Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, and in particular to a road and bridge construction batching and mixing machine. Background Technology

[0002] Road and bridge construction refers to a series of civil engineering construction activities carried out for the construction and maintenance of highways, urban roads and bridges, including route surveying, roadbed and bridge pier and abutment construction, pavement paving, expansion joint installation, railing and guardrail construction, drainage system construction, etc. Road and bridge construction batching mixer is a piece of equipment specifically used in road and bridge construction projects, mainly used for mixing concrete, asphalt or other construction materials.

[0003] Traditional road and bridge construction batching mixers are used by adding raw materials into the mixing drum according to the specified ratio, then mixing the raw materials inside the drum by the mixing blades, and finally discharging the mixed raw materials through the discharge port.

[0004] Although traditional road and bridge construction batching and mixing machines can complete the mixing and mixing of raw materials, they lack an adjustable structure for the discharge port angle. This means they are only suitable for buckets of the same height. Since different construction sites use buckets of different heights, if the discharge port angle cannot be adjusted, it will not be able to align with the bucket, thus reducing the equipment's versatility. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a road and bridge construction material mixing machine, which aims to improve the existing technology that lacks an adjustable structure for the angle of the discharge port during material feeding, resulting in it only being suitable for material buckets of the same height. Different construction sites use material buckets of different heights, and if the angle of the discharge port cannot be adjusted, it will be unable to align with the material bucket.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A road and bridge construction material mixing machine, comprising:

[0008] support;

[0009] A mixing tank, which is fixedly connected to the top of the support;

[0010] The discharge port is located inside the mixing tank on the left side.

[0011] A feeding plate, which is rotatably connected to the bottom left side of the mixing tank;

[0012] A fixing plate is fixedly connected to the outer right side of the feeding plate;

[0013] An arc-shaped plate, which is fixedly connected to the outer right side of the feed plate;

[0014] A movable block and a protrusion, wherein the movable block is slidably connected to the inner bottom of the fixed plate, and the protrusion is fixedly connected to the outside of the movable block;

[0015] A spring and a plug, wherein the spring is fixedly connected to the bottom of the movable block and the plug is fixedly connected to the top of the movable block;

[0016] And a water supply component, which is used to automatically add water when mixing construction materials.

[0017] Furthermore, the water addition assembly includes a storage tank, which is fixedly connected to the middle of the support. A liquid level window is installed on the front side inside the storage tank. A water pump is fixedly connected to the rear side inside the support. The input end of the water pump is fixedly connected to the inside of the storage tank. The output end of the water pump is fixedly connected to a delivery pipe. An arc-shaped pipe is provided on the top of the stirring tank. The top of the delivery pipe is fixedly connected to the inside of the arc-shaped pipe. Spray nozzles are installed on both sides of the outside of the arc-shaped pipe.

[0018] Furthermore, a motor is installed at the bottom of the mixing tank, and a rotating rod is fixedly connected to the output end of the motor. The rotating rod is rotatably connected inside the mixing tank, and a mounting plate is fixedly connected to the top of the rotating rod. Connecting rods are fixedly connected to the outer perimeter of the mounting plate. Stirring blades are fixedly connected to the bottom of multiple connecting rods. A rotating ring is fixedly connected to the middle of the rotating rod, and a fixing rod is fixedly connected to the outside of the rotating ring.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, when adjusting the angle of the feeding plate, the downward protrusion drives the moving block and the insert block to move down, compressing the spring. When the insert block disengages from the adjustment hole, the arc plate is moved to adjust the angle of the feeding plate. After adjusting to the appropriate angle, any adjustment hole and the insert block are aligned.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-5 This utility model provides an embodiment of a road and bridge construction batching and mixing machine, comprising: a support 1; a mixing drum 2, which is fixedly connected to the top of the support 1; a discharge port 13, which is opened inside the left side of the mixing drum 2; a discharge plate 14, which is rotatably connected to the bottom left side of the mixing drum 2; a fixing plate 15, which is fixedly connected to the outside right side of the discharge plate 14; an arc-shaped plate 16, which is fixedly connected to the outside right side of the discharge plate 14; a moving block 18 and a protrusion 19, wherein the moving block 18 is slidably connected to the inner bottom of the fixing plate 15, and the protrusion 19 is fixedly connected to the outside of the moving block 18; and a spring. Spring 20 and insert block 21 are fixedly connected to the bottom of movable block 18 and to the top of movable block 18, respectively; and a water-adding component is used to automatically add water when mixing construction materials. Adjustment holes 17 are provided on both sides of the inside of the arc plate 16. Insert block 21 is inserted into any adjustment hole 17. A sliding hole 22 is provided inside the fixed plate 15. The arc plate 16 is slidably connected inside the sliding hole 22. The sliding hole 22 facilitates the movement of the arc plate 16. A through hole 31 is provided on the outside of the fixed plate 15. Protrusion 19 is slidably connected inside the through hole 31. The through hole 31 facilitates the movement of the protrusion 19.

