[0026] This invention proposes a pet feeder 100.

[0027] Please see Figures 1 to 4 In one embodiment of the present invention, the pet feeder 100 includes a food storage mechanism 1 and a food dispensing mechanism 2. The food storage mechanism 1 includes a food container 11 and a stirring element 12. The food container 11 has a food storage chamber 11a and a food outlet 11b communicating with the food storage chamber 11a. The stirring element 12 is rotatably disposed in the food storage chamber 11a to open or block the food outlet 11b. The stirring element 12 is used to stir the pet food in the food storage chamber 11a. The food dispensing mechanism 2 is disposed at the bottom of the food container 11. The food dispensing mechanism 2 includes a shell assembly 21 and a... The food dispensing component 22 and the shell assembly 21 are connected to the food container 11 and define a food dispensing chamber 21a that communicates with the lower food outlet 11b. The bottom of the food dispensing chamber 21a is provided with a food outlet 21b. The lower food outlet 11b and the food outlet 21b are offset in the vertical direction. The food dispensing component 22 is rotatably disposed in the food dispensing chamber 21a to push the pet food in the food dispensing chamber 21a to the food outlet 21b. When the stirring component 12 blocks the lower food outlet 11b, the stirring component 12 prevents the pet food in the food storage chamber 11a from falling into the food dispensing chamber 21a.

[0028] Understandably, when the pet feeder 100 is running, the stirring element 12 first rotates to open the food inlet 11b, and the pet food in the food storage chamber 11a falls evenly into the food dispensing chamber 21a under the stirring action of the stirring element 12. Subsequently, the food dispensing element 22 rotates in the food dispensing chamber 21a, separating the pet food that has fallen into the food dispensing chamber 21a and pushing it sequentially to the food outlet 21b, thus achieving quantitative food dispensing. When the preset amount of food is reached or no more food needs to be dispensed, the stirring element 12 rotates again to seal the food inlet 11b, preventing pet food from continuously falling into the food dispensing chamber 21a, effectively preventing excessive accumulation of pet food in the food dispensing chamber 21a and causing blockage. Meanwhile, since the food inlet 11b and the food outlet 21b are staggered in the vertical direction, the pet food will not fall directly to the food outlet 21b after falling from the food inlet 11b into the food distribution chamber 21a. Instead, it will be received and pushed by the food distribution component 22, which further ensures the orderliness and stability of the food dispensing.

[0029] It should be noted that in this embodiment, the stirring element 12 has various structures. For example, the stirring element 12 can be a stirring rod or a stirring impeller. When the stirring element 12 is a stirring rod, it can be configured as a rod-shaped structure extending radially along the food storage chamber 11a, and the length of the stirring rod is slightly smaller than the inner diameter of the food storage chamber 11a, so that the pet food in the food storage chamber 11a can be fully stirred during rotation, and when rotated to a specific angle, it can cooperate with the edge of the food outlet 11b to achieve sealing. When the stirring element 12 is a stirring impeller, it can include a hub and multiple blades spaced circumferentially along the hub. The outer ends of the blades can extend to the vicinity of the inner wall of the food storage chamber 11a, which can not only effectively stir the pet food and prevent clumping, but the structure of the blades themselves can also form a good shield when rotated to the position of the food outlet 11b, thereby reliably sealing the food outlet 11b. The structure of the stirring element 12 is not specifically limited here and can be adapted according to requirements.

[0030] Furthermore, in this embodiment, the food dispensing component 22 can also have various structures. For example, the food dispensing component 22 can be a food dispensing paddle or a food dispensing turntable 221. When the food dispensing component 22 is a food dispensing paddle, it can be configured as a sheet-like structure extending axially along the food dispensing cavity 21a. The number of paddles can be set to one or more according to the food dispensing volume requirement, and a small gap is left between the outer edge of the paddle and the inner wall of the food dispensing cavity 21a, so that when rotating with the drive shaft, the pet food falling into the food dispensing cavity 21a can be evenly dispensed to the food outlet 21b, avoiding pet food accumulation and blockage. When the food dispensing component 22 is a food dispensing turntable 221, multiple food dispensing grooves 21e evenly distributed circumferentially can be opened on its surface. The volume of the food dispensing grooves 21e can be designed according to the single food dispensing volume. The outer periphery of the turntable 221 is tightly fitted with the inner wall of the food dispensing cavity 21a, ensuring that the pet food can only enter the food outlet 21b through the food dispensing grooves 21e, thereby achieving precise quantitative dispensing. The specific structure of the food dispensing component 22 can also be flexibly selected and adjusted according to different actual application scenarios, as long as it can achieve the function of receiving and pushing pet food to the food outlet 21b.

[0031] With this design, the stirring element 12 can effectively agitate the pet food in the food storage chamber 11a during rotation, preventing it from clumping or blocking the food outlet 11b. It can also open and close the food outlet 11b, thus controlling the timing and amount of pet food falling. When the food outlet 11b is open, the evenly agitated pet food falls smoothly into the food distribution chamber 21a; when the food outlet 11b is closed, it prevents pet food from continuously falling into the food distribution chamber 21a, preventing excessive food accumulation and potential blockage. This ensures a smooth and stable food dispensing process and effectively solves the problem of food clogging in existing pet feeders 100.

[0032] In one implementation, such as Figures 6 to 9 As shown, the stirring component 12 includes a drive connection portion 121 and at least one stirring portion 122. The drive connection portion 121 is used for connection to a driver, and the stirring portion 122 is disposed on the drive connection portion 121. The drive connection portion 121 is configured to drive the stirring portion 122 to rotate to open or close the food inlet 11b and agitate the pet food in the food storage chamber 11a. It can be understood that in this embodiment, the drive connection portion 121 is a hub, which is used to connect to an external driver, while the stirring portion 122 is configured as a blade. The external driver can drive the stirring portion 122 to rotate through the drive connection portion 121 to agitate the food in the food storage chamber 11a. The number of stirring portions 122 can be one or more, and no specific limitation is made here.

