Description

Technical Field

[0001] This utility model relates to the field of concrete raw material weighing and batching technology, specifically a concrete raw material weighing and batching device. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering. During the concrete processing, a weighing and batching device is needed to weigh and batch the concrete.

[0003] The announcement number "CN219311648U" discloses an automatic weighing and batching hopper for concrete processing. Through an automatic feeding device and a control cylinder, the material in the batching hopper can be automatically discharged without leaving any material in the hopper, reducing unnecessary waste and saving costs. The automatic weighing device can accurately calculate the weight of each discharge, which is then fed into the mixer for reasonable proportioning with the raw materials, thereby ensuring the quality of the concrete product.

[0004] However, the above technical solutions and existing technologies have the following drawbacks:

[0005] Although this weighing and batching hopper can accurately calculate the weight of each batch, it only has one set of hoppers, which means that in actual use, it can only weigh and batch one type of concrete at a time, and cannot weigh and batch multiple types of concrete at the same time. This results in low work efficiency. Furthermore, this weighing and batching hopper does not have the function of mixing the weighed concrete. A separate mixer needs to be installed around it to mix the weighed concrete raw materials, which not only increases the operating costs for the user, but also occupies a lot of space. Its practicality needs to be further improved. Utility Model Content

The support leg 5 can support and fix the batching box 1.

[0028] The sealing cover plate 2 is equipped with a weighing component 3 at its upper end, which is used to weigh the concrete raw materials so as to accurately mix different types of concrete raw materials in the future. The batching box 1 is equipped with a mixing component 4, which is used to pre-mix the weighed concrete raw materials in the batching box 1. The front face of the batching box 1 is equipped with a control panel, which is connected to the electric discharge valve 36 and the low-speed motor 41 through wires. The control panel allows the staff to control the operation of the electric discharge valve 36 and the low-speed motor 41.

[0029] The weighing assembly 3 includes a weighing hopper 31, a weighing display instrument 32, a support rod 33, a support plate 34, and weighing sensors 35. Multiple weighing sensors 35 are installed on the upper surface of the sealing cover plate 2. The multiple weighing sensors 35 can weigh the concrete raw materials inside the hopper through the support plate 34, the support rod 33, and the weighing hopper 31. The support plate 34 is installed on the upper surface of the weighing sensors 35, and the support plate 34 can support the support rod 33. The support rod 33 is fixedly connected to the upper surface of the support plate 34. The support rod 33 is connected to the weighing hopper 31 and the support plate 34 by welding. The support rod 33 can support the weighing hopper 31. The weighing hopper 31 is fixedly connected to the upper end of the support rod 33. There are three sets of weighing hoppers 31, and the three sets of weighing hoppers 31 are the same in specifications.

These three sets of weighing display instruments 32 can display the weight of the concrete raw materials inside the three weighing hoppers 31 through multiple weighing sensors 35. The detailed internal structure and working principle of the weighing sensors 35 and the weighing display instruments 32 are explained below. All of these are relatively mature technologies in the existing technology, so they will not be described in detail here. An electric discharge valve 36 is installed at the bottom outlet end of the weighing hopper 31. The electric discharge valve 36 makes it convenient for the staff to control the opening and closing of the discharge at the bottom of the weighing hopper 31. A guide pipe 38 is installed at the bottom outlet end of the electric discharge valve 36. The guide pipe 38 can guide the concrete raw materials discharged by the electric discharge valve 36 to the batching box 1. A through cavity 37 is opened on the upper end face of the sealing cover plate 2. The inner diameter of the through cavity 37 is larger than the outer diameter of the guide pipe 38. The through cavity 37 makes it convenient for the guide pipe 38 to be used inside the sealing cover plate 2.

[0031] Example 2:

[0032] Based on Embodiment 1, in this embodiment, by controlling the low-speed motor 41 to drive the transmission rod 49 to reverse, the transmission rod 49 can drive the stirring rod 48 and the stirring support rod 47 to rotate and pre-mix the various concrete raw materials weighed inside the batching box 1. By controlling the low-speed motor 41 to rotate forward, the transmission rod 49 can drive the conveying auger 42 to rotate forward together through the first pulley 44, the transmission belt 45 and the second pulley 46, so that the forward-rotating conveying auger 42 can discharge the concrete raw materials inside the batching box 1 through the discharge cylinder 43.

