Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, and in particular to automatic spraying equipment for pepper cultivation in a greenhouse. Background Art

[0002] The automatic sprinkler equipment for greenhouse pepper cultivation uses intelligent irrigation technology. It monitors soil moisture and environmental changes in real time through sensors, automatically adjusts the spraying amount and irrigation time, and ensures uniform and accurate water supply. Compared with traditional irrigation methods, the automatic sprinkler system can effectively save water, reduce labor costs, improve water resource utilization efficiency, and create a more stable growth environment, promoting healthy growth and high yield of peppers. With the development of the Internet of Things and big data technology, automatic sprinkler equipment is developing in the direction of intelligence and precision, promoting more efficient and sustainable agricultural production.

[0003] If liquid flow rate control is not adopted and fertilizer mixing is not performed during the liquid flow process, it will lead to uneven water and fertilizer supply, causing over-humidity or water shortage in some areas, uneven fertilizer distribution, and even fertilizer damage or soil salt accumulation. In addition, the waste of fertilizer and water will reduce irrigation efficiency and affect crop growth, resulting in reduced yield and quality. In the long run, it will also lead to equipment failures, such as pipe blockage, affecting the overall operation. Therefore, liquid flow rate control and fertilizer mixing are the key to ensuring efficient, accurate and water-saving irrigation systems.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs an automatic spraying equipment for pepper cultivation in a greenhouse to solve the above technical problems. Summary of the invention

[0005] The technical objective to be achieved by the present invention is: the technical objective of the present invention is to provide an automatic spraying equipment for pepper cultivation in a greenhouse, which ensures uniform liquid distribution and efficient spraying effect by optimizing the liquid flow rate control, liquid mixing and spraying system, and improves the stability and energy efficiency of equipment operation; through automatic adjustment and precise design, it reduces manual intervention, simplifies operation and maintenance, and at the same time reduces the energy consumption of the equipment and improves the overall work efficiency, thereby realizing efficient and precise irrigation and fertilization in greenhouse cultivation, and reducing resource waste and labor costs.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions: The invention discloses an automatic spraying device for pepper cultivation in a greenhouse, comprising a ground, a greenhouse and a delivery pipe, and also comprising a storage chamber and a flow stabilizing pipe. The greenhouse is installed above the ground, the delivery pipe is installed on the greenhouse, the storage chamber is installed on the delivery pipe, and the flow stabilizing pipe is installed at one end of the delivery pipe close to the greenhouse. The storage chamber drives blades to rotate through the flow of liquid inside the delivery pipe, and the rotating blades drive the rotating blocks to expand outward through the kinetic energy transmitted by the bevel gear, so that the expanded rotating blocks drive the expansion pieces and the extrusion rods to move horizontally, and the horizontally moving extrusion rods drive the sliding blocks to slide back and forth, so that the sliding blocks that slide back and forth control the fertilizer inside the regulating cylinder, and the rotating bevel gears drive the stirring rods and stirring plates to break up the fertilizer inside the regulating cylinder, so that the fertilizer is easier to mix; the flow of liquid inside the delivery pipe drives the blades to rotate and drives the L rods to rotate at the same time, and the rotating L rods further stir the liquid, and at the same time, the motor drives the gears to rotate and drives the expansion pieces to rotate, so as to adjust the flow rate of the liquid inside the bifurcated pipe and the diverter pipe.

[0007] The liquid flow driving mode avoids a lot of manual operations, improves efficiency, and ensures the smooth operation of each link. The equipment can accurately control the distribution of fertilizer in the cylinder by moving the sliding block back and forth to ensure that the fertilizer is delivered to the pepper plants in a reasonable amount. At the same time, the stirring rod and the stirring plate can effectively break up the fertilizer with the rotation of the bevel gear, promote the uniform mixing of fertilizer and soil, and avoid fertilizer agglomeration or clogging of the pipeline. The flow stabilizer helps to stabilize the flow of liquid, avoid the drastic fluctuation of the liquid flow rate, ensure the stability of the spraying equipment during operation, thereby improving the spraying accuracy of the equipment and avoiding insufficient or waste of irrigation caused by unstable flow rate. The motor drives the gear to rotate and adjust the liquid flow rate inside the bifurcated pipe and the diverter pipe, so that the equipment can adjust the intensity and range of liquid spraying according to needs, meet the needs of different crops or different growth stages, and improve the flexibility of greenhouse management. The equipment not only has the functions of automatic spraying and fertilizer delivery, but also combines the functions of fertilizer stirring and breaking up, avoiding the problem of fertilizer deposition or agglomeration, and improving the overall efficiency and stability of the entire equipment. By stabilizing the flow and precisely controlling the spraying of fertilizers and liquids, farmers’ workload is reduced, making greenhouse management more convenient and intelligent.

[0008] The storage chamber comprises a closed chamber, a rotating rod, a conveyor belt, a transmission bevel gear, a reverse bevel gear, a driven bevel gear, a support cylinder, an adjusting cylinder and a connecting pipe. A sealed chamber is installed on the conveying pipe, a rotating rod is installed inside the closed chamber, a blade is installed on the side of the rotating rod, a transmission gear is installed on the left end of the rotating rod, a conveyor belt is installed on the right end of the rotating rod, a transmission bevel gear is installed above the conveyor belt, a transmission bevel gear is installed above the transmission gear, the left side of the transmission bevel gear is a gear structure, the diameter of the left side gear of the transmission bevel gear is the same as the diameter of the transmission gear, the left side gear of the transmission bevel gear is meshed with the transmission gear, and the transmission kinetic energy of the gear and the two ends of the conveyor belt can be better made the same, avoiding the damage of the mechanism caused by the excessive speed of one side, a driven bevel gear is meshed and installed between the transmission bevel gear and the reverse bevel gear, a support cylinder is installed on the periphery of the driven bevel gear, an adjusting cylinder is installed on the upper end of the driven bevel gear, a connecting pipe is installed in communication with the lower end of the adjusting cylinder, and the other end of the connecting pipe is connected to the conveying pipe.

