[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1: Please refer to Figure 1 - Figure 4 A liquid fertilizer fertilizing device with an adjustable diverter head inclination angle, comprising a carrier 1, a liquid storage tank 2 and a plurality of diverter heads 3, wherein the liquid storage tank 2 is mounted on the top of the carrier 1, a feeding port is arranged on the outer wall of one side of the liquid storage tank 2, and a sealing cover 24 is installed inside the feeding port;

[0036] Also includes:

[0037] A flow guiding mechanism is installed on the top of the carrier 1 and is used to establish a connection between the liquid storage tank 2 and the diverter head 3. The flow guiding mechanism includes a flow guiding pipe 4 installed at the bottom of the liquid storage tank 2 and a plurality of flow diverter components installed on the flow guiding pipe 4. The plurality of flow diverter components are respectively connected to the plurality of flow diverter heads 3. The flow diverter components include a hard pipe 5 and a metal hose 6. One end of the metal hose 6 is connected to the flow guiding pipe 4, and the other end of the metal hose 6 is connected to the hard pipe 5. The hard pipe 5 is an L-shaped structure. The lifting mechanism is provided with a plurality of groups. The hard pipe 5 is connected to the diverter head 3 through the lifting mechanism.

[0038] The liquid fertilizer in the liquid storage tank 2 flows out through the guide pipe 4, then flows into the hard pipe 5 through each metal hose 6, and then is discharged through the diverter 3. The arrangement of the metal hose 6 allows the hard pipe 5 to rotate normally.

[0039] A lifting mechanism, which is connected to the flow guide mechanism and the diverter head 3 respectively, and is used to adjust the height of the diverter head 3. The lifting mechanism includes a lifting pipe 7 that is slidably sleeved on the outside of the hard pipe 5 along the height direction thereof and a first screw sleeve 8 that is screwed on the outside of the hard pipe 5. The bottom end of the first screw sleeve 8 is rotatably connected to the top end of the lifting pipe 7, and the diverter head 3 is fixedly connected to the bottom end of the lifting pipe 7;

[0040] After the entire device is moved to the field, align each diverter head 3 with each fertilizer trench, and move it downward by rotating the first screw sleeve 8, thereby driving the lifting pipe 7 and the diverter head 3 to move downward, so that the diverter head 3 moves down to the inside of the fertilizer trench, and then when the carrier 1 moves and shakes left and right, the diverter head 3 remains inside the fertilizer trench.

[0041] An adjusting mechanism is installed on the top of the carrier 1 and is used to adjust the inclination angle of the diverter 3. The adjusting mechanism includes an adjusting shaft 9 rotatably connected to one side of the top of the carrier 1, a first gear 10 fixedly sleeved on the outside of the adjusting shaft 9, and a rack 11 slidably connected to the top of the carrier 1. The first gear 10 is meshed with the rack 11, and the rack 11 is connected to the compensation mechanism. The hard pipe 5 is rotatably connected to the inside of the adjusting shaft 9;

[0042] Since the hard tube 5 is rotatably connected to the inside of the adjusting shaft 9, when the carrier 1 moves and shakes, the diverter head 3 will always flow out the liquid fertilizer downwards due to the influence of its own gravity.

[0043] A compensation mechanism, which is installed on the top of the vehicle 1 and is used to drive the adjustment mechanism to operate when the vehicle 1 moves. The compensation mechanism includes a pillar 12 fixedly connected to the other side of the top of the vehicle 1, a balance plate 13 rotatably connected to the top of the pillar 12, a transmission tube 14 installed on the top of the vehicle 1, a first piston 15 installed inside the transmission tube 14 along the height direction, a driven rod 16 fixedly connected to the top of the first piston 15, a second piston 17 installed inside the transmission tube 14 along the horizontal direction, and a push rod 18 installed on the outer wall of one side of the second piston 17, the other end of the push rod 18 is connected to the rack 11, and the top of the driven rod 16 is rotatably connected to one side of the bottom of the balance plate 13. The compensation mechanism also includes four sealing cylinders 19 rotatably connected to the bottom of the balance plate 13, a third piston 20 installed inside the sealing cylinder 19, a lifting rod 21 fixedly connected to the bottom of the third piston 20, and a conical block 22 fixedly connected to the bottom end of the lifting rod 21, and two adjacent sealing cylinders 19 are connected by an oil guide pipe 23;

