Description

Technical Field

[0001] This utility model relates to the field of cutting platform technology, specifically to a quick-disassembly connection structure for a cutting platform intermediate cover. Background Technology

[0002] The header is the core operating component of agricultural harvesting machinery, integrating key mechanisms such as cutting and conveying. The intermediate cover, as an important part of the header, primarily protects the internal transmission structure, guides material transport, and prevents impurities from entering, playing a crucial role in the stable operation of the header. With the popularization of agricultural mechanization, detachable structures are increasingly used in header design to improve the ease of maintenance and flexibility of field relocation.

[0003] For example, the national authorized patent announcement number CN201911041U discloses a harvester with a detachable header, including a harvester working part and a frame. The harvester working part is movably connected to the frame and is detachable. The harvester working part includes a header and a threshing chamber, with the header movably connected to the threshing chamber and also detachable. This utility model solves the problem of the harvester working part being too large and heavy to move in the field by setting a detachable header, allowing the disassembled harvester to be easily moved by manual carrying.

[0004] However, while the aforementioned harvester with a detachable header solves the problem of disassembling and transferring the header as a whole, in actual use, the header's intermediate cover is prone to wear and blockage due to direct contact with materials and impurities, requiring frequent individual disassembly and maintenance. Existing header intermediate covers mostly adopt an integrated fixed or multi-bolt fastening structure, and no quick disassembly and connection scheme has been developed to adapt to the intermediate cover. As a result, the disassembly and assembly of the intermediate cover requires multiple tools and the disassembly steps are cumbersome, making it difficult to meet the actual needs of efficient maintenance, and thus affecting harvesting efficiency.

[0029] Example 1

[0030] The quick-release connection structure of the cutter head intermediate cover provided in this embodiment is as follows: Figures 1-6 As shown, it includes: a header body 1, a cutter 102 inside the header body 1, sliding holes 302 on both sides of the inner wall of the header body 1, and disassembly / assembly components 2 installed and removed in the two sliding holes 302; a screw conveyor 103 inside the header body 1, with the disassembly / assembly components 2 covering the upper end of the screw conveyor 103. The cutter 102 is located inside the header body 1, and a feed lifter 101 is located at the upper end of the cutter 102. The upper surface of the header body 1 has locking grooves 3 at both ends, and insertion holes 301 on both sides of the header body 1 penetrate the locking grooves 3. A sliding rod 303 is fixedly installed on the lower surface of the inner wall of the sliding holes 302.

[0031] Through the design of the disassembly and assembly component 2, the snap-fit ​​groove 3, the sliding rod 303, and the insertion hole 301, the disassembly and assembly component 2 can be precisely guided by the sliding rod 303 in the sliding hole 302 during installation, ensuring that the installation position is aligned. Then, it is snapped and fixed to the disassembly and assembly component 2 through the snap-fit ​​groove 3. The components of the disassembly and assembly component 2 inserted in the insertion hole 301 can be effectively locked and fixed, ensuring a stable connection. During disassembly, the bolts can be unscrewed, and then the disassembly and assembly component 2 can be pulled out along the sliding rod 303, thereby eliminating the disassembly process and effectively improving the convenience of maintenance operations.

[0032] Example 2

[0033] The quick-release connection structure of the cutter head intermediate cover provided in this embodiment is as follows: Figures 3-6 As shown, the assembly includes: The disassembly and assembly component 2 includes an intermediate cover 201, which is disassembled and installed inside the cutter body 1. Both ends of the upper surface of the intermediate cover 201 are fixedly mounted with snap-fit ​​blocks 204, which snap into snap-fit ​​grooves 3. Each side of the snap-fit ​​block 204 has another insertion hole 301 corresponding to the insertion hole 301 of the cutter body 1. Insertion plates 205 are inserted into each of the two insertion holes 301. The surfaces of the insertion plates 205 and the snap-fit ​​blocks 204 have the same first threaded hole, and a fastening bolt 207 is threaded into the first threaded hole. Sliding blocks 202 are fixedly installed on the lower half of both sides of the intermediate cover 201. The sliding blocks 202 are sleeved on one end of the outer surface of the sliding rod 303 and slidably installed in the sliding hole 302. Sleeve blocks 203 are fixedly installed on both ends of the upper surface of the intermediate cover 201. The lower surface of the sleeve block 203 has a through hole adapted to the sliding rod 303, so that the intermediate cover 201 can drive the sleeve block 203 to be sleeved in the upper half of the sliding rod 303 through the through hole. The upper surfaces of the sliding rod 303 and the sleeve block 203 have the same second threaded hole, and the second threaded hole is threaded with a wing bolt 206. A fixing plate 208 is fixedly installed on the outer surface of the wing bolt 206. An extension rod 209 is fixedly installed on one side of the fixing plate 208. A corrugated block 210 is fixedly installed on the lower surface of the extension rod 209. Rubber blocks are glued to both sides of the snap-fit ​​block 204 and the sleeve block 203.

