Description

Technical Field

[0001] This invention relates to the field of seedling equipment technology, specifically a three-dimensional seedling facility. Background Technology

[0002] In the field of modern agricultural seedling cultivation, vertical seedling facilities solve the pain points of traditional planar seedling cultivation, which are characterized by "efficient space utilization and automated maintenance," thanks to the dual advantages of "efficient space utilization and automated maintenance." They achieve full automation of the entire process from seedling feeding, cultivation, maintenance to cleaning, making them particularly suitable for large-scale seedling cultivation of vegetables, flowers, and other crops. They can increase seedling production by 3-5 times within a limited space while reducing the intensity of manual intervention.

[0003] After pesticides or fertilizers are sprayed onto the seedlings in the seedling trays, excess pesticides or fertilizers, along with the nutrient soil in the trays, will fall to the ground. This can deteriorate the environment inside the seedling nursery and make it difficult to maintain cleanliness. This is especially true when pesticides are sprayed, as the atomized pesticides quickly diffuse throughout the nursery, affecting air quality. To address this issue, we have introduced a vertical seedling system. Summary of the Invention

[0004] The purpose of this invention is to provide a three-dimensional seedling facility to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A three-dimensional seedling facility includes a seedling rack, with a tray loading and unloading rack at the front bottom of the seedling rack. The inner sides of the seedling rack and the tray loading and unloading rack are connected by a drive sprocket assembly and a conveyor chain. Several tray placement racks are connected between the two sets of conveyor chains, and the front bottom of the conveyor chain extends into the tray loading and unloading rack.

[0007] The bottom arc-shaped groove seat is fixed inside the loading and unloading rack of the cavitation tray. The upper arc-shaped groove seat is rotatably connected to the front end of the bottom arc-shaped groove seat by a drive component. The drive component is connected to the scraping component on the bottom arc-shaped groove seat by a clutch component.

[0008] When the seedling tray placement rack moves into the bottom arc-shaped groove, the drive component drives the upper arc-shaped groove to rotate and close above the bottom arc-shaped groove. The spray component on the upper arc-shaped groove sprays the seedlings on the seedling tray placement rack. Then, the drive component drives the upper arc-shaped groove to rotate in the opposite direction and open. At this time, the clutch component drives the scraping component to rotate and scrape away the impurities that fall into the bottom arc-shaped groove.

[0009] Preferably, the drive sprocket assembly includes several sets of first sprockets that are movably connected to the two sides inside the seedling rack in an alternating manner, a top front sprocket and a top rear sprocket that are movably connected to the top of the inside side of the seedling rack, an active sprocket that is movably connected to the rear of the inside side of the seedling rack, a guide sprocket that is movably connected to the front of the inside side of the seedling rack, and a bottom front sprocket that is movably connected to the inside side of the seedling tray loading and unloading rack.

[0010] The conveyor chain is connected between the drive sprocket, top rear sprocket, top front sprocket, guide sprocket, bottom front sprocket and several sets of first sprockets on the same side.

[0011] Preferably, a first servo motor is also fixed to the lower rear side of the seedling rack, and an active pulley is fixed to the output end of the first servo motor;

[0012] A drive shaft is fixed between the two sets of drive sprockets, and a driven pulley is fixed after one end of the drive shaft passes through the corresponding drive sprocket.

[0013] A belt connects the driving pulley and the driven pulley.

[0014] Preferably, the bottom arc-shaped groove seat is fixed in the loading and unloading rack of the cavity tray by a bracket, and two sets of symmetrically distributed fixing plates are provided at the front center of the bottom arc-shaped groove seat;

[0015] The drive assembly includes an upper rotating shaft and a second servo motor fixed between two sets of fixed plates, an upper gear fixed after the upper rotating shaft extends through the fixed plate, a lower gear fixed after the lower rotating shaft at the output end of the second servo motor extends through the fixed plate, and an intermediate gear movably connected to the middle of the outer side of the corresponding fixed plate.