[0033] The area of ​​each stirring part 122 projected onto the bottom wall of the food storage chamber 11a is larger than the opening area of ​​the food outlet 11b. The stirring part 122 is driven to rotate by the drive connection part 121. When the stirring part 122 rotates to a position opposite to the food outlet 11b, the stirring part 122 can completely cover and block the food outlet 11b, preventing the pet food from falling. When the stirring part 122 rotates away from the food outlet 11b, the food outlet 11b is in the open state. Under the action of its own gravity and the thrust generated by the stirring of the stirring part 122, the pet food in the food storage chamber 11a falls from the food outlet 11b into the food distribution chamber 21a.

[0034] The edge of the stirring section 122 can be arc-shaped or adapted to the shape of the food inlet 11b to improve the sealing effect of the food inlet 11b. Simultaneously, during rotation, it can more effectively stir the pet food in the food storage cavity 11a, preventing the pet food from accumulating in dead corners at the bottom of the food storage cavity 11a. Furthermore, the length and angle of the stirring section 122 can be designed according to the size and shape of the food storage cavity 11a to ensure that it can fully agitate the pet food in different locations within the food storage cavity 11a during rotation, further enhancing the anti-caking and anti-clogging effects.

[0035] In one implementation, such as Figure 9 As shown, the stirring component 12 includes multiple stirring sections 122, which are evenly arranged around the drive connection section 121. A food passage 12a is defined between adjacent stirring sections 122, connecting the food storage chamber 11a and the food outlet 11b. In one embodiment of the invention, three stirring sections 122 are evenly distributed around the drive connection section 121 to ensure stability and uniformity during stirring. The space between adjacent stirring sections 122 forms the food passage 12a. When the stirring component 12 rotates under the drive of the drive connection section 121, the three stirring sections 122 not only thoroughly stir the pet food in the food storage chamber 11a to prevent clumping, but also periodically align the food passage 12a between adjacent stirring sections 122 with the food outlet 11b, achieving quantitative food dispensing. This structural design makes the food dispensing process more stable and controllable, effectively adjusting the dispensing amount to meet the feeding needs of different pets. In some other embodiments of the present invention, the number of stirring parts 122 may be set to 1, 2, 4 or more, and no specific limitation is made here.

[0036] In one implementation, such as Figures 6 to 9As shown, one of the food storage chamber 11a and the drive connection part 121 is provided with a mounting hole 11c, and the other is provided with a plug-in part 123. The plug-in part 123 is rotatably inserted into the mounting hole 11c, and the stirring member 12 is detachably connected to the food container 11. It can be understood that, in this embodiment, by providing the mounting hole 11c and the plug-in part 123, a rotatable connection between the food container 11 and the base 4 can be achieved. When it is necessary to add pet food to the food storage chamber 11a, the user can rotate the food container 11 relative to the base 4 to rotate the opening of the food container 11 to a position that is convenient for adding, making the operation more convenient. At the same time, the detachable connection design between the plug-in part 123 and the food container 11 allows the food container 11 to be removed separately from the base 4, which facilitates thorough cleaning of the inside of the food container 11, avoids the spoilage and bacterial growth of residual pet food, and ensures the hygiene of the pet's diet.

[0037] Furthermore, the mounting hole 11c can be provided on the grain hopper 11 and the insertion part 123 can be provided on the stirring member 12, or the mounting hole 11c can be provided on the drive connection part 121 of the stirring member 12 and the grain hopper 11 can be provided with the mounting hole 11c. No specific limitation is made here, as long as the stirring member 12 can be rotated after insertion. The insertion part 123 and the mounting hole 11c are detachably connected so that the stirring component 12 can be disassembled and assembled with the grain container 11. There are various detachable structures for the insertion part 123 and the mounting hole 11c. For example, the insertion part 123 can be configured with a structure with elastic claws, and the inner wall of the mounting hole 11c is provided with a corresponding groove 211a. When the insertion part 123 is inserted into the mounting hole 11c, the elastic claws are engaged in the groove 211a to achieve fixation. When disassembling, pressing the elastic claws can pull the insertion part 123 out of the mounting hole 11c. Alternatively, a magnetic attraction method can be used, with magnets that attract each other set inside the insertion part 123 and the mounting hole 11c respectively, using magnetic force to achieve a detachable connection. Of course, when setting a detachable structure, it is necessary to ensure the stability of the stirring component 12 when rotating. The detachable structure of the insertion part 123 and the mounting hole 11c is not specifically limited here.

[0038] In one implementation, please refer to Figures 4 to 9A limiting part 124 is provided on one of the outer peripheral wall of the insertion part 123 and the inner wall of the mounting hole 11c, and a guide groove 11d is provided on the other. An avoidance groove 11e is provided at the end of the mounting hole 11c away from the grain storage cavity 11a. The limiting part 124 is rotatably provided in the avoidance groove 11e, and the guide groove 11d is used for the limiting part 124 to slide into or out of the avoidance groove 11e. In one embodiment of the present invention, one of the grain container 11 and the stirring component 12 is provided with a mounting hole 11c, and the other is provided with a plug-in portion 123. The plug-in portion 123 is rotatably disposed within the mounting hole 11c. One of the inner peripheral wall of the mounting hole 11c and the outer peripheral wall of the plug-in portion 123 is provided with a limiting portion 124, and the other is provided with a guide groove 11d and a clearance groove 11e communicating with the guide groove 11d. The guide groove 11d is used for the limiting portion 124 to slide into or out of the clearance groove 11e, so that the stirring component 12 and the grain container 11 can have a separated state and an assembled state. In the separated state, the plug-in portion 123 is disposed outside the mounting hole 11c; in the assembled state, the plug-in portion 123 is inserted into the mounting hole 11c, and the limiting portion 124 is rotatably disposed within the clearance groove 11e.

