DETAILED DESCRIPTION OF THE INVENTION
[0025] In this detailed description, the subject matter is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.
[0026] In FIG. 1, a representative lateral view of the subject matter pre-cleaning system (1) is given. Accordingly, said pre-cleaning system (1) is configured to provide separation of particularly unshelled hazelnut from foreign substances. This pre-cleaning system (1) can be used after goods receiving in hazelnut processing plants. The foreign substances mentioned in the invention can be items like dust, empty hazelnut, stone, soil, big bag yarn, etc. which exist in the unshelled hazelnut cluster by means of various ways. In order to provide separation of such foreign substances from unshelled hazelnut, there is at least one first separation unit (10), at least one second separation unit (20) and at least one third separation unit (30) in the pre-cleaning system (1). As these separation units operate in a synchronized manner, the unshelled hazelnut is purified from foreign items.
[0027] In FIGS. 2 and 3, the representative frontal and lateral views of the first separation unit (10), provided in the subject matter pre-cleaning system (1), is given. Accordingly, said first separation unit (10) provides sieving and separating of foreign substances except acceptable dimensions of unshelled hazelnut. In order to be able realize this, the first separation unit (10) has at least one chamber (11) and a first goods inlet (12) and a first goods outlet (13) provided at mutual sides of said chamber (11). While unshelled hazelnut, having foreign substances therein, enter said first goods inlet (12), unshelled hazelnut, where dust existing therein is removed, exits said first goods outlet (13). This process is provided by means of at least one lower sieve (16) and at least one upper sieve (14) existing inside the chamber (11). Said lower sieve (16) and said upper sieve (14) are positioned one above the other in a parallel manner to each other inside the chamber (11). The sieving gap of the upper sieve (14) is wider than the sieving gap of the lower sieve (16). While the upper sieve (14) preferably has a passage gap of 25 mm, the lower sieve (16) has a passage gap of 5 mm. Thanks to this, while big-dimensioned items like big bag yarn, straw, garbage, coarse particles, tree branch are held on the upper sieve (14), the items like small-dimensioned tiny parts, broken product, duct, soil are separated at the lower sieve (16). The items, which remain between the lower sieve (16) and the upper sieve (14), are unshelled hazelnuts purified from foreign substances at least partially. The chamber (11) is positioned in an at least partially inclined form in order for the unshelled hazelnut to be advanced from the first goods inlet (12) towards the second goods inlet (21). Thanks to this, the unshelled hazelnut is advanced from one location to another location simply by means of the effect of gravity. Additionally, in a possible embodiment, the first separation unit (10) can be configured to be able to vibrate. Thanks to this, the unshelled hazelnut is distributed on the upper sieve (14) in a wider manner and is sieved in a more efficient manner. While the sieved items are advanced to the next step from the first goods outlet (13), the wastes, which exist at the upper sieve (14), are discharged through at least one upper sieve waste discharge part (15), and the wastes, which fall under the lower sieve (16), are discharged through at least one lower sieve waste discharge part (17).
[0028] In FIG. 4, a representative lateral view of the second separation unit (20), provided in the subject matter pre-cleaning system (1), is given. Said second separation unit (20) provides separation of foreign substances (low density particles like dust, shell parts and hollow hazelnut), which has specific weight lower than the specific weight of acceptable unshelled hazelnut, by means of an artificial air flow provided in at least one flow path (22) provided thereon. The second separation unit (20) is positioned at the continuation of the first separation unit (10). There is at least one second goods inlet (21) and at least one second goods outlet (24) in the second separation unit (20). The second goods inlet (21) is essentially provided at the end of the first goods outlet (13). The unshelled hazelnut, discharged through the first goods outlet (13), enters the second separation unit (20) through the second goods inlet (21). There is at least one first blowing part (23) and at least one first suction part (25) on at least one flow path (22) at the second separation unit (20). Said first blowing part (23) is preferably positioned at the side which is towards the gravity. Said first suction part (25) corresponds to the first blowing part (23). A continuous air flow is formed from the first blowing part (23) towards the first suction part (25). While air is given from the first blowing part (23), this air is suctioned through the first suction part (25). By means of this, the unshelled hazelnut is separated according to the specific weight thereof. There is at least one wall (27) between the first suction part (25) and the first blowing part (23). This wall (27) accelerates and decelerates air flow and provides adjustment of the separation process in the best manner. Said second goods outlet (24) essentially exists at the first blowing part (23) in the second separation unit (20). Despite the blowing, the unshelled hazelnuts which cannot be advanced to the first suction part (25), in other words, the cleaned unshelled hazelnut is discharged through the second goods outlet (24). The foreign substances, advanced to the first suction part (25) by means of the air flow which exists on the flow path (22), are discharged through at least one second waste discharge part (26) which exists at the first suction part (25).
[0029] In FIG. 5, a representative perspective view of the third separation unit (30), provided in the subject matter pre-cleaning system (1), is given. Said third separation unit (30) provides separation of foreign substances, which have specific weight which is higher than the specific weight of the unshelled hazelnut, by means of artificial air flow and convection. This mentioned foreign substance can be an item like soil, stone, etc. In order to provide this, there is at least one body (31) on the third separation unit (30) and there is at least one inverse stepped sieve (32) on said body (31). Said inverse stepped sieve (32) is positioned on the body (31) in an at least partially inclined manner. There is at least one third goods inlet (33) in the upper vicinity of the inverse stepped sieve (32). Said third goods inlet (33) is essentially associated with the second goods outlet (24). The unshelled hazelnut taken from the second goods inlet (21) is advanced to the third separation unit (30) by means of the third goods inlet (33). The unshelled hazelnut is continuously poured onto the inverse stepped sieve (32) through the third goods inlet (33). In a possible embodiment of the present invention, the inverse stepped sieve (32) is configured to be vibrated. The inverse stepped sieve (32) is inclined. There is at least one third goods outlet (34) at the part of the inverse stepped sieve (32) which is low. At the high part of the inverse stepped sieve (32), there is at least one third waste discharge part (35). Said third goods outlet (34) is the part where the unshelled hazelnut is purified from items like stone, soil having specific weight difference with respect to the unshelled hazelnut. Said third waste discharge part (35) is the part where foreign substances are removed from unshelled hazelnut and discharged. There is at least one second blowing part (37) and at least one second suction parts (36) in the third separation unit (30). This structure shows similarity to the structure provided in the second separation unit (20). The second blowing part (37) realizes blowing, which is in inverse direction with respect to gravity, to the inverse stepped sieve (32) at least partially. As a result of this, the unshelled hazelnut is separated at least partially from the inverse stepped sieve (32). Air suction process is realized such that this force is also supported by the suction part. Thanks to this, only the foreign substances, which have higher specific weight, remain on the inverse stepped sieve (32). In this case, the inverse stepped sieve (32) is moved towards the third waste discharge part (35) and provides discharge of the foreign substances and at the same time, it provides discharge of the unshelled hazelnuts through the third goods outlet (34).
[0030] By means of all these embodiments, the heavy, light, empty grained, coarse and tiny garbage, which can exist in the unshelled hazelnut, are separated and discharged. In this case, the unshelled hazelnuts can be advanced to the next step of the hazelnut processing plant in a cleaned form. In this embodiment, by means of the first separation unit (10), the second separation unit (20) and the third separation unit (30), the unshelled hazelnut is automatically cleaned from waste substance in various manners and by means of this, the dependency on human force is reduced, and more number of unshelled hazelnut is cleaned in unit time.
[0031] The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
