Problems solved by technology

[0003] At present, due to the different rotation direction of the impeller, the number of impellers, and the position of the inlet of the two-stage pump, the main pump of the existing guest soil sprayer has many disadvantages in the process of use, as follows: 1. The main pump of the sprayer Most of them are single-stage impellers, and the head is generally low; 2. The impeller of the main pump of the spray seeder is right-handed when viewed from the coupling end when it is working, which is the same as the rotation direction of the power machine such as a diesel engine, so it can only pass through the power machine. The coupling or the belt is connected at both ends on the same axis, that is, the installation position of the pump and the power machine (such as a diesel engine) can only be directly connected and installed at both ends of the pulley and the coupling, and cannot be installed in parallel. The overall length and floor area; and the rigid connection through the coupling will make the load too large due to the large particles entering the pump body and the impeller will be stuck, thereby damaging the mud pump or diesel engine; 3. Although the existing spraying machine adopts A two-stage pump is added, but due to the limitation of the impeller rotation direction and the position of the pump inlet, the feed auger and the reversing synchronous gearbox are added, and the structure is more complicated, which increases the failure maintenance points and power loss, and reduces the cost of pumping at the same time. The head and service life of the sprayer

Abstract

The invention belongs to the technical field of spraying machinery, and particularly relates to an external soil spraying machine and a special two-stage energy-saving high-lift underflow pump for the external soil spraying machine. The underflow pump comprises a transmission shaft, a pump body, a bearing chamber and a coupling, wherein the pump body comprises a one-stage pump body, a two-stage pump body and a two-stage feed pump body; a one-stage impeller is fixedly mounted at the right end of the transmission shaft in a sleeving manner; an elbow is communicated between the one-stage pump body and the two-stage feed pump body; a guard plate is arranged between the two-stage feed pump body and the two-stage pump body; a locating sleeve is mounted on the transmission shaft between the two-stage feed pump body and the two-stage pump body in a sleeving manner; a two-stage impeller is mounted on the locating sleeve in a sleeving manner, and mounted between a radial flange at one end of the locating sleeve and the guard plate; a feed channel is formed between the guard plate and the locating sleeve; the one-stage impeller and the two-stage impeller are mounted back to back; the bending direction of a helical blade of the one-stage impeller is counterclockwise; the bending direction of a helical blade of the two-stage impeller is clockwise; a horizontal feed port is formed in the right end face of the one-stage pump body; and a discharge port is formed vertically in a tangential direction of the pump body on the front side of the two-stage pump body. The underflow pump is higher in lift, and is suitable for conveying viscous slurry; the structure of the spraying machine is simplified; the manufacturing cost and engineering use cost of the spraying machine are lowered; breakdown maintenance points of the spraying machine are decreased; and the power loss of equipment is reduced.

Description

technical field [0001] The invention belongs to the technical field of spraying machinery for planting herbs, shrubs, trees and other plants in slope greening, and in particular relates to a special two-stage thick slurry pump and a passenger soil spraying machine suitable for conveying viscous materials (mud, etc.). Soil sprayer. Background technique [0002] Nowadays, the guest soil spraying machine has gradually replaced the position of the dry spraying machine and the concrete delivery pump in the slope greening construction, and to a certain extent, it has solved the low efficiency of the dry spraying machine, high construction cost, more labor and the inconvenient movement of the delivery pump. , The disadvantage of construction danger. The so-called guest soil spraying machine is to mix grass seeds, shrubs, tree species, etc., with water-retaining agents, adhesives, plant fibers, planting soil and fertilizers, etc. The thick slurry pump sprays it on the slope. Sinc...
