Description

  The present invention relates to a riding grooving machine that forms a deep groove using the weight of an operator in order to quickly supply and drain water to a paddy field.

  Conventionally, grooving work has been carried out for the purpose of promptly supplying and draining water to the paddy field and cultivating crops well. In the conventional grooving machine, the worker walks while following the grooving machine, the operator strongly presses the triangular plate of the grooving machine against the ground, and is pulled by the driving wheel, so that the cross section has a V shape. The walking type that forms the groove was the mainstream.

  Further, a four-wheel riding grooving machine that uses a four-wheel paddy work vehicle such as a rice planting machine, attaches a plurality of triangular plates to the rear of the working vehicle, and presses the triangular plate against the ground by a lifting device to form a groove is already known.

  A passenger grooving machine that is light and easy to carry has been proposed as disclosed in Patent Document 1. Further, the present applicant has filed a grooving device on August 29, 2003 (Patent Document 2) that can be used by an operator even if it is light and low cost like a walking grooving machine.

Japanese Utility Model Publication No.55-8742 Japanese Patent Application No. 2003-306008

  Grooving work with a four-wheeled paddy paddy vehicle has not yet become widespread in terms of damage to the paddy when entering the paddy field, trampling of seedlings when turning, and price issues. Therefore, although a riding grooving machine that is lightweight and can be easily carried by an operator as in Patent Document 1 has been proposed, in the grooving machine in this Patent Document 1, all the weight of the operator is added to the auxiliary base plate, The bottom surface of the auxiliary base plate must be in contact with the soil on the field surface, and the wheels must pull all the resistance applied to the auxiliary base plate and the operator's weight. No matter how much the weight of the engine or the like is placed above and the weight of the engine and the support pipe is transmitted to the wheel, the wheel does not run idle and it is impossible to perform the grooving operation.

  Moreover, in patent document 1, since the arrangement | positioning with respect to the advancing direction of the number of wheels and a wheel, an auxiliary base plate, and a grooving member is not specified, we are anxious about the problem of rectilinear advance. Presuming from Fig. 1 and Fig. 2, the grooving member is attached to the center of the auxiliary base plate and the wheel is one wheel attached only to the left side of the auxiliary base plate, or the wheels are arranged on both the left and right sides 2 It may be a ring. However, if two wheels are used, it is unlikely that two wheels can be placed between one row of rice, and if the wheel is installed across the rows, the axle position is too low. It will run while defeating rice. Therefore, although it is understood that it is not a configuration with two wheels, it is a configuration with one wheel and there is a difference between the traveling position of the wheel and the traveling position of the grooving member, so that it is possible to go straight or whether it is traveling while tilting. It is not specified.

  In the grooving device previously filed by the present applicant of Patent Document 2 as well, in the case of a single grooving device, the grooving plate travels as much as possible on the trajectory of the wheel. The frame will shift to either the left or right side of the wheel, and if the grooving operation is performed with the operator's riding section directly above the frame, the wheel or grooving plate will tilt to either side and the straightness will deteriorate. In addition, the shape of the groove to be formed also forms V-grooves with different left and right angles, causing one of the grooves created at a steep angle to collapse easily, and the operator to get on the tilted aircraft It was found that physical fatigue occurred.

  In addition, a walking type grooving machine and a grooving machine of Patent Document 1 in which a conventional worker walks while following the grooving machine and pushing the grooving plate downward are directed in the traveling direction. Since the engine is provided in front of the worker, the worker performs the groove cutting work while sucking the exhaust gas of the engine, and the work environment is poor.

  Therefore, the present invention enables grooving work even if an operator gets on the grooving machine without tilting the boarding part (seat surface) or the grooving plate to the left or right, and operates the engine as a power source. The purpose is to maintain the shape of the groove to be created, reduce the fatigue of the worker, and improve the working environment.

  In order to achieve the above object, the present invention proposes a grooving machine according to claims 1 to 3.

That is, the grooving machine 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 an operator straddles substantially between the driving part and the grooving part. Or a riding grooving machine provided with a riding part so that it can be seated on the board, and the center point of the wheel of the driving part, the center with respect to the left and right direction of the riding part, and the apex of the grooving plate of the grooving part , arranged in plan view on a straight line with respect to the traveling direction, and the gearbox of the drive unit, and an engine serving as the power source, a power transmission shaft is disposed on a straight line, the groove behind the riding section relative to the traveling direction A power source is provided above the cut portion .

