Detailed Implementation

[0028] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0030] like Figures 1 to 6 As shown, a double-layer crusher uses an upper crushing roller assembly, which includes an upper box assembly 30, an upper fixed roller 4, an upper moving roller 5, an upper fixed roller control motor 31, an upper moving roller control motor 32, and an upper moving roller adjustment frame 33.

[0031] The upper box assembly 30 is located below the feed chamber 2 of the double-layer dispersing machine 1;

[0032] The upper fixed roller 4 and the upper movable roller 5 are arranged side by side in the upper box assembly 30;

[0033] The upper fixed roller control motor 31, the upper moving roller control motor 32 and the upper moving roller adjustment frame 33 are located outside the upper box assembly 30;

[0034] One end of the upper fixed roller 4 is connected to the power output end of the upper fixed roller control motor 31;

[0035] One end of the upper moving roller 5 is connected to the upper moving roller adjustment frame 33, and the other end of the upper moving roller 5 is connected to the power output end of the upper moving roller control motor 32 via another upper moving roller adjustment frame 33.

[0036] The purpose of this design is to adjust the distance between the upper fixed roller and the upper moving roller by setting an upper crushing roller assembly containing an upper fixed roller and an upper moving roller inside the double-layer crusher, thereby meeting the processing of raw materials of different sizes and completing coarse crushing.

[0037] It should be noted that when adjusting the size, the upper moving roller is usually adjusted by the upper moving roller adjustment frame, so that the upper moving roller can move horizontally.

[0038] Meanwhile, in this embodiment, the upper box assembly 30 is provided with an upper fixed roller connection hole and an upper movable roller connection hole, and the upper movable roller 5 can move horizontally within the upper movable roller connection hole.

[0039] The upper fixed roller connection hole includes a first sealing plate 34 and a first heat-resistant sealing ring 35. The first heat-resistant sealing ring 35 covers the first sealing plate 34. The upper fixed roller 4 can pass through the through hole on the first sealing plate 34. The upper moving roller connection hole includes a second sealing plate 38 and a second heat-resistant sealing ring 36. The second heat-resistant sealing ring 36 covers the second sealing plate 38. The second heat-resistant sealing ring 36 is provided with a waist-shaped hole 37. The upper moving roller 5 can pass through the waist-shaped hole 37.

[0040] The purpose of this design is to reduce heat conduction to the left and right transmission devices by setting a heat-resistant sealing ring, thereby effectively reducing the heat transferred to the bearing housing.

[0041] In this embodiment, both the upper fixed roller 4 and the upper moving roller 5 include a first main shaft 39, a first positioning sleeve 41 and a first adjusting ring 42. The first main shaft 39 is wrapped with a first crushing tooth group, and the two ends of the first main shaft 39 are connected to the first positioning sleeve 41 via the first shaft end baffle 40.

[0042] The first positioning sleeve 41 is connected to the upper fixed roller control motor 31 or the upper moving roller control motor 32;

[0043] The first adjusting ring 42 wraps around the outer periphery of the first main shaft 39 and is located at the edge of the first crushing cutter tooth group.

[0044] The first set of crushing blades includes short blades 43 and long blades 44. The short blades 43 have six teeth, and the long blades 44 have two teeth. The tooth length of the long blades 44 is greater than the tooth length of the short blades 43. The long blades 44 and short blades 43 are arranged alternately.

[0045] The purpose of this design is that, under normal circumstances, the upper fixed roller and the upper moving roller are crushing rollers with the same structure, only the upper fixed roller and the upper moving roller are different based on the connected motor.

[0046] Meanwhile, both stages of crushing rollers use independent drives, so a failure in the drive of either roller will not affect normal production in a short period of time.

[0047] Furthermore, by setting up staggered short and long blades to form a staggered biting structure, the problem of large pieces of material not being able to be bitten in properly is effectively solved.

[0048] It should be noted that in actual use, the short cutting tooth has a disc-shaped center and cutting teeth on the outer periphery of the disc-shaped center, so the diameter of the entire structure can be 420mm. The long cutting tooth has a disc-shaped center and cutting teeth on the outer periphery of the disc-shaped center, so the diameter of the entire structure can be 650mm.

[0049] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
