High-clearance crawler-type inter-line tea picker based on hybrid power

Abstract

The invention relates to a high-clearance crawler-type inter-line tea picker based on hybrid power, which comprises a walking power mechanism, a lifting mechanism and a tea picking assembly, wherein the tea picking assembly comprises an auxiliary frame, a cutter and an induction unit which automatically senses the depth of tea picking by the cutter; the cutter and the induction unit are installedon the auxiliary frame; the induction unit comprises an induction board, an upward travel switch, a downward travel switch and a travel switch contact mounted on the induction board; the induction board covers a tea tree; when the travel switch contact is contacted with the downward travel switch, the lifting mechanism controls the tea picking assembly to descend on a whole until the induction board is lifted up by the tea tree and the travel switch contact is separated from the downward travel switch; and when the induction board is lifted up by the tea tree until the travel switch contact iscontacted with the upward travel switch, the lifting mechanism controls the tea picking assembly to rise on the whole until the travel switch contact is separated from the upward travel switch. The sizes of fresh leaves picked by the cutter are ensured to be uniform and the quality of tea is ensured.

Description

technical field [0001] The invention belongs to the field of tea-picking machinery and equipment, and in particular relates to a high-gap crawler-type inter-row tea-picking machine based on hybrid power. Background technique [0002] At present, single-person tea picking machines and double-person tea picking machines are mostly backpack-type, which cause high noise during work, high labor intensity and low efficiency. There is also a row-to-row self-propelled motorized tea picking machine, and its lower chassis design is easily lifted when there are larger stones below the chassis so that the driving wheel (track) is suspended, and the passability is poor. The noise and pollution of the gasoline engine-powered tea picking machine is relatively large, and the tea leaves are easily absorbed by the exhaust gas emitted by the gasoline engine, which affects the quality of the fresh leaves picked by the machine; for the pure electric tea picking machine, due to the limitation of ...

AI Technical Summary

Problems solved by technology

[0002] At present, single-person tea picking machines and double-person tea picking machines are mostly backpack-type, which cause loud noise during work, high labor intensity and low efficiency.

There are also inter-row self-propelled motorized tea picking machines, which are designed with a low chassis. When there are large stones under the chassis, they are easy to be jacked up, so that the driving wheels (tracks) are suspended in the air, and the passability is poor.

The noise and pollution of the gasoline engine-powered tea picking machine is relatively large, and the tea leaves are easily absorbed by the exhaust gas emitted by the gasoline engine, which affects the quality of the fresh leaves picked by the machine; for the pure electric tea picking machine, due to the limitation of the battery capacity, the continuous operation is generally less than 4 hours, and the field is not stable. Unable to charge, affecting actual use and promotion

At present, the height of the cutter of the tea picking machine is controlled manually, and it is impossible to accurately control the cutting depth of the cutter, and the picked fresh leaves are of different sizes, which affects the quality of picking