[0039] Understandably, when assembling the agitator 12 and the grain container 11, the insertion part 123 on one can be controlled to insert into the mounting hole 11c on the other, and the limiting part 124 is guided to slide along the guide groove 11d into the clearance groove 11e. The agitator 12 is used to connect with the grain driver 3. The grain driver 3 drives the agitator 12 to rotate around the axis of the mounting hole 11c. At this time, the limiting part 124 can rotate in the clearance groove 11e, and the groove wall of the limiting groove can abut and limit the limiting part 124, preventing the limiting part 124 from disengaging from the clearance groove 11e, thus achieving a stable connection. When separating the agitator 12 and the grain container 11, the agitator 12 is lifted upwards and the limiting part 124 is controlled to slide along the guide groove 11d, and finally the separation is completed.

[0040] It should be noted that, in this embodiment, the positions of the insertion part 123 and the mounting hole 11c are not specifically limited. For example, the mounting hole 11c can be located on the grain hopper 11 and the insertion part 123 can be located on the stirring member 12, or the mounting hole 11c can be located on the stirring member 12 and the insertion part 123 can be located on the grain hopper 11, as long as a detachable connection between the two can be achieved. Furthermore, a guide groove 11d and a clearance groove 11e can be provided on the inner peripheral wall of the mounting hole 11c, and a limiting part 124 protrudes from the outer peripheral wall of the insertion part 123, or the outer peripheral wall of the insertion part 123 can be provided with a guide groove 11d and a clearance groove 11e, and a limiting part 124 protrudes from the inner peripheral wall of the mounting hole 11c. Either method is acceptable and is not specifically limited here.

[0041] In one implementation, such as Figures 6 to 9As shown, the mounting hole 11c penetrates the bottom wall of the grain storage chamber 11a and is spaced apart from the grain outlet 11b. The stirring component 12 is provided with a plug-in part 123, which passes through the mounting hole 11c for connection with the driver. It can be understood that in this embodiment, the mounting hole 11c is opened on the bottom wall of the grain storage chamber 11a of the grain hopper 11. This mounting hole 11c penetrates the bottom wall, allowing the plug-in part 123 of the stirring component 12 to extend through the mounting hole 11c to the outside of the grain hopper 11, so as to connect with the output end of the grain driver 3 located below the grain hopper 11. This arrangement makes the layout of the drive structure more reasonable, avoids the driver occupying space in the grain storage chamber 11a, and also facilitates the assembly and maintenance of the driver and the stirring component 12.

[0042] In one implementation, such as Figures 6 to 9 As shown, a limiting part 124 is provided on the outer wall of the insertion part 123, and a guide groove 11d and a clearance groove 11e are provided on the inner wall of the mounting hole 11c. The clearance groove 11e is located at the end of the mounting hole 11c away from the grain storage chamber 11a, and the guide groove 11d connects the grain storage chamber 11a and the clearance groove 11e. It can be understood that in this embodiment, the limiting part 124 is provided on the outer wall of the insertion part 123, while the guide groove 11d and the clearance groove 11e are formed on the inner wall of the mounting hole 11c. The clearance groove 11e is located at the end of the mounting hole 11c away from the grain storage chamber 11a, and the guide groove 11d extends from the end of the mounting hole 11c near the grain storage chamber 11a to the clearance groove 11e, thereby connecting the grain storage chamber 11a and the clearance groove 11e.

[0043] When the agitator 12 needs to be installed on the grain hopper 11, the user inserts the connector 123 of the agitator 12 downwards into the mounting hole 11c from the grain storage chamber 11a. At this time, the limiting part 124 on the outer wall of the connector 123 will align with the entrance of the guide groove 11d at the upper end of the inner wall of the mounting hole 11c, allowing the limiting part 124 to slide downwards along the guide groove 11d and finally enter the clearance groove 11e located at the lower end of the mounting hole 11c. When the agitator 12 is working, it rotates around the axis of the mounting hole 11c, and the limiting part 124 rotates along with it in the clearance groove 11e. Since the groove wall of the clearance groove 11e forms a blockage against the limiting part 124 in the vertical direction, it can effectively prevent the agitator 12 from falling upwards during operation, ensuring the stability of the connection. When it is necessary to disassemble the agitator 12, simply slide the limiting part 124 back into the guide groove 11d from the clearance groove 11e, and then pull the agitator 12 upwards. The limiting part 124 can then slide upwards along the guide groove 11d and finally disengage from the mounting hole 11c, thus separating the agitator 12 from the grain hopper 11. This makes the installation and disassembly process very intuitive and convenient.

[0044] In one implementation, such as Figure 8As shown, the guide groove 11d extends spirally around the axis of the mounting hole 11c. It can be understood that in this embodiment, when the limiting part 124 slides along the guide groove 11d, it can simultaneously achieve axial movement and circumferential rotation of the insertion part 123. When the user inserts the insertion part 123 of the stirring member 12 into the mounting hole 11c and allows the limiting part 124 to enter the guide groove 11d, the stirring member 12 will naturally rotate as the limiting part 124 slides downward along the spiral guide groove 11d until the limiting part 124 slides into the clearance groove 11e. This spiral structure not only provides a smooth path for the sliding of the limiting part 124, but also pre-positions the stirring member 12 during installation, allowing the limiting part 124 to accurately engage in the preset position of the clearance groove 11e, reducing the difficulty of alignment during installation.

