[0017] Beneficial effects:

[0018] (1) The concrete block blowing device is provided with a blowing assembly in the device. The blowing assembly uses a cylinder assembly to adjust two groups of blowing plates accordingly for concrete blocks of different thicknesses. Then, air is supplied through an air compressor and other components to improve the blowing efficiency.

The three-way valve is switched at a fixed time to allow the injection bar to spray compressed air, which promotes the falling off of impurities attached to the outer surface of the filter frame. The motor in the auger component cooperates with the auger to guide the impurities in the conveying shell out of the device, thereby playing a role in graded recovery.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-3 The first embodiment shown is a concrete block blowing device, comprising a base 1, the upper end of which is provided with a cleaning member for cleaning the concrete block, the cleaning member comprising: a roller assembly 2, mounted at both ends of the upper side of the base 1 for introducing the concrete block; a frame 3, disposed in the middle of the upper side of the base 1;

[0026] A purge assembly 4 is installed on both ends of the upper side of the base 1 for cleaning concrete blocks. The purge assembly 4 includes an air compressor 41 fixedly connected to the base 1. A three-way valve 42 is connected to the output end of the air compressor 41. A first bifurcated pipe 43 is fixedly connected to the upper end of the three-way valve 42. A branch pipe 44 is installed on the other side of the three-way valve 42. A cylinder assembly 45 is installed at the middle end of the top of the frame 3. A first purge plate 46 is installed at the bottom of the cylinder assembly 45. A second purge plate 47 is installed on the upper side of the base 1 near the middle end of the frame 3. The first purge plate 46 and the second purge plate 47 are both fixedly connected to the first bifurcated pipe 43.

[0027] The dust removal assembly 5 is installed on the frame 3 for dust treatment; the front and rear sides of the frame 3 are both provided with slots near the roller assembly 2, and the upper side of the frame 3 is provided with a curtain near the slotted end; the first bifurcated pipe 43 is provided with a bellows near the end of the first purge plate 46, and the first bifurcated pipe 43 is fixedly connected to the first purge plate 46 through the bellows, and a plurality of air jet holes are provided at the lower end of the first purge plate 46 and the upper side of the second purge plate 47; the first purge plate 46 and the second purge plate 47 are both arc-shaped plates, and the second purge plate 47 is located between the two groups of roller assemblies 2, and the top of the second purge plate 47 is lower than the top height of the roller assembly 2;

[0028] The cylinder assembly 45 adjusts the height of the first purge plate 46 so that the spacing between the first purge plate 46 and the second purge plate 47 matches the concrete blocks of corresponding thickness. When the concrete blocks of corresponding width pass through the first purge plate 46 and the second purge plate 47, the air compressor 41 generates compressed air which is ejected through the three-way valve, the first bifurcated pipe 43, the first purge plate 46 and the second purge plate 47 to purge both sides and the edge of the concrete blocks, thereby promoting the falling of waste materials on the surface of the concrete blocks. The blown-off waste materials move toward the dust removal assembly 5 with the air flow, wherein the curtain cooperates with the frame 3 to shield the dust and waste materials generated by the purge, thereby reducing dust pollution.

[0029] like Figure 1-3 The second embodiment shown is mainly different from the first embodiment in that:

[0030] The dust removal assembly 5 includes a dust suction pump assembly 51 disposed on the top of the base 1, a second bifurcated pipe 52 is installed at the suction end of the dust suction pump assembly 51, auger assemblies 53 are installed at both ends of the inner side of the frame 3, filter frames 54 for blowing and filtering dust are installed near the ends of the auger assemblies 53 on both sides of the frame 3, and a spray bar 55 fixedly connected to the branch pipe 44 is installed on the upper side of the frame 3 near the suction end of the filter frame 54;

[0031] The second bifurcated pipe 52 is fixedly connected to the two groups of filter frames 54 respectively. The auger assembly 53 includes a conveying shell fixedly connected to the frame 3. The conveying shell is provided with a receiving groove near the inner side of the frame 3. The receiving groove is located at the lower side of the filter frame 54. An auger is installed in the conveying shell. A motor for driving the auger is installed on the back side of the conveying shell. A discharge pipe is provided on the lower side of the conveying shell away from the motor. A dust bag is installed at the exhaust end of the dust suction pump assembly 51. A plurality of injection holes connected to the branch pipe 44 are provided at the bottom of the injection bar 55 near the filter end of the filter frame 54.

[0032] A recovery box is placed at the lower end of the discharge pipe of the auger assembly 53 to ensure that the open end of the recovery box fits well with the bottom of the discharge pipe. The dust suction pump assembly 51 absorbs the dust generated by the purging through the second bifurcated pipe 52 and the filter frame 54. The filter frame 54 filters the large particles of impurities in the dust, and the small particles of dust are finally introduced into the dust collecting bag by the dust suction pump assembly 51. Some of the large particles of impurity dust retained on the filter frame 54 fall into the conveying shell through the receiving groove under the action of gravity. The three-way valve 42 is reversed at a fixed time. At this time, the compressed air generated by the air compressor 41 is sprayed out through the branch pipe 44 and the injection strip 55, which promotes the falling off of impurities attached to the outer surface of the filter frame 54.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0034] When in use, the user places a recovery box at the end of the discharge pipe at the lower side of the auger assembly 53, introduces the processed concrete blocks to be purged into the frame 3 through the roller assembly 2 and the curtain, and lets the cylinder assembly 45 adjust the height of the first purge plate 46 so that the bottom of the first purge plate 46 is close to the upper end of the concrete block, and starts the air compressor 41, the dust suction pump assembly 51, and the auger assembly 53. The air compressor 41 draws in and compresses the outside air, and then the compressed air is sprayed from the first purge plate 46 and the second purge plate 47 through the three-way valve 42 and the first bifurcated pipe 43, and the first purge plate 46 and the second purge plate 47 respectively purge the two sides and edges of the concrete block to promote the shedding of waste materials on the surface of the concrete block;

[0035] The curtain blocks the dust and fallen impurities generated by the purging. Under the action of compressed air and the curvature of the first purge plate 46 and the second purge plate 47, the fallen waste moves toward the auger assembly 53 at the inner ends of the frame 3 and finally falls into the conveying shell. The motor drives the auger to rotate, and the rotating auger conveys the waste and finally leads it out from the discharge pipe. In the above process, the dust suction pump assembly 51 absorbs the dust generated by the purging through the second bifurcated pipe 52 and the filter frame 54, the filter frame 54 filters the large particles of impurities in the dust, and the small particles of dust are finally introduced into the dust collecting bag by the dust suction pump assembly 51.
