Description

[Detailed Description of the Invention] The present invention relates to a device for placing a spare seedling mat on the body of a walking rice transplanter.

In recent walk-behind rice transplanters, in order to improve maneuverability, the seedling platform is tilted backwards along the nodle located at the rear of the machine. The spare seedling stand for tilt-type rice transplanters is installed on the machine body at the front of the seedling stand, so in order to transfer the seedlings from the seedling mat on the spare seedling stand to the seedling stand, it is necessary to Workers located behind the stand have to extend their hands long beyond the seedling stand to reach the spare seedling stand well in front of it, which makes it difficult to work, allowing them to quickly and easily perform seedling succession work in a comfortable position. I couldn't do it.

The present invention is a rice transplanter with a backward-tilting seedling stand of this type, in which a spare seedling stand located in front of the seedling stand is movable back and forth, so that during seedling succession work, the spare seedling stand can be moved to the rear, i.e. by the operator. By making it possible to approach the seedlings with light force, the seedling splicing work can be done easily and quickly in a comfortable posture.

Below, we will explain the example drawings of the 6-row rice transplanter.
In the figure, 1 is the engine 3 at the front of the mission case 2.
, shows a fuselage in which a transmission case 5 is connected to the rear via a cylindrical frame 4, and a pair of left and right arms are attached to the left and right sides of the mission case 2 so as to be movable up and down via swing arms 6.6 whose base ends are pivoted. wheels 7, 7, and a total of 6 wheels are provided at the rear of the fuselage 1 on both sides of the lower part of the transmission case 5 and at the tips of connecting members 8, 8 that protrude laterally from both left and right sides of the transmission case 5. The transmission case 5 is equipped with a swing type planting mechanism 9.
A pair of left and right control handles 10 are provided in an inclined manner rearward from the
．． On the upper surface of the fuselage 10, there is a seedling stand 11 arranged approximately parallel to this, that is, inclined rearward so that the upper end is located at the rear.
It is equipped to freely reciprocate in the left and right directions.

Furthermore, floats 12, 13, and 13 are provided at the bottom of the body 1 and on the outside of both axles 7, 7, respectively.

A spare seedling storage case 14 is provided on the top surface of the cylindrical frame 4, and a spare seedling stand 15 made of a wide round bar is provided on the top surface of the storage case 14, extending in both left and right directions of the machine body 1.
When placing a large number of spare seedling mats 16 on the spare seedling stand 15, a pair of left and right guide rails 17, 17 extending parallel to the front and back direction of the machine body 1 are horizontally installed on the upper surfaces of both left and right sides of the storage case 14. On the other hand, guide frames 1B and 18 having a downward U-shaped cross section are provided in parallel on the lower surface of the preliminary seedling stand 15, and both guide frames 18 and 18 The spare seedling stand 15 is configured to be slidably fitted onto the rails 17, 17 and movable back and forth with respect to the machine body 1.

Further, both the guide rails 17, 17 are equipped with a plurality of trochanters 19, and the rear surface of the preliminary seedling stand 15 is provided with a planar U-shaped handle 20 extending rearward, so that the preliminary seedling stand 15 and the guide rail etc. A spring 21 for pressing and biasing the spare seedling stand 15 in the rearward direction is installed between it and the machine body side, so that the spare seedling stand 15 can be moved rearward with a light force. In addition, a guide rail 17 is provided on the lower surface of one of the guide frames 18 in the preliminary seedling stand 15 at the rearward movement end of the preliminary seedling stand 15.
A stopper 23 is provided which abuts against the protrusion 22 to prevent further rearward movement.

Furthermore, both guide frames 18 and 18 in the preliminary seedling stand 15
A T-shaped lever 25 is fixed with a pin 26 at the center of the lower surface of the plate 24 mounted between them so as to be horizontally rotatable, and both guide frames 18, 18! are attached to both ends of the lever 25. ,: The lock pins 27.27 provided so as to be freely protrusive and retractable are connected so that they can be simultaneously protruded and retracted by the rotation of the lever 25. A double-ended lock pin 27.27 is always urged in the projecting direction at one end of the lever 25. A spring 28 is provided, one end of the lever 25 is connected to a grip lever 30 provided on the handle 20 via a wire 29, and the lever 25 is rotated by operating the grip lever 30. Rail 17.17 has
The pin holes 31, 31 into which both the locks 27, 27 are fitted when the preliminary seedling stand 15 is in a predetermined front position, and the preliminary seedling stand 1.
By drilling pin holes 32, 32 into which the double-ended pins 27 and 27 fit when the seedling stand 15 is moved to the rear end, the preliminary seedling stand 15 can be locked immovably at both the predetermined forward position and backward movement position. It is configured as follows.