[0045] Furthermore, during the operation of the stirring component 12, it may move upwards. Even if the limiting part 124 enters the guide groove 11d, the spiral guide groove 11d wall can generate a circumferential reaction force on the limiting part 124, further enhancing the locking effect on the limiting part 124 and reducing the risk of the limiting part 124 accidentally sliding out of the avoidance groove 11e, thereby improving the stability of the overall structure. Compared with the straight guide groove 11d, the spirally extended guide groove 11d allows the limiting part 124 to have a larger contact area with the groove wall during sliding, dispersing the frictional force during sliding, reducing component wear, and extending service life.

[0046] In one implementation, such as Figures 6 to 9 As shown, there are three guide grooves 11d and three limiting parts 124, which are evenly distributed at 120-degree intervals along the circumference. This three-point positioning method can significantly improve the coaxiality of the mixing component 12 in the combined state, ensuring that the mixing component 12 rotates smoothly under the drive of the food driver 3, and reducing noise and vibration caused by eccentricity. At the same time, the cooperation of multiple limiting parts 124 with the clearance groove 11e is equivalent to forming multiple evenly distributed constraint points in the circumference, which further enhances the restriction on the axial movement of the mixing component 12. Even if the mixing component encounters the impact or jamming of pet food particles during the mixing process, it can effectively prevent the mixing component 12 from axially shifting or tilting, ensuring the stability and reliability of the mixing operation.

[0047] In one implementation, such as Figure 8 and Figure 9As shown, a mounting portion 111 protrudes from the bottom of the grain storage chamber 11a, and a mounting hole 11c penetrates the mounting portion 111. A slot 123b is provided on the insertion portion 123, and the mounting portion 111 is rotatably disposed within the slot 123b. It should be noted that in this embodiment, an annular slot 123b is provided on the side of the insertion portion 123 facing the bottom wall of the grain storage chamber 11a. The mounting portion 111 is located at the bottom of the grain storage chamber 11a and has a protruding cylindrical structure. When the stirring component 12 is installed in the grain hopper 11, the cylindrical mounting portion 111 is precisely inserted into the slot 123b and fits with the inner wall of the slot 123b with a clearance, allowing the mounting portion 111 to rotate smoothly within the slot 123b. Through the nested fit between the mounting portion 111 and the slot 123b, additional radial support is provided for the stirring component 12, further improving the stability of the stirring component 12 during rotation and effectively preventing the stirring component 12 from shaking or becoming eccentric due to uneven force.

[0048] In one implementation, please refer to Figures 4 to 9 The end of the insertion part 123 away from the drive connection part 121 is provided with a first mating part 123a, which is used for connection of the driver. It is understood that in this embodiment, the first mating part 123a is a hexagonal insertion hole. The grain driver 3 for driving the stirring member 12 to rotate includes a first transmission member 32, which is provided with a matching hexagonal first output shaft 321. When the stirring member 12 and the grain container 11 are in a combined state, the first output shaft 321 can be inserted into the hexagonal insertion hole. Through the circumferential limiting effect of the hexagonal structure, the power of the grain driver 3 can be stably and efficiently transmitted to the stirring member 12, avoiding slippage. Of course, the structure of the first mating part 123a is not limited to a hexagonal insertion hole; it can also be a D-shaped shaft hole 233a, a spline hole, or other structures that can achieve circumferential fixation. The output end of the driver is correspondingly set as a D-shaped shaft, spline shaft, etc., as long as the reliability of power transmission can be guaranteed; no specific limitation is made here.

[0049] In one implementation, such as Figure 5 , Figure 10 and Figure 11As shown, the pet feeder 100 also includes a food driver 3, and the housing assembly 21 further has a mounting cavity 21c. The mounting cavity 21c is located between the food storage cavity 11a and the food dispensing cavity 21a. The food driver 3 is located within the mounting cavity 21c and is drivenly connected to the stirring component 12 and the food dispensing component 22, respectively. It is understood that placing the mounting cavity 21c between the food storage cavity 11a and the food dispensing cavity 21a allows the food driver 3 to be compactly integrated inside the base 4, making full use of the space between the food storage cavity 11a and the food dispensing cavity 21a, while avoiding the driver being exposed, affecting the product's aesthetics, or being accidentally touched by the pet. The mounting cavity 21c also provides good protection for the food driver 3, reducing the corrosion of the driver by external dust and moisture, and extending its service life. The feed driver 3 is connected to the mixing component 12 and the feed distributing component 22 respectively. That is, the two components are driven to work simultaneously by a single driver. This integrated drive design not only simplifies the overall structure, reduces the number of parts, and reduces assembly difficulty and production cost, but also ensures the coordination of the actions of the mixing component 12 and the feed distributing component 22. For example, when the mixing component 12 opens the feed outlet 11b to discharge feed, the feed distributing component 22 performs the feed distributing operation at the same time, making the entire feeding process smoother and more efficient, and avoiding problems such as feed accumulation or feed discharging interruption.

[0050] Furthermore, in this embodiment, the grain driver 3 may be equipped with two motors for driving connection with the mixing component 12 and the grain distributing component 22, or it may be equipped with a single motor and connected through a transmission component. The grain driver 3 may drive the mixing component 12 and the grain distributing component 22 to operate synchronously, or it may be configured to selectively drive one of the mixing component 12 and the grain distributing component 22 to rotate. Its specific structure is not limited here.

