[0028] By setting up a pitch-changing mechanism and starting the hydraulic cylinder 9, the hydraulic cylinder 9 drives the pitch-changing block 4 fixed at the output end to move. Several pitch-changing blocks 4 are sleeved on the connecting rod 3, and a connecting rod 5 is rotatably installed between two adjacent pitch-changing blocks 4. When the hydraulic cylinder 9 is started, the hydraulic cylinder 9 pushes the first pitch-changing block 4 to move, and the first pitch-changing block 4 drives the remaining pitch-changing blocks 4 to move through the connecting rod 5, so that the transmission ratio can be flexibly adjusted according to actual needs, thereby improving the efficiency and energy utilization of the transmission system. It has strong adaptability and is suitable for various engineering and mechanical application scenarios.

[0029] Among them Figure 1 and Figure 2 As shown, two rotating shafts 11 are rotatably mounted on the support frame 10, a supporting plate 11 is fixedly mounted on the back of the support frame 10, a motor 12 is fixedly mounted on the top of the supporting plate 11, a corresponding rotating shaft 13 is fixedly mounted on the output end of the motor 12, and pulleys 14 are respectively fixedly mounted on the two rotating shafts 13, and a belt 15 is sleeved between the two pulleys 14.

When there is a material 20 stopping, the second hydraulic cylinder 31 starts and drives the push plate 32 to push the material 20, so that the material 20 continues to be transported, avoiding the accumulation of too much material 20 and affecting the work efficiency or causing certain harm to the equipment.

[0039] A specific application of this embodiment is as follows: The material 20 is transported from the belt 15 to the receiving plate 29, and the sensor 30 detects the receiving plate 29.

The top of the connecting plate 21 is fixedly connected to the U-shaped plate 2. A connecting rod 3 is fixedly installed at the bottom of the U-shaped plate 2. A plurality of variable pitch blocks 4 are sleeved on the connecting rod 3. A pushing plate is fixedly installed at the top of the plurality of variable pitch blocks 4. The bottoms of two adjacent variable pitch blocks 4 among the plurality of variable pitch blocks 4 are connected by a connecting rod 5. A hydraulic cylinder 9 is fixedly installed on the right side of the U-shaped plate 2. The output end of the hydraulic cylinder 9 is fixedly connected to the nearest variable pitch block 4. The hydraulic cylinder 9 pushes the variable pitch block 4 and then drives the remaining variable pitch blocks 4 to adjust the pitch through the connecting rod. The pushing plate on the variable pitch block 4 is slidably connected to the limiting groove 6 on the U-shaped plate 2, thereby pushing the material 20 on the cross plate 16.
