Description

Technical Field

[0001] The utility model relates to the technical field of invertebrate sorting, in particular to a rice worm grading and sorting device. Background Art

[0002] Grainworms, scientifically known as Tylorrhynchus terochaetus, belong to the phylum Annelida, class Polychaeta, order Chrysomelidae, family Nereididae, and genus Tylorrhynchus. They are mainly distributed in the estuary areas of the southern coast of my country. Grainworms often live in rice fields or muddy mudflats in estuary areas. They usually float on the water surface in groups in spring and autumn when the rice seedlings are heading and flowering, hence the name. Grainworms are rich in nutrition and delicious. They are a well-known local specialty food with a long history. They are regarded as a water treasure in Guangdong, Guangxi, Fujian, Hong Kong, Macao and Southeast Asia. "Supplement to Compendium of Materia Medica" wrote: "Grain worms are common along the coasts of Fujian, Guangdong and Zhejiang. They are shaped like earthworms. Fujian people eat them with steamed eggs, or make them into a paste and serve them to guests as a delicacy. It is said that eating them can nourish the spleen and strengthen the stomach." Grain worms are known as "cordyceps in the water" because of their medicinal and edible properties. They have the medicinal effects of nourishing the spleen and stomach, replenishing qi and blood, and promoting diuresis and reducing swelling. They are deeply favored by diners and are in short supply in the market.

[0003] Although the natural resources of rice worms are gradually declining, their artificial breeding technology has made breakthroughs in recent years. Relying on mature factory seedling cultivation technology and ecological breeding models such as integrated rice field breeding and three-dimensional pond breeding, the industrial breeding and production of rice worms has been gradually realized. At present, the harvest of rice worms after breeding is mainly to wait for them to mature and float on the water surface, and then collect them with a sieve at the outlet with the water flow. The produced rice worms have problems such as inconsistent size and uneven specifications due to individual differences. At present, the grading and sorting of rice worms after harvesting mainly rely on manual selection, which is labor-intensive and time-consuming, and the sorting efficiency is low. There is an urgent need for a technical solution that can save manpower and has efficient sorting. Utility Model Content

[0034] The specific implementation method is now described as follows:

[0035] The utility model provides an embodiment of a worm classification and sorting device, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , comprising a stepless screen (3), a cover plate (5) and a grating box (6), wherein the grating box (6) comprises a box body (61) and a delivery bin (63), the upper end of the box body (61) is provided with an opening, the inner surface of the box wall (65) of the box body (61) is connected with four rectangular grading partitions (62) whose height is lower than the depth of the box body (61), a hook (64), a hole and a lamp (2) are provided on a box wall (65) of the box body (61) opposite to the grading partition (62); the outer surface of the box wall (65) where the hole is located is connected to the delivery bin (63), and the box wall (65) and the delivery bin (63) are connected through the hole; the lamp (2) is connected to the upper part of the hole; the hook (64) is connected to the lower edge of the hole, and the hook (64) is also connected to the inner surface of the box wall (65) directly opposite to the hole;

[0036] The stepless screen (3) comprises a long connecting rod (31), a short connecting rod (32) and a plurality of ropes (33), one end of the plurality of ropes (33) being connected to the outer wall of the long connecting rod (31) at equal intervals, and the other end of the plurality of ropes (33) being connected to the outer wall of the short connecting rod (32) at equal intervals; the short connecting rod (32) being connected to the lower edge of the hole via a hook (64); the long connecting rod (31) being connected to the inner surface of the box wall (65) directly opposite to the hole via a hook (64), and when the stepless screen (3) is connected to the inside of the box body (61), the plurality of ropes (33) are all in a taut state; the ropes (33) are in contact with the upper surface of the grading partition (62);

[0037] The cover plate (5) comprises a horizontal trapezoidal plate (51) and a vertical trapezoidal plate (52). The horizontal trapezoidal plate (51) and the vertical trapezoidal plate (52) are both in the shape of a right-angled trapezoid. A slot (511) is provided on the oblique side of the horizontal trapezoidal plate (51). The slot (511) is clamped with the upper edge of a box wall (65) of the box body (61). A groove (521) is provided on the oblique side of the vertical trapezoidal plate (52). The groove (521) is clamped with the upper end of the grading partition (62). The right-angled side of the horizontal trapezoidal plate (51) and the right-angled side of the vertical trapezoidal plate (52) are connected.

[0038] The principle of the utility model for sorting rice worms:

[0039] The principle of the utility model for sorting rice worms is mainly to utilize the photophobia of rice worms (1) to drive the rice worms (1) from the delivery bin (63) to the stepless screen (3), and the bottom of the box and the inner wall of the box wall (65) are set to be dark. When the rice worms (1) are driven forward along the stepless screen (3) by bright light, the rice worms (1) always want to drill down, and because the gap of the stepless screen (3) gradually increases as it moves away from the delivery bin (63), when the rice worms (1) pass through the stepless screen (3), the rice worms (1) are moved to the stepless screen (3). During the process of passing through the stepless screen (3), the rice worms (1) with a small body diameter first pass through the stepless screen (3) and enter the space separated by the grading partition (62) near the delivery bin (63), and the rice worms (1) with a large body diameter can only move forward a longer distance until they can pass through the stepless screen (3). Therefore, after the rice worms (1) with different body diameters pass through the stepless screen (3), the rice worms (1) with similar body diameters will fall into a certain space separated by the box body (61) to achieve classification.

[0040] When the utility model is used, water (4) that can cover the stepless screen (3) is first added into the box body (61), and then a proper amount (preferably not more than about two-thirds of the volume of the delivery bin) of rice worms (1) is put into the delivery bin (63), and then the light (2) is turned on (the rice worms dive under the stimulation of the light and gradually drill through the holes at the bottom of the delivery bin, and then climb onto the stepless screen). After a period of time, when there are no rice worms (1) in the delivery bin (63), the sorting is completed.

[0041] To take out the sorted rice worms (1), lift the cover plate (5) to remove it, then remove the long connecting rod (31) and the short connecting rod (32) from the hook (64), take the stepless screen (3) out of the box body (61), and then cover the insect storage space separated by the grading partition (62) with a small-hole net (the holes are smaller than the smallest rice worm body diameter), and gradually open the small-hole net to gradually pour out the sorted rice worms (1).

[0042] The above embodiments of the utility model are merely examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the utility model are still within the scope of protection of the utility model.
