The extension direction of the beam 130 is perpendicular to the pulling direction of the plow 010. Optionally, the cross beam 130 is located between the reinforcement beam 140 and the oblique beam 120.

In the present embodiment, one end of the hydraulic cylinder 200 is connected to the middle of the cross member 130, so that the entire frame 100 is not unbalanced left and right when receiving the force of the hydraulic cylinder 200. Of course, in this embodiment, only a single hydraulic cylinder 200 is provided, and in alternative embodiments, the plow 010 may include more hydraulic cylinders 200 to provide more traction (or thrust). When a plurality of hydraulic cylinders 200 are included, the plurality of hydraulic cylinders 200 may be arranged uniformly on the cross member 130, or two hydraulic cylinders 200 may be connected to the first longitudinal member 110 and the second longitudinal member 112, respectively.

In this embodiment, the material of the frame 100 is steel or cast iron, and each of the longitudinal beams, the cross beams 130, the reinforcing beams 140, and the oblique beams 120 may be hollow or solid circular tubes.

FIG. 2 is a second perspective view of a plow 010 of an embodiment of the present application; fig. 3 is a third perspective view of the plow 010 of an embodiment of the present invention. Referring to fig. 1 to 3, in the present embodiment, the plowshare includes a first plowshare 300 and a second plowshare 310, the first plowshare 300 is disposed below the first longitudinal beam 110, and the second plowshare 310 is disposed below the second longitudinal beam 112. In the present embodiment, the two plowshares are spaced apart in the lateral direction, and the first plowshare 300 is located in front of the second plowshare 310 in the pulling direction of the plow 010. Therefore, the cultivated land area can be increased, the structure of the double-plowshare is uniformly and reasonably stressed, the depth of gully generated during cultivated land is uniform and consistent, the straightness is high, and the left and right unbalance cannot be caused.

In the embodiment, the first longitudinal beam 110 is provided with a first mounting part 301 extending downwards, the first mounting part 301 is provided with a plurality of vertically arranged mounting holes, and the first plowshare 300 is mounted in a part of the mounting holes on the first mounting part 301; the second longitudinal beam 112 is provided with a second mounting part 311 extending downwards, the second mounting part 311 is provided with a plurality of vertically arranged mounting holes, and the second plowshare 310 is mounted in a part of the mounting holes on the second mounting part 311.

Specifically, the first plowshare 300 is fixed to the first mounting portion 301 by means of bolts and nuts, and since the first mounting portion 301 has a plurality of mounting holes arranged vertically, the depth of the first plowshare 300 is adjustable. Similarly, the second ploughshare 310 is fixed to the second mounting portion 311 by means of bolts and nuts, and the depth of the second ploughshare 310 is adjustable. In order to ensure the stability of the plowshare, two bolts can be used for fixing one plowshare.

In the plow 010 shown in the drawings, since the hydraulic cylinder 200 is connected to the tractor at a position higher than the longitudinal beam and the tractor, the entire plow 010 can be lifted when the hydraulic cylinder 200 is retracted. When the depth of plowing needs to be deepened, the hydraulic cylinder 200 can be extended, so that the frame 100 of the plow tool 010 turns downwards, and the plowshare can dig deeper.

The depth of the plowshare in the process of operation can be convenient to control through the telescopic hydraulic cylinder 200.

It should be understood that in other embodiments of the present application, the hydraulic cylinder 200 may be attached to the underside of the cross member 130 as desired, and the hydraulic cylinder 200 may be attached to the tractor at a lower position than the longitudinal member to the tractor, such that the hydraulic cylinder 200 lowers the plow 010 when retracted and raises the plow 010 when the hydraulic cylinder 200 is extended.

In this embodiment, a limiting device 400 is further disposed on the frame 100, the limiting device 400 includes a liftable limiting wheel 410, and the limiting wheel 410 is used for abutting against the ground to limit the ploughing depth of the ploughshare. The spacing wheel 410 is connected with the frame 100 through a connecting rod 430, the connecting rod 430 is vertically disposed on the frame 100 and can be vertically adjusted in height, and the spacing wheel 410 is disposed at the lower end of the connecting rod 430. Specifically, the frame 100 may be provided with a mounting plate 420, the mounting plate 420 may be provided with a mounting hole, the connecting rod 430 may be provided with a row of connecting holes along a length direction, the connecting rod 430 may be mounted on the mounting plate 420 by a bolt or a positioning pin, and a height of the connecting rod 430 may be determined by selecting a corresponding connecting hole.

It will be appreciated that sudden resistance may be caused when the plowshare penetrates too deeply due to too much force (depression) applied by the hydraulic cylinder 200 or too loose soil. Through having set up stop device 400, can restrict the biggest depth of penetrating into the earth effectively. When the plowshare is going to penetrate into the ground too deeply, the limiting wheel 410 is firstly abutted to the ground, and the plough tool 010 is prevented from being pressed downwards continuously. Meanwhile, the limiting wheel 410 can roll, so that the advancing resistance of the cultivator is reduced.

The present embodiment provides a cultivator (not shown in the figures) comprising a tractor and the plow 010 of the previous embodiment, wherein the longitudinal beam of the plow 010 and the hydraulic cylinder 200 are both rotatably connected to the tail of the tractor. The tractor is used for providing traction to the plough tool 010, and the hydraulic cylinder 200 can control the plough tool 010 to be lifted or lowered integrally. The hydraulic device may be provided on a tractor and the corresponding steering assembly may be provided near the driving position for convenient operation.

The outer parcel of axis body between two rear wheels of tractor has the protecting crust (not rotating along with the axis body), and the position of protecting crust is less than the position of pulling the frame, and the one end of pneumatic cylinder 200 is rotated and is connected in pulling the frame, and the one end of longeron is rotated and is connected in the protecting crust.

The working principle of the plow 010 and the cultivator provided by the embodiment of the application is as follows:

when the cultivator is used for cultivating land, the hydraulic cylinder 200 is controlled to extend, the plowshare is inserted into the ground, and the tractor pulls the plough tool 010 to move forward, so that the cultivator enters a state of land cultivation operation. When the operation is finished, the hydraulic cylinder 200 is controlled to contract, the plough tool 010 is lifted, the plough head is separated from the ground, and then the cultivator can freely run.

In summary, the plow 010 of the embodiment of the present application includes a frame 100, a plow head connected to the frame 100, and a hydraulic cylinder 200. The frame 100 includes a longitudinal beam having one end for connection to a tractor and being vertically swingable relative to the tractor.
