Description

Technical Field

[0001] This utility model relates to the field of concrete processing, and in particular to a grouting device for concrete processing. Background Technology

[0002] Concrete, or simply concrete, is a general term for engineering composite materials that bind aggregates together with cementing materials. The term concrete usually refers to cement concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water, admixtures and additives in a certain proportion. It is widely used in civil engineering. In order to better pour this concrete into different gaps in the building, people use grouting devices to inject the mixed concrete into the corresponding positions through external pipes for filling.

[0003] In practical use, existing grouting devices typically have open storage hoppers, requiring users to determine whether to add concrete grout. Often, grout is added only when there is no concrete left in the device. However, by this time, the device has already transported the tail material mixed with air out, resulting in uneven concrete pouring. Therefore, we propose a concrete grouting device that stops the machine promptly when the concrete in the storage hopper reaches the tail material level, allowing workers to replenish the concrete. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing grouting devices cannot monitor the concrete in the storage hopper, and personnel cannot fill the concrete in a timely manner, which easily leads to uneven concrete pouring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a grouting device for concrete processing, comprising a cylinder, an extrusion plate sliding inside the cylinder, a top cover fixed to the top of the cylinder, a square rod fixed to the top of the extrusion plate, the top end of the square rod sliding through the middle of the top cover, a feed pipe fixed to the middle of the square rod and the extrusion plate, a pressurizing assembly provided on the top cover, a groove provided on the top of the top cover, a proximity light sensor fixed in the groove, and a grouting assembly provided at the bottom of the cylinder.

[0006] Preferably, the pressurization assembly includes an air compressor fixed to the top of the top cover, with an air inlet and an air outlet fixedly connected to the top of the top cover, and a connecting pipe fixedly connected to the top of the air compressor's air outlet and the air inlet.

[0007] Preferably, a first solenoid valve is fixed to the top of the air outlet, and an exhaust pipe is fixed to the other end of the first solenoid valve.

[0008] Preferably, the grouting assembly includes an extrusion pipe, the discharge end of which is fixed with a second solenoid valve, and one end of the second solenoid valve is fixed with a connecting pipe.

[0009] Preferably, a reference plate is fixed to the top of the square rod, and the output end of the proximity sensor is aligned with the reference plate.

[0010] Preferably, the top cover has a sliding opening in the middle, and the square rod is slidably connected in the sliding opening.

[0011] Preferably, the bottom end of the feed pipe passes through the extrusion plate, the top end of the feed pipe passes through the top of the square rod, and a valve is installed at the top end of the feed pipe.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up an extrusion plate, a feeding pipe, a pressurizing component, and a proximity light sensor, the extrusion plate can move downwards accordingly as the concrete inside the cylinder decelerates, so that the controller of the grouting device can calculate the remaining amount of concrete inside the cylinder through the proximity light sensor and a reference plate. This allows for monitoring of the remaining amount, enabling timely shutdown to prompt personnel to add material. As a result, the grouting device will not deliver tail material mixed with a lot of air, making the concrete grouting more uniform. Furthermore, the extrusion plate can clean the inner wall of the cylinder while moving, solving the problem of concrete sticking to the wall inside the grouting device. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a grouting device for concrete processing, including a cylinder 1, an extrusion plate 2 sliding inside the cylinder 1, a top cover 3 fixed to the top of the cylinder 1, a square rod 4 fixed to the top of the extrusion plate 2, the top end of the square rod 4 sliding through the middle of the top cover 3, a feed pipe 5 fixed to the middle of the square rod 4 and the extrusion plate 2, a pressure assembly 6 provided on the top cover 3, a groove 7 opened on the top of the top cover 3, a proximity light sensor 8 fixed in the groove 7, and a grouting assembly 9 provided at the bottom of the cylinder 1.

[0022] The effect achieved by the entire embodiment 1 is that the extrusion plate 2 can move up and down accordingly as the amount of concrete in the cylinder 1 increases or decreases. With the detection of the proximity light sensor 8, the control device can calculate the remaining amount of concrete in the cylinder 1 in real time, realize the monitoring of the remaining amount, so as to stop the machine in time and prompt the personnel to add material, so that the last part of the tail material will not be mixed with a lot of air and transported out.

