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 mine mechanism technical field, particularly relate to the sieving and grading of the industry solid materials such as ore dressing, building materials, electric power, light industry and chemical industry.
Background technology
Dry classification many employings drum-type grid sieve of coal, reciprocating grid sieve, probability screen and inertia vibrating screen in current colliery, coal washing and thermal power plant.Drum-type grid sieve nest is long-pending large, and screening face is little, and energy consumption is large, and noise is large, product technology is backward, is not inconsistent with existing national industrial policies; Reciprocating grid sieve drives the classification of material by the reciprocating motion of sieve, the speed of service of material is slow, and screening efficiency is low; Inertia vibrating screen makes to be positioned at inclined-plane sieve plate material generation exciting by the exciting force that vibrating motor produces and makes material movement, and the sieve plate simultaneously by being covered with sieve aperture carrys out stock grading; It is low all to there is screening efficiency in above-mentioned screening plant, the shortcomings such as sieve aperture easily blocks, and energy consumption is high, screening noise is large and plant maintenance is difficult, and supporting equipment is adopted damage, can say that the screening of material seriously restricts the development of all departments, all use of the said equipment that used has these puzzled per family.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of adjustable gearbox for screening machine, according to the conveying snap-in force needing adjustment gearbox of material screening registration, can maximize dispersed material simultaneously.
Technical scheme: for solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of adjustable gearbox for screening machine, comprise casing, final drive shaft and some gears, described casing is rectangular box, described final drive shaft is laterally located on casing, some gears adopt the both sides laterally evenly divided and be located at final drive shaft equally, and adjacent two gears are in staggered up and down; Engage each other between the gear of described final drive shaft and adjacent both sides, also engage each other between adjacent gear simultaneously; Between described final drive shaft and adjacent gear, and leave preset pitch between adjacent gear.
The described point of some gears being located at initiative drive shaft both sides are divided into two row by upper bottom, and the gear that described final drive shaft is adjacent is the row being in below, and this row gear is connected with gear major axis.Thus effectively can disperse the material trickled down on screening mechanism, forming drop has the solid space effect caused.
Described final drive shaft and some gears are all located on casing by bearing, and installation portion potential energy corresponding to the bearing of some gears moves up and down.Thus can adjusting gear gap, and then change conveying snap-in force.
Beneficial effect: compared with prior art, the present invention has the following advantages: can provide dispersed power for the crushing and screening mechanism of screening machine, can adjust crushing mechanism gear clearance simultaneously, thus the graduation of instrumentality material screen.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in accompanying drawing 1 ~ 2, the invention provides a kind of adjustable gearbox for screening machine, comprise casing, final drive shaft and some gears, described casing is rectangular box, described final drive shaft is laterally located on casing, some gears adopt the both sides laterally evenly divided and be located at final drive shaft equally, and adjacent two gears are in staggered up and down; Engage each other between the gear of described final drive shaft and adjacent both sides, also engage each other between adjacent gear simultaneously; Between described final drive shaft and adjacent gear, and leave preset pitch between adjacent gear.
The described point of some gears being located at initiative drive shaft both sides are divided into two row by upper bottom, and the gear that described final drive shaft is adjacent is the row being in below, and this row gear is connected with gear major axis.Thus effectively can disperse the material trickled down on screening mechanism, forming drop has the solid space effect caused.
Described final drive shaft and some gears are all located on casing by bearing, and installation portion potential energy corresponding to the bearing of some gears moves up and down.Thus can adjusting gear gap, and then change conveying snap-in force.
