Description

Technical Field

[0001] This invention relates to the field of concrete mixing equipment technology, and in particular to a concrete mixing device and method for use in water conservancy projects. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. It is widely used in civil engineering. Concrete is characterized by abundant and inexpensive raw materials and a simple production process, which has led to its increasing use. Concrete also features high compressive strength, good durability, and a wide range of strength grades.

[0003] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates, water, and, when necessary, admixtures and additives in a certain proportion, uniformly mixing, compacting, and curing. However, existing equipment cannot properly premix various materials when processing concrete, which directly affects the mixing efficiency and processing time of the equipment, greatly increasing the production cost of concrete. In addition, when mixing concrete, the traditional mixing blades have a fixed length, which in turn results in a fixed mixing radius. The mixing area of ​​the equipment is limited, and the mixing effect is poor. Furthermore, during the mixing process, the materials adhere to the inner wall of the equipment, so some materials cannot be effectively mixed, which directly affects the uniformity and quality of the concrete mixture.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a concrete mixing device and method for water conservancy projects, addressing the aforementioned technical deficiencies. This is achieved through the coordinated operation of the adjustment mechanism and the equipment mechanism, which solves the problem of uneven mixing. Furthermore, the coordinated operation of the support rod and the adjustment cylinder allows the concentric rod to move intermittently up and down within the support base plate, continuously changing the mixing radius and position of the first and second mixing blades. Therefore, by altering both the mixing radius and position, the mixing effect of the equipment is improved, leading to more uniform concrete mixing inside the equipment and increased processing efficiency. Finally, the coordinated operation of the premixing mechanism and the cleaning mechanism solves the problems of long processing times and inadequate mixing of the inner wall material in traditional methods.

[0015] A method of using a concrete mixing device for water conservancy projects, comprising the following steps:

[0016] Step 1: When mixing concrete, sand, cement and water are put into the equipment in a certain proportion. Sand and cement are put into the equipment from the feed hopper, and water enters the equipment from the water inlet pipe. Before feeding, the external power supply is controlled to start the drive motor.

[0017] Step 2: The drive motor drives the transmission shaft inside the regulating cylinder to rotate. The transmission shaft drives the concentric rod to rotate through the first transmission plate. The concentric rod drives the matching tube to rotate through the second upper transmission plate. The matching tube drives the spiral shaft to rotate inside the funnel plate. The spiral shaft feeds the material on one hand and premixes the material on the other. In addition, the spiral shaft drives the support shaft on the limit sleeve to rotate. The support shaft drives the gear plate to roll on the ring tooth plate. The support shaft rotates and rotates on its own axis at the same time. The support shaft drives the premixing plate to stir and mix the materials, which helps to improve the equipment's processing efficiency for concrete.

[0018] Step 3: When the spiral shaft rotates, it drives the external transmission gear plate to rotate. Through the transmission between gears, the transmission gear plate drives the transmission wheel to rotate. The transmission wheel drives the reciprocating screw to rotate inside the cross, causing the guide slide plate outside the reciprocating screw to move up and down. During the movement, the guide slide plate drives the moving push plate to clean and push the inner wall of the equipment, pushing the material on the inner wall towards the center and improving the mixing uniformity.

[0019] Step 4: As the concentric rod rotates, it drives the support rod on the positioning sleeve to rotate synchronously. The support rod drives the ball to roll on the adjusting cylinder. Through the cooperation between the support rod and the adjusting cylinder, the concentric rod moves up and down intermittently inside the support base plate, thereby continuously changing the mixing position of the upper and lower mixing components and improving the mixing efficiency.

[0020] During the up-and-down movement of the concentric rod, when moving upward, it is restricted by the positioning plate, and the crank connecting rod pushes the telescopic plate to slide outward of the first mixing blade, thus changing the mixing radius at the upper end of the equipment. When moving downward, it is restricted by the fixed sleeve, and the positioning support rod pushes the moving plate to slide outward of the second mixing blade, thus changing the mixing radius at the lower end of the equipment. Since the telescopic plates and moving plates at the upper and lower ends move in opposite directions, the mixing radius is continuously changed to improve the mixing efficiency of the equipment.

