The hydraulic cylinder 3 includes a cylinder 31 and a piston rod 32. The plow frame 2 is rotatably arranged on the suspension bracket 1 around a horizontal axis, the cylinder body 31 of the hydraulic cylinder 3 is hinged with the suspension bracket 1, the piston rod 32 of the hydraulic cylinder 3 is hinged with the plow frame 2, when the plow frame 2 rotates to a horizontal position, the support plate 11 is positioned below the plow frame 2, and the distance from the support plate 11 to the horizontal axis is greater than the distance from one end of the plow frame 2 in the width direction to the horizontal axis and less than the distance from the other end of the plow frame 2 to the horizontal axis. Wherein, as shown in fig. 4, the right side wall of the plow frame 2 is provided with a second rotating shaft 29, as shown in fig. 3, the lower middle position of the suspension frame 1 is provided with a second shaft hole 13, and a bearing is arranged in the second shaft hole 13, and the rotatable connection of the plow frame 2 and the suspension frame 1 is realized through the matching of the second rotating shaft 29 and the bearing. The second rotary shaft 29 is spaced further from the a end of the plow frame 2 than the B end of the plow frame 2. A third connecting plate 291 is arranged on the side wall of the second rotating shaft 29, a through hole is arranged on the third connecting plate 291, a threaded hole is arranged on the right side wall of the plow frame 2 corresponding to the through hole, a fourth bolt 292 which can be a polished rod through the middle part passes through the through hole and is in threaded connection with the threaded hole to form a shaft, and the shaft is matched with the third shaft hole 33 on the piston rod 32 to form hinged connection. Two second connecting plates 14 arranged at intervals are arranged at the middle position of the upper part of the suspension bracket 1, a fourth rotating shaft 15 is arranged between the two second connecting plates 14, and the two second connecting plates are matched with a fourth shaft hole 34 on the cylinder body 31 to form hinged connection. Fig. 7 is a mechanism sketch of the plough frame 2 driven by the hydraulic cylinder 3 to rotate. The rotating block 25 can be provided with a fifth rotating shaft 255, the plow frame 2 is provided with a fifth shaft hole 256, and the rotating block 25 is matched with a bearing arranged in the fifth shaft hole 256 through the fifth rotating shaft 255 to form rotatable connection. When the rotary plow is used, when the dragging equipment drags the rotary plow to plough from one end of the field to the other end, the rotary plow is overturned for 180 degrees, and the ploughshare 22 at the other side is used for ploughing. Thus, during forward farming, the direction of turning the soil is the left side of the advancing direction, and during reverse farming, the direction of turning the soil is the right side of the advancing direction. In the specific overturning process, when the piston rod 32 is contracted to the shortest position, the plough frame 2 rotates to the vertical position, the piston rod 32 extends outwards at the moment, the plough frame 2 continues to rotate under the inertia effect until the end A of the plough frame 2 is abutted against the supporting plate 11, the piston rod 32 stops extending, and the overturning action is completed. The land wheel 27 can support the plow frame 2 to make the turnover plow walk more stably during plowing, and can adjust the plowing depth of the plowshare 22. The depth adjustment is specifically performed by unlocking the locking device on the rotary block 25, sliding the slide bar 26 along the slide 251, moving the ground wheel 27 to a position away from or close to the axis of rotation of the rotary block 25, and locking it. During tillage, the land wheel 27 is subjected to resistance action, and drives the rotating block 25 to rotate towards the direction close to the positioning block 28 until the positioning rod 252 on the rotating block 25 is abutted against the positioning plate 281 of the positioning block 28, which is positioned at the lower part. By adjusting the extension length of the slide bar 26, the vertical distance between the land wheel 27 and the plough frame 2 (namely the distance between the plough frame 2 and the ground) is adjusted, the distance between the plough share 22 and the plough frame 2 is constant, and the depth of the plough share 22 entering the field is adjusted. When the reversible plow is reversed, the rotary block 25, together with the slide bar 26 and the land wheel 27, is also reversed, and is now positioned by another positioning plate 281 of the positioning block 28.
In some embodiments, the upper side and the lower side of the plow frame 2 are symmetrically provided with fixing rods 23 corresponding to the plow standard 21 one by one, and one end of each fixing rod 23 far away from the plow frame 2 is rotatably provided with a mowing disc 24. The provision of the mowing disc 24 enables cutting of the roots and stems of weeds or crops in the field, and prevents the roots and stems of weeds or crops from causing resistance to the travel of the reversible plow. Preferably, the ploughshares 22 and the mowing disc 24 are each provided in three pairs (6).
The locking mechanism includes a second threaded hole 253 formed in a side wall of the through slide 251, and a second bolt 254 is threaded in the second threaded hole 253. The slide bar 26 is locked in a certain position by friction force by locking the second bolt 254 so that the end of the second bolt 254 presses the slide bar 26 inwards to press the slide bar 26 against the inner wall of the slide way 251, and the slide bar 26 can slide along the slide way 251 by loosening the second bolt 254.
The support plate 11 is provided with a first threaded hole 111, and a first bolt 112 is screwed in the first threaded hole 111. Therefore, when the plow frame 2 is turned over, the end A of the plow frame 2 will abut against the first bolt 112, and the plow frame 2 can be stopped at a certain angle position with the horizontal plane by adjusting the height of the first bolt 112, so as to finely adjust the plowing angle of the plow share 22.
A third threaded hole 282 is formed in the positioning plate 281, and a third bolt 283 is screwed in the third threaded hole 282. At this time, the positioning rod 252 on the turning block 25 abuts against the third bolt 283, and the angle between the turning block 25 and the horizontal plane when the turning block stops turning can be changed by adjusting the screwing-out length of the third bolt 283, so that the vertical distance between the land wheel 27 and the plow frame 2 can be finely adjusted.
The plow frame 2 can be formed by welding steel pipes, and the weight of the plow frame 2 can be reduced while the use rigidity and the use strength are ensured by adopting the steel pipes.
Wherein, the fixed rod 23 is detachably arranged on the plow frame 2. Specifically, two fixing rods 23 which are symmetrical up and down are welded into an integral structure through a fixing plate 231, as shown in fig. 8, through holes 232 are formed in four corners of the fixing plate 231, the plow frame 2 is sleeved on the U-shaped connecting member 233, external threads are formed at two ends of the U-shaped connecting member 233, and nuts are screwed on two ends of the U-shaped connecting member 233 through the through holes 232, so that the fixing rods 23 are fixed on the plow frame 2. So set up, conveniently adjust the position of dead lever 23, make it set up in the position of being convenient for cut weeds or crops stem root.
The cross-section of the slide 251 is rectangular. The rectangular cross-section prevents slide bar 26 from rotating within slide 251, and second slide 251 may be fabricated from a steel tube having a rectangular cross-section.
The land wheel 27 may be provided as a rubber wheel. When the rubber wheels are adopted to cultivate on soft sand, the rubber wheels can be prevented from falling into the sand.
It is understood that the same or similar parts in the above embodiments may be mutually referred to, and the same or similar parts in other embodiments may be referred to for the content which is not described in detail in some embodiments.
Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the scope of the present invention.
