Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit harvesting technology, and in particular to a fruit harvesting device. Background Technology
[0002] When fruits ripen, appropriate harvesting methods need to be adopted according to the characteristics and maturity of different fruit varieties. For example, walnuts and chestnuts may require tools to knock or shake the branches to make them fall, while apples and pears are usually picked directly by hand. However, for some fruit trees located high up, where personnel cannot reach, other auxiliary tools are often needed. For example, a long pole-shaped harvester is currently used, with a clamp at the end to hold the fruit. This clamp allows for quick and easy harvesting of fruits from high places, but only one fruit can be harvested at a time. The harvested fruit must be put down before the harvester can be inserted again to reach higher places. Another method is to directly set a container at the end of the pole, where the harvested fruit falls directly into the container. Although continuous harvesting is possible, when a large number of fruits accumulate, holding the harvester for a long time can cause soreness in the upper limbs and is physically demanding. Based on the above, a fruit harvesting device needs to be designed to solve these problems. Utility Model Content
[0003] This utility model provides a fruit harvesting device to solve the problems existing in the prior art.
[0004] The technical problem solved by this utility model is achieved by the following technical solution:
[0005] A fruit harvesting device includes a harvesting pole with openings at both ends and a hollow interior for conveying harvested fruit. One end of the harvesting pole is equipped with a clamping harvesting unit, the axis of which coincides with the axis of the harvesting pole, for picking the fruit into the central cavity of the harvesting pole. The clamping harvesting unit includes multiple elastic plates equidistantly arranged around the axis of the harvesting pole and a pulling member on the outer wall of the elastic plates. When the multiple elastic plates are in a free state, they converge toward the axis of the harvesting pole. When the multiple elastic plates are pulled outward by the pulling member, the clamping harvesting unit opens.
[0006] Preferably, the pulling member includes a pull rope disposed on the elastic sheet and a pull plate connected to the other end of the plurality of pull ropes, wherein the pull rope is connected to the end of the elastic sheet away from the picking rod.
[0007] Preferably, the picking pole is provided with a limiting hollow rod parallel to its axis, and the pull rope passes through the limiting hollow rod.
[0008] Preferably, the end of the picking rod away from the clamping picking unit is connected to a corrugated conveying hose.
[0009] Preferably, a flexible protective pad is provided on the inner circumference of the picking rod.
[0010] Preferably, the picking pole is connected to a telescopic handle via a connecting plate, and the telescopic handle is used to pick fruits at different heights.
[0011] The beneficial effects of this utility model are: after the fruit is picked by the clamping and picking unit, it falls directly through the internal cavity of the picking rod, reducing the weight of the end of the picking rod and eliminating the need to frequently pick up and put down the picking rod to retrieve the fruit, making it more convenient and faster and improving the picking efficiency of fruits at high places.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0018] Reference Figures 1-3As shown, a fruit harvesting device includes a harvesting pole 1 with openings at both ends and a hollow interior. The diameter of the hollow interior of the harvesting pole 1 is larger than the diameter of the fruit to be harvested, used for conveying the harvested fruit. A clamping harvesting unit is provided at one end of the harvesting pole 1, and the axis of the clamping harvesting unit coincides with the axis of the harvesting pole 1. After the clamping harvesting unit picks the fruit, the fruit can fall into the middle cavity of the harvesting pole 1 and fall downwards. There is no need for manual picking by lowering the harvesting pole 1 and then lifting it again. The fruit also does not need to be temporarily stored in the container at the end, so as to avoid hand discomfort when picking the fruit due to the large weight of one end of the harvesting pole 1. In order to allow the fruit to fall directly into the interior of the harvesting pole 1, the clamping harvesting unit includes a clamping unit surrounding the axis of the harvesting pole 1. The elastic sheets 2 are arranged circumferentially at equal intervals, and the pulling member 21 is located on the outside of the elastic sheets 2. When the multiple elastic sheets 2 are in a free state, they converge toward the axis of the picking rod 1. When the multiple elastic sheets 2 are pulled outward by the pulling member 21, they can be folded into an approximately trumpet shape to achieve the opening of the picking unit. The elastic sheets 2 can be made of a material with a certain elasticity that can automatically reset under no external force. At this time, the opening end can be aligned with the fruit to be picked. Then, the pulling member 21 is used to release the pull on the elastic sheet 2, so that the elastic sheet 2 resets. After the picking rod 1 is moved backward, the elastic sheet 2 is driven to pick the fruit. The fruit falls directly into the cavity inside the picking rod 1 to realize the fruit transportation. The picking rod 1 does not need to be lowered to complete the transportation of the picked fruit, thus realizing continuous picking.
[0019] Reference Figure 3 As shown, furthermore, in order to avoid damage to the fruit during transportation, a flexible protective pad 5 is provided on the inner circumference of the picking pole 1. The flexible protective pad 5 can be made of flexible materials such as silicone or cotton cloth. When the fruit falls into the interior of the picking pole 1, the buffering effect of the flexible protective pad 5 reduces the damage caused by the fruit rolling down and ensures the picking quality.
[0020] The picking pole 1 is connected to a corrugated conveying hose 4 at one end, which holds the picking unit. Since the other end of the picking pole 1 cannot be directly disconnected from the ground or the picking frame, but there is a certain distance between one end of the picking pole 1 and the ground to facilitate the movement of the picking pole 1, the picked fruit can enter the corrugated conveying hose 4 and be transported to the ground after falling from the picking pole 1. Alternatively, the output end of the corrugated conveying hose 4 can be located inside the picking frame so that the picked fruit can enter the picking frame. Furthermore, the corrugated conveying hose 4 should be bent as much as possible during use to avoid blockage during fruit transport.
[0021] Reference Figure 1As shown, the pulling member 21 further includes a pull rope 22 disposed on the elastic sheet 2 and a pull plate 23 connected to the other end of the multiple pull ropes 22. The pull rope 22 is connected to the end of the elastic sheet 2 away from the picking rod body 1. The pull plate 23 can be arranged around the outside of the picking rod body 1. When the pull plate 23 is pulled down, the elastic sheet 2 is forced to bend by the pull rope 22, causing the multiple elastic sheets 2 to bend simultaneously away from the axis of the picking rod body 1, thereby opening the clamping picking unit. In order to avoid the phenomenon of mutual entanglement between the pull ropes 22, a limiting hollow rod 3 parallel to its axis is provided on the outer wall of the picking rod body 1, and the tension passes through the limiting hollow rod 3, which can realize the limiting of the pull rope 22.
[0022] Reference Figure 1 As shown, furthermore, in order to facilitate the adjustment of the length of the picking pole 1 to facilitate the picking of fruits at different heights, a telescopic handle 6 is connected to the picking pole 1 via a connecting plate. When the fruit is high, the length of the picking pole 1 can be extended by the telescopic handle 6 to achieve the optimal height at which the picking unit can contact the fruit. After the length of the telescopic handle 6 is adjusted, the length of the pull rope 22 can be set as needed to facilitate the pulling of the pulling member 21, preferably extending to the vicinity of the telescopic handle 6 for easy pulling.
