Detailed Description
The utility model will be further described with reference to the drawings and examples.
As shown in fig. 1, the rod-shaped material crushing device comprises a rod-shaped material primary crushing mechanism 1 and a secondary crushing mechanism 2, wherein a feed inlet of the secondary crushing mechanism 2 is connected with a crushing chamber discharge outlet of the rod-shaped material primary crushing mechanism 1. The secondary pulverizing mechanism 2 may employ various conventional pulverizing structures such as: a hammer type structure or a tooth type structure. In order to meet the preliminary pulverizing requirements of a rod-shaped material having a large diameter and a certain length such as corncob or corn cob, the rod-shaped material primary pulverizing mechanism 1 of the present utility model includes a housing 11, and a first pulverizing roller 12 and a second pulverizing roller 13 rotatably connected to the housing 11, respectively, for pulverizing the rod-shaped material, as shown in fig. 2 and 3. The shell 11 is provided with a crushing chamber 111 for crushing rod-shaped materials, the first crushing roller 12 and the second crushing roller 13 are arranged in the crushing chamber 111 side by side, and a space is arranged between the first crushing roller 12 and the second crushing roller 13 to form a crushing channel 5. One end of the second crushing roller 13 is in transmission connection with the first crushing roller 12 through the opposite synchronous transmission mechanism 3. The first crushing roller 12 is provided with a first disc-shaped cutter 14, the second crushing roller 13 is provided with a second disc-shaped cutter 15 matched with the first disc-shaped cutter 14, the first disc-shaped cutter 14 and the second disc-shaped cutter 15 are sequentially staggered along the axis direction of the first crushing roller 12, and the edge of the first disc-shaped cutter 14 or/and the edge of the second disc-shaped cutter 15 is/are provided with a clamping groove 141 for clamping the rod-shaped material so as to feed the rod-shaped material into the crushing channel 5. The clamping groove 141 is specifically configured according to the outer diameter of the rod-shaped material, the width is generally larger than the outer diameter of the rod-shaped material, and the depth is generally larger than the radius of the rod-shaped material.
In order to prevent the rod-shaped material from passing between the adjacent two disc-shaped cutters and not to the purpose of crushing the material, it is understood that in the present utility model, the distance between the adjacent first disc-shaped cutters 14 and the second disc-shaped cutters 15 should be set correspondingly in the radial direction according to the diameter of the rod-shaped material to be processed, and should be generally smaller than the diameter of the rod-shaped material to be processed.
In the present utility model, the first disk-shaped cutter 14 and the second disk-shaped cutter 15 may each be one or more, and typically, a plurality of cutters.
As shown in fig. 3, the rod-shaped material pulverizing apparatus of the present utility model is used by driving the second pulverizing roller 13 to rotate counterclockwise by a motor. Since one end of the second crushing roller 13 is in transmission connection with the first crushing roller 12 through the opposite synchronous transmission mechanism 3, the second crushing roller 13 can drive the first crushing roller 12 to synchronously rotate clockwise through the opposite synchronous transmission mechanism 3 when rotating anticlockwise. When the rod-shaped material crushing device crushes the rod-shaped material, the rod-shaped material 4 is fed into the crushing chamber 111 from the feed inlet 112 above the crushing channel 5, the rod-shaped material 4 cannot pass through the space between the first crushing roller 12 and the second crushing roller 13 wholly under the action of the first disc-shaped cutter 14 and the second disc-shaped cutter 15, and generally lies on the first disc-shaped cutter 14 and the second disc-shaped cutter 15 under the action of gravity. Because the edge of the first disc-shaped cutter 14 or/(and) the edge of the second disc-shaped cutter 15 is provided with the clamping groove 141, in the rotating process of the first disc-shaped cutter 14 and the second disc-shaped cutter 15, rod-shaped materials can be clamped into the clamping groove 141 under the action of gravity, and the rod-shaped materials 4 rotate along with the first disc-shaped cutter 14 or the second disc-shaped cutter 15 through the limiting function of the clamping groove 141, so that the rod-shaped materials smoothly pass through the crushing channel 5, and are extruded and crushed through the cooperation of the first disc-shaped cutter 14 and the second disc-shaped cutter 15 when passing through, so that the purpose of forming relatively uniform preliminary crushed pieces is achieved. The primarily crushed material flows into the secondary crushing mechanism 2 from a discharge hole below the crushing chamber, and is further crushed by the secondary crushing mechanism 2. Because the crushed material of the secondary crushing mechanism 2 is primarily crushed by the rod-shaped material primary crushing mechanism to be smaller, the crushed material of the secondary crushing mechanism 2 is smaller, and the processing efficiency of the rod-shaped material is also ensured.
The first-stage crushing mechanism for the rod-shaped materials meets the preliminary crushing processing requirements of the rod-shaped materials with larger diameter and certain length, such as corncobs or corn cobs, and the particles after the preliminary crushing processing are uniform, so that the crushing efficiency of the rod-shaped materials can be improved.
In order to improve the preliminary crushing efficiency, it is preferable that the edges of the first disk-shaped cutter 14 and the edges of the second disk-shaped cutter 15 are both provided with the clamping groove 141, and the clamping groove 141 on the first disk-shaped cutter 14 and the clamping groove 141 of the second disk-shaped cutter 15 are arranged in a staggered manner. The clamping groove 141 on the first disc-shaped cutter 14 and the clamping groove 141 of the second disc-shaped cutter 15 are arranged in a staggered manner, namely: when the two are rotated in opposite directions, the situation that the clamping groove 141 on the first disc-shaped cutter 14 is opposite to the opening of the clamping groove 141 of the second disc-shaped cutter 15 does not exist, so that the rod-shaped materials are crushed. When the clamping grooves 141 are formed in the edges of the first disc-shaped cutter 14 and the edges of the second disc-shaped cutter 15, the materials can be brought into the crushing channel 5 through the first disc-shaped cutter 14 and the second disc-shaped cutter 15, so that the crushing efficiency is higher.
In order to ensure that the crushing efficiency is generally multiple, in the embodiment of the present utility model, the edge of the first disc-shaped cutter 14 is uniformly provided with 4 clamping grooves 141, and the edge of the second disc-shaped cutter 15 is also uniformly provided with 4 clamping grooves 141.
In the embodiment of the utility model, the opposite synchronous transmission mechanism 3 comprises a first gear 31 and a second gear 32 meshed with the first gear 31, wherein the first gear 31 is arranged on the first crushing roller 12, and the second gear 32 is arranged on the second crushing roller 13.
