Description

Technical Field

[0001] The utility model relates to the technical field of mixers, and more specifically, to a building material mixer. Background Art

[0002] The definition of building materials involves all kinds of materials used in construction projects, including but not limited to cement, steel, wood, concrete, stone, brick lime, gypsum, building plastics, asphalt, glass and building ceramics. These materials play a fundamental and key role in construction, and there are many types of them. In general, the choice of building materials has an important impact on the quality, durability, beauty and environmental impact of the building.

[0003] A building material mixer is a type of engineering machinery specially used to mix building materials such as cement, sand, and various types of dry mortar to achieve uniform mixing. In general, a building material mixer is an indispensable part of construction machinery. Through its efficient mixing action, it ensures that the materials used in construction projects can meet construction requirements.

[0004] However, most of the existing mixers mix building materials by the rotation of the mixing rod. However, if only the rotation of the mixing rod is used, during the mixing process, due to the length and shape limitations of the mixing rod, it will not be able to cover all areas in the mixer, resulting in dead zones in some areas. The materials in these areas cannot be fully mixed, and different building materials have different physical and chemical properties, such as particle size, shape, humidity and viscosity. If only the rotation of the mixing rod is used, it may not be possible to overcome the mixing difficulties caused by these material properties, resulting in uneven mixing. The mixing speed and time will have a significant impact on the mixing effect. If only the rotation of the mixing rod is relied upon, it may take longer to achieve a uniform mixing effect, which will reduce the mixing efficiency. If uneven mixing occurs during the mixing of building materials, the strength of building materials such as concrete will be inconsistent, which will reduce the structural strength and durability of the entire building. In addition, uneven mixing will affect the construction quality, resulting in problems such as uneven surface and color differences, affecting the appearance and beauty of the building, and failing to meet the user's needs.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a building material mixer. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a building material mixer.

[0007] To achieve the above object, the utility model provides the following technical solution: a building material mixer, comprising a mixing barrel, a cover is slidably mounted at the feed inlet of the mixing barrel, a motor is mounted on the cover, a screw is plugged into the output end of the motor, an end of the screw away from the motor passes through the cover and extends into the mixing barrel, and also includes:

[0008] Multiple stirring components are arranged on the screw, each stirring component includes a screw sleeve, multiple screw sleeves are slidably installed on the screw at uniform intervals, a protection box is installed at the lower end of each screw sleeve, a sliding hole is opened in the middle of each protection box, multiple stirring rods are rotatably installed on each protection box at uniform intervals, one end of each stirring rod close to the protection box extends into the interior of the protection box, and a gear is inserted at the end of each stirring rod extending into the interior of the protection box, and a plurality of stirring blades are installed at equal intervals on the end of each stirring rod outside the protection box, and each stirring blade is opened with multiple through holes at equal intervals.

[0009] Preferably, each of the protection boxes is provided with a rotating assembly, each rotating assembly includes a support plate, each of the protection boxes is connected to a support plate at the lower end, the screw passes through the center of each support plate, each of the support plates can slide on the screw, and each of the support plates close to the protection box is provided with an annular rack, each of the protection boxes is communicated with the support plates close to each other, each of the gears is meshed with the annular racks close to each other, and each of the support plates is provided with a stopper at the lower end, so that when the gear rolls on the annular rack, the stirring rotation will be driven by the rotation of the gear. At this time, the stirring rod will follow the gear to rotate on the protection box, and the rotation of the stirring rod will drive the stirring blades to rotate, so as to achieve further uniform stirring of the building materials inside the mixing barrel, and the stopper and the screw sleeve are used to block the stirring blades from contacting each other during rotation, thereby causing damage to the stirring blades.

[0010] Preferably, each of the sliding holes is communicated with mutually adjacent screw sleeves, and the screw rod passes through each screw sleeve and each sliding hole at the same time, so that the protection box can move up and down smoothly on the screw rod, and the protection box and the screw sleeve can also achieve concentric rotation.

[0011] Preferably, each of the protection boxes can rotate on the connected support plate. When each of the protection boxes rotates on the support plate, the support plate will not rotate along with the connected protection box. Each of the support plates will only move vertically along with the connected protection box, so as to avoid the support plate and the annular rack from rotating along with the protection box. If the support plate and the annular rack rotate along with the protection box, the gear will rotate synchronously with the annular rack, which will cause the gear to be unable to roll on the annular rack. If the gear does not roll on the annular rack, the stirring rod will not be able to rotate on its own.

[0012] Preferably, a plurality of supporting legs are installed at equal intervals on the lower end of the mixing barrel to provide stability to the mixing barrel when the mixing barrel is working.

