Description
Technical Field
[0001] The utility model relates to the technical field of building material mixing devices, and particularly relates to a building material mixing device. Background Art
[0002] Concrete refers to cement concrete, also known as ordinary concrete, which is made by using cement as a binder, sand and stone as aggregates, and mixing with water (which may contain additives and admixtures) in a certain proportion. It is widely used in construction projects. During use, workers usually need to use a mixing device to mix and stir concrete materials.
[0003] In traditional technologies, the designed concrete mixing devices usually include a mixing barrel and a mixing blade assembly for mixing the materials in the mixing barrel. The mixing barrel is usually vertically arranged and fixed. Due to the action of the material weight, the materials are concentrated at the bottom of the mixing barrel, and the materials at the top of the mixing barrel are difficult to be fully mixed. Summary of the Utility Model
[0004] In order to solve the above problems, the utility model provides a building material mixing device.
[0005] The above technical purpose of the utility model is achieved by the following technical solutions: a building material mixing device, including a bottom plate, a fixed block fixed to the top of the bottom plate, a horizontal mixing barrel arranged on the bottom plate, a mounting rack fixed to the top of the bottom plate, and a feeding hopper arranged on the mounting rack and used for adding materials into the horizontal mixing barrel. A central rod extending into the horizontal mixing barrel is rotatably installed on the fixed block. A plurality of mixing rods are fixed on the central rod. A driving mechanism for driving the central rod and the horizontal mixing barrel to rotate in opposite directions is arranged on the fixed block.
[0006] By adopting the above technical solutions, the materials in the horizontal mixing barrel are concentrated and distributed at the bottom of the horizontal mixing barrel. The driving mechanism drives the central rod and the horizontal mixing barrel to rotate in opposite directions, so that the mixing rods fully mix the materials in the horizontal mixing barrel, improving the mixing effect of the building materials.
[0007] Furthermore, an installation plate is fixed on the bottom plate. The horizontal mixing barrel is rotatably connected to the installation plate through a bearing.
[0008] Furthermore, the driving mechanism includes a gear ring fixedly sleeved on the horizontal mixing barrel, a transmission wheel fixed on the central rod, and a motor fixed on the fixed block. The end of the output shaft of the motor penetrates through the fixed block and is rotatably connected. The driving mechanism also includes a driving wheel fixedly sleeved on the output shaft of the motor, a transmission belt for connecting the driving wheel and the transmission wheel, and a driving gear fixed to the end of the output shaft of the motor and meshing with the gear ring.

The driving wheel drives the driven wheel, the central rod fixed to the driven wheel, and the stirring rod fixed to the central rod to rotate through the transmission belt. The driving gear drives the gear ring and the horizontal stirring barrel fixed to the gear ring to rotate, and the stirring rod rotates in the opposite direction to the horizontal stirring barrel, so that the materials in the horizontal stirring barrel are fully stirred, improving the mixing quality of the building materials.
[0010] Further, the horizontal stirring barrel includes a first barrel body and a second barrel body. The first barrel body and the second barrel body together form a cylindrical structure. A spindle-shaped first stirring chamber is arranged in the first barrel body, and a second stirring chamber is arranged in the second barrel body. The inner diameter of the second stirring chamber increases from the middle of the second barrel body to both sides.
[0011] Both sides of the first barrel body are fixedly connected with first connecting plates, and both sides of the second barrel body are fixedly connected with second connecting plates. The first connecting plates and the second connecting plates are fixedly connected by bolts and nuts.
[0012] By adopting the above technical solution, the first barrel body and the second barrel body are spliced into a horizontal stirring barrel, which is convenient for the staff to repair or replace the parts in the horizontal stirring barrel. The limitation on the shapes of the first stirring chamber and the second stirring chamber enables the middle materials and the materials on both sides in the horizontal stirring barrel to be in a flowing state all the time, which is beneficial to fully improving the stirring effect of the materials.
[0013] Further, a discharge pipe is fixedly connected and communicated with the middle of the first barrel body, and a solenoid valve is arranged on the discharge pipe.
[0014] By adopting the above technical solution, when the discharge pipe rotates to the lower part of the horizontal stirring barrel, the solenoid valve can be opened to discharge the materials in the horizontal stirring barrel.
[0015] Further, a sealing rubber plate is arranged between the first barrel body and the second barrel body.
[0016] By adopting the above technical solution, the sealing rubber plate enhances the sealing performance of the horizontal stirring barrel formed by the first barrel body and the second barrel body during use.
[0017] Further, the motor is a servo motor.
[0018] By adopting the above technical solution, it is convenient for the staff to control the speed, start and stop of the motor, so as to control the material stirring work.
[0019] Further, a rotary shaft seal for rotary sealing is arranged between one end of the horizontal stirring barrel and the discharge end of the feeding hopper.
[0020] By adopting the above technical solution, the rotation shaft seal is arranged, so that while maintaining relative rotation between one end of the horizontal stirring barrel and the discharge end of the feeding hopper, good sealing performance is achieved, and the probability of leakage of the materials in the horizontal stirring barrel can be effectively reduced.
[0021] In summary, the present utility model has the following beneficial effects:
[0022] 1. In this application, the materials in the horizontal stirring barrel are concentrated and distributed at the bottom of the horizontal stirring barrel. The driving mechanism drives the central rod to rotate in the opposite direction to the horizontal stirring barrel, so as to enable the stirring rod to fully stir the materials in the horizontal stirring barrel, improving the mixing effect of building materials;
