Description

Technical Field

[0001] This utility model relates to the field of rubber tree tapping technology, and in particular to a rubber tree stimulation device. Background Technology

[0002] Currently, approximately 98% of commercially available natural rubber comes from rubber trees. Natural rubber possesses strong elasticity and excellent insulation, plasticity, water and gas impermeability, and tensile strength. After proper processing, it exhibits superior properties such as acid and alkali resistance, heat resistance, cold resistance, pressure resistance, and abrasion resistance. It is widely used in transportation, medical and health fields, machinery manufacturing, aerospace, and daily life, making it an important industrial raw material and strategic resource. Natural rubber is primarily harvested manually by tapping the rubber tree. Workers use tapping knives to cut into the bark, usually at night, to maximize latex flow. The latex is collected in containers and undergoes coagulation and drying processes to obtain natural rubber. The collected latex is then sent to processing plants for further processing. By rationally controlling the process parameters at each stage, high-quality rubber products can be obtained. To increase latex production, ethylene aqueous solutions or ethylene gas are generally used for stimulation. The main technology of short-line rubber tapping using air spurs is ethylene gas. A retractable air bag is filled with gas and connected to a device fixed to the tree trunk. The pressure in the air bag forces the gas to be transported to the device on the tree trunk, thereby stimulating the rubber production through the stimulation of ethylene gas.

[0003] However, in existing equipment, improper operation during gas filling can easily waste gas, and it is not convenient to quickly replace the gas bag. Furthermore, the gas bags in existing equipment are easily damaged by insects or branches, causing them to leak and affecting the stimulation effect. Utility Model Content

[0004] The purpose of this invention is to provide a rubber tree stimulation device in which an air bag and a rigid air chamber bottle are quickly connected by an air needle and an air valve. The air valve ensures the air bag is sealed, making it easy and quick to replace the air bag. The device is fixedly connected by a threaded cap and a connecting cylinder.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A rubber tree stimulation device includes a rigid air chamber bottle that is hollow inside and open at one end. A rigid air tube is connected to the periphery of the rigid air chamber bottle. An air needle is connected to the end of the rigid air tube away from the rigid air chamber bottle. An air bag is inserted through the air needle. The air bag is provided with a one-way air valve. The air needle passes through the air valve and is connected to the air bag. The air valve and the air needle are in sliding cooperation. An air inlet pipe is connected to the end of the air bag away from the air valve. A piston is inserted into the other end of the air inlet pipe.

[0006] A further feature of this invention is that: a limiting ring is provided at the connection between the air needle and the rigid air tube; a threaded cover is slidably and rotatably fitted on the periphery of the rigid air tube; the inner wall of the threaded cover is threaded; a connecting cylinder is provided on the outer side of the air valve; and the threaded cover is threadedly connected to the connecting cylinder.

[0007] A further feature of this invention is that the air valve includes a valve body, a valve core, and an elastic reset member. The valve body is hollow inside and open at both ends. The valve body is inserted into one end of the air bag and is sealed to the air bag. The valve core is located inside the valve body. The elastic reset member is located between the valve body and the valve core. The connecting cylinder is located at one end of the air bag near the valve body and is sleeved around the periphery of the valve body.

[0008] A further feature of this invention is that the air bag comprises an outer layer, a middle layer, and an inner layer. The outer layer is a composite wear-resistant canvas coating, the middle layer is an elastic rubber layer plus a sponge protective layer, the sponge protective layer is filled with an insect repellent, and the inner layer is a PE / PA co-extruded film used to ensure that the air bag maintains pressure and does not leak for a long time.

[0009] A further feature of this invention is that an iron ring is provided at the opening end of the hard air chamber, and the iron ring is used to fix the hard air chamber to the rubber tree.

[0010] A further feature of this invention is that the rigid gas chamber bottle is made of rigid plastic, and the rigid gas tube is made of metal.

[0011] In summary, this utility model has the following beneficial effects: Firstly, the gas bag in this invention serves as a gas storage container that can store high-pressure gas. It is then delivered to the rigid gas tube via a gas needle. The gas reaches the rigid gas chamber bottle and acts on the rubber tree bark layer, simulating natural damage stimulation and promoting the secretion of sap. The gas needle and the one-way gas valve form a quick connection, facilitating rapid replacement of the gas bag. During the replacement process, the one-way gas valve ensures that the gas bag will not leak, and the gas needle can effectively prevent gas leakage from the rigid gas chamber bottle.

[0012] Secondly, the threaded connection between the threaded cap and the connecting cylinder in this utility model enables quick installation. Compared with the traditional snap-fit ​​connection, the threaded connection has higher sealing reliability and is especially suitable for high-pressure gas environments. It can effectively prevent gas leakage. The valve core and the elastic reset component constitute a dynamic sealing system. When the gas needle is inserted into the gas valve, it pushes open the valve core and the gas enters the hard gas chamber. After the gas needle is pulled out, the reset component pushes the valve core to reset, ensuring that the gas cannot flow back.

