Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described further.Here, for following example are only used
Bright principle of the present utility model, is not limited to scope of the present utility model.
As it is shown in figure 1, a kind of crawler type grain scraper includes that base 2 and two sets are positioned at the crawler belt row at these base about 2 two ends
Walking apparatus 1, crawler unit 1 includes that crawler belt support body 1, crawler unit 1 are connected with base 2 by crawler belt support body 18.This
In the description of section, in figure, the upside of base 2 is set on the left of it, and the downside of base 2 is set on the right side of it.
As in figure 2 it is shown, often set crawler unit 1 include driving wheel 11, crawler belt 12, gear reduction box 13, torr sprocket wheel 14,
Tensioner 15, directive wheel 16, thrust wheel 17 and crawler belt support body 18 and a servomotor, servomotor represents the most in the drawings
Come；The front end of crawler belt support body 1 is provided with driving wheel 11, and rear end connects directive wheel 16, upper end mounting bracket chain by tensioner 15
Wheel 14, thrust wheel 17 is installed in lower end；Crawler belt 12 is around in above-mentioned all driving wheels 11, directive wheel 16, torr sprocket wheel 14 and thrust wheel 17
Excircle also engages connection；The power output shaft of servomotor is arranged in gear reduction box 13, gear reduction box 13
Power output shaft is arranged on driving wheel 11.Crawler belt 12 selects rubber belt track.This section of description to crawler unit 1 is with reference to figure
2, the left side of crawler belt support body 18 is set to front end, the right side of crawler belt support body 18 is set to rear end.
Often overlap the operation principle of crawler unit 1: the power drive crawler belt 12 exported by servomotor is walked.Concrete
For, the power of servomotor output passes to gear reduction box 13, and the power of gear reduction box 13 output passes to driving wheel
11, driving wheel 11 drives crawler belt 12 to rotate, and crawler belt 12 drives thrust wheel 17 and torr sprocket wheel 14, directive wheel 16 turns while rotating
Dynamic, directive wheel 16 is used for the degree of tightness guiding correctly rotating of crawler belt 12, directive wheel 16 and tensioner 15 jointly to adjust crawler belt 12
Degree, torr sprocket wheel 14 is mainly used to hold in the palm the upper part of crawler belt 12, does not ask sprocket wheel 14, crawler belt 12 to clash into.Zhi Chong
Wheel 17 is used for bearing the weight of entirety and advising positive crawler belt 12.
The beneficial effect of the present embodiment: according to the principle Analysis of crawler unit 1, on the one hand from directive wheel volume 16
The crawler belt 12 gone down is laid down on the ground, and is pressed in below the thrust wheel 17 rolled that advances；On the other hand then last weight
The crawler belts 12 that roll across of wheel 17 are come up by driving wheel volume, so go round and begin again, and therefore have good by property, can preferably fit
Answer the work under the conditions of multiple road.More additionally, all include a servomotor owing to often overlapping crawler unit 1, often overlap
Crawler unit 1 can individually be controlled, so that grain scraper radius of turn is less, it is achieved spin or walk in original place, thus
The features such as this structure has good dynamic property, and revolution is flexible；Meanwhile, the noise of rubber belt track is little, and the life-span is long；With ground contact surface
Long-pending big, reduce the pressure that ground is born.
As the further improvement of above-described embodiment, by the common effect of revolving support 3 with pitching connector 5, it is achieved
The rotation at any angle of frame 6.
As it is shown on figure 3, crawler type grain scraper also includes being installed on base 2 upper end and the revolution that is sequentially connected with from bottom to up is propped up
Support 3, supporting structure 4, pitching connector 5 and support 6.
Revolving support 3 includes can be around the inner ring 31 of the mutual rotary motion of its axis and outer ring 32, and supporting structure 4 lower end
Fixing with inner ring 31 and be connected, base 2 upper end is fixing with outer ring 32 to be connected.Supporting structure 4 lower surface with solid cylinder structure,
The diameter of this cylindrical structure is slightly less than the external diameter of inner ring 31, inner ring 31 is uniformly distributed multiple through hole, by bolt interior
Circle 31 and solid cylinder structure are coaxially fixed.There is a hole on base 2, between hole and outer ring 32, carry out interference fit,
The degree of depth in hole is about 1/2nd of the outer ring height of revolving support 3, is arranged in hole outer ring 32, and outer ring 32 is uniformly distributed
Multiple through holes, are fixed by bolt.The structure of revolving support 3 is as shown in Figure 4.Revolving support 3 selects single four point cantact
Ball-type slewing bearing.
Pitching connector 5 includes that two are fixedly connected on support 6 lower end and the public bearing 51, two that is symmetrically arranged is solid
Surely supporting structure 4 upper end female bearing 52 corresponding with male bearing 51 it is connected to and for the male bearing 51 of stranded connection and mother
The pin 53 of seat 52, wherein female bearing 52 is bolted to connection with supporting structure 4, and public bearing 51 and support 6 are solid by bolt
Fixed connecting, support 6 can axially carry out elevating movement relative to described supporting structure 4 around pin 53, thus realize frame 6 relative to
Supporting structure 4 carries out elevating movement.The description of this section is with reference to Fig. 5 to Fig. 6.
Realize the principle rotated at any angle of frame 6: the working method of revolving support 3 is that outer ring 32 is fixed, inner ring
31 rotate, and are rotarily driven the rotation of frame 6 by inner ring 31.Simultaneously by the strand between pin 53 and male bearing 51 and female bearing 52
Close and connect, it is achieved frame 6 is relative to the elevating movement of supporting structure 4, and pitching connector is simple for structure.
The beneficial effect improved further: for the grain heap of differing heights, need the locus of frame to be adjusted.Root
Understand according to the operation principle described in the preceding paragraph content, by the common effect of revolving support 3 with pitching connector 5, it is achieved frame 6
Rotation at any angle, meet demand.Additionally, revolving support 3 selects single four-point contact ball slewing to support, this revolution is propped up
The construction features held: compact conformation, lightweight, steel ball and arc raceway four point cantact, can bear simultaneously axial force, radial force and
Tilting moment.
