Detailed Implementation

[0026] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0027] See Figure 1 As shown, the sugarcane cleaning equipment used in the hydraulic power system of this utility model includes a feeding ladder b, a cutting device c, a cleaning device e, and a uniform loading ladder f. The feeding ladder b, the cutting device c, the cleaning device e, and the uniform loading ladder f are all integrated on the frame assembly a.

[0028] See Figure 2-3As shown, this utility model discloses a hydraulic power system for a sugarcane impurity removal device, including a feeding ladder motor 1, a cutting device motor, an impurity removal device motor 3, and a uniform loading and unloading integrated ladder motor 4. All of these motors are hydraulic motors, driving the feeding ladder b, cutting device c, impurity removal device e, and uniform loading and unloading integrated ladder f respectively. This fully hydraulic drive provides better stability. The hydraulic power system also includes a hydraulic oil tank 5, a power source, and a driver. The driver has three interfaces: a hydraulic oil tank 5, a power source 5, and a driver unit 5. The device has an input end, a power input end, and a liquid output end. The liquid input end of the driver is connected to the hydraulic oil tank 5. The liquid output end of the driver is connected to the feeding ladder motor 1, the cutting device motor, the impurity removal device motor 3, and the material leveling and loading integrated ladder motor 4 respectively through a hydraulic oil distributor. This is used to draw hydraulic oil from the hydraulic oil tank 5 into the corresponding pipelines of the feeding ladder motor 1, the cutting device motor, the impurity removal device motor 3, and the material leveling and loading integrated ladder motor 4. The output end of the power source is connected to the power input end of the driver through the transmission system to provide power to the driver, and then to the entire impurity removal equipment. Specifically, the power source can be a tractor, an engine, or a drive motor, with multiple power input options for greater convenience.

[0029] This utility model's hydraulic power system transmits power to the feeding ladder motor, cutting device motor, impurity removal device motor, and integrated material loading ladder motor via a transmission system and hydraulic oil distributor. It can be driven by a tractor, engine, or drive motor. In actual use, users can select the most suitable power source based on their actual needs and budget, ensuring continuous operation and optimizing cost management. This significantly enhances the application range and operational flexibility of the sugarcane impurity removal equipment. Furthermore, its fully hydraulic drive provides superior equipment stability.

[0030] Preferably, the hydraulic oil distributor includes a first directional valve 6, a second directional valve 7, and a third directional valve 8. Each of these valves has four ports: A, B, P, and T. Ports A and B of the first directional valve 6 are connected to the feeding elevator motor 1 and the cutting device motor, port T is connected to the hydraulic oil tank 5, and port P is connected to the liquid output terminal of the driver. Ports A and B of the second directional valve 7 are connected to the material leveling and loading integrated elevator motor 4, port T is connected to the hydraulic oil tank 5, and port P is connected to the liquid output terminal of the driver. Ports A and B of the third directional valve 8 are connected to the impurity removal device motor 3, port T is connected to the hydraulic oil tank 5, and port P is connected to the liquid output terminal of the driver. The system supplies oil to the feeding elevator motor 1, the cutting device motor, the impurity removal device motor 3, and the material leveling and loading integrated elevator motor 4 through three reversing valves.

[0031] like Figure 4 As shown, the cutting device c includes a first cutting roller 32, a second cutting roller 33, a fixed roller 34, and a floating roller 35. The cutting device motors include a first cutting roller motor 11, a second cutting roller motor 12, a left fixed roller motor 13, a right fixed roller motor 14, and a floating roller motor 15. The first cutting roller motor 11, the second cutting roller motor 12, the left fixed roller motor 13, the right fixed roller motor 14, and the floating roller motor 15 respectively drive the first cutting roller 32, the second cutting roller 33, the fixed roller 34, and the floating roller 35 to perform rotational motion. The two motors drive the two cutting rollers to rotate and cut the sugarcane, resulting in a better cutting effect. Since the fixed roller is located below, it plays the role of supporting and biting the sugarcane for transmission. Therefore, the fixed roller 34 is driven to rotate by the two motors, the left fixed roller motor 13 and the right fixed roller motor 14. The floating roller 35 needs to float up and down, so it is driven to rotate by one motor. This ensures that the sugarcane can be bitten and transmitted while avoiding excessive weight and lower cost.

[0032] Specifically, port A of the first reversing valve 6 is connected to the first cutting roller motor 11 via the first branch 16. The first cutting roller motor 11 is connected to the fixed roller left motor 13 and the fixed roller right motor 14 via two parallel oil lines. The fixed roller left motor 13 is connected to the floating roller motor 15. The fixed roller right motor 14 and the floating roller motor 15 are both connected to port B of the first reversing valve 6. Port A of the first reversing valve 6 is also connected to the second cutting roller motor 12 via the second branch 17. The second cutting roller motor 12 is connected to the feeding elevator motor 1, and the feeding elevator motor 1 is connected to port B of the first reversing valve 6. This allows oil to be supplied to the first cutting roller motor 11, the second cutting roller motor 12, the fixed roller left motor 13, the fixed roller right motor 14, and the floating roller motor 15 via the first reversing valve 6. At the same time, the layout of the hydraulic circuit is reasonably optimized, making the circuit easy to control, and the cost is relatively low.