[0013] Thirdly, the outer composite wear-resistant canvas coating of the air bag in this utility model can withstand mechanical damage such as scratches from tree branches and collisions from stones. The middle elastic rubber layer provides deformation buffer after inflation, preventing the air bag from over-expanding and rupturing. The insect repellent filled in the sponge protective layer can form a continuous insect-repelling barrier. The inner layer ensures that the pressure of the air bag remains stable after inflation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Examples, such as Figures 1 to 3As shown, a rubber tree stimulation device includes a hollow, open-ended rigid gas chamber bottle 1, with the open end connected to the bark of a rubber tree. A rigid gas tube 2 is connected to the periphery of the rigid gas chamber bottle 1. An air needle 3 is connected to the end of the rigid gas tube 2 away from the rigid gas chamber bottle 1. An air bag 5 is inserted through the air needle 3 and is filled with stimulating gas to stimulate the rubber tree to produce latex. The air bag 5 is provided with a one-way valve 4 leading to the air bag 5. The air needle 3 passes through the air valve 4 and is connected to the air bag 5. The air valve 4 and the air needle 3 are in sliding cooperation. The air needle 3 connects to the air bag 5 by passing through the air valve 4. An air inlet pipe 6 is connected to the end of the air bag 5 away from the air valve 4. A piston 61 is inserted into the other end of the air inlet pipe 6. When the air bag 5 is depleted, the piston 61 is opened, and stimulating gas is introduced through the air inlet pipe 6.

[0020] A limiting ring 21 is provided at the connection between the air needle 3 and the rigid air tube 2. A threaded cover 22 is provided on the circumference of the rigid air tube 2 for sliding and rotating. The limiting ring 21 is used to prevent the threaded cover 22 from falling off. The inner wall of the threaded cover 22 is threaded. A connecting cylinder 41 is provided on the outer side of the air valve 4. The threaded cover 22 is threadedly connected to the connecting cylinder 41.

[0021] The gas valve 4 includes a valve body 42, a valve core 43, and an elastic reset member 44. The valve body 42 is hollow inside and open at both ends. The valve body 42 is inserted into one end of the gas bag 5 and is sealed to the gas bag 5. The valve core 43 is located inside the valve body 42. The elastic reset member 44 is located between the valve body 42 and the valve core 43. The connecting tube 41 is located at one end of the gas bag 5 near the valve body 42 and is sleeved around the periphery of the valve body 42. When the gas needle 3 is inserted, the gas needle 3 springs open the valve core 43, passes through the valve body 42, and connects to the gas bag 5. The gas bag 5 communicates with the rigid gas chamber bottle 1 through the gas needle 3.

[0022] The air bag 5 includes an outer layer 51, a middle layer 52 and an inner layer 53. The outer layer 51 is a composite wear-resistant canvas coating, the middle layer 52 is an elastic rubber layer + sponge protective layer, the sponge protective layer is filled with insect repellent, and the inner layer 53 is a PE / PA co-extruded film used to ensure that the air bag 5 maintains pressure for a long time without leakage.

[0023] An iron ring 11 is provided at the opening end of the hard gas chamber. The iron ring 11 is used to fix the hard gas chamber to the rubber tree. The hard gas chamber bottle 1 is made of hard plastic, and the hard gas tube 2 is made of metal.

[0024] Instructions for use: With the opening of the hard gas chamber bottle 1 facing the rubber tree, insert the iron ring 11 on it into the bark of the rubber tree and fix it in place. With the side of the hard gas chamber bottle 1 connected to the hard gas tube 2 facing down, take out the gas bag 5 filled with irritating gas and with the end with the gas valve 4 facing up. Insert the gas needle 3 at the lower end of the hard gas tube 2 into the gas valve 4 to connect it to the gas bag 5. Thread the threaded cap 22 to the connecting cylinder 41 on the gas bag 5 to fix the gas bag 5 at the lower end of the hard gas chamber. Through the air pressure in the gas bag 5, the irritating gas is pushed from the gas needle 3 through the hard gas tube 2 into the hard gas chamber bottle 1, causing it to react with the bark of the rubber tree. When the gas or pressure in the air bag 5 is insufficient, the air bag 5 needs to be replaced. Simply open the threaded cap 22 and pull out the air needle 3. This makes it convenient for staff to replace the air bag 5, which is filled with irritating gas. This also allows staff to carry the air bag 5 filled with irritating gas directly for replacement, avoiding the need to carry an air pump. When inflating the air bag 5, simply open the piston 61 and use an air pump to quickly inflate it through the air inlet pipe 6.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