[0009] The mutual meshing design between the transmission bevel gear, the counter bevel gear and the driven bevel gear ensures the precise transmission of power. In particular, the diameter of the gear on the left side of the transmission bevel gear matches that of the transmission gear, so that the transmission kinetic energy at both ends is consistent, effectively avoiding equipment damage or instability caused by uneven rotation speed. This optimized design significantly improves the stability and service life of the equipment. Through the design of the adjustment cylinder and the connecting pipe, the fertilizer can be accurately transported from the adjustment cylinder to the delivery pipe. This structure can control the flow of fertilizer, making the fertilizer application more uniform and accurate, thereby improving the fertilization effect and avoiding waste. The support cylinder outside the driven bevel gear enhances the stability of the entire transmission equipment and avoids loosening or damage of components caused by uneven load or vibration during high-speed operation. The existence of the support cylinder makes the entire structure more solid and more stable during operation. The mechanical transmission structure of the present invention reduces the burden on mechanical components through precise meshing of gears and transmission synchronization. A closed chamber is installed on the delivery pipe to ensure that there is no leakage during the flow of liquid or fertilizer, improve the safety and reliability of the equipment, and also prevent external pollution or impurities from entering the delivery equipment.

[0010] A limiting ring is provided above the driven bevel gear, and a fixed column is installed in an array inside the limiting ring, a rotating block is installed on the fixed column, a tension spring is clamped on the upper end of the rotating block, and the other end of the tension spring is clamped on the driven bevel gear, and a stirring rod is installed in an array on the upper side of the driven bevel gear, and a stirring plate is installed at one outer end of the stirring rod, and the cross-sectional shape of the stirring plate is arc-shaped, and the arc-shaped stirring plate can better grind and clean the inner wall of the adjusting cylinder.

[0011] By setting a limit ring above the driven bevel gear and installing a fixed column and a rotating block inside the limit ring, a stable rotating device is formed. The rotating block is connected to the driven bevel gear through a tension spring to ensure uniform distribution of force during rotation, avoid excessive wear or vibration of mechanical parts due to uneven power, and thus improve the stability and service life of the equipment. The tension spring connects the rotating block to the driven bevel gear and acts as a damper through its elastic properties, reducing the vibration and impact force that may be generated during the movement. This design not only reduces the wear of mechanical parts, but also improves the durability of the equipment, ensuring that the equipment can maintain high working performance during long-term use. The coordination of the stirring rod and the stirring plate with the driven bevel gear makes the stirring process more uniform. The arc-shaped cross-section design of the stirring plate has significant advantages. It can better fit the inner wall of the regulating cylinder, improve the stirring effect, and ensure that the fertilizer or liquid substance is fully mixed and evenly distributed in the regulating cylinder. In addition, the arc-shaped stirring plate can also effectively polish and clean the inner wall of the regulating cylinder, avoiding the residue or agglomeration of fertilizer or liquid substances and preventing pipeline blockage.

[0012] The cross-sectional shape of the rotating block is a "comb" shape, and the rotating block is arranged counterclockwise, which can better squeeze the expansion piece during rotation to prevent the rotating block from getting stuck during rotation. A rotating column for support is installed on the upper end of the rotating block. The rotating column is used to reduce friction during rotation and squeeze the expansion piece more smoothly.

[0013] The cross section of the rotating block is in the shape of a "comb", which can effectively increase the contact area between the rotating block and the opening piece, and form a uniform extrusion effect during the rotation process, which can better dock with the opening piece and provide a stable extrusion force, ensuring the efficient operation of the opening piece, and avoiding functional failure or insufficient extrusion caused by uneven contact. The rotating block adopts a counterclockwise arrangement design, which optimizes the distribution of force during the rotation process, making the contact between the rotating block and the opening piece more stable during movement, and preventing the rotating block from getting stuck or not rotating smoothly. A rotating column is installed at the upper end of the rotating block, and the function of the rotating column is to reduce the friction between the rotating block and other components during the rotation process. This allows the rotating block to rotate more smoothly, reducing the energy loss caused by friction, and also reducing mechanical wear. The use of the rotating column helps to improve the operating efficiency of the equipment and extend its service life. The rotating column reduces friction and resistance, and the extrusion between the rotating block and the opening piece is smoother and more efficient. By optimizing power transmission, the energy consumption of the entire equipment is reduced, and the equipment shows higher efficiency and lower energy consumption during the working process, saving energy and improving work efficiency. Due to the "fun"-shaped cross section and counterclockwise arrangement, the cooperation between the rotating block and the spreader is smoother, avoiding the phenomenon of jamming. This design significantly reduces the risk of equipment failure during operation and enhances the reliability and durability of the equipment. In addition, the rotating column reduces friction, and the contact and movement of the rotating block with other components are smoother, reducing wear and excessive consumption. This not only improves the long-term operating efficiency of the equipment, but also reduces the frequency of repairs and replacement of parts, further reducing maintenance costs.

[0014] The upper end of the support tube is set to a disc shape, and two expansion plates are installed inside the disc shape at the upper end of the support tube. The cross-section of the expansion plate is in the shape of an inferior arc, which can better adapt to the extrusion of the rotating block and increase the friction between the rotating block and the expansion block. An extrusion rod is installed on the side of the expansion plate, and one end of the outer periphery of the extrusion rod is set to an inclined surface, which can slide the limit block on the sliding block more smoothly.

