DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1 , 2 As shown in Figures 3, 4 and 5, the utility model provides a technical solution: a scrap iron barrel crushing and recycling device, comprising: a crushing box 2, wherein two crushing rollers with multiple crushing blades 4 are rotatably arranged inside the crushing box 2 through bearings; a feeding channel 8 is installed at the bottom of the crushing box 2 through bolts, and a screen plate 17 is installed at the bottom of the feeding channel 8; an impact cleaning part is placed at a position of the feeding channel 8 corresponding to the screen plate 17, and the impact cleaning part comprises an impact plate 9 which is reciprocatingly lifted and arranged in the middle of the feeding channel 8, and a plurality of knocking parts are equidistantly arranged in the middle of the impact plate 9 for cleaning paint and impurities of the iron barrel fragments after crushing, and a cross bar 15 is connected to the top of the impact plate 9 through a guide rod 13; a power part is arranged at one side of the crushing box 2, and the power part comprises a driving motor 5 and a gear set for driving the crushing blades 4 to rotate, and a cam 7 for driving the cross bar 15 to reciprocate and lift is fixedly connected to the output end of the driving motor 5, and the cam 7 is located directly below the cross bar 15, and a plurality of rollers for cooperating with the cross bar 15 are arranged on the outer side of the cam 7.

[0025] It should be noted that the driving unit of the utility model drives the cam 7 to rotate and drives the crushing blade 4 to move toward the middle at the same time through the gear set. Under the mutual squeezing and cutting action of the crushing blades 4, the iron barrel is crushed and falls into the feeding channel 8 below. At the same time, when the end of the cam 7 away from the output shaft of the driving motor 5 is connected with the cross bar 15, the cross bar 15 is lifted up under the action of squeezing, and the cross bar 15 drives the impact plate 9 to move upward through the guide rod 13. The impact plate 9 compresses the No. 2 reset spring 14 while moving upward. When the end of the cam 7 away from the output shaft of the driving motor 5 moves to the bottom, under the elastic force of the No. 2 reset spring 14, the impact plate 9 impacts downward, and the impact plate 9 drives the knocking unit to impact the crushed material falling on the top of the screen plate 17. The paint and impurities on the outside of the fragments are separated by impact and extrusion. After the impurities and paint fall off, they pass through the sieve plate 17 and enter the bottom. The top of the sieve plate 17 is transported downward under the action of vibration. The sieve plate 17 is installed at the bottom of the discharge channel 8. The sieve plate is used to separate impurities and fragments in the crushed materials; the sieve plate 17 can effectively filter out larger impurities and incompletely crushed iron barrel fragments, while allowing impurities and small paint particles to enter the bottom through the sieve holes for subsequent cleaning; the impact plate 9 can continuously impact and vibrate the crushed materials on the sieve plate 17 through the cooperation of the cam 7 and the No. 2 return spring 14, so as to separate the paint and impurities on the surface of the iron barrel fragments, so that the fragments can be cleaned, thereby realizing the integration of crushing, separation and cleaning functions.

[0026] See also Figure 1 , 2 As shown, it also includes a support frame 1, which is installed at the bottom of the crushing box 2 by bolts, and a driving motor 5 is fixedly connected to the top of the support frame 1. Two crushing rollers are symmetrically rotated in the crushing box 2, and the crushing blades 4 outside the two crushing boxes 2 are staggered with each other. The gear set includes a driving gear 3 and a driven gear 6, and the driving gear 3 and the driven gear 6 are fixedly connected to the corresponding crushing rollers, and the output end of the driving motor 5 is fixedly connected to the driving gear 3.

