Description

Instruments are known for cleaning the inner surface of the set ;, equipped with a brush that can be rotated at an angle to the axis of the instrument. The described device is also provided with a swivel brush, but differs from the known devices by the control mechanism of the latter. The brush and its conical tapering brush are connected through a crank and a fork with a brush; the latter is under the influence of a handle on a gear rack, and this results in a change in the angle of inclination of the brush during axial movement.

In FIG. 1 is a general view of the instrument; Fig. 2 shows a detail of a gear coupling of a shaft with a brush; FIG. 3 - details of the transmission of rotation to the brush.

The casing / and tube 2 fastened to it enclose the mechanism of the device in its cavity. Motor 5, clutch 4, is connected to the working shaft 5, which bears a tapered bristle 6 at the end. It finally mates with the same bristle 8, which sits on axis 9. The gear 8 is coupled with broomstick 7, which is mounted on axis 10. It is connected to the axis 9 Sliding-Circular Key //, Body Shtickeed

7 passes into the roller 12, carrying at the end the brush 3. The roller 72 passes through the slot in the casing /. The slot allows the roller 12 to move in a vertical direction. On the roller / 2 between the brush 13 and the casing / crank 14 is freely put on, allowing rotation of the roller G-. Krivoschip 4 is connected with fingers 15 to a plug 7b. The IS is connected with the connecting rod 17 with a finger 17, and a passage 19 is mounted on a bracket 19 fastened to tube 2. Finger 20 connects pin 18 to handle 21, which is welded to pinion 22 The handle 21 is hollow.

8e cavity is placed rod 24, ending zybo, entering into one of the depressions of the gear rack 22. The rod 24 is under the influence of the spring 25, which presses the jaws to the gear rack. In the middle part of the stem 24 there is a slot where the dog 2S enters, which can rotate around its axis by means of a pin 27 connected to the button 2 & The appliance is brought to the mold by hand, and the front part is inserted into the cavity of the dip. The device is supported by the hands of a worker by the handle 21 and

a handle 29 located at the rear end of the device. Turning on the electric motor 5, the rotation of the shaft 5, which rotates the brush 75 through the pinions 6, 8, and 7, is reported, thus cleaning the internal cavity of the mold.

If in the course of work you need to change the angle of inclination of the brush relative to the axis of the entire device, then for this the worker presses button 28, forcing the rod 24 to exit with its tooth 23 from the rack of the gear rack 22. Having thus released the handle 21, the worker moves it forward on several teeth of the rail and, lowering the button 28, again fixes the handle 21 in place. When the handle 10 is moved, the rod 18 is deflected (to the left in the drawing), pulling the plug 16 and causing the curvature 14 to turn,

while acting on the roller 12, moves it along with him; thus brush / 5 give the desired angle of inclination. The integral part of the roller 12 gear 7 also deviates, however, it remains engaged with the bristles 8, running around it.

The subject matter of the invention.

A device for cleaning the inner surface of the molds with a brush that rotates at an angle to the axis of the device, characterized in that the brush 13 and its rotating conical scabies 7 are connected with a crankshaft 14 and a fork 16 with a stem 18 under the influence of a adjustable handle 22 on a rack 22. , in order to change the angle of inclination of the brush to the axis of the device during axial movement.