The grooving machine according to claim 2 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 an operator straddles substantially above the driving part and the grooving part. A riding grooving machine equipped with a riding part so that it can sit on the board, and the tangent line between the wheel of the drive part and the ground, the center of the riding part in the left-right direction, and the apex of the grooving plate of the grooving part , arranged in plan view on a straight line with respect to the traveling direction, and the gearbox of the drive unit, and an engine serving as the power source, a power transmission shaft is disposed on a straight line, the groove behind the riding section relative to the traveling direction A power source is provided above the cut portion .

The grooving machine according to claim 3 is the grooving machine according to claim 1 or 2, characterized in that the wheels of the drive unit are arranged with the upper end inclined to the right with respect to the traveling direction. Is.

  According to the present invention, even if an operator gets on the grooving machine, the grooving machine itself does not tilt to the left or right. It will also improve.

  In addition, since the operator does not board the boarding place at an angle, it works to reduce the fatigue of the worker who performs the grooving work, and the engine that obtains the driving force is also moved backward in the direction of the operator's movement. Since it is arranged, the operator can work in a good environment without exhausting the exhaust gas from the engine.

  FIG. 1 is a side view of a grooving machine according to an embodiment of the present invention. FIG. 2 is a plan view of the grooving machine according to the embodiment of the present invention. 3 is a rear view of the grooving machine according to the embodiment of the present invention, FIG. 4 is a schematic rear view in which the center point of the wheel is arranged at the center line, and FIG. 5 is an arrangement of the tangent line between the wheel and the ground at the center line. FIG.

The wheel of the drive unit 2 of the grooving machine 1 configured to allow the operator 8 to board is the wheel center point 28 (wheel circle) when the wheel 14 is arranged to rotate in the traveling direction. Or the tangent 29 between the wheel and the ground, one or both of which are the carved vertex 16 of the grooved portion 3 and the center of the riding portion 4 (the direction of travel). In this embodiment, the symmetrical left / right center line is a substantially straight line in a plan view with respect to the traveling direction.

  FIG. 1 shows a state in which an operator 8 gets on a grooving machine 1 according to an embodiment of the present invention. The driving unit 2 is provided forward in the traveling direction 23 and the grooving part 3 is provided rearward. Thus, a boarding unit 4 on which an operator 8 sits and rides is provided above a substantially middle part between the drive unit 2 and the groove cutting unit 3. The driving part 2 and the groove part 3 are joined by a frame A5, and the riding part 4 is joined to the frame A5 by a frame B6.

  The drive unit 2 is provided with one wheel 14 cantilevered by a gear box 13 and a plurality of anti-skids 15 so that the wheel 14 does not idle during work. The power source of the wheel 14 is the engine 11, and the wheel 9 rotates by rotating the shaft center 9 by changing the speed of the gear box 13 through the power transmission shaft 12 provided in a part of the frame A 5 from the engine 11. Power is transmitted to 14. The engine 11 is provided behind the wheel 14 with respect to the traveling direction, substantially above the grooved portion 3 and slightly behind the riding section 4 on which the operator 8 sits, and when the operator 8 sits on the riding section 4. It is a position that does not interfere.

  The grooving part 3 prevents the grooving part 7 from entering the left and right grooving plates 7 spreading in a triangular shape with the carving vertex 16 as the apex and the tiller 25 which is a hard soil layer that is not cultivated. Even if the position of the cut vertex 16 is fixed, the rear of the groove plate 7 may be configured to swing slightly to the left and right depending on how the frame A5 and the groove portion 3 are attached. In addition, the cutting vertex 16 cuts the soil 10 which is a soil layer which is close to the ground surface and is generally used for cultivation and which is soft and mainly rooted in rice, and is expanded into a V shape by the groove cutting plate 7 to form a groove. is there.

Boarding portion 4 and the seating surface 20 to board sitting or over the worker 8, the worker 8. be formed from the support member 21 to be part for holding the trench wall cutter 1, the operator on the support member 21 A grip 22 is provided at a position where 8 is naturally held when seated on the seating surface 20. The grip 22 is provided with a rotation adjusting device 26 for adjusting the rotation of the engine 11 serving as a power source or adjusting the rotation of the engine 11 and the transmission of power.

The grooving machine 1 shown in FIG. 2 or FIG. 3 includes both a central point 28 of the wheel of the driving unit 2, a tangent 29 of the wheel and the ground, and a central part in the lateral direction with respect to the traveling direction of the riding unit 4. A state in which the cut vertex 16 of the portion 3 is arranged on a straight line in plan view, that is, on the center line A17 is shown.

In FIG. 2, the gear box 13, the frame A 5, the power transmission shaft 12 provided in a part of the gear box 13, the power transmission shaft 12, and the engine 11 serving as a power source are arranged on a straight line in parallel with the center line A 17. 11 is arranged behind the riding part 4 and above the groove part 3. Further, the power transmission shaft 12, an engine 11 as a power source is disposed on the line of the center line B19 which is provided inside the gear box 13 and the frame A5 and partially also in FIG.

