Description

Technical Field

[0001] This application relates to the field of pulverizer technology, and in particular to a pulverizer. Background Technology

[0002] Existing crushers typically consist of two sets of independently rotating rollers with staggered blades on their surfaces. The crushing and shearing forces generated by the relative rotation of the two rollers break up materials. Because the blades on the two sets of rollers are staggered and relatively close together, during maintenance of one set of rollers, it is easy for that roller to collide with adjacent blades during disassembly, causing unnecessary wear. Therefore, a new type of crusher is proposed. Utility Model Content

[0003] To address the problem that in existing crushers, the blades on the two sets of rollers are staggered and relatively close together, making it easy for the roller to collide with the adjacent blades during disassembly and causing wear when maintenance is required, this application provides a crusher.

[0004] The crusher provided in this application adopts the following technical solution:

[0005] A pulverizer includes a housing with two sets of pulverizing rollers inside. Each pulverizing roller has a rotating shaft fixedly connected to both ends. A slider is rotatably mounted on the surface of each rotating shaft. Slide grooves adapted to the sliders are formed on both sides of the housing, allowing the sliders to move into or out of the slide grooves. Symmetrically arranged fixing frames are fixedly connected to the outer surface of the housing. Motors are fixedly mounted on the surfaces of each fixing frame, and connecting shafts are fixedly connected to the output ends of each motor. When the slider is at the bottom of the slide groove, the rotating shaft and the connecting shaft are aligned, and a connecting mechanism is provided between the rotating shaft and the connecting shaft.

[0006] Preferably, both the slider and the groove are rectangular structures, the slider and the groove form a sliding pair in the vertical direction, and the groove opening is upward.

[0007] Preferably, the connecting mechanism includes a connecting plate, which is configured as a U-shaped structure. The surfaces of the rotating shaft and the connecting shaft are provided with positioning grooves and threaded holes. The two ends of the opening side of the connecting plate can be moved into or out of the positioning grooves. Positioning bolts are inserted into both ends of the connecting plate, and the positioning bolts can be screwed into or out of the threaded holes.

[0008] Preferably, the top of the slide is fitted with a baffle, the baffle creates movement interference to the slider in the vertical direction, the surface of the housing is provided with a fixing groove, and a fixing bolt is inserted into the surface of the baffle, the fixing bolt can be screwed into or out of the fixing groove.

[0009] Preferably, each slider is fixedly connected to a handle on one side of the outer surface of the box.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] When disassembling a set of crushing rollers, this utility model first disconnects the connection mechanism between the crushing roller and the corresponding connecting shaft, and then moves the slider and the crushing roller upward along the slide groove. Since the crushing roller moves along the preset slide groove, it will not bump into surrounding objects during the disassembly process, thereby improving the safety of disassembly and avoiding unnecessary damage.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0019] This application discloses a pulverizer, including a housing 1. Two sets of pulverizing rollers 2 are arranged inside the housing 1. Both ends of the pulverizing rollers 2 are fixedly connected to rotating shafts 10. Slider 9 is rotatably sleeved on the surface of the rotating shafts 10. Slide grooves 8 adapted to the slider 9 are opened on both sides of the housing 1. The slider 9 can move into or out of the slide grooves 8. A symmetrically arranged fixing frame 6 is fixedly connected to the outer surface of the housing 1. A motor 5 is fixedly installed on the surface of the fixing frame 6. A connecting shaft 11 is fixedly connected to the output end of the motor 5. When the slider 9 is located at the bottom of the slide groove 8, the rotating shaft 10 and the connecting shaft 11 are aligned, and a connecting mechanism is provided between the rotating shaft 10 and the connecting shaft 11.

[0020] Furthermore, both the slider 9 and the slide 8 are rectangular structures, forming a sliding pair in the vertical direction, with the slide 8 opening upwards.

[0021] Furthermore, the connecting mechanism includes a connecting plate 12, which is configured as a U-shaped structure. The rotating shaft 10 and the connecting shaft 11 are both provided with positioning grooves 13 and threaded holes 14. The two ends of the opening side of the connecting plate 12 can be moved into or out of the positioning grooves 13. Positioning bolts 15 are inserted into both ends of the connecting plate 12, and the positioning bolts 15 can be screwed into or out of the threaded holes 14.

[0022] Furthermore, each slider 9 is fixedly connected to a handle 16 on one side of the outer surface of the housing 1.

[0023] In this embodiment, by setting the slider 9 to cooperate with the slide groove 8, when it is necessary to disassemble a certain set of crushing rollers 2, firstly, the connection mechanism between the crushing roller 2 and the corresponding connecting shaft 11 of the crushing roller 2 is released. Specifically, the positioning bolts 15 are loosened, and the two ends of the connecting plate 12 are removed from the positioning grooves 13 on the rotating shaft 10 and the connecting shaft 11. Then, the operator can hold the handles 16 on the surface of the slider 9 at both ends of the crushing roller 2 and move the slider 9 and the crushing roller 2 upward along the slide groove 8. Since the crushing roller 2 moves along the preset slide groove 8, it will not bump into surrounding objects during the disassembly process, thereby improving the safety of disassembly and avoiding unnecessary damage.

[0024] It should be noted that when the crushing roller 2 needs to be installed, simply reverse the above steps to reconnect the connecting shaft 11 and the rotating shaft 10. After installation, turn on the power of the motor 5 to drive the connecting shaft 11, the rotating shaft 10 and the crushing roller 2 to rotate, thereby realizing the crushing function of the crushing roller 2.

[0025] In this embodiment, the switch interface of motor 5 is connected to an external power source via a wire. The circuits and related drivers involved are all existing conventional technologies and will not be described in detail here.

[0026] Furthermore, the top of the slide 8 is fitted with the baffle 3, which in turn interferes with the movement of the slider 9 in the vertical direction. The surface of the housing 1 is provided with a fixing groove 7, and the surface of the baffle 3 is fitted with fixing bolts 4, which can be screwed into or out of the fixing groove 7.

[0027] In this embodiment, by setting the baffle 3 to restrict the slider 9 inside the groove 8, the stability of the crushing roller 2 when rotating can be improved, and when it is necessary to disassemble the crushing roller 2, it is only necessary to loosen the fixing bolt 4 and then remove the baffle 3 from the groove 8.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
