Description

Technical Field

[0001] This utility model relates to the technical field of material mixing, specifically a sand mixer with screening function. Background Technology

[0002] A sand mixer is an industrial equipment specifically designed for mixing materials. It is widely used in casting, building materials, metallurgy and other fields. Its core function is to uniformly mix different raw materials through mechanical action and adjust the physical properties of the materials to meet the needs of subsequent production. It is now widely used.

[0003] Existing sand mixers generally mix materials by injecting them into a mixing container and then using a mixing device. Some also use grinding wheels and discs to apply force to the materials, physically crushing and shearing them to break up particles and promote mixing. During the mixing process, the materials can be further crushed. However, this process often carries large pieces of sand and gravel, which can affect the mixing effect. Therefore, some mixers pre-screen the materials.

[0004] For example, a sand mixer with screening function, authorized by announcement number CN221107821U, adopts the above-mentioned method by adding a screen to screen the material before mixing. However, this device is in an open state during screening and mixing, especially during screening, where the screen is located at the feed point. Dust can easily be dispersed into the air during operation, causing harm to people. Therefore, we provide a sand mixer with screening function to solve the above problems. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This utility model proposes a sand mixer with a screening function. By setting up components such as a dustproof plate and a rotating plate, the material is poured into the upper part of the dustproof plate. After the material moves downward into the inside of the feeding cylinder, the dustproof plate is reset by the action of the upward pulling mechanism, thereby sealing the feeding cylinder and achieving the dustproof effect. When material needs to be fed, the power mechanism drives the rotating plate to rotate. The material entering the cavity inside the rotating plate follows the rotation. When the material moves to the position of the round hole on the lower fixed plate, it is fed downward, thus forming a second dustproof layer. This prevents dust from flying upward to the outside during screening below, achieving the effect of preventing dust from flowing to the outside. This solves the problem that dust easily disperses into the air during operation and causes harm to the human body.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a sand mixer with a screening function, comprising a sand mixer body, a fixed shell fixedly installed on the upper part of the sand mixer body, an upper fixed plate and a lower fixed plate fixedly connected to the inner wall of the fixed shell, a rotatable rotating plate slidably connected between the upper fixed plate and the lower fixed plate; a power mechanism is provided above the rotating plate, and a screening mechanism is provided below the rotating plate; a feed cylinder is fixedly connected to the upper surface of the upper fixed plate, an upward pulling mechanism is provided at the upper end of the feed cylinder, and a dustproof plate is provided at the lower part of the upward pulling mechanism, the dustproof plate being located inside the feed cylinder and in contact with it.

[0009] Furthermore, the power mechanism includes an electric motor, which is fixedly mounted on the upper surface of the upper fixed plate. The output end of the electric motor is fixedly connected to a transmission rod, and the lower end of the transmission rod passes through the upper fixed plate and is fixedly connected to the rotating plate.

[0010] Furthermore, the screening mechanism includes a filter plate, the outer surface of which is fixedly connected to the fixed shell, and two vibration motors are installed at the lower part of the filter plate.

[0011] Furthermore, a rotating rod is fixedly connected to the lower surface of the rotating plate, and the rotating rod passes through the lower fixed plate and is fixedly connected to multiple stirring rods at the lower part.

[0012] Furthermore, the pull-up mechanism includes a fixed cylinder, and a movable rod is slidably connected to the inner wall of the fixed cylinder. The lower end of the movable rod is fixedly connected to the dustproof plate.

[0013] Furthermore, a tension spring is provided inside the fixed cylinder, with the upper end of the tension spring fixedly connected to the inner top wall of the fixed cylinder and the lower end of the tension spring fixedly connected to the movable rod.

[0014] Furthermore, a support rod is fixedly connected to the outer surface of the fixed cylinder, and the end of the support rod away from the fixed cylinder is fixedly connected to the feed cylinder.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this sand mixing machine with screening function has the following advantages:

[0017] I. This sand mixer with screening function, through the setting of dustproof plates and rotating plates, etc., pours the material into the upper part of the dustproof plate. After the material moves downward into the inside of the feed cylinder, the dustproof plate is reset by the action of the upward pulling mechanism, thereby sealing the feed cylinder and achieving the dustproof effect. When material needs to be discharged, the power mechanism drives the rotating plate to rotate. The material entering the cavity inside the rotating plate follows the rotation. When the material moves to the position of the round hole on the lower fixed plate, it is fed downward, thus forming a second dustproof layer. This prevents dust from flying upward to the outside during screening below, thus achieving the effect of preventing dust from flowing to the outside. This solves the problem that dust easily floats into the air during operation and causes harm to the human body.

[0018] II. This sand mixer with screening function uses a screening mechanism and other components, and a vibrating motor to drive the filter plate to vibrate, thereby screening the material above the filter plate. The screened material falls into the interior of the lower sand mixer body for mixing. Larger materials remain on the top of the filter plate. One side of the fixed shell is equipped with an openable opening plate. After use, larger materials can be removed. When the rotating plate rotates, it can drive multiple stirring rods to rotate, flattening the material on the top of the filter plate for auxiliary screening and to increase the screening effect.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The electric motor 601 in this utility model is a common electrical device in the prior art, and this application will not elaborate on its model or internal structure.

