Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a concrete feeding device. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials; usually, the term concrete refers to concrete using cement as cementing material and sand and stone as aggregates.

[0003] To ensure the needs of construction, there are certain requirements for the discharge speed of the hopper. Existing concrete hoppers have some drawbacks. Most existing hoppers are set at a fixed angle. Because concrete is easy to solidify, the discharge speed is slow in some cases, which makes it difficult to discharge the concrete. It may accumulate on the hopper, causing blockages and uneven discharge, which reduces work efficiency.

[0004] On the other hand, existing concrete feeding devices generally only include one feeding hopper. After the concrete is mixed, it is fed through the feeding hopper. However, the size of the aggregates used in civil concrete production is usually different, and the difference is quite large. The size of the aggregates determines some characteristics of the concrete. Relatively large aggregates have higher strength, while relatively small aggregates have better adhesion. Therefore, concrete with different aggregate sizes is suitable for different construction scenarios. Sometimes it is necessary to use a mixture of large and small aggregates, and sometimes it is necessary to use large and small aggregates separately. However, most traditional feeding devices do not have the function of screening concrete, so their use is somewhat limited.

[0005] Based on this, a concrete feeding device is proposed, providing a new solution to the aforementioned technical problems. Utility Model Content

[0006] Therefore, it is necessary to provide a concrete feeding device to address the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The concrete feeding device specifically includes a storage tank and a feeding hopper disposed below the storage tank. A connecting mechanism is provided between the storage tank and the feeding hopper, and the storage tank and the feeding hopper are connected through the connecting mechanism. A vibrating feeding component is provided inside the feeding hopper, and an auxiliary feeding component and a cleaning component are provided on the vibrating feeding component.

[0009] Preferably, the vibratory feeding assembly includes a feeding plate, with several connecting springs connected to both sides of the feeding plate. The ends of the connecting springs away from the feeding plate are connected to the feeding hopper. Vibrators are symmetrically installed in the middle of the bottom sides of the feeding plate. A protective cover is fixedly connected to the bottom of the feeding plate and outside the vibrators. The bottom of the protective cover is provided with heat dissipation holes. A second feeding port is provided at the bottom of the feeding hopper and at the end of the feeding plate.

[0010] Preferably, side baffles are provided on both sides inside the hopper and above the feeding plate, the side baffles are fixedly connected to the hopper, and a vibration gap is provided between the side baffles and the feeding plate.

[0011] Preferably, the bottom of the feeding plate and the feeding hopper are provided with a screening flow chamber, the feeding plate is provided with a plurality of feeding holes, the bottom of the feeding hopper and located below the end of the feeding plate is provided with a first feeding port, and baffles are provided on both sides of the top of the first feeding port. The baffles are fixedly connected to the feeding hopper, and the first feeding port and the baffles separate the screening flow chamber from the second feeding port.

[0012] Preferably, the auxiliary feeding assembly includes a plurality of stirring rollers, which are rotatably connected to the inside of the feeding hopper and located above the feeding plate. The stirring rollers pass through the side baffle and are rotatably connected to it. A drive pulley is fixed to the outer side of one end of each stirring roller, and a drive belt is connected to the outer side of each drive pulley.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model, through the structural design of the connecting mechanism, allows for adjustment of the tilt angle of the hopper during use, thereby controlling the concrete discharge speed and adapting to different work requirements, thus improving adaptability.

[0015] This invention improves the efficiency of concrete feeding by using a vibrating feeding assembly.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present 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 should fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-8 This utility model provides a concrete feeding device, including a storage tank 1 and a feeding hopper 4 disposed below the storage tank 1. A connecting mechanism is provided between the storage tank 1 and the feeding hopper 4, and the storage tank 1 and the feeding hopper 4 are connected by the connecting mechanism. A vibrating feeding component is provided inside the feeding hopper 4, and an auxiliary feeding component and a cleaning component are provided on the vibrating feeding component. Specifically, through the structural design of the vibrating feeding component, the concrete feeding efficiency can be improved. At the same time, the vibration of the feeding plate 6 slows down the concrete setting speed and makes the feeding more uniform. It also makes it less likely for the concrete to stick to the feeding plate 6, thus preventing the concrete from accumulating on the feeding plate 6, improving practicality and ease of use. Through the structural design of the auxiliary feeding mechanism, the concrete feeding is further assisted, which can effectively prevent the concrete from accumulating on the feeding plate 6 and facilitate better screening. Through the setting of the cleaning component, the inside of the feeding hopper 4 can be cleaned after the feeding is completed for the next use.

