Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter in which a seedling planting device is interlocked and connected to the rear of a traveling body equipped with lug wheels.

In the conventional rice transplanter, the front and rear lug wheels are arranged with approximately the same distance between the ruts, and furthermore, the propulsion lugs are provided protruding from both sides of the annular wheels. As a result, the mud that was lifted by adhering to the propulsion lugs falls intermittently, creating unexpected irregularities on the planned seedling planting path adjacent to the wheels, and even after leveling the land, the planting area remains unsteady. Differences in hardness and softness occurred, causing problems such as floating seedlings and poor planting.

Additionally, it is generally desired that rice transplanters be able to make sharp turns to increase the planting area as much as possible and increase productivity, and to be able to run stably by reducing side-to-side tilting of the machine body due to irregularities in the running ground.

In view of the above-mentioned circumstances, the present invention rationally configures the lug wheel and its attachment, and avoids the occurrence of poor planting due to mud falling from the lug without reducing the propulsion force. The aim is to meet the aforementioned demands.

Next, embodiments of the present invention will be described in detail based on the drawings.

A seedling planting device 4 is installed at the rear of a traveling body in which a pair of left and right driving steering front lug wheels 1, 1 and a driving rear lug wheel 2, 2 are mounted on an axis, and a control section 3 is provided, and a seedling planting device 4 is installed so as to be movable up and down. It consists of a type rice transplanter.

Of the lug wheels 1 and 2, the lug wheel 1 on the front side of the fuselage has propulsion lugs 6 protruding only inward from the annular wheel body 5, and the lug wheel 2 on the rear side is propelled only outwardly on the annular wheel body 5. The lugs 6 are provided protrudingly and are located on the outer side of the machine body than the lug wheels 1 on the front side, and the respective annular wheels 5, The lug wheels 1 and 2 are provided with their 5 sides close to each other.

Furthermore, as an example of the distance from the planned seedling planting locus L when viewed from the front of the front and rear wheels 1 and 2, as shown in FIG. The distances A and A are each 50 mm, and the protrusion amount B ₁ of the lugs 6 on the front wheel 1 is about 50 mm, and on the other hand, the protrusion amount B ₂ of the lugs 6 on the rear wheel 2 is about 90 mm, Overall lag 6,6...
The distance C between the edges of the rice transplanter is approximately 240 mm, and when loading and unloading the rice transplanter on a transport vehicle, etc., by using concave footboards 7 with a width of approximately 300 mm, the rice transplanter can be loaded and unloaded without accidental falling. , the lugs 6... can be loaded and unloaded smoothly while avoiding collision with both edges of the footboard 7.

In summary, the present invention provides the rice transplanter described at the beginning, in which the lug wheel 1 on the front side of the machine body among the lug wheels 1 and 2 has a propulsion lug 6 protruding only inward from the annular wheel body 5, and the rear The side lug wheel 2 has a propulsion lug 6 protruding from the annular wheel body 5 only on the outside, and
Each of the annular wheels 5 is positioned on the outer side of the machine body than the lug wheel 1 on the front side, and the annular wheels 5, 5 side are brought close to the planned seedling planting locus L by the seedling planting device 4. It is characterized by being provided with lug wheels 1 and 2.

In other words, although the propulsion lug 6 is installed so as to protrude only to one side from the outer periphery of the annular wheel 5 to provide sufficient propulsive force, when the wheels 1 and 2 are installed, the annular wheel 5 side is Since it is placed adjacent to the planned planting trajectory L, it is possible to avoid mud adhering to the propulsion lugs 6 from falling onto the planned seedling planting trajectory L, and seedlings can be planted successfully.

Since the distance between the front and rear lug wheels 1 and 2 is set so that the rear lug wheel 2 is located on the outer side of the aircraft body than the front lug wheel 1, the front wheel 1, which is a steering wheel, Although the narrow distance between ruts allows for sharp turns, the rear wheels 2 have a wide distance between ruts.
As a result, even if the running ground is uneven, it is possible to prevent the aircraft from tilting to the left or right as much as possible and to be able to run stably.

In addition, although the distance between the ruts of the front and rear wheels is different, since they are close to each other, the only footboard used when loading onto the truck bed is a single footboard with a relatively narrow width on one side. Since the front and rear wheels can pass through it, it has the advantage of being easy to handle.

Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
