Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, and in particular to a threaded connecting strip for an agricultural rake. Background Technology

[0002] In traditional agricultural operations, the agricultural harrow is a core tool for turning over soil, breaking up soil, weeding, and raking grass. Its structural design and ease of use directly affect operational efficiency and maintenance costs.

[0003] Referring to existing patent publication number CN211457889U, an agricultural harrow for tilling includes a harrow handle and a harrow head. The harrow head includes a crossbeam and harrow teeth connected to the lower part of the crossbeam. The harrow handle is connected to the upper part of the crossbeam. It also includes a horizontal tube and a limiting member connected to the lower part of the crossbeam. The horizontal tube is suspended below the crossbeam by a flexible connector, and the connection end of the flexible connector to the crossbeam is located between the harrow teeth and the limiting member. This utility model's agricultural harrow is simple and labor-saving, particularly suitable for tilling and loosening soil in farmland. Its simple structure and ease of use can reduce the labor intensity of rural residents left behind.

[0004] However, in traditional agricultural harrows, components such as harrow blades and harrow teeth are usually fixed directly to the harrow frame by welding or bolts. The harrow teeth are prone to wear or breakage due to long-term friction with soil and stones, requiring the entire harrow body to be replaced or disassembled with professional tools, resulting in long maintenance cycles and high costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a threaded connecting strip for agricultural rakes. This invention utilizes a threaded connection between the rake teeth and the rake head, allowing for individual replacement of damaged rake teeth during use. This avoids the need for scrapping or maintaining the entire rake, reducing losses and facilitating tooth replacement. Furthermore, a positioning component between the rake teeth and the mounting part improves installation accuracy, reduces misalignment, enhances overall rigidity, and improves performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A threaded connecting strip for an agricultural rake includes:

[0008] Main body, rake body main frame;

[0009] The connecting handle is fixedly welded to the surface of the main body;

[0010] The mounting part is integrally disposed at the lower part of the main body;

[0011] A connecting hole is formed inside the mounting part, and a rake tooth is threaded into the connecting hole;

[0012] A positioning component is constructed between the rake teeth and the mounting part, and a limiting component is connected to the surface of the mounting part.

[0013] The present invention is further configured such that the positioning component includes: a positioning post and a positioning hole;

[0014] The positioning post is constructed inside the mounting section, and the positioning hole is opened inside the rake teeth.

[0015] The present invention is further configured such that the limiting component includes: an elastic element and a limiting element;

[0016] The limiting member is connected to the surface of the mounting part by an elastic member, and the limiting member extends into the mounting part.

[0017] The present invention is further configured such that the surface of the rake teeth is provided with a limiting hole corresponding to the limiting member.

[0018] The present invention is further configured such that one end of the limiting member that extends into the mounting portion has a first inclined surface.

[0019] The present invention is further configured such that the upper part of the rake teeth has rounded chamfers.

[0020] The present invention is further configured such that the main body is made of high-strength metal material and the surface is coated with an anti-rust layer.

[0021] The present invention is further configured such that the positioning post and the positioning hole are correspondingly arranged.

[0022] The beneficial effects of this utility model are as follows: By constructing a thread at the connection between the rake teeth and the rake head, the rake teeth can be replaced individually if they are damaged during use, avoiding the need to scrap or maintain the entire rake, reducing losses, and making the replacement of the rake teeth more convenient. The positioning component constructed between the rake teeth and the mounting part can improve the installation accuracy, reduce offset, and improve the overall rigidity, thereby improving the performance.

[0023] This agricultural rake features a threaded connecting strip. By incorporating threads and a positioning component, the rake teeth and rake head are connected in a detachable threaded manner. This allows for individual replacement of damaged rake teeth during use, avoiding the need to scrap or maintain the entire rake, thus reducing losses. The replacement of rake teeth is also more convenient. The positioning component between the rake teeth and the mounting part improves installation accuracy, reduces misalignment, and enhances overall rigidity, thereby improving performance.

[0024] This agricultural rake with a threaded connecting strip has a limiting component. To prevent the rake teeth from loosening during use after being connected by the thread, when the rake teeth are connected, as they align with the mounting part, the rake teeth push the limiting component outward and stretch the elastic component. After the rake teeth are aligned with the mounting part, the limiting hole on the surface of the rake teeth aligns with the limiting component. At this point, the limiting component can be inserted into the limiting hole under the action of the elastic component, thereby further fixing the rake teeth, reducing loosening, and improving connection strength.

