By using the structural characteristics of the transmission shaft rod 4, the linkage shaft rod 5 can be retracted into the transmission shaft rod 4 during the sliding process of the linkage shaft rod 5 to the transmission shaft rod 4, and the linkage shaft rod 5 can slide on the transmission shaft rod 4 while the transmission shaft rod 4 rotates, so that the linkage shaft rod 5 can rotate with the transmission shaft rod 4.

[0026] The transmission assembly 8 comprises a transmission screw 10, a transmission motor 11, a displacement seat 12, a displacement frame 13, and a hydraulic rod 14.

[0028] Embodiment two

[0029] Please refer to Figures 1-4 The embodiment provides a technical scheme based on the embodiment one: the support assembly 9 comprises an extension seat 18, a guide slide rod 19, a guide plate 20, a positioning arc plate 21, and a spiral spring 22. One side of the transmission seat 3 is fixedly connected with the extension seat 18. The middle part of the extension seat 18 is vertically slidingly connected with the guide slide rod 19. The bottom end of the guide slide rod 19 is fixedly connected with the guide plate 20. The top end of the guide slide rod 19 is fixedly connected with the positioning arc plate 21. The bottom end of the positioning arc plate 21 and the extension seat 18 are fixedly connected with the spiral spring 22. One side of the transmission seat 3 is fixedly connected with an electric push rod 23. The output end of the electric push rod 23 is fixedly connected with a guide seat 24. The linkage shaft rod 5 is also rotatably connected to the top end of the guide seat 24.

[0030] Specifically, the guide plate 20 is inclined, and the bottom of the guide seat 24 is provided with a slope corresponding to the slope of the guide plate 20, and the slope is in close contact with the slope of the guide plate 20. When the guide seat 24 moves towards the guide plate 20, the slope on the guide seat 24 can be in close contact with the slope of the guide plate 20. Since the guide seat 24 is linearly displaced, the guide slide rod 19 can be driven to move upwards under the cooperation of the slope and the slope, so that the positioning arc plate 21 contacts the linkage shaft 5.

[0031] Meanwhile, the contents not described in detail in the specification are all prior art known to those skilled in the art.

[0032] The working principle is as follows: first, the driving motor 15 is started to drive the driving spur gear 16 to rotate the corresponding gear disc 17, thereby driving the transmission shaft 4 to rotate. The transmission shaft 4 is connected with the linkage shaft 5, so that the linkage shaft 5 can drive the output shaft 6 to rotate, thereby providing power for the slurry pump body 2. When the transmission speed of the slurry pump body 2 needs to be adjusted, the electric push rod 23 is first started to pull the guide seat 24 to linearly displace. The guide seat 24 is connected with the linkage shaft 5, so that the linkage shaft 5 can move away from the output shaft 6, thereby separating the two gear discs 7, and interrupting the power of the output shaft 6. At the same time, when the guide seat 24 is displaced, the guide plate 20 can be pressed to drive the positioning arc plate 21 to contact the linkage shaft 5 through the guide slide rod 19, so that the linkage shaft 5 stops rotating;

[0033] Then, the hydraulic rod 14 is started to push the displacement frame 13 to slide, thereby driving the driving spur gear 16 to move away from the gear disc 17. Subsequently, the transmission motor 11 is started to drive the transmission screw 10 to rotate. The transmission screw 10 is connected with the displacement seat 12, so that the displacement seat 12 can displace along the transmission screw 10 until the driving spur gear 16 reaches the designated gear disc 17. Then, the hydraulic rod 14 is started to pull the driving spur gear 16 to engage with the corresponding gear disc 17. When the driving spur gear 16 engages with the gear disc 17 which is larger than the diameter of the driving spur gear 16, the transmission shaft 4 will rotate slowly. When the driving spur gear 16 engages with the gear disc 17 which is smaller than the diameter of the driving spur gear 16, the transmission shaft 4 will rotate faster.

[0034] Finally, the electric push rod 23 is started to push the guide seat 24 to displace until the two gear discs 7 are engaged with each other. After the guide seat 24 gradually moves away from the guide plate 20, the positioning arc plate 21 can be pulled away from the linkage shaft 5 by the helical spring 22, so that the linkage shaft 5 can drive the output shaft 6 to rotate.
