[0021] The protective device 200 includes a motor 210, an outer cover 220 and a connecting frame 230. The motor 210 is connected to the moving end of the first electric push rod 111 through a second mounting frame 211. The second mounting frame 211 and the moving end of the first electric push rod 111 are fixed by bolts.

The outer cover 220 is sleeved on the outside of the cutting blade 213 and is connected to the outer wall of the motor 210 through a connecting rod. The connecting rod is connected to the motor 210. The outer wall of the outer cover 220 is fixed by bolts, the other end of the connecting rod is welded to the outer wall of the outer cover 220, the outer wall of the outer cover 220 is welded with a first connecting frame 221, the bottom of the connecting frame 230 is connected to the second electric push rod 112, the two connecting frames 230 and the second electric push rod 112 are symmetrically distributed on both sides of the outer cover 220, the bottom of the connecting frame 230 is connected to the second connecting frame 231, and a folding cover 232 is fixed between the second connecting frame 231 and the first connecting frame 221 by bolts, and the folding cover 232 is located above the discharge hole 121;

[0022] In this technical solution, the motor 210 is used to provide power for driving the cutting blade 213, so that the cutting blade 213 can cut the steel bars, the connecting frame 230 is used to cover the upper half of the cutting blade 213, and the second connecting frame 231 and the folding cover 232 are used in combination to cover the lower half of the cutting blade 213, and the second electric push rod 112 and the connecting frame 230 are used to control the movement of the second connecting frame 231 in the vertical direction. Finally, the outer cover 220, the folding cover 232 and the discharge hole 121 form a chamber connected to the inner cavity of the discharge box 130.

[0023] In some technical solutions, reference Figure 1-2A mounting groove vertically distributed with the discharge hole 121 is opened at the top of the mounting seat 120, and a first mounting frame 140 is inserted into the interior of the mounting seat 120. The first mounting frame 140 can be slidably connected with the mounting seat 120. A clamping block 142 is fixed to the top of the inner cavity of the first mounting frame 140 by bolts, and the clamping block 142 is located directly above the mounting groove.

[0024] In this technical solution, the third electric push rod 141 is used to control the vertical movement of the first installation frame 140. When the steel bars are placed horizontally into the installation groove, the third electric push rod 141 pushes the first installation frame 140 to move downward as a whole, so that the clamping block 142 applies pressure to the steel bars, so that the steel bars are stably clamped in the installation groove, waiting to be cut by the cutting blade 213.

[0025] In some technical solutions, reference Figure 1 , Figure 3 and Figure 4 A column 122 is welded between the top of the mounting seat 120 and the bottom surface of the top of the mounting frame 110.

A guide groove that can be slidably connected to the guide block 212 is opened on the side of the column 122 close to the second mounting frame 211.

[0026] In this technical solution, the coordinated use of the column 122 and the guide block 212 can control the movement trajectory of the second installation frame 211, so that the second installation frame 211 can always move in the vertical direction to avoid tilting during movement and affecting the cutting of the steel bars.

[0027] In some technical solutions, reference Figure 1 , Figure 3 and Figure 4 An arc ring is welded in the middle of the second connection frame 231, and the inner side wall of the arc ring is evenly inlaid with blocking strips 233.

[0028] In this technical solution, both the arc ring and the installation groove are semi-arc structures, the diameter of the arc ring is larger than the diameter of the installation groove, and the maximum diameter of the steel bar cut is the diameter of the installation groove. When the steel bar is installed in the installation groove, the blocking bar 233 will be compressed and bent and placed in the middle of the steel bar and the arc ring. The setting of the blocking bar 233 can not only allow the gas to flow into the inner cavity of the outer cover 220 normally, but also prevent sparks from splashing out through the gap.

[0030] In this technical solution, the use of the telescopic column 222 can control the moving trajectory of the second connecting frame 231, so that the second connecting frame 231 can be horizontally attached to the surface of the mounting base 120, avoiding the second connecting frame 231 from forming an angle with the mounting base 120 during movement, thereby preventing smoke from overflowing outward from the gap between the second connecting frame 231 and the mounting base 120.

[0031] Working principle: first connect the third electric push rod 141, the exhaust fan 131, the second electric push rod 112, the first electric push rod 111, the motor 210 with the external control device and the power supply, place the steel bar horizontally in the installation slot, and operate the control switch of the third electric push rod 141, the third electric push rod 141 pushes the first installation frame 140 to move downward, so that the clamping block 142 contacts the steel bar, that is, the locking of the steel bar position is completed. According to the use requirements, a first installation frame 140 and a third electric push rod 141 can be symmetrically distributed on both sides of the discharge hole 121 to jointly position and clamp the steel bar; then operate the control switches of the second electric push rod 112 and the exhaust fan 131, the exhaust fan 131 continuously exhausts the inner cavity of the discharge box 130, and the second electric push rod 112 pushes the second connecting frame 231 to move downward through the connecting frame 230, so that the second connecting frame 23 When the outer cover 220, the folding cover 232 is horizontally in contact with the surface of the mounting seat 120, the unfolding of the folding cover 232 is completed, so that the outer cover 220, the folding cover 232 and the discharge hole 121 form a chamber connected with the discharge box 130, and the external gas enters the inner cavity of the outer cover 220 through the gap between the arc ring and the steel bar. At this time, the control switch of the motor 210 and the first electric push rod 111 is operated again, the motor 210 drives the cutting blade 213, and the first electric push rod 111 pushes the motor 210 downward, so that the cutting blade 213 contacts the steel bar until the steel bar is cut off. A large amount of sparks and smoke will be generated when the steel bar is cut, and the sparks and smoke will enter the inner cavity of the discharge box 130 under the action of the airflow, and enter the filter bag 132 with the airflow for filtration, so that the sparks and smoke generated when the steel bar is cut can be shielded to prevent the sparks and smoke from floating around.