[0027] It should be noted that the support frame 1 of the utility model is made of rectangular metal pipes welded together, the two crushing rollers are symmetrically rotatably arranged in the crushing box, the outer crushing blades are staggered with each other, the symmetrical crushing rollers cooperate with the staggered crushing blades, which can effectively improve the crushing efficiency and uniformity, ensure the particle size consistency of the crushed materials, and the staggered crushing blades 4 increase the crushing coverage area of ​​the materials, making each crushing action more thorough, the driving motor 5 drives the driven gear 6 to rotate through the driving gear 3, and under the meshing action of the driving gear 3 and the driven gear 6, the two crushing rollers drive the crushing blades 4 to move toward the middle at the same time, thereby realizing the synchronous movement of the crushing rollers and the consistency of the rotation speed.

[0028] See also Figure 5As shown, a plurality of limit blocks 16 are symmetrically installed on the outer side of the discharge channel 8 by bolts, and sliding rods 18 are welded to the sides of the limit blocks 16. The sliding rods 18 penetrate the sieve plate 17 and are slidably connected to the sieve plate 17. A shock-absorbing spring 19 is sleeved on the outer side of the sliding rod 18 and located below the sieve plate 17.

[0029] It should be noted that the sieve plate 17 of the utility model is tilted and arranged at the bottom of the discharge channel 8, and the limit block 16 is an L-shaped structure. The sieve plate 17 is slidably connected to the side of the limit block 16. When the knocking part applies pressure to the top of the sieve plate 17, the sieve plate 17 compresses the slide bar 18 downward. When the knocking part is reset, the sieve plate 17 is reset under the action of the slide bar 18, thereby realizing the reciprocating shaking of the sieve plate 17, so that the sieve plate 17 can screen the top material, so that large pieces of material are transported downward, and debris and impurities pass through the sieve holes of the sieve plate 17 into the collection box below the sieve plate 17.

[0030] See also Figure 3 , 4 As shown, the striking part includes a plurality of telescopic rods 10 slidably mounted in the middle of the striking plate 9, a striking ball 12 is fixedly connected to the bottom of the telescopic rod 10, and a No. 1 return spring 11 is sleeved on the outer side of the telescopic rod 10 and located between the striking plate 9 and the striking ball 12.

[0031] It should be noted that, in the utility model, under the action of the cam 7 driving the cross bar 15 to rise and fall, the guide rod 13 cooperates with the No. 2 reset spring 14 to drive the impact plate 9 to move up and down, and the impact plate 9 drives the impact ball 12 to move downward. When the impact ball 12 contacts the material below, under the action of extrusion, the impact ball 12 compresses the No. 1 reset spring 11 upward, thereby playing a buffering role, thereby avoiding serious deformation of the material and extending the service life of the screen plate 17. When the impact plate 9 rises, the No. 1 reset spring 11 drives the impact ball 12 to reset, which is convenient for the next knocking.

[0032] See also Figure 1 , 3 As shown, the middle part of the support frame 1 is slidably connected to two guide rods 13 through a limit ring, two cross bars 15 are fixed between the two guide rods 13, the bottom of the guide rod 13 is fixed to the impact plate 9, and a No. 2 return spring 14 is sleeved on the outer side of the guide rod 13 and between the limit ring and the impact plate 9.

[0033] It should be noted that a limit ring is fixedly installed in the middle of the support frame 1 of the utility model, and a linear bearing is installed inside the limit ring. The guide rod 13 is slidably connected with the linear bearing. When the cam 7 pushes the cross bar 15 upward, the cross bar 15 drives the guide rod 13 to move upward. During this period, the impact plate 9 compresses the No. 2 reset spring 14. When one end of the cam 7 is separated from the cross bar 15, under the elastic force of the No. 2 reset spring 14, the impact plate 9 drives the impact ball 12 to impact downward, and the paint layer and surface impurities fall off through vibration and impact force.

[0034] See also Figure 3 As shown, baffles 20 are fixedly connected to both sides of the impact plate 9 to prevent debris from entering the top of the impact plate 9.

[0035] It should be noted that, in the utility model, when the impact plate 9 moves downward, the baffle 20 blocks the middle of the material discharge channel 8, thereby temporarily isolating and blocking the material, preventing the crushed material from entering the top of the impact plate 9 during the impact process, causing a dead corner for cleaning.
