detailed description

In order to make the above purpose, features and advantages of the utility model more obvious and understandable, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the special shot blasting machine for wheelsets and axle boxes in this embodiment includes a cleaning chamber 1, a screw conveyor 2, a shot blasting device 3, a ball feeding valve 4, a separator 5, and a bucket elevator. machine 6, dust collector 7, air duct 8 and installation room 9.

The quantity of described blasting device 3 is eight, and four blasting devices 3 wherein are installed on the top wall of cleaning room 1, and other four blasting devices 3 are evenly arranged on the side wall of cleaning room 1. Eight blasting devices 3 can clean workpieces to be cleaned from various angles.

One side wall of the cleaning chamber 1 is provided with an electric control material door (not shown) electrically connected to an external electric winch, and the electric winch controls the opening or closing of the electric control material door.

The interior of the cleaning chamber 1 is provided with a self-rotating device (not shown) for carrying workpieces to be cleaned. During the shot blasting cleaning process, the autorotation device can hold and rotate the workpiece to be cleaned, so that the workpiece to be cleaned is fully cleaned.

A maintenance door (not shown) is also provided on the side wall of the cleaning chamber 1, and the components inside the cleaning chamber 1 can be easily maintained by opening the maintenance door.

The bucket elevator 6 and the separator 5 are arranged above the cleaning chamber 1 . The installation chamber 9 is arranged below the cleaning chamber 1 , and the screw conveyor 2 is installed in the installation chamber 9 .

The feed port of the screw conveyor 2 is connected to the cleaning chamber 1, the discharge port of the screw conveyor 2 is connected to the feed port at the lower end of the bucket elevator 6, and the bucket elevator 6 The upper discharge port of the separator 5 is connected with the feed port of the separator 5, the discharge port of the separator 5 is connected with the shot blaster 3, and the discharge port of the separator 5 is connected with the shot blaster 3 is provided with the pill feeding valve 4 that can control whether feeding pills and the speed of feeding pills.
