Description

Technical Field

[0001] This utility model relates to the technical field of mortar mixers, and specifically discloses a mortar mixer. Background Technology

[0002] Mortar mixers are an indispensable piece of equipment in the construction industry, used to produce mortars with various properties. With the development of construction technology, the demand for portability of mortar mixers is constantly increasing; especially in practical applications such as tankless design and mobility.

[0003] In existing technologies, mortar mixers are mostly designed as tanks or cylinders, requiring materials to be added into the tank, mixed, and then discharged. These mixers are suitable for large-scale operations, but small-scale operations with limited space cannot accommodate the introduction of larger equipment such as tanks or cylinders. Furthermore, tank mixers require subsequent tank washing, reducing operational portability. Meanwhile, small-scale operations still involve adding materials to buckets or mud pits and mixing directly in the open air, making tank mixers unsuitable. Therefore, a mortar mixer suitable for small-scale operations is needed. On the one hand, in open-air mixing, hand-held mixing paddles are typically used, reducing operational convenience, or support rods are used to suspend the mixing paddle, but this results in instability and the paddle easily vibrating and shifting. On the other hand, open-air mixing easily generates significant dust, polluting air quality and affecting the health of workers.

[0004] Therefore, solving the above problems and designing a mortar mixer suitable for small-scale operations is of great significance. Summary of the Invention

[0005] The purpose of this invention is to provide a mortar mixer that solves the problems existing in the current device.

[0019] In the scheme, water enters the fixed water pipe through the water inlet hose, and the water is sprayed from the atomizing nozzle to form water mist by using the pressure valve and the throttle valve, thereby achieving the dust reduction effect.

[0020] More preferably, the spray dust collector includes a fixed water pipe with closed two ends; the pipe wall close to one end of the internally threaded pipe is provided with an external thread matched with the internal thread of the internally threaded pipe.

[0024] More preferably, the water inlet is arranged between the bottom line of the outer thread and the upper line of the closest atomizing nozzle.

[0025] Compared with the prior art, the beneficial effects of the present application are:
