Description

Technical Field

[0001] The utility model relates to the technical field of seed germination rate testing, in particular to a wheat seed germination rate testing device. Background Technique

[0002] The planting amount of wheat is large. During the cultivation process of wheat seeds, measuring the germination rate of wheat seeds is one of the important criteria for measuring the quality of seeds. The germination rate refers to the percentage of the number of germinated test seeds in the total number of test seeds. In agricultural production, seed germination rate detection is an indispensable technical link. Therefore, before the seeds are put into use, corresponding testing devices are needed to test the germination rate of the seeds.

[0003] At present, when testing the germination of wheat seeds, first soak a certain number of wheat seeds, and then wrap them with a cloth bag for heat preservation and germination promotion. However, the germination promotion environment is unstable, which affects the effect of wheat seed germination promotion, and even affects the germination rate of wheat seeds. Moreover, after germination promotion, manually select the ungerminated seeds and calculate the germination rate of wheat seeds. However, the manual selection process is time-consuming and laborious, which not only affects the convenience and efficiency of the wheat seed germination rate test, but also increases the labor intensity of the staff.

[0028] Please refer to Figures 1-4

[0029] Figures 1-4 Please refer to​, a water pump 6 is fixedly installed inside the water tank 3. The drainage end of the water pump 6 is fixedly installed with an extension pipe 7. The other end of the extension pipe 7 is fixedly installed with a spraying pipe 8. The bottom of the spraying pipe 8 is fixedly installed with a nozzle 9. The water pump 6 extracts water and sprays it on the seeds through the nozzle 9 to ensure the moisture of the seeds. The top of the water tank 3 is fixedly installed with a water inlet pipe 10, and the water inlet pipe 10 extends upward to the top of the cabinet 2 to facilitate adding water to the water tank 3.

[0030] Please refer to Figures 4-8 , on both sides of the inner wall of the cabinet 2, guide rails 11 are fixedly installed. Inside the guide rails 11, guide rods 12 are slidably installed. Between the guide rods 12, a tray 13 is fixedly installed. The extension pipe 7 extends upward above the tray 13. A strip-shaped opening 14 is formed in the inner bottom wall of the tray 13. The bottom of the tray 13 is fixedly installed with a collection box 15. The inner bottom wall of the collection box 15 is inclined to reduce the accumulation of water. A guiding pipe 16 is fixedly installed on the back of the collection box 15. A corrugated hose 17 is detachably installed between the guiding pipe 16 and the water tank 3. When the tray 13 is pulled out, the corrugated hose 17 deforms accordingly to adapt to the position of the tray 13.

[0031] Please refer to Figures 4-8 , a filter box 18 is arranged inside the tray 13. Leak holes are formed in the bottom of the filter box 18 to facilitate the flow of water. Limiting strips 19 are fixedly installed on the inner wall of the filter box 18. A sponge pad 20 is arranged inside the filter box 18 to intercept water. A seedling tray 21 is placed inside the filter box 18. The nozzle 9 is located above the seedling tray 21. Grooves are formed in the bottom of the seedling tray 21, and the sponge pad 20 is placed in the grooves.

[0032] Please refer to Figures 4-8 , limiting grooves 22 corresponding to the limiting strips 19 are formed on the outer surface of the seedling tray 21. The seedling tray 21 is slidably installed in the filter box 18 through the limiting grooves 22 and the limiting strips 19. Step eye holes 23 are formed on the surface of the seedling tray 21, and the step eye holes 23 are arranged in a ten-by-ten pattern. Each step eye hole 23 contains a seed, which is convenient for directly observing the germination situation and calculating the germination rate. A sponge round pad 24 is arranged inside the step eye hole 23. A water guiding cotton column 25 is fixedly installed at the bottom of the sponge round pad 24. The sponge round pad 24 and the water guiding cotton column 25 are in a T shape. The water guiding cotton column 25 presses against the inside of the sponge pad 20 to draw the water in the sponge pad 20 upward to ensure the moisture of the seeds.

[0033] Working principle: During use, the tray 13 can be pulled out from the cabinet body 2 through the guide rail 11 and the guide rod 12. Then, the seeds are placed in the ten-by-ten stepped eyelets 23. After that, the tray 13 is pushed back into the interior of the cabinet body 2. Then, the water pump 6 is used to extract the water source from the water tank 3 and spray it through the nozzle 9, so as to moisten the seeds in the stepped eyelets 23. The excess water will leak away from the filter box 18 and flow back to the water tank 3 through the strip-shaped opening 14, the collection box 15, the guiding pipe 16 and the corrugated hose 17.

[0034] By placing the wheat seeds in the ten-by-ten arranged stepped eyelets 23, each stepped eyelet 23 contains one seed, and the seed is located on the sponge round pad 24. The sponge round pad 24 can adsorb the water on the sponge pad 20 by means of the water-absorbing cotton column 25, ensuring that the seeds are in a moist state, thereby improving the germination rate of the wheat seeds. After waiting for the seeds to germinate, the tray 13 can be pulled out from the cabinet body 2. By observing the germination situation of each stepped eyelet 23 and according to the ratio of the number of germinated seeds to the total number of seeds, the germination rate of the wheat seeds can be quickly calculated.
