Abstract

The utility model relates to a cultivation and ridging machine which belongs to the technical field of the agricultural cultivation machine and solves the problem that the ball type connection hanging frame has poor transverse stability. The utility model is characterized in that the length of an upper pull rod is regulated through a screw bar and a screw nut, the transverse balance of the upper pull rod can also be regulated, a lower pull frame adopts the fixed connection with complete machine and a traction plate, and the transverse stability of the complete machine during the operation is increased. The utility model has the advantages of simple structure and low cost. The utility model can be used in the cultivation operation as well as the ridging operation before the spring sowing.

Description

Three-row tiller

The utility model relates to a kind of intertillage and ridging facility, belongs to agriculture harvesting and tillage machine tool technical field.

At present, known cultivator can only be intertilled can not ridging, and reason is that the hanger bracket lateral stability that connects of ball formula is poor, and the teeter amount is big when making complete machine in working order, the whole ground ridging operation when being unfavorable for sowing in spring.Towing plate is a foundry goods in addition, gains in weight cost up, waste material.

The purpose of this utility model provides a kind of simple in structure and lightweight ploughing equipment that can intertill and can ridging.

The purpose of this utility model is to realize like this, by towing plate (1) and tractor with small four wheels rear haulage base plate Joint, lower tie frame (8) is connected as one with towing plate (1) and crossbeam (9), land wheel portion dress (11) and plough body portion dress (12) are fixed on the crossbeam (9), make laterally freely-movable of crossbeam (9).Lower tie frame is set a roof beam in place (13) by a left side and front beam (14) welding, and setting a roof beam in place (16) and rear cross beam (17) welding in the right side, combines under the effect of securing member (15); And about set a roof beam in place two ends place be welded with stiffener (18), set a roof beam in place in a left side and right support (19) is made by angle steel.Upper connecting rod (7) connects by axle (3) with support arm (6) and fixed support (2), movable sleeve (20) and movable sleeve (27) can vertically rotate on axle (3), and movable sleeve (27) can relative lateral rotation under the effect of semi-ring (26) and rotating shaft (25), reach the effect that the complete machine lateral balance is adjusted, the main body of upper connecting rod (7) is pull bar (24), screw mandrel (21) moves in screw (23) and adjusts the length of upper connecting rod (7), is locked by nut (22) after length mixes up.Towing plate (1) is made by angle steel, promptly replaces foundry goods with steel part, and very big variation has also taken place planform.

Owing to adopted technique scheme, the problem of lateral stability difference when having solved the cultivator operation reaches this machine can to intertill and two job requirements that can ridging, improved the transaction capabilities of facility, save material, reduced cost, improved operating efficiency.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of lower tie frame (8).

Fig. 3 is the set a roof beam in place structural representation of (16) of the right side.

Fig. 4 is the structural representation of upper connecting rod (7).

As shown in Figure 1 towing plate (1) and tractor rear haulage base plate Joint, form quadric chain with fixed support (2) by spool (3) by last tie-bar (7) and support arm (6) and lower tie frame (8), pulley (5) and steel wire rope (4) are formed elevating mechanism moves up and down four connecting rods drive crossbeam (9) and plow stick seat (10) and land wheel portion dress (11) and plough body portion dress (12), realize the complete machine action of rising and falling, under the effect of upper connecting rod (7) and lower tie frame (8), lateral stability strengthens when making the complete machine operation, and can intertill again can ridging.

Claims (3)

1, the triplex row harvesting and tillage machine, by towing plate (1) and fixed support (2) welding, support arm (6) is welded on the crossbeam (9), plow stick seat (10) plough body portion dress (12) and land wheel portion dress (11) are fixed on the crossbeam (9), pulley (5) and steel wire rope (4) link with support arm (6) and fixed support (2), it is characterized in that upper connecting rod (7) links by axle (3) and fixed support (2) and support arm (6), and the length of upper connecting rod (7) can be passed through rotating rod (24) adjustment, movable sleeve (27) can pass through the relative teeter of effect of semi-ring (26) in axle (3), lower tie frame (8) links by axle (3) and towing plate (1) and crossbeam (9), and lower tie frame (8) is set a roof beam in place (13) by a left side and front beam (14) welding, set a roof beam in place (16) and rear cross beam (17) welding in the right side, under the effect of securing member (15), combine, about frame crossbeam two ends places be welded with stiffener (18).

2, triplex row harvesting and tillage machine according to claim 1, the length conciliation that it is characterized in that upper connecting rod (7) is to relatively rotate realization by screw (23) on leading screw (21), and the teeter of movable sleeve (27) is that the rotation in pull bar (24) lining realizes by turning cylinder (25).

3, triplex row harvesting and tillage machine according to claim 1 is characterized in that set a roof beam in place (13) in a left side and right support (19) is to make of angle steel, and the angle of inclination is 8 °-12 °.
