Description

Technical Field

[0001] The utility model relates to the field of agitators, and more specifically, to a sand suction pump agitator. Background Art

[0002] Submersible sand suction pumps are also called submersible mortar pumps and submersible sand pumps. The motor and water pump are coaxially submerged in the water to work. When working, an external stirring impeller is required to impact the sediment into a high-concentration turbulent flow, so that the water pump can achieve high-concentration silt suction.

[0003] After searching, the existing patent (publication number: CN212643095U) discloses a combined sand suction pump, including a sand suction pump body, an external agitator, a connecting seat and a supporting mechanism, wherein the external agitator is symmetrically arranged on the outside of the sand suction pump body, and the external agitator and the sand suction pump body are connected through the connecting seat, and an inlet is opened on the sand suction pump body. The beneficial effects of the utility model are: through the designed supporting mechanism, the external agitator and the sand suction pump body are further supported when they are connected, which solves the problem of insufficient support when the external agitator and the sand suction pump body are connected in the traditional way; through the designed lifting mechanism, the stable installation of the lifting ring is realized, and the lifting ring can be disassembled and replaced when it is damaged.

[0004] The existing sand suction pump agitator has a simple structure and generally has no buffer or protective structure. The agitator is often in contact with sand and stones. If it accidentally touches a large stone, it will be seriously damaged. Once damaged, the entire agitator head needs to be replaced, which is very expensive. At the same time, the above-cited patent document does not propose a relevant solution to solve the above problem.

[0005] Therefore, a sand suction pump agitator is proposed to solve the above problems. Utility Model Content

[0017] 1. Compared with the prior art, the sand suction pump agitator is provided with a driving shaft, a driven shaft and a transmission cylinder. When clearing sand, the submersible motor drives the driving shaft to rotate, and the linkage convex rod on the driving shaft is embedded in the transmission groove of the transmission cylinder, so that the transmission cylinder can be driven to rotate synchronously, and the limiting convex rod of the driven shaft is inserted into the limiting groove, so the driven shaft can rotate synchronously with the transmission cylinder, driving the stirring assembly to rotate, and the sediment sediment is impacted into a high-concentration turbulent flow. When the stirring assembly encounters objects such as large stones and the rotation is restricted, the limiting convex rod on the driven shaft will move along the arc transition of the limiting groove, so that the transmission cylinder moves downward, thereby causing the linkage convex rod to separate from the transmission groove, that is, the driven shaft stops rotating, avoiding damage to the stirring assembly due to forced rotation, and extending the service life of the device.

[0018] 2. Compared with the prior art, the upper mounting plate and the lower mounting plate of the stirring assembly of the sand suction pump agitator are connected by a buffer spring and a guide column, that is, an elastic buffer structure is formed between the two, which can buffer the impact occurring when the stirring assembly dives. In addition, the stirring blades of the stirring assembly are separately connected to the lower mounting plate and are convenient for disassembly and assembly. When a single stirring blade is seriously damaged, it can be replaced separately to reduce maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
