Description

Technical Field

[0001] This utility model relates to the field of concrete technology, specifically a concrete spraying machine with a rebound material collection function. Background Technology

[0002] In the traditional field of concrete spraying operations, the handling of rebound material has always been a thorny issue, seriously affecting construction efficiency and cost-effectiveness. The current mainstream method for rebound material recycling is to lay a collection cloth or plastic film at the bottom of the sprayed surface, relying on the natural accumulation of rebound material on its surface for collection.

[0003] Shotcrete operations require a high degree of construction continuity. During spraying, rebound material continuously falls onto the collection fabric surface. However, due to the limited construction pace, it is impossible to clean up the rebound material before it initially sets. Especially in high-temperature or low-humidity environments, the initial setting time of cement-based materials is shortened, making the rebound material prone to rapid solidification and clumping on the collection fabric. Once clumped, the rebound material cannot be directly reused in concrete mixing, resulting in significant waste of raw materials such as cement and aggregates, and increasing construction costs. Even if collected in a timely manner, the rebound material is prone to mixing with impurities during the collection process, which affects the quality of its subsequent reuse.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a concrete spraying machine with a rebound material collection function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a concrete spraying machine with a rebound material collection function, including a spraying pipe, a sleeve clamped to the outer wall of the spraying pipe, six sliders slidably installed on the outer wall of the sleeve, a push rod abutting the side end of each of the six sliders, a threaded ring fixedly installed on the side end of each of the six push rods, a hollow tube threadedly connected to the inner wall of the threaded ring, a drive disc slidably abutting the outer wall of the hollow tube, and the inner wall of the hollow tube slidably connected to the outer wall of the spraying pipe; A connecting plate is fixedly installed on the side of the slider away from the top rod. A conical collecting plate is fixedly installed on the side end of the connecting plate. The inner wall of the conical collecting plate is connected to the inner wall of the connecting plate. A connecting groove is opened on the outer wall of the connecting plate. The outer walls of the six connecting plates abut against each other and are connected through the connecting groove. A suction pipe is fixedly installed on the inner wall of the bottom connecting plate. A suction machine is fixedly installed at the end of the suction pipe. The end of the suction machine is connected to the inner wall of the spray pipe.

[0007] Furthermore, the sleeve surface is provided with six sliding grooves, and the inner wall of each sliding groove is slidably connected to the outer wall of the push rod and the slider; A drive groove is provided on the outer wall of the end of the hollow tube away from the sleeve, and the inner wall of the drive groove slides against the outer wall of the drive disc.

[0008] Furthermore, a filter screen with a diameter of 5 mm is installed on the surface of the conical collecting plate; The hollow tube has a threaded groove on its surface, and the inner wall of the threaded groove is threadedly connected to the inner wall of the threaded ring.

[0009] Furthermore, a telescopic tube is fixedly installed on the side end of the straw, and another straw is fixedly installed on the side end of the telescopic tube.

[0010] Furthermore, each of the six slider sidewalls is rotatably mounted with two connecting rods, and a fixed rod is rotatably mounted at the end of each connecting rod away from the slider. The sidewall of the fixed rod abuts against a stop rod, and the end of the stop rod is slidably mounted on the outer wall of the sleeve. The sidewall of the stop rod abuts against the end of the top rod. A spring is fixedly connected to the side of the stop rod away from the top rod, and the spring end is fixedly connected to the sidewall of the slider.

[0011] Furthermore, the side wall of the drive disc is fixedly connected to the motor drive end, the outer wall of the motor is fixedly connected to the outer wall of the nozzle, and a retaining ring is fixedly installed at the end of the nozzle away from the motor, with the side wall of the retaining ring engaging with the end of the sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By setting up a conical collecting plate, the rebound material can be captured by the conical collecting plate after rebounding during the spraying process, enter the inner wall of the connecting plate, and then re-enter the spray pipe through the suction pipe and telescopic pipe and the suction machine to continue to participate in the spraying operation. This avoids the problem of rebound material quickly solidifying and clumping on the collecting cloth, so that the rebound material can be recycled and reused in a timely manner, improving the utilization rate of raw materials such as cement and aggregates and reducing construction costs. The conical collecting plate directly captures the rebound material and guides it into the collection system, reducing the chance of the rebound material coming into contact with external impurities, thereby ensuring the purity of the rebound material and improving the quality of its subsequent reuse.

[0015] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a concrete spraying machine with rebound material collection function, including a spray pipe 1, a sleeve 4 clamped to the outer wall of the spray pipe 1, and six sliders 6 slidably installed on the outer wall of the sleeve 4. The six sliders 6 are evenly distributed around the sleeve 4, and a conical collecting plate 5 is installed on the connecting plate 5 connected to each slider 6, so that the conical collecting plate 501 can capture rebound material from multiple directions, expanding the collection range. No matter which direction the rebound material bounces, there is a corresponding conical collecting plate 501 to intercept it, improving efficiency. To improve the collection efficiency of rebound material, each of the six sliders 6 has a push rod 3 abutting its side end. A threaded ring 301 is fixedly installed on the side end of each of the six push rods 3. A hollow tube 2 is threadedly connected to the inner wall of the threaded ring 301. A drive disc 102 slides against the outer wall of the hollow tube 2. The inner wall of the hollow tube 2 is slidably connected to the outer wall of the nozzle 1. A connecting plate 5 is fixedly installed on the side of the slider 6 away from the push rod 3. A conical collecting plate 501 is fixedly installed on the side end of the connecting plate 5. The inner wall of the conical collecting plate 501 communicates with the inner wall of the connecting plate 5. A connecting groove 502 is provided on the outer wall of the connecting plate 5. The outer walls of the six connecting plates 5 abut against each other and are connected by the connecting groove 502. The inner wall of the bottom connecting plate 5 is fixedly installed with a suction pipe 7, which is connected to the suction machine 8. The suction machine 8 is connected to the inner wall of the nozzle 1. This connected design forms a complete collection loop. The rebound material captured by the conical collection plate 501 can smoothly enter the interior of the connecting plate 5 through the connecting groove 502, and then be transported back to the nozzle 1 through the suction pipe 7 and the suction machine 8, so as to realize the recycling of the rebound material.

