Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a pneumatic vibration device for harvesting walnuts. Background Technology

[0002] Walnuts are an important economic forest tree species in my country, with their fruits being rich in nutrients and having high economic value. Currently, for walnuts growing high on the trunk, the main harvesting methods include manual knocking with bamboo poles and mechanical vibratory harvesting. Manual knocking with bamboo or wooden poles is labor-intensive, inefficient, and requires highly skilled operators, posing safety risks associated with working at heights. Furthermore, indiscriminate knocking can easily damage the fruiting branches of the tree, affecting the following year's yield. While large-scale mechanical vibratory harvesters are highly efficient, they are only suitable for large-scale, standardized orchards and have poor adaptability to complex terrain and scattered planting in mountainous orchards. Additionally, the purchase and operation costs of such equipment are high.

[0003] Therefore, there is an urgent need for a portable walnut harvesting tool that is easy to operate, can effectively protect the branches and trunks of the fruit tree, and is suitable for various terrains. Summary of the Invention

[0004] In order to overcome the problems of low efficiency, high danger, and easy damage to trees caused by manual knocking in the prior art, as well as the high cost and poor adaptability of large-scale harvesting machinery, this utility model provides a pneumatic vibration device for harvesting walnuts.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A pneumatic vibration device for harvesting walnuts mainly includes a long rod 1, a cylinder 2, a U-shaped clamp 3, an air intake control mechanism 4, and a high-pressure air source 5. The long rod 1 is a hollow long tube. The cylinder 2 is installed inside the front end of the long rod 1. The U-shaped clamp 3 is fixedly installed at the end of the telescopic rod of the cylinder 2. The air intake control mechanism 4 is installed at the tail end of the long rod 1. The cylinder 2 and the high-pressure air source 5 are connected through a hose. A control valve is installed on the hose. The air intake control mechanism 4 is electrically connected to the control valve. The high-pressure air source 5 is a portable air compressor or a high-pressure gas cylinder.

[0006] Furthermore, the intake control mechanism 4 includes a battery, a controller 41, and a trigger switch 42. The battery is electrically connected to the controller 41, the trigger switch 42, and the control valve. The controller 41 is electrically connected to the trigger switch 42 and the control valve, respectively, and is used to adjust the extension frequency and extension formation.

[0007] Furthermore, the hose is inserted inside the long rod 1.

[0008] Furthermore, the cylinder 2 is a double-acting cylinder, ensuring output force in both directions.

[0009] Furthermore, the long rod 1 is made of carbon fiber composite material or high-strength aluminum alloy to reduce the overall weight.

[0010] Furthermore, the long pole 1 is a multi-segment telescopic or detachable structure to facilitate transportation and adapt to harvesting needs at different heights.

[0011] The beneficial effects of this utility model are: This invention utilizes high-pressure gas as a power source to generate high-frequency, controllable vibration, replacing the repetitive manual swinging motion, greatly reducing labor intensity and improving harvesting efficiency. By vibrating and shaking the branches, it avoids hard impacts and knocks, effectively reducing damage to fruiting branches and bark, which is beneficial to the growth and fruiting of the fruit trees in the following year. Operators can stand in a safe position to harvest, avoiding the risks of prolonged upward work and high-altitude climbing. Even when climbing to harvest, there is no need to swing a pole to knock, ensuring the stability of the harvester's center of gravity and avoiding the danger of falling. Attached Figure Description

[0017] This utility model discloses a pneumatic vibration device for harvesting walnuts. The device mainly includes a long rod 1, a cylinder 2, a U-shaped clamp 3, an air intake control mechanism 4, and a high-pressure air source 5. The long rod 1 is a hollow tube. The cylinder 2 is installed inside the front end of the long rod 1. The U-shaped clamp 3 is fixedly installed at the end of the telescopic rod of the cylinder 2. The air intake control mechanism 4 is installed at the tail end of the long rod 1. The cylinder 2 and the high-pressure air source 5 are connected via a flexible hose, on which a control valve is installed. The air intake control mechanism 4 is electrically connected to the control valve. The high-pressure air source 5 is a portable air compressor or a high-pressure gas cylinder. Before operation, the cylinder 2 is connected to the high-pressure air source 5, the air intake control mechanism 4 is activated, and the long rod 1 is operated to move the U-shaped clamp 3... Once positioned appropriately on the target branch, the equipment is activated via the air intake control mechanism 4. The cylinder 2 reciprocates, pushing and pulling the branch to create vibration, thus completing the walnut harvest. This invention utilizes high-pressure gas as power to generate high-frequency, controllable vibration, replacing the repetitive manual swinging motion, greatly reducing labor intensity and improving harvesting efficiency. By vibrating and shaking the branch, hard impacts and knocks are avoided, effectively reducing damage to the fruiting branches and bark, which is beneficial to the tree's growth and fruiting in the following year. The operator can stand in a safe position to harvest, avoiding the risks of prolonged overhead work and high-altitude climbing. Even when climbing to harvest, there is no need to swing a pole, ensuring the harvester's center of gravity is stable and avoiding the danger of falling.

[0018] The intake control mechanism 4 includes a battery, a controller 41, and a trigger switch 42. The battery is electrically connected to the controller 41, the trigger switch 42, and the control valve. The controller 41 is electrically connected to the trigger switch 42 and the control valve, respectively, and is used to adjust the extension frequency and extension formation.

[0019] The hose is inserted inside the long rod 1 to prevent the hose from being exposed, avoid the hose from scratching the branches, which would affect operation and improve service life.

[0020] The cylinder 2 is a double-acting cylinder, ensuring output force in both directions.

[0021] The long rod 1 is made of carbon fiber composite material or high-strength aluminum alloy to reduce the overall weight.

[0022] The long pole 1 is a multi-section telescopic or detachable structure to facilitate transportation and adapt to harvesting needs at different heights.

[0023] Work process: Before starting work, connect cylinder 2 to high-pressure air source 5, start air intake control mechanism 4, operate long rod 1 to make U-shaped clamp 3 lock into the appropriate position on the target branch, start the equipment through air intake control mechanism 4, cylinder 2 reciprocates, pushes and pulls the branch to create vibration, and the walnuts can be harvested. This utility model uses high-pressure gas as power to generate high-frequency, controllable vibration force, replacing the manual action of repeatedly swinging the rod, greatly reducing labor intensity and improving harvesting efficiency. By vibrating and shaking the branches, hard impact and knocking are avoided, which can effectively reduce damage to the fruiting mother branches and bark, which is beneficial to the growth and fruiting of the fruit trees in the following year. The operator can stand in a safe position to harvest, avoiding the risks of long-term upward work and high-altitude climbing. Even when climbing to harvest, there is no need to swing the rod to knock, ensuring the stability of the harvester's center of gravity and avoiding the danger of falling.
