Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of auxiliary equipment for steel bar bending, and relates to a dust collection device for a steel bar leveling mechanism. Background Technology
[0002] During tunnel construction, the secondary lining of the tunnel needs to be bound into a steel cage using steel bars. The steel bars used inside the secondary lining need to be bent and cut. With the improvement of automation, automatic steel bar bending and cutting devices have been gradually developed. The steel bars can be bent and cut simply by feeding them into the equipment. However, before feeding them in, because the steel bars are in a disc shape, they are driven by the drive wheel and fed into the equipment through a straightening and leveling mechanism for bending and cutting, and then discharged from the outlet. When the steel bars pass through the straightening and leveling mechanism, they are in close contact with it, which causes friction or scraping on the surface of the steel wires, generating dust that falls directly to the ground, affecting environmental hygiene. Excessive dust can also fly everywhere when there is airflow disturbance. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a dust collection device for a rebar leveling mechanism, which can collect the generated dust and ash to avoid affecting the working environment.
[0004] The technical solution adopted by this utility model is as follows: a ash collection device for a rebar leveling mechanism, including a hopper and a collection plate. The collection plate is installed obliquely on the back of the leveling mechanism. The collection plate has a trough-shaped structure. The hopper is installed at the lower end of the collection plate. A detachable collection bucket is connected to the lower end of the hopper.
[0005] Furthermore, a branch pipe is connected to one side of the discharge pipe of the aforementioned hopper, and a micro-negative pressure exhaust fan is connected to the branch pipe. The power shaft of the micro-negative pressure exhaust fan is connected to the roller shaft of the leveling mechanism through a belt drive mechanism.
[0006] Furthermore, a baffle cavity is provided at the connection point between the branch pipe and the discharge pipe, and a mesh is opened at the bottom of the baffle cavity.
[0007] Furthermore, a filter sponge block is provided at the aforementioned mesh opening, and the filter sponge block is provided with a square frame. The square frame is inserted into the opening provided on the side of the discharge pipe and then placed on the mesh opening at the bottom of the baffle cavity.
[0008] Furthermore, the aforementioned aggregate plate is connected to the mounting frame of the leveling mechanism via four connecting rods.
[0009] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model greatly improves the dust collection effect and reduces the possibility of environmental pollution by installing a grooved collecting plate on the back of the flattening mechanism and cooperating with the collecting action of the hopper.

[0013] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0014] Example 1: As Figures 1-3 As shown, a dust collection device for a rebar leveling mechanism includes a dust collection hopper 1 and a dust collection plate 2. The dust collection plate 2 is installed obliquely on the back of the leveling mechanism 3. The dust collection plate 2 has a trough-shaped structure. The dust collection hopper 1 is installed at the lower end of the dust collection plate 2. A detachable dust collection bucket 4 is connected to the lower end of the dust collection hopper 1. The leveling mechanism 3 is installed at the inlet of the rebar bending and cutting device. In use, the rebar 17 is fed into several sets of straightening wheels of the leveling mechanism 3 and then fed into the drive wheel set 16. Under the rotation of the drive wheel set 16, the rebar is pulled out from the rebar rack and enters the leveling mechanism for leveling and straightening.
[0015] In order to draw as much dust and debris as possible into the collection bin, a branch pipe 5 is connected to one side of the discharge pipe 12 of the collection hopper 1. The branch pipe 5 is connected to a micro negative pressure exhaust fan 6. The power shaft of the micro negative pressure exhaust fan 6 is connected to the roller shaft 7 of the leveling mechanism 3 through a belt drive mechanism 18. The micro negative pressure exhaust fan generates a negative pressure effect under the slow and intermittent rotation of the roller shaft, thereby drawing as much dust as possible into the collection bin and improving the dust and debris collection effect.
[0016] To reduce the possibility of dust being sucked into the exhaust fan, a baffle 8 is provided at the connection between the branch pipe 5 and the discharge pipe 12. The bottom of the baffle 8 has a mesh 9. Through the blocking effect of the baffle, the probability of dust entering the branch pipe is reduced.
[0017] To reduce dust entering the exhaust fan, a filter sponge block 10 is installed at mesh 9. The filter sponge block 10 is equipped with a square frame 11. The square frame 11 is sealed and inserted through the opening 13 on the side of the discharge pipe 12 and placed on the mesh 9 at the bottom of the baffle cavity 8. The dust is filtered by the sponge block, preventing it from being drawn into the exhaust fan under slight negative pressure. The square frame provides stable and reliable support and is easy to install and disassemble.
[0018] To ensure a stable and reliable connection, the aggregate plate 2 is connected to the mounting frame 15 of the leveling mechanism 3 by four connecting rods 14. The connecting rods are bent rods or inclined rods, and both ends are bolted to the mounting frame and the side wall of the aggregate plate, providing stable and reliable support.
[0019] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
