DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The utility model provides the following technical solutions: a spiral deep tiller, comprising a deep tiller body, the deep tiller body comprising a traction trolley 1, a deep tilling mechanism 2 and a boosting mechanism 3, a traction column 5 is installed on the top of the traction trolley 1, the deep tilling mechanism 2 is installed at the middle and rear end of the traction trolley 1, a boosting mechanism 3 is installed at the front end of the deep tilling mechanism 2, a support plate 9 is connected in the middle of the traction trolley 1, the bottom of the boosting mechanism 3 is pressed on the surface of the support plate 9, and the traction trolley 1 is connected to an external power device through the traction column 5. When the spiral deep tiller is in use, the entire traction trolley 1 is driven by an external power device, and the two spiral drill rods at the bottom of the deep tillage mechanism 2 are embedded into the bottom of the soil. Then, the external power device and the entire traction trolley 1 can be relied on to move to achieve a pulling effect on the deep tillage mechanism 2. During the movement, the second spiral drill rod 13 and the first spiral drill rod 12 are used to loosen the soil at the bottom in turn. In the process of loosening the soil, the booster mechanism 3 on the top of the traction trolley 1 is cooperated to control the entire deep tillage mechanism 2 to be pressed downward into the soil, so as to change the pressure applied by the deep tillage mechanism 2 during the deep tillage process and the overall deep tillage angle.

[0024] In this embodiment, the traction trolley 1 includes a frame 4 and a support column 7. Side plates 6 are installed on both sides of the frame 4. Both ends of the support column 7 are fixedly installed on the surface of the side plates 6. Two limit baffles 8 are provided on the surface of the support column 7. Wheels are installed at the bottom of the frame 4. The traction column 5 is fixedly installed on the surface of the frame 4. A gap is provided between the bottom of the support plate 9 and the ground. The traction trolley 1 at the bottom is connected to the external power equipment to drive and pull the entire device, and the entire deep loosening mechanism 2 is installed in the middle position of the traction trolley 1 to avoid re-pressing the soil after deep loosening.

[0025] Specifically, the traction trolley 1 is pressed against the ground by the wheels at the bottom, and the frame 4 supports the boosting mechanism 3 and the deep plowing mechanism 2 at the top as a whole. The boosting mechanism 3 is pressed against the surface of the support plate 9 by the hydraulic rod 17 at the bottom to push the deep plowing mechanism 2 at the rear end toward the gap below, thereby realizing the angle control process of the entire deep plowing mechanism 2. During the deep plowing operation, the loosened area can avoid being directly pressed by the traction trolley 1.

[0026] In this embodiment, the subsoiling mechanism 2 includes a transmission box 10, a first auger rod 12 and a second auger rod 13. A motor 11 is installed on the top of the transmission box 10. A driving shaft 18 and a driven shaft 21 are installed inside the transmission box 10. A driving gear 19 is installed on the surface of the driving shaft 18. A driven gear 20 is installed on the surface of the driven shaft 21. The driving gear 19 and the driven gear 20 are meshed. The top of the driven shaft 21 is embedded in the surface of the transmission box 10 through a bearing. The first auger rod 12 is fixedly installed at the end of the driving shaft 18. The second auger rod 13 is installed at the end of the driven shaft 21. The first auger rod 12 and the second auger rod 13 are arranged parallel to each other, and the length of the first auger rod 12 is greater than the length of the second auger rod 13. By providing two auger rods of different lengths, and drilling into the soil in sequence through the front and rear position settings for subsoiling processing, the resistance in the subsoiling process is effectively reduced, the difficulty of the work is reduced, and the efficiency of the subsoiling operation is improved.

[0027] Specifically, after starting the deep loosening machine, the motor 11 drives the driving shaft 18 to rotate, and the driving gear 19 on the driving shaft 18 drives the driven gear 20 to rotate, thereby controlling the second auger rod 13 on the driven shaft 21 to rotate. At this time, the first auger rod 12 and the second auger rod 13 can loosen the soil at the bottom at the same time, and through the two-stage loosening process, the loosening of the soil is more thorough.

[0028] In this embodiment, the booster mechanism 3 includes a transmission plate 16 and a hydraulic rod 17, the hydraulic rod 17 is fixedly mounted on the bottom of the transmission plate 16, an extension plate 14 is welded and mounted on the surface of the transmission box 10, a rotating sleeve 15 is fixedly mounted between the extension plate 14 and the transmission plate 16, the rotating sleeve 15 is sleeved on the surface of the support column 7, the limit baffle 8 rests on both ends of the rotating sleeve 15, two hydraulic rods 17 are provided, and the bottom of each hydraulic rod 17 is pressed on the surface of the support plate 9, and the top of the hydraulic rod 17 is embedded in the bottom groove of the transmission plate 16 through the connecting roller 22. The booster mechanism 3 at the top can flexibly control the tilting angle of the deep loosening mechanism 2, thereby further changing the angle between the two spiral drill rods in the deep loosening mechanism 2 and the soil, so that the depth and resistance of a single loosening can be adjusted, and the flexibility is higher.

[0029] Specifically, after the hydraulic rod 17 is started to extend, the transmission plate 16 can be lifted up through the connecting roller 22 embedded in the top of the transmission plate 16, and the middle rotating sleeve 15 rotates around the middle support column 7 through the above-mentioned lifting process, so that the extension plate 14 on the other side of the rotating sleeve 15 drives the entire transmission box 10 to press downward, and then the entire deep loosening mechanism 2 can be pressed downward toward the bottom, thereby increasing the pressure applied to the soil during the loosening process. At the same time, the purpose of controlling the downward pressure angle of the two spiral drill rods can also be achieved through the above-mentioned process.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
