 rises above a certain level with respect to the aircraft body, the pressure switch 20
Any configuration is possible as long as it can be pressed to turn on.

Further, in order to cause the power clutch 17 or the reaping clutch 18 to function as one of the alarms 21, the sensing plate 19 and the power clutch 17 or the reaping clutch 18 are interlocked and connected by a wire or the like, so that the sensing plate 19 is attached to the fuselage. On the other hand, it may be configured such that the power clutch 17 is operated to "disengage" when the relative rise exceeds a certain level.

Next, the operation of the present invention implemented as described above will be explained.

When reaping work is carried out in soft rice fields such as wet fields, the running wheels 2 run while sinking to some extent under the mud, and the sled rods 9 and 9' of the reaping processing section 7 float on top of the mud to keep the reaping processing section 7 from mud. Maintain a constant height relative to the surface (see Figure 1).

The sensing plate 19 is always in contact with the mud surface and floating mud,
Aircraft 1 according to the amount of subsidence of traveling wheels 2 with respect to the mud surface.
It moves vertically.

The amount of sinking of the running wheels 2 relative to the mud surface increases,
If the machine sinks to such a depth that it becomes impossible to run or reap if it increases further (see Figure 2), the vertical height of the pressure switch 20 will be adjusted in advance so that the sensing plate 19 is pushed by the mud surface and rises relative to the machine. By adjusting the position, the pressure switch 20 is pressed to a set height, and the pressure switch 20 is pressed to turn on, activating the alarm 21 to alert the operator. In other words, workers can be notified of subsidence that would make it impossible to drive in wet fields, and such situations can be prevented from occurring.

In this embodiment, the sensing plate 19 is pivotally attached to the connecting rod 14, but the sensing plate 19 is not limited to the above-mentioned location. Any location may be used as long as it is in contact with the ground and can be vertically displaced relative to the aircraft body 1 in accordance with the vertical displacement movement of the aircraft body 1 with respect to the ground.

As mentioned above, the present invention is, in short, capable of vertically displacing the body of the reaping machine, and
A floating mud sensing body is placed in an appropriate position on the aircraft by bringing it into contact with the ground using an appropriate energizing means, and the sensing body is activated when the sensing body rises above a certain level in response to the downward displacement of the aircraft. This is a subsidence warning system for reaping machines, which has the following effects:

Immediately before the machine becomes unable to travel or perform reaping work due to subsidence in a wet field, the sensor activates an alarm to alert the operator, thereby ultimately preventing the above-mentioned situation.

(1) The sensing body is formed wide and elastically biased toward the ground, causing it to come into contact with the mud surface and act as a floating body, which serves to float the aircraft on the mud surface and has the effect of preventing the aircraft from sinking to some extent.

(2) Since the grounding point A of the wheel is located within the width of the sensing part of the sensor in the longitudinal direction, the sinking of the wheel is detected at the grounding point A of the wheel, making it possible to accurately sense and judge the amount of wheel sinking. is possible.

(3) The tip of the sensing body is pivoted in the vertical direction and extends rearward, so it has good sliding properties, reduces left and right meandering of the aircraft, and has the effect of improving the running performance of the aircraft.

(4) Under field conditions, in fields where the tiller is shallow, the position of the pressure switch 20, where the pressing part acts, can be placed upwards to prevent the machine from sinking; It is necessary to lower the switch position so that it does not sink deeply, and the machine sinks in clayey muddy soil, so lower the switch position, and raise the switch position in sandy soil depending on the field conditions and soil properties. The position of the press switch 20 can be changed up or down, and the workable area can be sensed more widely and accurately.

(5) Since the sensing body and the switch pressing part are integrally formed, the configuration is simplified and no parts are required for the switch pressing body, and the rear end of the sensing body does not stick into the soil when the machine is moved backwards. So you can retreat smoothly.
