[0029] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figure 1 As shown, this embodiment provides an automatic seedling containerization device, comprising a substrate lifting mechanism 1, a substrate filling mechanism 2 located below the discharge end of the substrate lifting mechanism 1, a conveying mechanism 3 located below the substrate filling mechanism 2, and a planting mechanism 4 and a spraying mechanism 5, which are sequentially arranged on the conveying mechanism 3 along the conveying direction of the conveying mechanism. The substrate lifting mechanism 1 can generally be an inclined belt conveyor, which is used to transport the substrate from a lower location to a higher location, so that the substrate, under its own gravity, passes downward through the substrate filling mechanism 2 and is filled. The substrate filling mechanism 2 is primarily used to control the amount of substrate discharged and accurately guide the substrate into the seedling bags or seedling cups. The conveying mechanism 3 can generally be a horizontal belt conveyor, which is used to sequentially transport the filled seedling bags or seedling cups to the planting mechanism 4 and the spraying mechanism 5. The planting mechanism 4 is primarily used to drill holes in the substrate within the seedling bags or seedling cups to facilitate the insertion of the seedlings. The spraying mechanism 5 is used to spray an appropriate amount of water into the substrate. The substrate lifting mechanism 1, conveying mechanism 3, implanting mechanism 4 and spraying mechanism 5 described above can all adopt existing conventional structures, and will not be described in detail here.

[0031] like Figure 2 and 3As shown, the matrix filling mechanism 2 includes a filling frame 21, a receiving hopper 22, a first material baffle plate 23, a quantitative material barrel 24, a pushing cylinder 25, a second material baffle plate 26, and a discharge barrel 27. The first material baffle plate 23 is slidably connected to the lower end of the receiving hopper 22, and the output end of the pushing cylinder 25 is connected to the first material baffle plate 23. The first material baffle plate 23 is provided with a first discharge hole 231, and the quantitative material barrel 24 is connected to the first discharge hole 231 on the lower side of the first material baffle plate 23. The second material baffle plate 26 is slidably connected to the lower end of the quantitative material barrel 24, and the second material baffle plate 26 is provided with a second discharge hole 261. The discharge barrel 27 is connected to the second discharge hole 261 on the lower side of the second material baffle plate 26; the upper and lower ends of the quantitative material barrel 24 are both open, and the positions of the lower end of the receiving hopper 22 and the second discharge hole 261 are staggered. In this way, since the positions of the lower end of the receiving hopper 22 and the second discharge hole 261 are staggered with each other, when the upper end of the metering barrel 24, that is, the first discharge hole 231, is aligned with the lower end of the receiving hopper 22, the lower end of the metering barrel 24 abuts against the second material stop plate 26. When the metering barrel 24 is full of the matrix, it moves toward the second discharge hole 261 under the drive of the pushing cylinder 25. During this process, the upper end of the metering barrel 24 and the lower end of the receiving hopper 22 are gradually misaligned, that is, the lower end of the receiving hopper 22 will gradually abut against the first material stop plate 23, blocking the discharge of the matrix; at the same time, the lower end of the metering barrel 24 is gradually aligned with the second discharge hole 261, that is, the matrix in the metering barrel 24 can be discharged downward from the second discharge hole 261 and the discharge barrel 27. Subsequently, the push cylinder 25 drives the metering barrel 24 back to its original position. The lower end of the metering barrel 24 is once again blocked by the second material stop plate 26, while the upper end is realigned with the lower end of the receiving hopper 22. The matrix in the receiving hopper 22 automatically falls into the metering barrel 24, and no additional switching mechanism is required, allowing for orderly metered material discharge. Thus, the volume of the metering barrel 24 determines the amount of matrix filled each time, and a metering barrel of the required volume can be selected as needed. This matrix filling mechanism, through its mechanical design, effectively achieves quantitative filling of the matrix, with a simple overall structure and enhanced operational stability and efficiency.

[0032] In order to ensure the accuracy of the quantitative barrel 24 moving position, thereby guaranteeing the efficiency of receiving matrix and releasing matrix, guide plates 28 are connected on the opposite sides of the first baffle plate 23, and the second baffle plate 26 is provided with a guide groove 262 that cooperates with the guide plate 28. The guide plate moves along the guide groove and can effectively ensure the accuracy of the quantitative barrel moving position. At the same time, multiple reinforcing connecting rods 29 are connected between the two guide plates 28 to ensure structural strength. Further, the same end of the first baffle plate 23 and the two guide plates 28 is connected to a push plate 210, and the output end of the push cylinder 25 is connected to the push plate 210. The push plate 210 not only provides a stable connection position for the push cylinder, but also improves structural strength. In addition, the upper ends of the push plate 210 and the two guide plates 28 are all higher than the first baffle plate 23, so as to avoid the matrix accidentally overflowing between the receiving hopper 22 and the first baffle plate 23 from being scattered everywhere, and can be regularly cleaned from the opposite end of the first baffle plate 23 and the push plate 28. In order to ensure the efficiency of the quantitative barrel 24 in receiving the matrix, the diameter of the lower outlet of the receiving hopper 22 is larger than the diameters of the first discharge hole 231 and the quantitative barrel 24. Therefore, the receiving hopper does not need to be completely aligned with the first discharge hole and the quantitative barrel, and the quantitative barrel can efficiently receive the matrix.

[0033] like Figure 4 As shown, the discharge barrel 27 includes a conical receiving portion 271 connected to the second baffle plate, and a straight discharge portion 272 connected to the lower end of the conical receiving portion 271. The conical receiving portion 271 is used to ensure the efficiency of the discharge barrel receiving the matrix, and the straight discharge portion 272 is used to ensure the accuracy of filling into the seedling bag or seedling cup. Figure 3 As shown, a telescopic cylinder 273 is slidably connected to the outer portion of the straight tube discharge portion 272. A drive plate 274 is provided on the telescopic cylinder 273. A telescopic cylinder 275 is provided between the drive plate 274 and the filling frame 21. The telescopic cylinder 275 drives the telescopic cylinder 273 to extend downward, thereby allowing the telescopic cylinder 273 to extend into the seedling bag or seedling cup for matrix filling, ensuring filling accuracy and preventing matrix splashing. When the telescopic cylinder 273 is reset upward, it will not interfere with the horizontal transportation of the seedling bag or seedling cup. In order to ensure the stability of the telescopic cylinder's telescopic action, two telescopic guide rods 276 are provided between the drive plate 274 and the second baffle plate 26.

[0034] like Figure 2As shown, in order to effectively control the amount of substrate in the receiving hopper 22 and prevent excessive substrate overflow, a rotary paddle level switch 211 is provided in the receiving hopper 22. The signal output end of the rotary paddle level switch 211 is connected to the controller of the substrate lifting mechanism 1. When the substrate in the receiving hopper 22 submerges the rotary paddle level switch 211, the rotary paddle level switch 211 generates a corresponding signal, which is output to the controller of the substrate lifting mechanism 1, causing the substrate lifting mechanism 1 to suspend feeding. When the substrate in the receiving hopper 22 falls below the rotary paddle level switch 211, a corresponding signal is generated to instruct the substrate lifting mechanism 1 to resume feeding. Thus, an appropriate amount of substrate in the receiving hopper 22 can be stably maintained, ensuring a sufficient supply of substrate while preventing excessive substrate overflow.

[0035] The above is only a preferred embodiment of the present invention, which is one implementation method based on the overall concept of the present invention. The scope of protection of the present invention is not limited to this embodiment. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
