Detailed Implementation

[0031] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0032] See Figure 1 As shown, the sugarcane cleaning equipment used in the electric power system of this utility model includes a feeding ladder b, a cutting device c, a leveling ladder d, a cleaning device e, and a loading ladder f. The feeding ladder b, the cutting device c, the leveling ladder d, the cleaning device e, and the loading ladder f are all integrated on the frame assembly a.

[0033] See Figure 2-3 As shown, this utility model discloses an electric power system for a sugarcane impurity removal device, including a feeding ladder motor, a cutting device motor, a leveling ladder motor, an impurity removal device motor 1, and a loading ladder motor. The feeding ladder motor, cutting device motor, leveling ladder motor, impurity removal device motor 1, and loading ladder motor are all hydraulic motors. These motors respectively drive the feeding ladder b, cutting device c, leveling ladder d, impurity removal device e, and loading ladder f to perform their respective movements. The fully hydraulic drive provides better driving stability. The electric power system also includes a hydraulic oil tank 2, a drive motor 3, and a dual pump 4. The dual pump 4 has three interfaces: a liquid input end, a power input end, and an output end. The liquid input end of the dual pump 4 is connected to the hydraulic oil tank 2. The output end of the dual pump 4 is connected to the feeding ladder motor, the cutting device motor, the equalizing ladder motor, the impurity removal device motor 1, and the loading ladder motor through a hydraulic oil distributor. The output end of the drive motor 3 is connected to the power input end of the dual pump 4.

[0034] The electric power system of this utility model uses a drive motor 3 as a power source to drive the entire machine. When the drive motor 3 starts, it drives the double pump 4 to rotate. The double pump 4 draws hydraulic oil from the hydraulic oil tank 2, and the hydraulic flow and direction are further regulated by a specially designed hydraulic oil distributor. This activates the feeding ladder motor, cutting device motor, material leveling ladder motor, impurity removal device motor, and loading ladder motor to perform their movements, ensuring the smooth operation of the entire hydraulic system. Compared with traditional engine or tractor drive solutions, the electric motor not only has lower energy consumption and simpler maintenance, but also reduces the transmission system between the engine or tractor and the double pump. The structural layout is more reasonable, the entire equipment is more compact, and the cost is lower. Moreover, it can maintain high efficiency and stability during long-term operation, while reducing fuel consumption and emissions. This aligns with the trend of energy conservation and emission reduction, achieves the goal of environmentally friendly production, and meets the high environmental standards required by modern agricultural machinery.

[0035] Preferably, the hydraulic oil distributor includes a three-position four-way directional valve 5 and a two-position four-way directional valve 6. Both the three-position four-way directional valve 5 and the two-position four-way directional valve 6 are existing directional valves with four ports: A, B, P, and T. Ports A and B of the three-position four-way directional valve 5 are connected to the feeding elevator motor and the cutting device motor, respectively; port P of the three-position four-way directional valve 5 is connected to the hydraulic oil tank 2; and port T of the three-position four-way directional valve 5 is connected to the output end of the double pump 4. Ports A and B of the two-position four-way directional valve 6 are connected to the loading elevator motor, the material leveling elevator motor, and the impurity removal device motor 1, respectively; port P of the two-position four-way directional valve 6 is connected to the hydraulic oil tank 2; and port T of the two-position four-way directional valve 6 is connected to the output end of the double pump 4. This allows for the supply of oil to the feeding elevator motor, the cutting device motor, the material leveling elevator motor, the impurity removal device motor 1, and the loading elevator motor through the two directional valves, resulting in a relatively lower cost.

[0036] Preferably, a relief valve 7 is provided between the P port and the T port of both the three-position four-way directional valve 5 and the two-position four-way directional valve 6 to prevent excessive oil pressure in the two directional valves. A replenishing valve 8 is provided between the A port, B port and P port of the three-position four-way directional valve 5, which can replenish hydraulic oil and ensure stable oil pressure in the hydraulic system.

[0037] Preferably, the B port of the two-position four-way reversing valve 6, the loading ladder motor, the material leveling ladder motor, the impurity removal device motor 1, and the A port of the two-position four-way reversing valve 6 are connected in series. This series connection ensures that the loading ladder f and the material leveling ladder d have consistent speeds, making the sugarcane conveying smoother and allowing the impurity removal device to maintain a stable rotation speed, which helps to ensure continuous impurity removal. Furthermore, in this embodiment, both the loading ladder f and the material leveling ladder d are conveyor belts, and there are two motors for both the loading ladder and the material leveling ladder, which is a dual-drive configuration. Specifically, the loading ladder motor includes a first loading roller motor 9 and a second loading roller motor 10, and the material leveling ladder motor includes a first material leveling roller motor 11 and a second material leveling roller motor 12; wherein, the B port of the two-position four-way reversing valve 6 is connected to the impurity removal device motor 1; the impurity removal device motor 1 is connected to the first material leveling roller motor 11 through the third branch 13, the first material leveling roller motor 11 is connected to the first loading roller motor 9, and the first loading roller motor 9 is connected to the A port of the two-position four-way reversing valve 6; the impurity removal device motor 1 is also connected to the second material leveling roller motor 12 through the fourth branch 14, the second material leveling roller motor 12 is connected to the second loading roller motor 10, and the second loading roller motor 10 is connected to the A port of the two-position four-way reversing valve 6. A two-position four-way directional valve 6 supplies oil to the first loading roller motor 9, the second loading roller motor 10, the first leveling roller motor 11, the second leveling roller motor 12, and the impurity removal device motor 1, respectively. This optimizes the layout of the hydraulic circuit, facilitates circuit control, and results in relatively low cost. In this embodiment, both the loading ladder f and the leveling ladder d are driven by dual motors, resulting in better conveying stability.

