Description

Technical Field

[0001] This invention relates to the field of trifoliate orange collection technology, specifically to a gas absorption and collection device for trifoliate orange grown under mulch. Background Technology

[0002] Mulched cultivation of trifoliate orange refers to a standardized orchard cultivation model that uses medicinal trifoliate orange trees such as sour orange as the cultivation object and covers the ground surface with plastic film or weed control cloth. The film isolates the soil from the outside air, which can increase the temperature and retain moisture, suppress weeds and reduce damage, and stabilize the root zone microenvironment. It is also a special experimental planting method for collecting volatile gases from trifoliate orange plants in situ in the field. In existing technologies, the sealing structure between components of the air absorption and collection device for mulched trifoliate orange cultivation is easily affected by the shape of the soil in the field during operation. This can cause misalignment when the components are in contact with the material, resulting in reduced air absorption efficiency. Furthermore, during the absorption of the material, the device can easily cause air to be drawn into the mulch, which can block the holes and affect the smooth flow of air. Therefore, a new design has been developed to address these issues. Summary of the Invention

An interventional tube has a long cylindrical structure, and one end of the interventional tube is fixedly connected to the outside of a stable housing.

[0005] The vacuum feeder has a flow pipe inside, and a limiting block is fixedly connected to the inner wall of the flow pipe near the intervention tube. The limiting block is frictionally adapted to the outer side of the intervention tube.

[0006] A connecting tube is fixedly connected to the outside of the collection bag on the side away from the connecting end. A tube plug is inserted and removed from the outside of the connecting tube, and a rubber ring is fixedly connected to the inner wall of the tube plug near the connecting tube.

[0007] A connecting pipe is fixedly connected to the outside of the stable shell. A pipe slot is opened inside the connecting pipe.

[0009] A receiving pipe is fixedly connected to the upper side of the inner wall of the groove on the disc surface. A support mechanism is slidably connected to the outer side of the feeding shell. An expansion plate is fixedly connected to the center of the bottom of the feeding shell. A support frame is fixedly connected to the opposite side of the expansion plate and the feeding shell.

[0010] The support mechanism includes a support rod, the outer side of which is slidably connected to the outer side of the feed housing, a support device is fixedly connected to the bottom of the support rod, and a second spring is sleeved on the outer side of the support rod.

[0011] The support device includes a support plate, a limit plate fixedly connected to the top of the support plate, a plastic film fixedly connected to the bottom of the support plate, a spherical block inside the plastic film, and a support block fixedly connected to the outside of the plastic film.

[0012] This invention provides a gas absorption and collection device for grown trifoliate orange under film mulching. It has the following beneficial effects: 1. In this film-covered plantation of trifoliate orange, when the material moves inside the pipeline, it collides with the pipeline, which can easily cause the pipeline to vibrate. When the impact is transmitted to the telescopic rod, the telescopic rod compresses and contracts the first spring, thereby playing a role in shock absorption and buffering. This reduces the pipeline vibration caused by the airflow impact, lowers the risk of air leakage in the overall device, improves the equipment's ability to collect materials, maintains a continuous and stable airflow velocity inside the pipeline, and ensures continuous operation of the equipment.

[0013] II. The gas absorption and collection device for mulched trifoliate orange has a stabilizing shell with a funnel structure to collect and guide the material, reducing the material's movement range. The friction shell is made of plastic to increase the elasticity of the component surface, reduce the collision between the material and the component, and avoid damage to the material. The intervention tube increases the contact area between the stabilizing shell and the inside of the vacuum conveyor, further reducing the material's movement space and facilitating unified material collection.

[0014] III. This film-covered trifoliate orange aeration and collection device connects the connecting pipe to the stable shell to guide and connect the material, facilitating material transfer and transportation, and maintaining the airtightness between components. The grid plate prevents external impurities from entering, and the valve body controls the sealing effect of the external connecting pipe. During the material aeration process, the valve body remains closed, thereby maintaining the airtightness between the stable shell and the connecting pipe. After the equipment finishes operation, the fan generates airflow to flush the inside of the equipment, thus cleaning the inner walls of the components. This cleans dust and impurities from the inner walls of the components and keeps the inside of the pipes dry, preventing material from getting stuck inside the components, maintaining smooth airflow, and ensuring continuous operation of the equipment.

