Abstract
The utility model discloses a traveling device of a combine harvester, which comprises a frame, crawler belts, a driving chain wheel, a tensioning wheel and two groups of load-carrying wheels which are arranged on the frame, wherein the two groups of load-carrying wheels are arranged in tandem and respectively equipped with a crawler belt guide rail, the crawler belts are wound on the driving chain wheel, the load-carrying wheels and the tensioning wheel; upper belt supporting wheels used for supporting the upper side crawler belts are arranged on the frame and are arranged above the largest interval between adjacent load-carrying wheels; with the arranged upper belt supporting wheels, the upper side crawler belts can be supported to avoid sagginng, and the normal traveling of a harvester in hilly ground can be ensured.
Description
Technical field
The utility model relates to a kind of running gear of track combine.
Background technology
The running part of small-sized caterpillar belt formula reaper generally comprises frame and crawler belt, and the place ahead that described frame is positioned at running part is provided with drive sprocket, moves to drive reaper; The rear that frame is positioned at running part is provided with tension wheel, produces loosening in the long-term use process and comes off to prevent crawler belt; Frame front and back between drive sprocket and tension wheel are provided with two groups of load-carryings wheels, and every group of load-carrying wheel cooperates with a crawler belt guide rail respectively, and the crawler belt guide rail is arranged on the below of load-carrying wheel, prevents crawler belt guide rail tugboat.Described crawler belt is wound on drive sprocket, a plurality of load-carrying wheel and the tension wheel.
In use still there is following problem in the running part of existing small-sized caterpillar belt formula reaper:
1, because crawler belt is a rubber, through after the use of certain hour, the crawler belt of running part top can wear out lax sagging, and influence is walking normally, even may cause that crawler belt comes off.
2, because the rice field of certain areas (as intersected countrys such as Chongqing) is very muddy, and the mud pin degree of depth is dark excessively, sticking a large amount of mud on the crawler belt easily, mud can press down the upside crawler belt like this, causes crawler belt sagging, and influence is walking normally.
Summary of the invention
The utility model purpose is: a kind of running gear of combination machine is provided, and the setting of carrier wheel on it can hold up the upside crawler belt, avoid crawler belt sagging, has guaranteed that reaper also can normally walk at intersected country.
The technical solution of the utility model is: a kind of running gear of combination machine, comprise frame, crawler belt, be arranged on drive sprocket, tension wheel and two groups of load-carrying wheels that front and back are provided with on the frame, every group of load-carrying wheel is combined with a crawler belt guide rail respectively, described crawler belt is wound on drive sprocket, a plurality of load-carrying wheel and the tension wheel, described frame is provided with the last carrier wheel that supports the upside crawler belt, and carrier wheel is arranged on the top of interval maximum between the adjacent load-carrying wheel on this.
Less for fear of the gap between frame and the crawler belt, make things convenient for the dismounting of crawler belt, described upward carrier wheel is arranged on the rear portion of interval maximum between the adjacent load-carrying wheel.
Described upward carrier wheel is lower than the bearing height of drive sprocket to crawler belt to the bearing height of crawler belt, and is higher than the bearing height of tension wheel to crawler belt.
The utility model has the advantages that:
The utility model be provided with on the frame from below guiding and support the upside crawler belt on carrier wheel, being provided with of last carrier wheel can avoid crawler belt sagging the picking-up of upside crawler belt, guaranteed that reaper also can normally walk at intersected country.
Since reaper when crossing ridge etc. and have the convex shape field, its center of gravity be interval maximum at load-carrying wheel, therefore consider that its stability in use, the utility model will go up the top that carrier wheel is arranged on interval maximum between the adjacent load-carrying wheel.
3. to be generally the higher rear side in front side lower in the setting of crawler belt, if carrier wheel is arranged on middle position, will cause the gap between frame and the crawler belt less, it is difficult that the dismounting meeting of crawler belt becomes, and the utility model will be gone up carrier wheel and be arranged on position after maximum leans at interval between the adjacent load-carrying wheel, just avoid the problems referred to above.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 frame; 2 crawler belts; 3 drive sprockets; 4 tension wheels; 5 load-carryings wheel; 51 second load-carryings wheel; 52 the 3rd load-carryings wheel; 6 crawler belt guide rails; Carrier wheel on 7.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of running gear of combination machine, comprise frame 1, crawler belt 2, be arranged on the drive sprocket 3 of frame 1 lower front portion, being arranged on the tension wheel 4 of frame lower rear and two groups is arranged on the frame 1 and front and back are arranged in load-carrying wheel 5 between drive sprocket 3 and the tension wheel 4, every group of load-carrying taken turns 5 belows and is combined with a crawler belt guide rail 6 that is fixed on the frame 1 respectively, crawler belt guide rail 6 plays the effect that prevents that crawler belt from coming off, described crawler belt 2 is wound on drive sprocket 3, on a plurality of load-carrying wheels 5 and the tension wheel 4, described frame 1 is provided with the last carrier wheel 7 that supports upside crawler belt 2, the described bearing height of going up 7 pairs of crawler belts 2 of carrier wheel is lower than the bearing height of 3 pairs of crawler belts 2 of drive sprocket, and is higher than the bearing height of 4 pairs of crawler belts 2 of tension wheel.Being provided with of last carrier wheel 7 can hold up upside crawler belt 2, avoid crawler belt 2 sagging, guaranteed that reaper also can normally walk at intersected country.
In order to ensure the stability of reaper when crossing ridge etc. and have the convex shape field, the utility model will be gone up carrier wheel 7 and be arranged between the adjacent load-carrying wheel 5 top of maximum at interval.Further, less for fear of the gap between frame 1 and the crawler belt 2, make things convenient for the dismounting of crawler belt 2, the described carrier wheel 7 of going up is arranged on the rear portion that interval maximum between 5 is taken turns in adjacent load-carrying.In the present embodiment, two groups of load-carrying wheels 5 have two load-carrying wheels 5 separately, be by being provided with four load-carrying wheels 5 behind the forward direction successively on the frame 1, wherein maximum at interval between second load-carrying wheel the 51 and the 3rd load-carrying wheel 52, be maximum at interval, the described carrier wheel 7 of going up is arranged between second load-carrying wheel the 51 and the 3rd load-carrying wheel 52 and the position of close the 3rd load-carrying wheel 52.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
