[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The invention provides a vertical crusher with a multiple crushing unit structure.

[0022] First embodiment: Please combine Figures 1 to 8 , a vertical crusher with a multiple crushing unit structure, comprising a bottom plate 1, a first crushing mechanism 3, a sorting mechanism 4, a second crushing mechanism 5 and a third crushing mechanism 6; The upper surface of the bottom plate 1 is fixedly provided with a mounting frame 2, and the first crushing mechanism 3 includes a first crushing box 31, and a driving motor 32 is installed on the outer wall of the first crushing box 31 by bolts, and a driving pulley 33 is connected to the output shaft keyway of the driving motor 32, and a driving gear 34 is connected to the output shaft of the driving motor 32 and the keyway located in front of the driving pulley 33, and two first crushing rollers 35 are installed inside the first crushing box 31, and a driven gear 37 is rotatably connected to the outer wall of the first crushing box 31 and located on one side of the driving motor 32; See also Figure 3 and Figure 4: The user starts the driving motor 32 to rotate clockwise, and the driving motor 32 will drive the driving gear 34 to rotate clockwise. At the same time, the driving gear 34 engages and controls the driven gear 37 to rotate counterclockwise.

[0023] See also Figure 5 When the driving gear 34 and the driven gear 37 rotate relative to each other, the two first crushing rollers 35 are driven to rotate in mesh with each other inside the first crushing box 31, so that the electronic waste can be crushed in meshing manner.

[0024] The sorting mechanism 4 includes a feed frame 41 fixed to the lower surface of the first crushing box 31, and the front and rear sides of the feed frame 41 are fixed with limit plates 42 by bolts, and the opposite sides of the two limit plates 42 are rotatably connected with a driving roller 43 and a magnetic roller 45, respectively, and the outer wall of one of the limit plates 42 is rotatably connected with a driven pulley 44, and the outer walls of the driving pulley 33 and the driven pulley 44 are sleeved with a transmission belt 36, and the outer walls of the driving roller 43 and the magnetic roller 45 are sleeved with a microporous belt 46, and the magnetic roller 4 5, a first pulley 47 is connected to the keyway at the axis of the two limit plates 42, a conveyor belt 48 is installed on the opposite side of the two limit plates 42 and below the microporous belt 46, a second pulley 49 is connected to the axis of the conveyor belt 48 and at a keyway in a vertical direction to the first pulley 47, a connecting belt 410 is sleeved on the outer walls of the first pulley 47 and the second pulley 49, a first magnetic plate 411 and a second magnetic plate 412 are respectively provided on the inner wall of the microporous belt 46, and the second magnetic plate 412 is located below the first magnetic plate 411; See also Figure 3 and Figure 6 : The electronic waste products crushed by the first crushing box 31 will fall from the unloading frame 41 onto the microporous belt 46. At the same time, the clockwise rotation of the driving motor 32 will drive the driving pulley 33 to rotate clockwise, affecting the transmission belt 36 to drive the driven pulley 44 to rotate and control the driving roller 43 to rotate counterclockwise, so that the microporous belt 46 can be controlled to transmit from the left side to the right side; The microporous belt 46 will synchronously affect the rotation of the magnetic roller 45 during the transmission process, and the magnetic roller 45 will drive the first pulley 47 to affect the connecting belt 410 to control the second pulley 49 to control the entire conveyor belt 48 to maintain the same direction of transmission as the microporous belt 46.

[0025] See also Figure 7 : The waste material falling on the microporous belt 46 is a mixture of iron and plastic. The mixed waste material can be conveyed by the microporous belt 46 through the first magnetic plate 411 and the magnetic roller 45. Through magnetic attraction, the iron waste material will remain on the surface of the microporous belt 46, and the plastic waste material will be conveyed from the microporous belt 46 and finally fall on the conveyor belt 48; The iron waste will be attracted by the magnetic roller 45 on the microporous belt 46 , and then pass through the second magnetic plate 412 , and finally lose the magnetic attraction at the left extreme position of the second magnetic plate 412 and fall into the inside of the second pulverizing mechanism 5 .

[0026] The second pulverizing mechanism 5 comprises a second pulverizing box 51 fixedly mounted on the lower surface of the unloading frame 41, a second motor 52 is mounted on the outer wall of the second pulverizing box 51 by bolts, a first gear 53 is connected to the keyway of the output shaft of the second motor 52, a second gear 55 is rotatably connected to the outer wall of the second pulverizing box 51 and located on one side of the first gear 53, and two second pulverizing rollers 54 are rotatably connected to the interior of the second pulverizing box 51; The third crushing mechanism 6 includes a third crushing box 61, the outer wall of the third crushing box 61 is rotatably connected to a third gear 62 and a fourth gear 63, the third gear 62 is connected to a fourth pulley 64 at a keyway at the axis, the second gear 55 is connected to a third pulley 56 at a keyway at the axis, the outer walls of the third pulley 56 and the fourth pulley 64 are sleeved with a connecting belt 65, and the interior of the third crushing box 61 is rotatably connected to two third crushing rollers 66.