[0016] The intermediate gear meshes between the upper gear and the lower gear;

[0017] The bottom arc-shaped groove seat is fixed with an upper connecting seat at the front end. The upper connecting seat has a threaded external cylinder that is threaded through the middle. The end of the upper rotating shaft is inserted into the center hole of the external threaded cylinder. The inner wall of the center hole of the external threaded cylinder is provided with a first protrusion. The first protrusion is engaged in a first groove on the surface of the end of the upper rotating shaft.

[0018] An L-shaped seat is fixed at the center of the bottom front end of the upper arc-shaped groove seat. The L-shaped seat is located between two sets of fixing plates and is fixed to the upper rotating shaft.

[0019] Preferably, a lower connecting seat is fixed to the front end of the bottom arc-shaped groove seat;

[0020] The clutch assembly includes a transmission assembly rotatably connected to the lower connecting seat, a clutch friction element connected to the end of the lower rotating shaft, and a toggle assembly connecting the clutch friction element and the external threaded cylinder.

[0021] The transmission assembly includes a transmission shaft passing through the lower connecting seat, a front transmission pulley fixed at the outer end of the transmission shaft, and a transmission friction disc fixed at the inner end of the transmission shaft.

[0022] The clutch friction component includes a clutch cylinder sleeved on the end of the lower rotating shaft, a clutch friction disc fixed on the outer side of the outer end of the clutch cylinder, and a bottom I-shaped ring seat fixed on the outer side of the inner end of the clutch cylinder. The inner wall of the clutch cylinder is provided with a second protrusion, which is inserted into a second groove on the surface of the end of the lower rotating shaft.

[0023] An upper I-shaped ring seat is fixed to the outer side of the outer end of the external threaded cylinder;

[0024] The actuating assembly includes a bottom ring fitted onto a bottom I-shaped ring seat, an upper ring fitted onto an upper I-shaped ring seat, and a connecting plate fixed between the bottom ring and the upper ring.

[0025] Preferably, the scraping assembly includes two sets of shafts symmetrically connected front and rear inside the bottom arc-shaped groove, scraper blades provided on the shafts, a synchronous gear fixed after one end of the shaft extends out of the bottom arc-shaped groove, a rear drive pulley fixed on the front synchronous gear, and a drive belt connecting the rear drive pulley and the front drive pulley.

[0026] The two sets of synchronous gears mesh with each other.

[0027] Preferably, the spraying assembly includes a liquid medicine pipe and a water and fertilizer pipe fixed at the top front and rear of the upper arc-shaped trough seat, and a plurality of sets of liquid medicine nozzles and water and fertilizer nozzles arranged in the bottom of the upper arc-shaped trough seat. The liquid medicine nozzles are connected to the liquid medicine pipes, and the water and fertilizer nozzles are connected to the water and fertilizer pipes.

[0028] The middle sections of the medicine pipe and the water and fertilizer pipe are respectively connected to medicine hoses and water and fertilizer hoses.

[0029] Compared with the prior art, the beneficial effects of the present invention are: the present invention, through the coordinated design of the bottom arc-shaped groove seat, the upper arc-shaped groove seat and the scraping component, blocks the source of pollution from the entire process of "collection-cleaning";

[0030] Enclosed collection prevents ground contamination: When the seedling tray holder moves into the bottom arc-shaped groove, the drive component rotates and closes the upper arc-shaped groove, forming a relatively enclosed spraying space (the bottom front sprocket is located directly above the bottom arc-shaped groove, ensuring precise alignment of the seedling tray holder). During spraying, excess pesticides, fertilizers, and loose potting soil fall directly into the bottom arc-shaped groove, rather than onto the ground, completely avoiding the problem of "pollutants contaminating the environment" in traditional seedling cultivation. This eliminates the need for frequent manual cleaning and significantly reduces environmental maintenance costs.

