Abstract
The utility model discloses an oil-return device of a gear case of a combine harvester. The oil-return device comprises an oil-return barrel, wherein an oil return pipe joint and an air vent pipe joint communicated with the oil-return barrel are both arranged on the end surface of the upper end of the oil-return barrel, the oil return pipe joint is connected with an air-permeable opening on the gear case through the oil return pipe, an air vent pipe is connected onto the air vent pipe joint, the oil outlet pipe joint communicated with the oil-return barrel is arranged on the end surface of the lower end of the oil-return barrel, and the oil outlet pipe joint is connected with an oil inlet of the gear case through an oil outlet pipe. One end of a connecting plate is fixedly connected with the oil-return barrel, and the other end of the connecting plate is fixedly connected with a gear case cover through a hanging and connecting hole. According to the utility model, gear lubricant spouted outward under high temperature and high pressure gas during the running of the gear case can be effectively recycled, components and environment around the gear case are prevented from pollution, meanwhile, the recycled gear lubricant can be replenished to the gear case so as to prevent the gear from abrasion, the service life of the gear is prolonged, and the normal work of the gear case is ensured.
Description
Technical field
The utility model relates to the combine-harvester gear-box, and especially a kind of oil return apparatus of combine-harvester gear-box belongs to agricultural machinery technological field.
Background technique
Longitudinal shaft streaming combine-harvester is provided with gear-box before threshing cylinder, be used for commutation horizontal and vertical driving mechanism, this gear-box is the little seal chamber of volume, when inner gear of the gear box runs up, the inner high temperature and high pressure gas that produces, make foamed gear lubricant outwards spray with high pressure draught ventilation mouth from the gear-box, not only waste gear lubricant, also polluted gear-box component and environment on every side, the backgear of inner gear of the gear box lubricant oil loss simultaneously lacks the wearing and tearing easily of lubricated back, shorten the working life of gear, influenced the gear proper functioning, thereby influenced the normal harvesting of crops.
Summary of the invention
The purpose of this utility model provides a kind of combine-harvester gear-box oil return apparatus simple in structure, this device can reclaim the outer gear lubricant of high-temperature high-pressure air flow ejection gear-box that gearbox high-speed running produces effectively, prevents that gear lacks lubricated and weares and teares.
The utility model is achieved by the following technical programs:
A kind of combine-harvester gear-box oil return apparatus, comprise the oil return bucket, be respectively equipped with oil returning pipe joint, the air permeability cell joint that communicates with the oil return bucket on the end face of described oil return bucket upper end, described oil returning pipe joint is connected with ventilation mouth on the gear-box by return tube, connect the air permeability cell on the air permeability cell joint, described oil return bucket lower end surface is provided with the flowline connection to subsea that communicates with the oil return bucket, and flowline connection to subsea is connected with the gear-box filler opening by oil outlet tube.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid combine-harvester gear-box oil return apparatus, be respectively equipped with the connecting plate that extends to a side on the wherein said oil return bucket upper and lower end end face, described connecting plate one end is fixedlyed connected with oil return bucket upper end or lower end respectively, and the connecting plate the other end is fixedlyed connected with gear box cover by mount hole.
The utility model is simple in structure, easy to process, the gear lubricant that its interior high-temperature high-pressure air flow outwards sprays in the time of can effectively reclaiming the gear-box running, avoided polluting gear-box component and environment on every side, the gear lubricant that reclaims in time can also be added in the gear housing simultaneously, prevent gear wear, prolonged the working life of gear, guarantee the proper functioning of gear, thereby guaranteed the normal harvesting of crops.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiments only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is installed in the structural representation on the gear-box.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises oil return bucket 1, and oil return bucket 1 is the seal case through pressure test.End face middle part, oil return bucket 1 upper end is respectively equipped with the oil returning pipe joint 2 that communicates with oil return bucket 1, air permeability cell joint 3, oil returning pipe joint 2 is connected with ventilation mouth 51 on the gear-box 5 by return tube 4, connect air permeability cell 6 on the air permeability cell joint 3, air permeability cell 6 communicates with atmosphere, oil return bucket 1 lower end surface middle part is provided with the flowline connection to subsea 7 that communicates with oil return bucket 1, flowline connection to subsea 7 is connected with the filler opening 52 of gear-box 5 by oil outlet tube 8, on the oil return bucket 1, be respectively equipped with the L shaped connecting plate 9 that extends to a side on the lower end surface, L shaped connecting plate 9 one ends are welded on oil return bucket 1 upper end or the lower end surface, and the other end is fixed on the gear box cover 53 by mount hole 91 and gear box cover fastening screw trip bolt 531.
As shown in Figure 2, when foamed gear lubricant outwards sprays from the ventilation mouth 51 on the gear-box 5 with high pressure draught, gear lubricant flows in the oil return bucket 1 along direction shown in the arrow by return tube 4, carry out reclaiming gear oil, the gear lubricant that reclaims flows in the gear-box 5 along direction shown in the arrow by the oil outlet tube 8 of oil return bucket 1 lower end again, and the gear of lubricated running moves in circles like this, save gear oil, guaranteed the proper functioning of gear.
In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
