Description

Technical Field

[0001] The invention relates to the technical field of agricultural intelligent equipment, and in particular to a rock wool planting pot loading machine and a loading method. Background Art

[0002] At present, the soilless cultivation mode using rock wool as a planting carrier has been widely used in the planting and production of vegetables and flowers. Rock wool has the advantages of light weight, good air permeability, strong water absorption, high porosity, strong drainage, etc., and it can stabilize the root system of crops very well, and is favored by major companies and growers.

[0003] Due to breeding needs, the cylindrical rock wool planting pot using the foam planting tray as a carrier needs to be made into a pit shape at one end to facilitate seed sowing and positioning. Therefore, it is currently necessary to manually distinguish the direction of the pit of the rock wool planting pot before placing it in the foam planting tray.

[0004] The rock wool planting pot tray loading machine in the prior art has the following technical problems:

[0005] Since rock wool is light and absorbs vibrations, the traditional vibrating disc feeding method can easily damage the rock wool planting pots, making it difficult to ensure the feeding effect and the feeding efficiency low, making it difficult to meet the requirements of assembly line operations. Summary of the invention

[0006] In view of the problems existing in the prior art, one of the objects of the present invention is to provide a rock wool planting pot loading machine which can improve the feeding effect, has high feeding efficiency and can meet the requirements of assembly line operations.

[0007] The second purpose of the present invention is to provide a method for installing a rock wool planting pot.

[0008] In order to achieve the above object, the present invention adopts the following technical solution:

[0009] A rock wool planting pot tray loading machine comprises a frame, on which a material box, a mold clamping device, a lifting push plate, a lifting drive device, a negative pressure suction device and a control device are arranged;

[0010] The material box is fixed to the frame and is used to store the rock wool planting pots to be loaded. The bottom is provided with a box bottom through hole matching the cross section of the jacking push plate;

[0011] The mold clamping device is located above the material box, and an upper semi-cylindrical groove is provided at the lower end;

[0012] The lifting push plate is slidably connected to the through hole at the bottom of the box body, and a lower semi-cylindrical groove is provided at the upper end;

[0013] The lifting drive device is connected to the lifting push plate, and is used to drive the lifting push plate to move up and down along the through hole at the bottom of the box body, so that the lower semi-cylindrical groove and the upper semi-cylindrical groove are sealed and butted to form a cylindrical cavity matching the cylindrical shape of the rock wool planting pot;

[0014] The negative pressure suction device is arranged on one side of the mold clamping device and is correspondingly connected to the cylindrical cavity, and is used to output the rock wool planting pot in the cylindrical cavity;

[0015] The control device is used to control the actions of the lifting drive device and the negative pressure suction device.

[0016] Furthermore, a scraper plate is provided between the lifting push plate and the clamping device, which is used to scrape away the rock wool planting pots that are not loaded into place on the lower semi-cylindrical groove.

[0017] Furthermore, a mold closing hole is provided at the top of the upper semi-cylindrical groove of the mold closing device, and the scraper plate is overlapped with the mold closing device and slides up and down in the mold closing hole; the scraper plate and the lifting push plate are connected with a linkage device, which is used to pull the scraper plate upward from the mold closing hole when the lifting push plate moves upward and docks with the mold closing device.

[0018] Furthermore, the clamping device is horizontally hinged to the material box, and a cantilever fixedly connected to the upper semi-cylindrical groove is provided on the side, the cantilever extends vertically downward and is fixedly connected to a triangular guide block with inclined surfaces at both ends, and a protrusion arranged corresponding to the triangular guide block is provided on the side of the lifting push plate, and the material box is provided with a box side through hole adapted to the moving path of the protrusion, and the protrusion is used to push the triangular guide block so that the clamping device drives the scraper plate to swing on the material box.

[0019] Furthermore, a posture adjustment device is provided between the triangular guide block and the upper semi-cylindrical groove, which is used to cooperate with the protrusion of the jacking push plate to adjust the mold clamping device from an inclined swinging posture to a vertical state.