[0015] IV. In this membrane-grown trifoliate orange gas absorption and collection device, the outer expansion plate guides the material feeding. During the material suction process, the outer expansion plate supports the membrane, acts as a barrier, and maintains space between the membrane and the feeding tray. This prevents the membrane from sticking to the feeding tray due to suction, thus preventing the membrane from clogging the pipe opening and preventing membrane debris from entering the pipe, thereby preventing any impact on the equipment's operating performance. The support frame supports the outer expansion plate, thereby increasing the rigidity of the components and maintaining their stability.

[0016] 5. In this film-covered plantation of trifoliate orange, when the feeding device is in contact with the material, the support tool is in contact with the soil. The support tool drives the support rod to compress and contract the second spring, thereby playing a shock-absorbing and buffering role. This buffers the pressure generated when the equipment is connected to the material, reduces the difficulty of equipment operation, and reduces the pressure on the operator's hands. At the same time, according to the soil shape, the support rod compresses and contracts the second spring according to the soil shape, thereby improving the stability of the components when they are connected.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] First embodiment, such as Figures 1 to 3 As shown, the present invention provides a technical solution: a gas absorption and collection device for mulched trifoliate orange cultivation, comprising: Vacuum feeder 1 has a square block structure. A hand-held frame 2 is fixedly connected to the side of the vacuum feeder 1, and a stabilizing device 4 is fixedly connected to the outside of the vacuum feeder 1. The conveying pipe 6 has a tubular structure. One end of the conveying pipe 6 is rotatably connected to an annular block 7, which is rotatably connected to the outside of the stabilizing device 4. The other end of the conveying pipe 6 is threadedly connected to a feeding device 5. An air compressor 3 is installed outside the vacuum feeder 1. The external pipe of the air compressor 3 is fixedly connected to the outside of the vacuum feeder 1 and the pipe is kept in contact. The connecting end 8 has an annular shell structure and is fixedly connected to the outside of the vacuum conveyor 1. A collection bag 9 is rotatably connected to the outside of the connecting end 8. A handheld frame 2 is set on the side of the vacuum conveyor 1, which is placed on the arm of the user to achieve handheld operation. The top of the vacuum conveyor 1 is connected to the air compressor 3. High-pressure compressed air is injected into the cavity at high speed from the middle air inlet. According to the Venturi effect, the high-speed airflow creates a negative pressure in the inner cavity of the suction end. Under the action of the pressure difference between the inside and outside, the material is sucked into the cavity and sprayed out from the discharge end along with the high-speed airflow, realizing the material is transported from the suction inlet to the discharge outlet. The end of the vacuum conveyor 1 near the stabilizing device 4 is the suction inlet, and the side near the collection bag 9 is the discharge outlet. The annular block 7 connects one end of the conveying pipe 6 to the stabilizing device 4 to achieve modular installation. The material is sucked in from the feeding device 5 by the negative pressure, flows through the conveying pipe 6 and the vacuum conveyor 1 to the collection bag 9, and the collection bag 9 collects and stores the material for subsequent processing.

[0021] A connecting pipe 10 is fixedly connected to the outside of the collection bag 9 on the side away from the connecting end 8. A pipe plug 11 is inserted and removed from the outside of the connecting pipe 10, and a rubber ring 12 is fixedly connected to the inner wall of the pipe plug 11 near the connecting pipe 10. The pipe plug 11 is inserted and removed from the connecting pipe 10 to seal the collection bag 9 and maintain its collection function. The rubber ring 12 increases the friction between the pipe plug 11 and the connecting pipe 10, thereby further improving the stability of the components, maintaining the connection between the components, and preventing the components from falling off. At the same time, by inserting and removing the pipe plug 11, the connecting pipe 10 can easily discharge the material inside the collection bag 9, collect the material, avoid storing too much at once, reduce the pressure on the operators, and achieve the function of rapid material discharge.

[0022] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 4 to 5 As shown, the stabilizing device 4 includes: A stabilizing housing 406 has a conical housing structure, and a stabilizing frame 408 is fixedly connected to the outside of the stabilizing housing 406. The telescopic rod 409 has a cylindrical shell structure. One side of the telescopic rod 409 is fixedly connected to the stable shell 406, and a first spring 410 is sleeved on the outer side of the telescopic rod 409. When material moves inside the pipeline, collisions between the material and the pipeline can easily cause vibrations. When the impact is transmitted to the telescopic rod 409, it compresses and contracts the first spring 410, thereby acting as a shock absorber and buffer, reducing pipeline vibration caused by airflow impact, lowering the risk of overall equipment leakage, improving the equipment's material collection capabilities, maintaining a stable airflow velocity inside the pipeline, and ensuring continuous equipment operation.

