Description

[Detailed Description of the Invention] The present invention relates to an improvement of an apron adjustment device for a riding rice transplanter, which adjusts the amount of scraping by the planter by adjusting the apron attached to the outlet of the seedling stand.

Conventionally, in this type of riding rice transplanter, when adjusting the mounting position of the apron, the operator would step down from the driver's seat onto the rice field, loosen the adjustment bolt, adjust the apron forward or backward, and then tighten the adjustment bolt. It is extremely troublesome for people to get on and off the plant and to adjust the apron's advance and retreat, and it also reduces the efficiency of planting work.
Furthermore, when tightening multiple bolts, the amount of adjustment of the apron becomes uneven between the left and right sides.

Another known method of adjusting the scraping amount is to adjust the rotation trajectory of the planter, but since the planter is located at the highest part of the machine, it is difficult for the driver to get off the machine or for an assistant to enter the field. I had to adjust it, but it was still a pain.

The purpose of this invention is to improve the above-mentioned drawbacks.
A riding rice transplanter is equipped with a planting device in which a seedling platform is tilted forward so that it can be raised and lowered by a top link and a lower link, and an apron facing a planter of the planting device is installed in a manner that can be moved back and forth. In addition to providing a support portion that guides and supports the apron so that it can advance and retreat across multiple locations in the left and right lateral directions of the machine frame of the device,
An apron movable mechanism consisting of a plurality of parallel links for adjusting the apron forward and backward in parallel along the machine frame of the planting device is arranged on the back of the seedling platform, and an upper end is provided on one side of the apron movable mechanism. The present invention is characterized in that an operating lever is attached which is directed toward the driver's seat on the machine body and which is operated laterally along the lower surface of the seedling stand.

The embodiments shown in the drawings will be explained below.
Reference numeral 1 denotes a wheel-type tractor body, which is equipped with an engine 2 at the front, a driver section 3 at the middle, and a driver's seat 4 at the rear. The planting device 7 is attached to the lower links 6, 6 so that it can be raised and lowered, and the machine 1
It is raised and lowered by a hydraulic cylinder attached to the

The planting device 7 is equipped with four planters 9 at the rear of the machine frame 8, and the lower part of the outlet 10a of the seedling stand 10, which is provided at the front and is tilted forward and moves back and forth from side to side, is installed at the rear of the machine frame 8. has an apron 11 attached.

The base of an operating lever 20 is fixed to the link arm 14 at the left end.
0 is along the lower surface of the seedling platform 10 as shown in FIG. 1, and its tip is directed toward the driver's seat 4, and when the planting device 7 is raised as shown by the chain line,
Since the driver's hand is within reach, when adjusting the amount of pine seedlings to be scraped in the seedling stand 10, the driver seated in the driver's seat 4 can reach out with one hand to one side. When the operating lever 20 located at 1 is rotated left and right, the parallel link arms 14... are interlocked by the connecting rods 16 and rotated left and right, and the link arms 14...
The diagonally horizontal elongated hole 19 at the other end pushes the pin 18 upward or downward, so the apron 1
1 moves up and down uniformly along the lower surface of the seedling stand 10, and the amount of scraping by the planters 9 is adjusted. At that time, the operation lever 20 is
Since it is located on one side of the seedling table 10 and along the lower surface thereof, it can be easily grasped by simply extending one hand backward, and it operates smoothly in the space free from obstacles on the lower surface of the seedling table 10.

In addition, 21 in the drawing indicates plates 17 at both left and right ends,
A guide plate fixed to the apron 17 prevents the apron 11 from moving laterally. In addition, 22 is an operating lever 20
Guide plate with seedling removal amount display mark 2
3 is attached, and 24 is the link arm 1 on the left end.
4 is a spring that presses the support plate 13 against the support plate 13.

Since the present invention is configured as described above, when adjusting the amount of seedlings scraped by the planter, the driver or an assistant does not have to enter the field and adjust the apron forward or backward, but the driver can adjust the amount of seedlings scraped by the planter using one hand while remaining in the driver's seat. You can easily grasp the operating lever on one side by extending it backwards, and the operating lever is operated laterally along the bottom surface of the seedling platform, so there is a top link below the seedling platform. Despite the installation of operating wires, transmission shafts, and various other devices, the amount of seedlings to be scraped can be adjusted smoothly and accurately.

Moreover, since the apron movable mechanism is constituted by a plurality of parallel links, the amount of adjustment of the apron's forward and backward movements will not be uneven on the left and right sides, and the amount of seedlings scraped by the planter can always be made uniform.

Furthermore, since the driver does not walk on the field and disturb it, it is possible to prevent the planted seedlings from falling over.
