[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0044] Example 1

[0045] like Figure 1As shown, this embodiment provides a drilling and tilling device, including a straw controller 1, a multi-functional drill bit 2, a power input component 3 and a driving mechanism. The straw controller 1 is mounted on the multi-functional drill bit 2, the power input component 3 is arranged on the top of the multi-functional drill bit 2, and the driving mechanism controls the rotation of the multi-functional drill bit 2 through the power input component 3.

[0046] like Figure 2 As shown, the straw controller 1 is cylindrical in shape as a whole, with an axial through hole 11. A limiting ring 13 is integrally provided in the through hole 11. The limiting ring 13 is arranged near the upper end of the straw controller 1. The straw controller 1 has multiple slag discharge holes 12, which are arranged in the upper middle part of the straw controller 1. The lower end of the straw controller 1 is provided with a blade 14, which facilitates the insertion of the straw controller 1 into the soil. A flange 15 is provided on the outer wall of the straw controller 1. In this embodiment, the lower portion of the straw controller 1 is threadedly engaged with the flange 15 of the straw controller 1. When the blade 14 is damaged, the lower portion of the straw controller 1 can be replaced.

[0047] like Figure 3 As shown, the multifunctional drill bit 2 is provided with a bearing 21, a retaining ring 22, a drill flower 23, a stone crushing drill tip 24, and a sawtooth 25. The stone crushing drill tip 24 is integrally arranged at the bottom end of the multifunctional drill bit 2 for crushing stones. The sawtooth 25 is arranged near the upper part of the stone crushing drill tip 24 to better cut the remaining root stubble. The lower end of the drill flower 23 is close to the stone crushing drill tip 24, and the upper end of the drill flower 23 extends above the slag discharge hole 12. The retaining ring 22 is arranged on the upper side of the bearing 21, and the bearing 21 is arranged above the limiting ring 13. The retaining ring 22 and the limiting ring 13 axially position the bearing 21. Figure 1 As shown, the multifunctional drill bit 2 is inserted into the straw controller 1, the drill flower 23 is fitted with the inner wall gap of the straw controller 1, and the lower end of the drill flower 23 extends out of the straw controller 1, so that the broken objects can gradually rise under the action of the drill flower 23 and be discharged from the slag discharge hole 12.

[0048] like Figure 4 As shown, the power input assembly 3 includes a bridge bearing assembly 31, a first bevel gear 32, and an internal retaining spring 33. The first bevel gear 32 is fixedly sleeved on the multifunctional drill bit 2 and is limited by the internal retaining spring 33. Figure 1 As shown, the driving mechanism can control the rotation of the multifunctional drill bit 2 via the first bevel gear 32 .

[0049] The method of using the drilling and tillage device is as follows: after controlling the multifunctional drill bit 2 to rotate through the driving mechanism, aim at the straw, press the multifunctional drill bit 2 or the straw controller 1 downward, so that the straw controller 1 and the multifunctional drill bit 2 move downward at the same time. Since the blade 14 is provided at the lower end of the straw controller 1, the straw controller 1 can be easily inserted into the soil. At this time, the straw is confined in the straw controller 1, and the high-speed rotating multifunctional drill bit 2 can drill the straw into pieces, and lift the broken materials (straw, stones, soil fragments, etc.) to the slag discharge hole 12 through the drill flower 23 and discharge them from the straw controller 1.

[0050] It should be noted that traditional twist drills can only drill preliminary holes and cannot completely crush the straw remaining in the soil. The main purpose of designing the cylindrical straw controller 1 is: after the crops are harvested, the straw remaining in the land can be controlled within the straw controller 1 during plowing. Under the high-speed rotation of the multi-functional drill bit 2, the remaining straw can be well crushed and returned to the field, becoming fertilizer for the next season's crops, creating conditions for high yields of the next season's crops.

[0051] Example 2

[0052] This embodiment provides a drilling and tilling system, which includes multiple drilling and tilling devices in Example 1, and also includes a pallet 4, an irrigation pipe 6, and a forklift 7.

[0053] like Figure 5 As shown, the tray 4 is a rectangular plate-like structure, with two rows of positioning holes 41 provided on the tray 4. The two rows of positioning holes 41 are symmetrically arranged along the central axis in the length direction of the tray 4. The spacing between two adjacent positioning holes 41 in each row of positioning holes 41 is equal. The straw controller 1 of the drilling and tilling device can be inserted into the positioning hole 41 and is fastened after being limited by the flange 15, thereby realizing simultaneous drilling of multiple drilling and tilling devices and uniform distribution of the drilling holes.

