3. The picking machine according to claim 1, characterized in that the fixed pulley and steel cable telescoping device is composed of a fixed rod, a moving rod, a fixed pulley and steel cables, wherein 4 steel cables are started from a support at the bottom of a driven rod, pass through the fixed pulley and then are tied to a rotating shaft connected with the motor, the bottom of the driven rod is directly tied to the rotating shaft connected with the motor, and the steel cables are pulled to drive the moving rod to telescope when the motor rotates forwards and backwards, so that the telescoping of the three-jaw rotary picking hand is realized.

Technical Field

The invention belongs to the field of agricultural machinery.

Background

The telescopic coconut picking machine is efficient coconut picking equipment. Still adopt artifical picking at present coconut picking, the picking process is not only wasted time and energy, but also is accompanied by the danger of falling.

Disclosure of Invention

The invention aims to change the picking mode of the coconut, improve the picking efficiency of the coconut and ensure that a coconut picking worker can complete work safely and efficiently.

The technical scheme of the invention is realized as follows:

comprises a three-jaw rotary picking hand, a fixed pulley and steel cable telescopic device, a stepping motor, a mobile platform, a truck and the like. Three claws evenly distributed for 360 degrees are arranged on the three-claw rotary picking hand, the three claws are connected to the same magnetic plate by connecting rods, the magnetic plate can move up and down under the combined action of spring force and coil repulsion force to finish the actions of grasping and loosening coconuts, and the coconuts are rotated for more than 360 degrees under the action of the sliding ring to twist off the handles of the coconuts. The fixed rod and the moving rod of the telescopic device are respectively provided with a fixed pulley and a steel cable, 4 steel cables on the moving rod penetrate through the fixed pulley on the fixed rod and then are tied to a rotating shaft connected with the motor, the other 4 steel cables are directly connected with the rotating shaft, and the steel cable is pulled to drive the moving rod to stretch when the motor rotates forwards and backwards. After picking, the coconuts are slid into the truck behind the moving platform along the pipeline between the three-jaw rotary picking hand and the fixed pulley steel cable telescopic device.

Compared with the prior coconut picking equipment, the coconut picking device has the advantages that picking hands are redesigned, a saw blade or a clamp is not used for picking the coconuts, in addition, the telescopic mechanism adopts the steel cable and the fixed pulley for telescopic movement, a space of a conveying pipeline is also made up in the telescopic device, and the picking and collecting integration can be realized. By adopting the structure of the invention, not only can the safety of coconut picking workers be ensured, but also the coconut picking efficiency of coconut farmers is improved to a certain extent.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the invention comprises a three-jaw rotary picking hand, a fixed pulley steel cable expansion device, a mobile platform and a truck. When the coconut picking machine is ready for work, the moving platform 5 moves to the vicinity of a coconut tree, then the electric push rod 7 pushes the fixed rod 8 of the telescopic device to lift, the motor in the moving platform rotates positively to pull the steel cable 10 passing through the fixed pulley 9 so as to extend the moving rod 11, then the motor 13 rotates to adjust the angle of the three-jaw rotating picking hand 14 to align the coconut, the coil 21 is powered off, at the moment, the magnetic plate 19 is only subjected to downward elastic force of one spring along the axis, the magnetic plate moves downwards, the connecting rod 16 drives the jaws 15 to fold inwards to clamp the coconut, the upper part and the lower part of the picking hand are connected through the framework 24, the shaft shoulder of the framework 24 is contacted with the rotating shell 29 at the lower part of the picking hand through the rollers 26 strung on the rotating shaft 25, and the rollers are respectively arranged in 6 rows on each surface of the upper surface and the lower surface of the shaft shoulder, and the number of the rollers is 3 in each row and 36 in total. After clamping the coconuts, the slip ring 27 drives the upper part of the picking hand to rotate to twist off the coconuts, the coil 21 is electrified after the coconuts are twisted off, the magnetic plate moves upwards (the repulsive force is larger than the elastic force of the spring) under the action of the upward repulsive force of the coil along the axis, the connecting rod 16 drives the claw 15 to open outwards, the coconuts fall into the pipeline 23, and finally reach the truck 1 after sequentially passing through the three-grab rotating picking hand 14, the hose 12, the moving rod 11, the fixed rod 8 and the hose 3.

The device comprises a truck 1, a pin 2, a hose 3, a shaft 4, a movable horizontal adding part 1 and a movable horizontal adding part 5, a telescopic device 6 base, an electric push rod 7, a telescopic fixed rod 9, a fixed pulley 10, a steel cable 11, a telescopic movable rod 12, a hose 13, a stepping motor 14, a three-jaw rotary picking hand 15, a jaw 16, a connecting rod 17 base, a spring 18, a magnetic plate 19, a jaw 20 shell, a coil 21, a jaw 22 tail plate 23, a pipeline 24, a framework 25, a roller rotating shaft 26, a slide ring 27, a slide ring 28 and a rotary shell 29.
