Harvesting machine for caragana microphylla seeds

Abstract

The present invention relates to a machine for harvesting desert shrubs and caragana microphylla seeds / pods. The machine realizes a mechanization harvesting operation of the caragana microphylla seeds and pods, the operation efficiency of the machine is more than 10 times of that of manual work, the timely harvesting problem of the caragana microphylla seeds is solved, powerful support is provided for resource development and utilization of caragana microphylla seeds, and the machine is expected to generate significant economic and social benefits. The harvesting machine for caragana microphylla seeds of the present invention mainly comprises a rack, a harvesting device, a rotating shaft, a driving mechanism and a transport device. The harvesting device is rotatably supported on the rack, and is composed of a plurality of comb teeth uniformly arranged on the rotating shaft in radial and axial directions, gaps between adjacent comb teeth in the axial direction of the shaft are adjustable, and the gaps are successively separated from each other in a certain angle in the circumferential direction of the rotating shaft. The harvesting device is driven by a motor or other power sources. The transport device positioned below the harvesting device can transport the harvested caragana microphylla seeds / pods into a storage tank.

Description

Technical field: [0001] The technology relates to a Caragana seed harvester for harvesting Caragana seeds. Background technique: [0002] Caragana is a sandy shrub with extremely developed root system. Caragana has strong adaptability and high survival rate. It is an excellent tree species for windbreak, sand fixation and water and soil conservation in the central and western regions. Caragana seeds are rich in oil, nitrogen and nutrients. Caragana branches and leaves are good firewood, oil refining raw materials and forage feed. But the planting of caragana, stubble and rejuvenation, and the development of economic value are still at a relatively low level. The industrial chain is short, the added value is low, and the enthusiasm of farmers and herdsmen is not high. The timely harvesting of Caragana seeds and the development of the application value of the whole plant will greatly improve the above situation, and will play an important role in promoting the expansion of...

AI Technical Summary

Problems solved by technology

At present, Caragana seeds are mainly picked manually, which not only consumes a lot of manpower and material resources, but also causes the pods of Caragana pods to crack naturally due to untimely harvesting, and the seeds are scattered on the sand, which can no longer be picked up, resulting in a lot of waste

Therefore, it has become very urgent to improve the mechanized harvesting efficiency of Caragana seeds, and the improvement of harvesting efficiency means to increase the advancing speed of the machine, and the improvement of the advancing speed of the machine needs to be matched with the comb tooth speed of scraping and combing Caragana branches. Otherwise, the comb teeth will pass by many Caragana branches, without the effect of multiple scraping and combing, it is likely that the recovery rate will be greatly reduced; and the increase in the speed of the comb teeth may reduce the number of Caragana branches. Therefore, in order to ensure both the harvesting efficiency and the recovery rate, enough comb teeth must be arranged on the rotating shaft in the same direction as the machine, and within the time the rotating shaft rotates for one revolution, that is There must also be enough batches of comb teeth in the circumferential direction of the rotating shaft to scrape and comb the branches of Caragana fragrans, and the fruit pods, seeds and young leaves collected quickly also need to be collected in time and transported to the storage box. Therefore need to develop high-efficiency caragana seed harvester
