As a specific implementation detail, as shown in fig. 2, the plow head 2 of the present embodiment includes a main body 201 and plow teeth 202, wherein the main body 201 is a columnar structure with a right trapezoid cross section, so that the plow head 2 has a certain gravity to better scoop up the soil, meanwhile, the plow teeth 202 are of a right triangular prism structure, the plow teeth 202 are uniformly spaced along the front side edge of the main body 201 to form a tooth-shaped structure, so as to better scoop up the soil, i.e. one of the right-angled surfaces of the plow teeth 202 is fixedly connected to the thinner side of the main body 201, the inclined surface of the main body 201 is a wavy curved surface 203 as shown in fig. 3, the wavy curved surface 203 includes a concave surface connected to the inclined surface of the plow tooth 202 and a convex surface facing the side of the rake part, the concave surface and the convex surface are integrally connected to form an S-shape, so that when plowing, the soil is firstly scooped up by the plow teeth 202 or the front side edge of the main body 201 between the plow teeth 202, compared with the structure that the pure body 201 without the plow teeth 202 is directly adopted as the plowshare 2, the cutting and plowing effect is better; and, the ploughshare 2 is above-mentioned wave curved surface 203 with the one side that lifts earth contact, can make earth when being shoveled by the ploughshare 2, just enter into sunken concave surface fast, and when the concave surface interior accumulation is more earth, just can gush towards the rear side top along the concave surface, then enter into the convex surface, because the protruding structure of convex surface, and naturally towards rear side steady movement again, then with high-speed rotatory staple 6 contact, thereby have sufficient time to be broken up, fall scattered. In order to enable the ploughshare 2 to cut into the soil better when starting to plough, the ploughshare 2 described above can also be designed as follows with reference to the construction shown in figures 4-5: do not establish foretell ploughshare 202, the design has lower cutting plate 27 and the last minute board 26 of bar instead, wherein, lower cutting plate 27 bottom has the blade and sets up towards the slope of below the front side, so as to insert in the soil layer fast, and go up minute board 26 and then be the structural style of twolip sword, one end rigid coupling is in the front side edge of main part 201, the other end pointed end is raised up towards the top of front side, make the earth that lower cutting plate 27 cut up in time by the last minute board 26 thorn piece that raises the setting, the separation of improvement earth, the crushing, the loose effect.

In the concrete preparation, as shown in fig. 1 and fig. 6, the ploughshare 2 articulates on frame 1 through the actuating arm 3 of a pair of relative setting, actuating arm 3 includes two arms of integrated into one piece's length difference, two arms intersect and are turning structure, two arms can intersect and form the member structure of L type, long arm 301 one end rigid coupling is in one of them side of ploughshare 2, its other end intersects with short arm 302 and articulates on frame 1 in crossing department, and the short arm 302 other end has an arc breach, so as to form the locking hook 3021 of arc type at its tip, the concave surface of locking hook 3021 is on the cylinder surface of pasting a spacing post 4, this spacing post 4 salient rigid coupling is on frame 1, thereby when ploughshare 2 antedisplacement lifts earth, combine the reaction force of earth and the dead weight of ploughshare 2, actuating arm 3 can be in the lock state, ensure the reliable and stable of structure. In the above design, in order to enable the driving arm 3 to be always relatively stable with the frame 1, a tension spring (not shown in the figure) fixedly connected to the frame 1 may be connected to the long arm 301 near a corner of the driving arm 3, for example, so that the tension spring always pulls up the long arm toward the side of the limit column, so that the short arm 302 may be fully and effectively in contact with the limit column. Here, one very critical design fit is: the radial clearance of the hinge joint between the driving arm 3 and the frame 1 can be slightly larger, so that when the plowshare 2 plows, the arc concave surface of the locking hook 3021 is fully attached to the cylindrical surface of the limiting column 4, the locking hook 3021 and the limiting column 4 are mainly in interference fit to bear force, and the driving arm 3 is also the reason that the driving arm 3 is arranged in a crutch-shaped structure, so that when the multifunctional machine works, the driving arm 3 and the hinge shaft 15 of the frame 1 are only mainly used for realizing the rotation of the driving arm 3, and can not be used as a main stress point to counteract the acting force of the plowshare 2 contacting with soil, and the hinge shaft 15 is ensured not to deform, thereby ensuring that the two driving arms 3 and the hinge shaft 15 of the frame 1 can be in the initial relative position, such as the coaxial position in a factory state, thereby ensuring that the plowshare 2 can not deflect along the axial two ends of the rotating shaft 5, and ensuring that the plowshare 2 and a raking part are always in a reasonable front-back opposite position relationship, the phenomenon of front and back dislocation can not occur. In order to prevent the driving arm 3 from being excessively lifted upwards or to prevent the plowshare 2 from jumping upwards to a large extent due to the plowshare 2 touching foreign matters such as stones during operation, a limiting element 28 is specially arranged on the frame 1 to prevent the long arm 301 of the driving arm 3 from excessively rotating upwards.

