Description

The invention relates to the processing of food products, in particular, devices for separating the stalks and can be used in canned food processing plants for fruit and other agricultural products.

The aim of the invention is to increase the reliability of operation.

Figure 1 shows the proposed machine for separating the stalk, a general view; figure 2 - section aa in figure 1; on fig.Z - view B in figure 1; figure 4 - shows a variant of the machine, for example, with a flat roller web.

The machine for separating the stalks contains a base 1, a hopper 2 equipped with flaps 3, an actuator 4 and a slide 5, made in the form of a welded structure mounted on axis 6. On the upper plane of the scenes 5 an arcuate frame 7 with slide bearings 8 is installed, in which freely rotating rubber rollers 9 and 10 forming a roller web. The center of the circle, along the arc of which the frame 7 is located, coincides with the axis 6, which makes it possible to withstand a constant gap between the lower cut of the hopper 2 and the roller web. On the link 5, there is also mounted a pallet 11 for removal of the stalks, discharge chutes 12 located at the ends of the roller blade, and an electric motor 13. On the rollers 9 there are sprockets 14 connected by a chain 15 with the electric motor 13. The sprockets 14 can be mounted along both edges of the roller blade as shown in fig.

P:) In this case, the prod osusstrstpl kts with. noMoiiU K) two chains 13. This design allows the HcnojT i3OBaTb notiKH ring of a larger diameter than in the case when all the sprockets are located on one edge of the roller web.

The link 5 is connected to the drive 4 by a crank-and-crank mechanism (mechanism (drive) 16). At launch 1, there are additional flaps 17, which, like the flaps 3, are fitted with aprons 18 and are located across the direction of movement of the roller web. on the sides of the flaps external to the bunker, the fastening points 19 of the aprons 18 are located above the lower edge of the flaps. The aprons 18 are made of elastic fabric

material (rubber)

The machine works as follows.

When the motor 13 is turned on, the roller 9 through the chain 15 and the sprockets 14 is rotated, the rollers 10 rotate in the opposite direction due to the friction of the rollers 9. When the drive A is turned on, the rotational movement through the crank drive-rod mechanism 16 is converted into oscillating motion of the link 5 around axis 6. Fruits located in the hopper 2, under the influence of the moving web, emerge from under the bunker 2 in a single layer and roll down to the discharge tray 12, as the inclination angle of the web increases as the from the bunker, the speed of rolling increases, it prevents the formation of lumps and promotes free fruit, which improves the conditions for the seizure and detachment of the stalks by the rollers 9 and 10. The rigidity of the aprons 18 towards the raz1-ru ee trays 12 is insignificant and they do not hinder movement fruits. By means of the shutters 3, the clearance is adjusted depending on the size of the fruits, by which both the distribution of the fruits in one layer on a roller sheet is sintered. When the roller niinoT- is reversed to the described pr (m; ess is repeated at the opposite end of the web. The remaining flux is swept away by the aprons 18 in the unloading lot

which prevents the accumulation of the treated fruit in front of the bunker 2 during the reverse course of the roller web. Re- | The machine is driven by the crank mechanism 16 by changing the stroke of the roller blade. The technical advantages of the invention compared to the known one are in increasing the reliability of the machine design, since the swing of the roller blade is carried out smoothly, without vibrations and high dynamic loads.