[0015] The cross section of the spreader is designed to be a minor arc shape, which can better adapt to the extrusion of the rotating block. The minor arc shape can form a larger contact area when subjected to force, thereby enhancing the friction between the rotating block and the spreader. The role of increasing friction is to ensure that the equipment will not slip during the rotation process, thereby providing a stable extrusion effect and preventing unstable operation due to insufficient friction. The upper end of the support cylinder is set in a disc shape. This structural design can provide more uniform support and provide sufficient space to install two spreaders. The disc shape allows the spreader to move freely in a larger range, thereby improving the uniformity of extrusion and ensuring the precise processing of the required materials. One end of the outer periphery of the extrusion rod is set as an inclined surface, which can slide the limit block on the sliding block more smoothly. The inclined surface design reduces the resistance during sliding, making the sliding process more stable and smooth, thereby improving the accuracy of operation and the overall performance of the equipment. The inclined surface also helps to evenly distribute the force applied to the limit block, avoiding wear or jamming of components caused by uneven force. The bevel design of the extrusion rod ensures the smooth sliding of the upper limit block on the sliding block, further reducing friction and vibration, making the entire equipment more stable during operation. The bevel design of the extrusion rod helps reduce the phenomenon of stagnation, ensuring that the limit block can slide smoothly on the sliding block, avoiding the problem of equipment jamming due to excessive friction or poor design. The stronger friction between the opening piece and the rotating block, as well as the bevel design of the extrusion rod, reduce unnecessary impact and friction loss between components. Reasonable design of friction helps reduce wear during equipment operation, thereby extending the service life of each component and reducing maintenance costs.

[0016] A sliding groove is provided at the lower end of the adjusting cylinder on the driven bevel gear, and the sliding groove is composed of a semicircular front end and a rectangular rear end. A sliding block is slidably installed inside the sliding groove, and the sliding block is composed of a semicircular front end and a rectangular rear end, and a rectangular groove is provided in the middle of the sliding block. A limiting block is installed under the sliding block, and a restoring spring is clamped at the rear end of the sliding block, and the other end of the restoring spring is clamped on the adjusting cylinder.

[0017] The sliding groove is composed of a semicircular front end and a rectangular rear end, and the front and rear ends of the sliding block match the shape. This ensures that the sliding block can move smoothly in the sliding groove and avoids the phenomenon of stagnation. The sliding process of the sliding block is smoother, and the adjustment task can be completed efficiently, which improves the stability of the equipment. The combined design of the sliding groove and the sliding block enables the sliding block to obtain a larger contact area and ensure smooth sliding during the adjustment process. The rear end of the sliding block is connected to the recovery spring. The function of the recovery spring is to ensure that the sliding block can return to the initial position after the operation is completed, avoiding stagnation or deviation of the sliding block during the adjustment process. The recovery spring provides an automatic reset function, which helps to ensure the consistency of each operation and avoid adjustment errors caused by improper human operation. A limit block is installed under the sliding block. This limit block can ensure that the sliding block does not exceed the set range during the adjustment process, preventing equipment damage or instability caused by exceeding the limit. At the same time, the existence of the limit block effectively prevents the sliding block from losing control and enhances the safety of the equipment.

[0018] The cross-sectional shape of the limit block is rectangular, and a right-angled trapezoidal groove is provided at the lower end of the limit block, so that the inclined surface of the limit block corresponds to the inclined surface of the extrusion rod, thereby increasing the contact area between the limit block and the extrusion rod, thereby increasing the friction and making the sliding block more stable when sliding.

[0019] The cross-section of the stopper is rectangular, and a right-angled trapezoidal groove is provided at the lower end. This design allows the inclined surface of the stopper to correspond better to the inclined surface of the extrusion rod, increasing the contact area between the two. A larger contact area means more friction, which can provide a smoother sliding effect. Compared with the traditional design with a smaller contact surface, the increased contact area increases the friction between the two, making the sliding block more stable during the sliding process and reducing the vibration or instability during sliding. Strong friction can effectively prevent the sliding block from sliding unevenly or irregularly during movement. The design of increasing friction can effectively reduce the vibration generated during sliding and avoid excessive mechanical impact, which is particularly important in some occasions with high requirements for operating noise. The equipment runs more smoothly and generates less noise, which improves the comfort of the operating environment. Through precise design and reasonable friction control, the contact surface of the stopper and the extrusion rod evenly distributes force, thereby reducing local excessive wear. The moderate friction between the stopper and the extrusion rod helps to improve the durability of the components, extend the service life of the equipment, and reduce maintenance costs. Strong and uniform friction ensures that the slider will not deviate due to excessive sliding or unbalanced mechanical action. The design of the limit block effectively limits the range of motion of the slider, avoiding excessive or insufficient errors during adjustment and ensuring high precision of equipment operation.

[0020] The end of the conveying pipe close to the greenhouse is connected to the flow stabilizing tube, a cross is installed inside the flow stabilizing tube, a rotating rod is installed at the center of the cross, the rotating rod is installed with fan blades, and an L rod is installed in an array at the left end of the rotating rod to further stir the mixed liquid.

