Description

  The present invention relates to a riding-type grooving device for forming a groove for quickly supplying and draining water to a farm field.

  Conventionally, grooving work has been carried out for the purpose of promptly supplying and draining water to the field (paddy field) and improving the growth of crops. Grooving machines that form a groove by attaching a triangular plate to the rear and pulling the triangular plate against the ground while an operator presses the triangular plate are the mainstream. In addition, a grooving machine in which a plurality of grooving plates are attached to the rear of a four-wheel working machine such as a rice transplanter and the grooves are formed while being pressed against the ground is well known.

  As shown in Japanese Utility Model Laid-Open No. 64-19654, the grooved plate is shaped as an abacus, or as in Japanese Utility Model Publication No. 62-60101, the weight of the engine is added to the drive wheels to increase the propulsive force. Grooves can be formed even if the soil of the paddy field is slightly hardened, or a groove cut portion is provided on the bottom surface of an auxiliary base plate on which an operator can ride, as in Japanese Utility Model Publication No. 55-8742. A grooving machine on which a person rides and cuts a groove is already known.

Japanese Utility Model Publication No. 64-19654 Japanese Utility Model Publication No. 62-60101 Japanese Utility Model Publication No. 55-8742

  Grooving work on a four-wheel work machine for passengers is easy for the operator. However, it is difficult to step on the rice during turning and the connection between the grooves, or when the work machine enters or leaves the paddy field. There are many problems such as breaking, but it has not yet spread.

  The grooving machine devised so that it can work even if the soil of the paddy field becomes slightly hard, as in the above-mentioned walking type patent documents, Japanese Utility Model Laid-Open No. 64-19654 and Japanese Utility Model Laid-Open No. 62-60101, The work to press the ground onto the ground will be undertaken by the operator in the end, so it cannot be said that it is an easy work. In Japanese Utility Model Publication No. 55-8742, the center of gravity of the operator is behind the grooved plate although it is a passenger. Therefore, there is a high possibility that the drive unit idles, and it is necessary to increase the weight of the drive unit in order to prevent idling. An increase in the weight of the grooving machine itself makes the machine difficult to handle, so it is difficult to say that good grooving work can be performed.

  Accordingly, the present invention provides a riding type grooving device that can be rided by an operator and is as light as a walking type, and that can form an even and deep groove using the weight of the operator while riding. With the goal.

  In order to achieve the above object, the present invention proposes a riding type grooving apparatus according to claims 1, 2 and 3.

That is, the riding type grooving apparatus according to claim 1 is provided with a driving part in the front and a grooving part in the rear with respect to the traveling direction of the machine body, and is configured so that an operator can board. The boarding place that is located between the drive part and the groove part of the fuselage and extends long in the front-rear direction so that the operator can slide across the straddle position across the drive part and the groove part. It is provided with rear and moreover groove switching thereof below the boarding location of the engine operator to drive the driving unit provided in the rear end of the power transmission shaft extending below the operator boarding location from the front of the drive unit to the rear It is characterized by being positioned above the portion .

Further, the riding type grooving device according to claim 2 is the gearbox provided on the rotating wheel of the driving wheel and the rotating shaft of the shaft center thereof, wherein the driving unit rotates to advance the machine body in the traveling direction. from made, it is characterized in that it comprises an engine at the rear end of the power transmission shaft extending below the boarding location of the worker from the gearbox to the rear.

  Furthermore, the riding type grooving device according to claim 3 is the one according to claim 1 or 2, wherein the drive unit is provided with a protective plate for protecting the leaf or stem of the rice from being caught in the driving wheel by the direction of the body. It is characterized by that.

  According to the present invention, since the center of gravity of the worker is between the drive unit of the grooving device and the grooving device, a uniform and deep groove can be easily formed by using the weight of the worker while riding. I can do it. Since the worker can easily move back and forth on the boarding place, the center of gravity of the worker can adjust the weight distribution with respect to the front and rear grounding parts, the paddy field is weak, and the groove formed by the groove cutting part becomes too deep In some cases, when the drive unit runs idle and the work implement does not advance, the depth of the groove is reduced by moving the center of gravity of the worker toward the drive unit to reduce the weight applied to the groove cutting portion. The weight applied to the drive unit of the work machine is increased to amplify the contact pressure, and the wheel can be driven well without idling.
