Description

Technical Field

[0001] This utility model relates to the field of concrete preparation, and in particular to a rice husk ash quantitative feeding device for preparing rice husk ash concrete. Background Technology

[0002] my country is the world's largest rice producer, generating over 40 million tons of rice husks annually. Aside from a very small portion used for fuel, animal feed, brewing filler, and field fertilizer, most of the rice husks in my country are disposed of as agricultural waste or burned in the wild, causing significant harm to road safety and environmental quality. Meanwhile, with my country's modernization, the demand for high-strength concrete is increasing. Currently, concrete made using rice husk ash as one of the raw materials fully leverages the advantages of readily available raw materials, simple processing, and low cost of general-purpose cement concrete. Furthermore, it is of great significance for addressing issues such as how to more effectively utilize rice husks, reduce environmental impact, and promote comprehensive waste utilization.

[0003] Currently, when preparing rice husk ash concrete, rice husk ash needs to be added to the concrete as an additive for mixing. When feeding the concrete additive, the weighing method is generally used to quantitatively feed the concrete additive. In operation, the concrete additive needs to be added to the weighing hopper for weighing before being transported to the concrete mixing equipment. The process is very cumbersome, resulting in low feeding efficiency.

[0004] Therefore, we propose a rice husk ash quantitative feeding device for the preparation of rice husk ash concrete. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a rice husk ash quantitative feeding device for the preparation of rice husk ash concrete, which solves the problem that the existing quantitative feeding method is very cumbersome and results in low feeding efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rice husk ash quantitative feeding device for preparing rice husk ash concrete, comprising: a feeding hopper and a quantitative feeding component. The bottom of the feeding hopper is fixedly connected to a discharge pipe. The quantitative feeding component is disposed inside the discharge pipe. The quantitative feeding component includes a guide hopper fixedly installed inside the discharge pipe, a feeding wheel rotatably installed inside the guide hopper, and a first driving component for driving the feeding wheel to rotate. Two symmetrically distributed material troughs are opened on the outer circumference of the feeding wheel. Guide ports adapted to the material troughs are opened on both the upper and lower sides of the guide hopper. An adjustment mechanism for adjusting the volume of the material troughs is provided inside the feeding wheel.

[0007] Preferably, the first driving component includes a cylinder fixedly mounted on the outer wall of the discharge pipe, a toothed plate fixedly connected to the piston end of the cylinder, a gear meshing with one side of the toothed plate, and a rotating shaft coaxially connected between the gear and the feeding wheel.

[0008] Preferably, a vibrator is installed on the outer wall of the feeding hopper.

[0009] Preferably, the adjusting mechanism includes an adjusting plate slidably installed in the material trough, a cavity is provided at the center of the feeding wheel, a bidirectional screw is rotatably installed in the cavity, two symmetrical connecting plates are threaded onto the bidirectional screw, a connecting rod is fixedly connected between the connecting plates and the adjusting plate, and a second driving component is connected to the bidirectional screw.

[0010] Preferably, a shaft tube is fixedly connected to the center of the side of the feeding wheel away from the first driving member, and the shaft tube rotates through to the outer wall of the discharge pipe.

[0011] Preferably, the second driving component includes a motor fixedly mounted on the end of the shaft tube, a worm fixedly connected to the output end of the motor, and a worm wheel meshing with one side of the worm, wherein the worm wheel is fixedly connected to the middle of the bidirectional screw.

[0012] Preferably, a limiting rod is fixedly connected inside the cavity, and the connecting plate is slidably sleeved on the limiting rod.

[0013] Preferably, a rubber sealing strip is fixedly connected to the edge of the adjusting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model include:

[0015] By setting up a quantitative feeding component, during feeding, the first drive unit can be activated to drive the feeding wheel to rotate repeatedly. When one of the material receiving troughs of the feeding wheel rotates to align with the upper guide port of the guide hopper, the rice husk ash in the feeding hopper will fall into the material receiving trough along the guide port. When the material receiving trough rotates to align with the lower guide port of the guide hopper, the rice husk ash in the material receiving trough will fall along the guide port and be discharged from the discharge pipe, thus realizing quantitative feeding of rice husk ash, simplifying the feeding process, and improving feeding efficiency.

[0016] By setting an adjustment mechanism to adjust the volume of the material tank, the feeding amount can be controlled. In specific operation, the second drive component can be activated to drive the bidirectional screw to rotate, so that the bidirectional screw drives the two connecting plates to slide relative to or opposite to each other along the limit rod. The connecting plates drive the adjustment plate to slide in the material tank through the connecting rod, thereby adjusting the actual volume of the material tank and controlling the feeding amount to meet different feeding requirements.

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] According to the embodiments of this utility model, combined with Figure 1-5As shown. A rice husk ash quantitative feeding device for preparing rice husk ash concrete includes: a feeding hopper 1 and a quantitative feeding component 2. The rice husk ash is stored in the feeding hopper 1. A discharge pipe 11 is fixedly connected to the bottom of the feeding hopper 1. The quantitative feeding component 2 is disposed in the discharge pipe 11. The quantitative feeding component 2 includes a guide hopper 21 fixedly installed in the discharge pipe 11, a feeding wheel 22 rotatably installed in the guide hopper 21, and a first driving member 23 for driving the feeding wheel 22 to rotate. Two symmetrically distributed material receiving grooves 24 are opened on the outer circumference of the feeding wheel 22. The guide hopper 21 has corresponding material receiving grooves on both its upper and lower sides. The 24-phase compatible feed inlet 25, through the setting of the quantitative feeding component 2, can activate the first drive component 23 to drive the feeding wheel 22 to rotate repeatedly during feeding. When one of the receiving troughs 24 of the feeding wheel 22 rotates to align with the upper feed inlet 25 of the feed hopper 21, the rice husk ash in the feeding hopper 1 will fall into the receiving trough 24 along the feed inlet 25. When the receiving trough 24 rotates to align with the lower feed inlet 25 of the feed hopper 21, the rice husk ash in the receiving trough 24 will fall along the feed inlet 25 and be discharged from the discharge pipe 11, realizing the quantitative feeding of rice husk ash, simplifying the feeding process and improving feeding efficiency.

