Description

A kind of wheat harvester special semi-open type big connecting rod

Technical field

This utility model relates to harvester technical field, particularly a kind of wheat harvester special semi-open type big connecting rod.

Background technology

Combined wheat harvester is the machinery of integration harvesting crops.Disposably complete harvesting, threshing, and by grain collection In to repository, then by conveyer device, grain is being transported in transport vehicle, is disposably completing harvesting.

Big connecting rod is for connection to harvester first and distributes parts of screw feeder and screen box driving arm, and by first point The rotating force joining screw feeder output passes to screen box driving arm by the reciprocating motion of big connecting rod, makes screen box drive arm at screen box Drive under move back and forth, complete to clean the effect of foodstuff grain at work completing screen box.

Traditional big connecting rod is the Internal Spherical Surface bearing block by upper end and the inner plane bearing of the cylinder of interlude and lower end Seat is welded, and the Internal Spherical Surface bearing block of big connecting rod upper end is built with bearing with spherical outside surface, and lower end inner plane bearing block is built with rolling Dynamic bearing, drives the axle of arm to be connected with the axle above eccentric chain-wheel on the first distribution screw feeder and screen box respectively, and harvester is in work When making, big connecting rod receives the next power of the first distribution screw feeder transmission and drives driving arm and screen box ceaselessly to move back and forth, in fortune The power such as the bearing at disorder of internal organs big connecting rod two ends and the contact surface of bearing block are ceaselessly stretched, clash into, inertia and self swing Effect, owing to contact surface and the bearing with spherical outside surface contact surface of Internal Spherical Surface bearing block are affected by machining accuracy and raw material hardness, And the impact that repair demolition is installed, between the Internal Spherical Surface bearing block of big connecting rod upper end and bearing with spherical outside surface contact surface are easy to occur Gap, and the first distribution screw feeder that any small gap all can make to be connected with big connecting rod once occurs and drives arm and screen box Between serious shock and oscillation phenomenon occur so that the first distribution screw feeder ruptures, drive arm and screen box overall because vibrating Excessive and occur rapidly to ftracture comprehensively.

Traditional harvester big connecting rod has and makes improvements it, but after mostly improving still existence and stability poor, Make trouble, technique is loaded down with trivial details, cost is high problem.

So needing to find a kind of mode to solve this problem.

Summary of the invention

For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of little wheat harvest Cutting mill special semi-open type big connecting rod, effectively solves traditional harvester big connecting rod and the most easily occurs between cooperation Gap increases thus causes running part and clean the problem that part large area is damaged.

Its technical scheme solved is that, including the special big connecting rod of harvester, big connecting rod includes cylindrical bar, one end of cylindrical bar Being connected with inner plane bearing block, the other end of cylindrical bar is connected with Internal Spherical Surface bearing block, Internal Spherical Surface bearing block side Centre be provided with opening, opening part is provided with the stay of a pair correspondence, and stay connects, at stay through hinged bolt is fixing It is provided with adjustment pad.

This utility model structure is ingenious, and harvester big connecting rod carries out Position Design again, improves the knot of big connecting rod itself Structure, the design to big connecting rod is kept on improving, it is ensured that the stability of big connecting rod, extends the service life of big connecting rod, reduces harvester Rate of breakdown.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

Being given by Fig. 1 to Fig. 4, this utility model includes the special big connecting rod of harvester, and big connecting rod includes cylindrical bar 1, cylinder One end of bar 1 is connected with inner plane bearing block 2, and the other end of cylindrical bar 1 is connected with Internal Spherical Surface bearing block 3, interior ball The centre of over glaze bearing 3 side is provided with opening 4, is provided with the stay 5 of a pair correspondence at opening 4, and stay 5 is through hinged bolt 6 fixing connections, are provided with adjustment pad 7 at stay 5.

When this utility model uses,

The Internal Spherical Surface bearing block 3 that big connecting rod and the first distribution screw feeder are connected is changed into Semi separation, half opening formula by monoblock type Structure, Semi separation, half opening formula Internal Spherical Surface bearing block 3 are will to offer on the side on an original complete Internal Spherical Surface bearing block One opening 4, has stay 5 at opening 4 and adjusts pad 7, when mounted, first Internal Spherical Surface bearing block 3 being enclosed within spherical axis Hold, afterwards turn over Internal Spherical Surface bearing block 3, Internal Spherical Surface bearing block 3 can be arranged on spherical bearing, finally with bolt 6 warp 5 spherical bearings of stay are fixed, and are provided with adjustment pad 7 at opening 4, in order to adjust Internal Spherical Surface bearing block 3 when maintenance with outer Gap between anchor ring bearing contact surfaces, is allowed to fit clearance, is forever in best fit state, thus change traditional only Have after there is machine parts damage and could find that big connecting rod gap occurs and changes the passive situation of big connecting rod and kit, The probability that broken down when the most both having greatly reduced harvester harvesting, be greatly reduced renewal part maintenance cost and Maintenance time.

This utility model is divided into half opening, Semi separation type Internal Spherical Surface bearing block 33 traditional, Internal Spherical Surface bearing, and Fix stay 5 with bolt 6, considerably increase bearing with spherical outside surface and the pretightning force of Internal Spherical Surface bearing block, make big connecting rod and first During distribution screw feeder work, Internal Spherical Surface bearing block 3 and bearing with spherical outside surface will not occur gap easily, it is ensured that the normal work of harvester Make.

And for some other improve big connecting rods, the most complete split type Internal Spherical Surface bearing block, this utility model is relative For other improve big connecting rod, stability is high, because complete split type Internal Spherical Surface bearing block needs multiple bolts to fix, relies on Bolt fixing easily causing in the external world's loosens and fracture, but if all overall structures, but existence is fixed and is not fastened, nothing Method adjusts the problem in gap, therefore the Internal Spherical Surface bearing block of big connecting rod is designed as Semi separation, the structure of half opening formula, relative to For other, having a lot of advantage, improve stability, manufacturing process is simple a lot, and technological process also becomes simple, reduces Cost.

This utility model structure seems simple, no matter relative to traditional big connecting rod or relative to the Dalian improved Bar, this utility model is all the regeneration product of harvester big connecting rod, occurs because of big connecting rod when i.e. greatly reducing harvester harvesting Gap causes the damage of a series of parts, also makes be greatly improved the service life of big connecting rod, thus has exceeded harvester Service life.

This utility model structure is ingenious, is in operation frequent produced problem for harvester, deeply excavates problem, find Root place, improves the structure of big connecting rod, substantially prolongs the service life of big connecting rod, reduce the use cost of harvester, Greatly reduce the rate of breakdown of harvester simultaneously.