[0021] The cross is located inside the flow-stabilizing tube, and a rotating rod is installed in the center. This design can effectively increase the flow and mixing of the liquid in the conveying pipe. The movement of the rotating rod will drive the fan blades to rotate, thereby enhancing the stirring effect of the liquid and making the liquid mix more evenly. This is crucial for the distribution of liquid fertilizers, spray liquids or water in greenhouses, ensuring that the materials do not precipitate or stratify during the transportation process, thereby ensuring the consistency and stability of the spraying effect. The setting of the flow-stabilizing tube is mainly used to stabilize the flow of liquid and avoid excessive or unstable flow rates during transportation. The rotating rod increases the stirring effect of the liquid by driving the fan blades to rotate. By enhancing the fluidity of the liquid, the rotation of the fan blades helps to fully mix the components in the liquid, thereby improving the mixing efficiency and uniformity of the liquid. The array of L rods is installed at the left end of the rotating rod to further enhance the stirring force. The L rod increases the area and range of liquid stirring by cooperating with the rotating rod, so that the liquid can be more fully mixed in the flow-stabilizing tube. The design of the L rod increases the tumbling and stirring frequency of the liquid, which helps to stir the liquid more efficiently and prevent the accumulation of sediment. The liquid can be fully stirred during the transportation process, ensuring the uniformity of the liquid and the spraying effect. Since the liquid is constantly stirred and flows in the flow-stabilizing tube, the substances in the mixed liquid will not precipitate or agglomerate, which is crucial for the use of solutions that need to be mixed. Full stirring can prevent solid particles from agglomerating or settling, ensuring that the mixed liquid can maintain uniform quality during transportation and use, and avoiding clogging of pipes or spraying equipment.

[0022] A motor is installed on the side of the delivery pipe, and a rotating gear is installed on the front end of the motor. An adjusting gear is installed in meshing with the rotating gear, and the inner wall of the adjusting gear is set as a gear. An expansion gear is installed in the internal array of the adjusting gear, and the expansion gear is meshed with the adjusting gear. An expansion rod is installed coaxially with the expansion gear, and an expansion sheet is installed on the side of the expansion rod. The cross-sectional shape of the expansion sheet is elliptical to facilitate the flow of liquid. A baffle is installed on the other end of the expansion rod, and a bifurcated pipe is connected to the left side of the flow stabilizing pipe, and a shunt pipe is connected between the baffle and the cross.

[0023] The liquid flow rate is adjusted by rotating the gear and meshing it with the adjusting gear, and then adjusting the expansion gear inside the gear. The design of the expansion gear can control the movement of the expansion rod, and the expansion rod drives the expansion sheet to change the flow channel of the liquid, thereby accurately controlling the liquid flow. This can ensure that the liquid is evenly distributed at a predetermined flow rate during the transportation process, avoid the instability of the water flow caused by too fast or too slow flow rate, and ensure the precise adjustment of the equipment. The cross-section of the expansion sheet is elliptical, which helps the liquid flow more smoothly and reduces the disturbance and pressure fluctuations generated when the liquid flows. The elliptical expansion sheet can effectively guide the liquid to flow in the flow-stabilizing tube, maintain the stability of the flow, and prevent the liquid from having excessive turbulence or unevenness, thereby improving the stability and efficiency of liquid transportation. The motor drives the rotating gear, which in turn drives the movement of the adjusting gear, the expansion gear and the expansion rod, so that the adjustment of the liquid flow rate can be automatically controlled. In this automated way, the flow rate of the liquid can be accurately adjusted. The elliptical expansion sheet not only optimizes the path of the liquid flow, but also reduces the resistance of the liquid during the transportation process. The reduction of fluid resistance can reduce the energy consumption of the pumping equipment and improve the working efficiency of the equipment. At the same time, smoother fluid flow also means less noise caused by poor fluid flow, improving the comfort of the working environment. The design of the baffle and cross effectively controls the flow direction and distribution of the liquid through the diverter pipe, reducing the turbulence in the liquid flow process. The stable flow direction reduces the intense friction of the various components in the equipment, reduces the wear of the equipment, and thus extends the service life of the equipment.

[0024] The beneficial effects of the present invention are as follows: 1. The mutual meshing design between the transmission bevel gear, the reverse bevel gear and the driven bevel gear ensures the precise transmission of power. In particular, the diameter of the gear on the left side of the transmission bevel gear matches that of the transmission gear, so that the transmission kinetic energy at both ends is consistent, effectively avoiding equipment damage or instability caused by uneven speed, which significantly improves the stability and service life of the equipment.

[0025] 2. The cross-section of the rotating block is in the shape of a "comb", which can effectively increase the contact area between the rotating block and the expansion piece, and form a uniform extrusion effect during the rotation process, which can better dock with the expansion piece and provide a stable extrusion force to ensure the efficient operation of the expansion piece, avoiding functional failure or insufficient extrusion due to uneven contact, and the rotating block adopts a counterclockwise arrangement design, which makes the contact between the rotating block and the expansion piece more stable during movement, preventing the rotating block from getting stuck or not being able to rotate smoothly.

[0026] 3. The cross section of the expansion piece is elliptical, which helps the liquid flow more smoothly and reduces the disturbance and pressure fluctuations caused by the liquid flow. The elliptical expansion piece can effectively guide the liquid to flow in the flow-stabilizing tube, maintain the stability of the flow, and prevent excessive turbulence or unevenness of the liquid, thereby improving the stability and efficiency of liquid transportation.

DETAILED DESCRIPTION

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

At the same time, the motor 52 drives the gear to rotate and drives the expansion piece 525 to rotate, thereby adjusting the liquid flow rate inside the bifurcation pipe 53 and the diversion pipe 54.