[0033] Preferably, in this embodiment, the integrated material loading ladder f is a scraper conveyor chain, and the integrated material loading ladder motor 4 is a single drive. The B port of the second reversing valve 7, the integrated material loading ladder motor 4, and the A port of the second reversing valve 7 are connected in sequence. Their series connection can ensure that the speed of the integrated material loading ladder f is consistent, making the sugarcane transportation smoother and the cost lower.

[0034] Preferably, the actuator includes a first hydraulic pump 18, a second hydraulic pump 19, and a transfer case 20. The input end of the transfer case 20 is connected to the output end of the transmission system. The power input ends of the first hydraulic pump 18 and the second hydraulic pump 19 are both connected to the output end of the transfer case 20. The P ports of the first directional valve 6 and the second directional valve 7 are both connected to the output end of the first hydraulic pump 18. The P port of the third directional valve 8 is connected to the output end of the second hydraulic pump 19. The liquid input ends of the first hydraulic pump 18 and the second hydraulic pump 19 are both connected to the hydraulic oil tank 5, thereby realizing the drawing of hydraulic oil into the first directional valve 6, the second directional valve 7, and the third directional valve 8.

[0035] Preferred, such as Figure 2 As shown, the transmission system of this embodiment includes an input shaft 22, which is rotatably mounted on the frame assembly a. One end of the input shaft 22 is connected to the input end of the transfer case 20, and the other end is detachably connected to the output end of the tractor, engine, or drive motor, thereby transmitting power to the transfer case 20. The detachable connection between the input shaft 22 and the tractor, engine, or drive motor facilitates the replacement of different power sources, making it more convenient to use. This transmission system structure allows the transfer case 20 to be mounted horizontally on the frame assembly a. The transfer case 20 can be designed with horizontally parallel connection ports, with the first hydraulic pump 18 and the second hydraulic pump 19 connected to its left side, and the input shaft 22 connected to its right side.

[0036] like Figure 5As shown, in another embodiment, the transmission system includes a connecting shaft 9 and a drive shaft 10. The connecting shaft 9 is rotatably mounted on the frame assembly a via a bearing housing. One end of the drive shaft 10 is hinged to the input end of the transfer case 20, and the other end is hinged to one end of the connecting shaft 9. The other end of the connecting shaft 9 is detachably connected to the output end of the tractor, engine, or drive motor. This transmission system structure allows the transfer case 20 to be mounted vertically on the frame assembly a. The transfer case 20 can be designed with a two-layer connection structure. The lower right end can be reserved for a power output port, such as for connecting a generator, while the upper left and right ends connect to the first hydraulic pump 18 and the second hydraulic pump 19. This reduces the use of couplings, resulting in a more compact structure and improved space utilization. The power source drives the connecting shaft 9 to rotate, which in turn drives the drive shaft 10 to rotate, which in turn drives the transfer case 20 to rotate. Finally, the transfer case 20 provides power torque to the first hydraulic pump 18 and the second hydraulic pump 19. The transmission system with this structure has low loss, and all components that transmit torque can be made of metal. Compared with the transmission system structure mentioned above, it can avoid the problem of rubber coupling loss, significantly improve transmission reliability, and thus extend service life.

[0037] Preferably, an oil diffuser 30 and an oil filter 31 are provided between the T-port of the first directional valve 6, the second directional valve 7 and the third directional valve 8 and the hydraulic oil tank 5. The oil diffuser 30 is a hydraulic oil cooler used to cool the hydraulic oil, and the oil filter 31 is a hydraulic oil filter used to filter the hydraulic oil.

[0038] Preferred, such as Figure 1 As shown, the hydraulic power system of this utility model also includes a feeding ladder angle cylinder 25 and a material leveling and loading integrated ladder cylinder 26. The feeding ladder angle cylinder 25 is used to unfold the feeding ladder b, allowing the feeding ladder to be stored or unfolded for use. The material leveling and loading integrated ladder cylinder 26 is used to adjust the tilt angle of the material leveling and loading integrated ladder f. Both the feeding ladder angle cylinder 25 and the material leveling and loading integrated ladder cylinder 26 are detachably connected to the tractor hydraulic system 27. The feeding ladder angle cylinder 25 and the material leveling and loading integrated ladder cylinder 26 are divided into two hydraulic drive systems with the feeding ladder motor 1, the cutting device motor, the impurity removal device motor 3, and the material leveling and loading integrated ladder motor 4. Through clever layout, the hydraulic system carried by the tractor itself can be utilized, eliminating the need for additional hydraulic pipelines and effectively reducing costs. In actual use, after the entire sugarcane cleaning equipment is moved to the designated location by a tractor, the feeding ladder b can be unfolded and used immediately using the hydraulic system carried by the tractor. At the same time, the angle of the material leveling and loading integrated ladder f can be adjusted to quickly unfold and stabilize the sugarcane cleaning equipment. Then, the power source issues of the feeding ladder motor 1, the cutting device motor, the cleaning device motor 3, and the material leveling and loading integrated ladder motor 4 can be considered, making it more convenient to use.

[0039] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these will not affect the implementation effect of this utility model or the practicality of the patent.