[0044] When the vehicle 1 moves on an uneven or uphill field, the vehicle 1 may tilt forward and backward. When this happens, the balance plate 13 is always kept in a horizontal state through the flow effect of the hydraulic oil in each sealing cylinder 19 and each oil guide pipe 23. That is to say, when the balance plate 13 tilts with the vehicle 1, the hydraulic oil in the sealing cylinder 19 will flow through the oil guide pipe 23 toward the sealing cylinder 19 on the tilted downward side, driving the third piston 20 in the sealing cylinder 19 to move downward, and the lifting rod 21 and the conical block 22 move accordingly, so that the balance plate 13 quickly returns to the horizontal state. In the process of the balance plate 13 returning to the horizontal state, the first piston 15 is driven to move through the driven rod 16, and then the second piston 20 is driven by the hydraulic oil in the transmission pipe 14. The plug 17 moves, and the push rod 18 drives the rack 11 to move accordingly, and the meshing effect between the rack 11 and the first gear 10 drives the adjusting shaft 9 to rotate, and then the angle of the diverter head 3 is adjusted through the hard tube 5, wherein, when the left end of the carrier 1 tilts upward, the diverter head 3 is driven to rotate upward to prevent the right end of the carrier 1 from tilting downward and causing the diverter head 3 to be inserted into the ground, resulting in obstruction of the movement of the carrier 1; when the right end of the carrier 1 tilts upward, the diverter head 3 is driven to rotate downward 3 to prevent the diverter head 3 from tilting upward and moving out of the fertilizer ditch when the right end of the carrier 1 tilts upward; at this time, when the carrier 1 shakes left and right again, it is easy to spill the fertilizer out of the fertilizer ditch; therefore, the fertilization effect of the liquid fertilizer is improved through the adaptive adjustment of the diverter head 3.

[0045] Example 2: Please refer to Figure 5 - Figure 6 , this embodiment provides a technical solution based on the embodiment 1: the liquid storage tank 2 is provided with a stirring mechanism, a pressing mechanism and a driving mechanism; the pressing mechanism includes two second screw sleeves 25 rotatably connected to the top of the liquid storage tank 2, a screw 26 screwed inside the second screw sleeve 25 and a sealing plate 27 installed inside the liquid storage tank 2, the bottom end of the screw 26 is fixedly connected to the top of the sealing plate 27, and one of the second screw sleeves 25 is connected to the driving mechanism; the two second screw sleeves 25 are connected to each other through a transmission member 28, and the transmission member 28 includes synchronous wheels fixedly sleeved on the outside of the two second screw sleeves 25 and synchronous belts connected to the outside of the two synchronous wheels;

[0046] The driving mechanism drives one of the second screw sleeves 25 to rotate, and the two second screw sleeves 25 are kept rotating synchronously through the transmission connection of the transmission member 28. When the driving mechanism drives the second screw sleeve 25 to rotate forward, the screw rod 26 is driven to move downward, and then the sealing pressing plate 27 is driven to move downward along the inner wall of the liquid storage tank 2, so that the liquid fertilizer inside the liquid storage tank 2 is evenly discharged;

[0047] When the second screw sleeve 25 is driven to reverse by the driving mechanism, the screw rod 26 is driven to move upward, and then the sealing pressing plate 27 is driven to move upward along the inner wall of the liquid storage tank 2, so as to add liquid fertilizer into the liquid storage tank 2.

[0048] The stirring mechanism includes a rotating drum 29 rotatably connected to the inside of the sealing plate 27, a plurality of stirring blades 30 fixed to the bottom of the rotating drum 29, a lifting shaft 31 fixed to the top of the rotating drum 29, and a driving sleeve 32 slidably sleeved on the outside of the lifting shaft 31, the driving sleeve 32 is rotatably connected to the top of the liquid storage tank 2, and the driving sleeve 32 is connected to the driving mechanism;

[0049] The driving sleeve 32 is driven to rotate by the driving mechanism, and the lifting shaft 31 rotates synchronously therewith. When the sealing pressure plate 27 moves up and down, the rotating drum 29 moves synchronously therewith, thereby driving the lifting shaft 31 to slide along the inner wall of the driving sleeve 32. Therefore, when the sealing pressure plate 27 is raised or lowered, the rotating drum 29 and the stirring blades 30 are driven to rotate synchronously, thereby achieving the effect of discharging and stirring at the same time.

[0050] The driving mechanism includes a motor 33 mounted on the top of the liquid storage tank 2, a second gear 34 fixedly sleeved on the outside of the output shaft of the motor 33, a third gear 35 fixedly sleeved on the outside of one of the second screw sleeves 25, and a fourth gear 36 fixedly sleeved on the outside of the driving sleeve 32, and the second gear 34 is meshed with the third gear 35 and the fourth gear 36 respectively;

[0051] The second gear 34 is driven to rotate by controlling the motor 33. The second gear 34 is meshed with the third gear 35 and the fourth gear 36 respectively, thereby driving the second screw sleeve 25 and the driving sleeve 32 to rotate respectively. The motor 33 can drive the second gear 34 to rotate forward or reverse.
