Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a tracked ginger harvester. Background Technology

[0002] In traditional agricultural planting, ginger, as an underground tuber-based economic crop, has long relied on a purely manual harvesting method. When ginger reaches maturity, growers need to first dig up the topsoil with tools such as hoes, then manually pull out and shake off the attached soil, and finally use knives to separate the stems and leaves. This method of operation has certain technical defects.

[0003] Prior art document CN 210298552U discloses an automatic ginger harvester, including a main frame with an engine, transmission system, walking system, and direction control system mounted on it. A soil-loosening frame and a ginger-pulling frame are hinged to the main frame. A soil-loosening frame lifting device is hinged between the main frame and the soil-loosening frame, and a ginger-pulling frame lifting device is hinged between the main frame and the ginger-pulling frame. The prior art document depicts a hand-held tracked tractor. In this technical solution, the operator stands behind the automatic ginger harvester and controls the machine through the direction control system. The operator follows the machine's movement with their feet, often tripping over the roots and stems on the ground, causing machine malfunction and personal injury. The operator's working environment is harsh and the labor intensity is high.

[0004] The comparative document also states that the main frame 1 can also be used as a mounting device, mounted on tractors or other traction equipment, or other suitable power equipment can be used as the traction machinery. However, adopting this structure will increase the overall length of the ginger harvester and the tractor, making operation and control more difficult. It will also significantly increase the machine's turning radius, prolong harvesting time, and reduce work efficiency. Utility Model Content

[0196] This utility model of a tracked ginger harvester is easy to operate. The operator sits on the harvester, reducing the difficulty and labor intensity of operation. Its compact structure allows for a turning radius of 1 to 1.5 meters, improving work efficiency.

[0197] This utility model of a tracked ginger harvester consists of a sprocket, a drag chain, and guide wheels in its walking mechanism. The sprocket teeth mesh with the rectangular grooves on the inner side of the drag chain to transmit torque. The outer transverse support plate of the drag chain contacts the soil to generate traction. The longitudinal guide plate guides the sprocket to prevent axial displacement of the sprocket. At the same time, the longitudinal guide plate is embedded in the guide wheel to form a double guiding constraint, thereby stabilizing the walking trajectory in the field, preventing the ginger harvester from sinking into the soil, reducing the bumps of the ginger harvester, and improving the safety and comfort of the operator.

[0198] This utility model of a tracked ginger harvester features an engine that drives a gearbox via belt transmission, and a differential distributes power to the output shafts on both sides to drive the sprockets to rotate. A hydraulic brake disc applies single-sided braking to the output shafts, achieving flexible power distribution and precise steering. The engine synchronously drives a generator to generate electricity, which is stored in a battery to power the control system and hydraulic valve group. A plunger pump converts mechanical energy into hydraulic energy to drive the hydraulic cylinders, enabling continuous operation without external power and hydraulic lifting of the ginger harvesting device.

[0199] This utility model relates to a tracked ginger harvester. A hydraulic cylinder extends and retracts to move the ginger harvesting device up and down, enabling electric adjustment of the device's height. The ginger harvester bracket is housed within a guide groove on a guide frame. The bracket is bolted to the ginger harvester fixing frame, allowing for manual adjustment of the device's height. The manual and electric height adjustments work together; in the event of a hydraulic system malfunction, manual adjustment of the ginger harvester's height ensures precise position control.

[0200] This utility model of a tracked ginger harvester features a frame constructed from welded I-beams to form a rigid support structure. Combined with bottom guide wheels and side sprockets, it forms a three-point support plane, enhancing the machine's load-bearing capacity and structural stability. A hydraulic oil tank located behind the seat facilitates oil level monitoring and maintenance. A generator and battery form a self-powered system, ensuring convenient maintenance and energy independence. Finally, a centralized engine drive enables coordinated operation of walking, braking, lifting, and power generation functions, achieving efficient and stable ginger harvesting operations.

[0201] When this tracked ginger harvester is in operation, the engine 7 transmits power to the gearbox 6 via belt drive. The differential in the gearbox 6 distributes power to the output shafts 803 on both sides, driving the sprocket 3 to rotate. The sprocket 3 drives the drag chain 401 to rotate. When the brake lever 10 is operated, the brake fluid pressure causes the brake disc friction pads to clamp the brake disc, realizing braking of the walking mechanism. When turning, a speed difference is formed by braking on one side, which, together with the differential power distribution, enables flexible steering and U-turns. The braking response time is short and the braking force is adjustable. The engine 7 synchronously drives the generator to generate electricity and store it in the battery, which powers the control system and hydraulic valve group. The plunger pump 12 converts mechanical energy into hydraulic energy to drive the hydraulic cylinder 13. The hydraulic cylinder 13 extends and retracts, driving the ginger harvesting device 11 to rise and fall. The hydraulic oil tank 15 supplies oil to the entire hydraulic system. The height of the ginger harvesting device is infinitely adjustable by extending and retracting the hydraulic cylinder. The two ends of the hydraulic cylinder are hinged to the first support and the ginger harvesting device, respectively. The hydraulic valve group controls the oil circuit opening and closing and the flow rate, realizing precise control of the lifting speed and position. The machine is driven by a central engine to achieve coordinated operation of walking, braking, lifting and power generation functions to complete the ginger harvesting operation.
