Description

Technical Field

[0001] This utility model belongs to the field of rice storage hopper technology, specifically a rice storage hopper with a ventilation structure. Background Technology

[0002] With the improvement of modern people's living standards, higher requirements have been put forward for the storage quality and storage environment of grain. As one of the staple foods in the family, the storage method of rice is directly related to the shelf life and eating quality of rice. However, in a humid and hot environment, rice is prone to moisture and deterioration, mold growth or pests, affecting its freshness and even causing food waste.

[0003] Traditional rice storage containers are mostly sealed, which can isolate air and moisture for a short time, but long-term sealing will lead to a hot and humid environment inside the container, which can easily cause the rice grains to mold or become stale. Especially in humid environments in the south or seasonally humid areas, the ventilation of rice storage containers is particularly important. Therefore, we have proposed a rice storage container with a ventilation structure. Utility Model Content

[0004] To address the issue that most traditional rice storage containers are primarily sealed, which, while isolating air and moisture for short periods, leads to a humid and hot environment inside the container over extended periods, easily causing mold or staleness in the rice, especially in humid southern environments or seasonally damp areas where ventilation is crucial, this invention provides the following technical solution: a rice storage hopper with a ventilation structure, including a ventilation mechanism.

[0005] The ventilation mechanism includes an inner rice bin, an outer shell surrounding the inner rice bin, and a ventilated interlayer between the outer shell and the inner rice bin. The outer shell has a feed inlet with a sealing cap and ventilation holes. The inner rice bin has a rotating adjusting disc with protrusions. The outer shell has a recessed portion that matches the protrusions. The outer shell has an adjustment port with a slidable adjusting handle connected to the rotating adjusting disc. The bottom of the outer shell has a discharge port.

[0006] It also includes a discharge mechanism, which includes a support plate disposed at the bottom of the outer shell. The bottom of the outer shell is provided with a sliding groove, and a baffle is slidably disposed on the sliding groove. The baffle is disposed at the bottom of the discharge port. One end of the baffle is connected to the support plate by a spring, and the other end of the baffle is connected to a pull ring.

[0007] Preferably, the inner rice bin has multiple through holes that are evenly distributed and covered with metal mesh or plastic mesh. The diameter of the through holes is 0.5-1 mm, which ensures air circulation while preventing pests and impurities from entering.

[0008] Preferably, the rotating adjustment disk is provided with a ventilation adjustment hole group, which includes large holes, medium holes and small holes arranged in sequence. The number of ventilation adjustment holes matches the number of ventilation holes. The large holes are the same size as the ventilation holes. Users can rotate the adjustment disk to align the holes of different sizes with the ventilation holes, thereby adjusting the ventilation volume to meet the needs of different storage environments.

[0009] Preferably, the support plate has an opening and a measuring cup is provided on the support plate to facilitate user control of the amount of rice dispensed.

[0010] Preferably, the adjustment port is provided with a gear scale to indicate the position of the adjustment handle and the current ventilation volume, helping the user to control the opening of the ventilation hole more intuitively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During operation, open the sealing cover and add rice into the inner rice hopper through the feed inlet. After adding rice, close the sealing cover to ensure airtightness. The adjusting disc can be rotated using the adjusting handle inside the adjusting port, depending on the ambient humidity and storage requirements. Rotating the adjusting disc aligns different sized holes with the ventilation holes on the outer shell, controlling the airflow inside the rice hopper. If ventilation is not needed, rotate the adjusting disc to the hole-free position to close the ventilation holes and maintain a tight seal. To remove rice, pull the ring. The ring slides through a groove to open the discharge port, allowing the rice grains to flow out under gravity. The baffle is connected to the support plate by a spring. Releasing the ring automatically resets the spring, closing the discharge port and preventing further rice outflow. This allows air to circulate inside and outside the rice hopper, effectively regulating internal humidity, preventing the rice from becoming damp and moldy, and ensuring airtightness.

[0029] Working principle: During operation, open the sealing cover and add rice into the inner rice hopper 1 through the feed inlet 5. After adding rice, close the sealing cover to ensure airtightness. The adjusting disc 7 can be rotated via the adjusting handle 10 inside the adjusting port 9, depending on the ambient humidity and storage requirements. Rotating the adjusting disc 7 aligns different sized holes with the ventilation holes 6 on the outer shell 2. By adjusting the size of these holes, the airflow inside the rice storage hopper can be controlled. If ventilation is not required, the adjusting disc 7 can be rotated to... In the non-perforated position, the ventilation hole 6 is closed to maintain a tight seal. When taking out rice, pull the pull ring 16. The pull ring 16 controls the baffle 14 to slide through the slide groove, opening the discharge port 12. The rice grains flow out through the discharge port 12 under the action of gravity. The baffle 14 is connected to the support plate 13 under the action of the spring 15. After releasing the pull ring 16, the spring 15 automatically resets, and the baffle 14 closes the discharge port 12 to prevent the rice grains from continuing to flow out. This allows air to circulate inside and outside the rice storage hopper, effectively regulating the internal humidity, preventing the rice from getting damp and moldy, and ensuring airtightness.
