The motor 4 may be disposed below or above the tapered roller 1, or at other locations, and is not limited thereto, for the purpose of driving the tapered roller 1 to rotate about its center axis.
When the crushing device works, materials to be crushed are put into a gap between the conical tooth roller 1 and the umbrella tooth roller 2 from the top end of the device. The motor 4 drives the conical tooth roller 1 to rotate, and the material contact surface 3 at the inner side of the conical tooth roller 2 and the material contact surface 3 at the outer side of the conical tooth roller 1 move in opposite directions to generate friction force and impact force on materials, so that the purpose of crushing is achieved.
Further, the bevel gear roller 2 and the bracket are rotatably connected, and the bevel gear roller 2 can move up and down.

The contact surface is the surface contacted with the material to be crushed, and specifically is the outer side surface of the conical toothed roller 1 and the inner side surface of the umbrella-shaped toothed roller 2.
Further, the umbrella-shaped toothed roller 2 is in a hollow frustum shape as a whole.
Further, on the basis of the above embodiment, the bracket includes at least one; and a chute which is inclined is arranged at the position corresponding to any bracket and the umbrella-shaped toothed roller 2, a fixed shaft penetrates through the chute, and one end of the fixed shaft is fixedly connected with the outer side wall of the umbrella-shaped toothed roller 2.
The present embodiment is based on the above-described embodiments, and a specific connection structure between the umbrella-shaped toothed roller 2 and the bracket is described. The connection mode of the umbrella-shaped toothed roller 2 and the bracket can be specifically as follows: at least one support is arranged around the device, and the umbrella-shaped toothed roll 2 is located at a certain height of the support. An inclined chute is arranged at the height of each bracket. The inclined chute means that the whole chute is positioned at different vertical heights and is not in a vertical state.
I.e. along the length direction of the chute, is a direction of obliquely ascending or descending. A fixed shaft passes through the chute and is in contact and cross with the chute. One end of the fixed shaft is positioned at one side of the bracket, and the other end of the fixed shaft is positioned at the other side of the bracket. One end of the fixed shaft facing the umbrella-shaped toothed roller 2 is fixedly connected with the outer side wall of the umbrella-shaped toothed roller 2.
The fixed shaft and the umbrella-shaped toothed roller 2 can be of an integrated structure, namely, the fixed shaft is a shaft-shaped protruding block extending out of the outer side wall of the umbrella-shaped toothed roller 2. The fixed shaft and the umbrella-shaped toothed roller 2 can be fixedly connected together by two parts. No relative rotation or movement can occur between the fixed shaft and the umbrella-shaped toothed roller 2.
The fixed shaft and the umbrella-shaped toothed roller 2 can be integrated in the chute and move along the direction of the chute. In an initial state, namely when the device does not start to work, the fixed shaft is positioned at the bottom end of the chute, and the chute is used for fixing the fixed shaft, so that the umbrella-shaped toothed roller 2 is fixed by the bracket. Meanwhile, the sliding groove also limits and positions the movement of the fixed shaft and the umbrella-shaped toothed roller 2, so that the fixed shaft can only drive the umbrella-shaped toothed roller 2 to move along the sliding groove.

Through setting up fixed axle and spout, fixed axle and umbrella-shaped fluted roller 2 an organic whole can be along the spout removal, can realize the rotation and the reciprocates of umbrella-shaped fluted roller 2 certain range to can carry out self-adaptation to the clearance between umbrella-shaped fluted roller 2 and the toper fluted roller 1 and adjust, improve crushing efficiency and protection device not receive the damage.
On the basis of the above embodiment, further, referring to fig. 2 and 3, the support includes an annular support 9 having a circular ring shape, the annular support 9 is sleeved on the outer side of the umbrella-shaped toothed roller 2, the outer side wall of the umbrella-shaped toothed roller 2 is connected with at least three rollers 8, the rollers 8 are disposed on the annular support 9 and are uniformly distributed in the circumferential direction of the outer side wall of the umbrella-shaped toothed roller 2, inclined slide ways 14 are disposed at the annular supports 9 corresponding to at least two rollers 8, and the inclined slide ways 14 have slopes along the circumferential direction of the annular support 9 and have the same gradient direction.
