Technical Field
[0001] This utility model relates to the field of rice seedling tray technology, and in particular to a bottomless soil-free rice seedling tray. Background Technology
[0002] Bottomless rice seedling trays are agricultural tools used for rice seedling raising. They make it easier to remove rice seedlings, reduce soil erosion, improve field utilization, effectively reduce seedbed diseases, provide a good growth environment for seedlings, and promote increased yield.
[0003] Bottomless rice seedling trays contain sponge blocks with seedling troughs for seedlings. As the rice seedlings grow, the nutrients in the trays are gradually consumed, so nutrient solution needs to be added regularly. However, the presence of the sponge blocks makes it difficult to distribute the nutrient solution evenly inside the trays, which may lead to malnutrition in some seedlings and slow growth. Utility Model Content
[0004] This invention provides a bottomless rice seedling tray to address the problem that when nutrient solution is poured into a seedling tray, the presence of a sponge block makes it difficult to distribute the nutrient solution evenly inside the tray, which may lead to malnutrition and slow growth in some seedlings.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bottomless rice seedling tray, comprising a seedling tray body, wherein a sponge block is provided inside the seedling tray body, and a plurality of seedling holes are evenly opened on the top of the sponge block, and an auxiliary device is provided at the bottom of the seedling tray body, wherein the auxiliary device holds a nutrient solution by setting an auxiliary box at the bottom of the seedling tray body, so as to assist the nutrient solution in being evenly distributed inside the seedling tray body and the sponge block.
[0006] The effect achieved by the above components is as follows: by setting up an auxiliary box, the nutrient solution is poured into the auxiliary box and the nutrient solution is fully mixed with the solution in the auxiliary box. Then, the seedling pot body and the sponge block are immersed in the newly added nutrient solution. The sponge block will absorb the nutrient solution, which can ensure that the nutrient solution in the sponge block is evenly distributed, thereby helping the rice seedlings to absorb sufficient nutrients and grow rapidly.
[0007] Preferably, the auxiliary device includes an auxiliary box, the seedling tray body is disposed inside the auxiliary box, the bottom of each of the four sides of the seedling tray body is provided with a connecting hole, a rectangular tube is fixedly installed on both sides of the auxiliary box, a rectangular plate is slidably installed on the inner wall of the rectangular tube, and one end of the two rectangular plates is symmetrically fixedly installed on both sides of the bottom of the seedling tray body.
[0008] The effect achieved by the above components is as follows: push the seedling tray body upward so that the seedling tray body is away from the auxiliary box, then pour nutrient solution into the auxiliary box and mix it fully with the original nutrient solution in the auxiliary box, and finally push the seedling tray body so that the nutrient solution fully wets the sponge block through the connecting hole, thereby ensuring that the nutrient solution is fully distributed inside the sponge block.
[0009] Preferably, a bolt is threaded into the top of one side of the rectangular tube.
[0010] The effect achieved by the above components is as follows: when nutrient solution needs to be added, the bolt is rotated so that one end of the bolt abuts against one side of the rectangular plate, thereby fixing the seedling tray body, which is convenient for adding and stirring nutrient solution, and also convenient for fixing the seedling tray body inside the auxiliary box during the subsequent seedling process.
[0011] Preferably, a rubber strip is adhered to the inner wall of one side of the rectangular plate, and the bolt is located on one side of the rubber strip.
[0012] The effect achieved by the above components is that by setting the rubber strip, one side of the rectangular plate can be replaced to abut against one end of the bolt, and the friction between the bolt and the rectangular plate can be increased, making the bolt more secure in fixing the seedling pot body and the auxiliary box.
[0013] Preferably, springs are fixedly installed on both sides of the bottom of the seedling tray body, and one end of the spring is fixedly installed on the bottom of both sides of the auxiliary box.
[0014] The effect achieved by the above components is as follows: by setting a spring, when the seedling tray body is pushed downward, the seedling tray body will squeeze the spring when the sponge block is soaked in the nutrient solution, causing the spring to deform. When the force applied to the seedling tray body is removed, the spring will reset and drive the seedling tray body to automatically move away from the auxiliary box, which facilitates quick addition of nutrient solution and other operations.
[0015] Preferably, the spring has a round rod inside, one end of which is fixedly installed on one side of the bottom of the auxiliary box, and the seedling tray body is slidably installed on the outer surface of the two round rods.
[0016] The effect achieved by the above components is that by setting the round rod, the round rod can limit and guide the spring, which helps to prevent the spring from easily bending during deformation.
[0017] Preferably, a circular block is fixedly installed at one end of the circular rod, and the outer diameter of the circular block is larger than the outer diameter of the circular rod.
[0018] The effect achieved by the above components is that by setting up a round block, the round block can block one end of the round rod, which helps to prevent the seedling tray from falling off the limit of the two round rods due to misoperation.
[0019] Preferably, the bottom of the connecting hole is an outwardly sloping surface.
[0020] The effect achieved by the above components is as follows: when the seedling tray moves rapidly upward under the action of the spring, the connecting groove will carry some of the nutrient solution upward, and the inclined connecting groove can play a guiding role, so that more of the carried-out nutrient solution can quickly flow back into the auxiliary box, making it easier to adjust the solution.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up an auxiliary box, the nutrient solution is poured into the auxiliary box and thoroughly mixed with the solution in the auxiliary box. Then, the seedling pot body and the sponge block are immersed in the newly added nutrient solution. The sponge block will absorb the nutrient solution, which can ensure that the nutrient solution in the sponge block is evenly distributed, thereby helping the rice seedlings to absorb sufficient nutrients and grow rapidly.