[0037] Specifically, when adjusting the tilt angle of the mixer's feed plate 14, the operator first needs to press down the protrusion 19. The protrusion 19 causes the movable block 18, which is fixedly connected to it, to slide downwards. At the same time, the insert 21 fixedly installed on the top of the movable block 18 also moves downwards synchronously. During this process, the spring 20 fixedly connected to the bottom of the movable block 18 is gradually compressed. After being subjected to external force, the spring 20 undergoes elastic deformation and stores elastic potential energy. As the insert 21 continues to move downwards, when the insert 21 completely disengages from the adjustment hole 17 pre-opened on the arc plate 16, the arc plate 16 is in a freely movable state. At this time, the operator can push the arc plate 16 to move in an arc along the sliding hole 22 opened inside the fixed plate 15 according to actual needs. Since the top of the arc plate 16 is fixedly connected to the feeding plate 14, the movement of the arc plate 16 will directly cause the feeding plate 14 to change angle, thereby adjusting the tilt angle of the feeding plate 14. After the feeding plate 14 is tilted to a suitable angle, the operator aligns one of the adjustment holes 17 on the outer sides of the arc plate 16 with the insert block 21, and then releases the protrusion 19. Under the rebound force of the spring 20, the insert block 21 will automatically reset and insert into the aligned adjustment hole 17, thus fixing the angle of the feeding plate 14. By adjusting the tilt angle of the feeding plate 14, the mixture after stirring can be accurately fed into both high and low material buckets, avoiding the problem of material deviation or difficulty in receiving materials during the feeding process, thereby improving the versatility of the equipment.

[0038] Reference Figures 2-6 The water supply assembly includes a storage tank 23, which is fixedly connected to the middle of the support 1. A level window 24 is installed on the front side of the inside of the storage tank 23 to facilitate viewing the remaining water level. A water pump 26 is fixedly connected to the rear side of the inside of the support 1. The input end of the water pump 26 is fixedly connected to the inside of the storage tank 23, and the output end of the water pump 26 is fixedly connected to a delivery pipe 27. An arc-shaped pipe 28 is provided on the top of the stirring tank 2. The top of the delivery pipe 27 is fixedly connected to the inside of the arc-shaped pipe 28, and both sides of the outside of the arc-shaped pipe 28 are... A nozzle 29 is installed to facilitate the addition of water to the interior of the mixing tank 2. A filling pipe 25 is fixedly connected to the outside of the storage tank 23, and a sealing cap is installed on the outside of the filling pipe 25. The filling pipe 25 facilitates the addition of water to the interior of the storage tank 23, and the sealing cap facilitates the sealing operation of the filling pipe 25. An installation rod 30 is fixedly connected to both sides of the outside of the arc-shaped pipe 28. The bottom of the two installation rods 30 is fixedly connected to the top sides of the mixing tank 2, and the installation rods 30 facilitate the fixation of the arc-shaped pipe 28.

[0039] Specifically, when mixing the raw materials required for road and bridge construction, the water pump 26 is first started. Water is drawn from the storage tank 23 by the water pump 26 and transported through the delivery pipe 27 connected to the water pump 26 to the arc-shaped pipe 28 at the top of the mixing tank 2. Spray nozzles 29 are installed on both sides of the arc-shaped pipe 28, which evenly spray the delivered water into the mixing tank 2. In this way, automatic water addition is achieved when mixing raw materials (such as cement, sand, etc.), ensuring the appropriate moisture content and proportion of the mixture, and improving the mixing quality. In addition to ensuring the uniformity of the finished product, to facilitate operators in monitoring the water level inside the storage tank 23 at any time, a liquid level window 24 is installed on the front of the storage tank 23. The liquid level window 24 is made of transparent acrylic material. Through its observation window, operators can directly view the current water level without opening the storage tank 23, thereby enabling timely water replenishment and avoiding mixing interruptions due to insufficient water supply. This achieves automatic water spraying into the mixing tank 2 when mixing the raw materials required for road and bridge construction, eliminating the need for manual water addition by operators and thus improving overall construction efficiency.

