DETAILED DESCRIPTION

[0035] See also Figures 1 to 8 In an embodiment of the present invention, a liquid manure application device includes a connecting seat 1, a deflection seat 2, a channel opening mechanism 3, a transmission shaft set 4, an injection assembly 5 and a soil covering assembly 6, wherein the connecting seat 1 is rotatably provided with a deflection seat 2, two support plates 21 are obliquely fixedly provided on the deflection seat 2, the channel opening mechanism 3 is rotatably provided between the two support plates 21, the deflection seat 2 is rotatably provided with a transmission shaft set 4, the support plate 21 is rotatably provided with an injection assembly 5, and the deflection seat 2 is rotatably provided with a soil covering assembly 6;

[0036] The transmission shaft kit 4 includes a driving shaft 41, a sleeve shaft 42, a shaft rod 43 and a driving ring 44, wherein the sleeve shaft 42 is slidably arranged on the driving shaft 41, the shaft rod 43 is fixedly connected to the sleeve shaft 42, the diameter of the shaft rod 43 is smaller than the diameter of the sleeve shaft 42, and a connecting groove 421 of the same size as the shaft rod 43 is opened in the sleeve shaft 42, a driving ring 44 is slidably arranged in the driving shaft 41, the driving ring 44 is rotatably connected to the sleeve shaft 42 and the shaft rod 43, and a plurality of clamping holes are evenly opened on the driving ring 44.

[0037] In this embodiment, Figure 4 , Figure 5 and Figure 6 The connecting groove 421 is fixed with two strip-shaped blocks 422, and the shaft 43 is provided with two slots 431, and the blocks 422 can be inserted into the slots 431 and slide along the slots 431;

[0038] Two strip-shaped second clamping blocks 411 are fixedly disposed in the driving shaft 41 , and two second clamping grooves 423 are formed on the sleeve shaft 42 . The second clamping blocks 411 are clamped into the second clamping grooves 423 and slide along the second clamping grooves 423 .

[0039] During implementation, by setting the slot 1 431 and the block 1 422, when the two transmission shaft assemblies 4 are connected, the shaft 43 and the sleeve 42 can be engaged together and can rotate synchronously. The slot 2 423 and the block 2 411 are further set to enable the sleeve 42 and the drive shaft 41 to engage and rotate synchronously, so that when multiple transmission shaft assemblies 4 are connected together, they can rotate synchronously, that is, only one drive shaft 41 needs to be driven to rotate to make all the drive shafts 41 rotate together.

[0040] In this embodiment, Figure 4 , Figure 5 and Figure 6 Two clamping blocks 3 441 are fixedly arranged on the driving ring 44, a strip-shaped clamping groove 3 412 is opened in the driving shaft 41, an annular groove 413 is opened at the end of the clamping groove 3 412, a push ring 414 is slidably arranged in the annular groove 413, and a spring 1 is fixedly arranged between the push ring 414 and the annular groove 413, a bayonet 415 is opened on one side of the clamping groove 3 412, and the clamping block 3 441 slides along the clamping groove 3 412 and can be clamped into the bayonet 415.

[0041] In this embodiment, Figure 3 The channel opening mechanism 3 includes a rotating seat 31, a soil feeding plate 32 and a soil breaking block 33, wherein a rotating shaft 311 is fixedly arranged on the rotating seat 31, the rotating shaft 311 is connected to the driving shaft 41 through a chain transmission, the rotating shaft 311 is rotatably connected to the support plate 21, and a plurality of soil feeding plates 32 are fixedly arranged in a circle on the rotating seat 31, and a soil breaking block 33 is fixedly arranged at the output end of the soil feeding plate 32, and the soil breaking block 33 and the soil feeding plate 32 are both V-shaped arc plates.

[0042] In particular, the soil breaking block 33 and the soil delivery plate 32 are configured as V-shaped arc plates, so that during the trench opening process, the broken soil blocks can be transported out of the trench and pushed to both sides of the trench, thereby facilitating the soil covering component 6 to refill the soil blocks discharged from the trench.