This embodiment is based on the above-described embodiment, and another specific connection structure between the umbrella-shaped toothed roller 2 and the bracket is described. The specific structure of the connection between the umbrella-shaped toothed roller 2 and the bracket can be as follows: the support is made into a ring-shaped support 9. The annular bracket 9 is arranged on the periphery of the umbrella-shaped toothed roller 2, and the annular bracket 9 is fixed.
The annular bracket 9 is sleeved on the outer side of the umbrella-shaped toothed roller 2 and is perpendicular to the axial direction of the umbrella-shaped toothed roller 2. The outer side wall of the bevel gear roller 2 can be connected with at least three rollers 8 through shafts. The roller 8 may be disposed in parallel with the axial direction of the umbrella-shaped toothed roller 2. And the roller 8 is placed on the annular support 9. The roller 8 is in contact with the annular support 9, and the annular support 9 plays a supporting role on the roller 8, so that the umbrella-shaped toothed roller 2 is supported and fixed. The roller 8 can rotate around the annular bracket 9, thereby driving the umbrella-shaped toothed roller 2 to rotate.
The annular support 9 can be contacted with the outer side wall of the umbrella-shaped toothed roller 2, so that no gap exists between the umbrella-shaped toothed roller 2 and the annular support 9, and the roller 8 can be ensured to be positioned on the annular support 9 when the umbrella-shaped toothed roller 2 rotates, thereby being beneficial to the stability of device operation.
Further, grooves matched with the rollers 8 can be formed in the annular support 9, so that the rollers 8 are placed in the grooves and rotate in the grooves.
Further, the ring support 9 may be located at the upper portion of the umbrella-shaped toothed roller 2, or may be located at the middle portion and the lower and bottom portions, which is not limited.
At least three rollers 8 are provided to facilitate stable support of the umbrella-shaped toothed roller 2.
Further, an inclined slide 14 is provided on the ring support 9 below the at least two rollers 8. The inclined slide 14 is an inclined surface or groove with a certain gradient where the annular bracket 9 contacts the roller 8.
The inclined slide way 14 has a gradient along the circumferential direction of the annular bracket 9, namely, has a gradient on the movement track of the roller 8, so that the roller 8 drives the umbrella-shaped toothed roller 2 to rotate along the inclined slide way 14 and simultaneously displace in the vertical direction, namely, move up and down.
Further, the inclined slide ways 14 are arranged below at least two rollers 8 to ensure that the umbrella-shaped toothed roller 2 moves up and down and ensure that the umbrella-shaped toothed roller 2 moves up and down uniformly. If only one inclined slideway is provided, the umbrella-shaped toothed roller 2 only moves up and down at the position, and the umbrella-shaped toothed roller 2 is inclined and moves unevenly.
Preferably, inclined ramps 14 are provided at the rollers 8 on opposite sides of the circumference of the umbrella-shaped toothed roller 2.
Further, the inclination of the inclined chute 14 and the inclination of the chute, i.e., the displacement difference in the vertical direction, may be set according to the degree of difficulty of the crushed material. When the material is harder to crush and a larger friction force is formed on the material contact surface 3, the inclination of the inclined slide way 14 and the inclination of the slide groove can be set larger, namely the gradient is steeper.
Like this, the rotation of umbrella-shaped fluted roller 2, umbrella-shaped fluted roller 2 can remove in slope slide 14 or spout and produce great vertical displacement to increase umbrella-shaped fluted roller 2 and the clearance of toper fluted roller 1 bottom fast, discharge the material smoothly, avoid the material to cause the damage to the device.
And when the material is easy to crush and the friction force formed on the material contact surface 3 is small, the inclination of the inclined slide way 14 and the inclination of the slide way can be set small, namely the gradient is relatively slow. Therefore, the friction force of the material to the bevel gear roller 2 is not large at this time, the device is not damaged, and therefore, the gap between the bevel gear roller 2 and the bottom of the conical gear roller 1 is not required to be too large.
Further, referring to fig. 3, at least one weight groove 10 is provided on the outer side wall of the umbrella-shaped toothed roller 2, and a weight 11 is placed in the weight groove 10.
In this embodiment, based on the above embodiment, the weight 11 is added to the umbrella-shaped toothed roller 2. The weight 11 is integrated with the umbrella-shaped toothed roller 2, and can increase the weight of the umbrella-shaped toothed roller 2. On the one hand, the friction force of the whole crushing device on the internal materials is set to be one degree, and on the other hand, when the umbrella-shaped tooth roller 2 moves obliquely upwards, a force for downwards recovering the original device is provided, so that the whole device can be automatically adjusted.
