Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings.

Referring to fig. 1-2-3, a single-shaft shredder for shredding pipes comprises a frame 1, a shredding chamber 2 arranged on the frame 1, a knife roll 3 arranged in the shredding chamber 2 and rotating around the axial lead direction, a fixed knife (not shown in the figure) arranged on the inner wall of the shredding chamber 2 and used for shredding materials in cooperation with the knife roll 3, a first driving mechanism 4 used for driving the knife roll 3 to rotate, a bin 5 which is arranged on the frame 1 in a sliding manner and can pass through the upper part of the knife roll 3, and a second driving mechanism (not shown in the figure) used for driving the bin 5 to move, this unipolar shredder is still including locating 5 locating parts 6 of the perpendicular rotor 3 axis direction one side inner wall of feed bin, and locating part 6 includes spacing body 61, locates on the spacing body 61 and along the spacing tooth 62 that the horizontal direction extends, has spacing face 621 on the spacing tooth 62, and the one end that rotor 3 was kept away from to tubular product is contradicted on spacing face 621. The limiting part 6 is welded on the inner wall of the bin 5, and the limiting body 61 extends downwards along the length direction of the vertical knife roll 3. The limiting parts 6 are multiple, and the limiting parts 6 are arranged on the inner wall of the storage bin 5 at intervals along the length direction parallel to the knife roller 3. The limiting teeth 62 are multiple, and the limiting teeth 62 are arranged at intervals along the extending direction of the limiting body 61.

Here, the rotation direction of the knife roll 3 is opposite to the feeding direction, and it should be noted that the front and the back are both front and back based on the feeding direction. Locating part 6 sets up in 5 back walls of feed bin, when tubular product leads to the unstability to incline forward because of the part is torn up, a stroke of feed bin 5 is ended, and 5 backward movements of feed bin push tubular product to 5 back walls of feed bin to contradict on locating part 6, spacing tooth 62 can effectually support tubular product with the cooperation of rotor 3, make tubular product can't continue the slope, make more effectual tearing up of tubular product in feed bin 5, work efficiency is high and output is high. The spacing arrangement of the plurality of limiting teeth 62 enables the limiting member 6 to adapt to pipes with different lengths.

In another arrangement of the limiting members 6 of the present embodiment, there is a plurality of limiting members 6, and the limiting members 6 are arranged in a staggered manner in pairs, wherein, in every two adjacent limiting members 6, an end of one of the limiting members 6 and a center of the other one of the limiting members are located on the same horizontal plane.

The first driving mechanism 4 comprises a motor 41 and a speed reducer 42, the motor 41 is connected with the speed reducer 42 through a belt 43, the motor 41 is installed at the bottom of the frame 1, the speed reducer 42 is installed at one side end of the knife roll 3, and the output end of the speed reducer 42 is connected with the end of the knife roll 3 through a coupler 7. Through the setting of shaft coupling 7, the spindle nose of protection rotor 3 that can be better and speed reducer 42 are not fragile, the change of speed reducer 42 of being convenient for simultaneously.

This unipolar shredder still includes along perpendicular rotor 3 the extending direction locate frame 1 on slide bar 8, set up the slide opening 9 of tip under 5 both sides of feed bin, slide bar 8 has two and is located the both sides of feed bin 5, and feed bin 5 is located on slide bar 8 through the gliding cover of slide opening 9. Through the arrangement of the sliding rod 8 and the sliding hole 9, the storage bin 5 can stably feed materials and is not easy to shake, and the noise is low. Here, the bin 5 is driven to slide by a second driving mechanism 6, which is a driving cylinder.