[0051] In one implementation, such as Figure 2 and Figure 5As shown, the grain distribution chamber 21a includes a grain dropping channel 21d and a grain distribution trough 21e. The grain distribution component 22 is rotatably disposed in the grain distribution trough 21e. The upper end of the grain dropping channel 21d is connected to the grain outlet 11b, and the lower end of the grain dropping channel 21d is connected to the grain distribution trough 21e. The connection between the grain dropping channel 21d and the grain distribution trough 21e is offset from the grain outlet 21b in the vertical direction. It should be noted that, in this embodiment, the housing assembly 21 includes a mounting shell 211 and a food distribution cylinder 212. The mounting shell 211 and the food distribution cylinder 212 enclose a food distribution cavity 21a. The food distribution cavity 21a includes a food distribution trough 21e and a food dropping channel 21d communicating with the food distribution trough 21e. The mounting shell 211 has a mounting cavity 21c. The food dropping channel 21d is spaced apart from the mounting cavity 21c. The upper part of the mounting shell 211 is used to install the food bucket 11. The mounting cavity 21c of the mounting shell 211 is used to install the food driver 3. The upper end of the food dropping channel 21d is connected to the food outlet 11b of the food bucket 11. The pet food in the food bucket 11 enters the food dropping channel 21d through the food outlet 11b under the stirring of the stirring component 12, and finally falls into the food distribution trough 21e. The pet food in the food distribution trough 21e is discharged from the food outlet 21b under the pushing of the food distribution component 22.

[0052] The connection opening between the food drop channel 21d and the food distribution trough 21e and the food outlet 21b are staggered vertically. That is, the lower opening (connection opening) of the food drop channel 21d is not on the same vertical line as the position of the food outlet 21b within the food distribution trough 21e. This staggered design prevents pet food from falling directly from the food drop channel 21d into the food outlet 21b. Instead, a certain amount accumulates in the food distribution trough 21e before the food distribution component 22 pushes it out according to the preset feeding amount, thereby achieving precise control of the food dispensing amount.

[0053] In one implementation, such as Figures 10 to 12 As shown, the grain drive 3 includes a power source assembly 31, a first transmission component 32, and a second transmission component 33. The first transmission component 32 is connected to the stirring component 12, and the second transmission component 33 is connected to the grain distributing component 22. The power source assembly 31 drives the stirring component 12 to rotate via the first transmission component 32 and drives the grain distributing component 22 to rotate via the second transmission component 33. It should be noted that in this embodiment, the stirring component 12 is provided with a plug-in portion 123, and the bottom of the grain storage chamber 11a is provided with a mounting hole 11c for the plug-in portion 123 to be inserted. The first transmission component 32 can be inserted into the mounting hole 11c and connected to the plug-in portion 123. The bottom of the mounting chamber 21c is also provided with another through hole for the second transmission component 33 to extend into the grain distributing chamber 21a and drive the grain distributing component 22. A power source assembly 31 drives the first transmission component 32 and the second transmission component 33, which can drive the stirring component 12 and the grain distributing component 22 to rotate respectively, so that the power transmission paths of the stirring component 12 and the grain distributing component 22 are independent and will not interfere with each other, thereby realizing separate control of the two actions of stirring and distributing grain.

[0054] In one embodiment, the power source assembly 31 includes a ratchet 311, a first transmission member 32 and a second transmission member 33 respectively disposed on both sides of the ratchet 311 along the axial direction, the first transmission member 32 having a first pawl 315 connected to the ratchet 311, and the second transmission member 33 having a second pawl 316 connected to the ratchet 311, the ratchet 311 rotating clockwise to drive the stirring member 12 to rotate, and also driving the ratchet 311 counterclockwise to drive the grain distributing member 22 to rotate. Figures 10 to 12 As shown, the power source assembly 31 includes a ratchet 311, on which a first ratchet 3111 and a second ratchet 3112 are provided. The first ratchet 3111 and the second ratchet 3112 are arranged in opposite directions. A first pawl 315 is provided on a first transmission member 32, and a second pawl 316 is provided on a second transmission member 33. The first pawl 315 is connected to the first ratchet 3111, and the second pawl 316 is connected to the second ratchet 3112.

[0055] Understandably, when ratchet 311 rotates clockwise, the first ratchet tooth 3111 and the first pawl 315 mesh, thereby driving the first transmission component 32 to rotate clockwise. At this time, the second ratchet tooth 3112 and the second pawl 316 slip due to their opposite orientation, and the second transmission component 33 remains stationary, thus achieving independent drive of the stirring component 12. When ratchet 311 rotates counterclockwise, the second ratchet tooth 3112 and the second pawl 316 mesh, driving the second transmission component 33 to rotate counterclockwise. At this time, the first ratchet tooth 3111 and the first pawl 315 slip, and the first transmission component 32 remains stationary, thus achieving independent drive of the grain distributing component 22. By utilizing the unidirectional transmission characteristics of the ratchet tooth 311 and pawl, the power source component 31 can cleverly drive either the stirring component 12 or the grain distributing component 22. The structure is simple and compact, with high transmission efficiency, and has good reliability and durability, and can stably meet the independent control requirements of the grain feeding and distributing processes.

[0056] Of course, in some other embodiments, the grain driver 3 can also be located below the grain distributing mechanism 2, and the housing assembly 21 does not need to have a mounting cavity 21c. By setting the first transmission member 32 as an output shaft of a certain length, and the second transmission member 33 as a sleeve fitted over the first transmission member 32, the ratchet 311 drives the first transmission member 32 to rotate while keeping the second transmission member 33 stationary, or the ratchet 311 drives the second transmission member 33 to rotate on the first transmission member 32 while keeping the first transmission member 32 stationary, the independent driving of the stirring member 12 and the grain distributing member 22 can also be achieved. In this case, the ratchet and pawl can be located on the same side of the ratchet 311, and the two ratchets can be staggered to avoid interference between the two transmission members, so as to satisfy the independent driving of the stirring member 12 and the grain distributing member 22. The position of the grain driver 3 can be adapted according to the requirements, and no specific limitation is made here.

