[0037] The power chassis 1 is equipped with a control module, a fertilizer tank 7, two automatic variable fertilizer discharge systems 8 and two fixed-point fertilizer application systems 9, with the two automatic variable fertilizer discharge systems 8 and the two fixed-point fertilizer application systems 9 being set up one-to-one;
[0038] The automatic variable discharge fertilizer system 8 includes a photoelectric sensor 44, a soil conductivity meter 10, a variable discharge fertilizer mechanism, and a hydraulic cylinder 11. The variable discharge fertilizer mechanism includes a housing 12, with a fertilizer inlet 13 at the top and a fertilizer discharge connector 14 connected to the bottom.

The housing 12 is fixed to the bottom of the fertilizer tank 7, and the fertilizer inlet 13 at the top of the housing 12 is aligned with the fertilizer discharge port of the fertilizer tank 7. A motor mounting component 15 is fixed on the housing 12 for mounting a stepper motor 16. Two circular holes 17 are correspondingly opened on opposite side walls of the housing 12. The center line of the circular hole 17 is the center line of the outer shell 12. A grooved wheel body 18 is rotatably installed inside the outer shell 12. The grooved wheel body 18 is arranged along the center line of the outer shell 12. The grooved wheel body 18 has a number of fertilizer storage grooves 19. The stepper motor 16 is used to drive the grooved wheel body 18 to rotate. The specific transmission structure is as follows: a splined shaft 20 is rotatably installed on the motor mounting part 15. The main shaft of the stepper motor 16 is connected to the splined shaft 20 through a coupling 21. The grooved wheel body 18 has a splined hole body 22. The splined shaft 20 extends into the splined hole body 22. The stepper motor 16 can drive the grooved wheel body 18 to rotate through the splined shaft 20.
[0039] A blocking wheel cover plate 23 is provided at the end of the grooved wheel body 18. The blocking wheel cover plate 23 has an irregular hole 24. The irregular hole 24 is the same as the vertical section of the grooved wheel body 18. The vertical section is perpendicular to the axis of the grooved wheel body 18. The blocking wheel cover plate 23 is fitted onto the end of the grooved wheel body 18 through the irregular hole 24. The blocking wheel cover plate 23 can move along the grooved wheel body 18. A blocking wheel 25 is provided in the circular hole 17 of the outer shell 12. The blocking wheel 25 and the stepper motor 16 are located on opposite sides of the outer shell 12. The blocking wheel 25 has an open cavity 26. The cavity 26 of the blocking wheel 25 faces the blocking wheel cover plate 23. The blocking wheel cover plate 23 is rotatably mounted on one end of the blocking wheel 25. The push rod end of the hydraulic cylinder 11 is connected to the other end of the blocking wheel 25.
[0040] The photoelectric sensor 44, soil conductivity detector 10, stepper motor 16 and hydraulic cylinder 11 are respectively connected to the control module. The soil conductivity detector 10 is used to detect soil conductivity information in real time. The control module processes this information into the amount of fertilizer required by the soil, and then controls the hydraulic cylinder 11. The hydraulic cylinder 11 pushes the blocking wheel 25 to change the amount of fertilizer stored in each fertilizer storage wheel groove 19, and finally realizes the adjustment of the amount of fertilizer applied to each plant.
[0041] like Figure 10As shown, the fixed-point fertilization system 9 includes a rectangular fertilizer pipe 27 and an intermittent drive component. The rectangular fertilizer pipe 27 is fixed to the bottom of the power chassis 1 and is located between the soil cover 6 and the furrow opener 5. The upper end of the rectangular fertilizer pipe 27 is connected to the fertilizer drop connector 14 of the outer shell 12 through the fertilizer delivery pipe 28. Two fertilizer drop blocks 29 are provided inside the rectangular fertilizer pipe 27. The two fertilizer drop blocks 29 are symmetrically arranged. The upper ends of the two fertilizer drop blocks 29 are respectively hinged to the inner wall of the rectangular fertilizer pipe 27 through pins 30. A V-shaped fertilizer storage cavity 31 is formed between the upper parts of the two fertilizer drop blocks 29. The lower parts of the two fertilizer drop blocks 29 are close to each other. The intermittent drive component is used to drive the two fertilizer drop blocks 29 to rotate around the pins 30, and the two fertilizer drop blocks 29 rotate in opposite directions around the pins 30.
[0042] The intermittent drive unit includes a drive shaft 32 and a drive unit 33. The drive shaft 32 is rotatably mounted on the bottom of the power chassis 1. The front wheel 2 is connected to the drive shaft 32 through a sprocket and chain drive pair 34. The drive shaft 32 has a worm section 35. The bottom of the power chassis 1 is fixed with a mounting plate. A rotating shaft 36 is rotatably mounted on the mounting plate. One end of the rotating shaft 36 is provided with a worm wheel 37. The worm wheel 37 meshes with the worm section 35 on the drive shaft 32 for transmission. The other end of the rotating shaft 36 is provided with an eccentric wheel 38.
