Description

Technical Field

[0001] This invention relates to an agricultural and horticultural implement, specifically a novel high-branch fruit picker. Background Technology

[0002] A fruit picker is a horticultural tool used to harvest fruit from high branches. Because fruit trees bear fruit over a large area and at considerable height, most orchards currently rely on manual harvesting. In higher areas, ladders are needed, resulting in high labor intensity, low harvesting efficiency, and safety hazards. To address this, fruit picking devices have been developed to facilitate fruit harvesting from trees. Current fruit pickers typically consist of a telescopic pole, a loop attached to the pole, and a cloth bag attached to the loop to catch the fruit, thus solving some of the problems associated with harvesting fruit from high branches. One type of fruit picker consists of an operating rod, a steel ring, a net bag, a fruit conveying belt, a scissor with a narrow opening, and a branch pressing hook. During operation, the steel ring at the top of the operating rod is placed over the fruit to be picked, and the operating rod is pulled. The fruit stalk or branch automatically slides into the "V"-shaped scissor opening and is cut off under the pull. The fruit with the broken stalk falls into the net bag threaded onto the steel ring, or it can be slowly slid down into the fruit container under the combined action of gravity and friction of the tube wall through a tubular fruit conveying belt sewn to the bottom of the net bag. However, existing fruit pickers generally suffer from poor fruit-picking effect, complicated operation, and low efficiency. The main reason for this is that the fruiting branches are usually quite slender and sway in the air. Current fruit pickers all have a common problem: they do not fix the fruiting branches in place. They only pull the fruit picker downwards, but since the fruiting branches are generally thin, the fruit picker has no point of leverage. The fruiting branches sway in the air and cannot exert force, so the fruit-picking efficiency is low and the effect is poor. This is very unfavorable for the actual use by fruit farmers. In other words, they are basically not easy to use. In actual production, there is an urgent need for a practical and effective high-branch fruit picker. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a novel high-branch fruit picker that overcomes the main issue of conventional fruit pickers lacking a fixed fruiting branch. The design aims to create a high-branch fruit picker applicable to most fruit trees. The technical solution is as follows: A novel high-branch fruit picker comprises a telescopic operating rod, a fruit-feeding and conveying device, and a fruit-pulling device. The fruit-feeding and conveying device consists of a large-opening end of a shaped fruit-feeding funnel fixed at two points at the front end of the first section of the telescopic operating rod, with a fruit-feeding belt connected to the small-opening end of the funnel. The fruit-pulling device consists of a three-pronged branch-fixing fork formed by three short columns on the same outer circumference, forming acute angles with each other and the same acute angle as the front end of the telescopic operating rod, and in the opposite direction to the main body of the funnel. A sliding sleeve mechanism is fitted adjacent to the large opening of the funnel. The sliding sleeve mechanism is fitted outside the shaped fruit-feeding funnel on the first section of the telescopic operating rod. Two radially recessed grooves perpendicular to the shaped fruit-grafting funnel are provided at corresponding positions on the first section of the telescopic operating rod, and a matching sliding sleeve with built-in protrusions is provided. A limit clip and a spring are provided at corresponding positions on the first section of the telescopic operating rod at its rear end, ensuring that the sliding sleeve is always close to the shaped fruit-grafting funnel. At the same time, two radially perpendicular positioning plates are provided in the middle of the sliding sleeve, and a fruit-pulling rod is connected by positioning and bolts. The fruit-pulling rod and the sliding sleeve are provided with torsion springs at the positioning plates, so that the fruit-pulling rod is normally raised in the opposite direction to the main body of the shaped fruit-grafting funnel on the sliding sleeve. At the same time, the front end of the fruit-pulling rod is provided with a radially perpendicular two-pronged fruit-pulling hook opposite to the three-pronged fixed branch. A terminal is provided at an appropriate position on one side of the parallel plane of the fruit-pulling rod and the sliding sleeve after positioning. One end of a pull rope with a length similar to that of the telescopic operating rod after extension is connected to the terminal of the fruit-pulling rod in the raised state, and after being straightened, it is fixed to the terminal on the sliding sleeve, and then extends downward naturally.

[0004] The design concept and main design considerations of this new high-branch fruit picker:

[0005] 1. The key is to overcome the main problem that ordinary fruit pickers cannot fix fruiting branches. This addresses the issue that because fruiting branches are generally quite slender and sway in the air, simply pulling the fruit picker down without a point of leverage makes it inefficient and ineffective, resulting in low picking efficiency and poor results, which is very unfavorable for fruit farmers' practical use.

