Efficient sand producing machine for constructional engineering

Abstract

The invention discloses an efficient sand producing machine for constructional engineering. The machine comprises a sand producing machine main body. A crushing chamber is formed in the sand producingmachine main body, a second bearing pedestal is installed on the inner wall of one side of the crushing chamber, a second bearing and a third bearing are installed inside the second bearing pedestal,the second bearing is located on one side of the third bearing, a connection rod is connected between the second bearing and the third bearing, a side door is fixedly connected with the outer wall ofone side of the sand producing machine main body through a bolt, a first bearing pedestal is installed in the middle position of the side door, and a first bearing is installed inside the first bearing pedestal. Since the first bearing pedestal, the second bearing, the first bearing, a limiting groove and a limiting pin are arranged, during overhaul and replacement, a locking bolt on the first bearing pedestal in the middle position of the side door is unscrewed tightly, a spring rebounds after the locking bolt is unscrewed, a push block is pushed into an installation groove, meanwhile, a lock rod is taken out of the limiting pin through a push rod, and axial unlocking of a main shaft is achieved.

Description

technical field [0001] The invention belongs to the technical field of sand making machines, and in particular relates to a high-efficiency sand making machine for construction engineering. Background technique [0002] The sand making machine is suitable for crushing soft, medium hard and extremely hard ore materials with a hardness not higher than 320Pa. The sand making machine is widely used in large, smelting, building materials, roads, railways, water conservancy and chemical industries. Sand making machines include horizontal hammer type, vertical shaft hammer type, vertical shaft impact type and roller type. [0003] However, the existing sand making machines in the market are prone to wear and tear on the main shaft and blades in the process of crushing materials, and the main shaft and blades need to be repaired and replaced regularly, but the repair and replacement methods of the existing sand making machines are complicated, and the sand making machine In the cru...
