Abstract
The utility model discloses a crawler travel unit for a minitype grain harvester. The crawler travel unit comprises a travel system and a crawler belt main body which is annularly arranged around the travel system, wherein the crawler belt main body is of an inclined triangular structure, the ratio of three angles of the triangular structure of the crawler belt main body is 10-15:38-43:122-132, and the longest edge of the triangular structure is arranged horizontally and located at the bottommost end. The crawler travel unit is novel in design, travels stably, can be stably travel in both dry land and paddy fields, and is long in service life.
Description
Technical field
The utility model relates to a kind of running gear of miniature harvester, is specifically related to a kind of track unit for rice wheat miniature harvester.
Background technology
Along with social progress and client's development, increasing agricultural equipment is applied in agricultural production, and rice wheat miniature harvester is adapted to the farming in the areas such as the most of mountain regions of China, hills, especially western non-flat-bottomed land.
The running gear of existing miniature harvester is all generally train, certainly, also has plenty of the employing train transmission shearing through the wheat, and the special-purpose crawler type transmission of rice in harvesting paddy field, for adapting to, has more ponding, the situation that bearing capacity is low in paddy field.Because adaptation to the ground, type of drive are different, existing reaper seldom there is take into account the machinery of rice wheat one harvesting.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of track unit for rice wheat miniature harvester, modern design, and smooth running, can take into account in nonirrigated farmland, paddy field and steadily walk, long service life.
To achieve these goals, the technical solution of the utility model: a kind of track unit for rice wheat miniature harvester, it comprises running gear and unifies all crawler belt main bodys around being arranged at this Running System, this crawler belt main body is oblique triangle structure, and three angle ratios of the triangular structure of described crawler belt main body are: 10～15:38～43:122～132, wherein, the longest edge of triangular structure is and is horizontally disposed with and in bottom.
Further, described running gear comprises drive wheel, horizontally disposed front jockey wheel and rear track adjusting wheel, and the first caterpillar wheel between this front jockey wheel and rear track adjusting wheel, the second caterpillar wheel, wherein, described drive wheel is located at the position that midperpendicalar between described front jockey wheel and rear track adjusting wheel is partial to front jockey wheel, and described drive wheel, front jockey wheel, rear track adjusting wheel, the first caterpillar wheel, the second caterpillar wheel rely on the backplate location of these running gear both sides.
Described front jockey wheel is positioned on described backplate by center shaft; Described rear track adjusting wheel is fixed and is connected by center shaft and horizontal slotted hole on described backplate.
Spacing between described front jockey wheel and rear track adjusting wheel is 580mm; Spacing between described the first caterpillar wheel and the second caterpillar wheel is 170mm; Described drive wheel is 220mm from the distance of the horizontal sides of triangular structure.
The beneficial effects of the utility model: this structure design is novel, and smooth running, can take into account in nonirrigated farmland, paddy field and steadily walk, long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structure diagram of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, further describe the utility model.
A kind of as shown in Figure 1 for the track unit of rice wheat miniature harvester, it comprises running gear 1 and around being arranged at this running gear crawler belt main body 2 of 1 one weeks, this crawler belt main body 2 is oblique triangle structure, and wherein, the longest edge of triangular structure is and is horizontally disposed with.
Main improvement in the utility model is the global shape of crawler belt main body 2, its design is to oblique triangle structure, by the applicant, is tested and obtain for a long time, it is than traditional road wheel or the crawler belt of inverted trapezoidal, walk more steady, be more conducive to travelling in paddy field.Three angle ratios for the triangular structure of crawler belt main body 2 are: 10～15:38～43:122～132.Concrete such as, three angles of the triangular structure of crawler belt main body 2 are respectively to 13 °, 40 °, 127 °.
Further, described running gear 1 comprises drive wheel 10, horizontally disposed front jockey wheel 11 and rear track adjusting wheel 12, and the first caterpillar wheel 13, the second caterpillar wheel 14 between this front jockey wheel 11 and rear track adjusting wheel 12, wherein, described drive wheel 10 is located at the position that midperpendicalar between described front jockey wheel 11 and rear track adjusting wheel 12 is partial to front jockey wheel 11, and described drive wheel 10, front jockey wheel 11, rear track adjusting wheel 12, the first caterpillar wheel 13, the second caterpillar wheel 14 rely on backplate 15 location of these running gear 1 both sides.
Described front jockey wheel 11 is positioned on described backplate 15 by center shaft; Described rear track adjusting wheel 12 is fixed and is connected by center shaft and horizontal slotted hole on described backplate 15, by this horizontal slotted hole, the tensioning of 12 pairs of crawler belt main bodys 2 of rear track adjusting wheel is regulated, and also does tension wheel and uses.
Spacing between described front jockey wheel 11 and rear track adjusting wheel 12 is 580mm; Spacing between described the first caterpillar wheel 13 and the second caterpillar wheel 14 is 170mm; Described drive wheel 10 is 220mm from the distance of the horizontal sides of triangular structure.
The technical scheme above the utility model embodiment being provided is described in detail, applied specific case herein the principle of the utility model embodiment and embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, on the specific embodiment and field of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
