Description

Technical Field

[0001] This utility model relates to the field of concrete placing machine technology, and more specifically, to a concrete placing mechanism for processing precast concrete slabs. Background Technology

[0002] A vibrating placing boom, also known as a vibrating feeder, is a device that can uniformly, regularly, and continuously feed lumpy or granular materials from a storage silo to a receiving device. In sand and gravel production lines, vibrating placing booms can continuously and uniformly feed crushing machinery and perform coarse screening of materials, and are widely used in building materials, chemical, and other industries. For example, the vibrating feeding device for concrete products proposed in publication number "CN218808442U" includes: two sets of parallel first frames; a second frame, the second frame being welded to the side of the first frames, a vibrating motor fixedly mounted on the second frame, the output end of the vibrating motor being connected to a connecting rod, under the action of the vibrating motor, the connecting rod being able to rotate or vibrate, and the other end of the connecting rod being movably connected to a third frame, so that the third frame can rotate with the connecting rod. This invention enables the fourth frame to vibrate under the action of a vibrating motor, allowing the concrete on the fourth frame to be transferred from one end to the other, thus speeding up the transfer of the mixed concrete from one end to the user's predetermined position and reducing the workload of the construction personnel. However, in the above technical solution, when the above vibrating feeder is in use, it is easy for some materials to pile up on top of other materials in the hopper, resulting in material accumulation. When the thickness of the material accumulation is large, the hopper cannot feed the material evenly through the vibrating motor set on its lower surface, causing the production line to be paralyzed. Utility Model Content

[0003] The main purpose of this utility model is to provide a material feeding mechanism for processing precast concrete slabs, which can effectively solve the problem in the background art where, when using a vibrating feeder, some materials easily pile up on top of other materials in the hopper, causing material accumulation. When the thickness of the material accumulation is large, the hopper cannot feed the material evenly through the vibrating motor set on its lower surface, leading to the paralysis of the production line.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A material feeding mechanism for processing precast concrete slabs includes a hopper, two spring supports are provided on both sides of the hopper, and a vibration motor is provided on the lower surface of the hopper; Two brackets are fixedly installed on one side of the hopper, and a lead screw is rotatably installed between the two brackets. A movable seat is threaded on one side of the lead screw, and a right-angle frame is installed on one side of the movable seat. An installation groove is opened on the top surface of the right-angle frame, and a support plate is installed in the installation groove. A scraper is fixedly installed on one side of the support plate. One of the brackets is fixedly mounted on one side with a first motor, and one end of the lead screw passes through the corresponding bracket and is fixedly connected to the output shaft end of the first motor.

[0005] Preferably, a slide bar is fixedly installed between the two brackets, and the movable seat is slidably disposed on one side of the slide bar.

[0006] Preferably, a rotating rod is rotatably installed between the two sides of the inner wall of the mounting groove, and the support plate is sleeved on the rotating rod.

[0007] Preferably, one end of the rotating rod passes through the right-angle frame and is fitted with a first gear; The right-angle bracket has a second motor fixedly mounted on the side near the first gear via a mounting plate. The output shaft of the second motor is fitted with a second gear, and the first gear meshes with the second gear.

[0008] Preferably, the movable seat has a groove on the surface near the right-angle frame, and a slider is slidably disposed in the groove, with one side of the slider being fixedly connected to the right-angle frame. A positioning rod is fixedly installed between the two sides of the inner wall of the groove, and the slider is slidably disposed on one side of the positioning rod.

[0009] Preferably, a guide column is rotatably mounted on one side of the right-angle frame; A guide plate is fixedly installed on one side of both brackets. A guide groove is opened through one side surface of the guide plate, and the guide column is movably disposed in the guide groove.

[0010] Compared with the prior art, the present invention has the following beneficial effects: (1) When the staff starts the first motor, the output shaft of the first motor drives the lead screw to rotate. The rotating lead screw drives the moving seat and the right angle frame to move along the slide bar by screwing in the thread, so that the scraper moves along the inside of the hopper and scrapes the stacked material to avoid the accumulation of material. This prevents the hopper from being able to feed the material evenly through the vibration motor set on its lower surface, which causes the production line to be paralyzed.

