Description

Technical Field

[0001] The utility model relates to the technical field of dry-mix mortar proportioning, in particular to a dry-mix mortar proportioning and weighing integrated device. Background Art

[0002] Dry-mixed mortar is usually called hydraulic cement mixed mortar. It refers to a granular or powdered material made by physically mixing dried and sieved aggregates, inorganic cementitious materials (such as cement) and additives in a certain proportion. It is transported to the construction site in bagged or bulk form and can be used directly after adding water and mixing.

[0003] After searching, the Chinese utility model patent with application number 202121768760.9 discloses a dry-mixed mortar proportioning and weighing integrated device. The rotation of the stirring paddle on the left causes sand to continuously fall into the inside of the proportioning bucket. The overall gravity of the proportioning bucket increases, and the weighing sensor sends the detection value to the single-chip microcomputer. When the detection value of the weighing sensor is equal to the set value, the single-chip microcomputer controls the electric butterfly valve on the left to close and open the electric butterfly valve on the right. Similarly, cement falls from the discharge port at the lower end of the cavity on the right into the inside of the proportioning bucket. When the single-chip microcomputer detects that the weight of the cement reaches the set value through the weighing sensor, it controls the motor and the electric butterfly valve on the right to close, completing the proportioning.

[0004] In the above-mentioned disclosed prior art, the inventor believes that, when in use, the materials in the left and right cavities are added separately. First, the materials in the left cavity are added to the proportioning bucket. When the detection value of the weighing sensor is equal to the set value, the electric butterfly valve on the left is closed and the electric butterfly valve on the right is opened, and the materials are added from the right cavity to the proportioning bucket. Although weighing and proportioning can be completed, the different materials are not mixed at all. Since the amount of materials proportioned together is relatively large, the difficulty of mixing in the later stage will also increase. Therefore, the purpose of this application is to propose a dry-mixed mortar proportioning and weighing integrated device that can pre-mix materials to solve the above problems. Utility Model Content

[0008] A discharge port is provided at the bottom of the premixing bin, and the premixing bin is fixed to the upper end of the mixing bin. A connecting pipe is provided between the premixing bin and the feeding bin. The material in the feeding bin enters the premixing bin through the connecting pipe, and is stirred by the stirring assembly in the premixing bin and then discharged through the discharge port at the bottom of the premixing bin.

[0009] Preferably, a mixing mechanism is provided inside the mixing bin, and the mixing mechanism includes a rotating shaft rotatably installed in the mixing bin, a spiral mixing blade fixed on the side of the rotating shaft, and a driving device connected to the mixing bin for driving the rotating shaft to rotate.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 The specific implementation methods of the present utility model are further described in detail.

[0024] like Figure 1-4 As shown, the utility model is a dry-mix mortar proportioning and weighing integrated device, comprising a mixing bin 1, a feeding bin 2 for adding materials into the mixing bin 1, a pre-mixing bin 3 connected between the feeding bin 2 and the mixing bin 1 for pre-mixing the materials, and a stirring assembly 4 provided in the pre-mixing bin 3 for stirring the materials;

[0025] Among them, the number of feeding bins 2 is several, and the feeding bins 2 are fixed at the upper end of the mixing bin 1 for storing materials such as aggregates and cement. An electric valve is installed at the bottom of the feeding bin 2, and the speed of feeding is conveniently controlled by controlling the opening size of the electric valve;

[0026] A discharge port 31 is provided at the bottom of the premixing bin 3, and the premixing bin 3 is fixed at the upper end of the interior of the mixing bin 1. A connecting pipe 5 is provided between the premixing bin 3 and the feeding bin 2, and a screw feeder 6 is installed inside the connecting pipe 5. When in use, the material is first added to the feeding bin 2, and then the electric valve at the bottom of the feeding bin 2 is opened to allow the materials in different feeding bins 2 to enter the premixing bin 3 together through the screw feeder 6. After being stirred by the stirring component 4 in the premixing bin 3, the materials are discharged through the discharge port 31 at the bottom of the premixing bin 3. In this way, the preliminary mixing of the materials is achieved during the process of adding the materials, thereby reducing the workload of mixing during later use.

