Technical Field
The utility model relates to the technical field of red date grading, in particular to an automatic red date grading mechanism.
Background
The Chinese date screening device is used for centralized classification and screening after Chinese dates are picked. The Chinese dates are picked and then are collected and piled in a warehouse or a drying dam. Due to the dates with different sizes, the market price difference is large. Therefore, screening equipment is needed to screen the Chinese dates quickly and efficiently.
Generally, two methods for grading red dates are available, one method is manual grading, the grading is easily affected by subjective factors of people, grading errors are large, efficiency is low, the direct contact chance between workers and the red dates is increased, and the sanitation and safety of food are affected. Automatic grading is divided into mechanical grading and photoelectric grading, and machine vision-based grading. The mechanical grading is designed according to the external size of the red dates, different gaps of a mechanical mechanism such as a drum type, a rolling rod type or a sieve hole type are used, the grading grade is single, and damage is easily caused in the grading process. The photoelectric type utilizes the time that the red date passes through the photoelectric sensing ware to judge the width of red date to carry out the classification, this kind of grading plant requires relatively higher to external environment, and efficiency effect is poor. And thirdly, collecting red date information by using machine vision for grading.
For pursuit of higher added value, a more elaborate screening means is required.
The existing mechanical grading generally has the following defects:
the equipment can only divide the Chinese dates into two types. If more than two types of screening are needed, the series connection of the conveyer belts is needed, the occupied area is large, and after the upper level is transmitted to the lower level, the Chinese dates are unevenly distributed on the lower level conveyer belt, so that the screening efficiency is low.
The conveying adopts chain transmission, the conveying speed is limited, and the noise in the production process is very large.
The grading speed is slow, and the structure of an actuating mechanism is complex.
When the Chinese dates are shoveled into the screening equipment, various impurities are sent into the screening equipment together, and the screening equipment does not have a separate impurity removal design, so that the workload of the subsequent finished product packaging process can be increased.
