Description

Technical Field

[0001] This utility model relates to the technical field of double-disc trenchers, specifically to an elastic sludge scraping mechanism inside a double-disc trencher. Background Technology

[0002] Double-disc furrow openers are widely used in agricultural operations such as sowing and fertilization due to their advantages of good furrowing quality and strong adaptability. However, in actual operation, especially in environments with high soil moisture, soil easily adheres to the inner wall of the double-disc furrow opener. As the amount of soil adhering to the surface increases, the furrowing depth of the opener becomes shallower and the furrowing trajectory deviates, seriously affecting the quality and efficiency of the operation.

[0003] In existing technologies, the sludge scraping mechanism of double-disc trenchers is mostly a rigid structure, which has the following problems: First, the fit between the scraper blade and the inner wall of the disc is difficult to adjust. If the fit is too loose, the sludge scraping will not be thorough, and if the fit is too tight, it will easily cause severe friction between the two, shortening the service life of the components. Second, when encountering hard lumps or impurities in the soil, the rigid sludge scraping mechanism lacks buffering capacity, which can easily lead to deformation of the scraper blade or damage to the disc, increasing maintenance costs. Third, the installation structure of some sludge scraping mechanisms is complex, making disassembly and maintenance inconvenient and affecting the continuous operation of the equipment.

[0004] To address the shortcomings of the existing technology, this utility model proposes an elastic sludge scraping mechanism inside a double-disc trencher. Through the elastic structural design, the scraper blades are flexibly fitted to the inner wall of the discs, balancing thorough sludge scraping with component protection. At the same time, the installation structure is optimized to improve the stability and ease of maintenance of the mechanism. Utility Model Content

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] This utility model provides the following technical solution: The elastic mud scraping mechanism inside the double disc trencher provides elastic mud scraping and high fit during use: Through the elastic action of the return spring, the mud scraper can always be flexibly fitted with the inner wall of the disc trencher, which not only ensures the thoroughness of mud removal, but also avoids wear caused by rigid contact, and extends the service life of the disc and the mud scraper.

[0029] Limit protection and strong stability: The inclined limit blocks on both sides of the mounting frame (with an included angle of 100°±5°) can accurately limit the rotation range of the rotating rod, preventing the scraper from detaching from the inner wall of the disc due to excessive rotation or excessive compression of the disc, thus improving the stability of the mechanism during operation.

[0030] Figures 1-4 The diagram shown is a structural schematic of the first embodiment of the elastic sludge scraping mechanism inside the double-disc trencher of this utility model. Please refer to [link / reference]. Figures 1-4 The elastic sludge scraping mechanism inside the double-disc trencher of this embodiment includes a trencher mounting rod 100 as its main body.

[0031] A disc trencher 110 and a mounting frame 120 are mounted on the trencher mounting rod 100. Limiting blocks 130 are installed on both sides of the mounting frame 120. The mounting frame 120 is connected to the mounting platform 150 by mounting bolts 140. A rotating groove 160 is provided on the mounting platform 150. A rotating rod 170 is rotatably connected in the rotating groove 160. A scraper 180 is installed below the bottom of the rotating rod 170. A return spring 190 is provided on the inner side of the scraper 180.

[0032] The disc trencher 110 consists of two discs located on both sides of the mounting rod. The two discs rotate synchronously to perform trenching operations.

[0033] The mounting bracket 120 has an L-shaped structure and is located between the two disc trenchers 110. The L-shaped structure design can provide a stable mounting base for subsequent components without affecting the rotation of the discs.

[0034] Limiting blocks 130 are installed on both sides of the mounting frame 120. The limiting blocks 130 are inclined and the angle between them and the mounting frame 120 is 100°±5°. They are used to limit the rotation range of the subsequent rotating parts and prevent excessive rotation from causing the scraper 180 to detach from or squeeze the disc.

[0035] The mounting bracket 120 is connected to the mounting platform 150 by mounting bolts 140. The connection method of the mounting bolts 140 facilitates the disassembly and position adjustment of the mounting platform 150.

[0036] The mounting platform 150 is provided with a rotating groove 160, and a rotating rod 170 is rotatably connected in the rotating groove 160. The rotating rod 170 can rotate flexibly along the trajectory of the rotating groove 160 to adapt to the rotation arc of the disc trencher 110.

