DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a groove forming machine mainly used for water supply and drainage after rice planting in paddy rice cultivation management work.

[0002]

2. Description of the Related Art Growing a groove of an appropriate width and depth between the ridges or shores of rice planted in a paddy field, and supplying or draining water to the paddy field according to the growing state of the rice, to grow the rice. Management is taking place. 2. Description of the Related Art Conventionally, a commercially available grooving machine is of a type in which a unicycle is driven forward by an engine, and a soil is pushed right and left by a triangular steel plate attached at the rear.

[0003]

However, according to the above-mentioned prior art, when the soil is hard, the formed grooves are too shallow to have no effect, and when the soil is too soft, the wheels are swollen and it becomes difficult to move forward. After the machine passed through the groove formed by pressing, the soil pressed on both sides slipped into the groove and the groove was buried, which was not practical.

In addition, even when a groove having a sufficient width and depth is formed under appropriate soil conditions, the soil which has been pushed to the left and right rises on both sides of the groove, and has a drawback of inhibiting drainage.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide a continuous and sufficient muddy paddy field. An object of the present invention is to provide a paddy field groove forming machine capable of forming a groove having a width and a depth, and without raising soil on both sides of the groove and obstructing drainage.

[0006]

In order to achieve the above object, according to the present invention, an excavated body in which a plurality of blades are welded to a boss body is projected from a power transmission case described later in a body forward direction. An excavating portion fixed to the provided drive shaft and having a scattering guide plate provided above a side of the excavating body that is rotatably flipped up, and the drive shaft provided below, and protruding above the same in a direction opposite to the forward direction of the fuselage. A power transmission unit including a power transmission case provided with an input shaft, and a cylindrical groove shaper that is long in the front-rear direction is provided on a lower rear surface of the power transmission case and a front end surface portion.
Close contact was made by fixing a groove shaping unit and paddy groove formed having a
In the forming machine, the excavation part, the power transmission part and the groove forming part
Bottom part has approximately the same surface shape, and is serially arranged in the forward direction
It is configured to be connected to .

An input shaft pipe for supporting an input shaft projecting rearward from the upper part of the power transmission case is provided. An engine mounting frame is fixed to a rear end portion of the input shaft pipe, and an engine is installed upward. When the push-forward operating handle is extended rearward and upward from the lower portion of the power transmission case, the weight balance of the body is good and the operability is good.

[0008]

The groove forming machine constructed as described above is placed in a row or a bank of rice planted in a submerged paddy field one to two months after the rice planting, the engine is started, and an operation handle is grasped from behind. When pushing forward against the rice field, the blades of the rotating excavated body scrape off mud and bounce off along the scattering guide plate, and the mud is spread and spread over a wide area.

[0009] at the rear of the drilling unit and the power transmission unit, forward direction
A cylindrical groove shaper that is long in the front-rear direction and is provided by being connected in series toward the direction, receives the operating pressure due to the weight of the body of the engine such as an engine and the human power, and uses the rotating blade plate of the excavation part. Semicircle
Kazunao facing the digging taken the groove bottom wall surface shape in the forward direction
Press and shape so as to apply a linear wall coating. Also, the groove shaper
Since it has a cylindrical shape that is long in the front-rear direction, pitching is suppressed so that the groove depth is constant, and the running of the aircraft is stabilized so that the traveling direction does not swing right and left.

Since the groove shaper is formed in a cylindrical shape, the mud on the upper surface is liable to slide down, so that mud does not accumulate at the time of work and an excessively large operation force is not required. The cylindrical shape is not limited to a circular shape, but may be a polygonal shape. However, it is preferable that the upper surface has no flat portion.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 10 denotes an excavation unit, 20 denotes a power transmission unit, 30 denotes a groove shaping unit, 40 denotes an engine, and 50 denotes an operation handle.

In the excavation part 10, an excavation body 11 in which a plurality of blades 13 are welded to a boss body 12 provided with a key groove or the like in the inner diameter.
Is detachably fixed with a screw or the like to a drive shaft 23 provided to project from the power transmission case 21 toward the body forward direction. As shown in FIG. 4, the wing plate 13 is formed by bending the front base 14 in the body rotation direction forward in the axial rotation direction so as to prevent the muddy soil from scattering forward as shown in FIG. It is preferable that the front end portion 15 in the forward direction of the fuselage is further advanced forward in the rotation direction and curved. A scatter guide plate 16 is provided above the side of the excavating body 11 that is rotatably flipped up so as to diffuse and discharge the mud excavated by the rotation of the excavating body 11 to one side of the fuselage. 21 is fixed with screws or the like.

The power transmission case 21 of the power transmission unit 20 includes:
A drive shaft 23 protruding toward the body forward direction is pivotally supported below, and an input shaft 22 projecting upwardly in the opposite direction (rearward) to the body forward direction is pivotally supported, and the input shaft 22 and the drive shaft 23 are sprockets respectively. 24 and 25 are fitted and the chain 26 transmits rotational power. The operation handle 50 extends rearward and upward from the lower portion of the power transmission case 21, and a rear end portion of the input shaft pipe 27 supporting the input shaft 22 projecting rearward from the upper portion of the power transmission case 21 or an engine mounting frame 41 described later. Connect with and fix firmly.

An engine mounting frame 41 is provided at the rear end of the input shaft pipe 27, and an engine 40 is installed above the engine mounting frame 41.
The rotational power of the engine is transmitted to an input shaft 22 projecting upward and rearward of a power transmission case 21 using an appropriate power transmission means, for example, a pulley, a V-belt, or the like. 42 is a belt cover.

Reference numeral 31 denotes a groove shaper. In this embodiment, the body weight is reduced as much as possible to improve operability, and in order to stabilize sliding performance, a synthetic resin-made front-rear direction is used.
Using a long cylinder, the lower rear surface of the power transmission case 21
The front end face of the cylinder is closely adhered and fixed with screws or the like, a styrofoam molding material 32 is fitted into the inside of the cylinder, and the rear end is closed with a closing plate 33 to prevent intrusion of mud and water.
Also, the lower bottom of the excavation body 10, the lower bottom of the power transmission case 21 and the lower bottom of the groove forming section 30 have substantially the same plane shape, and
They are connected in series.

[0016]

The groove forming machine for paddy fields according to the present invention is constructed as described in the above embodiments, so that grooves having a sufficient width and depth can be continuously formed, especially in paddy fields where the soil is soft and muddy. Then, there is no possibility that the soil is raised on both sides of the groove to hinder drainage. Further, since the body weight is light and the balance is good, handling is easy, and operability during the groove forming operation is good.
