The utility model discloses a plunger type soil sand pump theory of operation as follows:
the first step is soil absorption: when soil suction is started, as shown in fig. 3 and 3a, the soil discharging cylinder 5 is in a fully extended state, and the soil discharging valve 2 is closed. Meanwhile, the soil suction oil cylinder is in a fully contracted state, and the soil inlet valve 7 is opened at the moment. Then, the dumping plunger 11 is driven by the retraction of the piston rod of the dozer cylinder 13 to retract. At the moment, the volume in the cavity of the pump body 8 is gradually increased, and soil body flows into the cavity of the pump body 8 from the soil hopper 6.
The soil discharging plunger 11 is driven by the retraction of the piston rod of the soil pushing cylinder 13 to further retract, the volume in the cavity of the pump body 8 becomes larger along with the retraction, and more soil is fed into the cavity, as shown in fig. 3 b.
Finally, when the dumping plunger 11 is driven by the piston rod of the dozer cylinder 13 to retract to the bottom, as shown in fig. 3 c. At this time, the volume in the cavity of the pump body 8 is also increased to the maximum, and the soil is also moved into the maximum. Then the soil is discharged by reversing.
The second step is dumping: before the soil discharging is started, the soil discharging oil cylinder 5 is required to be in a fully contracted state, and the soil discharging valve 2 is opened. At the same time, the soil inlet cylinder 17 must be in the fully extended state, and the soil inlet valve 7 is closed, as shown in fig. 4 and 4 a. Then, the dumping plunger 11 is driven by the extending piston rod of the dozer cylinder 13 to extend. At the moment, the volume in the cavity of the pump body 8 is gradually reduced, and soil can be only discharged through the soil discharge pipe 1 after being compressed.
Then, the soil discharging plunger 11 is further extended under the driving of the extending of the piston rod of the soil pushing cylinder 13, the volume in the cavity of the pump body 8 is also smaller, and more soil is discharged, as shown in fig. 4 b.
Finally, when the dumping plunger 11 is driven by the piston rod of the dozer cylinder 13 to reach the end, as shown in fig. 4 c. The volume in the cavity of the pump body 8 is minimized, and when the discharged soil is maximized, the plunger type soil sand pump completes a soil sucking-discharging process. The plunger type sand pump enters a normal working procedure only by continuously repeating the soil sucking-discharging process.
The present invention is not limited to the above specific embodiments, and for those skilled in the art, the above conception can be used without any creative work, and all the changes made fall within the protection scope of the present invention.
