[0003] Existing bird feeders are poorly ventilated and moisture-proof, which can easily lead to mold and spoilage of bird food. This not only wastes food but also harms the health of birds. Therefore, to address the shortcomings of existing bird feeders, we have proposed a new ventilated, moisture-proof, and mold-proof bird feeder. Utility Model Content
[0004] The purpose of this invention is to provide a ventilated, moisture-proof, and mold-proof bird feeder to solve the problem mentioned in the background art that the existing bird feeders do not provide adequate ventilation and moisture protection, which can easily lead to mold and spoilage of bird food. This not only wastes food but also endangers the health of birds.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilated, moisture-proof, and mildew-proof bird feeder, comprising a grain storage bin, the top of which is fixedly connected to a roof via a support rod, an exhaust vent being opened through the middle of the top of the grain storage bin, a filter frame extending into the grain storage bin being installed inside the exhaust vent, an exhaust fan being installed near the top inside the filter frame, a grain outlet being opened through the front side of the grain storage bin near the bottom, and the grain outlet being inclined downwards, a tray being installed at the bottom of the grain outlet and at the front end of the grain storage bin, the tray having several ventilation holes, and a camera being installed at the front end of the grain storage bin and above the tray.
[0006] Preferably, filter screen holders are installed on both sides inside the grain storage silo. On the side of the two filter screen holders that are far apart from each other and located on the outer wall of the grain storage silo, there is an installation groove. An installation seat is slidably installed in the installation groove on both sides. An air inlet is opened above the installation groove on one side of the filter screen holder.
[0007] Preferably, the two ends of the pallet are snapped onto the two sides of the outer surface of the grain storage silo, and symmetrical grooves are provided on both sides of the bottom end of the grain storage silo, with crossbars fixedly connected inside the grooves on both sides.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model involves pinching the sliding plates on both sides of the bottom of the grain storage bin, causing the sliding plates on both sides to move the limiting plates along the crossbar towards each other, and compressing the springs, thereby moving the limiting plates into the grooves. Then, the tray is snapped into the bottom front of the grain storage bin. Next, the pinching of the sliding plates is released, causing the limiting plates to extend through to the outside of the grain storage bin under the force of the springs, and to insert into the corresponding limiting grooves on the inside of the tray, thereby fixing the tray and facilitating subsequent disassembly and cleaning. After the tray is fixed, bird food is stored inside the grain storage bin, and then the bird food falls into the tray through the feed outlet, making it convenient for birds to eat.
[0013] 2. This utility model involves sliding a mounting base containing a desiccant into the mounting groove, then turning on the exhaust fan to allow outside air to enter the grain storage bin through the air inlet. The desiccant absorbs moisture from the air, and the dried air is then exhausted through the exhaust fan from the air outlet. This ensures that the bird food inside the grain storage bin is stored in a dry and ventilated environment, preventing the bird food from becoming moldy and spoiled. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Please see Figures 1 to 4 An embodiment of this utility model provides a ventilated, moisture-proof, and mildew-proof bird feeder, comprising a grain storage bin 1. The top of the grain storage bin 1 is fixedly connected to a canopy 2 by a support rod. An exhaust hole 103 is opened through the middle of the top of the grain storage bin 1. A filter frame 7 extending into the grain storage bin 1 is installed inside the exhaust hole 103. An exhaust fan 8 is installed near the top inside the filter frame 7. A grain outlet 104 is opened through the front side of the grain storage bin 1 near the bottom, and the grain outlet 104 is inclined downward. A tray 3 is installed at the bottom of the grain outlet 104 and at the front end of the grain storage bin 1. Several ventilation holes 301 are opened on the tray 3. A camera 4 is installed at the front end of the grain storage bin 1 and above the tray 3.
[0021] The two ends of the pallet 3 are snapped onto the two sides of the outer surface of the grain storage silo 1. Symmetrical grooves 105 are provided on both sides of the bottom end of the grain storage silo 1. A crossbar 9 is fixedly connected inside the grooves 105 on both sides. A sliding plate 10 is slidably connected to the outer surface of the two crossbars 9. A spring 11 is fixedly connected between the side of the two sliding plates 10 that is close to each other and the inner wall of the groove 105. The spring 11 is wrapped around the outer surface of the crossbar 9. A limiting plate 12 is fixedly connected to the side of the two sliding plates 10 that is far away from each other. The end of the limiting plate 12 that is away from the sliding plate 10 moves through the groove 105 and extends to the outside of the grain storage silo 1. A limiting groove 302 matching the limiting plate 12 is provided on the inner side of the outer surface of the grain storage silo 1 where the pallet 3 is snapped onto. The end of the limiting plate 12 that extends through to the outside of the grain storage silo 1 is inserted into the corresponding limiting groove 302.
[0022] By pinching the sliding plates 10 on both sides of the bottom of the grain storage bin 1, the sliding plates 10 on both sides drive the limiting plates 12 to move along the crossbar 9 towards the side that is closer to each other, and compress the spring 11, so that the limiting plates 12 move and are stored inside the groove 105. Then, the tray 3 is snapped into the bottom of the front side of the grain storage bin 1. Then, the pinching of the sliding plates 10 is released, so that the limiting plates 12 extend through to the outside of the grain storage bin 1 under the action of the spring 11 and are inserted into the corresponding limiting groove 302 on the inside of the tray 3, thereby fixing the tray 3.
[0023] Filter screen seats 6 are installed on both sides inside the grain storage silo 1. On the side of the two filter screen seats 6 that are far apart from each other and located on the outer side wall of the grain storage silo 1, there is an installation groove 102. An installation seat 5 is slidably installed in the installation groove 102 on both sides. An air inlet hole 101 is opened above the installation groove 102 on one side of the filter screen seat 6.
[0024] By sliding the mounting base 5 containing the desiccant into the mounting slot 102, and then turning on the exhaust fan 8, outside air enters the food storage bin 1 through the air inlet 101. The desiccant absorbs the moisture in the air, and the dried air is then exhausted through the exhaust fan 8 and discharged from the exhaust vent 103. This ensures that the bird food inside the food storage bin 1 is stored in a dry and ventilated environment, preventing the bird food from becoming moldy and spoiled.
[0025] When using the ventilated, moisture-proof, and mildew-proof bird feeder, by pinching the sliding plates 10 on both sides of the bottom of the grain storage bin 1, the sliding plates 10 on both sides will drive the limiting plates 12 to move along the crossbar 9 towards the side that is closer to each other, and compress the spring 11, thereby causing the limiting plates 12 to move and be stored inside the groove 105. Then, the tray 3 is snapped into the bottom of the front side of the grain storage bin 1. Then, the pinching of the sliding plates 10 is released, so that the limiting plates 12, under the action of the spring 11, extend through to the outside of the grain storage bin 1 and are inserted into the corresponding limiting groove 302 on the inside of the tray 3, thereby fixing the tray 3 and making it convenient to disassemble the tray 3 for cleaning later.
[0026] After the tray 3 is fixed, the birdseed is stored inside the food storage bin 1. The birdseed then falls into the tray 3 through the food outlet 104, making it convenient for the birds to eat. The mounting base 5 containing the desiccant is then slidably installed inside the mounting slot 102. The exhaust fan 8 is then turned on, allowing outside air to enter the food storage bin 1 through the air inlet 101. The desiccant absorbs moisture from the air, and the dried air is then exhausted through the exhaust fan 8 and discharged through the exhaust vent 103. This ensures that the birdseed inside the food storage bin 1 is stored in a dry and ventilated environment, preventing the birdseed from becoming moldy and spoiled.