[0054] Multiple trays can be added in the horizontal and vertical directions according to the size of the regional plot to achieve the purpose of fast, efficient and accurate drilling, where the vertical direction is the direction perpendicular to the horizontal direction.

[0055] The tray 4 is also provided with an escape port 42, which is arranged around the positioning hole 41, so that some debris generated by the multi-function drill bit 2 during drilling can be discharged through the escape port 42. The tray 4 is provided with a plurality of visual windows along the central axis in the longitudinal direction of the tray 4, and a positioning sensor 43 and a limit sensor 44 are provided on the visual windows. The positioning sensor 43 is arranged at the midpoint of the line connecting two corresponding positioning holes 41 in the two rows of positioning holes 41. Tray beacon points 45 are provided on both sides of the positioning sensor 43. Two positioning sensors 43 and two limit sensors 44 are provided, and are respectively arranged near the two ends of the tray 4.

[0056] like Figure 7As shown, a battery pack 71, a lifting frame 72, and a supporting arm 73 are provided on the forklift 7. The lifting frame 72 is used to control the lifting and lowering of the supporting arm 73. A plurality of supporting arms 73 are provided, and one or more pallets 4 are fixedly provided on each supporting arm 73. A mounting opening corresponding to the size of the pallet 4 is provided on the supporting arm 73. The edge of the pallet 4 is fastened to the mounting opening of the supporting arm 73. The lifting and lowering of the pallet 4 is controlled by the lifting frame 72, thereby controlling the drilling of the drilling and tilling device. The battery pack 71 can power the forklift 7, the drive mechanism, the positioning sensor 43, and the limit sensor 44.

[0057] The fastening connection in this embodiment can be welding.

[0058] Irrigation pipes 6 are arranged parallel to the field, and multiple pipe beacon points 61 are evenly spaced along the pipes. In this embodiment, the pipe beacon points 61 are cross beacons. When the tray beacon points 45 on either side of the two positioning sensors 43 are aligned with the pipe beacon points 61, the operator can determine alignment based on the signals from the positioning sensors 43. At this point, the operator can activate the drive mechanism and control the downward movement of the lifting frame 72 to begin drilling. As the lifting frame 72 moves downward, the limit sensor 44 monitors the distance between the tray 4 and the irrigation pipe 6, preventing the tray 4 from descending too low and impacting the irrigation pipe 6.

[0059] In addition, a limit adjustment plate can be installed on the bottom surface of the support arm 73, and the limit adjustment plate is adjusted in height with screws. When the limit adjustment plate contacts the soil, the support arm 73 no longer moves downward, and the drilling depth can be fine-tuned.

[0060] It should be noted that when no irrigation pipe 6 is laid in the field, the spacing of the support arms 73 and the spacing of the positioning holes 41 on the tray 4 can be adjusted according to the row spacing and plant spacing required by crops such as corn, wheat, and rapeseed to adapt to the sowing requirements of different crops, so that the row spacing and plant spacing remain optimal.

[0061] like Figure 6 As shown, in this embodiment, the driving mechanism adopts a programming motor 5. The programming motor 5 has a programming function and can set different rotation speeds according to different soils, so that the rotation speed of the multifunctional drill bit 2 is different. The programming motor 5 can be fixedly set on the lifting frame 72. A transmission shaft 51 is fixedly set on the output shaft of the programming motor 5. A plurality of fixed bearings 52 are fixedly set on the transmission shaft 51. The transmission shaft 51 is fixed to the support arm 73 through the fixed bearings 52 (a bracket can be set on the support arm 73 to fix the fixed bearings 52 on the bracket). A plurality of second bevel gears 53 are also set on the transmission shaft 51. The plurality of second bevel gears 53 correspond one-to-one to the first bevel gears 32 of each row of drilling and tilling devices, so that the programming motor 5 can drive a row of drilling and tilling devices to work at the same time.

[0062] In this embodiment, a PLC controller is also provided on the forklift 7, and the PLC controller is respectively connected to the lifting frame 72, the programming motor 5, the positioning sensor 43, and the limit sensor 44. The PLC controller is used to control the lifting height of the lifting frame 72 and the speed setting of the programming motor 5. The PLC controller is also used to receive signals from the positioning sensor 43 and the limit sensor 44. The PLC controller can also receive position signals from Beidou navigation satellites to achieve the purpose of unmanned automated precision drilling.

[0063] It should be noted that the drilling and tillage system of the utility model can be used in conjunction with the Chinese utility model patent with authorization announcement number CN216821081U and patent name "Improved Water-Saving and Tillage-Free Precision Irrigation System" to achieve the purpose of precise drilling and precise irrigation.

[0064] That is, the embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
