Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a reversible plow capable of adjusting tillage width by partition. Background Art

[0002] The relationship between the first plowshare of the reversible plow and the wheelbase of the tractor is more important, and usually meets two principles: (1) Avoid interference: Since the first plowshare of the reversible plow has different wheelbases with different tractor models and specifications during operation, the position of the first plowshare and the wheelbase must be considered when designing and using the corresponding reversible plow. For example, if a tractor with a narrow wheelbase is used with an inappropriate reversible plow, the first plowshare will produce uneven furrows when plowing wide or narrow.

[0003] (2) Reasonable coverage of cultivated land width: The position of the first plowshare combined with the wheelbase should be able to achieve reasonable coverage of cultivated land width and ensure the continuity and integrity of land plowing. Generally speaking, during plowing, the first plowshare should be able to cut into the land and start plowing on both sides of the space occupied by the tractor wheelbase to avoid missing plowing or inconsistent plow width.

[0004] The reversible plows produced by different manufacturers may have differences in the plow body structure, the size of the first plowshare and the relative position layout even if they have the same tillage width. When they are matched with tractors with specific wheelbases, they need to be adjusted according to the actual situation. For example, the first plowshare of the reversible plow can be adjusted to match the tractor wheelbase, and the other plowshares on the beam can also be adjusted in sections. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a reversible plow capable of adjusting the tillage width by partitions to adapt to tractors with different wheelbases.

[0006] The technical solution adopted by the present invention is: a reversible plow with zoned adjustment of tillage width, comprising a plowshare assembly, a reversing block, a reversing block splint, a supporting wheel assembly, a beam, a head plowshare and a plurality of tail plowshares; the middle part of the plowshare assembly is connected with the reversing block through a bearing; the reversing block is in the shape of a "7"; the end of the reversing block is hinged at the front end of the beam; an adjusting screw is arranged between the reversing block and the beam; a reversing block splint is arranged on the upper and lower surfaces of the reversing block; the reversing block splint is connected with the head plowshare through a head plowshare adjustment plate; a plurality of the tail plowshares are arranged on the beam in sequence; the supporting wheel assembly is arranged in the middle part of the beam.

[0007] Furthermore, a plurality of groups of first plowshare adjustment holes are formed on the flip block clamping plate, and the first plowshare adjustment holes are connected to the adjustment plate positioning holes on the first plowshare adjustment plate through pins.

[0008] Furthermore, two ends of the adjusting screw rod are respectively hinged to one end of the flip block and the beam, and the swing angle of the beam relative to the flip block is controlled by adjusting the adjusting screw rod.

[0009] Furthermore, the support wheel assembly can support the beam and can rotate 360 ​​degrees and adjust the support height.

[0010] Furthermore, the tailshare is fixed to the beam by two pins, wherein a plurality of angle adjustment holes are provided at the position of one of the pins, and the angle of the tailshare relative to the beam is controlled by different angle adjustment holes.

[0011] Furthermore, the flip block clamp is provided with a plurality of beam angle positioning holes, through which pins pass through the flip block clamp and the beam to fix the swing angle of the beam.

[0012] The beneficial effects of the present invention are as follows: the present invention can quickly adjust the distance between the front plowshare and the tractor wheel, avoid mismatching of the tillage width between the front plowshare and the tractor wheel, and can adapt to different tractor wheel widths.

DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 to Figure 2As shown, the present invention is a reversible plow for adjusting the plow width by partition, comprising a plowshare assembly 1, a reversing block 2, a reversing block clamping plate 3, a head plowshare 4, a supporting wheel assembly 6, a beam 7 and three tail plowshares 12; the middle part of the plowshare assembly 1 is connected to the reversing block 2 through a bearing, and the plowshare assembly 1 is provided with a reversing oil cylinder to drive the reversing block 2 to rotate relative to the plowshare assembly 1, playing the basic function of the reversing plow. The reversing block is in the shape of a "7"; the end of the reversing block 2 is hinged to the front end of the beam 7, so that the reversing block 2 drives the beam 7 to rotate together. An adjusting screw rod 5 is arranged between the reversing block 2 and the beam 7, and the two ends of the adjusting screw rod 5 are respectively hinged to one end of the reversing block 2 and the beam 7, and the swing angle of the beam 7 relative to the reversing block 2 is controlled by adjusting the screw rod 5. The reversing block clamping plates 3 are arranged on the upper and lower surfaces of the reversing block 2; the head plowshare 4 is connected to the reversing block clamping plate 3 through the head plowshare adjusting plate 8. Three beam angle positioning holes 14 are also provided on the flip block clamping plate 3 , through which pins pass through the flip block clamping plate 3 and the beam 7 to fix the swing angle of the beam 7 .

[0016] like Figure 3 As shown, in this embodiment, three groups of front plowshare adjustment holes 10 are sequentially opened on the flip block clamping plate 3 in a horizontal direction, so that the front plowshare adjustment holes 10 are connected to the corresponding adjustment plate positioning holes 9 on the front plowshare adjustment plate 8 through pins. According to the different wheelbases of the tractor, the position of the front plowshare 4 is adjusted, and then the distance between the front plowshare 4 and the tractor tire is adjusted. Three tail plowshares 12 are sequentially arranged on the beam 7. The tail plowshare 12 is fixed to the beam 7 through two front and rear pins, and four angle adjustment holes 13 are arranged at the rear pin position. The angle of the tail plowshare 12 relative to the beam 7 is controlled by different angle adjustment holes 13 to achieve the purpose of coordinating the adjustment of the front plowshare 4; and the front plowshare 4 and the tail plowshare 12 can be adjusted independently in different areas, which greatly improves the flexibility of adjustment. The support wheel assembly 6 is arranged in the middle of the beam 7 to provide support for the entire beam, and can rotate 360 ​​degrees and adjust the support height.

[0017] The present invention can quickly adjust the distance between the front plowshare 4 and the tractor wheel through the pin, so as to avoid the mismatch between the front plowshare 4 and the tractor wheel plowing width, so as to adapt to different tractor wheel widths. If the front plowshare 4 does not need to be adjusted during plowing, the angle of the rear plowshare 12 can be adjusted separately, which saves time and effort.
