Description

Technical Field

[0001] The utility model relates to an agricultural machine, in particular to a self-propelled red date collecting and sorting machine. Background Art

[0002] Jujube is not only a delicious dried fruit but also has medicinal value. More than 7 million mu of land is planted in my country, of which more than 6 million mu is located in the southern part of Xinjiang. There are two main jujube harvesting devices on the market. One is to use negative pressure to suck jujube, jujube leaves and jujube branches on the ground into the machine and then winnow out the jujube and jujube leaves. This machine has low working efficiency, high energy consumption, and is prone to jujube broken branches blocking the machine. Another widely used device is a device that installs a fan on the screen. This device is low in price and energy consumption, and is widely used. However, people need to lift the jujube to a high position and throw it down during operation, which is laborious and requires eating dirt. In recent years, some institutions have also developed a device that rides astride a jujube tree, uses an exciter to shake the jujube onto the conveyor belt of the machine, and then winnows it. Due to the irregular height and row spacing of the jujube, it has not appeared on the market. Farmers are in urgent need of a jujube collection and sorting device with low cost, strong adaptability, less soil consumption and low energy consumption. Utility Model Content
