Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction mechanisms, in particular to a dust reduction mechanism for a concrete mixing plant. Background Art

[0002] A concrete mixing plant is a facility for producing concrete, usually composed of various equipment and machinery, used for mixing cement, aggregates (such as sand, stones), water and other additives to produce various concrete formulations. These sites are usually used in construction sites or other engineering projects that require a large amount of concrete. The main function of a concrete mixing plant is to fully mix the raw materials to ensure that the quality and performance of the concrete meet the design requirements.

[0003] Chinese Patent with the publication number CN220113658U discloses a dust reduction mechanism for a concrete mixing plant. The dust reduction mechanism drives the driving gear to rotate through the operation of a servo motor, drives the rotating shaft to rotate through the meshing action between the driving gear and the driven gear, and then drives the rotating chassis to rotate on the bottom box, so as to adjust the spraying direction of the fog cannon barrel. And the fog cannon barrel reciprocates through the forward and reverse rotation of the servo motor, expanding the spraying coverage area of the fog cannon barrel. In addition, the angle between the fog cannon barrel and the bottom box can be adjusted through the operation of a cylinder, further improving the spraying area and ensuring the actual dust removal and reduction effect of the concrete mixing plant.

[0004] However, there is a lot of dust in the concrete mixing plant. When the fog cannon barrel operates, a large suction force will be generated at its air inlet end. Although an interception net is installed at the air inlet end in the above patent, only larger sand and stones can be intercepted, and dust is still easily sucked into the inside of the fog cannon barrel, which not only affects the quality of the sprayed water mist, but also the dust is easily attached to the fan, affecting its use effect and service life. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a dust reduction mechanism for a concrete mixing plant that can prevent dust from entering the inside of the fog cannon barrel.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows.

[0007] A dust reduction mechanism for a concrete mixing plant includes a bottom box. A fog cannon barrel is installed on the upper surface of the bottom box. A dust-proof net is installed at the air inlet end of the fog cannon barrel. A collar is sleeved on the outer surface of the dust-proof net. A driving mechanism capable of driving the collar to rotate is arranged on the outer surface of the fog cannon barrel. A U-shaped bracket is installed on the outer surface of the collar. An installation block is arranged on the outside of the U-shaped bracket. A through groove is opened inside the installation block. A connecting block is inserted into the through groove. A fixing mechanism capable of fixing the connecting block is arranged inside the installation block. A brush plate is installed at the end of the connecting block. Brush bristles are arranged on the outer surface of the brush plate.

[0008] It can be seen that through the setting of the dust-proof net, the dust in the concrete mixing plant can be intercepted to prevent the dust from entering the inside of the fog cannon barrel. And through the setting of the driving mechanism and the brush plate, the brush plate can be driven to rotate and clean the dust-proof net, avoiding excessive accumulation of dust on the surface of the dust-proof net and affecting the air circulation. And through the setting of the fixing mechanism, when the bristles on the surface of the brush plate are worn and deformed, it can be conveniently replaced, which is convenient to use.

[0009] Furthermore, the driving mechanism includes a support frame installed on the outer surface of the fog cannon barrel. An electric motor is installed at the end of the support frame, and a driving gear is installed at the end of the output shaft of the electric motor. A toothed ring is sleeved on the outer surface of the collar, and the toothed ring is meshed and connected with the driving gear.

[0010] When the electric motor is started, its output shaft drives the driving gear to rotate. Due to the meshing relationship between the driving gear and the toothed ring, the collar can be driven to rotate, and the brush plate is driven to clean the surface of the dust-proof net.

[0011] Furthermore, the fixing mechanism includes two inner grooves opened inside the mounting block. Guide rods are inserted into the two inner grooves. Shoulder shafts are arranged on the outer surfaces of the guide rods. A first spring is sleeved on the outer surface of the guide rod. The two ends of the first spring are respectively abutted against the shoulder shaft and the inner wall of the inner groove. One ends of the two guide rods are jointly installed with a connecting plate. An insertion block is installed on the outer surface of the connecting plate. A slot is opened on the outer surface of the connecting block, and the insertion block is adapted to the slot.

[0012] When replacing the brush plate, the guide rod can be pressed inward. The guide rod drives the connecting plate to move, and the connecting plate drives the insertion block to be withdrawn from the inside of the slot, so that the connecting block loses its fixation, and then the brush plate can be removed. When installing the brush plate, first press the guide rod to drive the insertion block to be withdrawn from the through slot, then insert the connecting block into the through slot and align the slot with the insertion block, and then release the guide rod. The compressed first spring releases its elastic force, so that the insertion block can be driven to insert into the slot to complete the installation of the brush plate.

[0013] Furthermore, balls are evenly arranged on the outer surface of the air inlet end of the fog cannon barrel.

[0014] Through the setting of the balls, the friction between the outer surface of the air inlet end of the fog cannon barrel and the inner wall of the collar can be reduced, wear can be reduced, and the rotation of the collar can be more smooth.

[0015] Furthermore, two telescopic rods are installed on the outer surface of the U-shaped bracket. The ends of the telescopic rods are connected to the mounting block. A second spring is sleeved on the outer surface of the telescopic rod. The two ends of the second spring are respectively abutted against the U-shaped bracket and the mounting block.

[0016] Through the settings of the telescopic rod and the second spring, the mounting block has a certain amount of movement space, which facilitates the extraction or installation of the connecting block from the inside of the through groove. Moreover, under the push of the second spring, the bristles of the brush plate can be made to fit against the surface of the dust-proof net, avoiding the situation where there are gaps between the two, which may lead to poor cleaning effects.

