Abstract

The utility model discloses a quick-witted gearbox is ploughed a little belongs to the gearbox field. The oil injection device comprises a box body, be equipped with reduction gears in the box body, last input shaft and the output shaft of being equipped with of reduction gears, the top of box is equipped with the oil injection pipeline, oil injection pipeline opening is equipped with sealed lid, the fixed sponge stopper that is equipped with in sealed lid below, still be equipped with the air vent on the sealed lid. The oil injection pipeline of the utility model has the functions of gear oil injection and ventilation, thus reducing the processing difficulty and cost of the gear box; and set up the sponge stopper in sealed lid bottom, the high temperature when having solved the welding leads to the problem that the sponge stopper damaged.

Description

Gear box of micro-cultivator

Technical Field

The utility model belongs to a gearbox, specifically speaking especially relates to a plough quick-witted gearbox a little.

Background

The gearbox oil is an oil product for keeping a gear system lubricated, and can play a role in ensuring the normal work of the gearbox and prolonging the service life of a transmission device. At present machine gearbox is ploughed a little at the during operation, along with the motion of gear and the temperature rise of gearbox oil, gearbox oil can be along with the violent motion of gear and volume expansion, consequently in order to prevent that gearbox internal pressure is too high, can reserve vent pipe on the gearbox to place the sponge stopper that prevents the gear oil splash in vent pipe, owing to receive the opening restriction, inside just need be filled in when vent pipe welds in sponge stopper usually, high temperature during the welding can lead to the sponge stopper to damage. Meanwhile, an oil injection pipeline is arranged on the gearbox and is independent from the vent pipeline, so that the difficulty and the cost of processing the gearbox are increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a machine gearbox is ploughed a little to overcome prior art and plough quick-witted gearbox oil injection pipeline and vent pipe independently separately, increased the degree of difficulty of gear box processing and the defect of cost a little.

The utility model discloses an adopt following technical scheme to realize: the utility model provides a plough quick-witted gearbox a little, includes the box, be equipped with reduction gears in the box, last input shaft and the output shaft of being equipped with of reduction gears, the top of box is equipped with oiling pipeline, oiling pipeline opening is equipped with sealed lid, the fixed sponge stopper that is equipped with in sealed lid below, sealed covering still is equipped with the air vent.

Preferably, the oil injection pipeline is obliquely arranged on the top of the box body.

Preferably, the sealing cover is connected with the oil filling pipeline opening through threads.

Preferably, the side of the box body is provided with an observation window.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the oil injection pipeline of the utility model has the functions of gear oil injection and ventilation, and no ventilation pipeline is needed to be arranged additionally, thus reducing the processing difficulty and cost of the gear box;

(2) the utility model discloses set up the sponge stopper bottom sealed lid, the high temperature when having solved the welding leads to the problem that the sponge stopper damaged.

fig. 2 is a left side view of the present invention;

figure 3 is a front view of the sealing cover of the present invention;

fig. 4 is a plan view of the sealing cover of the present invention.

In the figure: 1. a box body; 2. a sealing cover; 3. an oil injection pipeline; 4. an observation window; 5. an input shaft; 6. an output shaft; 7. a sponge plug; 8. and (4) a vent hole.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figures 1-4, plough quick-witted gearbox a little, including box 1, be equipped with reduction gears in the box 1, last input shaft 5 and the output shaft 6 of being equipped with of reduction gears, the top of box 1 is equipped with notes oil pipe way 3, notes oil pipe way 3 openings is equipped with sealed lid 2, the fixed sponge stopper 7 that is equipped with in sealed lid 2 below, still be equipped with air vent 8 on the sealed lid 2. The gearbox of the mini-tiller works, along with the movement of the gear and the temperature rise of gearbox oil, the gearbox oil violently moves in the gearbox and expands in volume, at the moment, redundant gas in the gearbox is discharged through the sponge plug 7 and the vent holes 8 in the sealing cover 2, the sponge plug 7 acts as buffering violent movement gearbox oil, and the gearbox oil is prevented from being sprayed out through the vent holes 8.

Preferably, the filler pipe 3 is installed obliquely to the top of the tank 1. The obliquely arranged oil filling pipe 3 can further buffer gear oil which moves violently.

Preferably, the sealing cover 2 is in threaded connection with the opening of the oil injection pipeline 3. The threaded connection is firmer, and the sealing cover 2 caused by severe vibration during the operation of the mini-tiller is prevented from falling off. Of course, the sealing cover 2 and the opening of the oil filling pipeline 3 can also adopt an interference fit or other similar fit modes.

Preferably, the side of the box 1 is provided with a viewing window 4. The observation window 4 is used for conveniently observing the oil filling amount of the gearbox, and the situation that the oil filling amount of the gearbox is too much or too little is prevented from occurring.
