Push-rocking type Chinese date classifying harvester

Abstract

The invention provides a push-rockable Chinese date classifying harvester which is characterized by comprising a frame with travelling wheels, an eccentric wheel mounted on the frame, a funnel-shaped collecting device, a classifying screen, and a push-rocking device. The push-rocking device comprises a multi-bar connector, a horizontal pull bar, an upper pull bar, a lower pull bar, and a clamp, wherein the horizontal pull bar, the upper pull bar and the lower pull bar are hinged to the multi-bar connector, the clamp is mounted at the top of the upper pull bar and comprises an upper clamping plate, a lower clamping plate, a support bar, a sleeve, and a lock nut, both the sleeve and the lock nut are sleeved on the support bar in a threaded manner, the lock nut is abutted to the bottom of the sleeve, the bottom of the support bar is fixed at the top of the upper pull bar, and the upper clamping plate and the lower clamping plate are correspondingly and horizontally fixed at the top ends of the support bar and the sleeve. The other end of the horizontal pull bar is hinged to the eccentric wheel. The other end of the lower pull bar is connected with the frame through a pin. The collecting device is connected below the clamp, and a flexible pipe is disposed at the bottom of the collecting device. The classifying screen is connected to an outlet of the flexible pipe. The push-rockable Chinese date classifying harvester is high in harvesting efficiency, low in damage to fruits and low in labor intensity.

Description

technical field [0001] The invention relates to a push-type jujube harvesting device with a grading function, which belongs to the technical field of agricultural machinery. Background technique [0002] As a delicious and popular fruit, jujube has the characteristics of tight time and heavy tasks. Currently, the commonly used harvesting methods are manual picking or bamboo pole tapping, which not only leads to high labor intensity and long harvesting time, but also due to Knocking often leads to the decline of jujube quality and commodity performance; compared with the existing 200910220762.1, the device uses air suction to pick fruit, although it does not damage the fruit, but the efficiency is low, and it is not suitable for jujube harvesting; among them, jujube is graded Generally set up special-purpose equipment in addition, and this device is compared with it, adopts squirrel-cage type grading device as 200720100783, mainly completes jujube grading by changing the gap ...

[0002] As a delicious and popular fruit, jujube has the characteristics of tight time and heavy tasks. Currently, the commonly used harvesting methods are manual picking or bamboo pole tapping, which not only leads to high labor intensity and long harvesting time, but also due to Knocking often leads to the decline of jujube quality and commodity performance; compared with the existing 200910220762.1, the device uses air suction to pick fruit, although it does not damage the fruit, but the efficiency is low, and it is not suitable for jujube harvesting; among them, jujube is graded Generally set up special-purpose equipment in addition, and this device is compared with it, adopts squirrel-cage type grading device as 200720100783, mainly completes jujube grading by changing the gap between the sieve bars, and this device has obvious differences; so in the current regional economic development Under the current conditions, many jujube planting areas urgently need a mechanized and mobile jujube harvesting and grading joint operation device to improve operation efficiency, reduce harvest damage of jujube, and reduce operating costs
