Abstract
Description
Technical Field
[0001] This utility model belongs to the field of crop planting technology, and in particular relates to a constant temperature germination and seedling raising device for crops. Background Technology
[0002] The constant temperature germination and seedling raising device for crops is a device specifically designed for germinating crop seeds before sowing. It aims to accelerate seed germination, shorten germination time, and improve the uniformity and survival rate of seedlings.
[0003] Existing seedling germination and cultivation devices typically hold multiple seedling boxes. Due to the sterilization and nutrient solution spraying inside the device, the shelves remain damp. When workers are handling seedling boxes, they may accidentally touch other boxes, causing them to slip and fall to the ground. This severely impacts seed germination and results in economic losses. Therefore, we propose a constant-temperature seedling germination and cultivation device for crops. Utility Model Content
[0004] The purpose of this invention is to provide a constant-temperature germination and seedling raising device for crops. Specifically, a positioning component is used to place the seedling box between a movable positioning frame and a fixed positioning frame. The movable positioning frame, in conjunction with the fixed positioning frame, clamps and positions the seedling box. Then, a screw-on knob is turned clockwise to fix the movable positioning frame. At this point, the seedling box is positioned and easily secured, preventing it from falling when touched. This effectively protects the seeds inside the seedling box from damage. Furthermore, the movable positioning frame can accommodate seedling boxes of different sizes. This solves the problem in existing germination and seedling raising devices where the internal sterilization and nutrient solution spraying keeps the placement rack moist, causing other seedling boxes to slip and fall due to the dampness when workers are handling them.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a constant-temperature germination and seedling raising device for crops, comprising a seedling box with a transparent glass door on the front. A control panel is fixedly connected to the center of the front of the seedling box. The inside of the seedling box is divided into two constant-temperature chambers. Two fans are fixedly connected to the top of the seedling box, with each fan corresponding to one of the two constant-temperature chambers. Several placement racks are fixedly connected to the inner wall of each constant-temperature chamber. The top of each placement rack contacts two seedling boxes. A positioning component is provided on the outside of each seedling box. The positioning component includes a movable positioning frame and a fixed positioning frame, which are respectively located on the left and right sides of the seedling box. The bottom of the fixed positioning frame is fixedly connected to the top of the placement rack. A limiting groove is formed on the top of the placement rack. A limiting rod is fixedly connected to the left side of the movable positioning frame. A fixing plate is fixedly connected to the front of the movable positioning frame. A threaded knob is threadedly connected inside the fixing plate, with the back of the threaded knob contacting the front of the placement rack. The limiting rod is slidably connected to the placement rack through the limiting groove. The movable positioning frame, in cooperation with the fixed positioning frame, clamps and positions the seedling boxes, preventing them from falling when touched.
[0007] Furthermore, the corresponding sides of the movable positioning frame and the fixed positioning frame are in contact with the outer surface of the seedling box, and the bottom of the movable positioning frame is in contact with the top of the placement frame; when ventilation is performed, air will flow downward through the trough to improve the ventilation effect, and at the same time, it can blow the residual liquid on the placement frame downward and discharge it, greatly reducing the residual liquid on the placement frame.
[0008] Furthermore, the placement rack has several slots inside, and a heater is fixedly connected to the bottom of each slot. Two lights are fixedly connected to the bottom of each heater, and a temperature sensor is fixedly connected to the inner wall of the constant temperature chamber. The heater heats the inside of the seedling box to maintain the temperature inside the seedling box, and the temperature sensor senses the temperature inside the seedling box and sends the temperature signal to the control panel. The control panel controls the heater, thereby achieving a constant temperature inside the seedling box.
[0009] Furthermore, a groove is provided at the center of the back of the seedling box. A sterilization liquid tank and a nutrient solution tank are fixedly connected to the bottom of the inner wall of the groove. A booster pump is fixedly connected to the top of the sterilization liquid tank. A diversion pipe is fixedly connected to the top outlet of the booster pump. Several spray pipes are fixedly connected to the outer surface of the diversion pipe. A booster pump is fixedly connected to the top of the nutrient solution tank. A diversion pipe is fixedly connected to the top outlet of the booster pump. A spray pipe is fixedly connected to the outer surface of the diversion pipe. When the booster pump is started, it draws the sterilization liquid in the sterilization liquid tank into the diversion pipe and distributes it to several spray pipes. Then, it is sprayed out through atomizing nozzles, thereby sterilizing the inside of the seedling box. When the booster pump is started, it delivers the nutrient solution in the nutrient solution tank to the diversion pipe and then distributes it to several spray pipes. Finally, it is sprayed out through atomizing nozzles to provide nutrition to the seeds.
[0010] Furthermore, both the back of the sterilization solution tank and the back of the nutrient solution tank are fixedly connected to inlet pipes. Both spray pipe one and spray pipe two penetrate the seedling box and extend into the constant temperature room. Both spray pipe one and spray pipe two are fixedly connected to several atomizing nozzles at their bottoms. Both spray pipe one and spray pipe two are positioned above the seedling box. The inlet pipe on the sterilization solution tank is used to add sterilization solution, and the inlet pipe on the nutrient solution tank is used to add nutrient solution.
[0011] Furthermore, two collection boxes are inserted into the bottom back of the seedling box. The collection boxes are located at the bottom of the constant temperature chamber. Two guide plates are fixedly connected to the bottom of the placement rack at the bottom. The two guide plates are symmetrically arranged. Excess disinfectant and nutrient solution sprayed out will flow down and be collected in the collection boxes by the guide plates, which is convenient for staff to handle later.
