Description
Technical field
The utility model relates to a kind of combine grain lifter, and particularly a kind of grain lifter of half-feed combine harvester, belongs to field of agricultural machinery.
Background technology
At present, half-feed combine harvester generally adopts chain reversal means formula grain lifter, mainly comprises power transmission shaft, holds up standing grain arm, hold up upper sprocket wheel, lower sprocket are installed in standing grain arm, upper sprocket wheel, lower sprocket connect by driving chain, be equipped with and hold up standing grain to refer on driving chain, and power transmission shaft is by driving shaft transferring power.Chain reversal means formula grain lifter has and well props up the straight effect of comb for the crop of lodging, can solve preferably plant lodging problem, but its deficiency is: owing to holding up standing grain to refer to adopt high-intensity metal to make, when avoiding work and rugged ground come in contact, cause the problems such as damage that fracture, conventionally hold up standing grain to refer to that minimum point exceeds certain distance than ground, this just causes the crop for serious lodging, its group held up abundant not, and it is higher that rate is dialled in leakage, causes the underproduction.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: a kind of combine grain lifter is provided, can automatically adapts to rugged ground, and not fragile, can fully the crop of serious lodging be propped up, leak rate is low.
Combine grain lifter described in the utility model, comprise driving shaft, power transmission shaft, hold up standing grain arm, hold up upper sprocket wheel, lower sprocket are installed in standing grain arm, upper sprocket wheel, lower sprocket connect by driving chain, on driving chain, be equipped with and hold up standing grain to refer to, hold up standing grain arm bottom to be provided with nearside divider, hinged seat, sliding chamber, the slide of holding up standing grain to refer to comprise to be hinged on driving chain and refer to body, sliding chamber is fixed on hinged seat front end, slide one end is arranged in sliding chamber, the other end connects and refers to body, and two symmetrical elastic parts are housed in the sliding chamber between slide and hinged seat.
By sliding chamber and slide are set, slide can slide along sliding in chamber, thereby makes to refer to that body moves with slide, there is elastic function, under normal operating conditions, by the effect of elastic parts, slide is stretched out, refer to that body is in normal position, in the time referring to that body touches ground, under the effect of impact on ground, refer to that body is by the rapid elasticity of compression assembly of slide, simultaneously slide enters in sliding chamber, refers to body retraction, thus avoided finger body because of huge impact impaired.Owing to referring to that body can adapt to more complicated landform, therefore can, by referring to that height reduces, make its minimum point ground proximity more, thereby improve the ability of holding up of dialling to serious laid crop, reduce leak rate.
Described elastic parts comprise be sleeved on before and after elastomer on two round platforms, pocketed springs outside elastomer, elastomer can be the materials such as rubber, by increasing elastomer enhancing elastic force.
Described sliding chamber is provided with chute, slide is provided with the slide block coordinating with chute, and an adjustment screw is arranged on surface, sliding chamber, and adjustment screw end is against on slide block, by the initial pretightning force of adjustment screw adjustable elastic assembly, can regulate the height and position that refers to body according to actual conditions simultaneously.
Described finger body is made up of front finger body, rear finger body; rear finger body is arranged on slide; front finger body refers to that body is inwardly recessed relatively afterwards; the external side of front finger is equipped with the fingerstall flushing with rear finger surface; before protecting by fingerstall, refer to body; avoid front finger body to cross quick-wearing, fingerstall can be changed after using a period of time at any time.
Described front finger body is provided with card convex, and corresponding fingerstall is provided with projection, avoids fingerstall landing by card convex, easy for installation.
When work, by driving shaft, power transmission shaft, upper sprocket wheel is rotated, upper sprocket wheel drives driving chain and holds up standing grain to refer to rotate, and nearside divider divides crop to center-aisle, while holding up standing grain to refer to go to bottom, stretches out the crop of lodging is propped up and sends into cutting channel.In the time that ground occurs compared with macrorelief, hold up standing grain to refer to that front finger body strikes ground, under the effect of impact, front finger body retraction, avoids fractureing, and when crossing behind uneven ground, front finger body stretches out, and proceeds normal operation.
Compared with prior art, the beneficial effect the utlity model has is:
Combine grain lifter is by arranging sliding chamber and slide, make to refer to that body moves with slide, there is elastic function, adapt to more complicated ground surface or terrain, therefore can will refer to that height reduces, make its minimum point ground proximity more, thereby improve the ability of holding up of dialling to serious laid crop, reduce leak rate; Before fingerstall protection is set, refer to body, avoid front finger body to cross quick-wearing, increase the service life.
