Description

TECHNICAL FIELD

[0001] The utility model relates to the field of turnover plough of seeding machine, especially to a single wire rod adjustment plough width turnover plough. BACKGROUND

[0002] The existing adjustable width turnover plough is generally adjusted by the form that double wire rods cooperate with I-beam to adjust the angle of the turnover plough girder, thereby adjusting the ploughing width, and a small part is adjusted by directly adjusting the longitudinal distance of the multiple plough bodies installed on the girder to adjust the ploughing width. The adjustment mode of the double wire rod processing girder adjusts the ploughing width of the turnover plough by adjusting the angle of the quadrilateral, the principle is relatively complex, and the hinge precision of the four corners of the quadrilateral needs to be accurately controlled, and the mode of adjusting the longitudinal distance of different plough bodies to change the ploughing width of the plough makes the operation cost of the operator larger. Moreover, the structure of the above two existing modes is relatively bulky, which leads to the excessive large preparation quality of the turnover plough, and the horse power section of the tractor must be larger. SUMMARY

[0003] The utility model discloses a kind of single wire rod adjustment plough width turnover plough, simplify turnover plough structure, reduce preparation quality.

[0004] The utility model discloses a kind of single wire rod adjustment plough width turnover plough, simplify turnover plough structure, reduce preparation quality.

[0005] Preferably, the middle part of the girder is provided with a depth limiting wheel assembly, the depth limiting wheel assembly includes a depth limiting wheel and a bracket, the bracket or the girder is provided with a plurality of adjacent mounting holes, by aligning and connecting the mounting holes at different positions of the bracket or the girder, the installation angle of the depth limiting wheel relative to the girder can be adjusted.

[0006] According to the above technical solution, the utility model has the beneficial effects of:

[0007] The utility model discloses a big beam and multiple plow bodies can be adjusted to the angle relative to plow head through the telescopic adjustment of screw rod, then through the change of the mounting hole for alignment connection on plow body and big beam, the installation angle of plow body relative to big beam can be adjusted, finally the width of whole plow can be adjusted, the screw rod can be fine -tuned in the operation process, makes the advancing direction of plow and tractor traction on the same line, can adapt to the change of different soil, plays the best performance of plow, the single screw rod adjustment plough width mode not only simple structure, and the installation precision requirement is lower, effectively alleviates the preparation quality of hydraulic turnover plow, can adapt to the tractor of lower horsepower section. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 It is top view schematic drawing of the utility model.

[0009] Mark in drawing: 1, plow head, 2, turnover arm, 3, turnover cylinder, 4, big beam, 5, plow body, 6, adjustment screw rod, 7, depth wheel assembly. DETAILED DESCRIPTION

[0010] Referring to the drawings, the specific implementation is as follows:

[0011] As Figure 1 Indicated, a single screw rod adjustment plough of plough width, including plow head 1, turnover arm 2, big beam 4, adjustment screw rod 6 and multiple plow bodies 5, plow head 1 is connected with turnover arm 2 rotationally, still be connected with turnover cylinder 3 between plow head 1 and turnover arm 2, for driving turnover arm 2 to plow head 1 and turning over.In use, tractor is hung down and is connected with the quick hanging structure of plow head 1, and the waist type hole of plow head 1 is hung with tractor pull rod, provides traction power for plow.Plow head 1 can also set up horizontal adjustment seat, according to different ploughing depth corresponds to different height, plow is adjusted horizontally.

[0012] As Figure 1 Indicated, the end of turnover arm 2 away from plow head 1 is hinged with the end of big beam 4, multiple plow bodies 5 are connected with big beam 4 respectively and are spaced apart along the length direction of big beam 4, multiple adjacent mounting holes are set up on plow body 5 or big beam 4, by making the mounting hole of different positions on plow body 5 or big beam 4 alignment connection, the installation angle of plow body 5 relative to big beam 4 can be adjusted.Both ends of adjustment screw rod 6 are hinged with turnover arm 2 and big beam 4 respectively, by the telescopic movement of adjustment screw rod 6, big beam 4 can be driven to rotate around turnover arm 2, thereby changing the angle of big beam 4 relative to plow head 1, namely the angle of big beam 4 relative to the advancing direction of tractor is changed.Then again through the change of mounting hole mode corresponding adjustment plow body 5 relative to big beam 4 angle, the plowing direction of multiple plow bodies 5 can be made with the advancing direction of tractor consistent, and the plough width of multiple plow bodies 5 is changed.

[0013] As Figure 1As shown, the middle part of the beam 4 is provided with a depth wheel assembly 7, which comprises a depth wheel and a bracket. The bracket is provided with a plurality of adjacent mounting holes on the beam 4. By aligning the mounting holes at different positions on the bracket or the beam 4, the installation angle of the depth wheel relative to the beam 4 can be adjusted. The adjustment mode of the depth wheel assembly 7 is the same as the adjustment mode of the plow body 5. After the beam 4 is rotated by the adjusting screw 6, the angle of the depth wheel assembly 7 relative to the beam 4 is adjusted by changing the mounting holes, so that the depth wheel assembly 7 is kept consistent with the advancing direction of the tractor.

[0014] After the working width is determined, the adjusting screw can be adjusted according to the ground conditions to make the advancing direction of the plow consistent with the traction direction of the tractor, so that the plow can play the best performance.

[0015] The above only describes one embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
