Description

Technical Field

[0001] The utility model relates to the field of agricultural automation production, in particular to a miniaturized mowing and paving machine transmission system. Background Art

[0002] Sugarcane harvesting is divided into manual harvesting and mechanical harvesting. Manual harvesting requires manual cutting, leaf stripping and baling, and manual harvesting efficiency is low; mechanical harvesting usually uses large combine harvesters for harvesting, which has high harvesting efficiency, but high investment costs, large working space required, and is greatly affected by terrain and weather. Especially in the hilly areas in the south, large combine harvesters cannot enter uneven fields or narrow fields for harvesting. Sugarcane is generally planted on ridges, and there is space between sugarcane ridges. Large harvesters cannot use the space between ridges for harvesting. Therefore, there is an urgent need for a miniaturized harvester that can enter the ridges for harvesting. However, traditional large harvesters mainly use mechanical transmission to drive the gearbox to achieve the movement of the working device, which has the problems of complex and large structure, and it is difficult to achieve miniaturization.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1-4As shown, the transmission system of the miniaturized mower and paving machine in this embodiment includes: a power source 1; a relay shaft 2; a hydraulic station 3; a gearbox 4; a traveling device 5; a first transmission belt 6 and a second transmission belt 7; wherein the first transmission belt 6 connects the output shaft 23 of the power source 1 and the relay shaft 2, the relay shaft 2 is connected to the hydraulic pump 22 of the hydraulic station 3, the second transmission belt 7 connects the relay shaft 2 and the input shaft 25 of the gearbox 4, and the output shaft 26 of the gearbox 4 is connected to the traveling device 5. In this embodiment, the power source 1 is a fossil energy engine, but is not limited to this embodiment, and can also be a power source of an electric motor or other new energy sources. This embodiment also includes a harvesting device, and the hydraulic station 3 drives the harvesting device to harvest sugarcane. For example, the harvesting device is a rotary cutter arranged at the tail of the mower and paving machine, and the rotary cutter is driven by a hydraulic motor. The hydraulic station 3 drives the hydraulic motor to rotate, and the power source 1 provides power for the mower and paving machine to travel and the harvesting device to harvest sugarcane.

[0027] The transmission mode of the traditional harvester is that the power source 1 transmits power to the traveling device 5 and the harvesting device after passing through the gearbox 4, and the gearbox 4 bears all the power output. In this way, a high-power gearbox 4 needs to be designed, which is very large and not suitable for small mowers. In this embodiment, the power output by the power source 1 is distributed to the hydraulic station 3 and the gearbox 4 through the relay shaft 2. The hydraulic station 3 bears the power of the harvesting device, and the gearbox 4 only needs to bear the power of the traveling device 5. The mower is usually transported to the field by a trailer and then goes to the field for harvesting. Its traveling power is small. The design of the utility model greatly reduces the size of the gearbox 4, thereby greatly reducing the overall size of the mower, making it more conducive to harvesting between ridges.

[0028] In this embodiment, the input shaft 24 of the hydraulic pump 22 of the hydraulic station 3 is directly used as the relay shaft 2. This can save a transmission stage and further reduce the volume of the entire system, but is not limited to this embodiment, and other methods can also be used to connect the relay shaft 2 and the hydraulic station 3.

[0029] The relay shaft 2 is provided with a relay pulley 1 8 and a relay pulley 2 9, the output shaft 23 of the power source 1 is provided with a driving pulley 10, the input shaft 25 of the gearbox 4 is provided with a speed change pulley 11, the first transmission belt 6 connects the driving pulley 10 and the relay pulley 1 8, and the second transmission belt 7 connects the relay pulley 2 9 and the speed change pulley 11.

[0030] like Figure 3 As shown, this embodiment further includes a tensioning device 12, which includes a support arm 14, a rotating shaft 13, and a lifting rod 15. One end of the support arm 14 is mounted on the rotating shaft 13, and the other end is provided with a tensioning wheel 16. The lifting rod 15 is connected between the two ends of the support arm 14. The support arm 14 can rotate relative to the first transmission belt 6 or the second transmission belt 7 by relying on the rotating shaft 13, so as to press and tension the first transmission belt 6 or the second transmission belt 7.

[0031] The first transmission belt 6 and the second transmission belt 7 are located on both sides of the relay shaft 2, the rotating shaft 13 is located between the first transmission belt 6 and the second transmission belt 7, the tensioning device 12 includes two support arms 14, each support arm 14 is equipped with a lifting rod 15, the tensioning wheel 16 of one support arm 14 abuts against the first transmission belt 6, and the tensioning wheel 16 of the other support arm 14 abuts against the second transmission belt 7. Figure 4 As shown, the relay pulley 1 8 is close to the relay pulley 2 9, and the two support arms 14 in the tensioning device 12 share a rotating shaft 13, further reducing the volume. Figure 2 , 3 As shown, the first transmission belt 6 and the second transmission belt 7 are in an inverted V shape, and the tensioning device 12 is located inside the inverted V shape, which saves space for the tensioning device 12 and can compress the distance from the front to the rear of the vehicle. Even if the sharp corners of the inverted V shape protrude upward, the setting of the driving position 21 allows the driver's legs to straddle both sides of the inverted V shape, similar to the posture of riding a horse. On the basis of saving space, it can not only increase the stability of the ride, but also does not affect the normal operation of the driver.

[0032] like Figure 1 , 2 As shown in Figures 1 and 4, the power source 1, the hydraulic station 3, and the gearbox 4 are arranged in sequence from the front to the rear of the vehicle. The transmission scheme of this embodiment is adopted, the hydraulic station 3 is located between the power source 1 and the gearbox 4, and the main power mechanism is arranged in the center of the mower and paving machine, and the driver sits on it, which not only conforms to the transmission connection structure of this embodiment, but also facilitates the setting of the driving position 21 that conforms to the driver's ergonomics, and can further reduce the overall volume and save space.

[0033] The walking device 5 includes a crawler track 18 and a guide wheel 19 for tensioning the crawler track 18 . A plurality of guide wheels 19 may be provided as required. The output shaft 26 of the gearbox 4 is provided with a driving wheel 20 , which is meshed and docked with the crawler track 18 .

[0034] The input shaft 25 and the output shaft 26 of the gearbox 4 are arranged in sequence from the front to the rear of the vehicle.

[0035] This embodiment further includes a driving seat 21 , which is mounted on the gearbox 4 .

[0036] In this embodiment, the crawler 18 is a triangular crawler, which is stretched into a triangle by the guide wheel 19 and the drive wheel 20. The drive wheel 20 is located at the top of the triangle and is stored under the driver's seat 21. Figure 1 As shown, the triangular crawler is approximately an oblique triangle, the top of the triangular crawler is inclined toward the rear of the vehicle, and the driving wheel 20 is stored in the Figure 1Within the scope of the driving position 21 shown, as long as it does not affect the driver's getting on and off the vehicle, the overall volume of the mower can be reduced as much as possible. It is not necessary to require that the left and right sides of the driving position 21 completely cover the driving wheel 20.

[0037] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
