Detailed Description
To facilitate an understanding of the utility model, the utility model is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, in the present embodiment, a pulverizing hopper comprises a hopper body 1, a plurality of feed rollers 2 and a crushing roller 3, wherein the hopper body 1 is funnel-shaped, has an inclined bottom surface 11 and is provided with a discharge opening 12 at the bottom of the bottom surface 11.
In this embodiment, the plurality of feed rollers 2 are disposed in the inner cavity of the hopper body 1, the plurality of feed rollers 2 are arranged above the bottom surface 11 along the inclined direction of the bottom surface 11, both ends of the plurality of feed rollers 2 at this time are rotatably fixed on both side walls of the hopper body 1, and one end of each feed roller 2 is synchronously driven and connected by a synchronous belt and driven by an external driving motor to make each feed roller 2 synchronously rotate at a high speed. The feed rolls 2 are all rotated in the same direction, wherein the feed rolls 2 are all rotated clockwise with reference to fig. 1.
Further, the roll surface of each feed roll 2 is formed with a screw guide strip 21, wherein the screw guide strip 21 of the present embodiment is arranged on the roll surface of the feed roll 2 in a manner of extending towards the symmetrical screw threads on both sides of the feed roll 2 by taking the middle of the feed roll 2 as a boundary. The threaded guide strip 21 may be formed on the roll surface of the feed roll 2 by welding, screwing, or the like. The spiral characteristic of the thread guide belt 21 is utilized to enable the materials to be gradually accumulated towards the middle of the feed roller 2 during the downward conveying of the materials along with the feed roller 2, so that the conveying and the subsequent crushing work are more convenient.
Therefore, materials are poured into the hopper body 1 and move towards the discharge port 12 under the rotating traction of each feeding roller 2, so that the risk of accumulation and blockage of the materials is avoided; secondly, due to the fast rotation speed of each feed roll 2, the material flow between two adjacent feed rolls 2 follows the rotation direction of the feed rolls 2, so that hard objects such as stones cannot bite into the gap between the two feed rolls 2.
In the present embodiment, the crushing roller 3 is disposed in the inner cavity of the hopper body 1, specifically, the crushing roller 3 is located above the discharge opening 12 and adjacent to the feeding roller 2 at the lowest position, and both ends of the crushing roller 3 are rotatably fixed on both side walls of the hopper body 1 and driven to rotate by an external driving motor. Next, the crushing roller 3 rotates in a direction opposite to the rotation direction of the feed roller 2, and the crushing roller 3 rotates counterclockwise as shown in fig. 1, so that the crushing roller 3 rotates in a direction opposite to the feed roller 2 at the lowest position.
Through the rotation speed that makes crushing roller 3 be greater than the rotation speed of feed roller 2, can make crushing roller 3 produce bigger broken shearing force, utilize the dead weight of material and the direction effort of feed roller 2 simultaneously, make the material can't break away from crushing roller 3, ensure that crushing roller 3 can carry out the breakage to the material.
Further, a plurality of crushing blocks 31 are formed on the roller surface of the crushing roller 3, and the crushing blocks 31 are used for crushing materials, wherein the plurality of crushing blocks 31 are divided into a plurality of rows and annularly arranged on the roller surface of the crushing roller 3, and the crushing blocks 31 in each row are axially and equidistantly arranged. The broken block 31 is of a blocky and conical structure, the sharp ridge line of the broken block at the moment is sharp, the material is easy to break, and the processing is more convenient.
The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents to the embodiments of the utility model without departing from the scope of the utility model as set forth in the claims below. Therefore, equivalent changes made according to the spirit of the present invention should be covered within the protection scope of the present invention without departing from the contents of the technical scheme of the present invention.
