DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] In order to better understand the purpose, structure and function of the present invention, the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Embodiment 1

[0034] As Figures 1-6An efficient crusher shown in the figure includes: a crushing box 1, a crushing mechanism 2, an adjusting mechanism 3, and a driving mechanism 4. The crushing mechanism 2 is respectively connected to the adjusting mechanism 3 and the driving mechanism 4.

[0035] Among them, a feed inlet 1-1 is provided at the top of the crushing box 1, the crushing mechanism 2 is provided inside, and a discharge outlet 1-2 is provided at the bottom. To facilitate feeding, the cross-section of the feed inlet 1-1 is trapezoidal with a wider top and a narrower bottom to reduce the probability of material blockage at the feed inlet 1-1. To facilitate support, support columns 6 are provided at the bottom of the crushing box 1. Specifically, support columns 6 are arranged at the four corners of the bottom of the crushing box 1, and the adjacent support columns 6 can be connected by strengthening columns to increase the stability of the support.

[0036] The crushing mechanism 2 is used to crush materials. To facilitate the smooth delivery of materials from the feed inlet 1-1 to the crushing mechanism 2 for crushing, the crushing mechanism 2 is located directly below the feed inlet 1-1 and corresponds to the feed inlet 1-1. The crushing mechanism 2 includes two spike rollers 2-1 arranged in parallel on a horizontal plane; as Figure 6 shown, the spike roller 2-1 includes a roller shaft 2-2 and a number of roller knives 2-3 provided on the outer wall of the roller shaft 2-2. The number of the roller knives 2-3 is arranged along the axial direction of the roller shaft 2-2, and the roller knives 2-3 on the two spike rollers 2-1 are staggered to ensure the uniformity and integrity of material crushing.

[0037] The spike roller 2-1 is connected to the adjusting mechanism 3. The adjusting mechanism 3 is used to adjust the distance between the two spike rollers 2-1. On the one hand, it adjusts the particle size of the crushed material. On the other hand, after crushing is completed, it adjusts the distance between the roller knives 2-3 on the two spike rollers 2-1 and the roller shaft 2-2, and uses the roller knives 2-3 to mechanically scrape off the materials attached to the other roller shaft 2-2, and then regularly cooperates with cleaning and other means to complete the cleaning of the crushing box 1.

[0038] To provide space for the roller 2-2 to move, sliding grooves 1-3 are provided on two opposite side walls of the crushing box 1; the side walls with the sliding grooves 1-3 are perpendicular to the axis of the roller 2-2; both ends of the roller 2-2 of the spike roller 2-1 are sleeved with sliders 2-4, and the sliders 2-4 are located inside the sliding grooves 1-3 and are slidably connected to the sliding grooves 1-3. The sliding grooves 1-3 provide space for the spike roller 2-1 to move, and the ends of the sliders 2-4 are connected to the adjusting mechanism 3. When the adjusting mechanism 3 works, it drives the sliders 2-4 to move in the sliding grooves 1-3 to adjust the distance between the two spike rollers 2-1. And the sliders 2-4 are rotatably connected to the roller 2-2 to ensure that the roller 2-2 can rotate, and the two spike rollers 2-1 interact to crush the material; specifically, rolling bearings are provided inside the sliders 2-4. The outer ring of the bearing is in small clearance fit with the slider 2-4, and the inner ring is in small clearance fit or interference fit with the roller 2-2 of the spike roller 2-1. Since the inner and outer rings of the bearing can rotate relative to each other, the spike roller 2-1 and the slider 2-4 rotate relative to each other.

[0039] Further, the adjusting mechanism 3 includes a hydraulic cylinder. The output end of the hydraulic cylinder is connected to the slider 2-4, and the fixed end is fixedly connected to the crushing box 1; in this embodiment, a fixing plate 1-4 is provided on the crushing box 1 in the middle of the sliding groove 1-3, and the fixing plate 1-4 is fixedly connected to the fixed end of the hydraulic cylinder. The connection between the hydraulic cylinder and the fixing plate 1-4 and the slider 2-4 both adopts bolt connection. Of course, the structural form of the adjusting mechanism 3 is not limited to the hydraulic cylinder. Any structure or device that can drive reciprocating motion in the sliding groove 1-3 is acceptable, such as a cylinder.

[0040] The spike roller 2-1 is connected to the driving mechanism 4, and the driving mechanism 4 is used to drive the two spike rollers 2-1 to rotate relatively. The driving mechanism 4 is installed on the side wall of the crushing box 1 provided with the sliding groove 1-3. In this embodiment, the driving mechanism 4 includes a motor 4-1, a tensioning assembly 4-3 and a transmission assembly 4-4; the motor 4-1 is installed on the side wall of the crushing box 1 through a motor 4-1 seat, and its output shaft is connected to one of the spike rollers 2-1 and the tensioning assembly 4-3 through a belt 4-2. The tensioning assembly 4-3 is used to adjust the tightness of the belt 4-2 when the position of the spike roller 2-1 changes to ensure the normal rotation of the spike roller 2-1.

