[0003] The currently used waste steel shearing devices still have the following problems: 1. After the shearing blade moves once, generally only one shearing can be performed, and it is impossible to automatically shear other-shaped waste steels when the shearing blade moves upward, reducing the shearing efficiency of waste steel; 2. The length of the shearing blade is usually greater than the length of the waste steel, resulting in the inability to fully utilize different positions of the shearing blade, reducing the service life of the shearing blade. At the same time, during long-term shearing, the shearing blade cannot be automatically cooled intermittently; 3. Although some waste steel shearing devices have a moving effect, when the waste steel shearing device moves to the use area, it cannot be effectively braked, resulting in the instability of the waste steel shearing device during use.

When the output shafts of the four linear electric cylinders B407 extend out by half, the two waste steels 500 can be in contact with the front and rear ends of the T-shaped shear blade 303. Also, since the four helical springs A406 are sleeved outside the four circular guide shafts 403, and the four helical springs A406 are located between the two U-shaped brackets 402 and the four circular positioning discs 405. When the output shafts of the four linear electric cylinders B407 extend out completely, the two waste steels 500 can be in contact with the center of the T-shaped shear blade 303. On the one hand, different positions of the T-shaped shear blade 303 can be fully utilized, improving the service life of the T-shaped shear blade 303.

[0026] In the embodiment of the present disclosure, as Figure 1 、 Figure 9 and Figure 10 shown, the collection mechanism 600 includes: a circular guide rod 601 and a movable collection box 602; there are four circular guide rods 601 in total, and the four circular guide rods 601 are fixedly installed on the movable support frame 101; the movable collection box 602 is slidably installed on the movable support frame 101 and the four circular guide rods 601; the collection mechanism 600 further includes: a stepping force-receiving plate 603 and a circular stabilizing rod 604; there are two stepping force-receiving plates 603 in total, and the two stepping force-receiving plates 603 are fixedly installed on the left and right sides of the movable collection box 602; there are two rows of circular stabilizing rods 604 in total, and the two rows of circular stabilizing rods 604 are fixedly installed on the bottom of the movable collection box 602; the collection mechanism 600 further includes: a helical spring B605 and an L-shaped isolation plate 606; there are four helical springs B605 in total, and the four helical springs B605 are sleeved outside the four circular guide rods 601, and the four helical springs B605 are located below the movable collection box 602; the L-shaped isolation plate 606 is fixedly installed on the front side of the movable collection box 602, and the left and right sides of the L-shaped isolation plate 606 are aligned with the left and right sides of the control panel 200, and the top of the L-shaped isolation plate 606 is aligned with the top of the control panel 200; when the bottom of the movable collection box 602 is in contact with the movable support frame 101, the top of the L-shaped isolation plate 606 is aligned with the bottom of the control panel 200; Its specific function is as follows: because the movable collection box 602 is slidably mounted on the movable support frame 101 and the four circular guide rods 601, the sheared scrap steel 500 is collected. When the T-shaped shear knife 303 cuts off two scrap steels 500, the gravity of the outer ends of the four halves of the scrap steel 500 is greater than the gravity of the inner ends of the four halves of the scrap steel 500, so that the cut scrap steel 500 can automatically fall into the movable collection box 602; and because the L-shaped isolation plate 606 is fixedly mounted on the front side of the movable collection box 602, and the left and right sides of the L-shaped isolation plate 606 are aligned with the left and right sides of the control panel 200, and the L-shaped The top of the isolation plate 606 is aligned with the top of the control panel 200. When the staff needs to press the control panel 200, the L-shaped isolation plate 606 needs to be separated from the control panel 200 first. When the staff steps down on the two pedal force plates 603, the two rows of circular stabilizing bars 604 are inserted into the soil in the construction area, and the friction between the two rows of circular stabilizing bars 604 and the soil is greater than the elastic force of the four coil springs B605, ensuring that before the equipment is used, the two rows of circular stabilizing bars 604 must first be inserted into the soil in the construction area, which plays an auxiliary limiting effect and makes the movable support frame 101 more stable after moving.

[0027] The specific usage and function of this embodiment are as follows: When the present invention is used, the staff first moves the device through the four rollers at the bottom of the movable support frame 101 to the construction area. When the staff needs to press the control panel 200, the L-shaped isolation plate 606 needs to be separated from the control panel 200. When the staff steps down on the two pedal force plates 603, the two rows of circular stabilizing bars 604 are inserted into the soil in the construction area, and the friction between the two rows of circular stabilizing bars 604 and the soil is greater than the elastic force of the four spiral springs B605, ensuring that before the device is used, the two rows of circular stabilizing bars 60 4 must first be inserted into the soil of the construction area, which plays an auxiliary limiting effect, making the movable support frame 101 more stable after moving; then the staff will place the scrap steel 500 to be sheared between the four linear electric cylinders B407 and the four circular positioning plates 405, and then press the positioning button on the control panel 200. When the positioning button on the control panel 200 is pressed, the output shafts of the four linear electric cylinders B407 extend halfway. At this time, the two scrap steels 500 can contact the front and rear ends of the T-shaped shear knife 303; then press the shear button on the control panel 200. The cut button is pressed. At this time, the output shafts of the two linear electric cylinders A301 extend out, and the T-shaped shear knife 303 automatically moves downward, realizing the automatic shearing of the two scrap steels 500; when the T-shaped shear knife 303 cuts the two scrap steels 500, the gravity of the outer ends of the four halves of the scrap steel 500 is greater than the gravity of the inner ends of the four halves of the scrap steel 500, so that the cut scrap steel 500 can automatically fall into the movable collection box 602; when it is necessary to cut round steel, the staff can place the round steel in the two rectangular positioning seats 102, and then press the control panel 20 again. 0, at this time, the output shafts of the two linear electric cylinders A301 are retracted, and at the same time, the output shafts of the four linear electric cylinders B407 are all retracted. When the output shafts of the two linear electric cylinders A301 are retracted, the T-shaped shear knife 303 automatically moves upward, practicing the automatic shearing of the round steel, which is convenient for the staff to shear the round steel; the setting of the two arc-shaped auxiliary plates 103 supports the round steel after shearing, avoids the round steel after shearing from falling, and is convenient for the staff to place the round steel separately, thereby improving the recovery accuracy of the steel; Then, place the waste steel 500 to be sheared between the four linear electric cylinders B407 and the four circular positioning discs 405. Then, press the positioning button on the control panel 200. When the positioning button on the control panel 200 is pressed again, the output shafts of the four linear electric cylinders B407 all extend. At this time, the two pieces of waste steel 500 can contact the center of the T-shaped shear blade 303. On the one hand, different positions of the T-shaped shear blade 303 can be fully utilized, improving the service life of the T-shaped shear blade 303. On the other hand, the shearing positions are different, realizing the intermittent cooling of the T-shaped shear blade 303, which is beneficial to the long-term operation of the T-shaped shear blade 303 and reduces the self-heat of the T-shaped shear blade 303. At the same time, the two pieces of waste steel 500 are both in an elastic clamping state under the action of the four spiral springs A406, and when the output shafts of the four linear electric cylinders B407 extend by half, the four spiral springs A406 can also provide sufficient elastic positioning effect.