[0013] Preferably, a support block is installed in a mirror image on the outer side of the mixing barrel, and an electric telescopic rod is installed on each of the support blocks. A connecting plate is installed in a mirror image on the outer side of the lid, and the telescopic end of each electric telescopic rod is connected to the connecting plates close to each other, so that the lid can be moved vertically by the electric telescopic rod, thereby realizing the opening and closing of the mixing barrel.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, each stirring assembly arranged on the screw rod will drive the screw sleeve to move up and down and rotate on the screw rod through the rotation of the screw rod. When the screw sleeve moves and rotates, it will move and rotate the protection box with it. The rotation and up and down movement of the protection box will drive the stirring rod to move up and down and rotate. When each stirring rod rotates and moves, it will drive the gear and the stirring blade to move up and down and rotate. At this time, the stirring rod and the stirring blade repeatedly move up and down inside the mixing barrel and follow the rotation of the screw sleeve, so as to achieve uniform stirring of the building materials inside the mixing barrel. At the same time, when the stirring blade is rotating, the stirring blade passes through the through hole to reduce the resistance during stirring, thereby solving the problem in the background technology that if the building materials are stirred, uneven stirring will cause inconsistent strength of building materials such as concrete, which will reduce the structural strength and durability of the entire building. In addition, uneven stirring will affect the construction quality, resulting in problems such as uneven surface and color difference, affecting the appearance and beauty of the building, and failing to meet the user's use needs.

[0016] 2. In the utility model, each rotating assembly arranged at the lower end of the protection box will move up and down and rotate through the protection box, and the support plate will move up and down with the protection box at this time, and the protection box will rotate on the support plate at the same time. When the protection box rotates on the support plate, the stirring rod rotating with the protection box will roll on the annular rack with the gear. When the gear rolls on the annular rack, the stirring rod will be driven to rotate by the rotation of the gear. At this time, the stirring rod will rotate on the protection box following the gear, and the rotation of the stirring rod will drive the stirring blade to rotate. At the same time, when the support plate moves up and down, the stopper will also move up and down with the support plate, so that the stirring rod and the stirring blade can also rotate on the protection box when following the rotation of the screw, which can effectively further evenly stir the building materials inside the mixing barrel, and can also avoid when a certain screw sleeve rotates too fast or too slow on the screw. The stopper and the screw sleeve are used to block it, which can effectively avoid the stirring blades from contacting each other during rotation, thereby avoiding damage caused by contact between the stirring blades.

DETAILED DESCRIPTION

[0023] like Figure 1-4As shown, the utility model provides a building material mixer, including a mixing barrel 1, which is used to contain and store materials to be mixed. A cover 6 is slidably installed at the feed inlet of the mixing barrel 1, which is used to prevent the building materials from splashing out of the mixing barrel 1 when the building materials are mixed. A motor 7 is installed on the cover 6, which is used to provide power to a screw 8. The output end of the motor 7 is plugged with a screw 8, which is used to realize the up and down movement of a screw sleeve 901 through the rotation of the screw 8. The end of the screw 8 away from the motor 7 passes through the cover 6 and extends into the mixing barrel 1. It also includes:

[0024] A plurality of stirring components 9 are arranged on the screw 8, and are used for realizing radical up and down repeated movement and rotation of the stirring components 9 on the screw 8, so as to achieve uniform stirring of the building materials inside the mixing barrel 1. Each stirring component 9 includes a screw sleeve 901, and a plurality of screw sleeves 901 are slidably installed on the screw 8 at uniform intervals, and are used for realizing that the connected protection box 902 is driven by the screw sleeve 901 to move up and down. A protection box 902 is installed at the lower end of each screw sleeve 901, and is used for supporting the stirring rod 905 and preventing the gear 904 and the annular rack 1002 from contacting with the building materials, so as to achieve the purpose of extending the service life of the gear 904 and the annular rack 1002. A sliding hole 903 is opened in the middle of each protection box 902, and each sliding hole 903 is communicated with the screw sleeves 901 close to each other. The screw 8 passes through each screw sleeve 901 and each sliding hole 903 at the same time, and is used for realizing that the protection box 902 can move up and down smoothly on the screw 8. The invention can not only realize the movement of the stirring rod 905, but also realize the concentric rotation of the protection box 902 and the screw sleeve 901. A plurality of stirring rods 905 are evenly spaced and rotated on each protection box 902, which are used to realize the support gear 904 and the stirring blade 906, and have a transmission function. One end of each stirring rod 905 close to the protection box 902 extends into the interior of the protection box 902, and one end of each stirring rod 905 extending into the interior of the protection box 902 is plugged with a gear 904, which is used to realize the rolling of the stirring rod 905 on the annular rack 1002 through the gear 904 to drive the stirring rod 905 to rotate. A plurality of stirring blades 906 are evenly spaced and installed on one end of each stirring rod 905 outside the protection box 902, which are used to stir the building materials inside the mixing barrel 1, and a plurality of through holes 907 are evenly spaced on each stirring blade 906, which are used to realize that when the stirring blade 906 is rotating, the stirring blade 906 passes through the through hole 907 to reduce the resistance during stirring.