[0043] In this embodiment, the injection assembly 5 includes a support rod 51, an injection rod 52 and a spacer plate 53. Among them, the support rod 51 is rotatably arranged on the deflection seat 2, and a first telescopic rod 22 is hinged between the support rod 51 and the deflection seat 2. The output end of the support rod 51 is fixedly provided with an injection rod 52. The injection rod 52 is connected to an external fertilizer supply mechanism through a hose. A guide plate 521 is fixedly arranged on one side of the injection rod 52 close to the canal opening mechanism 3. A V-shaped spacer plate 53 is slidably arranged on the guide plate 521, and the spacer plate 53 can be inserted into the ditch dug by the canal opening mechanism 3.

[0044] In addition, the power for the spacer plate 53 to slide along the guide plate 521 comes from an external driving mechanism, such as a hydraulic driving mechanism and a lead screw nut covering mechanism. And it is set that the spacer plate 53 can separate the canal opening mechanism 3 from the injection assembly 5 during the process of injecting manure, that is, the spacer plate 53 is stuck in the ditch to divide the ditch into two parts, namely the canal opening area and the injection area, to prevent the manure from flowing to the canal opening mechanism 3 through the ditch during injection, thus causing manure splashing. And the spacer plate 53 is V-shaped and inclined, and it can further transport the soil blocks in the ditch to the outside of the ditch and push them to both sides of the ditch. And during the process of pushing the soil blocks, the soil blocks will accumulate on one side of the spacer plate 53 facing its advancing direction, and then use the soil blocks to further fill the gap between the spacer plate 53 and the ditch, so that the liquid manure will not flow to the canal opening mechanism 3.

[0045] In this embodiment, the soil covering assembly 6 includes a bracket 61, an L-shaped support plate 62 and a soil covering plate 63. Among them, the bracket 61 is rotatably arranged on the support plate 21, and a second telescopic rod 23 is hinged between the bracket 61 and the deflection seat 2. Two L-shaped support plates 62 are fixedly arranged on the bracket 61. The output end of the L-shaped support plate 62 is fixedly provided with a deflection rod 621. A soil covering plate 63 is rotatably arranged on the deflection rod 621, and the two soil covering plates 63 are arranged in a V shape;

[0046] A cross bar 622 is fixedly arranged on the deflection rod 621. A deflection groove is formed in the soil covering plate 63. A rotating block 631 is fixedly arranged in the deflection groove. The cross bar 622 is rotatably connected to the rotating block 631. A plurality of second springs 632 are symmetrically arranged between the cross bar 622 and the deflection groove.

[0047] During implementation, when the deflection seat 2 rotates to adjust the ditch opening depth, the support 61 will rotate accordingly. At this time, the telescopic rod two 23 is used to drive the support 61 to further rotate along the deflection seat 2, thereby adjusting the position of the soil covering plate 63. At the same time, the soil covering plate 63 will deflect simultaneously, that is, the cross bar 622 will rotate along the rotating block 631, so that the soil covering plate 63 can always be in a horizontal position and can fit on the surface of the ditch, ensuring that the soil covering plate 63 can re-bury the soil blocks conveyed by the soil delivery plate 32 into the ditch, thereby reducing the volatilization of liquid manure and making the fertilization effect better.

[0048] In this embodiment, as Figure 8 , an arc-shaped T-shaped block 24 is fixedly arranged on the deflection seat 2, and an annular hydraulic rod 25 is fixedly arranged on the T-shaped block 24. An arc-shaped T-shaped groove 11 is formed in the connecting seat 1, and an annular hydraulic cavity 12 is formed on one side of the T-shaped groove 11. The annular hydraulic cavity 12 is connected to an external hydraulic driving mechanism. The T-shaped block 24 slides along the T-shaped groove 11, and the annular hydraulic rod 25 slides in a sealed manner along the annular hydraulic cavity 12.

[0049] In this embodiment, a T-shaped plate 26 is slidably arranged in the deflection seat 2. The T-shaped plate 26 penetrates through both ends of the deflection seat 2. A plurality of through holes are formed in the deflection seat 2, and the through holes penetrate through the T-shaped plate 26. Bolts are slidably installed in the through holes.