[0027] Furthermore, a mixing mechanism 7 is provided inside the mixing bin 1 for further mixing the materials added to the mixing bin 1. The mixing mechanism 7 includes a rotating shaft 71 rotatably installed in the mixing bin 1, a spiral mixing blade 72 fixed to the side of the rotating shaft 71, and a driving device 73 connected to the mixing bin 1 for driving the rotating shaft 71 to rotate. The driving device 73 can drive the rotating shaft 71 to rotate. When the rotating shaft 71 rotates, the spiral mixing blade 72 is driven to rotate. When the spiral mixing blade 72 rotates, the material in the mixing bin 1 is stirred, so that the material mixing is more uniform.

[0028] In some embodiments, the rotating shaft 71 is arranged coaxially with the premixing bin 3, and the upper end of the rotating shaft 71 is rotatably arranged in the premixing bin 3. The stirring assembly 4 includes a stirring blade 41 fixed to the side of the rotating shaft 71, so that when the rotating shaft 71 rotates, the stirring blade 41 is driven to rotate together to stir the material in the premixing bin 1.

[0029] In some embodiments, a grinding and dispersing disk 10 is fixed to a rotating shaft 71 below the discharge port 31 of the premixing bin 3, and a grinding roller 33 is installed on the bottom side of the premixing bin 3 through a mounting frame 32. The grinding roller 33 is fixed in position, and its bottom is in rolling contact with the surface of the grinding and dispersing disk 10. After cement and other materials are premixed in the premixing bin 3, they are quickly discharged to the surface of the grinding and dispersing disk 10 through the discharge port 31. The grinding and dispersing disk 10 is driven to rotate by the rotation of the rotating shaft 71, so that the grinding roller 33 rolls and crushes on the surface of the grinding and dispersing disk 10, so that the agglomerated materials can be better ground and dispersed.

[0030] In order to enable the material falling on the surface of the grinding and dispersing disk 10 to be discharged quickly, the grinding and dispersing disk 10 is preferably an umbrella structure, and a stopper 11 is provided on the circumferential edge of the grinding and dispersing disk 10, and a leakage gap 12 is provided between the stoppers 11. The diameter of the grinding and dispersing disk 10 is larger than the diameter of the premixing bin 3. In order to ensure the efficiency of the ingredients, the grinding and dispersing disk 10 is set to an umbrella structure. In this way, when the fully dispersed material falls on the surface of the grinding and dispersing disk 10, it can quickly roll down through the inclined surface and be discharged through the leakage gap 12. Only a small amount of material that is not completely dispersed remains on the surface of the grinding and dispersing disk 10. When the grinding and dispersing disk 10 rotates, the agglomerated material can be crushed by the grinding roller 33.

[0031] In some embodiments, the driving device 73 is a servo motor fixed to the upper end of the mixing bin 1 , and the output shaft of the servo motor is transmission-connected to the upper end of the rotating shaft 71 .

[0032] In order to facilitate weighing of the materials in the mixing bin 1 , a fixing frame 8 is fixed to the lower end of the mixing bin 1 , and a weighing sensor 9 is installed at the bottom of the fixing frame 8 .

[0033] The working principle of the dry-mix mortar proportioning and weighing integrated device of the utility model is as follows:

[0034] Aggregates, cement, and other materials are added to the premixing bin 3 through multiple feeding bins 2. The materials first enter the premixing bin 3, where they are initially mixed by the stirring assembly 4. The premixed materials are discharged through the discharge port 31 at the bottom of the premixing bin 3 and fall onto the grinding and dispersion disk 10 for further dispersion and grinding. At the same time, the mixing mechanism 7 in the mixing bin 1 further mixes the incoming materials to ensure uniformity. Throughout the entire process, the weighing sensor 9 below the mixing bin 1 monitors the weight of the materials in real time to achieve precise proportioning, realizing efficient and accurate dry-mix mortar production.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
