Abstract
The invention discloses an adjustable gearbox for a screening machine. The adjustable gearbox comprises a box body, a main driving shaft and a plurality of gears, wherein the box body is a rectangular box body, and the main driving shaft is transversely arranged on the box body; the plurality of gears are transversely and uniformly arranged on the two sides of the main driving shaft, and every two adjacent gears are arranged in an up-and-down staggered manner; the main driving shaft is meshed with the gears on the two adjacent sides, and meanwhile the adjacent gears are meshed with each other; preset clearances are reserved between the main driving shaft and the adjacent gears and between the adjacent gears. The adjustable gearbox for the screening machine is capable of providing uniform dispersion forces for a smashing and screening mechanism of the screening machine, meanwhile adjusting the clearances of gears of a smashing mechanism and thus regulating the material screening grade.
Description
Technical field
The invention belongs to the row such as mine mechanism technical field, more particularly, to ore dressing, building materials, electric power, light industry and chemical industry
The sieving and grading of industry solid material.
Background technology
Adopting drum-type grid sieve, reciprocating lattice the dry classification of coal in colliery, coal washing and thermal power plant at present more
Son sieve, probability screen and inertia vibrating screen.Drum-type grid sieve volume is big, and screening surface is little, and energy consumption is big, and noise is big, product technology falls
Afterwards, it is not inconsistent with existing national industrial policies；Reciprocating grid sieve drives the classification of material, material by the reciprocating motion of sieve
The speed of service slow, screening efficiency is low；Inertia vibrating screen is made positioned at inclined-plane sieve plate material by the exciting force that vibrating motor produces
Producing exciting makes material movement, simultaneously by being covered with the sieve plate of sieve aperture come stock grading；All there is screening effect in above-mentioned screening plant
Rate is low, and sieve aperture easily blocks, and high energy consumption, screening noise are big and the shortcomings of plant maintenance is difficult, and to supporting equipment using damaging
Bad it may be said that the serious development restricting all departments of the screening of material, all used the said equipment with there being these to puzzle per family.
Content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of adjustable for screening machine
Section gearbox, can maximize dispersed material according to the conveying snap-in force needing regulation gearbox of material screening registration simultaneously.
Technical scheme：For solving above-mentioned technical problem, the present invention employs the following technical solutions：A kind of for screening machine can
Adjust gearbox, including casing, final drive shaft and some gears, described casing is rectangular box, and described final drive shaft is horizontal
It is located on casing, some gears are equally using the laterally homogeneous both sides set up separately in final drive shaft, and two neighboring gear is in up and down
Staggered；Engage each other between described final drive shaft and the gear of adjacent both sides, also engage each other between adjacent gear simultaneously；
Between described final drive shaft and adjacent gear, and between adjacent gear, leave preset pitch.
The described some gears setting up separately in initiative drive shaft both sides by bottom be divided into two row, described final drive shaft is adjacent
Gear is the row being below, and this row gear is connected with gear major axis.Trickle down on screening mechanism so as to effective dispersion
Material, forming drop has the solid space effect of cause.
Described final drive shaft and some gears are all located on casing by bearing, and the corresponding installation of bearing of some gears
Position can move up and down.Such that it is able to adjust gear clearance, and then change conveying snap-in force.
Beneficial effect：Compared with prior art, the present invention has advantages below：Can carry for the crushing and screening mechanism of screening machine
For dispersed power, crushing mechanism gear clearance can be adjusted simultaneously, thus the graduation of instrumentality material screen.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention is further described.
As shown in accompanying drawing 1～2, the present invention provides a kind of adjustable gearbox for screening machine, including casing, main transmission
Axle and some gears, described casing is rectangular box, and described final drive shaft is laterally located on casing, and some gears equally adopt
The laterally homogeneous both sides set up separately in final drive shaft, and two neighboring gear is in staggered up and down；Described final drive shaft with adjacent
Engage each other between the gear of both sides, also engage each other between adjacent gear simultaneously；Between described final drive shaft and adjacent gear,
And between adjacent gear, leave preset pitch.
The described some gears setting up separately in initiative drive shaft both sides by bottom be divided into two row, described final drive shaft is adjacent
Gear is the row being below, and this row gear is connected with gear major axis.Trickle down on screening mechanism so as to effective dispersion
Material, forming drop has the solid space effect of cause.
Described final drive shaft and some gears are all located on casing by bearing, and the corresponding installation of bearing of some gears
Position can move up and down.Such that it is able to adjust gear clearance, and then change conveying snap-in force.
