Description
Technical field
The utility model relates to a kind of conveyer of combine, and especially a kind of harvested material conveyer of combine belongs to agricultural machinery technological field.
Background technology
Combine is a kind of harvesting that can once finish crops, threshing, separation cane, remove operation such as assorted excess, gathers in shelling from the field and finishes the harvesting machinery that directly obtains grain.The harvested material conveyer of existing combine is installed in the ceding of Taiwan, during the rotation of screw feeder cylinder, by several expansion teeth assemblies harvested material side-delivery rake outside the ceding of Taiwan is advanced, by screw propulsion blade harvested material is pushed the sheller unit threshing then with the rotation of screw feeder cylinder.Every group of several expansion teeths are respectively along the flexible rake material of the circumference of screw feeder cylinder, the back shaft of expansion teeth assembly departs from screw feeder centre of the drum, relative position with the ceding of Taiwan is relative remains unchanged for it, and then keeps relative motion between the screw feeder cylinder of rotation, makes expansion teeth can stretch out rake and gets harvested material; When expansion teeth rotated to position near the ceding of Taiwan along with the screw feeder cylinder, expansion teeth can be withdrawn, and prevents from harrow is gone into.Expansion teeth one end and the back shaft of expansion teeth assembly are hinged, fixedly connected with an end of two radius bars respectively in the back shaft two ends, and two radius bar other ends are fixedlyed connected with the driving shaft, the regulating shaft that drive screw feeder cylinder two ends respectively.Because expansion teeth is impacted in rake material process, causes the taper bolt of radius bar and driving shaft fixed connection place to be cut off easily, influences the operating efficiency of combine, and whole equipment mechanism complexity, welding, assembling, maintenance difficult.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of harvested material conveyer that assembles the combine of easy to maintenance, designs simplification, long service life.
The utility model is achieved by the following technical programs:
A kind of combine harvested material conveyer, comprise the ceding of Taiwan, rake material assembly, the screw feeder cylinder, described rake material assembly comprises regulating shaft, several expansion teeth groups, back shaft, first radius bar, second radius bar, driving shaft, described array expansion teeth is uniform along the screw feeder roll circumference, described back shaft, first radius bar, second radius bar is arranged in the screw feeder cylinder, described back shaft two ends respectively with first radius bar, one end, second radius bar, one end is fixedly connected, axially spaced-apart between several expansion teeth groups, be staggered, the expansion teeth group comprises in a row spaced several expansion teeths, described expansion teeth one end is hinged by mount pad and back shaft, and the expansion teeth other end stretches out from the circumference of screw feeder cylinder; Described driving shaft one end is hinged by bearing I I and second radius bar, one end, the driving shaft other end with pass the screw feeder cylinder after screw feeder cylinder one end is fixedlyed connected, be bearing in the ceding of Taiwan by bearing I, fixedly connected with drive in driving shaft other end termination.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid combine harvested material conveyer, be provided with several width of cloth dishes at interval along axis in the wherein said screw feeder cylinder, regulating shaft one end is bearing on the width of cloth dish I by bearing I II, and driving shaft one end bearing is on width of cloth dish II, and the driving shaft other end is fixedlyed connected with the width of cloth dish III of screw feeder cylinder one end.Described bearing I I is a deep groove ball bearing.
Owing to adopted above technical scheme, the utlity model has following beneficial effect:
Screw feeder cylinder of the present utility model is by the transmission rotation of drive, the bolster of expansion teeth assembly is with respect to ceding of Taiwan invariant position, and be in the eccentric position of screw feeder roll circumference, when the screw feeder cylinder rotated, the expansion teeth in a row of interlaced arrangement realized that the rake material moves stretch respectively around screw feeder centre of the drum when rotate at the bolster center.Expansion teeth has been subjected to the side knock effect of harvested material in the process of rake material, impulsive force is delivered on the back shaft, though fixedly connected with first radius bar, second radius bar, one end respectively in the back shaft two ends, but because the driving shaft and the second radius bar other end are hinged by bearing I I, and the first radius bar other end is bearing on the screw feeder cylinder by the bearing I II on the regulating shaft, thereby can effectively not prolong service life of the present utility model because of being fixedly connected and cause the damage of parts.Because adopting articulated manner is not the original mode that is rigidly connected, thereby structure is more reasonable, assembles and keep in repair convenient.
Bearing I I of the present utility model adopts deep groove ball bearing, and the former quantity of screw feeder cylinder reduces 1, has reduced manufacturing cost,
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises the ceding of Taiwan 1, rake material assembly 2, screw feeder cylinder 3, rake material assembly 2 comprises regulating shaft 21, several expansion teeth groups 23, back shaft 24, first radius bar 22, second radius bar 25, driving shaft 28, support the screw feeder cylinder 3 outer screw propulsion blades 34 that are provided with in the screw feeder cylinder 3 at interval by several width of cloth dishes.4 expansion teeth groups 23 of present embodiment are axially staggered uniform along screw feeder cylinder 3 circumference, back shaft 24, first radius bar 22, second radius bar 25 are arranged in the screw feeder cylinder 3, fixedly connected with first radius bar, 22 1 ends, second radius bar, 25 1 ends respectively in back shaft 24 two ends.Axially spaced-apart between the expansion teeth group 23, be staggered, every group of expansion teeth group 23 comprises 3 expansion teeths 231,23 every groups of 3 expansion teeths of 4 expansion teeth groups 231 are in a row staggered to be spaced, expansion teeth 231 1 ends are fixedlyed connected with mount pad 232 by split pin, mount pad 232 is hinged with back shaft 24, and expansion teeth 231 other ends stretch out from the circumference of screw feeder cylinder 3.Driving shaft 28 1 ends are hinged by the bearing I I27 and second radius bar, 25 other ends, driving shaft 28 other ends are welded on the flange 281, flange 281 with pass screw feeder cylinder 3 after the width of cloth dish III33 of screw feeder cylinder 3 one ends is fixedlyed connected, be bearing in the ceding of Taiwan 1 by bearing I 11, fixedly connected with drive 210 in driving shaft 28 other end terminations, driving shaft 28 1 end bearings are on width of cloth dish II32, first radius bar, 22 1 ends are fixedlyed connected with regulating shaft 21 1 ends, and regulating shaft 21 is bearing on the width of cloth dish I31 by bearing I II29.