[0038] 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 15, a second cutting roller motor 16, a left fixed roller motor 17, a right fixed roller motor 18, and a floating roller motor 19. The first cutting roller motor 15, the second cutting roller motor 16, the left fixed roller motor 17, the right fixed roller motor 18, and the floating roller motor 19 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 cutting rollers are driven 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 during transmission. Therefore, the fixed roller 34 is driven to rotate by two motors: the fixed roller left motor 17 and the fixed roller right motor 18. 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 cost. The feeding ladder motor includes a first feeding roller motor 20 and a second feeding roller motor 21. The feeding ladder b driven by the dual motors has better conveying stability.

[0039] Specifically, the A port of the three-position four-way reversing valve 5 is connected to the first cutting roller motor 15 through the first branch 22. The first cutting roller motor 15 is connected to the fixed roller left motor 17 and the fixed roller right motor 18 through two parallel oil lines respectively. The fixed roller left motor 17 is connected to the floating roller motor 19. The fixed roller right motor 18 and the floating roller motor 19 are both connected to the B port of the three-position four-way reversing valve 5. The A port of the three-position four-way reversing valve 5 is also connected to the second cutting roller motor 16 through the second branch 23. The second cutting roller motor 16 is connected to the first feeding roller motor 20 and the second feeding roller motor 21 through two parallel oil lines respectively. The first feeding roller motor 20 and the second feeding roller motor 21 are both connected to the B port of the three-position four-way reversing valve 5. The system enables oil supply to the first cutting roller motor 15, the second cutting roller motor 16, the left fixed roller motor 17, the right fixed roller motor 18, and the floating roller motor 19 via a three-position four-way directional valve 5. At the same time, the layout of the hydraulic circuit is reasonably optimized, making the circuit easy to control and relatively low in cost.

[0040] Preferably, an oil cooler 24 and an oil filter 25 are respectively provided between the P port of the three-position four-way directional valve 5 and the two-position four-way directional valve 6 and the hydraulic oil tank 2. The oil cooler 24 is a hydraulic oil cooler used to cool the hydraulic oil, and the oil filter 25 is a hydraulic oil filter used to filter the hydraulic oil.

[0041] Preferably, the drive motor 3 is integrated into the frame of the sugarcane cleaning equipment, that is, the drive motor 3 is mounted on the frame assembly a, and can be transported and moved with the frame assembly a, making it more convenient to use. In particular, a motor protective cover is provided around the drive motor 3 to protect it.

[0042] Preferred, such as Figure 1As shown, the hydraulic power system of this utility model also includes a feeding ladder folding cylinder 26, a feeding ladder angle cylinder 27, and a loading ladder cylinder 28. The feeding ladder folding cylinder 26 is used to fold multiple sections of the feeding ladder b together, and the feeding ladder angle cylinder 27 is used to fold or unfold the feeding ladder b. The feeding ladder folding cylinder 26 and the feeding ladder angle cylinder 27 work together to fold and store or unfold the feeding ladder for use. The loading ladder cylinder 28 is used to adjust the tilt angle of the loading ladder f. The feeding ladder folding cylinder 26, the feeding ladder angle cylinder 27, and the loading ladder cylinder 28 are all detachably connected to the tractor hydraulic system 29. The three cylinders, along with the feeding ladder motor, the cutting device motor, the material leveling ladder motor, the impurity removal device motor, and the loading ladder motor, are divided into two sets of hydraulic drive systems. 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 moving the entire sugarcane cleaning equipment to the designated location using a tractor, the feeding ladder b can be deployed immediately using the hydraulic system carried by the tractor. At the same time, the angle of the loading ladder f can be adjusted to quickly and stably deploy the sugarcane cleaning equipment. Then, the issues of the feeding ladder motor, cutting device motor, equalizing ladder motor, cleaning device motor, and loading ladder motor can be considered, making it more convenient to use.

[0043] Preferably, a throttle valve 30 is provided on the oil inlet pipes corresponding to the feeding ladder folding cylinder 26, the feeding ladder angle cylinder 27, and the loading ladder cylinder 28 to control the hydraulic oil flow. A balance valve 31 is also provided between the loading ladder cylinder 28 and the tractor hydraulic system 29 to adjust the pressure balance on both sides of the loading ladder cylinder 28, so that the loading ladder cylinder 28 is in a stable state, ensuring the stability of the sugarcane conveying height and improving the safety of use.

[0044] 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.