[0024] Please refer to Figure 1 The connecting mechanism includes a first connecting rod 2 and a hydraulic cylinder 3. The first connecting rod 2 is fixedly connected to both sides of the bottom of the storage tank 1. The hopper 4 is rotatably connected between the bottom of the first connecting rod 2 on both sides. The hydraulic cylinder 3 is rotatably connected to both sides of the storage tank 1 and the hopper 4. Specifically, the first connecting rod 2 is set vertically, and the hydraulic cylinder 3 is set at an angle. When it is necessary to adjust the angle of the hopper 4, the hydraulic cylinder 3 is activated, and its inner piston rod extends or retracts, thereby driving the hopper 4 to rotate around its connection with the first connecting rod 2, thereby adjusting the angle of the hopper 4.

[0025] Please refer to Figure 2-5The vibratory feeding assembly includes a feeding plate 6, with several connecting springs 5 ​​connected to both sides of the feeding plate 6. The ends of the connecting springs 5 ​​furthest from the feeding plate 6 are connected to the feeding hopper 4. Vibrators 7 are symmetrically installed at the center of both sides of the bottom of the feeding plate 6. A protective cover 8 is fixedly connected to the bottom of the feeding plate 6, outside the vibrators 7. The bottom of the protective cover 8 has heat dissipation holes. A second feeding port 19 is provided at the bottom of the feeding hopper 4, at the end of the feeding plate 6. Specifically, in this embodiment, the feeding plate 6 is a straight plate without holes, and the feeding plate 6 is arranged parallel to the feeding hopper 4. The feeding plate 6 is connected to the feeding hopper 4 via connecting springs 5. To improve the feeding efficiency... The load-bearing capacity of the material plate 6 can increase the number of connecting springs 5. In order to balance the tension of the connecting springs 5 ​​on the material plate 6 on both sides, multiple connecting springs 5 ​​can be symmetrically arranged on both sides of the material plate 6. When concrete falls from the storage tank 1 onto the material plate 6, it will flow along the material plate 6. When the concrete is flowing, the vibrator 7 is activated, which can drive the material plate 6 to vibrate. The vibration of the material plate 6 makes the material flow more uniform and efficient. The vibrator 7 is protected by the protective cover 8. The design of the heat dissipation hole can prevent the vibrator 7 from overheating during operation.

[0026] Please refer to Figure 5 Side baffles 9 are provided on both sides inside the hopper 4 and above the discharge plate 6. The side baffles 9 are fixedly connected to the hopper 4. A vibration gap is provided between the side baffles 9 and the discharge plate 6. Specifically, the side baffles 9 can prevent concrete from falling from the side of the discharge plate 6 and affecting the use of the connecting spring 5. At the same time, the vibration gap design provides movement space for the vibration of the discharge plate 6 and prevents the discharge plate 6 from interfering with the side baffles 9 when it vibrates.

[0027] Please refer to Figure 6-8 The bottom of the feeding plate 6 and the feeding hopper 4 are provided with a screening flow chamber. The feeding plate 6 has several feeding holes. The bottom of the feeding hopper 4 and below the end of the feeding plate 6 is provided with a first feeding port 18. The top two sides of the first feeding port 18 are provided with baffles, which are fixedly connected to the feeding hopper 4. The first feeding port 18 and the baffles separate the screening flow chamber from the second feeding port 19. Specifically, in this embodiment, the feeding plate 6 can be used as a screening plate through the design of the feeding holes. When concrete falls from the storage tank 1 onto the feeding plate 6, it will flow along the feeding plate 6. Some of the concrete containing small-diameter stones will fall into the screening flow chamber through the feeding holes. The concrete in the screening flow chamber will be discharged through the first feeding port 18. The baffles provide good guidance for the discharge of concrete in the screening flow chamber. Some of the concrete containing large-diameter stones will directly enter the second feeding port 19 through the feeding plate 6 for discharge.

