A vibrating feeder for making sand from construction waste

Abstract

This utility model discloses a vibrating feeding device for sand making from construction waste, including a frame. A hollow rotating shaft is rotatably mounted on the frame, with an air inlet pipe installed at one end. The input end of the air inlet pipe is connected to a blowing device. Several blowing pipes are installed on the hollow rotating shaft and communicate with the interior of the hollow rotating shaft. An exhaust pipe is installed on the frame, with its output end connected to a negative pressure device. A drive mechanism for driving the hollow rotating shaft to rotate is installed on the frame. Several push plates are hinged to the hollow rotating shaft. The arrangement of the blowing pipes and push plates allows for the stirring and leveling of accumulated raw materials, resulting in more uniform subsequent screening. The blowing pipes expel air during stirring, blowing away dust, which is then discharged through the exhaust pipe, thus preventing most dust from entering the machine. The mounting frame facilitates disassembly and maintenance of the hollow rotating shaft, and the arc-shaped plate improves the efficiency of the blowing pipes in blowing away dust.

Description

Technical Field

[0001] This utility model relates to the technical field of vibrating feeder for sand making from construction waste, and in particular to a vibrating feeder for sand making from construction waste. Background Technology

[0002] When existing vibrating feeders are in use, the raw materials may accumulate and be screened unevenly. This results in sand particles that have reached the required size and dust from the material being transported to the sand making machine, causing the sand particles to be processed repeatedly. The dust will reduce the service life of the sand making machine. Utility Model Content

[0003] Therefore, it is necessary to provide a construction waste sand making vibrating feeder to address the technical problems of uneven screening and dust reducing the lifespan of the sand making machine.

[0004] To achieve the above objectives, this utility model provides a vibrating feeder for sand making from construction waste, comprising a frame, a hollow shaft rotatably mounted on the frame, an air inlet pipe installed at one end of the hollow shaft, the input end of the air inlet pipe being connected to a blowing device, a plurality of blowing pipes installed on the hollow shaft, the blowing pipes communicating with the interior of the hollow shaft, an exhaust pipe installed on the frame, the output end of the exhaust pipe being connected to a negative pressure device, a drive mechanism for driving the hollow shaft to rotate installed on the frame, a plurality of push plates hinged to the hollow shaft, and a spring installed on the hollow shaft, the output end of the spring being connected to the push plates.

[0005] Preferably, a mounting bracket is installed on the frame, and a driven plate is snapped onto one end of the hollow rotating shaft away from the air intake pipe. The driven plate is rotatably mounted on the mounting bracket, and an arc-shaped plate is installed on the mounting bracket, with the arc-shaped plate located inside the hollow rotating shaft.

[0009] Preferably, the driving mechanism includes a rotary driving device, a first gear is installed on the air intake pipe, and a second gear is installed at the output end of the rotary driving device, with the first gear and the second gear meshing together.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0011] 1. The air blowing pipe and push plate can stir and flatten the accumulated raw materials, making the subsequent screening of raw materials more uniform; the air blowing pipe blows air outward during stirring, which can blow away the dust and discharge it through the exhaust pipe, thereby preventing most of the dust from entering the machine.

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Please see Figures 1 to 2This application provides a vibrating feeder for sand making from construction waste, including a frame 1, which is a vibrating feeder in the prior art, capable of conveying and feeding materials and vibrating screening. A hollow rotating shaft 2 is rotatably mounted on the frame 1 via bearings. An air inlet pipe 3 is fixedly mounted on one end of the hollow rotating shaft 2. The input end of the air inlet pipe 3 is connected to a blowing device via a rotary joint. The blowing device can be a blower or similar device. Several air blowing pipes 4 are fixedly mounted on the hollow rotating shaft 2, and the air blowing pipes 4 are connected to the hollow rotating shaft 2 via a rotary joint. The hollow shaft 2 is internally connected, and an exhaust pipe 5 is fixedly installed on the frame 1. The output end of the exhaust pipe 5 is connected to a negative pressure device, which can be a vacuum pump, etc. Before being connected to the negative pressure device, it should also undergo a process such as filtration and dust removal. A drive mechanism for driving the hollow shaft 2 to rotate is installed on the frame 1. Several push plates 6 are hinged on the hollow shaft 2. A crank spring is fixedly installed on the hollow shaft 2, and the output end of the crank spring is fixedly connected to the push plate 6. Multiple hollow shafts 2 and exhaust pipes 5 can be set according to actual needs.

