Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a riding rice transplanter in which the planting section can be automatically raised when the main gear shift lever is set in reverse.

[Conventional technology]

Conventionally, in a riding rice transplanter, a planting section that can be raised by automatically raising a hydraulic lever in conjunction with the reverse gear shift operation of the main gear shift lever is attached to the rear of a passenger car so as to be able to move up and down. During work, if you want to move the aircraft backwards and bring it close to the ridge on the headland side, when you shift the main gear shift lever to the reverse position, the planting section will automatically rise so as not to interfere with backward movement. It's getting old.

[Problem that the invention attempts to solve]

However, the above-mentioned conventional riding rice transplanter had a problem in that when reversing, the operator on the passenger car was not able to fully check the rear because the seedling stand etc. in the raised planting section obstructed the operator. .

The present invention solves this problem.

[Means for solving problems]

Therefore, in the present invention, the planting part B is connected to the rear of the passenger car A so that it can be raised and lowered by automatically raising the hydraulic lever 2 in conjunction with the reverse gear change operation of the main gear shift lever 1. In the riding rice transplanter configured as shown in FIG. It is constructed by providing a means for regulating the elevation of the planting portion to be activated.

[Effect]

Therefore, when moving the aircraft backwards, if you shift the main gear shift lever to reverse, the planting section will start to rise, but when the sensor detects that the planting section has risen from the field surface, the hydraulic lever will be raised. This will force you to return to the neutral position.

As a result, the planting section is raised a little above the rice field and then stopped, allowing the operator in the passenger car to safely drive the aircraft backwards while looking over the low planting section to the rear.

〔Example〕

Next, the embodiment shown in the drawings will be described. Figure 3 shows a side view of the passenger rice transplanter, and passenger car A is
The front panel 8 has a four-wheel shape with both front wheels 6 and both rear wheels 7.
A handle 9 is installed above, a main gear shift lever 1 is installed on the left side of the seat 10 above the rear of the fuselage, and a hydraulic lever 2 is installed on the right side. The part B is installed so as to be able to be raised and lowered by a hydraulic cylinder 12 operated by the hydraulic lever 2, and when the main shift lever 1 is placed in the reverse position 13a of the shift groove 13 and the aircraft is moved backward, the hydraulic lever 2 to the raised position and the planting part B can be automatically raised, and is constructed in the same manner as the conventional structure.

In addition, the planting section B has both floats 3 arranged in parallel.
Each planting claw 15 is arranged at the rear of the row planting case 14 installed above each of a and 3b, and a seedling retrieval plate 16 installed horizontally above each planting case 14 is provided horizontally. A reciprocating seedling platform 17 is installed obliquely with a high front and a low rear, and a sensor float 3 that can move up and down relative to the lower part of the fuselage depending on the state of ground pressure is installed in the front between both floats 3a and 3b. The sensor float 3 is used as a sensor to detect that the planting part B has risen away from the rice field.

FIG. 1 shows a circuit diagram. Magnetic switch 5
is a planting part elevation regulating means that raises the hydraulic lever 2 and moves it from the operating position to the neutral position. This magnetic switch 5, a monitor switch 18 installed on the panel 8, a switch 19 that is turned on when the main shift lever 1 is put into reverse, a regulation switch 4, and a battery 20 are connected to each other. do.

Further, the regulation switch 4 is a normally open switch, and the end piece 23a of the sensor wire 23 extending from the sensor float 3 is provided with play on the operating rod 22 that leans against the operating piece 21 that is pressed upward. Interlocking and interlocking configuration.

Therefore, during operation, when moving the aircraft backwards, the main shift lever 1 is moved to the backward position 13 of the shift groove 13.
If you put it in A, the hydraulic lever 2 will be automatically raised as before, the planting part B will rise high, and the machine will be able to back up in a safe state. If the machine is to be moved back towards the edge of the ridge to perform planting from the ground, if the monitor switch 18 is turned on, the main gear shift lever 1 will be placed in the back position and the planting part B will automatically rise. In this state, the switch 19 is turned on, and the sensor wire 23 is pulled in the direction of arrow A while the sensor float 3 at the bottom of the planting part B floats above the field surface, and the operating rod 22 is separated from the operating piece 21. The regulation switch 4 is turned on, and the electrical connection of the circuit turns on the magnetic switch 5, causing the hydraulic lever 2, which is in the raised position as shown in FIG. The returning operation to the neutral position is performed as shown by the arrow B, and the planting part B is stopped in a state where it is slightly raised above the rice field to the extent that it does not interfere with the backing. Therefore, the operator who is sitting on the seat 10 must use the seedling platform 1 in the planting section B.
7, I can see clearly behind me as shown by the arrow C, and I can safely move the aircraft backwards to the edge of the ridge.

[Effect of idea]

In this way, the present invention connects the planting part B to the rear of the passenger car A, which can be raised by automatically raising the hydraulic lever 2 in conjunction with the reverse gear shift operation of the main gear shift lever 1. In the riding rice transplanter configured as shown in FIG.
Since the planter is provided with a planting part riding restriction means that raises the planter from the operating position and returns it to the neutral position, the following effects are achieved.

This means that the planting section B can be stopped at a low position without having to rise as high as in the past. The operator in passenger car A can drive safely while fully checking the rear lower part of the vehicle by keeping the platform etc. in a low position so as not to obstruct the view.

In addition, the planting portion B can be raised moderately and accurately stopped at a low level to the extent that backward movement is not hindered, and it can be automatically and smoothly operated to prevent erroneous operation.
