An opening is provided at the upper part of the front side of the cart 1, and the opening is larger than the diameter of the auger 86, which is convenient for the auger 86 to drill the ground.

[0032] Embodiment 2, the difference from Embodiment 1 is that:

[0033] Please refer to Figure 1 , in the embodiment of the present invention, the drilling azimuth adjusting member 6 includes two first screws 61 respectively rotatably installed at two edges of the inner side surface of the cart 1. The output shaft of the first servo motor 5 is connected to one end of one of the first screws 61, and the other ends of the two first screws 61 are respectively rotatably connected to the rear sides of the two limiting plates 2. First transmission wheels 62 are fixedly provided on the outer parts of one ends of the two first screws 61.

Driven by the first transmission belt 63, the first transmission wheel 62 on the first screw 61 drives the other first screw 61 to rotate. The first screw 61 drives the nut block 64 to move. The adjusting plate 65 on the nut block 64 drives the concave frame 3 to rotate, so as to adjust the drilling angle of the auger 86.

[0034] Embodiment 3, the difference from Embodiments 1 and 2 is that:

[0035] Please refer to Figures 3-4 In the embodiment of the present invention, the disassembly device 87 includes a housing 871. The output shaft of the drilling motor 85 is fixedly connected to the upper part of the housing 871. Fixing plates 872 are arranged on both sides of the housing 871. An elastic arc plate 873 is arranged between one sides of the two fixing plates 872. The concave surface of the elastic arc plate 873 is fixedly connected to the housing 871 through a spring 874. Fixing blocks 875 are arranged on the opposite sides of the two fixing plates 872. The fixing blocks 875 slidably penetrate through one side of the housing 871. A positioning shaft 876 is arranged on one side of the fixing block 875. Positioning holes 861 adapted to the positioning shafts 876 are arranged on both sides of the upper end of the auger 86. The upper end of the auger 86 slidably penetrates through the lower part of the housing 871. When the elasticity of the elastic arc plate 873 is in a natural state, the two positioning shafts 876 are respectively clamped in the two positioning holes 861 on the auger 86. When installing the auger 86, under the elasticity of the elastic arc plate 873 and the spring 874, press the two elastic arc plates 873 to drive the two fixing plates 872 to move. The fixing plates 872 drive the positioning shafts 876 on the fixing blocks 875 to move, so that the distance between the two positioning shafts 876 is greater than the outer diameter of the upper end of the auger 86. Then insert the upper end of the auger 86 into the interior of the housing 871, and make the hexagonal hole 862 on the auger 86 catch on the hexagonal block 877. At the same time, align the positioning hole 861 on the auger 86 with the positioning shaft 876. After alignment, release the elastic arc plate 873. At this time, the fixing plate 872 will reset, and the positioning shaft 876 will insert into the positioning hole 861 on the auger 86, thus completing the installation work of the auger 86. When disassembling, in the same way, press the two elastic arc plates 873 to make the positioning shaft 876 disengage from the positioning hole 861 on the auger 86, and then pull the auger 86 out of the housing 871 to complete the disassembly work.

[0036] Please refer to Figures 3-4 In the embodiment of the present invention, a hexagonal hole 862 is arranged at the upper end of the auger 86. A hexagonal block 877 adapted to the hexagonal hole 862 is arranged on the top side inside the housing 871. The hexagonal block 877 is clamped inside the hexagonal hole 862. When installing the auger 86, the hexagonal block 877 will be stuck in the hexagonal hole 862 on the auger 86, playing a positioning role for the auger 86.

