Water chestnut digger

Abstract

The invention discloses a water chestnut digger. The water chestnut digger comprises a digging shovel, and further comprises a crank driving mechanism, wherein a first conveying device capable of conveying soil is connected to the upper end of the digging shovel; a jigging sieve body is arranged below the first conveying device; the digging shovel is connected with a lower longitudinal beam; the lower longitudinal beam is connected to the outer wall of the jigging sieve body; a sieve plate, a flow-guiding plate and a guide slot which are sequentially connected are formed inside the jigging sieve body; the sieve plate, the flow-guiding plate and the guide slot form a cross section plate of the jigging sieve body; the crank driving mechanism is connected with the sieve plate; the guide slotis connected to the inner wall of the jigging sieve body; a soil discharging roll is arranged at the bottom end of the jigging sieve body. Water chestnuts and the soil are moved rightwards layer by layer under the action of vibration and a water flow, and the flow-guiding plate guides the water chestnuts into the guide slot, so that mechanized harvesting of the water chestnuts is achieved, the labor intensity is greatly reduced and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural excavating equipment, in particular to a water chestnut excavator. Background technique [0002] Water chestnut is a kind of perennial herb planted in paddy fields. The apex of its underground stolon expands into an oblate corm with a diameter of 15-50 mm and a thickness of 10-35 mm. The corm generally grows 90-250 mm underground. The bulbs of water chestnuts mature at the end of autumn and are excavated and listed in winter and spring. Water chestnuts are white in flesh, sweet and juicy, crisp and delicious. They can be used as both fruit and vegetable, and are a popular seasonal product. Due to the characteristics of the paddy field soil where water chestnuts are grown, potato excavators and other machines for harvesting tuber crops cannot harvest water chestnuts. Therefore, at present, manual digging is mainly used for harvesting water chestnuts, resulting in high labor intensity, low pro...

Problems solved by technology

Due to the soil characteristics of the paddy fields where water chestnuts are grown, potato excavators and other machines for harvesting tuber crops cannot harvest water chestnuts. Therefore, at present, manual digging is mainly used for harvesting, resulting in high labor intensity, low production efficiency, and difficult working environment.
