Description

Technical Field

[0001] The utility model relates to the technical field of soil covering for seedling raising and sowing machines, in particular to a seedling raising and sowing machine with a seedling tray and uniform soil covering. Background Art

[0002] The rice seedling tray seeding machine, as an agricultural machinery designed for rice seedling cultivation, has significantly improved the efficiency and quality of rice seedling cultivation. It integrates soil spreading, watering, sowing, and covering soil, and is suitable for the sowing needs of conventional rice and hybrid rice. It is an indispensable equipment for factory-based rice seedling cultivation and machine transplanting operations.

[0003] The soil covering device plays a vital role in the use of the seedling tray seeding machine. The device evenly covers the soil from the soil covering box to the seedling tray through precise mechanical operation. However, in actual operation, the soil lumps often plague the soil covering device. These lumps are easy to form blockages at the discharge port, hindering the normal flow of soil, and thus causing uneven soil covering or failure to cover soil.

[0004] In addition, if the operator fails to adequately stir or screen the soil when filling, large pieces of soil or impurities may enter the soil cover box. These large pieces of soil and impurities will also interfere with the normal operation of the soil cover device and increase the risk of discharge blockage. At the same time, if the soil cover box is not regularly cleaned and maintained, too much residual soil may accumulate in the box, further exacerbating the blockage problem and affecting the performance and stability of the soil cover device.

[0005] Therefore, in order to ensure the smooth operation of the soil covering device of the seedling tray seeding machine, the operator needs to pay attention to the mixing and screening of the soil to prevent large pieces of soil and impurities from entering the soil covering box. At the same time, the soil covering box should be cleaned and maintained regularly to remove residual soil in time to ensure that the soil covering device always maintains a good working condition.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 - Figure 4 As shown, a seeding tray seeding machine with uniform soil covering is characterized in that it can achieve uniform soil covering operation. The seeding machine mainly includes a bracket 1, a moving wheel 2, a connecting frame 3, a push handle 5, a soil covering box 6, a discharge pipe 12, a hose 13, a feed pipe 14, and a soil covering plow 15 and other core components.

[0028] The bracket 1 serves as the supporting structure of the entire machine, and a moving wheel 2 is installed at its lower end to facilitate the flexible movement of the machine. At the rear end of the bracket 1, two push handles 5 are designed, and a soil covering box 6 is firmly fixed between them by bolts. The upper end of the soil covering box 6 is a soil covering bin 8 for storing soil to be used. On the side wall of the soil covering box 6, a stirring component 9 is installed, which is connected to the moving wheel 2 through a transmission device 4. When the seeder is pushed forward, the movement of the moving wheel 2 will drive the stirring component 9 to rotate through the transmission device 4, and then the soil in the soil covering bin 8 is evenly mixed.

[0029] The design of the stirring assembly 9 is very clever, and it includes a stirring rod and a stirring wheel. The stirring rod is mounted on the soil covering box 6, and a bearing is provided at the connection between the two to ensure that the stirring rod can rotate smoothly. On the stirring rod, multiple stirring wheels are evenly distributed, and they work together to enable the soil to be fully stirred and mixed.

[0030] The lower end of the soil covering box 6 is designed with a discharge pipe 12, which is designed as an integral part of the soil covering box 6 to ensure that the soil can flow out of the soil covering bin 8 smoothly. The discharge pipe 12 is connected to the feed pipe 14 through a hose 13, so that the soil can be transported to the position where soil covering is required through the hose 13 and the feed pipe 14. The lower end of the feed pipe 14 is installed with a soil covering plow 15, which is welded and fixed to the feed pipe 14 to ensure stable operation during the soil covering process. The soil covering plow 15 and the feed pipe 14 work together to achieve precise soil covering operation.

[0031] In order to facilitate maintenance and replacement of parts, a disassembly cover 7 is also installed on the upper end of the soil covering box 6 through a locking device. The lower end of the disassembly cover 7 is connected to a crushing wheel 10 through a mounting frame 11. These crushing wheels 10 and the stirring assembly 9 are staggered in design. When they work at the same time, the lumps in the soil can be crushed to further improve the uniformity of the soil.

[0032] In addition, the design of the push handle 5 also fully considers the humanization factor. They are placed on both sides of the bracket 1 and are firmly fixed by bolts. The push handle 5 adopts an oblique design, which makes it easier for the operator to push the seeder. At the same time, the soil covering box 6 and the push handle 5 are also fixed by bolts to ensure that the structure of the entire machine is stable and reliable.

[0033] The design of the connecting frame 3 also takes into full consideration stability and convenience. It is mounted on the soil covering box 6 by bolts and is firmly connected to the feed pipe 14. This connection method is not only simple and easy, but also can ensure the stability of the feed pipe 14 during the soil covering process.

[0034] The seedling tray seeding machine achieves the goal of uniform soil covering through its unique design and sophisticated combination of components. Whether it is the uniform mixing effect of the stirring assembly 9 or the precise soil covering operation of the soil covering plow 15 and the feed pipe 14, the excellent performance of the machine in seedling tray seeding is demonstrated.

[0035] Soil covering process: The seeder is pushed to the working area by the moving wheel 2. At this time, the movement of the moving wheel 2 drives the stirring assembly 9 to start working through the transmission device 4. The stirring rod and the stirring wheel in the stirring assembly 9 rotate rapidly in the soil covering bin 8 to fully mix and stir the soil evenly. At the same time, the crushing wheel 10 crushes the lumps in the soil to ensure the uniformity and fineness of the soil.

[0036] The soil flows out through the discharge pipe 12 at the lower end of the soil covering box 6 and is transported to the conveying pipe 14 through the hose 13. At this time, the soil covering plow 15, as a key component, begins to cover the seedling tray with soil. The soil covering plow 15 can ensure that the soil is evenly covered on the seedling tray through precise design and position adjustment, achieving an ideal soil covering thickness and uniformity.

[0037] During the entire soil covering process, the push handle 5 provides the operator with a comfortable pushing angle and strength, making the operation of the seed drill more convenient and labor-saving. At the same time, the connecting frame 3 ensures the stability and reliability of the feed pipe 14 to prevent shaking or deviation during the soil covering process.

[0038] Through the precise operation of the covering plough 15 and the stable delivery of the feed pipe 14, the soil on the seedling tray is evenly covered, achieving the goal of covering the seedlings in the seeding machine. The entire covering process is efficient and accurate, greatly improving the quality and efficiency of seedling tray seeding.

[0039] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0040] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
