Abstract
The utility model discloses a transmission case for a miniature potato harvester. The transmission case comprises a case body and has the following main points: a transmission shaft with a fixed gear and a spline shaft with a clutch gear are arranged in the case body; a retainer ring and an engaging and disengaging gear are arranged on the spline shaft; the engaging and disengaging gear is connected with a gearing handle arranged on the transmission case; an output chain wheel is arranged at the outer end of the spline shaft; and an aperture built-in spring and a steel ball are arranged at the part, through which the clutch gear is sleeved on the spline shaft, and used for positioning the clutch gear so as to prevent the clutch gear from sliding on the spline shaft. The utility model has the advantages of simple and compact structure, and convenient and reliable engaging and disengaging operation of the gearing handle, solves the technical problems of the band separation or the gearing failure in the prior art, thereby being an ideal transmission case matched with a miniature potato harvester.
Description
Technical field
The utility model belongs to potato harvest machinery technical field, relates to a kind of small-sized gearbox of potato harvester.
Background technique
At present, domestic potato class mechanized harvest facility mostly with big power tractor, adopt belt interlock mode usually.This Placement during operation, is taken off band or technical problem out of supply easily.
Summary of the invention
The purpose of this utility model is to solve the prior art existence to take off band or technical problem out of supply, provides a kind of small-sized gearbox of potato harvester, to overcome the deficiencies in the prior art.
To achieve these goals, the small-sized gearbox of potato harvester of the utility model, comprise casing, its main points are to be provided with the transmission shaft of band fixed gear and the splined shaft of band clutch gear in the casing, splined shaft is provided with back-up ring and engaging and disengaging gear, engaging and disengaging gear is connected with engage a gear handle on being arranged on gearbox, the outer end of said splined shaft is provided with output sprocket, suit clutch gear position is provided with built-in spring of aperture and steel ball on the splined shaft, be used to locate clutch gear, prevent that clutch gear from sliding on splined shaft.
The utility model is simple and compact for structure, and the clutch engage a gear is lever operated convenient and reliable, has solved prior art and has existed and to take off band or technical problem out of supply, is a kind of desirable and supporting use gearbox of small-sized potato harvester.
Description of drawings
Fig. 1 is the utility model master TV structure schematic representation;
Fig. 2 is that the utility model removes engage a gear handle plan structure generalized section.
Embodiment
According to Fig. 1 and Fig. 2, it comprises casing 1 the utility model, be provided with the transmission shaft 3 of band fixed gear 10 and the splined shaft 8 of band clutch gear 7 in the casing 1, splined shaft 8 is provided with back-up ring 4 and engaging and disengaging gear, engaging and disengaging gear is connected with engage a gear handle 2 on being arranged on gearbox, the outer end of splined shaft 8 is provided with output sprocket 9, and suit clutch gear position is provided with built-in spring 5 of aperture and steel ball 6 on the splined shaft.
The utility model gearbox docks use with the hand tractor gearbox, in the operation process, power passes to clutch gear 7 by fixed gear 10, drives sprocket wheel 9 rotations that are fixed on the splined shaft 8 simultaneously, thereby output power, drive the separating screen operation of potato harvester; Gearbox is provided with engaging and disengaging gear, pulls the position of engage a gear handle 2 to back-up ring 4, and fixed gear 10 and clutch gear 7 are thrown off, and sprocket wheel 9 stops operating, and separating screen stops operation.Be drilled with aperture on the splined shaft 8, built-in spring 5 and steel ball 6 are used to locate clutch gear 7, prevent that clutch gear 7 from sliding on splined shaft 8, overcome potato harvester and phenomenon out of supply occurs when operation.
The utility model form structure is reasonable in design, and the engaging and disengaging gear tiltable is installed, and is convenient to the operation of engage a gear handle 2, and clutch is clear reliable.
