Description

Technical Field

[0001] This invention relates to the field of concrete production technology, and in particular to an integrated crushing, grinding and mixing device and method for concrete production. Background Technology

[0002] Concrete is made by crushing raw materials such as sand and stone to a certain degree to meet relevant standards, and then fully mixing them with cement and other materials in a certain proportion. The main quality indicators of concrete include workability, strength, deformation, and durability. Many factors influence these indicators, such as the quality of the raw materials, the particle size after crushing, and the proportion of raw materials. Therefore, the crushing and mixing of raw materials is crucial in the concrete production process. However, existing integrated crushing and mixing devices for concrete raw materials, while possessing both crushing and mixing functions, have reduced crushing and mixing effects compared to traditional dedicated equipment. This is detrimental to concrete production and quality improvement, highlighting its shortcomings. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated crushing, grinding and mixing device and method for concrete production, so as to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An integrated crushing, grinding, and mixing device for concrete production includes an upper cylinder, a lower cylinder, a controller, a reducer, a drive motor, an upper transmission shaft, an upper guide hopper, a lower guide hopper, a grinding disc, an upper hollow shaft, a transmission arm, a crushing blade, a transmission disc, a grinding roller, a lower hollow shaft, a fixed gear, a drive shaft, a driven shaft, a moving gear, a mixing section, and a feeding section. The lower cylinder is vertically fixed to the bottom of the upper cylinder, and the controller and reducer are fixed to its top. A vertical drive motor is fixed to the top of the reducer. The drive motor's shaft is coaxially connected to the reducer's input shaft. The reducer's output shaft is coaxially fixed to the upper transmission shaft, which is interlocked within the upper cylinder. The upper guide hopper, lower guide hopper, and grinding disc are sequentially fixed to the inner wall of the upper cylinder from top to bottom. The upper drive shaft has a hollow shaft coaxially fixed to its upper part and a radial drive arm fixed to its bottom. Multiple radial crushing blades are fixed to the outer wall of the hollow shaft. A drive disc is coaxially fixed to the bottom of the upper drive shaft. Multiple grinding rollers inclined downwards are rotatably connected to the outer circumference of the drive disc. A vertical hollow shaft is fixed to the middle of the lower guide hopper. The hollow shaft is coaxially rotatably connected to the upper drive shaft, and a fixed gear is coaxially fixed to its outer wall. A vertical drive shaft is rotatably connected to the drive arm. A driven shaft inclined downwards is rotatably connected to the outside of the drive disc. A moving gear is coaxially fixed to the upper part of the drive shaft and is connected to the driven shaft via a universal joint. A mixing section is installed inside the lower cylinder, and a feeding section is installed together with the upper cylinder.

[0006] Based on the above technical solution, the mixing part includes an upper support, a lower support, a transmission ball, a swing disk, paddles, an upper guide cylinder, a lower guide cylinder, a lower transmission shaft, an auger, a discharge cylinder, a support frame, a lower electromagnetic shut-off valve, a water inlet pipe, and an upper electromagnetic shut-off valve. The grinding disk is fixed to the bottom of the upper support, and the lower support is fixed to the bottom of the inner wall of the lower cylinder. The upper and lower supports are rotatably connected to the transmission ball. The outer wall of the transmission ball is fixed to the swing disk. Multiple paddles are fixed at equal angles around the top and bottom of the swing disk, and multiple upper and lower guide cylinders are fixed at equal angles around the circumference. The driven shaft is fixed to the bottom of the lower transmission shaft. An auger is coaxially fixed to the upper part of the lower transmission shaft. A vertical discharge cylinder is fixed to the bottom of the lower cylinder, and a vertical support frame is fixed to the outer wall. The lower transmission shaft is rotatably connected to the upper part of the lower cylinder. The discharge cylinder is equipped with a lower electromagnetic shut-off valve. A horizontal water inlet pipe is fixed to the upper part of the lower cylinder, and an upper electromagnetic shut-off valve is installed on the water inlet pipe.