The grooving machine 1 shown in FIGS. 2 and 3 has a configuration in which the gear box 13, the frame A5, the frame B6, the power transmission shaft 12, and the engine 11 are considerably lighter than the weight of the operator 8. Even if the operator 8 gets on the seating surface 20, even if the weight of the operator 8 and the weight of the grooving machine 1 are added together, the center of gravity is located very close to the center line A17. The center line A17 can be kept substantially perpendicular to the cultivator 25.

  The operator 8 straddles the seating surface 20 of the riding section 4, touches both feet to the soil 10 or the tiller 25, and grasps the left and right sides of the grip 22 of the support member 21 with both hands. The rotation adjusting device 26 increases the rotation of the engine 11, transmits power to the wheels 14, and advances the grooving machine 1 in the traveling direction 23. Since the structure of the gear box 13, the frame A5, the power transmission shaft 12 incorporated in a part thereof, and the engine 11 is considerably lighter than the weight of the worker 8, the combined center of gravity of the worker 8 and the grooving machine 1 itself Since the grooving machine 1 does not tilt to the left and right with respect to the traveling direction 23 and the seating surface 20 can always be kept parallel to the soil 10 or the cultivator 25, the operator 8 Stable grooving can be performed.

Note that the tangent line 29 between the wheel and the ground is on the center line A17 , and the trajectory of the wheel 14 is separated and the apex 16 follows and pushes, so that the groove cutting portion 3 reduces resistance for pushing the soil 10 as much as possible. Grooving work can be performed.

In the grooving machine 1 shown in FIG. 4, the center point 28 of the wheel of the drive unit 2, the central part in the left-right direction with respect to the traveling direction of the riding unit 4, and the carving vertex 16 of the grooving part 3 are on a straight line in plan view. The state arrange | positioned on the line of centerline A17 is shown. Since the tangent line 29 between the wheel and the ground is slightly deviated from the center line A17, it is inclined to the left or right with respect to the traveling direction of the wheel itself. In FIG. 4, the upper end of the wheel 14 tilts to the right in the direction of travel, and the center line B19, that is, the gear box 13, the engine 11, the frame A5, and the power transmission shaft 12 built in a part thereof are located inside the groove cutter 1. It is designed to tilt. The tangent line 29 between the wheel and the ground is also positioned to the left of the center line A17 when the traveling direction is viewed in front.

4 is an effective layout when the weight of the gear box 13, the engine 11, the frame A5 and the power transmission shaft 12 incorporated in a part thereof is considerably heavy with respect to the weight of the operator. Since higher above the center line B19 is located inside the gear box 13, the engine 11, the acts to close on the center line A17 of gravity of the power transmission shaft 12 which is built in a part of the frame A5, and the wheels Since the ground tangent line 29 approaches the direction of the center of gravity of the power transmission shaft 12 built in the gear box 13, the engine 11, and the frame A5 and a part thereof, the gear box 13, the engine 11, and the frame A5 and a part thereof are built in. It is easy to balance the weight of the power transmission shaft 12 and the weight of the worker 8, the center of gravity of the sum of the weight of the worker 8 and the grooving machine 1 is near the tangent 29 between the wheel and the ground, and the center line A17 is the soil 10 or the tiller 25 can be kept substantially vertical even during operation.

  The operator 8 straddles the seating surface 20 of the riding section 4, grounds both feet to the soil 10 or the tiller 25, and grasps the left and right of the grip 22 of the support member 21 with both hands. The rotation adjusting device 26 increases the rotation of the engine 11, transmits power to the wheels 14, and advances the grooving machine 1 in the traveling direction 23.

Since the gear box 13, the frame A5 and the power transmission shaft 12 built in a part thereof, and the engine 11 are heavy, the configuration is tilted toward the center of the grooving machine 1 like the center line B19 . When the center of gravity of the configuration of the center line B19 is inward, and the weight of the operator 8, the gear box 13, the power transmission shaft 12 incorporated in the frame A5 and part thereof, and the configuration weight of the engine 11 are added, the groove is cut. If the center of gravity of the machine 1 is arranged so as to be close to the tangent line 29 between the wheel and the ground, the grooving machine 1 itself can be balanced, and the center line A17 can be arranged substantially perpendicular to the soil 10 or the tiller 25. Even if the passenger rides on the seating surface 20, the seating surface 20 becomes horizontal with respect to the soil 10 or the cultivator 25, and the operator 8 can easily board.