[0031] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0032] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0033] In the description of this patent, it should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0034] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0035] Reference Figures 1 to 5 A type of agricultural rake with a threaded connecting strip includes: a main body 1, a rake body main frame; a connecting handle 2, which is fixedly welded to the surface of the main body 1 and welded to the top of the main body 1, adapted to hand-held or power-driven traction equipment for easy connection and traction; a mounting part 3, which is integrally set in the lower part of the main body 1; a connecting hole 7, which is opened inside the mounting part 3, and a rake tooth 4 is connected to the connecting hole 7 by a thread 6. The mounting part 3 is integrally cast with the main body 1, and has a connecting hole 7 with an internal thread 6 inside. The top of the rake tooth 4 is provided with an external thread interface, which can be quickly locked by rotation. The rake tooth 4 can be replaced individually, avoiding the need to scrap or maintain the entire rake, thus reducing losses. A positioning component is constructed between the rake tooth 4 and the mounting part 3 to improve the installation accuracy of the rake tooth 4 and reduce offset. A limiting component is connected to the surface of the mounting part 3, which can be used to further improve the connection strength of the rake tooth 4 and reduce loosening and falling off.

[0036] Specifically, refer to Figures 2 to 4 The positioning components include: a positioning post 5 and a positioning hole 8; the positioning post 5 is constructed inside the mounting part 3, and the positioning hole 8 is opened inside the rake tooth 4. Furthermore, the positioning post 5 and the positioning hole 8 are correspondingly set. Through this design, the positioning hole 8 of the rake tooth 4 is aligned with the positioning post 5 of the mounting part 3 to achieve preliminary mechanical positioning. Under the guidance of the positioning post 5, the threaded interface of the rake tooth 4 is precisely aligned with the thread 6 of the connecting hole 7 to complete the tightening operation, which is convenient for operation.

[0037] Specifically, refer to Figures 3 to 5The limiting components include: an elastic member 11 and a limiting member 10; the limiting member 10 is connected to the surface of the mounting part 3 through the elastic member 11, and the limiting member 10 extends into the mounting part 3. Furthermore, the surface of the rake tooth 4 is provided with a limiting hole 9 corresponding to the limiting member 10. With this design, when connecting the rake tooth 4 to the mounting part 3, the operator can first pull the limiting member 10 outward. At this time, the limiting member 10 can stretch the elastic member 11 and disengage from the connecting hole 7. Then, as the rake tooth 4 is threadedly connected to the mounting part 3, the limiting hole 9 on the surface of the rake tooth 4 can correspond to the limiting member 10. At this time, the limiting member 10 can be inserted into the limiting hole 9 under the action of the elastic member 11, thereby further fixing the rake tooth 4, reducing loosening, and improving the connection strength.

[0038] Furthermore, the end of the limiting member 10 that extends into the mounting portion 3 is constructed with a first inclined surface.

[0039] The upper part of the rake tooth 4 has a rounded chamfer. This design allows the rounded chamfer at the top of the rake tooth 4 to push the limiting member 10 with the first inclined surface to move horizontally when the rake tooth 4 is connected. The two work together to make the movement smoother, thereby opening the limiting member 10 and reducing the need for personnel to operate the limiting member 10.

[0040] Furthermore, the main body 1 is made of high-strength metal and coated with an anti-rust layer. Through this design, the high-strength metal can withstand the impact and fatigue load during operation, avoiding deformation or breakage and improving the performance of the rake.

[0041] Working principle: When using this utility model, the rake teeth 4 and the rake head are first detachably connected by threads 6. This allows the rake teeth 4 to be replaced individually if damaged during use, avoiding the need to scrap or maintain the entire rake, reducing losses, and making replacement of the rake teeth 4 more convenient. The positioning component between the rake teeth 4 and the mounting part 3 improves installation accuracy, reduces offset, and increases overall rigidity, thus improving performance. To prevent the rake teeth 4 from loosening during use after being connected by threads, when connecting the rake teeth 4, as the rake teeth 4 align with the mounting part 3, the rake teeth 4 pushes the limiting member 10 outward and stretches the elastic member 11. After the rake teeth 4 and the mounting part 3 are aligned, the limiting hole 9 on the surface of the rake teeth 4 corresponds to the limiting member 10. At this time, the limiting member 10 can be inserted into the limiting hole 9 under the action of the elastic member 11, thereby further fixing the rake teeth 4, reducing loosening, and improving connection strength.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