[0032] The liquid flow driving mode effectively reduces manual operation, improves work efficiency, and ensures the smooth operation of each link. The equipment accurately controls the distribution of fertilizer in the regulating cylinder 48 through the forward and backward movement of the sliding block 482, ensuring that the fertilizer always maintains a reasonable amount during the transportation to the pepper plants. At the same time, the stirring rod 465 and the stirring plate 466 cooperate with the rotation of the bevel gear to effectively break up the fertilizer, promote the uniform mixing of fertilizer and soil, and avoid fertilizer agglomeration or pipeline blockage. The design of the flow stabilizing tube 5 helps to stabilize the flow of liquid, avoid drastic fluctuations in flow rate, and ensure that the spraying equipment remains stable during operation, thereby improving the spraying accuracy and avoiding insufficient or wasteful irrigation due to unstable flow rate. The motor 52 drives the gear to rotate and adjusts the liquid flow rate in the bifurcated tube 53 and the diverter tube 54, so that the equipment can flexibly adjust the intensity and range of liquid spraying according to demand to meet the needs of different crops or growth stages, thereby improving the flexibility of greenhouse management. The equipment not only has the functions of automatic spraying and fertilizer delivery, but also integrates the functions of fertilizer mixing and breaking up, avoiding the problem of fertilizer deposition or agglomeration, and improving the efficiency and stability of the overall equipment. Through stable liquid flow and precise fertilizer and liquid spraying control, it reduces the workload of farmers and makes greenhouse management more intelligent and convenient.

[0033] like Figure 3 , 4 , 5, 6, 7 and 8, the storage chamber 4 includes a closed chamber 41, a rotating rod 42, a conveyor belt 43, a transmission bevel gear 44, a reverse bevel gear 45, a driven bevel gear 46, a support cylinder 47, an adjustment cylinder 48 and a connecting pipe 49, the conveying pipe 3 is provided with a sealed chamber, a rotating rod 42 is provided inside the closed chamber 41, a blade 421 is provided on the side of the rotating rod 42, a transmission gear 422 is provided on the left end of the rotating rod 42, a conveyor belt 43 is provided on the right end of the rotating rod 42, a transmission bevel gear 44 is provided above the conveyor belt 43, a transmission bevel gear 44 is provided above the transmission gear 422, and a transmission bevel gear 44 is provided on the left end of the transmission bevel gear 44. The side is a gear structure, the diameter of the left gear of the transmission bevel gear 44 is the same as the diameter of the transmission gear 422, and the left gear of the transmission bevel gear 44 is meshed with the transmission gear 422, which can better make the transmission kinetic energy of the gear and the two ends of the conveyor belt 43 the same, avoiding the damage of the mechanism caused by excessive speed on one side, and a driven bevel gear 46 is meshed and installed between the transmission bevel gear 44 and the reverse bevel gear 45, and a supporting cylinder 47 is installed on the periphery of the driven bevel gear 46, and an adjusting cylinder 48 is installed on the upper end of the driven bevel gear 46, and a connecting pipe 49 is installed at the lower end of the adjusting cylinder 48, and the other end of the connecting pipe 49 is connected to the conveying pipe 3.

[0034] The precise meshing design between the transmission bevel gear 44, the reverse bevel gear 45 and the driven bevel gear 46 ensures the stable transmission of power. In particular, the precise matching of the diameter of the gear on the left side of the transmission bevel gear 44 and the transmission gear 422 ensures the consistent kinetic energy transmission at both ends, avoiding equipment failure or instability caused by uneven rotation speed. This optimized design significantly improves the stability and service life of the equipment. Through the reasonable design of the adjustment cylinder 48 and the connecting pipe 49, the fertilizer can be accurately transported from the adjustment cylinder 48 to the delivery pipe 3. This structure effectively controls the flow of fertilizer, ensures that the fertilizer is applied more evenly and accurately, thereby improving the fertilization effect and avoiding waste. The support cylinder 47 on the periphery of the driven bevel gear 46 enhances the stability of the entire transmission equipment, avoiding loosening or damage of components caused by uneven load or vibration generated during high-speed operation. The design of the support cylinder 47 makes the overall structure more solid and the working process more stable. The mechanical transmission structure of the present invention significantly reduces the burden on mechanical components through the precise meshing of gears and transmission synchronization. The closed chamber 41 installed on the conveying pipe 3 effectively prevents leakage of liquid or fertilizer, improves the safety and reliability of the equipment, and avoids external pollution or impurities from entering the conveying equipment.

[0035] like Figure 4 , 5 As shown in , 6, and 8, a limit ring 461 is provided above the driven bevel gear 46, and a fixed column 462 is installed in an array inside the limit ring 461, and a rotating block 463 is installed on the fixed column 462, and a tension spring 464 is clamped on the upper end of the rotating block 463, and the other end of the tension spring 464 is clamped on the driven bevel gear 46, and a stirring rod 465 is installed in an array on the upper end side of the driven bevel gear 46, and a stirring plate 466 is installed at one end of the outer periphery of the stirring rod 465, and the cross-sectional shape of the stirring plate 466 is arc-shaped, and the arc-shaped stirring plate 466 can better grind and clean the inner wall of the adjusting cylinder 48.

[0036] By setting a limit ring 461 above the driven bevel gear 46, and installing a fixed column 462 and a rotating block 463 inside the limit ring 461, a stable rotating device is formed. The rotating block 463 is connected to the driven bevel gear 46 through a tension spring 464 to ensure that the force is evenly distributed during the rotation process, avoiding excessive wear or vibration caused by uneven power, thereby improving the stability and service life of the device. The tension spring 464 provides a damping effect through its elastic properties, reducing the vibration and impact force that may be generated during the movement. This design not only reduces the wear of mechanical parts, but also improves the durability of the equipment, ensuring that the equipment maintains efficient working performance during long-term use. The cooperation of the stirring rod 465 and the stirring plate 466 with the driven bevel gear 46 makes the stirring process more uniform. The arc-shaped cross-section design of the stirring plate 466 has significant advantages, which can better fit the inner wall of the regulating cylinder 48, improve the stirring effect, and ensure that the fertilizer or liquid substance is fully mixed and evenly distributed in the regulating cylinder 48. In addition, the arc-shaped stirring plate 466 can also effectively clean the inner wall of the regulating cylinder 48, avoid the residue or agglomeration of fertilizer or liquid substances, and thus prevent the pipe from being blocked. The stirring plate 466 not only helps to mix the fertilizer, but also cleans the inner wall of the regulating cylinder 48 through its arc-shaped design. This design reduces the need for manual cleaning, enables the equipment to operate more efficiently, reduces maintenance workload, and reduces the risk of equipment failure. The cooperation between the rotating block 463 and the tension spring 464 makes the transmission of force more uniform and controllable, helps to avoid equipment damage or performance degradation caused by uneven force distribution, and further enhances the reliability of the equipment. Through the limiting effect of the limit ring 461, the rotating block 463 can rotate within a specific range, avoiding potential damage that may be caused by excessive movement.