[0028] Example 1, referring to Figures 1-3As shown, this embodiment discloses a bottomless rice seedling tray, including a seedling tray body 1. A sponge block 2 is arranged inside the seedling tray body 1. Several seedling holes 3 are evenly opened on the top of the sponge block 2. An auxiliary device 4 is arranged at the bottom of the seedling tray body 1. The auxiliary device 4 holds a nutrient solution by setting an auxiliary box 41 at the bottom of the seedling tray body 1, so as to help the nutrient solution be evenly distributed inside the seedling tray body and the sponge block 2. By setting the auxiliary box 41, the nutrient solution is poured into the auxiliary box 41 and the nutrient solution is fully mixed with the solution in the auxiliary box 41. Then, the seedling tray body and the sponge block 2 are immersed in the newly added nutrient solution, which can ensure that the nutrient solution in the sponge block 2 is evenly distributed, thereby helping the rice seedlings to absorb sufficient nutrients and grow rapidly.
[0029] Reference Figure 2 and Figure 3 As shown, the auxiliary device 4 includes an auxiliary box 41, with the seedling tray body 1 disposed inside the auxiliary box 41. Each of the four sides of the seedling tray body 1 has a connecting hole 42 at its bottom. Rectangular cylinders 44 are fixedly installed on both sides of the auxiliary box 41. Rectangular plates 43 are slidably installed on the inner wall of the rectangular cylinders 44. One end of each of the two rectangular plates 43 is symmetrically fixed on both sides of the bottom of the seedling tray body 1. The seedling tray body 1 is pushed upwards, moving it away from the auxiliary box 41. Nutrient solution is then poured into the auxiliary box 41, mixing with the existing nutrients in the auxiliary box 41. The nutrient solution is thoroughly mixed, and then the seedling tray body 1 is pushed so that the nutrient solution fully soaks the sponge block 2 through the connecting hole 42, thereby ensuring that the nutrient solution is fully distributed inside the sponge block 2; a bolt 45 is threaded into the top of one side of the rectangular tube 44. When nutrient solution needs to be added, the bolt 45 is rotated so that one end of the bolt 45 abuts against one side of the rectangular plate 43, thereby fixing the seedling tray body 1, which is convenient for adding and stirring the nutrient solution, and also convenient for fixing the seedling tray body 1 inside the auxiliary box 41 during the subsequent seedling raising process.
[0030] Reference Figure 2 and Figure 3 As shown, a rubber strip 46 is bonded to the inner wall of one side of the rectangular plate 43, and a bolt 45 is set on one side of the rubber strip 46. By setting the rubber strip 46, one side of the rectangular plate 43 can be replaced to abut against one end of the bolt 45, and the friction between the bolt 45 and the rectangular plate 43 can be increased, making the bolt 45 more secure in fixing the seedling pot body and the auxiliary box 41.
[0031] Reference Figure 4As shown, springs 47 are fixedly installed on both sides of the bottom of the seedling tray body 1. One end of the spring 47 is fixedly installed on the bottom of both sides of the auxiliary box 41. By setting the spring 47, the seedling tray body 1 is pushed downward, so that when the sponge block 2 is soaked in the nutrient solution, the seedling tray body 1 will squeeze the spring 47, causing the spring 47 to deform. When the force applied to the seedling tray body 1 is removed, the spring 47 will return to its original position and drive the seedling tray body 1 to automatically move away from the auxiliary box 41, which facilitates the quick addition of nutrient solution and other operations. A round rod 48 is set inside the spring 47. One end of the round rod 48 is fixedly installed on one side of the bottom of the auxiliary box 41. The seedling tray body 1 is slidably installed on the outer surface of the two round rods 48. By setting the round rods 48, the round rods 48 can limit and guide the spring 47, which helps to prevent the spring 47 from easily bending during the deformation process.
[0032] Reference Figure 2 and Figure 4 As shown, a circular block 49 is fixedly installed at one end of the circular rod 48. The outer diameter of the circular block 49 is larger than the outer diameter of the circular rod 48. By setting the circular block 49, the circular block 49 can block one end of the circular rod 48, which helps to prevent the seedling tray body 1 from being separated from the limit of the two circular rods 48 due to misoperation. The bottom of the connecting hole 42 is an outward inclined slope. When the seedling tray body 1 moves upward rapidly under the action of the spring 47, the connecting groove will carry some nutrient solution upward. The inclined connecting groove can play a guiding role, so that more of the carried-out nutrient solution can quickly flow back into the auxiliary box 41, which makes it easier to adjust the solution.
[0033] Working principle: When nutrient solution needs to be added, rotate the two bolts 45 to move them away from one side of the rectangular plate 43, thereby releasing the restriction between the rectangular plate 43 and the rectangular cylinder 44. The spring 47 will reset and drive the seedling tray body 1 to move automatically upward, moving the seedling tray body 1 away from the auxiliary box 41. Then, nutrient solution is added to the auxiliary box 41 and fully mixed with the original nutrient solution in the auxiliary box 41. Finally, the seedling tray body 1 is pushed downward, which will compress the spring 47, causing the spring 47 to deform until the seedling tray body 1... The bottom of the container abuts against the top of the inner wall of the auxiliary box 41. By rotating the bolt 45, one end of the bolt 45 abuts against the rubber strip 46 on one side of the rectangular plate 43, thereby fixing the seedling tray body 1. The nutrient solution can then fully soak the sponge block 2 through the connecting hole 42, thus ensuring that the nutrient solution is fully and evenly distributed inside the sponge block 2. (It should be noted that the auxiliary box 41, rectangular plate 43, rectangular tube 44, bolt 45, round rod 48 and round block 49 are all made of plastic, and the spring 47 is made of stainless steel, which saves costs and prevents oxidation and corrosion due to humid environments.)
