[0011] In some embodiments, two feeding limit sleeves are provided, and the two feeding limit sleeves are arranged on the inner side wall of the crusher housing in a side-by-side manner. On the upper end face of the feeding control plate, two feeding limit slide rods are provided, and the two feeding limit slide rods are respectively in sliding fit with the feeding limit sleeves on both sides.

[0013] In some embodiments, the processing cavity includes a feeding cavity and a crushing cavity. The feeding cavity is located above the crushing cavity. The feeding mechanism is located at the feeding cavity. The first crushing roller and the second crushing roller are located in the crushing cavity.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly: In this solution, an adjusting mechanism is provided. The adjusting mechanism on the two first driving turntables controls the distance between the axis of the first crushing roller and the axis of the first driving turntable. The second crushing roller is rotatably arranged in the processing cavity and is located between the two second driving turntables. The adjusting mechanism on the two second driving turntables controls the distance between the axis of the second crushing roller and the axis of the second driving turntable. When it is necessary to ensure the uniformity of material crushing, the axis of the first crushing roller is adjusted to be in the same straight line as the axis of the first driving turntable through the adjusting mechanism, and the axis of the second crushing roller is adjusted to be in the same straight line as the axis of the second driving turntable through the adjusting mechanism. At this time, the first driving turntable drives the first crushing roller to rotate coaxially, and the second driving turntable drives the second crushing roller to rotate coaxially. The crushing operation of the material can be realized through the mutual operation of the first crushing roller and the second crushing roller. When it is necessary to control and improve the crushing effect of the double-tooth roll crusher, it is controlled that the first crushing roller continuously impacts the second crushing roller during the continuous eccentric rotation process, so that the material passing through the first crushing roller and the second crushing roller is continuously impacted, thereby improving the crushing efficiency.

[0016] Second: The adjusting mechanism further includes adjusting bevel gears. Adjusting bevel gears are rotatably provided on the first driving turntable and the second driving turntable respectively. A synchronous gear meshing with the adjusting bevel gear is provided at the side end of the horizontal adjusting screw rod. A corresponding adjusting groove is provided on the adjusting bevel gear. The adjusting groove can be set as an internal hexagonal groove. The user can rotate the adjusting bevel gear with a hexagonal wrench. The adjusting bevel gear drives the synchronous gear to rotate, and the synchronous gear drives the horizontal adjusting screw rod to rotate, so as to adjust the first crushing roller and the second crushing roller. On this basis, this structure can also prevent the position deviation of the first crushing roller and the second crushing roller caused by the rotation of the horizontal adjusting screw rod when the adjusting mechanism rotates at a high speed.

[0017] Third: In this solution, a feeding mechanism is provided on the upper side of the crusher housing. When the feeding swing rod swings to the lower side, it drives the feeding control plate to move horizontally relative to the upper ends of the first crushing roller and the second crushing roller. At this time, the materials entering the crusher housing are blocked by the feeding control plate, reducing the feeding amount of the materials and preventing the materials between the first crushing roller and the second crushing roller from being blocked and jammed due to excessive materials. When the feeding swing rod swings to the upper side, it drives the feeding control plate to be in a relatively vertical state. At this time, the materials will smoothly enter between the first crushing roller and the second crushing roller for crushing. On this basis, when the feeding swing rod continues to swing, it drives the feeding control plate to be in a relatively horizontal state while pressing down on the materials between the first crushing roller and the second crushing roller, thereby promoting the crushing of the materials between the first crushing roller and the second crushing roller and improving the crushing efficiency.

