Description

Technical Field

[0001] The invention relates to the technical field of soilless cultivation, in particular to a device for cultivating seedlings of traditional Chinese medicine soilless cultivation. Background Art

[0002] Hydroponics is a new type of soilless plant cultivation method, also known as nutrient solution culture. Its core is to directly immerse the roots of plants in nutrient solution. This nutrient solution can replace soil and provide plants with water, nutrients, oxygen and other growth factors, allowing plants to grow normally.

[0003] When hydroponically cultivating seedlings, a plurality of seedling trays with porous bottoms are usually floated in a seedling pool filled with nutrient solution. The seedling trays have a plurality of compartments for cultivating seedlings, and the plurality of seedling trays are arranged in an array in the seedling pool.

[0004] The Chinese invention patent with announcement number CN113785762B discloses a hydroponic device for floating seedling cultivation of Chinese cabbage, which has two limit plates, which are rotatably arranged in grooves opened on the left and right sides of the upper side of the seedling pool through a rotating shaft and a bearing; there are two limit adjustment mechanisms, which are respectively arranged in the left and right side walls of the seedling pool; motor No. 1 is fixedly arranged on the bottom surface of the seedling pool through a motor bracket, and the output shaft of motor No. 1 is rotatably penetrated through the bottom surface of the seedling pool through a sealed bearing; there are several stirring blades, which are fixedly arranged on the output shaft of motor No. 1 located inside the seedling pool with equal fillets; the lifting limit mechanism is arranged on the lower side of the floating seedling tray; the cabbage root cutting mechanism is arranged in the middle of the lifting limit mechanism; the uniformity of the added nutrients and the medicinal solution is ensured, and the consistency of the cabbage maturation cycle is ensured. At the same time, the seedling tray can be limited, which is convenient for harvesting and automatic removal of the cabbage roots.

[0005] Although the above patent solves the problem of uneven nutrient solution components and difficulty in harvesting and picking, during the seedling period, it is usually necessary to remove dead seedlings, re-sow, observe the growth of seedlings, etc. Workers usually take out multiple seedling trays in the same row on one side of the seedling pool, and then put the multiple seedling trays back one by one. When the seedling pool is wide, the seedling trays far away from the workers need to be pulled in front of the workers with the help of tools, which is inconvenient to operate. In addition, since the seedling trays are directly placed in the seedling pool, when the seedling pool is wide, the seedling trays far away are easily stuck with the adjacent seedlings during the placement process.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-8 The present invention describes the above technical solution in detail through the following embodiments:

[0046] A Chinese medicine soilless cultivation seedling equipment, comprising a seedling pool 1 and a seedling tray 2, wherein a longitudinal rod 20 is provided in the seedling pool 1 along the longitudinal direction of the width, and a plurality of longitudinal rods 20 are arranged at equal intervals in the transverse direction of the length direction of the seedling pool 1, and the plurality of longitudinal rods 20 separate the upper layer of the seedling pool 1 into N row tray areas 3, and a plurality of seedling trays 2 in the row tray area 3 are arranged in a longitudinal row, and the longitudinal row is provided with N-1;

[0047] A tray rack 4 is provided above the seedling pool 1, and a tray taking port 5 for taking out the seedling tray 2 in the seedling pool 1 is provided on the tray rack 4. Travel mechanisms 6 are provided at both ends of the tray rack 4 in the longitudinal direction, and the tray rack 4 is moved back and forth laterally by means of the travel mechanisms 6.

