Description

Paddy-uphand field plough is ploughed the position and is regulated locking mechanism

Technical field

The utility model relates to the agricultural machinery field, is that a kind of Paddy-uphand field plough is ploughed position adjusting locking mechanism.

Background technology

It is to insert by the hand lever pin that is provided with on right towing plate to realize ploughing the position in several teeth of tooth plate and regulate that existing Paddy-uphand field plough ploughs that the position regulates.Do not have locking mechanism because existing Paddy-uphand field plough is ploughed the position adjusting, the contact of hand lever pin skids off from the tooth of tooth plate easily, causes the cultivated biased poor of plough, influences farmland quality.

Summary of the invention

Technical problem to be solved in the utility model is, provides a kind of simple in structure, easy to operate, and lock-bit is reliable, guarantees the cultivated position adjusting of the Paddy-uphand field plough of not ploughing a partially locking mechanism.

The technical scheme that solves its technical problem employing is: a kind of Paddy-uphand field plough is ploughed the position and is regulated a locking mechanism, it is included in hinged tooth plate on the left and right towing plate of plough, it is characterized in that: on right towing plate, be fixed with U type frame, be provided with pivoted arm, the head end of pivoted arm is articulated on the U type frame, in U type frame, be provided with the hand lever alligator, on the hand lever alligator, be nested with support spring, the tooth of hand lever alligator front end is meshed with the tooth of tooth plate, on pivoted arm, be hinged with pull bar, pull bar and hand lever alligator rear end are hinged, and pivoted arm is connected by position locking device with U type frame.The structure of described position locking device is, the viewport that is provided with on the latch hook that is provided with on the pivoted arm and the U type frame matches.

Paddy-uphand field plough of the present utility model is ploughed the position and is regulated locking mechanism, owing on right towing plate, be fixed with U type frame, be nested with support spring on the hand lever alligator that in U type frame, is provided with, the tooth of hand lever alligator front end is meshed with the tooth of tooth plate, the head end of pivoted arm is articulated on the U type frame, pull bar and hand lever alligator rear end hinged on pivoted arm are hinged, and pivoted arm is connected by position locking device with U type frame.Can the change by the angle of traction realize ploughing the adjusting of position, and can avoid the tooth of hand lever alligator to skid off from the tooth of tooth plate, have simple in structurely, easy to operate, lock-bit is reliable, advantage such as guarantee that Paddy-uphand field plough is not ploughed partially.

Description of drawings

Fig. 1 ploughs the position for Paddy-uphand field plough and regulates the locking mechanism schematic perspective view.

Fig. 2 is hand lever alligator 4 structure enlarged diagrams.

Fig. 3 regulates locking mechanism and Paddy-uphand field plough syndeton schematic perspective view for ploughing the position.

Among the figure: 1 tooth plate, 2 left towing plates, 3 right towing plates, 4 hand lever alligators, 5 pull bars, 6 support springs, 7U type frame, 8 viewports, 9 bearing pins, 10 little axles, 11 pivoted arms, 12 handles, 13 spacer pins, 14 latch hooks, 15 position locking devices.

Embodiment

The utility model is described in further detail to utilize drawings and Examples below.

With reference to Fig. 1 and 2, it is to be hinged with tooth plate 1 on the left and

right towing plate

2,3 of plough that Paddy-uphand field plough is ploughed position adjusting locking mechanism.Be fixed with U type frame 7 on right towing plate 3, the tooth that is positioned at hand lever alligator 4 front ends at U type frame 7 is provided with viewport 8 with the tooth place of being meshed of tooth plate 1.Be provided with pivoted arm 11, pivoted arm 11 rear ends are provided with handle 12, and the head end of pivoted arm 11 is articulated on the U type frame 7 by bearing pin 9.In U type frame 7, be provided with hand lever alligator 4, on hand lever alligator 4, be nested with support spring 6, the front end of support spring 6 contacts with U type frame 7 front aprons, and the spacer pin 13 that is provided with on the rear end of support spring 6 and the hand lever alligator 4 contacts, and the tooth of hand lever alligator 4 front ends is meshed with the tooth of tooth plate 1.Pivoted arm 11 is hinged with pull bar 5 by little axle 10, and pull bar 5 is hinged with hand lever alligator 4 rear ends.Pivoted arm 11 is connected by position locking device 15 with U type frame 7.The structure of described position locking device 15 is, the viewport 8 of setting matches on the latch hook 14 that is provided with on the pivoted arm 11 and the U type frame 7.Pivoted arm 11 and the latch hook 14 that is provided with on it can adopt overall structure.Position locking device 15 is set is for the tooth that prevents hand lever alligator 4 front ends and the tooth of tooth plate 1 and throw off, that is: 7 contrary, the extreme position that clockwise rotates of the relative U type frame of position locking device 15 locking pivoted arms 11.Therefore, according to the enlightenment that purposes and structure obtained of the utility model position locking device 15, those skilled in the art just can design other mechanism of pivoted arm 11 relative U type frame 7 locking positions without creative work.

The viewport 8 that is provided with on the U type frame 7 has dual-use function, and the one, the tooth engagement situation that can observe the tooth and the tooth plate 1 of hand lever alligator 4 front ends by viewport 8; The 2nd, the latch hook 14 of pivoted arm 11 is matched with the viewport 8 of U type frame 7, so that the locking pivoted arm is 11 contrary, the two limit positions that clockwise rotates, this moment, viewport 8 played the fore shaft effect.

With reference to Fig. 3, the U type frame 7 that Paddy-uphand field plough is ploughed position adjusting locking mechanism is weldingly fixed on the right towing plate 3 of Paddy-uphand field plough.

In the time of need ploughing the position adjusting, rotate the counterclockwise hinging pin shaft 9 of arm 11 and U type frame 7 of pivoted arm 11 is rotated, pivoted arm 11 moves after making hand lever alligator 4 by little axle 10 hinged pull bars 5, the tooth of hand lever alligator 4 front ends and the tooth of tooth plate 1 are thrown off, when reaching the needed angle of traction in cultivated position, rotate the clockwise hinging pin shaft 9 of arm 11 and U type frame 7 of pivoted arm 11 is rotated, the tooth that pull bar 5 that pivoted arm 11 is hinged and support spring 6 make hand lever alligator 4 front ends is meshed with the tooth of tooth plate 1, and contrary by position locking device 15 locking pivoted arms 11 relative U type framves 7, the extreme position that clockwise rotates.
