The tillage depth is limited by the depth limiting pressing wheel and the leveling mechanism. The depth limitation is accurate, and the earth surface is smooth after the soil preparation, without wheel mark.
Description
Affiliated technical field
The utility model relates to a kind of facility that are used for carrying out after the ploughing tillage operation, be a kind of combined soil preparing machine tool-carrier specifically, on this tool-carrier, install various whole ground parts, can constitute the combined soil preparing machine of multiple duty, this class combined soil preparing machine is particularly suitable for carrying out the tillage operation that prepare in the seedbed.
Background technology
At present, known combined soil preparing machine is parts such as disk harrow group, spike-tooth harrow group, level land device, hack roller to be installed combine on frame, and one-stop operation can be finished and loosen the soil, hack, smooth and suppress four procedures, is that seeding operation is prepared good kind bed.This class type has 1ZL-4.2 combined soil preparing machine, 1LZ-5.4 combined soil preparing machine, RAU-combined soil preparing machine etc.On the agricultural according to the difference of soil types, soil moisture content and time of site preparation, depth of soil preparation there is different requirements, the adjustment of above-mentioned combined soil preparing machine working depth is achieved in that driving land wheel by hydraulic system rotates (lifting), change the terrain clearance of frame, thereby reach the purpose of adjusting and controlling the workpiece tilth.The mode that tilth is adjusted in this lifting by land wheel has following defective: 1, owing to the difference of soil hardness, the sagging degree of depth of land wheel is also different, causes degree of depth control inaccurate.2, produce the twice rut behind the whole ground, make kind of a bed out-of-flatness, the quality at rut place is hard simultaneously, has caused very big difficulty for follow-up seeding operation and growing of seed.
Summary of the invention
The purpose of this utility model provides a kind of combined soil preparing machine tool-carrier, on tool-carrier, install different workpieces such as disk harrow group, spike-tooth harrow group, level land device, hack roller, packer and can constitute dissimilar combined soil preparing machines, this class combined soil preparing machine tilth precise control does not produce rut behind the whole ground.
The purpose of this utility model is achieved in that and hitch frame, levelling gear, travelling wheel assembly is installed on frame in turn and limits dark press wheel, limits dark press wheel to be installed in the rear portion of frame.Travelling wheel is not in contact with the ground during combined soil preparing machine work, and hitch frame is connected with the draw-gear of tractor, and complete machine weight is born by tractor and the dark press wheel of limit, by changing and limiting the height of the dark press wheel of limit apart from frame, reaches the purpose of control tilth.Limit dark press wheel to have the effect of control tilth, hack and suppression.
Levelling gear is linked in sequence and is formed by bidirectional screw, little, support, pull bar, and bidirectional screw is connected with hitch frame, and pull bar is connected with the travelling wheel general name.Frame was horizontal when levelling gear can make combined soil preparing machine in working order with travel position, thereby made the tilth unanimity of workpiece before and after combined soil preparing machine when work, can improve the road clearance during transportation.
On the dark press wheel bearing of limit, be processed with several adjustment holes.The height of dark press wheel and frame can be adjusted and be limited to backing pin by inserting in the different holes, thereby reach the purpose of control tilth.
The beneficial effects of the utility model are: grading behind the whole ground does not produce rut, the depth of soil preparation precise control.
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is the end view of first embodiment concrete structure of the utility model.
Fig. 2 is the end view of second embodiment concrete structure of the utility model.
Fig. 3 is at the end view that a kind of combined soil preparing machine that forms after the disk harrow group is installed on the combined soil preparing machine tool-carrier shown in Figure 1.
Fig. 4 is the end view of the another kind of combined soil preparing machine that forms after pilot nail tooth harrow group on the combined soil preparing machine tool-carrier shown in Figure 2.
Among the figure 1, hitch frame, 2, bidirectional screw, 3, support, 4, little, 5, pull bar, 6, frame, 7, hydraulic jack, 8, the travelling wheel assembly, 9, bearing pin, 10, the dark press wheel bearing of limit, 11, backing pin, 12, the dark press wheel connecting plate of limit, 13, limit dark press wheel, 14, disk harrow group, 15, the spike-tooth harrow group.
Embodiment
In Fig. 1, hitch frame (1), levelling gear " be linked in sequence and formed by bidirectional screw (2), little (4), support (3), pull bar (5) ", hydraulic jack (7), travelling wheel assembly (8) and limit dark press wheel (13) are installed on frame (6) in turn, limit dark press wheel (13) to be installed in the rear portion of frame (6), limit dark press wheel bearing (10) to be fixed on the frame (6)
Limit dark press wheel connecting plate (12) to be connected with bearing pin (9) with bearing (10), backing pin (11) is inserted in the adjustment hole of bearing (10), backing pin (11) is positioned at the dark press wheel connecting plate of limit (12) top, the position of limitting dark press wheel (13) to move upward is limited by backing pin (11), dark press wheel of this time limit (13) just determines or influences the tilth of combined soil preparing machine apart from the height H of frame (6), limits dark press wheel (13) but downward free floating; The height H of the dark press wheel of limit be can change by the position of adjusting backing pin (11), thereby the adjustment and the qualification of tilth realized apart from frame.
Levelling gear is linked in sequence and is formed by bidirectional screw (2), little (4), support (3), pull bar (5), and bidirectional screw (2) is connected with hitch frame (1), and pull bar (5) is connected with travelling wheel general name (8).Frame (6) was horizontal when levelling gear can make combined soil preparing machine in working order with travel position, thereby made the tilth unanimity of workpiece before and after combined soil preparing machine when work, can improve the road clearance when transportation.
On the dark press wheel bearing of limit (10), be processed with several adjustment holes.The height H of dark press wheel (13) and frame (6) can be adjusted and be limited to backing pin (11) by inserting in the different holes, thereby reach the purpose of adjusting and controlling tilth.