[0020] Furthermore, the posture adjustment device includes a first rotating plate and a second rotating plate, the first rotating plate and the second rotating plate are vertically connected and are parallel to the cantilever, the first rotating plate is hinged to the upper semi-cylindrical groove and is arranged corresponding to the protrusion of the lifting push plate;

[0021] The posture adjustment device has a first state and a second state. In the first state, the protrusion of the lifting push plate pushes one side of the first rotating plate to rotate it and slide to the other side of the first rotating plate. In the second state, the protrusion of the lifting push plate pushes the other side of the first rotating plate to rotate it in the opposite direction. The cantilever limits the opposite rotation of the second rotating plate and cooperates with the protrusion of the lifting push plate to limit the first rotating plate and the second rotating plate to a vertical state.

[0022] Furthermore, the negative pressure suction device is connected to a vertical vacuum tube, in which a vacuum generator and a needle cylinder are arranged in sequence from top to bottom, the distance between the vacuum generator and the needle cylinder is greater than the height of one rock wool planting pot and less than the sum of the heights of two rock wool planting pots, a sorting disk is provided below the needle cylinder, the sorting disk is hinged to the frame, and a sorting groove adapted to the rock wool planting pot is provided in the sorting disk, the sorting groove is arranged corresponding to the needle cylinder, and a sorting sensor for judging whether the direction of the pit of the rock wool planting pot meets the requirements is provided at the bottom of the sorting groove, the sorting sensor is connected to a disk driving device, and the disk driving device is used to drive the sorting disk to rotate;

[0023] Pneumatic conveyors are respectively provided on both sides of the sorting plate for docking with the sorting grooves to output rock wool planting pots that meet the requirements, or to transport rock wool planting pots that do not meet the requirements back to the material box.

[0024] A method for loading a rock wool planting pot using a rock wool planting pot loading machine comprises the following steps:

[0025] The lifting driving device drives the lifting push plate to move upward along the through hole at the bottom of the box body, so that a plurality of rock wool planting pots stored in the material box are loaded into the lower semi-cylindrical groove at the upper end of the lifting push plate;

[0026] When the lifting push plate moves upward into position, the lower semi-cylindrical groove of the lifting push plate is sealed and docked with the upper semi-cylindrical groove of the clamping device to form a cylindrical cavity that matches the cylindrical shape of the rock wool planting pot;

[0027] A negative pressure suction device is connected to the cylindrical cavity to output the rock wool planting pot in the cylindrical cavity.

[0028] Further, the docking of the lifting push plate with the mold clamping device includes the following steps:

[0029] The protrusion of the lifting push plate pushes the triangular guide block of the mold clamping device upward, so that the mold clamping device drives the scraper plate from a vertical state to an inclined state, and the scraper plate swings on the material box to scrape out the crooked rock wool planting pot loaded on the lower semi-cylindrical groove;

[0030] When the protrusion of the lifting push plate passes over the triangular guide block upward, it touches the side of the first rotating plate from bottom to top, so that the first rotating plate and the second rotating plate rotate horizontally and gradually adjust from an inclined state to a vertical state. When the second rotating plate abuts against one side of the cantilever, the first rotating plate and the second rotating plate remain stationary under the pressure of the protrusion and the cantilever, limiting the mold clamping device to a stable vertical state.

[0031] The lifting push plate continues to move upward, and the scraper plate is pulled away from the upper semi-cylindrical groove through the linkage device; when the lifting push plate moves upward into position, the lower semi-cylindrical groove is sealed and docked with the upper semi-cylindrical groove.

