Description

one

This invention relates to devices intended for the processing of food products during cooking. Grinding devices are known in which the grinding of a product is carried out in a closed bowl with quick-rotating knives. For service safety, most devices have interlocks that disable the blade drive when the cover is removed. Interlocks are performed by both electrical and mechanical I.

The closest in technical essence is a device comprising a frame with a cone mounted on it, a lid fixing on the body in inclined clips, a thicket, a drive shaft with a coupling and knives (2.

The disadvantage of this device is the complexity of the locking device, in addition, it does not preclude the removal of the cover during operation.

The purpose of the invention is to increase the operational capabilities of the device.

This goal is achieved in that the device for grinding dry products and grains, containing with a cone installed on it, a lid fixing on the body in inclined jaws, a bowl, a drive shaft with a sleeve and knives, is inserted a pusher and a fixer mounted on a bed between the body and the bowl with the possibility of longitudinal movement relative to the body, and a stopper movably connected to the pusher and installed in the groove of the body, the cover having a groove made above the retainer. -Latch and pusher are equipped with springs.

With this design, the housing can be mounted on the frame only with the lid closed, when the plunger pushes the protruding part of the stopper into the groove. When installed on the frame, the lock engages the groove of the lid and makes it impossible to remove it. This ensures the safety of the service, increases the operational POSSIBILITIES of the device.

20 In FIG. I shows a device for grinding dry products and grains (coffee grinder) - attachment to a universal kitchen machine, a general view; in fig. 2 - device with the cover removed, not installed on the drive.

The device comprises a frame 1 on which the housing 2, the lid 3, the bowl 4 are mounted. The bowl is fixed on the housing using inclined clamps 5. The drive shaft 7 with the coupling 8 and the knives 9 is mounted in the bearing 6 in the housing. The knives are fixed on the shaft 7 by means of a nut 10. On the bed 1 between the body 2 and the bowl 4, a retainer 11 is slidably mounted, which fits into a groove 12 made in the cover 3 above the retainer.

The latch 11 is provided with a spring 13 adjacent it to the frame 1.

The pusher 14 is mounted between the housing 2 and the bowl 4 with the possibility of movement in the axial direction and rests against the top; by its end 15, the cover 3. The stopper 16 is installed in the groove 17 of the housing 2 with the possibility of interleaving along it and provided with a spring 18, which expands a stopper from a groove 17. The stopper has an inclined surface 19 through which ocyniec T is its mobile connection with the pusher 14 and abut against which the pusher 14 holds the stopper 16 in the groove 17. In the frame, there is an actuator 20.

The coupling 21 of the output shaft 22 of the actuator 20 engages with the coupling 8 of the shaft 7.

The device works as follows.

When the drive 20 is turned on, the rotation from the output shaft 22 through the coupling sleeves 21 and 8 and the shaft 7 is transferred to the knives 9. Rotating, the knives crush the product that is more often 4. In this case, since the latch 11 enters the groove 12 of the lid 3, the lid cannot be rotated and disengaged with the inclined clips 5. i.e. the lid cannot be removed from the case and, therefore, closes the cup 3 imis knives 9 from the operator.

When housing 2 is removed from frame 1 under the action of spring 13, retainer 11 emerges from groove 12 of cover 3, and when rotating, cover closes out of clips 5 and opens the thicket 4 for unloading or loading the product. When the cover is removed, the spring 18 pushes the stopper 16 and leads it out of the groove 17,

at the same time, through the inclined surface 19, the stopper 16 lifts the pusher 14 under the body 2. Since the stopper 16 protrudes from the groove 17, it prevents the installation of the body 2 on the frame 1 and the coupling 2 and 8 does not engage, i.e. That cover 3, rotation from drive 20 cannot be transmitted to knives 9.

When installing the cover on the case, the cover presses on the pusher 14, moving it in the axial direction. Pusher through the incline. 19, compressing the spring 18, moves the stopper 16 and the groove 17. In this case, the body 2 is mounted on the frame 1 and the lock 11 enters the groove 12 of the cover. The device is ready for operation.

Thus, due to the fact that the possibility of installing the body without a key on the frame, and removing the cover when the body is mounted on the base frame is eliminated, the possibility of the impact of the rotating knives on the operator is eliminated, the safety of the device maintenance is enhanced and its operational capabilities are extended.
