Description

  The present invention relates to a grooving machine that can perform grooving work for paddy fields while riding and can smoothly form grooves even if the traveling direction is changed.

  Among the grooving machines, the riding type has a grooved plate installed at the rear of a moving body of a four-wheeled vehicle (Patent Document 1), and a seat for the operator is provided between the drive wheel and the grooved plate. A thing on which an operator gets on (Patent Document 2) has been put into practical use.

  In addition, although not put into practical use, there is one that can freely change the traveling direction while riding (Patent Document 3).

  However, the four-wheeled vehicle described in Patent Document 1 has many crops that are crushed because the four drive wheels simultaneously turn when turning at the end of the work surface, and the storage location when not in use also requires an area equivalent to one passenger car. To do.

  The grooving operation by the riding type of Patent Document 2 often cannot be performed unless the weight of the operator is applied to the grooving plate and the resistance against the ground against the travel is not greatly pushed.

  In addition, although it has a handle, it does not have a steering function and must be lifted when changing the direction at the end of the work surface, which is a burden on the operator.

  The steering type that can be steered in Patent Document 3 has not been put into practical use, but it seems that there are many cases where it is not possible to travel unless the weight of the operator and the weight of the power equipment are applied to the grooving plate and the resistance to travel is not greatly pushed. .

  Further, there is no function of adjusting the groove depth by changing the weight distribution of the worker applied to the drive wheel and the groove portion by moving the boarding position.

  Accordingly, the present invention proposes a riding grooving machine that is excellent in running performance and maneuverability, and that can easily form clean grooves without burdening workers and crops.

  In order to achieve the above object, a riding grooving machine according to the present invention includes a seat and a rotating body on which a worker rides on a front frame provided with a traveling drive system including an engine, a clutch, and drive wheels, and a steering handle. And a rear frame comprising a grooved portion including a mudguard plate and a mud plate, and the front frame and the rear frame are connected by a rotatable joint so as to be steerable.

  In addition, the rotation center axis of the engine, clutch, handle, and drive wheel is arranged in front of the rotation center axis of the front frame with respect to the rear frame, so that the seating position can be changed back and forth with respect to the traveling direction from the rotation center axis. Seated seats for the elderly.

  In addition, the rear part is a mudguard plate that acts to remove mud or soil on the side of the rotor and the side of the rotor in the direction of travel and mud that adheres to the rotor, or a mudboard that acts to scrape the soil. Equipped with structured grooving.

  In the riding grooving machine according to the present invention configured as described above, a seat and a rotating body on which an operator rides on a front frame provided with a traveling drive system including an engine, a clutch, and driving wheels, and a steering handle. , Equipped with a rear frame composed of a grooved portion including a mudguard plate and a mud plate, and the front frame and the rear frame are connected by a rotatable joint, so that the direction of travel can be easily changed only by operating the handle. I can do it.

  Since the center axis of the drive wheel is arranged in front of the rotation center axis of the front frame with respect to the rear frame, the linearity of the grooving machine can be secured by the traction force of the drive wheel during traveling.

  In addition, an engine, a clutch, and a handle are arranged in front of the rotation center axis of the front frame with respect to the rear frame, and a seating seat for an operator that can change the seating position back and forth with respect to the traveling direction is installed from the rotation center axis. Therefore, the operator can easily change the weight distribution of the driving wheel and the rotator for grooving to adjust the depth of the groove.

  The grooving part is a rotating body and mud on the side of the rotating body, or a mudguard plate that removes the soil laterally with respect to the direction of travel and a mud that adheres to the rotating body, or a mud plate that scrapes off the soil. The rotary body bites into the ground to form a groove, and the rotary body head surface contacts the ground to reduce the resistance related to running generated in the groove cut portion.

  In addition, the mudguard plate installed on the side of the rotating body removes mud or soil adhering to the side of the rotating body from the side of the rotating body in the direction of travel, making the rotating body easy to rotate and eliminated. Mud or soil creates the side walls of the trench.

  In addition, a mud plate that covers the rotating body is installed at the lower back of the rotating body to prevent mud adhering to the rotating body or soil from falling into the groove formed by running the grooving machine and inhibiting the formation of the groove. The mud or soil is scraped off at the bottom of the rotating body to protect the formed groove and form the bottom surface of the groove.

  The mudguard plate and the mud plate are installed from the outer periphery of the rotating body on the vertical line from the ground to the central axis of the rotating body, thereby reducing the lateral pressure to the grooved portion that occurs when the casing turns, Even when turning, the chassis can easily travel.

  Next, embodiments of the present invention will be described with reference to the drawings.
