[0002] The disc trencher is a powerful and efficient tool for farmland and engineering construction. It uses a rotating disc as its digging tool, driven by powerful motors to easily create neat and even trenches in the ground. Whether laying irrigation pipes or cables, or carrying out drainage and fertilization operations in orchards and farmland, the disc trencher can handle the task quickly and significantly improve work efficiency. It is easy to operate, requiring only simple training, and is equipped with safety devices to ensure operational safety. With its high efficiency, flexibility, and safety, the disc trencher has become an indispensable piece of equipment in modern agriculture and engineering construction.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 , 2 and Figure 4 As shown, this utility model provides a technical solution for a double-sided adjustable trenching machine disc, including a trenching machine frame 1, a mounting base 2 fixedly installed on the trenching machine frame 1, a reduction gearbox 3 fixedly installed on the mounting base 2, an input shaft 4 connected to the reduction gearbox 3, an adjustment hole 7 opened on the upper surface of the reduction gearbox 3, a disc assembly 5 installed on the reduction gearbox 3, the disc assembly 5 including a drive shaft 502 installed on the reduction gearbox 3, adjustable support columns 505 movably installed at both ends of the drive shaft 502, and an adjustment mechanism 6 provided inside the drive shaft 502. The disc assembly 5 can quickly open trenches on the ground, and the adjustment mechanism 6 can adjust the distance between the trenching discs 501 to facilitate the opening of trenches of different widths.

[0023] Such as 2 and Figure 3 As shown, the disc assembly 5 includes a drive shaft 502 mounted on the gearbox 3. Adjustment supports 505 are movably mounted at both ends of the drive shaft 502. A trenching disc 501 is fixedly mounted at the end of the adjustment support 505. A rack groove 503 is provided inside the drive shaft 502. A storage chamber 507 is provided at both ends of the drive shaft 502. A limiting foot 506 is fixedly mounted on the adjustment support 505. A movable groove 504 is provided on the inner wall of the storage chamber 507. The limiting foot 506 is slidably mounted in the storage chamber 507 through the movable groove 504. A bearing is provided on the drive shaft 502. The drive shaft 502 is movably mounted on the gearbox 3 through the bearing. The gearbox 3 is mounted on the trenching machine frame 1 through the mounting base 2.

[0024] Specifically, the engine can drive the input shaft 4 to rotate. After the input shaft 4 rotates, it will drive the gear inside the reduction gearbox 3 to rotate, which will drive the drive shaft 502 to rotate. The rotating drive shaft 502 will drive the adjusting support 505 to rotate, and the rotating adjusting support 505 will drive the trenching disc 501 to rotate, thereby quickly opening trenches on the ground.

[0025] like Figure 2 , 4 and Figure 5 As shown, the adjusting mechanism 6 includes an adjusting rack 601 movably installed in the rack groove 503, with the end of the adjusting rack 601 fixed to the adjusting support column 505. An adjusting gear 606 is movably installed between the adjusting racks 601. A worm gear 603 is connected to the upper end of the adjusting gear 606. A worm 604 is movably installed on one side of the worm gear 603. A hexagonal threaded sleeve 602 is fixedly installed at the end of the worm 604. A positioning shaft 605 is provided on the adjusting gear 606. The adjusting gear 606 is movably installed between the adjusting racks 601 through the positioning shaft 605, and the adjusting gear 606 meshes with the adjusting rack 601.

[0026] Specifically, the worm gear 603 can drive the worm wheel 604 to rotate. After the worm gear 604 rotates, it will drive the positioning shaft 605 to rotate, thereby causing the adjusting gear 606 to rotate. After the adjusting gear 606 rotates, it will drive the adjusting racks 601 on both sides to move back and forth, thereby driving the adjusting support 505 to extend and retract, adjusting the distance between the grooved discs 501, so as to facilitate the opening of grooves of different widths.

[0027] Working principle: Before use, the grooved disc 501 can be rotated to rotate the drive shaft 502, aligning the hexagonal threaded sleeve 602 on the drive shaft 502 with the adjusting hole 7. After the hexagonal threaded sleeve 602 is aligned with the adjusting hole 7, it can be rotated using a hexagonal wrench. Rotating the hexagonal threaded sleeve 602 will drive the worm 603 to rotate. Since the worm 604 is equipped with a retainer, the worm 604 is movably mounted on one side of the worm wheel 603 through the retainer, and the worm wheel 603 meshes with the worm 604. Therefore, the rotation of the worm 603 will drive the rotation of the worm wheel 604, and the rotation of the worm wheel 604 will drive the rotation of the positioning shaft 605. Since the adjusting gear 606 is equipped with a positioning shaft 605, the adjusting gear 606 is movably mounted between the adjusting rack 601 through the positioning shaft 605, and the adjusting gear 606 meshes with the adjusting rack 601. When combined, the positioning shaft 605 rotates, which in turn drives the adjusting gear 606 to rotate. The adjusting gear 606 then drives the adjusting racks 601 on both sides to move back and forth. The moving back and forth movement of the adjusting racks 601 then drives the adjusting support 505 to extend and retract. During the extension and retraction of the adjusting support 505, the grooving disc 501 moves back and forth, thereby adjusting the distance between the grooving discs 501 to facilitate the creation of grooves of different widths. After the distance between the grooving discs 501 is adjusted, the input shaft 4 can be driven to rotate by the engine. The rotation of the input shaft 4 then drives the gear inside the reduction gearbox 3 to rotate, which in turn drives the drive shaft 502 to rotate. The rotation of the drive shaft 502 then drives the adjusting support 505 to rotate, which in turn drives the grooving disc 501 to rotate, thus quickly creating grooves on the ground.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
