Abstract

The utility model discloses a plough share with an inclined ladder shape cutting edge, composed of a cutting edge 1, a moldboard wing 3, a support 5, and a bottom board 6. The cutting edge 1 forms an inclined ladder shape, and the moldboard wing 3 forms an arc gradually whose left margin radius is bigger than right margin radius. The support 5 and the bottom board 6 naturally slope to the left. The interaction of the three parts strengthens the side-tumbling force of the clod toward one direction; meanwhile, the scooping depth of a share steel is adjusted through a pin hole 9, which changes the phenomena that the new soil is covered on the old soil when the existing share steel turns over the soil, and the deepness and the shallowness are not easy to adjust, improving the tractor ploughing efficiency. The utility model is suitable for agricultural equipment manufacturers.

Description

A kind of inclined ladder shape edge of a knife ploughshare

Technical field

The utility model relates to a kind of farm implements, and more particularly, the utility model relates to a kind of inclined ladder shape edge of a knife ploughshare.

Background technology

At present, the ploughshare that is linked with during tractor cultivated land, be del mostly, and mouldboard kicker is " U " shape, wing both sides are for waiting arc, during use, be difficult for the grasp except that eating the native depth, it swings to also difficult the grasp earth that is turned over, and angle has deviation slightly, the earth that turns over of ploughing will be swung to the ground ridge that does not climb over, and forms the phenomenon of the old soil of new soil pressure.Take place in order to reduce this phenomenon, tractor driver can only carefully drive, and carefully adjusts the ploughshare angle, causes tractor-ploughing efficient to reduce.Not having preferably at present as yet, ploughshare comes out.

Summary of the invention

This practical purpose is to overcome the deficiencies in the prior art, provides a kind of can the adjusting eat the native depth, the earth that turns over can fixedly swing to the ploughshare of a side.

The purpose of this utility model is achieved by following technical proposals.

The edge of a knife 1 of ploughshare is an inclined ladder shape, and the tip angle of the edge of a knife 1 is 45 °-52 °, and the right border 2 of mouldboard kicker 3 is the camber of radius 19～25cm, and the left border 4 of mouldboard kicker 3 is the camber of radius 28～32cm; About two edge progressively transition form mouldboard kicker 3; Mouldboard kicker 3 lower edge width equate along width with the interior of the edge of a knife 1; The support 5 that has securing member 8 and pin-and-hole 9 is fixed on the base plate 6, and support 5 and base plate 6 be 15 °～20 ° of deflections left naturally, and with nut 7 edge of a knife 1 and mouldboard kicker 3 is anchored on support and the base plate 6, promptly forms inclined ladder shape edge of a knife ploughshare.

The beneficial effects of the utility model are: 1, the edge of a knife is designed to inclined ladder shape, and according to mechanics principle, when eating soil, soil block is easy to a direction rollover; 2, to be designed to an edge radius little for mouldboard kicker, and the big camber of an edge radius is further strengthened the power to a direction rollover; 3, support and base plate have further been strengthened the power to a direction rollover to lopsidedness; 4, three's acting in conjunction, clod just can only be to direction rollovers; 5, prop up and set up pin-and-hole, be convenient to regulate as requested the ploughshare soil depth.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Forge or be cast as the edge of a knife 1 with metal material, the edge of a knife 1 is an inclined ladder shape, and its angle, outer is respectively 50 ° and 127 °.In be respectively 70 ° and 113 ° along two interior angles, the wide 18～19cm in outer, interior along wide 14.5cm, edge of a knife reservation fastener hole.

Forge or be cast as the arc that right border 2 radiuses are roughly 19cm with metal material, left border 3 radiuses are roughly the arc of 29.5cm, about two edge progressively transition form mouldboard kicker 3, the wide 23～25cm of mouldboard kicker 3 upper limbs, the wide 14.5cm of lower edge, and reserve fastener hole.

Make the support 5 that has securing member 8 and pin-and-hole 9 with metal material; Make the base plate 6 that has fastener hole with metal material, and support 5 is fixed on the base plate 6, after fixing, support 5 and base plate 6 should be tilted to the left 15 °-20 ° naturally.

Mouldboard kicker 3 and the edge of a knife 1 be fixed on support 5 and the base plate 6 with nut 7 respectively get final product.

During use, be anchored on the tractor by pin-and-hole 9 with bayonet lock or nut.Eat the native depth, can regulate by pin-and-hole 9.

Claims
