[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] like Figure 1-8 As shown, the deep tillage machine of this embodiment includes: a front plow group 20 and a rear knife group 30 arranged front and back, the front plow group 20 includes at least one deep tillage plow 21, the rear knife group 30 includes at least one knife head 31, the knife head 31 includes a laterally rotatable knife disc 32, and at least one knife blade 33, the top end of the knife blade 33 is connected to the knife disc 32, and the bottom end of the knife blade 33 is downward.
[0031] The utility model is designed with a cutter disc 32 that can rotate horizontally and a blade 33 that extends longitudinally. The bottom end of the blade 33 can extend into a very deep soil layer and stay in the very deep soil layer to continuously rotate and crush the soil. The blade 33 is provided with a spacing relative to the rotation axis of the cutter disc 32. When the blade is driven by the cutter disc to rotate, a movement similar to stirring and breaking soil blocks is formed, so that the soil blocks that have been deeply plowed by the deep loosening plow are more easily broken by the blade, such as Figure 7 , 8 As shown, driven by the cutter disc 32, the blade 33 rotates around the rotation axis of the cutter disc 32 at a certain distance from the rotation axis to perform rotational breaking of the soil. During normal deep plowing and loosening, the lower end of the blade 33 is always buried under the soil layer to rotate and break the soil, and the load it bears is relatively stable, avoiding frequent exposure of the soil layer upward and then penetrating into the soil layer downward to cause load impact on the blade 33.
[0032] In addition, the front deep loosening plow 21 first deeply plows and loosens the soil layer, and then the rear cutter head 31 rotates to crush the soil clods. This not only deeply plows and loosens the cultivated land to make the soil more fluffy, but also reduces the stress on the cutter head 31, greatly reduces the shock of core components, and improves the problems of excessively high operating temperature of the transmission system and easy damage to the transmission parts and the cutter head 31.
[0033] Preferably, more than two deep tillage plows 21 are arranged in a row, and more than two cutter heads 31 are arranged in a row to form a two-layer rake tooth structure, so as to better rake the land, and the cutter heads 31 rotate and break the soil to achieve uniform and effective deep tillage and loosening; in this embodiment, if Figure 5 As shown, the front plow group 20 includes two deep loosening plows 21 , and the rear cutter group 30 includes four cutter heads 31 .
[0034] The cutter head 31 includes at least two blades 33, and the blades 33 on two adjacent cutter heads 31 are staggered. In this embodiment, the cutter head 31 includes two blades 33, and the blades 33 on two adjacent cutter heads 31 are staggered. Figure 6 As shown in FIG. 1 , the blade "crossing" means that the motion trajectories of the blades 33 of two adjacent blade heads 31 partially overlap or cross, and the blade "staggered" means that the blades 33 of adjacent blade heads 31 successively pass through the overlapping or intersecting motion trajectories. Moreover, the blades 33 on each blade head 31 are staggered with each other, and when rotating, only one blade 33 of a blade head 31 is located at the front end to contact the soil line, such as Figure 6 As shown, in the forward direction of the deep tillage scarifier, the soil line to be broken will be encountered. In this embodiment, the blades 33 are staggered so that only one blade 33 is located at the front end of the entire rear blade group 30 at the same time and first contacts the soil line to break the soil blocks, so that more power can be used to break the soil blocks, and the breaking efficiency is high. Figure 6 As shown, the phase of the blade 33 of the first cutter head 31 from the left is 45°, the phase of the blade 33 of the second cutter head 31 is -67.5°, the phase of the blade 33 of the third cutter head 31 is 22.5°, and the phase of the blade 33 of the fourth cutter head 31 is -45°. The rotation directions of the two adjacent cutter heads 31 are opposite, and the blades 34 of the blades 33 of the two adjacent cutter heads 31 are installed in opposite directions accordingly, which can form a scissor-like shearing effect on the soil blocks, and can better break the soil blocks. However, it is not limited to this embodiment, and can be designed according to the spirit of the utility model as a combination of blades and cutter heads with different numbers of cutter heads, different numbers of blades, other angles, other forms, and other rotation directions.
[0035] In this embodiment, the blades 33 of each cutter head 31 are staggered at an angle, so that during deep plowing and loosening operations, as few blades 33 as possible hit the soil layer at the same time, so that the shock occurs more evenly in each cutter head 31 in sequence, avoiding multiple rake teeth from being subjected to resistance at the same time and causing severe overall shock.
[0036] A blade 34 is provided on the side of the blade 33, and the blade 34 is located at the front end of the rotation direction of the blade 33. The bottom end of the blade 33 is inclined and extends forward in the rotation direction of the blade 33, presenting a posture of slightly upwardly attacking the soil block, which can better cut the soil block.
[0037] The present embodiment further includes a suspension bracket 10, which is used to mount the deep tillage scarifier on the tractor, and includes a lower bracket 12 and an upper bracket 11 mounted on the lower bracket 12, and the front plow group 20 and the rear blade group 30 are mounted on the lower bracket 12.

The reducer 14 is used to drive the cutter head 31 to rotate, and the subsoil plow 21 and the cutter head 31 are installed at the bottom of the platform 13.
[0039] The upper bracket 11 or the lower bracket 12 is provided with a cantilever 41 and a slot 42. In this embodiment, the lower bracket 12 is provided with two cantilevers 41 and two corresponding slots 42, and the first end of the cantilever 41 is movably inserted into the slot 42. Figure 4 As shown, an upper and lower movable gap 43 is provided between the upper and lower sides of the first end of the cantilever 41 and the slot 42, and a hanging point 16 is provided at the second end of the cantilever 41. The hanging point 16 is used to be mounted on a tractor, and the cantilever 41 swings up and down in the slot 42 to filter some vibrations and reduce the impact on the cutter head 31.
[0040] The cantilever 41 is also provided with a latch 44 , a plug hole 46 is provided on the side wall of the slot 42 , and a positioning hole 45 is provided on the cantilever 41 . The latch 44 is inserted into the plug hole 46 and the positioning hole 45 ; the latch 44 plays a positioning role and serves as a rotating shaft for the cantilever 41 to swing.
[0041] In this embodiment, the side wall of the slot 42 is provided with at least two insertion holes 46 arranged at intervals, and the plug 44 can be matched with any of the insertion holes 46. The insertion depth of the cantilever 41 is adjusted, thereby adjusting the length of the hanging point 16 of the lower hanger 12, and adjusting the depth or angle of the cutter head 31 into the soil. Not limited to this embodiment, it can also be designed that the cantilever 41 is provided with at least two positioning holes 45 arranged at intervals, and the plug 44 can be matched with any of the positioning holes 45.