[0021] Step 5: Feeding. During the feeding process, add the corresponding amount of water so that the water enters the equipment directly from the inlet pipe, and the processed concrete is discharged from the outlet pipe for use.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) By cooperating with the adjustment mechanism and the equipment mechanism, the problem of uneven mixing in the equipment is solved. By cooperating with the support rod and the adjustment cylinder, the concentric rod moves up and down intermittently inside the support base plate, thereby continuously changing the mixing radius and mixing position of mixing blade one and mixing blade two. Therefore, the mixing effect of the equipment is improved by changing the mixing radius and mixing position, which helps the concrete inside the equipment to be mixed more evenly and improves the processing efficiency of the equipment.

[0024] (2) By cooperating with the premixing mechanism and the cleaning mechanism, the problems of long processing time and inability to mix the inner wall material are solved. Through the transmission between gears, the support shaft rotates and rotates on its own. The support shaft drives the external premixing plate to stir and mix the various materials entering the funnel plate, thereby reducing the processing time of the equipment. Meanwhile, the guide slide plate outside the reciprocating screw moves up and down, so that the guide slide plate drives the moving push plate to clean and push the material attached to the inner wall of the equipment. Therefore, it can achieve the effect of premixing various materials and cleaning and pushing the material attached to the inner wall of the equipment, which helps to improve the mixing uniformity of the equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see Figure 1-9 This invention relates to a concrete mixing device for water conservancy projects, comprising a supporting base plate 1, a mixing tank 2 fixedly connected to the upper surface of the supporting base plate 1, an upper cover plate 3 fixedly connected to the end of the mixing tank 2 away from the supporting base plate 1, a feeding hopper 4 symmetrically fixedly connected to the upper surface of the upper cover plate 3, a discharge pipe 5 inserted into one side of the mixing tank 2, a water inlet pipe 6 inserted into one side of the upper cover plate 3, a water tank 7 fixedly connected to the end of the water inlet pipe 6 away from the upper cover plate 3, a partition plate 8 fixedly connected inside the mixing tank 2, and a drive motor 9 fixedly connected inside the supporting base plate 1. When mixing concrete, sand, cement, and water are added into the equipment in a certain proportion. The sand and cement are added into the equipment from the feeding hopper 4, and water is added during the feeding process so that the water directly enters the equipment from the water inlet pipe 6. The final processed concrete is discharged from the discharge pipe 5 for use.

[0039] An adjusting cylinder 10 is fixedly connected to the upper surface of the drive motor 9. A drive shaft 11 is inserted inside the adjusting cylinder 10, and the lower end of the drive shaft 11 is connected to the drive motor 9. An adjusting mechanism 12 is fixedly connected to the upper surface of the drive shaft 11. A cross 23 is fixedly connected inside the mixing tank 2. A premixing mechanism 24 is inserted inside the cross 23. A cleaning mechanism 32 is rotatably connected inside the cross 23. Before feeding materials, the external power supply is controlled to start the drive motor 9, which drives the drive shaft 11 inside the adjusting cylinder 10 to... The rotation of the drive shaft 11 causes the adjustment mechanism 12 to operate. The adjustment mechanism 12 includes a drive plate 13, with a concentric rod 14 sleeved on the upper end of the drive plate 13. The concentric rod 14 has a groove inside that matches the drive plate 13. A positioning sleeve 15 is sleeved on the outside of the concentric rod 14. A return spring 16 is sleeved on the outside of the drive plate 13. The upper end of the return spring 16 is fixedly connected to the positioning sleeve 15, and the lower end of the return spring 16 is fixedly connected to the drive shaft 11. The lower surface of the positioning sleeve 15 is symmetrical. A support rod 17 is fixedly connected, and a ball bearing 18 is rotatably connected to the lower end of the support rod 17. A transmission plate 19 is fixedly connected to one end of the concentric rod 14 located inside the mixing tank 2. A matching tube 20 is sleeved on the outside of the transmission plate 19, and the matching tube 20 is rotatably connected to the cross 23. An upper stirring component 21 is sleeved on the outside of the concentric rod 14 near the transmission plate 19, and a lower stirring component 22 is sleeved on the outside of the concentric rod 14 near the partition plate 8. That is, the transmission shaft 11 drives the transmission plate 13 to rotate, so that the transmission plate 13 drives the upper concentric component 22. The rod 14 rotates synchronously, and the rotation of the concentric rod 14 causes the positioning sleeve 15 to rotate. The positioning sleeve 15 causes the support rod 17 to rotate synchronously. The support rod 17 causes the ball bearing 18 to roll on the adjusting cylinder 10. During the rolling of the support rod 17 on the adjusting cylinder 10, the concentric rod 14 moves up and down intermittently inside the support base plate 1. At the same time, the return spring 16 undergoes elastic deformation back and forth, thereby continuously changing the stirring position of the upper stirring component 21 and the lower stirring component 22, thus helping to improve the stirring effect of the equipment.