[0012] This utility model has the following beneficial effects:
[0013] 1. This utility model, by setting a positioning component, specifically places the seedling box between a movable positioning frame and a fixed positioning frame, so that the movable positioning frame, in cooperation with the fixed positioning frame, clamps and positions the seedling box. Then, the movable positioning frame is fixed by rotating the threaded knob clockwise. At this time, the seedling box is positioned and easily fixed, which can prevent the seedling box from falling when touched, effectively protecting the seeds inside the seedling box from damage. Furthermore, the movable positioning frame can accommodate seedling boxes of different sizes.
[0014] 2. This utility model incorporates a trough, where excess nutrient solution and sterilizing solution sprayed out are discharged through the trough on the placement rack and guided into the collection box by a guide plate, thereby reducing residue. Furthermore, during ventilation, air flows downward through the trough, improving ventilation and blowing away any residual liquid on the placement rack, significantly reducing residual liquid on the rack and further preventing the seedling box from slipping.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0026] Please see Figure 1-6As shown, this utility model is a constant temperature germination and seedling raising device for crops, including a seedling box 1. A transparent glass door 11 is provided on the front of the seedling box 1. A control panel 111 is fixedly connected to the center of the front of the seedling box 1.

The limiting rod 133 is slidably connected to the placement frame 12 through the limiting groove 123. By setting the positioning component 13, specifically placing the seedling tray 122 between the movable positioning frame 131 and the fixed positioning frame 132, the movable positioning frame 131... The seedling box 122 is clamped and positioned by cooperating with the fixed positioning frame 132. Then, the movable positioning frame 131 is fixed by rotating the threaded knob 135 clockwise. At this time, the seedling box 122 is positioned and simply fixed, which can prevent the seedling box 122 from falling when touched, effectively protecting the seeds inside the seedling box 122 from damage. The movable positioning frame 131 can accommodate seedling boxes 122 of different sizes. The corresponding sides of the movable positioning frame 131 and the fixed positioning frame 132 are in contact with the outer surface of the seedling box 122, and the bottom of the movable positioning frame 131 is in contact with the top of the placement frame 12.

Several atomizing nozzles are fixedly connected to the bottom of spray pipe 1 23 and spray pipe 2 33. Spray pipe 1 23 and spray pipe 2 33 are both located above the seedling box 122. Two collection boxes 4 are inserted into the bottom of the back of the seedling box 1. The collection boxes 4 are located at the bottom of the constant temperature chamber. Two guide plates 41 are fixedly connected to the bottom of the placement rack 12 at the bottom. The two guide plates 41 are symmetrically arranged.
[0027] One specific application of this embodiment is:
[0028] In use, open the transparent glass door 11, then place the seedling box 122 on the placement rack 12, positioning it between the movable positioning rack 131 and the fixed positioning rack 132. Next, turn the threaded knob 135 counterclockwise to release the movable positioning rack 131. Then, push the movable positioning rack 131 forward, causing the limiting rod 133 to slide within the limiting groove 123, thus limiting the movement. This allows the movable positioning rack 131 to clamp and position the seedling box 122 in cooperation with the fixed positioning rack 132. Finally, turn the threaded knob 135 clockwise to bring it into contact with the front of the placement rack 12, thereby fixing the movable positioning rack 131 in place. At this point, the seedling box 122... 2. The seedling box 122 is positioned and easily fixed, which can prevent it from falling when touched, effectively protecting the seeds inside the seedling box 122 from damage. After multiple seedling boxes 122 are placed, the transparent glass door 11 is closed, the light 125 serves as illumination, the heater 124 heats the inside of the seedling box 1 to maintain the temperature inside the seedling box 1, the temperature sensor 113 senses the temperature inside the seedling box 1 and sends the temperature signal to the control panel 111, and the control panel 111 controls the heater 124 to achieve a constant temperature inside the seedling box 1, thereby improving the seedling effect.
[0029] When it is necessary to sterilize the inside of the seedling box 1 or add nutrient solution to the seeds, the booster pump 1 21 or booster pump 2 31 is started via the control panel 111. When booster pump 1 21 is started, the sterilizing solution in the sterilizing solution tank 2 is drawn into the diversion pipe 1 22 and then distributed to several spray pipes 1 23. It is then sprayed out through the atomizing nozzle, thereby sterilizing the inside of the seedling box 1. When booster pump 2 31 is started, the nutrient solution in the nutrient solution tank 3 is transported to the diversion pipe 2 32 and then distributed to several spray pipes 2 33. It is then sprayed out through the atomizing nozzle to apply nutrients to the seeds, effectively promoting seed germination. Since several troughs 121 are provided on the placement rack 12, the sprayed sterilizing solution and nutrient solution will flow down and finally enter the collection box 4 for collection by the guide plate 41, which is convenient for subsequent processing by the staff.
[0030] When ventilation is required inside the seedling box 1, the fan 112 is started via the control panel 111 to blow air into the seedling box 1. The air will then flow downward through the trough 121, improving the ventilation effect. During ventilation, residual liquid on the rack 12 is blown downward and discharged, greatly reducing the amount of liquid remaining on the rack 12, thus preventing the seedling box 122 from slipping off. The ventilation function further promotes seed germination.