[0057] Furthermore, in one embodiment, such as Figure 12 As shown, the first transmission component 32 has a first groove 32a, within which a plurality of first pawls 315 are arranged at intervals around the first ratchet tooth 3111. In this embodiment, the first transmission component 32 has a circular first groove 32a on the side facing the ratchet 311. The plurality of first pawls 315 are rotatably disposed in the first groove 32a by screws, and the interval angle between adjacent first pawls 315 is equal, forming a uniformly distributed structure. The design of the multiple first pawls 315 arranged at intervals allows the multiple first pawls 315 to simultaneously contact the first ratchet tooth 3111 and transmit power when the ratchet 311 rotates clockwise, effectively dispersing the force borne by a single pawl, avoiding accelerated wear of the pawls or ratchet teeth due to excessive local force, thereby extending the service life of the power source component 31.

[0058] Furthermore, the second transmission member 33 has a second groove 33a, within which a plurality of second pawls 316 are provided. These second pawls 316 are arranged at circumferential intervals around the second ratchet 3112. It can be understood that in this embodiment, the second transmission member 33 has a circular second groove 33a on the side facing the ratchet 311. The plurality of second pawls 316 are rotatably disposed within the second groove 33a by screws, and the spacing angle between adjacent second pawls 316 is equal, forming a uniformly distributed structure. The arrangement structure of the second pawls 316 corresponds to the arrangement structure of the first pawls 315, and their driving structures are also the same, differing only in the direction of rotation. Further details are omitted here.

[0059] In one implementation, such as Figures 10 to 12 As shown, the power source assembly 31 also includes a drive motor 312 and a transmission gear 313. A ratchet 311 is circumferentially surrounded by a transmission gear 3113. The drive motor 312 is connected to the transmission gear 313, and the transmission gear 313 meshes with the transmission gear 3113 to drive the ratchet 311 to rotate clockwise or counterclockwise. It can be understood that in this embodiment, the transmission gear 3113 is a ring of teeth surrounding the ratchet 311. The output shaft of the drive motor 312 is fixedly connected to the transmission gear 313. When the drive motor 312 rotates clockwise, the transmission gear 313 drives the ratchet 311 to rotate clockwise, thereby driving the stirring component 12 to rotate through the engagement of the first ratchet tooth 3111 and the first pawl 315. When the drive motor 312 rotates counterclockwise, the transmission gear 313 drives the ratchet 311 to rotate counterclockwise, driving the grain distributing component 22 to rotate through the engagement of the second ratchet tooth 3112 and the second pawl 316.

[0060] By controlling the forward and reverse rotation of the drive motor 312, selective driving of either the stirring component 12 or the grain distributing component 22 is achieved, making operation simple and control precise. The transmission gear 313 and the transmission teeth 3113 on the ratchet 311 transmit power through gear meshing, which has the advantages of high transmission efficiency, stable transmission ratio, and reliable operation. This ensures that the power source component 31's power is stably transmitted to the ratchet 311, thereby guaranteeing the accuracy and consistency of the stirring and grain distributing actions.

[0061] In one implementation, such as Figure 14 and Figure 15 As shown, the food distributor 22 and the housing assembly 21 define multiple food distributor holes 22a within the food distributor cavity 21a. These holes 22a receive pet food falling from the lower food outlet 11b. The multiple food distributor holes 22a are arranged sequentially at intervals around the circumference of the food distributor 22. When the food distributor 22 rotates, the multiple food distributor holes 22a sequentially connect with the food outlet 21b. It can be understood that in this embodiment, the food distributor 22 divides the food distributor 21e into multiple food distributor holes 22a. When the food distributor 22 is rotated by the food driver 3, the multiple food distributor holes 22a sequentially pass below the food drop channel 21d to receive pet food from within the food drop channel 21d. Since the food distributor holes 22a are hollow holes with openings at the top and bottom, when the food distributor 22 pushes the pet food to move above the food outlet 21b, the food distributor holes 22a connect with the food outlet 21b, and the pet food falls out from the food outlet 21b.

[0062] It should be noted that the food dispensing component 22 has various structures. For example, the food dispensing component 22 can be a circular turntable 221 structure with multiple upwardly recessed fan-shaped grooves evenly arranged on its circumferential edge. Each fan-shaped groove and the inner wall of the food dispensing groove 21e together form the aforementioned food dispensing hole 22a. Alternatively, the food dispensing component 22 can also be a cylindrical structure with multiple radially extending partition plates. The partition plates divide the outer circumferential surface of the food dispensing component 22 into multiple independent spaces, each space constituting a food dispensing hole 22a. The number of food dispensing holes 22a can be designed according to the needs of a single feeding, for example, setting 3, 4, or 6 food dispensing holes 22a. The volume of each food dispensing hole 22a is approximately the same. When the food dispensing component 22 rotates by an angle of one food dispensing hole 22a, the pet food in one food dispensing hole 22a is conveyed to the food outlet 21b for discharge, thereby achieving quantitative food dispensing. This method of controlling the amount of grain dispensed by the number and volume of the grain dispensing holes 22a is simple and reliable. It can effectively avoid the impact of uneven grain particle size or changes in bulk density on the accuracy of grain dispensing, and ensure that the amount of grain fed each time is accurate and controllable.

[0063] In one implementation, such as Figure 14 and Figure 15As shown, the food dispensing component 22 includes a turntable 221 and a plurality of feeding brushes 222 evenly arranged around the circumference of the turntable 221. The plurality of feeding brushes 222 are disposed in the food dispensing cavity 21a, and any two adjacent feeding brushes 222 and the inner wall of the food dispensing cavity 21a define a food dispensing hole 22a. It should be noted that, in this embodiment, the food dispensing component 22 includes a turntable 221 and a plurality of feeding brushes 222 disposed around the turntable 221. The food dispensing component 22 is disposed in the food dispensing trough 21e, and a food dispensing hole 22a is defined between two adjacent feeding brushes 222 and the inner wall of the food dispensing trough 21e. When the food driver 3 drives the food dispensing component 22 to rotate, the pet food in the food drop channel 21d can fall into the plurality of food dispensing holes 22a.

