Description

Technical Field

[0001] This invention relates to the field of mixer technology, specifically to a mixing device with a cleaning function. Background Technology

[0002] Concrete, generally speaking, refers to cement concrete, which is made by mixing cement as a binder, sand and stone as aggregates, and water in a certain proportion, and then mixing, molding and curing it. It is also called ordinary concrete and is widely used in civil engineering.

[0003] Concrete mixing is an operation method that mixes and stirs materials such as cement, lime, and water until they are uniform. There are two types of concrete mixing: manual mixing and mechanical mixing. Concrete mixing equipment is widely used in construction projects in my country's industry, agriculture, transportation, national defense, water conservancy, and municipal sectors, and the demand is constantly increasing.

[0004] Existing mixing equipment lacks cleaning functions, often leaving concrete residue in the mixing tank, resulting in waste. Furthermore, the water pressure during the mixing process cannot be adjusted in real time according to the amount of material added, and it cannot be sprayed evenly onto the surface of sand and gravel. In addition, uneven mixing can occur.

[0005] Therefore, a self-cleaning and real-time adjustable stirring device is needed to meet the requirements. Summary of the Invention

[0006] The purpose of this invention is to provide a stirring device with a cleaning function to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A mixing device with cleaning function includes a pre-mixing bin, a mixing bin, a base, a water supply mechanism, and a controller. The pre-mixing bin is fixedly connected to the mixing bin and is located above the mixing bin. The pre-mixing bin and the mixing bin are in communication. The base is fixedly connected to the mixing bin. The water supply mechanism is fixedly connected to the mixing bin. The controller is fixedly connected to the mixing bin. The pre-mixing bin includes a cylinder, a drive motor, a stirring shaft, and a rotating blade. The cylinder is fixedly connected to the mixing bin. The drive motor is fixedly connected to the cylinder. The stirring shaft is driven by the output shaft of the drive motor. The rotating blade is fixedly connected to the stirring shaft. The mixing bin includes a rotating motor, a rotating shaft, stirring blades, a scraper, and a tank. The rotating motor is fixedly connected to the tank. The rotating shaft is fixedly connected to the output shaft of the rotating motor. The stirring blades are driven by the rotating shaft with a gap. The scraper is fixedly connected to the rotating shaft. The shape of the scraper fits the shape of the tank. The tank is fixedly connected to the base.

[0008] The base is placed on the ground, providing a stable working platform for the mixing device. Cement and sand are pre-mixed in the pre-mixing hopper to ensure a more uniform mixture, thereby improving concrete quality and facilitating subsequent mixing. The pre-mixing hopper is installed above the mixing hopper to facilitate the entry of the mixed cement and sand. The water supply mechanism provides the appropriate amount of water to the mixing device. The controller is used to control each mechanism. The drive motor provides power to the mixing shaft. When the drive motor starts, it drives the mixing shaft to rotate, which in turn drives the rotating blades fixed on the mixing shaft. The rotating blades mix the cement and sand. The rotating motor provides power to the rotating shaft, which in turn drives the mixing blades fixed to the rotating shaft to rotate. The rotating blades mix the pre-mixed cement, sand, gravel, and water together to form concrete. The scraper blades are in contact with the tank body and rotate under the drive of the rotating shaft. They can scrape off the concrete adhering to the tank body, preventing concrete from sticking to the inner wall of the tank and causing waste, and cleaning the tank body.

[0009] Furthermore, the inlet of the premixing bin is funnel-shaped, and the premixing bin also includes a material gate mechanism, which is fastened to the cylinder body. The cylinder body is provided with a movable cavity, which is located at the connection between the premixing bin and the mixing bin. The material gate mechanism includes a hydraulic push rod and a snap-fit ​​plate. The hydraulic push rod is fastened to the cylinder body, the snap-fit ​​plate is fastened to the hydraulic push rod, and the snap-fit ​​plate is slidably connected to the cylinder body. The hydraulic push rod and the snap-fit ​​plate are located inside the movable cavity.

[0010] The funnel-shaped inlet facilitates the entry of the mixed material. The material gate mechanism is used to close the channel between the premixing bin and the mixing bin, providing a working chamber for premixing. After premixing is completed, the material gate mechanism opens, and the mixed cement and yellow sand fall into the mixing bin. Two hydraulic push rods push two clamping plates to move relative to each other. The two clamping plates fit together, closing the channel between the premixing bin and the mixing bin. The front ends of the two clamping plates cooperate with each other to ensure a tight closure and prevent material leakage.

