Accompanying drawing explanation
Fig. 1 is the structural representation of impurity screening device in timber disclosed in the utility model.
Detailed description of the invention
Before explaining detailed description of the invention of the present utility model in detail, should be appreciated that the utility model be not necessarily confined in its structure or structure in the following description the illustrational structure of institute or structure in elaboration and/or accompanying drawing and/or example.The utility model can have other embodiment or can implement in every way.
Below in conjunction with accompanying drawing, impurity screening device in timber disclosed in the utility model is described further.
With reference to Fig. 1, be the structural representation of impurity screening device in timber disclosed in the utility model, described screening device comprises feed arrangement, pond and drawing mechanism.Wherein:
Feed arrangement is arranged on the top of one end, pond, described feed arrangement comprises charging baffle plate 1 and cylinder 2, charging baffle plate 1 is fixed on the edge of one end, pond 5 in arc-shaped, cylinder 2 is arranged at the oblique upper of charging baffle plate 1, described cylinder 2 is provided with and rolls nail 21, roll nail 21 to be fixed on cylinder 2 along cylinder 2 radial direction, roll nail 21 and be axially arranged in a linear in a row along cylinder 2, interval is equal between row and row.
Particularly, adjacent between row and row along cylinder 2 radial direction in 45 ° of angles.
Particularly, the center of circle of circular arc that charging baffle plate 1 is formed overlaps with the center of circle of cylinder, and the tilting of one end of charging baffle plate 1 is pack roller state, and the other end is fixed on edge, pond 5 and tangent with the plane in pond 5.
Particularly, roll nail 21 exposed junction close to charging baffle plate 1, make to roll between nail 21 and charging baffle plate 1 and just do not swipe.
Pond 5 is rectangle, its width is equal with cylinder 2 length or slightly larger than cylinder 2 length, make timber 3 floating in pond 5 be unlikely to disorderly and unsystematic, and near the pond 5 of drawing mechanism 6, there is a slope 51, be unlikely to the timber 3 dropped on pond 5 is fallen in water again.
Drawing mechanism is that ramped shaped is arranged on pond 5 other end, its one end is immersed in pond 5, be exposed at above pond 5 outside the other end, described drawing mechanism comprises drag conveyor 6, drag conveyor 6 comprises live-roller 63 and conveyer belt 62, conveyer belt 62 is provided with the scraper plate 61 perpendicular to conveyer belt, moved by the transmission driving conveying belt 62 of live-roller 63, timber 3 scraping delivery in pond 5 is dropped and enter next manufacturing procedure on the slope 51 in pond 5 by the scraper plate 61 on conveyer belt 62 to conveyer belt 62.
Because one end of charging baffle plate 1 tilts, the other end is fixed on edge, pond 5 and tangent with the plane in pond 5, therefore the rotation of cylinder 2 can be driven by the self gravitation of the timber 3 added, thus realize timber 3 and can enter into pond smoothly, or enter speed in pond 5 to control timber 3, the rotating speed of speed limit or accelerator index drum 2 can be passed through, enter in pond with making timber uniform and stable, when ensure that timber enters in pond 5, impulsive force can not be excessive, the water of inside, pond 5 can not be made to produce wave, keep the relatively placidity of the water surface in pond, be unlikely to affect rubber, iron filings, earth isodensity is greater than the contamination precipitation of water.
Timber 3 enters after in pond 5, density due to timber 3 is less than the density of water, therefore the water surface is swum in, and the impurity 4 such as rubber, iron filings, earth are greater than the density of water due to density, therefore the bottom in pond 5 can be deposited in, along with timber in pond 53 gets more and more, the extruding of the timber 3 added after the timber 3 first added can be subject to be picked up by drawing mechanism 6 by the other end of slowly pushing ahead pond 5 and is transported to next manufacturing procedure.
In timber of the present utility model, the feed arrangement of impurity screening device and drawing mechanism all adopt blade structure and do not adopt rubber conveyer belt to carry, and prevent the possibility again occurring rubber grain impurity.
Although describe the utility model in conjunction with specific embodiment of the utility model; but not in order to limit the utility model; therefore, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
