Description

Technical Field

[0001] This utility model relates to the field of concrete preparation technology, and in particular to a concrete raw material proportioning device. Background Technology

[0002] The mix proportions of concrete are a key parameter determining its performance. It typically consists of cement, water, sand, and aggregate mixed in specific ratios, with admixtures or additives added when necessary. Mix design must comprehensively consider strength, workability, and economy: cement strength grade and water-cement ratio together determine compressive strength; sand ratio and slump control fluidity; adding fly ash, mineral powder, etc., can reduce cement usage and lower costs. In actual construction, adjustments must be made dynamically based on aggregate gradation and moisture content to ensure concrete performance meets standards.

[0003] In existing methods of raw material weighing and proportioning, the materials are mostly weighed manually on a weighing platform. This method is inefficient, prone to errors, and the weighed materials often adhere to the conveying pipes when fed into the mixer, leading to material waste and discrepancies between the weighed and actual materials entering the mixer. To overcome these disadvantages, this invention provides a raw material proportioning device for concrete. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a concrete raw material proportioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete raw material proportioning device, comprising a base plate, an electric lever fixedly connected to the top of the base plate, a batching component disposed at the top of the base plate and on one side of the electric lever, a hopper fixedly connected to the base plate, a conveying pipe fixedly connected to the hopper, a storage component disposed at the top of the base plate and around the batching component, and a second support frame fixedly connected at the top of the base plate and around the hopper, with a conveying component disposed at the bottom of the second support frame.

[0006] Furthermore, the batching assembly includes a weighing instrument that is fixedly connected to the top of the base plate and to one side of the electric lever. A weighing chamber is fixedly connected to the top of the weighing instrument, and a push plate is slidably connected to the weighing chamber. One side of the push plate is fixedly connected to the output end of the electric lever.

[0007] Furthermore, the storage assembly includes a first support frame fixedly connected to the top of the base plate and located around the dispensing assembly. A storage chamber is fixedly connected to the top of the first support frame, and a solenoid valve is fixedly connected to the outlet of the storage chamber through the first support frame.

[0008] Furthermore, the conveying assembly includes a rotating rod rotatably connected to the bottom end of the second support frame, a conveying blade fixedly connected to the rotating rod and located in the conveying pipe, a scraper fixedly connected to the rotating rod and located in the hopper, and a power assembly provided at the top end of the second support frame.

[0009] Furthermore, the power assembly includes a servo motor fixedly connected to the top of the second support frame, and the output end of the servo motor is fixedly connected through the second support frame and one end of the rotating rod.

[0010] Furthermore, support legs are fixedly connected to the four corners of the bottom of the base plate.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention uses solenoid valves on the batching and storage components to precisely batch the materials. After batching, an electric lever and pusher plate push the raw materials from the weighing chamber into the hopper, preventing a small amount of raw materials from sticking to the weighing chamber, which would cause the batched raw material weight to be inconsistent with the actual weight and affect the next batching ratio. Furthermore, scrapers and conveying blades prevent the raw materials from sticking to the hopper and conveying pipe during transport, avoiding the problems of raw material waste and uneven batching.

[0021] As shown in the figure, the batching assembly includes a weighing instrument 4 that is fixedly connected to the top of the base plate 1 and to one side of the electric lever 3. A weighing chamber 5 is fixedly connected to the top of the weighing instrument 4. A push plate 6 is slidably connected to the weighing chamber 5. One side of the push plate 6 is fixedly connected to the output end of the electric lever 3, and is used to weigh the raw materials according to their weight.

[0022] As shown in the figure, the material storage component includes a first support frame 7 fixedly connected to the top of the base plate 1 and located around the batching component. A material storage chamber 8 is fixedly connected to the top of the first support frame 7. A solenoid valve 9 is fixedly connected to the outlet of the material storage chamber 8 through the first support frame 7 for storing raw materials, eliminating the need for operators to frequently add materials to the device.

[0023] As shown in the figure, the conveying assembly includes a rotating rod 12 rotatably connected to the bottom end of the second support frame 15, a conveying blade 13 fixedly connected to the rotating rod 12 and located in the conveying pipe 10, a scraper 14 fixedly connected to the rotating rod 12 and located in the hopper 11, and a power assembly provided at the top of the second support frame 15 for feeding raw materials into the mixer.

[0024] As shown in the figure, the power assembly includes a servo motor 16 fixedly connected to the top of the second support frame 15.

[0025] As shown in the figure, support legs 2 are fixedly connected to the four corners of the bottom of the base plate 1 to support the device and place it above the concrete mixer.

[0026] Working principle: When using the device, first check if the entire device is intact. After the inspection, move the device above the mixer. Then, add the corresponding raw materials to each storage chamber 8. Then, set the weight to be weighed by the weighing instrument 4 below each storage chamber 8. After setting, start the servo motor 16 to drive the rotating rod 12 to rotate, which in turn causes the conveying blade 13 to rotate on the conveying pipe 10 and the scraper 14 to rotate on the hopper 11. Then, the feeding begins. At this time, the solenoid valve 9 opens, and the raw materials in the storage chamber 8 fall onto the weighing chamber 5. The weighing instrument 4 begins to weigh the raw materials on the weighing chamber 5. When the set weight is reached, the solenoid valve 9 closes and the feeding stops. Then, the electric lever 3 pushes the push plate 6 to push the raw materials on the weighing chamber 5 into the hopper 11. The raw materials enter the conveying pipe 10 along the hopper 11 and are then conveyed to the mixer by the conveying blade 13. The raw materials attached to the hopper 11 are scraped off by the scraper 14.
