Description

Technical Field

[0001] This utility model relates to the technical field of rice storage equipment, and in particular to a rice storage device for preventing insects and decay. Background Technology

[0002] Rice is an important food that can satisfy human hunger. During the storage process, in order to ensure that the quality of rice is maintained in a good state, it is necessary to observe and test the storage conditions in a timely manner. In order to prevent the stored rice from getting moldy, it is necessary to ventilate the stored rice. In areas with high air humidity, it is necessary to dehumidify the rice storage environment and use rice storage insect-proof and anti-corrosion devices.

[0003] A search revealed Chinese patent CN216509923U, which discloses an insect-proof and anti-corrosion device for rice storage. The device includes a body with two fixed pipes connected to its outer surface. Fans are fixedly connected to the inner surfaces of both pipes. Two support rods are fixedly connected to the top of the body, and a top plate is fixedly connected between the top ends of the support rods. A motor is fixedly connected to the bottom of the top plate, and a shaft is fixedly connected to the output end of the motor. The outer surface of the shaft is rotatably connected to the inner wall of the body. This insect-proof and anti-corrosion device for rice storage increases the airflow velocity above the body by activating the fans, quickly replacing the air inside the body. Activating the motor drives rotating blades to stir the rice inside the body, causing humid air between the rice grains to be quickly expelled along with the replaced air, thus maintaining the dryness inside the body and preventing mold growth on the rice.

[0004] This patent only allows for mechanical ventilation of rice, but it cannot provide different protective measures for the rice based on weather conditions. This can easily lead to a waste of electricity due to continuous mechanical operation, which is not conducive to saving energy. At the same time, it cannot effectively prevent insects and dust during the ventilation process, which can easily allow insects and dust to enter the rice in the rice warehouse through the ventilation structure, thus hindering the improvement of rice quality. Utility Model Content

[0005] In view of the technical problems in existing patents, which only ventilate rice through mechanical operation and cannot protect rice according to different weather conditions, the continuous operation of the machinery easily leads to a large waste of electricity, which is not conducive to saving energy.

[0012] Furthermore, a support frame is fixedly installed below the rice bin.

[0013] Furthermore, a discharge pipe is fixedly installed below the rice bin, passing through the side wall of the support.

[0014] Furthermore, the outlet pipe is equipped with a sealing cap.

[0025] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0026] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a rice storage device for preventing insects and decay.

[0027] The specific technical solution includes a rice storage bin 1 and an adjustable ventilation assembly 2;

[0028] like Figure 1-4As shown, the adjustable ventilation assembly 2 is installed above the rice bin 1. The adjustable ventilation assembly 2 is used to adjust the ventilation inside the rice bin 1. The adjustable ventilation assembly 2 includes a filter cylinder 201 inserted through the center of the rice bin 1 and two ventilation structures symmetrically installed above the rice bin 1. The filter cylinder 201 can separate and store the rice inside the rice bin 1. The ventilation structure includes a top box 202 located above the filter cylinder 201. The top box 202 can support the ventilation fan 203. The ventilation fan 203 and a baffle plate 204 are fixedly installed inside the top box 202. The ventilation fan 203 can... The airflow inside the top box 202 is driven by the air guide plate 204, which guides the airflow inside the top box 202. The ventilation fan 203 is located above the air guide plate 204. The top and bottom surfaces of the top box 202 are respectively provided with an air inlet 3 and an air outlet 4 that communicates with the filter cartridge 201. The air inlet 3 can facilitate the intake of air into the top box 202, and the air outlet 4 can facilitate the air from the top box 202 to be ejected into the filter cartridge 201. The side wall of the top box 202 is fixedly equipped with a gear 205 that is fixedly connected to the rice bin 1. The gear 205 can easily drive the top boxes 202 on both sides to move together.

[0029] In hot weather, by activating ventilation fans 203, one fan 203 draws air from outside the top box 202 into the top box 202 through the air inlet 3. The air inside the top box 202 is then more fully blown into the air outlet 4 via the guide plate 204, and finally into the filter cartridge 201. Simultaneously, another ventilation fan 203 draws hot air from inside the filter cartridge 201 into another top box 202 through the air outlet 4. The hot air inside the other top box 202 is then exhausted through the air inlet 3. The two ventilation fans 203 work together to rapidly circulate the air inside the filter cartridge 201. Rapid air circulation within the filter cartridge 201 ensures adequate ventilation for the rice inside the rice bin 1, preventing it from becoming suffocated due to high temperature. When a large air intake is not required at a specific temperature, the rotation of one gear 205 drives the connected gear 205 to rotate. The two gears 205 rotate in opposite directions, causing the two top boxes 202 to rotate. This allows the two top boxes 202 to open from the top of the filter cartridge 201, enabling natural ventilation inside the filter cartridge 201. This ventilation facilitates airflow for the rice inside the rice bin 1.

[0030] like Figure 1-3 As shown, a cloth bag 5 is fixedly installed inside the filter cartridge 201, which can conveniently filter dust and insects.

[0031] When the air inside the top box 202 enters the filter cartridge 201 through the air outlet 4, the air entering the filter cartridge 201 through the air outlet 4 is first filtered by the cloth bag 5. The air filtered by the cloth bag 5 then enters the rice inside the rice bin 1 through the filter cartridge 201. The cloth bag 5 can easily filter and intercept insects and dust.

[0032] like Figure 1 and Figure 3-4 As shown, a power assembly 6 is installed on one side of the rice bin 1. The power assembly 6 is used to drive the gear 205 to rotate. The power assembly 6 includes a screw 601 fixedly connected to a gear 205 and a connecting rod 602 located on the rice bin 1. The screw 601 can be connected to a gear 205, and the connecting rod 602 can support the sleeve 603. The sleeve 603, which is fixedly connected to the connecting rod 602, is sleeved on the outside of the screw 601. The sleeve 603 can support the ball 604. The ball 604, which is threadedly connected to the screw 601, is fixedly installed inside the sleeve 603. The ball 604 can be easily connected to the screw 601. A telescopic rod 605, which is fixedly connected to the rice bin 1, is fixedly installed below the connecting rod 602. The telescopic rod 605 can drive the connecting rod 602 to rise and fall.

[0033] The connecting rod 602 is limited by the telescopic rod 605 and cannot rotate. The connecting rod 602 can limit the sleeve 603, and the sleeve 603 can limit the ball 604. The ball 604 cannot rotate. By activating the telescopic rod 605, the telescopic rod 605 retracts, causing the connecting rod 602 to descend. The connecting rod 602 causes the sleeve 603 to descend, and the sleeve 603 causes the ball 604 to descend. The ball 604 exerts downward pressure on the thread of the screw 601. The screw 601 is limited by the gear 205, and the screw 601 can only rotate but cannot descend. Therefore, after the ball 604 exerts downward pressure on the thread of the screw 601, the screw 601 can rotate. The rotation of the screw 601 can drive the gear 205 to rotate, and the rotation of the gear 205 can drive the top box 202 to open.

[0034] like Figure 1 and Figure 4 As shown, a bracket 7 is fixedly installed below the rice bin 1, which can support the rice bin 1.

[0035] like Figure 1 As shown, a discharge pipe 8 is fixedly installed below the rice bin 1 and passes through the side wall of the bracket 7. The discharge pipe 8 can easily remove rice from the inside of the rice bin 1.

[0036] like Figure 1 As shown, the port of the discharge pipe 8 is equipped with a sealing cap 9, which can seal the discharge pipe 8.
