Abstract
The utility model discloses a hanging device for cultivation and seedling spreading machine with a compound work; up pull rods are hinged with an up pull rod on the tractor; the number of the up pull rods is two and the up pull rods are fixed on the frame though the supporting rods respectively. One end of the up pull rods is arranged with a strip hole, and the up pull rods are hinged with the up pull rods on the tractor through the pins inside the strip holes; and the other ends of the up pull rods are hinged with the frame. The utility model solves the technical problem for the background technique on high cost, inconvenient operation, or poor control stability. The utility model has a simple structure; when the earth fluctuation is large, the rotation seedling spreading machine can float upward and downward freely within a certain scope, and it has no effect on the height of the hydraulic three points lifting.
Description
Technical field
The utility model relates to a kind of combined working machine suspension arrangement by the cultivated seed level degree of land wheel control, concrete multiple operation tilling and seeding machine suspension arrangement.
Background technology
Existing multiple operation tilling and seeding machine is to plough the seed level degree by land wheel profiling control.
A kind of mode that the seed level degree is ploughed in land wheel profiling control is that tractor adopts the semimounted structure with being connected of screw sowing machine, and this semimounted structure needs special hoisting mechanism, and cost is higher, and upper connecting rod must decontrol, and operation is very inconvenient.
The general tractor hydraulic suspension elevator system that adopts is controlled cultivated seed level degree in the practical application.The shortcoming of this structure be plough the ground broadcast not profiling meeting at ordinary times hang mutually with umbrella point.During work, it is quick condition that hydraulic system is in landing, and facility are being supported with ground by front and back profiling gauge wheel and rising and falling, the right trifilar suspension of facility is on tractor, in its degree of freedom that does not vertically have free lifting swing of advancing, that is to say that facility can't profiling, it is extremely unstable to plough the seed level degree.When surface relief was big, the roller of profiling is held concurrently in the back suppression can built on stilts, causes kind of an axle not change, and causes disconnected seedling to be short of seedling.
Summary of the invention
The purpose of this utility model is to provide a kind of multiple operation tilling and seeding machine suspension arrangement, and it has solved and has become operation inconvenience or the extremely unsettled technical problem of cultivated seed level degree in the background technology.
Technical solution of the present utility model is:
A kind of multiple operation tilling and seeding machine suspension arrangement, comprise the upper connecting rod hinged with tractor upper connecting rod 1, its special character is: described upper connecting rod is made of a pair of upper connecting rod 41,42, and described a pair of upper connecting rod 41,42 is fixed on the frame 5 by support bar 61,62 respectively; One end of described a pair of upper connecting rod 41,42 is respectively arranged with cylindrical void 31,32, and described a pair of upper connecting rod 41,42 is hinged with tractor upper connecting rod 1 by the bearing pin 2 that is arranged in the cylindrical void 31,32; The other end of described a pair of upper connecting rod 41,42 is articulated on the frame 5.
The other end of above-mentioned upper connecting rod 41,42 can be respectively directly and frame 5 be hinged.
The other end of above-mentioned upper connecting rod 41,42 also can be hinged by connecting rod 7 and frame 5.
Above-mentioned cylindrical void 31,32 can be vertical bar hole, arc slot or " L " shape cylindrical void etc.
Being connected of above-mentioned upper connecting rod 41 and support bar 61, upper connecting rod 42 were advisable with being connected with hinged of support bar 62; Above-mentioned support bar 61,62 and frame 5 be connected also and be advisable with hinged.
The utlity model has following advantage:
1. profiling change in depth is very little, and changes slowly, thus the good stability of profiling, the reliability height,
2. simple in structure, need not special lifting device, cost is low.
3. when surface relief was big, screw sowing machine can freely fluctuate within the specific limits, and the height of 3 liftings of hydraulic pressure is not had influence.
4. seeding quality height.

Fig. 1 is the side diagrammatic sketch of the utility model embodiment one;
Fig. 2 is the diagrammatic sketch of bowing of the utility model embodiment one;
Fig. 3 is the diagrammatic sketch of bowing of the utility model embodiment two.
Drawing reference numeral explanation: 1-tractor upper connecting rod, 2-bearing pin, 31-cylindrical void, 32-cylindrical void, 41-upper connecting rod, 42-upper connecting rod, 5-frame, 61-support bar, 62-support bar, 7-connecting rod.
Embodiment
Referring to Fig. 1,2, an end of a pair of upper connecting rod 41,42 of the present utility model is hinged by bearing pin 2 and tractor upper connecting rod 1.Bearing pin 2 is arranged in the cylindrical void 31,32 of upper connecting rod 41,42, and bearing pin 2 can slide in cylindrical void 31,32.The other end of upper connecting rod 41,42 is hinged with frame 5 respectively.Upper connecting rod 41,42 passes through support bar 61,62 support fixation respectively on frame 5. Cylindrical void 31,32 on the upper connecting rod 41,42 generally can adopt the vertical bar hole, also can adopt arc slot or " L " shape cylindrical void etc.Being connected of being connected of upper connecting rod 41 and support bar 61, upper connecting rod 42 and support bar 62, support bar 61 and 62 all can adopt hinged with being connected of frame 5.
Referring to Fig. 3, the other end of upper connecting rod 41,42 also can be hinged by connecting rod 7 and frame 5.For example, the other end of upper connecting rod 41,42 can with connecting rod 7 part that is fixed with one, be hinged by connecting rod 7 and frame 5 again.
During work, if surface relief is bigger, profiling gauge wheel in front and back rises and falls with ground, frame 5 drives upper connecting rod 41 by support bar 61 and rises and falls, driving upper connecting rod 42 by support bar 62 rises and falls, because bearing pin 2 bearing pins 2 are at upper connecting rod 41,42 cylindrical void 31, free floating in 32, make screw sowing machine within the specific limits, can freely fluctuate, so, the front and back of upper connecting rod 41, move up and down because cylindrical void 31, the cooperation of bearing pin 2, alleviate, can not involve to tractor upper connecting rod 1, be tractor upper connecting rod 1 can be with the fluctuating of upper connecting rod 41 interlock, therefore do not influence the fixedly suspension of 3 of hydraulic pressure.
