Description

Technical Field

[0001] The invention relates to the technical field of pouring devices, in particular to a concrete pipe raw material pouring device. Background Art

[0002] Concrete pipes are a commonly used infrastructure material in the construction field. The key to producing high-quality concrete pipes lies in the processing and pouring of concrete raw materials. Concrete raw material pouring is the process of putting concrete into the mold until it is plasticized. It includes raw material input, mixing, transportation and pouring molding. Each link directly affects the quality and performance of concrete structures or components.

[0003] During the concrete mixing process, if the concrete raw materials contain large particles of gravel, it is easy to affect the uniformity and quality of the concrete, resulting in uneven strength and poor durability of the produced concrete pipes. In addition, existing mixing devices usually only rely on simple rotary mixing, which makes it difficult to fully mix the raw materials in all directions, easily leading to insufficient mixing, thereby affecting the mixing effect of the concrete. Therefore, a concrete pipe raw material pouring device is provided to improve the above-mentioned problems. Summary of the Invention

[0004] The object of the present invention is to provide a concrete pipe raw material pouring device. By providing a crushing component and a stirring component, the present invention solves the problem that if the concrete raw materials contain large particles of stone during the concrete mixing process, the uniformity and quality of the concrete will be easily affected, resulting in uneven strength and poor durability of the produced concrete pipes. In addition, existing stirring devices usually rely only on simple rotary stirring, which makes it difficult to fully mix the raw materials in all directions, which easily leads to insufficient stirring and thus affects the mixing effect of the concrete.

[0005] The present invention is achieved through the following technical solutions:

[0006] The present invention is a concrete pipe raw material pouring device, comprising a mixing barrel, a crushing assembly, a mixing assembly and a pouring assembly, wherein a barrel cover is hingedly connected to the mixing barrel, the barrel cover is connected to a feed hopper, the crushing assembly is arranged on the feed hopper, the crushing assembly comprises a crushing plate, a first crushing roller, a second crushing roller and a belt, the crushing plate is installed on the feed hopper, tooth grooves are provided on both sides of the crushing plate, a gap is left between the first crushing roller and the tooth groove on one side, a gap is left between the second crushing roller and the tooth groove on the other side, and belts are connected to the first crushing roller and the second crushing roller. The pulleys are connected by a belt. The stirring assembly is arranged on the barrel cover. The stirring assembly includes a round rod and a round ring. A round plate is installed at one end of the round rod. A circle of horizontal plate is installed on the round plate. A rotating shaft is rotated on the horizontal plate. A gear is connected to the rotating shaft. A gear ring is installed on the inner wall of the ring. The gear is engaged with the gear ring. A stirring blade, a scraper and an auger stirring blade are respectively installed on the rotating shaft. The stirring blade has a serrated edge. The scraper slides and fits with the inner wall of the mixing barrel. The bottom of the mixing barrel is connected to a discharge pipe, and the pouring assembly is connected to the bottom of the discharge pipe.

[0007] Furthermore, two first through holes and two second through holes are provided on the feed hopper, the two ends of the first crushing roller are respectively rotatably engaged with the two first through holes, the two ends of the second crushing roller are respectively rotatably engaged with the two second through holes, the first crushing roller is installed with the power output shaft of the driving source, and the driving source is arranged on the feed hopper.

[0008] Furthermore, the ring is installed on the barrel cover, a first circular hole is opened on the barrel cover, the round rod is rotatably matched with the first circular hole, and the other end of the round rod is connected to the power output shaft of the driving source, and the driving source is set on the barrel cover.

[0009] Furthermore, an annular hole is provided at the bottom of the barrel cover, and the rotating shaft is rotatably engaged with the annular hole.

[0010] Furthermore, the barrel cover is hollow inside, and the circular plate, the horizontal plate and the circular ring are all located inside the barrel cover.

[0011] Furthermore, a second circular hole is provided on the horizontal plate, and the rotating shaft is rotatably engaged with the second circular hole.

