[0001] The utility model relates to the technical field of rotary tillers, and more specifically to a bulldozer mechanism of a rotary tiller. Background Art

[0002] Crawler-type rotary tillers are widely used as agricultural tillage machines. Uneven soil can affect subsequent planting and irrigation, ultimately impacting crop yields. Adding a bulldozer to a crawler-type rotary tiller can effectively improve field flatness. However, the existing bulldozer mechanism, with its support rods installed at the bottom of the lower frame, lacks sufficient lift height, impacting its maneuverability. Furthermore, the overall structural stability needs to be improved. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] refer to Figure 1-2 The bulldozer mechanism of the rotary tiller includes a rotary tiller body, on which an upper frame 1 spaced from the ground is provided, and further includes: a main beam 2 mounted on the upper frame 1; two mounting brackets 3, which are provided and mounted on the main beam 2 at intervals; two upper support rods 4 and two lower support rods 5, each of which has two, one end of the two upper support rods 4 and the two lower support rods 5 being movably connected to the top end and the bottom end of the two mounting brackets 3 respectively, and the other end being movably connected to the bulldozer bucket 6, thereby making the upper support rod 4 and the lower support parallel; a telescopic drive 7, one end of the telescopic drive 7 being movably connected to the main beam 2 between the two mounting brackets 3, and the other end being movably connected to the lower support rod 5.

[0021] It can be understood that the rotary tiller body is a machine that can perform rotary tillage work in the field. The upper frame 1 is located above the lower frame and has a certain height on the rotary tiller body. Since they are all existing technologies, they are not marked in the accompanying drawings. The main beam 2 is a mounting component for the entire bulldozer mechanism. For example, it can be a crossbeam structure or a body structure, etc., but not limited to this. The mounting bracket 3 is a component used to connect the upper support rod 4 and the lower support rod 5. For example, it can be a rod-shaped structure or a sheet-shaped structure, etc., but not limited to this. The upper support rod 4 and the lower support rod 5 are components that flexibly connect the bulldozer bucket 6. For example, they can be square rods or round rods, etc., but not limited to this. The telescopic drive 7 is a component that telescopically drives the upper support rod 4 and the lower support rod 5 to swing up and down to lift the bulldozer bucket 6. For example, it can be a hydraulic cylinder, an air cylinder, an electric cylinder, etc., but not limited to this. In the above, each movable connection can be connected by a hinge or a pin shaft and a pin hole, etc., but not limited to this.

[0022] With this arrangement, the bulldozer structure is mounted on the main beam 2 of the rotary tiller's upper frame 1, raising the bulldozer mechanism as a whole, ensuring the tiller's ability to pass through. The bulldozer mechanism also significantly improves the flatness of the field through leveling. The parallelogram structure formed by the mounting bracket 3, upper support rod 4, lower support rod 5, and bulldozer bucket 6 ensures that the angle of the bulldozer bucket 6 remains unchanged during its ascent and descent, maintaining structural stability and facilitating the operation of the bulldozer bucket 6 at various heights. During operation, the output end of the telescopic actuator 7 extends, causing the upper and lower support rods 4 and 5 to swing downward, lowering the bulldozer bucket 6. When the output end of the telescopic actuator 7 retracts, the upper and lower support rods 4 and 5 to swing upward, raising the bulldozer bucket 6.

[0023] In some embodiments, the top and bottom ends of the mounting bracket 3 each define a slot 31 for engaging with the upper support rod 4 and the lower support rod 5. Pin holes are defined on either side of the slot 31. Pin holes are also defined on the upper and lower support rods 4, 5. After the upper and lower support rods 4, 5 are inserted into the slots 31, respectively, a pin is inserted into the slot holes to lock the upper and lower support rods 4, 5. The provision of the slot 31 enhances the stability of the connection with the upper and lower support rods 4, 5.

[0024] In some embodiments, at least one reinforcement rod 9 is installed between each of the two upper support rods 4 and the two lower support rods 5. The output end of the telescopic actuator 7 is movably connected to the reinforcement rod 9 on the lower support rod 5. Here, the reinforcement rod 9 connects the two upper support rods 4 and the two lower support rods 5 together, thereby enhancing structural strength. It also facilitates the central connection of the telescopic actuator 7.

[0025] For example, the telescopic actuator 7 is a hydraulic cylinder connected to a solenoid valve 8 that controls the cylinder's extension and retraction. The solenoid valve 8 is connected to a hydraulic system. The solenoid valve 8 can be removably mounted using bolts or clamping fixtures. Thus, the hydraulic cylinder's extension and retraction, and thus the raising and lowering of the bulldozer bucket 6, are controlled by controlling the flow of oil into and out of the solenoid valve 8.

[0026] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
