Description

Technical Field

[0001] The present application relates to the technical field of animal breeding equipment, and in particular to a timed and quantitative feeder for experimental animals. Background Art

[0002] In modern biomedical research, pharmacological experiments, animal behavior research and many other scientific fields involving experimental animals, dietary control of experimental animals is crucial. Accurate and regular feeding not only helps maintain the health of experimental animals, but is also one of the key factors to ensure the reliability and repeatability of experimental results. The existing experimental pet timed and quantitative feeders often have the following problems in their quantitative feeding structure during operation: First, the storage and feeding methods of feed both adopt a top-down gravity feeding method, which will cause the air between particles to be continuously compressed to form a dense structure, making it difficult to spread the feed at the bottom evenly, and the discharge channel is easily blocked by compacted feed. Especially when the ambient humidity is too high, the water absorption and expansion of the feed will further aggravate the jam, and the feed crumbs produced by the stacking method will sink to the bottom of the barrel, and gradually harden under the alternating action of temperature and humidity, forming stubborn stains that are difficult to remove. Frequent disassembly and cleaning will increase maintenance time and cost, and multiple disassembly and assembly will also cause mechanical wear. Summary of the Invention

The piston plate 33 will move upward in the gas storage tank 31 under the push of the gas, and part of the feed will reach the quantitative component 4 through the arc hole 22. The weighing plate 44 will weigh the feed transported here. When the weight accumulated on the weighing plate 44 is sufficient, the stroke of the two telescopic rods 42 will be increased. The weighing plate 44 will be pushed upward under the connection of the bent rod 43. At this time, the feed can enter the round shell 62 from the rubber tube 41.

[0026] The discharge assembly 6 includes a support block 61, a circular shell 62 is fixedly mounted on the top of the support block 61, a feed port 63 is opened on the outer edge of the circular shell 62, a second motor 64 is fixedly mounted on the back of the circular shell 62, an impeller 65 is fixedly connected to the output shaft of the second motor 64, and the impeller 65 is rotatably mounted inside the circular shell 62, a discharge hole 66 is fixedly connected to the right side of the circular shell 62, and a tray 67 is fixedly mounted on the right side of the discharge hole 66; the support block 61 is fixedly mounted on the front side of the base 51, and the feed port 63 is fixedly connected to one end of the rubber tube 41; Starting the second motor 64 can rotate the impeller 65, and the feed is delivered into the tray 67 through the discharge hole 66 by the action of centrifugal force.

The air passes through the arc hole 22 and the rubber tube 41 and reaches the circular shell 62, and then drives the impeller 65 to rotate, and the debris can be blown into the tray 67 for collection.

[0027] Working principle: When using the present invention, a control module is installed inside the device, which can preset the amount and time of each feeding. First, the top cover 25 is opened along the metal spring 24 by pulling the handle 26, and the feed is placed on the piston plate 33 in the cylinder 21. Then, the top cover 25 is closed. When the feed is placed for the first time, the piston plate 33 is at the bottom of the cylinder 21, and the feed does not exceed the height of the arc hole 22. When quantitative feeding is required, the gas storage tank 31 is started, and gas is filled into the cylinder 21 through the hose 32. The piston plate 33 moves upward in the gas storage tank 31 under the push of the gas, and part of the feed passes through the arc hole 22 and reaches the quantitative component 4. The weighing plate 44 weighs the feed transported there. When the weight is sufficient, the gas is withdrawn from the gas storage tank 31, the piston plate 33 falls, and feeding stops. When the feed is piled up on the top of the piston plate 33 and cannot be flattened, the first motor 52 can be started first. The rotation of the first motor 52 drives the three triangular blocks 54 to continuously vibrate the outer wall of the cylinder 21 to complete the flattening of the feed. When the cylinder 21 vibrates, it will repeatedly compress and restore the spiral piece 13, and the spiral piece 13 plays a role of limiting and supporting. When the weight accumulated on the weighing plate 44 is sufficient, the travel of the two telescopic rods 42 is increased, and the weighing plate 44 is pushed upward under the connection of the bent rod 43. At this time, the feed can enter the round shell 62 from the rubber tube 41. The second motor 64 is started to rotate the impeller 65, and the feed is discharged into the tray 67 through the discharge hole 66 under the action of centrifugal force. When the top of the cylinder 21 has been fed and the feed debris needs to be cleaned, the pull rope 34 can be reeled in by the two reeling blocks 36. At this time, the rotating rod 35 hoisted by the pull rope 34 will move upward until it passes over the arc hole 22 and stops. At this time, the air storage tank 31 will inject air into the cylinder 21 through the hose 32. The air will pass through the arc hole 22 and the rubber tube 41 and then reach the round shell 62, and then drive the impeller 65 to rotate. The debris will be collected in the tray 67, thereby performing pneumatic cleaning on the difficult-to-clean structure inside the equipment.