[0032] Further, the rock wool planting pots are sorted when they are output, including the following steps:

[0033] The needle cylinder extends inside the vertical vacuum tube to form a blockage;

[0034] Make the rock wool planting pots fall downward into the vertical vacuum tube in turn and stay on the needle cylinder;

[0035] Use the vacuum generator to suck the second rock wool planting pot from bottom to top in the vertical vacuum tube;

[0036] The needle cylinder retracts, causing the rock wool planting pot resting on the needle cylinder to fall downward into the sorting groove of the sorting plate;

[0037] According to whether the sorting sensor at the bottom of the sorting groove is triggered by the rock wool planting pot falling into the sorting plate, it is judged whether the direction of the rock wool planting pot pit meets the requirements;

[0038] If it meets the requirements, the sorting disc is driven to rotate, and the sorting groove is connected through the pneumatic conveyor to output the rock wool planting pot in the sorting groove;

[0039] If it does not meet the requirements, the sorting disc is driven to rotate and docked with the sorting groove through the pneumatic conveyor to transport the rock wool planting pots in the sorting groove back to the material box.

[0040] In general, the present invention has the following advantages:

[0041] When in use, the lifting drive device starts working first, driving the lifting push plate to move upward along the through hole at the bottom of the box body. During the movement, several rock wool planting pots stored in the material box are loaded into the lower semi-cylindrical groove of the lifting push plate. When the lifting push plate moves upward into place, it seals and docks with the upper semi-cylindrical groove of the clamping device to form a cylindrical cavity that matches the cylindrical shape of the rock wool planting pot. Then the negative pressure suction device starts working to output the rock wool planting pot in the cylindrical cavity for loading. The present invention utilizes the gravity of the rock wool planting pot and the upward movement of the lower semi-cylindrical groove to achieve the natural loading of the rock wool planting pot on the lower semi-cylindrical groove, which can avoid damage to the rock wool planting pot, and utilizes the sealing docking of the lower semi-cylindrical groove and the upper semi-cylindrical groove to form a cylindrical cavity. The rock wool planting pot is transported by the negative pressure suction device, and the transportation speed is fast. Compared with the traditional vibrating disc feeding, it can improve the feeding effect and the feeding efficiency is high, which meets the requirements of assembly line operation.

[0063] The present invention will be described in further detail below.

[0064] like Figure 1 , Figure 5 , Figure 6 , Fig.10 , Fig.11 As shown, a rock wool planting pot tray loading machine includes a feeding mechanism 2, a sorting device 3 and a conveying line 1. The feeding mechanism 2 is used for loading rock wool planting pots 41, the sorting device 3 is used for judging the direction of the pits 411 of the rock wool planting pots 41 delivered by the feeding mechanism 2 and delivering the rock wool planting pots 41 that meet the requirements to the planting tray 42, and the conveying line 1 is used for delivering the planting tray 42 loaded with the rock wool planting pots 41.

[0065] The conveyor line 1 is arranged on a frame, the feeding mechanism 2 is arranged on the side of the conveyor line 1 , and the sorting device 3 is installed above the conveyor line 1 .

[0066] The feeding mechanism 2 includes a material box 21, a mold clamping device 24, a lifting push plate 22, a lifting drive device and a negative pressure suction device;

[0067] The material box 21 is fixed to the frame and is used to store the rock wool planting pots 41 to be loaded. The bottom is provided with a box bottom through hole 211 matching the cross section of the jacking push plate 22;

[0068] The mold clamping device 24 is located above the material box 21, and an upper semi-cylindrical groove 241 is provided at the lower end;

[0069] The lifting push plate 22 is slidably connected to the through hole 211 at the bottom of the box body, and a lower semi-cylindrical groove 221 is provided at the upper end;

[0070] The lifting drive device is connected to the lifting push plate 22, and is used to drive the lifting push plate 22 to move up and down along the bottom through hole 211 of the box body, so that the lower semi-cylindrical groove 221 and the upper semi-cylindrical groove 241 are sealed and docked to form a cylindrical cavity that matches the cylindrical shape of the rock wool planting pot 41;

[0071] The negative pressure suction device is arranged on one side of the mold clamping device 24 and is connected to the cylindrical cavity correspondingly, and is used to output the rock wool planting pot 41 in the cylindrical cavity;

[0072] The control device is used to control the actions of the lifting drive device and the negative pressure suction device.

