Description

Technical Field

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

[0002] Before soaking rice seeds, sun-drying them for about two days on a sunny day can enhance seed coat permeability, increase enzyme activity, and improve germination rate and vigor; reduce the concentration of germination inhibitors within the seeds, promoting earlier germination; ensure uniform seed drying, eliminate differences in moisture content, and guarantee even water absorption and uniform germination after soaking; it also has a certain bactericidal effect. Then, seed selection can be carried out using a grain winnowing machine or a grain suction device used for loading, removing shriveled, diseased, and other impurities, leaving plump, high-density seeds.

[0003] Next, soak the seeds in clean water (or add chemicals and soak the seeds in the solution for a certain period of time to achieve sterilization and disease prevention). Soaking requires warm water at about 30℃. After soaking for a period of time, put them in a mesh bag, or first put them in a bag for soaking, and then transfer them to a constant temperature incubator for warming and germination. The soaking and warming process can be repeated 2-3 times. If possible, you can also spray clean water to keep the bag moist.

[0004] In the current operation, seeds are soaked in a water-filled container, and germination is carried out using a heat-insulating device. However, this operation method is still not convenient enough. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a rice seed soaking and germination device, which aims to solve the above technical problems.

[0006] The present invention adopts the following technical solution:

[0007] The rice seed soaking and germination device includes a main frame, side frames, and a top cover. A conical barrel with a wider opening at the top and a narrower opening at the bottom is installed on the main frame. A mesh frame is placed inside the conical barrel. A heating coil is located near the bottom of the conical barrel. A heating component is also located in the upper part of the conical barrel. A groove plate is located on the inner side of the top of the conical barrel. The top cover is placed inside the groove plate. A water spray pipe is located on the inner side of the groove plate. A water nozzle is located on the inner side of the water spray pipe. A heating water tank is installed on the side frame. The heating water tank is connected to the bottom of the conical barrel through a pump pipe. A circulation pipe is also connected between the bottom of the conical barrel and the water spray pipe. A first water pump is installed on the pump pipe, and a second water pump is installed on the circulation pipe.

[0008] Furthermore, the lower part of the cone-shaped barrel has a water temperature sensor, the bottom of the top cover has an ambient temperature sensor, the top of the top cover has a temperature display screen, and the side wall of the main frame has a control box.

[0009] Furthermore, a short pipe is connected to the bottom of the cone, and a three-way valve is connected to the short pipe. One port of the three-way valve is connected to the pump pipe, and the other port is connected to the circulation pipe.

[0010] Furthermore, the circulation pipe is also connected to a drain pipe, which has a drain valve.

[0011] Furthermore, the space frame includes a square tube frame located around the outer perimeter, with a grid inside the tube frame, and beveled feet welded to the four corners of the tube frame.

[0012] Furthermore, the top of the heating water tank has a flip-top cover with a handle.

[0013] Furthermore, the bottom of the trough plate has drainage holes.

[0014] The beneficial effects of this invention are as follows: A mesh bag containing rice seeds is placed flat on a mesh frame. After heating the water in the conical bucket and the heated water tank, water from the heated water tank is pumped to the conical bucket through a pump pipe, submerging the seeds for soaking. Then, some of the water in the conical bucket recedes back into the water tank. The temperature of the upper part of the conical bucket is controlled to promote germination. During germination, the seeds are sprayed with water through a spray pipe to maintain humidity, which is conducive to germination. This process can be repeated 2 or 3 times. After the final germination is completed, the seeds are removed. Therefore, this device can integrate soaking, water spraying, and germination, without requiring replacement of the device, and allows for repeated soaking and germination operations, making it simple to operate.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] like Figures 1-3As shown, the rice seed soaking and germination device provided by the embodiment includes a main frame 1, a side frame 2 and a top cover 3. The main frame 1 is provided with a tapered barrel 4 with a large opening at the top and a small opening at the bottom. A net frame 5 is placed in the tapered barrel 4. A heating coil 40 is arranged near the bottom of the tapered barrel 4. A heating assembly 44 is arranged at the upper part of the tapered barrel 4. A groove plate 41 is arranged at the inner side of the top of the tapered barrel 4. The top cover 3 is placed in the groove plate 41. A water spraying pipe 42 is arranged at the inner side of the groove plate 41. A water nozzle 43 is arranged at the inner side of the water spraying pipe 42. The side frame 2 is provided with a heating water tank 6. The heating water tank 6 is connected to the bottom of the tapered barrel 4 through a pump pipe 71. A circulating pipe 72 is further connected between the bottom of the tapered barrel 4 and the water spraying pipe 42. A first water pump 73 is arranged on the pump pipe 71. A second water pump 74 is arranged on the circulating pipe 72.