[0023] Stabilizing device 4 also includes: A friction soft shell 407 is disposed inside the stable shell 406, and the outer side of the friction soft shell 407 is fixedly connected to the inner side of the stable shell 406. The intervention tube 411 has a long cylindrical structure, and one end of the intervention tube 411 is fixedly connected to the outside of the stabilizing housing 406. The stabilizing housing 406 adopts a funnel structure to collect and guide the material, reducing the material movement range. The friction soft shell 407 is made of plastic to increase the elasticity of the component surface, reduce the collision between the material and the component, and avoid damage to the material. The intervention tube 411 increases the contact area between the stabilizing housing 406 and the inside of the vacuum conveyor 1, further reducing the material movement space and facilitating unified material collection.

[0024] The vacuum feeder 1 has an internal flow pipe 13. A limiting block 14 is fixedly connected to the inner wall of the flow pipe 13 near the intervention tube 411. The limiting block 14 is frictionally fitted with the outer side of the intervention tube 411. The flow pipe 13 is used for the flow of high-pressure compressed air to transport materials from the inlet to the outlet. Secondly, the limiting block 14 restricts the intervention tube 411 to prevent the first spring 410 from extending or retracting, thus preventing the components from derailing, avoiding interference with the pipe connections between components, and maintaining smooth airflow.

[0025] A connecting pipe 401 is fixedly connected to the outside of the stable housing 406. A pipe slot 402 is opened inside the connecting pipe 401. An outer connecting pipe 403 is fixedly connected to the outside of the connecting pipe 401 near the pipe slot 402. A fan 412 is fixedly connected to one side of the inner wall of the outer connecting pipe 403. A valve body 405 is fixedly connected to the side of the inner wall of the outer connecting pipe 403 away from the fan 412. A grid plate 404 is fixedly connected to the outside of the outer connecting pipe 403 near the fan 412. The connecting pipe 401 is connected to the stabilizing housing 406 to guide and connect materials, facilitating material transfer and transportation, and maintaining the seal between components. The grating plate 404 prevents external impurities from entering, and the valve body 405 controls the sealing effect of the external connecting pipe 403. During the material absorption process, the valve body 405 remains closed, thereby maintaining the seal between the stabilizing housing 406 and the connecting pipe 401. After the equipment finishes operation, the fan 412 generates airflow to flush the inside of the equipment, thus cleaning the inner walls of the components. This cleans dust and impurities from the inner walls of the components, keeps the inside of the pipes dry, prevents materials from getting stuck inside the components, maintains smooth airflow, and allows the equipment to continue operating.

[0026] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 6 to 9 As shown, the feeding device 5 includes a feeding housing 51. A groove 52 is formed in the middle of the feeding housing 51. A feeding disc 53 is fixedly connected to the lower inner wall of the groove 52. A slot 59 is formed on the outer side of the feeding disc 53. A fixed port 55 is fixedly connected to the top center of the feeding housing 51. The inner side of the fixed port 55 is threaded to one end of the conveying pipe 6. The fixed port 55 is used for connection between the conveying pipes 6, thereby improving the modularity of the components and facilitating disassembly and installation. The slot 59 on the feeding disc 53 provides multiple feeding ports, increasing the material intake and preventing blockage of a single hole, thus preventing any impact on the feeding process.

[0027] A connecting pipe 54 is fixedly connected to the upper side of the inner wall of the groove 52 on the disc surface. A support mechanism 56 is slidably connected to the outer side of the feeding housing 51. An outer expansion plate 57 is fixedly connected to the center of the bottom of the feeding housing 51. A support frame 58 is fixedly connected to the opposite side of the outer expansion plate 57 and the feeding housing 51. The outer expansion plate 57 guides the material feeding. During the material suction process, the outer expansion plate 57 supports the film coating, acts as a barrier for the film coating, and maintains the space between the film coating and the feeding disc 53. This prevents the film coating from sticking to the feeding disc 53 by suction, prevents the film coating from sticking to the pipe opening and prevents film coating debris from entering the pipe, thus preventing the equipment from affecting its operation. The support frame 58 is used to support the outer expansion plate 57, thereby increasing the rigidity of the component and maintaining its stability.

