Auxiliary manual picking machine for fruits growing on trees based on crank sliding block motion

Abstract

The invention discloses an auxiliary manual picking machine for fruits growing on trees based on crank sliding block motion. The machine comprises a hollow rod, a crank sliding block mechanism is arranged on the hollow rod, and a rack is arranged on the portion, at the internally-tangent top of the hollow rod, of a sliding block of the crank sliding block mechanism; a rotation handle is arranged on a crank of the crank sliding block mechanism, a pair of gears meshed with each other are arranged at the top of the hollow rod, and one gear is meshed with a rack simultaneously; arc blades are fixed to gear shafts of the two gears respectively, knife edges of the arc blades are opposite, and the arc blades simultaneously swing back and forth along with the corresponding gears to achieve occlusion cutting; a fruit collection cylinder with a buffer function is arranged below the arc blades. According to the auxiliary manual picking machine, through position and parameter design of the gears and the rack, in the process that the crank continuously rotates, the blades can conduct constant-speed circular motion to achieve circular cutting; through design of a buffer structure of the collection cylinder, the fruits are prevented from being damaged after being hit in the picking process. The auxiliary manual picking machine accords with the man-machine engineering design idea and has highpracticability.

Description

technical field [0001] The invention belongs to the field of mechanical structures, and relates to an agricultural machine, in particular to an auxiliary artificial harvesting machine for tree fruits based on the movement of a crank slider. Background technique [0002] In order to realize the cutting of fruit stems, the existing auxiliary picking mechanism adopts geometric design according to the corresponding actual needs, makes corresponding pruning shears, and saws off the fruit stems through the sawtooth on the cutting blade surface, but in the actual application process because of Due to thick fruit stems, slippery skin, and insufficient hardness of the material used for the blade surface, some fruits with thick fruit stems cannot be effectively cut, and these picking mechanisms generally do not have collection devices. The fruit will not be able to be clamped and freely fall, and the skin will be damaged, which will affect the subsequent storage and transportation. Th...

Problems solved by technology

[0005] In view of the above technical problems, the present invention provides a tree fruit assisted manual picking machine based on the movement of the crank slider. The present invention not only has the functions of the conventional tree fruit assisted picking machine, but also more effectively realizes tree fruit picking activities. , at the same time, it solves the problem of the wear of the fruit stem on the cutting tool and the collection of fruits, and solves the defect that it is difficult for conventional auxiliary picking machines to collect and transport fruits
