Description

Technical Field

[0001] This utility model relates to a single-legged rake, and more specifically, to a two-winged single-legged rake. Background Technology

[0002] With the increasing mechanization of agricultural operations, large machinery is increasingly used for tilling, planting, irrigation, and harvesting of crops. This machinery not only improves agricultural efficiency but also saves manpower and resources. The disc harrow, as one of the agricultural machines used for tilling and soil pulverization, can both till and pulverize the soil under the drive of a tractor, and is widely used in deep loosening and reclamation operations. To ensure operational efficiency, existing disc harrows typically have a large working width, often exceeding 5 meters. While this wider width results in higher efficiency, it also limits its use, as it cannot be driven on roads and must be transported by other vehicles.

[0003] Meanwhile, for existing disc harrows, the disc plow is fixed to the support by square tube-shaped plow legs. Although the square tube-shaped plow legs can provide a firm support for the disc plow, the high strength of the square tube-shaped plow legs prevents them from undergoing large deformations. When the lower end of the disc plow encounters hard obstacles such as stones, it is easy to damage the disc plow and reduce the service life of the disc harrow. Summary of the Invention

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 7As shown, the front view, rear view, left view, right view, top view, bottom view and perspective view of the two-wing single-leg harrow of this utility model are given respectively. The two-wing single-leg harrow shown is composed of a traction frame 1, a main horizontal frame 2, a left folding frame 3, a right folding frame 4, a main lifting cylinder 7 and a harrow disc mechanism. The traction frame 1 and the main horizontal frame 2 are both rectangular frames in shape. The traction frame 1 and the main horizontal frame 2 are both horizontally set. The traction frame 1 is used to connect with the traction machinery so that the traction machinery can drag the entire single-leg harrow for tillage operation. The rear end of the traction frame 1 is hinged to the front end of the main horizontal frame 2. The front vertical frame 5 and the rear vertical frame 6 are fixed on the traction frame 1 and the main horizontal frame 2 respectively. The rear end of the front vertical frame 5 and the front end of the rear vertical frame 6 are hinged to the two ends of the main lifting cylinder 7 respectively. In this way, when tillage is required, the main lifting cylinder 7 extends and lowers the main horizontal frame 2 to facilitate tillage. When passing through the field, the main lifting cylinder 7 retracts and lifts the main horizontal frame 2 to complete the turning and turning.

[0018] The left-folding display frame 3 and the right-folding display frame 4 are hinged to the left and right sides of the main horizontal frame 2, respectively. The main horizontal frame 2 is equipped with a left hydraulic cylinder 8 and a right hydraulic cylinder 9. The two ends of the left hydraulic cylinder 8 are hinged to the left-folding display frame 3 and the main horizontal frame 2, respectively, and the two ends of the right hydraulic cylinder 9 are hinged to the right-folding display frame 4 and the main horizontal frame 2, respectively. Thus, by extending and retracting the left hydraulic cylinder 8 and the right hydraulic cylinder 9, the left-folding display frame 3 and the right-folding display frame 4 can be driven to fold and unfold. When the left-folding display frame 3 and the right-folding display frame 4 are unfolded, farmland plowing operations can be carried out. When the left-folding display frame 3 and the right-folding display frame 4 are folded up, their width decreases, allowing for transportation on roads.

[0019] Both the left-folding display frame 3 and the right-folding display frame 4 are equipped with a harrowing disc mechanism. The harrowing disc mechanism consists of a front harrowing disc shaft 11, a rear harrowing disc shaft 12, an auger 19, harrowing disc legs 13, and a circular harrowing disc 14. The front harrowing disc shaft 11 and the rear harrowing disc shaft 12 are respectively located on the lower front and rear sides of the left-folding display frame 3 or the right-folding display frame 4. Both the front harrowing disc shaft 11 and the rear harrowing disc shaft 12 are fixed to the left-folding display frame 3 or the right-folding display frame 4 by wing plates 10. The front harrowing disc shaft 11 and the rear harrowing disc shaft 12 are fixed with downward-facing harrowing disc legs 13 at intervals along their length. The lower end of the harrowing disc legs 13 is equipped with a circular harrowing disc 14, which is connected to the harrowing disc legs 13 via bearings. In this way, when the farmland is tilled, the circular harrowing disc 14 cuts into the soil to achieve soil pulverization and tillage.

