[0022] In this embodiment, with particular reference to Figure 1 ,Figure 2 、 Figure 6 and Figure 8 The lifting assembly 10 comprises a high-definition image sensor 1001 and a limiting support 1002, the high-definition image sensor 1001 is fixedly installed on the outer wall of the mounting bracket 8, the limiting support 1002 is fixedly provided with two groups and is located on the opposite side walls of the mounting bracket 5 respectively, the outer wall of the limiting support 1002 is fixedly installed with an electric control cylinder 1003, one end of the electric control cylinder 1003 is fixedly installed with a limiting guide rod 1004, the limiting guide rod 1004 is fixedly and slidably connected to the outer wall of the limiting support 1002, one end of the limiting guide rod 1004 is fixedly installed with a fixed seat 1005, and the outer wall of the fixed seat 1005 is rotatably connected with a moving wheel 1006.

[0023] The inner wall of the mounting shell 6 is fixedly installed with a conveyor 11, one side of the conveyor 11 and located on the opposite inner wall of the mounting shell 6 is fixedly installed with a straw crushing roller 12, one end of the straw crushing roller 12 penetrates through the mounting shell 6 and extends to the outer wall of the mounting shell 6 and is fixedly installed with a driving motor one 13, one side of the straw crushing roller 12 and located on the opposite inner wall of the mounting shell 6 is fixedly installed with a grid baffle 14, one side of the mounting shell 6 and located on the outer wall of the mounting bracket 5 is rotatably connected with a rotating rod 15, one end of the rotating rod 15 is fixedly installed with a cutting blade 16, and the other end of the rotating rod 15 is fixedly installed with a driving motor two 17, wherein the driving motor two 17 is fixedly installed on the outer wall of the mounting bracket 5, wherein the rotating rod 15 is fixedly provided with two groups and is located on the opposite outer walls of the mounting bracket 5 respectively, and the cutting blade 16 is located on one side of the conveyor 11.

[0024] Based on the above structural characteristics and the action of the connection relationship, the control panel 3 controls the agricultural machine 1 to operate, which makes the agricultural machine 1 move, at the same time, the control panel 3 controls the driving motor two 17 to operate, which makes the driving shaft of the driving motor two 17 drive the cutting blade 16 to rotate through the rotating rod 15, so that the cutting blade 16 cuts the straw, and then the cut straw falls on the outer wall of the conveyor 11, because the control panel 3 controls the conveyor 11 to operate, which makes the conveyor 11 transport the straw to move, at the same time, the control panel 3 controls the driving motor one 13 to operate, which makes the driving motor one 13 drive the straw crushing roller 12 to operate, which makes the straw crushing roller 12 crush the straw, at the same time, the grid baffle 14 blocks the crushed straw, and the crushed straw falls into the inner cavity of the fixed shell 703 through the grid baffle 14.

[0025] Based on the structural features and the role of the connection relationship, the driving end of the agricultural machine 1 drives the universal connecting shaft 702 to rotate, which drives the T-shaped gear box 701, and drives the two rotating shafts 704 on the outer wall of the rotating base 705, and then drives the driving belt pulley 706 at one end of the rotating shaft 704, which drives the two gear sets on the outer wall of the rotating shaft 704.

[0026] The bottom of the limiting stop lever 906 and the bottom of the cutting blade 16 are flush with each other, the grid baffle 14 is located on one side of the disc plow roller 708, the driving belt pulley 706 is fixedly provided with two groups and is located on the outer wall of the rotating shaft 704, and the control panel 3 is connected with the agricultural machine 1, the touch sensor 908, the audible and visual alarm 909, the high-definition image sensor 1001, the electric control cylinder 1003, the conveyor 11, the driving motor one 13 and the driving motor two 17 through wires, and is electrically connected, so that the device is powered on, and the control panel 3 controls the agricultural machine 1, the touch sensor 908, the audible and visual alarm 909, the high-definition image sensor 1001, the electric control cylinder 1003, the conveyor 11, the driving motor one 13 and the driving motor two 17 to operate.

[0027] When the straw returning and deep burying machine is working, the switch of the control panel 3 is turned on, and then the control panel 3 controls the agricultural machine 1 to operate, which makes the agricultural machine 1 move, and the control panel 3 controls the driving motor two 17 to operate, which drives the cutting blade 16 to rotate through the rotating rod 15, so that the cutting blade 16 cuts the straw, and then the cut straw falls on the outer wall of the conveyor 11. Because the control panel 3 controls the conveyor 11 to operate, the conveyor 11 transports the straw to move, and the control panel 3 controls the driving motor one 13 to operate, which drives the straw crushing roller 12 to operate, which crushes the straw, and the grid baffle 14 blocks the crushed straw, and the crushed straw falls into the inner cavity of the fixed shell 703 through the grid baffle 14.