[0011] Furthermore, a feed pipe is provided on one side of the mixing chamber, and a water supply mechanism is located below the feed pipe. The water supply mechanism includes a water tank, a water pump, and a water supply pipe. The water tank is securely connected to the tank body, the water pump is securely connected to the water tank, the water supply pipe is connected to the outlet of the water pump, and the outlet of the water supply pipe is connected to the tank body.

[0012] The water supply system is based on the tank. When the stones enter through the feed pipe, the water pump starts and introduces water from the tank into the tank through the water supply pipe. The outlet of the water supply pipe is located below the outlet of the feed pipe, so that the water can be sprayed onto the surface of the stones to pre-wet them, making it easier for the stones to bond with the cement.

[0013] Furthermore, the feed pipe includes a pipe body, a moving rod, and a spring. The pipe body is fastened to the tank body, the moving rod is slidably connected to the pipe body, one end of the spring is fastened to the moving rod, and the other end of the spring is fastened to the pipe body.

[0014] When stones enter the feed pipe, the amount of stone entering will inevitably fluctuate. As the amount of stone entering increases, the weight of the stone flowing per unit time increases, which in turn increases the downward pressure on the moving rod. When the stone passes the moving rod, the moving rod is subjected to pressure under the action of the stone's gravity, which in turn compresses the spring. The moving rod slides down along the channel on the pipe body. The heavier the stone, the longer the moving rod moves down.

[0015] Furthermore, the water supply pipe has an opening, through which the moving rod is inserted into the water supply pipe. The water supply mechanism also includes a sealing ring, which is located at the opening of the water supply pipe and is securely connected to the water supply pipe. The moving rod is slidably connected to the sealing ring.

[0016] When the moving rod is pressed into the water supply pipe, it changes the flow cross-section of the water supply pipe, thereby adjusting the water pressure. The more stones that enter, the heavier they are, the longer the moving rod is inserted into the water supply pipe, the smaller the flow cross-section, and the greater the water pressure in the water supply pipe. Therefore, the farther the water flows from the water supply pipe into the tank, the more evenly the stones are sprayed. The fewer stones that enter, the more evenly the water pressure is adjusted. The water pressure can be automatically adjusted by changing the length of the moving rod inserted into the water supply pipe, and the sealing ring prevents water from flowing out.

[0017] Furthermore, the mixing chamber also includes a detector, which is fixedly connected to the mixing blade. The detector is located on the mixing blade at one end away from the rotation axis. The detector includes a housing, a pressure strain gauge, and a slider. The housing is fixedly connected to the mixing blade, the pressure strain gauge is fixedly connected to the housing and is located inside the housing, the slider is slidably connected to the housing, and the pressure strain gauge is electrically connected to the controller.

[0018] The detector is used to detect the rotation speed of the mixing blade. The faster the mixing blade rotates, the greater the centrifugal force on the detector fixed to the mixing blade. Under the action of centrifugal force, the slider will move towards the pressure strain gauge, thus applying pressure to the pressure strain gauge. The pressure strain gauge deforms under pressure, and its resistance decreases. The controller determines the rotation speed of the mixing blade by analyzing the change in the resistance of the pressure strain gauge. The smaller the resistance of the pressure strain gauge, the faster the rotation speed of the mixing blade, and vice versa. When the resistance of the concrete on the mixing blade is greater than the friction between the mixing blade and the rotating shaft, it indicates that the concrete at that point is too viscous, and the mixing blade stops rotating. At this time, the resistance of the pressure strain gauge is at its maximum.

[0019] Furthermore, the rotating shaft is provided with a first channel, a second channel, and a valve assembly. The mixing chamber also includes a plunger pump, which is fastened to the rotating shaft and located at the top of the rotating shaft. The inlet of the plunger pump is connected to the first channel, and the outlet of the plunger pump is connected to the second channel. The valve assembly is located at the inlet of the first channel and the outlet of the second channel.

[0020] When the mixing blades of a certain layer stop rotating, it indicates that the concrete in that layer is relatively viscous and has a low moisture content. The controller can detect the signal by the change in resistance of the pressure strain gauge in the detector and control the plunger pump to start. The corresponding valve assembly opens, drawing in concrete from other layers through the first channel and discharging the concrete with higher moisture content to the lower moisture content position through the second channel. Because the rotating shaft is constantly rotating, when the concrete with higher moisture content is discharged from the outlet of the second channel, it will be discharged in a spiral, so that the concrete with lower moisture content and the concrete with higher moisture content are mixed evenly, improving the mixing efficiency.

