Technical Field

[0001] The utility model relates to the technical field of pepper seed germination acceleration, in particular to a pepper seedling germination acceleration device. Background Art

[0002] Peppers are annual or limited perennial herbs or shrubs belonging to the genus Capsicum in the Solanaceae family. They are also known as sweet peppers, large peppers, vegetable peppers, and chili peppers. Peppers are primarily eaten for their fruit, which is rich in vitamin C and commonly used as a condiment. They are one of China's important agricultural exports. Pepper seed oil is also edible. Besides being eaten fresh, peppers can also be pickled or dried to make dried peppers, chili powder, chili oil, and chili sauce. Peppers are thermophilic crops, preferring warm and humid climates. They are intolerant to cold, waterlogging, and drought. They are sensitive to high temperatures and direct sunlight, and strong sunlight is detrimental to their growth. Artificial propagation of peppers primarily involves seeding, with furrows and ridges dug at regular intervals and irrigation to maintain moisture. Peppers are typically germinated before seedlings are grown. The quality of this germination process affects both germination and plant survival rates. Traditionally, germination methods typically involve wrapping soaked seeds in non-woven fabric and maintaining a constant temperature. This method is relatively cumbersome, leading to the development of a range of chili germination equipment. Existing pepper germination equipment usually uses nutrient solution to spray pepper seeds for germination, but the nutrient solution after spraying is not effectively collected and utilized, resulting in waste of nutrient solution. Therefore, it is necessary to develop a pepper seedling germination device that can collect and reuse the nutrient solution. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-4The germination device for pepper seedlings shown in the figure comprises a germination box 1 and a bottom plate 4. The germination box 1 is fixedly connected to the bottom plate 4. A box door 23 is hinged at the front end of the germination box 1. Several germination trays 2 are detachably connected to the germination box 1. A liquid distribution box 3 is fixedly connected to the bottom plate 4. The upper end of the liquid distribution box 3 is fixedly connected to a delivery pump 20. The input end of the delivery pump 20 is connected to a liquid extraction pipe 21 extending to the bottom of the liquid distribution box 3, and the output end is connected to a liquid outlet pipe. The liquid outlet pipe is connected to a nozzle 5 extending into the germination box 1 through a three-way joint. The nozzle 5 is located above the germination tray 2 and its lower end is fixedly connected to several nozzles 6 facing the upper surface of the germination tray 2. The bottom of the germination tray 2 is tilted downward to the rear end, and a collecting hole is provided on the rear wall of the germination box 1 corresponding to the germination tray 2. The water tank 11 and the rear end of the germination tray 2 have no baffle. During the connection process, the rear end of the germination tray 2 is inserted into the water collecting tank 11. The water collecting tank 11 is connected to the downpipe 12 located on the rear wall of the germination box 1. The water collecting tank 11 is tilted downward toward the downpipe 12. The downpipe 12 passes through the germination box 1 and is connected to the circulation pipe 13. The other end of the circulation pipe 13 is connected to the upper part of the liquid distribution box 3. A circulation pump 14 is connected to the circulation pipe 13. A filter plate is provided at the inlet end of the circulation pump 14. Fluorescent lamps 7 are fixedly connected to the germination tray 2 on both sides of the germination box 1. A serpentine slot is provided at the lower end of the germination tray 2. An electric heating tube 22 is connected in the serpentine slot. A controller 24 is fixedly connected to the box door 23. The delivery pump 20, the circulation pump 14 and the fluorescent lamp 7 are controlled by the controller 24.

[0022] It should be noted that, in this embodiment, a waterproof insulation layer is fixedly connected to the outside of the electric heating tube 22 at the bottom of the germination tray 2, and a flexible joint is provided in the germination box 1 at a position corresponding to the germination tray 2, and the electric heating tube 22 is connected through an interface matching the flexible joint.

[0023] In order to monitor the temperature in the germination box 1 in real time and control the germination temperature in the germination box 1 to be relatively stable, a temperature sensor 8 is fixedly connected to the germination box 1. The temperature sensor 8 is in communication with the controller 24, and the electric heating tube 22 is controlled by the controller 24.

[0024] In order to prevent the pepper seeds from being soaked in too much nutrient solution and ensure that the pepper seeds can absorb enough nutrient solution during the germination process, a number of grooves are provided at the bottom of the germination tray 2 and a layer of non-woven fabric is fixedly connected to the bottom of the germination tray 2. The grooves and the non-woven fabric can temporarily store a portion of the nutrient solution for the pepper seeds to absorb.

[0025] In order to disinfect the collected nutrient solution, ensure the cleanliness of the nutrient solution, and reduce the spread of diseases, a water treatment ultraviolet sterilizer 15 is connected to the circulation pipe 13.

[0026] It should be noted that, in this embodiment, the water treatment ultraviolet sterilizer 15 is an existing device, so its specific structure will not be described in detail herein.