[0031] Automatic scraping enables instant cleaning: After spraying, the drive component opens the upper arc-shaped trough in the opposite direction. At this time, the clutch component activates the scraping component, and the scraper blades scrape the impurities (nutrient soil and residual liquid mixture) in the bottom arc-shaped trough to the bottom drain pipe for discharge. The entire cleaning process requires no manual intervention, and there are no impurities left in the bottom arc-shaped trough after cleaning, preventing the accumulation of pollutants and the growth of bacteria. This provides a clean environment for subsequent seedling cultivation and completely solves the pain point of "environmental degradation making it difficult to maintain the cleanliness of the seedling room".

Detailed Implementation

[0046] 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.

[0047] Example:

[0048] Please see Figures 1-13 The present invention provides a technical solution:

[0049] A vertical seedling facility includes a seedling rack 1 and a control console installed on the seedling rack 1. The bottom front end of the seedling rack 1 is provided with a tray loading and unloading rack 9. The inner sides of the seedling rack 1 and the tray loading and unloading rack 9 are connected by a drive sprocket assembly and a conveyor chain 3.

[0050] The control console includes a touch screen display and a PLC built into the touch screen display;

[0051] The seedling rack 1 serves as the main supporting structure of the entire facility, bearing key components in the seedling process. The tray loading and unloading rack 9 is located at the front bottom of the seedling rack 1, and the two are closely connected by a drive sprocket assembly and a conveyor chain 3. This layout creates a coherent seedling workflow, with the tray placement rack 8 moving cyclically between the seedling rack 1 and the tray loading and unloading rack 9, driven by the conveyor chain 3. From a space utilization perspective, the close integration of the two avoids wasting floor space and is suitable for efficient operation within a limited seedling space.

[0052] Several sets of tray placement racks 8 are connected between the two sets of conveyor chains 3, and the bottom front end of the conveyor chain 3 extends into the tray loading and unloading rack 9;

[0053] The seedling trays are moved into the seedling tray placement rack 8 on the seedling rack 1. The seedling tray placement rack 8 is in a cyclical operation mode along the conveyor chain 3, and the final operation cycle is controlled to be 45 minutes.

[0054] The seedling rack 1 is also equipped with a supplementary light 2; the supplementary light 2 is controlled by a PLC to complement the light received by the seedlings in the seedling trays; according to the operating cycle time of the seedling tray placement rack 8 on the conveyor chain 3, the supplementary light 2 is automatically controlled by the PLC to turn on or off according to the time nodes.

[0055] From a workflow perspective, the transfer of seedling trays between the seedling rack 1 and the seedling tray loading / unloading rack 9 allows for the orderly connection of seedling loading, cultivation, and unloading processes, thereby improving overall seedling efficiency.

[0056] The drive sprocket assembly includes several sets of first sprockets 4 that are movably connected to the inner sides of the seedling rack 1 in an alternating manner; a top front sprocket 30 and a top rear sprocket 29 that are movably connected to the top of the inner side of the seedling rack 1; a drive sprocket 5 that is movably connected to the rear of the inner side of the seedling rack 1; a guide sprocket 32 ​​that is movably connected to the front of the inner side of the seedling rack 1; and a bottom front sprocket 31 that is movably connected to the inner side of the seedling tray loading and unloading rack 9.

[0057] The conveyor chain 3 is connected to the drive sprocket 5, the top rear sprocket 29, the top front sprocket 30, the guide sprocket 32, the bottom front sprocket 31 and several sets of first sprockets 4 on the same side.

[0058] The bottom front sprocket 31 is located directly above the bottom arc-shaped groove seat 11. After the upper arc-shaped groove seat 10 gradually closes above the bottom arc-shaped groove seat 11, a relatively enclosed spray space is formed between the upper arc-shaped groove seat 10 and the bottom arc-shaped groove seat 11.

[0059] A first servo motor 6 is fixed to the lower rear side of the seedling rack 1, and an active pulley 13 is fixed to the output end of the first servo motor 6; a drive shaft 7 is fixed between the two sets of active sprockets 5, and a driven pulley 15 is fixed after passing through the corresponding active sprocket 5 at one end of the drive shaft 7; a belt 14 is connected between the active pulley 13 and the driven pulley 15.