[0064] Furthermore, the inner wall of the food dispensing trough 21e is equipped with a metering element 25. When the feeding brush 222 passes under the metering element 25, the metering element 25 can smooth out the pet food above each dispensing hole 22a, causing excess pet food to fall into the adjacent dispensing hole 22a. In this way, the pet food in each dispensing hole 22a can be metered. During the rotation of the food dispensing element 22, multiple feeding brushes 222 push the pet food in multiple dispensing holes 22a to the food outlet 21b in sequence and drop it out, thus completing the overall food dispensing operation.

[0065] In one implementation, such as Figure 15 As shown, the turntable 221 is provided with a second mating part 221a, which is used for connection of the driver. It should be noted that in this embodiment, the second transmission member 33 has a second output shaft 331 on the side away from the ratchet 311, and the grain dispensing member 22 has a second mating part 221a, which is detachably connected to the second output shaft 331. The second mating part 221a is also configured as a hexagonal insertion hole, and the second output shaft 331 has a corresponding hexagonal structure. The two are circumferentially fixed through shape matching, ensuring that the grain dispensing member 22 can rotate stably under the drive of the second output shaft 331 and accurately complete the grain dispensing action. Of course, in some other embodiments, the second mating part 221a can also be a spline hole located at the bottom of the stirring member 12, and the second output shaft 331 can be a corresponding spline shaft, as long as power transmission can be achieved; further details are not provided here.

[0066] In one implementation, such as Figure 3 As shown, the food container 11 is detachably connected to the housing assembly 21. It is understood that a snap-fit ​​structure is provided on the lower side wall of the food container 11, and a corresponding mating structure is provided on the mounting shell 211 of the housing assembly 21. Through the interlocking of the snap-fit ​​structure and the mating structure, quick assembly and disassembly of the food container 11 and the housing assembly 21 are achieved. This structure facilitates regular cleaning of the food container 11 by users to maintain internal hygiene, prevent pet food from becoming damp and moldy or breeding bacteria, and ensure the safety of pets' diet.

[0067] In one implementation, such as Figures 13 to 18 As shown, the mounting shell 211 and the grain dispensing cylinder 212 are detachably connected. It is understood that in this embodiment, the grain dispensing cylinder 212 includes an annular surrounding plate 2121 and a bottom plate 2122. The surrounding plate 2121 and the bottom plate 2122 are connected to form a grain dispensing trough 21e. The grain outlet 21b is located on the bottom plate 2122. The bottom of the mounting shell 211 is provided with multiple slots 211a, each slot 211a having an annular structure. The edge of the surrounding plate 2121 away from the bottom plate 2122 is folded outward to form a snap-fit ​​part 2121b. By rotating, the snap-fit ​​part 2121b is snapped into the slot 211a, enabling quick assembly and disassembly of the mounting shell 211 and the grain dispensing cylinder 212. This facilitates the user's cleaning and maintenance of components such as the grain dispensing component 22, the grain feeding brush 222, and the metering component 25 inside the grain dispensing chamber 21a, avoiding blockage or contamination problems caused by grain residue. Of course, in some embodiments of the present invention, the slot 211a may be provided on the surrounding plate 2121 and the snap-fit ​​part 2121b may be provided on the mounting shell 211. No specific limitation is made here, and the configuration can be adapted according to the requirements.

[0068] It should be noted that in some other embodiments, the enclosure plate 2121 and the mounting shell 211 have various detachable structures. For example, the outer wall of the enclosure plate 2121 is provided with external threads, and the mounting shell 211 is provided with internal threads at corresponding positions, so that the two are fixedly connected by thread engagement; or multiple locking protrusions are provided on the outer periphery of the enclosure plate 2121, and multiple locking slots are correspondingly provided on the mounting shell 211, so that the locking protrusions and locking slots engage to complete the assembly; or bolt connection can be used, with bolt holes provided at corresponding positions on the enclosure plate 2121 and the mounting shell 211, so that the two are fastened by bolts. The specific structure is not limited here.

[0069] Furthermore, an annular sealing ring 2124 is provided on the edge of the enclosure 2121 away from the bottom plate 2122, and an annular mounting groove 211c is provided on the bottom of the mounting shell 211. When the food dispenser 212 is connected to the mounting shell 211, the annular sealing ring 2124 is embedded in the mounting groove 211c. Through the tight fit between the annular sealing ring 2124 and the annular mounting groove 211c, the sealing performance between the mounting shell 211 and the food dispenser 212 can be effectively enhanced, preventing pet food crumbs or dust in the food dispensing chamber 21a from leaking out from the connection gap and avoiding contamination of other internal components of the pet feeder 100 or the external environment. At the same time, the sealing ring 2124 can also play a certain buffering role, reducing hard collisions between the mounting shell 211 and the food dispenser 212 during assembly or disassembly, protecting the components from damage and extending their service life.

[0070] In one implementation, such as Figures 1 to 3As shown, the pet feeder 100 also includes a base 4 located at the bottom of the food dispensing mechanism 2, which is detachably connected to the housing assembly 21. The base 4 is located below the food dispensing mechanism 2 to support the food dispensing mechanism 2 and the food storage mechanism 1, and the base 4 can accommodate a feeding bowl for receiving pet food from the food outlet 21b.

[0071] In addition, in one embodiment, a food container lid 13 is provided at the end of the food container 11 furthest from the food dispensing mechanism 2. The food container lid 13 is detachably connected to the food container 11 and is used to seal the opening of the food container 11, preventing dust, moisture, etc. from entering the food container 11 and contaminating the pet food. It also prevents the pet food from scattering when not in use. The food container lid 13 can be set in various ways, such as being connected to the food container 11 by a threaded connection or using a snap-on structure for quick opening and closing. When it is necessary to add pet food, the user only needs to unscrew or open the food container lid 13 to add food to the food container 11, which is convenient.

