At this time, the telescopic rod 1 22 and the telescopic rod 23 can be used to further drive the support rod 51 and the bracket 61 to deflect, thereby changing the position of the injection rod 52, so that the injection end of the injection rod 52 is located in the ditch to prevent manure from leaking out, and when the bracket 61 deflects, the soil covering plate 63 can be deflected synchronously, so that the soil covering plate 63 can always remain in the horizontal direction and fit on the top of the ditch, ensuring that the soil covering plate 63 can refill the soil into the ditch; S2, the moving component drives the device to move as a whole, and at the same time drives the driving shaft 41 to rotate so that the canal opening mechanism 3 canalize, and transports the soil blocks in the canal opening process to both sides of the canal, and at the same time uses the injection component 5 to inject liquid manure into the canal, and uses the soil covering component 6 to refill the soil blocks on both sides of the canal into the canal after fertilization; In particular, when digging a ditch, the rotating seat 31 rotates clockwise and drives the soil delivery plate 32 and the soil breaking block 33 to rotate synchronously to dig the ditch.

When the two deflection seats 2 are connected, the bolts on the deflection seat 2 are removed and the T-shaped plate 26 is pushed to slide at the same time, so that one T-shaped plate 26 is inserted into the two deflection seats 2, and then the T-shaped plate 26 is fixed to the deflection seat 2 with bolts. Before the two deflection seats 2 are connected, the drive ring 44 is first pushed to slide by a special tool, such as a U-shaped clamping rod, and the end of the U-shaped clamping rod is clamped into the clamping hole of the drive ring 44, and then the drive ring 44 is pushed to slide, so that the clamping block three 441 slides to the end of the clamping groove three 412. At this time, the drive ring 44 will push the push ring 414 to slide and press The spring 1 is compressed, and then the driving ring 44 is rotated to make the block 3 441 rotate to the engagement range of the bayonet 415, and then the U-shaped rod is loosened, so that the driving ring 44 slides under the action of the spring 1, so that the block 3 441 is engaged in the bayonet 415. During this process, the sleeve shaft 42 will slide out of the driving shaft 41, and the shaft rod 43 will slide into the driving shaft 41 and be fixed under the action of the driving ring 44. Then, one sleeve shaft 42 of the two transmission shaft kits 4 is engaged with the other shaft rod 43, so that the transmission shaft kits 4 in the two deflection seats 2 are connected together by transmission, that is, the two canal opening mechanisms 3 are connected by transmission, that is, one driving mechanism can drive all the canal opening mechanisms 3 to work, so that the fertilization work is more flexible, can be applied to fertilization in various terrains, and the fertilization effect is better; S5. After fertilization is completed, remove all components for easy transportation.

A method for applying liquid manure, using the liquid manure application device according to claim 9, characterized in that: The steps include: S1, connecting the connecting seat (1) to the mobile device, and connecting the driving shaft (41) to the external driving mechanism, and then driving the deflection seat (2) to rotate along the connecting seat (1) according to the fertilization needs, thereby raising or lowering the channel opening mechanism (3), thereby changing the channel opening depth; S2, driving the entire device to move by moving the moving parts, and driving the driving shaft (41) to rotate so that the canal opening mechanism (3) can open the canal, and transport the soil blocks generated during the canal opening process to both sides of the canal, and at the same time use the injection assembly (5) to inject liquid manure into the canal, and use the soil covering assembly (6) to refill the soil blocks on both sides of the canal into the canal after fertilization; S3. Choose single channel fertilization or multi-channel fertilization according to the fertilization terrain; S3.

1. When the terrain is narrow or complex, only one deflection seat (2), a channel opening mechanism (3), an injection assembly (5) and a soil covering assembly (6) are connected to the mobile device to carry out single channel fertilization; S3.

2. When the terrain is wide, multiple deflection seats (2), channel opening mechanisms (3), injection components (5) and soil covering components (6) are symmetrically installed on both sides of the deflection seat (2) on the basis of single-channel fertilization to perform multi-channel fertilization; S4, using the T-shaped plate (26) to fixedly connect the two deflection seats (2), and using the transmission shaft kit (4) to transmission-connect the plurality of channel opening mechanisms (3); S5. After fertilization is completed, remove all components for easy transportation.
