Description

Technical Field

[0001] The invention relates to the technical field of concrete proportioning, and more specifically to a concrete proportioning feeding device for highway bridge construction. Background Art

[0002] Concrete, also known as concrete, is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementing materials, aggregates and water in a certain proportion, stirred and vibrated into shape, and cured under certain conditions. 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 high compressive strength, good durability and wide range of strength grades, which makes its use range very wide. It is not only used in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. The prior art CN213860026U is a concrete proportioning feeding device for highway bridge construction. The device can quantitatively weigh cement and other materials, and after weighing, the cement and other materials are transported downward to the mixing device. This device can make the proportion of cement and other materials more accurate, thereby improving the quality of concrete. However, the device still has the disadvantages that, since the end of the conveying pipe in the device is directly exposed to the outside between the feeding hopper, a large amount of dust will be generated when cement and sand are conveyed and dropped out, causing air pollution and harm to the health of the workers; at the same time, since the device is not convenient for mixing dry materials such as cement and stone, the problem of uneven mixing will occur when adding water and mixing; at the same time, the device is not convenient for quantitative feeding of materials with good proportions, resulting in poor practicality of the device;

[0043] In this embodiment, the L-shaped rod 602 makes the annular rack 601 in an eccentric state, thereby driving the function of the dry material mixing assembly 7.

[0044] Furthermore, the dry material mixing assembly 7 includes a fixed gear 701, a fixed rod 702 is connected and fixed to the bottom of the fixed gear 701, the lower end of the fixed rod 702 is connected and fixed to the lower inner wall of the proportioning barrel 4, the upper outer wall of the fixed rod 702 is rotatably connected to a rotating frame 703, both ends of the upper side of the rotating frame 703 are rotatably connected to mixing rods 704, the upper end of the mixing rod 704 is connected and fixed to an orbiting gear 705, and the orbiting gear 705 is meshed with the fixed gear 701 for transmission.

[0045] In this embodiment, the surrounding gear 705 drives the mixing rod 704 to rotate while rotating in a circle.

[0046] It is worth noting that the rear end of the support seat 8 is connected and fixed to the fixed cover 1 through a connecting plate, and the bottom of the support seat 8 is an annular structure connected and fixed with multiple support rods.

[0047] It is worth noting that the inner walls at both ends of the fixing frame 9 are provided with sliding grooves 901 , the bottom of the rear wall of the fixing frame 9 is connected and fixed with an L-shaped seat 902 , and the right end of the fixing frame 9 is connected and fixed to the bottom of the support seat 8 .

[0048] In this embodiment, the slide groove 901 serves to limit the quantitative feeding component 10 .

[0049] In addition, the quantitative unloading component 10 includes a movable seat 1001, and the outer walls at both ends of the movable seat 1001 are slidably matched with the inner wall of the slide groove 901, and the inner wall of the right end of the movable seat 1001 is connected and fixed with an electric push rod 1002, and the other end of the electric push rod 1002 is connected and fixed with the inner wall of the right end of the support seat 8, and the left end of the movable seat 1001 is connected and fixed with a quantitative barrel 1003, and the lower end of the quantitative barrel 1003 is hingedly connected to a unloading plate 1004, and the bottom surface of the unloading plate 1004 is in friction contact with the top surface of the L-shaped seat 902, and the bottom surface of the quantitative barrel 1003 is connected and fixed with a cloth bag tube 1005.

[0050] In this embodiment, the quantitative barrel 1003 plays the role of quantitative discharging.

[0051] When the highway bridge construction needs to mix concrete, firstly, cement and sand can be poured into one of the feed pipes 201, and gravel and the like can be poured into the other feed pipe 201, wherein the gravel is poured into the transport pipe with a larger diameter. Then, the control value of the delay trigger is set according to the requirements or experience so that the drive motors 202 of the two feed pipes 201 are transmitted at different periodic intervals. The different pipe diameters are conducive to the transmission of different materials, and a highly differentiated ratio difference can be achieved without setting a larger control value of the delay trigger output. Then, the motor 202 is used to drive the auger 203 to rotate, so that the auger 203 transports the cement and the like into the fixed cover 1, and then falls into the proportioning barrel 4. When the auger 203 on the right side rotates, it will drive the bevel gear A204 to rotate, so that the bevel gear A204 drives the bevel gear B301 to rotate, thereby driving the transmission rod 3 to rotate, so that the transmission rod 3 drives the rectangular The rod 302 rotates, so that the rectangular rod 302 will drive the connecting sleeve 503 to rotate, and the connecting sleeve 503 will drive the connected conical plate 501 to rotate, so as to break up the materials falling into the proportioning barrel 4, and then the connecting sleeve 503 will drive the connected L-shaped rod 602 to rotate, thereby driving the annular rack 601 to make an eccentric rotation, and at this time the annular rack 601 will drive the surrounding gear 705 to rotate, so that the surrounding gear 705 rotates in a circle around the outer wall of the fixed gear 701, so that the mixing rod 704 can perform circular rotation stirring to mix various materials with dry materials. As the amount of materials increases, the proportioning barrel 4 will drop, and the weight will be measured under the action of the pressure sensor. When a certain weight is reached, the feeding is stopped and the proportioning is completed; therefore, in the present invention, through the delayed trigger and two transmission tubes with different tube body apertures, various transmission ratios can be adjusted and matched, and the synchronous transportation of different types of materials can also be realized.

[0052] Then, when it is necessary to discharge the material for mixing the concrete, the electric push rod 1002 is used to drive the connected moving seat 1001 to move to the right, so that the metering barrel 1003 will be connected to the bottom of the proportioning barrel 4. At this time, the unloading plate 1004 at the bottom of the metering barrel 1003 will be closed under the action of the L-shaped seat 902, so that the mixed material in the proportioning barrel 4 will fall into the metering barrel 1003, and then the electric push rod 1002 is used to move the moving seat 1001 to the left, so that the top surface of the right end of the moving seat 1001 seals the bottom of the proportioning barrel 4, and then as the unloading plate 1004 is not restricted by the L-shaped seat 902, the unloading plate 1004 is opened, so that the mixed material in the metering barrel 1003 will fall through the bag tube 1005, completing the quantitative discharging.