[0028] Specifically, the first driving component 23 includes a cylinder 231 fixedly installed on the outer wall of the discharge pipe 11, a toothed plate 232 fixedly connected to the piston end of the cylinder 231, a gear 233 meshing with one side of the toothed plate 232, and a rotating shaft 234 coaxially connected between the gear 233 and the feeding wheel 22. The toothed plate 232 is arranged vertically, and the toothed plate 232 and the outer wall of the discharge pipe 11 are connected by a sliding rail. By setting the first driving component 23, when feeding, the cylinder 231 can be activated to drive the toothed plate 232 to slide up and down, so that the toothed plate 232 drives the gear 233 to rotate repeatedly, and the gear 233 drives the feeding wheel 22 to rotate repeatedly through the rotating shaft 234.

[0029] Furthermore, a vibrator 12 is installed on the outer wall of the feeding hopper 1. By setting the vibrator 12, the vibrator 12 can be activated to drive the feeding hopper 1 to shake during feeding, which helps the rice husk ash in the feeding hopper 1 to fall downward and reduces the occurrence of material blockage.

[0030] Furthermore, the feeding wheel 22 is internally equipped with an adjustment mechanism 26 for adjusting the volume of the material trough 24. The adjustment mechanism 26 includes an adjustment plate 261 slidably installed in the material trough 24. A cavity is formed at the center of the feeding wheel 22, and a bidirectional screw 262 is rotatably installed in the cavity. Two symmetrical connecting plates 263 are threaded onto the bidirectional screw 262. A connecting rod 264 is fixedly connected between the connecting plates 263 and the adjustment plate 261. A second driving member 265 is connected to the bidirectional screw 262. A shaft tube 266 is fixedly connected at the center of the side of the feeding wheel 22 away from the first driving member 23. The shaft tube 266 rotatably passes through to the discharge point. A limiting rod 267 is fixedly connected to the outer wall of the tube 11 and inside the cavity. The connecting plate 263 is slidably sleeved on the limiting rod 267. By setting an adjusting mechanism 26 to adjust the volume of the material trough 24, the feeding amount can be controlled. In specific operation, the second driving component 265 can be activated to drive the bidirectional screw 262 to rotate, so that the bidirectional screw 262 drives the two connecting plates 263 to slide relative to or opposite to each other along the limiting rod 267. The connecting plate 263 drives the adjusting plate 261 to slide in the material trough 24 through the connecting rod 264, so that the actual volume of the material trough 24 can be adjusted, thereby controlling the feeding amount and meeting different feeding requirements.

[0031] Specifically, the second driving component 265 includes a motor 2651 fixedly installed at the end of the shaft tube 266, a worm 2652 fixedly connected to the output end of the motor 2651, and a worm wheel 2653 meshing with one side of the worm 2652. The worm wheel 2653 is fixedly connected to the middle of the bidirectional screw 262. By setting the second driving component 265, during adjustment, the motor 2651 can be started to drive the worm 2652 to rotate, which in turn drives the worm wheel 2653 to rotate, and the worm wheel 2653 drives the bidirectional screw 262 to rotate.

[0032] Furthermore, a rubber sealing strip 268 is fixedly connected to the edge of the adjusting plate 261. By setting the rubber sealing strip 268, the sealing performance between the adjusting plate 261 and the inner wall of the material container 24 can be improved.

[0033] In practical use, the working principle of this utility model is as follows:

[0034] First, adjust the actual volume of the material trough 24 according to the amount of rice husk ash fed. In specific operation, the motor 2651 can be started to drive the worm gear 2652 to rotate, which in turn drives the worm wheel 2653 to rotate. The worm wheel 2653 drives the bidirectional screw 262 to rotate, which in turn drives the two connecting plates 263 to slide relative to or opposite to each other along the limiting rod 267. This allows the connecting plates 263 to drive the adjusting plate 261 to slide within the material trough 24 via the connecting rod 264, thereby adjusting the actual volume of the material trough 24 to a suitable level.

[0035] Then, during feeding, the cylinder 231 can be activated to drive the toothed plate 232 to slide up and down, causing the toothed plate 232 to drive the gear 233 to rotate repeatedly. The gear 233 drives the feeding wheel 22 to rotate repeatedly through the rotating shaft 234. When one of the material troughs 24 of the feeding wheel 22 rotates to align with the upper guide port 25 of the guide hopper 21, the rice husk ash in the feeding hopper 1 will fall into the material trough 24 along the guide port 25. When the material trough 24 rotates to align with the lower guide port 25 of the guide hopper 21, the rice husk ash in the material trough 24 will fall along the guide port 25 and be discharged from the discharge pipe 11, thus realizing the quantitative feeding of rice husk ash.

[0036] In summary, the rice husk ash quantitative feeding equipment for preparing rice husk ash concrete can achieve quantitative feeding of rice husk ash by setting up the quantitative feeding component 2, which simplifies the feeding process and improves the feeding efficiency.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
