[0034] In order to better improve the efficiency of torreya grandis classification, the present utility model provides a torreya grandis classification device. In the embodiment of the present utility model, the main body 1 refers to the main component of the torreya grandis classification device. An inlet mechanism 11, a classification chamber 12, and an outlet 13 are formed inside the main body 1. The inlet mechanism 11 is connected to the classification chamber 12, and the inlet mechanism 11 is used to provide torreya grandis for the classification mechanism 2 in the classification chamber 12 for classification. The classification chamber 12 is used for accommodating the classification mechanism 2. The outlet 13 is located at the bottom of the inlet bin 111.

[0036] Figure 3 Is the bottom view of the torreya grandis classification device according to an embodiment of the present utility model; Figure 4 Is the structural diagram of the sorting wheel of the torreya grandis classification device according to an embodiment of the present utility model; Please refer to Figure 3 and Figure 4 ;

[0037] In order to avoid possible interference caused by the tangential arrangement of the sorting wheels 21, another embodiment is provided. A gap is formed between two adjacent sorting wheels 21, and a limiting baffle is arranged in the gap. The limiting baffle is connected to the main body 1 and is used to prevent the torreya grandis from falling through the gap.

[0038] In one embodiment, the sorting wheel 21 includes a first sorting wheel 211, a second sorting wheel 212, and a third sorting wheel 213; the first sorting wheel 211, the second sorting wheel 212, and the third sorting wheel 213 are sequentially arranged and connected to the main body 1 facing the feeding mechanism 11; the first sorting wheel 211 is formed with a first filtering port 22, the second sorting wheel 212 is formed with a second filtering port 22, and the third sorting wheel 213 is formed with a third filtering port 22; the first filtering port 22 is smaller than the second filtering port 22, and the second filtering port 22 is smaller than the third filtering port 22.

[0039] In order to better classify torreya grandis according to its own characteristics, by consulting the data, it is found that the maximum diameter of the largest cross-section of about 86% of torreya grandis nutshells is 11-14 mm; generally, torreya grandis is divided into four grades, corresponding to torreya grandis with diameters of 11-12 cm, 12-13 cm, 13-14 cm, and greater than 14 cm respectively; therefore, in the embodiment of the present utility model, the sorting wheel 21 includes a first sorting wheel 211, a second sorting wheel 212, and a third sorting wheel 213; the first sorting wheel 211 is formed with a first filtering port 22, and the size of the first filtering port 22 can be 12 cm; the second sorting wheel 212 is formed with a second filtering port 22, and the size of the second filtering port 22 can be 13 cm; the third sorting wheel 213 is formed with a third filtering port 22, and the size of the third filtering port 22 can be 14 cm; further, a blanking space 214 is provided on the side of the third sorting wheel 213 facing away from the feeding mechanism 11, and torreya grandis with a diameter greater than 14 cm can roll into the discharge port 13 through the opening under the drive of the third sorting wheel 213, so as to achieve the four-level classification of torreya grandis. The first sorting wheel 211 is tangent to the second sorting wheel 212, and the second sorting wheel 212 is tangent to the third sorting wheel 213 to prevent torreya grandis from falling between the sorting wheels 21.

[0040] In one embodiment, the sorting wheel 21 is formed with a plurality of filtering ports 22.

[0041] In order to improve the filtering efficiency of the sorting wheel 21, in the embodiment of the present utility model, the sorting wheel 21 is formed with a plurality of filtering ports 22. Specifically, the sorting wheel 21 includes a disc 215 and a filtering rod 216. There are two discs 215, and the two discs 215 are symmetrically rotatably connected to the main body 1. One of the two discs 215 can be the driving wheel and the other can be the driven wheel to drive the sorting wheel 21 to rotate. The disc 215 is rotatably connected to the main body 1 and can rotate relative to the main body 1 under the drive of the driving member. Specifically, it rotates away from the feeding mechanism 11. A number of sorting rods are circumferentially connected between the two discs 215, and a specified distance is provided between every two adjacent sorting rods. Specifically, the rectangle formed by the cooperation of two adjacent sorting rods and the two discs 215 is the filtering port 22, and the sorting wheel 21 is a circle surrounded by a number of filtering ports 22, so as to improve the filtering efficiency. Each torreya grandis entering the sorting wheel 21 can contact the filtering port 22, and when the sorting wheel 21 rotates, the posture of the torreya grandis in the filtering port 22 can be adjusted, so that the torreya grandis within the specified size range can enter the discharge port 13 through the sorting wheel 21. And through the arrangement of the sorting rods, the torreya grandis larger than the specified size can be clamped by the two sorting rods and move synchronously with the sorting wheel 21, so as to enter the next sorting wheel 21 or the blanking space 214 under the drive of the sorting wheel 21, thereby improving the transfer efficiency of the torreya grandis. When it cannot enter the feeding port through the screening port, it can quickly move into the next sorting wheel 21 through the cooperation of the sorting rods.

