Description

Adjustable quicksand hopper for shot blasting machine Technical Field The utility model belongs to the technical field of quicksand hoppers, and particularly relates to an adjustable quicksand hopper for a shot blasting machine. Background The shot blasting (cleaning) machine is equipment for removing rust and oxide layers, dirt and welding slag on the metal surface, so that the surface of the shot blasting (cleaning) machine is clean and glossy, the roughness of the surface of a workpiece can be increased, the subsequent spraying adhesive force is facilitated, the internal stress of the workpiece can be eliminated, the service life of the workpiece is prolonged, the application of the shot blasting (cleaning) machine is very wide, the most important factor affecting the quality of the shot blasting machine is the shot blasting quantity, and the cleaning effect is better as the shot blasting quantity emitted in unit time is larger. The existing shot blasting machine has two modes of controlling the sand amount, namely a manually-adjusted flashboard, in the process, the added sand amount is difficult to grasp, once too much steel shot is added, the shot blasting motor is overloaded, a control loop is damaged, even the motor is burnt out, the existing shot blasting machine is a pneumatically-adjusted sluice valve, the existing shot blasting machine is not too large, the existing shot blasting machine has the advantages and disadvantages, and the degree of automation is higher, and in the operation process, the shot blasting machine is changed from the operation of knocking the flashboard by a hammer to the button operation. The working current displayed by the manual gate valve or the pneumatic gate valve is not the actual workload, because the reaction force of the impact force from top to bottom of the steel sand (steel shot) is blocked, the steel sand (steel shot) starts to accelerate under the action of the gravity acceleration after flowing into the sand flowing tube, the kinetic energy is naturally and increasingly larger because of the increase of the drop although the mass of the steel shot is not increased, the actual sand throwing amount is the actual workload after the impact force is subtracted, and after the steel shot (steel sand) enters the material guiding tube, the corresponding impact force is generated due to the action of the gravity, the impact force is converted into the kinetic energy to be reacted on the shot wheel in the center of the shot thrower, and the operation of the shot thrower motor is blocked, so that the maximum working efficiency is not achieved. Based on the problems, the application provides the adjustable sand hopper for the shot blasting machine, which can completely eliminate impact reaction force, is matched with the existing controller, automatically adjusts the sand flow after PID advanced operation, keeps the maximum current (actual workload) allowed by the shot blasting motor at any time, and improves the working efficiency by 1 to 3 times. Disclosure of utility model Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides the adjustable sand hopper for the shot blasting machine, which effectively eliminates the impact force of steel shots (steel sand) and prolongs the service life of vulnerable parts such as a material guide pipe, the sand hopper, a shot wheel and the like.
