Description

Technical Field

[0001] The invention belongs to the technical field of forestry seedling cultivation, and in particular relates to an irrigation device for forestry seedling cultivation. Background Art

[0002] Seedling cultivation means cultivating seedlings. It originally meant cultivating seedlings in a nursery, hotbed or greenhouse in preparation for transplanting them into the land for planting. It can also refer to the stage when various organisms are artificially protected when they are small until they can survive independently. During the seedling cultivation period, the seedlings of trees need to be treated in order to increase the survival rate of the trees.

[0003] In the prior art (Announcement No. CN221768871 U, Patent Name: A Patent Application for a Forestry Seedling Raising Device), workers place the seedlings to be raised into the seedling raising grooves on the seedling raising plate. When watering is required, the watering heads on the fixed pipes accurately water each seedling, thereby improving the utilization rate of water resources, ensuring that each seedling receives consistent watering, and increasing the survival rate of the seedlings, facilitating the work of the workers, and reducing their workload. In the process of implementing this technical solution, it was found that the prior art has at least the following problems:

[0004] During the cultivation period of young tree seedlings, the seedlings need to be watered. Although the above-mentioned watering method ensures the consistency of watering, it cannot quantify the amount of watering for each seedling, nor can it water the seedlings close to the ground.

Pesticides can also be added to the water storage pot 5 to spray the seedlings. The auxiliary component includes a liquid supply pipe 111 connected to one side of the liquid storage pot 6 and the fertilizer storage pot 7, which infiltrates a certain amount of nutrient solution and liquid fertilizer into the soil at the root of each seedling so that the seedlings can absorb the nutrient solution and liquid fertilizer, thereby improving the survival rate of the seedlings.

[0048] like Figure 6-Figure 13 The first gear 86 is fixed to the side of the second gear 87 and the second gear 88 is provided with a first gear 89. The first gear 89 is fixed to the side of the second gear 87 and the first gear 88 is provided with a first gear 89. The first gear 89 is fixed to the top of the first gear 87 and the first gear 88 is fixed to the top of the first gear 87.

[0049] An annular groove 13 is provided on one side of the lining plate 4 and the box body 1 close to the cultivation tray 86, and an arc-shaped slider 14 is slidably connected to the four sides of the annular groove 13 and fixedly matched with the cultivation tray 86, which plays a role of rotational support for the cultivation tray 86 when it rotates on the lining plate 4 and the bottom of the box body 1, thereby improving the rotational stability of the cultivation tray 86, and also effectively supports the seedlings on the cultivation tray 86 to avoid skewing and jamming.

[0050] The adjustment assembly also includes a second sub-gear 92 arranged on the outside of the second main gear 91, and the top of the second sub-gear 92 is fixedly connected to a second electric push rod 93 that rotates with the cover 3, and the top of the second electric push rod 93 is fixedly connected to a threaded rod 94 that rotates with the cover 3. After the second electric push rod 93 adjusts the meshing stroke between the second sub-gear 92 and the second main gear 91 to the right position, the double-headed motor 81 drives the threaded rod 94 to rotate linearly through the meshed second main gear 91 and the second sub-gear 92, and the surface of the threaded rod 94 is threadedly connected with a threaded sleeve 95 from top to bottom, the inner side of the threaded sleeve 95 is fixedly connected to a fixing piece 96, and both sides of the threaded sleeve 95 are fixedly connected to fixing ears 97, the threaded rod 94 drives multiple groups of threaded sleeves 95 to perform lifting and lowering adjustments, and the multiple groups of threaded sleeves 95 drive the fixing piece 96 and the fixing ear 97 to move up and down synchronously;

[0051] The irrigation assembly also includes a first electrically controlled valve 102 connected to the outer end of the water supply pipe 101, and a first quantitative sensor 103 is embedded in the outer end of the first electrically controlled valve 102. The bottom end of the first electrically controlled valve 102 is connected to a first telescopic tube 104 that penetrates and cooperates with the cover 3. Under the action of siphon force, the clean water in the water storage pot 5 located at a high position is supplied into the first telescopic tube 104 through the first electrically controlled valve 102 opened on the water supply pipe 101, and the first quantitative sensor 103 quantitatively processes the amount of water flowing through. The bottom end of the first telescopic tube 104 is connected to a water supply pipe rack 10 fixedly matched with the fixing member 96. 5. The inner end of the water supply pipe rack 105 is connected with a pressure pipe 106 that slides through the box 1, and the inner end of the pressure pipe 106 is connected with a sprinkler head 107 used in conjunction with the cultivation grid 87. After the clean water in the first telescopic tube 104 is pressurized by the pressure pipe 106 on the water supply pipe rack 105, multiple groups of sprinkler heads 107 are used to carry out close quantitative irrigation on each seedling on the cultivation grid 87 after it is rotated into place, saving water while preventing the branches and leaves of the seedlings from blocking the irrigation water and spilling it to the outside, thereby achieving a full irrigation effect for the seedlings. Medicaments can also be added to the water storage pot 5 to spray the seedlings.