For the first aspect, specifically, if the weight 11 is not arranged on the umbrella-shaped toothed roller 2, the umbrella-shaped toothed roller 2 is pushed to move by the friction force of the material on the contact surface inside the crushing device because the self weight of the umbrella-shaped toothed roller 2 is limited, so that the whole crushing device cannot bear too large friction force of the material, but is unfavorable for crushing the material.
The weight 11 is arranged on the umbrella-shaped tooth roller 2, and a downward force is applied to the umbrella-shaped tooth roller 2, so that the crushing device can bear a certain material friction force. When the friction force of the material in the crushing device to the umbrella-shaped toothed roller 2 exceeds the force exerted by the weight pair, the umbrella-shaped toothed roller 2 moves.
Therefore, the crushing device can bear certain material friction force, and is favorable for obtaining a better material crushing effect.
For the second aspect, when the friction force of the material to the contact surface is greater than a certain degree, the umbrella-shaped toothed roller 2 rotates and moves, so that the material can be smoothly discharged out of the device, and the friction force of the material to the contact surface is reduced. Once the friction force is reduced, the umbrella-shaped toothed roller 2 moves obliquely downwards under the pressure of the weight 11, and the initial device is restored, so that the smooth continuous and efficient operation of the whole device is ensured.
Further, in the case that the umbrella-shaped toothed roller 2 is connected with the bracket through the fixed shaft and the sliding groove, the other end of the fixed shaft can be connected with the spring or the weight 11. The springs and weights 11 are also used to increase the degree of friction of the crushing device against the material and to provide the umbrella-shaped toothed roller 2 with a force to return to its original state.
Further, the bearing degree of the crushing device on the material resistance can be set by setting parameters of the spring, such as the force required for pulling the spring apart. The bearing degree of the crushing device on the material resistance is set by setting the weight of the weight 11.
Further, the bearing degree of the crushing device on the material resistance can be set according to different types of materials to be crushed, namely, the types of springs or the weight of the weight 11 are set.
Further, the weight groove 10 may be a groove provided on the outer sidewall of the umbrella-shaped toothed roller 2, and the weight 11 is placed in the groove. The weight groove 10 may be a protrusion provided on the outer sidewall of the umbrella-shaped toothed roller 2, the protrusion may be inserted into the middle of the weight 11, and a stopper may be provided at the bottom of the protrusion to fix the weight. This is not limited thereto.
On the basis of the embodiment, further, the outer surface of the conical tooth roller 1 and the inner surface of the umbrella-shaped tooth roller 2 are provided with teeth, and the teeth on the outer surface of the conical tooth roller 1 are radial in the axial direction; the teeth on the inner surface of the bevel gear roller 2 are radial in the axial direction, and gaps exist between the teeth on the outer surface of the conical gear roller 1 and the teeth on the inner surface of the bevel gear roller 2.
In this embodiment, based on the above embodiment, teeth are added on the outer surface of the conical toothed roller 1 and the inner surface of the umbrella-shaped toothed roller 2, so that the friction force of the contact surface against the material can be improved, and the crushing efficiency can be improved.
A plurality of teeth may be uniformly provided on the outer surface of the conical toothed roller 1 and the inner surface of the umbrella-shaped toothed roller 2. Specifically, the teeth may be conical, knife-edge, or any regular or irregular shaped projections, which is not limited to this, in order to increase the friction force of the contact surface against the material.
The teeth on the outer surface of the tapered toothed roller 1 may be radially axially directed on the surface along the central axis of the tapered toothed roller 1. Specifically, the teeth are a plurality of convex blocks uniformly distributed on the outer surface of the conical tooth roller 1.
One end of each lug starts from the central axis of the conical tooth roller 1, namely from the tip of the conical tooth roller 1. The other end of the projection faces the opposite end of the tip of the tapered roller 1. Overall, the projections appear radial from a center to a circle around. And each projection extends from one end of the outer surface of the tapered roller 1 to the other end.
I.e. the length of each bump is the same as the length of the outer surface of the conical toothed roller 1. Further, one end of each of the projections which is not in contact with the outer surface of the tapered roller 1 may be provided as a pointed shape, which is advantageous in improving the crushing efficiency.
