Problems solved by technology

However, the anisotropic separation of materials with different particle sizes in this technical solution is based on the fact that the materials are always in a flowing state during the sieving process, which will greatly shorten the sieving time of the materials, resulting in insufficient sieving and rework Serious technical problems, and this kind of drum sieving device has a large volume, and it is mostly used for screening large-scale materials such as ore, sand, and garbage, and is not suitable for small-batch materials.

Embodiment 1

[0047] Such as figure 1 , 2 As shown, the present embodiment discloses a screening device, which includes a hand-held rod 11, a screen 21, a turning plate 22, a side baffle 3, a lifting mechanism 4, a first guide plate 51, a second guide plate 52, and a feeding channel , Stretch mechanism 7.

[0048] The side baffle 3 includes two side plates 31 and a sliding plate 32 arranged oppositely, and the two side plates 31 and the sliding plate 32 can form a structure with three sides closed, one side open, and up and down conduction. Such as Figure 3a , 3bAs shown, the turning plate 22 is rotatably engaged with the opening side of the side baffle 3 , and the first elastic member 818 is assembled so that the turning plate 22 covers the opening side of the side baffle 3 . The stretching movement of the stretching mechanism 7 is used to drive the sliding plate to slide towards the position direction of the turning plate 22 . One side of the screen 21 abuts against the inner wall o...

Embodiment 2

[0061]As shown in FIGS. 4-9 , the difference between this embodiment and the above-mentioned embodiments is that it provides a specific way that preferably the handle bar 11 , the sliding plate 32 , the turning plate 22 , and the second guide plate 52 cooperate with each other.

[0062] It includes a first connecting rod 811 , a second connecting rod 812 , a lift rack 813 , a first gear 814 , a rotating disc 815 , a third connecting rod 816 and a second gear 817 . The lower end of the turnover plate 22 is rotatably engaged with the lower end of the opening side of the side baffle 3. Specifically, the lower end of the turnover plate 22 can be rotatably connected with the lower end of the opening side of the side baffle 3 through a hinge or as Figure 3b As shown, the lower end of the turnover plate 22 is connected to the first shaft 819, and the two ends of the first shaft 819 are respectively in rotation with the two sides of the lower end of the opening side (the inner walls o...

Embodiment 3

[0073] As shown in Figure 4, the difference between this embodiment and the above-mentioned embodiments is that: a connecting plate 91 and a second elastic member 92 are arranged on the side baffle plate 3, and the second elastic member 92 is arranged between the sliding plate 32 and the connecting plate 91. between. The second elastic member 92 is preferably a spring such as a compression spring, and its two ends can be connected or hooked to the sliding plate 32 and the connecting plate 91 respectively.

[0074] In the present invention, the connecting plate 91 and the second elastic member 92 are arranged on the side baffle plate 3. When the sliding plate 32 is pushing towards the position of the turnover plate 22, the second elastic member 92 is deformed. When the 74 is connected with the sliding plate 32, when the sliding plate 32 is facing away from the turning plate 22 position direction to perform reset movement, the second elastic member 92 is used to reset the elasti...

Abstract

The invention discloses a screening device. The lifting mechanism is used to drive the screen to move up and down in a space-limiting cavity surrounded by a turning plate and a side baffle; the first material falling from the mesh of the screen can move along the first The guidance of the first guide plate and the second guide plate moves downward until it falls from the top of the end of the second guide plate; rotating the hand-held lever can drive the sliding plate to move towards the position of the flip plate, the flip plate turns downward, and the second guide plate back Move to the first guide plate until the feeding hole is exposed synchronously; cause the second material in the screen to move synchronously to the position of the turning plate until part of the second material can fall from the side opening between the turning plate and the side baffle. Into the feeding through hole, another part of the second material can fall from top to bottom from the inclined turning plate. The invention also discloses a concrete aggregate grading separation and feeding device. The invention has the advantages that the materials are fully sieved, and the unloading of the residual materials in the sieve net and the sieved materials at different designated positions can be conveniently realized.

Description

technical field [0001] The invention relates to the technical field of construction engineering material processing, in particular to a sieving device and a concrete aggregate grading separation and feeding device. Background technique [0002] Material sieving is to separate the first material with smaller particle size from the second material with larger particle size by putting the material to be sieved into the screen and filtering it through the mesh of the brush. [0003] The objects of material sieving can be automotive interior parts particles, automotive sealing strip granules, sand and gravel, fertilizer raw materials, crops, paint, construction waste, coal mines, etc. Therefore, material sieving technology is widely used in chemical industry, construction, machinery, etc. , agriculture and other industries. [0004] The material sieving device in the prior art is such as a powder sieving device disclosed in patent application 201320537002.5. The power mechanism ...
