Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a concrete mixing construction device for water conservancy engineering construction. Background Art

[0002] Water conservancy projects refer to infrastructure construction projects carried out for the purpose of rationally developing, utilizing, saving, protecting water resources, and preventing and controlling water disasters; they mainly include projects such as reservoirs, dams, levees, water diversion channels, irrigation systems, and hydropower stations. Such projects need to be constructed in a complex natural environment, involving earthworks, concrete structure construction, and water flow control technologies. As the main building material for water conservancy projects, concrete is widely used in load-bearing structures, water retaining structures, and water channels. Water conservancy project construction often has extremely high requirements for concrete quality, which must not only ensure structural strength and durability, but also adapt to long-term water erosion and the impact of the natural environment. Therefore, the concrete mixing construction device for water conservancy project construction needs to have efficient, continuous, and stable mixing functions, and be able to quickly supply high-quality concrete on site to meet the needs of large-scale engineering construction.

[0003] Concrete, abbreviated as concrete, is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; it is mixed with water and may contain admixtures and additives in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete, which is widely used in water conservancy projects. Concrete has the characteristics of abundant raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make its scope of use very wide. It is not only used in various water conservancy projects, but also in shipbuilding, machinery industry, marine development, geothermal projects, etc. Concrete is also an important material.

[0004] During the construction of water conservancy projects, concrete is widely used as the main building material in load-bearing structures, water retaining structures, water channels and other facilities. Its quality directly affects the structural strength and durability of the project. However, the existing concrete mixing device has obvious shortcomings in actual use. The existing concrete mixing device only focuses on the basic mixing and stirring of raw materials such as cement, sand, and stone, and lacks subsequent material quality inspection and screening. Although this process is simple and efficient, it cannot guarantee that the mixed concrete is completely uniform and pure. In addition, there is a certain fluctuation in the quality of concrete raw materials. The particles of sand and gravel are of different sizes, and sometimes they are mixed with impurities such as soil and debris. If the mixing process is not time-efficient or the mixing is not sufficient, it is easy to form unevenly mixed lumps or large particles. Due to the lack of fine screening and filtering functions in the device, these uneven materials cannot be removed after mixing, which directly affects the homogeneity and purity of the concrete.

[0029] When the rotating rod 5 rotates, it will drive the transmission block 6 to rotate, and when the transmission block 6 rotates, it will drive the transmission ring 9 to engage and rotate. When the transmission ring 9 rotates, it will drive the mixing barrel 8 to rotate at the same time, so that the rotation direction of the mixing barrel 8 and the rotation direction of the stirring roller 22 are opposite, thereby improving the mixing effect, reducing the labor intensity of the operator, and improving work efficiency.

A clamping groove 2 43 is provided on the top of the blocking block 19, and the clamping groove 2 43 and the clamping block 2 42 are clamped together.

[0035] When the blocking block 19 and the blocking block 20 are separated, one end of the pressing plate 45 is manually pressed so that the one end of the pressing plate 45 squeezes the spring 2 46. When the one end of the pressing plate 45 squeezes the spring 2 46, the pressing plate 45 drives the clamping block 2 42 to move, so that the clamping block 2 42 is conveniently separated from the clamping groove 2 43. After the clamping block 2 42 is separated from the clamping groove 2 43, it can conveniently drive the blocking block 19 and the blocking block 2 20 to move, so that the mixed concrete can fall into the interior of the screening box 12 for collection, thereby facilitating the work of the operator and reducing the labor intensity of the operator.

[0036] Please see attached Figure 4 , Attachment Figure 6 and attached Fig. 9The outer walls of blocking block 19 and blocking block 20 are fixedly connected with handle 2 41, one side of screening box 12 is fixedly connected with handle 13, the driving assembly includes a support block 3, the support block 3 is fixedly connected to the top of the bottom plate 1, the middle part of the support block 3 is fixedly connected with a motor 4, and the end of the rotating rod 5 close to the pulley 7 is fixedly connected to the output end of the motor 4.

[0038] Please see attached Figure 1 The bottom of the base plate 1 is fixedly connected with a plurality of support columns 2, and the top of the base plate 1 is fixedly connected with an operating table 18, which is used for the operator to control the overall operation of the device. The plurality of support columns 2 can facilitate the base plate 1 to be more firmly supported and fixed.

[0039] Working principle: when mixing concrete, start motor 4, when motor 4 works, it will drive the rotating rod 5 to rotate, when the rotating rod 5 rotates, it will drive the transmission block 6 and pulley 1 7 to rotate at the same time, and when the transmission block 6 rotates, it will drive the transmission ring 9 to mesh and rotate, when the transmission ring 9 rotates, it will drive the mixing barrel 8 to rotate at the same time, when the pulley 1 7 rotates, it will drive the pulley 2 16 to rotate at the same time through the synchronous belt 17, when the pulley 2 16 rotates, it will drive the movable rod 15 to rotate, and when the movable rod 15 rotates, it will drive multiple stirring rollers 22 to move, and when the multiple stirring rollers 22 move, they will drive multiple stirring blades 23 to move at the same time, so that the concrete can be mixed.

[0040] When the mixed concrete is to be released, one end of the pressing plate 45 is manually pressed so that the one end of the pressing plate 45 squeezes the spring 2 46. When the one end of the pressing plate 45 squeezes the spring 2 46, the clamping block 2 42 is driven to move, and the clamping block 2 42 is disengaged from the clamping groove 2 43 when moving. When the clamping block 2 42 is disengaged from the clamping groove 2 43, it can drive the blocking block 2 20 and the blocking block 1 19 to move to the opposite side, thereby releasing the mixed concrete.

[0041] When the mixed concrete is to be filtered and screened, the motor 29 is started. When the motor 29 is working, the disc 30 is driven to rotate. When the disc 30 rotates, the slide bar 31 is driven to perform circular motion. When the slide bar 31 performs circular motion, the slide block 32 is driven to translate up and down. When the slide block 32 translates up and down, two rubber hammers 33 are driven to move. When one of the rubber hammers 33 moves, it hammers the surface of the vibration plate 27 to make the vibration plate 27 vibrate. When the vibration plate 27 vibrates, it drives the filter plate 14 to vibrate at the same time, so that the filter plate 14 can quickly screen and filter the concrete better and faster. When the other rubber hammer 33 moves, it can hammer the surface of the mixing barrel 8 to make the inside of the mixing barrel 8 vibrate. When the inside of the mixing barrel 8 vibrates, the concrete can be further mixed.

[0042] When the filter plate 14 needs to be replaced or cleaned, the pull rod 37 is manually pulled to move it. When the pull rod 37 moves, it will drive the moving rod 38 to move at the same time. When the moving rod 38 moves, it will drive the limit block 39 to move. When the limit block 39 moves, it will squeeze the spring 40. When the limit block 39 drives the spring 40 to move, it will also drive the block 35 to move. When the block 35 moves, it will disengage from the slot 36. When the block 35 disengages from the slot 36, the filter plate 14 can be replaced or cleaned.
