Description

Technical Field

[0001] This utility model relates to the field of agricultural harvesting machinery technology, specifically to a hydraulic drive device for lifting and transporting corn ears. Background Technology

[0002] Corn harvesting machinery uses a header to separate the ears from the plant and transport them to an ear conveyor. A chain rake elevator then pushes the ears to a husk-removing mechanism, where the husks are removed and the ears are thrown into the grain bin, completing the harvesting process. Conventional header ear picking, the chain rake elevator, and the suction fan on the elevator all rely on mechanical transmission. A belt or chain transmits the engine power to the drive shaft of the header and elevator, which then transmits the power to the drive shaft of the suction fan transmission box. The suction fan is mounted on the output shaft of the suction fan transmission box. Due to the complexity of the mechanical transmission structure, the long transmission route, and the difficulty of adjustment, the mechanical structure has a high failure rate, and adjustments and maintenance are time-consuming and labor-intensive.

Detailed Implementation

[0016] Example: Figures 1 to 3 As shown, a hydraulic drive device for lifting and transporting corn ears includes a hydraulic oil tank 1, a hydraulic control component 2 connected to the hydraulic oil tank 1, and a traveling pump 4 connected to the hydraulic oil tank 1. Two traveling pumps 4 are provided; one is connected to a lifting hydraulic drive component 5 via an oil pipe, and the other is connected to a header hydraulic drive component 7 via an oil pipe. A lifting fan hydraulic drive component 8 is connected to the hydraulic oil tank 1. The input end of the hydraulic oil tank 1 is connected to the output end of a cooler 3, and the input end of the cooler 3 is connected to the lifting hydraulic drive component 5, the header hydraulic drive component 7, and the lifting fan hydraulic drive component 8, respectively. Because the hydraulic system generates a large amount of heat and the hydraulic oil temperature is high during operation, a cooler 3 needs to be connected in series in the pipeline to remove most of the heat. The hydraulic power source is the traveling pump 4, which is a double gear pump connected to the traveling pump.

[0017] The lifting hydraulic drive assembly 5 includes a lifting motor control valve 51. The input end of the lifting motor control valve 51 is connected to the travel pump 4 via an oil pipe. The A end of the lifting motor control valve 51 is connected to the B end of the BM series lifting cycloidal motor 52. The B end of the lifting motor control valve 51 is connected to one end of the lifting speed control valve 53. The other end of the lifting speed control valve 53 is connected to the A end of the BM series lifting cycloidal motor 52. The output end of the lifting motor control valve 51 is connected to the cooler 3 via an oil pipe.

[0018] The elevator operates via a BM series cycloidal elevator motor 52, with direction control achieved electrically by the elevator motor control valve 51. When coil a of the elevator motor control valve 51 is energized, the BM series cycloidal elevator motor 52 rotates forward, allowing the elevator to feed material normally. When coil b of the elevator motor control valve 51 is energized, the BM series cycloidal elevator motor 52 reverses, causing the elevator to discharge material and clear blockages. Motor speed adjustment is achieved through flow control via the elevator speed regulating valve 53.

[0019] The BM series lifting cycloidal motor 52 is connected to a lifting assembly 6, which includes a lifting frame 61. A fixed adjustment frame 66 is connected to one side of the lifting frame 61, and a motor fixing frame 65 is connected to the fixed adjustment frame 66. The motor fixing frame 65 is slidably connected to the lifting frame 61 and fixedly connected to the BM series lifting cycloidal motor 52. A coupling 62 is connected to the rotation output end of the BM series lifting cycloidal motor 52. One end of a drive lifting rod 63 is connected to the coupling 62, and the other end of the drive lifting rod 63 is rotatably connected to the lifting frame 61. A driven lifting rod 64 is rotatably connected to the lifting frame 61, and the drive lifting rod 63 is driven by the driven lifting rod 64 via a conveyor belt.

[0020] The BM series cycloidal lifting motor 52 transmits power to the coupling 62, which in turn drives the lifting rod 63. The lifting rod 63, which is connected to a gear, drives the conveyor belt. The conveyor belt has a chain that meshes with the gear, thus enabling the lifting rod 63 to drive the driven lifting rod 64, thereby achieving the upward transport of corn.

