Description

[Detailed Description of the Invention] This invention relates to a riding-type rice transplanter designed to improve running performance and planting performance in wet fields.

A known riding rice transplanter is one in which a planting machine is attached to a towing vehicle body equipped with an engine etc. via a link mechanism. Therefore, the overall weight of the aircraft inevitably increases, and therefore,
A large traction force of the towing vehicle body in wet fields is required.

Furthermore, conventional riding-type rice transplanters have the disadvantage that the field surface is disturbed by the drive wheels of the tractor body, making it difficult to plant seedlings in an orderly manner.

Therefore, the object of this invention is to provide a small and lightweight riding rice transplanter with excellent seedling planting performance and configured to have a large traction force.

For this reason, the following technical measures were taken.

In other words, in a riding rice transplanter in which a planting machine is attached to a towing vehicle body, a gate-shaped space is created by a transmission case installed on the towing vehicle body and a pair of left and right transmission cases extending rearward from both sides of the transmission case. The seedlings are planted between the two transmission cases, between the transmission case and the rear wheel pivotally supported on the outside thereof, and on the outside of the rear wheel. This is a riding-type rice transplanter.

The details of this invention will be explained below with reference to the embodiments shown in the drawings.

The embodiment shown in the figure shows a riding-type rice transplanter with 5 rows. 1 is a towing vehicle body, an engine 3 is mounted on a chassis 2 at the front, front wheels 4 for operation are equipped, and a transmission is mounted at the rear. A transmission case 5 having a rear wheel differential and a rear wheel differential is provided, and a transmission case 6.6 extending toward the rear of the towing vehicle body is provided on both sides of the transmission case 5. Rear wheels 9, 9 having propulsion lugs 8 pivotally supported by an axle 7 are installed on the outside of the rear end.

Furthermore, inside the transmission case 6.6, there is a power transmission chino 11 between the drive shaft 10 associated with the rear wheel differential and the axle 7.
is strung up.

Therefore, the rear wheels 9, 9 are connected via the transmission and rear wheel differential in the transmission case 5, and further through the transmission case 6.
It is driven and rotated by the power of the engine 3 transmitted through the engine 6.

Reference numeral 12 denotes a planting work machine, which is connected to the towing vehicle body 1 by a link mechanism 13 so as to be able to rise and fall freely, and is connected to a seedling stand 14, a center float 15, a side float 16, a planting gear case 17, a planting rod 18, etc. It is composed of

As shown in FIG. 1, the planting rod 18 includes a planting rod 18a for planting seedlings outward from the rear wheel 9, and a planting rod 18a for planting seedlings between the transmission case 6 and the rear wheel 9. 18b and transmission case 6
and a planting rod 18c for planting seedlings between the transmission case 6 and the transmission case 6.

Therefore, as the riding rice transplanter moves forward, the planting rod 18 uses a transmission mechanism to grasp the seedlings on the seedling stand 14 one by one, and as shown in FIG. ．Plant seedlings in a field other than directly behind 6.

Since this invention is constructed as described above, it has the following effects.

(1) At the rear of the towing vehicle body 1, a space is formed by the transmission case 6.6 and the transmission case 5, so a part of the attachment link mechanism 13 of the planting machine 12, the center float 15, etc. is installed in this space. Since it is possible to intervene, the overall length of the riding rice transplanter can be considerably shortened, and miniaturization can be realized.

(2) As the riding rice transplanter moves forward, the rear wheels 9 move up and down, causing the transmission case 6.6 to dig into the mud surface and disturb the mud surface. and rear wheel 9,
9, the planting rod 18 ensures that the seedlings are always planted on a flat mud surface that is not affected by the transmission case 6 or the rear wheel 9, and the seedlings are planted at an extreme depth. There is no chance of the seedlings falling over or falling over.

(3) Since the structure is such that seedlings are planted on both sides of the rear wheels, the width of the propulsion lugs 8 for the rear wheels 9, 9 can be secured by only one row, and a wide propulsion lug can be secured. It can be used and get great traction.

In addition, although a 5-row riding type rice transplanter was shown in the example,
It is not limited to this.
