Description

Device and method for stripping beet depreciation.

  The invention relates to a device and a method for leaf stripping with beet amortization, the device being of the type comprising a rotated axis or rotor powered from a motor, such as a rotor connected to a three-point socket d '' a tractor, this axis supporting cutting tools adjusted to a certain height from the ground to cut the

  upper part of beets and especially the leaves.

  There are already known a number of stripping devices which are very aggressive and which do not make it possible, by adjusting these devices at ground level, to stripping the lowest beets. Thus, stripping devices are known comprising a rotor on which are

  fixed rigid rubber bats.

  These traditional devices are difficult to adjust and do not allow effective stripping, especially for beets deeply sunk in the ground for which stripping is not complete, while for beets little sunk in the ground, the latter are

  beheaded, resulting in a loss of raw material.

  In an attempt to limit the destructive effect of these tools, stripping devices with several rotors have been provided allowing the use of straight and fine bats, this multiplication of rotors allowing a finer approach to integral stripping, without however reaching

desired efficiency.

  These already known devices have a very high cost price and do not give a satisfactory result. Indeed, because of their aggressiveness, it is necessary to adjust these devices according to a medium setting leaving leaves on the most sunken beets, while they completely scalp beets little sunk in the ground. This poor stripping quality determined the establishment by the sugar factories, of a penalty of 10 to 15% of the production delivered by the beet growers. This penalty corresponding to a

  tax calculated based on the weight of sheets delivered.

  In addition, the leaves delivered to the sweets and removed for cleaning, before sugar production, create a product which, mixed with the

  earth, corresponds to a polluting product due to the fermentations generated.

  Thus, a medium-sized sugar refinery produces 500 tonnes per day of

  pollutant mixtures that the current structures do not allow to treat.

  Patent 93 02 901 also discloses a method and a device for disbudding plants, such as blackcurrants, the main characteristic of which is to use at least one rotary shelling tool against all or part of the stem, the stems. being moved in translation along their length, each rotary shelling tool having a tangential speed at the point of contact with the surface of the rods at least greater than the speed of longitudinal movement of the rods having the same direction and the same direction as the tangential speed of the tool, the parallel or perpendicular control device being provided with several shelling tools arranged in line in the direction of the length of the stems to be disbudded. Such a method and such a device are not easily applicable and insufficiently effective when applied to

beets.

  The object of the present invention is to eliminate these drawbacks and to create an effective beet depreciation stripping device and method making it possible to eliminate the drawbacks associated with the remaining beet leaves and by increasing the production yield by delivering beets perfectly. leafless. To achieve such goals, the present invention is based on the main characteristic of the beet depreciation stripping device according to which the axis rotated is provided with flexible stripping bats, each of the stripping beats forming a loop the free deformable or curved end of which strikes the top of the beets in a cushioned manner to cut the leaves, without

  start the beets themselves.

  Such a simple design device makes it possible to reduce production costs and at the same time increase the productivity of

products delivered to sugar factories.

  According to another characteristic of the invention, the stripping bats are mounted on the axis so as to be angularly offset from one another.

  This improves the effectiveness of stripping.

  According to another characteristic of the invention, the stripping bats are mounted on the axis, so as to form a

group of bats.

  According to another characteristic of the invention, each

  group of stripping bats corresponds to a row of beets.

  According to another characteristic of the invention, the bats or the groups of stripping bats are mounted on at least two

  axes rotated, in an identical or opposite direction of rotation.

  According to a characteristic of the invention, the bats or the groups of stripping bats are made up of circular bands rotated by the axis when the worn areas are replaced.

by a new area.

  According to another characteristic of the invention, the bats or groups of stripping bats consist of flat, curved or curved strips, each strip of reel of a first reel to fill a second reel with the worn areas, the reels being Connected to each other by a mechanism on the rotor According to another characteristic of the invention, the device consists of at least two axes carrying the bats or the groups of stripping bats, these axes rotating on themselves, being displaced parallel or perpendicular to the rows of

leaf beets.

