Internal combustion engine power self-propelled lotus root picking machine adopting compressed air injection and suction type spraying head

Abstract

The invention provides an internal combustion engine power self-propelled lotus root picking machine adopting a compressed air injection and suction type spraying head. According to the technical scheme, the internal combustion engine power self-propelled lotus root picking machine is mainly composed of water spraying frame shoe plates (1), the injection and suction type spraying head (2), an air conveying pipe (3), an air dividing cylinder (4), a main air conveying pipe (5), an air compressor (6), an air compressor coupler (7), an internal combustion engine (8), a speed reducer (9), a gearbox (10), a differential mechanism (11), a triangular belt drive device (12), walking wheels (13), a keel (14), a case (15), a spraying head lifting device (16), a spraying head rack (17), a treading face (18), spokes (19), a water stirring plate (20), connecting devices (21), hubs (22), rubber wheel gear racks (23), an air pipe connector (24), a fixed plate (25), water inlet holes (26), a water-gas mixing chamber (27) and a filter screen (28). The internal combustion engine power self-propelled lotus root picking machine has the advantages of being reasonable and practical in design, high in work efficiency, more attractive in product and suitable for wide application and popularization, saving time and labor, increasing the yield and improving quality.

Description

technical field [0001] The invention relates to the technical field of lotus root picking machines, in particular to a self-propelled lotus root picking machine powered by an internal combustion engine using a compressed air injection nozzle. Background technique [0002] There is no mature technology for lotus root harvesting machines in foreign countries. Some domestic enterprises and research institutes have researched and produced some types of lotus root harvesters. There are two main types, one is human-driven, which uses a small-power internal combustion engine to drive a centrifugal water pump, and uses a hydraulic nozzle as the power to pick lotus root to wash away the silt around the root of the lotus root, make the lotus root float out of the water, and pick it up manually. The movement of the machine in the lotus field is driven by manpower. The second kind of lotus root harvesting machine is arranged on a body similar to a ship hull, powered by an internal comb...

AI Technical Summary

Problems solved by technology

[0003] Some lotus root harvesting machines in China have the following disadvantages: 1. Small manpower-driven lotus root harvesting machines have low efficiency and are only suitable for use in smaller ponds

2. The self-propelled lotus root picking machine mostly uses ready-made car and tractor tires as walking parts, which is not suitable for the muddy ground in the water of the lotus root field, let alone the steep slope across the ridge of the paddy field

3. The water pump works in the muddy water of the lotus root field, and the water inlet faucet is easily blocked by weeds and sludge, which affects the normal operation of the water pump and needs to be shut down frequently for cleaning

4. The water pump works in muddy water, and there is a lot of sediment in the water, which is easy to wear the pump impeller, mouth ring and other parts, reducing the service life of the pump
