Description

Technical Field

[0001] The invention relates to a bush guiding device for harvesting small berries in the field of agricultural machinery, in particular to a bush guiding device for vibrating harvesting of blueberries. Background Art

[0002] Small berries like blueberries, currants, sea buckthorn, blue indigo, and blackberry have a shrub-like appearance, with a main trunk divided into main branches, which in turn have lateral branches, and these branches in turn have secondary branches. The trees vary significantly in size and shape, and branches are the primary components of the tree's morphological structure. During vibratory mechanical harvesting, the vibrating harvesting device acts on the shrub branches, periodically and continuously hitting the plant. The inertial force generated by the vibration separates the ripe fruit from the main branch. Due to the alternating branches and leaves of shrubs and their complex growth structure, existing vibratory harvesting machines are prone to tangling and knotting the branches as the vibrating mechanism advances, resulting in damage to the branches during operation. Furthermore, the center and outermost branches of the shrub cannot fully enter the operating range of the vibration system, all of which directly affect the berry harvesting effect and severely affect the efficiency of mechanical harvesting. Summary of the Invention

[0003] The purpose of the present invention is to address the above-mentioned problems and provide a shrub guiding device for a shrub-type small berry vibration harvesting machine. The device can realize the orderly feeding of bushes, avoid the entanglement and knotting of bush branches during the advancement of the machine, reduce the damage to the bush branches, and facilitate guiding the branches in the center and outside of the bush into the operating range of the vibration system, thereby improving the harvesting rate.

[0050] Working principle of the present invention:

[0051] As the vibrating harvester advances, shrub branches enter from the front of the guide device. Upper guide rods 3 and lower guide rods 8 constrain the branches' positions. As the harvester advances, the branches gradually enter the vibrating operating area. At the rear of the guide device, the branches are further gathered due to the outward bend of upper guide rod 3 and the semicircular curve of lower guide rod 8. This guide ensures full contact between the branches and the vibrating device, increasing the vibration time and effectively improving the fruit collection rate. The guide device's restraint of the branches prevents entanglement and knotting, effectively reducing damage to the branches caused by the harvester. It also ensures that branches from both the center and the outer edges of the shrub are fed into the vibrating operating area, improving the fruit collection rate.

[0052] Finally, it should be noted that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0053] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