[0050] A method for applying liquid manure includes the following steps:

[0051] S1. Connect the connecting seat 1 to a mobile device. Among them, the mobile device has power, such as a tractor, an electric cart, etc., and drive the drive shaft 41 to be in transmission connection with an external driving mechanism. Subsequently, drive the deflection seat 2 to rotate along the connecting seat 1 according to the fertilization needs, thereby raising or lowering the ditch opening mechanism 3, so as to change the ditch opening depth;

[0052] In addition, when the deflection seat 2 rotates, the injection assembly 5 and the soil covering assembly 6 will rotate synchronously with the deflection seat 2. At this time, the telescopic rod one 22 and the telescopic rod two 23 can be used to further drive the support rod 51 and the support 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 leakage. And when the support 61 deflects, the soil covering plate 63 can deflect synchronously, so that the soil covering plate 63 can always be kept in the horizontal direction and fit on the top of the ditch, ensuring that the soil covering plate 63 can re-bury the soil blocks into the ditch;

[0053] S2. Drive the whole device to move by the movement of the moving part, and at the same time drive the drive shaft 41 to rotate so that the canal opening mechanism 3 opens the canal, and convey the soil blocks in the canal opening process to both sides of the canal. At the same time, use the injection component 5 to inject liquid manure into the canal, and use the soil covering component 6 to refill the soil blocks on both sides of the canal into the canal after fertilization;

[0054] Specifically, when opening the canal, the rotating seat 31 rotates clockwise and drives the soil conveying plate 32 and the soil breaking block 33 to rotate synchronously to perform the canal opening work. In this process, the soil breaking block 33 can break the soil blocks and convey the broken soil blocks to the soil conveying plate 32. The soil conveying plate 32 can rotate to take the soil blocks out of the canal, and the soil conveying plate 32 is V-shaped, so as to convey the soil blocks to both sides of the canal, which is convenient for the soil covering plate 63 to fill the canal;

[0055] S3. Select single-channel fertilization or multi-channel fertilization according to the fertilization terrain;

[0056] S3.1. When the terrain is narrow or complex, only connect one deflection seat 2, canal opening mechanism 3, injection component 5 and soil covering component 6 to the mobile device for single-channel fertilization;

[0057] S3.2. When the terrain is wide, symmetrically install multiple deflection seats 2, canal opening mechanisms 3, injection components 5 and soil covering components 6 on both sides of the deflection seat 2 on the basis of single-channel fertilization for multi-channel fertilization;

[0058] S4. Use the T-shaped plate 26 to fixedly connect the two deflection seats 2, and at the same time use the transmission shaft kit 4 to drive-connect multiple canal opening mechanisms 3;

[0059] Specifically, when selecting multi-channel fertilization, the deflection seat 2, the canal-opening mechanism 3, the injection assembly 5, and the soil-covering assembly 6 can be regarded as a whole. When connecting, only the two deflection seats 2 need to be fixedly connected, and the transmission shaft kit 4 in the deflection seat 2 needs to be drivingly connected. Among them, when the two deflection seats 2 are connected, remove the bolts on the deflection seat 2 and push the T-shaped plate 26 to slide at the same time, so that one T-shaped plate 26 is stuck into the two deflection seats 2. Then, use bolts to fix the T-shaped plate 26 to the deflection seat 2. And before the two deflection seats 2 are connected, first push the drive ring 44 to slide through a special tool, such as using a U-shaped clamping rod. Insert the end of the U-shaped clamping rod into the clamping hole of the drive ring 44. Then push the drive ring 44 to slide, so that the third clamping block 441 slides to the end of the third clamping groove 412. At this time, the drive ring 44 will push the push ring 414 to slide and compress the first spring. Then rotate the drive ring 44 so that the third clamping block 441 rotates into the clamping range of the clamping opening 415. Then release the U-shaped rod, so that the drive ring 44 slides under the action of the first spring, so that the third clamping block 441 is stuck into the clamping opening 415. During this process, the sleeve shaft 42 will slide out of the drive shaft 41, and the shaft rod 43 will slide into the drive shaft 41 and be fixed under the action of the drive ring 44. Then, clamp one sleeve shaft 42 in one of the two transmission shaft kits 4 with the other shaft rod 43, so that the transmission shaft kits 4 in the two deflection seats 2 are drivingly connected together, that is, the transmission in the two canal-opening mechanisms 3 is connected. That is, only one driving mechanism can be used to drive all the canal-opening mechanisms 3 to work, which makes the fertilization work more flexible, can be applied to fertilization in various terrains, and has a better fertilization effect;

[0060] S5. After the fertilization is completed, remove all the components to facilitate transportation.

[0061] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
