Technical scheme: for solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of special-shaped alternating expression 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, and sieve axle assembly comprises frame and is located at several rotating shafts in frame side by side, and the center line of described rotating shaft is parallel to each other; On the external diameter of described rotating shaft, cover has multiple cross sectional shape to be oval thumb wheel component, and described thumb wheel component is provided with multiple gear ring vertically and size reduces successively along the axis of rotating shaft; It is contrary that thumb wheel scantling in described adjacent shafts reduces direction, and engage each other between thumb wheel component, and engagement is also provided with gap between position.
Single motor realizes multiple gear drive by gearbox, and due to gear be engage each other to arrange in Suresh Kumar, thus form solid space, and coordinate can better dispersed material with sieve axle assembly.
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.
The material of described thumb wheel adopts cast iron, plastics or vulcanie to make.
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 ~ 7, a kind of special-shaped alternating expression 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, and sieve axle assembly comprises frame and is located at several rotating shafts in frame side by side, and the center line of described rotating shaft is parallel to each other; On the external diameter of described rotating shaft, cover has multiple cross sectional shape to be oval thumb wheel component, and described thumb wheel component is provided with multiple gear ring vertically and size reduces successively along the axis of rotating shaft; It is contrary that thumb wheel scantling in described adjacent shafts reduces direction, and engage each other between thumb wheel component, and engagement is also provided with gap between position.
Single motor realizes multiple gear drive by gearbox, and due to gear be engage each other to arrange in Suresh Kumar, thus form solid space, and coordinate can better dispersed material with sieve axle assembly.When screen box is that gearbox connects, the gear on gearbox is welded with major and minor axis, and is connected by the rotating shaft that the second shaft coupling is corresponding with sieve axle assembly.Therefore sieve axle assembly shaft and the gear in gearbox to arrange and think that corresponding is upper and lower two arrange or only get and wherein one arrange (such as following).And due to the thumb wheel in rotating shaft be put together by multiple and are interlocked in indenting mode, therefore material both can roll along warp-wise on thumb wheel, also can axially shift, thus better dispersed material.By the corresponding annexation of adjustment rotating shaft with gearbox middle gear major axis, thus can regulate the rotation direction of thumb wheel simultaneously; Or the arrangement of gears intermediate propeller shaft in gearbox, also can change the rotation direction of thumb wheel.
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.