[0012] Furthermore, the casting assembly includes a discharge box, which is connected to the discharge pipe, a discharge hose is connected to the opening of the discharge box, and a vibration motor is installed on the side wall of the discharge box.

[0013] Furthermore, the discharge box is arranged at an inclination.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention provides a crushing assembly. By starting a DC motor, the DC motor's power output shaft drives the first crushing roller to rotate. The first crushing roller then drives the second crushing roller to rotate synchronously via a belt and pulley. Because both the first and second crushing rollers have gaps between their teeth and the tooth grooves, the two crushing rollers crush the raw materials entering the feed hopper, breaking larger stones into smaller particles. This solves the problem of large stones in the concrete raw materials affecting the uniformity and quality of the concrete during the mixing process, resulting in uneven strength and poor durability of the produced concrete pipes.

[0016] 2. The present invention provides a stirring assembly, and by starting a three-phase asynchronous motor, the power output shaft of the three-phase asynchronous motor drives the round rod, the round plate and the cross plate to rotate. Since the gear on the rotating shaft is engaged with the gear ring, the rotating shaft rotates around the round rod and the stirring blades, scraper and auger stirring blades on the rotating shaft move accordingly. The serrated edges of the stirring blades can effectively mix the raw materials during the stirring process, and the auger stirring blades can cause the raw materials to produce axial movement, thereby achieving sufficient stirring of the raw materials and making the concrete more uniform. This solves the problem that existing stirring devices usually rely only on simple rotary stirring, which makes it difficult to fully mix the raw materials in all directions, easily resulting in insufficient stirring, thereby affecting the stirring effect of the concrete;

[0017] 3. The present invention provides a stirring assembly that uses a rotating shaft to drive a scraper to scrape off the raw materials attached to the inner wall of the mixing drum. This solves the problem that a large amount of raw materials are easily attached to the inner wall of the mixing drum. If these attached raw materials are not cleaned, it will not only affect the subsequent mixing effect, but may also breed bacteria and impurities, affecting the quality of concrete.

[0018] 4. The present invention provides a pouring assembly and starts a vibration motor, which generates vibration to make the concrete in the discharge box more compact and reduce bubbles in the concrete. At the same time, the vibration can also promote the flow of concrete in the inclined discharge box and the discharge hose to prevent concrete blockage, thereby solving the problem that concrete is prone to blockage during the discharge process. At the same time, bubbles may be generated in the concrete during the discharge process, reducing the density and strength of the concrete.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-7 The present invention provides a technical solution: a concrete pipeline raw material pouring device, comprising a mixing barrel 1, a crushing component 4, a mixing component 5 and a pouring component 7. A support frame is welded to the outer wall of the mixing barrel 1, and the support frame is used to support the entire device. A barrel cover 2 is hinged on the mixing barrel 1, which is convenient for opening and closing the mixing barrel 1 and facilitating equipment maintenance and cleaning. At the same time, the presence of the barrel cover 2 can reduce the entry of dust and debris during the mixing process, thereby ensuring the quality of the concrete. A feed hopper 3 is connected to the barrel cover 2 by welding, and the feed hopper 3 provides a channel for the input of raw materials, so that the raw materials can smoothly enter the mixing barrel 1.

[0030] The crushing assembly 4 is arranged on the feed hopper 3, and the crushing assembly 4 includes a crushing plate 401, a first crushing roller 403, a second crushing roller 404 and a belt 406. The crushing plate 401 is installed on the feed hopper 3 by welding. Tooth grooves 402 are provided on both sides of the crushing plate 401. There is a gap between the first crushing roller 403 and the tooth groove 402 on one side, and there is a gap between the second crushing roller 404 and the tooth groove 402 on the other side. The size of the gap can be set according to actual needs. When driven by a DC motor, it rotates to perform preliminary crushing on the raw materials entering the feed hopper 3, and crush larger particles of stone into smaller particles, which is beneficial to the full mixing of the raw materials in the subsequent mixing process and improves the quality and uniformity of the concrete. The first crushing roller 403 and the second crushing roller 404 are both connected with pulleys 405, and the two pulleys 405 are connected by a belt 406. The two pulleys 405 are connected by the belt 406 to realize the synchronous rotation of the first crushing roller 403 and the second crushing roller 404.