[0027] In order to fully stir the nutrient solution during the preparation process and make the nutrient solution uniform, a rotating shaft 17 is rotatably connected to the liquid preparation box 3 through a bearing, and a number of stirring blades 18 are fixedly connected to the rotating shaft 17 at intervals. One end of the rotating shaft 17 passes through the liquid preparation box 3 and is fixedly connected to the output shaft of the stirring motor 19. The stirring motor 19 is fixedly connected to the outside of the liquid preparation box 3 through a connecting frame and bolts.

[0028] In order to detect the concentration of the nutrient solution in the liquid distribution tank 3 in real time during the process of recovering the nutrient solution, and avoid the problem of poor germination effect due to the low concentration of the nutrient solution in the liquid distribution tank 3, a concentration sensor 16 is fixedly connected to the liquid distribution tank 3, and an alarm light is connected to the outside of the liquid distribution tank 3. The concentration sensor 16 is communicated with the controller 24, and the alarm light is controlled by the controller 24.

[0029] In order to facilitate the disassembly and assembly of the germination tray 2, dovetail blocks 9 are fixedly connected on both sides of the germination box 1, and dovetail grooves 10 are opened on both sides of the germination tray 2, and the dovetail grooves 10 are clamped with the dovetail blocks 9.

[0030] In order to facilitate the overall movement of the device, the lower end of the base plate 4 is fixedly connected to a moving wheel 25. It should be noted that in this embodiment, the moving wheel 25 adopts a universal wheel. In order to ensure stability during use, the universal wheel has a brake mechanism.

[0031] In order to facilitate the addition of materials into the liquid distribution box 3 and prevent debris from entering the liquid distribution box 3 during operation, a feeding port is connected to the upper end of the liquid distribution box 3, and a sealing cover is connected to the feeding port. In order to facilitate the observation of the liquid level in the liquid distribution box 3, a liquid level meter 26 is connected to the outside of the liquid distribution box 3.

[0032] It should be noted that, in this embodiment, in order to ventilate the germination box 1, ventilation holes are provided on the box door 23.

[0033] The working process of this embodiment is as follows:

[0034] When accelerating the germination of pepper seeds, first open the sealing cover of the feeding port at the upper end of the liquid distribution box 3, inject clean water into it, and then start the stirring motor 19 to run. The stirring motor 19 drives the rotating shaft 17 and the stirring blade 18 to rotate. At the same time, nutrient raw materials are added to the liquid distribution box 3 and stirred to mix them. At the same time, the concentration sensor 16 monitors the concentration of the nutrient solution in the liquid distribution box 3 in real time, observes the concentration through the controller 24, and stops dispensing when the concentration reaches the set value. Take out the germination tray 2, lay the pepper seeds flat on the germination tray 2, align the dovetail groove 10 with the dovetail block 9 again for clamping, and insert the rear end of the germination tray 2 into the water collection tank 11, and connect the socket of the electric heating tube 22 to the connector in the germination box 1. Set the upper and lower temperature limits and the lower concentration limit on the controller 24, start the electric heating tube 22 to start heating, and control the electric heating tube 22 to be turned off when the temperature reaches the upper and lower temperature limits. When the temperature is lower than the set lower limit, control the electric heating tube 22 to start; start the fluorescent lamp 7 to provide light for the germination of the garbage seeds, and start the delivery pump 20 at the same time. The delivery pump 20 extracts the nutrient solution in the liquid distribution box 3 through the liquid extraction pipe 21, and delivers it to the nozzle 5 to spray from the nozzle 6 onto the germination tray 2, and the nutrient solution is sprayed. Afterwards, part of the nutrient solution is absorbed by the non-woven fabric layer and partially retained in the groove at the bottom of the germination tray 2, and absorbed from the pepper seeds. The remaining nutrient solution flows along the germination tray 2 into the water collection tank 11 and is collected in the lower liquid pipe 12. The circulation pump 14 is started synchronously and runs. The circulation pump 14 transports the nutrient solution from the circulation pipe 13 to the water treatment ultraviolet disinfector 15. The nutrient solution after disinfection re-enters the liquid distribution box 3. When the concentration sensor 16 detects that the nutrient solution concentration in the liquid distribution box 3 is lower than the set value, the alarm light is on and the delivery pump 20 stops running. At this time, it is necessary to manually open the feeding port of the liquid distribution box 3 to continuously add nutrient raw materials thereto, and control the stirring motor 19 to run continuously. The concentration is observed by the controller 24, and the liquid distribution is stopped when the concentration reaches the set value. In this way, the collection and reuse of the nutrient solution can be realized, and the concentration of the sprayed nutrient solution can be guaranteed to meet the standard, thereby avoiding the problem of poor germination effect caused by the nutrient solution ratio problem.
