Description

one

The invention relates to the meat industry, in particular, to knives for making hides during the processing of livestock in mills.

Known knives for embroiling skins, consisting of a body, two toothed blades mounted on the sheath, its axis, and the mechanism for driving the blades into reciprocating motion. The dual eccentric of the mechanism is connected through intermediate and flexible shafts with an electric motor. Known knife uncomfortable in. maintenance and unreliable.

The purpose of the invention is to eliminate these disadvantages.

This is achieved by the fact that on the necks of the double eccentric are installed with the possibility of rotation of the inner and the outer cage. The latter have radial holes.

At the same time on each blade is firmly fixed a finger with a head, installed with the possibility of entering into one of the holes of the corresponding holder.

To fit and engage the finger with the inner collar, the body of one of the blades has an elongated, eccentric envelope around which the finger is fixed.

FIG. Figure 1 shows a knife with an electric motor and a protective cut-off device for it, its general appearance; in fig. 2 - knife, longitudinal section; on

FIG. 3 - view along arrow - A in FIG. 2; in fig. 4 - clip, plan view; in fig. 5 - double eccentric. The knife for skinning consists of the following main parts: body 1 with a removable lid 2 and handle 3, two cutting serrated blades 4, installed on a sliding sliding pox 5, and the blade drive mechanism is reciprocating. AfterNRII through promelotochny and flexible shafts 6 and 7 is connected to the electric motor 8.

The drive mechanism of the blades 4 for returnable movement includes a twin eccentric 9 screwed into the shaft

6, as well as the inner 10 and outer 11 clips mounted on the necks of the eccentric 9. The eccentric 9 on the necks has grooves (not shown) that contain split plane-ground spring removable washers 12 and 13 that serve to prevent the collapsing of the clips 10 and 11 while rotating the eccentric 9. The twin eccentric necks are separated by a cylindrical bridge to fix the clips 10 and 11 from mixing. The inner and outer sleeves 10 and 11 are made with several radially arranged through holes 14.

On the blade x 4 rigidly fixed on one finger 15. The head of one of the fingers is included

in the hole of the holder 11, the head of the other

into the hole of the cage 10 and thereby keep the cages 10 and 11 from circular rotation together with the eccentric 9. The diameter of the heads of the fingers 15 is equal to the diameter of the holes of the cages 10 and 11.

To fit and engage the fingers 15 of one of the blades 4 with the inner yoke 10, the blade body is made with an extended, circumscribing eccentric 9 section, on which the pin 15 is fixed. The fixed axis 5 is detachable and consists of a rod 16 screwed into the nut 17, which wearing sleeve 18.

The blades 4 are also attached to the sleeve 18. The nut is secured with a spring locking pin 19.

The intermediate shaft b serves to connect the eccentric 9 with the flexible shaft 7. It is installed in the housing 1 with the help of sleeves 20. One end of the shaft is screwed into the eccentric 9. The shaft 6 is screwed into the screw 21. The latter fixes the position of the intermediate shaft 6 with its collar longitudinal displacement. At the front end of the flexible shaft 7, the lug 22 is rigidly fixed, having a square hole into which the protruding end of the spanner 21 enters. The flexible shaft 7 is enclosed in armor 23 having a lug 24 at its end, which is fixed in the handle 3 of the housing 1 by the half finger 25.

The electric motor 8 is illuminated on the bracket 26, on which the protective-disconnecting device 27 is mounted.

The knife works as follows.

From the electric motor 8, the intermediate shaft 6 is rotatably driven by the flexible shaft 7, and with it the twin eccentric 9.

The clips 10 and II are kept from rotating with the eccentric, 14 heads of fingers entering their hole. In this case, the clips 10 and 11 receive a reciprocating movement in the opposite direction by an amount equal to two eccentricities of the eccentric 9 (for one OBO: the mouth of the ecocentric 9).

Each pz clips 10 and 11 through the fingers 15 causes the blade 4 to reciprocate.

When the eccentricity of eccentric 9 is equal to m 2, m m, the blades 4 are rotated by two teeth.

Subject invention

1. A nib for jigging, consisting of a body, two cutting gear blades mounted on a common axis and a blade drive mechanism in reciprocating swinging motion, the double eccentric of which is connected through an intermediate and flexible shaft with an electric motor the purpose of increasing reliability and ease of maintenance, on the necks of the dual eccentric, the inner and outer shafts are installed with the possibility of rotation, made with radially arranged holes, and a finger with a head is rigidly fixed on each blade th mounted to approach one of the openings in the respective cage.

2. The knife of claim 1, characterized in that for the insertion and engagement of a finger with the inner race, the body of one of the blades is made with a stretched, circumscribing eccentric portion, and the finger is fixed on the latter.