[0007] Based on the above technical solution, the feeding section includes a main feeding cylinder, a secondary feeding cylinder, a main feeding port, a secondary feeding port, a feeding piston, a support rod, rollers, an upper dustproof cylinder, and a lower dustproof cylinder. Multiple vertical main feeding cylinders are fixed at equal angles along the circumference of the outer wall of the upper cylinder. A secondary feeding cylinder is fixed to the outside of each main feeding cylinder. The bottom of each main feeding cylinder is closed from top to bottom, and the upper part of each main feeding cylinder shares a main feeding port with the upper cylinder. The upper part of each secondary feeding cylinder is closed from bottom to top, and its bottom is connected to the main feeding cylinder. The main feeding cylinders are connected by a secondary feeding port. Each main feeding cylinder is slidably connected to a vertical feeding piston. Each feeding piston has a vertical support rod fixed at its bottom end, and its top end is inclined upwards towards the lower middle part of the cylinder. Each support rod has a roller rotatably connected to its bottom end and is slidably connected to the lower cylinder. The bottom end of the lower guide hopper is fixed with a vertical upper dustproof cylinder, and the top end of the transmission disc is fixed with a vertical lower dustproof cylinder. The upper dustproof cylinder and the lower dustproof cylinder are rotatably connected in a sealed manner.

[0008] Based on the above technical solution, the upper guide hopper is funnel-shaped, the lower guide hopper is inverted funnel-shaped, the fixed gear meshes with the moving gear, the swing disk is radially arranged relative to the driven shaft, the upper guide cylinder is smaller at the top and larger at the bottom, and the lower guide cylinder is larger at the top and smaller at the bottom. The rollers constantly roll and rub against the top of the swing disk under the action of gravity. The controller, drive motor, lower solenoid shut-off valve, and upper solenoid shut-off valve are electrically connected. The controller is connected to an external power source. When the drive motor is energized and rotates, it can drive the upper transmission shaft to rotate through the reducer. When the upper transmission shaft rotates, it can drive the upper hollow... The shaft, transmission arm, and transmission disc rotate. When the transmission arm rotates, the meshing of the moving gear and the fixed gear enables the drive shaft to rotate and move circumferentially at the same time. When the drive shaft rotates and moves circumferentially at the same time, it can drive the driven shaft to rotate and swing circumferentially at the same time through the universal joint. When the driven shaft rotates and swings circumferentially at the same time, it can drive the swing disc to rotate and swing circumferentially at the same time. When the driven shaft rotates and swings circumferentially at the same time, it can drive the lower transmission shaft and the auger to rotate. When the swing disc rotates and swings circumferentially at the same time, it can cause each support rod to move up and down along the lower cylinder through the rollers.

[0009] Compared with the prior art, the present invention has the following advantages: The present invention controls the rotation of the drive motor, which enables the swing disk to rotate and oscillate circumferentially, causing the crushing blade and auger to rotate, and the grinding roller to move circumferentially. The circumferentially oscillating swing disk allows the feeding piston to slide up and down reciprocally within the main feeding cylinder, thereby achieving intermittent feeding. This ensures that each feeding material is crushed in a timely manner, guaranteeing the crushing effect. The rotating crushing blade and the circumferentially moving grinding roller crush and grind the material, ensuring the crushing effect and ensuring that the particle size meets the requirements. The swing disk, which oscillates and rotates circumferentially, can fully compress, mix, and stir the material. Furthermore, the upper guide cylinder, lower guide cylinder, and auger can guide the material flow more fully, thereby ensuring the mixing effect, thus guaranteeing the quality of concrete and facilitating concrete production.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-4 As shown, an integrated crushing, grinding, and mixing device for concrete production includes an upper cylinder 1, a lower cylinder 2, a controller 3, a reducer 4, a drive motor 5, an upper transmission shaft 6, an upper guide bucket 7, a lower guide bucket 8, a grinding disc 9, an upper hollow shaft 10, a transmission arm 11, a crushing blade 12, a transmission disc 13, a grinding roller 14, a lower hollow shaft 15, a fixed gear 16, a drive shaft 17, a driven shaft 18, a moving gear 19, a mixing section 20, and a feeding section 21. The lower cylinder 2 is vertically fixed to the bottom of the upper cylinder 1, and the top... A controller 3 and a reducer 4 are fixed at one end. A vertical drive motor 5 is fixed at the top of the reducer 4. The shaft of the drive motor 5 is coaxially connected to the input shaft of the reducer 4. An upper transmission shaft 6 is coaxially fixed to the output shaft of the reducer 4. The upper transmission shaft 6 is interposed and inserted into the upper cylinder 1. An upper guide bucket 7, a lower guide bucket 8, and a grinding disc 9 are fixed sequentially from top to bottom on the inner wall of the upper cylinder 1. The upper guide bucket 7 is used to guide the material to move towards the crushing blade 12 for easy crushing. The lower guide bucket... 8 is used to guide the pulverized material to move towards the grinding disc 9, so that the pulverized material can be further pulverized by the grinding disc 9 and the grinding roller 14. The upper drive shaft 6 is coaxially fixed with an upper hollow shaft 10 at the top and a radial drive arm 11 is fixed at the bottom. Multiple radial pulverizing blades 12 are fixed on the outer wall of the upper hollow shaft 10. The bottom of the upper drive shaft 6 is coaxially fixed with a drive disc 13. Multiple grinding rollers 14 inclined downwards are rotatably connected to the outer circumference of the drive disc 13. The lower guide bucket 8 is fixed in the middle. There is a vertical lower hollow shaft 15, which is coaxially rotatably connected to the upper transmission shaft 6, and a fixed gear 16 is coaxially fixed on its outer wall. The transmission arm 11 is rotatably connected to a vertical drive shaft 17. The external transmission disk 13 is rotatably connected to a driven shaft 18 that is inclined downwards. A moving gear 19 is coaxially fixed on the upper part of the drive shaft 17, and is connected to the driven shaft 18 through a universal joint. The lower cylinder 2 is equipped with a mixing part 20, and together with the upper cylinder 1, a feeding part 21 is installed.

