Problems solved by technology

Due to its uneven particle size, the sand and gravel cannot meet the construction requirements, and a crushing device is needed to crush it. After the existing crushing device crushes the sand and gravel, it is necessary to manually pour the sand and gravel that does not meet the crushing requirements into crushing. Crushing in the device, labor-intensive, low work efficiency

Embodiment 1

[0022] see Figure 1~4 , in an embodiment of the present invention, a sand and gravel crushing device for building construction includes a frame 1 and a crushing assembly 2 installed on the frame 1. The bottom of the crushing assembly 2 is provided with a dovetail slider and a The dovetail chute on the top is slidingly connected, and a feeding hopper 11 is arranged above the crushing assembly 2, and the material is fed into the crushing assembly 2 through the feeding hopper 11; a screening device and a screening device are also provided in the frame 1 The conveying device provided by Unicom, the screening device is located below the crushing assembly 2, and is used to screen out the incompletely broken sand and gravel, and the conveying device is arranged on the side wall of the frame 1, and is used to displace the screening device The unsatisfactory sand and gravel screened out are conveyed into the feed hopper 11, and crushed again by the crushing assembly 2, and the materia...

Embodiment 2

[0029] see figure 1 , in the embodiment of the present invention, a sandstone crushing device for building construction, in order to ensure the screening quality of the second conveyor belt 5, on the basis of embodiment 1, the frame 1 is also provided with a feeding plate 15 and Located below the first conveyor belt 4, it is used to introduce the gravel sieved by the first conveyor belt 4 to the feeding end of the second conveyor belt 5, so that the gravel is fully in contact with the sieve holes on the second conveyor belt 5 and screened, effectively The gravel screened by the first conveyor belt 4 is prevented from directly entering the second screw blade 6 from the discharge end of the second conveyor belt 5 .

[0030] The working principle of the present invention is:

[0031]When working, open the feeding door 12, feed materials into the crushing assembly 2 through the feeding hopper 11, close the feeding door 12; start the crushing motor 25, and the crushing motor 25 dr...

Abstract

The invention discloses a gravel crushing device for building construction. The device comprises a rack and a crushing assembly arranged on the rack, wherein the bottom of the crushing assembly is provided with a dovetail sliding block and is in sliding connection with a dovetail sliding groove formed in the rack, and a feeding hopper is arranged above the crushing assembly; and a screening deviceand a conveying device communicating with the screening device are arranged in the rack, wherein the screening device is located below the crushing assembly, and the conveying device is arranged on the side wall of the rack. According to the device, the feeding hopper with a feeding door is adopted, so that dust and impurities are prevented from falling in, and the dust, generated during gravel crushing, is prevented forming polluting the environment; the crushing assembly with an adjusting assembly is adopted, so that different gravel crushing requirements can be met, and the flexibility ishigh; a first conveying belt and a second conveying belt which are provided with different sieve holes are adopted, and a first spiral blade and a second spiral blade are matched, so that large-particle gravels are screened out, circulating crushing is achieved, the crushing effect is enhanced, and the uniformity of gravel particles is guaranteed.

Description

technical field [0001] The invention relates to a crushing device, in particular to a sandstone crushing device for building construction. Background technique [0002] Sand and gravel, which refers to a loose mixture of sand grains and gravel, is the most common material used in building construction. Due to its uneven particle size, the sand and gravel cannot meet the construction requirements, and a crushing device is needed to crush it. After the existing crushing device crushes the sand and gravel, it is necessary to manually pour the sand and gravel that does not meet the crushing requirements into crushing. Crushing in the device has high labor intensity and low work efficiency. Contents of the invention [0003] The object of the present invention is to provide a sand and gravel crushing device for building construction, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention pro...
