Description

Technical Field

[0001] The invention relates to the technical field of seedling tray sowing equipment, in particular to a seedling tray sowing equipment for agricultural seedling cultivation. Background Art

[0002] The plug tray, also known as the seedling tray, has become an important tool in the factory seed production process. Whether it is flowers or vegetables, plug tray seedling cultivation is the most fundamental change in modern horticulture, which provides a guarantee for fast and large-scale production. The materials used to make plug trays are generally polystyrene foam, polystyrene, polyvinyl chloride and polypropylene. The manufacturing methods include blow molding and injection molding. Generally, vegetable and ornamental plant seedling plug trays are made of polystyrene.

[0003] In the prior art, a Chinese patent with publication number "CN112616501B" discloses a seeding tray sowing device for agricultural seedling cultivation. The seeding soil is placed in a loading frame, the seeding tray is placed on a conveyor belt, and the servo motor is started. When the connecting tooth is driven by the rotating shaft to engage with the connecting gear, the power wheel is rotated through the transmission belt group, and the conveyor belt moves accordingly, so that the seedling tray moves. When the seedling tray moves to the bottom of the loading frame, the connecting tooth is not engaged with the connecting gear at this time. The rotating shaft drives the transmission tooth to rotate through the power belt group and the linkage belt group. The transmission tooth is engaged with the rack below the linkage rack at this time, driving the baffle to move so that the seedling soil falls into the seedling tray. When the transmission tooth is engaged with the rack above the linkage rack, the baffle is driven to reset, so that the seedling soil stops falling. When the transmission tooth is not engaged with the linkage rack, the connecting tooth is engaged with the connecting gear at this time, which solves the problem that the existing seedling tray needs to be manually sown, and workers need to do repetitive work many times, which wastes labor and has low work efficiency.

[0004] When sowing in existing seedling trays, due to the low efficiency of manual sowing, seedling tray sowing equipment is usually used for sowing. As in the scheme described above, the conveying mechanism and the feeding mechanism can only complete the automatic loading of soil, and the seeds cannot be automatically sown in the seedling tray. Although the seeds can be sown on the seedling tray manually, manual sowing not only wastes manpower, but also makes it difficult to ensure the uniformity and accuracy of seed sowing, which may lead to uneven distribution of seeds and affect the growth and germination of seeds. Therefore, the present invention proposes a seedling tray sowing equipment for agricultural seedling cultivation to solve the above-mentioned problems. Summary of the invention

[0045] Embodiment three:

[0046] See also Figure 1-11 On the basis of the first embodiment, a conveying assembly is arranged inside the two bracket plates 1, and a pressing assembly is arranged on the conveying assembly. A plurality of pressing heads 5 are arranged on the pressing assembly, and the soil and seeds on the seedling tray body 2 are slightly pressed by the pressing heads 5. The pressing assembly includes a polygonal cam 29 fixedly mounted on the output shaft 26 and two I-shaped plates 30 and a stabilizing plate 48 fixedly mounted between the two mud storage boxes 3 and the seed storage box 4. The position of the I-shaped plate 30 is above the stabilizing plate 48, and the lower end surfaces of the two I-shaped plates 30 are fixedly connected with A pressure spring 31, one end of the pressure spring 31 away from the I-plate 30 is fixedly connected to a lifting plate 32, and a pressure plate 33 is fixedly connected to the two lifting plates 32.

This method facilitates slight pressing of the seedling tray body 2 when the first discharge of soil and seedling seeds is completed, so that the contact effect between the soil and seedling seeds in the seedling tray body 2 is better, thereby improving the absorption and growth ability of the seeds.

[0048] Embodiment 4:

[0049] See also Figure 1-11On the basis of the third embodiment, a lifting assembly is further provided on the conveying assembly, and a pressing assembly is provided on the lifting assembly, through which the mud in the mud storage box 3 will not be blocked in the through groove 6, and the lifting assembly includes a plurality of squeezing plates 34 fixedly installed on the polygonal cam 29 and a positioning plate 35 fixedly installed on the mud storage box 3, a positioning slide bar 36 is slidably connected to the positioning plate 35, and a fixing plate 37 is fixedly connected to the bottom end of the positioning slide bar 36, wherein the cross-sectional shape of the positioning slide bar 36 is T-shaped, so as to ensure that the positioning slide bar 36 will not fall off when sliding on the positioning plate 35, and an squeezing spring 38 is fixedly installed on the upper end surface of the fixing plate 37, and one end of the squeezing spring 38 away from the fixing plate 37 is fixedly connected to the lower end surface of the positioning plate 35, and a fixing plate 37 is fixedly installed on the fixing plate 37 A positioning slide 39 is provided, to which a lifting horizontal plate 40 is fixedly connected, and the lifting horizontal plate 40 is slidably connected to the end of the extrusion plate 34, and a stabilizing frame plate 41 is fixedly connected to the mud storage box 3, and the positioning slide 39 is slidably connected to the stabilizing frame plate 41, and the pressing assembly includes a rotating block 42 rotatably connected to the lower end surface of the fixed plate 37 and a support plate 43 fixedly installed inside the mud storage box 3, and a screw rod 44 is fixedly connected to the rotating block 42, and one end of the screw rod 44 away from the rotating block 42 passes through the support plate 43, and is fixedly connected to a conical conveying roller 45, and the screw rod 44 and the support plate 43 are movably connected, wherein the extrusion plate 34 is located on the outside of the polygonal cam 29 and inside the U-shaped plate 27, to ensure that the extrusion plate 34 can rotate normally following the polygonal cam 29.