[0021] In the structure, the tapered barrel has a large opening at the top and a small opening at the bottom, and can accommodate net frames of different sizes. As a specific structure of the net frame 5, the net frame 5 includes a square tube frame 51 arranged at the outer periphery. The tube frame 51 is provided with a grid 52. Inclined feet 53 are welded at the four corners of the tube frame 51. The inclination of the inclined feet 53 matches the angle of the edge of the tapered barrel, so that the net frame can be placed more stably and will not be overturned after the rice seeds are placed. Moreover, the grid is relatively dense and can uniformly support the net bag.

[0022] The tapered barrel has the function of heating water. The water tank on one side also has the function of heating water. The two are connected through a pump pipe. Before soaking the seeds, the seeds are first placed in a net bag and then flattened on the net frame. If the water temperature is not enough, the water in the tapered barrel and the water tank can be heated to about 30 degrees. A water temperature sensor is arranged at the lower part of the tapered barrel to monitor and control the water temperature. After heating, the first water pump is started. The pump pipe pumps the warm water in the water tank into the tapered barrel. The water level in the tapered barrel rises until the net bag is submerged. After maintaining the warm water temperature for a period of time, the water in the tapered barrel flows back according to the high and low water level difference or is pumped into the water tank through the first water pump. Here, only part of the water needs to be returned so that the water level is lower than the net bag.

[0023] The top cover can be covered in advance. The bottom of the top cover is located in the groove plate, which has a certain sealing and heat preservation effect, and is also more stable to place. In order to avoid water accumulation in the groove plate 41, the bottom of the groove plate 41 is provided with a water leakage hole 44. The top cover is a transparent plastic cover. The water droplets accumulated on the inner wall flow into the groove plate and can be discharged through the water leakage hole 44. During germination, the ambient temperature around the net bag needs to be ensured. In the embodiment, an ambient temperature sensor 31 is arranged at the bottom of the top cover 3. A temperature display screen 32 is arranged at the top of the top cover 3. A control box 8 is arranged on the side wall of the main frame 1. Through the control box, the water temperature, the ambient temperature and the soaking and germination time can be set. The control box is connected with various sensors and heating components. In the embodiment, during germination, if the ambient temperature is not enough, the heating assembly can be controlled to work to heat the ambient temperature, so that the environment is maintained at the target germination temperature. The germination temperature is generally between 25-35℃.

[0024] During the germination process, water can be sprayed. Specifically, the second water pump 74 is opened, water is injected into the spray pipe through the circulating pipe, and the water is sprayed through the water nozzle to maintain the moisture of the seeds.

[0025] In addition, as a preferred structure, the bottom of the cone barrel 4 is also connected with a short pipe 75, the short pipe 75 is connected with a three-way valve 76, one port of the three-way valve 76 is connected to the pump pipe 71, and the other port is connected to the circulating pipe 72. The three-way valve 76 is connected to the control box, and the opening and closing of the two ports can be automatically controlled. One of the ports can be opened, or both ports can be closed. When the pump pipe and the short pipe are connected, the water in the water tank can be pumped into the cone barrel, and at the same time, the water in the cone barrel can be returned to the water tank to reduce the water level. When the circulating pipe and the short pipe are connected, the water spraying operation can be performed. On the other hand, the circulating pipe 72 is also connected with a drain pipe 77, and the drain pipe 77 is provided with a drain valve 78. The water in the cone barrel and the water tank can be drained through the drain pipe to clean and replace the water. The top of the heating water tank 6 is provided with a flip cover 61, and the flip cover 61 is provided with a handle 62. The flip cover can be opened through the handle.

[0026] The seed soaking and germination operations described above can be repeated.

[0027] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