[0038] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0039] Such asFigures 1 to 13 As shown, a double-toothed roller crusher based on permanent magnet motor drive includes a crusher housing 1, a main power driving device, a first driving rotary disc 2, a first crushing roller 3, a second driving rotary disc 4, a second crushing roller 5 and an adjusting mechanism 6, wherein the main power driving device is arranged at the side end of the crusher housing 1, a processing cavity is arranged on the inner side of the crusher housing 1, two first driving rotary discs 2 and two second driving rotary discs 4 are respectively arranged, the two first driving rotary discs 2 are coaxially and rotatably arranged on the crusher housing 1, the two second driving rotary discs 4 are coaxially and rotatably arranged on the crusher housing 1, the four adjusting mechanisms 6 are arranged, the two first driving rotary discs 2 and the second driving rotary discs 4 are coaxially and rotatably arranged on the crusher housing 1, the four adjusting mechanisms 6 are arranged, the two first driving rotary discs 2 and the second driving rotary discs 4 are coaxially and rotatably arranged on the crusher housing 1, the An adjusting mechanism 6 is respectively arranged on the driving turntable 2 and the second driving turntable 4, and the main power driving device is respectively connected to the first driving turntable 2 and the second driving turntable 4, the first crushing roller 3 is rotatably arranged in the processing cavity and is located between the first driving turntables 2 on both sides, and the adjusting mechanism 6 on the two first driving turntables 2 controls the distance between the central axis of the first crushing roller 3 and the first driving turntable 2, the second crushing roller 5 is rotatably arranged in the processing cavity and is located between the second driving turntables 4 on both sides, and the adjusting mechanism 6 on the two second driving turntables 4 controls the distance between the central axis of the second crushing roller 5 and the second driving turntable 4.

[0040] The staff can adjust the adjusting mechanism 6 according to different materials and different crushing requirements. When it is necessary to ensure the uniformity of material crushing, the adjusting mechanism 6 is used to adjust the axis of the first crushing roller 3 and the axis of the first driving turntable 2 to be in the same straight line, and the adjusting mechanism 6 is used to adjust the axis of the second crushing roller 5 and the axis of the second driving turntable 4 to be in the same straight line. At this time, the first driving turntable 2 drives the first crushing roller 3 to rotate coaxially, and the second driving turntable 4 drives the second crushing roller 5 to rotate coaxially. The mutual operation of the first crushing roller 3 and the second crushing roller 5 can realize the crushing operation of the material.

[0041] When it is necessary to control and improve the crushing effect of the double-toothed roller crusher, a certain interval is adjusted between the axis of the first crushing roller 3 and the axis of the first driving turntable 2 through the adjusting mechanism 6. The size of the interval is set according to the size of the crushed material. At the same time, the axis of the second crushing roller 5 and the axis of the second driving turntable 4 are in the same straight line. During operation, the first driving turntable 2 drives the first crushing roller 3 to rotate eccentrically, and the second driving turntable 4 drives the second crushing roller 5 to rotate coaxially. The first crushing roller 3 continuously impacts the second crushing roller 5 during continuous eccentric rotation, so that the material passing through the first crushing roller 3 and the second crushing roller 5 can be continuously impacted, thereby improving the crushing efficiency. On this basis, this effect can also be achieved by controlling the first driving turntable 2 to drive the first crushing roller 3 to rotate coaxially and the second driving turntable 4 to drive the second crushing roller 5 to rotate eccentrically through the adjusting mechanism 6.

[0042] When further improving the crushing effect of the double-toothed roll crusher, a certain interval is provided between the axis of the first crushing roll 3 and the axis of the first driving turntable 2 through the adjusting mechanism 6, and a certain interval is provided between the axis of the second crushing roll 5 and the axis of the second driving turntable 4 through the adjusting mechanism 6. The size of the interval is set according to the size of the crushed material. During operation, the first driving turntable 2 drives the first crushing roll 3 to rotate eccentrically, and the second driving turntable 4 drives the second crushing roll 5 to rotate eccentrically, so that the material can be impacted during the rotation and crushing of the first crushing roll 3 and the second crushing roll 5 and thus be crushed.

