[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0020] like Figure 1-3 As shown, there are straightening wheels in the straightening mechanism, and an opening is provided at the front of the straightening mechanism to facilitate workers to shovel away steel chips.

[0021] A steel scrap collection device for straightening steel bars comprises a collection mechanism arranged at the lower part of the straightening mechanism, the straightening mechanism comprises a straightening bin 1, the collection mechanism comprises a collection bin 4, a collection bag 11 and a suction fan 12, the collection bin 4 is provided with a first air inlet 15 and a first air outlet 5, the first air inlet 15 is connected to the straightening bin 1 through an air duct 14, and the first air outlet 5 is connected to the suction fan 12; a plurality of collection bags 11 are arranged in the collection bin 4. The suction fan 12 sucks air with steel scraps into the collection bag 11, the collection bag 11 filters the air, the steel scraps remain in the collection bag 11, and the clean air is discharged through the suction fan 12.

[0022] Specifically, a second air outlet 13 is provided at the bottom of the straightening bin 1 , one end of the air duct 14 is connected to the second air outlet 13 , and the other end of the air duct 14 is connected to the first air inlet 15 , thereby realizing the connection between the straightening bin 1 and the collecting bin 4 .

[0023] Specifically, the collecting bin 4 is a funnel-shaped bin body that is larger at the top and smaller at the bottom.

[0024] Since the steel rod 6 and the outlet of the straightening bin 1 are most worn, the steel scraps are accumulated in the corners, which makes it inconvenient for the suction fan 12 to suck the steel scraps into the collection bag 11. Therefore, the utility model provides a guide plate 8 in the straightening bin 1 and below the straightening hole 7. The upper end of the guide plate 8 is fixed to the side wall of the straightening bin 1, and the lower end of the guide plate 8 is fixed to the bottom plate 2 of the straightening bin 1. In this way, the fallen steel scraps slide down along the guide plate 8 and will not accumulate in the corners, which makes it convenient for the suction fan 12 to suck the steel scraps into the collection bag 11.

[0025] The utility model is provided with a support keel 3 in the collection bag 11, which plays a certain supporting role for the collection bag 11, and a retaining ring 111 is provided on the top of the support keel 3; a support plate 9 is horizontally provided in the straightening bin 1, and the retaining ring 111 is overlapped on the support plate 9; a through hole 91 for placing the collection bag 11 is provided on the support plate 9. Two support plates 10 are fixed to the lower part of the support plate 9 and located on the side wall of the straightening bin 1, and the support plate 9 is overlapped on the support plate 10.

[0026] When there are too many steel chips in the collecting bag 11 and it needs to be replaced, lift the keel upwards, take out the collecting bag 11 and the keel, pour the steel chips in the collecting bag 11 to a suitable position, then reinstall the collecting bag 11 and overlap the retaining ring 111 on the support plate 9.

[0027] If the three collecting bags 11 in the utility model need to be replaced, the support plate 9 together with the three supporting keels 3 and the collecting bag 11 can be taken out, and then the steel filings in the collecting bag 11 are poured to a suitable position, and then the collecting bag 11 is reinstalled, and the support plate 9 is overlapped on the support plate 10.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model. The scope of protection required by the utility model is defined by the attached claims and their equivalents.
