When the paddle 5 is out of contact with the contact of the position sensor 4, the delay relay 7 controls the operation of the belt conveyor. After the paddle 5 is out of contact with the contact of the position sensor 4, the delay relay 7 stops the belt conveyor after a preset delay time, and the material 14 enters the belt funnel 12 from the head wheel through the belt transport. When the material 14 in the belt funnel 12 is blocked and spreads upward, the material 14 will squeeze the receiving plate 1, and the receiving plate 1 will be displaced backward. The spring 8 resets the part and drives the rotating shaft 2 to rotate the paddle 5 to disengage the contact of the position sensor 4. The position sensor 4 transmits the signal to the delay relay 7 through the transmission line 15. After the delay relay 7 reaches the preset time, it transmits the signal to the control box 6, and the control box 6 controls the belt transmission mechanism to stop. When individual materials 14 hit the receiving plate 1, due to the effect of the delay relay 7, such signals will not be transmitted.

[0039] Embodiment 2

[0040] The present invention provides a method for using the belt hopper material blocking parking device 100 as in the first embodiment.

[0041] 1. Installation and debugging stage

[0042] The receiving plate 1 is installed in the belt funnel 12 and is located in front of the belt head wheel 13 to ensure that it is accurately positioned so as to receive the extrusion of the material 14 when the material 14 in the belt funnel 12 is blocked and spreads upward;

[0043] The rotating shaft 2 is rotatably connected to the outside of the belt funnel 12, and attention is paid to the stability of the installation and the flexibility of rotation.

[0044] One end of the connecting rod 3 is fixedly connected to the receiving plate 1, and the other end extends out of the belt funnel 12 and the middle part is fixedly connected to the rotating shaft 2 to ensure a firm connection;

[0045] One end of the reset member (spring 8) is fixedly connected to the outside of the belt funnel 12, and the other end is fixedly connected to the end of the connecting rod 3 away from the receiving plate 1, and the spring 8 base is installed. The two ends of the spring 8 are respectively sleeved on the spring 8 base and the outside of the bent rod to ensure that the spring 8 is installed stably;

[0046] The position sensor 4 is fixed to the outside of the belt funnel 12, and its position is ensured to be accurate and firm by a second support rod;

[0047] The paddle 5 is fixedly connected to the rotating shaft 2 to ensure that the paddle 5 can move accurately as the rotating shaft 2 rotates.

[0048] A time delay relay 7 is installed in the control box 6 and is electrically connected to the position sensor 4 .

[0049] 2. Normal operation stage

[0050] When the belt conveyor operates normally, the material 14 is transported on the belt and enters the belt hopper 12 .

[0051] If no material blockage occurs, the material 14 passes through the belt funnel 12 smoothly, the receiving plate 1 is not excessively squeezed by the material 14 , and the paddle 5 maintains contact with the contact of the position sensor 4 .

[0052] The time delay relay 7 is in the monitoring state and does not trigger the stop operation of the belt conveyor, so the belt conveyor continues to run.

[0053] 3. Blockage Detection Stage

[0054] When material blockage occurs in the belt hopper 12 , the material 14 accumulates in the belt hopper 12 , squeezing the receiving plate 1 .

[0055] The receiving plate 1 moves under the pressure of the material 14, driving the connecting rod 3 to move. Since the middle part of the connecting rod 3 is fixedly connected to the rotating shaft 2, the movement of the receiving plate 1 drives the rotating shaft 2 to rotate.

[0056] The rotation of the rotating shaft 2 drives the paddle 5 to separate from the contact of the position sensor 4 .

[0057] 4. Equipment Stopping Stage

[0058] When the paddle 5 is out of contact with the contact of the position sensor 4, the position sensor 4 transmits a signal to the delay relay 7;

[0059] After receiving the signal, the time delay relay 7 starts timing, and the belt conveyor continues to operate so as to convey the remaining material 14 on the belt for a certain distance;

[0060] After a preset time of 2-3 seconds, the delay relay 7 is triggered to stop the belt conveyor to prevent equipment damage and production interruption due to material blockage.

[0061] V. Resumption of Operation

[0062] When the blocking problem is solved, the material 14 is separated from the receiving plate 1;

[0063] The reset member (spring 8) pushes the connecting rod 3 to rotate, so that the receiving plate 1 is reset, and at the same time drives the rotating shaft 2 to rotate, so that the paddle 5 is rotated to contact with the contact of the position sensor 4;

[0064] The position sensor 4 detects the contact signal of the paddle 5 and transmits the signal to the delay relay 7, and the delay relay 7 is in a ready state;

[0065] At this time, the belt conveyor equipment can be restarted to resume normal production.

[0066] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
