[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0024] Please refer to the attached Figure 1-Figure 5As shown, the utility model provides a technical solution: a pipe valve that is easy to disassemble and assemble, including a valve body 10, the upper and lower ends of the valve body 10 are fixedly connected to a mounting plate 101, and the two mounting plates 101 are respectively provided with a crushing bin connector 11 and a discharge pipe connector 12 on the side away from each other, and nuts 20 are threadedly installed at the four corners between the valve body 10 and the crushing bin connector 11 and the discharge pipe connector 12, and a circular cavity 201 is opened in the nut 20, and a fixing mechanism is provided in the circular cavity 201, and the fixing mechanism includes a rotating shaft 21 rotatably installed in the circular cavity 201, and four trapezoidal blocks 23 are equidistantly provided on the outer surface of the rotating shaft 21, and the four trapezoidal blocks 23 are connected to the rotating shaft 21. A first spring 24 is fixedly installed between them. Through the four first springs 24, when the rotating shaft 21 is rotated to make the four trapezoidal blocks 23 coincide with the four sliding holes 202, the four first springs 24 can push the four trapezoidal blocks 23 to slide out of the four sliding holes 202 respectively under the elastic force of the four first springs 24. Sliding holes 202 are opened at the inner wall of the circular cavity 201 corresponding to the four trapezoidal blocks 23. The four trapezoidal blocks 23 are slidably installed in the four sliding holes 202 respectively and are slidably connected to the crushing bin connector 11 and the discharge pipe connector 12 respectively. Through the fixing mechanism, it can be prevented that the nut 20 is loosened due to shaking during the operation of the crusher, thereby making the pipe valve connection unstable.

[0025] In one embodiment of the present invention, Figure 5 As shown, four transmission shafts 22 are fixedly installed at equal intervals on the outer surface of the rotating shaft 21. The four transmission shafts 22, and the ends of the four transmission shafts 22 away from the rotating shaft 21 respectively pass through four trapezoidal blocks 23 and are slidably connected with the four trapezoidal blocks 23. The four first springs 24 are respectively slidably sleeved on the outer surfaces of the four transmission shafts 22. When the four trapezoidal blocks 23 rotate, under the restriction of the four transmission shafts 22, the four first springs 24 are prevented from bending, resulting in the four trapezoidal blocks 23 being unable to shrink in the circular cavity 201.

[0026] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the upper end of the rotating shaft 21 is fixedly connected to a round block 25, the end of the round block 25 away from the rotating shaft 21 passes through the nut 20 and is rotatably connected to the nut 20, the end of the round block 25 away from the rotating shaft 21 is fixedly connected to the knob 26, and a baffle 211 is fixedly installed at the connection between the round block 25 and the rotating shaft 21, and the baffle 211 is rotatably installed in the circular cavity 201. By setting the baffle 211, the rotating shaft 21 is prevented from escaping from the circular cavity 201.

[0027] Specifically, when removing the pipe valve, the knob 26 is manually turned first to further rotate the round block 25 to drive the rotating shaft 21 to rotate, and then the inclined surfaces of the four trapezoidal blocks 23 are respectively slid on one side of the four sliding holes 202 in the clockwise direction, so that the trapezoidal blocks 23 can squeeze the first spring 24 to slide on the transmission shaft 22, thereby disengaging from the sliding hole 202, further releasing the lock between the pipe valve and the crushing bin connector 11 or the discharge pipe connector 12, and then the nut 20 is rotated by a tool to remove the pipe valve. The disassembly and assembly process is relatively simple.

[0028] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a runner 13 is rotatably installed between the inner wall of one end of the valve body 10 close to the crushing bin connector 11, and a number of push plates 131 are fixedly installed on the outer surface of the runner 13 at equal intervals. A micro motor 14 is fixedly installed on the outside of the valve body 10, and the output end of the micro motor 14 passes through the valve body 10 and is fixedly connected to the runner 13. By starting the micro motor 14, the runner 13 can be driven to rotate, thereby driving the several push plates 131 on the runner 13 to rotate, further pushing the material in the crushing bin of the crusher into the valve body 10, while avoiding blockage at the connection between the valve body 10 and the crushing bin connector 11.

[0029] In one embodiment of the present invention, Figure 2 As shown, the valve body 10 is provided with an opening and closing plate 30 below the plurality of push plates 131 , and one end of the opening and closing plate 30 is rotatably mounted on the right side of the inner wall of the valve body 10 . By controlling the opening and closing angle of the opening and closing plate 30 , the outflow speed of the material in the valve body 10 is controlled.

[0030] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the opening and closing plate 30 is fixedly connected to two first fixed blocks 301 and two supporting blocks 102 on both sides of the lower end away from the rotation axis of the opening and closing plate 30 and the inner wall of the valve body 10 respectively. The two first fixed blocks 301 and the two supporting blocks 102 are rotatably installed with rotating blocks 31. Two second springs 34 are fixedly installed between the four rotating blocks 31. The four rotating blocks 31 are fixedly connected to a round rod 311. The two second springs 34 are slidably sleeved on the four round rods 311 respectively. The material in the valve body 10 falls onto the opening and closing plate 30. Under the action of gravity, the two second springs 34 between the two first fixed blocks 301 and the two supporting blocks 102 are squeezed, and a gap is generated between one end of the opening and closing plate 30 and the valve body 10, and then the material flows into the discharge pipe from the gap.

[0031] In one embodiment of the present invention, Figure 3 and Figure 4As shown, the valve body 10 is provided with a sleeve rod 32 inserted at the lower end of the opening and closing plate 30, one end of the sleeve rod 32 passes through the valve body 10 and is slidably connected to the valve body 10, one end of the sleeve rod 32 passing through the valve body 10 is fixedly connected to the rocking wheel 33, and the end of the sleeve rod 32 away from the rocking wheel 33 is fixedly connected to the stopper 321, the sleeve rod 32 is provided with a threaded rod 37, the threaded rod 37 passes through the stopper 321 and is threadedly connected to the stopper 321, and one end of the threaded rod 37 passing through the stopper 321 is fixedly connected to the connecting block 36, and the second fixed block 302 is fixedly installed between the two first fixed blocks 301 at the lower end of the opening and closing plate 30, and a transmission rod 35 is provided between the second fixed block 302 and the connecting block 36, and the two ends of the transmission rod 35 are rotatably connected to the second fixed block 302 and the connecting block 36 respectively.

[0032] Specifically, when the maximum opening and closing angle of the opening and closing plate 30 needs to be adjusted, the rocker 33 is rotated to drive the stopper 321 on the sleeve rod 32 to move on the threaded rod 37. When the opening and closing plate 30 is deflected by the gravity of the material, the transmission rod 35 pushes the threaded rod 37, and the threaded rod 37 pushes the sleeve rod 32 to slide in the valve body 10. By adjusting the position of the stopper 321 on the threaded rod 37, the distance between the stopper 321 and the inner wall of the valve body 10 is changed. Under the obstruction of the stopper 321, the maximum opening and closing angle of the opening and closing plate 30 can be adjusted.

[0033] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