[0073] When in use, the lifting drive device starts working first, driving the lifting push plate 22 to move upward along the bottom through hole 211 of the box body. During the movement, a number of rock wool planting pots 41 stored in the material box 21 are loaded into the lower semi-cylindrical groove 221 of the lifting push plate 22. When the lifting push plate 22 moves upward into position, it seals and docks with the upper semi-cylindrical groove 241 of the mold clamping device 24 to form a cylindrical cavity matching the cylindrical shape of the rock wool planting pot 41, and then the negative pressure suction device starts working to output the rock wool planting pot 41 in the cylindrical cavity for loading. The present invention utilizes the gravity of the rock wool planting pot 41 and the upward movement of the lower semi-cylindrical groove 221 to achieve natural loading of the rock wool planting pot 41 on the lower semi-cylindrical groove 221, and utilizes the sealed docking of the lower semi-cylindrical groove 221 and the upper semi-cylindrical groove 241 to form a cylindrical cavity, and transports the rock wool planting pot 41 through a negative pressure suction device. The transport speed is fast, and compared with traditional vibrating disc feeding, it can avoid vibration damage to the rock wool planting pot 41, improve the feeding efficiency and effect, and meet the requirements of assembly line operations.

[0074] Specifically, the main body of the material box 21 is a conical body that is narrow at the bottom and wide at the top. A long box side through hole 212 is provided on one side of the material box 21 to match the up and down movement path of the side protrusion 222 of the lifting push plate 22; the bottom is provided with a long box bottom through hole 211 with a guiding function that matches the cross-sectional size of the lifting push plate 22; a circular through hole 213 matching the diameter of the rock wool planting pot 41 is provided on one side of the upper part of the side plate of the material box 21, which is used to connect with the negative pressure suction device; a return flow hole 214 is also provided next to it, which is used to connect with the pneumatic conveyor 34 of the rock wool planting pot 41 whose direction does not meet the requirements of the return pit 411; a circular vent is provided on the other side; an oblique cut matching the diameter of the rotating shaft of the clamping device 24 is provided on the top of the side plate of the material box 21, and the clamping device 24 can swing on the oblique cut.

[0075] like Figure 2-Figure 4 , Figure 7As shown, the upper end of the lifting push plate 22 is provided with a lower semi-cylindrical groove 221 matching the diameter of the rock wool planting pot 41; the side of the lifting push plate 22 is provided with a protrusion 222 for pushing the mold clamping device 24, the protrusion 222 is penetrated through the box side through hole 212, and the upper and lower ends of the protrusion 222 are both set in a semicircular shape. The lifting drive device is an electric cylinder 26 fixed to the frame, and the electric cylinder 26 is connected to the lower end of the lifting push plate 22.

[0076] When the lifting push plate 22 moves upward from the bottom of the material box 21, sometimes some rock wool planting pots 41 are loaded crookedly on the lower semi-cylindrical groove 221. In this case, they need to be cleaned up before the lower semi-cylindrical groove 221 and the upper semi-cylindrical groove 241 can be docked. For this purpose, a scraper plate 23 is provided between the lifting push plate 22 and the clamping device 24 to scrape away the crooked rock wool planting pots 41 on the lower semi-cylindrical groove 221.

[0077] The scraper plate 23 can be in various forms, such as being arranged on one side above the material box 21. When the lower semi-cylindrical groove 221 rises, the scraper plate 23 is pushed out horizontally by the driving device to push away the crooked rock wool planting pot 41, and then the scraper plate 23 is retracted to avoid affecting the docking of the lower semi-cylindrical groove 221 and the upper semi-cylindrical groove 241. However, this structure requires an additional power source for the scraper plate 23, and requires precise control of the pushing out and retracting of the scraper plate 23, and the structure and control are relatively complicated.

[0078] like Fig. 9 As shown, a mold closing hole 2411 is provided on the top of the upper semi-cylindrical groove 241 of the mold closing device 24, and the scraper plate 23 is overlapped on the mold closing device 24 and slides up and down in the mold closing hole 2411; the scraper plate 23 and the lifting push plate 22 are connected with a linkage device 25, which is used to pull the scraper plate 23 upward from the mold closing hole 2411 when the lifting push plate 22 moves upward to dock with the mold closing device 24.

