Description

Technical Field

[0001] The invention relates to the technical field of crop planting, and in particular to a processing device and a processing method for increasing rice seed yield. Background Art

[0002] Rice seeds are a type of agricultural product seeds. Before planting rice, it is necessary to raise rice seeds in advance. Through cultivation and germination treatment, seeds with a higher germination rate can be pre-screened, and germination treatment can promote rapid germination of seeds and improve the overall germination rate. This can ensure that more seeds become healthy seedlings and increase yields. After cultivation and germination treatment, seeds can germinate and grow faster after sowing, shortening the growth cycle and entering the heading and maturity stages earlier. Cultivation and germination treatment help activate the metabolic activity of seeds, enhance the physiological functions of the seeds themselves, and better adapt and resist when facing adversity (such as low temperature, drought, etc.), thereby improving the survival rate and yield of seeds.

[0003] Patent No. 201710963899.0 discloses a rice seed processing method for improving the germination rate of rice. The method comprises the following steps: placing sterile seeds in a soaking solution at a temperature of 13 to 17°C for 5 to 8 days, and then placing the seeds in a germination agent at a temperature of 25 to 32°C for germination for 15 to 25 hours until the seeds are broken and white. The soaking solution comprises hydrogen peroxide at a concentration of 2 to 15% and potassium nitrate at a concentration of 0.01 to 0.07%, and the germination agent comprises graphene oxide at a mass concentration of 0.001 to 0.01%. A bird repellent is added to the germinated seeds. After sowing and growing for 3 to 7 days at a temperature of 20 to 25°C, the temperature is lowered to 15 to 20°C, and a growth inhibitor at a concentration of 0.1 to 1.5% is sprayed and cultured for 5 to 10 days. However, the processing method is inefficient and is not suitable for large-scale processing.

[0004] The existing rice seed processing is not convenient for rapid and efficient rice seed processing. The rice seeds need to be transported and touched many times during soaking, germination and spraying, which can easily cause damage to the seed surface and increase the time cost of the processing steps.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention can store rice seeds conveniently by arranging a storage mechanism. The lifting mechanism can drive the storage mechanism to rise or fall to move the rice seeds to the water replenishing mechanism or the germination mechanism. When the storage mechanism drives the rice seeds to move to the inside of the water replenishing mechanism, clean water is automatically injected into the water replenishing mechanism to soak the rice seeds so that the rice seeds can absorb water. When the storage mechanism drives the rice seeds into the germination mechanism, the germination mechanism first germinates the rice seeds, and then sprays the pesticide after germination to improve the survival rate of the rice seeds. Through continuous soaking, germination and spraying, the processing efficiency of the rice seeds can be greatly improved.

[0026] 2. The present invention can automatically inject water and drain water by arranging a water replenishment mechanism. When the lifting seat moves to the bottom, the bottom of the lifting seat presses the waterproof press switch once, and fits on the top of the sealing seat and the sealing gasket to seal the drainage hole. The waterproof press switch transmits a start signal to the controller. The controller controls the solenoid valve to open once, and the opening time of the solenoid valve is set in advance by the controller. The external water source is injected into the bucket through the solenoid valve to soak the rice seeds. When the soaking is completed and drainage is required, the lifting seat moves upward, and the sewage inside the bucket enters the water outlet cover through the drainage hole, and enters the sewer pipe through the sewage pipe of the water outlet cover, so as to realize efficient soaking of the rice seeds.

[0027] 3. The present invention can prevent rice seeds from being damaged by multiple transports by providing a storage mechanism. The rice seeds are placed in a mesh frame, which is installed on the inner wall of a limiting member. A support frame on the limiting member fixes the mesh frame to prevent the rice seeds from spilling out.

[0028] 4. The present invention can germinate and spray rice seeds by arranging a germination mechanism. When germinating, water is filled into the liquid tank, and the temperature and humidity sensor detects the temperature and humidity inside the cover body. The detection signal is transmitted to the controller. The controller controls the operation of the electric heating element and the liquid pump according to the detection signal. The electric heating element heats the cover body to raise the temperature inside the cover body to a temperature suitable for germination of rice seeds. The liquid pump draws water from the liquid tank and sprays it on the inside of the cover body through a spray plate and an atomizing nozzle to increase the air humidity inside the cover body, so that the rice seeds germinate under suitable temperature and humidity. When spraying is required, liquid medicine is added to the inside of the liquid tank, the liquid medicine inside the liquid tank is drawn from the liquid tank, and the liquid medicine is evenly sprayed on the rice seeds inside the mesh frame through the spray plate and the atomizing nozzle to improve the survival rate of the rice seeds.