[0037] A scraper 180 is installed below the bottom of the rotating rod 170. The scraper 180 is inclined and contacts the inner wall of the disc trencher 110. The inclination angle is adapted to the curvature of the inner wall of the disc to ensure that the mud adhering to the inner wall is completely removed.

[0038] There are two scraper blades 180, which correspond to the disc groovers 110 on both sides respectively. The two ends of the return spring 190 are connected to the inner walls of the two scraper blades 180. The return spring 190 provides continuous elastic tension to the scraper blades 180, so that the scraper blades 180 always fit against the inner wall of the disc. At the same time, it can generate buffer deformation when encountering impurities to avoid damage to the parts.

[0039] Ditcher mounting rod 100: Made of high-strength alloy steel, with a diameter of 30-40mm, and the length is set according to the installation requirements of the agricultural equipment frame to ensure sufficient support strength;

[0040] Disc trencher 110: Made of wear-resistant steel, with a diameter of 350-500mm. Two discs are symmetrically installed on both sides of the trencher mounting rod 100. The discs are connected to the mounting rod by bearings to ensure that the discs can rotate flexibly.

[0041] Mounting bracket 120: Made of L-shaped steel plate with a thickness of 5-8mm, it is fixed to the trencher mounting rod 100 by welding or bolts and is located between two discs. The transverse section of the L-shaped mounting bracket is used to install the limiting block 130, and the longitudinal section is used to connect the mounting platform 150.

[0042] Limiting block 130: Made of rectangular steel plate with a thickness of 5mm, it is installed on both sides of the mounting bracket 120 by welding. During welding, ensure that the included angle between the limiting block 130 and the mounting bracket 120 is 100°±5°. The length of the limiting block 130 is 30-50mm, which is used to prevent the rotating rod 170 from rotating excessively.

[0043] Mounting platform 150 and rotating rod 170: Mounting platform 150 is a rectangular iron block, which is connected to mounting bracket 120 by M10-M12 mounting bolts 140. The width of the rotating groove 160 on mounting platform 150 is 1-2mm larger than the diameter of rotating rod 170. Rotating rod 170 is made of round steel with a diameter of 8-12mm. The top of rotating rod 170 is connected to rotating groove 160 by a pin, and the bottom is welded to scraper 180.

[0044] Scraper blade 180 and return spring 190: Scraper blade 180 is made of wear-resistant rubber or polyurethane material with a thickness of 10-15mm. The tilt angle is adapted to the curvature of the inner wall of the disc (usually 15°-30°). The two scraper blades 180 correspond to the two discs on both sides respectively. The return spring 190 is a cylindrical helical spring with an elastic coefficient of 5-10N / mm. The two ends of the spring are connected to the inner wall of the two scraper blades 180 by hooks or welding.

[0045] Combination Figures 1-4 The working principle of the elastic sludge scraping mechanism inside the double-disc trencher 110 in this embodiment is as follows:

[0046] When the agricultural equipment drives the double-disc furrow opener 110 to perform furrowing operations, the two discs rotate synchronously around the furrow opener mounting rod 100, and the soil is cut open to form trenches under the action of the discs. During this process, some soil will adhere to the inner wall of the discs.

[0047] The return spring 190 continuously applies an elastic tension to the two scraper blades 180, so that the scraper blades 180 always adhere to the inner wall of the disc.

[0048] As the disc rotates, the soil adhering to its inner wall is scraped off by the inclined scraper 180, and the scraped soil naturally falls into the trench.

[0049] When the inner wall of the disc encounters a hard block or impurity, the scraper 180 is squeezed and drives the rotating rod 170 to rotate slightly along the rotating groove 160 of the mounting platform 150. At the same time, the return spring 190 deforms to provide a buffer space for the impurities to pass through, thus preventing damage to the scraper 180 or the disc.

[0050] Once the impurities have passed through, the return spring 190 returns to its original deformation, causing the scraper 180 and the rotating rod 170 to return to their original positions and re-fit against the inner wall of the disc to continue the scraping operation.

[0051] The limiting blocks 130 on both sides of the mounting bracket 120 can prevent the rotating rod 170 from exceeding the preset range due to excessive buffering, ensuring that the scraper 180 is always in the effective scraping position.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