[0052] Both the water supply pipe rack 105 and the supply pipe rack 115 adopt a Y-shaped interface design, which is conducive to the smooth flow of purified water, medicine, nutrient solution and liquid fertilizer, and the insertion tube 116 is provided with injection holes 15 around the injection port 117, which assists the insertion tube 116 inserted into the soil at the root of the seedling to overflow the nutrient solution and liquid fertilizer, thereby accelerating the infiltration speed of the nutrient solution and liquid fertilizer.

[0053] The auxiliary component also includes a second electrically controlled valve 112 connected to the outer end of the liquid feeding pipe 111, and a second quantitative sensor 113 is embedded in the outer end of the second electrically controlled valve 112. The bottom end of the second electrically controlled valve 112 is connected to a second telescopic tube 114 that penetrates and cooperates with the cover 3. Under the action of the siphon force, the nutrient solution and liquid fertilizer in the liquid storage pot 6 and the fertilizer storage pot 7 located at a high position are supplied into the second telescopic tube 114 through the second electrically controlled valve 112 opened on the two liquid feeding pipes 111, and the two sets of second quantitative sensors 113 perform quantitative processing on the amount of nutrient solution and liquid fertilizer flowing through. The bottom end of the second telescopic tube 114 is connected to a fixed The ear 97 is embedded with a matching supply pipe rack 115. The inner end of the supply pipe rack 115 is connected to a through-tube 116 that slides through the box 1 and is located above the cultivation tray 86. The bottom end of the through-tube 116 is connected to a liquid injection port 117 used in conjunction with the cultivation grid 87. The nutrient solution and liquid fertilizer in the second telescopic tube 114 flow through the supply pipe rack 115 into the through-tube 116 inserted into the soil at the roots of the seedlings in the cultivation grid 87. The liquid injection port 117 and the liquid injection hole 15 then infiltrate a certain amount of nutrient solution and liquid fertilizer into the soil at the roots of each seedling, so that the seedlings can absorb the nutrient solution and liquid fertilizer, thereby improving the survival rate of the seedlings.

[0054] The box body 1 and the lining plate 4 are fixed with a lighting lamp 16 for use with the cultivation grid 87 on the circumference of the other side near the cultivation tray 86, and the box body 1 is provided with an array of glass lighting areas 17 on both sides to provide sufficient light for the seedlings in the cultivation grid 87, which is beneficial to the photosynthesis of the seedlings. The box body 1 is provided with an array of ventilation fans 18 staggered with the lining plate 4 on both sides near the lighting area 17, and the ventilation fans 18 are located on the outside of the cultivation tray 86, which has a ventilation effect on the seedlings, which is beneficial to maintain air fluidity in the box body 1, allowing oxygen to enter, and avoiding excessive carbon dioxide that affects the growth of the seedlings.

[0055] like Figure 14-16As shown, during the watering, spraying and fertilizing of each seedling, the medicine, nutrient solution and liquid fertilizer cannot be mixed on site, and need to be prepared from elsewhere and transported to the site, which is more troublesome. The water storage pot 5, the liquid storage pot 6 and the fertilizer storage pot 7 are all provided with a spoiler component used in conjunction with the transposition component, and the spoiler component includes a spoiler 121 fixed in an array on the rotating shaft 85 and staggered with the cultivation tray 86. The rotating shaft 85 drives the spoiler 121 distributed in the array to rotate, and performs a spoiler blowing treatment on the seedlings planted between the cultivation trays 86, thereby improving the fluidity of the air in the box 1, so that the seedlings are protected by natural wind, which is beneficial to the normal growth of the seedlings. The top of the rotating shaft 85 is fixedly connected to a driving gear 122 that rotates with the bottom of the water storage pot 5, and the driving gear 122 is fixedly connected to the top of the rotating shaft 85. Both sides of 22 are engaged with driven gears 123 that rotate with the liquid storage pot 6 and the fertilizer storage pot 7. The driving gear 122 is fixedly connected with a first stirring rack 124 for stirring the medicine and purified water in the water storage pot 5, and the driven gear 123 is fixedly connected with a second stirring rack 125 for stirring the nutrient solution in the liquid storage pot 6 and the liquid fertilizer in the fertilizer storage pot 7. The rotating shaft 85 drives the first stirring rack 124 on the driving gear 122 to rotate, and the driving gear 122 drives the second stirring racks 125 on the two groups of driven gears 123 to rotate accordingly, respectively stirring and preparing the medicine and purified water in the water storage pot 5, the nutrient solution in the liquid storage pot 6, and the liquid fertilizer in the fertilizer storage pot 7, thereby achieving the quick effect of on-site preparation and on-site use, without the need for transportation from elsewhere, and high efficiency and labor saving.

