The crawler shot blasting machine is a high-strength wear-resistant rubber crawler or manganese steel crawler for loading workpieces. It uses a high-speed rotating impeller to throw projectiles onto the workpiece in the chamber to achieve the purpose of cleaning. It is suitable for sand removal, rust removal, scale removal and surface strengthening of small castings, forgings, stamping parts, gears, springs, etc. It is especially suitable for cleaning and strengthening parts that are not afraid of collisions. This machine integrates domestic and foreign technology, is a kind of cleaning equipment with good cleaning effect, compact structure, low noise, and is used for surface derusting or shot blasting in large and medium batch production. It has the following characteristics: 1. It adopts cantilever centrifugal shot blasting machine, which has the characteristics of long service life and simple structure; 2. Three ejection speeds of 75 m/s, 80 m/s and 85 m/s are used. 3. The pulley adopts the internationally advanced quick-change structure, which is beneficial to improve production efficiency and reduce labor intensity. 4. The BE type separator is adopted, which has good separation effect and high productivity, and has a positive effect on improving the life of the blade; 5. Adopt bag filter, the dust emission concentration is lower than the national standard, which improves the working environment of workers; 6. This model adds some special mechanisms such as manual pill gate and discharge gate. 7. The crawler shot blasting machine of this model can be used as a stand-alone machine or by wiring.
