Description

Technical Field

[0001] This utility model relates to the technical field of crushed stone proportioning devices, specifically to a crushed stone proportioning device for improving the stability of traditional cement. Background Technology

[0002] In cement concrete, crushed stone (coarse aggregate) and sand (fine aggregate) together form the concrete skeleton. These aggregates not only increase the volume stability of the concrete but also enhance the overall structural strength through bonding with the cement paste. Good gradation reduces porosity and increases density, thereby enhancing the durability and compressive strength of the concrete. Conversely, inappropriate gradation can lead to segregation or bleeding in the concrete, affecting its uniformity and stability.

[0003] Existing technology discloses a cement-stabilized crushed stone mixture proportioning device (authorization announcement number: CN219902734U). This device uses a weighing structure to weigh the raw materials when batching is required, and then directly pours the weighed materials into a mixing tank for mixing. This design avoids the inconvenience of manual feeding and is relatively convenient to use. However, this device still has some problems: First, during the material pouring process, because the materials contain a lot of fine dust, falling into the mixing tank from above may cause dust to splash, and long-term exposure to this environment may have adverse effects on the health of workers; second, the device needs to weigh multiple materials one by one during operation, making it difficult to process multiple materials simultaneously, thus reducing overall work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a crushed stone proportioning device that improves the stability of traditional cement, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A crushed stone proportioning device for improving the stability of traditional cement includes: a housing, on one side of which a display and an operation panel are fixedly installed;

[0007] The feature is that two storage boxes are arranged side by side inside the box, and two weighing boxes are arranged side by side below the storage boxes. Each storage box is fixedly equipped with a discharge valve for discharging material into the weighing box.

[0008] The weighing box consists of two weighing boxes separated by a baffle. Each weighing box has a frame that is slidably installed inside it. Each frame has a weighing device that is fixedly installed inside it. The adjacent sides of the two frames are hinged together by ear plates. The baffle has a clearance groove for the ear plates to pass through. A cylinder for driving the hinge point of the ear plates to rise and fall is fixedly installed in the clearance groove.

[0009] A mixing chamber for mixing materials is fixedly installed below the weighing box, and the mixing chamber is provided with a discharge port.

[0010] As a further improvement, the unloading valve includes a housing, which is fixedly connected to the outlet of the storage tank. A rotating shaft is rotatably installed inside the housing, and guide blades are evenly distributed around the circumference of the rotating shaft.

[0011] As a further improvement, movable shafts are fixedly installed on the two sides of the frame adjacent to the ear plate, and the movable shafts are symmetrically installed at the end away from the ear plate; sliding shafts are also fixedly installed on the two sides, and the sliding shafts are installed at the end close to the ear plate.

[0012] As a further improvement, the inner wall of the weighing box is provided with a moving groove for horizontal movement of the moving shaft and a sliding groove for vertical sliding of the sliding shaft; the inner wall of the weighing box opposite to the baffle is also provided with a positioning groove for the frame to be inserted.

[0013] As a further improvement, the hinge point of the ear plate is connected to a connecting block that does not affect its movement, and the connecting block is fixedly installed with the piston rod of the cylinder.

[0014] As a further improvement, several support feet are fixedly installed at the bottom of the housing.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] This solution, by setting up two sets of parallel storage bins and weighing bins, can handle two different materials simultaneously.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Basic principle: This scheme sets up two independent storage boxes 2 and weighing boxes 4 in parallel. The material enters the weighing box 4 through the discharge valve 3 for weighing. The guide vanes 33 in the discharge valve 3 ensure that the material flows out evenly and effectively reduces dust splashing. After the material is weighed, the cylinder 432 lifts the hinge point of the frame 41. At this time, the sliding shaft 413 moves upward along the sliding groove 415, and the moving shaft 412 moves towards the baffle 43 along the moving groove 414. The frame 41 tilts, and the channel between the weighing box 4 and the mixing box 5 is opened. The material enters the mixing box 5 for mixing under the action of gravity.

[0028] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0029] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0030] Example 1 of the crushed stone proportioning device for improving the stability of traditional cement provided by this utility model:

[0031] like Figure 1-2 As shown, a crushed stone proportioning device for improving the stability of traditional cement includes a box 1. Inside the box 1, a storage box 2, a weighing box 4, and a mixing box 5 are fixedly installed. A display 11 and an operation panel 12 are fixedly installed on one side of the box 1. The display 11 is used to display parameter information, and the operation panel 12 is used to set parameters, including but not limited to the quality of each material and error codes. Several support feet 13 are fixedly installed at the bottom of the box 1 to increase the overall stability.

[0032] The aforementioned display 11 and operation panel 12 and related systems are existing technologies and will not be described in detail here.