[0056] The working principle of a watering device for forestry seedling cultivation is as follows: first, the first electric push rod 84 is controlled to start and drive the first sub-gear 83 to move down and engage with the first main gear 82, then the double-headed motor 81 is controlled to start and drive the rotating shaft 85 to rotate linearly through the first main gear 82 and the first sub-gear 83 engaged in place. The rotating shaft 85 drives the arrayed multiple groups of cultivation trays 86 and the cultivation grids 87 to rotate at a uniform speed, and the seedlings are placed in the cultivation grids 87 on the multiple groups of cultivation trays 86 in turn. After all the seedlings are placed in the cultivation grids 87 on the multiple groups of cultivation trays 86, the seedlings in the first group of cultivation grids 87 are rotated and repositioned to be directly below the sprinkler head 107 and the liquid injection port 117 to wait;

[0057] Before placing the seedlings into the cultivation grid 87, it is necessary to prepare the medicine and purified water in the water storage pot 5, the nutrient solution in the liquid storage pot 6, and the liquid fertilizer in the fertilizer storage pot 7. The rotating shaft 85 drives the array of distributed spoilers 121 to rotate, thereby improving the fluidity of the air in the box 1. While simulating natural wind for the seedlings, the rotating shaft 85 also drives the first stirring rack 124 on the driving gear 122 to rotate synchronously. The driving gear 122 drives the second stirring rack 125 on the two sets of driven gears 123 to rotate accordingly. The first stirring rack 124 in the rotating state is rotated. The rack 124 mixes the medicine and clean water added to the water storage pot 5 to prepare the medicine. The medicine is added only when the seedlings are infected with diseases and insect pests. Clean water is usually added for irrigation. The two rotating second mixing racks 125 mix the nutrient solution raw materials added to the liquid storage pot 6 and the liquid fertilizer raw materials added to the fertilizer storage pot 7 to prepare nutrient solution and liquid fertilizer for use respectively. Then the double-headed motor 81 is controlled to pause, and the first electric push rod 84 is controlled to close and drive the first sub-gear 83 to move up and disengage from the meshing portion of the first main gear 82 to the initial position;

[0058] Next, the second electric push rod 93 is controlled to open and drive the second sub-gear 92 to move down to the meshing portion of the second main gear 91, and then the double-headed motor 81 is controlled to open again and drive the threaded rod 94 to rotate forward through the second main gear 91 and the second sub-gear 92 that are meshed in place. The threaded rod 94 drives the multiple groups of threaded sleeves 95 distributed in the array to move downward synchronously. The multiple groups of threaded sleeves 95 drive the water supply pipe rack 105 to move downward through the fixing member 96, and stretch the first telescopic pipe 104 on it downward until the water supply is The pipe rack 105 drives the sprinkler head 107 downward to the watering position of the first group of seedlings. At the same time, the multiple sets of threaded sleeves 95 drive the supply pipe rack 115 downward through the fixing ears 97 and stretch the second telescopic tube 114 thereon downward until the supply pipe rack 115 drives the insertion tube 116 to be inserted into the soil at the roots of the first group of seedlings. The double-headed motor 81 is first controlled to pause, and then the second electric push rod 93 is controlled to close and drive the second sub-gear 92 to move upward to disengage the meshing portion of the second main gear 91 to the initial position.

[0059] Then, the purified water in the water storage pot 5 located at the upper position is supplied to the first telescopic tube 104 through the first electrically controlled valve 102 opened on the water supply pipe 101. The first quantitative sensor 103 quantitatively controls the amount of purified water flowing through the first electrically controlled valve 102. The purified water in the first telescopic tube 104 then passes through the lowered water supply pipe rack 105 to the pressurized pipe 106 for pressurization. The pressurized purified water is then quantitatively irrigated to the first group of seedlings through the closely positioned sprinkler head 107.

[0060] At the same time, the nutrient solution and liquid fertilizer in the liquid storage pot 6 and the fertilizer storage pot 7 located at the top are supplied into the two second telescopic tubes 114 through the second electrically-controlled valves 112 opened on the two liquid supply pipes 111, and the two groups of second quantitative sensors 113 quantitatively control the amount of nutrient solution and liquid fertilizer flowing through the two groups of second electrically-controlled valves 112. Then, the nutrient solution and liquid fertilizer in the second telescopic tubes 114 reach the interpenetrating tube 116 inserted into the soil at the roots of the first group of seedlings through the supply pipe rack 115 that has moved down to its place, and then the nutrient solution and liquid fertilizer are quantitatively infiltrated into the soil at the roots of the first group of seedlings through the liquid injection port 117 and the liquid injection hole 15. After the first group of seedlings completes the watering and fertilizing operations, the first control After the threaded rod 94 is reversed and drives the spray head 107 and the liquid injection port 117 to move up and reset, similarly, the multiple groups of cultivation trays 86 are controlled to rotate linearly until the second group of seedlings in the cultivation grid 87 are rotated and replaced to just below the reset state of the spray head 107 and the liquid injection port 117. Similarly, each seedling in the cultivation grid 87 on the multiple groups of cultivation trays 86 is quantitatively watered and fertilized. If it is necessary to spray the seedlings regularly, the added medicine and clean water in the water storage pot 5 are first stirred into the medicine through the first stirring rack 124. Similarly, the original route is used to evenly spray the medicine to the multiple groups of seedlings through the spray head 107 that is close to the position, thereby completing the regular spraying operation for each seedling.

[0061] It should be noted that the specific models and specifications of the double-headed motor 81, electric push rod and lighting lamp 16 as well as various sensors and valves need to be selected and determined according to the actual specifications of the device.