[0079] The clamping device 24 is horizontally hinged to the material box 21, and a cantilever 29 fixed to the upper semi-cylindrical groove 241 is provided on the side. The cantilever 29 extends vertically downward and is fixed to a triangular guide block 242 with inclined surfaces at both ends, which is arranged corresponding to the protrusion 222 on the side of the lifting push plate 22; the protrusion 222 is used to push the triangular guide block 242 so that the clamping device 24 drives the scraper plate 23 to swing on the material box 21.

[0080] like Figure 3As shown, the linkage device 25 includes a guide tube 251 provided on one side of the material box 21 and a traction rope 252 passing through the guide tube 251. The upper end of the guide tube 251 is located above the scraper plate 23, and the two ends of the traction rope 252 are respectively connected to the upper end of the scraper plate 23 and the lower end of the jacking push plate 22. When the jacking push plate 22 moves upward, it will pull the traction rope 252 in the guide tube 251. The length of the traction rope 252 needs to ensure that when the jacking push plate 22 reaches the swinging operation position of the scraper plate 23, the scraper plate 23 is tangent to the rock wool planting pot 41 that is correctly lying in the lower semi-cylindrical groove 221 of the jacking push plate 22.

[0081] The present invention arranges the scraper plate 23 in the upper semi-cylindrical groove 241, and links the lifting push plate 22 with the scraper plate 23 through the linkage device 25. There is no need to provide an additional power source for the scraper plate 23, and there is no need to accurately set the movement of the scraper plate 23. Only one power source (electric cylinder 26) is needed to complete the lifting and scraping of the rock wool planting pot 41 and form a closed rock wool planting pot 41 delivery pipeline. The structure is simpler and the operation is simpler.

[0082] like Figure 5 , Fig. 9 As shown, a posture adjustment device 28 is provided between the triangular guide block 242 and the upper semi-cylindrical groove 241 for cooperating with the protrusion 222 of the jacking push plate 22 to adjust the mold clamping device 24 from an inclined swinging posture to a vertical state.

[0083] Specifically, the posture adjustment device 28 includes a first rotating plate 281 and a second rotating plate 282, which are vertically connected and parallel to the cantilever 29. The first rotating plate 281 is hinged to the upper semi-cylindrical groove 241 and is arranged on one side of the protrusion 222 of the lifting push plate 22. One side of the cantilever 29 abuts against the second rotating plate 282 to limit the unidirectional rotation of the second rotating plate 282 and ensure that the cantilever 29 is in a vertical state.

[0084] In this embodiment, the negative pressure suction device is a pneumatic conveyor 34. When outputting the rock wool planting pot 41 in the cylindrical cavity, it is first transported to the vertical vacuum tube 272, and then passed through the sorting plate 33 to judge and sort the direction of the pit 411 of the rock wool planting pot 41, so as to output the rock wool planting pot 41 that meets the requirements into the planting plate 42.

[0085] like Figure 12-16 As shown, the sorting device 3 includes a vacuum generator 31, a needle cylinder 32 and a sorting plate 33 arranged below the needle cylinder 32 in sequence from top to bottom in a vertical vacuum tube 272. The distance between the vacuum generator 31 and the needle cylinder 32 is greater than the height of a single rock wool planting pot 41 and less than the sum of the heights of two rock wool planting pots 41. The sorting plate 33 is hinged to the frame and can rotate in a vertical plane.

[0086] The sorting disk 33 is evenly provided with four sorting grooves 331 matching the diameter of the rock wool planting pot 41 on the circumferential side wall. The sorting grooves 331 are arranged corresponding to the needle cylinders 32. The bottom of the sorting grooves 331 is respectively provided with a frustum matching the shape and size of the pit 411 of the rock wool planting pot 41. The bottom of the frustum is provided with a sorting sensor 362 for judging whether the direction of the pit 411 of the rock wool planting pot 41 meets the requirements. The sorting sensor 362 is connected to a disk driving device, and the disk driving device is used to drive the sorting disk 33 to rotate; pneumatic conveyors 34 are respectively provided on both sides of the sorting disk 33 for docking with the sorting grooves 331 to output the rock wool planting pots 41 that meet the requirements, or to convey the rock wool planting pots 41 that do not meet the requirements back to the material box 21.

