Blueberry picking and sorting apparatus and working method

Abstract

The invention relates to a blueberry picking and sorting apparatus and a working method, and belongs to the technical field of planting machinery and equipment. The blueberry picking and sorting apparatus and the working method are in particular applicable to picking and preliminary sorting of dwarf blueberries in mountains. The apparatus includes a bottom frame and a machine frame arranged on thebottom frame. The machine frame is equipped with a picking device and a sorting device. The picking device is used for picking fruits. A collection bin is arranged on the bottom frame. The picked fruits are placed in the collection bin, and then sent to the sorting device by a conveyor belt for multi-level sorting. With the apparatus of the invention, the efficiency of blueberry picking operationcan be improved, the artificial labor intensity can be reduced, and multiple damage to blueberry vines can be reduced.

Description

technical field [0001] The invention relates to a blueberry picking and sorting device and a working method, especially suitable for picking and preliminary sorting of low bush blueberries in mountain areas, and belongs to the technical field of planting machinery and equipment. Background technique [0002] Blueberry is a perennial shrub small berry fruit tree, and the low bush blueberry tree is short, usually 30-50cm in height. Blueberry picking is the most time-consuming and labor-intensive link in the entire blueberry industry chain. In particular, wild blueberries in low-clump mountainous areas are difficult to pick mechanically due to the constraints of geographical conditions. Currently, most of the wild blueberries are picked manually. Existing large-scale mechanical picking equipment is mostly designed for artificially planted blueberry production bases, and does not have efficient picking conditions for irregularly distributed mountain low bush blueberries.

Problems solved by technology

In particular, wild blueberries in low-bush mountainous areas are difficult to pick mechanically due to the constraints of geographical conditions. At present, most of them are picked by hand.

Existing large-scale mechanical picking equipment is mostly designed for artificially planted blueberry production bases, and does not have efficient picking conditions for irregularly distributed mountainous low bush blueberries

The existing low bush picking equipment is not perfect in fruit sorting and collection, and the degree of integration of picking and sorting machinery is not high.

[0003] Chinese patent document (Application No. 201620674152.4) discloses a device for picking blueberries in low bushes in mountainous areas to separate blueberries from sundries. It only screens out sundries such as branches and leaves falling with the fruit, and cannot target blueberry fruit diameters. fine sieving

And in the actual application process, the blueberries that fell in the early stage will block the filter screen, and the actual filtering effect on debris is not obvious; due to the poor ventilation conditions in the blueberry bushes and the limited wind power of the blower mechanism, it is difficult for this device to remove heavy debris. For wild blueberry clusters with different sizes and irregular shapes, the U-shaped clips and slots cannot ensure that all the branches under the action of the vibration mechanism are gathered into the top of the conical bucket during the picking process, and a large number of fruits will fall. Serious waste and low actual efficiency

[0004] Chinese patent document (Application No. 201620910860.3) discloses a blueberry picking device, which uses a walking robot to replace labor. The spatial position movement of this solution through the linear displacement device is based on the area of ​​its support platform 1, and the working space is limited. ; It is necessary to regulate the posture of the picking device 6 by means of the robot body structure 4 and send it to the blueberry clump

This will inevitably require multiple drive motors or air motors to be installed at the joints, which makes the structure of actuator pose control too complex, expensive, limited working space, and poor in effect of pose control

In addition, during the actual operation of the device, the mechanical arm needs to extend out of the support platform as much as possible, and the multi-joint drive arm has a large mass due to the large number of drives, which makes the center of gravity of the whole device seriously deviated and the stability is poor

In the actual picking operation, it is necessary to first bend the blueberry branches to the collecting device 7. In the process, a large amount of blueberries will fall and cause a lot of waste, and due to the limitations of the arrangement of the collecting device and the picking device, it is easier for the device to realize shallow cleaning of the blueberry bushes. It is more difficult to pick the fruit of the inner layer than the fruit of the inner layer