[0006] 2. This invention employs a three-pronged branch-fixing device fixed at the front end of the first section of the retractable operating rod. This branch is composed of three short columns fixed on the same outer perimeter of the retractable operating rod, forming acute angles with each other and the same acute angle as the front end of the retractable operating rod. These columns are located near the inner side of the large opening of the front-end irregular-shaped fruit-grafting funnel and are oriented in the opposite direction to the main body of the irregular-shaped fruit-grafting funnel. This effectively fixes the fruiting branches. Simultaneously, a fruit-pulling device is provided. This device is fitted onto the irregular-shaped fruit-grafting funnel of the first section of the retractable operating rod. It utilizes two radial center lines perpendicular to the irregular-shaped fruit-grafting funnel, with corresponding recessed grooves and matching sliding sleeves with built-in protrusions, and a limiting device at a corresponding position on the rear end of the first section of the retractable operating rod. The spring in the sleeve and the set ensures that the sliding sleeve is always close to the irregular fruit-receiving funnel. Two perpendicular positioning plates are located in the middle of the sliding sleeve. A fruit-pulling rod is connected to the positioning plates and bolts. A torsion spring is installed at the positioning plates on the fruit-pulling rod and the sliding sleeve, ensuring that the fruit-pulling rod is normally raised in the opposite direction to the main body of the irregular fruit-receiving funnel on the sliding sleeve. The front end of the fruit-pulling rod has a radially perpendicular two-pronged fruit-pulling hook opposite the three-pronged fixed branch. A terminal block is located at an appropriate position on one side of the parallel plane of the fruit-pulling rod and the sliding sleeve after positioning. One end of a pull rope, with an extension similar to that of the telescopic operating rod, is connected to the terminal block of the raised fruit-pulling rod. After being straightened, it is fixed to the terminal block on the sliding sleeve and then extends downwards naturally.

[0007] 3. The fruit-picking device, constructed using the above structure, activates the sliding sleeve and fruit-pulling rod by pulling the rope, causing them to move backward. Simultaneously, this pulls the two-pronged fruit-pulling hooks downward and backward, effectively pulling the fruit. At this point, no pulling force is applied to the three-pronged fixed branch; only the sliding sleeve mechanism and the three-pronged fixed branch move relative to each other. Therefore, the fruit positioned by the three-pronged fixed branch can be easily pulled down and falls into the irregularly shaped fruit-receiving funnel and the connected fruit-transfer belt, thus transferring it to the container and successfully completing a high-branch fruit-picking operation.

[0008] This invention patent technology has a simple structure, is easy to manufacture, has reliable performance, is safe to operate, is convenient to use, has low cost, and has a wide range of applications. It is widely applicable to the harvesting of fruits with stems that are easily damaged, such as apples, pears, persimmons, oranges, apricots, peaches, and pomegranates. It can better meet the needs of orchards and family production, and has good economic benefits after promotion. Attached Figure Description

[0015] See Figure 1 Figure 2 Figure 3A novel high-branch fruit picker comprises a telescopic operating rod 1, a fruit-feeding and conveying device, and a fruit-pulling device. The fruit-feeding and conveying device consists of a shaped fruit-feeding funnel 2 with a large opening fixed at two points at the front end of the first section of the telescopic operating rod 1. The smaller opening of the shaped fruit-feeding funnel is connected to a fruit-feeding belt 3. The fruit-pulling device consists of a three-pronged branch-fixing fork 4 formed by three short columns on the same outer circumference, forming acute angles with each other and the same acute angle as the front end of the telescopic operating rod, and in the opposite direction to the main body of the shaped fruit-feeding funnel, fixed near the front end inside the large opening of the shaped fruit-feeding funnel on the first section of the telescopic operating rod. A sliding sleeve mechanism is fitted adjacent to the large opening of the shaped fruit-feeding funnel. The sliding sleeve mechanism is fitted outside the shaped fruit-feeding funnel on the first section of the telescopic operating rod, and is formed by recessed grooves along two radial center lines perpendicular to the shaped fruit-feeding funnel, located at corresponding positions on the first section of the telescopic operating rod. A sliding sleeve 5 with built-in protrusions is matched with it, and a limit card 6 and a spring 7 are provided at the corresponding position on the first section of the telescopic operating rod at its rear end, so that the sliding sleeve is always close to the side of the irregular fruit funnel. At the same time, two positioning plates 8 are provided in the middle of the sliding sleeve, which are perpendicular to it. A fruit pulling rod 10 is connected by a positioning bolt 9. The fruit pulling rod 10 and the sliding sleeve 5 are provided with torsion springs 11 at the positioning plates 8, so that the fruit pulling rod 10 is normally raised on the sliding sleeve 5 in the opposite direction to the main body of the irregular fruit funnel 2. The front end of the fruit pulling rod 10 is provided with a radially vertical two-pronged fruit pulling hook 12 opposite to the three-pronged fixed branch fork 4. At the same time, a terminal post 13 is provided at an appropriate position on one side of the parallel plane of the fruit pulling rod 10 and the sliding sleeve 5 after positioning. One end of the pull rope 14, which is close to the extension of the telescopic operating rod, is connected to the terminal post of the fruit pulling rod in the raised state. After being straightened, it is fixed to the terminal post on the sliding sleeve and extends downward naturally.

[0016] When using this invention, pulling the rope will cause the sliding sleeve and the fruit-pulling rod to move backward in a coordinated motion, which in turn drives the two-pronged fruit-pulling hooks to pull downward and backward, thus pulling the fruit. At this time, no pulling force is applied to the three-pronged fixed branch fork; only the sliding fruit-pulling device moves relative to the three-pronged fixed branch fork. Therefore, the fruit positioned by the three-pronged fixed branch fork can be easily pulled down and fall into the irregularly shaped fruit-receiving funnel and the connected fruit conveyor belt, and then transferred to the container, successfully completing a high-branch fruit-picking operation.

[0017] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
