Novel driving system for transplanter

Abstract

The invention discloses a novel driving system for a transplanter which comprises a frame, and an engine, a power generator assembly, a control system, a storage battery, a gear box and a driven shaft travel section are arranged on the frame; the gear box comprises an on-off transplanting power control part, an external gear for deceleration, a symmetric planetary gear for deceleration and a gear worm for speed control. The gear worm is electrically controlled and can regulate the rotary speed of travel wheels at two ends respectively, therefore, the stepless-change forward gear, reverse gear and neutral gear can be output when rotating at a uniform speed, differential accurate steering and in-situ turning over in the field can be realized when rotating at a non-uniform speed or rotating reversely, and the forward gear with nonadjustable speed can be realized when not rotating. The novel driving system for the transplanter is simple in structure and machining, integrates electrical regulation of speed, electrically-controlled differential steering and in-situ turning over, is particularly suitable for line control, on line and remote control transplanters, greatly improves working quality, lowers labor intensity and is the development trend of future transplanter driving systems.

Description

technical field [0001] The invention relates to the field of agricultural machinery drive systems, in particular to a novel rice transplanter drive system. Background technique [0002] At present, motorized rice transplanters are classified according to the operation mode, and are divided into ride-on and hand-held self-propelled rice transplanters. Among them, ride-on rice transplanters are mainly imported and foreign-funded enterprise products, with high technological content, reliable quality, convenient operation and adjustment, low labor intensity, and high operating efficiency, but they are expensive and have a long investment recovery period; The drive slips when working in the mud field after being driven by a human. Usually, four-wheel drive is used, with heavy weight and complex structure, which is difficult to adapt to the working environment in mountainous areas and small fields. The hand-held self-propelled rice transplanter has simple structure, reliable perf...

Problems solved by technology

However, the hand-held self-propelled rice transplanter requires the driver to hold the handrail of the rice transplanter and follow the rice transplanter to walk in the mud field, which is labor-intensive and low-efficiency.

The drive system of the current walk-behind self-propelled rice transplanter not only provides the power for the transplanter to transplant the rice seedlings, but also provides the driving force of the rice transplanter. The clutch mechanism adopts the sliding gear to shift gears. During the use process, the whole process needs to be driven manually. Since people walk behind the rice transplanter, they should not only drive the rice transplanter, but also pay attention not to step on the transplanted rice seedlings. Low, high labor intensity, low quality of rice transplanting

Especially when turning or making a U-turn in the field, the transplanter needs to manually change gears and reverse, which can easily cause uneven transplanting of seedlings, a large U-turn area in the field, and many footprints at the U-turn, which affects the quality of planting.
