Suspension type water chestnut digging machine

Abstract

The invention discloses a suspension type water chestnut digging machine which comprises a machine frame, two sets of depth limiting wheels, a lifting chain component, a rubber tooth roller, a positive and negative spiral spring shaft and two sets of land wheels. The digging shovel is driven to advance, the digging shovel is driven by the eccentric wheel to vibrate to shovel upturned soil, the upturned soil is subsequently shaken by the lifting chain component to be split into soil blocks, and then the soil blocks fall onto a spring screen surface formed by alternately arranging positive and negative spiral spring shafts after being hit and extruded by the rubber tooth roller to be crushed; large soil blocks fall on the surface of the spring screen and then are beaten and extruded by the two rubber tooth rollers to be further crushed, meanwhile, the positive and negative spiral spring shafts synchronously rotate backwards to rub a mixture of the soil blocks and the water chestnuts and drive the mixture of the water chestnuts and the soil to rotate, and the soil adhering to the water chestnuts is further removed; soil blocks fall on the ground through gaps between the positive and negative spiral spring shafts and gaps of the springs, and large soil blocks and water chestnuts are conveyed to the rear end of the machine through a rolling screen face composed of the positive and negative spiral spring shafts and laid on the ground.

Description

technical field [0001] The invention relates to the related technical field of water chestnut digging equipment, in particular to a suspended water chestnut digging machine. Background technique [0002] At present, water chestnuts are widely planted and can be used as fruits and vegetables with good economic value. At present, the harvest of water chestnuts mainly depends on manual excavation, the degree of mechanization is low, and the production efficiency cannot meet the raw material demand for daily sales and deep processing. At the same time, labor costs are increasing day by day, which seriously restricts the sustainable development of the water chestnut industry. [0003] When mechanized harvesting water chestnuts, the planting environment of water chestnuts is very different from that of other potatoes. The soil has a high moisture content, is heavy and sandy, and compared with other potatoes, water chestnuts are crisp and tender and easy to be damaged. Equipment r...

Problems solved by technology

[0004] The traditional device has the following disadvantages: the harvesting of water chestnuts in traditional dry fields is mostly done with agricultural tools such as nail-toothed rakes, shovels, and plows, and side cutting of soil blocks is likely to cause a large number of water chestnuts. At the same time, the soil blocks cannot be further broken, and manual handling and separation are required The process is cumbersome and labor-intensive; the traditional potato harvesting machine adopts a single separation method of multi-layer lifting chain vibration, which cannot adapt to the sticky and heavy soil planting environment with high moisture content where water chestnuts grow. The mechanical crushing of water chestnuts by layer vibration impact is relatively large; traditional potato harvesting machines are easy to bury water chestnuts under the soil that is subsequently screened, and are easily buried and smashed by soil clods, which is not conducive to subsequent picking and collection of water chestnuts, increasing the Subsequent picking workload
