Description

Technical Field

[0001] This utility model relates to the field of fruit picking technology, and in particular to a highly stable fruit picker. Background Technology

[0002] Fruit harvesters are used to pick fruit from trees that are more than two meters tall. Compared to manual harvesting, they reduce the labor intensity of manual harvesting, improve operational safety, accurately pick fruit to avoid damage, improve fruit quality, and can adapt to different tree shapes and fruit types, allowing for harvesting operations in various environments.

[0003] Conventional fruit pickers are better suited for picking common fruits such as apples, oranges, and pomegranates. However, they pose a greater risk when picking durians. When a durian falls into the support bucket or net, its weight and inertia are transmitted directly to the hand through the handle. This can cause the picker's hand to be unable to withstand the sudden, large inertial force, resulting in the picker slipping from their hand and falling to the ground. To solve this technical problem, this invention proposes a highly stable fruit picker. Utility Model Content

[0004] The main objective of this invention is to provide a highly stable fruit harvester that can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A highly stable fruit harvester includes an outer rod, an inner rod inside the outer rod, a spring inside the outer rod, a first air chamber and a second air chamber inside the outer rod, a movable clamp installed on the outer surface of the outer rod, and a carrying bucket installed on the outer surface of the inner rod.

[0007] Preferably, a square plate is fixedly installed on the inner wall of the outer rod, and the outer surface of the square plate is fixedly installed with the outer surface of the first air pressure chamber. A sealing plug is fixedly installed at the bottom end of the inner rod, and the outer surface of the sealing plug is slidably connected with the inner wall of the first air pressure chamber.

[0008] Preferably, the outer surface of the second air chamber is fixedly installed to the inner wall of the outer rod, the inner wall of the second air chamber is slidably connected to the outer surface of the inner rod, and an air pressure plate is fixedly installed on the outer surface of the outer rod, the outer surface of the air pressure plate is slidably connected to the inner wall of the second air chamber.

[0009] Preferably, the inner side of the outer rod is provided with an inward protrusion, and the inner wall of the protrusion is slidably connected to the outer surface of the inner rod.

[0010] Preferably, a limiting plate is fixedly installed on the inner wall of the outer rod, and a pressing plate is fixedly installed on the outer surface of the inner rod. The inner wall of the limiting plate is slidably connected to the outer surface of the inner rod, and the outer surface of the pressing plate is slidably connected to the inner wall of the outer rod.

[0011] Preferably, the spring is sleeved on the outer surface of the inner rod, the top end of the spring is fixedly installed to the bottom surface of the pressing plate, and the bottom end of the spring is fixedly installed to the outer surface of the limiting plate.

[0012] Preferably, a pressure stabilizing channel is provided on the inner side of the outer rod, one end of the pressure stabilizing channel is connected to the outside of the outer rod, and the other end of the pressure stabilizing channel is connected to the inside of the outer rod located above the pressing plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, through the cooperation of the outer rod, inner rod, spring, first air chamber, second air chamber, movable clamp, and carrying bucket, the durian can be picked from the tree by operating the hydraulic clamp during actual use. When the durian falls downwards, it falls directly into the carrying bucket, and the resulting impact will cause the inner rod to move downwards. As the inner rod moves downwards, it will squeeze the first and second air chambers. The first and second air chambers can buffer the downward impact of the inner rod with their internal air pressure. The spring also provides a buffering effect and assists the first and second air chambers in pushing the inner rod back to its original position. The operator's hand holds the outer rod throughout the process, and only a portion of the force generated by the inner rod is directly transmitted to the outer rod. Compared with conventional harvesters, this invention solves the problem that the weight and inertia of the durian are directly transmitted to the hand through the rod, causing the harvester's hand to be unable to withstand the large inertial force brought by the sudden impact.

