[0002] Deep plowing can break the bottom layer of the plow, increase the deep plowing layer, promote the healthy growth of crops, and improve the land's ability to store water and retain moisture and resist drought and waterlogging. It can improve the soil's aggregate structure, increase porosity, activate microbial populations, make the soil more loose, and further enhance fertility. It can turn the pests and pathogenic spores hidden underground to the surface, allowing birds to find food or be frozen to death, which helps to reduce the base number of overwintering insects and reduce the occurrence of insect pests in the next year. In addition, after deep plowing, pests will die of hypoxia, reduce the occurrence of diseases and pests, increase the organic matter content in the soil, and promote the elongation and lateral distribution of the root system, improve the root absorption capacity, break the bottom layer of the plow after deep plowing, enhance water absorption capacity, and once the root system is deep, the utilization rate of fertilizer is also higher, which improves the utilization rate of water, and at the same time can improve the soil's ability to store water and retain moisture, improve soil fertility, so deep plowing devices have broad development prospects.

[0029] In this embodiment, when the land needs to be turned over, the cutter 49 is inserted into the soil. During the turning process of the cutter 49, there may be impurities with higher hardness, such as stones, in the soil, which can easily damage the cutter 49, thereby increasing the cost, so a mechanism needs to be used for buffering. When the cutter 49 is impacted, the support column 48 will bend backwards due to the impact. At this time, the movable cylinder 42 will rotate, and the shock-absorbing rod 43 will also rotate and slide slightly into the movable cylinder 42. At this time, the shock-absorbing spring 44 will be compressed to absorb the shock, thereby preventing the support column 48 from bending backwards, thereby improving the safety of the device.

[0030] Example 2

[0031] like Figure 1-5 It is shown that on the basis of Example 1, the utility model provides a technical solution: preferably, the tool 49 includes a threaded tube 492 fixedly connected, the surface of the threaded tube 492 is threadedly connected with a locking nut 491, the inside of the threaded tube 492 is fixedly connected with a connecting column 493, the lower surface of the connecting column 493 is fixedly connected with a connecting plate 494, the lower surface of the connecting plate 494 is fixedly connected with a fixing plate 495, the inside of the fixing plate 495 is fixedly connected with a cutting tooth 497, and the side of the fixing plate 495 is threadedly connected with a locking screw 496.

[0032] In this embodiment, when the cutter 49 is damaged and needs to be replaced, when the entire tool 49 is damaged, the fixing nut 491 is screwed upwards, and then the connecting column 493 is removed for overall replacement. When only the tooth 497 is damaged, only the fixing screw 496 needs to be unscrewed, and the tooth 497 is removed from the fixing plate 495 for replacement, thereby reducing the cost of replacement and maintenance as much as possible and improving the convenience of the device.

[0033] Example 3

[0034] like Figure 1-5 It is shown that, based on Example 1, the utility model provides a technical solution: preferably, the adjustment mechanism 5 includes an adjustment plate 51 fixedly connected to the inside of the flip frame 3, an adjustment hole 52 is provided inside the adjustment plate 51, the adjustment plate 51 is slidably connected to the support frame 41, and a fixing pin 53 is inserted on the upper surface of the support frame 41, and the fixing pin 53 is adapted to the adjustment hole 52.

[0035] In this embodiment, when the width of the land to be turned over is not suitable, it is only necessary to pull out the fixing pin 53 in the turning frame 3, so that the support frame 41 can slide on the surface of the adjustment plate 51. After the support frame 41 slides to the appropriate adjustment hole, the fixing pin can be inserted back, thereby improving the applicability of the device.

[0036] The working principle of the soil deep plowing and returning to field device is described in detail below.

[0037] like Figure 1-5 As shown in the figure, when the soil needs to be turned over, the cutter 49 extends into the soil. During the turning over of the soil by the cutter 49, there may be impurities with high hardness such as stones in the soil, which can easily damage the cutter 49, thereby increasing the cost, so that a mechanism is needed for buffering. When the cutter 49 is impacted, the support column 48 is impacted and bends backward. At this time, the movable cylinder 42 rotates, and the shock absorbing rod 43 also rotates and slides slightly into the movable cylinder 42. At this time, the shock absorbing spring 44 is compressed to absorb shock, thereby preventing the support column 48 from bending backward. When the cutter 49 is impacted, the support column 48 is impacted and bent backward. At this time, the movable cylinder 42 rotates, and the shock absorbing rod 43 also rotates and slides slightly into the movable cylinder 42. At this time, the shock absorbing spring 44 is compressed to absorb shock, thereby preventing the support column 48 from bending backward. When it is damaged and needs to be replaced, when it is damaged as a whole, screw the locking nut 491 upwards, then remove the connecting column 493 and replace it as a whole. When only the tooth 497 is damaged, just unscrew the locking screw 496 and take out the tooth 497 from the fixing plate 495 for replacement. When the width of the land to be turned over is not suitable, just pull out the fixing pin 53 in the turning frame 3, so that the support frame 41 can slide on the surface of the adjustment plate 51. After the support frame 41 slides to the appropriate adjustment hole, the fixing pin can be inserted back.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
