Device for pumping read grapes from a fixed or movable vat to a storage container

The invention relates to a device for pumping read grapes from a stationary or movable one Bucket to a storage container.

Devices of the type in question are known in the form of an Archimedean screw in the lower part of a vat is arranged and on which the grapes are poured out so that they get into a pump that is below

a -But is arranged and on which the grapes be poured out in such a way that they get into a pump which is arranged below the end of the screw. To get in To get to the pump, the harvested grapes must be subjected to a change of direction by 90, which is flawless Loading of the pump leads to harmful accumulations of material. On the other hand, the rotor of the pump is controlled by the The worm hub is driven by a pinion gear, which complicates the construction of the device in question and has a detrimental effect on the cost price.

The improvements according to the present invention are intended to remedy the above-mentioned disadvantages and to be economical and provide reliable grape pumping apparatus.

The device according to the invention is characterized, that it contains a conveyor in the form of an Archimedean screw, which is fixed in a manner known per se at the bottom of a or movable chute is arranged and is partly in an upwardly open tube, partly in a tubular sleeve rotates, furthermore a pump, the body of which is clamped to the sleeve in connection with it through a lateral passage stands, the pump being provided with a rotor wedged on the hub of the Archimedean screw, means for driving the screw and the rotor, as well as others at the outlet of the

Pump arranged means to the return of the funded To prevent good.

The attached drawing with an execution game allows a better understanding of the invention, namely Figure 1 shows a longitudinal section through a device according to the invention FIG. 2 a section along line H-II of FIG. 2,

FIG. 3 is a view similar to that of FIG. 2, but with a different one Run creation and

4 shows the device according to Fig.l partially in section after a horizontal plane running through the screw housing.

As can be seen from Fig.l, the device according to the invention contains an Archimedean screw Ί, which rotates with part of its length in an upwardly open conveyor trough and has a v-shape in cross-section with a strongly rounded Seheitel. JPress channel 2 comprises a 'front wall 2a _on which the shaft 4 makes its storage 3 FSR of the screw il'! 'Opposite the front wall 2a is the channel 2 in a röhrförmige sleeve .5 about where they by means of bolts 6 secured! is. This sleeve is provided with an inner partition 7 which forms a second bearing 8 of the shaft 4. Beyond the wall 7 , in the opposite direction to the screw 1, ie on the left in the figure considered here, the sleeve 7 ends in a pump body 9 of generally cylindrical shape, the geometric axis of which coincides with that of the shaft 4. This pump body has an upwardly directed pipe socket 10 'which is connected to a flange 11

Α098Ί7 / 0770 " ⁴ "

Connection to a (not shown) conveyor pipe opens.

The body 9 is closed by a wall 12 which is expediently fastened by means of bolts 13 and a shoulder 14 in the middle, which forms the third bearing of the shaft 4 of the worm 1. On the one between the wall and the intermediate wall 7 of this hub is wedged a rotor 15 which is generally egg-shaped in cross-section, is formed (Fig.2).

The shaft 4 of the worm 1 is connected to a reduction gear with angled countershaft 16 (Fig.l), for example is driven by an electric motor 17, the task of which is of course also an explosion engine or even simpler the drive by a tractor can take over in the case of a movable chute.

The partition 7 is provided with a lateral opening 18 (FIG. 2) provided, which connects the sleeve 5 and the pump body 9 to one another and through which the conveyed by the screw 1 Grapes can get into the pump body. The latter has a rounded outer bulge 19 to the right of the opening 18, which merges into the sleeve 5 (Fig. 4) in such a way that a passage 20 with a slight and regular curvature is created, through which the conveyed material can reach the rotor 15 without the risk of plug formation.

9817/0770

At the lower part of the connecting piece 10, a base 21 is formed in the body 9, on which the end of a slide 22 of generally is articulated curved shape and its free end rests on "the outer edge of the rotor 15. This slide forms a flap in such a way that the goods conveyed by the rotor 15 rotating in the direction of arrow F do not enter the sub-chamber, or side. Opening 18 can return when passing through the space 23 located to the left of the runner.

Fig.3 shows the operation of this flap when the Runner 15 is in a substantially horizontal position.

An economical pumping device was hereby created, since the rotor of the pump is directly on the hub the Archimedes' screw is wedged and its mode of operation is particularly reliable because the conveyed material is direct to the Pump is transported without a sharp change in direction.

Claims (5)

Patent claims \ IJ Device for pumping read grapes, characterized in that it contains a conveyor in the form of an Archimedean screw, which is arranged in a manner known per se at the bottom of a fixed or movable vat and is partly in an upwardly open tube, partly in a rotates tubular sleeve, furthermore a pump, the body of which is clamped to the sleeve communicates with it through a lateral passage, the pump being provided with a rotor wedged on the shaft of the Archimedean worm, and means for driving the worm and the rotor, as well as further means arranged at the outlet of the pump to prevent the material to be conveyed from flowing back to the pump. 2. Apparatus according to claim 1, characterized that the worm is driven via a reduction gear by means of a motor firmly connected to the vat will. 3. Device according to claim 2, characterized in that that the means for preventing the return flow of the material conveyed by the pump from a flap in the form consist of a curved slide, one end of which is pivotably attached to the pump body, while its other free End with the egg-shaped circumference of the runner together- A09817 / 0770 works. . 4. Device according to one of the preceding claims, d a d u r c h g e k -en ti indicates that the Front wall of the tubular sleeve to which the pump is attached is, has a side opening through which the grape berries move to move under the influence of the pressure developed by the Archimedean snail, essentially in straight line to get into the pump body. 5. Apparatus according to claim 4, characterized in that that to the right of the opening of the sleeves "* intermediate wall of the pump body has a rounded bulge, which has a passage with less and more regular Forms a curvature through which the trambenberries can get to the runner. 409817/0770 Blank page