[0043] By setting up the water replenishment mechanism 1, water can be automatically injected and drained. When the lifting seat 201 moves to the bottom, the bottom of the lifting seat 201 presses the waterproof press switch 106 once, and fits on the top of the sealing seat 101 and the sealing gasket 102 to block the drainage hole 109.

[0045] By providing the storage mechanism 2, the rice seeds can be prevented from being damaged by multiple transportations. The rice seeds are placed in the mesh frame 204, which is mounted on the inner wall of the limiting member 202. The support frame 203 on the limiting member 202 fixes the mesh frame 204 to prevent the rice seeds from spilling out. When the rice seeds need to be taken out, the support frame 203 is rotated to release the limit on the mesh frame 204, and the mesh frame 204 is taken out from the inside of the limiting member 202. After pouring out the processed rice seeds, the lifting seat 201 moves up and down through the sliding rod 205, and the sliding rod 205 slides inside the sealing sleeve 105.

[0051] Example 2

[0052] A method for increasing rice seed yield comprises the following steps:

[0053] 1) First, the rice seeds that need to be treated to increase yield are placed in the storage mechanism 2. The lifting mechanism 3 drives the storage mechanism 2 to move vertically. When the storage mechanism 2 moves to the bottom of the inner cavity of the water replenishment mechanism 1, the external clean water is automatically injected into the water replenishment mechanism 1. When the clean water completely soaks the rice seeds, the water injection is stopped.

[0054] 2) The soaking time is 8-10 hours. When the water needs to be changed, the storage mechanism 2 is reset, and the sewage inside the water replenishment mechanism 1 is automatically discharged. After the sewage is discharged, the soaking is circulated and the soaking is stopped when the rice seeds are saturated with water.

[0055] 3) The rice seeds after absorbing water are moved to the top of the water replenishing mechanism 1 by the storage mechanism 2 to drain the water from the rice seeds.

[0056] 4) After the water of the rice seeds is drained, the lifting mechanism 3 drives the storage mechanism 2 to move into the germination mechanism 4, so that the rice seeds move into the inner cavity of the germination mechanism 4.

[0057] 5) The germination mechanism 4 controls the temperature and humidity inside the mechanism to germinate the rice seeds, and stops germination when the rice seeds turn white;

[0058] The temperature for germinating rice seeds is 25-30 degrees Celsius. Within this temperature range, the germination speed of seeds and the growth of seedlings are both fast. Temperatures above 30 degrees Celsius will cause seed dormancy or damage, and temperatures below 25 degrees Celsius will slow down the germination speed.

[0059] When rice seeds are germinated, the relative humidity should be 70-85% RH. Too high humidity will cause the seeds to rot and mold, while too low humidity will hinder the seeds from absorbing water and germination.

[0060] 6) Pour the insecticide and fungicide into the germination mechanism 4 respectively, and the germination mechanism 4 sprays the insecticide and fungicide evenly on the surface of the germinated rice seeds, wherein the insecticide is a 60% imidacloprid suspension and the fungicide is trifloxystrobin.

[0061] Mix the seeds with 60% imidacloprid suspension seed dressing agent and evenly coat the surface of the seeds. This can effectively prevent the damage of various pests such as grubs, aphids, thrips, and planthoppers. The effective period can reach 80 to 120 days.

[0062] Fluopicolide is a succinate dehydrogenase (SDH) inhibitor, which mainly acts on the electron transfer complex II of the respiratory chain to block energy metabolism. When fluopicolide is used as a seed treatment agent, the treated seeds can absorb fluopicolide during germination and transmit it to other parts of the plant body through the xylem, thereby protecting the crop.

[0063] As a seed treatment fungicide, fluopicolide can prevent and control seed-borne and soil-borne basidiomycete and ascomycete diseases, such as potato black mole, wheat sheath blight, rice sheath blight, rapeseed sclerotinia, wheat loose smut, wheat bunt, corn leaf spot, etc. It can also be combined with prothioconazole, metalaxyl, clothianidin, trifloxystrobin, etc., which can not only prevent and control diseases and pests, but also delay the generation and development of resistance.

[0064] 7) After the pest control and sterilization are completed, take out the rice seeds and dry them in the shade to remove excess moisture on the surface of the seeds to prevent the seeds from deteriorating and mildewing.

[0065] 8) After the rice seeds are dried in the shade, they are placed on the seedbed and covered with gauze to strengthen the seedlings. Covering with gauze helps maintain suitable humidity and temperature and promotes the growth of seedlings.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
