Compared with the prior art, the invention has the beneficial effects that: in the initial state, the third spring is in a compressed state, and the driving bar is located at the rear limit position.

When the product is used, the shell of the product is placed on a horizontal plane, the handle is held by hands, the upper cover is removed, and the magnet a is separated from the magnet b. The sealing plate is removed and the outer ratchet bar is then pressed outwardly by the elongated rod to separate the outer ratchet bar from the outer pawl and the fourth spring is compressed, while the inner pawl is pressed outwardly by the other elongated rod to separate the inner pawl from the inner ratchet bar and the second spring is compressed. The progressive ring falls to a lower limit position under the action of gravity, all the slender rod bodies are removed, the inner pawl moves inwards under the action of the elastic force of the second spring, so that the inner pawl is pressed and meshed with the inner ratchet bar, meanwhile, the outer ratchet bar moves inwards under the action of the elastic force of the fourth spring, the outer pawl is pressed and meshed with the outer ratchet bar, and the sealing plate is installed again. The material bearing plate and the progressive ring are both provided with magnets, and the material bearing plate is kept synchronous with the progressive ring under the magnetic action and is positioned at the lower limit position in the inner cylinder body. After sufficient pet food is added into the inner barrel, the discharge door is opposite to the slope, the material pushing strip slides, the two ends of the material pushing strip are opposite to the driving strip, the upper cover is fastened downwards, and the upper cover and the shell are fixed relatively. At the moment, the third spring is in a compressed state, the pressing plate is under the elastic force action of the third spring, so that the material baffle plate is tightly abutted to the upper end of the inner cylinder, the lower end of the discharge door is abutted to the slope, and the inner cylinder is relatively sealed. The external dust and impurities and the like can not enter the inner barrel body, so that the internal pet food is relatively sanitary and not easy to damp, and the storage time of the pet food is prolonged to a certain extent.

When feeding, the pedal is stepped downwards (either manually or by training a pet), so that the inner cylinder body moves downwards and the first spring is compressed. The outer pawl and the outer ratchet bar of the progressive ring form a ratchet-pawl structure, the inner pawl and the inner ratchet bar on the progressive ring form a ratchet-pawl mechanism, and the progressive ring can only move upwards relative to the inner cylinder body. When the inner cylinder moves downwards to the limit position, the inner pawl is clamped with the next ratchet on the inner ratchet strip, and the position of the progressive ring relative to the shell is unchanged, namely the position of the material bearing plate relative to the shell is unchanged. When the pedal is released, the inner cylinder body moves upwards to the initial position under the action of the elastic force of the first spring, the inner ratchet bar drives the inner pawl to move upwards, the progressive ring moves upwards, the outer pawl is clamped with the next ratchet on the outer ratchet bar, the progressive ring rises relative to the position of the shell, and the material bearing plate rises relative to the shell. In the process of up-and-down movement of the inner cylinder, the striker plate slides up and down along the sealing groove under the action of the elastic force of the third spring and is always tightly abutted against the upper end of the inner cylinder, and the inner cylinder is kept in a sealing state.

In the process that the pedal is stepped on, the inner cylinder moves downwards, so that the first transmission gear moves downwards, the first transmission gear moves downwards and is meshed with the rack, and the first transmission gear rotates. The first transmission gear rotates to drive the second transmission gear to rotate, and the second transmission gear rotates to drive the third transmission gear to rotate; the third transmission gear rotates to drive the external gear to rotate in the positive direction. The pawls in the external gear and the ratchet gear on the cam form a ratchet and pawl structure, and when the external gear rotates in the forward direction, the cam rotates. The cam rotates to drive the rotating ring to move, so that the swinging strip rotates around the jack and slides along the sliding groove, and the transmission strip slides along the sliding groove. The driving strip slides to drive the driving strip to move, the driving strip magnetically attracts the magnet a through the magnet b, and then the material pushing strip slides along the guide groove. In the process that the pedal moves from the initial position to the lower limit position, the cam rotates for a circle, so that the material pushing strip moves from the rear limit position to the front limit position and then moves to the rear limit position. In the process that the pedal moves from the lower limit position to the initial position, the cam does not rotate, namely the pushing strip does not move due to the ratchet wheel ratchet pawl structure between the outer gear and the cam.

