Description

Technical Field

[0001] The utility model relates to the technical field of rice planting, in particular to a germination accelerating device for rice planting. Background Art

[0002] Rice germination refers to the process of allowing rice seeds to germinate under certain temperature, humidity and oxygen conditions before sowing. Rice germination is a key step that aims to improve the germination rate and germination potential of rice, shorten the seedling period, increase the seedling rate, and thus promote the growth and yield of rice. There are many ways to germinate rice, including the double-layer sack germination method, the warm water rapid germination method, the multiple-lifting and multiple-dropping seed soaking germination method, the warm water chest-breaking method in a pot, and the direct seeding method.

[0003] Among them, the warm water rapid germination method is to choose a place that is sheltered from the wind and warm, lay a layer of straw 24 to 30 cm thick, and place the prepared water tank on it; pour warm water of about 40°C into the tank, put the drained seeds into the warm water, stir while pouring, so that they are heated evenly, and control the water temperature at about 38°C. Seal the mouth of the tank with a film and pile up straw to keep it warm. After 5 to 6 hours, take out the seeds, drain them slightly, cover them with straw and let them be exposed to the warm water for 18 to 19 hours. Repeat the soaking and exposure of seeds many times until the expected germination rate is reached.

[0004] In the prior art, the warm water rapid germination method is to directly put the drained seeds into warm water, stirring them while pouring to make them evenly heated. However, this method directly adds the seeds into the device without selecting the seeds. In this way, good and bad seeds are soaked and germinated together without grading, which will transmit some diseases to good seeds, affecting the germination rate of the seeds, and the seeds cannot achieve the expected germination rate. Summary of the invention

[0005] The utility model aims to provide a germination device for rice planting, which can make the water in the germination cylinder rotate and flow through the impact of stirring and drainage, so that the blighted grains, half-blighted grains and black powdery grains in the seeds can be fully suspended and moved to the seed selection sleeve groove under the action of the rotating centrifugal force, so that the blighted grains, half-blighted grains and black powdery grains floating in the seed selection sleeve groove can be picked up, avoiding the transmission of some diseases to good seeds, thereby achieving the seed selection effect and ensuring the germination rate of the seeds, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a germination device for rice planting, comprising a germination cylinder, a support frame is fixedly installed on the top of the germination cylinder, a speed regulating motor is fixedly installed at the middle position of the top of the support frame, the output end of the speed regulating motor passes through the support frame and is fixedly connected to a stirring assembly shaft, a fixed blocking block is fixedly installed inside the stirring assembly shaft, and a seed selection temperature control component is commonly provided inside and outside the germination cylinder and the stirring assembly shaft;

The top height of the seed selection sleeve groove is higher than the top height of the germination cylinder body.

[0008] Preferably, the seed selection and temperature control assembly further comprises a circulating water pump fixedly mounted on the outer wall of the germination cylinder, and the input end of the circulating water pump is communicated with the bottom end surface of the seed selection sleeve groove.

[0009] Preferably, the output end of the circulating water pump is connected to a heating water tank, the output end of the heating water tank is connected to a connecting pipe, and the output end of the connecting pipe is connected to a waterway.

[0010] Preferably, the water channel is opened at the bottom end of the stirring assembly shaft, and the stirring assembly shaft is rotatably connected to the connecting pipe.

[0011] Preferably, the output end of the water channel is connected to a first convection tube and a second convection tube, the first convection tube and the second convection tube are both fixed on the wall of the stirring assembly shaft, and the opposite surfaces of the first convection tube and the second convection tube are correspondingly provided with water spray holes.

[0012] Preferably, the germination cylinder and the stirring assembly shaft are provided with an oxygen supply and seed rubbing component inside and outside, and the oxygen supply and seed rubbing component includes an air pump fixedly mounted on the outer wall of the top end of the germination cylinder, the output end of the air pump is connected to a connecting air pipe, and the output end of the connecting air pipe is connected to a connecting ring, and the connecting ring is rotatably connected to the stirring assembly shaft.

[0013] Preferably, an air passage is provided at the inner upper end of the stirring assembly shaft, and a connecting hole provided on the outer wall of the stirring assembly shaft is provided at the connection between the connecting ring and the stirring assembly shaft, and the connecting hole and the air passage are connected to each other.

[0014] Preferably, a first air pipe and a second air pipe are fixedly mounted on the bottom end of the outer wall of the stirring assembly shaft, the first air pipe and the second air pipe are interconnected with the airway, and air holes are correspondingly opened on the opposite surfaces of the first air pipe and the second air pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model stirs the rice seeds in the germination cylinder body through the rotation energy between the first convection tube and the second convection tube, so that the rice seeds can be evenly heated in the warm water, and the seeds are prevented from being damaged due to excessively high or low local temperature. At the same time, the discharge impact of the water flow in the first convection tube and the second convection tube can prevent the seeds from sticking to each other during the soaking process, ensuring that each seed can fully absorb water and heat, which is beneficial to the germination of the seeds. The combination of impact and stirring can reduce the bacteria and insect eggs on the surface of the seeds, reduce the risk of seed disease, and further improve the germination rate. In addition, the water in the germination cylinder body can be rotated and flowed through the impact energy of stirring and drainage, so that the blighted grains, half-blighted grains, and black powdery grains in the seeds can be fully suspended, and moved to the seed selection sleeve groove under the action of the rotating centrifugal force, so that the blighted grains, half-blighted grains, and black powdery grains floating in the seed selection sleeve groove can be picked up, so as to avoid transmitting some diseases to good seeds, thereby achieving the seed selection effect and ensuring the germination rate of the seeds.

[0017] 2. The oxygen supply and seed rubbing assembly provided in the utility model can provide sufficient oxygen for the germination of seeds. In this way, when there is sufficient oxygen, the respiration of the seeds can proceed normally and the metabolism rate is accelerated, which helps the organic matter stored inside the seeds to be effectively decomposed and utilized, and provides energy for the germination of seeds. In an environment with sufficient oxygen, the respiration of the seeds can proceed normally, and the metabolic waste generated can be effectively eliminated, which helps to reduce the breeding and reproduction of pathogens. At the same time, the air ejected through the stomata and the water flow ejected from the water spray holes can play a seed rubbing effect on the rice seeds. By rubbing the seeds, it can be ensured that the surface of the seeds is fully in contact with the warm water, so that the seeds absorb water more evenly. This helps to activate the biologically active substances in the seeds and prepare for the water absorption and expansion before germination. During the seed rubbing process, the epidermis of the seeds may be separated from some impurities such as dust and soil. The removal of these impurities can reduce the potential interference with seed germination. BRIEF DESCRIPTION OF THE DRAWINGS