[0048] Both sides of the tray area 3 are rotatably provided with feed screws 7 arranged longitudinally, and both sides of the seedling tray 2 are longitudinally provided with multiple feed columns 8 at equal intervals, and the spacing between adjacent feed columns 8 on the same side is the same as the pitch of the feed screw 7;

[0049] Both ends of the feed screw 7 that penetrates the seedling pool 1 are provided with driven column gears 10, and the feed screw 7 drives the seedling tray 2 to move longitudinally with the help of the feed column 8;

[0050] Both ends of the tray rack 4 are provided with a feeding drive mechanism 9, which is sequentially connected with the driven column gears 10 on both sides of the plurality of tray row areas 3 during the lateral movement of the tray rack 4, and the feeding drive mechanism 9 drives the feeding screw 7 to rotate by means of the driven column gears 10;

[0051] A tray placing rack 11 is provided on one lateral side of the tray feeding rack 4, and the tray placing rack 11 is provided with a tray placing opening 12 running through the top and bottom thereof, and movable support plates 13 are rotatably provided on both lateral sides of the tray placing opening 12, and slide grooves 14 for cooperating with the movable support plates 13 are provided on both lateral sides of the seedling tray 2;

[0052] The tray rack 11 is provided with a slat drive mechanism 15 for driving the movable support plate 13 to swing up and down. The movable support plate 13 disengages from the slide slot 14 during the downward swinging process, so that the multiple seedling trays 2 on the movable support plates 13 on both sides fall into the seedling pool 1 below through the tray placement opening 12.

[0053] The worker is located at the operation side of the seedling pool 1, and works from one end of the seedling pool 1 where the idle tray area 3 is located to the other end. The travel mechanism 6 actively drives the tray rack 4 and the tray rack 11 to move, or the tray rack 4 and the tray rack 11 are pushed by the worker with the help of the travel mechanism 6. When the tray opening 12 of the tray rack 11 is aligned with the idle tray area 3, and the tray taking opening 5 of the tray rack 4 is aligned with the second tray area 3 adjacent to the idle tray area 3 with multiple seedling trays 2, the worker takes out the first seedling tray 2 near the operation side in the seedling pool 1 below from the tray taking opening 5, and after completing the seedling operations such as sowing, removing dead seedlings, and checking the first seedling tray 2, align the slide grooves 14 on both sides of the first seedling tray 2 with the horizontal movable support plates 13 on both sides of the tray rack 11, and insert the first seedling tray 2 from the opening on the operation side of the tray rack 11 into the tray opening 12. At this time, the first seedling tray 2 is supported on the movable support plates 13 on both sides. Then, the feed drive mechanism 9 drives the feed screws 7 on both sides of the tray area 3 to rotate, so that the feed screws 7 on both sides push the seedling tray 2 to move to the operation side with the help of multiple feed columns 8 on the side of the seedling tray 2, so that the worker can take it. When the second seedling tray 2 completes the seedling operation, the second seedling tray 2 is inserted into the tray opening 12 and supported on the movable support plates 13 on both sides. At this time, the first seedling tray 2 is pushed to the other side. And so on, until all the seedling trays 2 in the second tray area 3 are transferred to the movable support plates 13 on both sides of the tray rack 11, then the slat drive mechanism 15 drives the movable support plates 13 on both sides to rotate, so that the inner sides of the movable support plates 13 on both sides rotate downward, and when the movable support plates 13 are separated from the chute 14, the multiple seedling trays 2 on the movable support plates 13 on both sides fall into the first tray area 3, and when the seedling tray 2 falls, the multiple feed columns 8 on the side of the seedling tray 2 are inserted into the gap of the feed screws 7 on the same side. At this time, the second tray area 3 is in an idle state, and then the above operation is repeated until the seedling raising operation is completed for all the seedling raising trays 2 in the seedling raising pool 1.

[0054] It should be noted that, tray racks 4, tray placing racks 11 and related components can be set at both ends of the seedling pool 1, or the tray placing rack 11 can be set in a way that it can be installed on the other side of the tray rack 4, and the tray rack 4 and the tray placing rack 11 can be reversed, so that the next time the seedling operation is performed, the operation can be performed from the last tray area 3 of the seedling pool 1 to the first tray area 3.

