Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to a concrete production raw material conveying device. Background Technology

[0002] In concrete production, raw material transportation is a crucial process connecting various production stages. Currently, the industry widely uses conveyor systems to transfer raw materials such as sand, gravel, and cement. These systems typically consist of a conveyor body, supporting structures, and drive components, enabling the transport of raw materials from storage areas to the next workstation, such as mixing. Some conveyor systems are also equipped with auxiliary structures to adapt to the raw material transportation needs of different production scenarios, providing a fundamental guarantee for the continuity and efficiency of concrete production. They are an indispensable key piece of equipment in concrete production lines.

[0003] Chinese Patent Announcement No. CN220885863U discloses a concrete production raw material conveying device, including a conveying device and an mounting plate. A support assembly is provided under the mounting plate. Two mounting plates are connected to the conveying device, and a driving device matching the conveying device is provided on the side wall of one of the mounting plates. Baffles are provided on the mounting plates, and a flipping mechanism is provided between the two baffles. A cleaning mechanism is provided at the bottom of the mounting plates via an adjustment mechanism. This invention allows for the slow flipping of raw materials before conveying them to the next station. This prevents clumping, facilitates subsequent processing and mixing, and ensures the quality of subsequent concrete processing. It also prevents materials from adhering to the conveying device, avoiding waste, and ensures the cleanliness of the conveying device surface for easy cleaning and subsequent conveying.

[0004] In the existing technology, there is no temperature regulation design in the use of a concrete production raw material conveying device. When the ambient temperature is low, the raw materials are prone to moisture absorption and clumping due to the low temperature, which will affect the quality stability of subsequent concrete processing. Therefore, we make improvements to this and propose a concrete production raw material conveying device. Utility Model Content

[0034] Example 1: Please refer to the appendix of the instruction manual. Figure 1-4A concrete production raw material conveying device includes a conveying device body 1, a conveying structure 22 on the conveying device body 1, a protective cover 2 fixedly installed on the top of the conveying device body 1, a recycling box 3 movably connected to the bottom of the conveying device body 1, an L-shaped base pipe 4 fixedly installed on one side of the conveying device body 1, a connecting pipe 5 and an F-shaped auxiliary pipe 6 fixedly installed on one side of the L-shaped base pipe 4 and on the side of both the conveying device body 1 and the protective cover 2, respectively, and both the connecting pipe 5 and the F-shaped auxiliary pipe 6 are connected to the L-shaped base pipe 4. The connecting pipe 5 is located above the recycling box 3 and is fixedly connected to the conveying device body 1. The F-shaped auxiliary pipe 6... The tube 6 is inserted into the interior of the protective cover 2 and fixedly connected thereto. Several output tubes are fixedly installed on one side of the connecting tube 5 and the F-type auxiliary tube 6. Through holes that cooperate with the output tubes are opened on the connecting tube 5 and the F-type auxiliary tube 6. A heating cavity 8 is opened on the protective cover 2. Two mounting plates are fixedly installed on the inner walls of the two sides of the protective cover 2 that are close to each other and located inside the heating cavity 8. Heating rods 10 are fixedly installed on the side of the two mounting plates that are far from each other. The ends of several heating rods 10 that are far from the mounting plates are fixedly connected to the protective cover 2. Several air outlet tubes 11 are embedded in the bottom of the protective cover 2. Several air outlet tubes 11 are connected to the heating cavity 8.

[0035] The outer side of the L-shaped base pipe 4 is fixedly installed with a flange to facilitate the connection of an external water tank for water supply.

[0036] In this embodiment of the utility model, the transmission structure 22 is the core component for material transportation, responsible for moving the concrete material. The protective cover 2 covers the top of the conveying device body 1, surrounding the material transportation area to form a relatively closed space and preventing the material from spilling outwards during transportation.

[0037] The recycling bin 3 is located below the conveying device body 1. When raw materials fall from the conveying structure 22, they will fall directly into the recycling bin 3 to collect the spilled raw materials. The L-shaped base pipe 4 serves as the main pipe and is connected to the bottom of the conveying device body 1 and the inside of the protective cover 2 through the connecting pipe 5 and the F-shaped auxiliary pipe 6, respectively, to form a liquid conveying path. The output pipe is the outlet of these fluids, and the through hole ensures that the fluid can smoothly enter the output pipe from the connecting pipe 5 and the F-shaped auxiliary pipe 6.

