Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, and particularly relates to a large-particle material mixing station. Background Art

[0002] The cementitious sand and gravel dam is a new dam-building technology developed internationally in recent years. It is a new dam type developed on the basis of the face slab dam and the roller compacted concrete gravity dam. The cementitious sand and gravel dam-building material can be formed by mixing aggregate, cementitious material, water, and admixture through a large-particle material mixing station. Moreover, the sand and gravel washed and accumulated in the riverbed and the excavated material of the dam foundation can be used after simple screening, with low requirements for aggregate, and local materials can be used on the spot.

[0003] After being stirred by the mixing station, the mixed material will enter the transport vehicle through the discharge port at the bottom of the mixing station. When the mixed material passes through the discharge port, it is inevitable that some will adhere to the discharge port. Usually, it is not obvious when the mixed material continuously falls from the discharge port. After the mixed material stops falling, some of the mixed material adhering to the side wall of the discharge port will dry and solidify. Although it will not block the discharge port, it will affect the flow rate of the discharge port. Therefore, it is necessary for the staff to manually remove the dried and solidified mixed material. When removing it, the staff needs to stand under the discharge port, which makes the dried material falling from the discharge port directly fall on the staff, not only difficult to clean, but also causing a burden on the staff's body.

[0004] Therefore, we propose a large-particle material mixing station to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that it is difficult to automatically remove the dried material condensed on the side wall of the discharge port in the prior art, and to propose a large-particle material mixing station.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A large-particle material mixing station includes a mixing station body. Two discharge ports are opened at the bottom of the mixing station body. Two sliding grooves are respectively opened on the side walls of both sides of the discharge ports. Two telescopic plates are respectively slidably connected in the two sliding grooves. The two telescopic plates are fixedly connected together at one end far away from the sliding grooves with a bottom plate. A servo motor is embedded in the bottom plate. A central shaft is arranged at the output end of the servo motor. A cleaning rod is fixedly connected to the side wall of the central shaft. Two control mechanisms for controlling the telescopic movement of the telescopic plates are respectively arranged between the output end of the servo motor and the two telescopic plates.

[0008] Preferably, the telescopic plate includes an outer plate and an inner plate. The outer plate slides in the sliding groove, and the inner plate extends into the outer plate and is fixedly connected to the bottom plate at the other end.

[0009] Preferably, the control mechanism includes a driving wheel, a rotating wheel, a telescopic rod, a reciprocating lead screw and a moving block. The driving wheel is fixedly connected to the output end of the servo motor. An inner cavity is formed in the inner plate, and an outer cavity is formed in the outer plate. The inner cavity communicates with the outer cavity. The telescopic rod is rotatably connected to the bottom wall of the inner cavity, and the rotating wheel is fixedly connected to the side wall of the telescopic rod. The driving wheel and the rotating wheel are driven by a belt. One end of the reciprocating lead screw is rotatably connected to the top wall of the outer cavity, and the other end is fixedly connected to the top of the telescopic rod. The moving block is fixedly installed on the side wall of the inner cavity, and the moving block is sleeved outside the reciprocating lead screw.

[0010] Preferably, a baffle is fixedly installed at the bottom end of the reciprocating lead screw.

[0011] Preferably, the longitudinal section of the cleaning rod is "L" shaped, and the length of the long end of the cleaning rod is consistent with the inner diameter of the discharge port.

[0012] Preferably, the outer diameter of the baffle is larger than the outer diameter of the reciprocating lead screw.

[0013] In summary, the technical effects and advantages of the present utility model are as follows:

[0014] By arranging an outer plate, an inner plate, a bottom plate, a servo motor, a central shaft, a cleaning rod, a driving wheel, a rotating wheel, a telescopic rod, a reciprocating lead screw and a moving block near the discharge port, the staff can control the servo motor to make the inner plate automatically move up and down reciprocally along the direction of the outer plate, so as to more comprehensively remove the dry materials on the inner wall of the discharge port. At the same time, when cleaning is not required, the outer plate and the inner plate can also be slid along the chute to one side of the discharge port to avoid affecting the normal discharge of the discharge port.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] As Figure 1 shown in Figure 2 the figure, a large particle material mixing station includes a mixing station body 1. Two discharge ports 2 are opened at the bottom of the mixing station body 1. Two sliding grooves 3 are respectively opened on the side walls of both sides of the discharge port 2. Two sliding grooves 3 are provided on both sides of each discharge port 2, and the distances from the two sliding grooves 3 to the discharge port 2 are also the same. Two telescopic plates are respectively slidably connected in the two sliding grooves 3. The two telescopic plates are fixedly connected to a bottom plate 4 at one end away from the sliding grooves 3. The telescopic plate includes an outer plate 8 and an inner plate 9. The outer plate 8 slides in the sliding groove 3, the inner plate 9 extends into the outer plate 8, the size of the inner plate 9 is smaller than that of the outer plate 8, and the other end is fixedly connected to the bottom plate 4.

