Description

Technical Field

[0001] This utility model relates to the field of rice production technology, and in particular to a rice seed germination device. Background Technology

[0002] The main purpose of soaking and germinating rice seeds is to meet the conditions for seed germination, improve germination rate and vigor, reduce the occurrence of pests and diseases, and cultivate strong seedlings. Soaking rice seeds allows them to absorb water and swell, softening the seed coat and promoting germination. This process accelerates the activity of enzymes inside the seed, decomposing stored substances and providing nutrients for germination. Simultaneously, soaking removes weed seeds, impurities, insect galls, and diseased grains, improving sowing quality. Furthermore, disinfectants can be added during soaking to kill pathogens carried by the rice seeds.

[0003] Because there are many seeds, they are prone to piling up. This can lead to some seeds being over-soaked while others are under-soaked, and it can also cause uneven draining during the drying process, thus affecting the soaking and germination effect of the seeds. Utility Model Content

[0031] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figure 1 and Figure 2As shown, this embodiment discloses a rice seed germination device, including a shell 1. A seed soaking tank 2 is located at the bottom of the shell 1, and a filter basket 3 for placing seeds is located above the seed soaking tank 2. The filter basket 3 is movably connected to a movable platform 5 via a shaking mechanism 4. In this embodiment, the shell 1 is equipped with a door 1-1, a water inlet valve 1-2, a water outlet valve 1-3, and a thermometer 1-4. Both the water inlet valve 1-2 and the water outlet valve 1-3 are connected to the seed soaking tank 2. The probe of the thermometer 1-4 is connected to the inside of the seed soaking tank 2, and the thermometer 1-4 is used to detect the temperature of the liquid inside the seed soaking tank 2. Furthermore, a vent with a valve is provided on the inner wall at the upper part of the shell 1. Water is injected into the seed soaking tank 2 via the water inlet valve 1-2, and the filter basket 3 is moved into the seed soaking tank 2 by controlling the movement of the movable platform 5 for seed soaking. In this embodiment, the side walls of the seed soaking tank 2 are insulated with heat-insulating material.

[0033] A scraping assembly 6 is installed inside the housing 1, located above the filter basket 3. The scraping assembly 6 includes a drive unit 6-1 fixedly connected to the inner wall of the housing 1. The drive unit 6-1 has a downward-facing telescopic part 6-2. A slot 5-1 is provided on the movable platform 5, through which the telescopic part 6-2 can move. A scraping rake 6-3 is located at the bottom end of the telescopic part 6-2, and the scraping rake 6-3 contacts and engages with the filter basket 3. The telescopic part 6-2 allows the scraping rake 6-3 to extend into the filter basket 3, and the drive unit 6-1 allows the scraping rake 6-3 to scrape the seeds, facilitating seed turning and leveling.

[0034] like Figure 3 As shown, in this embodiment, as an implementation of the movable platform 5 moving up and down, a first electric push rod 7 is fixedly connected to the inner wall of the top of the housing 1, and the telescopic end of the first electric push rod 7 is fixedly connected to the movable platform 5. By controlling the extension of the telescopic end of the first electric push rod 7, the movable platform 5 can be moved downward, thereby causing the filter basket 3 to fall into the soaking tank 2 for soaking. When the soaking time reaches the required time, the telescopic end of the first electric push rod 7 is retracted, causing the filter basket 3 to move upward and detach from the soaking tank 2 for the draining process.

[0035] like Figures 2 to 5As shown, the shaking mechanism 4 includes a first motor 4-1, a guide rod 4-2, and a hinge rod 4-3. The first motor 4-1 is fixedly mounted on both sides of the movable platform 5. A disc 4-4 is fixedly connected to the output end of the first motor 4-1. The disc 4-4 is fixedly connected to one end of a fixed rod 4-5 near the circumference. A limit post 4-6 is provided at the other end of the fixed rod 4-5. One end of the guide rod 4-2 is fixedly connected to the side frame of the filter basket 3, and the guide rod 4-2 is arranged perpendicular to the filter basket 3. A groove 4-7 is provided on the side of the guide rod 4-2 away from the filter basket 3, and the limit post 4-6 is slidably connected in the groove 4-7. It should be noted that the length of the fixed rod 4-5 should not be too long, and the rotation amplitude of the hinge rod 4-3 should not exceed 30 degrees to avoid excessive shaking of the filter basket 3 and impact with the seed soaking box 2.

[0036] In this embodiment, four hinge rods 4-3 are provided. One end of the hinge rod 4-3 is rotatably connected to the two ends of the two sides of the movable platform 5, and the other end of the hinge rod 4-3 is rotatably connected to the two ends of the side frames of the filter basket 3.

[0037] The filter basket 3 is movably connected to the movable platform 5 via a hinge rod 4-3. When the first motor 4-1 rotates, the fixed rod 4-5 and the limiting post 4-6 begin to rotate. The limiting post 4-6 can move up and down within the sliding groove 4-7, but is restricted in the horizontal direction. Therefore, when the limiting post 4-6 rotates around the motor output shaft, it will cause the guide rod 4-2 to shake in the horizontal direction. The bottom end of the guide rod 4-2 is fixedly connected to the filter basket 3, thereby causing the entire filter basket 3 to shake. When the filter basket 3 is soaking seeds in the seed soaking tank 2, the first motor 4-1 and the guide rod 4-2 can be used to shake the filter basket 3, thereby causing the seeds to be dispersed in the water and preventing uneven soaking due to seed accumulation. At the same time, during the draining process, the shaking of the filter basket 3 can also be used to ensure more thorough drainage. It should be noted that in this embodiment, the first motor 4-1 is a motor of the same model and specifications, so as to facilitate the control of the two motors to make them rotate synchronously, or a dual-motor synchronous controller (such as the S6G15S of the Ouneng brand) can be used for control. The dual-motor synchronous control technology is an existing technology and will not be described in detail here.