[0038] Heating rod 10 is installed inside heating chamber 8 of protective cover 2. After being powered on, it generates heat to heat the air inside heating chamber 8. The heated air enters the interior of protective cover 2 through air outlet pipe 11 at the bottom of protective cover 2 to heat and keep the raw materials being transported, and reduce humidity. The flange on the outside of L-shaped base pipe 4 can be connected to the pipe of external water tank. When water washing is required, the corresponding valve is opened, and water can be transported to the parts of the device that need to be cleaned through L-shaped base pipe 4, connecting pipe 5, F-shaped auxiliary pipe 6 and output pipe.

[0039] In this embodiment of the utility model, the transmission structure 22 provides power for the raw material conveying, ensuring that the raw material can move along a predetermined path. The protective cover 2 effectively blocks the spillage of raw materials, reduces dust generation, improves the production environment, and protects the health of operators. The recycling box 3 recovers the spilled raw materials, avoiding waste and reducing production costs. The fluid conveying passage composed of the L-shaped base pipe 4, connecting pipe 5, and F-shaped auxiliary pipe 6 is cleaned by water flowing into an external water tank. The cooperation of the heating rod 10, heating cavity 8, and air outlet pipe 11 can heat and dehumidify the inside of the protective cover 2, preventing raw materials from adhering to the transmission structure 22 and the inner wall of the protective cover 2 in a humid environment, thus ensuring smooth conveying.

[0040] Example 2: Please refer to the appendix of the instruction manual. Figure 1-6 In a preferred embodiment of this utility model, threaded nozzles 7 are threadedly connected to the outer sides of several output pipes, a pump 9 is embedded on one side of the protective cover 2, the output pipe of the pump 9 is connected to the heating chamber 8, a dustproof net is fixedly installed inside the input pipe of the pump 9, a first control valve is fixedly installed inside the recycling box 3 and on the F-type auxiliary pipe 6, and a second control valve is fixedly installed on the L-type base pipe 4.

[0041] The transmission structure 22 consists of a U-shaped plate, a transmission belt, a driven roller, a third servo motor, a synchronous belt, two transmission rollers, and two synchronous pulleys. The driven roller and the two transmission rollers are connected to the transmission belt. The two transmission rollers are fixedly connected to the two synchronous pulleys. Both transmission rollers are inserted into the body of the conveying device 1 and rotated therewith. The third servo motor is fixedly connected to the body of the conveying device 1, and the output end of the servo motor is fixedly connected to one of the synchronous pulleys. The driven roller is inserted into the body of the U-shaped plate and rotated therewith. Two electric telescopic rods are fixedly installed inside the body of the conveying device 1 at the bottom of the U-shaped plate. The output ends of the two electric telescopic rods are fixedly connected to the U-shaped plate. The U-shaped plate is slidably connected to the body of the conveying device 1. Two pressure sensors are embedded on one side of the body of the conveying device 1, on the side of the transmission belt.

[0042] The top of the conveyor belt is provided with two side plates 23. Triangular brackets are fixedly installed on the side of the two side plates 23 that are far apart from each other, and several triangular brackets are fixedly connected to the conveyor body 1. Rubber pads are embedded at the bottom of the two side plates 23.

[0043] The recycling bin 3 is equipped with a magnetic grid 12 inside. The magnetic grid 12 passes through the top of the recycling bin 3 and is slidably connected to it. Several fixing bolts are provided on both sides of the top of the magnetic grid 12. Several fixing bolts are inserted into the inside of the recycling bin 3 and are threadedly connected to it. Several fixing bolts pass through the magnetic grid 12 and are threadedly connected to it.

[0044] A frame 13 is fixedly installed on the top of the recycling bin 3. The frame 13 consists of two support rods. A cleaning roller 14 is set above the recycling bin 3. A ring-shaped neodymium iron boron magnet is fixedly installed on the outside of the cleaning roller 14. A first servo motor 15 is fixedly installed on one side of one of the support rods. The output end of the first servo motor 15 is fixedly connected to the cleaning roller 14. The other support rod is inserted into the interior of the cleaning roller 14 and rotatedly connected to it. Several elastic rubber pads are fixedly installed on the outside of the cleaning roller 14.