[0027] See also Figure 8 : Iron waste will fall into the second crushing box 51, and plastic waste will fall into the third crushing box 61. The second motor 52 is started to rotate clockwise, so that the first gear 53 and the second gear 55 can be controlled to rotate relative to each other. When the second gear 55 rotates, it will affect the third pulley 56 and affect the connecting belt 65 to control the fourth pulley 64 to make the third gear 62 and the fourth gear 63 rotate. In this way, the second crushing roller 54 can be controlled to crush the iron alone, and the third crushing roller 66 can be controlled to crush the plastic waste.

[0028] The mounting frame 2 is installed with bolts to the first crushing box 31, the second crushing box 51 and the third crushing box 61. Two corresponding trolleys 9 are provided on the upper surface of the base plate 1 and below the second crushing box 51 and the third crushing box 61. The driving gear 34 and the driven gear 37 are meshed with each other. The axis centers of the driving gear 34 and the driven gear 37 are keyed to the axis centers of the two first crushing rollers 35, and the two first crushing rollers 35 are meshed with each other.

[0029] The axis of the driven pulley 44 is connected to the keyway of the driving roller 43 , the first pulley 47 is rotatably connected to the limit plate 42 , and both sides of the first magnetic plate 411 and the second magnetic plate 412 are fixedly mounted to the limit plate 42 .

[0030] The first gear 53 and the second gear 55 are meshed with each other, and the axis of the first gear 53 and the second gear 55 is connected to the key groove of the two second crushing rollers 54. The third gear 62 and the fourth gear 63 are meshed with each other, and the axis of the third gear 62 and the fourth gear 63 is connected to the key groove of the two third crushing rollers 66.

[0031] It can be understood that: since the lengths of the first magnetic plate 411 and the second magnetic plate 412 are different, the iron waste directly falling on the microporous belt 46 is directly and quickly attracted, and the length design of the second magnetic plate 412 can ensure that the iron waste falls accurately into the second crushing box 51.

[0032] This embodiment: Compared with the traditional design, this case adopts the first pulverizing mechanism 3 to roughly pulverize the electronic products, and adopts the sorting mechanism 4 to sort the roughly pulverized waste, and can perform separate magnetic sorting on iron and plastic, so that the two materials of different density and strength can be pulverized separately for secondary treatment. Therefore, such a design can not only perform multiple pulverization treatments, but also realize the independent pulverization of two materials during the multiple pulverization process, and can pulverize more finely. Secondly, it can also directly realize the integrated linkage of pulverization and classification.

[0033] Second embodiment: See also Figure 4 , Figure 5 and Fig. 9 The first crushing box 31 is provided with a material turning mechanism 7 inside, and the outer wall of the first crushing box 31 and the two sides of the driving motor 32 are fixedly provided with a limit sleeve 71, and the inside of the limit sleeve 71 is provided with a slidable slide rod 75 through a knob, and the inner wall of the first crushing box 31 is slidably connected with a flap 72 on both sides, and the inside of the flap 72 is provided with a slidable elastic plate 74 through a spring, and the lower surface of the flap 72 is fixedly provided with a return spring 73; The return spring 73 is arranged in an arc shape; A rotating plate 76 is fixedly mounted on the outer wall of the two first pulverizing rollers 35 . A reset plate 77 is rotatably mounted on the outer wall of the rotating plate 76 via a coil spring. A guide wheel 78 is rotatably connected to the bottom of the reset plate 77 .

[0034] See also Figure 4 and Figure 5 : During the working process of the first crushing mechanism 3, the user can freely start the material turning mechanism 7 to work or not work. If the material turning mechanism 7 is not needed, the user needs to slide the slide bar 75 along the inner part of the first crushing box 31 in the limiting sleeve 71 to push the elastic plate 74 to move inside the flap 72, and finally when the elastic plate 74 completely enters the flap 72; When the first crushing roller 35 rotates, the rotating plate 76 is driven to rotate without contacting the flap 72 , so the first crushing roller 35 can rotate to avoid the flap 72 , thereby achieving the non-operation of the material turning mechanism 7 .

[0035] See also Fig. 9 (a) in the figure: the flap 72 which is always in a stationary state can play a good role in blocking the material, thereby preventing the incompletely crushed material from entering the sorting mechanism 4 below.

[0036] See also Fig. 9 (b) in it: When the turning mechanism 7 is working, the rotating rotating plate 76 will drive the reset plate 77 to control the guide wheel 78 to contact the flap 72, and then the flap 72 will be driven by the force to turn over, so that the waste material falling on the flap 72 can be turned over and sent to the first crushing roller 35 for crushing again.

[0037] The top of the return spring 73 is fixedly connected to the inner wall of the first crushing box 31 , and one end of the slide rod 75 extending into the first crushing box 31 contacts the outer wall of the elastic plate 74 .