The arrangement of the teeth on the inner surface of the umbrella-shaped toothed roller 2 can be the same as the arrangement structure of the teeth on the outer surface of the conical toothed roller 1, and the description is omitted.
Further, the specific arrangement structure of the teeth on the bevel gear roller 2 and the bevel gear roller 1 may be the same or different, and is not limited thereto.
Further, the teeth on the inner surface of the bevel gear roller 2 and the teeth on the outer surface of the conical gear roller 1 do not intersect and do not contact, that is, a gap exists between the teeth. The teeth on the two contact surfaces are set to have gaps and are not crossed, so that the crushing device is prevented from being blocked due to the crossing of the teeth, and the crushing device can be protected and the crushing efficiency is improved.
On the basis of the above embodiment, further, the top end of the bevel gear roller 2 is provided with an opening, the cross-sectional diameters of the conical gear roller 1 and the bevel gear roller 2 are sequentially increased from top to bottom, and the gap between the conical gear roller 1 and the bevel gear roller 2 is sequentially decreased from top to bottom.
The present embodiment is based on the above-described embodiments, and further description is given of the bevel gear roller 2 and the tapered gear roller 1. The umbrella-shaped toothed roller 2 is integrally in a frustum shape. And the material is added from the top of the device, and the top of the umbrella-shaped toothed roller 2 is provided with an opening which is a feed inlet 5, so that the material can be conveniently added.
The conical tooth roller 1 and the umbrella tooth roller 2 are specifically arranged, wherein one end with smaller section diameter is located above, and one end with larger section diameter is located below. And the gap between the conical tooth roller 1 and the umbrella tooth roller 2 is sequentially reduced from top to bottom.
The gaps between the material contact surfaces 3 are set to be sequentially reduced from top to bottom, so that the linear speed of the opposite movement of the material contact surfaces 3 can be gradually increased from top to bottom. Therefore, the linear speed of the upper-end large-grain-size material is smaller, and the encountered resistance is smaller than that of the lower-end small-grain-size material, so that the purposes of preventing the material from being blocked and blocked are achieved.
In addition, the upper gap is larger, and the material can be conveniently added. The gap between the conical tooth roller 1 and the bottom of the umbrella-shaped tooth roller 2 is smaller, and the conical tooth roller and the umbrella-shaped tooth roller are the discharge slits 6. The bottom clearance is set as a discharge slit 6, so that the crushing effect can be ensured. Since the material is crushed and leaks from the bottom gap, the material must be crushed to a certain extent, i.e. to a certain extent particles are small in order to leak from the discharge slit 6.
Further, in the above embodiment, the cone-umbrella coupled pulverizing device further includes: a vibrating screen 12 and a screen residue collection box 13; the vibrating screen 12 is of an inverted umbrella-shaped hollow shell structure, the diameter of the cross section of the vibrating screen 12 is sequentially reduced from top to bottom, openings are formed in the top and the bottom of the vibrating screen, the top of the vibrating screen 12 is inserted from the bottom of the umbrella-shaped toothed roller 2, the top of the vibrating screen 12 is in contact connection with the inner side wall of the umbrella-shaped toothed roller 2, and a screen residue collecting box 13 is arranged below the opening of the bottom of the vibrating screen 12.

The material in the gap between the conical toothed roller 1 and the umbrella-shaped toothed roller 2 falls into the vibrating screen 12 during the falling process. The side wall of the vibrating screen 12 is in a mesh structure for screening crushed materials.
The size of the material particles falling into the vibrating screen 12, if smaller than the mesh size of the vibrating screen 12, can pass through the vibrating screen 12 and finally fall out from the gap between the conical toothed roller 1 and the bottom of the umbrella-shaped toothed roller 2. If the size of the material particles falling into the vibrating screen 12 is larger than the mesh size of the vibrating screen 12, the material cannot pass through the vibrating screen 12, can only fall out from the bottom opening of the vibrating screen 12 and finally fall into the screen residue collecting box 13 along the inner side wall of the vibrating screen 12.
The vibrating screen 12 can be used for screening crushed materials, and qualified materials fall out from gaps between the bottoms of the conical toothed roller 1 and the umbrella-shaped toothed roller 2, wherein the gaps are annular and are positioned at the periphery.