[0055] The present invention divides the seedling pool 1 into N tray areas 3 by a plurality of longitudinal rods 20. The feed screws 7 on both sides of the tray area 3 can, under the drive of the feed drive mechanism 9, push the seedling tray 2 to move toward the worker with the help of a plurality of feed columns 8 on the side of the seedling tray 2. After the seedling tray 2 that has completed the seedling raising operation is taken out, the seedling tray 2 is placed on the movable support plates 13 on both sides of the tray rack 11. When a plurality of seedling trays 2 in a tray area 3 are transferred to two movable support plates 13, the slat drive mechanism 15 drives the movable support plates 13 to release the plurality of seedling trays 2 to the vacant tray area 3, thereby facilitating the taking and re-insertion of the seedling trays 2 in the seedling pool 1, and solving the problem that when the seedling pool 1 is wider, the seedling trays 2 that are far away from the workers are difficult to obtain.

[0056] The feeding drive mechanism 9 includes a lifting frame 901, a bearing plate 902, a driving column gear 903, a lifting assembly 904 and a rotating assembly 905. The bearing plate 902 is fixedly arranged at the end of the feeding frame 4. The lifting frame 901 is connected to the bearing plate 902 through the lifting assembly 904. The driving column gear 903 is rotatably arranged on the lifting frame 901 through the rotating assembly 905, and a pair of driving column gears 903 are arranged.

[0057] The lifting assembly 904 is lifted and lowered by driving the lifting frame 901 so that a pair of active column gears 903 are respectively engaged and separated with the driven column gears 10 on both sides of the plate area 3 , and the rotating assembly 905 drives the driven column gears 10 to rotate with the help of the active column gears 903 .

[0058] Among them, the rotating component 905 includes a longitudinal axis 9051 and a longitudinal servo motor 9052. The longitudinal axis 9051 is rotatably set on the lifting frame 901. The longitudinal servo motor 9052 is set on the lifting frame 901 and connected to the longitudinal axis 9051. The active column gear 903 is set on the longitudinal axis 9051, that is, the longitudinal servo motor 9052 drives the active column gear 903 to rotate through the longitudinal axis 9051, and the active column gear 903 mobilizes the driven column gear 10 to rotate, thereby rotating the feed screw 7 connected to the driven column gear 10, thereby driving the seedling tray 2 connected to the feed screw 7 through the feed column 8 to move along the tray row area 3 in the seedling pool 1.

[0059] Among them, the lifting component 904 includes a screw rod 9041, a driven bevel gear 9042, a driving bevel gear 9043, a transverse shaft 9044 and a transverse servo motor 9045. A threaded hole 16 is provided on the load-bearing plate 902. One end of the screw rod 9041 is rotatably set on the lifting frame 901. The screw rod 9041 is threadedly connected to the upper load-bearing plate 902 through the threaded hole 16. The driven bevel gear 9042 is set on the screw rod 9041. The driving bevel gear 9043 is rotatably set on the lifting frame 901 through the transverse shaft 9044, and the driving bevel gear 9043 is meshed with the driven bevel gear 9042. The transverse servo motor 9045 is set on the lifting frame 901 and connected to the transverse shaft 9044.

[0060] That is, the transverse shaft 9044 is driven to rotate by the transverse servo motor 9045, and the transverse shaft 9044 drives the screw rod 9041 to rotate through the active bevel gear 9043 and the driven bevel gear 9042. The lower end of the screw rod 9041 is axially fixedly connected to the lifting frame 901 through bearings and other components. When the screw rod 9041 rotates back and forth, the screw rod 9041 will be lifted and lowered along the load-bearing plate 902 with the threaded hole 16, and drive the lifting frame 901 to be lifted and lowered.

[0061] Preferably, since the feed screws 7 are provided on both sides of the tray area 3, that is, the feed screws 7 are provided on both sides of the longitudinal rod 20, and the smaller the lateral width of the longitudinal rod 20 is, the smaller the area occupied by the longitudinal rod 20 in the seedling pool 1 is. Therefore, when a pair of active column gears 903 are engaged with the driven column gears 10 on both sides of the tray area 3, the pair of active column gears 903 are located between the driven column gears 10 on both sides, so that the feed screws 7 on both sides of the longitudinal rod 20 can be as close as possible, so as to achieve the purpose of reducing the width of the longitudinal rod 20 and avoiding the longitudinal rod 20 occupying too much area in the seedling pool 1.