[0028] By placing microbial inoculants or humic agents in the inner cavity of the storage tank 719, then opening the switch of the control panel 3, and then the control panel 3 controls the agricultural machine 1 to run, which makes the agricultural machine 1 move, and then the driving end of the agricultural machine 1 drives the universal connecting shaft 702 to rotate, which drives the T-shaped gear box 701, and then the T-shaped gear box 701 drives the two rotating shafts 704 on the outer wall of the rotating base 705 to rotate, and then one end of the rotating shaft 704 drives the driving belt pulley 706 to rotate, which drives the two gear sets to rotate. When one side of the driving belt pulley 706 rotates, it drives the driven belt pulley 713 through the transmission belt, which drives the fixed sleeve 707 to rotate, and the fixed sleeve 707 drives the driven gear 711 to rotate, and the two sets of driven gears 711 are connected by the connecting gear 712 to rotate synchronously, and then the fixed sleeve 707 rotates on the outer wall of the connecting sleeve 710, and the fixed sleeve 707 drives the disc plow roller 708 to plow and turn the soil, and the other side of the driving belt pulley 706 rotates, which drives the connecting belt pulley 717 to rotate through the transmission belt, which drives the conveying screw rod 714 to rotate, and the conveying screw rod 714 drives the positioning gear 715 to rotate, and the two sets of positioning gears 715 are connected by the limiting gear 716 to rotate synchronously, and then the conveying screw rod 714 rotates on the inner wall of the fixed sleeve 707. Since the microbial inoculants or humic agents in the inner cavity of the storage tank 719 fall into the inner cavity of the connecting sleeve 710 through the material guide shell 718, the conveying screw rod 714 conveys the microbial inoculants or humic agents, and the disc plow roller 708 plows the soil, and the microbial inoculants or humic agents flow out through the discharge hole 709 and are mixed with the soil and straw debris, thereby solving the problem that if the microbial inoculants or humic agents are not used after the straw is deeply buried, the decomposition period may be prolonged, affecting the planting of the next crop.

[0029] By opening the switch of the control panel 3, the control panel 3 controls the contact sensor 908 and the audible and visual alarm 909 to operate. When the agricultural machine 1 moves, the bottom of the limiting stop lever 906 and the bottom of the cutting blade 16 are flush with each other, which causes the limiting stop lever 906 to block the objects in front of the cutting blade 16. Since the straw plant is relatively soft, the blocking of the limiting stop lever 906 causes the straw to bend and tilt, and the straw will not be completely knocked down, so that the subsequent cutting blade 16 can cut. Only the tightness of the limiting spring 907 needs to be adjusted according to the needs. Since the straw is soft and will not exert a pushing force on the limiting stop lever 906, that is, the limiting stop lever 906 will not displace and touch the contact sensor 908. Similarly, when the metal foreign matter with hard texture contacts the limiting stop lever 906, the metal foreign matter exerts a reverse pushing force on the limiting stop lever 906, which causes the limiting stop lever 906 to rotate on the outer wall of the rotating shaft 904. At the same time, the limiting stop plate 905 stretches the limiting spring 907. When the limiting stop plate 905 touches the contact sensor 908, the contact sensor 908 generates an electrical signal which is conducted to the control panel 3 through a wire, so that the control panel 3 displays the foreign matter. When the set parameters are reached, the control panel 3 controls the audible and visual alarm 909 to issue an audible and visual warning to prompt the driver, thereby solving the problem that when the straw residue machine is working in the field, metal and other foreign matters are easily caused to damage the cutting tool, and the current equipment generally lacks an effective foreign matter detection system, and there is a safety risk when the cutting tool breaks and produces debris.

[0030] The high-definition image sensor 1001 can real-time display the ground environment at the bottom of the cockpit 2, which causes the high-definition image sensor 1001 to generate an electrical signal which is conducted to the control panel 3 through a wire, so that the control panel 3 can real-time display the picture. This is convenient for the driver to observe the deep burying effect of the crushed straw when the agricultural machine 1 moves. Only by opening the switch of the control panel 3, the control panel 3 controls the electric control cylinder 1003 to operate, so that one end of the electric control cylinder 1003 pushes the fixed seat 1005 through the limiting guide rod 1004, which causes the fixed seat 1005 to drive the moving wheel 1006 to abut against the ground, and the limiting support 1002 drives the installation support 5 to adjust the height, so that the installation support 5 drives the disc harrow roller 708 of the deep burying assembly 7 to adjust the height, so that the deep burying depth of the disc harrow roller 708 can be adjusted at any time, thereby solving the problem of insufficient deep burying depth adjustment accuracy of some models, which causes the straw burying depth to be inconsistent, affects the decomposition efficiency, and the problem of over-shallow straw being easily eroded by wind or the ground being dry, and over-deep straw delaying decomposition.

[0031] The agricultural machine 1, the contact sensor 908, the audible and light alarm 909, the high-definition image sensor 1001, the electrically controlled cylinder 1003, the conveyor 11, the driving motor one 13, the driving motor two 17 and the control panel 3 used in the present application are all known electrical devices and can be directly purchased and used in the market, and their structures, circuits and control principles are all known technologies, therefore, the structures, circuits and control principles of the agricultural machine 1, the contact sensor 908, the audible and light alarm 909, the high-definition image sensor 1001, the electrically controlled cylinder 1003, the conveyor 11, the driving motor one 13, the driving motor two 17 and the control panel 3 will not be described here.