[0037] like Figure 5 and 6 As shown, the cross-sectional shape of the rotating block 463 is a "comma" shape, and the rotating block 463 is arranged counterclockwise, which can better squeeze the support piece 471 during rotation to prevent the rotating block 463 from getting stuck during rotation. A rotating column 4631 is installed on the upper end of the rotating block 463 for convenient support. The rotating column 4631 is used to reduce friction during rotation and squeeze the support piece 471 more smoothly.

[0038] The cross-section of the rotating block 463 is designed to be in the shape of a "comb", which effectively increases the contact area between the rotating block 463 and the opening piece 471, and forms a uniform extrusion effect during the rotation process, so that it can better dock with the opening piece 471, provide a stable extrusion force, thereby ensuring the efficient operation of the opening piece 471, and avoiding functional failure or insufficient extrusion due to uneven contact. The rotating block 463 adopts a counterclockwise arrangement design, which optimizes the distribution of force during the rotation process, makes the contact between the rotating block 463 and the opening piece 471 more stable, and prevents the rotating block 463 from getting stuck or not rotating smoothly. A rotating column 4631 is installed at the upper end of the rotating block 463, and the function of the rotating column 4631 is to reduce the friction between the rotating block 463 and other components during the rotation process. This enables the rotating block 463 to rotate more smoothly, reduces the energy loss caused by friction, and also reduces mechanical wear. The use of the rotating column 4631 helps to improve the operating efficiency of the equipment and extend its service life. The rotating column 4631 reduces friction and resistance, making the extrusion between the rotating block 463 and the opening piece 471 smoother and more efficient. By optimizing power transmission, the energy consumption of the entire equipment is reduced, and the equipment exhibits higher efficiency and lower energy consumption during operation, saving energy and improving work efficiency. Due to the "teasing"-shaped cross-section and the counterclockwise arrangement design, the cooperation between the rotating block 463 and the opening piece 471 is smoother, avoiding the jamming phenomenon. This design significantly reduces the risk of equipment failure during operation and enhances the reliability and durability of the equipment. Since the rotating column 4631 effectively reduces friction, the contact and movement of the rotating block 463 with other components are smoother, further reducing wear and energy consumption. This not only improves the long-term operating efficiency of the equipment, but also reduces the frequency of repairs and replacement of parts, thereby reducing maintenance costs.

[0039] like Figure 5 , 6 As shown in Figure 7, the upper end of the support tube 47 is set to be disc-shaped, and two expansion pieces 471 are installed inside the disc-shaped interior of the upper end of the support tube 47. The cross-section of the expansion piece 471 is in the shape of an inferior arc, which can better adapt to the extrusion of the rotating block 463 and increase the friction between the rotating block 463 and the expansion block. An extrusion rod 472 is installed on the side of the expansion piece 471, and one end of the outer periphery of the extrusion rod 472 is set to be an inclined surface, which can more smoothly slide the limit block 483 on the sliding block 482.

[0040] The cross section of the spreading piece 471 is designed to be an inferior arc shape, which can better adapt to the extrusion of the rotating block 463. Compared with the traditional flat or circular design, the inferior arc shape can form a larger contact area when subjected to force, thereby enhancing the friction between the rotating block 463 and the spreading piece 471. The role of increasing the friction is to ensure that the equipment will not slip during the rotation process, thereby providing a stable extrusion effect and preventing unstable operation due to insufficient friction. The upper end of the support cylinder 47 is designed to be a disc shape. This structure can provide more uniform support and provide sufficient space to install two spreading pieces 471. The disc shape allows the spreading piece 471 to move freely within a larger range, improves the uniformity of extrusion, and ensures accurate processing of materials. One end of the extrusion rod 472 is designed to be an inclined surface, which can slide the limit block 483 on the sliding block 482 more smoothly. The inclined surface design reduces the resistance during sliding, making the sliding process smoother and smoother, thereby improving the accuracy of the operation and the overall performance of the equipment. At the same time, the inclined surface helps to evenly distribute the force applied to the limit block 483, avoiding the wear or jamming of components caused by uneven force. By increasing the friction between the rotating block 463 and the opening piece 471, better stability can be provided during the rotation process to prevent slippage or incoordination between components. The inclined surface design of the extrusion rod 472 ensures that the limit block 483 on the sliding block 482 slides smoothly, further reducing friction and vibration, making the entire device more stable during operation. The inclined surface design helps to reduce jamming, ensure that the limit block 483 can slide smoothly, and avoid the problem of equipment jamming caused by excessive friction or poor design, thereby enhancing the continuous working ability of the equipment, reducing downtime, and improving the reliability of the equipment. The stronger friction between the opening piece 471 and the rotating block 463, as well as the inclined surface design of the extrusion rod 472, effectively reduce unnecessary impact and friction loss between components. Reasonably designed friction helps to reduce wear during the operation of the equipment, extend the service life of each component, and thus reduce maintenance costs.