[0087] The fixing seat of the needle cylinder 32 is provided with an air circuit installation hole matching the air circuit of the vacuum generator 31. The distance between the air circuit installation hole and the installation hole of the needle cylinder 32 needs to ensure that when the needle cylinder 32 is blocked under the lowest rock wool planting pot 41, the air circuit installation hole can be completely blocked by the second lowest rock wool planting pot 41.

[0088] Specifically, after the loading is completed, the pneumatic conveyor 34 transports the loaded rock wool planting pots 41 through the horizontal pipe 271 to the vertically arranged vertical vacuum tube 272. The rock wool planting pots 41 transported from the vertical vacuum tube 272 are blocked by the cylinder rod extended from the needle cylinder 32. At this time, the vacuum generator 31 works to adsorb and fix the second-to-last rock wool planting pot 41 below, and then the cylinder rod of the needle cylinder 32 retracts, and the previously blocked rock wool planting pots 41 fall freely downward into the sorting groove 331 of the sorting plate 33.

[0089] A bowl falling sensor 361 is provided below the needle cylinder 32 . When the rock wool planting bowl 41 falls freely downward into the sorting plate 33 , the bowl falling sensor 361 detects that the rock wool planting bowl 41 has fallen, and starts to activate the sorting sensor 362 .

[0090] If the sorting sensor 362 is triggered at this time, it means that the pit 411 of the rock wool planting pot 41 is downward and not in contact with the frustum in the sorting groove 331; if the sorting sensor 362 is not triggered, it means that the pit 411 of the rock wool planting pot 41 is upward and the bottom of the rock wool planting pot 41 falls on the frustum in the sorting groove 331.

[0091] The situation is judged based on the pits 411 of the rock wool planting pots 41. If it meets the requirements, the sorting disk 33 is driven to rotate through the disk driving device, docking with the pneumatic conveyor 34 on one side, and the rock wool planting pots 41 that meet the requirements are output to the planting disk 42 below through the bellows 35; each time a rock wool planting pot 41 is output, the outlet of the bellows 35 moves one grid, and each time a row of rock wool planting pots 41 is completed, the planting disk 42 is pushed forward one row until the entire planting disk 42 is filled with rock wool planting pots 41.

[0092] If it does not meet the requirements, the disc driving device drives the sorting disc 33 to rotate, docks with the pneumatic conveyor 34 on the other side, and conveys the rock wool planting pot 41 back to the material box 21 through the reflux hole 214 via the bellows 35.

[0093] A method for loading a rock wool planting pot using a rock wool planting pot loading machine comprises the following steps:

[0094] The lifting driving device drives the lifting push plate 22 to move upward along the bottom through hole 211 of the box body, so that the plurality of rock wool planting pots 41 stored in the material box 21 are loaded into the lower semi-cylindrical groove 221 at the upper end of the lifting push plate 22;

[0095] When the lifting push plate 22 moves upward into position, the lower semi-cylindrical groove 221 of the lifting push plate 22 is sealed and docked with the upper semi-cylindrical groove 241 of the clamping device 24, forming a cylindrical cavity that matches the cylindrical shape of the rock wool planting pot 41;

[0096] The negative pressure suction device is connected to the cylindrical cavity to output the rock wool planting pot 41 in the cylindrical cavity.