[0033] like Figure 2 As shown, two storage bins 2 are arranged side by side inside the housing 1. A weighing bin 4 is located below each storage bin 2. A discharge valve 3 is fixedly installed at the bottom of each storage bin 2, used to transfer material from the storage bin 2 to the weighing bin 4. The discharge valve 3 includes a housing 31, the inlet of which is fixedly connected to the outlet of the storage bin 2, and the outlet of which is located at its bottom. A rotating shaft 32 is rotatably installed inside the housing 31, driven by a motor (not shown in the figure). Guide blades 33 are fixedly installed on the rotating shaft 32, evenly distributed around its circumference, with their ends maintaining close contact with the inner wall of the circular housing 31. This ensures that material can be evenly and accurately fed from the storage bin 2 into the weighing bin 4, avoiding dust splashing and the problem of excessive material release requiring manual removal.

[0034] The top of the box 1 is hinged with a top cover (not shown in the figure) for sealing the storage box 2 to prevent rain, snow or strong winds from affecting the materials during outdoor operations.

[0035] like Figure 2-4As shown, two weighing boxes 4 are separated by a baffle 43. A frame 41 is slidably installed inside each weighing box 4, and a weighing device 42 is fixedly installed inside the frame 41 for accurately measuring the weight of each material. The adjacent sides of the two frames 41 are hinged by ear plates 411. The baffle 43 has a clearance groove 431 for the ear plates 411 to pass through. A cylinder 432 is fixedly installed on the bottom surface of the clearance groove 431 for driving the hinge point of the ear plates 411 to rise and fall along the clearance groove 431.

[0036] A movable shaft 412 and a sliding shaft 413 are fixedly installed on the two sides adjacent to the ear plate 411 of the frame 41, respectively. The movable shaft 412 is symmetrically installed at the end away from the ear plate 411 for horizontal movement; the sliding shaft 413 is installed at the end closer to the ear plate 411 for vertical sliding. The inner wall of the weighing box 4 is provided with a movable groove 414 for horizontal movement of the movable shaft 412 and a sliding groove 415 for vertical sliding of the sliding shaft 413 to ensure smooth movement of the frame 41. The inner wall of the weighing box 4 opposite to the baffle 43 is also provided with a positioning groove 416 for insertion of the frame 41 to ensure the accurate position and stability of the frame 41 when it is in a horizontal state.

[0037] In addition, the weighing box 4 is located between the storage box 2 and the mixing box 5. Its space is relatively sealed, which effectively solves the environmental problems and health risks caused by dust during material transfer.

[0038] like Figure 5 As shown, the hinge point of the ear plate 411 is connected to the cylinder 432 via a connecting block 433. The connecting block 433 is a semi-frame shape with its opening facing upwards. The frames on both sides of the connecting block 433 are fixedly installed with pins 434. The bottom of the connecting block 433 is fixedly installed with the piston rod of the cylinder 432, allowing the cylinder 432 to drive the lifting and lowering of the hinge point of the ear plate 411. In addition, the upper half of the bottom frame of the connecting block 433 is semi-circular, providing sufficient space for the rotation of the ear plate 411. This design method, driven by the cylinder 432, controls the tilt angle of the frame 41, enabling rapid transfer of materials from the weighing box 4 to the mixing box 5.

[0039] The aforementioned motor (used to drive the unloading valve 3), weigher 42, cylinder 432, display 11 and control panel 12 are electrically connected. The required material mass can be preset through the control panel 12. When the preset value is reached, the unloading valve 3 stops, the cylinder 432 starts, and the material enters the mixing box 5 under the action of gravity. This process is automatic and reduces the involvement of personnel.

[0040] like Figure 2 As shown, a mixing tank 5 is fixedly installed below the weighing tank 4 for mixing the materials transferred from the weighing tank 4. In this embodiment, the discharge port 51 is located at the bottom of the mixing tank 5 to facilitate the discharge of the mixed materials. The mixing tank 5 is prior art and will not be described in detail here.

[0041] Embodiment 2 of the crushed stone proportioning device for improving the stability of traditional cement provided by this utility model:

[0042] Its main difference from Example 1 is that, as Figure 4 As shown, the bottom surfaces of both the moving groove 414 and the positioning groove 416 are provided with several downward inclined grooves 417. The inclined grooves 417 are evenly distributed, and the width of the inclined grooves 417 is at most half the diameter of the moving shaft 412, ensuring that the moving shaft 412 can run smoothly in the moving groove 414.

[0043] Weighing box 4 is used for material metering. When the material is poured, some dust or small gravel particles may fall into the moving trough 414 and the positioning trough 416, which may affect the operation of the frame 41. The opening of the inclined trough 417 is conducive to the discharge of obstacles and can ensure the stability of the operation of the scheme.

[0044] The above-described preferred embodiments of the present invention are provided for guidance, but it will be apparent to those skilled in the art that such embodiments are provided merely by way of example. Many modifications, alterations, and alternatives will arise in the mind and spirit of the present invention without departing from its intent. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