[0028] Please refer to Figure 4The auxiliary feeding assembly includes several stirring rollers 10, which are rotatably connected to the inside of the feeding hopper 4 and located above the feeding plate 6. The stirring rollers 10 pass through and are rotatably connected to the side baffle 9. A drive pulley 11 is fixed to the outer side of one end of each stirring roller 10, and a drive belt 12 is connected to the outer side of each drive pulley 11. A mounting bracket 13 is fixed to the outer side of the feeding hopper 4, near the drive belt 12. A drive motor 14 is mounted on the end of the mounting bracket 13 away from the feeding hopper 4, and drive teeth are fixed to the output end of the drive motor 14. The drive gear 15 is meshed with a transmission gear 16 on one side. The transmission gear 16 is fixedly connected to one of the mixing rollers 10. Specifically, the mixing rollers 10 are arranged horizontally. In order to prevent concrete from accumulating, the number of mixing rollers 10 can be increased. When the mixing rollers 10 need to be operated to mix concrete, the drive motor 14 starts, and the drive gear 15 on its output end drives the transmission gear 16 to rotate, which in turn drives the mixing rollers 10 connected to it to rotate. Then, through the transmission pulley 11 and the transmission belt 12, multiple mixing rollers 10 are driven to rotate simultaneously.

[0029] Please refer to Figure 7 The cleaning assembly includes water inlet pipes 17 located on both sides inside the hopper 4. The water inlet pipes 17 are positioned between the side baffle 9 on the same side and the side wall of the hopper 4. Several high-pressure nozzles 20 are installed on the water inlet pipes 17, and the high-pressure nozzles 20 penetrate the side baffle 9. Specifically, after the concrete is discharged, water is injected into the water inlet pipes 17, and cleaning is completed simultaneously through the high-pressure nozzles 20 installed on the water inlet pipes 17. To improve the cleaning effect, the number of high-pressure nozzles 20 can be increased to make the cleaning equipment more effective.

[0030] The specific working principle of the concrete feeding device provided by this utility model is as follows: When using this feeding equipment, after the concrete is produced through the storage tank 1, it falls onto the feeding plate 6 inside the feeding hopper 4 and is fed through the feeding plate 6. When it is necessary to adjust the tilt angle of the hopper 4 to control the feeding speed, the hydraulic cylinder 3 is activated, and the piston rod on its inner side extends or retracts, thereby driving the hopper 4 to rotate around its connection with the first connecting rod 2, thereby adjusting the tilt angle of the hopper 4. When it is necessary to speed up the concrete feeding, the vibrator 7 is activated, which can drive the feeding plate 6 to vibrate. The vibration of the feeding plate 6 makes the feeding more uniform and efficient. When concrete with different aggregate sizes is required, the discharge plate 6 can be used as a screening plate due to the design of the discharge hole. When concrete falls from the storage tank 1 onto the discharge plate 6, it will flow along the discharge plate 6. Some of the concrete containing smaller aggregates will fall into the screening flow chamber through the discharge hole. The concrete in the screening flow chamber will be discharged through the first discharge port 18. The baffle provides good guidance for the discharge of concrete in the screening flow chamber. Some of the concrete containing larger aggregates will directly enter the second discharge port 19 through the discharge plate 6 for discharge. When the mixing roller 10 needs to be operated to mix concrete, the drive motor 14 starts, and the drive gear 15 on its output end drives the transmission gear 16 to rotate, which in turn drives the mixing roller 10 connected to it to rotate, and then drives multiple mixing rollers 10 to rotate simultaneously through the transmission pulley 11 and the transmission belt 12. After the concrete is poured, water is injected into the water inlet pipe 17, and cleaning is completed through the high-pressure nozzle 20 installed on the water inlet pipe 17.