In the state shown in FIG. 4, that is, in the state where the wheel center point 28 is arranged on the center line A17 and the tangent line 29 between the wheel and the ground deviates from the center line C24, the wheel 14 itself tilts and deviates from the locus of the wheel 14. Since the cutting apex 16 of the grooving part 3 pushes the soil 10, the resistance of pushing the soil of the grooving part 3 is slightly increased, but the balance of the grooving machine 1 when the operator 8 is on board is excellent and straight ahead It improves the property.

The grooving machine 1 shown in FIG. 5 has a tangent line 29 between the wheel of the drive unit 2 and the ground, a central portion in the left-right direction with respect to the traveling direction of the riding unit 4, and the carving vertex 16 of the grooving unit 3 is a straight line in plan view. That is, it shows a state of being arranged on the center line A17 . Since the center point 28 of the wheel is slightly deviated from the center line A17, it is inclined to the left or right with respect to the traveling direction of the wheel itself. In FIG. 5, the upper end of the wheel 14 tilts to the right in the traveling direction, and the center line B19, that is, the gearbox 13, the engine 11, and the power transmission shaft 12 built in a part of the frame A5 tilt to the inside of the groove cutter 1. It is like that. The wheel center point 28 is also positioned to the right of the center line A17 when the traveling direction is viewed in front.

In the arrangement of the wheels in FIG. 5, the weight of the gear box 13, the engine 11, the frame A <b> 5 and the power transmission shaft 12 incorporated in a part thereof is heavier than that of the first embodiment with respect to the weight of the operator. If it is lighter, the layout is effective. Since the upper part of the center line B19 is arranged on the inner side, the gear box 13, the engine 11, the frame A5 and the power transmission shaft 12 built in a part of the gear box 13 work closer to the center line A17. Since the gravity center of the weight of the engine 11, the frame A5 and the power transmission shaft 12 built in a part thereof approaches the center line A17 , the weight balance is maintained even if the operator 8 gets on the seating surface 20. It becomes easy.

The center of gravity of the combined weight of the worker 8 and the grooving machine 1 is shifted from the center line A17 by the weight of the gear box 13, the engine 11, the frame A5 and the power transmission shaft 12 built in a part thereof. However, depending on the inclination angle of the center line B19 , the combined center of gravity of the operator 8 and the grooving machine 1 is arranged very close to the line of the center line A17. The line A17 can be kept substantially perpendicular to the soil 10 or the cultivator 25.

  The operator 8 straddles the seating surface 20 of the riding section 4, touches both feet to the soil 10 or the tiller 25, and grasps the left and right sides of the grip 22 of the support member 21 with both hands. The rotation adjusting device 26 increases the rotation of the engine 11, transmits power to the wheels 14, and advances the grooving machine 1 in the traveling direction 23.

Since the gear box 13, the frame A5, the power transmission shaft 12 incorporated in a part of the frame A5, and the engine 11 are slightly heavy, the configuration is tilted toward the center of the grooving machine 1 as shown by the center line B19. When the center of gravity of the center line B19 is inward, and the weight of the operator 8, the gear box 13, the power transmission shaft 12 built in the frame A5 and a part thereof, and the component weight of the engine 11 are added, the grooving machine If the center of gravity of 1 is arranged close to the tangent 29 between the wheel and the ground, the grooving machine 1 itself is balanced, and the center line A17 can be arranged substantially perpendicular to the soil 10 or the tiller 25. Even if the user rides on the seating surface 20, the seating surface 20 becomes horizontal and the worker 8 can easily board the vehicle.

Configuration shown in FIG. 5, i.e. the wheel and the ground of the tangent 29 to the line of the center line A17 is disposed, in a state deviated from the center line A17 midpoint 28 of the wheel, a configuration in which the wheel 14 itself is tilted. However, since the apex 16 of the grooving part 3 pushes the soil 10 in the locus of the wheel 14, there is little resistance to push the soil of the grooving part 3, and the grooving machine 1 of the operator 8 when the operator 8 is on board. Excellent balance and good straightness.

  Conventionally, it is well known that grooving operations in paddy fields can be carried out systematically in irrigating and falling water of paddy fields, so that the growth of rice roots is promoted and a strong and high yielding rice that does not fall down is known. However, grooving work is a heavy labor performed during high-temperature and high-humidity periods, and is difficult to incorporate with current farming methods that seek low cost and low labor.

  Therefore, in the present invention, even if it is a passenger type, it is lightweight and can be easily carried, and a function that is further excellent in running balance and straightness is incorporated into a grooving machine that can easily create a deep groove using the weight of the operator. Thus, it is possible to reduce the labor of the operator in the grooving work, and the grooving work can be spread.

  The widespread use of grooving works will promote the growth of rice roots and lead to the production of strong, high-yielding rice that will not surrender. I think.