The pedal is stepped on in a reciprocating mode, the material bearing plate ascends step by step, pet grains on the material weighing plate are made to abut against the material pushing strips, meanwhile, the material pushing strips move in a reciprocating mode to stir the pet grains abutting against the material pushing strips, and the pet grains move towards the discharge door. When pushing away the material strip and moving forward for pet grain promotes the discharge door and makes the discharge door rotate around rotating hole, and pet grain gets into and enters into the guide pipe chute through the slope, and slides down along the guide pipe chute under the effect of gravity, falls into the feeding dish. When the pushing strip moves backwards, the discharging door swings downwards under the action of gravity, returns to the original position and is abutted to the slope. And after the pet food in the inner barrel is fed, adding the pet food again according to the steps.

According to the pet food feeding device, the inner barrel is arranged, and when the inner barrel moves up and down in a reciprocating manner, the inner barrel drives the material bearing plate to move upwards, so that pet food gradually moves upwards; meanwhile, in the reciprocating up-and-down moving process of the inner cylinder body, the first transmission gear is meshed with the rack, so that the first transmission gear rotates to drive the cam to rotate, the pushing strip reciprocates, pet grains which move upwards and are abutted against the pushing strip fall into the feeding disc through the material guide inclined tube under the pushing action, and the feeding purpose is achieved.

According to the invention, the upper cover is arranged, so that pet food can be added into the inner barrel body when the upper cover is removed; when the upper cover is fastened, the striker plate offsets with the upper end of the outer wall of the inner barrel under the elastic action of the third spring, and meanwhile, the discharge door offsets with the slope under the action of gravity, so that the inner barrel is relatively sealed, the pet food in the inner barrel is prevented from deteriorating, and the storage time is prolonged.

According to the invention, the discharge door is arranged, and the discharge door swings downwards under the action of gravity to abut against the slope in a natural state, so that the inner cylinder body is relatively sealed, the inner cylinder is relatively clean, pet grains are prevented from deteriorating, and the storage time is prolonged; when the pushing strip pushes the pet food outwards, the discharge door is opened under the pushing of the pet food, so that the pet food falls into the feeding tray through the blanking slope, and a new operation step is not added, namely the feeding process is completed.

The closure plate 9 is removed and the outer ratchet bar 71 is then pressed outwardly by the elongated rod so that the outer ratchet bar 71 is disengaged from the outer pawl 411 and the fourth spring 72 is compressed, while the inner pawl 42 is pressed outwardly by the other elongated rod so that the inner pawl 42 is disengaged from the inner ratchet bar 212 and the second spring 43 is compressed. The progressive ring 41 will fall to the lower limit position by gravity, and the inner pawl 42 will move inwardly under the elastic force of the second spring 43, so that the inner pawl 42 presses and engages with the inner ratchet bar 212, and the outer ratchet bar 71 will move inwardly under the elastic force of the fourth spring 72, so that the outer pawl 411 presses and engages with the outer ratchet bar 71, and the sealing plate 9 is reinstalled. The material bearing plate 31 and the progressive ring 41 are both provided with magnets, and the material bearing plate 31 is kept synchronous with the progressive ring 41 under the magnetic action and is positioned at the lower limit position in the inner cylinder 21. After sufficient pet food is added into the inner cylinder 21, the discharging door 64 is opposite to the slope 91, then the material pushing strip 65 is slid, two ends of the material pushing strip 65 are opposite to the driving strip 89, the upper cover 5 is fastened downwards, and the upper cover 5 and the shell 1 are fixed relatively. At this time, the third spring 62 is in a compressed state, the pressing plate 61 makes the striker plate 611 abut against the upper end of the inner cylinder 21 under the elastic force of the third spring 62, the lower end of the discharge door 64 abuts against the slope 91, and the inside of the inner cylinder 21 is relatively sealed. The external dust, impurities and the like can not enter the inner barrel body 21, so that the internal pet food is relatively sanitary and not easy to damp, and the storage time of the pet food is prolonged to a certain extent.

When feeding, the pedal 22 is stepped down (either manually or by a training pet), so that the inner cylinder 21 moves down and the first spring 23 is compressed. The outer pawl 411 and the outer ratchet bar 71 of the progressive ring 41 form a ratchet-pawl structure, and the inner pawl 42 and the inner ratchet bar 212 on the progressive ring 41 form a ratchet-pawl mechanism, so that the progressive ring 41 can only move upward relative to the inner cylinder 21. When the inner cylinder 21 moves downwards to the limit position, the inner pawl 42 will engage with the next ratchet on the inner ratchet bar 212, and the position of the progressive ring 41 relative to the housing 1 is unchanged, i.e. the position of the material bearing plate 31 relative to the housing 1 is unchanged. When the pedal 22 is released, the inner cylinder 21 will move upward to the initial position under the elastic force of the first spring 23, the inner ratchet bar 212 will drive the inner pawl 42 to move upward, so that the progressive ring 41 moves upward, and further the outer pawl 411 is engaged with the next ratchet on the outer ratchet bar 71, and the progressive ring 41 is raised relative to the position of the housing 1, that is, the material-bearing plate 31 is raised relative to the housing 1. In the process of the up-and-down movement of the inner cylinder 21, the striker plate 611 slides up and down along the sealing groove 631 under the elastic force of the third spring 62, and is always pressed against the upper end of the inner cylinder 21, so that the inner cylinder 21 maintains a sealing state.

