Description

Technical Field

[0001] The utility model relates to the technical field of cutting saws, in particular to a device for harvesting branches of thin-shelled pecan trees that are damaged by pests and diseases. Background Art

[0002] The thin-shelled hickory tree has a straight trunk and a broad, ovate crown. Its well-developed root system makes it resistant to waterlogging and humidity. It can be planted singly or in clusters near lakes and lawns, making it a suitable shade tree for gardens, streetscapes, and afforestation along rivers and in plains. It is an excellent tree for both urban and rural landscaping and for fruit production. Its fruit can be eaten fresh, pressed for oil, or used in solid beverages. Its tough texture makes it an excellent military timber. The seed kernel contains over 70% oil.

[0003] As the age of the thin-shelled pecan tree increases, the gaps between branches become smaller, the density of the forest increases, the ventilation and light transmission become worse, and the tree body needs to grow nutrient branches and balance the development of fruits, which makes it easy to get pests and diseases. If the branches and fruits of the orchard are damaged by pests and diseases and are not cleared out of the orchard in time, they will continue to affect the tree body, which will have a serious adverse effect on the growth of fruit trees and the high yield of fruit. Therefore, the prevention and control of pests and diseases has become the focus of orchard tending and management. For the damaged branches, they can be collected and cleaned in a centralized manner, such as using a device to process such branches. However, most of the existing branch cutting devices have a limited scope of use. For example, the utility model with the announcement number CN213306383U can cut branches at high altitudes, but it does not have a branch clamping device. This will result in the cutting device being unable to cut the branches continuously and effectively due to insufficient stability of the device. Not only is the efficiency low, but it is also easy for the device to tilt due to the influence of the cutting device. Furthermore, the device has a limited cutting height and a limited length of connecting rods, so it cannot cut higher branches. The optimization of the present invention not only effectively solves the existing problems in branch cutting, but also adds a branch collection trough to collect harmful branches and fruits on them that have not fallen due to pests and diseases, and then burn or bury them. Utility Model Content

[0013] The utility model realizes the purpose of stabilizing the device and collecting branches during the cutting process through the first motor, gears, turntable, second motor, rocker arm, third hydraulic telescopic rod, collection trough and clamping claws, which not only greatly reduces the shaking of the device during the cutting process, but also avoids the situation where branches suddenly fall and hit the user at the moment of cutting. The cut branches and the fruits on them will automatically fall into the collection trough, omitting the step of later processing of the branches. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Working principle: Before using the device, first control the first hydraulic telescopic rod 14 to extend, and drive the second telescopic arm 17 to move through several connecting blocks 12. When the second telescopic arm 17 moves, the third telescopic arm 11 and the second hydraulic telescopic rod 16 are driven to move through the first base plate 19. When the first hydraulic telescopic rod 14 is extended to the right position, control the second hydraulic telescopic rod 16 to extend, and the second hydraulic telescopic rod 16 drives the third telescopic arm 11 to move. When the third telescopic arm 11 moves, the slot 21 on its side provides moving space for the fixed connecting block 12. The end of the third telescopic arm 11 pushes the second mounting plate 5 to move until the cutting device is raised to the required height or the second hydraulic telescopic rod 16 can no longer be extended. Then the fourth hydraulic telescopic rod 4 can be controlled to adjust the inclination angle of the first telescopic arm 7.

[0030] When the height and tilt angle of the device are adjusted to the required height, the first motor 24 is started to drive the gear 23 to rotate, and the gear 23 drives the turntable 26 to rotate, and the rocker arm 27 is adjusted to the left and right directions. After reaching the required angle, the second motor 30 is started to drive the rocker arm 27 to swing up and down until the required angle is reached, and then the third hydraulic telescopic push clamp 29 is started to clamp the branch, and finally the cutting saw body 6 can be started to cut the branch. After the cutting is completed, the branches (with damaged fruits that have not fallen) will automatically fall into the collection trough located on the mobile device (the size of the collection trough can be determined according to actual conditions) to collect the cut branches.

[0031] It is worth noting that the entire device is controlled by a master control device. Since the devices matched with the control device are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.