[0041] As Figure 5As shown, the tensioning assembly 4-3 includes a fixing frame 4-31, a movable block 4-32, and an adjusting screw 4-33. The fixing frame 4-31 is in a "U" shape and is horizontally arranged. Its open end is bolted to the side wall of the crushing box 1, and its closed end is provided with a threaded hole engaged with the adjusting screw 4-33. The movable block 4-32 is slidably arranged left and right inside. The adjusting screw 4-33 passes through the threaded hole and is threadedly connected to the movable block 4-32. Among them, grooves 4-36 are provided at the upper and lower ends of the movable block 4-32, and the grooves 4-36 are slidably connected to the upper and lower parts of the fixing frame 4-31. During use, turn the adjusting screw 4-33, and under the threaded fit with the movable block 4-32, drive the movable block 4-32 to slide left and right. A connecting shaft 4-34 perpendicular to the axis of the adjusting screw 4-33 is provided in the middle of the movable block 4-32. The end of the connecting shaft 4-34 is coaxially rotatably connected to a tensioning wheel 4-35, and the tensioning wheel 4-35 is connected to the belt 4-2. The change in the position of the movable block 4-32 drives the change in the positions of the connecting shaft 4-34 and the tensioning wheel 4-35, so that the belt 4-2 wound around the tensioning wheel 4-35, the motor 4-1, and the threshing roller 2-1 is tensioned, so as to transmit the rotation of the motor 4-1 to the threshing roller 2-1.

[0042] The transmission assemblies 4-4 are detachably installed at the ends of the two threshing rollers 2-1. The transmission assemblies 4-4 are used to make the two threshing rollers 2-1 rotate towards each other to achieve the purpose of crushing. The threshing rollers 2-1 are detachably connected to the transmission assemblies 4-4, which is convenient for replacing and installing transmission assemblies 4-4 of different sizes after the distance between the two threshing rollers 2-1 changes, so as to adapt to the distance between the two threshing rollers 2-1. The transmission assemblies 4-4 are located outside the belt 4-2, which is convenient for disassembly and assembly. In this embodiment, the transmission assemblies 4-4 include a gear one 4-41 and a gear two 4-42 respectively coaxially connected to the ends of the two threshing rollers 2-1. The gear one 4-41 meshes with the gear two 4-42. The connection between the gear and the roller shaft 2-2 is through a key connection, which is a common connection method in the mechanical field and will not be specifically described here.

[0043] To facilitate the smooth discharge of the crushed material from the discharge port 1-2, the discharge port 1-2 is located directly below the crushing mechanism 2 and corresponds to the discharge port 1-2. In addition, two guide plates 5 are provided inside the crushing box 1 in an inclined and symmetric manner. The guide plates 5 are located below the crushing mechanism 2 and extend along the axial direction of the threshing roller 2-1. Their upper ends are connected to the inner wall of the crushing box 1, and their lower ends extend towards the middle of the crusher, and the lower ends correspond to the discharge port 1-2. The function of the guide plates 5 is to block and guide the crushed material so that it can be discharged from the discharge port 1-2.

[0044] Embodiment 2

[0045] The structures of this embodiment that are the same as those of Embodiment 1 have the same names, functions, and reference numerals, and will not be described in detail here.

[0046] As Figures 7-9 shown, a secondary crushing mechanism is provided below the crushing mechanism 2. The secondary crushing mechanism is connected to the driving mechanism 4 and is used to further crush the materials crushed by the crushing mechanism 2 so that the particle size of the material finished product meets the requirements.

[0047] In this embodiment, the structure of the secondary crushing mechanism is the same as that of the crushing mechanism 2, and also includes two spike rollers 2-1 arranged in parallel on a horizontal plane. Moreover, the extending direction of the spike rollers 2-1 is the same as that of the spike rollers 2-1 of the crushing mechanism 2 and is located directly below the spike rollers 2-1 of the crushing mechanism 2. And the spike rollers 2-1 in this embodiment are also connected to hydraulic cylinders, that is, two chutes 1-3 arranged vertically are provided on the opposite side walls of the crushing box. The inner part of the lower chute 1-3 is slidably matched with the sliders 2-4 on the spike rollers 2-1. The sliders 2-4 are rotationally connected to the spike rollers 2-1, and the two spike rollers 2-1 are connected by meshing gears. In this embodiment, the guide plate 5 below the crushing mechanism is used to guide the crushed materials to the secondary crushing mechanism, and a guide plate is also provided below the secondary crushing mechanism to block and guide the crushed materials so as to facilitate discharging from the discharge port 1-2. The specific structures and connection relationships of the spike rollers, hydraulic cylinders, and guide plates are the same as those of Embodiment 1 and will not be described repeatedly.

[0048] In a possible implementation manner, a second tensioning wheel is coaxially connected to the connecting shaft 4-34 in Embodiment 1. The second tensioning wheel, the output shaft of the motor 4-1, and one roller shaft 2-2 in this embodiment are connected by a transmission belt 4-5. In another possible implementation manner, a second tensioning assembly is provided on the side wall of the crushing box 1. The structure of the second tensioning assembly is the same as that of the tensioning assembly 4-3 and is located below the tensioning assembly 4-3. The tensioning wheel 4-35 in the second tensioning assembly is connected to the output shaft of the motor 4-1 and one roller shaft 2-2 in this embodiment by a transmission belt 4-5. To avoid interference, the two tensioning wheels 4-35 are staggered. The above two methods can both achieve the purpose of controlling the operation of the crushing mechanism 2 and the secondary crushing mechanism by one motor 4-1, reducing the equipment and operation and maintenance costs, and making the crushing more efficient.
