Embodiment 1
[0035] Such as figure 1 and figure 2 As shown, the present embodiment provides a fast feeding and screening machine for construction sandstone, including a box body, the box body is cylindrical, the side wall of the upper part of the box body is provided with a feeding port, and the side wall of the lower part of the box body is provided with There is a discharge port, the bottom of the box is equipped with an inclined plate, the lower end of the inclined plate is flush with the lower end of the discharge port, and the outer side of the box is located on the side of the feed port. It includes a first casing, the first casing is cylindrical, and a vertical first rotating shaft is arranged inside the first casing, and a first driving motor for driving the rotation of the first rotating shaft is arranged on the top of the first rotating shaft, and the first driving motor is located at Above the first casing, the first rotating shaft is covered with a first helical blade for lif...
Embodiment 2
[0037] Such as figure 1 and figure 2 As shown, in order to prevent the sieve plate from being blocked by construction sand, this embodiment has been further improved on the basis of embodiment 1. Specifically, a scraper assembly is provided in the box, and the scraper assembly includes a vertical third shaft and a The third driving motor that drives the third rotating shaft to rotate. The third rotating shaft is located in the middle of the box and passes through the middle of the two sieve plates respectively. The third driving motor is located above the box. The third rotating shaft is sleeved with 2 The lower surface of the scraper is evenly distributed with a plurality of protrusions, the protrusions are in the shape of an inverted triangle cone, and the protrusions are integrated with the scraper. The two scrapers are located above the sieve plate and connected to the The distance is less than the particle size of a gravel. Among the construction sandstones falling on ...
Embodiment 3
[0039] Such as figure 1 and figure 2 As shown, this embodiment has been further improved on the basis of embodiment 2. Specifically, a material guide plate is welded on the inner wall of the box, and the end of the material guide plate connected to the inner wall of the box is located at the lower end surface of the circulation inlet. A material guide plate is set on the inner wall of the box. First, it can extend the movement path of the sand and gravel coming out of the circulation inlet, and avoid excessive sand and gravel falling on the sieve plate at the same time to cause accumulation, which affects the screening efficiency; second, the material guide plate The sand and gravel coming out of the circulation inlet can be made to fall near the middle of the sieve plate, and the sand and gravel coming out of the circulation inlet can be prevented from falling directly near the circulation outlet, so that the effect of repeated screening will be deteriorated.