[0017] Please see Figure 2This utility model provides a technical solution: a concrete spraying machine with a rebound material collection function, comprising six sliders 6, each with two connecting rods 601 rotatably mounted on its sidewall. A fixed rod 602 is rotatably mounted on the end of each connecting rod 601 away from the slider 6. A stop rod 603 abuts against the sidewall of the fixed rod 602. The end of the stop rod 603 is slidably mounted on the outer wall of the sleeve 4. The sidewall of the stop rod 603 abuts against the end of a top rod 3. A spring 604 is fixedly connected to the side of the stop rod 603 away from the top rod 3. The side end of the spring 604 is connected to the slider 6. With a fixed connection at the side end, during overall operation, the abutment rod 603 drives the spring 604 to push the slider 6 to slide. When the slider 6 moves to the abutment position, the spring 604 is compressed. At this time, the abutment rod 603 abuts against the fixed rod 602 and pushes the fixed rod 602 out. Since the length of the conical collecting plate 501 is one meter, in the combined state, the six conical collecting plates 501 extend out of the top of the nozzle 1, so that the distance between the nozzle 1 and the spraying surface can be kept at more than one meter. Within this distance range, a better spraying effect can be obtained when spraying concrete.

[0018] Please see Figure 2 This utility model provides a technical solution: a concrete spraying machine with a rebound material collection function, including a sleeve 4 with six sliding grooves 401 on its surface. The inner wall of each sliding groove 401 is slidably connected to the outer wall of the top rod 3 and the slider 6, providing a precise moving track for the top rod 3 and the slider 6 to realize the opening and closing of the conical collection plate 501, ensuring that the top rod 3 and the slider 6 slide accurately along the predetermined direction and ensuring the stable operation of the device.

[0019] Please see Figure 2 This utility model provides a technical solution: a concrete spraying machine with a rebound material collection function, including a drive disc 102 whose side wall is fixedly connected to the drive end of a motor 101. Since the outer wall of the motor 101 is fixedly connected to the outer wall of the spray pipe 1, the motor 101 is installed on the spray pipe 1. The spray pipe 1, as one of the main support structures of the device, provides a stable installation foundation for the motor 101. A retaining ring 103 is fixedly installed at the end of the spray pipe 1 away from the motor 101. The side wall of the retaining ring 103 is engaged with the end of the sleeve 4.

[0020] Please see Figure 2 This utility model provides a technical solution: a concrete spraying machine with a rebound material collection function, including a drive groove 201 opened on the outer wall of the hollow tube 2 away from the sleeve 4. Since the drive disc 102 rotates under the drive of the motor 101, its outer wall slides against the inner wall of the drive groove 201 on the hollow tube 2, so that the rotational power of the drive disc 102 can be directly and efficiently transmitted to the hollow tube 2, thereby realizing the power transmission function carried by the sliding contact action between the inner wall of the drive groove 201 and the outer wall of the drive disc 102.

[0021] Please see Figure 2This utility model provides a technical solution: a concrete spraying machine with a rebound material collection function, including a hollow tube 2 with a threaded groove 202 on its surface, the inner wall of the threaded groove 202 being threadedly connected to the inner wall of the threaded ring 301, a telescopic tube 701 being fixedly installed on the side end of the suction tube 7, and another suction tube 7 being fixedly installed on the side end of the telescopic tube 701.

[0022] Working principle: When the motor 101 is started, the drive end of the motor 101 drives the drive disk 102 to rotate. The drive disk 102 slides in the drive groove 201 of the hollow tube 2, and drives the hollow tube 2 to rotate through friction. The threaded groove 202 on the outer wall of the hollow tube 2 engages with the threaded ring 301. As the hollow tube 2 rotates, the threaded ring 301 begins to move and drives the push rod 3 to slide in the sliding groove 401 on the outer wall of the sleeve 4. The movement of the push rod 3 drives the abutment rod 603 to move. The spring 604 on the side wall of the abutment rod 603 drives the slider 6 to slide in the sliding groove 401, which in turn drives the connecting plate 5 and the conical collecting plate 501 to move synchronously. When the side end of the slider 6 abuts against the end of the inner wall of the sliding groove 401, due to the continuous rotation of the hollow tube 2, the threaded ring 301 drives the abutment rod 603 to hold. The continuous movement of the spring 604 compresses the abutment rod 603. When the end of the abutment rod 603 abuts against the fixed rod 602, the continuous movement of the abutment rod 603 will push the fixed rod 602 to move towards the sleeve 4, causing the six connecting plates 5 to move forward and approach each other until the side walls of the six connecting plates 5 are in contact with each other, the six conical collecting plates 501 are also in contact with each other, and the connecting grooves 502 are connected to each other. At this time, the distance between the edge of the conical collecting plate 501 and the surface to be sprayed is adjusted to 20 to 30 cm, and the spraying operation can be carried out. At the same time, the suction machine 8 is started. During the spraying process, the rebound material is captured by the conical collecting plate 501 after rebounding, enters the inner wall of the connecting plate 5, and then re-enters the spray pipe 1 through the suction pipe 7 and the telescopic pipe 701 connected to the side end of the suction pipe 7 and the suction machine 8 to continue to participate in the spraying operation.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
