Description

Technical Field

[0001] The utility model belongs to the technical field of plow equipment, in particular to a disc plow which is easy to adjust. Background Art

[0002] When the plowing equipment is working, it is necessary to adjust the extension depth of the equipment according to the state of the soil to avoid the soil being too hard and causing damage to the plow blade; at the same time, it is also necessary to avoid the soil being too wet and the plowing depth being too shallow, resulting in the inability to loosen the soil. The plowing depth of existing agricultural devices mainly relies on adjusting the traction force of the traction equipment, or adjusting the height of the plowing equipment bracket from the ground. Although the above two methods can adjust the plowing depth, it is still limited by the size of the plow blade. When the plowing depth needs to be increased, if it exceeds the effective range of the plow blade, the plow blade can only be replaced. Since the plow blade replacement process is cumbersome and laborious, it is necessary to design a disc plow that is easy to adjust to meet market demand. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a disc plow that is convenient for adjusting the plowing depth to solve the above-mentioned problems.

[0004] The cam is provided with a plurality of T-shaped guide slots, each of which is retractable in the T-shaped guide slots, and a plow blade is provided on the outer end of the plow blade. A coaxial adjusting dial is provided on one side of the disc, and a through hole is provided on the axis of the adjusting disc, and a cover ring rotatably connected is provided in the through hole, and a plurality of fixing bolts connected to the adjusting disc are provided on the cover ring; a spiral groove is provided on the inner side of the adjusting disc, and the T-shaped guide slot opens on one side close to the adjusting disc, and each of the slides is provided with a slider extending from the T-shaped guide slot opening, and the slider is adapted to the spiral groove, and a gear ring is provided in the adjusting disc, and a gear meshing with the gear ring is provided on the disc, and a rotating shaft passing through the disc is provided on the gear, and a hexagonal column is provided on the protruding end of the rotating shaft, and a locking portion is provided between the gear and the disc.

[0005] Furthermore, the locking portion is a tightening bolt, which passes through the disc from one side of the hexagonal column and has an end abutting against the end face of the gear.

[0006] Furthermore, the slide plate is provided with scale lines.

[0007] Furthermore, the plowshares are each provided with a slot end adapted to the end of the slide plate, the slot end is plugged into the slide plate, and a connecting bolt is provided between the slot end and the slide plate for locking.

[0008] Furthermore, the adjusting turntable is provided with a first dustproof ring that matches the circular disc, and the outer ring of the cover ring is provided with a second dustproof ring that matches the adjusting turntable.

[0009] Compared to existing technologies, this disc plow can adjust the extension length of all slides by rotating the adjustment dial, allowing the plowing depth of the coulters to be adjusted simultaneously without having to remove the coulters. In summary, this disc plow not only adjusts the extension depth of the equipment according to soil conditions, but also does so more efficiently and with less effort.

[0018] In order to better understand the present invention, Figures 1 to 7 The embodiments of the present invention will be explained in detail.

[0019] It should be noted that the directions “front, back, left, right, up, down” mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up and down” are used as the reference.

[0020] See also Figures 1 to 7The utility model is a disc plow that is easy to adjust, comprising a disc 1, on which a plurality of T-shaped slide grooves 2 are arranged in an axially rotating array, each of which is provided with a slide plate 3 that is telescopically arranged in the T-shaped slide groove 2, and a detachably connected plow blade 4 is provided at the outer end of the slide plate 3.

[0021] A coaxial adjusting dial 5 is provided on one side of the disc 1 , a through hole 6 is provided at the axis of the adjusting dial 5 , a rotatably connected cover ring 7 is provided in the through hole 6 , and a plurality of fixing bolts 8 connected to the adjusting dial 5 are provided on the cover ring 7 .

[0022] A spiral groove 9 is welded to the inner side of the adjusting dial 5, and the spiral groove 9 is coaxially arranged with the adjusting dial 5. The T-shaped slide groove 2 is open on the side close to the adjusting dial 5, and each of the slide plates 3 is provided with a slider 10 extending out of the opening of the T-shaped slide groove 2, and the slider 10 is adapted to the spiral groove 9. A ring gear 11 is provided in the adjusting dial 5, and a gear 12 meshing with the ring gear 11 is provided on the disc 1. A rotating shaft passing through the disc 1 is provided on the gear 12, and a hexagonal column 13 is provided at the protruding end of the rotating shaft. A locking portion is provided between the gear 12 and the disc 1, and the locking portion is used to lock the rotation of the gear 12.

[0023] The preferred technical solution in this embodiment is as follows Figure 4 As shown in the figure, the locking portion is a tightening bolt 14, which passes through the disc 1 from one side of the hexagonal column 13 and has its end abutted against the end face of the gear 12; by tightening the tightening bolt 14 so that its end abuts against the end face of the gear 12, the gear 12 cannot rotate, and the adjusting dial 5 cannot rotate at the same time; when it is necessary to adjust the slide plate 3 to extend to a certain length, the tightening bolt 14 is reversed to loosen it, thereby releasing the restriction on the gear 12 and allowing the gear 12 to rotate normally.

[0024] The preferred technical solution in this embodiment is to facilitate the confirmation of the extended length of the slide plate 3. Figure 6 As shown in FIG, the slide plate 3 is provided with scale lines 15.

[0025] The preferred technical solution in this embodiment is that the plow blade 4 may be damaged due to the presence of stones in the ground, and the plow blade 4 and the slide plate 3 are designed to be detachable and assembled. Figure 6 As shown in the figure, the coulters 4 are provided with slot ends 16 adapted to the ends of the slide plates 3 , the slot ends 16 are plugged into the slide plates 3 , and connecting bolts 17 are provided between the slot ends 16 and the slide plates 3 for locking.

[0026] The preferred technical solution in this embodiment is to avoid dust erosion and affect the rotation of the adjustment dial 5. Figure 7As shown in , the adjusting dial 5 is provided with a first dustproof ring 18 that matches the disc 1 , and the outer ring of the cover ring 7 is provided with a second dustproof ring 19 that matches the adjusting dial 5 .

[0027] When it is necessary to adjust the plowing depth, the method of using the present invention is as follows: first, loosen the tightening bolt 14 so that its end no longer abuts the gear 12, thereby releasing the locking state of the gear 12; then, use an external hexagonal wrench to connect with the hexagonal column 13, and use the external hexagonal wrench to rotate the hexagonal column 13, so that the gear 12 rotates and drives the adjusting dial 5 to rotate. During this period, as the spiral groove 9 in the adjusting dial 5 rotates, the slider 10 in the spiral groove 9 drives its slide plate 3 to extend and retract in the T-shaped slide groove 2, and confirms the extended length of the slide plate 3 according to the scale, and uses the extension and retraction of the slide plate 3 to adjust the coulter 4, thereby achieving the adjustment of the plowing depth; finally, tighten the tightening bolt 14 so that its end abuts against the gear 12 and then locks the gear 12, so that the gear 12 and its adjusting dial 5 cannot rotate, to ensure that the extended length of the slide plate 3 remains fixed.