[0040] Reference Figures 1-4 A motor 4 is installed at the bottom of the mixing tank 2. A rotating rod 5 is fixedly connected to the output end of the motor 4. The rotating rod 5 is rotatably connected inside the mixing tank 2. A mounting plate 6 is fixedly connected to the top of the rotating rod 5. Connecting rods 7 are fixedly connected to the outer perimeter of the mounting plate 6. Stirring blades 8 are fixedly connected to the bottom of the multiple connecting rods 7. The stirring blades 8 facilitate the mixing of raw materials inside the mixing tank 2. A rotating ring 9 is fixedly connected to the middle of the rotating rod 5. A fixing rod 10 is fixedly connected to the outside of the rotating ring 9. A scraper 11 is fixedly connected to the outside of the fixing rod 10. The scraper 11 facilitates the scraping of raw materials adhering to the inner wall of the mixing tank 2. The scraper 11 fits against the inner wall of the mixing tank 2. A mounting ring 3 is fixedly connected to the bottom of the mixing tank 2. The motor 4 is fixedly connected inside the mounting ring 3. The mounting ring 3 facilitates the fixing of the motor 4. Hanging holes 12 are opened on both sides of the outside of the mixing tank 2. The hanging holes 12 facilitate the movement of the mixer.

[0041] Specifically, when using this mixer, the raw materials required for road and bridge construction are first placed into the mixing drum 2 according to the specified proportions. Then, the motor 4 is started. The motor 4 drives the rotating rod 5 fixed at the output end to rotate. The rotating rod 5 drives the mounting plate 6 fixed at the top to rotate. The mounting plate 6 drives the connecting rods 7 fixed around the outside to rotate. The multiple connecting rods 7 drive the mixing blades 8 fixed at the bottom to rotate inside the mixing drum 2. The rotation of the mixing blades 8 facilitates the mixing of the raw materials placed inside the mixing drum 2. At the same time, when the rotating rod 5 rotates, it drives the rotating ring 9 fixed in the middle to rotate. The rotating ring 9 drives the fixed rod 10 fixed on the outside to rotate. The fixed rod 10 drives the scraper 11 fixed on the outside to rotate. The rotation of the scraper 11 can scrape off the raw materials adhering to the inner wall of the mixing drum 2, making them evenly mixed. This facilitates the mixing of raw materials required for road and bridge construction, shortens the material preparation time, and improves the overall construction progress.

[0042] Working principle: When the tilt angle of the feed plate 14 needs to be adjusted, the downward-moving protrusion 19 first moves the externally fixed moving block 18 downward inside the fixed plate 15. As the moving block 18 moves, it also moves the top-fixed connecting insert 21 synchronously. Simultaneously, the moving block 18 compresses the bottom-fixed connecting spring 20, causing the spring 20 to deform under force. Then, after the insert 21 disengages from the adjustment hole 17 inside the arc-shaped plate 16, the moving arc-shaped plate 16 moves inside the sliding hole 22 inside the fixed plate 15. As the arc-shaped plate 16 moves, it compresses the top-fixed connecting spring 20. The top-fixed feeding plate 14 is tilted at an angle. When the feeding plate 14 is tilted to a suitable angle, the arbitrary adjustment holes 17 on both sides of the outer side of the arc plate 16 are aligned with the insert block 21. After alignment, the protrusion 19 is released. Under the reaction force of the spring 20, the insert block 21 is reset and inserted into the aligned adjustment hole 17 to complete the adjustment of the tilt angle of the feeding plate 14. This makes it easy to adjust the tilt angle of the feeding plate 14 of the mixer, so that the mixed material can be accurately aligned with the material buckets of different heights, avoiding material deviation or difficulty in receiving material, thereby improving the versatility of the equipment.

[0043] When raw materials are needed for road and bridge construction, water pump 26 is started to draw water from the inside of storage tank 23. The water is then transported to the inside of arc-shaped pipe 28 through delivery pipe 27. Finally, the water is sprayed into the inside of mixing tank 2 through nozzles 29 installed on both sides of the outside of arc-shaped pipe 28. By installing a liquid level window 24 on the front of the outside of storage tank 23, the remaining water level inside storage tank 23 can be checked in time. This makes it easy to automatically add water to the inside of mixing tank 2 when raw materials are needed for road and bridge construction, eliminating the need for manual water addition by operators, shortening construction preparation time, and thus improving overall construction efficiency.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