[0031] Two first through holes 301 and two second through holes 302 are provided on the feed hopper 3. The two ends of the first crushing roller 403 are rotatably engaged with the two first through holes 301 through bearings respectively. The outer ring of the bearing is fixedly installed in the first through hole 301, and the inner ring of the bearing is rotatably engaged with the first crushing roller 403. The two ends of the second crushing roller 404 are rotatably engaged with the two second through holes 302 through bearings respectively. The outer ring of the bearing is fixedly installed in the second through hole 302, and the inner ring of the bearing is rotatably engaged with the second crushing roller 404. The first through hole 301 and the second through hole 302 provide space for installation and rotation of the first crushing roller 403 and the second crushing roller 404. The first crushing roller 403 is installed with the power output shaft of the driving source through a coupling. The driving source can select an adapted DC motor, which is mounted on the feed hopper 3 by bolts.

[0032] The stirring assembly 5 is arranged on the barrel cover 2. The stirring assembly 5 includes a round rod 501 and a round ring 506. A round plate 502 is installed on one end of the round rod 501 by welding. The round plate 502 rotates with the rotation of the round rod 501, providing a platform for installation and support for the horizontal plate 503. A circle of horizontal plates 503 are installed on the circular plate 502 by welding. The horizontal plate 503 provides support and installation position for the rotating shaft 504, so that the rotating shaft 504 can rotate on the horizontal plate. The rotating shaft 504 is rotatably matched on the horizontal plate 503. A second round hole 511 is opened on the horizontal plate 503. The rotating shaft 504 is rotatably matched with the second round hole 511 through a bearing. The outer ring of the bearing is fixedly installed in the second round hole 511, and the inner ring of the bearing is rotatably matched with the rotating shaft 504. A gear 505 is connected to the rotating shaft 504 by a key, and a gear ring 507 is installed on the inner wall of the ring 506 by welding. When the gear 505 is engaged with the gear ring 507, the rotating shaft The stirring blade 508, scraper 509 and auger stirring blade 510 are respectively installed on the rotating shaft 504 by bolts. The auger stirring blade 510 can generate axial thrust when rotating, so that the raw materials in the mixing barrel 1 not only have circumferential movement but also axial movement, which further improves the mixing degree of the raw materials and makes the concrete more uniform. The stirring blade 508 has a serrated edge, which can more effectively mix the raw materials during the mixing process, enhance the mixing effect, and make the concrete more uniform. The scraper 509 slides and fits with the inner wall of the mixing barrel 1. The scraper 509 can scrape off the raw materials attached to the inner wall of the mixing barrel 1 during the mixing process to avoid the accumulation of raw materials on the barrel wall, ensure the adequacy of the mixing, and also facilitate the cleaning of the mixing barrel 1.

[0033] The top of the ring 506 is mounted on the barrel cover 2 by bolts. The ring 506 provides an installation position for the gear ring 507, and also provides support and guidance for the rotation of the rotating shaft 504. A first circular hole 201 is opened on the barrel cover 2. The round rod 501 rotates with the first circular hole 201 through a bearing. The outer ring of the bearing is installed in the first circular hole 201, and the inner ring of the bearing rotates with the round rod 501. The other end of the round rod 501 is connected to the power output shaft of the driving source through a coupling. The driving source can be an adapted three-phase asynchronous motor. The three-phase asynchronous motor is mounted on the L-shaped plate by bolts, and the L-shaped plate is mounted on the barrel cover 2 by bolts.