[0017] The mixing section 20 includes an upper support 22, a lower support 23, a transmission ball 24, a swing disk 25, a paddle 26, an upper guide cylinder 27, a lower guide cylinder 28, a lower transmission shaft 29, an auger 30, a discharge cylinder 31, a support frame 32, a lower electromagnetic shut-off valve 33, a water inlet pipe 34, and an upper electromagnetic shut-off valve 35. The grinding disk 9 has the upper support 22 fixed to its bottom end, and the lower support 23 is fixed to the bottom end of the inner wall of the lower cylinder 2. The upper support 22 and the lower support 23 are rotatably connected to the transmission ball 24. The swing disk 25 is fixed to the outer wall of the transmission ball 24. The top and bottom ends of the swing disk 25 are... Multiple paddles 26 are fixed at equal angles around the circumference, and multiple upper guide cylinders 27 and lower guide cylinders 28 are fixed at equal angles around the circumference. A lower drive shaft 29 is fixed to the bottom of the driven shaft 18, and an auger 30 is coaxially fixed to the upper part of the lower drive shaft 29. A vertical discharge cylinder 31 is fixed to the bottom end of the lower cylinder 2, and a vertical support frame 32 is fixed to the outer wall. The lower drive shaft 29 is rotatably connected to the upper part of the lower cylinder 2. A lower electromagnetic shut-off valve 33 is installed on the discharge cylinder 31. A horizontal water inlet pipe 34 is fixed to the upper part of the lower cylinder 2, and an upper electromagnetic shut-off valve 35 is installed on the water inlet pipe 34.

[0018] The feeding section 21 includes a main feeding cylinder 36, a secondary feeding cylinder 37, a main feeding port 38, a secondary feeding port 39, a feeding piston 40, a support rod 41, a roller 42, an upper dustproof cylinder 43, and a lower dustproof cylinder 44. Multiple vertical main feeding cylinders 36 are fixed at equal angles around the outer circumference of the upper cylinder 1. A secondary feeding cylinder 37 is fixed to the outside of each main feeding cylinder 36. The bottom of each main feeding cylinder 36 is closed from the top, and the upper part of the main feeding cylinder 36 is connected to the upper cylinder 1 via the main feeding port 38. The upper part of each secondary feeding cylinder 37 is closed from the bottom, and the bottom of the secondary feeding cylinder 37 is connected to the main feeding cylinder 36 via the secondary feeding port 39. Each main feeding cylinder 36 is slidably connected to a vertical feeding piston 40 at the top and bottom. The bottom of the feeding piston 40 is fixed with vertical support rods 41, and the tops of the rods are inclined to the lower middle part of the upper cylinder 1. This facilitates the temporary storage of raw materials flowing into the main feeding cylinder 36 from the auxiliary feeding port 39 and facilitates their discharge from the main feeding port 38 into the feeding cylinder 1. The bottom of each support rod 41 is rotatably connected to a roller 42, which is slidably connected to the lower cylinder 2. The bottom of the lower guide bucket 8 is fixed with a vertical upper dustproof cylinder 43, and the top of the transmission disc 13 is fixed with a vertical lower dustproof cylinder 44. The upper dustproof cylinder 43 and the lower dustproof cylinder 44 are rotatably connected in a sealed manner, thereby protecting the fixed gear 16, the moving gear 19 and the universal joint from contamination by raw materials and ensuring the stability of the transmission.