Furthermore, it goes without saying that the spare seedling stand may be moved back and forth dynamically using hydraulic pressure or the like.

In this configuration, prior to rice transplanting, seedling mats are supplied and placed on the seedling stand 11, while a spare seedling mat 16 is placed on the preliminary seedling stand 15, and then the floats 12, 13.1
3 is grounded on the field, the machine body 1 is moved straight, and each planting mechanism 9 and seedling platform 11 are driven. They are divided into sections and planted along six rows in the field.

In this case, because the guide rail 17 that movably supports the preliminary seedling stand 15 is inclined to be lower at the front end, the height of the preliminary seedling stand 15 from the field surface is lower when it is in the forward position. In the state of rice planting work, it is possible to reduce the obstruction of the worker's forward view by the preliminary seedling stand 15, and to lower the center of gravity of the entire rice transplanter. By engaging the lock pin 27 with the bottle hole 31 in the guide rail 17, the reserve seedling stand 15 can be locked so that it cannot be moved, so even if the rice transplanter is tilted during rice planting work or when crossing a ridge, the reserve The seedling stand 15 will not move unexpectedly.

Then, there are few seedling mats left on the seedling table 11,
When transferring seedlings from the seedling mat on the preliminary seedling stand 15 onto the seedling stand 11, after disengaging the lock pin 27 from the bottle hole 31, move the preliminary seedling stand 15 onto the guide rail 1.
7, but when the preliminary seedling stand 15 is moved backward, the height from the field scene to the preliminary seedling stand 15 increases along the slope of the guide rail 17, and the height of the preliminary seedling stand 15 rises to the top of the seedling stand 11. Therefore, the operator's posture when transferring the seedling mat on the preliminary seedling stand 15 from the preliminary seedling stand 15 to the seedling loading stand 11 is easier than when moving backward while keeping the spare seedling stand horizontal. By engaging the lock pin 27 with the bottle hole 32 in the guide rail 17 at this backward movement position, the preliminary seedling stand 15 can be held in the rear position, so the operator can manually remove the preliminary seedlings. There is no need to hold the stand 15 in the rear position.

However, since the guide rail 17 that movably supports the preliminary seedling stand 15 is inclined so as to be lowered at its front end, it becomes difficult to move the preliminary seedling stand 15 rearward. A spring 21 is provided to press and bias the preliminary seedling stand 15 rearward, and since this spring 21 makes it easier to move the preliminary seedling stand 15 backward, the rearward movement of the preliminary seedling stand 15 is This prevents the movement from becoming heavy due to the inclination of the guide rail 17.

As described above, the present invention provides a rice transplanter that is equipped with a control knob and a rearward-tiling seedling platform at the rear of the machine, and a rice transplanter that extends in the longitudinal direction of the machine at a position in front of the seedling platform. A guide rail is provided with a slope so that the front end of the guide rail is lowered, and a spare seedling stand is provided on the guide rail so as to be movable in the longitudinal direction of the guide rail, and the spare seedling stand is provided with the front end of the guide rail tilted so that the front end of the guide rail is lower. A detachable locking mechanism is provided to lock the seedling stand immovably in both the rear position and the rear position, and a spring is provided to press and bias the spare seedling stand rearward. It is characterized by
While it allows for a comfortable posture for transferring seedling mats from the spare seedling stand to the seedling loading stand, it also reduces the obstruction to the forward view caused by the spare seedling stand, and also prevents the center of gravity of the rice transplanter from becoming higher due to the spare seedling stand. Moreover, the spare seedling stand can be locked so that it cannot be moved in both the front position when stored and the rear position when passing seedlings, thereby preventing the spare seedling stand from moving unexpectedly. Therefore, it is not only safe, but also eliminates the need to hold a spare seedling stand in the rear position by hand during seedling succession.

Furthermore, since the spare seedling stand can be moved rearward with a light force, there is no need to hold the spare seedling stand in the rear position by hand during the seedling transfer process, and this makes it possible to transfer the seedlings easily. This has the effect of being extremely easy and quick.
