Technical Field

[0001] This utility model relates to the technical field of lawn mowers and flatteners, specifically a tractor-mounted lawn mower and flattener. Background Technology

[0002] A hay cutter and flattener is a type of machinery specifically designed for harvesting forage, primarily used in crop farming and animal husbandry. It is a forage harvesting machine that completes the cutting, flattening, and stripping operations in one operation. Also known as a hay cutter and flattener, it flattens and cracks the cut fresh forage stalks, accelerating the evaporation of internal moisture, shortening drying time, and ensuring uniform drying of stalks, leaves, and flowers, thereby reducing nutrient loss and improving hay quality. It is often used in humid, high-yield pastures for harvesting leguminous forage.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3A towable lawn mower and flattener includes a support frame 1. A hydraulic cylinder 6 is installed inside the support frame 1. A connecting plate 5 is installed at the output end of the hydraulic cylinder 6. A spring 17 is installed below the connecting plate 5. A limit cylinder 18 is installed inside the spring 17. A limit rod 20 is movably installed inside the limit cylinder 18. A weeding box 2 is installed below the limit rod 20. The connecting plate 5 is fixedly connected to the limit cylinder 18, and the connecting plate 5 is movably connected to the weeding box 2 through the limit cylinder 18 and the limit rod 20. Furthermore, the connecting plate 5 is elastically connected to the weeding box 2 through the spring 17. Next, a distance-limiting wheel 19 is installed below the weeding box 2; the distance-limiting wheel 19 is evenly distributed along the lower surface of the weeding box 2. A connecting rod 8 is installed on the right side of the support frame 1, and a connecting block 7 is fixedly installed on the right side of the connecting rod 8. A movable groove 11 is opened inside the connecting block 7, and a movable block 9 is movably installed inside the movable groove 11. Limiting sliding grooves 16 are opened on both sides of the inner wall of the movable groove 11, and limiting sliders 15 are movably installed inside the limiting sliding grooves 16; the movable block 9 is fixedly connected to the limiting slider 15, and the movable block 9 is connected to the limiting slider 15 by the limiting slider 15. The slot 16 moves within the movable slot 11. An extension frame 3 is fixedly installed on the left side of the support frame 1, and a traveling wheel 4 is installed below the extension frame 3. The extension frame 3 and the traveling wheel 4 cooperate with the support frame 1 to form a self-sufficient structure, eliminating the need for a tractor to provide support. This allows the mowing box 2 to move along the ground, and the movable block 9 moves up and down within the movable slot 11, preventing the tractor from driving the mower and flattener to rotate back and forth. At the same time, the setting of the distance-limiting wheel 19 ensures that the mowing box 2 always maintains a certain distance from the ground. The three work together to prevent the towed mower and flattener from scratching the soil when working in complex terrains such as hilly areas. The squeezing roller 21 is installed inside the mowing box 2, and a cutter 22 is installed at the front end of the squeezing roller 21. The first connecting frame 10 is installed on the right side of the movable block 9. A second connecting shaft 13 is movably installed inside the first connecting frame 10, and a second connecting frame 14 is installed on the right side of the first connecting frame 10. A first connecting shaft 12 is movably installed inside the second connecting frame 14, and the first connecting shaft 12 and the second connecting shaft 13 are fixedly connected.

[0021] Working Principle: When using this towed mower and ballast, the tractor first connects to the towed mower and ballast via the first connecting frame 10 and the second connecting frame 14, and pulls the towed mower and ballast to move. The controller controls the hydraulic cylinder 6 to push the connecting plate 5 downward a certain distance, which in turn drives the weeding box 2 downward a certain distance, so that the limiting wheel 19 contacts the ground. Then, the controller controls the squeezing roller 21 and the cutter 22 to cut and ballast the grass. The squeezing roller 21 and the cutter 22 are existing technologies and will not be described in detail here. Secondly, when traveling on uneven ground, the limiting wheel 19 pushes the weeding box 2 to move up and down through the spring 17, the limiting cylinder 18 and the limiting rod 20, which plays a buffering role and avoids soil digging. Furthermore, when the tractor travels on uneven ground, the tractor moves up and down, driving the movable block 9 to move up and down inside the movable groove 11, which will not affect the walking state of the support frame 1 and the extension frame 3. This is the working principle of the towed mower and ballast.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
