Lifting hook type variable-channel shot blasting machine

Abstract

The invention relates to the technical field of shot blasting machine equipment, and discloses a lifting hook type variable-channel shot blasting machine, which comprises a motor, a shell is fixedly connected to the tail of an output shaft of the motor, a feeding port is fixedly connected to the middle of one side of the shell, and a shot blasting opening is formed in the bottom of a shot blastingcavity. Through the arrangement of an installation block and a blocking piece, after a fan-shaped area passes through the shot blasting opening, the blocking piece stretches out under the action of areset spring, a semi-closed environment is formed by the blocking piece and shot blasting blades; and similarly, the fan-shaped area composed of the shot blasting blades that is not rotated to the shot blasting opening forms a semi-closed sector area with the shot blasting blades on the two sides, so that shots in the shot blasting blades do not make contact with the inner wall of the shell any more, impurities in the shots do not enter the space between the shell and the shot blasting blades to cause abrasion and jamming of the shot blasting blades, the shot blasting blades, the shots and the blocking piece move synchronously as a whole, and therefore the problem that the shell and the shot blasting blades are rubbed is solved.

Description

technical field [0001] The invention relates to the technical field of shot blasting machine equipment, in particular to a hook-type variable track shot blasting cleaning machine. Background technique [0002] The hook type shot blasting machine is a kind of machine equipment that uses the high-speed rotating impeller (throwing head) to make the abrasive particles obtain enough kinetic energy to clean the surface of the workpiece, so as to realize the cleaning or treatment of the surface of the workpiece. Rust machine, seen in the production of hydraulic cylinders, is used for sand cleaning, rust removal, descaling and surface strengthening of various castings and forgings of hydraulic cylinders. The shot blasting machine is a machine used to throw projectiles in the hook type shot blasting cleaning machine. The double discs in the shot blasting machine are riveted together to form an impeller body. Eight blades are installed on the impeller body. The shot wheel in the cent...

Problems solved by technology

[0003] However, the traditional shot blasting device still has the following deficiencies in the actual working process: first, when the shot blasting device is working, because the shot blasting blade is always doing rapid rotation in the shell, and the shell is fixed, the When the projectiles flying out of the shot separator enter between the shot blasting blades, if the opening on the shell is just facing the shot blasting blades at this time, the projectiles can be thrown out quickly, but when they are not at the opening at this time, the projectiles will It will be driven by the shot blasting blade, and under the action of centrifugal force, it will stick to the inner wall of the shell, move along the inner wall of the shell with the shot blasting blade, and be thrown out when it rotates to the opening next time, so a large number of projectiles will be thrown out before being thrown out. Under the action of centrifugal force, the inside of the shell rubs violently with the shell, and even some damaged projectiles caused by impacting the workpiece, or impurities such as rust attached to the projectiles will be attached by the projectiles and enter the blaster together. (The projectiles are reused), these impurities are easily stuck between the shot blasting blade and the shell, which not only causes serious wear of the shell and the shot blasting blade, seriously reduces the service life of the shot blaster, and even causes the shot blaster to be stuck It will seriously affect the normal operation of the shot blasting machine and is not conducive to the normal operation of the shot blasting machine.