[0020] The auger 19 is located behind the rear harrow disc shaft 12. Both ends of the auger 19 are rotatably mounted on the ends of the auger support shaft 20, which is hinged to the rear harrow disc shaft 12 via the auger connecting rod 21. An auger cylinder 22 is installed between the rear harrow disc shaft 12 and the auger support shaft 20. Both ends of the auger cylinder 22 are hinged to the rear harrow disc shaft 12 and the auger support shaft 20, respectively. Thus, the extension of the auger cylinder 22 controls the sinking of the auger 19, thereby achieving the crushing and leveling of the tilled soil.

[0021] After the left-folding display stand 3 and the right-folding display stand 4 are folded up, to ensure they remain in the folded state, a left locking rod 17 and a right locking rod 15 are respectively installed on the left-folding display stand 3 and the right-folding display stand 4. The lower end of the left locking rod 17 is fixed to the left-folding display stand 3, and the upper end of the left locking rod 17 is provided with a locking port 18. The lower end of the right locking rod 15 is hinged to the right-folding display stand 4, and the middle part of the right locking rod 15 is hinged to the right-folding display stand 4 via a locking cylinder 16. The upper end of the right locking rod 15 is provided with a hook that cooperates with the locking port 18. When the left-folding display stand 3 and the right-folding display stand 4 are folded up, the hook at the front end of the right locking rod 15 engages with the locking port 18 to keep the left-folding display stand 3 and the right-folding display stand 4 in the upward folded state, ensuring their safety during road travel. Figure 9 The diagram shows the two-winged single-legged rake of this utility model in its folded state.

[0022] When the two-bladed single-leg harrow is transported on the road, the traveling wheels 26 provide support. The traveling wheels 26 are rotatably mounted at the end of the rear axle 18, which is hinged to the rear end of the main horizontal frame 2 via a rear wheel connecting rod 29. The rear axle 18 and the main horizontal frame 2 are connected via a rear wheel cylinder 30, with both ends of the rear wheel cylinder 30 hinged to the rear axle 28 and the main horizontal frame 2, respectively. Thus, when the single-leg harrow tills the farmland, the rear wheel cylinder 30 drives the traveling wheels 26 to lift; when the single-leg harrow travels on the road, the rear wheel cylinder 30 drives the traveling wheels 26 to lower, thus providing support for the entire single-leg harrow.

[0023] The depth limiting wheel 25 is rotatably mounted on the front wheel support leg 31. The front wheel support leg 31 is hinged to the ear plate 34 via the front wheel axle. The ear plate 34 is fixed to the wing plate 10. A drive rod 32 is fixed on the front wheel axle. The end of the drive rod 32 is hinged to the ear plate 34 via a manual telescopic rod 33. The manual telescopic rod 33 consists of an outer sleeve and two screws located in the outer sleeve. The two screws are threaded to the outer sleeve. The outer ends of the two screws are respectively hinged to the drive rod 32 and the ear plate 34. In this way, by rotating the outer sleeve, the manual telescopic rod 33 can be driven to extend and retract, thereby controlling the rotation of the depth limiting wheel 25 and realizing the adjustment of the tillage depth.

[0024] The traction frame 1 shown is equipped with a support leg 23, the upper end of which is hinged to the traction frame 1. The traction frame 1 is equipped with a support leg cylinder 24, the two ends of which are respectively hinged to the traction frame 1 and the middle of the support leg 23. After the support leg cylinder 24 drives the support leg 23 downwards, the lower end of the support leg 23 and the two wheels 26 contact the ground, thus achieving stable three-point support for the entire single-leg rake.