[0040] The upper stirring component 21 includes a first stirring blade 211, with a telescopic plate 212 slidably connected inside the first stirring blade 211. A crank connecting rod 213 is rotatably connected to the upper surface of the telescopic plate 212. A positioning plate 214 is movably connected to the end of the crank connecting rod 213 away from the telescopic plate 212, and the upper surface of the positioning plate 214 is fixedly connected to the matching pipe 20. The lower stirring component 22 includes a second stirring blade 221, with a moving plate 222 slidably connected inside the second stirring blade 221. A positioning support rod 223 is rotatably connected to the lower surface of the moving plate 222. A fixed sleeve 224 is movably connected to one end of the movable plate 222. A guide sleeve 225 is rotatably connected to the lower end of the fixed sleeve 224, and the lower surface of the guide sleeve 225 is fixedly connected to the partition plate 8. That is, during the up-and-down movement of the concentric rod 14, the stirring positions of the first stirring blade 211 and the second stirring blade 221 are constantly changing. When the concentric rod 14 moves upward, due to the restriction of the positioning plate 214, the positioning plate 214 drives the crank connecting rod 213 to push the telescopic plate 212, so that the telescopic plate 212 slides inside the first stirring blade 211. The lower fixed sleeve 224 pulls the moving plate 222 towards the interior of the second stirring blade 221 via the positioning support rod 223. As the telescopic plate 212 slides towards the exterior of the first stirring blade 211, the stirring radius at the upper end of the equipment is changed through the cooperation of the first stirring blade 211 and the telescopic plate 212. When the concentric rod 14 moves downwards, the fixed sleeve 224 drives the positioning support rod 223 to push the moving plate 222, causing the moving plate 222 to slide inside the second stirring blade 221. At this time, the upper positioning plate 214 is connected to the crank connecting rod 2... 13. Pull the telescopic plate 212 to slide into the interior of the first mixing blade 211. Thus, the mixing radius at the lower end of the equipment is changed by the cooperation between the second mixing blade 221 and the moving plate 222. Through the cooperation between the support rod 17 and the adjusting cylinder 10, the mixing radius and mixing position of the first mixing blade 211 and the second mixing blade 221 are continuously changed. Therefore, the mixing effect of the equipment is improved by changing the mixing radius and mixing position, which helps to make the concrete inside the equipment more uniform, improves the processing efficiency of the equipment, and solves the problem of uneven mixing in the equipment.

[0041] Example 2:

[0042] Existing equipment cannot effectively premix various materials when processing concrete, which directly affects the equipment's mixing efficiency and processing time, greatly increasing the production cost of concrete. Furthermore, during the mixing process, materials adhere to the inner wall of the equipment, resulting in some materials not being effectively mixed, which directly affects the uniformity and quality of the concrete mixture. Therefore, these problems urgently need to be solved.

[0043] The drive motor 9 drives the transmission shaft 11 inside the regulating cylinder 10 to rotate. The transmission shaft 11 drives the concentric rod 14 to rotate through the transmission plate 13. The concentric rod 14 drives the matching tube 20 to rotate through the upper transmission plate 19, causing the matching tube 20 to rotate circumferentially inside the cross 23. As the matching tube 20 rotates, it drives the premixing mechanism 24 to rotate as a whole. The premixing mechanism 24 includes a spiral shaft 25. The end of the spiral shaft 25 away from the limiting sleeve 26 is fixedly connected to the matching tube 20. The limiting sleeve 26 is sleeved on the outside of the end of the spiral shaft 25 away from the matching tube 20. The supporting shaft 27 is rotatably connected to the inner surface of the outer surface of the limiting sleeve 26. The gear plate 28 is fixedly connected to the end of the supporting shaft 27 away from the limiting sleeve 26. The outer surface of the gear plate 28 is meshed with an annular toothed plate 29. The premixing plate 3 is sleeved on the outside of the supporting shaft 27. 0. A funnel plate 31 is fixedly connected to one side of the annular toothed plate 29, and the funnel plate 31 is fixedly connected to the upper cover plate 3. When the matching pipe 20 drives the spiral shaft 25 to rotate inside the funnel plate 31, the spiral shaft 25 feeds the material on one hand and premixes the material on the other. With the rotation of the spiral shaft 25, the spiral shaft 25 drives the external limiting sleeve 26 to rotate, so that the limiting sleeve 26 drives the support shaft 27 to rotate synchronously, so that the support shaft 27 drives the gear plate 28 to roll on the annular toothed plate 29. Through the transmission between the gears, the gear plate 28 drives the support shaft 27 to rotate on its own axis. Therefore, the support shaft 27 rotates and rotates on its own axis at the same time, so that the support shaft 27 drives the external premixing plate 30 to stir and mix the various materials entering the funnel plate 31, which helps to improve the processing efficiency of the equipment for concrete and at the same time reduce the processing time of the equipment.

