Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a reversible plowshare. Background Technology

[0002] Agricultural production requires tilling the land to transform a compacted soil layer into a loose, fine-textured topsoil layer. This increases soil porosity, facilitating water storage and nutrient dispersal for crops, thus promoting healthy root growth. The agricultural implement used for tilling is typically a plowshare. With the widespread adoption of agricultural mechanization, combined plowshares for large-scale tilling, driven by tractors, have enabled rapid land preparation, further freeing up agricultural labor. However, there is still room for continuous improvement and innovation in combined plowshares.

It often requires a large bending radius to plow the plowed area again. Therefore, the above-mentioned defects require further improvement of the combined plowshare to further reduce the workload of agricultural workers, while also achieving the desired effect after plowing.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings: This embodiment is implemented based on the technical solution of the present invention and provides detailed implementation methods, but the protection scope of the present invention is not limited to the following embodiments.

[0022] Example 1: As Figure 1 As shown, this embodiment relates to a tilting plowshare, including a support 1 rotatably connected to a traction frame 5 via a rotating shaft 7; the support 1 has a plurality of plowshares 3 evenly distributed front and rear, fixedly connected by a connector 34, and a support wheel 2 fixedly connected; the plowshare 3 includes an upper plow blade 31 and a lower plow blade 32 connected by a plow frame 33 and symmetrically arranged; the support wheel 2 includes an upper support wheel 21 and a lower support wheel 22 symmetrically arranged; the traction frame 5 rotates along the rotating shaft 7, the rotating shaft 7 being fixed to the rear end of the support 1; a hydraulic device 4 is fixedly installed on the traction frame 5, and the output end of the hydraulic device 4 is rotatably connected to the rotating shaft 7.

[0023] During the tillage process of the tractor driving the aforementioned reversible plowshare from one end of the field to the other, the lower support wheel 22 provides support to the ground and drives the support 1 to move accordingly. At this time, the lower plowshare 32 is positioned below the lower support wheel 22, effectively tilling the land. After tilling to the other end of the field, the tractor turns around, adjusts and lowers the support height of the lower support wheel 22, and drives the rotating shaft 7 to rotate via the output end of the hydraulic device 4. The support 1 then rotates 180° counterclockwise along the rotating shaft 7. At this time, the upper plowshare 31 is positioned below and inserted into the soil, and the support wheel 21 provides support to the ground. The tractor then drives the aforementioned reversible plowshare in the opposite direction to till the land. Using this reversible plowshare avoids the need for the tractor to make a large-radius bend to turn back during tillage. Only a simple reversing operation of the reversible plowshare is required before the return trip, which reduces the workload of agricultural workers to a certain extent, saves time, and achieves good tillage results.

[0024] Optionally, in order to further enhance the stability of the support 1, the aforementioned reversible plowshare also includes a limiting block 6 fixed on the traction frame 5. When the reversible plowshare is in the tillage operation state, the limiting block 6 is used to restrict the rotation of the support 1 in order to maintain the stability of the plowshare 3.

[0025] Example 2, as Figure 2 As shown, the specific structure of the above-mentioned tilting plowshare is as follows:

[0026] Support 1 includes a triangular composite beam composed of an inclined beam 11, a straight beam 12, and a crossbeam 13, with the front end of the inclined beam 11 being a long extension and the rear end of the straight beam 12 being a short extension. A reinforcing beam 14 is provided in the middle of the triangular composite beam to connect the inclined beam 11 and the straight beam 12. Square grooves are evenly distributed on the inclined beam 11 for installing plowshares 3. Mounting holes for fixing the rotating shaft 7 are provided on the crossbeam 13 and the reinforcing beam 14 for fixing and connecting the rotating shaft 7. A support wheel 2 is installed on the straight beam 12.

[0027] The upper support wheel 21 includes an upper roller 211, which is rotatably connected to one end of the inner support 212 of the upper roller. The inner support 212 of the upper roller has multiple evenly distributed pin holes, which are fitted into the outer support 213 of the upper roller and can move up and down to adjust the fitting depth. A pin hole is provided at the end where the inner support 212 of the upper roller fits into the outer support 213 of the upper roller, and the relative positions of the inner support 212 of the upper roller and the outer support 213 of the upper roller are fixed by the upper roller pin 214.

[0028] The lower support wheel 22 includes a lower roller 221, an inner support 222, an outer support 223, and a pin 224, and its connection structure is the same as that of the upper support wheel 21.

