Description

Technical Field

[0001] This utility model belongs to the technical field of construction machinery and equipment, specifically a sand and gravel mixing device for construction. Background Technology

[0002] Construction sand and gravel mixing equipment is a special equipment used in construction projects to mix raw materials such as sand, gravel, cement, and water in a certain proportion to produce composite building materials such as concrete and mortar. Its core function is to use mechanical mixing to ensure that the components are evenly mixed and that the physical properties of the finished material meet the construction requirements.

[0003] Traditional mixing devices mostly involve pouring raw materials directly into the device. This can cause the raw materials to "layer up" due to gravity, resulting in uneven initial mixing. This can lead to the formation of localized "cement clumps" that are difficult to break up later, resulting in uneven concrete strength or problems such as honeycomb and pitted surfaces.

[0004] Therefore, this utility model provides a sand and gravel mixing device for building construction. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, a construction sand and gravel mixing device includes a placement platform 1; a storage component 115 is installed at the bottom of the placement platform 1; a storage bucket body 11 is fixedly connected to the top of the placement platform 1 near the storage component 115; a first sealing cover 12 is detachably connected to the top of the storage bucket body 11; a first motor 13 is fixedly connected to the top of the first sealing cover 12; a rotating rod 14 is fixedly connected to the output end of the first motor 13; a plurality of equidistantly distributed storage bins 15 are detachably connected to the middle of the rotating rod 14; a guide groove 16 is fixedly connected to the middle of the storage bins 15 near the rotating rod 14. A top plate 18 is slidably connected to the middle of the guide groove 16; a plurality of springs 17 evenly distributed are fixed to the bottom of the top plate 18, and the other end is fixed to the storage bin 15; a gravity-flipping door 112 is opened in the middle of the storage bin body 11 away from the first sealing cover 12; a feeding plate 19 is fixed to the top of the placement platform 1 near the gravity-flipping door 112; a second motor 110 is fixed to the side wall of the feeding plate 19; a scraper 111 is fixed to the output end of the second motor 110; a stirring assembly 113 is installed at the end of the feeding plate 19 away from the storage bin body 11; a stirring assembly 113 is installed in the middle of the stirring assembly 113. The spray assembly 114, during operation, opens the first sealing cover 12 and places the sand and gravel raw materials in the middle of the storage bin 15. At this time, the weight of the raw materials presses the top plate 18 downwards. As the raw materials gradually decrease, the rebound force of the spring 17 lifts the top plate 18, and the guide groove 16 can limit its movement, allowing it to slide up and down in the middle of the storage bin 15. Then, the first motor 13 is started, and its output drives the rotating rod 14 and the storage bin 15 to rotate. When the raw materials in the middle of the storage bin 15 come into contact with the gravity-flipping door 112, the weight of the raw materials pushes the gravity-flipping door 112 open. The material then slides down to the top of the feed plate 19. At this time, the second motor 110 is started. The output end of the second motor 110 drives the scraper 111 to rotate, scraping the raw material evenly to the middle of the mixing assembly 113 for mixing. Through the above structure, the guide groove 16 and the spring 17 work together to make the raw material on the top of the top plate 18 fall evenly and orderly to the middle of the feed plate 19. Then, the scraper 111 slowly scrapes it into the interior of the mixing assembly 113, reducing the phenomenon of local material accumulation inside the mixing assembly 113 caused by the raw material rushing into it all at once during mixing, which would cause material stratification and dead corners.

[0025] like Figure 1 and Figure 3 As shown, the spray assembly 114 includes a liquid storage tank body 2; the liquid storage tank body 2 is installed on the side wall of the placement platform 1 away from the storage box 4; a conveying pipe 21 is fixedly connected to the top of the platform and passes through the stirring assembly 113; a connecting pipe 25 is detachably connected to the end of the conveying pipe 21; a third motor 22 is fixedly connected to the top of the stirring assembly 113 near the conveying pipe 21; a drive gear 24 is fixedly connected to the output end of the third motor 22; a driven gear 23 is fixedly connected to the middle of the connecting pipe 25 near the drive gear 24 and is in a meshing state with the drive gear 24; multiple equally spaced water outlet pipes 26 are fixedly connected to the middle of the connecting pipe 25 near the driven gear 23; During operation, when the raw materials enter the mixing assembly 113, the liquid additive pump in the middle of the storage tank body 2 is turned on. The pressure of the liquid additive pump can transport the liquid additive through the conveying pipe 21 to the middle of the chute 5. At this time, the third motor 22 is started. The output end of the third motor 22 drives the drive gear 24 and the mixing tank 3 to rotate, and synchronously drives the connecting pipe 25 to rotate. While rotating, the liquid additive can be sprayed out through the water outlet pipe 26 to contact the raw materials. Through the above structure, the liquid additive can be effectively dispersed evenly on the surface of the raw materials, accelerating the wetting of the raw materials and reducing the problem of water clumps or dry material accumulation caused by manual water addition or fixed-point spraying.