[0021] The hydraulic control assembly 2 includes an engine pump 21, one end of which is connected to the hydraulic oil tank 1, and the other end of which is connected to a control multi-way valve 22. The control multi-way valve 22 is connected to a main clutch cylinder 23.

[0022] The engine pump 21, mounted on the engine, provides power to the hydraulic control circuit and pressurizes the control multi-way valve 22. When the main clutch engagement button is pressed, the coil b1 of the main clutch disc valve of the control multi-way valve 22 is energized, the A1 port oil circuit is connected, oil enters the main clutch cylinder 23, the main clutch tensioning mechanism is activated, and the main clutch engages and begins to work. Through electrical control, when the main clutch engagement button is pressed and the coil b1 of the main clutch disc valve of the control multi-way valve 22 is energized, the coil a of the header motor control valve 71, the coil a of the hoisting motor control valve 51, and the coil of the hoisting blower hydraulic unloading valve 87 are energized. The BM series header cycloidal motor 72, the BM series hoisting cycloidal motor 52, the BM series front cycloidal motor 83, and the BM series rear cycloidal motor 84 begin to rotate to achieve normal harvesting operations.

[0023] The hydraulic drive assembly 7 for the header includes a header motor control valve 71. The input end of the header motor control valve 71 is connected to the travel pump 4 via an oil pipe. The A end of the header motor control valve 71 is connected to the B end of the BM series header cycloidal motor 72. The B end of the header motor control valve 71 is connected to one end of the header speed control valve 73. The other end of the header speed control valve 73 is connected to the A end of the BM series header cycloidal motor 72. The output end of the header motor control valve 71 is connected to the cooler 3 via an oil pipe.

[0024] The header's operation is achieved by the BM series header cycloidal motor 72, and direction control is electrically controlled by the header motor control valve 71. When coil a of the header motor control valve 71 is energized, the BM series header cycloidal motor 72 rotates forward, and the header normally picks and feeds ears; when coil b of the header motor control valve 71 is energized, the BM series header cycloidal motor 72 reverses, realizing the backflow of material from the header and clearing blockages. The motor speed is adjusted through the flow control of the header speed regulating valve 73.

[0025] The hydraulic drive assembly 8 for the lifting fan includes a lifting gear pump 81, which is connected to the hydraulic oil tank 1. The output end of the lifting gear pump 81 is connected to a fan speed control valve 82, a lifting fan overflow valve 86, and a lifting fan unloading valve 87. The output end of the fan speed control valve 82 is connected to the A end of a BM series front cycloidal motor 83. The B end of the BM series front cycloidal motor 83 is connected to the A end of a BM series rear cycloidal motor 84 and a safety valve 85. The B end of the BM series rear cycloidal motor 84, the safety valve 85, the lifting fan overflow valve 86, and the lifting fan unloading valve 87 are all connected to the cooler 3 via oil pipes.

[0026] The lifting gear pump 81 utilizes a power output pulley for belt drive, powered by the BM series front cycloidal motor 83 and the BM series rear cycloidal motor 84. When the lifting fan is running, the lifting fan unloading valve 87 is a normally open solenoid valve. Before the coil is energized, the circulating hydraulic oil of the lifting gear pump 81 returns to the hydraulic oil tank 1 through the lifting fan unloading valve 87, and the system pressure of the lifting fan relief valve 86 is the return oil pressure. When the lifting fan unloading valve 87 is energized, it closes, and the circulating hydraulic oil of the lifting gear pump 81 establishes system pressure P1 through the lifting fan relief valve 86, providing power to the lifting fan hydraulic system. The maximum pressure at the inlet A port of the BM series front cycloidal motor 83 is the pressure set by the lifting fan relief valve 86, and the maximum pressure at the outlet B port is the pressure set by the safety valve 85. The oil outlet (Port B) of the BM series front cycloidal motor 83 and the oil inlet (Port A) of the BM series rear cycloidal motor 84 are connected, forming a hydraulic series circuit. The fan speed in the series circuit is controlled by adjusting the flow rate of the fan speed control valve 82. When the system pressure P1 exceeds the set pressure of the lifting fan overflow valve 7 or the local pressure P2 exceeds the set pressure of the safety valve 10 due to blockage, the lifting fan overflow valve 7 or the safety valve 10 will open for overflow protection, ensuring that the lifting fan gear pump 1 or the BM series front cycloidal motor 9 will not be damaged due to overpressure.
