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 thumb wheel screening machine, can be more effective in material screening, avoids solid accumulation to block, maintenance convenient disassembly.
Technical scheme: for solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of thumb wheel screening machine, comprise motor, reduction box, the first shaft coupling, gearbox, the second shaft coupling, axle bed and screen box, described motor, reduction box, the first shaft coupling, gearbox, the second shaft coupling are connected successively with screen box, wherein
Described gearbox comprises casing, final drive shaft and some gears, described casing is rectangular box, described final drive shaft is laterally located on casing, and 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;
Described screen box comprises screen box casing and is located at the sieve axle assembly in casing, sieve axle assembly comprises frame and is located at several rotating shafts in frame side by side, on the external diameter of described rotating shaft, cover has cross sectional shape to be oval thumb wheel, this thumb wheel is provided with multiple gear ring vertically, and the thumb wheel in adjacent shafts engages each other, engagement is provided with gap between position.
Describedly be enclosed within thumb wheel in rotating shaft and be made up of multiple thumb wheel section.
The material of described thumb wheel adopts cast iron, plastics or vulcanie to make.
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.Therefore drive axis of rotation by major axis that gear connects, due to upper the next two row modes, and combine rotating shaft side by side, thus can solid space be formed, make material can through repeatedly sieving and grading.
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 the clearance distance adjustment on energy countershaft between thumb wheel, thus be suitable for the screening of all size material.
Beneficial effect: compared with prior art, the present invention has the following advantages: single motor is transmitted by gearbox thus provides power to some thumb wheels; Can provide axially and the upset of warp-wise for the crushing and screening mechanism of screening machine, improve the degree of scatter of material, crushing mechanism gear clearance can be adjusted simultaneously, thus the graduation of instrumentality material screen; In addition can for convenience detach and replacing.
