Description

For the harvest of certain products, such as beets or the like,

  machines of the type are known to several successive successive stations, which possess in line the various devices necessary for the various stages of the harvest, such as removal of the foliage, extirpation,

  separation of the land and loading of the turbules into the

  interior of suitable pick-up devices.

  The last of these steps, that is to say the loading of the turbules, takes place by means of vertical loaders, arranged

  at the back of the machine, which use a

  of transverse combs associated with the ends of a

  pair of endless chains, these combs collecting the

  cules fed to the bottom of the collector by the pre-

  and bringing them first upwards and then in correspondence of the upper end, inside a

  collection container or crate placed below the bag

  Exit: In a certain sense the beets are "thrown" out of the magazine in correspondence of the rotation that the combs perform above, by virtue of the centrifugal force. These combs are obtained by means of a plurality of elastically flexible wire teeth. eg spring steel, in order to allow continuity in the

  operation of the machine even during frequent

  that the combs encounter against the product when the product remains stuck and is prevented in any way

  in its race inside the same charger.

  It is true, however, that products close to the stem

  of support for combs, or those which are

  proximity to the center of rotation, are subject to a centrifugal force "launching" much lower than that acting

  products which are in correspondence with the former

  free end of the teeth; it follows that inside the container it is almost exclusively the most external products that are launched while the products

  more interiors can fall back inside the charger-

  carrier and be crammed with others arriving from harvesting devices; as a result the machine loses 2 - loading power or the loader combs, in order to overcome this situation, are forced to a speed

high rotation.

  The essential object of the present invention is consequently to

  to implement an improved loading device

  intended for the transport of agricultural products to

  this device allowing this operation to be

  that the same products can be "launched" outside the magazine without having to give the latter

  operating speeds are too high, the teeth of the

  transport systems can at the same time maintain elasticity

  This and other objects are achieved by the device object of the invention, of the type comprising a carrier

  continuously, without end, extending vertically,

  laying a plurality of spaced comb-shaped elements

  from one another and developing horizontally and trans-

  to the direction of movement of the loader, provided with a series of teeth, each of which is formed of a rod-shaped member fixed at its inner end,

  horizontal support rod of all teeth and

  carrying a first portion adjacent said rod, which extends inclined by ranport to the direction of movement of the conveyor and the side opposite to the direction of movement thereof, and also having a second portion which

  originates from the first and extends perpendicularly

stretch to said direction.

  According to a preferred embodiment, this device is

  characterized in that said rod-shaped element

  laying a wire of elastically flexible material wound in turns close to said inner end, these turns

  lying in a vertical plane comprising the said direc-

  movement, said second portion being in

  the same vertical plane comprising said int-end 6-

  FIG. 1 is a schematic perspective view of the

  positive charger object of the invention; Figures 2, 3, 4 respectively show a view of

  Referring to Figure 1, the charging device object of the invention consists of a continuous vertical conveyor

  harvest 10 arranged in support on the frame of the machine.

  Each comb 2 is formed of said rod 3 to which are fixed (for example by means of set screws 11, see Figure 2), a plurality of teeth 12 (see Figures 2, 3, 4) spaced one of the other of equal distance, obtained

  an elastically flexible wire, preferably steel with

  4 - Said first portion 12 c is inclined in the plane of Figure 3 by an angle Xe, always with respect to the direction, so that the second portion 12 d is placed in the same vertical plane containing the end inside 12 a. According to the device in question the tubers 8 from the devices intended for their eradication and the following elements intended to separate said tubers from the earth, indicated in 15 in the drawing, fall inside the frame containing 6 through the mouth 7 and are collected as and when combs 2 in motion and transported by

Figure 5).

  In this way all the products, in correspondence of the higher rotation are subjected to the highest centrifugal force, which gives the certainty that these are "thrown" through the outlet mouth 9 inside the

harvest box 10.

  In addition, the particular conformation in plan (see

  Figure 3) of the same teeth is such that it avoids the birth of

  torsion moments around the axis of the inner end 12a acting on the portion 12d because of the weight of the tubers bearing on them, while the series of turns 12b contributes to ensure sufficient elasticity

  In this way all the products, in correspon-