[0026] like Figure 1 and Figure 3 As shown, the mixing assembly 113 includes a mixing tank 3; a mixing rod 31 is fixedly connected to the top of the mixing tank 3; the end of the connecting pipe 25 away from the mixing rod 31 is fixedly connected to the mixing rod 31; a plurality of equidistantly distributed connecting rods 32 are fixedly connected to the middle of the mixing rod 31; a plurality of equidistantly distributed adjusting bolts 33 are detachably connected to the middle of the connecting rods 32; a mixing rod 34 is fixedly connected to the middle of the adjusting bolts 33; during operation, the connecting pipe 25 rotates simultaneously, driving the mixing rod 31 and the connecting rods 32 to rotate. The connecting rods 32 can cause the raw materials to gather towards the center of the mixing tank 3, while the mixing rods 34 can generate local strong shearing force to break up and disperse the clumps of raw materials. Through the above structure, the combined use of the connecting rods 32 and the mixing rods 34 can generate axial flow in the middle of the mixing tank 3, reducing problems such as slurry and sediment during mixing operations. Moreover, the adjustable position design increases the applicability of the device to meet different mixing needs.

[0027] like Figure 4As shown, the spray assembly 114 includes a storage box 4; the storage box 4 is fixedly connected to the bottom of the placement platform 1 near the storage tank body 11; a plurality of partitions 41 are fixedly connected to the middle of the storage box 4 in an equidistant manner; during operation, the partitions 41 can separate the space in the middle of the storage box 4 to form multiple storage spaces for placing different kinds of raw materials or additives, etc., increasing the convenience of the device. Through the above structure, the problems of raw materials and additives being scattered or wasted due to random placement can be effectively reduced, increasing the convenience for operators to pick them up and making the mixing operation smoother.

[0028] like Figure 4 As shown, the first sealing cover 12 has multiple equally spaced grooves 5 on its top near the first motor 13; a sliding rod 51 is slidably connected to the middle of the groove 5; during operation, the bottom of the sliding rod 51 contacts the surface of the raw material and slides up and down in the middle of the groove 5 as the height of the raw material is adjusted to determine whether the raw material is sufficient. Through the above structure, the status of the raw material can be fed back in real time, and the operator can directly determine whether the raw material is sufficient by the position of the sliding rod 51, thereby reducing problems such as imbalance in the raw material ratio.

[0029] like Figure 1 As shown, two symmetrically arranged shock-absorbing pads 6 are fixed to the bottom of the placement platform 1 near the mixing tank 3; the shock-absorbing pads 6 are made of rubber; during operation, the rubber shock-absorbing pads 6 can effectively absorb the vibration and noise generated during the operation of the device. Through the above structure, the wear of device parts caused by vibration can be effectively reduced, and the frequency of replacement of parts can be reduced.

[0030] like Figure 3 As shown, the middle part of the stirring assembly 113 is coated with a nano-hydrophobic coating. During operation, this coating can reduce the adhesion of raw materials to its surface when the stirring assembly 113 is stirring the raw materials. Through the above structure, the problem of reduced stirring efficiency caused by raw materials accumulating on the surface of the stirring assembly 113 can be effectively reduced.

[0031] During operation, the first sealing cover 12 is opened, and the sand and gravel raw materials are placed in the middle of the storage bin 15. At this time, the weight of the raw materials can press the top plate 18 downward. As the raw materials gradually decrease, the rebound force of the spring 17 can lift the top plate 18, and the guide groove 16 can limit it, allowing it to slide up and down in the middle of the storage bin 15. Then, the first motor 13 is started. The output end of the first motor 13 drives the rotating rod 14 and the storage bin 15 to rotate. When the raw materials in the middle of the storage bin 15 come into contact with the gravity flip door 112, the weight of the raw materials will push the gravity flip door 112 open, and then slide down to the top of the feed plate 19. At this time, the second motor 110 is started. The output end of the second motor 110 drives the scraper 111 to rotate, scraping the raw materials evenly to the middle of the stirring assembly 113 for stirring. After the raw materials enter the stirring assembly 113, the liquid additive pump in the middle of the liquid storage tank body 2 is turned on. The pressure of the liquid additive pump can transport the liquid additive through the conveying pipe 21 to the middle of the chute 5. When the third motor 22 is started, its output drives the drive gear 24 and the mixing tank 3 to rotate, and simultaneously drives the connecting pipe 25 to rotate. While rotating, the liquid additive can be sprayed out through the water outlet pipe 26 to contact the raw materials. When the connecting pipe 25 rotates, it will simultaneously drive the stirring rod 31 and the connecting rod 32 to rotate. The connecting rod 32 can make the raw materials gather towards the center of the mixing tank 3, while the stirring rod 34 can generate local strong shearing force to break up and disperse the clumps of raw materials. The partition 41 can divide the space in the middle of the storage box 4 to form multiple storage spaces for placing different kinds of raw materials or additives, etc., increasing the convenience of the device. The bottom of the slide rod 51 contacts the surface of the raw materials and slides up and down in the middle of the slide groove 5 according to the height of the raw materials to determine whether the raw materials are sufficient. The rubber shock-absorbing pad 6 can effectively absorb the vibration and noise generated during the operation of the device. This coating can reduce the adhesion of raw materials to the surface when the stirring component 113 stirs the raw materials.