[0060] The drive sprocket assembly is the core power transmission system that enables the movement of the seedling tray placement rack 8. Inside the seedling rack 1, on both sides, several sets of first sprockets 4 are distributed vertically and horizontally. They act as basic nodes in the transmission network, providing multi-point support and guidance for the conveyor chain 3, ensuring the stability of the conveyor chain 3 during operation, and preventing it from shifting or falling off.

[0061] The top front sprocket 30 and the top rear sprocket 29 are located at the front and rear positions of the top side inside the seedling rack 1. Together with the drive sprocket 5, the guide sprocket 32 ​​and the bottom front sprocket 31, they form a complete transmission path.

[0062] The PLC controls the operation of the first servo motor 6, thereby adjusting the speed of the drive sprocket 5. The drive sprocket 5 drives the conveyor chain 3 to rotate, and controls the conveyor chain 3 to run for one cycle of 45 minutes.

[0063] Driven by the first servo motor 6, the drive sprocket 5 begins to rotate, transmitting power to the drive shaft 7 via the belt 14, which in turn drives the drive sprocket 5 to rotate. The rotation of the drive sprocket 5 then sequentially drives the connected conveyor chain 3, causing the conveyor chain 3 to circulate along the trajectory formed by the various sprockets. Ultimately, this drives the seedling tray placement rack 8 to move smoothly between the seedling rack 1 and the seedling tray loading / unloading rack 9, realizing the positional change of seedlings at different seedling stages.

[0064] The bottom arc-shaped groove seat 11 is fixed inside the loading and unloading rack 9 of the caulking tray. The upper arc-shaped groove seat 10 is rotatably connected to the front middle of the bottom arc-shaped groove seat 11 by a drive assembly 12. The drive assembly 12 is connected to the scraping assembly 17 on the bottom arc-shaped groove seat 11 by a clutch assembly 16.

[0065] The bottom arc-shaped groove seat 11 is fixed in the tray loading and unloading rack 9 by a bracket 22. Two sets of symmetrically distributed fixing plates 24 are provided in the middle of the front end of the bottom arc-shaped groove seat 11.

[0066] The drive assembly 12 includes an upper rotating shaft 127 and a second servo motor 121 fixed between two sets of fixed plates 24, an upper gear 125 fixed after the upper rotating shaft 127 extends through and out of the fixed plate 24, a lower rotating shaft 123 at the output end of the second servo motor 121 extends through and out of the fixed plate 24 and is fixed to a lower gear 122, and an intermediate gear 124 movably connected to the middle of the outer side of the corresponding fixed plate 24.

[0067] The intermediate gear 124 meshes between the upper gear 125 and the lower gear 122;

[0068] The bottom arc-shaped groove seat 11 has an upper connecting seat 27 fixed at the front end. The upper connecting seat 27 has an external threaded cylinder 126 threaded through the middle. The end of the upper rotating shaft 127 is inserted into the center hole of the external threaded cylinder 126. The inner wall of the center hole of the external threaded cylinder 126 is provided with a first protrusion 1261. The first protrusion 1261 is engaged in the first slot 1271 on the end surface of the upper rotating shaft 127.

[0069] An L-shaped seat 23 is fixed at the center of the bottom front end of the upper arc-shaped groove seat 10. The L-shaped seat 23 is located between two sets of fixing plates 24 and is fixed to the upper rotating shaft 127.

[0070] The lower connecting seat 28 is fixed to the front end of the bottom arc-shaped groove seat 11;

[0071] The clutch assembly 16 includes a transmission assembly rotatably connected to the lower connecting seat 28, a clutch friction element connected to the end of the lower rotating shaft 123, and an actuating assembly 164 connected between the clutch friction element and the external threaded cylinder 126.

[0072] The transmission assembly includes a drive shaft that passes through the lower connecting seat 28, a front drive pulley 161 fixed at the outer end of the drive shaft, and a transmission friction disc 162 fixed at the inner end of the drive shaft.