[0062] Preferably, guide rails 17 are provided on both sides of the top of the seedling pool 1 along the length direction, and guide grooves 18 are provided on both sides of the bottom of the tray rack 4 and the tray rack 11 to match the guide rails 17. On the one hand, the tray rack 4 and the tray rack 11 are guided by the cooperation of the guide rails 17 and the guide grooves 18 to prevent the tray rack 4 and the guide rack from deflecting, and the tray rack 4 and the tray rack 11 are difficult to stably move along the seedling pool 1. On the other hand, the guide rails 17 assist in supporting the tray rack 4 and the tray rack 11, which is conducive to reducing the load of the traveling mechanism 6. If the tray rack 4 and the tray rack 11 are directly supported on the top of the seedling pool 1, the seedling trays 2 and the longitudinal rods 20 in the seedling pool 1 may collide with the bottom of the tray rack 4 and the tray rack 11, affecting the stable movement of the tray rack 4 and the tray rack 11.

[0063] Among them, the slat driving mechanism 15 includes a rotating shaft 1501, a transmission gear 1502, a transmission rack 1503 and a linkage beam 1504. One side of the movable support plate 13 is rotatably set on the disk rack 11 through the rotating shaft 1501. Transmission gears 1502 are set at both ends of the rotating shaft 1501. The transmission rack 1503 is vertically slidably set on the hole wall of the disk placement port 12 and is meshed and connected with the transmission gear 1502.

[0064] When the two transmission racks 1503 at the same end are moved upward through the linkage beam 1504, the transmission gear 1502 is driven by the outer transmission rack 1503 to rotate, so that the movable support plate 13 inside the transmission gear 1502 rotates downward, and the movable support plate 13 is disengaged from the slide groove 14 on the side of the seedling tray 2, so that the seedling tray 2 falls due to the loss of support from the movable support plates 13 on both sides, and the fallen seedling tray 2 falls into the seedling pool 1 through the tray placing port 12 of the tray placing rack 11.

[0065] On the contrary, when the linkage beam 1504 is pushed downward, the movable support plate 13 rotates upward, so that the inner side of the movable support plate 13 extends into the tray placement opening 12, so that the seedling tray 2 can be supported on the tray placement rack 11 by sliding and plugging the slide grooves 14 on both sides and the movable support plates 13 on both sides, and can move along the width direction of the seedling pool 1, so that multiple seedling trays 2 can be arranged in the tray placement opening 12 above the tray arrangement area 3.

[0066] In addition, groove structures are provided on the hole walls on both sides of the tray placement opening 12, and the movable support plate 13 can be stored in the groove structures when rotating downward to prevent the movable support plate 13 from hindering the seedling tray 2 from falling. Moreover, because the movable support plate 13 can be stored in the groove structures, the width of the tray placement opening 12 and the seedling tray 2 in the lateral direction of the seedling pool 1 is highly matched, thereby helping the seedling tray 2 to accurately fall into the tray arrangement area 3 when falling from the tray placement opening 12.

[0067] In addition, the linkage beam 1504 is connected to the two transmission racks 1503 located at the same end of the movable support plates 13 on both sides, and the screw rod 9041 passes through the top of the threaded hole 16 and is connected to the linkage beam 1504. The screw rod 9041 drives the lifting frame 901 and the linkage beam 1504 to rise, so that the active column gear 903 is disengaged from the driven column gear 10, and the linkage beam 1504 drives the movable support plate 13 to rotate downward with the help of the transmission gear 1502 and the transmission gear 1502.

[0068] Among them, the feed column 8 is a cylinder with one end vertically arranged on the side of the seedling tray 2. The side of the cylindrical feed column 8 is circular. When the feed screw 7 pushes the feed column 8, the shape of the contact point between the feed screw 7 and the feed column 8 is always consistent, which is conducive to the feed screw 7 to stably push the seedling tray 2. The cylindrical feed column 8 has a smooth side, which is conducive to reducing the wear of the feed screw 7.

