[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to solve the technical problem that the alfalfa is manually cut into the seedling bed 32, the cutting is uneven and the cutting depth is inconsistent, which leads to a large difference in the growth rate of alfalfa, such as Figures 1-10 As shown, the following preferred technical solutions are provided:

[0033] A breeding rack for alfalfa cuttings includes a fixed frame 1. The fixed frame 1 is provided to support and limit a plurality of components. A rotating assembly 2 is provided on the fixed frame 1. Several seedling assemblies 3 are rotatably provided on the rotating assembly 2. Alfalfa cuttings are cultivated on the seedling assemblies 3. The rotating assembly 2 is used to drive the seedling assemblies 3 to rotate, so that the alfalfa on the seedling assemblies 3 is evenly illuminated and grows evenly.

[0034] The fixed frame 1 is provided with a seedling assembly 4. The worker places the processed alfalfa on the seedling assembly 4, which is then transferred to the cutting position by the seedling assembly 4. No manual handling is required. A pair of lifting assemblies 5 are fixedly provided on the fixed frame 1, and the two lifting assemblies 5 are respectively provided on both sides of the seedling assembly 4. When the cutting is completed, the lifting assembly 5 drives many components to rise upward, leaving enough growth space for the alfalfa to prevent affecting the normal growth of the alfalfa. When cutting is needed next time, the lifting assembly 5 drives many components to descend to a suitable cutting position. A cutting assembly 6 is fixedly provided on the lifting assembly 5, and several seedling guide assemblies 7 are also fixedly provided on the lifting assembly 5. There is a The seedling guide assembly 7 is connected to the upper seedling assembly 4, and the cutting assembly 6 then inserts the processed alfalfa into the seedling raising assembly 3 for cultivation. The two lifting assemblies 5 are jointly fixed with a load-bearing frame 8, which is used to limit and bear the weight of the components on the equipment. The lower seedling assembly 9 is fixedly installed on the load-bearing frame 8, and the air collecting assembly 10, the buffer chamber 20 and the water storage assembly 30 are also fixedly provided on the load-bearing frame 8. The water storage assembly 30 and the lower seedling assembly 9 are connected by a water pipe, and the air collecting assembly 10, the buffer chamber 20 and the water storage assembly 30 are connected in turn by an air pipe, and the compression end of the air collecting assembly 10 is fixedly connected to the lower seedling assembly 9.

[0035] During the process of cutting, the worker first places the pre-processed alfalfa on the upper seedling component 4 in order. When the upper seedling component 4 moves the alfalfa with the guide seedling component 7 to a position aligned with the guide seedling component 7, the upper seedling component 4 stops running and is positioned. At this time, the lower seedling component 9 is started to act on the upper seedling component 4, so that the alfalfa in the upper seedling component 4 slides into the guide seedling component 7. Since the cutting component 6 and the guide seedling component 7 are connected, the alfalfa in the guide seedling component 7 slides into the cutting component 6 again, and the cutting component 6 cuts the processed alfalfa onto the seedling raising component 3 for cultivation; in addition, in the process of the lower seedling component 9 acting on the upper seedling component 4, the lower end of the lower seedling component 9 will align with the top of the guide seedling component 7. At the same time, when the lower seedling component 9 is in operation, it will also synchronously drive the gas collecting component 10 to operate and generate compressed gas. The compressed gas enters the interior of the water storage component 30 through the buffer chamber 20 to pressurize the water. Since the water storage component 30 and the lower seedling component 9 are connected by a water pipe, the pressurized water will enter the interior of the lower seedling component 9 through the water pipe, and be sprayed from the lower end of the lower seedling component 9 to the seedling guide component 7, and finally enter the cutting component 6. The water spraying operation mode can not only prevent the alfalfa from being stuck in the process from the seedling guide component 7 to the cutting component 6, but also can directly water the cutted alfalfa during cutting, and no manual watering is required.

[0036] The above-mentioned setting can achieve uniform cutting. Even if alfalfa is stuck in the process of moving from the seedling guide component 7 to the cutting component 6, the water flow through the spraying water can not only flush the stuck alfalfa into the cutting component 6, but also will not cause major damage to the alfalfa, and thus will not have a major impact on the survival rate of the alfalfa.

[0037] The rotating assembly 2 includes a rolling frame 21 rotatably mounted on the fixed frame 1, and a motor 22 is fixedly mounted on the fixed frame 1. The motor 22 and the rolling frame 21 are concentrically arranged, and the output end of the motor 22 is fixedly connected to the side wall of the rolling frame 21.

[0038] The seedling raising assembly 3 includes a plurality of pairs of triangular mounting frames 31 symmetrically rotatably mounted on the side walls of the rolling frame 21 , and a seedling raising bed 32 is fixedly mounted on each pair of triangular mounting frames 31 .

