A root-breaking and burying machine for tillage with slope change

Abstract

The application belongs to agricultural machinery and relates to a root stubble crushing and burying machine for fields with changing slopes, which comprises a shell, a dynamic and fixed knife stubble cutting device and a rotary burying machine. The dynamic and fixed knife stubble cutting device can observe the change of the field slope through a camera and feed back to a controller to control a spring positioning mechanism to adjust the length of the dynamic knife. When the sensor detects stubble, the nozzle on the dynamic knife is opened. The broken stubble can be precisely sprayed, and the telescopic mechanism synchronously drives the fixed knife to realize two-stage telescoping. The sawtooth-shaped fixed knife cooperates with the dynamic knife to complete the stubble crushing in the changing slope. The rotary burying machine is provided with a vibration motor on the rotary burying knife to prevent soil adhesion. The rotary tiller realizes automatic adjustment of the bending angle through the electric push rod, which can adapt to different slope environments. The controller controls the cylinder to realize the rotary burying knife into the soil depth adjustment, and the root stubble is buried and returned to the field.

This constitutes a stubble crushing and rotary burial machine that adapts to changes in farmland slope.

[0020] During operation, the tractor propels the implement forward via the three-point suspension frame 1. The moving blade power supply 4 supplies power to the stubble cutting blade motor 5, which drives the first gear 6 to rotate. The first gear 6 then drives the second gear 7 and gear shaft 4 to rotate in sequence. The gear shaft 4 drives the disc frame 8 to rotate, and the disc frame 8 drives the stubble cutting blade 27 to rotate. When working with stubble, the working length of the stubble cutting blade 27 remains unchanged. The slider rod 10 slides relative to the slide rail rod 11. At this time, the small power supply 17 of the spring positioning mechanism in the slider rod 10 supplies power to the small motor 16. The small controller 24 controls the small motor 16 to drive the eighth transmission shaft 18 to rotate. Compressed air enters the small air compressor 25 through the eighth pipeline 20. At this point, the small air compressor 25 drives the small cylinder 19 to push... The moving spring connecting plate 26 causes the end of the telescopic rod 23 to retract from the positioning hole of the sliding rod 11. During this process, the spring 22 is compressed. When the camera 94 observes a change in the slope of the cultivated land, and the length of the stubble cutting blade 27 needs to be changed, the camera 94 transmits a signal to the miniature controller 24 to control the miniature cylinder 19 in the spring positioning mechanism to stop moving, causing the spring 22 to reset. The end of the telescopic rod 23 is pushed into the positioning hole of the sliding rod 11. The sliding rod 11 rotates, pulling the disc slider 12 to move on the sliding groove of the disc frame 8. The disc slider 12 drives the other two disc sliders 12 to move synchronously through the synchronizing rod 15 and the synchronizing connecting slider 14. The spring positioning mechanism installed inside the disc slider 12 is controlled by the miniature controller 24. Similarly, the spring positioning mechanism installed inside the disc slider 12... In the spring positioning mechanism, one end of the telescopic rod 23 leaves the positioning hole on the side of the slide groove of the disc frame 8, and the disc slider 12 moves, thereby adjusting the working length of the cutting blade 27 fixed on the disc slider 12. When the miniature controller 24 calculates the working length of the cutting blade 27 corresponding to the slope, the spring positioning mechanism inside the disc slider 12 stops working, and the end of the telescopic rod 23 is inserted into the positioning hole on the side of the slide groove for fixation. At the same time, the spring positioning mechanism inside the slider rotating rod 10 starts working, causing the end of the telescopic rod 23 to retract from the positioning hole of the slide rotating rod 11, and the slider rotating rod 10 and the slide rotating rod 11 return to relative sliding. When the working length of the cutting blade 27 changes, the cutting fixed blade 59 needs to extend and retract synchronously, so that it can always cooperate with the cutting blade 27 to complete the support cutting. When the working length of the cutting blade 27 changes, the fixed blade power supply 58 in the fixed blade secondary telescopic mechanism supplies power to the fixed blade motor 55. The camera 94 observes the telescopic length of the cutting blade 27 and transmits the signal to the fixed blade controller 60 to control the fixed blade motor 55 to drive the screw 54 to rotate. The rotation of the screw 54 drives the slider frame 52 to rise and fall. The rise and fall of the slider frame 52 drives the first pulley 49 to rotate, which in turn drives the first belt 51 to rise and fall. The first belt 51 drives the lifting frame 57 to rise and fall. The rise and fall of the lifting frame 57 drives the second pulley 50 to rotate, which in turn drives the second belt 61 to rise and fall. The second belt 61 drives the fixed blade frame 53 to rise and fall. In this way, the telescopic length of the cutting fixed blade 59 on the fixed blade frame 53 and the lifting frame 57 is controlled respectively, thereby achieving the effect of two-stage telescopic movement of the cutting fixed blade 59.In the spraying mechanism, the spraying power supply 31 supplies power to the spraying motor 32. The spraying motor 32 drives the pump 34 to rotate via the fifth coupling 33. The liquid pesticide flowing through the pump 34 in the pesticide tank 35 is driven by the pump 34 to the nozzle 45 for spraying. The tenth power supply 47 supplies power to the tenth motor 46. The sensor 29 detects the stubble position and sends information to the fifth controller 48. The fifth controller 48 controls the tenth motor 46 to drive the fifth screw 41 to rotate. The fifth screw 41 drives the spraying slider bracket 42 to rise and fall, thereby pushing the hinge bracket 43 to change the spraying angle. During the stubble cutting process, the moving stubble cutter 27 and the fixed stubble cutter 59 work together to achieve precise spraying and rapid decomposition of the stubble. The camera 94 observes the terrain where the rotary burial cutter 76 is located and transmits the signal to the lifting controller 73, the vibration controller 81, and the push rod controller 92. The rotary burial power supply 97 supplies power to the rotary burial motor 64. The output shaft of the rotary burial motor 64 drives the rotary burial main shaft 62 to rotate via the coupling 63. The rotary burial main shaft 62 drives the rotary burial cutter 76 to rotate. The vibration controller 81 on the 76th floor controls the vibration power supply 79 to supply power to the vibration motor 82, causing the plastic cover 77 to vibrate. This reduces soil adhesion to the surface of the rotary tiller 76 while simultaneously burying the stubble. When the burying effect is poor and the bending angle of the rotary tiller 76 needs to be changed, the push rod power supply 89 supplies power to the electric push rod 91. The push rod controller 92 controls the electric push rod 91 to push the first connecting rod 87. The first connecting rod 87 then drives the second hinge 86 to rotate, thereby changing the bending angle. When the terrain slope changes, to ensure stable tillage depth, the lifting power supply 68 on the top plate of the outer casing 2 supplies power to the lifting motor 69. The lifting controller 73 controls the lifting motor 69 to rotate, which drives the first transmission shaft 71 to rotate via the tenth coupling 70, thereby driving the second air compressor 72 to rotate. The second air compressor 72 provides compressed air to the lifting cylinder 67. The lifting cylinder 67 and the bushing connecting frame 65 are fixedly mounted and move synchronously, controlling the lifting and lowering of the rotary tiller main shaft 62 to adjust the soil penetration depth of the rotary tiller 76.
