Problems solved by technology

[0004] 1. The live fish sorting process will struggle, and the manual operation process will easily damage the fish;
[0005] 2. If sorting is carried out by manual experience and hand-eye measurement, the accuracy rate is low;
[0006] 3. If manual weighing is used for sorting, the efficiency is low and the workload is heavy;
[0007] 4. Manual operation, it is difficult to realize the integration with the follow-up links, and it is difficult to realize automation

Embodiment

[0030] like Figure 1-7 As shown, the live fish weight sorting machine of the present embodiment includes parts such as rack guide rails 4, traction motion devices 7, sorting barrels 3, sorting door-type mechanisms 2, and motion weighing devices 6, among which:

[0031] There are multiple sorting barrels 3, all of which are arranged on the rack rails and can move along the rack rails. The bottom of the sorting barrel is provided with a passive opening and closing bottom plate 10, and the passive opening and closing bottom plate can be passively opened and closed, and is connected with the sorting barrel body through a hinge.

[0032] Both sides of the sorting barrel are provided with rolling mechanisms 9, which can restrict the movement of the sorting barrel on the rack rails. Correspondingly, the rack guide rail 4 is a stepped structure, and the sorting barrel is constrained to move on the rack rail by the rolling mechanism; A first constraining plate 4-3 and a second const...

Abstract

The invention relates to the field of automatic processing of fishery products, and is a weight sorting machine and a grading sorting method for live fish. It is arranged on the rack rail and moves along the rack rail under the action of the traction motion device. The sorting door type mechanism and the moving weighing device are both set on the rack rail; the moving weighing device obtains live fish and sorting buckets. The actual weight of the said object is estimated by the dynamic weighing mathematical model; the bottom of the sorting barrel is provided with a passive opening and closing bottom plate, when it moves to the sorting door-type mechanism, it cooperates with the opening and closing of the sorting door-type mechanism to realize the sorting barrel The bottom passive opening and closing. The invention can be applied to the sorting of live fish of various sizes, has the characteristics of non-destructive and continuous sorting, improves the efficiency and accuracy of manual sorting, and reduces the damage rate of live fish.

Description

technical field [0001] The invention relates to the field of automatic processing of fishery products, in particular to a live fish weight sorting machine and a grading sorting method. Background technique [0002] Aquatic products have always been important agricultural and sideline products in my country, especially fresh fish. Fresh fish are rich in a large amount of nutrients such as protein and inorganic salts, which are more and more favored by consumers. With the continuous expansion of aquatic trade, the demand for live aquatic products is increasing. Weight sorting is a routine operation for processing aquatic products. However, at present, most of the fish grading and sorting are still in the manual operation stage. Relying on the experience of the workers and the hand-eye measurement to classify the fish, the efficiency is low, the work intensity is high, and the sorting accuracy is low. And in order to facilitate the operation, improve the survival rate of live...
