Definitions

  • This invention relates to trailers or automotive vehicles fitted with a special mechanism which, on the basis of a particular method, is used in the cleaning of sand on beaches from various types of waste.
  • the sand beach waste cleaning mechanisms are internationally known to be fitted with a rotary cylinder (rotor) which operates in a manner which ejects and propels the sand together with the waste onto a rolling conveyor belt so that after screening the waste collected will be discharged in the usual manner into waste buckets.
  • a rotary cylinder rotor
  • Mechanisms which, with the assistance of a sphenoid blade, excavate the sand with the waste and drive it towards a conveyor belt so that again, after screening, the waste is removed, are also internationally known.
  • Such mechanisms and/or combinations of such mechanisms with the previous mechanisms fitted with rotor are mentioned in Patents, e.g. US 2002170765, JP 2004324399, US 6094847, JP 4174114 and 0 486 053 Bl.
  • the advantage of this invention is that the method of sand - waste separation is carried out in two particular phases.
  • the first work phase by means of the rotor (2) rotating in the direction of the arrow (16), while the mechanism moves in the direction of the arrow (15), all the waste together with a minimum amount of sand is guided to a moving, vibrating conveyor belt/screen (5) following which the waste is deposited into a waste bucket, whilst during the second work phase, the larger quantity of sand, now cleaned, bypasses the sphenoid blade (1) and is deposited on the ground without the need of screening since it is already clean.
  • This method of waste separation through the two work phases of the invention is achieved with a special mechanism which is also the particular advantage of this invention.
  • the invention achieves, apart from an excellent quality of cleaning, much greater productivity in comparison to other well-known mechanisms having the same power and energy consumption.
  • the remaining quantity of sand which is significantly greater located in front of the sphenoid blade (1), and, whilst this blade moves forward, the sand passes over the blade through the fixed gap/window created by the distance between the blade and the edge of the conveyor belt (5), and falls down on the ground without guiding it towards the screen since it is already cleaned sand.
  • the described method for cleaning beach sand in this invention is superior from the point of view of energy consumption to the well known methods of stirring up, loading and screening all the quantity of sand designated by the working depth because according to the invention there is no requirement to load and screen the greater proportion of the processed sand.
  • Another additional advantage of the method of sand cleaning utilized in this invention is the reduced requirement for screening surface or conveyor belt /screen because a very small section of the sand now requires separation from the waste through screening, since the greater quantity of waste has already been collected during the first work phase, e.g. throughout the stages of stirring and ejection.
  • the rotor (2) which is made up of a metal cylinder (14), fitted out with metal spikes (3) the edges of which terminate to a cylindrical surface of a suitable diameter so as to meet the demands of working depth (H).
  • the spikes are fixed equidistantly along a line parallel to the cylinder's axis either in a helicoid line.
  • Figure 1 shows the rotor (2) of the invention's mechanism for the stirring up the sand with, preferably, 5 (five) series of spikes.
  • the length of the spikes should preferably be approximately 60% of the radius of the cylindrical surface.
  • the edge of each spike during its rotation passes over the cylindrical surface with an axis equal to the rotors width.
  • the number of spikes, the distance between the spikes in a series and the location of the spike series are allocated so that a gap of approximately lmm is left between the trace of the spikes on the ground, all over the working width.
  • This constructional configuration allows the collection of even smaller pieces of waste.
  • the rotor rotates at a steady speed around the axle (6) in the direction of the arrow (16), whilst the mechanism, fitted to an automotive vehicle or trailer, moves in the direction of the arrow (15).
  • the axle (6) is firmly supported on the sheer supports of the casing (13) which, at the same time, constitutes the frame of the mechanism. b).
  • the sphenoid blade (1) (also referred to as a "knife” or “blade”), together with the rotor (2) designate the working depth. It has, according to this invention, a cylindrical form on its upper surface, so as to have a stable distance from the cylindrical surface designated by the edge of the spikes (2) of approximately 4mm so as to be able to collect even smaller pieces of waste, such as, e.g. cigarette butts.
  • the sphenoid blade extends to the front surface in an acute peak whilst, for reasons of resistance, the rear surface of its cross-section is wider. It is constructed of reinforced steel or other similar material of high resistance to abrasion or bending and, according to requirements, it may also be perforated.
  • the surface (7) is configured cylindrically with a relatively large radius. It is metallic as is the whole casing.
  • Fig. 1 shows the place in lineal where the waste are ejected (they are marked with squares or circles), as well as those that are ejected from the internal surface (7) of the casing. e).
  • the conveyor belt (5) is fashioned in the form of a mesh grid or as a standard conveyor belt, or as a screen/shaking belt and as a belt with in-between hooks which increases the possibility of transporting waste at a sufficiently greater height, and with lateral supports which ensure the protection of the belt against any wear and tear.
  • the conveyor belt moves and vibrates within the framework (9) via direct and concentric rubber rollers.
  • the lower section is supported on bases of plastic wheel supports which are housed on the sides of the frame (9).
  • the frame (9) has a high inclination at its beginning and a lower one on its end which is followed by the belt in such a manner that the collection of waste and its transfer will be more accurate. The transfer in the higher inclination is supplemented by hooks fitted to the belt.
  • the frame (11) can be a section of the frame of a trailer vehicle or an automotive vehicle. According to requirements it could be a wheeled vehicle (4x4, 6x6, 8x8) moving on all wheels or a crawled vehicle even fitted with a waste collection and transfer container.

Abstract

La présente invention concerne un procédé se composant de deux phases de travail distinctes. Pendant la première phase, le sable devant être nettoyé est soulevé par un rotor (2) qui tourne à une vitesse de rotation constante tandis que le mécanisme passe sur la surface de sable à nettoyer. Lors du soulèvement, les déchets, rencontrés sur toute la profondeur de travail, sont rejetés sur un bande transporteuse (5) avec une petite quantité de sable soulevé, puis sont conduits vers des tamis où le sable est séparé et les déchets restant sont rejetés dans un baquet destiné aux déchets. Lors de la seconde phase de travail, la plus grande partie du sable soulevé, qui est propre maintenant, se déplace selon un écoulement (12) entre la lame sphénoïde (1) et la bande transporteuse, sans contenir un seul déchet, et distribuée sur le sol. Cette invention présente les avantages suivants : elle permet de réduire la consommation d’énergie et améliore les capacités de nettoyage des machines employées pour nettoyer le sable de la plage.