[0015] In this invention, through the cooperation between the inner rod, the pressing plate, the outer rod, and the pressure stabilizing channel, when the inner rod moves downward, it will drive the pressing plate to move downward on the inner wall of the outer rod, thereby reducing the air pressure in the space above the pressing plate. Although this can buffer the impact force, under the multiple buffering effects of the equipment, the force of the impact force directly transmitted to the outer rod will increase. Therefore, the pressure stabilizing channel can keep the external air and the air above the pressing plate stable, thereby making full use of the buffering measures below.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, a highly stable fruit picker includes an outer rod 1, an inner rod 2 inside the outer rod 1, a spring 3 inside the outer rod 1, a first pressure chamber 4 and a second pressure chamber 5 inside the outer rod 1, a movable clamp 6 mounted on the outer surface of the outer rod 1, and a carrying tank 7 mounted on the outer surface of the inner rod 2. In actual use, the durian can be picked from the tree by operating the hydraulic clamp. When the durian falls downwards, it will fall directly into the carrying tank 7. The impact force generated will cause the inner rod 2 to move downwards. When the inner rod 2 moves downwards, it will squeeze the first pressure chamber 4 and the second pressure chamber 5. The air pressure chamber 5, the first air pressure chamber 4, and the second air pressure chamber 5 can buffer the downward impact force of the inner rod 2 with the internal air pressure. The spring 3 can also provide a buffering effect and assist the first air pressure chamber 4 and the second air pressure chamber 5 in pushing the inner rod 2 back to its original position. The operator's hand holds the outer rod 1 throughout the process. Only part of the force generated by the inner rod 2 is directly transmitted to the outer rod 1. Compared with conventional harvesters, this solves the problem that the weight and inertia of the durian are directly transmitted to the hand through the rod, causing the harvester's hand to be unable to withstand the large inertial force brought by the instant.

[0024] A square plate 8 is fixedly installed on the inner wall of the outer rod 1. The outer surface of the square plate 8 is fixedly installed on the outer surface of the first air pressure chamber 4. A sealing plug 9 is fixedly installed at the bottom end of the inner rod 2. The outer surface of the sealing plug 9 is slidably connected to the inner wall of the first air pressure chamber 4. The outer rod 1 can provide support for the second air pressure chamber 5 and also provides support for the first air pressure chamber 4 through the square plate 8. When the inner rod 2 moves downward, it can push the sealing plug 9 to move downward on the inner wall of the first air pressure chamber 4. When it moves, it can squeeze the air inside the first air pressure chamber 4 and use air pressure to buffer part of the downward impact force of the inner rod 2.

[0025] The outer surface of the second air chamber 5 is fixedly installed to the inner wall of the outer rod 1. The inner wall of the second air chamber 5 is slidably connected to the outer surface of the inner rod 2. An air pressure plate 10 is fixedly installed on the outer surface of the outer rod 1. The outer surface of the air pressure plate 10 is slidably connected to the inner wall of the second air chamber 5. When the inner rod 2 moves downward, it can drive the air pressure plate 10 to move on the inner wall of the second air chamber 5, thereby squeezing the air in the second air chamber 5 located below the air pressure plate 10, thus buffering part of the impact force.

[0026] The inner side of the outer rod 1 is provided with an inward protrusion 11. The inner wall of the protrusion 11 is slidably connected to the outer surface of the inner rod 2. This protrusion 11 can provide support for the inner rod 2, so that the inner rod 2 is less likely to shift or misalign when it moves, making the equipment more stable during use.

[0027] A limiting plate 12 is fixedly installed on the inner wall of the outer rod 1, and a pressing plate 13 is fixedly installed on the outer surface of the inner rod 2. The inner wall of the limiting plate 12 is slidably connected to the outer surface of the inner rod 2, and the outer surface of the pressing plate 13 is slidably connected to the inner wall of the outer rod 1. When the pressing plate 13 moves downward, it will also squeeze the air located inside the outer rod 1 above the limiting plate 12 and below the pressing plate 13, thereby alleviating some of the impact force.

[0028] Spring 3 is sleeved on the outer surface of inner rod 2. The top end of spring 3 is fixedly installed on the bottom surface of pressing plate 13, and the bottom end of spring 3 is fixedly installed on the outer surface of limiting plate 12. Spring 3 can push pressing plate 13 upward with limiting plate 12 as the fixed point. When inner rod 2 moves downward, spring 3 can buffer the impact force of pressing plate 13, and can also assist the first air chamber 4 and the second air chamber 5 in pushing inner rod 2 back to its original position through the elasticity of spring 3 itself.

[0029] A pressure stabilizing channel 14 is provided on the inner side of the outer rod 1. One end of the pressure stabilizing channel 14 is connected to the outside of the outer rod 1, and the other end of the pressure stabilizing channel 14 is connected to the inside of the outer rod 1 located above the pressing plate 13. When the inner rod 2 moves downward, it will drive the pressing plate 13 to move downward on the inner wall of the outer rod 1, thereby reducing the air pressure in the space above the pressing plate 13. Although this can buffer the impact force, under the multiple buffering effects of the equipment, the force of the impact force directly transmitted to the outer rod 1 will increase. Therefore, the pressure stabilizing channel 14 can keep the external air and the air above the pressing plate 13 stable, thereby making full use of the buffering measures below.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