[0073] The clutch friction component includes a clutch cylinder 165 sleeved on the end of the lower rotating shaft 123, a clutch friction disc 163 fixed on the outer side of the outer end of the clutch cylinder 165, and a bottom I-shaped ring seat 166 fixed on the outer side of the inner end of the clutch cylinder 165. A second protrusion 1631 is provided on the inner wall of the clutch cylinder 165, and the second protrusion 1631 is inserted into the second groove 1231 on the end surface of the lower rotating shaft 123.

[0074] An upper I-shaped ring seat 129 is fixed to the outer side of the outer end of the external threaded cylinder 126;

[0075] The actuating assembly 164 includes a bottom ring 1641 sleeved on the bottom I-shaped ring seat 166, an upper ring 1643 sleeved on the upper I-shaped ring seat 129, and a connecting plate 1642 fixed between the bottom ring 1641 and the upper ring 1643.

[0076] The scraping assembly 17 includes two sets of shafts 175 symmetrically connected front and rear inside the bottom arc-shaped groove seat 11, a scraper 174 provided on the shafts 175, a synchronous gear 171 fixed after one end of the shaft 175 extends out of the bottom arc-shaped groove seat 11, a rear drive pulley 172 fixed on the front synchronous gear 171, and a drive belt 173 connecting the rear drive pulley 172 and the front drive pulley 161.

[0077] The two sets of synchronous gears 171 mesh with each other.

[0078] The spray assembly includes a liquid medicine pipe 19 and a water and fertilizer pipe 18 fixed at the top front and rear of the upper arc-shaped trough 10, and several sets of liquid medicine nozzles 25 and water and fertilizer nozzles 26 arranged in the bottom of the upper arc-shaped trough 10. The liquid medicine nozzles 25 are connected to the liquid medicine pipe 19, and the water and fertilizer nozzles 26 are connected to the water and fertilizer pipe 18.

[0079] The middle sections of the pesticide pipe 19 and the water and fertilizer pipe 18 are respectively connected to a pesticide hose 20 and a water and fertilizer hose 21. The pesticide hose 20 and the water and fertilizer hose 21 are respectively connected to a pesticide pump and a water and fertilizer pump, which are controlled by a PLC to spray pesticide and water and fertilizer respectively.

[0080] Based on the operating cycle time of the cavity tray placement rack 8 on the conveyor chain 3, a PLC is used to automatically set a cycle timer for spraying and the spraying on / off time.

[0081] The liquid medicine pipe 19 and the water and fertilizer pipe 18 are fixed at the front and rear positions of the top of the upper arc-shaped trough seat 10. The liquid medicine and water and fertilizer are accurately sprayed onto the seedlings on the seedling tray placement rack 8 through the liquid medicine nozzle 25 and the water and fertilizer nozzle 26, so as to meet the nutritional and pest and disease control needs of the seedlings during their growth process.

[0082] The independent installation of the pesticide solution pipe 19 and the water and fertilizer pipe 18 in the spray assembly allows for precise control of the supply of pesticide solution and water and fertilizer according to the growth needs of the seedlings. At different stages of seedling growth, the needs for nutrients and pest and disease control vary. The independent pipe setup allows for separate control of parameters such as the flow rate and concentration of pesticide solution and water and fertilizer, achieving precise nutrient supply and pest and disease control.

[0083] The reasonable distribution of the liquid spray nozzles 25 and the water and fertilizer spray nozzles 26 at the bottom of the lower arc-shaped trough seat 10 ensures comprehensive spraying, covering every seedling on the seedling tray placement rack 8. This ensures that each seedling receives sufficient nourishment and protection, meeting its needs for water and nutrients at each growth stage. It provides ample material conditions for the healthy growth of seedlings, helps to cultivate robust and uniform seedlings, and improves the quality of seedling cultivation.

