Abstract

The utility model discloses a crawler belt running device with a height adjustable chassis, which comprises a frame, a driving wheel arranged on the front end of the frame and a tension pulley arranged on the rear end of the frame. The running device is characterized in that one ends of two support bars at the left and right sides of the frame are respectively and movably connected with the frame and the other ends thereof are respectively and fixedly connected with two bearing seats arranged at the left and right sides of the frame. Two support wheels arranged at the left and right sides of the frame are respectively installed on the two bearing seats. One end of a central adjustable support bar is connected with the frame and the other end thereof is connected with a central bearing seat. A central support wheel is arranged on the central bearing seat. One ends of two movable connecting rods arranged at the left and right sides of the frame are respectively and movably connected with the two support bars arranged at the left and right sides of the frame and the other ends thereof are respectively and movably connected with the central bearing seat. The height of the chassis of the crawler belt running device is adjustable and the crawler belt running device is easy in turning with less attached mud. The crawler belt running device can be applied to harvesters, which is especially suitable for small-sized harvesters.

Description

A kind of track unit of adjustable chassis height
Affiliated technical field
The utility model relates to a kind of track unit of adjustable chassis height.
Background technology
At present, the track unit that uses on the reaper, the chassis all can not be regulated, and chassis height immobilizes, and when reaper was turned, crawler belt was scraped and is with a large amount of mud, formed a hollow place in the paddy field, influenced underwater cultivation, and reaper is turned also very difficult.
Summary of the invention
The utility model provides a kind of crawler belt of adjustable chassis height band running gear in order to address the above problem proposition, to its objective is, the track unit adjustable chassis height of this adjustable chassis height is turned easily, and it is few to scrape band mud during turning.
The technical scheme that adopts is: comprise frame 1, be installed in the drive wheel 2 of frame 1 front end, be installed in the tension wheel 3 of frame 1 rear end, it is characterized in that: about two strut bar 4 one ends respectively with frame 1 flexibly connect the other end respectively with about two bearing seats 5 captive joint, about two support wheels 6 be installed in respectively about on two bearing seats 5, middle part adjustable support bar 7 one ends are connected the other end and are connected with middle part bearing seat 5 with frame 1, middle part support wheel 6 is installed on the bearing seat 5 of middle part, about two movable rod 8 one ends respectively with about two strut bars 4 flexibly connect the other ends and flexibly connect with middle part bearing seat 5 respectively.
Compared with prior art, the beneficial effects of the utility model are: the chassis height scalable, turn easily, and it is few to scrape band mud during turning.
Description of drawings
Fig. 1 is the scheme drawing of heightening of the track unit embodiment of adjustable chassis height;
Fig. 2 is the scheme drawing of turning down of the track unit embodiment of adjustable chassis height.
Among the figure: 1, frame, 2, drive wheel, 3, tension wheel, 4, strut bar, 5, bearing seat, 6, support wheel, 7, the middle part adjustable support bar, 8, movable rod.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
At Fig. 1, in shown in 2, drive wheel 2 is installed in the front end of frame 1, tension wheel 3 is installed in the rear end of frame 1, about two strut bar 4 one ends respectively with frame 1 flexibly connect the other end respectively with about two bearing seats 5 captive joint, about two support wheels 6 be installed in respectively about on two bearing seats 5, middle part adjustable support bar 7 one ends are connected the other end and are connected with middle part bearing seat 5 with frame 1, middle part support wheel 6 is installed on the bearing seat 5 of middle part, about two movable rod 8 one ends respectively with about two strut bars 4 flexibly connect the other ends and flexibly connect with middle part bearing seat 5 respectively.
Middle part adjustable support bar 7 is the screw rod that two ends are equipped with screw collar.
Middle part adjustable support bar 7 is the hydraulically extensible bar.
Its working process is: as middle part adjustable support bar 7 is the screw rod that two ends are equipped with screw collar, rotary screw then, screw rod spins out from screw collar, 7 elongations of middle part adjustable support bar, under the pulling of movable rod 8, about two strut bars 4 draw close to the middle part adjustable support bar, the track unit of adjustable chassis height is trapezoidal, raise the position of frame 1.Otherwise the track unit of adjustable chassis height is rectangle, and the position of frame 1 reduces.As middle part adjustable support bar 7 is the hydraulically extensible bar, if the operation hydraulic efficiency gear, but the track unit automatically regulating height of adjustable chassis height.
