Problems solved by technology

The middle plow share 40 of the present invention is fixed between the frame-shaped main beam 7, and the tractor driver only needs to set the middle plow share in the ridge when traversing the ground, and the left plow share 30 and the right plow share 50 can be used according to the The size of the distance between the ridges can be automatically tracked and adjusted, which solves the problem of the uneven distance between the ridges and the damage to the seedlings in the prior art.

specific Embodiment approach 1

[0005] Specific embodiment one: (referring to Fig. 1, Fig. 2) present embodiment is made up of frame-shaped girder 7, two ground wheels 13, traction connecting frame 14, two U-shaped clamps 16, left plow share 30, middle plow share 40, right plow share The plowshare 50 is composed of; the traction connecting frame 14 is fixed on the middle part of the front side of the frame-shaped main beam 7, and the two ground wheels 13 are respectively fixed on the lower part of the rear side of the frame-shaped main beam 7, and the middle plowshare 40 is fixed by two U-shaped clips 16. Fixed on the lower side of the middle of the frame-shaped main beam 7, the left plowshare 30 and the right plowshare 50 are respectively arranged on the left and right sides of the lower part of the frame-shaped main beam 7, and the left plowshare 30 and the right plowshare 50 slide with the frame-shaped main beam 7 respectively connect. The left plow share 30 and the right plow share 50 are respectively co...

specific Embodiment approach 2

[0006] Specific embodiment two: (referring to Fig. 2) the difference between this embodiment and specific embodiment one is that there are through holes 18 on the facades of the beam ferrules 8 on the left plowshare 30 and the right plowshare 50 respectively, A nut 9 is fixed in the through hole 18, and a bolt 10 is arranged in the nut 9, and the front end of the bolt 10 is connected with the rear side of the frame-shaped main beam 7. Other compositions and connections are the same as in the first embodiment. The effect of the increased nuts 9 and bolts 10 is that when the ridges are turned up in spring or autumn, in order to keep the same distance between the two ridges, the frame-shaped main beam 7 must be tightly supported by the bolts 10, so that The left plowshare 30 and the right plowshare 50 cannot slide left and right along the frame-shaped girder 7 . Only in this way can the distance between the new ridges be guaranteed, and the effect of the three plows will be comp...

specific Embodiment approach 3

[0007] Specific embodiment three: (see Fig. 3) the difference between this embodiment and specific embodiment one is that the pulley 1, the pulley bracket 2 and the slide rail 15 are replaced by the front beam ferrule 17, and the front beam ferrule 17 is fixed on On the front end upper side of the front flat beam 12 of the belt along the beam 11, the front end of the front beam ferrule 17 matches with the frame-shaped main beam 7. Other compositions and connections are the same as in the first embodiment. This embodiment is particularly suitable for field operations where the soil is relatively hard. Such as alkaline compacted soil and so on.

Abstract

An adjustable three-share plough features that its central share is fixed to a frame-shape main beam by two U-shaped fasteners and its left and right share can slide on said main beam, so the distance between them can be adjusted according to the spacing between ridges for protecting crops.

Description

Technical field: [0001] The invention relates to the improvement of the three-share plow structure in agricultural tillage machinery. Background technique: [0002] The distance of its three plowshares of the existing three-share plow is fixed. When raising the ridge, the distance between the two ridges plowed by the three-share plow is standard, but when the two ridges are raised and lowered, it is different from the corresponding Large or small ridges are likely to appear when the distance between the adjacent ridges is poorly grasped. In the shoveling season, due to the existence of large or small ridges, the existing three-share plow cannot adjust the ridge distance, and sometimes the entire rice seedlings in the large or small ridges can be shoveled off, resulting in a lack of seedlings. The loss is almost irreparable. Moreover, there are so many agricultural machinery manufacturers now, and some farmers are also constantly reforming agricultural machinery and tools. ...