[0039] Treated soil is placed on the seedling bed 32 in advance. The treated alfalfa is cut into the soil on the seedling bed 32 for cultivation through the cutting assembly 6. The motor 1 22 drives the rolling frame 21, the triangular mounting frame 31 and the seedling bed 32 to rotate, so that the alfalfa on the seedling bed 32 is evenly exposed to sunlight, which is conducive to the uniform growth of alfalfa.

[0040] The seedling loading assembly 4 includes a conveyor belt 41 rotatably arranged on the fixed frame 1, and a second motor 42 is fixedly installed on the fixed frame 1. The second motor 42 can drive the conveyor belt 41 to rotate, and the seedling storage assemblies 43 are evenly arranged on the outer surface of the conveyor belt 41.

[0041] The seedling storage assembly 43 includes a seedling storage box 431 fixedly mounted on the outer surface of the conveyor belt 41, a slide groove 432 is provided on the side wall of the seedling storage box 431, a slider 434 is slidably installed inside the slide groove 432, the top surface of the slider 434 and the side wall of the inner cavity of the slide groove 432 are elastically connected by a spring 435, and a baffle 433 is fixedly mounted on the outer wall of the slider 434.

[0042] During the process of grafting alfalfa, the worker places the processed alfalfa in the seedling box 431, and then starts the motor 2 42 to drive the seedling box 431 forward, until the opening of the seedling box 431 is aligned with the seedling guide assembly 7, which is convenient for subsequent seedling placement.

[0043] The lifting assembly 5 includes a pair of electric telescopic columns 51 symmetrically fixedly mounted on the fixing frame 1 , and the output ends of the two electric telescopic columns 51 are fixedly connected to a long plate 52 .

[0044] The cutting assembly 6 includes a pair of electric telescopic columns 61 symmetrically fixedly mounted on the bottom surface of the long plate 52. The output ends of the two electric telescopic columns 61 are jointly fixedly mounted on a limit frame 62. A slide 63 is slidably mounted on the limit frame 62. A number of soil insertion assemblies 65 are fixedly mounted on the slide 63. A pair of electric telescopic columns 64 are also symmetrically fixedly mounted on the side walls of the limit frame 62. The output ends of the two electric telescopic columns 64 are both fixedly connected to the side walls of the limit frame 62.

[0045] The seedling guide assembly 7 includes an L-shaped mounting plate 71 fixedly mounted on the top surface of the long plate 52 , and a seedling receiving tube 72 is fixedly mounted on the upper end of the L-shaped mounting plate 71 .

[0046] The soil insertion assembly 65 includes a temporary storage tube 651 that is fixedly installed on the slide 63. The upper end of the temporary storage tube 651 is connected to the lower end of the seedling receiving tube 72 through a pipe 73. The lower end of the temporary storage tube 651 is movably provided with an opening and closing plate 1 652 and an opening and closing plate 2 654. A connecting rod 1 653 is fixedly installed on the side wall of the upper end of the opening and closing plate 1 652, and the connecting rod 1 653 is rotatably installed on the side wall of the temporary storage tube 651. A connecting rod 2 655 is fixedly installed on the side wall of the upper end of the opening and closing plate 2 654, and the connecting rod 2 655 is rotatably installed on the side wall of the temporary storage tube 651. The connecting rod 1 653 and the connecting rod 2 655 are meshed with teeth. A motor 3 656 is fixedly installed inside the temporary storage tube 651. A driving gear 657 is fixedly installed on the output end of the motor 3 656, and the driving gear 657 and the connecting rod 2 655 are meshed with teeth.

[0047] Specifically, in the process of grafting alfalfa, the worker first places the pre-processed alfalfa in the seedling storage box 431 in order, and then starts the second motor 42 to drive the seedling storage box 431 to be transported forward. After that, when the opening of the seedling storage box 431 is aligned with the seedling receiving tube 72, the second motor 42 stops running, and then starts the lower seedling assembly 9 to act on the baffle 433, so that the baffle 433 and the slider 434 slide downward, thereby making the seedling storage box 431 open. In addition, since the interior of the seedling storage box 431 is tilted, the alfalfa slides from the interior of the seedling storage box 431 to the interior of the seedling receiving tube 72 under the action of its own gravity. Since the pipeline 73 between the seedling receiving tube 72 and the temporary storage tube 651 is connected, the alfalfa in the seedling receiving tube 72 slides into the temporary storage tube 651 for temporary storage.

