For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The present application provides a toothed roller crusher, referring to Figure 1 The toothed roller crusher includes two groups of toothed roller assemblies 1, each group of toothed roller assemblies 1 includes a driving source 11, a reducer 12, a toothed roller 13 and an energy storage wheel 15, wherein: the power output end of the driving source 11 is connected to the toothed roller 13 through the reducer 12, and the energy storage wheel 15 is mounted on the toothed roller 13.

[0034] During the operation of the toothed roller crusher provided by the present application, the kinetic energy of the driving source 11 is transmitted to the toothed roller 13 through the reducer 12, and the two toothed rollers 13 rotate in opposite directions under the drive of the driving source 11 to crush the material. In this process, the energy storage wheel 15 rotates synchronously with the toothed roller 13, and the energy storage wheel 15 can increase the rotational inertia of the toothed roller 13, so that the toothed roller 13 has a larger angular kinetic energy, and improves the instantaneous impact shear force of the toothed roller on the material; when the hardness or output of the material is large, the collision between the material and the toothed roller 13 can be converted into the kinetic energy of the energy storage wheel 15, and the kinetic energy of the energy storage wheel 15 is transmitted to the toothed roller 13 and converted into crushing energy for crushing the material. The setting of the energy storage wheel 15 enables the crusher to efficiently crush hard materials and alleviates the phenomenon of material blocking in the crusher; in addition, the inertia of the energy storage wheel 15 can make the load of the motor tend to be uniform, thereby reducing the rated power of the motor. The crusher provided in the present application adopts a reducer 12 to transmit power, which can prevent the tooth roller 13 and the energy storage wheel 15 from continuing to rotate under inertia after shutdown, thereby improving the safety of the crusher during use.

[0035] In this embodiment, each set of gear roller assembly 1 further includes a hydraulic coupler, which is connected between the driving source 11 and the reducer 12. Specifically, the driving source 11 is a motor, the output shaft of the motor is connected to the power input end of the reducer 12 through the hydraulic coupler, and the power output end of the reducer 12 is connected to the gear roller 13 through a coupling. The hydraulic coupler has excellent starting performance and overload protection performance, can eliminate impact and vibration, and improve the service life of the motor.

[0036] In this embodiment, the driving sources 11 in the two sets of gear roller assemblies 1 are arranged side by side, and the reducers 12 in the two sets of gear roller assemblies 1 are arranged side by side. The above arrangement can reduce the overall length of the crusher, thereby reducing the footprint of the crusher. Based on the above structure, the driving sources 11 and the reducers 12 in the two sets of gear roller assemblies 1 can be arranged in a protective box (not shown in the figure), and the power structure is protected by the protective box, while making the overall device look simple and beautiful.

[0037] Reference Figure 1 and Figure 3 The toothed roller crusher also includes a crushing box 2 and a base 3, wherein:

[0038] The tooth roller 13 is provided with a crushing part, which includes a plurality of crushing teeth; the crushing part is arranged in the crushing box 2, and one end of the tooth roller 13 passes through the crushing box 2 and is connected to the reducer 12;

[0039] The driving source 11 , the speed reducer 12 and the crushing box 2 are all mounted on the base 3 .

[0040] During the operation of the toothed roller crusher, the material enters between the crushing parts of the two toothed rollers 13 from the opening of the crushing box 2, and is crushed by the crushing teeth on the two toothed rollers 13. The base 3 connects the toothed roller assembly 1 and the crushing box 2 to form a whole, which is convenient for disassembly, assembly and transfer of the crusher.

[0041] On the basis of the above structure, the energy storage wheels 15 in the two sets of gear roller assemblies 1 are respectively arranged at opposite ends of the crushing box 2. In this embodiment, one energy storage wheel 15 is installed on each gear roller 13, and the energy storage wheels 15 on the two gear rollers 13 are respectively arranged at opposite ends of the crushing box 2. In the above structure, the two energy storage wheels 15 respectively input power at both ends of the crushing part of the gear roller 13, so that the power transmission is more stable.

[0042] Continue to refer to Figure 1 Each set of toothed roller assembly 1 also includes two support seats 14, which are respectively arranged at opposite ends of the crushing box 2, and the two ends of the toothed roller 13 are respectively passed through the crushing box 2 and connected to the two support seats 14; the energy storage wheel 15 is arranged between one of the support seats 14 and the crushing box 2.

[0043] In the above structure, the support seat 14 is specifically a bearing seat, and the support seat 14 is used to support the two ends of the toothed roller 13 to improve the stability of the toothed roller 13 during rotation. The two ends of the energy storage wheel 15 are limited by the support seat 14 and the crushing box 2 respectively, which alleviates the phenomenon that the energy storage wheel 15 rotates unsteadily due to the large rotational inertia of the energy storage wheel 15. The distance between the support seat 14 and the crushing box 2 is 1.5 to 3 times the thickness of the energy storage wheel 15. This setting can reduce the overall length of the crusher and make the structure of the device more compact. On the other hand, it can improve the stability of the energy storage wheel 15 during rotation, thereby alleviating the vibration of the toothed roller 13.