[0023] Example 2: As Figures 1-4As shown, the pressurization assembly 6 includes an air compressor 601 fixed to the top of the top cover 3. The top of the top cover 3 is fixedly connected to an air inlet 602 and an air outlet 603. The air outlet end of the air compressor 601 is fixedly connected to the top of the air inlet 602 by a connecting pipe 604. The top of the air outlet 603 is fixedly connected to a first solenoid valve 605, and the other end of the first solenoid valve 605 is fixedly connected to an exhaust pipe. The grouting assembly 9 includes an extrusion pipe 901. The discharge end of the extrusion pipe 901 is fixedly connected to a second solenoid valve 902, and one end of the second solenoid valve 902 is fixedly connected to a connecting pipe 903. The top of the square rod 4 is fixedly connected to a reference plate 10, and the output end of the proximity light sensor 8 is aligned with the reference plate 10. A sliding opening 11 is opened in the middle of the top cover 3, and the square rod 4 is slidably connected in the sliding opening 11. The bottom end of the feed pipe 5 passes through the extrusion plate 2, and the top end of the feed pipe 5 passes through the top of the square rod 4. A valve 12 is installed at the top end of the feed pipe 5.

[0024] The overall effect of embodiment 2 is that when the air compressor 601 is working, it will draw in outside air from the air inlet. After being pressurized, the air will be delivered from the air outlet to the air inlet 602 through the connecting pipe 604. The first solenoid valve 605 can automatically open and close the exhaust pipe as needed, so that the extrusion plate 2 can move accordingly in coordination with the addition and reduction of concrete in the cylinder 1. The first solenoid valve 605 is to lock the air outlet 603 as needed. The second solenoid valve 902 can facilitate the personnel to close the grouting component 9 when it stops. The sliding port 11 is to allow the square rod 4 to slide smoothly up and down in the top cover 3. The valve 12 can open and close the feed pipe 5. When feeding is not required, the valve 12 can close the feed pipe 5.

[0025] Working principle: Before use, the extrusion plate 2 inside the cylinder 1 is at its lowest point, that is, the bottom of the reference plate 10 is in contact with the top of the top cover 3. At this time, a beam of infrared light emitted by the proximity sensor 8 shines on the bottom of the reference plate 10. Since the reference plate 10 is at its lowest point, the infrared light is reflected back and captured by the proximity sensor 8. By measuring the time, the distance between the reference plate 10 and the proximity sensor 8 can be determined. This distance is the point at which the filling device needs to be stopped to add concrete. At this time, the first solenoid valve 605 is in the open state and the second solenoid valve 902 is in the closed state. When the grouting device is needed, the operator first opens valve 12 and pours concrete slurry into cylinder 1 through feed pipe 5. The concrete slurry first fills the grouting assembly 9 at the bottom of cylinder 1 until both the grouting assembly 9 and the bottom of cylinder 1 are filled. Then, the continuously supplied concrete slurry gradually increases, slowly pushing the extrusion plate 2 upwards until it contacts the bottom of the top cover 3. At this point, cylinder 1 is filled, and filling can be stopped. Valve 12 is then closed, and the first solenoid valve 605 is closed. During the slow upward movement of the extrusion plate 2, the gas above it will exit through outlet 603 and the second solenoid valve 605. A solenoid valve 605 and an exhaust pipe discharge from the cylinder 1. When personnel start the grouting device for grouting operations, a second solenoid valve 902 opens, and the grouting assembly 9 and air compressor 601 begin to work. The grouting assembly 9 forces the concrete slurry inside the cylinder 1 through the second solenoid valve 902 into the connecting pipe 903, delivering concrete to another connected grouting head. The air compressor 601 coordinates with the conveying speed of the grouting assembly 9 to deliver high-pressure air into the cylinder 1 at an appropriate speed. The high-pressure air is delivered between the top cover 3 and the extrusion plate 2. Under the combined action of the high-pressure air and the gradually decreasing amount of concrete inside the cylinder 1, the concrete is extruded... Plate 2 will be squeezed downwards by high-pressure air, so that the gradually decreasing concrete is still in a compressed state. At the same time, the squeezing plate 2 can scrape the inner wall of the cylinder 1 to solve the problem of concrete sticking to the wall. As the squeezing plate 2 moves downwards, the reference plate 10 also moves downwards. Under the real-time monitoring of the proximity light sensor 8, the controller can determine the amount of concrete remaining in the cylinder 1 in real time. When the value detected by the proximity light sensor 8 reaches the set warning point, the control device can receive this signal and issue a stop grouting command. The grouting component 9 will stop working and remind personnel to replenish the material.

[0026] The wiring diagram of the air compressor 601, the first solenoid valve 605, the proximity light sensor 8, the second solenoid valve 902, and the separately provided control device in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the air compressor 601, the first solenoid valve 605, the proximity light sensor 8, and the second solenoid valve 902 will not be explained in detail. In summary, the problems raised in the background above are solved.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