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a sand mixer with screening function, including a sand mixer body 1, a fixed shell 2 fixedly installed on the upper part of the sand mixer body 1, an upper fixed plate 3 and a lower fixed plate 4 fixedly connected to the inner wall of the fixed shell 2, and a rotatable rotating plate 5 slidably connected between the upper fixed plate 3 and the lower fixed plate 4; a power mechanism 6 is provided above the rotating plate 5, and a screening mechanism 7 is provided below the rotating plate 5; a feed cylinder 8 is fixedly connected to the upper surface of the upper fixed plate 3, an upward pulling mechanism 9 is provided at the upper end of the feed cylinder 8, and a dustproof plate 10 is provided at the lower part of the upward pulling mechanism 9. The dustproof plate 10 is located inside the feed cylinder 8 and in contact with it. A circular hole is opened on the upper fixed plate 3 near the feed cylinder 8, and a circular hole is opened on the lower fixed plate 4 away from the feed cylinder 8. Six circular cavities of the same diameter are opened on the rotating plate 5. The rotating plate 5 has a certain thickness, and the power mechanism 6 can drive the rotating plate 5 to rotate.

[0029] The power mechanism 6 includes an electric motor 601, which is fixedly mounted on the upper surface of the upper fixed plate 3. The output end of the electric motor 601 is fixedly connected to a transmission rod 602. The lower end of the transmission rod 602 passes through the upper fixed plate 3 and is fixedly connected to the rotating plate 5. The electric motor 601 can drive the transmission rod 602 to rotate, thereby driving the rotating plate 5 to rotate.

[0030] The screening mechanism 7 includes a filter plate 701. The outer surface of the filter plate 701 is fixedly connected to the fixed shell 2. Two vibration motors 702 are installed at the lower part of the filter plate 701. The vibration motors 702 drive the filter plate 701 to vibrate, thereby screening the material above the filter plate 701. The screened material falls into the interior of the lower sand mixer body 1 for mixing. Larger materials remain above the filter plate 701. A door that can be opened is provided on one side of the fixed shell 2. After use, larger materials can be removed.

[0031] A rotating rod 703 is fixedly connected to the lower surface of the rotating plate 5. The rotating rod 703 passes through the lower fixed plate 4 and is fixedly connected to multiple stirring rods 704 at the bottom. When the rotating plate 5 rotates, it can drive the multiple stirring rods 704 to rotate, flatten the material on the upper part of the filter plate 701, and perform auxiliary screening to increase the screening effect.

[0032] The upward pulling mechanism 9 includes a fixed cylinder 901, and a movable rod 902 is slidably connected to the inner wall of the fixed cylinder 901. The lower end of the movable rod 902 is fixedly connected to the dustproof plate 10. The movable rod 902 can slide inside the fixed cylinder 901, so that the dustproof plate 10 can move up and down. The middle part of the dustproof plate 10 is inclined from high to low towards the edge. The diameter of the middle part of the feed cylinder 8 is larger than the diameter of the dustproof plate 10. The dustproof plate 10 is stuck at the upper end of the feed cylinder 8 with a smaller diameter. When the dustproof plate 10 moves downward, the material slides towards the edge of the dustproof plate 10 under the action of gravity, so that the material can move downward into the interior of the feed cylinder 8.

[0033] A tension spring 903 is installed inside the fixed cylinder 901. The upper end of the tension spring 903 is fixedly connected to the inner top wall of the fixed cylinder 901, and the lower end of the tension spring 903 is fixedly connected to the movable rod 902. The tension spring 903 provides an upward pulling force to the movable rod 902. In the absence of external force, the dustproof plate 10 is stuck at the position with the smaller diameter of the feed cylinder 8 to prevent dust. When the material falls onto the dustproof plate 10, the gravity is greater than the pulling force of the tension spring 903, causing the dustproof plate 10 to move downward.

[0034] A support rod 904 is fixedly connected to the outer surface of the fixed cylinder 901. The end of the support rod 904 away from the fixed cylinder 901 is fixedly connected to the feed cylinder 8. The support rod 904 fixes the fixed cylinder 901.

[0035] Working principle: When in use, the material is poured into the upper part of the dustproof plate 10. Under the action of gravity, the dustproof plate 10 moves downward. The material slides to the edge of the dustproof plate 10 under the action of gravity, allowing the material to move downward into the inside of the feed cylinder 8. After the material enters, the dustproof plate 10 is reset by the action of the upward pulling mechanism 9, thereby sealing the feed cylinder 8 and achieving the dustproof effect. The material is first stored inside the feed cylinder 8. When it is necessary to feed, the power mechanism 6 drives the rotating plate 5 to rotate. The material entering the cavity inside the rotating plate 5 follows the rotation. When the material moves to the position of the round hole on the lower fixed plate 4, it is fed downward. The rotation of the rotating plate 5 isolates the lower material from the upper material, thus forming a second dustproof layer and preventing dust from flying upward to the outside when screening below, achieving the effect of preventing dust from flowing to the outside.