[0041] like Figure 6 , 7 As shown in 8, a sliding groove 481 is provided at the lower end of the adjusting cylinder 48 on the driven bevel gear 46, and the sliding groove 481 is composed of a semicircular shape at the front end and a rectangular shape at the rear end. A sliding block 482 is slidably installed inside the sliding groove 481, and the sliding block 482 is composed of a semicircular shape at the front end and a rectangular shape at the rear end, and a rectangular groove is provided in the middle of the sliding block 482, and a limiting block 483 is installed under the sliding block 482, and a restoring spring 484 is clamped at the rear end of the sliding block 482, and the other end of the restoring spring 484 is clamped on the adjusting cylinder 48.

[0042] The sliding groove 481 is composed of a semicircular part at the front end and a rectangular part at the rear end, and the front and rear shapes of the sliding block 482 match it. This design ensures that the sliding block 482 can move smoothly in the sliding groove 481, avoids the jamming phenomenon, makes the sliding process more stable and efficient, and thus improves the stability of the equipment. The combined design of the sliding groove 481 and the sliding block 482 enables the sliding block 482 to obtain a larger contact area and ensure smooth sliding during the adjustment process. The rear end of the sliding block 482 is connected to the recovery spring 484, and the function of the recovery spring 484 is to ensure that the sliding block 482 can automatically return to the initial position after the operation is completed, avoiding the stagnation or deviation of the sliding block 482 during the adjustment process. The recovery spring 484 provides an automatic reset function, which helps to ensure the consistency of each operation and avoid adjustment errors caused by improper human operation. A limit block 483 is installed below the sliding block 482, and the limit block 483 can ensure that the sliding block 482 does not exceed the set range during the adjustment process, preventing equipment damage or equipment instability due to exceeding the limit.

[0043] like Figure 7 and 8 As shown, the cross-sectional shape of the limit block 483 is rectangular, and a right-angled trapezoidal groove is provided at the lower end of the limit block 483, so that the inclined surface of the limit block 483 corresponds to the inclined surface of the extrusion rod 472, thereby increasing the contact area between the limit block 483 and the extrusion rod 472, thereby increasing the friction force and making the sliding block 482 more stable when sliding.

[0044] The cross section of the limit block 483 is rectangular, and a right-angled trapezoidal groove is provided at the lower end. This design enables the inclined surface of the limit block 483 to better match the inclined surface of the extrusion rod 472, increasing the contact area between the two. A larger contact area means stronger friction, thereby providing a smoother sliding effect. Compared with the traditional design with a smaller contact surface, the increased contact area increases the friction, making the sliding block 482 more stable during the sliding process and reducing vibration or instability. The enhanced friction can effectively prevent the sliding block 482 from sliding unevenly or irregularly during the movement, while reducing the vibration generated during sliding and avoiding excessive mechanical impact, which is particularly important in occasions with high requirements for operating noise. The equipment runs more smoothly and the noise is reduced, thereby improving the comfort of the operating environment. Through precise design and reasonable friction control, the contact surface of the limit block 483 and the extrusion rod 472 evenly distributes the force, reducing local excessive wear. Moderate friction helps to improve the durability of components, extend the service life of equipment, and reduce maintenance costs. Strong and uniform friction ensures that the sliding block 482 will not deviate due to excessive sliding or unbalanced mechanical effects, thereby improving the overall stability of the device. The design of the limit block 483 effectively limits the range of motion of the sliding block 482, avoiding excessive or insufficient errors during the adjustment process, and ensuring high precision in the operation of the device. The increased friction between the limit block 483 and the extrusion rod 472 improves the efficiency of force transmission and ensures that the sliding block 482 can run stably on the predetermined track. By providing additional friction, this design effectively enhances the structural stability of the device during long-term operation and reduces deviation or failure caused by external factors.

[0045] like Figure 2 , 9 As shown in Figure 10, one end of the conveying pipe 3 close to the greenhouse 2 is connected to the flow stabilizing tube 5, a cross 51 is installed inside the flow stabilizing tube 5, a rotating rod 511 is installed at the center of the cross 51, a fan blade 512 is installed on the rotating rod 511, and an L-rod 513 is installed in an array at the left end of the rotating rod 511, which can further stir the mixed liquid.

[0046] The cross 51 is located inside the flow-stabilizing tube 5, and a rotating rod 511 is installed in the center. This design effectively enhances the flow and mixing effect of the liquid in the delivery tube 3. The movement of the rotating rod 511 drives the fan blades 512 to rotate, thereby enhancing the stirring effect of the liquid and ensuring that the liquid is evenly mixed during the transportation process. This is very important for the distribution of liquid fertilizers, spray liquids or water in the greenhouse 2, and can prevent the material from precipitating or stratifying during the transportation process, ensuring the consistency and stability of the spraying effect. The setting of the flow-stabilizing tube 5 is mainly used to stabilize the flow of the liquid and avoid the phenomenon of excessive or unstable flow rate during the transportation process. Through the adjustment of the flow-stabilizing tube 5, the liquid flow rate can be ensured to be uniform, the formation of bubbles or pressure fluctuations can be reduced, the liquid stability can be maintained, and uneven flow can be prevented, thereby improving the spraying or delivery effect. The rotating rod 511 enhances the stirring effect of the liquid by driving the fan blades 512 to rotate. By enhancing the fluidity of the liquid, the rotation of the fan blades 512 helps to fully mix the components in the liquid and improve the mixing efficiency and uniformity. An array of L rods 513 is installed at the left end of the rotating rod 511 to further enhance the stirring force. The L rod 513 works in conjunction with the rotating rod 511 to expand the area and range of liquid stirring, so that the liquid is more comprehensively mixed in the flow-stabilizing tube 5. Compared with the traditional single stirring method, the L rod 513 design improves the frequency of liquid tumbling and stirring, helps to stir the liquid more efficiently, and prevents the accumulation of sediment. During the liquid transportation process, sufficient stirring ensures the uniformity and spraying effect of the liquid. Especially in agricultural production, the spraying of fertilizers or pesticides requires uniform liquid composition to avoid waste or poor effect caused by excessive or low local concentration. Through the synergistic effect of the rotating rod 511, the fan blades 512 and the L rod 513, the accuracy and efficiency of liquid mixing are improved, thereby improving the overall work efficiency. Since the liquid is constantly stirred and flowed in the flow-stabilizing tube 5, the substances in the mixed liquid will not precipitate or agglomerate, which is particularly important for solutions that need to be mixed. Sufficient stirring can prevent the aggregation or precipitation of solid particles, ensure that the mixed liquid maintains uniform quality during transportation and use, and avoid clogging pipes or spraying equipment.