Of course, in actual operation, the plowing depth of the plowshare 2 and the softness of the corresponding soil may be greatly different, and at this time, it is preferable to be able to adjust the plowing depth of the plowshare 2, that is, to have a plowing depth adjusting gear, and to achieve this purpose, referring further to fig. 7-8, in this embodiment, the hinge shaft 15 between the driving arm 3 and the frame 1 is fixed on the frame 1, and the driving arm 3 is in rotational fit with the hinge shaft 15, that is, the driving arm 3 rotates around the hinge shaft 15 and the hinge shaft 15 does not rotate; a driven gear 16 is fixedly connected to the driving arm 3, the driven gear 16 is coaxially sleeved on the hinge shaft 15 in a rotating mode, the driven gear 16 is meshed with a driving gear 17 driven by a micro motor 18 to form speed reduction transmission, and the angle of the plowshare 2 cannot be adjusted to a great extent certainly, and cannot be rotated by 180 degrees or even 270 degrees in a short time, so that the micro stepping motor is preferably matched with the meshing transmission of a small gear and a large gear; of course, additional reduction gearboxes may be provided if desired. In addition, correspondingly, a plurality of limiting columns 4 are arranged, all the limiting columns 4 are arranged in an annular array around the center of the hinge shaft 15, all the limiting columns 4 are axially and elastically installed in the rack 1 in a telescopic manner, the end face of one end, exposed out of the rack 1, of each limiting column 4 is a convex smooth arc surface 401, and the cylindrical surface of each limiting column 4, opposite to the smooth arc surface 401, is used for being matched with the locking hook 3021 to tightly and tightly lock the driving arm 3 and bear the main load transmitted by the driving arm 3. When the depth of plowing at the inner end needs to be adjusted, for example, when the plowing is required to be shallower, the driving arm 3 should rotate clockwise, and then the outer side surface of the locking hook 3021 of the short arm 302 slides from right to left along the smooth arc surface 401 shown in fig. 8, so as to extrude the limiting posts 4 and press the limiting posts into the rack 1, so that the short arm 302 can slide over the corresponding limiting posts 4, be located between two adjacent limiting posts 4, and contact with one of the two adjacent limiting posts 4 in a collision manner, and when the proper depth of plowing by the plowshare 2 is reached, the micro motor 18 is turned off, and at this time, the locking hook 3021 of the short arm 302 stops between the two limiting posts 4 and abuts against the cylindrical side wall of the last limiting post 4 exposed out of the surface of the rack 1; on the contrary, when the plough depth is increased by shifting up, the corresponding limit column 4 is pressed back into the machine frame 1. In order to enable the locking hook 3021 and the limiting column 4 to be matched more tightly, an arc-shaped groove 402 can be annularly formed in the side surface of a cylinder at one end of the limiting column 4, which is exposed out of the rack 1, the bottom of the arc-shaped groove 402 is attached to the locking hook 3021, the other end of the limiting column 4 is installed in a blind hole of the rack 1 in a sliding fit manner and is abutted against a reset spring 20 at the bottom of the blind hole, a sliding block 19 is fixedly connected to the side wall of the limiting column 4, which is close to the other end of the limiting column, the sliding block 19 is in sliding fit with a sliding groove formed in the wall of the blind hole, the length of the sliding groove needs to enable the limiting column 4 to be completely immersed in the blind hole and not press the reset spring 20 to the limit when the reset spring 20 is extruded by the sliding block 19, and the reliability of plowing depth gear adjustment of the plough head 2 is greatly improved.

In order to realize the adjustment of the plowing depth more fully automatically, referring to fig. 8 together based on the above structure, an electromagnetic element 21 is embedded in the machine frame 1 below the blind hole in a facing manner, when the electromagnetic element 21 is electrified, the limit column 4 can be completely sucked back into the blind hole, and the electromagnetic element 21 is marked as number 1 and number 2. These electromagnetic elements 21 are respectively connected to a controller, and the control logic of the controller is: when the short arm 302 of the driving arm 3 needs to rotate from the current position-limiting post 4 to the target position-limiting post 4 counterclockwise, all the position-limiting elements 28 between the electromagnetic elements 21 corresponding to the current position-limiting post 4 and the target position-limiting post 4 are immediately powered off, and the electromagnetic elements 21 corresponding to the current position-limiting post 4 are also powered off simultaneously, so that the position-limiting post 4 corresponding to the corresponding gear can be in contact fit with the locking hook 3021. For example, when the depth of plowing is in the 3 rd gear, and the depth is increased to the 5 th gear, the 3 rd gear must be retracted into the frame 1, so the controller must switch on the power supply of the electromagnetic element 21 at the 3 rd gear to retract the electromagnetic element 21 into the frame 1, and at the same time, the electromagnetic element 21 at the 4 th gear must be retracted into the frame 1, so the controller must realize the circuit energization of the electromagnetic elements 21 at the 3 rd gear and the 4 th gear together.