[0038] It can be understood that the strength of the coil spring at the rotating position between the reset plate 77 and the rotating plate 76 is greater than the strength of the reset spring 73, so that the flipping movement of the flap 72 can be smoothly controlled. When the guide wheel 78 rotates to the extreme position, the rotational force is greater than the torsional force of the coil spring, which can make the reset plate 77 twist to avoid the flap 72 at the extreme position and reset it to the initial position to complete the reset.

[0039] In this embodiment: the turning mechanism 7 has two working states, and the user can freely switch between them according to the object to be crushed. The first state is that the flap 72 remains stationary, which is suitable for the crushing of small objects. The second state is a continuous reciprocating turning motion, which is suitable for the crushing of large objects. The material falling on the flap 72 is turned over to the first crushing roller 35 for secondary crushing. This can ensure that the crushing is more thorough and avoid incompletely crushed material falling on the sorting mechanism 4.

[0040] Third embodiment: See also Figure 3 and Fig.10 , further comprising a cleaning mechanism 8; The cleaning mechanism 8 includes a ratchet 81 , and the outer wall of the limiting plate 42 is rotatably connected to a gear ring 82 , one side of the gear ring 82 is meshedly connected to a connecting gear 83 , and a brush roller 84 is connected to a keyway at the axis of the connecting gear 83 .

[0041] The axis of the ratchet wheel 81 is connected to the keyway of the driving roller 43 , the outer wall of the ratchet wheel 81 and the inner wall of the gear ring 82 are meshed with each other, and the outer wall of the brush roller 84 is in contact with the outer wall of the microporous belt 46 .

[0042] See also Figure 3 and Fig.10 : When the crushing is in progress, the first crushing rollers 35 mesh with each other. If the material is stuck, the user needs to reversely rotate the first crushing rollers 35 to rotate toward the outside to guide the stuck material out. And during the crushing process, the microporous belt 46 is in a conveying state, so that when the driving roller 43 rotates, it affects the avoidance between the ratchet wheel 81 and the gear ring 82, and at this time the brush roller 84 is not in a stationary state; If the material is stuck, the microporous belt 46 will be affected by the reverse transmission. During the transmission process, the ratchet 81 will be driven to rotate, and the image gear ring 82 will rotate to engage and control the connecting gear 83 to control the brush roller 84 to rotate to clean the microporous belt 46.

[0043] This embodiment: During the operation of the first embodiment, if material jams inside the first pulverizing roller 35, the first pulverizing rollers 35 are controlled to rotate toward the outside in the reverse direction to allow the jammed material inside to be discharged. At the same time, the cleaning mechanism 8 is started to work, and the brush roller 84 can continuously brush the microporous belt 46, so that the fine jammed chips in the microporous belt 46 can be removed and processed, ensuring that the subsequent microporous belt 46 can stably absorb the iron waste, and at the same time, the surface of the microporous belt 46 can be made cleaner.

[0044] Please refer to Figures 1 to 10 The working principle of a vertical crusher with a multiple crushing unit structure provided by the present invention is as follows: Step S1: primary crushing work; First, before work, the user needs to place the base plate 1 in a safe environment, and then put the electronic waste to be crushed from the top of the first crushing box 31, start the drive motor 32 to rotate clockwise, and the drive motor 32 will drive the drive gear 34 to rotate clockwise. At the same time, the drive gear 34 engages to control the driven gear 37 to rotate counterclockwise. When the drive gear 34 and the driven gear 37 rotate with each other, they will drive the two first crushing rollers 35 to rotate with each other inside the first crushing box 31, so that the electronic waste can be crushed in an engaging manner.

[0045] Step S2: The electronic waste products crushed by the first crushing box 31 will fall from the unloading frame 41 onto the microporous belt 46. At the same time, the clockwise rotation of the driving motor 32 will drive the driving pulley 33 to rotate clockwise, affecting the transmission belt 36 to drive the driven pulley 44 to rotate and control the driving roller 43 to rotate counterclockwise, so that the microporous belt 46 can be controlled to transmit from the left side to the right side; The microporous belt 46 will synchronously affect the rotation of the magnetic roller 45 during the transmission process, and the magnetic roller 45 will drive the first pulley 47 to affect the connecting belt 410 to control the second pulley 49 to control the entire conveyor belt 48 to maintain the same direction of transmission as the microporous belt 46.

[0046] Step S3: Iron waste will fall into the second crushing box 51, and plastic waste will fall into the third crushing box 61. The second motor 52 is started to rotate clockwise, so that the first gear 53 and the second gear 55 can be controlled to rotate relative to each other. When the second gear 55 rotates, it will affect the third pulley 56 and the connecting belt 65 to control the fourth pulley 64 to make the third gear 62 and the fourth gear 63 rotate. In this way, the second crushing roller 54 can be controlled to crush the iron alone, and the third crushing roller 66 can be controlled to crush the plastic waste.

[0047] Step S4: If a material jam occurs, the microporous belt 46 will be affected by reverse transmission, and during the transmission process, the ratchet 81 will be driven to rotate, and the image gear ring 82 will rotate to engage and control the connecting gear 83 to control the brush roller 84 to rotate to clean the microporous belt 46.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