[0025] The lower end of each protection box 902 is provided with a rotating assembly 10, which is used to realize that when the gear 904 rolls on the annular rack 1002, the gear 904 will drive the stirring rotation through the rotation of the gear 904. At this time, the stirring rod 905 will follow the gear 904 to rotate on the protection box 902. At the same time, the rotation of the stirring rod 905 will drive the stirring blade 906 to rotate, so as to achieve further uniform stirring of the building materials inside the mixing barrel 1, and the stopper 1003 and the screw sleeve 901 are used to block it to prevent the stirring blades 906 from contacting each other during rotation, thereby causing In order to prevent the stirring blade 906 from being damaged, each rotating assembly 10 includes a support plate 1001, and each protection box 902 is connected to a support plate 1001 at the lower end, which is used to achieve the supporting function. Each protection box 902 can rotate on the connected support plate 1001. When each protection box 902 rotates on the support plate 1001, the support plate 1001 will not rotate with the connected protection box 902. Each support plate 1001 will only move vertically with the connected protection box 902, which is used to prevent the support plate 1001 and the annular rack 1002 from following the protection box 902. The box 902 rotates together. If the support plate 1001 and the annular rack 1002 rotate with the protection box 902, the gear 904 will rotate synchronously with the annular rack 1002, which will cause the gear 904 to be unable to roll on the annular rack 1002. If the gear 904 does not roll on the annular rack 1002, the stirring rod 905 will not be able to rotate on its own. The screw 8 passes through the center of each support plate 1001, which is used to ensure that the support plate 1001 rotates concentrically with the protection box 902. Each support plate 1001 can slide on the screw 8. A ring rack 1002 is installed on one side of each support plate 1001 close to the protection box 902, which is used to facilitate the gear 904 to roll on the ring rack 1002, so that the stirring rod 905 can rotate. Each protection box 902 is communicated with the support plates 1001 close to each other, and each gear 904 is meshed with the ring racks 1002 close to each other, which is used to facilitate the gear 904 to roll on the ring rack 1002. A stopper 1003 is installed at the lower end of each support plate 1001, which is used to prevent the stirring rod 905 and the stirring blade 906 from contacting each other.

[0026] A plurality of support legs 2 are installed at equal intervals at the lower end of the mixing barrel 1, which are used to provide stability during mixing. A support block 3 is installed in a mirror image on the outer side of the mixing barrel 1, and an electric telescopic rod 4 is installed on each support block 3. A connecting plate 5 is installed in a mirror image on the outer side of the cover 6, and the telescopic end of each electric telescopic rod 4 is connected to the connecting plates 5 close to each other, which is used to realize the opening and closing of the mixing barrel 1 by moving the cover 6.

[0027] Working principle: first start the motor 7, and the motor 7 drives the screw 8 to rotate. The rotation of the screw 8 will drive the screw sleeve 901 to move up and down and rotate on the screw sleeve 8. When the screw sleeve 901 moves and rotates, it will move the protection box 902 and follow the rotation of the screw sleeve 901. The rotation and up and down movement of the protection box 902 will drive the stirring rod 905 to move up and down and follow the rotation of the protection box 902. When each stirring rod 905 rotates and moves, it will move the gear 904 and the stirring blade 906 up and down and rotate. At this time, the stirring rod 905 and the stirring blade 906 repeatedly move up and down inside the mixing barrel 1 and follow the rotation of the screw sleeve 901, so as to achieve uniform stirring of the building materials inside the mixing barrel 1. At the same time, when the stirring blade 906 is rotating, the stirring blade 906 passes through the through hole 907 to reduce the resistance during stirring. When the protection box 902 is moving up and down and rotating, the support plate 1001 will follow the protection box 902 to move up and down. At this time The protection box 902 will rotate on the support plate 1001 at the same time. When the protection box 902 rotates on the support plate 1001, the stirring rod 905 that rotates with the protection box 902 will roll on the ring rack 1002 with the gear 904. When the gear 904 rolls on the ring rack 1002, the stirring will be driven by the rotation of the gear 904. At this time, the stirring rod 905 will rotate on the protection box 902 following the gear 904. The rotation will drive the stirring blades 906 to rotate, so as to achieve further uniform stirring of the building materials inside the mixing barrel 1. At the same time, when the support plate 1001 moves up and down, the block 1003 will also move up and down with the support plate 1001, so as to achieve the situation that when a certain screw sleeve 901 rotates too fast or too slow on the screw rod 8, it is blocked by the block 1003 and the screw sleeve 901 to prevent the stirring blades 906 from contacting each other during rotation, thereby causing damage to the stirring blades 906.