[0021] Furthermore, the stirring blade includes a first blade, a second blade, and a third blade, and the valve assembly includes solenoid valve a, solenoid valve b, solenoid valve c, solenoid valve d, solenoid valve e, and solenoid valve f. Solenoid valve a, solenoid valve b, and solenoid valve c are located in the first channel, and solenoid valve d, solenoid valve e, and solenoid valve f are located in the second channel.

[0022] There is a linkage between the mixing blades and the valve assembly. For example, when the second blade stops rotating due to the resistance of the concrete, the detector detects a signal and transmits it to the controller. The controller controls solenoid valves a, c, and e to open, while other valve assemblies close. The plunger pump starts to draw concrete from solenoid valves a and c and discharge it from solenoid valve e. This process can be repeated to adjust the viscosity of different layers of concrete, so that the overall viscosity of the concrete remains uniform.

[0023] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention utilizes scrapers that adhere to the tank body to achieve self-cleaning of the inner wall of the tank during the mixing process, thus assisting in concrete mixing and improving mixing efficiency. Pre-mixing cement and sand in the pre-mixing bin ensures a more uniform mixture, thereby improving concrete quality. The water supply mechanism and feed pipe work together to automatically adjust the length of the moving rod inserted into the water supply pipe based on the pressure exerted by the weight of the feed material, thereby adjusting the flow cross-section within the water supply pipe and achieving automatic water pressure regulation. This ensures thorough mixing of water and aggregates. The detector uses centrifugal force to determine the rotational speed of the mixing blades, thereby detecting the viscosity of different layers of concrete. The structure is simple, and the detection is rapid. Furthermore, a plunger pump transfers concrete with high moisture content to concrete with low moisture content, maintaining a uniform overall viscosity of the concrete and ensuring mixing quality.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0035] The present invention provides the following technical solution:

[0036] like Figure 1 , Figure 2 As shown, the mixing device with cleaning function includes a pre-mixing bin 1, a mixing bin 2, a base 3, a water supply mechanism 4, and a controller 5. The pre-mixing bin 1 is fixedly connected to the mixing bin 2, and the pre-mixing bin 1 is located above the mixing bin 2 and is connected to the mixing bin 2. The base 3 is fixedly connected to the mixing bin 2, the water supply mechanism 4 is fixedly connected to the mixing bin 2, and the controller 5 is fixedly connected to the mixing bin 2. The pre-mixing bin 1 includes a cylinder 11, a drive motor 12, a mixing shaft 13, and a rotating blade 14. The cylinder 11 is fixedly connected to the mixing bin 2, and the drive motor 12 is fixedly connected to the cylinder 11. 11. The stirring shaft 13 is connected to the output shaft of the drive motor 12. The rotating blade 14 is connected to the stirring shaft 13. The stirring chamber 2 includes a rotating motor 21, a rotating shaft 22, a stirring blade 23, a scraper 24, and a tank 25. The rotating motor 21 is connected to the tank 25. The rotating shaft 22 is connected to the output shaft of the rotating motor 21. The stirring blade 23 is connected to the rotating shaft 22 with a gap drive. The scraper 24 is connected to the rotating shaft 22. The shape of the scraper 24 fits the tank 25. The tank 25 is connected to the base 3.

[0037] The base 3 is placed on the ground, providing a stable working platform for the mixing device. Cement and sand are pre-mixed in the pre-mixing hopper 1 to ensure a more uniform mixture, thereby improving concrete quality and facilitating subsequent mixing. The pre-mixing hopper 1 is installed above the mixing hopper 2 to facilitate the entry of the mixed cement and sand into the mixing hopper 2. The water supply mechanism 4 provides the mixing device with an appropriate amount of water. The controller 5 controls each mechanism. The drive motor 12 provides power to the mixing shaft 13. When the drive motor 12 starts, it drives the mixing shaft 13 to rotate. The rotating blades fixed on the mixing shaft 13 drive the rotating blades 13 to mix cement and sand. The rotating motor 21 provides power to the rotating shaft 22, thereby driving the mixing blades 23 fixed to the rotating shaft 22 to rotate. The rotating blades 23 mix the pre-mixed cement, sand, gravel, and water together to form concrete. The scraper 24 is in contact with the tank 25 and rotates under the drive of the rotating shaft 22. It can scrape off the concrete adhering to the tank 25, preventing the concrete from adhering to the inner wall of the tank 25 and causing waste, and cleaning the tank 25.