[0069] Wheel tracks 19 are provided on both sides of the seedling pool 1 in the longitudinal direction. The traveling mechanism 6 includes a wheel frame 601 and a traveling wheel 602. The upper end of the wheel frame 601 is connected to the load-bearing plate 902. The traveling wheel 602 is rotatably arranged on the wheel frame 601 through the wheel axle 603. The traveling wheel 602 is supported on the top of the wheel track 19 and is located between the wheel frame 601 and the seedling pool 1, that is, by pushing the tray rack 4 and the tray rack 11, the tray rack 4 and the tray rack 11 are moved to the top of multiple tray areas 3 in sequence. It should be noted that this technical solution is only one embodiment of the traveling mechanism 6, which helps to understand how the traveling mechanism 6 is connected to the tray rack 4. Further, a wheel drive assembly connected to the traveling wheel 602 can be arranged on the wheel frame 601, thereby realizing automatic movement and positioning of the seedling equipment.

[0070] Working principle:

[0071] When the tray placing opening 12 of the tray placing rack 11 is aligned with the idle tray row area 3, and the tray taking opening 5 of the tray feeding rack 4 is aligned with the second tray row area 3 adjacent to the idle tray row area 3 and equipped with multiple seedling trays 2, the transverse servo motor 9045 drives the transverse shaft 9044 to rotate, so that the transverse shaft 9044 drives the screw rod 9041 to rotate with the aid of the active bevel gear 9043 and the driven bevel gear 9042, so that the self-weight of the screw rod 9041 and the reverse push of the load-bearing plate 902 threadedly connected thereto drive the lifting frame 901 to move downward, so that a pair of active column gears 903 on the lifting frame 901 are meshed and connected with the two driven column gears 10 at one end of the two feed screws 7 on both sides of the second tray row area 3. The screw rod 9041 drives the linkage beam 1504 to move downward, so that the two transmission racks 1503 connected to the linkage beam 1504 move downward and drive the transmission gear 1502 to rotate. The transmission gear 1502 drives the movable support plate 13 to rotate to a horizontal position through the rotating shaft 1501. At this time, the inner side of the movable support plate 13 extends into the tray opening 12 of the tray rack 11. When the worker takes out the first seedling tray 2 near the operating side in the lower seedling pool 1 from the tray opening 5, after completing the seedling operation on the first seedling tray 2, the slide grooves 14 on both sides of the first seedling tray 2 are aligned with the horizontal movable support plates 13 on both sides of the tray rack 11, and the first seedling tray 2 is inserted into the tray opening 12 from the opening on the operating side of the tray rack 11. At this time, the first seedling tray 2 is supported on the movable support plates 13 on both sides. Then, the longitudinal servo motor 9052 drives the feed screws 7 on both sides of the tray area 3 to rotate through the active column gear 903 and the driven column gear 10 in turn, so that the feed screws 7 on both sides push the seedling tray 2 to move toward the operation side with the help of multiple feed columns 8 on the side of the seedling tray 2 for the workers to take. When the second seedling tray 2 completes the seedling operation, the second seedling tray 2 is inserted into the tray opening 12 and supported on the movable support plates 13 on both sides. At this time, the first seedling tray 2 is pushed to the other side. The process is analogous to that above until all the seedling trays 2 in the second tray row area 3 are transferred to the movable support plates 13 on both sides of the tray rack 11. Subsequently, the transverse servo motor 9045 drives the linkage beam 1504 to rise, causing the inner sides of the movable support plates 13 on both sides to rotate downward. When the movable support plates 13 are disengaged from the slide grooves 14, the multiple seedling trays 2 on the movable support plates 13 on both sides fall into the first tray row area 3, and during the falling process of the seedling trays 2, the multiple feed columns 8 on the sides of the seedling trays 2 are inserted into the gaps of the feed screws 7 on the same side.