[0034] Through the design of the extension rod 209, sleeve block 203, intermediate cover 201, sliding block 202, and snap-fit ​​block 204, during installation, the sliding blocks 202 installed on both sides of the intermediate cover 201 are aligned with the sliding rod 303, so that they slide and fit around the sliding rod 303, forming a two-way guiding structure. Afterwards, when the intermediate cover 201 is slidably installed at the bottom of the sliding hole 302 via the sliding blocks 202, the sleeve block 203 installed on its upper surface can fit around the upper outer area of ​​the sliding rod 303 through the through hole on its lower surface, reducing the entry of external impurities into the sliding hole 302 during harvesting. The snap-fit ​​block 204 can snap into the snap-fit ​​groove 3, further enhancing the connection stability. Finally, the wing bolt 206 is manually tightened to reinforce the connection between the sleeve block 203 and the sliding rod 303, preventing... The intermediate cover 201 moves axially along the sliding rod 303, improving the vibration resistance of the structural connection. The insertion plate 205 is inserted into the insertion hole 301 between the cutter body 1 and the snap-fit ​​block 204, and the tightening bolt 207 is screwed into the first threaded hole, which facilitates connection and fixation. When the wing bolt 206 is screwed in, the corrugated block 210 installed on the lower surface of the extension rod 209 installed on one side increases the friction. The rubber blocks on both sides of the snap-fit ​​block 204 and the sleeve block 203 can fill the assembly gap, prevent foreign objects from entering the hole, and reduce the vibration during harvesting. When disassembling the connection, simply unscrew the wing bolt 206 and the tightening bolt 207, and the intermediate cover 201 can be pulled out upward along the sliding rod 303 without disassembling the rest of the structure, reducing the cumbersome steps, realizing quick disassembly, and greatly reducing maintenance time.

[0035] In summary, the quick-disassembly connection structure of the cutter intermediate cover provided in this embodiment has the following advantages: by using the sliding hole 302, the snap-fit ​​groove 3 and the disassembly and assembly component 2 together, disassembly and assembly can be completed without the need for multiple tools, and the connection strength can be ensured during connection, so as to realize the quick disassembly and assembly of the intermediate cover 201 and avoid the impact of cumbersome maintenance on harvesting efficiency.

[0036] In use, align the sliding blocks 202 on both sides of the intermediate cover 201 with the sliding rod 303 in the sliding hole 302 of the cutter body 1, and slide them down along the sliding rod 303 to the installation position, so that the snap-fit ​​block 204 of the intermediate cover 201 snaps into the snap-fit ​​groove 3 of the cutter body 1. The sleeve block 203 is sleeved on the upper half of the sliding rod 303 through the through hole. Then, insert the fixing plate 205 into the fixing hole 301 of the cutter body 1 corresponding to the snap-fit ​​block 204, screw in the fixing bolt 207 to lock it, and then tighten the wing bolt 206 to fix the sleeve block 203. When disassembling, loosen the wing bolt 206 and the fixing bolt 207 in the opposite direction, pull out the fixing plate 205, and pull out the intermediate cover 201 upward along the sliding rod 303. The disassembly and assembly are completed through the sliding fit and the insertion, pulling and twisting actions between the components.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
