Abstract
The utility model relates to a tillage machine, belonging to agricultural machine class. The tillage machine is characterized in that a parallelogram linkage positioned by a locking pin can make a plough offset to unploughed land side. At the edge and the head of a farmland, the plough can plough out all remaining ploughing band where common plough can not reach. The utility model can also be used for ploughing up the land near fruit trees, fences or wall roots.
Description
The utility model is a kind of tillage machinery of agricultural machinery class.
Be the suspension mouldboard plow of the tractor below 20 kilowatts at present, because its working width is much narrower than the tractor wheelspan, therefore stay area 30-50 centimetre wide always to rand and can't plough (being so-called residual tillaging belt) ploughing, must not be no longer cultivated or by hand digging with ox.Offset plough is exactly the plough that does not stay residual tillaging belt when ploughing.This plough also can be ploughed the area of adjacent fruit tree, hedge or the foot of a wall.All use offset plough on external many small tractors.Biasing mechanism on this plough also has several patterns, but structure is all rather complicated.The horizontal Beam formula board-like as two arcs that Italy produces, that Belgium and Japan produce, and the parallel four-bar type of locating with leading screw and nut etc.All there are some defectives in these mechanisms, or bothersome effort when handling transposition, and are very inconvenient, or complex structure, and cost is too high, or the amount of bias that can reach is very little, or it is very long etc. to plough body.
The purpose of this utility model provides a kind of compact conformation, easy to operate, simple in structure, low cost of manufacture, and can be applicable to the small-sized suspension offset plough of amount of bias greatly, its principle and structure illustrate with following embodiment:
Fig. 1 is the motor-driven figure of the biasing of this plough
Fig. 2 is the vertical view of this plough
Fig. 3 is the cutaway view at G-G place among Fig. 2
As shown in the figure: the horizontal Beam of the suspension of offset plough (1) is connected (upper connecting rod does not draw) by the trifilar suspension mode with two lower links of tractor.Hang on the horizontal Beam (1) parallelogram lindage ABCD is installed.The A of four-bar mechanism, the hinge joint of B two places are being hung on the horizontal Beam (1), C, D two places and the horizontal Beam of plough (3) hinge joint.Plough horizontal Beam (3) and go up two dowel holes (4) and (5) in addition.Plough when general farming, pin-and-hole (4) be fixed on hang the location support arm (6) on the horizontal Beam (1) the end with stop pin (7) locking, so plow frame (8) and plough body (9), (14) are in the position shown in the heavy line among Fig. 1.This moment, the ploughshare alar part was just in time walked the position of the inboard ditch wall line (11) of tire (10) in ditch dug with a plow at tractor, and reserved a little and prevent the lap (12) of balking.
When ploughing the residual tillaging belt that rand leaves over if desired, then stop pin (7) is extracted and pushed plow frame (8) to uncultivated land one side together with plough body (9).At this moment, parallelogram lindage will be in the position of ABEF.Pin-and-hole (5) then arrives in location support arm (6) end " C " the shape card (13).Lock with stop pin (7) this moment.So plow frame (8) and plough body (9), (14) are in position shown in dotted lines in Figure 1.The plough body (14) that is positioned at the rear portion can all be ploughed the area below the tractor left tire (15).After rand, the edge of a field have been ploughed, stop pin (7) extracted and with plow frame (8) and plough body (9), (14) pushed home (position among Fig. 1 shown in the heavy line), again stop pin (7) is inserted in the locating hole (4), plow frame (8) and the location support arm (6) that is fixed on the hanger bracket are locked again, and then plough recovers the general work state again.The transposition of plough is operated in to be finished by the operator on the tractor after plough rises built on stilts.
Claims (1)
1, a kind of suspension type offset plough is made up of plough body, plow frame, hanger bracket and biasing mechanism.The biasing mechanism that is characterised in that of the present utility model is to have plow frame locking " C " shape card (13) and the stop pin that is easy to extract (7) that alternately cooperate with the last dowel hole (4) of plough crossbeam (3), (5) to be constituted by location support arm (6), its end on parallelogram lindage ABCD and the suspension crossbeam (1).
