[0002] When the mortar raw materials are mixed for production, a mixer is needed to mix the mortar. When the mixer is mixing the mortar, the mortar raw materials will produce floating objects that drift to the outside, which can easily pollute the environment. Therefore, a structure is needed to remove and collect the dust generated by the mixing mortar to reduce pollution to the environment.

[0003] Prior art, such as the invention patent document with authorization announcement number "CN116531876A" and patent name "A dust removal and water circulation recovery system for a concrete mixing plant", discloses a dust removal and water circulation recovery system for a concrete mixing plant, the system includes a factory building, a steel truss is arranged on the top of the factory building, a spray device and a collection device are arranged in the factory building, the spray device includes a plurality of spray pipes fixed on the steel truss; the collection device includes a water vapor collection device and a spray water collection device; the spray water collection device includes a plurality of drainage channels opened in the factory building and a plurality of water collection tanks connected to the drainage channels.

[0004] In actual use, in order to achieve dust removal in the factory, the above patent document uses a spray device to spray water mist to combine the dust with the water mist and make it fall down to form dust reduction. However, the height of the spray pipe of the spray device is fixed during spraying, so its spray range is locked, resulting in a dust reduction blind spot, which reduces the dust removal effect. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a material sand stirring and collecting device with a dust removal effect, which is used to solve the technical problem that the height of the spray pipe of the spray device in some material sand stirring and collecting devices with a dust removal effect mentioned in the background technology is fixed during spraying, so the spray range is locked, resulting in the formation of dust reduction dead corners and reducing the dust removal effect.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A material sand mixing and collecting device with dust removal effect comprises a base, a mixing drum and a collecting vehicle arranged on the base, a dust removal cover which can be raised and lowered is arranged above the mixing drum and the collecting vehicle, a vertical first transmission shaft is rotatably arranged inside the dust removal cover, a supporting disc is threadedly connected to the first transmission shaft, and a stopper is arranged on the supporting disc; a circle of rotatable annular rack is arranged on the outer side of the supporting disc, a vertical rack is arranged on the stopper, and a connecting assembly is arranged on the supporting disc, and the connecting assembly is respectively engaged with the rack and the annular rack for rotating the annular rack; two mounting plates are fixedly arranged on the outer side of the annular rack, a spray pipe is fixedly arranged between the two mounting plates, and the water outlet of the spray pipe faces the dust removal cover; a water storage box is fixedly arranged at the bottom of the supporting disc, and the spray pipe is conductively connected with the water storage box; an air intake pipe is arranged on the inner top wall of the dust removal cover, a condensation conversion assembly is arranged on the top of the dust removal cover, the air intake pipe is connected with the inlet end of the condensation conversion assembly, and the outlet end of the condensation conversion assembly is conductively connected with the water storage box.

[0008] Working principle:

[0009] When in use, lift the dust cover upwards, then match the collection vehicle with the outlet of the mixing drum, and then lower the dust cover, with the dust cover set above the collection vehicle and the mixing drum;

[0010] Then the first transmission shaft is rotated, and the rotation of the first transmission shaft drives the supporting disc to move vertically; at the same time, the vertical movement of the supporting disc drives the connecting assembly to engage with the rack and the annular rack respectively, so that the annular rack rotates, and the rotation of the annular rack drives the spray pipe to rotate to spray and reduce dust on the mixing drum;

[0011] At the same time, the evaporated spray water enters the condensation conversion assembly through the air inlet pipe, and then is discharged into the water storage box through the outlet end after the condensation effect of the condensation conversion assembly. The water in the water storage box is discharged into the spray pipe, and then sprayed out by the spray pipe to spray and reduce dust. The cycle is repeated to achieve the purpose of dust removal.

[0012] Beneficial effects:

[0013] 1. By setting up a dust removal cover, the collection vehicle and the mixing drum are covered to reduce the dust reduction space, prevent the floating objects generated by the mixing drum from drifting to the outside, and improve the dust reduction effect;

[0014] 2. By setting a first transmission shaft, a support disc and a limit piece, the vertical movement of the support disc is realized; an annular rack, a rack and a connecting assembly are set. Since the connecting assembly is respectively engaged with the rack and the annular rack, the vertical movement of the support disc is driven to rotate while the annular rack is driven; by setting a spray pipe, the water mist sprayed from the spray pipe can be combined with the floating objects floating in the dust hood, thereby achieving the effect of spraying and dust reduction, and achieving the purpose of dust removal; since the spray pipe is connected to the annular rack, the rotation of the annular rack drives the spray pipe to rotate to spray and remove dust inside the dust hood, thereby expanding the spray range.

[0015] Therefore, in combination with the cooperation of the above components, the spray pipe is driven by rotating the first transmission shaft to rotate around the supporting disc while moving vertically to spray water mist to spray and reduce dust on floating objects in the dust removal cover, so that the water mist contacts the floating objects in the largest range, reduces the occurrence of dust removal dead angles, and improves the dust removal effect; and the operation is simple, and multiple effects can be achieved simultaneously by simply rotating the first transmission shaft;

[0016] 3. By setting up a water storage box, an air intake pipe, and a condensation conversion component, the evaporated spray water enters the condensation conversion component, and then is discharged into the water storage box through the outlet after condensation by the condensation conversion component, thereby collecting and reusing the spray water, improving the utilization of water resources, and being more energy-saving and environmentally friendly.