[0037] Embodiment 4 is different from Embodiments 1, 2, and 3 in that:

[0038] Please refer to Figures 5-6, in the embodiment of the present invention, the second lubricating and anti-jamming member 84 includes a storage shell 841 arranged at the upper part of one side of the substrate 83. A delivery pipe 842 communicating with its interior is provided at a corner on one side of the storage shell 841. The other end of the delivery pipe 842 is connected to an annular sleeve 843. A number of capillary tubes 844 are evenly arranged on the inner side of the annular sleeve 843. A channel cavity 848 is arranged inside the annular sleeve 843. Each capillary tube 844 and the delivery pipe 842 communicate with the interior of the channel cavity 848. A sponge pad 849 is fixedly arranged on the inner side of the channel cavity 848. The other end of each capillary tube 844 is connected to the sponge pad 849. A third screw 846 is horizontally rotatably installed inside the storage shell 841. A third servo motor 845 is installed at the rear of the storage shell 841. The output shaft of the third servo motor 845 is connected to one end of the third screw 846. A piston block 847 is screwed onto the outside of the third screw 846 through threads. The annular sleeve 843 is sleeved on the outside of the second screw 82. One end of each capillary tube 844 contacts the outer wall of the second screw 82. When lubrication is required for the second screw 82 or the first screw 61, lubricating oil is added to the storage shell 841, so that the third servo motor 845 drives the third screw 846 to rotate. The third screw 846 drives the piston block 847 to move. The piston block 847 squeezes the lubricating oil inside the storage shell 841. The lubricating oil enters the channel cavity 848 inside the annular sleeve 843 through the delivery pipe 842, and then wets the sponge pad 849. As the lubricating oil is continuously supplied, the lubricating oil flows out from each capillary tube 844 and flows towards the second screw 82 or the first screw 61. During the movement of the substrate 83, lubrication work is carried out on each position of the second screw 82, so that the substrate 83 will not get stuck during movement.

[0039] Working principle: Push the trolley 1 to the designated position. Then the first servo motor 5 drives the first screw 61 to rotate. Driven by the first transmission belt 63, the first transmission wheel 62 on the first screw 61 drives another first screw 61 to rotate. The first screw 61 drives the nut block 64 to move. The adjusting plate 65 on the nut block 64 drives the concave frame 3 to rotate, so as to adjust the drilling angle of the auger 86. After adjustment, the second servo motor 72 drives the second transmission wheel 71 to rotate. The second transmission wheel 71 drives another second transmission wheel 71 to rotate through the second transmission belt 73. The two second transmission wheels 71 respectively drive the two second screws 82 to rotate. The second screw 82 drives the substrate 83 to move. The drilling motor 85 drives the auger 86 at the lower part of the housing 871 to rotate, and the auger 86 performs drilling work;

[0040] When installing the auger 86, under the elasticity of the elastic arc plates 873 and the springs 874, press the two elastic arc plates 873 to drive the two fixing plates 872 to move. The fixing plates 872 drive the positioning shafts 876 on one side of the fixing blocks 875 to move, so that the distance between the two positioning shafts 876 is greater than the outer diameter of the upper end of the auger 86. Then insert the upper end of the auger 86 into the interior of the housing 871, and make the hexagonal hole 862 on the auger 86 snap onto the hexagonal block 877. At the same time, align the positioning hole 861 on the auger 86 with the positioning shaft 876. After alignment, release the elastic arc plate 873. At this time, the fixing plate 872 will reset, and the positioning shaft 876 will be inserted into the positioning hole 861 on the auger 86, thus completing the installation of the auger 86. When disassembling, use the same method to press the two elastic arc plates 873 to make the positioning shaft 876 disengage from the positioning hole 861 on the auger 86, and then pull the auger 86 out of the housing 871 to complete the disassembly work;

[0041] When it is necessary to lubricate the second screw 82 or the first screw 61, add lubricating oil to the storage case 841, so that the third servo motor 845 drives the third screw 846 to rotate. The third screw 846 drives the piston block 847 to move. The piston block 847 squeezes the lubricating oil inside the storage case 841. The lubricating oil enters the channel cavity 848 inside the annular sleeve 843 through the delivery pipe 842, and then wets the sponge pad 849. As the lubricating oil is continuously supplied, the lubricating oil flows out from each capillary tube 844 and flows towards the second screw 82 or the first screw 61. During the movement of the substrate 83, lubrication work is carried out on various positions of the second screw 82, so that the substrate 83 will not get stuck during movement.
