Title:
FARMLAND IRRIGATION AND DRAINAGE MECHANICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/021757
Kind Code:
A1
Abstract:
A farmland irrigation and drainage mechanical apparatus, comprising an irrigation and drainage special-shaped traveling assembly (1), a filtering type circulating water suction assembly (2) and a telescopic moving box (3). The irrigation and drainage special-shaped traveling assembly (1) comprises an advancing special-shaped front wheel (4), an advancing rear wheel (5), a driving electric motor (6), a driving gear (7), a driven gear (8), a transmission gear (9), a special-shaped driving gear (10), a fixing flat plate (11) and a supporting frame (12). Contact points between the farmland irrigation and drainage mechanical apparatus and the ground and crops are reduced during an advancing process; the farmland irrigation and drainage mechanical apparatus can easily advance in farmland; the weight of the farmland irrigation and drainage mechanical apparatus is reduced on the premise that a good supporting force is ensured; damage to the crops can be reduced; a controller (20) determines whether water in the farmland is pumped or whether water in a water tank (15) is discharged into the farmland according to a water level height signal sent by a liquid level sensor (13) so as to achieve cyclic utilization of the water; an appropriate water level condition can be maintained in the farmland; and a spring (26) is arranged in a supporting box body (25) and is sleeved on a telescopic rod (27) to perform buffering during the advancing process.
