Description

Technical Field

[0001] The invention relates to a fruit picking device. Background Art

[0002] When the existing fruit picking device is used to pick fruits, in order to prevent the fruits from falling from a high altitude and being damaged, the fruit frame generally needs to be placed at a high place, which is troublesome. At the same time, frequently picking fruits with force also makes people easily tired. Summary of the invention

[0003] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a fruit picking device, which does not require the fruit frame to be placed at a high place when picking fruits, and can use the gravity potential energy of the fruits to assist in cutting.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: the designed fruit picker includes a fixed handle, a movable handle, a gear, a main rod, a secondary rod, a wire rope, a fixed blade, a movable blade, a return spring, a knife seat, a welding piece, a rack, a guide tube, a base, an interface, a buffer seat, a buffer spring, a fixed shaft, a one-way clutch, a right toothed disk, a connecting block, a left toothed disk, an impact rod, a cylindrical cam, a rotating shaft, and a sleeve. The knife seat is installed at the top of the secondary rod, the fixed blade is fixedly connected to the knife seat, the movable blade is hinged to the knife seat, the two ends of the return spring are respectively connected to the movable blade and the knife seat, the fixed handle is fixedly connected to the top of the main rod, the sleeve is installed on the upper part of the fixed handle, the rotating shaft is installed in the hole of the sleeve and rotates with it, the cylindrical cam is made into one piece with the rotating shaft, the movable handle is mounted on the rotating shaft through a key sleeve, and one end of the wire rope is connected to the movable The lower part of the blade has the other end connected to the upper part of the movable handle. The upper end of the conduit is provided with a bell mouth. The lateral opening at the lower part of the conduit is welded with the interface. The conduit is connected to the main rod through a welding sheet. The buffer seat is installed at the lower part of the conduit and slides with it. The base is installed at the bottom of the conduit through bolts. The buffer spring is installed between the buffer seat and the base. A vertical groove is opened on the right side of the conduit so that the rack and the buffer seat can be fixedly connected through a connecting block. The fixed shaft is fixedly installed on the main rod. The left toothed disk is assembled on the left part of the fixed shaft through a sliding spline. A protrusion is formed on the outer column of the left toothed disk, and the protrusion extends into the groove on the outer column of the cylindrical cam. The right toothed disk is mounted on the right part of the fixed shaft and rotates with it. The inner ring of the one-way clutch is tightly connected to the right toothed disk, the outer ring of the one-way clutch is tightly connected to the gear, the gear is meshed with the rack, and the impact rod is fixedly installed on the left side of the gear.

[0005] The fastening connection between the inner ring of the one-way clutch and the right toothed disc described in the technical solution may be an interference fit connection between the inner ring of the one-way clutch and the outer column of the right toothed disc.

[0006] The fastening connection between the outer ring of the one-way clutch and the gear described in the technical solution may be an interference fit connection between the outer ring of the one-way clutch and the inner hole of the gear.

[0007] The working principle of the present invention is that the cut fruit enters the conduit through the trumpet mouth at the upper end of the conduit and then impacts the buffer seat. Due to the action of the buffer spring, the speed of the fruit is gradually reduced, thereby ensuring the integrity of the fruit. When the buffer seat is completely below the interface, the fruit is collected into the fruit basket from the interface. In this process, the one-way clutch does not play a restrictive role. At the same time, the rack drives the gear to rotate following the downward movement of the buffer seat. Once the fruit stem is cut off, we will release the movable handle. At this time, under the action of the return spring, the movable handle opens around its hinge fulcrum, so that the right toothed disc and the left toothed disc are engaged through the key, the rotating shaft and the cylindrical cam. Then, the process of the buffer seat moving downward ends. Due to the action of the one-way clutch, the gear cannot be reversed and the buffer seat cannot move upward, so that the elastic potential energy converted from the gravitational potential energy of the fruit is stored. When cutting and picking next time, pinch the movable handle, the right toothed disc and the left toothed disc are separated, and the right toothed disc, the one-way clutch as a whole and the gear can rotate in the opposite direction. In this way, the elastic potential energy will be converted into the kinetic energy of the buffer seat, the gear, the one-way clutch and the right toothed disc. When the fixed blade and the movable blade are closed, the impact rod impacts the movable handle to assist cutting. It should be noted that since the impact rod is fixedly installed on the side of the gear, the rotation angle is limited. When designing specifically, comprehensive consideration of various parameters will achieve the best effect.

[0008] The beneficial effects of the present invention are that when picking fruits, it is not necessary to place the fruit frame at a high place, and the gravity potential energy of the fruits can be used to assist in picking. BRIEF DESCRIPTION OF THE DRAWINGS