  The invention is also based on the characteristics of the process allowing the implementation of the beet stripping device, according to which the stripping of the beets is carried out by moving rotary axes along the rows of beets, these axes carrying bats. or groups of curved or flexible stripping bats, coming

  hit the top of the beets in a cushioned fashion.

  According to Figure 8, the stripping device (29) consists of an axis or rotor (30) on which are mounted three groups of stripping sticks (31), (32), (33). The groups of stripping sticks (31), (32), (33) are arranged at 120 relative to each other on the axis or rotor

  (30). This constitutes a third embodiment of the device.

  According to Figure 9, the stripping device (34) consists of an axis or rotor (35) on which are mounted four groups of stripping sticks (36), (37), (38), (39) , arranged perpendicular to

    relative to each other. This constitutes a fourth embodiment.

tion of the device.

  According to FIG. 10, the stripping device (40) consists of an axis (41) on which are stripping strips (42), (43) arranged perpendicularly to each other and (44), (45) also arranged perpendicular to one another; these two groups formed by the bats (42), (43) on the one hand, the bats (44), (45) on the other hand are also offset longitudinally on the axis of the rotor (41) This constitutes a fifth embodiment of the device. According to FIG. 11, the device consists of an axis or rotor (47) on which are stripped strippers (48), (49) arranged at 180 ° one from, thus the strikes (50), ( 51) also forming between them a flat angle of 180, the two groups formed, on the one hand by the bats '48), (49), on the other hand by the group of bats (50), (51) are offset angularly and longitudinally with respect to each other on the axis or

  rotor (47). This is a sixth embodiment of the stripping device.

  According to FIG. 12, the stripping device (60), seen from above, is suitable for stripping 6 rows of beets and composed of an axis or rotor (61) carrying groups of stripping bats (62 ). It is possible to rotate the axis or rotor (60) or (61) alternately in one direction or another. The rotor (61) is further displaced, along the advancement arrow H, which determines an effective stripping of 6 rows of beets (63) stripped, while the beets (64) are

being stripped.

  According to FIG. 13, the stripping device (70) consists of the axis or rotor (71) drives in rotation, according to arrow I. The axis or rotor (71) carries a group of stripping bats ( 72), the flexible and curved ends of which closely match the profile of the beet (73), so as to obtain effective stripping without damaging the beet

(73) proper.

  According to FIG. 14, the stripping device (80) is composed of a rotor (81) carrying two groups (82) of stripping bats. It is possible to perform the stripping to rotate the axis or rotor (81) according to the arrows J or K1 the direction of advance of the entire device taking place according to arrow L. In this embodiment , the axis or rotor (81) is moved perpendicular to the rows (83), (84) of beets. According to Figure 15, the stripping device (90) consists of two axes or rotors (91) (92) mounted in parallel and rotated in opposite directions to each other Each of the axes or rotors (91 ) carry groups of stripping bats According to this embodiment, the device (90) moves, according to the direction of advance corresponding to the arrow M. The axes or rotors (91), (92) of the device being moved

  parallel to the rows (93) of beet to be stripped.

  According to Figure 16, the stripping device (90) consists in particular of two axes or rotors (91), (92) carrying the groups of stripping bats (94) can be rotated in one direction or in one other. According to this particular embodiment, the

  bat groups (94) are rotated in the same direction of ro-

  tation of the axes (91), (92). In addition, the bat groups (94) of the axis or rotor (91) are angularly offset by 90 relative to the bat groups (94) carried by the axis (92), but can be mounted according to the

  other figures described above.

  According to Figure 17, the stripping device (100) consists of an axis or rotor (101) causing the cutting strips to rotate (102), (103). The flexible cutting strips (102) (103) have a free end corresponding to a wear zone (104), since this zone strikes the top of the beets to be stripped. This particular embodiment makes it possible, by stepwise rotation of the strips (102), (103) controlled by the rotation of the shafts (105), (106) to move the wear area and to renew the contact surface. of

  strips (102), (103) on the beets to be stripped.