[0028] The support mechanism 56 includes a support rod 561, which is slidably connected to the outer side of the feeding housing 51. A support device 563 is fixedly connected to the bottom of the support rod 561, and a second spring 562 is sleeved on the outer side of the support rod 561. When the feeding device 5 is in contact with the material, the support device 563 is in contact with the soil. The support device 563 drives the support rod 561 to compress and contract the second spring 562, thereby playing a role in shock absorption and buffering. This buffers the pressure generated by the docking of the equipment and the material, reduces the difficulty of equipment operation, and reduces the pressure on the operator's hands. At the same time, according to the shape of the soil, the support rod 561 compresses and contracts the second spring 562 according to the shape of the soil, thereby improving the stability of the components during docking.

[0029] The support device 563 includes a support plate 5631, a limit plate 5632 fixedly connected to the top of the support plate 5631, a plastic film 5633 fixedly connected to the bottom of the support plate 5631, a spherical block 5635 inside the plastic film 5633, and a support block 5634 fixedly connected to the outside of the plastic film 5633. The plastic film 5633 is adapted to the spherical block 5635. When the plastic film 5633 is in contact with the ground, the deformation of the plastic film 5633 causes the spherical block 5635 to move and distribute. The spherical blocks 5635 stack up to support the plastic film 5633, thereby further improving the stability of the component. At the same time, it improves the cushioning effect of the component, reduces wear, and extends the service life of the component. The support block 5634 is set on the plastic film 5633 to increase the stability of the plastic film 5633 in contact with the ground and maintain the supporting effect of the component. The limiting plate 5632 is attached to the outside of the second spring 562 to limit the range of motion of the second spring 562, maintain the deformation range of the second spring 562, and play a certain protective role.

[0030] When in use, the battery is installed on the side of the vacuum feeder 1 away from the handheld frame 2. The battery is electrically connected to the air compressor 3, which facilitates outdoor use of the equipment. At the same time, the battery can be replaced, thus allowing the equipment to operate for a long time. One end of the conveying pipe 6 is connected to the stabilizing device 4, and the other end is connected to the feeding device 5. The side of the stabilizing device 4 away from the conveying pipe 6 is connected to the vacuum feeder 1. An air compressor 3 is installed on the top of the vacuum feeder 1, and a collection bag 9 is installed on the side of the vacuum feeder 1 away from the stabilizing device 4. The vacuum feeder 1 has an inlet on one side near the feed pipe 6 and an outlet on the other side. When the air compressor 3 is started, high-pressure compressed air is injected into the cavity at high speed from the air inlet in the middle of the vacuum feeder 1. According to the Venturi effect, the high-speed airflow creates a negative pressure in the cavity at the suction end. Under the action of the pressure difference between the inside and outside, the material is sucked into the cavity and sprayed out from the discharge end along with the high-speed airflow, thus realizing the conveying of material from the inlet to the outlet, thereby achieving the function of feeding and discharging, and thus realizing the collection operation of material. A handheld bracket 2 is installed on the outside of the vacuum feeder 1. The handheld bracket 2 allows for hand-held placement, making it easy to place on the operator's arm and reducing wrist pressure. The feeding device 5 is equipped with a support mechanism 56. The support mechanism 56 increases the elasticity of the feeding device 5, reduces the pressure generated when the feeding device 5 docks with the material, and has a certain rebound effect, reducing the hand pressure of the operator. Secondly, the outer expansion plate 57 acts as a barrier to the film, retaining space between the film and the component, preventing the suction force from causing the film to stick directly to the feeding tray 53, preventing blockage of the holes, and avoiding affecting the operation of the equipment. The stabilizing device 4 is equipped with a stabilizing shell 406 and a friction soft shell 407. The friction soft shell 407 is made of plastic, which plays a role in shock absorption and buffering, reducing the collision between materials and components, protecting materials, reducing damage to materials, ensuring material quality, and improving the integrity of material collection. Material enters the collection bag 9 and is collected and stored through the collection bag 9. The collection bag 9 is rotatably connected to the connecting end 8, which facilitates overall disassembly and installation. A connecting pipe 10 and a pipe plug 11 are provided on the other side of the collection bag 9. The connecting pipe 10 and the pipe plug 11 are fitted together to seal the component. The connecting pipe 10 and the pipe plug 11 are detachable, which facilitates partial opening of the component for material discharge and collection.
