Corn ear weight grading compressed air nozzle opening

Abstract

The invention belongs to the technical field of crop production, in particular to a corn ear weight grading compressed air nozzle opening. The corn ear weight grading compressed air nozzle opening comprises a first nozzle, wherein one end of the first nozzle is fixedly connected with a second nozzle, two air inlets which are distributed in parallel are formed in the middle of the outer surface ofthe front end of the first nozzle, a fixing block is fixedly connected between the two side-by-side air inlets, a partition baffle is fixedly mounted on the side wall of the middle part of an inner cavity of the second nozzle, and a noise reduction channel is arranged above the partition baffle and located in the inner cavity of the second nozzle. According to the corn ear weight grading compressed air nozzle opening, a plurality of compressed air passages are arranged in the second nozzle, so that airflow has a large speed when flowing through the nozzle, then the large impact force is obtained, and better work is facilitated; and a connecting plate is embedded in the inner layer of the second nozzle, the connecting plate is made of a high-strength alloy steel plate material, and the steel plate has high strength and hardness, so that the impact resistance of the second nozzle is improved.

Description

technical field [0001] The invention relates to the technical field of crop production, in particular to a corn ear weight-graded compressed air nozzle. Background technique [0002] With the gradual improvement of people's consumption ability, people pay more and more attention to green and healthy food. Under this demand, fresh corn ears with rich nutritional value are naturally favored by more and more people, and the market demand has given birth to With the emergence of corn ear processing enterprises, grading equipment for corn ears instead of corn kernels gradually appeared. The grading index of the intelligent corn ear weight classifier is the weight of the corn ear. The conveying unit transports the ears of corn to the weighing unit. On the one hand, the weighing unit continues to transport the ears of corn to the grading unit. On the other hand, it weighs the ears of corn and sends the weight information to the control unit. The compiled grading program judges th...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a corn ear weight-graded compressed air nozzle, which solves the problem that the nozzle usually adopts a cylindrical shape or a trumpet shape, and the pressure of the compressor will disperse quickly, resulting in the effect of the ejected airflow. The force is small, and the heavy corn ears will not be blown into the corresponding grading outlet, which will cause inconvenience in use, and the grading work cannot be better completed. Most of the nozzles are exposed to the air. After a long time, the surface will be oxidized due to metal oxidation. It is corroded, and at the same time, the high-velocity air will collide with the inner wall of the air outlet, causing a certain amount of noise pollution and affecting the comfort of use
