NOVELTY - A manual and electrical dual-purpose sprinkling-irrigating vehicle for pumping and transporting biogas dreg and biogas slurry, comprises wheels (1), a vehicle bottom plate (2), a handrail (7), and a parking bracket (4); where a tool box (27) is mounted on the vehicle bottom plate (2); a vehicle box (23) for filling biogas dreg and biogas slurry is mounted above the tool box (27); a pump body (13) of a piston pump (12) is mounted outside a front plate (15) of the vehicle box (23); and a piston (10) in the pump body (13) is fixedly mounted on the bottom end of a piston rod (11).    USE - The manual and electrical dual-purpose sprinkling-irrigating vehicle is useful for pumping and transporting biogas dreg and biogas slurry (claimed).    ADVANTAGE - The manual and electrical dual-purpose sprinkling-irrigating vehicle is simply and conveniently operated; where it is small-sized, flexible, and low in price. Moreover, it can frequently transport inlet and outlet small amounts of biogas dregs and biogas slurries out of family methane-generating pit in rural areas, and can sprinkle and irrigate biogas slurries to vegetable plots and gardens.    DETAILED DESCRIPTION - A manual and electrical dual-purpose sprinkling-irrigating vehicle for pumping and transporting biogas dreg and biogas slurry, comprises wheels (1), a vehicle bottom plate (2), a handrail (7), and a parking bracket (4); where a tool box (27) is mounted on the vehicle bottom plate (2); a vehicle box (23) for filling biogas dreg and biogas slurry is mounted above the tool box (27); a pump body (13) of a piston pump (12) is mounted outside a front plate (15) of the vehicle box (23); a piston (10) in the pump body (13) is fixedly mounted on the bottom end of a piston rod (11); the top end of the piston (10) is mounted with a piston pumping device; the right end of a feeding pipe (17) is fixedly mounted on the bottom of the external side wall of the pump body (13) and communicated with a pump cavity (32); the left end of the feeding pipe (17) extends into the vehicle box (23) from the bottom of the front plate (15) of the vehicle box (23); the opening of the upper end of the left end of the feeding pipe (17) is mounted with a one-way feeding valve (16); the left end of a pumping pipe (8) is fixedly mounted on the bottom plate outside the pump body (13) and communicated with the pump cavity (32); the opening of the left end of the pumping pipe (8) in the pump body (13) is mounted with a one-way pumping valve (9); the opening of the right end of the pumping pipe (8) is outward to be conveniently connected with a plastic corrugated pipe communicated with a methane-generating pit; the bottom outside the rear plate (24) of the vehicle box (23) is mounted with a discharging pipe (26) with a discharging valve (25); a box cover (21) on the top end of the box body (23) is mounted with an atomizing switch (18); and an atomizing hose (29) is connected between the atomizing switch (18) and a spray gun (22).