  The stripping device (100) operates either by tightening the strips (102), (103) between the shaft (106) and the axis of the rotor (101), or by leaving the strips (102), (103) free and without tightening during

rotation of the device.

  The wear zone is adjusted step by step and as soon as it is observed when the device is in tight mode. In free function, the bands (102) (103) are rotated on themselves and the wear point is in permanent rotation. The strips (102), (103) are intended to be packaged and sold in the form of a removable "exchange kit" as described below. This allows better interchangeability of the bands once worn. According to Figure 18, the stripping device (110) consists of a shaft or rotor (111) rotating and looping the flexible bands (112), (113) whose free and flexible ends (114) constitute also the zone of wear of the strip forming the stripping bats. Each strip (112), (113) is capable of being rotated and unwound from a first full reel (115) to a second empty filling reel (116) by means of a pinion-like mechanism allowing the movement of the wear area (114). Thus, each strip (112), (113) unwinds from the reels (115) towards the reels (116) after wear of the wear face (114). This device (110) is therefore provided with a distribution device constituted by the coils (115), (116) and the pinion (117) for the controlled unwinding of the coils (115) and pinion (117) for the controlled unwinding of the coils (115) and the winding of the empty coil (116) which

recovers used areas.

  The strips (112), (113) are packaged in the form of coils. Each strip is made of a flexible, flat material with a certain width such as rubber, polyurethane, etc. Each reel includes a multitude of flexible, flat strips wound side by side. The flexible bands can be made of any material whose hardness will be low, so as not to attack beets (leather, synthetic materials, light metals ...). After a certain number of working hours or order the

  rotation of the coils carrying the strips (112), (113) so as to

  empty the full spool and rewind the worn strips by winding it up on the empty spool. The bats or groups of stripping bats are made up, in particular according to FIGS. 17 to 19, of circular bands (102), (103) rotated by the axis (105), 106) at the time of

  replacement of worn areas (104) with a new area.

  Bats or groups of stripping bats also consist of flat, curved or curved strips (112), (114) each strip unwinding from a first reel (115) to fill a second reel (116) with the worn areas , the coils (115), (116)

  being connected together by a mechanism (117) on the rotor (111).

  Bats or groups of bats have a smooth surface. They can also have more aggressive surfaces and can be provided with pins or notches. This allows leaf stripping in bad weather conditions such as frost, snow, etc ... The bats or groups of bats can be made

  in materials such as rubber or polyurethane.

  According to Figure 19, the exchange kit (120) is mounted,

  removably, on the rotor (121).

  According to Figure 20, the rotor (121) is provided with an opening (122) which receives the tape exchange kit (120). The control shaft (123) carries the roller (124) which ensures the rotation of the strip (125). The tape exchange kit (120) is mounted on the rotor (121)

by screwing or clipping.

  According to FIG. 21, the axis (140) for driving the rollers (124) is set in differential rotation with respect to the rotor (121) only when the machine user controls the rotation of the belt to retract the worn areas. In the case of leaf stripping, the axis (140) rotates at the speed of the rotor. Another version allows permanent differential rotation of the axis (122) relative to the rotor (121) thus allowing the bands (125) to rotate around the axes (127) in

  permanence. This device allows more suitable wear of the axle (127).

  This axis (140) carries the roller (124) whose rotary movement causes the

  strip (125) by means of pins (126), (127) wedging or gripping

  rant the strip (125). The strip exchange kit (120) is further provided with sealing flaps (128) at the level of the passage of the strip (125).

  in the block (129) of the exchange kit (120).

  According to Figure 22, the rotor (130) cooperates with a game

  coils (134), (135) carrying the strips (132) mounted side by side.

  After the strips (132) have worn out in the area (133), the coils (134), (135) are rotated so as to obtain the unwinding of the strips (132). We get the unwinding of the tape

  full (134) and the winding of the worn areas on the coil (135).

  The coil set replacement (131) will be carried out after complete wear

bands (132).