When the pedal 22 is stepped on, the inner cylinder 21 moves downward, so that the first transmission gear 82 moves downward, and is engaged with the rack 811, so that the first transmission gear 82 rotates. The first transmission gear 82 rotates to drive the second transmission gear 83 to rotate, and the second transmission gear 83 rotates to drive the third transmission gear 84 to rotate; the third transmission gear 84 rotates to cause the external gear 85 to rotate in the normal direction. Pawls 851 in the external gear 85 and a ratchet gear 861 on the cam 86 constitute a ratchet pawl structure, and when the external gear 85 rotates in the forward direction, the cam 86 rotates. The rotation of the cam 86 will move the rotating ring 871, so that the swinging rod 87 rotates around the insertion hole 213 and slides along the sliding groove 872, so that the transmission rod 88 slides along the sliding groove 872. The driving bar 88 slides to drive the driving bar 89 to move, the driving bar 89 magnetically attracts the magnet a66 through the magnet b892, and then the material pushing bar 65 slides along the guide groove 632. During the process that the pedal 22 moves from the initial position to the lower limit position, the cam 86 rotates for a circle, so that the material pushing strip 65 moves from the rear limit position to the front limit position and then moves to the rear limit position. During the movement of the pedal 22 from the lower limit position to the initial position, the cam 86 does not rotate, i.e., the lifter bar 65 does not move, due to the ratchet and pawl structure between the external gear 85 and the cam 86.

When the pedal 22 is treaded in a reciprocating manner, the material bearing plate 31 gradually rises, so that the pet food on the material weighing plate 31 is abutted against the material pushing strip 65, and meanwhile, the material pushing strip 65 reciprocates to stir the pet food abutted against the material pushing strip 65, so that the pet food moves towards the discharge door 64. When the material pushing strip 65 moves forward, the pet food pushes the discharging door 64 to enable the discharging door 64 to rotate around the rotating hole 633, the pet food enters the material guiding inclined pipe 13 through the slope 91, and slides downwards along the material guiding inclined pipe 13 under the action of gravity to fall into the feeding disc 11. When the material pushing bar 65 moves backwards, the discharging door 64 swings downwards under the action of gravity, returns to the original position and abuts against the slope 91. When the pet food in the inner cylinder body 21 is fed, the pet food is added again according to the steps.

According to the invention, by arranging the inner cylinder 21, when the inner cylinder 21 reciprocates up and down, the inner cylinder 21 drives the material bearing plate 31 to move upwards, so that pet food gradually moves upwards; meanwhile, in the reciprocating up-and-down movement process of the inner cylinder 21, the first transmission gear 82 is meshed with the rack 811, so that the first transmission gear 82 rotates to further drive the cam 86 to rotate, further the material pushing strip 65 reciprocates, and pet grains which move upwards and are abutted against the material pushing strip 65 fall into the feeding disc 11 through the material guiding inclined tube 13 under the pushing action, and the feeding purpose is achieved.

According to the invention, the upper cover 5 is arranged, so that when the upper cover 5 is removed, pet food can be added into the inner barrel body 21; when the upper cover 5 is fastened, the material baffle 611 is pressed against the upper end of the outer wall of the inner cylinder 21 under the elastic action of the third spring 63, and meanwhile, the material outlet door 64 is pressed against the slope 91 under the action of gravity, so that the inner cylinder 21 is relatively sealed, pet food in the inner cylinder 21 is prevented from going bad, and the storage time is prolonged.

According to the invention, the discharge door 64 is arranged, and in a natural state, the discharge door 64 swings downwards under the action of gravity to abut against the slope 91, so that the inner cylinder 21 is relatively sealed, the inner cylinder 21 is relatively clean, pet grains are prevented from deteriorating, and the storage time is prolonged; when the pushing strip 65 pushes the pet food outwards, the discharging door 64 is opened under the pushing of the pet food, so that the pet food falls into the feeding tray 11 through the blanking slope 13, and a new operation step is not added, namely, the feeding process is completed.
