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 c

Embodiment 1

[0025] see figure 1 , figure 2 In the caragana seed harvester shown, the outer circumference of the rotating shaft 1 that mainly transmits power has three protrusions extending along the axis direction, which are shaped like flat keys; A groove shaped like a keyway, the two cooperate to transmit torque, and three comb teeth 3 are fixed on the outer surface of the comb holder 2 to form a collector. The comb holder 2 can slide along the axis direction along the surface of the rotating shaft 1, and the gap between the comb teeth 3 along the axis direction can be set by adjusting the washer. The lengths of the combs in the collector assemblies with serial numbers 4, 5, and 6 increase successively, and the angles of their combs in the circumferential direction of the rotating shaft differ by 40°, that is, 360° / (3×3); the rotating shaft 1 The two ends of the motor are rotatably supported on the frame, and are connected with the output shaft of the motor 10 through a coupling 9 . ...

Embodiment 2

[0031] Figure 6 The difference between shown embodiment 2 and embodiment 1 is: the conveying mode that fruit pod is transported in the storage box adopts screw conveyor and blower fan 23 to be respectively responsible for the horizontal conveying of fruit pod and seed and vertical promotion, wherein The screw conveyor consists of a shaft 21 with a helical surface, a semicircular bottom plate 22 and bearings 20 at both ends, and its driving device is composed of a motor 10 and a shaft coupling 9 .

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...