[0050] In this embodiment, when the polygonal cam 29 rotates, it will drive the extrusion plate 34 to rotate synchronously. Through the continuous lifting of the lifting cross plate 40 by the extrusion plate 34, the fixed plate 37 will be in a continuously rising state through the positioning slide plate 39 and the elastic force of the extrusion spring 38. Then, through the cooperation between the rotating block 42 on the fixed plate 37 and the spiral rod 44 and the positioning plate 35, the conveying roller 45 is in a lifting state while rotating. Through the downward pressure and rotation of the conveying roller 45, the soil in the mud storage box 3 will enter the corresponding first quantitative hole 11 through the through groove 6, effectively avoiding the blockage of soil in the through groove 6 and affecting the normal use of the equipment.

[0051] Working principle:

[0052] When in use, the fourth motor 28 uses the output shaft 26 to drive the conveying roller 25 to rotate, and the conveying roller 25 is used to make the conveyor belt 47 in a transmission state, and then the seedling tray body 2 is placed on the conveyor belt 47 for transportation, and the first motor 9 drives the first rotating roller 10 to rotate. When the first rotating roller 10 is driven to rotate a specified angle, the first quantitative hole 11 on the first rotating roller 10 will be in the same vertical direction as the through groove 6 on the mud storage box 3, and the soil in the mud storage box 3 will directly fall into the first quantitative hole 11. After the first quantitative hole 11 filled with soil rotates 180 degrees, it will be connected with the outlet 7, and the soil in the first quantitative hole 11 will directly fall into the seedling hole of the seedling tray body 2. The first quantitative hole 11 on the first rotating roller 10 is used to facilitate the soil in the mud storage cavity to be quantitatively discharged into the seedling tray body 2 in two times;

[0053] When the first soil discharge is completed, the second rotating roller 23 is driven to rotate by the third motor 22, so that the second quantitative hole 24 on the second rotating roller 23 and the through slot 6 in the seed storage box 4 are in the same vertical direction, and the seeds in the seed storage box 4 will directly fall into the second quantitative hole 24. When the second quantitative hole 24 containing the seeds rotates 180 degrees, it will be connected with the outlet 7, and the seeds in the second quantitative hole 24 will directly fall into the seedling hole of the seedling tray body 2, thereby enhancing the germination and growth of the seeds.

[0054] When discharging soil from different seedling trays, in order to ensure the amount of soil discharged, the second motor 14 drives the driving roller 15 to rotate, and the convex block 16 on the driving roller 15 is used to squeeze the arc block 19. When the arc block 19 is squeezed, it will pass through the limit of the annular groove 13, and the adjusting rod 18 is used to adjust the position of the circular plate 17 in the first quantitative hole 11, so as to adjust the volume of the first quantitative hole 11, effectively ensuring that the soil is evenly and fully distributed, and improving the growth effect of the seedlings;

[0055] When the conveyor belt 47 drives the seedling tray to be transported, the multi-angle cam 29 on the output shaft 26 is in intermittent contact with the pressure plate 33, and the pressure plate 33 drives the pressing head 5 on the lifting plate 32 to press the seedling hole on the seedling tray body 2. This method is convenient for slightly pressing the seedling tray body 2 when the first discharge of soil and the discharge of seedling seeds are completed, so that the contact effect between the soil and the seedling seeds in the seedling tray body 2 is better, and the absorption and growth ability of the seeds are improved;

[0056] When the polygonal cam 29 rotates, it will drive the extrusion plate 34 to rotate synchronously. Through the continuous lifting of the lifting cross plate 40 by the extrusion plate 34, the fixed plate 37 will be in a continuously rising state through the limited sliding of the positioning slide plate 39 on the stabilizing plate and the elastic force of the extrusion spring 38. At this time, the fixed plate 37 will be in a stably raised state through the limitation of the mud storage box 3 and the limitation of the positioning slide bar 36, and then through the cooperation between the rotating block 42 on the fixed plate 37 and the spiral rod 44 and the positioning plate 35, the conveying roller 45 is in a lifting state while rotating. Through the downward pressure and rotation of the conveying roller 45, the mud in the mud storage box 3 will enter the corresponding first quantitative hole 11 through the through groove 6, effectively avoiding the mud from being blocked in the through groove 6 and affecting the normal use of the equipment.
