Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment, specifically relating to a reversible plow that can automatically adjust the first moldboard. Background Technology

[0002] The relationship between the first furrow of the reversible plow and the wheel track of the tractor is quite important, and it usually follows two principles:

[0003] (1) Avoiding interference: It is generally necessary to ensure that the first moldboard of the reversible plow does not collide with or interfere with the tractor wheels during operation. Different models and specifications of tractors have different wheel tracks, and the reversible plow must take into account the compatibility between the position of the first moldboard and the wheel track when it is designed and used in practice. For example, if a tractor with a narrow wheel track is paired with an improperly matched reversible plow, the first moldboard may hit the wheels during steering or other operations, affecting normal operation or even damaging the equipment.

[0004] (2) Reasonable tillage coverage: The position of the first furrow, combined with the wheel track, should be able to achieve reasonable tillage coverage, ensuring the continuity and integrity of land plowing. Generally speaking, during plowing operations, the first furrow should be able to cut into the land at just the right angle on both sides of the space occupied by the tractor wheel track to begin plowing, avoiding any missed tillage areas.

[0005] Even reversible plows with the same tillage width can differ in their plow body structure, first-furrow size, and relative positional arrangement due to different manufacturers. When using such reversible plows with tractors of a specific wheelbase, a one-size-fits-all approach is not feasible; adjustments must be made based on the actual situation. For example, if the first-furrow of a reversible plow has an adjustable mounting position, it can better adapt to tractors with various wheelbases, achieving superior compatibility. Summary of the Invention

[0006] To solve the above problems, this utility model provides a reversible plow that can automatically adjust the first moldboard to adapt to tractors with different wheel gauges.

[0007] The technical solution adopted by this utility model is as follows: a reversible plow capable of automatically adjusting the first plowshare, comprising a plow head assembly, a reversible block, a sliding block, a sliding block clamping plate, a support wheel assembly, and a main beam; the reversible block is connected to the middle of the plow head assembly via a bearing; the reversible block is disposed in the middle of the sliding block; the sliding block is T-shaped; the end of the sliding block is connected to the front end of the main beam; an adjusting screw is disposed between one side of the sliding block and the main beam; sliding block clamping plates are disposed on the upper and lower surfaces of the sliding block; a hydraulic cylinder is horizontally fixed inside the sliding block; the hydraulic cylinder is connected to the reversible block via a hydraulic rod; an extension block is disposed on the reversible block; elongated limiting holes are correspondingly disposed on the sliding block and the sliding block clamping plate; a pin passes through the limiting holes and is fixed on the reversible block and the extension block; the first plowshare is connected to the sliding block clamping plate; the support wheel assembly is disposed in the middle of the main beam.

[0008] Furthermore, the upper and lower surfaces of the sliding block and the sliding block clamping plate are provided with three sets of limiting holes for the pins on the flipping block and the extension block to pass through.

[0009] Furthermore, the two ends of the adjusting screw are respectively hinged to one end of the sliding block and the main beam, and the swing angle of the main beam relative to the sliding block is controlled by adjusting the adjusting screw.

[0010] Furthermore, the support wheel assembly can support the main beam and can rotate 360 ​​degrees and adjust the support height.

[0011] The beneficial effects of this utility model are as follows: This utility model can quickly and automatically adjust the distance between the first plowshare and the tractor wheel through the hydraulic cylinder, effectively preventing missed plowing and over-plowing. At the same time, it can adapt to different plowing resistance under different ground conditions, is compatible with tractors with various wheel gauges, and significantly improves plowing efficiency and quality.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 2 As shown, this utility model is a reversible plow capable of automatically adjusting the first plowshare, including a plowshare assembly 1, a reversible block 11, a sliding block 2, a sliding block clamping plate 3, a first plowshare 4, an adjusting screw 5, a support wheel assembly 6, and a main beam 7. The reversible block 11 is connected to the middle of the plowshare assembly 1 via a bearing. The reversible block 11 is located in the middle of the sliding block 2, which is T-shaped. The end of the sliding block 2 is connected to the front end of the main beam 7, allowing the sliding block 2 to rotate relative to the plowshare assembly 1 and drive the main beam 7 to rotate together, thus fulfilling the basic function of a reversible plow. An adjusting screw 5 is provided between one side of the sliding block 2 and the main beam 7. The two ends of the adjusting screw 5 are hinged to one end of the sliding block 2 and the main beam 7, respectively. The swing angle of the main beam 7 relative to the sliding block 2 is controlled by fine-tuning the adjusting screw 5. Sliding block clamping plates 3 are provided on the upper and lower surfaces of the sliding block 2. The support wheel assembly 6 is located in the middle of the main beam 7, providing support for the entire main beam and enabling 360-degree rotation and adjustment of the support height.

[0019] like Figure 3 and Figure 4 As shown, a hydraulic cylinder 9 and a tilting block 11 are horizontally arranged inside the sliding block 2. The hydraulic cylinder 9 is fixed inside the sliding block 2, and the hydraulic rod 10 on the hydraulic cylinder 9 is connected to the tilting block 11. An extension block 12 is provided on the tilting block 11. Three pins pass through three sets of elongated limiting holes 8 respectively set on the upper and lower surfaces of the sliding block 2 and the sliding block clamping plate 3. Two sets limit the movement of the tilting block 11, and one set limits the movement of the extension block 12. The first plowshare 4 is connected to the extension block 12. According to the different wheel track of the tractor, the first plowshare 4 is driven to move by the hydraulic cylinder 9 to adjust the position of the first plowshare 4, thereby adjusting the distance between the first plowshare 4 and the tractor tires. This effectively prevents missed tillage and over-tillage, and can adapt to different tillage resistances in different terrain conditions. It is compatible with tractors with various wheel track sizes, significantly improving tillage efficiency and quality.