[0044] When the spiral shaft 25 rotates, it drives the external cleaning mechanism 32 to work. The cleaning mechanism 32 includes a transmission gear plate 33, which is located outside the spiral shaft 25 and is fixedly connected to it. A transmission wheel 34 is meshed on the outer surface of the transmission gear plate 33. The transmission wheel 34 is located above the cross 23 and is fixedly connected to the reciprocating screw 35. The reciprocating screw 35 is inserted inside the transmission wheel 34. The lower end of the reciprocating screw 35 passes through the interior of the guide slide plate 36 and is rotatably connected to the partition plate 8. The end of the reciprocating screw 35 above the partition plate 8 is sleeved with the guide slide plate 36. A movable push plate 37 is sleeved on the outside of the guide slide plate 36. That is, the spiral shaft 25 drives its external transmission gear plate 33 to rotate. Through the transmission between gears, the transmission gear plate 33 drives the transmission wheel 34 to rotate. The transmission wheel 34 drives the reciprocating screw 35 to rotate inside the cross 23, causing the guide slide plate 36 outside the reciprocating screw 35 to move up and down. During the movement, the guide slide plate 36 drives the moving push plate 37 to clean and push the material attached to the inner wall of the equipment, pushing the material on the inner wall towards the center so that the material can be fully mixed. Through the cooperation between the premixing mechanism 24 and the cleaning mechanism 32, the premixing effect of various materials can be achieved, as well as the cleaning and pushing effect of the material attached to the inner wall of the equipment. This greatly speeds up the processing time of the equipment, helps to improve the mixing uniformity of the equipment, and solves the problems of long processing time and incomplete mixing of materials on the inner wall in traditional equipment.

[0045] The working process and principle of this invention are as follows:

[0046] When mixing concrete, sand, cement, and water are added to the equipment in a certain proportion. The sand and cement are fed into the equipment from the feed hopper 4. Before feeding, the external power supply is controlled to start the drive motor 9. The drive motor 9 drives the transmission shaft 11 inside the regulating cylinder 10 to rotate. The transmission shaft 11 drives the concentric rod 14 to rotate synchronously through the transmission plate 13. The concentric rod 14 drives the support rod 17 on the positioning sleeve 15 to rotate synchronously. The support rod 17 drives the ball bearings 18 to roll on the regulating cylinder 10. Through the cooperation of the support rod 17 and the regulating cylinder 10, the concentric rod 14 moves up and down intermittently inside the support base plate 1, continuously changing the mixing position of the upper mixing component 21 and the lower mixing component 22, thus helping to improve the mixing effect of the equipment. When the concentric rod 14 moves upward, due to the fixed... The positioning plate 214 restricts the movement of the positioning plate 214, which drives the crank connecting rod 213 to push the telescopic plate 212, causing the telescopic plate 212 to slide inside the first mixing blade 211. At the same time, the lower fixed sleeve 224 pulls the moving plate 222 into the second mixing blade 221 through the positioning support rod 223. Thus, the mixing radius at the upper end of the equipment is changed by the cooperation between the first mixing blade 211 and the telescopic plate 212, and vice versa. Through the cooperation between the support rod 17 and the adjusting cylinder 10, the mixing radius and mixing position of the first mixing blade 211 and the second mixing blade 221 are continuously changed. Therefore, the mixing effect of the equipment is improved by changing the mixing radius and mixing position, which helps to make the concrete inside the equipment more uniform, improves the processing efficiency of the equipment, and solves the problem of uneven mixing in the equipment.