[0029] The above structure, on the one hand, ensures the reliability of support 1 and achieves better support effect; on the other hand, it enables height adjustment of the upper support wheel 21 and the lower support wheel 22, thereby meeting the different depth requirements when the plowshare 3 tills the land. When the upper plowshare 31 is flipped to the ground, the inner support 222 of the lower roller is retracted into the outer support 223 of the lower roller, reducing the height of the lower support wheel 22. The inner support 222 and the outer support 223 of the lower roller are then fixed with the lower roller pin 224.

[0030] like Figure 3 As shown, the towing frame 5 includes a crossbeam 51, and a trapezoidal column 52 is fixedly connected to the middle of the crossbeam 51. The middle of the crossbeam 51 has bearing holes for fixing the outer ring of the bearing 55 in the front and rear direction. The two ends of the rear of the crossbeam 51 are symmetrically provided with connectors (not shown in the figure) that are connected to and adapted to the tractor. A groove-shaped fixing head 53 is fixedly connected to the upper part of the column 52. The fixing head 53 has process holes at the upper and lower rear of the rear part. Pins are installed in the process holes to be movably connected to the tractor. A first connecting lug 54 is provided at the upper front part of the fixing head 53.

[0031] The hydraulic device 4 includes a cylinder body 41, with a shaft hole on the first connecting lug 54, which is connected to the annular hole at the top of the cylinder body 41 via a rotating shaft; a telescopic hydraulic shaft 42 is installed inside the cylinder body 41; threaded holes for connecting oil pipes 44 are provided at the upper and lower parts of the cylinder body 41; there is a pair of oil pipes 44, which are connected to hydraulic valves 43 respectively. When the hydraulic valves 43 are opened and closed, hydraulic oil flows in the oil pipes 44; when hydraulic oil is pressed into the upper oil pipe 44, hydraulic oil is discharged from the lower oil pipe 44, and the hydraulic shaft 42 moves downward, and vice versa.

[0032] The rotating shaft 7 includes a round shaft 71, the rear end of which is fixedly installed at the inner ring of the bearing 55, and a second connecting lug 72 is fixedly connected to the near end of the bearing 55; the second connecting lug 72 has a shaft hole, which is connected to the annular hole at the bottom of the hydraulic shaft 42 through another rotating shaft.

[0033] The limiting block 6 includes a left limiting block 61 and a right limiting block 62; the left limiting block 61 includes a left strip block 611 fixed to the upper left end of the crossbeam 51, and the front of the left strip block 611 has a screw hole for installing the left bolt 612; the right limiting block 62 includes a right strip block 621 and a right bolt 622, and its connection structure is the same as that of the left limiting block 61; the left bolt 612 or the right bolt 622 is used to limit the rotation of the short extension end where the straight beam 12 is located.

[0034] Reference Figure 1As shown, when the straight beam 12 is on the left, the hydraulic shaft 42 presses against the second connecting lug 72 on the right side of the rotating shaft 7. At this time, the left bolt 612 limits the short extension end where the straight beam 12 is located, so the support 1 is reliably fixed and will not rotate. If the support 1 is rotated, after the hydraulic device 4 is started, the hydraulic shaft 42 retracts, and at the same time the cylinder 41 swings clockwise along the first connecting lug 54 to drive the rotating shaft 7 to rotate. After passing the rotation dead point by inertia, the hydraulic shaft 42 extends, thereby driving the support 1 to rotate 180°. When the straight beam 12 is on the right, the hydraulic shaft 42 presses against the second connecting lug 72 on the left side of the rotating shaft 7. At this time, the right bolt 622 limits the short extension end where the straight beam 12 is located, so the support 1 is reliably fixed and will not rotate.

[0035] like Figure 4 As shown, the upper moldboard blade 31 is mounted on the upper part of the moldboard frame 33 via the fixing plate 36, and the lower moldboard blade 32 is mounted on the lower part of the moldboard frame 33 via the fixing plate 36; the moldboard frame 33 has a mounting hole for mounting the connecting piece 34 in the middle; the connecting piece 34 is a U-shaped retaining ring with threads at both ends, which, together with the nut 35, is used to install the moldboard frame 33 into the square groove where the inclined beam 11 is located.

[0036] The U-shaped retaining ring serves as a connecting component, protecting the upper moldboard 31 or lower moldboard 32 from breakage due to overload, while also providing replaceability.