[0033] The mixing assembly 4 includes a low-speed motor 41, a mixing support rod 47, a mixing rod 48, a transmission rod 49, and a motor support plate 411.

The low-speed motor 41 is installed on the lower end face of the motor support plate 411. When working, the low-speed motor 41 can drive the transmission rod 49 to rotate at a low speed. The transmission rod 49 is installed on the right end of the low-speed motor 41. The transmission rod 49 is connected to the first pulley 44 and the mixing rod 48 by welding. The transmission rod 49 can drive the first pulley 44 and the mixing rod 48 to rotate. The mixing rod 48 is provided on the annular side of the transmission rod 49. The mixing support rod 47 is provided on the annular side of the mixing rod 48. The mixing rod 48 and the mixing support rod 47 are connected by welding. When the mixing rod 48 and the mixing support rod 47 rotate, they can pre-mix the concrete raw materials inside the batching box 1.

[0034] A first pulley 44 is provided on the left side of the annular side of the transmission rod 49. The first pulley 44 can drive the second pulley 46 to rotate via the transmission belt 45. A discharge cylinder 43 is fixedly connected to the bottom of the batching box 1. The discharge cylinder 43 is connected to the batching box 1 by welding.

The discharge cylinder 43 is equipped with a conveying auger 42. The conveying auger 42 is connected to the second pulley 46 and the limiting ring 421 by welding. When the conveying auger 42 rotates forward, it can discharge the concrete raw materials inside the discharge cylinder 43 to the right. Concrete material is discharged to the right, and when reversed, the concrete material inside the discharge cylinder 43 is conveyed to the left to prevent the concrete material inside the discharge cylinder 43 from being discharged. A second pulley 46 is provided at the left end of the conveying auger 42. A transmission belt 45 is connected between the second pulley 46 and the first pulley 44. The second pulley 46 can drive the conveying auger 42 to rotate. A limit ring 431 is installed in the middle of the left end face of the discharge cylinder 43. A limit ring 421 is provided on the left side of the annular side of the conveying auger 42. The limit ring 431 and the limit ring 421 prevent the conveying auger 42 from being displaced during rotation.

[0035] Working Principle: During the use of this device, the operator first puts different types of concrete raw materials to be weighed into three sets of weighing hoppers 31. During this process, multiple weighing sensors 35 can weigh the concrete raw materials inside the hoppers 31 through the support plate 34, support rod 33, and weighing hoppers 31. The three sets of weighing display instruments 32 convert the signals transmitted from the multiple weighing sensors 35 into weight figures, thus displaying the weight of the concrete raw materials inside the three sets of weighing hoppers 31 in real time, allowing the operator to monitor the concrete... After precise proportioning of raw materials, the electric discharge valve 36 is opened to discharge the concrete raw materials inside the weighing hopper 31 into the guide pipe 38, which then guides the discharged concrete raw materials into the batching box 1. Simultaneously, the low-speed motor 41 is reversed, causing the transmission rod 49 to reverse as well. The transmission rod 49 then drives the mixing rod 48 and the mixing support rod 47 to reverse, pre-mixing the various concrete raw materials inside the batching box 1. At the same time, the transmission rod 49 also drives the first pulley 4... 4. When the first pulley 44 rotates together, it drives the second pulley 46 to reverse via the transmission belt 45. This, in turn, causes the second pulley 46 to drive the conveying auger 42 to reverse as well. The reversing conveying auger 42 then transports the concrete material that has fallen into the discharge cylinder 43 to the left. The concrete material being transported to the left accumulates upwards under the obstruction at the left end of the conveying cylinder and is stirred by the mixing rod 48 and the mixing support rod 47, preventing the concrete material from being discharged to the outside during the mixing process. After the concrete material has been stirred for the required time, then... Controlling the low-speed motor 41 to rotate forward will cause the transmission rod 49 to drive the conveying auger 42 to rotate forward together via the first pulley 44, the transmission belt 45, and the second pulley 46. The rotating conveying auger 42 will discharge the concrete material inside the discharge cylinder 43 to the right, while the concrete material inside the batching box 1 will continuously slide into the discharge cylinder 43. This process discharges the mixed concrete material inside the batching box 1 for the next processing step. Once all the concrete material inside the batching box 1 and the discharge cylinder 43 has been discharged, the low-speed motor 41 can be turned off.
