Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a ride-on paddy field ditching machine. Background Technology

[0002] Ditching in paddy fields is a key measure to ensure crop growth before rice planting. The core is to create a suitable water, air, fertilizer, and heat environment for rice by constructing a field irrigation and ventilation system. This can quickly drain rainwater during the rainy season to prevent flooding and protect the root system, while also improving the soil environment, enhancing soil aeration, activating aerobic microorganisms to improve fertility, and reducing the accumulation of toxic substances in anaerobic environments. To save manpower, ditching machines are generally used when ditching paddy fields.

[0003] An improved paddy field ditching machine, as proposed in authorization announcement number CN215601784U, includes a frame with a front fork sleeved at the front end. A spring is provided between the frame and the front fork. A handlebar is connected to the upper end of the front fork, and a reducer is connected to the lower end. One end of the reducer is connected to a paddy field wheel, and the other end is connected to an engine. The ditching machine uses a gasoline engine as a drive to drive the paddy field wheel to rotate and drive the frame to move. Then, the ditching shovel at the rear of the frame is used to perform ditching operations.

[0004] Although the equipment is equipped with a seat for the operator, the complex working environment of paddy fields, such as differences in the flatness of the field surface and the unevenness of the soil, requires the operator to continuously adjust the balance of the machine by supporting the field surface with their legs in order to maintain the stable working posture and consistent ditching depth of the ditcher. This working method not only requires a high level of skill and physical coordination from the operator, but also easily leads to excessive physical exertion of the operator due to prolonged leg sliding support, thereby reducing the efficiency of ditching operations. To overcome the above problems, we provide a riding paddy field ditcher. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 In this embodiment of the utility model, a ride-on paddy field ditching machine includes a frame 1. One end of the frame 1 is rotatably connected to a steering shaft, the lower end of the steering shaft is fixedly connected to a front wheel frame 5, and the upper end of the steering shaft is fixedly connected to a steering handle 3. A paddy field wheel 6 is rotatably connected inside the front wheel frame 5. The front wheel frame 5 is provided with a drive assembly for driving the paddy field wheel 6 to rotate. During operation, the drive assembly drives the paddy field wheel 6 to rotate, and the rotation of the paddy field wheel 6 provides the power to move the frame 1. The steering handle 3 can adjust the direction of the paddy field wheel 6, which facilitates the control of the direction.

[0027] Please see Figures 1-3 The drive assembly includes a gasoline engine 4, which is mounted on the upper platform of the front wheel frame 5. A reducer 12 is mounted on the lower end of the front wheel frame 5. The output shaft of the reducer 12 is connected to the axle of the paddy field wheel 6.

[0029] Please see Figure 6 and Figure 7The frame 1, away from the front wheel frame 5, is fixedly connected to a middle slide plate 9. The lower end of the middle slide plate 9 is provided with a grooved assembly, which includes a T-shaped base block 23 and a grooved base box 10. The T-shaped base block 23 is fixedly connected to the middle of the lower end face of the middle slide plate 9. The upper end of the grooved base box 10 has a sliding groove 20 that matches the T-shaped base block 23, and the sliding groove 20 is slidably connected to the T-shaped base block 23. Matching mounting holes 21 are provided at both ends of the middle slide plate 9, the T-shaped base block 23, and the grooved base box 10 on the side away from the frame 1. Bolts 22 are installed between the mounting holes 21 on the middle slide plate 9, T-shaped base block 23 and ditching base box 10. The ditching base box 10 can sink into the mud of the paddy field during operation, and then dig the paddy field under the dragging action of the frame 1. When the ditching base box 10 needs to be replaced, the bolts 22 can be removed first, and then the ditching base box 10 can be slid off the T-shaped base block 23 to complete the disassembly. During assembly, the sliding groove 20 on the ditching base box 10 is slid onto the T-shaped base block 23, and then the bolts 22 are used to lock it.

[0030] Please see Figure 2 The middle slide plate 9 is rotatably connected to the side slide plates 8 by rotating brackets on both sides. The end of the trench bottom box 10 near the gasoline engine 4 is inclined. The ends of the middle slide plate 9 and the side slide plates 8 near the gasoline engine 4 are both curved upwards. The upwardly curved middle slide plate 9 and the side slide plates 8 can move more smoothly on muddy ground.

[0031] Please see Figure 4 and Figure 5The frame 1 is provided with a support assembly for supporting the side slide plate 8. The support assembly includes two support arms 11, which are rotatably connected to the two sides of the tail end of the frame 1. A U-shaped frame 16 matching the end of each support arm 11 is fixedly connected to the upper surface of the side slide plate 8. A locking hole 19 is provided at the end of each support arm 11 away from the frame 1. A fixing frame 15 is fixedly connected to one side of the U-shaped frame 16. An L-shaped locking rod 14 that mates with the locking hole 19 is slidably connected inside the fixing frame 15. An avoidance hole that mates with the L-shaped locking rod 14 is provided on the U-shaped frame 16. A limit slider 18 is fixedly connected to the L-shaped locking rod 14 inside the fixing frame 15. The L-shaped locking rod 14 is located away from the U-shaped frame 15 from the limit slider 18 and the fixing frame 15. A return spring 17 is sleeved between one side of the frame 16. When locking and supporting the side slide plate 8, first unfold the side slide plate 8, then pull the L-shaped locking rod 14 so that the end of the L-shaped locking rod 14 exits from the U-shaped frame 16. Then place the end of the support arm 11 into the U-shaped frame 16. After placement, release the L-shaped locking rod 14. Under the action of the return spring 17, the L-shaped locking rod 14 is inserted into the lock hole 19 to lock the support arm 11. After the support arm 11 is locked, the side slide plate 8 can be locked. When it is necessary to fold the side slide plate 8, pull the L-shaped locking rod 14 so that the end of the L-shaped locking rod 14 is pulled out from the lock hole 19. After pulling it out, the end of the support arm 11 can be taken out from the U-shaped frame 16. After the end of the support arm 11 is taken out, rotate the support arm 11 and the side slide plate 8 to fold it.

[0032] The working principle of this utility model is as follows: During operation, the gasoline engine 4 on the upper platform of the front wheel frame 5 provides power. The belt pulley type automatic centrifugal clutch 24 transmits power to the transmission belt 13. Through the transmission belt 13, the power is transmitted to the transmission pulley of the input shaft of the reducer 12. After the reducer 12 reduces speed and increases torque, its output shaft drives the paddy field wheel 6 to rotate. The paddy field wheel 6 contacts the mud and generates traction force to drag the frame 1 to move. The operator can adjust the direction of the paddy field wheel 6 through the steering handle 3 at the upper end of the steering shaft to achieve travel control. When digging a ditch, the ditching bottom box 10 sinks into the mud under the action of the machine's weight and forms a ditch under the dragging action, thus realizing ditching. The upward curved structure of the middle slide plate 9 and the two side slide plates 8 can reduce the resistance of the mud and make the movement smoother. At the same time, the seat cushion 2 on the frame 1 is for the operator to sit on, and the footrest 7 supports the feet to ensure comfortable and stable operation.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
