[0017] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0018] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.
[0019] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a ridge loosening and weeding spike rake, comprising a rake head, a grip rod 3 and a fixed head 4, the rake head comprising a rake frame 1, an arc-shaped rod 7, a plurality of rake teeth 2 and a plurality of connecting rods, the connecting rods are respectively mounted on both ends of the rake frame 1, both ends of the arc-shaped rod 7 are mounted on the connecting rods through hinges, a plurality of rake teeth 2 are mounted on the rake frame 1, the fixed head 4 is mounted on one end of the grip rod 3, the middle of the arc-shaped rod 7 is mounted above the fixed head 4, a positioning port is provided on the fixed head 4, a support positioning column 5 is provided in the positioning port, one end of the support positioning column 5 is mounted on the rake frame 1, and an adjustment component for changing the shape of the rake frame 1 is installed on the fixed head 4.
[0021] In this embodiment, the adjustment assembly includes a sealed bearing, a screw 11, a lever 10 and a fixing frame 8. The fixing frame 8 is mounted on the fixed head 4. One end of the fixing frame 8 extends to the outside of the support positioning column 5. A screw hole 12 is axially provided at the center of the support positioning column 5. The fixing frame 8 is provided with a mounting hole directly opposite the screw hole 12. The sealed bearing is mounted in the mounting hole. The screw 11 is mounted in the inner ring of the sealed bearing. One end of the screw 11 is threadedly connected to the screw hole, and the other end is expanded outward to form an operating portion 9. The operating portion 9 is provided with a socket, and one end of the lever 10 is inserted into the socket;
[0022] Among them, the lever is plug-in set, so when the lever is loosening the soil and weeding, the lever can be pulled out from the socket to avoid affecting the operation.
[0023] In this embodiment, the rake frame 1 is made of spring steel, and the cross-section of the rake frame 1 is a flat structure. The rake frame 1 is in a bent state due to the support positioning column 5 moving downward or upward. The flat structure of the rake frame can rebound and bend better, and the spring steel itself has a large strength and can perform soil loosening operations. The spring steel can be bent, and as long as the degree of bending does not exceed its own rebound limit, it can return to its original position later.
[0024] In this embodiment, the arc rods 7 are all made of steel material, which increases the firmness and can better support the rebound from the rake frame.
[0025] In this embodiment, a rubber sleeve is installed at the end of the handle 3 away from the fixed head 4. The rubber sleeve increases the friction when holding the handle, which can better perform loosening and weeding operations.
[0026] In this embodiment, a space is formed between the support and positioning column 5 and the fixing frame 8 for the support and positioning column 5 to rise, thereby increasing an arc-shaped adjustment distance.
[0027] When loosening the soil and weeding the curved ridge surface, a lever can be prepared, one end of the lever can be inserted into the socket, and the operating part and the screw rod can be rotated with ease through the lever principle, and the rotation of the screw rod drives the support positioning column to move the support positioning column downward or upward along the positioning port. Since the two ends of the rake frame are pulled by the curved rod, when the support positioning column descends, the rake frame can be pressed into a "︶"-shaped structure, and conversely, when the support positioning column rises, the rake frame can be pressed into a "︵"-shaped structure, and the curvature of the rake frame can be changed by the distance the support positioning column descends or rises, so as to adapt to ridge surfaces of different curvatures, thereby increasing adaptability;
[0028] When loosening and weeding flat soil, the screw rod can be rotated through the lever to move the supporting positioning column to the middle. At this time, the downward pressure and upward pulling force on the harrow frame are lost, and the harrow frame rebounds through its own elastic energy, making the harrow frame in a horizontal state to adapt to the flat soil.
[0029] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
