To this end, the applicant wishes to devise a crusher capable of improving the crushing effect on hard materials such as stones.

During the rotation of the rotor 2, a shearing force similar to that seen in shearing the objects is formed between the rotor 2 and the outer spiral 21 of the stator 1, which shearing force is capable of shearing the hard material entering between them.
For the stator 1 and the rotor 2, a channel is formed between the outer spiral 22 of the rotor 2, a channel is formed between the inner spiral 11 of the stator 1, when the rotor 2 rotates, the hard material is crushed by extrusion between the channel of the rotor 2 and the inner spiral 11 of the stator 1, and the hard material is crushed by extrusion between the channel of the stator 1 and the outer spiral 21 of the rotor 2.
In this embodiment, the technical principle of driving the rotor 2 to rotate by the driving mechanism is the prior art, and details thereof are not described herein. The related structures of the bottom shell, the top cover, the feeding hopper and the like can be referred to the attached drawings disclosed in CN 217093808U.
In this embodiment, the reason why the crushing effect is better than that of the prior art screw crusher is that: on prior art's basis, increased the inside broken mode to the stereoplasm material of rotor 2, multiple broken mode combines together, can increase the crushing effect to the stereoplasm material, is favorable to the plastic of material.
By adding the first longitudinal grooves 22 to the outer spiral 21 of the rotor 2 and/or the second longitudinal grooves 12 to the outer spiral 21 of the stator 1, a part of the hard material entering through the hopper enters the first longitudinal grooves 22 and the second longitudinal grooves 12, the hard material of larger size is caught in the first longitudinal grooves 22 and the second longitudinal grooves 12 to be fixed, and the hard material of smaller size is further moved down to a proper position to be caught. The portion of the hard material stuck in the first longitudinal groove 22 of the rotor 2 rotates with the rotor 2, and during the rotation, the portion of the hard material collides with the inner spiral 11 of the stator 1, the outer wall of the stator 1, and the portion of the hard material stuck in the second longitudinal groove 12 of the stator 1; similarly, when the rotor 2 rotates, the inner spiral 11 of the rotor 2, the outer wall of the rotor 2 and the portion of the hard material caught in the first longitudinal groove 22 of the rotor 2 may collide with the portion of the hard material fixed in the second longitudinal groove 12 of the stator 1. After the hard material jammed in the first and second longitudinal grooves 22 and 12 is impacted, a part of the crushed hard material may move further downward in the first and second longitudinal grooves 22 and 12, and the downward moving hard material may be jammed again due to the decreasing widths of the first and second longitudinal grooves 22 and 12, and the above impact process may be repeated; meanwhile, a small part of hard materials can rotate along with the rotation of the rotor 2, so that the hard materials are crushed by the shearing force and the extrusion force in the prior art; in addition, there is a portion of the hard material entering the crushing chamber that is carried into the longitudinal grooves of the rotor 2 or stator 1 by the rotation of the rotor 2 and is impacted.
Through the through holes 22 communicated with the inner space 201 of the rotor 2 are arranged on the outer wall of the rotor 2, part of small materials crushed in the crushing cavity can enter the upper surface of the inner spiral 23 in the inner space 201 of the rotor 2 through the through holes 22, and the part of small materials in the rotor 2 can be bumpy and crushed due to the fact that the inner spiral 23 rotates along with the inner spiral 23 and collide with the inner spiral 23; meanwhile, as part of small materials in the crushing cavity enter the rotor 2, the internal space 201 of the rotor 2 is fully utilized, so that part of small materials can be prevented from being excessively crushed in the crushing cavity, powder materials are reduced, and the fineness modulus is improved; and because the small material enters the inner space 201 of the rotor 2, namely the crushing space outside part of the rotor 2 is emptied, more material can enter the crushing cavity, and the crushing amount per unit time is increased.
Therefore, the hard material entering the space between the rotor 2 and the stator 1 is subjected to shearing force, extrusion force and impact force, and is impacted and bumped in the rotor 2, and finally the crushing effect of the hard material is improved.
In order to improve the impact effect on the hard materials, the depths of the first longitudinal grooves 22 arranged on the outer spiral 21 of the rotor 2 and the second longitudinal grooves 12 arranged on the inner spiral 11 of the stator 1 are both satisfied: gradually becomes shallow from top to bottom; the width satisfies: and gradually become larger from top to bottom. Therefore, larger hard materials can be impacted at the upper part, and the hard materials which are impacted to be smaller can be further impacted at the next level or the next position, so that the hard materials can be impacted for multiple times in the longitudinal groove, and the impact effect is improved.
In this example, the first longitudinal grooves 22 provided on the outer spiral 21 of the rotor 2 and/or the second longitudinal grooves 12 provided on the inner spiral 11 of the stator 1 are vertically or obliquely arranged. When the first longitudinal groove 22 and the second longitudinal groove 12 are vertically arranged, the hard material can fall down by the gravity of the hard material after being crushed and is further clamped; when the first longitudinal grooves 22 and the second longitudinal grooves 12 are obliquely arranged, the hard materials rotating with the rotor 2 in the crushing cavity can enter the longitudinal grooves more quickly.
In this embodiment, the number of the first longitudinal grooves 22 provided in the outer spiral 21 of the rotor 2 and/or the second longitudinal grooves 12 provided in the inner spiral 11 of the stator 1 is plural. The greater the number of first longitudinal grooves 22 and second longitudinal grooves 12, the more hard clinker can be stuck and, correspondingly, the more hard material can be hit.
In order to improve the impact effect on the hard material, the inner spiral surface provided in the inner space 201 of the rotor 2 is provided to be non-planar. In the embodiment, the inner spiral surface is arranged in a corrugated shape or a triangular shape, so that the material is bumpy in the rotating process and bumpy and crushed with the corrugated inner spiral surface or the triangular inner spiral surface.
As shown in fig. 4, in the present embodiment, a columnar body 24 is attached to the inner screw provided in the inner space 201 of the rotor 2. The columns 24 are vertically installed on the inner screw 23 so that the material introduced into the inner space 201 of the rotor 2 collides with the columns 24 during the rotation to be crushed.
The inner screw 23 arranged in the inner space 201 of the rotor 2 is provided with a filtering screen with smaller and smaller apertures from top to bottom, the filtering screen forms a vibrating screen when the rotor 2 rotates, the apertures of the screen are sequentially reduced from top to bottom, so that the particle size of the filtered material is smaller and smaller, and finally the particle size of the material discharged through the inner space 201 of the rotor 2 meets the requirement; this part of the material that is not filtered out can then have the opportunity during rotation of the rotor 2 to be discharged again through the through-holes 22 into the outer crushing chamber for crushing.
In the present embodiment, the outer spiral 21 of the rotor 2 may be provided with serrations; and/or serrations may be provided on the inner spiral 11 of the stator 1. Due to the fact that the sawteeth are arranged outside the outer spiral 21 of the rotor 2 and/or the inner spiral 11 of the stator 1, the sawteeth continuously hit or strike the hard materials in the high-speed rotation process of the rotor 2, and the hard materials can be further crushed.