[0047] Furthermore, the concentric rod 14 drives the matching pipe 20 to rotate via the upper transmission plate 2 19, causing the matching pipe 20 to rotate circumferentially inside the cross 23. This, in turn, causes the matching pipe 20 to drive the spiral shaft 25 to rotate inside the funnel plate 31. The spiral shaft 25 simultaneously inputs and premixes the material. The spiral shaft 25 also drives the support shaft 27 on the limiting sleeve 26 to rotate. The support shaft 27 then drives the gear plate 28 to roll on the annular gear plate 29. Through the transmission between the gears, the gear plate 28 drives the support shaft 27 to rotate. Therefore, the support shaft 27 rotates and rotates simultaneously, causing the external premixing plate 30 to mix the various materials entering the funnel plate 31. This helps improve the equipment's efficiency in processing concrete while reducing... The equipment reduces processing time. Through gear transmission, the transmission wheel 34 drives the reciprocating screw 35 to rotate inside the cross 23, causing the guide slide plate 36 outside the reciprocating screw 35 to move up and down. During the movement, the guide slide plate 36 drives the moving push plate 37 to clean and push the material attached to the inner wall of the equipment, pushing the material on the inner wall towards the center so that the material can be fully mixed. Through the cooperation between the premixing mechanism 24 and the cleaning mechanism 32, it can achieve both the effect of premixing various materials and the effect of cleaning and pushing the material attached to the inner wall of the equipment, which greatly speeds up the processing time of the equipment, helps to improve the mixing uniformity of the equipment, and solves the problems of long processing time and incomplete mixing of inner wall materials in traditional equipment.

6. A method of using a concrete mixing device for water conservancy projects, wherein the method of use applies to the concrete mixing device for water conservancy projects as described in claim 5, characterized in that, The method of using this concrete mixing device for water conservancy projects includes the following steps: Step 1: When mixing concrete, sand, cement and water are put into the equipment in a certain proportion. Sand and cement are put into the equipment from the feed hopper (4) and water enters the equipment from the water inlet pipe (6). Before feeding, the external power supply is controlled to start the drive motor (9). Step 2: Drive the transmission shaft (11) inside the regulating cylinder (10) to rotate via the drive motor (9). The transmission shaft (11) drives the concentric rod (14) to rotate via the first transmission plate (13). The concentric rod (14) drives the matching tube (20) to rotate via the second transmission plate (19) at the upper end. This causes the matching tube (20) to drive the spiral shaft (25) to rotate inside the funnel plate (31). The spiral shaft (25) inputs the material on one hand and premixes the material on the other. In addition, the spiral shaft (25) drives the support shaft (27) on the limiting sleeve (26) to rotate. This causes the support shaft (27) to drive the gear plate (28) to roll on the ring tooth plate (29). This causes the support shaft (27) to rotate and rotate on its own. This causes the support shaft (27) to drive the premix plate (30) to stir and mix the material, which helps to improve the equipment's processing efficiency for concrete. Step 3: When the spiral shaft (25) rotates, the spiral shaft (25) drives its external transmission gear plate (33) to rotate. Through the transmission between gears, the transmission gear plate (33) drives the transmission wheel (34) to rotate. The transmission wheel (34) drives the reciprocating screw (35) to rotate inside the cross (23), causing the guide plate (36) outside the reciprocating screw (35) to move up and down. During the movement, the guide plate (36) drives the moving push plate (37) to clean and push the inner wall of the equipment, pushing the material on the inner wall towards the middle and improving the mixing uniformity. Step 4: As the concentric rod (14) rotates, the concentric rod (14) drives the support rod (17) on the positioning sleeve (15) to rotate synchronously. The support rod (17) drives the ball (18) to roll on the adjusting cylinder (10). Through the cooperation between the support rod (17) and the adjusting cylinder (10), the concentric rod (14) moves up and down intermittently inside the support base plate (1), thereby continuously changing the stirring position of the upper stirring component (21) and the lower stirring component (22) and improving the stirring efficiency. During the up-and-down movement of the concentric rod (14), when moving upward, it is restricted by the positioning plate (214), and the crank connecting rod (213) pushes the telescopic plate (212) to slide to the outside of the first stirring blade (211), thus changing the stirring radius at the upper end of the equipment. When moving downward, it is restricted by the fixed sleeve (224), and the positioning support rod (223) pushes the moving plate (222) to slide to the outside of the second stirring blade (221), thus changing the stirring radius at the lower end of the equipment. Since the telescopic plates (212) and the moving plate (222) at the upper and lower ends move in opposite directions, the stirring radius is continuously changed to improve the stirring efficiency of the equipment. Step 5: Feeding. During the feeding process, add the corresponding water so that the water enters the equipment directly from the water inlet pipe (6), and the processed concrete is discharged from the discharge pipe (5) for use.