[0038] like Figure 2 , Figure 4As shown, the inlet of the premixing bin 1 is funnel-shaped. The premixing bin 1 also includes a material gate mechanism 15, which is fastened to the cylinder 11. The cylinder 11 is provided with a movable cavity 111, which is located at the connection between the premixing bin 1 and the mixing bin 2. The material gate mechanism 15 includes a hydraulic push rod 151 and a snap-fit ​​plate 152. The hydraulic push rod 151 is fastened to the cylinder 11, and the snap-fit ​​plate 152 is fastened to the hydraulic push rod 151. The snap-fit ​​plate 152 is slidably connected to the cylinder 11. The hydraulic push rod 151 and the snap-fit ​​plate 152 are located in the movable cavity 111.

[0039] The funnel-shaped inlet facilitates the entry of the mixed material. The material gate mechanism 15 is used to close the channel between the premixing bin 1 and the mixing bin 2, providing a working chamber for premixing. After premixing is completed, the material gate mechanism 15 opens, and the mixed cement and yellow sand fall into the mixing bin 2. Two hydraulic push rods 151 push two snap-fit ​​plates 152 to move relative to each other. The two snap-fit ​​plates 152 fit together, closing the channel between the premixing bin 1 and the mixing bin 2. The front ends of the two snap-fit ​​plates 152 cooperate with each other to ensure a tight closure and prevent material leakage.

[0040] like Figure 1 , Figure 3 As shown, a feed pipe 26 is provided on one side of the mixing chamber 2, and a water supply mechanism 4 is located below the feed pipe 26. The water supply mechanism 4 includes a water tank 41, a water pump 42, and a water supply pipe 43. The water tank 41 is fixedly connected to the tank body 25, the water pump 42 is fixedly connected to the water tank 41, the water supply pipe 43 is connected to the outlet of the water pump 42, and the outlet of the water supply pipe 43 is connected to the tank body 25.

[0041] The water supply mechanism 4 is installed on the tank body 25. When the stones enter from the feed pipe 26, the water pump 42 starts and introduces the water in the water tank 41 into the tank body 25 through the water supply pipe 43. The outlet of the water supply pipe 43 is located below the outlet of the feed pipe 26, so that the water can be sprayed onto the surface of the stones to pre-wet the stones, making it easier for the stones to fuse with the cement.

[0042] like Figure 3 As shown, the feed pipe 26 includes a pipe body 261, a moving rod 262, and a spring 263. The pipe body 261 is fastened to the tank body 25, the moving rod 262 is slidably connected to the pipe body 261, one end of the spring 263 is fastened to the moving rod 262, and the other end of the spring 263 is fastened to the pipe body 261.

[0043] When stones enter the feed pipe 26, the amount of stone entering will inevitably fluctuate. As the amount of stone entering increases, the weight of the stone flowing per unit time increases, which increases the downward pressure on the moving rod 263. When the stone passes the moving rod 262, the moving rod 262 is subjected to pressure under the action of the stone's gravity, which in turn compresses the spring 263. The moving rod 262 slides downward along the channel on the pipe body 261. The heavier the stone, the longer the moving rod 262 moves downward.

[0044] like Figure 3 As shown, the water supply pipe 43 has an opening, and the moving rod 262 passes through the opening and is inserted into the water supply pipe 43. The water supply mechanism 4 also includes a sealing ring 44, which is located at the opening of the water supply pipe 43. The sealing ring 44 is fastened to the water supply pipe 43, and the moving rod 262 is slidably connected to the sealing ring 44.

[0045] When the movable rod 262 is inserted into the water supply pipe 43 under pressure, it changes the flow cross section of the water supply pipe 43, thereby adjusting the water pressure. The more stones that enter, the heavier they are, the longer the movable rod 262 is inserted into the water supply pipe 43, the smaller the flow cross section, and the greater the water pressure in the water supply pipe 43. Therefore, the farther the water flows from the water supply pipe 43 into the tank 25, the more evenly the stones are sprayed. The fewer stones that enter, the better. Conversely, by changing the length of the movable rod 262 inserted into the water supply pipe 43, the water pressure can be automatically adjusted. The sealing ring 44 prevents water from flowing out.

[0046] like Figure 5 , Figure 8 As shown, the mixing chamber 2 also includes a detector 28, which is fastened to the stirring blade 23. The detector 28 is located on the stirring blade 23 at the end away from the rotating shaft 22. The detector 28 includes a housing 281, a pressure strain gauge 282, and a slider 283. The housing 281 is fastened to the stirring blade 23, the pressure strain gauge 282 is fastened to the housing 281 and is located inside the housing 281, the slider 283 is slidably connected to the housing 281, and the pressure strain gauge 282 is electrically connected to the controller 5.

