Description

[Detailed explanation of the idea] The present invention relates to an improvement of a rice transplanter.

Generally, rice transplanters are equipped with guide rails that protrude laterally from the left and right sides of the machine to guide the seedling platform back and forth in the horizontal direction perpendicular to the direction of travel, so the rice transplanter can change direction at the edge of the harbour. In such cases, the protruding end of the guide rail often collides with a ridge or the like and is damaged.

The present invention prevents damage to the protruding ends of the guide rails against the seedling stand by providing side bumpers on the left and right sides of the rice transplanter, and when this is applied to a six-row riding type rice transplanter. To explain the embodiment drawings, in the drawing, 1 indicates that brackets 4 and 5' projecting above and below the rear end of the front body 2 and brackets 5 and 4' projecting above and below the front end of the rear body 3 are the same. on the vertical line of pin 6.
It shows a traveling aircraft configured to be able to be bent horizontally by pivoting 6 and 7 on the horizontal line, with both the front and rear aircraft 2,
On both left and right sides of the swing arm 13 are wheels 11, 11 and 12.12 to which power is transmitted from an engine 8 mounted on the rear fuselage 3 via a bendable shaft 9°10 mounted between the two bodies. , 13.14°14, and is attached to a gate-shaped frame 15 erected from the front fuselage 2. By rotating the handle 170 in front of the seat 16, the steering gear box 18, It is configured to steer by adjusting the bending direction and bending degree of both bodies 2 and 3 via a focusman arm 19 and a rod 20, and the front end of the front body 2 is driven and rotated by an engine 8. PTO
A shaft 21 is provided.

22 is a pair of lower links 2 in front of the front fuselage 2.
3 and one top link 24 for vertical movement. are arranged in parallel, and the conduction cases 25 are connected by a tubular member 29°29, and on the upper surface of each conduction case 25. A seedling stand 31 is provided by this guide rail 30, and the guide rail 30
Both ends 30', 30' protrude outward from the side surface of the seedling stand 31.

Further, power is transmitted to the input shaft 32 of the seedling planting device 220 via a telescoping shaft 33 that connects with the PTO shaft 21.

34 is a bumper located in front of the seedling planting device 22, and the bumper 34 is attached to each conductive case 25 so as to connect each seedling planting unit 28.

Reference numerals 35 and 35 indicate side bumpers located on the sides of the seedling planting device 22 and corresponding to the protruding ends 30' and 30' at both ends of the guide rail 30, and the side bumpers 35 and 35 correspond to the protruding ends at both ends of the guide rail 30. 30′ in a planar view, it has a U-shape so as to surround the front, rear, and outer three sides, and is disposed at approximately the same height as the guide rail 30;
Its front inner end is fixed to the bumper 34 which is attached to the conduction case 25 and constitutes two parts of the machine frame, and its rear inner end is fixed to the conduction case 25 which constitutes the machine frame of the seedling planting device 22. installed.

In addition, both side bumpers in this example are 35.35
are removably attached to the bumper 34 at one end and the conduction case 25 at the other end, and the side bumper 35.
35 to the protruding end 30' of the guide rail 30, 3
It may be attached to 0'.

In this way, the protruding end 3 of the guide rail 30 of the seedling stand 31
A side bumper 35.35 that surrounds the front, rear, and outer three sides of 0' and 30' is arranged at approximately the same height as the guide rail 30, and the front inner end of the side bumper 35 is used to place seedlings. The protruding end 3 of the guide rail 30 is attached to the machine frame located in front of the stand 31 by fixing the rear inner end to the machine frame located behind the seedling stand 31.
0' is protected by its outer side and front and rear side bumpers 35.

In this case, since the side bumper 35 of the present invention is fixedly attached to the machine frame at both ends, it has a gate-shaped rigid frame structure with both ends fixed to the machine frame. Even if the side bumper approaches a ridge, etc. and collides with the ridge, etc., the side bumper, which has a gate-shaped rigid-frame structure with fixed fulcrums at both ends, will not easily deform, and the protruding end 30 of the guide rail will directly collide with the ridge, etc. It definitely prevents this from happening.

Therefore, according to the present invention, it is possible to avoid damage to the guide rail due to a collision with a ridge or the like during rice planting work on the edge of a ridge or change of direction at the edge of a ridge, thereby improving durability.

In addition, if the dimension S from the outermost seedling planting claw 26 to the side bumper 35 is made approximately equal to the row spacing T between each seedling planting claw 26, both side bumpers 35 and 35 will be placed on the side of the adjacent planting row. Becomes a marker.

Furthermore, it goes without saying that the present invention is applicable not only to riding-type rice transplanters but also to traveling-type rice transplanters.
