Abstract
The utility model belongs to a shell for ship type machine, which is characterized in that the two sides of the bottom of the shell are respectively provided with a longitudinal rib. The utility model is suitable for the ship type machine to work in paddy fields, tidal flats and marshes, which can not only reduce the spray resistance of the ship body by 20-30% and extend the service life of the shell by 100-200% but also increase the running rectilinearity of the ship type machine.
Description
The utility model is a kind of housing of boat type machine, belongs to the body carrier of boat type machines such as boat-type tractor, boat form rice transplanter slide plate, boat form vehicle.Be applicable to the paddy field, tidal land, marshland work.
Existing boat type machine is characterized in utilizing most of weight of this carrying of shell boat type machine, makes its support at upper soll layer and within reason sinking.Drive the wedge shape driving wheel extruding of boat type machine and shear soil by engine, make boat type machine obtain driving force and tractive force, thereby slide at upper soll layer.Because the effect of body weight, the muddy water layer of upper soll layer are forced out the shell bottom, the shell bottom is directly contacted with soil, so resistance of taxing is big, the hull bottom serious wear.Under existing maintenance condition, its shell all will change once general every year.
The purpose of this utility model provides a kind of novel shell that can prolong shell service life, reduce resistance of taxing.
Characteristics of the present utility model are that shell (1) two bottom sides respectively has a fin longitudinally, and the rear portion of fin is mutually neat with the shell afterbody, and anterior circular arc at an angle closely links to each other with shell and exceeds soil layer.V font, u font can be selected according to the soil texture in the cross section of fin, and rectangle.Optimal selection is a rectangle.
Concrete structure of the present utility model is as shown in drawings:
The upward view of Fig. 1 shell bottom.
The end view of Fig. 2 shell.
The front view of Fig. 3 shell.
(1) is shell among the figure, and (2) are fin, and (3) are the muddy water film, and (4) are upper soll layer, 2 longitudinally fin (2) respectively in shell (1) two bottom sides.Fin (2) afterbody is mutually neat with stern, exceed soil layer (4) on the front portion, like this, when hull is walked forward, can make muddy water be forced to be pressed into hull bottom by the effect of fin (2), and be blocked between two fins, just form the thin muddy water film (3) of one deck between shell bottom and the upper soll layer, thereby can reduce resistance of taxing 20～30%, reduced the hull bottom wearing and tearing, prolong shell 100-200% in service life, simultaneously, two fins (2) are pressed into upper soll layer (4), make soil form groove, carry certain lateral deflection power, thereby improved the linearity of travelling of hull.Fin on the shell (1) can be cast with shell and form, and perhaps adds and burn-ons, or get on screw is affixed.Thick 3～the 5mm of fin, wide 15～20mm, its manufacturing materials can be metal such as steel, iron etc., also can be plastics, fiberglass, hard fibre and hard man-made fibre material.
Claims (3)
1, a kind ofly is used to carry boat-type tractor, the boat form rice transplanter waits the shell of boat type machine, it is characterized in that the shell two bottom sides respectively has a fin longitudinally, the rear portion of fin is mutually neat with the shell afterbody, and anterior circular arc at an angle closely links to each other with shell and exceeds soil layer.
2, shell according to claim 1, the cross section that it is characterized in that fin can be V font, u font and rectangle, and optimal selection is a rectangle.
3, the manufacturing materials of its fin of shell according to claim 1 and 2 is metal such as steel, iron, also can be plastics, fiberglass, hard fibre and hard man-made fibre material, fin can be cast with hull and form, and also can add to burn-on or get on screw is affixed.
