A feeding device for crayfish sorting machine

Technical field

The invention relates to the technical field of crayfish processing, and in particular to a feeding device for a crayfish sorting machine.

Background technique

A rotary-type weight sorter is commonly used for crayfish sorting. This sorter can detect products with different weights during continuous operation and automatically classify them according to set weight levels. It can also automatically count and store data on the products.

The turntable weight sorting machine usually consists of an annular conveyor belt and a number of sorting buckets set on the annular conveyor belt. The sorting buckets are equipped with weight sensing devices. The crayfish are manually placed in the sorting buckets one by one, and then weighed. Divide crayfish into different grades according to weight to achieve sorting. Existing crayfish sorting machines are manually placed one by one, which requires a large amount of manual operation and low efficiency. The speed of manually placing crayfish is much lower than the speed of the conveyor belt, resulting in most of the sorting buckets on the conveyor belt being empty. , equipment utilization is low.

The beneficial effects of the present invention are:

1. After the crayfish is transferred to the transfer roller by the conveyor belt, the crayfish that are in contact with the roller surface of the transfer roller can be transferred forward. Therefore, under the action of the transfer roller, the crayfish accumulated together can be initially dispersed. By setting the number of transfer rollers, the crayfish dispersed by the transfer roller are arranged individually to avoid accumulation of crayfish on the transfer roller. The crayfish between two adjacent transfer rollers are arranged into strips one by one, and then the crayfish are arranged into strips one by one. Then it is transferred to the discharging roller by the conveying roller, and falls from the gap between the conveying roller and the discharging roller to the conveyor belt 2. The conveying direction of the conveyor belt 2 is perpendicular to the conveying direction of the conveying roller. The crayfish can be sent in one by one by the conveyor belt 2. Automatic feeding is realized in the sorting bucket of the sorting machine.

2. Set up multiple discharging rollers, and the discharging gap between adjacent discharging rollers gradually increases along the discharging direction. By setting up multiple discharging rollers, smaller crayfish will first be discharged from the one with smaller discharging gap. After falling between the discharging rollers, the larger crayfish will then fall from between the discharging rollers with a larger discharging gap, so that the crayfish can be further dispersed and the distance between the crayfish falling on the conveyor belt 2 will be larger. , which is helpful for putting crayfish into the sorting bucket one by one.

3. A feed hopper is provided at the feed end of the conveyor belt 1. There is a vibration motor at the bottom of the feed hopper. Through the vibration of the vibration motor, the crayfish in the feed hopper can slide to the conveyor belt 1. The operator only needs to pour the crayfish into the conveyor belt 1. Just put it into the hopper, it is easy to operate and has a high degree of automation.