[0043] In some embodiments, the adjusting mechanism 6 includes a horizontal adjusting screw rod 61, an adjusting slider 62 and an adjusting limit cover 63. A horizontal adjusting screw rod 61 is rotatably provided on each of the first driving turntable 2 and the second driving turntable 4, and an adjusting slider 62 is slidably provided on each of the first driving turntable 2 and the second driving turntable 4. The adjusting sliders 62 at corresponding positions are respectively connected to the first crushing roll 3 and the second crushing roll 5 in a driving manner. A screw sleeve that fits with the horizontal adjusting screw rod 61 is provided on the adjusting slider 62, and an adjusting limit cover 63 is respectively provided at corresponding positions on the first driving turntable 2 and the second driving turntable 4. The user can drive the adjusting slider 62 to slide inside the adjusting limit cover 63 by rotating the horizontal adjusting screw rod 61, so as to adjust the position of the first crushing roll 3 on the first driving turntable 2 or the position of the second crushing roll 5 on the second driving turntable 4.

[0044] In some embodiments, the adjusting mechanism 6 further includes an adjusting bevel gear 64. Adjusting bevel gears 64 are rotatably provided on each of the first driving turntable 2 and the second driving turntable 4. A synchronous gear 611 that meshes with the adjusting bevel gear 64 is provided at the side end of the horizontal adjusting screw rod 61. A corresponding adjusting groove is provided on the adjusting bevel gear 64, and the adjusting groove can be set as an internal hexagonal groove. The user can rotate the adjusting bevel gear 64 with a hexagonal wrench. The adjusting bevel gear 64 drives the synchronous gear 611 to rotate, and the synchronous gear 611 drives the horizontal adjusting screw rod 61 to rotate, so as to realize the adjustment of the first crushing roll 3 and the second crushing roll 5. On this basis, this structure can also prevent the position of the first crushing roll 3 and the second crushing roll 5 from shifting due to the rotation of the horizontal adjusting screw rod 61 when the adjusting mechanism 6 rotates at a high speed.

[0045] In some embodiments, the adjustment limit cover 63 is provided with an adjustment scale 631, and the adjustment slider 62 is provided with a notch corresponding to the adjustment scale 631 on the adjustment limit cover 63. The user can judge the current axis deviation position of the first crushing roller 3 and the second crushing roller 5 by observing the position of the adjustment scale 631 and the notch, so as to quickly adjust the position of the first crushing roller 3 and the second crushing roller 5 according to process requirements or material crushing requirements.

[0046] like Figure 8 and Figure 9 As shown, in some embodiments, a discharge mechanism 7 is provided on the upper side of the crusher housing 1, and the discharge mechanism 7 includes a discharge drive unit 71, a discharge swing rod 72, a discharge control panel 73 and a discharge limit sleeve 74. The discharge drive unit 71 is provided at the side end of the crusher housing 1, and the discharge swing rod 72 is rotatably provided on the crusher housing 1. The discharge drive unit 71 is transmission-connected to the discharge swing rod 72, and the discharge drive unit 71 drives the discharge swing rod 72. The discharge control plate 73 is in the processing cavity, and the discharge swing rod 72 is provided with a first linkage rod 721, which is hinged to the side end of the discharge control plate 73. The discharge limit sleeve 74 is rotatably arranged on the inner side wall of the crusher housing 1, and the upper end surface of the discharge control plate 73 is provided with a discharge limit slide bar 731, which is slidably fitted in the discharge limit slide bar 731. When the material is in the crusher housing 1, the material discharging swing rod 72 is driven to swing back and forth on the crusher housing 1 through the discharging drive unit 71. When the discharging swing rod 72 swings to the lower side, it drives the discharging control plate 73 to move relatively horizontally to the upper ends of the first crushing roller 3 and the second crushing roller 5. At this time, the material entering the crusher housing 1 is blocked by the discharging control plate 73, reducing the amount of material input and preventing the material from being blocked between the first crushing roller 3 and the second crushing roller 5 due to excessive material. When the discharging swing rod 72 swings to the upper side, it drives the discharging control plate 73 to be in a relatively vertical state. At this time, the material will smoothly enter between the first crushing roller 3 and the second crushing roller 5 for crushing. On this basis, the discharging swing rod 72 continues to swing and drives the discharging control plate 73 to be in a relatively horizontal state, while pressing down the material between the first crushing roller 3 and the second crushing roller 5, thereby promoting the crushing of the material between the first crushing roller 3 and the second crushing roller 5 and improving the crushing efficiency.

