A protective device for collecting coniferous tree seeds with the function of removing impurities

Abstract

The invention discloses a coniferous tree seed collection protection device with the function of removing impurities, and relates to the technical field of separation of collected seeds and impurities in the harvesting process of coniferous pine cones and the personal protection of harvesters, including being set in a The support frame in the middle of the main trunk of the coniferous tree, the seed collector located below the support frame and the seed receiving cover installed above the support frame solve the safety problems of the conifer pine cone harvesters and the difficulty in planting. For the problem of carrying and collecting, the present invention adopts an inflatable cushion with a groove and a seed collector with a spring device and a vibrating device, which effectively reduces the damage received by the harvester after accidentally falling, and effectively prevents the fall from falling. Collect the pine cones to prevent loss and separate the impurities that fall into the seed collection box.

Description

technical field [0001] The invention relates to the technical field of separation of harvested seeds and impurities during the harvesting process of conifer pine cones and personal protection of harvesters. Background technique [0002] At present, in most seed orchards in the forest regions of Northeast my country, the collection of coniferous seeds is mainly based on manual climbing and pine cones. The 30-year-old Pinus sylvestris sylvestris forest in the Xiaoxing’anling area is an example. The average tree height is 16m, the average diameter at breast height is 17cm, and the average height under the branches is 7.7m; while the mature forest of Korean pine can reach 50m in height and 1m in diameter at breast height. Moreover, coniferous trees are basically cross-pollinated, and the female flowers are mostly distributed in the middle and upper parts of the tree body. Therefore, as the age of the tree increases, the growth position of the pine cone increases, and the work of ...

AI Technical Summary

Problems solved by technology

Moreover, coniferous trees are basically cross-pollinated, and the female flowers are mostly distributed in the middle and upper parts of the tree. Therefore, as the age of the tree increases, the growth position of the pine cone increases, and the work of seed collection becomes more difficult.

In addition, there are many dead branches and peeling bark in the lower part of the trees that have not been thinned. In the process of manual climbing, there are often problems such as stepping on air and slipping, which will cause the danger of people slipping. In addition, mining tower operations are mostly in the trees The upper part is carried out, and the risk of falling is extremely high. In the northeast forest area, there are incidents of casualties caused by harvesting pine cones every year.

[0003] In addition, in the existing process of climbing trees and picking towers, tree climbers either put the collected seeds in net pockets or back baskets, or knock down the pine cones and then go down the tree to pick them up. The increase in the collection of seeds and the increase in the load make it more difficult for the harvesters to move during the climbing process. The latter often causes the loss of seeds in the process of descending the tree to find the tower, and the workload in actual operation is relatively large.
