Walking case is mainly used on mini-size tillage machine, the oil sealing of the axis hole tapping of existing walking case is directly exposed, therefore, when case was walked in use in the past, grass and rubbish can be involved in casing from the gap of oil sealing and rotating shaft, cause user in use to need the work of often carrying out removing grass and rubbish, cause unnecessary work to user.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of
The utility model solves the technical scheme that its technical problem adopts: the novel anti-sticking grass walking case of a kind of mini-size tillage machine, comprise casing, described casing offers axis hole, rotating shaft is provided with in described axis hole, the rotating shaft of described axis hole opening part is socketed with sheath, described sheath is fixedly connected with the casing of described axis hole opening part, the rotating shaft of described sheath external end is socketed with axle sleeve, there is the first running clearance between described end face of shaft bush and sheath end face, the first bolt passes axle sleeve and screws in rotating shaft and is fixed in rotating shaft by described axle sleeve.
Further, described axle sleeve forms one section of outer bulge loop on the end face of sheath side, described outer bulge loop stretches in the trepanning of sheath, the second running clearance is there is, the first described running clearance and the rectangular structure of the second running clearance between the outer wall of described outer bulge loop and the trepanning inwall of described sheath.
Further, the fixed connection structure between described sheath and casing is:
The casing of described axis hole opening part offers several second bolts hole, the second bolt screws in the second bolt hole of casing through after sheath, is connected on casing by described sheath.
Further, be provided with oil sealing in described axis hole, described oil-sealing sleeve is connected in rotating shaft.
Further, the first described running clearance is 0.2 ~ 2mm.
Further, the second described running clearance is 0.2 ~ 2mm mm.
The beneficial effects of the utility model are: by the improvement to original walking box body axis hole place, set up sheath and axle sleeve, rely on the running clearance of at right angles structure between the two, thus avoid walking case operationally, outside grass and rubbish are directly involved in casing, improve the service efficiency of the mini-size tillage machine with this kind of walking case, also extend the service life of walking case simultaneously.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figures 1 to 4, the novel anti-sticking grass walking case of a kind of mini-size tillage machine, comprise casing 1, casing 1 offers axis hole, be provided with rotating shaft 2 in axis hole, the cross section of rotating shaft 2 is hexagonal structure, is provided with oil sealing 6 in axis hole, and oil sealing 6 is socketed in rotating shaft 2.The rotating shaft 2 of axis hole opening part is socketed with sheath 3, sheath 3 is fixedly connected with the casing 1 of axis hole opening part, the rotating shaft 2 of sheath 3 outer end is socketed with axle sleeve 4, there is the first running clearance between axle sleeve 4 end face and sheath 3 end face, the first bolt 5 passes axle sleeve 4 and screws in rotating shaft 2 and is fixed in rotating shaft 2 by axle sleeve 4.
Axle sleeve 4 forms one section of outer bulge loop 41 on the end face of sheath 3 side, and outer bulge loop 41 stretches in the trepanning of sheath 3, there is the second running clearance between the outer wall of outer bulge loop 41 and the trepanning inwall of sheath 3, the first running clearance and the rectangular structure of the second running clearance.The running clearance of right-angle structure can better prevent grass and rubbish to be involved in casing 1.
Fixed connection structure between sheath 3 and casing 1 is: the casing 1 of axis hole opening part offers several the second bolt hole 11, second bolts and screw in the second bolt hole 11 of casing 1 through after sheath 3, be connected on casing 1 by sheath 3.The quantity of the second bolt hole 11 and the second bolt preferably 3.
First running clearance is 0.2 ~ 2mm.Second running clearance is 0.2 ~ 2mm.
Walking case of the present utility model, by the improvement to original walking box body 1 axis hole place, set up sheath 3 and axle sleeve 4, rely on the running clearance of at right angles structure between the two, thus avoid walking case operationally, outside grass and rubbish are directly involved in casing 1, improve the service efficiency of the mini-size tillage machine with this kind of walking case, also extend the service life of walking case simultaneously.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
