Description

Technical Field

[0001] The utility model belongs to the technical field of seed processing equipment, in particular to a device for promoting germination of alfalfa seeds. Background Art

[0002] Alfalfa is a high-quality forage grass, rich in protein and nutrition, suitable for livestock, especially for cattle feed. Alfalfa has the ability to coexist with some rhizobia, which help fix nitrogen and convert atmospheric nitrogen into a form that can be used by plants. Therefore, alfalfa is also often used to improve soil. Alfalfa can be planted in farmland as a green manure plant to increase soil fertility and organic matter content. Due to the hardness of alfalfa seeds, the germination rate is low, the emergence of seedlings is uneven in the later stage, and the growth is delayed. Traditional field planting cannot break the hardness of yellow alfalfa seeds due to soil covering, and it is difficult to germinate in the later stage, which makes it difficult to promote and plant alfalfa on a large scale. In order to solve the problem of low germination rate of alfalfa seeds, alfalfa seeds can be allowed to germinate first, and then they can be cultivated and transplanted.

[0003] However, in the prior art, the cultivation method of alfalfa seeds requires the alfalfa seeds to be shelled first in order to ensure the normal germination of the seeds. The commonly used shelling methods include soaking and grinding. The soaking method takes a long time, and the seeds are prone to excessive water absorption and rot. When grinding and shelling, the hardness of the seed shells is different, and the shelled seeds and the unshelled seeds are mixed together, which is easy to damage the seeds. To this end, we provide an alfalfa seed germination promotion device to solve the above problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-5 The utility model is a device for promoting germination of alfalfa seeds, comprising a support tube 1, a filter cartridge 2 is arranged at the bottom of the support tube 1, and a preheating tank 3 is arranged at the bottom of the filter cartridge 2;

[0030] A shelling assembly is provided on one side of the support tube 1, and the shelling assembly includes a cooling tube 4, the bottom of the cooling tube 4 is connected to a compression refrigerator 5, a transmission rod 6 is provided inside the cooling tube 4, and isolation plugs 7 are sleeved on both sides of the surface of the transmission rod 6, and a heater 8 is fixedly connected inside the preheating tank 3, and the seeds are shelled by the shelling assembly;

[0031] A driving assembly is arranged inside the cooling tube 4, and the processing position of the seeds is adjusted by the driving assembly.

[0032] Specifically, a filter net is fixed inside the filter cylinder 2 to isolate the seeds from the warm water. After the seeds are soaked, the seeds can be filtered and dried. Warm water is injected into the preheating tank 3 to soak the seeds. The refrigeration compressor uses the compression and expansion of gas to achieve the refrigeration effect. First, the refrigerant enters the refrigeration compressor in a low-pressure and low-temperature state, and then the piston or screw mechanism in the refrigeration compressor mechanically compresses the refrigerant to convert it into a high-pressure and high-temperature gas. The high-pressure gas is transported to the condenser through a pipeline to cool and release heat, so that the refrigerant is condensed into a liquid state, and the liquid coolant is injected into the circulation pipe inside the cooling pipe 4 to achieve the effect of refrigerating the seeds. Specific embodiment 2

[0034] See also Figure 1-5 On the basis of the specific embodiment 1, the driving assembly includes a driving motor 9, the driving motor 9 is fixed to one side of the isolation plug 7, a mixing blade 10 is fixedly connected to the surface of the transmission rod 6, a first hydraulic rod 11 is fixedly connected to one side of the cooling pipe 4, one end of the transmission rod 6 is fixedly connected to the output end of the driving motor 9, the output end of the first hydraulic rod 11 is fixedly connected to the isolation plug 7, a bottom plate 12 is provided at the bottom of the preheating tank 3, a pillar 13 is fixedly connected to the top of the bottom plate 12, and the top of the pillar 13 is fixedly connected to the cooling pipe 4.

[0035] Specifically, the space between the two groups of isolation plugs 7 can be used to store seeds and at the same time isolate cold air. The heater 8 can preheat the water in the preheating tank 3 to keep the water temperature moderately between 5°C and 25°C. This step helps to accelerate the germination of the seeds. The drive motor 9 can drive the transmission rod 6 and the mixing blades 10 to rotate and turn the seeds, which can improve the cooling uniformity of the seeds. Specific embodiment three

[0037] See also Figure 1-5 On the basis of the specific embodiment 1 and the specific embodiment 2, a bracket 14 is fixedly connected to the surface of the pillar 13, a second hydraulic rod 15 is fixedly connected to the top of the bracket 14, the bottom output end of the second hydraulic rod 15 is fixedly connected to the preheating tank 3, a feed pipe 16 is connected to the top of the cooling pipe 4, a sealing cover is threadedly connected to the surface of the feed pipe 16, a support frame 17 is provided at the bottom of the filter cartridge 2, the top of the support frame 17 is fixedly connected to the support pipe 1, a first sealing ring 18 is fixedly connected to the surface of the isolation plug 7, and a second sealing ring 19 is fixedly connected to the surface of the support pipe 1.

[0038] Specifically; the first hydraulic rod 11 can adjust the positions of the two groups of isolation plugs 7 to facilitate the transportation of cooled seeds. The second hydraulic rod 15 can drive the preheating tank 3 to move and control the soaking time of the seeds. The feed pipe 16 can facilitate the transportation of seed raw materials in the cooling tube 4. The support frame 17 can facilitate the placement of the filter cartridge 2. The first sealing ring 18 can increase the sealing effect between the isolation plug 7 and the inner wall of the cooling tube 4. The second sealing ring 19 can increase the sealing effect between the preheating tank 3 and the support tube 1.

[0039] The working principle of the utility model is as follows: the staff transports the alfalfa seeds to the inside of the cooling tube 4 through the feed pipe 16, isolates the alfalfa seeds through the two groups of isolation plugs 7, and then starts the compression refrigerator 5 to cool the alfalfa seeds in the cooling tube 4, cools the alfalfa seeds to about -5°C, controls the time length to be 2 to 4 hours, and can effectively shrink the seed shell. After the freezing is completed, the first hydraulic rod 11 is started, and the first hydraulic rod 11 cooperates with the transmission rod 6 to drive the two groups of isolation plugs 7 to move, pushes the seeds to the right, and makes the seeds fall into the support tube 1 and enter the filter cylinder 2. Figure 3 As shown, the heater 8 is then started to heat the water in the preheating tank 3 to raise the water temperature to between 15°C and 25°C. The alternation of hot and cold can cause the shell on the surface of the seeds to shrink and expand, which is helpful for cracking;

[0040] At the same time, the support tube 1 is between 5°C and 25°C. Within this temperature range, the germination rate and growth rate of alfalfa seeds will be ideal, which can improve their germination rate. After the shell is broken, the second hydraulic rod 15 is started, and the second hydraulic rod 15 drives the preheating tank 3 to move downward, so that the seeds in the filter cylinder 2 fall off the warm water and filter the seeds dry. Figure 4 As shown, the seedling raising effect is improved.