[0047] In some embodiments, the feeding driving unit 71 includes a feeding driving mounting arm 711 and a feeding driving connecting rod 712. The feeding driving mounting arm 711 is drivingly connected to the first driving turntable 2. A second linkage rod 722 is provided on the feeding swing rod 72. One end of the feeding driving connecting rod 712 is hinged to the feeding driving mounting arm 711, and the other end of the feeding driving connecting rod 712 is hinged to the second linkage rod 722. In this way, when the first driving turntable 2 rotates, the power can drive the feeding driving mounting arm 711 to operate synchronously. The feeding driving mounting arm 711 drives the feeding driving connecting rod 712 to operate, the feeding driving connecting rod 712 drives the second linkage rod 722 to operate, and then the second linkage rod 722 drives the feeding swing rod 72 to swing reciprocally. Therefore, it can be ensured that when the first crushing roller 3 and the second crushing roller 5 are damaged and operate, the feeding mechanism 7 is driven synchronously. The faster the operating speeds of the first crushing roller 3 and the second crushing roller 5 are, the higher the crushing efficiency is, and at the same time, the feeding speed of the feeding mechanism 7 also increases synchronously.

[0048] In the above structure, the feeding driving mounting arm 711 can also be drivingly connected to the second driving turntable 4. Through the second driving turntable 4, the feeding driving mounting arm 711, the feeding driving connecting rod 712, the second linkage rod 722 and the feeding swing rod 72 can be driven to operate synchronously.

[0049] In some embodiments, the feeding driving unit 71 further includes a feeding planetary reducer 713. The feeding planetary reducer 713 is arranged on the outer side wall of the crusher housing 1. The first driving turntable 2 and / or the second driving turntable 4 is drivingly connected to the input end of the feeding planetary reducer 713. The feeding driving mounting arm 711 is installed at the output end of the feeding planetary reducer 713. By providing the feeding planetary reducer 713, the rotational torque of the feeding driving mounting arm 711 can be increased, thereby improving the operating stability of the equipment.

[0050] In some embodiments, two feeding limiting sleeves 74 are provided. The two feeding limiting sleeves 74 are arranged on the inner side wall of the crusher housing 1 in a side-by-side manner. Two feeding limiting sliding rods 731 are provided on the upper end face of the feeding control plate 73 in a side-by-side manner. The two feeding limiting sliding rods 731 are respectively in sliding fit with the feeding limiting sleeves 74 on both sides. Two first linkage rods 721 are provided. The two first linkage rods 721 are arranged in parallel with each other. The two first linkage rods 721 are respectively hinged to both sides of the feeding control plate 73, thereby improving the operating stability of the equipment.

[0051] In some embodiments, the main power driving device includes a permanent magnet motor 81, a coupler 82, and a driving speed reducer 83. The output end of the permanent magnet motor 81 is drivingly connected to the input end of the driving speed reducer 83. One end of the coupler 82 is drivingly connected to the output end of the driving speed reducer 83, and the other end is drivingly connected to the first driving turntable 2 or the second driving turntable 4.

[0052] In some embodiments, the processing cavity includes a feeding cavity 91 and a crushing cavity 92. The feeding cavity 91 is located above the crushing cavity 92. The discharging mechanism 7 is located at the feeding cavity 91. The first crushing roller 3 and the second crushing roller 5 are located in the crushing cavity 92.

