Problems solved by technology

[0003] The screening devices of the above-mentioned prior art generally have the following technical problems: First, the movement track of the screen plate is single, or it is of the type of shaking up and down or the type of horizontal swing, resulting in a single relative movement of the material during sieving, and the efficiency of the screening material needs to be improved. ; Second, the structure of the screen plate of the prior art is mostly a planar structure, that is, there are only mesh holes that are conducted up and down, and then cooperate with the reciprocating linear motion of this shaking type or swing type of the prior art, resulting in the When sieving, its feeding point only exists at the bottom of the sieve, the space utilization rate of the sieve is low, and the efficiency of the sieve needs to be improved; third, in addition to the above-mentioned technical problems, the screen plate of the plane structure has Lack of barriers on the side, resulting in material leakage during the screening process
Or directly piled up on the construction site. When construction is required, it is necessary to carry out secondary loading and transportation of sand, which is time-consuming and labor-intensive; if a transfer trolley is used to pick up materials, it will cause the transfer trolley to pick up materials for a long time, which will delay the construction time; If the sieved sand is dumped in the prior art carrying device of the prior art, and then carried out centralized delivery to the transfer trolley through the carrying device, it is necessary to monitor in real time whether the carrying device is fully loaded; The sand is mostly used for concrete mixing, and the proportion range of sand in each square concrete is fixed, and the loading device is used for centralized conveying, and secondary weighing is required
In summary, the screening device in the prior art still needs to be improved in connection between screening and subsequent processes.

Embodiment 1

[0049] like Figure 1-3 As shown, this embodiment discloses a rotary shaking type sand and gravel screening device, including a frame 1, a drive motor 21, a connecting rod 22, a lower pressing piece, a movable block 24, a first connecting rod 25, a second connecting rod 26, Fixed sleeve 27, first reset projectile 28, screen 31, sleeve 32, chassis 33, lifting mechanism. The pressing member in this embodiment is preferably a screw sleeve 23 .

[0050] The fixed end of the driving motor 21 is fixed on the frame 1, the output shaft of the driving motor 21 is connected with the top of the connecting rod 22, and the bottom of the connecting rod 22 extends downward. The sleeve 32 is sleeved on the periphery of the connecting rod 22 and there is a gap between the sleeve 32 and the connecting rod 22 . The threaded sleeve 23, the movable block 24 and the fixed sleeve 27 are limited in the sleeve 32 from top to bottom, wherein the threaded sleeve 23 is threadedly matched with the conne...

Embodiment 2

[0078] like Figure 11 As shown, the difference between this embodiment and the above-mentioned embodiment is that a circle of baffles 901 is surrounded on the outer peripheral side of the mesh screen structure, and a blanking box 902 with an upward opening is provided below the mesh screen structure. Sand particles falling from the gap between the baffle plate 901 and the mesh screen structure and the bottom of the mesh screen structure (ie, the bottom mesh 311 ) can fall into the blanking box 902 . A sand outlet pipe 903 is connected to the lower end or bottom of the blanking box 902 .

[0079] The present invention surrounds a circle of baffle plates 901 on the outer peripheral side of the mesh screen structure. The baffle plate 901 can be specifically connected to the frame 1, and a blanking box 902 with an upward opening is arranged under the mesh screen structure. After the sand particles are thrown out through the side of the mesh screen structure, under the blocking a...

Embodiment 3

[0081] like Figure 12-14 As shown, the difference between this embodiment and the above-mentioned embodiment is that the sand outlet pipe 903 is connected with a centralized feeding device, and the centralized feeding device includes a feeding bin 9041, a movable plate 9042, a support spring 9043, a sliding rod 9044, a second reset The projectile body 9045 and the movable plate 9042 are limited in the lower silo 9041 in a sliding fit up and down, and the side surfaces thereof are in sealing contact with the inner wall of the lower silo 9041 . A support spring 9043 is connected between the bottom of the movable plate 9042 and the inner bottom wall of the lower bin 9041 .

[0082] In some embodiments, the support spring 9043 may be a compression spring, and its upper and lower ends may be connected to or in contact with the bottom of the movable plate 9042 and the inner bottom wall of the lower bin 9041, respectively.

[0083] A discharge port is opened on the side of the unlo...

Abstract

The invention discloses a rotary shaking type sand and gravel screening device. An output shaft of a driving motor is connected with the top of a connecting rod, and the bottom of the connecting rod extends downward; a through groove is provided on the sleeve, and one end of a first connecting rod is connected to the movable rod. The block is hinged, the other end of the first connecting rod is hinged with the second connecting rod, one end of the second connecting rod is hinged with the fixing sleeve, and the first reset projectile is assembled so that the other end of the second connecting rod is accommodated in the fixing sleeve; The lower rotating screw sleeve can drive the movable block to slide down so that the other end of the second link sticks out of the through groove; the screen is connected to the sleeve; the chassis is set on the screen and the screen structure can rotate relative to the chassis, and the lifting mechanism is located on the chassis The lower part of the elevator moves synchronously with the connecting rod, and the up and down movement of the lifting mechanism can drive the chassis to reciprocate up and down. The invention has the advantage of high screening efficiency.
