Chinese date picking machine for separating impurities successively

Abstract

The invention discloses a Chinese date picking machine for separating impurities successively. The machine comprises a fruit containing box and an air suction pipe, wherein the air suction pipe comprises an outer PVC pipe, an inner PVC pipe, a lower corrugated hose and an upper corrugated hose, the two ends of the inner PVC pipe are connected with the upper corrugated hose and the lower corrugated hose respectively, the outer PVC pipe is fixedly arranged on the inner PVC pipe in a sleeving mode, a closed soil collecting box is formed by the outer PVC pipe and the inner PVC pipe, filtering holes are formed in the inner PVC pipe, and an opening and closing type outlet is formed in the outer PVC pipe; a guiding plate and a direction guiding plate are arranged in the fruit containing box, one end of the guiding plate is fixed to the position below the joint of the air suction pipe and the fruit containing box, the other end of the guiding plate inclines downwards and is arranged above a fruit containing basket, one end of the direction guiding plate is fixed to the position below the joint of the sedimentation chamber and the fruit containing basket, the other end of the direction guiding plate inclines downward and is arranged below the lower end of the guiding plate, and a gap for red dates to pass through is formed between the guiding plate and the direction guiding plate. Through the picking machine, soil and grass leaves can be separated successively when the red dates are picked, and it is guaranteed that the red dates can be separated from the impurities more thoroughly.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a jujube picker for separating sundries step by step. Background technique [0002] At present, the planting area of ​​red jujube trees is about 8 million mu. The harvest of red dates is mainly done by beating the branches to make the fruits fall to the ground, and then manually picking them up. However, this method has the defects of high manual labor intensity and low picking efficiency, which leads to a corresponding reduction in the economic benefits of fruit growers. [0003] In order to solve the above technical problems, the following technologies have been proposed in the prior art: [0004] Disclosed a kind of air-suction type jujube picking machine as Chinese patent number " 201020641282.0 ", and its open date is on June 22, 2011, and its technical scheme is that described picking machine comprises the frame and blower fan that walking wheel is housed, on machine A fruit box...

AI Technical Summary

Problems solved by technology

Although the fruit box is connected with a grass-blade settling chamber and a lower plate for filtering soil is installed in the box, but because the fruit box is an open structure, and the air velocity at the front end of the fruit box is relatively high, not only the Driven by the airflow, part of the soil will pass over the lower plate and fall directly into the fruit box, and some grass leaves will enter the fruit box along with the jujubes, resulting in the inability to effectively separate the soil and grass leaves from the jujubes. , affecting the picking quality of jujube
