Abstract

The utility model relates to an eight-share adjustable back mounted plough, which is matched with a tractor and composed of a plough body and a hanger, wherein, the plough body is composed of a plough leg, a plough bowl and a plough shovel; the hanger is composed of an oblique beam, a vertical beam, a transverse beam, a lifting rod, a lifting frame, etc.; the plough bowl is a curved surface, the curvature radius of which is varied sectionally; a wedge-shaped shim with a screw rod is arranged on the oblique beam and can adjust the angle of a ploughshare. The utility model has the advantages of small working resistance, adjustable depth, large working width which reaches 1.8 meters, and high work efficiency.

Description

Mounted plough after eight ploughshares are adjustable

The utility model relates to a kind of farm implements, particularly is applicable to the multiplow adjustable hanging plough that uses with tractor.

The turnplow that China uses at present, great majority plough body heavinesses, operation inconvenience, weakness such as tilth should not be adjusted, and working width is less, balks often, backsets and big moat ditch, also should not control, and tractive force is huge, and efficient is low.

The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of working width bigger, and the depth is adjustable, the little and adjustable back of eight ploughshares high efficiency the mounted plough of resistance.

The purpose of this utility model is to realize like this, it comprises plough body and hanger two parts, plough body comprises plow standard, plough bowl and plough shovel, hanger comprises cant beam, along beam, crossbeam, elevating lever, crane, the plough bowl is the curved surface that a radius of curvature segmentation changes, plough bowl and plough shovel are fixedly mounted on respectively on the cassette column, cassette column top is for dehiscing shape and be provided with 4 through holes, can make the cant beam of dehiscing to hold in the mouth hanger of column top, and the cassette column is fixedly mounted on the cant beam by bolt, the taperliner of some band screw rods is installed on the cant beam, the mesopore that its screw rod penetrates bracing frame screws on behind the adjusting nut again, and the mesopore from another bracing frame passes, one end of cant beam connects with tenon with an end of crossbeam, the other end and Shun Liang are fixedly connected, along beam and crossbeam, auxilliary beam is fixedly connected at an angle of 90, crane is installed on crossbeam, elevating lever one end is hinged on the auxilliary beam, the other end is hingedly mounted on the crane, the suspension ploughshare number is eight ploughshares, the radius of curvature of the curved surface first half of plough bowl is R200, the postmedian radius of curvature is R200 and has a radius of curvature to sport the knuckle (see figure 2) of R300 bottom the C-C cutting line, plough bowl afterbody vertical view radius of curvature is R300, plough bowl root edge and horizontal line angle are 50 °, plough shovel approximate trapezoid, inner face is that radius of curvature is the curved surface of R400, the plough point is that 45 ° of plough shovel tail edges and horizontal line angle are 105 ° with the horizontal line angle, plough sword and horizontal line angle are 20 °, and the angle between cant beam and the crossbeam is 55 °.

Advantage of the present utility model: 1, tillage resistance is little, because plough meander face and plough shovel belong to best fit, can reduce tillage resistance effectively; 2, cultivating quality is good, and tilth is adjustable, and the hack performance is good, does not have the phenomenon of balking, backset; 3, high efficiency, economical and practical, because the utility model working width is bigger, the farming dead angle can reach bottom line, the back land readjustment of in addition turning over, dry land, paddy-field-working all can save and repeat the operation procedure of turning over, thereby save human and material resources.

Fig. 2 is plough bowl structure schematic diagram;

Fig. 3 is plough shovel structural representation;

Fig. 4 is plough hanger structural representation.

Provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing:

Plough of the present utility model bowl 8 is made by the quality steel plate of 5 millimeters thick, and hanging beam is made of hollow square steel, during use, hanger can be installed in supporting use on the hydraulic pressure rear linkage of 75 or 65 horsepowers of tractors.When the farming soil property is soft, can 8 ploughs be installed on cant beam 1 at most, working width can reach 1.8 meters, adjusts can extend working width to 2 meter of ploughshare angle; When hardening ground or wasteland, can reduce to seven ploughshare operations as farming.When needs are adjusted the ploughshare angle, can unclamp bolt 6 earlier, turn adjusting nut 12 makes taperliner 10 extend plow standard 7 tops to dehisce among the slit with cant beam 1 then, or therefrom withdraw from, horizontal plane angular adjustment ± 10 ° of ploughshare can be made, bolt 6 location can be screwed after mixing up angle, when needs are adjusted tilth, can select suitable hole to penetrate by the pin taking-up of lifter one end elevating lever 3, tilling depth is regulated between 15～30 centimetres as required.
