Except for the power transmission bracket 32, a long shaft 14 is connected between the short shafts 8 on both sides of the other brackets 2 through a coupling. The scissor-type connecting rod assembly 5 includes a first scissor-type connecting rod 11 and a second scissor-type connecting rod 12 arranged between the upper and lower adjacent brackets 2, the upper end of the first scissor-type connecting rod 11 is connected to the short shaft 8 of the upper bracket 2, the lower end of the first scissor-type connecting rod 11 is connected to the connecting rod 6 of the lower bracket 2, the upper end of the second scissor-type connecting rod 12 is connected to the connecting rod 6 of the upper bracket 2, and the lower end of the second scissor-type connecting rod 12 is connected to the short shaft 8 of the lower bracket 2; a connecting shaft 13 is connected at the intersection of the first scissor-type connecting rod 11 and the second scissor-type connecting rod 12. Through the scissor-type connecting rod assembly 5, the lifting function of the seedbed 4 is realized, so that the seedbed 4 can be adjusted up and down as needed, which improves the space utilization rate and is easy to manage and operate. In addition, this structure also enhances the stability and reliability of the entire device, making the growth environment of the plant more stable. As attached Figure 6As shown, the short shafts 8 on both sides of the power transmission bracket 32 ​​are fixedly connected with the transmission nuts 9. The power transmission bracket 32 ​​is provided with a bevel gear transmission assembly 10, which is threadedly matched with the transmission nut 9, and the scissor-type connecting rod assembly 5 is driven through the bevel gear shaft and the transmission nut 9. The bevel gear transmission assembly 10 is arranged below the seedling bed 4, and the bevel gear transmission assembly 10 includes a first bevel gear shaft 15, and the bevel gear of the first bevel gear shaft 15 is meshed with the second bevel gear shaft 16 and the third bevel gear shaft 17, and the second bevel gear shaft 16 is arranged opposite to the third bevel gear shaft 17.

The bevel gear transmission assembly 10 is arranged below the seedbed 4, making the entire structure more compact and reducing space occupation.

[0028] The design of the support frame 1 is mainly designed and manufactured in a way that combines steel plates and steel profiles. In the process of connecting with various components, a flat plate with a relatively flat surface is usually used for connection. Its thickness is controllable, which is convenient for installation. The main body of the support frame 1 generally selects a pipe profile structure with a hollow middle, light weight, and thin walls. It has the advantages of light weight and high strength, and can meet the installation and connection of various components of the multi-layer seedling bed in the plant factory and the actual lifting and adjustment operations, preventing major damage to the equipment during use, and meeting actual use needs. The support frame 1 is provided with 4 vertically arranged support beams, and at the same time, the horizontal support beams are connected by welding around the top of the 4 support beams. The whole structure is square in shape, which is convenient for providing sufficient support for the entire seedling bed 4. The bracket 3 is made of 1060 aluminum alloy with a density of 2.7g / cm 3 , the allowable stress of the metal is 200MP, and the safety factor is 1.5.

[0029] How it works

[0030] When the handle 24 is manually rotated, the bevel gear assembly 10 is driven to rotate, so that the first bevel gear shaft 15 rotates. Since the second bevel gear shaft 16 and the third bevel gear shaft 17 are meshed with the first bevel gear shaft 15, the second bevel gear shaft 16 and the third bevel gear shaft 17 also start to rotate under the rotation of the first bevel gear shaft 15. Since the second bevel gear shaft 16 is meshed with the fourth bevel gear shaft 18, and the third bevel gear shaft 17 is meshed with the fifth bevel gear shaft 19, the rotation of the first bevel gear shaft 15 can drive the fourth bevel gear shaft 18 and the fifth bevel gear shaft 19 to rotate, so that the transmission nut 9 matched with the fourth bevel gear shaft 18 and the fifth bevel gear shaft 19 rotates on the thread of the shaft, driving the short shaft 8 to slide in the slide groove 7, so that the scissor-type connecting rod assembly 5 drives the seedling bed 4 to rise and fall. Due to the arrangement of the bracket 2, the scissor-type connecting rod assembly 5, the bevel gear transmission assembly 10 and the connecting shaft 13, when the second-layer power transmission bracket 3 is raised and lowered, all brackets 2 and the seedling bed 4 can be raised and lowered synchronously.

[0031] In summary, the utility model can realize the lifting and lowering of the multi-layer seedling bed and has the advantages of simple structure and convenient operation.
