Chinese chestnut sorting system

Abstract

The invention provides a Chinese chestnut sorting system. Rapid transfer between the upstream and the downstream of chestnut kernels is achieved, the chestnut kernels are weighed on one-by-one basis in the transferring process, a hopper and a vibrating guide grooves are arranged in an upstream and downstream sequence in a connecting mode, and sensors are arranged on a machine frame and used for adopting whether conveying signals of materials on corresponding stations are conveyed to a processing control unit. First, the chestnut kernels in the hopper are fed to the vibration guide grooves, thesize of groove cavities of the vibrating guide grooves is designed in an adapting mode according to the size of the chestnut kernels, the chestnut kernels are arranged and arrive at upstream fixing supporting frames from the discharging end, a chestnut kernel is just arranged on each upstream fixing supporting frame in an accommodating mode, and the chestnut kernels arriving at downstream fixingsupporting frames are all the chestnut kernels with known weight or mass. The Chinese chestnut sorting system has the remarkable effects that the chestnut kernels are sequentially and quickly transferred to weighing stations to carry out weighing, and the weighed chestnut kernels still maintain the independent sorting state, so that a basic guarantee is provided for sorting the chestnut kernels.

Description

technical field [0001] The invention relates to the field of chestnut sorting. Background technique [0002] Chestnut is a very popular food for consumers. Chestnut can be roasted without shell, canned and processed into canned food for food, or baked as food material. There are so many ways to eat chestnut. For canned chestnuts, the processing generally goes through processes such as shelling, peeling (removing) the fruit coat, cleaning, and boiling. The basic problems of grading and weighing must be involved in the filling of canned chestnuts. For grading, the size and weight of chestnuts are usually manually graded before cooking, which inevitably costs a lot of labor and time, and The error is serious. In the prior art, devices or designs using images and weighing schemes have been disclosed. The efforts of technicians to implement grading and sorting of objects to be selected through weighing or image schemes have indeed solved the problem of sorting some materials. ...

AI Technical Summary

Problems solved by technology

[0003] The Chinese patent document "A Chestnut Sorting Device" (CN 201720978228.7) (hereinafter referred to as Document 1) believes that the existing technology cannot classify the appearance grades such as the degree of surface damage. Sorting, specifically speaking, is to classify and evaluate chestnuts in terms of size, color, and surface damage after image collection, and the object of evaluation is chestnuts with (partially hard) shells

This document 1 cannot solve the technical problem faced by the applicant, that is, the chestnut kernels after the fruit coat has been removed are sorted by weight grade

[0004] Chinese patent document "A weighing and sorting device for nuts" (CN 201920640280.0) (hereinafter referred to as document 2), the nuts are poured from the entrance on the right side of the moving box 9, and the servo motor 16 is started at this time, and the servo motor 16 is used to drive The rotating wheel 15, the turntable 14, and the screening roller 6 rotate together, and while the nuts are rolling on the screening roller 6, when the size of the nut is smaller than the inner diameter of the screening hole 7 on the current screening roller 6, it will be screened from the current moment. The sieving hole 7 on the roller 6 falls into the corresponding collection box 5, and the nuts that are larger than the inner diameter of the sieving hole 7 on the current screening roller 6, along with the rotation of the screening roller 6, are brought into the lower On a screening roller 6, sieve again until the screening is completed; it can be seen that document 2 is based on the sorting scheme of the rotating drum, which is the same for the sorting of chestnut kernels after the fruit coat is removed by the applicant. Nothing can be done, because the rotation of the drum in Document 2 is the premise of its screening. Although the chestnut kernels after the fruit coat is removed still have good strength, when they are thrown, dropped, and squeezed with the rotation of the drum, they will be seriously damaged. It is inevitable that the chestnut kernel after the fruit coat is removed. In addition, although there is little difference in the size of the fruit grains, there may be significant differences in the weight of the fruit grains due to the difference in density

The above solution still cannot solve or provide relevant technical inspiration to solve the technical problems faced by the present application, because in Document 3, firstly, the poultry eggs are pushed by the egg pushing chain teeth 31 and roll on the guide rail 32 to move forward stably, The realization of rolling forward depends on the specific spherical shape of the eggshell of the poultry egg. Obviously, it is impossible to roll the chestnut kernel after the peeled fruit coat. The shapes of the chestnut kernel after the peeled fruit coat are extremely diverse and irregular. , so it can be said that document 3 cannot realize the problem of chestnut kernel translocation from upstream to downstream that this application faces
