The invention discloses a double-cylinder piston type mortar pump which comprises a transporting cylinder, a first hydraulic cylinder, a second hydraulic cylinder, a discharge pipe, a first mortar discharging pipe, a second mortar discharging pipe, a first mortar suction pipe and a second mortar suction pipe, wherein the first hydraulic cylinder is connected with a left-end piston rod of the transporting cylinder, the second hydraulic cylinder is connected with a right-end piston rod of the transporting cylinder, and the first hydraulic cylinder and the second hydraulic cylinder drive a piston of the transporting cylinder to reciprocate; the first mortar discharge pipe with the pipeline provided with a first mortar outlet valve is connected with a left cavity of the transporting cylinder; the first mortar suction pipe with the pipeline provided with a first mortar inlet valve is connected with the left cavity of the transporting pipe; the second mortar discharging pipe with the pipeline provided with a second mortar outlet valve is connected with a right cavity of the transporting cylinder; and the second mortar suction pipe with the pipeline provided with a second mortar inlet valve is connected with the right cavity of the transporting cylinder; and the first mortar outlet pipe and the second mortar outlet pipe are both connected with the discharge pipe. The double-cylinder piston type mortar pump has good mortar outlet continuity, uniformity and stability during pump transportation.
Description
technical field [0001] The invention relates to the field of construction machinery, in particular to a double-cylinder piston type mortar pump. Background technique [0002] At present, among the mortar pumps, most of the screw pumps are used to pump the mortar. The screw pump has the advantages of simple structure, low cost, and continuous pumping, but the screw is easy to wear and the cost of replacing the screw is high. Long life, low cost of replacing the piston and other advantages. [0003] In the prior art, some piston-type mortar pumps use a cam to drive the piston to reciprocate. The mechanical structure is relatively complicated, the cost is high, the variable displacement adjustment operation is complicated, and the speed change range is small. Some mortar pumps use a crank-link mechanism to drive the piston to reciprocate, which is prone to eccentric force, causing rapid wear between the piston and the piston cylinder. At the same time, the variable displacemen...
