一种水果采摘装置

Abstract

一种水果采摘装置，包括采摘杆、采摘器和绳索机构，采摘器与采摘杆相连，绳索机构沿采摘杆布置与采摘器相连，采摘器包括旋切机构和支撑环，绳索机构牵拉旋切机构沿支撑环作圆弧运动，切削水果果柄。本实用新型水果采摘装置，通过钢丝绳牵拉，驱动采摘器的两组相互垂直的刀片运动形成扇面刀路，适用于斜向生长的水果采摘。相对于传统人工采摘方式，本实用新型在相对安全的工作面上远距离作业，具有安全可靠、省工省力的优势；相对于现有齿梳式采摘器，本实用新型依靠刀片旋切果柄，避免拽拉水果时树枝弹飞果实，操作简便，果实完整率高。

Claims

The axis of the picking rod passes through the center of the support ring. The rotary cutting mechanism includes a sliding bracket and a rotary arm; The sliding bracket is provided with a top pin at the top, which is perpendicular to the support ring. The sliding bracket is provided with a vertical first blade in the middle. The bottom of the sliding bracket is inserted into the arc groove of the support ring and can slide along the arc groove. The plane of the vertical first blade of the rotary cutting mechanism is perpendicular to the plane of the support ring and tangent to the outer surface arc of the support ring. The rotary arm is arranged parallel to the plane of the support ring. The rotary arm is provided with a horizontal first blade. The rotary arm is in the shape of a broken line. One end of the rotary arm is an oblong hole and the other end is a round hole. One end of the rotary arm is slidably connected to the top pin of the sliding bracket through the oblong hole. The other end of the rotary arm is hinged to the support ring through the round hole. The rotary arm can swing around the hinge point in a plane parallel to the support ring. The harvester tilts upwards to cover the fruit, and the rope mechanism pulls the rotary cutting mechanism to move in an arc along the support ring, causing the vertical first blade of the sliding bracket and the horizontal first blade on the rotary arm to move together to form a fan-shaped cutting path to cut the fruit stem.

2. The fruit picking apparatus of claim 1, wherein: The support ring is equipped with a scissor support, a blocking support, and a vertical blade support. All three are of the same height, are narrow and long, and are perpendicular to the plane of the support ring. The number of blocking supports is 6, divided into two groups, and symmetrically distributed with respect to the axis of the picking pole. The scissor lift support is located at the junction of the support ring and the picking rod, and the vertical blade support is located at the end point of the sliding bracket sliding along the arc groove; The vertical blade support is provided with a vertical second blade, the plane of which is perpendicular to the plane of the support ring and tangent to the outer surface arc of the support ring; The outer arc surface of the support ring is also provided with a wire rope limiting seat.

3. The fruit picking apparatus of claim 2, wherein: The support ring is also provided with a spring fixing seat.

4. The fruit picking apparatus of claim 1, wherein: The sliding bracket of the rotary cutting mechanism includes two mutually perpendicular plates, one vertical and one horizontal. The vertical plate of the sliding bracket is perpendicular to the plane of the support ring, and the top pin is fixed to the top of the vertical plate. The horizontal plate of the sliding bracket is parallel to the plane of the support ring, and the thickness of the horizontal plate is the same as the width of the arc groove. The horizontal plate is inserted into the arc groove and slidably connected to the arc groove.

5. The fruit picking apparatus of claim 4, wherein: The horizontal plate is symmetrically provided with six rollers on its center side. Two rollers on the horizontal plate located outside the support ring are in contact with the outer arc surface of the support ring, and four rollers on the horizontal plate located inside the support ring are in contact with the inner arc surface of the support ring.

6. The fruit picking apparatus of claim 2, wherein: A fixed arm is provided between the scissor support and the vertical blade support. A horizontal second blade is provided on the fixed arm. The plane of the horizontal second blade is parallel to the plane of the support ring. The cutting edges of the horizontal second blade of the fixed arm and the horizontal first blade of the rotating arm are arranged facing each other.

7. The fruit picking apparatus of claim 3, wherein: The harvester also includes a spring, which is disposed between the rotary cutting mechanism and the spring fixing seat.

8. The fruit picking apparatus of claim 2, wherein: The harvesting pole is a multi-section telescopic pole, and the telescopic pole is equipped with a wire rope fixing seat.

9. The fruit picking apparatus of claim 8, wherein: The rope mechanism includes an operating handle and a steel wire rope. The operating handle has a V-shaped structure, and the apex of the V-shaped structure of the operating handle is hinged to the picking rod. One end of the steel wire rope is fixed to the V-shaped open end of the operating handle, and the other end of the steel wire rope passes through the steel wire rope fixing seat on the picking rod and the steel wire rope limiting seat on the picker and is fixed to the sliding bracket of the rotary cutting mechanism.

10. The fruit picking apparatus of claim 1, wherein: The harvester also includes a net bag, which is located below the support ring.
