Background technology
Young fruit bagging be mainly prevent fruit from being attacked by birds in growth course, the harm of disease pest and wind
The damage of rain sunlight, can also be effectively isolated the erosion to fruit for the environmental pollution simultaneously after fruit bag, prevent fruit from growing
By branch scratch in journey.Bagging can produce local greenhouse effect, make the suitable humidity of fruit holding, temperature, improve the sweet of fruit
Degree, improves the gloss of fruit, increases fruited yield, and shortens its growth stage.Simultaneously because being not required to during growth apply
Pesticide, makes fruit have high-quality and nuisanceless, meets international standards.
Gather because fruit-bearing forest environment is intricate, fruit tree branch is irregular, so all the time, orchard worker is when to fruit bag
All mainly adopt traditional-handwork bagging.Traditional-handwork bagging is wasted time and energy, inefficiency, and bagging quality differs.In order to carry
High bagging efficiency, it is ensured that bagging quality, mitigates the labor intensity of artificial bagging, market occurs in that packing machine.But existing bagging
The fork plate device design of machine is unreasonable, is easy to young fruit fruit stem fractures, and then has had a strong impact on fruit product during bagging
Amount and bagging efficiency;And existing young fruit packing machine generally requires and is manually pressed together, bagging less efficient it is impossible to meet the bagging in orchard
Demand.

Specific embodiment
Referring to Fig. 1-3, the bag mouth on a kind of young fruit packing machine opens and fold mechanism, and it includes folding bearing 4, described folding
Folded bearing 4 is arranged on the crossbeam 3 of packing machine frame 2 front end, described crossbeam 3 is provided with driving described folding bearing 4 and rises
Or the driving means 5 declining, described folding bearing 4 is provided with guide post 401, described guide post 401 is arranged with spring
402, described folding bearing 4 is provided with the through hole ejecting upwards for described guide post 401, the lower end of described guide post 401 is solid
Surely it is connected with Magnet mounting seat 403, the lower end of described spring 402 is against in described Magnet mounting seat 403, described spring 402
Upper end is against on described folding bearing 4;Magnetic for adsorbing bagging upper side iron wire is provided with described Magnet mounting seat 403
Ferrum, the both sides of described Magnet mounting seat 403 have been respectively articulated with side guide 404, the upper end of described side guide 404 and connecting rod 405
Lower end is hinged, and the upper end of described connecting rod 405 is hinged on folding bearing 4, and the both sides of described guide post 401 are respectively arranged with one
Described side guide 404 and described connecting rod 405;Described in driving two when the relatively described Magnet mounting seat 403 of described connecting rod 405 pushes
In the middle of side guide 404 is lateral from two, extruding will be will cover bag mouth closure;The front end of described frame 2 is located at described Magnet mounting seat 403
Underface be provided with upwardly extending folded sheet 5, described folded sheet 5 and described side guide 404 each along bagging bag mouth
Width is arranged.Described folded sheet 5 is L-type plate, and the horizontal plate face of described folded sheet 5 is fixed by screws in described packing machine
In the fork plate 406 of front end, the vertical plate face of described folded sheet 409 midline position just to described Magnet mounting seat 403.
In the present embodiment, described driving means 5 are turn drive motor, and the outfan of described turn drive motor is arranged straight down,
The outfan end of described turn drive motor is connected with leading screw 407, and the described two ends folding bearing 4 are connected on described leading screw 407
Nut 408 on, rotate forward or backwards during described turn drive motor described folding bearing 4 rise or fall.
In the present embodiment, the described two ends folding bearing 4 are respectively arranged with a described turn drive motor and described leading screw
407, described turn drive motor is fixedly installed on described crossbeam, to ensure to fold the driving force on bearing both sides when rising or falling
Degree is equal, and then improves job stability.
