Problems solved by technology

[0003] Existing sand and gravel screening machines generally mix crushed stones together. The size of the stones is different, and they need to be processed by manual screening. Some crushers have screens to sort the gravel. However, stones are easy to block the filter and make it unable to work, and there are also potential safety hazards

Abstract

The invention discloses an adjustable gravel crushing and screening machine, and relates to the technical field of building material machinery. The machine comprises a machine body which internally comprises a crushing part and a screening part, wherein the crushing part comprises two crushing rollers which are arranged on the upper portion of the machine body, an obliquely-arranged movable plateis arranged below the crushing rollers, the left end of the movable plate is movably arranged on a movable shaft, and the movable shaft is fixed to the left side of the machine body; the right side ofthe movable plate is connected to an adjusting mechanism which comprises two b transmission rods, wherein ends of the two b transmission rods are rotatably connected to the two ends of the right sideof the movable plate, the other ends of the two b transmission rods are rotatably connected to two threaded sleeves which are arranged on the threaded rods; and the speed of stones falling into a filter screen is adjusted through the inclination of the movable plate, so that the filter screen is prevented from being blocked due to too fast flowing of the stones.

Description

technical field [0001] The invention relates to the technical field of building materials machinery, in particular to an adjustable sandstone crushing and screening machine. Background technique [0002] With the development of the economy and the advancement of urbanization, there are more and more concrete projects nowadays, and in the production process of concrete, sand and gravel are needed, which makes the concrete more stable when used, so that the construction of houses and roads be more stable. As the main raw material of buildings, sand and gravel are in great demand, but the sand and gravel used as building raw materials are generally relatively small. For the whole stone, it needs to be crushed by a sand and gravel crusher to produce stones suitable for construction. [0003] Existing sand and gravel screening machines generally mix crushed stones together. The size of the stones is different, and they need to be processed by manual screening. Some crushers have...