[0084] The scraping component 17 is installed inside the bottom arc-shaped groove 11. When the upper arc-shaped groove 10 is opened, the clutch component 16 drives the scraping component 17 to rotate, scraping away the impurities that fall into the bottom arc-shaped groove 11. The connection between the two ensures that impurities generated by spraying can be cleaned up in a timely manner after the spraying operation is completed during seedling cultivation, ensuring a clean seedling environment and providing good conditions for the healthy growth of seedlings.

[0085] When the seedling tray placement rack 8 moves into the bottom arc-shaped groove 11, the drive component 12 drives the upper arc-shaped groove 10 to rotate and close above the bottom arc-shaped groove 11. The spray component on the upper arc-shaped groove 10 sprays the seedlings on the seedling tray placement rack 8. Then, the drive component 12 drives the upper arc-shaped groove 10 to rotate in the opposite direction and open. At this time, the clutch component 16 drives the scraping component 17 to rotate and scrape the impurities that fall into the bottom arc-shaped groove 11.

[0086] After the spraying operation is completed, without manual intervention, the scraping component 17 automatically starts under the precise control of the clutch component 16 to clean impurities in the bottom arc-shaped groove 11. This automatic scraping mechanism not only reduces manual maintenance costs but also removes impurities in a timely manner, reducing the risk of bacterial growth and creating a clean and healthy growth environment for the seedlings. The design of the clutch component 16 allows the start and stop of the scraping component 17 to be closely coordinated with the spraying operation process, ensuring timely response when impurities need to be cleaned, while avoiding unnecessary operation at other times, saving energy and improving the overall operating efficiency and stability of the seedling facility.

[0087] Specifically, when using it:

[0088] When the seedling cultivation work begins, the first servo motor 6 starts operating. As the power source for the entire conveying system, the first servo motor 6 causes the drive pulley 13, which is fixed at its output end, to rotate. The drive pulley 13 is connected to the driven pulley 15 via a belt 14, causing the driven pulley 15 to also begin rotating. The rotation of the driven pulley 15 drives the drive shaft 7 to rotate synchronously, ultimately causing the drive sprocket 5 to start operating.

[0089] The rotation of the drive sprocket 5 becomes the direct driving force for the movement of the conveyor chain 3. The conveyor chain 3 is tightly meshed with the drive sprocket 5 and, driven by the drive sprocket 5, moves cyclically along the trajectory formed by the top rear sprocket 29, the top front sprocket 30, the guide sprocket 32, the bottom front sprocket 31, and several sets of first sprockets 4.

[0090] During the movement of the conveyor chain 3, the seedling tray placement rack 8 connected between the two sets of conveyor chains 3 moves accordingly, realizing the transfer of seedlings between the seedling rack 1 and the seedling tray loading and unloading rack 9.

[0091] When the seed tray placement frame 8 moves into the bottom arc-shaped groove seat 11 along with the conveyor chain 3, the spraying operation is initiated. At this time, the second servo motor 121 starts working, and its output end lower shaft 123 drives the lower gear 122 to rotate. The lower gear 122 meshes with the intermediate gear 124, and the intermediate gear 124 meshes with the upper gear 125. Through this gear transmission structure, the rotation of the lower shaft 123 is transmitted to the upper shaft 127.

[0092] The upper rotating shaft 127 is connected to the L-shaped seat 23 fixed at the center of the bottom front end of the upper arc-shaped groove seat 10. Therefore, the rotation of the upper rotating shaft 127 drives the upper arc-shaped groove seat 10 to rotate around the connection point at the center of the front end of the bottom arc-shaped groove seat 11, so that the upper arc-shaped groove seat 10 gradually closes above the bottom arc-shaped groove seat 11, forming a relatively closed spray space.

[0093] As the upper arc-shaped groove seat 10 gradually closes above the bottom arc-shaped groove seat 11, the upper rotating shaft 127 drives the external threaded cylinder 126 to rotate. Since the external threaded cylinder 126 is screwed to the upper connecting seat 27, the external threaded cylinder 126 moves along the upper rotating shaft 127 towards the upper gear 125. The external threaded cylinder 126 pushes the clutch friction member inward through the actuating assembly 164, causing the clutch friction member to move along the lower rotating shaft 123 towards the lower gear 122 until the clutch friction disc 163 of the clutch friction member disengages from the transmission friction disc 162 in the transmission assembly.

