Abstract
The invention discloses a kind of barrel type screen graders based on helical feed, including drive rod, the drive rod is supported by rack, flight is fixed in the drive rod, the drive rod is located at screen drum cental axial position, and the screen drum and rack are connected, and is fixed with lower hopper in screen drum upper end, the screening hole for having width once to increase from right to left on the screen drum, corresponding position has recyclable device below each screening hole；Retarder is connected in the right end of the drive rod, the retarder is connected to motor.Device is by screw conveyor in conjunction with barrel type screen grader, and energy is positive, inversely sorts back and forth, and sieving capacity is high, and effect is good, and sorting makes to consume less, and cost is low, and dimensional structure is compact, and blanking is convenient.
Description
Technical field
The present invention relates to barrel type screen grader, in particular to a kind of barrel type screen grader based on helical feed.
Background technique
Screw conveyor is a kind of using motor drive spiral revolution, elapses material to realize the machinery of conveying purpose.It
Can horizontal, inclination or vertical transport, have that structure is simple, cross-sectional area is small, good airproof performance, easy to operate, maintenance are easy, are convenient for
The advantages that enclosed conveying.
Currently used sorting device has rotary screen formula sorter, vibration sieve type sorter, disc type sorter etc. several,
The sorter of these types of form exist material hole easily blocks, plastics are easily wound, sorting efficiency is low, processing capacity is small, energy consumption compared with
The defects of high.
Summary of the invention
The invention aims to overcome the above problem, a kind of barrel type screen grader based on helical feed is provided.
In order to achieve the above objectives, the method that the present invention uses is：A kind of barrel type screen grader based on helical feed, including pass
Lever, the drive rod are supported by rack, are fixed with flight in the drive rod, the drive rod is located in screen drum
Mandrel position, the screen drum and rack are connected, and are fixed with lower hopper in screen drum upper end, have from right to left on the screen drum
The screening hole that width once increases, corresponding position has recyclable device below each screening hole；In the right end of the drive rod
Retarder is connected, the retarder is connected to motor.
As an improvement of the present invention, the drive rod is connect with rack by bearing, guarantees that drive rod rotation connects
Continuous property.
As an improvement of the present invention, the corresponding recyclable device seamless connection in the screening hole.
As an improvement of the present invention, the retarder is a pair of of bevel gear set at retarder and motor pass through shaft coupling
Connection.
Beneficial effect：
A kind of barrel type screen grader based on helical feed provided by the invention, device is by screw conveyor and barrel type screen grader knot
It closes, lower hopper blanking is transported material in screen drum by screw conveyor, when material is transported to screen drum screening hole upper end
When, when material is less than screening hole size, material is dropped into recyclable device, as screw conveyor constantly pushes away material
Into material will successively be fallen into recyclable device not of uniform size by its size, to complete the screening of material.
Detailed description of the invention
Fig. 1 is schematic structural diagram of the device of the invention；
Fig. 2 is screen drum structural schematic diagram.
Specific embodiment
Below with reference to embodiment and referring to attached drawing, the invention will be further described, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in width figure, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
A kind of barrel type screen grader based on helical feed as shown in Figure 1 to Figure 2, including drive rod 3, the drive rod
3 are supported by rack 1, are fixed with flight 4 in the drive rod 3, and the drive rod 3 is located at 2 cental axial position of screen drum, with
Drive rod transmission, drive flight rotation.The screen drum 2 and rack 1 is connected, and is fixed with lower hopper 5 in 2 upper end of screen drum,
The screening hole 9 for having width once to increase from right to left on the screen drum 2, corresponding position has below each screening hole 9
Recyclable device 8, recyclable device 8 and screening hole 9 are seamlessly connected.Retarder 6, the deceleration are connected in the right end of the drive rod 3
Device 6 is connect with motor 7.Device by screw conveyor in conjunction with barrel type screen grader, lower hopper blanking, by screw conveyor by object
Material is transported in screen drum, and when material is transported to screen drum screening hole upper end, when material is less than screening hole size, material will
It falls into recyclable device, as screw conveyor constantly promotes material, material will successively be fallen into not of uniform size by its size
Recyclable device in, to complete the screening of material.
A kind of barrel type screen grader based on helical feed provided by the invention, energy is positive, inversely sorts back and forth, sieving capacity
Height, effect is good, and sorting keeps consumption few, and cost is low, and dimensional structure is compact, and blanking is convenient.
The above described is only a preferred embodiment of the present invention, being not the limit for making any other form to the present invention
System, and made any modification or equivalent variations according to the technical essence of the invention, still fall within present invention model claimed
It encloses.