[0038] like Figure 6As shown, the drive unit 6-1 includes a second motor 6-1-1, which is fixedly connected to the housing 1 via a frame. A reciprocating screw 6-1-2 is provided at the output end of the second motor 6-1-1, and the reciprocating screw 6-1-2 is slidably connected to a slider 6-1-3. Both ends of the slider 6-1-3 have circular holes that are slidably connected to a guide rod 6-1-4, which is fixedly installed inside the housing 1. The rotation of the second motor 6-1-1 drives the reciprocating screw 6-1-2 to rotate. The reciprocating screw 6-1-2 has two threaded grooves with the same pitch but opposite directions, connected at both ends by a transition curve. Through the rotation of the reciprocating screw 6-1-2, the side of the helical groove pushes the slider 6-1-3 to perform axial reciprocating motion, causing the scraper 6-3 to scrape material. The reciprocating screw 6-1-2 and the slider 6-1-3 are existing technologies and will not be described in detail here.

[0039] In this embodiment, the telescopic part 6-2 includes two second electric push rods 6-2-1. The second electric push rods 6-2-1 are fixedly connected to the lower end face of the slider 6-1-3. The telescopic ends of the second electric push rods 6-2-1 are fixedly connected to the scraper 6-3. The scraping teeth of the scraper 6-3 are made of flexible material to avoid damaging the seeds. The second electric push rods 6-2-1 can move through the slot 5-1, and the length of the slot 5-1 matches the width of the filter basket 3. The length of the threaded groove of the reciprocating screw 6-1-2 also matches the width of the filter basket 3, thereby ensuring that the scraper 6-3 can scrape the seeds in the filter basket 3 completely.

[0040] In this embodiment, the guide rod 6-1-4 is fixedly connected to the inner wall of the housing 1 at one end on the same side as the second motor 6-1-1, and the guide rod 6-1-4 away from the second motor 6-1-1 is fixedly connected to the crossbar 6-1-5 via a connecting rod. The reciprocating screw 6-1-2 is rotatably connected to the connecting rod away from the second motor 6-1-1, and the connecting rod is fixedly connected to the crossbar 6-1-5. Both ends of the crossbar 6-1-5 are fixedly connected to the inner wall of the housing 1. The crossbar 6-1-5 provides support for the reciprocating screw 6-1-2, the slider 6-1-3, the second electric push rod 6-2-1, and the scraper 6-3. It should be noted that, in the initial state, the installation position of the crossbar 6-1-5 and the length of the second electric push rod 6-2-1 should ensure that the scraper 6-3 does not interfere with the lifting and lowering of the movable platform 5.

[0041] like Figure 7As shown, a seed-holding basket 3-1 is provided inside the filter basket 3. The seed-holding basket 3-1 has a filter screen structure, and the removable clip of the seed-holding basket 3-1 is placed inside the filter basket 3. In this embodiment, the size of the filter basket 3 is smaller than the internal space of the seed soaking tank 2, with sufficient gaps to allow the filter basket 3 to move within the seed soaking tank 2. The size of the seed-holding basket 3-1 matches the inner wall of the filter basket 3, and the internal space of the seed-holding basket 3-1 matches the range of motion of the scraper rake 6-3. During operation, the seed-holding basket 3-1 is used to hold seeds. The seed-holding basket 3-1 is placed inside the filter basket 3 for seed soaking. After the draining process, the seed-holding basket 3-1 can be directly removed.

[0042] The operation process of this utility model is as follows:

[0043] First, fill the soaking tank 2 with water using the inlet valve 1-2, open the tank door 1-1, and place the seed basket 3-1 containing the seeds into the filter basket 3. Use the first electric push rod 7 to lower the filter basket 3 into the soaking tank 2 for soaking, ensuring that there is sufficient space between the filter basket 3 and the inner wall of the soaking tank 2. Use the thermometer 1-4 to observe the water temperature in the soaking tank 2. If the temperature drops, drain the low-temperature water through the outlet valve 1-3 and inject high-temperature water through the inlet valve 1-2 to change the water.

[0044] When it is necessary to turn the material or when seeds are piled up, the first motor 4-1 is started. The first motor 4-1 drives the fixed rod 4-5 and the limiting post 4-6 to rotate. The limiting post 4-6, through the sliding groove 4-7, drives the guide rod 4-2 to shake horizontally, thereby causing the entire filter basket 3 to shake. Under the shaking of the filter basket 3, the water in the soaking tank 2 fluctuates, impacting the seeds and causing them to scatter. After shaking is complete, the first motor 4-1 is stopped, and the second electric push rod 6-2-1 is started so that the scraper 6-3 contacts the seeds. After the scraper 6-3 contacts the seeds, the extension of the second electric push rod 6-2-1 stops, and the second motor 6-1-1 is started. The reciprocating screw 6-1-2 rotates, driving the slider 6-1-3 and the scraper 6-3 to perform linear reciprocating motion, thereby scraping the material. After scraping is complete, the second motor 6-1-1 is turned off, and the slider 6-1-3 and the second electric push rod 6-2-1 are reset. It should be noted that either the scraping assembly 6 or the shaking mechanism 4 can be used, and there is no restriction on the order in which they operate.

[0045] After soaking, when the seeds need to be drained, use the first electric push rod 7 to raise the filter basket 3 so that it is detached from the soaking tank 2 for draining. To improve the draining effect, the first motor 4-1 can be used to shake it again or the scraper assembly 6 can be used to scrape the material to assist in draining. After draining, open the tank door 1-1 and take out the seed basket 3-1.

[0046] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
