Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a permeable concrete raw material mixing device. Background Art

[0002] Permeable concrete is a special type of concrete with high water permeability, which allows water to penetrate through its surface into the groundwater layer, playing a role in drainage and environmental protection.

[0003] The permeable concrete raw material mixing device is a device used to fully mix the raw materials of permeable concrete. Its main functions include raw material mixing, mixing quality control, improving production efficiency, saving manpower and material resources, and ensuring the quality of permeable concrete, so as to meet the needs and requirements of the project. Since the mixing methods of existing permeable concrete raw material mixing devices are mostly relatively single, the stirring rod of the mixing device has a small contact range with the raw materials inside the mixing device when it rotates, which leads to low mixing efficiency and reduces production efficiency. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide a permeable concrete raw material mixing device, which can effectively solve the problem of low mixing efficiency of the existing permeable concrete raw material mixing device.

[0005] In order to solve the above problems, the technical solution of the utility model is:

[0006] A permeable concrete raw material mixing device comprises a cylinder and a stirring mechanism, wherein a motor is arranged at the center of the outer top surface of the cylinder.

[0007] The stirring mechanism includes a rotating drum, a vertical rod and a stirring rod. The outer top surface of the rotating drum is fixedly connected to the output shaft of the motor. The rotating drum is provided with a plurality of vertical strip holes equidistantly along the length direction. The vertical rod is located in the rotating drum, and the lower end extends out of the rotating drum and is fixedly connected to the cylinder body. The vertical rod is provided with a plurality of grooves corresponding to the strip holes on the rotating drum, and the grooves are corrugated grooves surrounding the peripheral wall of the vertical rod. A shell is provided for the sliding sleeve on the outside of the rotating drum, and a plurality of cross bars corresponding to the strip holes on the rotating drum are fixedly connected to the inner wall of the shell, and the free end of each cross bar passes through the corresponding strip hole and extends into the corresponding groove. The cross bar slides up and down along the strip hole, and a stirring rod is provided on the outer wall of the shell.

[0008] The utility model has a simple structure. By arranging a plurality of strip holes on the rotating drum and corrugated grooves on the vertical rods, when the motor rotates, the cross bar can be driven by the undulating corrugations on the corrugated grooves to move up and down along the strip holes, thereby achieving up and down reciprocating motion of the stirring rod, and forming oscillating stirring of the concrete raw materials in the cylinder in the up and down directions. The stirring efficiency of the utility model is greatly improved, the stirring time is effectively shortened, and good economic benefits are achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0014] like Figure 1-Figure 3 As shown, a permeable concrete raw material mixing device includes a cylinder 1 and a stirring mechanism. The cylinder 1 is a cylinder, and a motor 2 is provided at the center of the outer top surface of the cylinder 1.

[0015] The stirring mechanism includes a drum 3, a vertical rod 4 and a stirring rod 8. The drum 3 is a hollow cylinder with closed upper and lower ends. The outer top surface of the drum 3 is fixedly connected to the output shaft of the motor 2. The drum 3 is provided with a plurality of vertical strip holes 13 equidistantly along the length direction of the peripheral wall. The vertical rod 4 is located in the drum 3, and the lower end extends out of the drum 3 and is fixedly connected to the cylinder body 1. The vertical rod 4 is a cylinder, and a gap is left between the top of the vertical rod 4 and the inner top surface of the drum 3. The vertical rod 4 is provided with a plurality of grooves 5 equidistantly along the length direction of the peripheral wall, corresponding to the strip holes on the drum 3. The grooves 5 are corrugated grooves surrounding the peripheral wall of the vertical rod 4. The outer sliding sleeve of the drum 3 A shell body 6 is provided, which is a hollow cylinder with closed upper and lower ends. A gap is left between the top of the shell body 6 and the inner top surface of the cylinder body 1. A plurality of cross bars 7 corresponding to the strip holes 13 on the rotating drum 3 are fixedly connected to the inner wall of the shell body 6 at equal intervals along the length direction. The cross bars 7 are round rods with a diameter corresponding to the width of the strip holes 13. The free end of each of the cross bars 7 passes through the corresponding strip hole 13 and extends into the corresponding groove 5. The shell body 6 is slid up and down on the outside of the rotating drum 3 through the cross bars 7. The free end of the cross bar 7 is in sliding contact with the groove 5. The cross bar 7 is in an up and down sliding state along the strip hole 13. A stirring rod 8 is provided on the outer wall of the shell body 6.

[0016] A feed hopper 11 connected to the interior of the cylinder 1 is disposed on the top plate of the cylinder 1 . The feed hopper 11 is an inverted hollow truncated cone with openings at both ends.

[0017] A plurality of support rods 9 are fixedly connected to the peripheral wall of the lower portion of the vertical rod 4 . The support rods 9 are rectangular rod bodies, and the other ends of the support rods 9 are fixedly connected to the lower portion of the inner wall of the cylinder body 1 .

[0018] A discharge door 14 is provided at the center of the bottom plate 10 of the cylinder 1 .

[0019] The bottom plate 10 is in an arc shape with a protrusion facing downward.

[0020] The bottom plate 10 of the cylinder 1 enables the raw materials to flow to the discharge gate 14 due to the height difference when they reach the bottom of the cylinder 1, making it more convenient to discharge the raw materials after mixing.

[0021] A plurality of supporting legs 12 are vertically connected to the bottom surface of the cylinder 1 .

[0022] A plurality of groups of stirring rods are arranged on the outer wall of the shell 6 from top to bottom at intervals, and each group of stirring rods is composed of a plurality of stirring rods 8 arranged along the central axis of the shell 6, and the stirring rods 8 are round rods.

[0023] When in use, after the raw materials are put into the feed hopper 11, the motor 2 is started, and the motor 2 drives the rotating drum 3 to rotate. When the rotating drum 3 rotates, the strip holes 13 on the rotating drum 3 rotate accordingly, and the cross bar 7 is driven by the strip holes 13 to rotate accordingly, so that the shell 6 rotates, and then the multiple stirring rods 8 fixedly connected to the shell 6 rotate to perform mixing work. During the rotation of the cross bar 7, since the free end of the cross bar 7 extends into the corrugated groove 5, the cross bar 7 will be pressed by the top surface or bottom surface of the corrugated groove 5 when rotating, and move up and down. When the cross bar 7 moves up and down along the strip holes 13, the shell 6 will also move upward or downward, so that the shell 6 drives the stirring rod 8 to move up and down while rotating. Therefore, while the stirring rod stirs the raw materials with the circumferential rotation of the shell 6, the upward or downward movement can contact the raw materials more, and can drive the raw materials to flip upward or downward, so as to promote faster mixing of the raw materials. The utility model solves the problem of low mixing efficiency of the existing permeable concrete raw material mixing device.

[0024] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Without violating the spirit of the present invention, that is, the disclosure scope, any multiple equivalent or equivalent deformations or replacements of the technical solutions of the utility model shall fall within the protection scope of the present invention.