[0053] Optionally, in order to further prevent the first crushing roller 3 and the second crushing roller 5 from shifting in position during high-speed operation, a through turntable sliding notch 621 is provided inside the first driving turntable 2 and the second driving turntable 4. The adjusting slider 62 is slidably arranged in the turntable sliding notch 621. Two turntable hydraulic cavities 622 are respectively provided on the first driving turntable 2 and the second driving turntable 4. The two turntable hydraulic cavities 622 are respectively communicated with both sides of the turntable sliding notch 621. Turntable hydraulic push rods 623 are respectively slidably arranged in the two turntable hydraulic cavities 622 on both sides. The adjacent ends of the two turntable hydraulic push rods 623 on both sides are respectively in contact with the adjusting slider 62. A turntable communication pipeline 624 is provided between the two turntable hydraulic cavities 622. The turntable communication pipeline 624 communicates the two turntable hydraulic cavities 622. A control valve 625 is provided on the turntable communication pipeline 624. The control valve 625 controls the on-off state of the turntable communication pipeline 624. Hydraulic oil is injected into the turntable hydraulic cavities 622 and the turntable communication pipeline 624. The hydraulic oil can flow between the two turntable hydraulic cavities 622 through the turntable communication pipeline 624.

[0054] As Figure 10 and Figure 11 shown, when it is necessary to adjust the position of the adjusting slider 62, the control valve 625 is opened. At this time, the adjusting slider 62 slides left and right in the turntable sliding notch 621. When the adjusting slider 62 slides to the left, it drives the left turntable hydraulic push rod 623 to move to the left, and at the same time compresses the hydraulic oil in the left turntable hydraulic cavity 622 so that it flows through the turntable communication pipeline 624 to the right turntable hydraulic cavity 622. The increased hydraulic oil in the turntable hydraulic cavity 622 pushes the right turntable hydraulic push rod 623 to move to the left to tightly press the left side of the adjusting slider 62;

[0055] When the position adjustment of the adjusting slider 62 is completed, the control valve 625 is closed. At this time, the hydraulic oil in the two turntable hydraulic cavities 622 is in a constant state and cannot flow. Therefore, the two turntable hydraulic push rods 623 are in fixed positions to restrict the adjusting slider 62 from moving left and right.

[0056] On this basis, the control valve 625 further includes a control sliding block 6251 and a control return spring 6252. A control slide groove 6241 is arranged in the middle of the turntable connecting pipeline 624. The turntable connecting pipeline 624 is respectively connected with the upper side of the control slide groove 6241. The control sliding block 6251 is slidably embedded in the control slide groove 6241. The control return spring 6252 is installed in the control slide groove 6241 and contacts the control sliding block 6251. The control return spring 6252 pushes the control sliding block 6251 to move downward so that the turntable connecting pipeline 624 and the control slide groove 6241 are in a passage state.

[0057] like Figure 13 As shown, when the double-toothed roller crusher stops running, the control return spring 6252 generates a thrust to move the control sliding block 6251 downward to avoid the connecting position between the turntable connecting pipeline 624 and the control slide groove 6241. At this time, the staff can adjust the position of the adjusting slider 62, and the hydraulic oil will enter the turntable hydraulic cavity 622 on both sides through the turntable connecting pipeline 624 and the control slide groove 6241. When the double-toothed roller crusher is running, the first driving turntable 2 and the second driving turntable 4 run at high speed to generate centrifugal force to make the control sliding block 6251 slide outward and block the connecting position between the turntable connecting pipeline 624 and the control slide groove 6241. At this time, the hydraulic oil cannot pass through the control slide groove 6241 to ensure that the adjusting slider 62 will not be displaced during the operation of the equipment.

[0058] like Figure 13 As shown, further, a counterweight is provided on the control sliding block 6251, and the counterweight enables the first driving turntable 2 and the second driving turntable 4 to quickly drive the control sliding block 6251 to move when rotating, thereby ensuring the operating stability of the equipment.

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the protection scope of the claims of the present invention.