[0094] This causes the clutch assembly 16 to disengage the drive assembly 12 from the scraping assembly 17, so that the scraping assembly 17 stops rotating when the upper arc-shaped groove seat 10 gradually closes above the bottom arc-shaped groove seat 11.

[0095] Subsequently, the pesticide hose 20 and the water and fertilizer hose 21 are connected to external pesticide and water and fertilizer supply sources, respectively, introducing the pesticide and water / fertilizer into the pesticide hose 19 and water / fertilizer hose 18. Several sets of pesticide nozzles 25 and water / fertilizer nozzles 26 installed on the pesticide hose 19 and water / fertilizer hose 18 begin operating, evenly spraying the pesticide and water / fertilizer onto the seedlings on the seedling tray rack 8, meeting the seedlings' nutritional needs for growth and pest and disease control. After the pesticide or water / fertilizer is evenly sprayed onto the seedlings on the seedling tray rack 8, excess pesticide or water / fertilizer, along with the nutrient soil in the seedling trays, will fall down the bottom of the seedling tray rack 8 into the bottom arc-shaped groove 11.

[0096] After the spraying operation is completed, in order to keep the seedling environment clean, it is necessary to clean up the impurities generated during the spraying process.

[0097] At this time, as Figure 11 As shown, the second servo motor 121 reverses, driving the lower rotating shaft 123 to rotate in the opposite direction. Through the gear transmission structure of the drive assembly 12, the upper rotating shaft 127 drives the upper arc-shaped slot seat 10 to rotate in the opposite direction and open.

[0098] During this process, clutch assembly 16 begins to function.

[0099] The upper rotating shaft 127 drives the external threaded cylinder 126 to rotate. Since the external threaded cylinder 126 is screwed to the upper connecting seat 27, the external threaded cylinder 126 moves along the upper rotating shaft 127 to the end of the upper rotating shaft 127. The external threaded cylinder 126 pushes the clutch friction member outward through the actuating assembly 164, so that the clutch friction member moves along the lower rotating shaft 123 to the end of the lower rotating shaft 123 until the clutch friction disc 163 of the clutch friction member contacts the transmission friction disc 162 in the transmission assembly.

[0100] In this way, since the bottom I-shaped ring seat 166, which is fixed on the outer side of the inner end of the clutch cylinder 165, and the upper I-shaped ring seat 129, which is fixed on the outer side of the outer end of the external thread cylinder 126, are connected by the actuating component 164, when the lower rotating shaft 123 rotates, the clutch friction disc 163 and the transmission friction disc 162 are tightly engaged by the actuating component 164 to achieve power transmission.

[0101] When the lower rotating shaft 123 rotates, it will drive the clutch friction component to rotate. The clutch friction disc 163 and the transmission friction disc 162 are in close contact, which makes the transmission friction disc 162 rotate.

[0102] The transmission friction disc 162 is fixed on the transmission shaft, and the front transmission pulley 161, which is fixed on the outer end of the transmission shaft, rotates with the rotation of the transmission shaft.

[0103] The front drive pulley 161 is connected to the rear drive pulley 172 in the scraping assembly 17 via the drive belt 173, thereby driving the rear drive pulley 172 to rotate. The rear drive pulley 172 is fixed on the shaft 175, and the scraper 174 provided on the shaft 175 rotates with the rotation of the shaft 175, scraping away the impurities falling into the bottom arc-shaped groove 11, and scraping the dirt on the inner wall of the bottom arc-shaped groove 11 to the bottom of the bottom arc-shaped groove 11, ensuring the cleanliness of the bottom arc-shaped groove 11 and preparing for the next spraying operation.

[0104] The bottom of the arc-shaped groove 11 is also equipped with a drain pipe to facilitate the discharge of dirt and grime.

[0105] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