[0045] A number of T-shaped rods 16 are fixedly installed on one side of the conveying device body 1. The T-shaped rods 16 are inserted into the inside of the recycling box 3 and slidably connected thereto. A push plate 20 is provided on the side of the recycling box 3 away from the T-shaped rods 16. The push plate 20 is inserted into the inside of the conveying device body 1 and the recycling box 3 and slidably connected thereto. A second servo motor 17 is fixedly installed inside the conveying device body 1. A threaded rod 18 is fixedly installed at the output end of the second servo motor 17. The threaded rod 18 is rotatably connected to the conveying device body 1. A T-shaped rotating drum 19 is threadedly connected to the outside of the threaded rod 18. The T-shaped rotating drum 19 is slidably connected to the conveying device body 1 and is fixedly connected to the push plate 20. The T-shaped rotating drum 19 is composed of a cylinder and a square ring.

[0046] A controller 24 is embedded on one side of the conveyor body 1. The controller 24 is electrically connected to the first servo motor 15, the second servo motor 17, the first control valve, the second control valve, the third servo motor, two pressure sensors and an electric telescopic rod. A feeding plate 21 is fixedly installed on one side of the conveyor body 1 and is slidably connected to the conveyor belt. Two rubber rings are embedded on the side of the feeding plate 21 near the conveyor structure 22.

[0047] In this embodiment of the invention, the threaded nozzle 7 is threadedly connected to the output pipe. By rotating it, the angle and direction of the nozzle can be changed, thereby adjusting the spray angle and range of the water flow, enabling it to act more precisely on the parts that need cleaning or auxiliary conveying, while also facilitating the disassembly and replacement of the threaded nozzle 7. When the pump 9 is working, it draws in outside air, pressurizes it, and then delivers it to the heating chamber 8 through the output pipe, providing an air source for the heating chamber 8 and accelerating the circulation of hot air. The dustproof screen inside the pump 9 input pipe can filter dust and impurities in the air, preventing them from entering the pump 9 and causing damage, and also preventing impurities from entering the device and contaminating the raw materials. The first control valve is installed on the F-type auxiliary pipe 6, and controls the flow of fluid in the F-type auxiliary pipe 6 by opening or closing it. The second control valve is installed on the L-type base pipe 4, and controls the flow of fluid in the entire L-type base pipe 4. By operating the two control valves, the fluid delivery path and flow rate can be flexibly controlled.

[0048] After the third servo motor starts, its output drives the synchronous pulley connected to it to rotate. Through the transmission action of the synchronous belt, it drives another synchronous pulley to rotate, thereby causing the two transmission rollers to rotate synchronously. The transmission rollers drive the transmission belt to move. The raw materials are placed on the transmission belt and move together with the transmission belt to realize the conveying of raw materials. The driven roller is installed on the U-shaped plate and can be extended and retracted by an electric telescopic rod, which drives the U-shaped plate to move up and down. The U-shaped plate drives the driven roller to move up and down, thereby adjusting the tension of the transmission belt. When the transmission belt is loose, the electric telescopic rod extends, causing the driven roller to move downward and tighten the transmission belt. When the transmission belt is too tight, the electric telescopic rod shortens, causing the driven roller to move upward and loosen the transmission belt. The pressure sensor is installed on one side of the transmission belt, which can sense the pressure change of the raw materials on the transmission belt and convert the pressure signal into an electrical signal and transmit it to the controller 24, providing a basis for the controller 24 to adjust the operating status of the transmission belt.

[0049] Two side plates 23 are located on both sides of the conveyor belt, extending upwards from the edge of the conveyor belt to form a barrier. When the raw material is conveyed on the conveyor belt, it can prevent the raw material from moving to the sides of the conveyor belt and prevent the raw material from spilling from the edge of the conveyor belt. One end of the triangular bracket is fixedly connected to the side plate 23, and the other end is fixedly connected to the conveyor body 1. Utilizing the stability of the triangle, it provides a firm support for the side plate 23, ensuring that the side plate 23 will not shake or deform during the impact of the raw material and the operation of the device. The rubber pad at the bottom of the side plate 23 is in contact with the surface of the conveyor belt. The rubber pad has a certain elasticity and friction, which can fill the gap between the side plate 23 and the conveyor belt, enhance the effect of preventing the raw material from spilling, and also avoid the bottom of the side plate 23 directly rigidly contacting the conveyor belt and thus avoiding wear on the conveyor belt.