[0017] Furthermore, the other ends of the two guide rods are jointly equipped with a pressing plate, and a rubber pad is arranged on the outer surface of the pressing plate.

[0018] Through the setting of the pressing plate, it is convenient to press the two guide rods simultaneously. And through the setting of the rubber pad, the friction with the hand can be increased, reducing the situation of hand slipping. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following provides a detailed description of the present utility model with reference to the accompanying drawings.

[0026] As Figures 1-5As shown in the figure, a dust reduction mechanism for a concrete mixing plant includes a bottom box 100. A fog cannon barrel 101 is installed on the upper surface of the bottom box 100. A dust-proof net 102 is installed at the air inlet end of the fog cannon barrel 101. A collar 103 is sleeved on the outer surface of the dust-proof net 102. A driving mechanism 200 capable of driving the collar 103 to rotate is arranged on the outer surface of the fog cannon barrel 101. A U-shaped bracket 104 is installed on the outer surface of the collar 103. An installation block 105 is arranged on the outside of the U-shaped bracket 104. A through groove 106 is opened inside the installation block 105. A connecting block 107 is inserted into the through groove 106. A fixing mechanism 300 capable of fixing the connecting block 107 is arranged inside the installation block 105. The end of the connecting block 107 is installed with a brush board 108, and bristles are arranged on the outer surface of the brush board 108.

[0027] When the fog cannon barrel 101 is started, the dust-proof net 102 can filter the dust in the air entering its interior, avoiding the influence of dust on the quality of the sprayed water mist and the fan inside the fog cannon barrel 101. Since there is a lot of dust in the concrete mixing plant, while the fog cannon barrel 101 is started, the driving mechanism 200 can drive the brush board 108 to continuously clean the dust-proof net 102, avoiding excessive accumulation of dust on the surface of the dust-proof net 102 and affecting the air circulation. And through the setting of the fixing mechanism 300, when the bristles on the surface of the brush board 108 are worn and deformed, it is convenient to replace it, which is convenient to use.

[0028] Specifically, the driving mechanism 200 includes a support frame 201 installed on the outer surface of the fog cannon barrel 101. A motor 202 is installed at the end of the support frame 201. A driving gear 203 is installed at the end of the output shaft of the motor 202. A toothed ring 204 is sleeved on the outer surface of the collar 103. The toothed ring 204 is meshed and connected with the driving gear 203. When the motor 202 is started, its output shaft drives the driving gear 203 to rotate. Due to the meshing relationship between the driving gear 203 and the toothed ring 204, the collar 103 can be driven to rotate, and the brush board 108 can be driven to clean the surface of the dust-proof net 102.

[0029] Specifically, the fixing mechanism 300 includes two inner grooves 301 opened inside the mounting block 105. Guide rods 302 are inserted into the interiors of the two inner grooves 301. Shoulder 303 is provided on the outer surface of the guide rod 302. A first spring 304 is sleeved on the outer surface of the guide rod 302. The two ends of the first spring 304 are respectively abutted against the shoulder 303 and the inner wall of the inner groove 301. One ends of the two guide rods 302 are jointly installed with a connecting plate 305. An insertion block 306 is installed on the outer surface of the connecting plate 305. A slot 307 is opened on the outer surface of the connecting block 107. The insertion block 306 is adapted to the slot 307. When replacing the brush plate 108, the guide rod 302 can be pressed inward. The guide rod 302 drives the connecting plate 305 to move. The connecting plate 305 drives the insertion block 306 to be withdrawn from the interior of the slot 307. Therefore, the connecting block 107 loses its fixation, and then the brush plate 108 can be removed. When installing the brush plate 108, first press the guide rod 302 to drive the insertion block 306 to be withdrawn from the through groove 106. Then insert the connecting block 107 into the through groove 106 and align the slot 307 with the insertion block 306. Then release the guide rod 302. The compressed first spring 304 releases its elastic force. Therefore, it can drive the insertion block 306 to be inserted into the slot 307 to complete the installation of the brush plate 108.

[0030] Specifically, balls 400 are evenly arranged on the outer surface of the air inlet end of the fog cannon barrel 101. Through the arrangement of the balls 400, the frictional force between the outer surface of the air inlet end of the fog cannon barrel 101 and the inner wall of the collar 103 can be reduced, wear can be reduced, and the rotation of the collar 103 can be made more smooth.

[0031] Specifically, two telescopic rods 500 are installed on the outer surface of the U-shaped bracket 104. The end of the telescopic rod 500 is connected to the mounting block 105. A second spring 501 is sleeved on the outer surface of the telescopic rod 500. The two ends of the second spring 501 are respectively abutted against the U-shaped bracket 104 and the mounting block 105. Through the arrangement of the telescopic rod 500 and the second spring 501, the mounting block 105 has a certain movement space, which is convenient for withdrawing or installing the connecting block 107 from the interior of the through groove 106. And under the push of the second spring 501, the bristles of the brush plate 108 can be made to fit the surface of the dust-proof net 102, avoiding the situation that there is a gap between the two resulting in poor cleaning effect.

[0032] Specifically, a pressing plate 600 is jointly installed at the other ends of the two guide rods 302. A rubber pad is provided on the outer surface of the pressing plate 600. Through the arrangement of the pressing plate 600, it is convenient to press the two guide rods 302 simultaneously. And through the arrangement of the rubber pad, the frictional force with the hand can be increased to reduce the situation of hand slipping.
