Abstract
The invention discloses a walking box for a harvester. The walking box is characterized by comprising a conveying shaft, wherein two bevel gears are mounted in the middle of the conveying shaft in a sleeving manner, and an input shaft is connected between the two bevel gears; two bearings are respectively arranged on the outer sides of the two bevel gears and are connected through a sleeve; the two ends of the conveying shaft are respectively connected with two output shafts through two clutches, and springs are connected between the two clutches and the bearings; a left clutch device and a right clutch device are respectively arranged on the clutches, and a left clutch shaft and a right clutch shaft are mounted at the tops of the clutches in a sleeving manner; a reversing shifting fork is arranged between the two bevel gears, and one end of the reversing shifting fork is connected with a reversing shifting fork shaft. The walking box is simple in principle and can walk forwards or backwards through the rotation of the two bevel gears in different directions and the control of the reversing shifting fork, and the left-right turning direction of the walking box can be controlled through the left clutch device and the right clutch device. The walking box has the advantages of being easy and convenient to operate, high in working efficiency, low in manufacture cost and high in practical value.
Description
Technical field
the present invention relates to a kind of walking case for grain header.
Background technology
Grain header refers to the straw cutting down the crops such as paddy and wheat, and is laid in the cereal harvesting machinery in field.Horizontal ceding of Taiwan grain header and two kinds, standing header grain header is had according to the type of the ceding of Taiwan.The most volume of existing grain header is comparatively large, operation inconvenience, very flexible, and manufacturing cost is higher.
Summary of the invention
The object of this invention is to provide a kind of walking case for grain header.
To achieve these goals, by the following technical solutions: a kind of walking case for grain header, is characterized in that: the described walking case for grain header comprises horizontally disposed transmission shaft, is set with bevel gear I and bevel gear II in the middle part of transmission shaft; Between bevel gear I and bevel gear II, tip position vertically connects power shaft; The outside of bevel gear I and bevel gear II is respectively provided with two bearings, passes through sleeve connection between described two bearings; Described transmission shaft two ends are connected two horizontally disposed output shafts respectively by clutch I with clutch II; Clutch I and be all connected with spring between clutch II and bearing; Clutch I and clutch II is also respectively arranged with left and right engaging and disengaging gear, and the top of this left and right engaging and disengaging gear is all set on the clutch shaft of left and right; Also be provided with the fork that falls back between described bevel gear I and bevel gear II, described in fork one end of falling back connect and to fall back fork axle.
Described fork and the fork axle and between having between bevel gear I and bevel gear II of falling back of falling back.
Bearing holder (housing, cover) is provided with outside described bearing.
The principle of the invention is simple, by the rotation of two bevel gear different directions and the control of the fork that falls back, walking case can be realized walk forward or backward, and control its left and right turn by left and right engaging and disengaging gear, it is easy and simple to handle, operating efficiency is high, and cheap for manufacturing cost, has very strong practical value.
Accompanying drawing explanation
Fig. 1 is the front section view figure of the embodiment of the present invention;
Fig. 2 is the cutaway view figure along A-A line in Fig. 1;
Fig. 3 is the perspective view of the embodiment of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figure 1 to Figure 3, a kind of walking case for grain header, comprises horizontally disposed transmission shaft 9, is set with bevel gear I 61 and bevel gear II 62 in the middle part of transmission shaft 9; Between bevel gear I 61 and bevel gear II 62, tip position vertically connects power shaft 7; The outside of bevel gear I 61 and bevel gear II 62 is respectively provided with two bearings 11, is connected between described two bearings 11 by sleeve 12; Described transmission shaft 9 two ends are connected two horizontally disposed output shafts 1 respectively by clutch I 2 with clutch II 10; Clutch I 2 and be all connected with spring 8 between clutch II 10 and bearing 11; Clutch I 2 and clutch II 10 is also respectively arranged with left and right engaging and disengaging gear 3, and the top of this left and right engaging and disengaging gear 3 is all set on left and right clutch shaft 4; Also be provided with the fork 13 that falls back between described bevel gear I 61 and bevel gear II 62, described in fork 13 one end of falling back connect and to fall back fork axle 14.
Described fork 13 and the fork axle 14 and between bevel gear I 61 and bevel gear II 62, there is gap of falling back of falling back.
Bearing holder (housing, cover) 5 is provided with outside described bearing 11.
During work, first make power shaft rotate clockwise, drive two bevel gears to do rightabout motion.Now, operator can come controlled motion direction by manipulating the declutch shift shaft that falls back.
When the declutch shift shaft that falls back is positioned over centre position, the shift fork that falls back also mediates, and does not all contact with bevel gear II with the bevel gear I of both sides, and case of now walking is in neutral gear position, and output shaft does not rotate.
When the declutch shift shaft that falls back is stirred left, the shift fork that falls back then moves right, and combines with bevel gear I, and now, power transmission shaft and fall back shift fork along with bevel gear I synchronous axial system, walking case is in setback state.Now, operator can also carry out Compress Spring by left and right engaging and disengaging gear, thus clutch I is separated, and then can realize left and right turn function when retreating.
In like manner, when the declutch shift shaft that falls back is stirred to the right, the shift fork that falls back is moved to the left, and combines with bevel gear II, and now, walking case is in the state of travelling forward.Now, operator can carry out solenoidoperated cluthes II by left and right engaging and disengaging gear equally thus realize left and right turn function when advancing.
The principle of the invention is simple, by the rotation of two bevel gear different directions and the control of the fork that falls back, walking case can be realized walk forward or backward, and control its left and right turn by left and right engaging and disengaging gear, it is easy and simple to handle, operating efficiency is high, and cheap for manufacturing cost, has very strong practical value.