[0050] In this embodiment of the invention, the magnetic grid 12 is made of a strongly magnetic material and is installed inside the recycling bin 3. When the recycling bin 3 collects spilled raw materials, the raw materials pass through the magnetic grid 12. Magnetic impurities such as iron filings contained in the raw materials are adsorbed by the magnetic grid 12, thus separating them from other raw materials. The magnetic grid 12 is slidably connected to the recycling bin 3. When it is necessary to clean the magnetic impurities adsorbed on the magnetic grid 12, the fixing bolts are unscrewed, and the magnetic grid 12 can be pulled out of the recycling bin 3. After cleaning, the magnetic grid 12 is inserted back into the recycling bin 3, and the fixing bolts are tightened to fix the magnetic grid 12 inside the recycling bin 3, allowing it to continue to adsorb impurities.

[0051] The frame 13 fixed to the top of the recycling bin 3 consists of two support rods, which provide support for the cleaning roller 14. The annular neodymium iron boron magnet on the outside of the cleaning roller 14 can adsorb ferromagnetic impurities that may be present in the raw materials. The first servo motor 15 drives the cleaning roller 14 to rotate and clean the raw materials in the recycling bin 3. Several elastic rubber pads on the outside of the cleaning roller 14 can reduce damage to the raw materials during the cleaning process. The cleaning method of the rotating cleaning roller 14 improves the removal efficiency of impurities in the raw materials. The strong magnetism of the annular neodymium iron boron magnet ensures the effect of impurity adsorption. The setting of elastic rubber pads avoids the raw materials being excessively squeezed or worn during the cleaning process, thus protecting the integrity of the raw materials.

[0052] Several T-shaped rods 16 on one side of the conveying device body 1 are inserted into the recycling box 3 and slidably connected to it, which guides the movement of the recycling box 3. The second servo motor 17 drives the threaded rod 18 to rotate, so that the T-shaped rotating drum 19 connected to the outer thread of the threaded rod 18 slides in the conveying device body 1, thereby driving the push plate 20 to slide in the conveying device body 1 and the recycling box 3, which can push the raw materials in the recycling box 3 to the designated position.

[0053] The controller 24 embedded on one side of the conveyor body 1 is electrically connected to the first servo motor 15, the second servo motor 17, the first control valve, the second control valve, the third servo motor, two pressure sensors, and the electric telescopic rod. It can receive signals from each component and control them to realize the automated operation of the device. The feed plate 21 fixed on one side of the conveyor body 1 is slidably connected to the conveyor belt and is used to guide the raw materials on the conveyor belt to the designated position. Two rubber rings embedded on the side of the feed plate 21 near the conveyor structure 22 reduce the friction between the feed plate 21 and the conveyor belt.

[0054] Example 3: Please refer to the appendix of the instruction manual. Figure 5 Included with instruction manual Figure 6 In a preferred embodiment of this utility model, a fixing block is fixedly installed on one side of the conveying device body 1 and on both sides corresponding to the unloading plate 21. An adjustment structure is provided on each of the two fixing blocks. The adjustment structure includes an adjustment plate, which is slidably connected to the unloading plate 21 via a rotating shaft. The adjustment plate is inserted into the inside of the fixing block and slidably connected to it. A rubber pad is embedded on the side of the adjustment plate near the unloading plate 21. A rubber ring is fixedly installed on the outside of the rotating shaft and on the side of the adjustment plate. A worm gear is fixedly installed at the bottom of the rotating shaft. A worm is meshed on the outside of the worm gear. Both the worm gear and the worm are rotatably connected to the fixing block. A handle is fixedly installed on one side of the worm and passes through one side of the fixing block and is rotatably connected to it.

[0055] In this embodiment of the utility model, the adjustment structure on the fixed blocks on one side of the conveying device body 1, corresponding to the two sides of the feeding plate 21, drives the worm to rotate by rotating the handle. The worm meshes with the worm wheel to rotate the shaft, which in turn drives the adjustment plate to rotate around the shaft. The adjustment plate slides in the fixed block, which can adjust the angle of the feeding plate 21.