[0034] An annular hole 202 is provided at the bottom of the barrel cover 2, and the rotating shaft 504 rotates in cooperation with the annular hole 202. The annular hole 202 provides a precise guide for the rotation of the rotating shaft 504, thereby preventing the rotating shaft 504 from deflecting and making the operation of the mixing assembly 5 more stable. The barrel cover 2 is hollow inside, and the circular plate 502, the horizontal plate 503 and the circular ring 505 are all located inside the barrel cover 2. The hollow setting can provide protection for the circular plate 502, the horizontal plate 503, the rotating shaft 504, the gear 505, the circular ring 506 and the gear ring 507, thereby preventing the concrete in the mixing barrel 1 from affecting these components and improving the service life of these key components.

[0035] The bottom of the mixing barrel 1 is connected to a discharge pipe 6 by welding. A valve is installed on the flange of the discharge pipe 6. The discharge pipe 6 is used to connect the mixing barrel 1 and the discharge box 701. It is the channel for conveying concrete from the mixing barrel 1 to the discharge box 701, ensuring the smooth flow of materials. The casting assembly 7 is connected to the bottom of the discharge pipe 6 by welding.

[0036] The pouring assembly 7 includes a discharge box 701, which is connected to the discharge pipe 6 by welding. The discharge box 701 is tilted, which is conducive to the concrete flowing to the discharge hose 702 by its own gravity, reducing the need for additional power. At the same time, the discharge box 701 provides a buffer and temporary storage space for the concrete, so that the concrete can enter the discharge hose 702 more stably. The opening of the discharge box 701 is connected to the discharge hose 702 through a quick-release joint. The discharge hose 702 has the characteristics of being movable and flexible, which is convenient for transporting concrete to the position where pouring is required, and adapts to different construction environments and pouring requirements. A vibration motor 703 is installed on the side wall of the discharge box 701 by bolts. The vibration motor 703 can generate vibration to make the concrete in the discharge box 701 more compact, reduce bubbles in the concrete, and improve the pouring quality of the concrete. At the same time, vibration can also promote the flow of concrete in the discharge box 701 and the discharge hose 702 to prevent concrete blockage.

[0037] During operation, firstly, the concrete pipe raw materials are poured into the feed hopper 3, and the DC motor is started through the external controller, so that the power output shaft of the DC motor drives the first crushing roller 403 to rotate through the coupling. Since the first crushing roller 403 and the second crushing roller 404 have gaps with the tooth groove 402, and the second crushing roller 404 is driven to rotate synchronously through the belt 406 and the pulley 405, the two crushing rollers crush the raw materials entering the feed hopper, and crush the larger particles of stone into smaller particles. Then the raw materials pass through the feed hopper 3 and enter the mixing barrel 1, and then the three-phase asynchronous motor is started through the external controller, so that the power output shaft of the three-phase asynchronous motor drives the round rod 501 to rotate through the coupling, and the round rod 501 drives the circular plate 502 and the horizontal plate 503 to rotate. Since the gear 505 on the rotating shaft 504 is engaged with the gear ring 507 on the inner wall of the ring 506, the rotating shaft While 504 rotates around the round rod 501, it also rotates itself, and the stirring blades 508, scrapers 509 and auger stirring blades 510 on the rotating shaft 504 move accordingly. The stirring blades 508 mix the raw materials, the scrapers 509 scrape the raw materials on the inner wall of the mixing barrel 1, and the auger stirring blades 510 cause the raw materials to move axially, thereby achieving sufficient stirring of the raw materials in the mixing barrel 1 and making the concrete more uniform. After the mixing is completed, the valve on the discharge pipe 6 is opened to allow the mixed concrete to flow into the discharge box 701 through the discharge pipe 6. The vibration motor 703 is started by the external controller to make the concrete in the discharge box 701 more compact and promote its flow. The concrete flows to the discharge hose 702 through the inclined discharge box 701. The operator can move the discharge hose 702 as needed to transport the concrete to the position where it needs to be poured for pouring operations.
