Combined type feeding device used in gravel production

Abstract

The invention discloses a combined type feeding device used in gravel production, and belongs to the technical field of gravel production feeding equipment. According to the technical scheme, the combined type feeding device is characterized by comprising a supporting base, wherein a hopper is arranged above the left side of the supporting base, a feeding frame, a crushing cavity, a feeding barrel and a vibrating screen are sequentially arranged above the supporting base from left to right, a gravel washing machine is arranged below a supporting base, the crushing cavity is used for crushing processing, crushed gravel is completely separated from silt solidified on the gravel, a feeding motor is started, a spiral shaft rotates, the feeding barrel conveniently conveys the crushed gravel to the position above the vibrating screen to be screened, screening holes penetrate through the outer side wall of the feeding barrel, when the gravel is rotationally conveyed in the feeding barrel, the silt is screened out of the feeding barrel, preliminary screening of the gravel is facilitated, a vibration motor is started, screening operation of the gravel is facilitated, the purpose that the gravel and the silt are completely screened is achieved, and therefore, the production and processing quality of the gravel is improved.

Description

technical field [0001] The invention relates to the technical field of sand and gravel production feeding equipment, in particular to a composite feeding device used in sand and gravel production. Background technique [0002] Sand refers to the loose mixture of sand and gravel. In geology, mineral or rock particles with a particle size of 0.074-2mm are called sand, and those with a particle size greater than 2mm are called gravel or breccia. If there are many gravels in the sand It is gravel, called sand and gravel, and some people call sandstone "sandstone" in daily life. [0003] The existing sand and gravel production device has a simple structure. The material is transported to the crusher through the feeder, and the feeder will vibrate when conveying. The purpose is to vibrate and separate the material and sand. However, some sediment solidifies Above the material stone, it is difficult to vibrate and separate the sand from the material stone. The sand that has not be...

[0003] The existing sand and gravel production device has a simple structure. The material is transported to the crusher through the feeder, and the feeder will vibrate when conveying. The purpose is to vibrate and separate the material and sand. However, some sediment solidifies Above the material stone, it is difficult to vibrate and separate the sand from the material stone. The sand that has not been screened completely enters the crusher together with the sand and gravel for processing and crushing, so that the processed sand contains sand and sand, reducing the sand and gravel. production and processing quality