[0047] The detector 28 is used to detect the rotation speed of the stirring blade 23. The faster the stirring blade 23 rotates, the greater the centrifugal force on the detector 28 fixed on the stirring blade 23. Under the action of centrifugal force, the slider 283 will move towards the pressure strain gauge 282, thereby applying pressure to the pressure strain gauge 282. The pressure strain gauge 282 deforms under pressure, and its resistance decreases. The controller 5 determines the rotation speed of the stirring blade 23 by analyzing the change in the resistance of the pressure strain gauge 282. The smaller the resistance of the pressure strain gauge 282, the faster the rotation speed of the stirring blade 23, and vice versa. When the resistance of the stirring blade 23 to the concrete is greater than the friction between the stirring blade 23 and the rotating shaft 22, it indicates that the concrete at that point is too viscous, and the stirring blade 23 stops rotating. At this time, the resistance of the pressure strain gauge 282 is at its maximum.

[0048] like Figure 5 As shown, the rotating shaft 22 is provided with a first channel 221, a second channel 222 and a valve assembly 223. The mixing chamber 2 also includes a plunger pump 27, which is fastened to the rotating shaft 22. The plunger pump 27 is located at the top of the rotating shaft 22. The inlet of the plunger pump 27 is connected to the first channel 221 and the outlet of the plunger pump 27 is connected to the second channel 222. The valve assembly 223 is located at the inlet of the first channel 221 and the outlet of the second channel 222.

[0049] When the mixing blade 23 of a certain layer stops rotating, it indicates that the concrete in that layer is relatively viscous and has a low moisture content. The controller 5 can detect the signal by the change in resistance of the pressure strain gauge 282 in the detector 28, and control the plunger pump 27 to start. The corresponding valve assembly 223 opens, sucking in concrete from other layers through the first channel 221 and discharging concrete with higher moisture content to a lower moisture content position through the second channel 222. Because the rotating shaft 22 is constantly rotating, when the concrete with higher moisture content is discharged from the outlet of the second channel 222, it will be discharged in a spiral, so that the concrete with lower moisture content and the concrete with higher moisture content are mixed evenly, improving the mixing efficiency.

[0050] like Figure 5 , Figure 7 As shown, the stirring blade 23 includes a first blade 231, a second blade 232, and a third blade 233. The valve assembly 223 includes solenoid valves a2231, b2232, c2233, d2234, e2235, and f2236. Solenoid valves a2231, b2232, and c2233 are located in the first channel 221, while solenoid valves d2234, e2235, and f2236 are located in the second channel.

[0051] There is a linkage between the mixing blade 23 and the valve assembly 223. For example, when the second blade 232 stops rotating due to the resistance of the concrete, the detector 28 detects a signal and transmits it to the controller 5. The controller 5 controls the solenoid valves a2231, c2233, and e2235 to open, while the other valve assemblies 223 close. The plunger pump 27 starts to draw concrete from the solenoid valves a2231 and c2233 and discharge it from the solenoid valve e2235. This process can be repeated to adjust the viscosity of different layers of concrete, so that the overall viscosity of the concrete remains uniform.

[0052] The working principle of this invention is as follows: First, cement and yellow sand are pre-mixed in the pre-mixing silo 1. The drive motor 12 is started, driving the mixing shaft 13 to rotate, which in turn drives the rotating blades fixed on the mixing shaft 13. The rotating blades 13 rotate and mix the cement and yellow sand. After the pre-mixing is completed, the material gate mechanism 15 opens, and the mixed cement and yellow sand fall into the mixing silo 2 for the next mixing step. The water supply mechanism 4 and the feed pipe 26 cooperate. By changing the length of the moving rod 262 inserted into the water supply pipe 43, the water pressure can be automatically adjusted to fully mix the water and the stones. Then, the drive motor 21 is started. The rotating shaft 22 is driven to rotate, which in turn drives the mixing blade 23, which is fixed to the rotating shaft 22, to rotate. The rotating blade 23 mixes the pre-mixed cement, sand, gravel, and water together to form concrete. The scraper 24 is in contact with the tank 25 and rotates under the drive of the rotating shaft 22. It can scrape off the concrete adhering to the tank 25 and automatically clean the concrete adhering to the tank. Finally, the viscosity of the concrete in different layers is detected by the detector 28, and the thin concrete is transferred to the viscous concrete by the plunger pump 27, so that the overall concrete maintains a uniform viscosity.