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0014] like Figures 1-6 As shown in the figure, this utility model embodiment proposes a material feeding mechanism for processing precast concrete slabs, including a hopper 1, two spring supports 2 on both sides of the hopper 1, and a vibration motor 3 on the lower surface of the hopper 1. Two brackets 4 are fixedly installed on one side of the hopper 1. A screw 5 is rotatably installed between the two brackets 4. A movable seat 6 is threaded on one side of the screw 5. A right-angle frame 7 is installed on one side of the movable seat 6. An installation groove 8 is opened on the top surface of the right-angle frame 7. A support plate 9 is installed in the installation groove 8. A scraper 10 is fixedly installed on one side of the support plate 9. One of the brackets 4 has a first motor 11 fixedly installed on one side, and one end of the lead screw 5 passes through the corresponding bracket 4 and is fixedly connected to the output shaft end of the first motor 11.

[0015] A slide rod 12 is fixedly installed between the two brackets 4, and a movable seat 6 is slidably disposed on one side of the slide rod 12.

[0016] When the worker starts the vibrating motor 3, the hopper 1 vibrates continuously under the combined action of the vibrating motor 3 and the spring support 2, causing the material inside the hopper 1 to move continuously along the inclined surface of the hopper 1, thereby achieving continuous feeding. The worker starts the first motor 11, and the output shaft of the first motor 11 drives the lead screw 5 to rotate. The rotating lead screw 5 drives the moving seat 6 and the right-angle frame 7 to move along the slide rod 12 through the screw thread, so that the scraper 10 moves along the inside of the hopper 1 and scrapes the stacked material to avoid the material from accumulating. Otherwise, the hopper 1 will not be able to feed the material evenly through the vibrating motor 3 set on its lower surface, causing the production line to be paralyzed.

[0017] In another embodiment of this utility model, a rotating rod 13 is rotatably installed between the two sides of the inner wall of the mounting groove 8, and a support plate 9 is sleeved on the body of the rotating rod 13.

[0018] One end of the rotating rod 13 passes through the right-angle bracket 7 and is fitted with the first gear 14; The right-angle bracket 7 is fixedly mounted with the second motor 1501 on the side near the first gear 14 via the mounting plate 15. The output shaft of the second motor 1501 is fitted with the second gear 16, and the first gear 14 meshes with the second gear 16.

[0019] After the scraper 10 moves to its original position, the operator starts the second motor 1501, which drives the second gear 16 to rotate. The rotating second gear 16 meshes with the first gear 14, causing the first gear 14 to drive the rotating rod 13 to rotate. This causes the support plate 9 and the scraper 10 to swing with the rotating rod 13, allowing the scraper 10 to pour the material back into the feeding position of the hopper 1. This eliminates the need for the operator to manually put the material accumulated on the surface of the scraper 10 back into the hopper 1, reducing the operator's workload.

[0020] In another embodiment of the present invention, a groove 17 is provided on the surface of the movable seat 6 near the right angle frame 7, and a slider 18 is slidably disposed in the groove 17, with one side of the slider 18 fixedly connected to the right angle frame 7. A positioning rod 19 is fixedly installed between the two sides of the inner wall of the slide groove 17, and a slider 18 is slidably disposed on one side of the positioning rod 19.

[0021] A guide column 20 is rotatably mounted on one side of the right-angle bracket 7; Two brackets 4 are fixedly installed on one side with guide plates 21. A guide groove 22 is opened through one side surface of the guide plate 21, and the guide column 20 is movably set in the guide groove 22.

[0022] When the guide column 20 moves within the guide groove 22 provided on one side surface of the guide plate 21, the right-angle frame 7 is not easily deviated due to external force under the limiting effect of the guide groove 22. The scraper 10 can move stably within the hopper 1 and scrape the stacked material. When the guide column 20 moves to a more inclined slope position within the guide groove 22, the guide column 20 is pushed by the slope at this point, causing the right-angle frame 7 to move along the slide 17 and the scraper 10 to rise, thus preventing the scraper 10 from colliding with the material inside the hopper 1 or the inner wall of the hopper 1 when it rotates.

[0023] The working principle of a fabrication mechanism for processing precast concrete slabs: In use, the operator starts the vibrating motor 3. With the cooperation of the vibrating motor 3 and the spring support 2, the hopper 1 vibrates continuously, causing the material inside the hopper 1 to move continuously along the inclined surface of the hopper 1, thereby achieving continuous feeding. The operator starts the first motor 11. The output shaft of the first motor 11 drives the lead screw 5 to rotate. The rotating lead screw 5 drives the moving seat 6 and the right-angle frame 7 to move along the slide rod 12 through the screw thread. This causes the scraper 10 to move along the inside of the hopper 1 and scrape the stacked material to prevent the material from accumulating. Otherwise, the hopper 1 will not be able to feed the material evenly through the vibrating motor 3 set on its lower surface, which could lead to the paralysis of the production line.

[0024] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