[0019] The upper guide hopper 7 is funnel-shaped, and the lower guide hopper 8 is inverted funnel-shaped. The fixed gear 16 meshes with the moving gear 19. The swing disk 25 is radially arranged relative to the driven shaft 18. The upper guide cylinder 27 is smaller at the top and larger at the bottom, so that the swing disk 25 can easily gather the material and guide it upward when squeezing it. The lower guide cylinder 28 is larger at the top and smaller at the bottom, so that the swing disk 25 can easily gather the material and guide it downward when squeezing it. The roller 42 always rolls and rubs against the top of the swing disk 25 under the action of gravity. The controller 3, drive motor 5, lower solenoid shut-off valve 33 and upper solenoid shut-off valve 35 are electrically connected. The controller 3 is connected to an external power supply. When the drive motor 5 is energized and rotates, it passes through the reducer 4. The upper drive shaft 6 can be driven to rotate. When the upper drive shaft 6 rotates, it can drive the upper hollow shaft 10, the drive arm 11 and the drive disc 13 to rotate. When the drive arm 11 rotates, the meshing of the moving gear 19 and the fixed gear 16 can make the drive shaft 17 rotate and move circumferentially at the same time. When the drive shaft 17 rotates and moves circumferentially at the same time, it can drive the driven shaft 18 to rotate and swing circumferentially at the same time through the universal joint. When the driven shaft 18 rotates and swings circumferentially at the same time, it can drive the swing disc 25 to rotate and swing circumferentially at the same time. When the driven shaft 18 rotates and swings circumferentially at the same time, it can drive the lower drive shaft 29 and the auger 30 to rotate. When the swing disc 25 rotates and swings circumferentially at the same time, it can make each support rod 41 move up and down along the lower cylinder 2 through the roller 42.

[0020] The method for crushing, grinding, and mixing concrete using this invention is as follows: During use, raw materials are fed into the auxiliary upper feed cylinder 37 via a pipeline, and water is fed into the water inlet pipe 34 via a pipeline. The controller 3 controls the drive motor 5 to rotate. The drive motor 5, through the reducer 4, drives the upper transmission shaft 6 to rotate slowly. When the upper transmission shaft 6 rotates, it drives the upper hollow shaft 10, the transmission arm 11, and the transmission disc 13 to rotate. During rotation, the transmission arm 11 drives the upper transmission shaft 6 to move circumferentially. When the upper transmission shaft 6 moves circumferentially, the meshing of the fixed gear 16 and the moving gear 19 drives the drive shaft 17 to rotate. When the drive shaft 17 moves and rotates circumferentially, it drives the driven shaft 18, transmission ball 24, and swing disk 25 to swing and rotate circumferentially through a universal joint. The driven shaft 18, while swinging and rotating circumferentially, drives the lower transmission shaft 29 and auger 30 to rotate. When the swing disk 25 swings circumferentially, it drives the support rod 41 and the feeding piston 40 to move up and down reciprocally through the roller 42. As the feeding piston 40 slides up and down within the main feeding cylinder 36, it moves back and forth between below the auxiliary feeding port 39 and below the main feeding port 38, allowing the raw material to fall through the auxiliary feeding port 39 under gravity. The material is fed through the top of the feeding piston 40 and then pushed upwards through the main feeding port 38 into the upper cylinder 1, thus achieving alternating and intermittent feeding. After entering the upper cylinder 1, the material is cut and crushed by the crushing blades 12 that rotate with the upper hollow shaft 10. The crushed material is then guided by the upper guide bucket 7 and the lower guide bucket 8 and falls into the grinding disc 9. The rotating transmission disc 13 drives the grinding roller 14 to move circumferentially, thereby cooperating with the grinding disc 9 to grind the crushed material and improve the crushing effect. The ground material enters the lower cylinder 2, and the upper electromagnetic shut-off valve 35 is opened at the appropriate time to lower the material into the lower cylinder 2. During internal water supply, the oscillating disc 25, which rotates and swings circumferentially, can use the paddle 26 to stir and mix the mixture, and can also squeeze the mixture up and down to make it more thoroughly mixed. The upper guide cylinder 27 and the lower guide cylinder 28 can cause the mixture to gather during the squeezing process of the oscillating disc 25 and then flow out through it, thereby improving the mixing effect. The rotating auger 30 can tumble the mixture up and down to make the mixing more thorough. After stopping the material supply to the auxiliary feed cylinder 37 and allowing the raw materials to mix and stir for a certain period of time, the lower electromagnetic shut-off valve 33 can be opened to discharge the concrete.

[0021] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