[0043] Two long slots 39 are opened on the wall of the rectangular fertilizer pipe 27. The long slots 39 are set in the vertical direction. The side walls of the two fertilizer drop blocks 29 are each opened with a slanted slot 40. The two slanted slots 40 form a figure-eight structure. The two slanted slots 40 correspond to the two long slots 39. The lower part of the driving component 33 is provided with two sliding pillars 41. The two sliding pillars 41 pass through the two long slots 39 and extend into the two slanted slots 40 respectively. The upper part of the driving component 33 is provided with an elongated oval limiting hole 42. The elongated oval limiting hole 42 is set in the horizontal direction. An eccentric cylinder 43 is fixed at the eccentric part of the eccentric wheel 38. The eccentric cylinder 43 is located in the elongated oval limiting hole 42.
[0044] In addition, the automatic variable fertilizer discharge system 8 can be upgraded to have a forced fertilizer discharge function, which can fully discharge the fertilizer on the groove wheel body 18. The specific settings are as follows: the groove wheel body 18 has a central hole, the central hole of the groove wheel body 18 is a stepped hole, the stepped hole is composed of a through hole body 45 and a spline hole body 22, and the spline shaft 20 extends into the spline hole body 22 after passing through the through hole body 45.
[0045] One end of the grooved wheel body 18 has an annular end cap 46, and the blocking wheel cover plate 23 is located at the other end of the grooved wheel body 18. Each fertilizer storage groove 19 of the grooved wheel body 18 has an installation notch 47. The installation notch 47 is arranged along the axial direction of the grooved wheel body 18. A forced fertilizer discharge plate is arranged in the installation notch 47. The forced fertilizer discharge plate includes a swing plate 48 and an adjusting plate 49. The adjusting plate 49 has a slot 55. The swing plate 48 is inserted into the slot 55 of the adjusting plate 49. The end of the swing plate 48 is mounted on the annular end cap 46 by a spring plunger 50, and the swing plate 48 can rotate around the spring plunger 50. The end of the adjusting plate 49 is mounted on the blocking wheel cover plate 23 by a half-tooth bolt 51, and the adjusting plate 49 can rotate around the half-tooth bolt 51. The axes of the spring plunger 50 and the half-tooth bolt 51 coincide.
[0046] The swing plate 48 is an L-shaped plate, with half of the swing plate 48 extending into the through hole 45 of the groove wheel body 18. A stop rod 52 is fixed on the motor mounting part 15. The stop rod 52 passes through the round hole 17 on the outer shell 12 and extends into the through hole 45 of the groove wheel body 18. When the groove wheel body 18 rotates, the stop rod 52 collides with half of the swing plate 48. Due to the movement of the stop rod 52, the swing plate 48, together with the adjusting plate 49, swings around the spring plunger 50 and the half-threaded bolt 51. During the swing, the fertilizer in the fertilizer storage wheel groove 19 is forcibly discharged. In addition, a return spring 53 is connected between half of the swing plate 48 and the inner wall of the through hole 45 of the groove wheel body 18. When the swing plate 48 swings, the return spring 53 is compressed. After the swing, the swing plate 48 and the adjusting plate 49 return to their original positions under the elastic force of the return spring 53.
[0047] Furthermore, a navigation camera 54 is installed at the front of the power chassis 1, and the navigation camera 54 and the drive motor 4 are respectively connected to the control module signal.
[0048] The forced-discharge fixed-point fertilization robot of the present invention drives the front wheel 2 to rotate via the drive motor 4, and the power chassis 1 moves forward. It identifies the path through the navigation camera 54 and autonomously walks between the rows of crops in the field. For open-field vegetables, the photoelectric sensor 44 identifies the crops and transmits the signal to the stepper motor 16. The stepper motor 16 drives the groove wheel body 18 to rotate to realize fertilizer discharge. In addition, the soil conductivity detector 10 detects the soil conductivity in real time and converts the required amount of fertilizer information in real time. Then, the control module controls the hydraulic cylinder 11, which pushes and pulls the blocking wheel 25 to adjust the amount of fertilizer stored on the groove wheel body 18 to the amount of fertilizer required for each vegetable. The swing plate 48 and the adjustment plate 49 on the groove wheel body 18 swing rapidly under the operation of the stop bar 52, thereby realizing the forced and rapid discharge of fertilizer in the fertilizer storage wheel groove 19. The discharged fertilizer falls into the V-shaped fertilizer temporary storage cavity 31 inside the rectangular fertilizer pipe 27 through the fertilizer delivery pipe 28.
[0049] Meanwhile, the front wheel 2 drives the drive shaft 32 to rotate through the sprocket and chain transmission pair 34. The drive shaft 32 drives the worm wheel 37 to rotate through the worm section 35. The rotating shaft 36 follows the rotation of the worm wheel 37, thereby rotating the eccentric wheel 38, which in turn drives the drive component 33 to move up and down reciprocally. The lower part of the drive component 33 cooperates with the inclined slot 40 on the fertilizer drop block 29 through two sliding pins 41, so that the two fertilizer drop blocks 29 open, and the fertilizer in the fertilizer storage chamber 31 can fall into the ditch opened by the ditch opener 5. Then, the soil is covered by the soil coverer 6, and then the compaction wheel 3 compacts it. It should be noted that the transmission ratio of the sprocket and chain transmission pair 34 and the worm wheel 37 and the worm section 35 is calculated and takes the plant spacing of open field vegetables as a reference to ensure that each time the fertilizer drop block 29 is opened, it is at a fixed point position for each vegetable, so as to realize the fixed point fertilization operation.