[0018] In this embodiment, when the frame 1 is working, the hollow shaft 2 can be driven to rotate together via the drive mechanism. When the accumulated material conveyed by the frame 1 passes the hollow shaft 2, the hollow shaft 2 can drive the air blowing pipe 4 to stir and disperse the material, and cooperate with the push plate 6 to flatten the material, thereby avoiding uneven screening due to material accumulation. The push plate 6 can flatten the material by its own weight, and the setting of the spring increases the flattening force and prevents it from deflecting before flattening, thus affecting the flattening process. When the hollow shaft 2 drives the air blowing pipe 4 to rotate, the air blowing pipe 4 can penetrate into the material layer, thereby allowing air to enter through the air inlet pipe 3. After the airflow passes through the hollow shaft 2, it blows air through the air blowing pipe 4, which can blow up the dust at the bottom of the material layer and extract it through the exhaust pipe 5, thereby preventing most of the dust from entering the machine.

[0019] In some embodiments, to facilitate internal maintenance and improve dust removal efficiency, a mounting bracket 7 is installed on the frame 1. The two can be detachably fixed by means of a snap-fit ​​mechanism or fasteners. A driven plate 8 is snapped onto one end of the hollow rotating shaft 2 away from the air inlet pipe 3. The driven plate 8 is rotatably mounted on the mounting bracket 7 via a bearing. An arc-shaped plate 9 is installed on the mounting bracket 7 and is located inside the hollow rotating shaft 2. The driven plate 8 is rotatably mounted on the mounting bracket 7, and the driven plate 8 is engaged with the hollow rotating shaft 2. Thus, after the mounting bracket 7 is installed on the frame 1, the driven plate 8 can rotate in conjunction with the hollow rotating shaft 2. The driven plate 8 has a through hole in its center, and the arc-shaped plate 9 mounted on the mounting plate 7 extends from there into the interior of the hollow rotating shaft 2. Thus, when the air pressure inside the hollow rotating shaft 2 is relatively high and air is blown outward by the air blowing pipe 4, the arc-shaped plate 9 can cause the air blowing pipe 4 to blow air downward only, so that only the bottom dust is blown out, and no air is blown upward, so that the clean airflow presses the dust down. The arc-shaped plate 9 and the inner wall of the hollow rotating shaft 2 can be sealed together by a wear-resistant sealing gasket. The sealing degree does not need to be too high, as long as most of the airflow can be blown downward. Alternatively, the two can be fitted with a gap, and slight air leakage will not affect the operation.

[0020] In some embodiments, to facilitate the engagement of the driven plate 8 and the hollow rotating shaft 2, a locking block 10 is fixedly installed on the driven plate 8, and a locking groove 11 is provided on the hollow rotating shaft 2. The locking block 10 and the locking groove 11 are configured to cooperate with each other. By locking the locking block 10 into the locking groove 11, the driven plate 8 is able to rotate in coordination with the hollow rotating shaft 2.

[0021] In some embodiments, to facilitate disassembly and maintenance of the arc-shaped plate 9, a second slot 12 is provided on the mounting bracket 7, and a second locking block 13 is fixedly installed on the arc-shaped plate 9. The second slot 12 and the second locking block 13 are configured to cooperate, and the second locking block 13 is rotatably and sealingly installed in the driven plate 8. The second locking block 13 and the driven plate 8 can be rotatably and sealingly connected by a wear-resistant sealing gasket, or they can be fitted with a gap. Slight air leakage will not affect the operation. The second locking block 13 is inserted into the second slot 12, and then the mounting bracket 7 can be installed.

[0022] In some embodiments, to facilitate the assembly and disassembly of the mounting bracket 7, the mounting bracket 7 is fixedly mounted on the frame 1 by bolts and fasteners 14.

[0023] In some embodiments, to facilitate driving the hollow shaft 2 to rotate, a drive mechanism is provided including a rotary drive device 15. The rotary drive device 15 can be a customized low-speed servo motor. A gear 16 is fixedly mounted on the air intake pipe 3. The air intake pipe 3 is connected to a blower via a rotary joint at a distance from the gear 16. A gear 17 is fixedly mounted on the output end of the rotary drive device 15. The gear 16 and the gear 17 are meshed together. The rotary drive device 15 drives the gear 17 to rotate. Through the meshing of the gear 16 and the gear 17, the hollow shaft 2 can be rotated by the gear 16.

[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0025] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
