DETAILED DESCRIPTION

[0022] ​The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] To address the problems mentioned in the background technology, this solution provides a jaw crusher. During operation, material is fed into the jaw crushing structure 3 through the feeding hopper 2 for coarse crushing. The coarsely crushed material then falls sequentially into the first and second double-roll mills 4 and 5 for fine crushing, ultimately achieving the required particle size. During the fine crushing process, if hard or uncrushable objects are encountered, the driven wheel 43 automatically retracts under the action of the compression structure 44, increasing the gap between the driving wheel 42 and the driven wheel 43. This allows the hard or uncrushable objects to fall off, thus protecting the machine from damage.

[0024] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0025] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0026] Example 1

[0027] A jaw roll crusher, such as Figures 1-4 As shown, the machine includes a frame 1 and a working platform 8 fixedly installed next to it, which facilitates operation by the staff. From top to bottom, the frame 1 is fixedly installed with a feeding bin 2, a jaw crusher structure 3, a double roller mill 4, a double roller mill 5, and a material outlet 6.

[0028] Feed hopper 2 is located above the inlet of jaw crusher 3 and is used to feed material into jaw crusher 3. Jaw crusher 3, roller mill 4, and roller mill 5 are sequentially and sealed together by flexible connections 7, forming a closed crushing system. Jaw crusher 3 is existing technology and is mainly used for coarse crushing of materials; roller mill 4 and roller mill 5 are used for further fine crushing of the coarsely crushed material. The flexible connections 7 not only effectively prevent dust leakage but also facilitate the introduction of inert gas for protection during the crushing process, effectively preventing the mixing of outside air and preventing oxidation or spontaneous combustion of the material. Material outlet 6 is fixedly installed below roller mill 5 and is used to discharge the finely crushed material from roller mill 5.

[0029] The roller mill one 4 and the roller mill two are the same in structure, and each includes a motor 41, a driving wheel 42 and a driven wheel 43, the motor 41 is used for driving the driving wheel 42 to rotate, and then drives the driven wheel 43 to crush the material, and the rotating shaft 48 of the driven wheel 43 is connected with a tight structure 44 for self-adapting the hardness of the material at both ends.

[0030] The tight structure 44 is horizontally fixedly installed on the rack 1, a side close to the driven wheel 43 is fixedly connected with a hole mounting plate 45, the hole mounting plate 45 is fixedly installed with a horizontal bearing with seat 46, and the rotating shaft 48 of the driven wheel 43 is connected with the tight structure 44 in a mode of penetrating through the horizontal bearing with seat 46 and the hole mounting plate 45. When hard or unbreakable materials are encountered in the crushing process, the tight structure 44 can be correspondingly extruded to retreat, so that the gap between the driving wheel 42 and the driven wheel 43 is increased, and the hard or unbreakable materials fall through the gap.

[0031] In the embodiment, the rack 1 below the hole mounting plate 45 is also fixedly installed with a horizontal limiting rail 47, so that the hole mounting plate 45 can only move horizontally in the radial direction of the driven wheel 43, the tight structure 44 is prevented from being unevenly stressed to cause the driven wheel 43 to deviate, and the machine is prevented from being damaged.

[0032] In the embodiment, the tight structure 44 is in the form of a tight spring, and in other embodiments, the tight structure 44 can also be in other forms such as a hydraulic cylinder, so as to adapt to different application scene requirements.

[0033] Embodiment 2

[0034] The difference between the embodiment and the embodiment 1 is that:

[0035] As shown in Figure 4 The tight structure 44 is not connected with the hole mounting plate 45, but is fixedly connected with the horizontal bearing with seat 46, so that the stability of the driven wheel 43 in the retreat process and the tight structure 44 is further improved, and the safe operation of the device is ensured.

[0036] The above is based on the ideal embodiment of the utility model, but it is obvious to those skilled in the art that such embodiments are provided only in an exemplary manner. Those skilled in the art can think of many changes, changes and alternative ways without departing from the idea and spirit of the utility model. It should be understood that various alternative schemes of the utility model embodiments described herein can be adopted in the process of practicing the utility model. The appended claims aim to define the protection scope of the utility model, and thus cover the module composition, equivalents or alternative schemes within the protection scope of the claims.
