Abstract

The invention is transmitted to the cleaning of products from contamination, which improves the quality and productivity of cleaning. When the working fluid is supplied to the hydraulic cylinder 24 and the washing liquid to the manifold with nozzles mounted on the additional frame 10, the hydraulic cylinder rod reciprocates and through the crank the movement is transmitted to the main frame 5, which oscillates relative to the horizontal axis. At the same time, the additional frame oscillates around the horizontal axis. The pawl 20, which is mounted on the crank, transmits movement to one of the ratchet wheels, and a screw is formed, which forms a screw pair with the ratchet wheels. The screw, after having selected its entire stroke, switches the pawl 20 onto another ratchet wheel with the help of a pusher and begins to rotate in the other direction, and the additional frame connected with the screw begins to move in the opposite direction. Thus, the nozzles, due to the rotation of the main frame, move in the horizontal plane, and due to the rotation of the additional frame - in the vertical one. In this case, for each cycle of rotation of the additional frame there is a multiple number of cycles of rotation of the main frame. 6 Il.

Description

The invention relates to the cleaning of products from contamination.

The aim of the invention is to improve the quality and productivity of cleaning.

FIG. 1 shows a blasting machine, front view; in FIG. 2, the same plan view; Fig, 3 - collector, front view; in fig. A - the same kind of plan; FIG. 5 is a section A-A in FIG. 3; FIG. 6 is a diagram of traces of a jet on a vertical plane.

The installation contains a pass-through chamber 1, inside of which platform 2 is placed, collectors 3 and drive 4, the collector is mounted on the main frame 5 with hubs b mounted for swinging at the base 7 fitted with hubs 8, in the main frame on axles 9, perpendicular axles of the hubs of the main frame, an additional frame 10 is installed on which the nozzle 12 is fixed in the holes 11 with the predetermined angle of the nozzle 12, the additional frame 13 is pivotally connected to the rod 14 by hinge, screw 15 is mounted with the possibility of longitudinal movement , the ratchet wheels 16 and 17 are mounted on. The screw 15 is pivotally connected to the thrust 14 and the pushers 18, the hub 6 of the main frame is rigidly connected to the crank 19, on which the two shoulders the pawl 20 and the spring 21 interacting with it are installed, the crank 19 is connected to the drive 4, made in the form of a hydraulic cylinder 22, a limiting rail 23 and a switch 24 of the working fluid of the hydraulic cylinder.

Restrictive rail 23 is provided with a stop 25,

The installation works as follows

The working fluid is supplied to the hydraulic cylinder 22 and the washing fluid to the manifold 3. The movement of the hydraulic cylinder rod is carried out together with the rail 23, which alternately switches the distributor 24 to feed the working fluid to the piston cavity, with its stops 25, resulting in the rod performs reciprocating motion, which is transformed into an oscillatory motion of the crank 19. Together with the crank, the oscillatory motion in a plane parallel to the axis of the hydraulic cylinder, perform the basic 5 and additional 10 frames with Oply 12, Doggie 20 is in engagement with one of the ratchet wheels 16, which, having received movement from the dog, rotates only in one direction, the rotational movement of the ratchet wheel 16 is converted into translational movement of the screw 15, which the thirteen 14 and lever 13 transforms into pivotal movement of the additional frame. The sub-frame rotates in one direction until the screw 15 selects its longitudinal stroke. As soon as the screw selects its turn, the pawl 20, by interacting with one of the pushers 18, switches to the other ratchet wheel 17, which turns the screw in the other direction, which causes a pivoting movement of the additional frame in the outer direction.

Thus, the nozzle by counting the turn of the main frame makes a movement of the horizontal plane, and due to

rotation of the additional frame - in the vertical; in this case, for each cycle of rotation of the additional frame, there are multiple cycles of rotation of the main frame, which leads to an increase in the quality and productivity of cleaning,