[0047] like Figure 2 , 9As shown in 10, a motor 52 is installed on the side of the delivery pipe 3, and a rotating gear 521 is installed at the front end of the motor 52. An adjusting gear 522 is installed in meshing with the rotating gear 521, and the inner wall of the adjusting gear 522 is set as a gear. An expansion gear 523 is installed in the internal array of the adjusting gear 522, and the expansion gear 523 is meshed with the adjusting gear 522. An expansion rod 524 is installed coaxially with the expansion gear 523, and an expansion sheet 525 is installed on the side of the expansion rod 524. The cross-sectional shape of the expansion sheet 525 is elliptical to facilitate the flow of liquid. A baffle 526 is installed on the other end of the expansion rod 524. A bifurcated tube 53 is connected to the left side of the flow stabilizing tube 5, and a shunt tube 54 is connected between the baffle 526 and the cross 51.

[0048] The liquid flow rate is adjusted by rotating the gear 521 and meshing with the adjusting gear 522, and then adjusting the expansion gear 523 inside the gear 522. The design of the expansion gear 523 can accurately control the movement of the expansion rod 524, and the expansion rod 524 drives the expansion piece 525 to change the flow channel of the liquid, thereby realizing accurate control of the liquid flow. This design ensures that the liquid is evenly distributed at a predetermined flow rate during the transportation process, avoids unstable water flow caused by too fast or too slow flow rate, and ensures accurate adjustment of the equipment. The cross-section of the expansion piece 525 adopts an elliptical design, which helps the liquid flow more smoothly and reduces the disturbance and pressure fluctuations generated during the liquid flow process. The elliptical expansion piece 525 can effectively guide the liquid to flow in the steady flow tube 5, maintain the stability of the flow, and prevent the liquid from having too much turbulence or unevenness, thereby improving the stability and efficiency of liquid transportation. The motor 52 drives the rotating gear 521, which in turn drives the movement of the adjusting gear 522, the expansion gear 523 and the expansion rod 524 to realize the automatic adjustment of the liquid flow rate. Through this automated method, the liquid flow rate can be precisely controlled. The elliptical expansion piece 525 not only optimizes the liquid flow path, but also effectively reduces the resistance of the liquid during the delivery process. The reduction of fluid resistance can reduce the energy consumption of the pumping equipment and improve the working efficiency of the equipment.

[0049] In the working process of the present invention, when the staff sprays the peppers, the liquid flows from the inside of the conveying pipe 3, and the flowing liquid drives the rotating rod 42 to rotate through the blades 421, and the rotating rotating rod 42 drives the transmission gear 422 and the conveyor belt 43 to rotate, and the rotating transmission gear 422 and the conveyor belt 43 thereby drive the transmission bevel gear 44 and the reverse bevel gear 45 to rotate, and the rotating transmission bevel gear 44 and the reverse bevel gear 45 drive the driven bevel gear 46 to rotate, and the rotating driven bevel gear 46 undergoes centrifugal motion through the rotating block 463 inside the limiting ring 461, thereby expanding outward, and the expanded rotating block 463 is extended by itself and the rotating column 4631 is used to squeeze the expansion piece 471, thereby reducing the friction force of the rotating block 463 on the expansion piece 471, and by squeezing the expansion piece 471, the expansion piece 471 drives the squeezing rod 472 to move horizontally, and the horizontally moving squeezing rod 472 squeezes the limit block 483, so that the squeezing block moves horizontally, and the horizontally moving squeezing block drives the sliding block 482 to slide, and the sliding sliding block 482 can control the speed at which the fertilizer inside the regulating cylinder 48 enters the conveying pipe 3 through the connecting pipe 49, and the rotating driven bevel gear 46 squeezes the stirring rod 465 and the stirring plate 466 to break up the fertilizer to prevent the fertilizer from clogging the connecting pipe 49.

[0050] When the fertilizer enters the conveying pipe 3, the rotation of the fan blades 512 inside the flow stabilizing tube 5 drives the L rod 513 to rotate, so that the rotating L rod 513 stirs the mixture inside the flow stabilizing tube 5, and the rotating gear 521 is driven to rotate by the motor 52, and the rotating rotating gear 521 drives the adjusting gear 522 to rotate, and the rotating adjusting gear 522 drives the unfolding gear 523 to rotate, so that the rotating unfolding gear 523 drives the unfolding rod 524 and the unfolding sheet 525 to rotate, thereby adjusting the speed at which the liquid enters the bifurcated tube 53 and the diversion tube 54, and then adjusting the water output of the upper and lower water pipes to the peppers, so that the peppers can be watered accurately.