[0044] Reference Figure 2 The base 3 is a hollow structure. Specifically, the base 3 is made of profiles and plates by welding or screwing. The base 3 has an inner cavity 31, which can effectively eliminate the vibration and noise of the crusher, so that the crusher has the advantages of stable operation and low noise. Hoisting holes for hoisting are also provided on opposite sides of the base 3 to facilitate the transfer of the crusher.

[0045] Reference Figure 3 A wear-resistant plate 21 is provided on the inner wall of the crushing box 2. The provision of the wear-resistant plate 21 can alleviate the wear of the crushing box 2 and prevent the crushing box 2 from being damaged by the friction and impact of the material. In this embodiment, the wear-resistant plate 21 can be detachably fixed to the inner wall of the crushing box 2 by fasteners such as bolts, so as to facilitate the replacement of the wear-resistant plate 21.

[0046] Reference Figure 4 The toothed roller 13 includes a transmission shaft 131, a mounting sleeve 132 and a plurality of crushing blocks 133, wherein:

[0047] The mounting sleeve 132 is sleeved on the transmission shaft 131 ; the mounting sleeve 132 is provided with a plurality of mounting planes distributed along the circumferential direction, and the plurality of mounting planes correspond to the plurality of crushing blocks 133 one by one, and the crushing blocks 133 are mounted on the corresponding mounting planes.

[0048] In this embodiment, the cross-sectional outer contour of the mounting sleeve 132 is polygonal, and each side of the polygon corresponds to a mounting plane. The provision of the mounting plane increases the contact area between the mounting sleeve 132 and the crushing block 133, thereby improving the reliability of the connection between the mounting sleeve 132 and the crushing block 133. A limiting protrusion 1333 is provided on the crushing block 133, and a limiting groove 1321 is provided on the mounting plane. The limiting protrusion 1333 is inserted into the corresponding limiting groove 1321; through the plug-in connection method, the connection strength between the crushing block 133 and the mounting sleeve 132 is further improved.

[0049] Since the crushing teeth on the toothed roller 13 are vulnerable parts, the present application detachably mounts the crushing block 133 with the crushing teeth on the transmission shaft 131; when a certain crushing block 133 is damaged, only the damaged crushing block 133 needs to be replaced, without replacing the entire toothed roller 13, thereby reducing maintenance costs and maintenance difficulties. The mounting sleeve 132 serves as an intermediate connecting piece, which reduces the processing difficulty of the transmission shaft 131, and when the transmission shaft 131 is damaged, there is no need to replace the mounting sleeve 132, further reducing maintenance costs.

[0050] When assembling the toothed roller 13, first, put the mounting sleeve 132 on the transmission shaft 131, and fix the mounting sleeve 132 on the transmission shaft 131 by fasteners such as keys, nuts, and bolts; then, insert the limiting protrusion 1333 on each crushing block 133 into the corresponding limiting groove 1321, and install the crushing block 133 on the corresponding installation plane by fasteners, and the assembly of the toothed roller 13 is completed.

[0051] On the basis of the above structure, the crushing block 133 is provided with a first crushing tooth 1331 and a second crushing tooth 1332 , and the tooth height of the first crushing tooth 1331 and the tooth height of the second crushing tooth 1332 are not equal.

[0052] Figure 4 In the illustrated embodiment, the crushing block 133 is provided with a plurality of (specifically two) first crushing teeth 1331 and a plurality of (specifically two) second crushing teeth 1332, and the first crushing teeth 1331 and the second crushing teeth 1332 are alternately distributed; the tooth height H1 of the first crushing teeth 1331 is greater than the tooth height H2 of the second crushing teeth 1332. When the tooth roller 13 is assembled, the first crushing teeth 1331 and the second crushing teeth 1332 on the tooth roller 13 are alternately distributed along the circumference of the tooth roller 13, and a concave area is formed between any two adjacent first crushing teeth 1331. The alternatingly long and short crushing teeth can better pull the material downward, alleviate the phenomenon of material blocking, and thus improve the crushing effect of the material.

[0053] In summary, in the toothed roller crusher provided by the present application, energy storage and release can be achieved through the energy storage wheel 15, the instantaneous impact shear force of the crusher is greatly improved, and materials with higher hardness can be crushed to alleviate the phenomenon of material blocking. At the same time, the inertia of the energy storage wheel 15 can make the load of the motor tend to be uniform, thereby reducing the rated power of the motor; the power structure of the two toothed roller assemblies 1 is arranged on the same side, which reduces the overall footprint of the equipment and meets the crushing needs under the condition of small site space; the toothed roller 13 is a split structure, which reduces the difficulty and cost of maintenance, and the circumferential direction of the toothed roller 13 is alternately provided with crushing teeth of different lengths, which can improve the crushing effect of the material; a detachable wear-resistant plate 21 is arranged in the crushing box 2, which can improve the service life of the crushing box 2; the base 3 with a hollow structure can well eliminate vibration and noise, and improve the stability of the equipment operation. Through the above structure, the toothed roller crusher provided by the present application has the advantages of high crushing efficiency, stable operation, low noise, low maintenance cost, and compact structure.