[0042] In one embodiment, the feeding mechanism 11 includes a feeding bin 111 and a feeding cylinder 112. A number of accommodating grooves 1121 are formed on the feeding cylinder 112. The feeding bin 111 is located on the first side of the feeding cylinder 112, and the grading chamber 12 is located on the second side of the feeding cylinder 112. The feeding cylinder 112 is rotatably connected to the main body 1 and can bring the torreya grandis in the feeding bin 111 into the grading chamber 12 through the accommodating grooves 1121 during rotation.

[0043] In order to enable torreya grandis to enter the sorting wheel 21 horizontally, in the embodiment of the present utility model, the feeding mechanism 11 includes a feeding bin 111 and a feeding cylinder 112. The feeding cylinder 112 can be a cylindrical structure formed with a plurality of accommodating grooves 1121 for accommodating torreya grandis. The setting of the cylindrical structure can facilitate its rotational connection with the main body 1. The feeding bin 111 is located on the first side of the feeding cylinder 112. The feeding cylinder 112 is circumferentially provided with multiple columns of accommodating grooves 1121, and each column of accommodating grooves 1121 can also be multiple accommodating grooves 1121. Specifically, the number of columns and the number of each column can be multiple. A large number of torreya grandis are input into the feeding bin 111, and the feeding cylinder 112 can uniformly input torreya grandis into the sorting mechanism, thereby avoiding the stacking of torreya grandis on the sorting wheel 21 and the mutual jamming between torreya grandis, which may cause smaller-sized torreya grandis to enter the filtering openings of higher sizes, thus affecting the sorting accuracy. The grading chamber 12 is located on the second side of the feeding cylinder 112 and can bring the torreya grandis in the feeding bin 111 into the grading chamber 12 through the accommodating grooves 1121 during rotation. Further, by providing rows of accommodating grooves 1121 on the feeding cylinder 112, torreya grandis can enter the sorting mechanism in a whole row according to the arrangement order of the accommodating grooves 1121 for sorting, thereby preventing torreya grandis from overlapping on the sorting wheel. The feeding bin 111 can be provided with a feeding port, and the feeding cylinder 112 is embedded in the feeding port. Under the action of gravity, torreya grandis enter the grooves of the rotating feeding cylinder 112, and under the rotation of the feeding cylinder 112, they move to the second side of the feeding cylinder 112 and enter above the sorting wheel 21 of the grading chamber 12 under the action of gravity. The axial length of the accommodating groove 1121 on the feeding cylinder 112 is greater than the circumferential length of the accommodating groove 1121 on the feeding cylinder 112, so as to ensure that torreya grandis enter the accommodating groove 1121 horizontally, which is convenient for subsequent grading and avoids torreya grandis entering the sorting wheel 21 longitudinally and being stuck between the sorting rods of the sorting wheel 21, thus affecting the sorting accuracy. Specifically, by referring to the data, about 86% of the maximum diameters of the largest cross-sections of torreya grandis nut shells are 11 - 14 mm; 76% of the lengths of torreya grandis nut shells are 27 - 32 mm. Therefore, the accommodating groove 1121 can be a groove with a size of 40×20×20 mm, ensuring that only one horizontally placed torreya grandis nut can be accommodated. At the same time, in cooperation with the hopper, only the torreya grandis falling into the groove will be transported to the sorting wheel 21.

[0044] Among them, the feeding cylinder 112 is also driven by a driving motor. Specifically, it can be controlled by a single independent machine; or the driving motor can drive three sorting wheels 21 and one feeding cylinder 112 to rotate in cooperation with transmission parts. Specifically, it can be connected by a chain, and the transmission ratio is 1 - 1 - 1, so that the rotation speeds of the three sorting wheels 21 are the same, thus better realizing grading.