[0048] Start the electric telescopic column 2 61, drive the limit frame 62, the slide 63, the electric telescopic column 3 64 and the soil insertion assembly 65 to move together in the direction close to the seedling bed 32, until the opening and closing plate 1 652 and the opening and closing plate 2 654 are inserted into the soil to a suitable depth, the electric telescopic column 2 61 stops extending, and then start the motor 3 656 to drive the connecting rod 2 655 to rotate through the driving gear 657. Since the connecting rod 2 655 and the connecting rod 1 653 are meshed, the connecting rod 2 655 and the connecting rod 1 653 will respectively drive the opening and closing plate 2 654 and the opening and closing plate 1 652 to flip in opposite directions, so that the opening and closing plate 1 652 and the opening and closing plate 1 A gap is created between the first and second opening and closing plates 654, allowing the alfalfa to fall into the soil of the nursery bed 32. It should be noted that the gap between the first and second opening and closing plates 652, 654 does not need to be too large, and only needs to be slightly larger than the maximum diameter of the alfalfa. With this arrangement, the soil around the alfalfa will not be pushed too far by the first and second opening and closing plates 652, 654 after the alfalfa is cut. When the first and second opening and closing plates 652, 654 are pulled out of the soil, the soil around the alfalfa will quickly fill the gap, preventing the alfalfa from tilting after the cuttings, which is beneficial to maintaining the stability of the cuttings and thus improving the survival rate of the alfalfa cuttings.

[0049] When one cutting is completed, the electric telescopic column 2 61 is started to drive the limit frame 62, the slide 63, the electric telescopic column 3 64 and the soil inserting assembly 65 to reset upward, and then the electric telescopic column 3 64 is started again to drive the slide 63 and the soil inserting assembly 65 to change positions on the limit frame 62 for the next cutting at a different position.

[0050] The above settings can realize automatic cutting of alfalfa, which not only reduces the labor intensity of workers, but also can achieve uniform cutting and keep the cutting depth consistent, thereby controlling the difference in alfalfa growth rate within a smaller range, which is conducive to subsequent large-scale transplanting.

[0051] In order to solve the technical problem that alfalfa is stuck inside the pipe 73 during the process from the seedling tube 72 to the temporary storage tube 651, as shown in FIG. Figure 1-Figure 3 、 Figure 5 and Figure 7-8 As shown, the following preferred technical solutions are provided:

[0052] The seedling lowering assembly 9 includes four electric telescopic columns 91 symmetrically fixedly mounted on the load-bearing frame 8. The output ends of the two electric telescopic columns 91 are jointly fixedly mounted with a lifting plate 92. A number of injection heads 93 are fixedly mounted on the lifting plate 92. The injection head 93 is concentrically arranged with the seedling receiving tube 72. A slide groove 94 is provided on the side wall of the injection head 93. A downward pressing piece 95 is slidably mounted inside the slide groove 94. The top surface of the downward pressing piece 95 and the side wall of the inner cavity of the slide groove 94 are elastically connected by a spring 96.

[0053] The gas collecting assembly 10 includes a gas collecting cylinder 101 fixedly mounted on the load-bearing frame 8, a piston is built into the interior of the gas collecting cylinder 101, a compression rod 102 is fixedly mounted on the piston, the compression rod 102 is fixedly connected to the extended end of the electric telescopic column 91 through a connecting seat 103, the lower end of the gas collecting cylinder 101 is connected to a one-way air inlet valve 104 and a one-way air outlet valve 105 fixedly mounted thereon, and the one-way air outlet valve 105 is connected to the buffer chamber 20 through an air pipe.

[0054] The water storage assembly 30 includes a water tank 301 fixedly mounted on the load-bearing frame 8 , and a subsidiary water tank 302 is fixedly mounted on the lower end of the water tank 301 , and the subsidiary water tank 302 is connected to a plurality of spray heads 93 through water pipes.

[0055] Specifically, when the opening of the seedling storage box 431 is aligned with the seedling receiving tube 72, the electric telescopic column 4 91 is started to drive the injection head 93, the pressing piece 95 and the spring 2 96 to move downward synchronously through the lifting plate 92, and the lower end of the injection head 93 will be embedded with the top of the seedling receiving tube 72. At the same time, when the electric telescopic column 4 91 is extended, it will also drive the piston in the gas collecting cylinder 101 to move through the connecting seat 103 and the compression rod 102, and generate compressed gas inside the gas collecting cylinder 101. The compressed gas passes through the one-way outlet valve 105, the air pipe and the buffer Chamber 20 enters the interior of the water tank 301 and pressurizes the water. Since the auxiliary water tank 302 and several injection heads 93 are connected through water pipes, the pressurized water will enter the interior of the injection head 93 through the auxiliary water tank 302 and the water pipe, and be sprayed from the lower end of the injection head 93 to the seedling tube 72, and finally enter the temporary storage tube 651 through the pipe 73. When a gap is generated between the opening and closing plate 1 652 and the opening and closing plate 2 654, alfalfa and water will enter the soil together. Watering is completed at the same time as the cuttings are planted, and there is no need for manual watering.

[0056] By adopting the above-mentioned water spraying operation mode, even if the alfalfa is stuck in the pipe 73 during the process from the seedling tube 72 to the temporary storage tube 651, the water flow through the spraying water can not only flush the stuck alfalfa into the temporary storage tube 651, but also will not cause major damage to the alfalfa, and thus will not have a major impact on the survival rate of the alfalfa. In addition, the grafted alfalfa can be directly watered during grafting, and there is no need for manual watering, which saves manpower and is highly practical.

[0057] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