[0097] The present invention utilizes the gravity of the rock wool planting pot 41 and the upward movement of the lower semi-cylindrical groove 221 to achieve natural loading of the rock wool planting pot 41 on the lower semi-cylindrical groove 221, and utilizes the sealed docking of the lower semi-cylindrical groove 221 and the upper semi-cylindrical groove 241 to form a cylindrical cavity, and transports the rock wool planting pot 41 through a negative pressure suction device. Compared with traditional vibrating disc feeding, it can avoid damage to the rock wool planting pot 41, increase the conveying speed, improve the feeding effect, and meet the requirements of assembly line operations.

[0098] The docking of the lifting push plate 22 and the clamping device 24 includes the following steps:

[0099] The protrusion 222 of the lifting push plate 22 pushes the triangular guide block 242 of the mold clamping device 24 upward, so that the mold clamping device 24 drives the scraper plate 23 to change from a vertical state to an inclined state, and the scraper plate 23 swings on the material box 21 to scrape out the rock wool planting pots 41 that are not loaded in place on the lower semi-cylindrical groove 221;

[0100] When the protrusion 222 of the lifting push plate 22 passes over the triangular guide block 242 upward, it touches the side of the first rotating plate 281 from bottom to top, so that the first rotating plate 281 and the second rotating plate 282 rotate horizontally and gradually adjust from the inclined state to the vertical state. When the second rotating plate 282 abuts against one side of the cantilever 29, the first rotating plate 281 and the second rotating plate 282 remain stationary under the pressure of the protrusion 222 and the cantilever 29, and the mold clamping device 24 is restricted to a stable vertical state.

[0101] The lifting push plate 22 continues to move upward, and the scraper plate 23 is pulled away from the upper semi-cylindrical groove 241 through the linkage device 25; when the lifting push plate 22 moves upward into position, the lower semi-cylindrical groove 221 is sealed and docked with the upper semi-cylindrical groove 241.

[0102] The present invention can lift and scrape the rock wool planting pot 41 and form a closed rock wool planting pot 41 delivery pipeline through one power source, and has a simpler structure without the need to set up complex controls.

[0103] The rock wool planting pots 41 are sorted when they are output, including the following steps:

[0104] The needle cylinder 32 extends in the vertical vacuum tube 272 to form a blockage;

[0105] The rock wool planting pots 41 are sequentially dropped downward into the vertical vacuum tube 272 and stay on the needle cylinder 32;

[0106] Use the vacuum generator 31 to suck and stop the second rock wool planting pot 41 from bottom to top in the vertical vacuum tube 272;

[0107] The needle cylinder 32 retracts, causing the rock wool planting pot 41 resting on the needle cylinder 32 to fall downward into the sorting groove 331 of the sorting plate 33;

[0108] According to whether the sorting sensor 362 at the bottom of the sorting groove 331 is triggered by the rock wool planting pot 41 falling into the sorting plate 33, it is judged whether the direction of the pit 411 of the rock wool planting pot 41 meets the requirements;

[0109] If the requirements are met, the sorting plate 33 is driven to rotate, and the sorting groove 331 is docked through the pneumatic conveyor 34, and the rock wool planting pot 41 in the sorting groove 331 is output to the planting plate 42 through the bellows 35;

[0110] If it does not meet the requirements, the sorting disc 33 is driven to rotate and dock with the sorting groove 331 through the pneumatic conveyor 34 , and the rock wool planting pots 41 in the sorting groove 331 are transported back to the material box 21 through the bellows 35 .

[0111] The present invention utilizes the shape and light weight of the rock wool planting pot 41, uses a sorting disk 33 to distinguish the direction of the pit 411, uses a needle cylinder 32 to block and uses a vacuum generator 31 to suck and stop the rock wool planting pot 41, and combines the triggering of the sorting sensor 362 when the rock wool planting pot 41 falls freely, which can easily realize the determination of the direction of the pit 411 of the rock wool planting pot 41 in the vertical vacuum tube 272 one by one, and the operation is more convenient. After the direction of the rock wool planting pot 41 is distinguished, the bellows 35 is used for transportation, which not only has a fast transportation speed and can avoid damage to the rock wool planting pot 41, but also is conducive to alignment with the holes of the planting disk 42, improving the output efficiency and placement success rate.

[0112] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