[0021] A servo motor 5 is embedded in the bottom plate 4. A central shaft 6 is installed at the output end of the servo motor 5. A cleaning rod 7 is fixedly connected to the side wall of the central shaft 6. The longitudinal section of the cleaning rod 7 is "L" shaped, and the length of the long end of the cleaning rod 7 is the same as the inner diameter of the discharge port 2. When the servo motor 5 is driven to be directly below the discharge port 2, the upward movement of the servo motor 5 will make the side wall of the cleaning rod 7 abut against the side wall of the discharge port 2, thereby facilitating the cleaning of the inner wall of the discharge port 2.

[0022] Referring to Figure 3 the figure, two control mechanisms for controlling the telescopic movement of the telescopic plates are respectively installed between the output end of the servo motor 5 and the two telescopic plates. The control mechanism includes a driving wheel 10, a rotating wheel 11, a telescopic rod 12, a reciprocating screw rod 13 and a moving block 14. The driving wheel 10 is fixedly connected to the output end of the servo motor 5. As Figure 2 can also be seen from the figure, there are two driving wheels 10 at the output end of the servo motor 5, which are respectively belt-driven with the rotating wheels 11 in the two inner plates 9. An inner cavity is opened in the inner plate 9, and an outer cavity is opened in the outer plate 8. The inner cavity is communicated with the outer cavity, and the size of the outer cavity is also larger than that of the inner plate 9. Therefore, the inner plate 9 can completely enter the outer cavity, and the telescopic rod 12 is rotatably connected to the bottom wall of the inner cavity.

[0023] The rotating wheel 11 is fixedly connected to the side wall of the telescopic rod 12. The driving wheel 10 and the rotating wheel 11 are driven by a belt. A perforation is provided on the side wall of the inner plate 9, so that the belt can enter the inner plate 9. The driving wheel 10 drives the rotating wheel 11 to rotate together. One end of the reciprocating lead screw 13 is rotatably connected to the top wall of the outer cavity, and the other end is fixedly connected to the top of the telescopic rod 12. A baffle 15 is fixedly installed at the bottom end of the reciprocating lead screw 13. The outer diameter of the baffle 15 is larger than that of the reciprocating lead screw 13. The setting of the baffle 15 can prevent the moving block 14 from completely disengaging from the reciprocating lead screw 13, thereby ensuring that the cleaning rod 7 can stably remove the dry material on the inner wall of the discharge port 2. The moving block 14 is fixedly installed on the side wall of the inner cavity, and the moving block 14 is sleeved outside the reciprocating lead screw 13.

[0024] The working principle is as follows: When it is necessary to remove the dry material on the inner wall of the discharge port 2, the staff can push the bottom plate 4 along the direction of the chute 3 to the directly below of the discharge port 2, and then start the servo motor 5. The rotation of the servo motor 5 will cause the two driving wheels 10 to rotate together. The rotation of the driving wheel 10 will drive the rotating wheel 11 to rotate. The telescopic rod 12 fixedly connected to the rotating wheel 11 will rotate accordingly, and then drive the reciprocating lead screw 13 to rotate. The moving block 14 sleeved on the reciprocating lead screw 13 will drive the inner plate 9 to move up and down reciprocally along the direction of the outer plate 8. At the same time, the rotation of the servo motor 5 can also drive the central shaft 6 and the cleaning rod 7 to rotate. Since the bottom plate 4 will move up and down reciprocally driven by the reciprocating lead screw 13, the cleaning rod 7 can also reciprocally clean the inner wall of the discharge port 2, achieving a better cleaning effect.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
