DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

[0031] With reference to FIGS. 1-3, 5 and 7, a seed sorting machine 1 according to a preferred embodiment of the present invention comprises: a feeding area 10, a plurality of filtration units 11, a classification assembly 12, multiple guiding assemblies 13, a delivery unit 14, and at least one pressing rod 15.

[0032] The feeding area 10 includes a plurality of tilted plates 100 crisscross arranged therein so as to separate a first space 102 from a second space 104.

[0033] Each of the plurality of filtration units 11 is obliquely disposed below the feeding area 10 and includes multiple holding trays 110, a plurality of first partitions 112, any two adjacent of which are mounted on two sides of each of the multiple holding trays 110, and said each holding tray 110 has a filtering hole 114 formed between any two adjacent of the plurality of first partitions 112, wherein two first connection shafts 111 are inserted through the plurality of first partitions 112 so as to fix said each filtration unit 11. Referring to FIG. 3, said each holding tray 110 has a stepped portion 116 arranged on a bottom thereof and configured to define the filtering hole 114, and the stepped portion 116 has multiple peripheral sides 1160 which define a plurality of widths of the filtering hole 114 with each of the plurality of first partitions 112 so as to classify nuts (such as a variety of seeds, e.g. watermelon seeds) of various sizes quickly.

[0034] The classification assembly 12 is mounted below the plurality of filtration units 11, and the classification assembly 12 includes a classifying tray 120, multiple guide sheets 122 obliquely defined thereon and located below filtering holes 114 of the plurality of filtration units 11 respectively, and a plurality of outlets 124 arranged on the classifying tray 120 and located on distal ends of the multiple guide sheets 122 thereof individually.

[0035] Each of the multiple guiding assemblies 13 is obliquely arranged below the classification assembly 12, and said each guiding assembly 13 includes a holder 130 and multiple ribs 132 formed on the holder 130, wherein between any two adjacent of the multiple ribs 132 is defined a slot 134 corresponding to each of the plurality of outlets 124.

[0036] Thereby, the multiple guide sheets 122 of the classification assembly 12 are located below the filtering holes 114 respectively so that the seeds are classified and drop on the multiple guide sheets 122 based on their sizes, and the seeds are guided to the plurality of outlets 124 via the multiple guide sheets 122, wherein said each outlet 124 corresponds to the slot 134 between said any two adjacent ribs 132. In this embodiment, the filtering hole 114 of said each holding tray 110 has four widths, and each of the four widths of the filtering hole 114 is equal to each of four distances between each of four peripheral sides 1160 and said each first partition 112, hence the seeds individually drop on the multiple guide sheets 122 via the four widths of the filtering hole 114 based on their sizes, and the seeds drop into the slot 134 via the plurality of outlets 124 along the multiple guide sheets 122.

[0037] The delivery unit 14 includes a base 140 on which multiple V-shaped grooves 144 and multiple second partitions 142 are arranged, wherein between any two adjacent of the multiple second partitions 142 is defined each of the multiple V-shaped grooves 144, wherein the slot 134 corresponds to one or more of the multiple V-shaped grooves 144, a first of two opposite of the multiple second partitions 142 is higher than a second of the two opposite second partitions 142, and some of the multiple second partitions 142 higher than the others of the multiple second partitions 142 are connected together by ways of two second connection shafts 141. Thereby, the multiple V-shaped grooves 144 of the base 140 accommodate the seeds from the slot 134.

[0038] Each of the at least one pressing rod 15 is located beside open segments of the multiple V-shaped grooves 144 and includes a plurality of rollers 150 and multiple trenches 152, wherein each of the multiple trenches 152 is defined between any two adjacent of the multiple trenches 152 and corresponds to said each V-shaped grooves 144. In this embodiment, two pressing rods 15 are configured to crush shells of the seeds, wherein depths of the multiple trenches 152 correspond to the seeds of the various sizes respectively so that the shells of the seeds are crushed by the multiple trenches 152, wherein the depths of the multiple trenches 152 correspond to the multiple holding trays 110 of various sizes. Preferably, the seeds drop into the multiple trenches 152 of various depths from the slot 134 between said any two adjacent ribs 132 after being classified, hence the seeds are arranged and delivered based on their sizes by using the slot 134.

[0039] As shown in FIGS. 4 and 4A, the seed sorting machine 1 is used to classify the seeds and to crush the shells of the seeds, for example, the seeds are fed into the feeding area 10 and drop into the plurality of filtration units 11 flatly by way of the plurality of tilted plates 100 via the first space 102 and the second space 104, wherein the seeds are classified based on their sizes by using the filtering holes 114 of the multiple holding trays 110 (as illustrated in FIG. 3). In this embodiment, the four widths of the filtering hole 114 are 9 mm, 9.3 mm-10 mm, 10 mm-11 mm, and 11 mm-12 mm individually. Accordingly, the seeds drop on said each guiding assembly 13 via the filtering holes 114, each of the multiple guide sheets 122 is located below the filtering hole 114, and each of the plurality of outlets 124 is arranged on each of the distal ends of the multiple guide sheets 122, such that four filtering holes 114 correspond to four outlets 124, and one of the four outlets 124 represents one of the seeds in one size. In addition, said each outlet 124 corresponds to one of the multiple guiding assemblies 13, and the slot 134 guides the seeds in the same size to the delivery unit 14.

[0040] Referring to FIGS. 6 and 8, the shells of the seeds 3 are crushed by the at least one pressing rod 15 after being positioned through the delivery unit 14, wherein the at least one pressing rod 15 is driven by a motor 2, and one of the at least one pressing rod 15 is configured to hold the seeds 3 and has the multiple trenches 152 of various depths so as to correspond to the seeds 3 of the various sizes. For example, some of the multiple trenches 152 of larger depths accommodate some of the seeds 3 of larger sizes, and the others of the multiple trenches 152 of smaller depths house the other of the seeds 3 of smaller sizes. Thereby, the at least one pressing rod 15 crushes the shells of the seeds 3 of the various sizes by way of the multiple trenches 152 of the various depths respectively.

[0041] The seed sorting machine of the present invention delivers the seeds and crushes the shells of the seeds quickly and easily at low noises and failure rate. In addition, nutlets of the seeds are not crushed by the seed sorting machine and mix with seasoning completely, and the seed sorting machine facilities breeding and germination.

[0042] While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
