Corn sorting machine

Abstract

The invention relates to a corn sorting machine capable of dividing corns into three sorts, namely corns with the lengths of less than or equal to 150 millimeters, corns with the lengths of more than 150 millimeters and smaller than 200 millimeters and corns with the lengths of more than or equal to 200 millimeters, according to the lengths of the corns. Three major parts, namely a feeding part, a division part and a sorting part, are arranged on a steel structural rack, and are driven by six motors respectively. In the feeding part, the corns fall on a conveyor belt driven by a driving system consisting of a belt transmission device, a planetary gear speed reducer and a chain transmission device after being arranged through arrangement rollers in a hopper. In the division part, a vibrating frame reciprocally moves by virtue of a crank-connecting rod mechanism driven by the motor to divide the corns into rows in a vibrating way. In the sorting part, double rows of parallel conveyor belts are adopted, and after the corns reach the detection range of a sensor, detected corn length signals are transmitted to a PLC (programmable logic controller), cylinders are further controlled to move, and a discharging baffle plate is further driven to realize the sorting of the corns. According to the corn sorting machine, the manual sorting can be replaced, so that the efficiency is improved by more than 10 times; the corn sorting machine is low in construction cost and convenient to operate.

Description

technical field [0001] The utility model relates to a corn sorting machine, which sorts corn according to the length of the corn, and belongs to the field of agricultural machinery. Background technique [0002] Corn is an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world. As one of the three major grain varieties, it has played a great role in solving the problem of food and clothing for human beings. Today, corn is still an indispensable food on the table of people all over the world: in Mexico, the "hometown of corn", the annual consumption of "national dish" corn tortillas reaches as much as 12 million tons. Like to eat; in developed countries and regions, corn is also widely used as a source of iron, magnesium and other minerals necessary for the human body; in some poor countries and regions, corn is still a cheap food for people. Moreover, a variety of delicacies can be made with corn as a ra...

Problems solved by technology

However, corn has different lengths and sizes, which makes the corn non-staple food produced fail to meet the required requirements, so it is necessary to sort corn by category

Previously, people sorted corn by hand, and the sorting work was very cumbersome, and the workload was heavy, consuming a lot of manpower and material resources