[0072] In one embodiment, the food storage mechanism 1 and the food dispensing mechanism 2 of the pet feeder 100 are designed to be detachable. Specifically, the food container 11 is detachably connected to the mounting shell 211, and the food dispensing mechanism 2 is also detachably connected to the base 4, meaning the mounting shell 211 and the base 4 are also detachably connected. This design allows the pet feeder 100 to be disassembled into multiple independent components, including the food container 11, the mounting shell 211, the food dispensing container 212, and the base 4. This greatly facilitates thorough cleaning and maintenance of each component by the user. Furthermore, the detachable structure of multiple components also facilitates modular production and assembly during manufacturing, reducing the complexity of the production process and improving production efficiency. In addition, when a component is damaged, the user only needs to replace the corresponding component, eliminating the need to replace the entire feeder, effectively reducing operating costs and aligning with environmental protection principles.

[0073] In one implementation, such as Figures 13 to 18 As shown, the grain distribution mechanism 2 also includes a grain blocking component 23, which is movably disposed on the housing assembly 21 for opening or blocking the grain outlet 21b. It should be noted that in this embodiment, the grain distribution cylinder 212 includes a surrounding plate 2121 and a bottom plate 2122. The surrounding plate 2121 is annularly arranged, and the bottom plate 2122 is connected to the surrounding plate 2121 and together defines the grain distribution chamber 21a. The grain outlet 21b is disposed on the bottom plate 2122. The grain blocking component 23 includes an annular rotating part 231 and a baffle 232 connected to the rotating part 231. The rotating part 231 is rotatably sleeved on the outside of the surrounding plate 2121, and the baffle 232 is disposed below the bottom plate 2122. At least a portion of the opening / closing actuator 24 is disposed outside the housing assembly 21 and drivenly connected to the rotating part 231, for driving the grain blocking component 23 to rotate relative to the housing assembly 21, so that the baffle 232 is used to open or block the grain outlet 21b.

[0074] In this embodiment, the enclosure plate 2121 and the bottom plate 2122 of the housing assembly 21 can be a separate structure or an integral structure. The upper opening of the food distribution trough 21e of the food distribution cylinder 212 is used to receive pet food from the food bucket 11. The food outlet 21b is provided on the bottom plate 2122 for food dispensing. The rotating part 231 and the baffle 232 of the food blocking part 23 are connected to form a cylindrical structure that matches the shape of the food distribution cylinder 212. The rotating part 231 is fitted on the outside of the enclosure plate 2121, and the baffle 232 is attached to the lower surface of the bottom plate 2122. The axes of the rotating part 231 and the enclosure plate 2121 coincide. When the opening and closing driver 24 drives the rotating part 231 to rotate around the axis, it can drive the baffle 232 to rotate to open or close the food outlet 21b. This configuration, by placing the food-blocking component 23 and at least part of the opening and closing actuator 24 outside the housing assembly 21, and forming a ring-shaped sleeve structure between the rotating part 231 and the surrounding plate 2121, effectively utilizes the space outside the housing assembly 21 to arrange the food-blocking component 23 and the opening and closing actuator 24. This avoids the problem of the drive mechanism occupying the internal space of the food dispensing chamber 21a in traditional designs, significantly reducing the overall volume of the food dispensing mechanism 2, and thus helping to reduce the overall size of the pet feeder 100. It should be noted that in this embodiment, the rotating part 231 can be a complete circular ring structure or an unclosed ring structure, as long as it can rotate circumferentially around the surrounding plate 2121. Its specific structure is not limited here. The shape and size of the baffle 232 can be designed according to the shape and size of the grain outlet 21b to ensure complete coverage and effective sealing. For example, the baffle 232 can be set as a fan shape or a circle that matches the diameter of the grain outlet 21b, and can be adapted according to requirements. By fitting the rotating part 231 onto the outside of the surrounding plate 2121, the installation of the grain blocking component 23 does not occupy the internal space of the grain distribution chamber 21a. Simultaneously, the ring-shaped design of the rotating part 231 ensures the stability of its rotation process, preventing the baffle 232 from shifting or jamming during movement, thus ensuring precise control of the grain outlet 21b.

[0075] In one implementation, such as Figure 16 and Figure 17As shown, one of the rotating part 231 and the surrounding plate 2121 is provided with a circumferentially extending groove 2121a, and the other is provided with a slider 2311. The slider 2311 is slidably disposed in the groove 2121a, so that the rotating part 231 is rotatably disposed on the surrounding plate 2121. It can be understood that, in this embodiment, by providing a matching structure of groove 2121a and slider 2311 between the rotating part 231 and the surrounding plate 2121, stable guidance and support can be provided for the rotation of the rotating part 231. Specifically, when the rotating part 231 is fitted onto the outside of the surrounding plate 2121, the slider 2311 is embedded in the sliding groove 2121a and can slide along the circumference of the sliding groove 2121a. This not only restricts the movement of the rotating part 231 along the axial direction of the surrounding plate 2121, ensuring that it always stays in the preset working position, but also effectively reduces the frictional resistance during the rotation process, making the rotation of the grain blocking part 23 smoother and more stable, and reducing the problem of inaccurate opening and closing of the grain outlet 21b due to shaking or jamming.

[0076] The circumferential length of the chute 2121a can be designed according to the required rotation angle of the baffle 232. For example, if the baffle 232 needs to rotate 90 degrees to fully open or block the grain outlet 21b, the circumferential length of the chute 2121a can be set to a 90-degree arc length, thereby limiting the rotation range of the rotating part 231 and preventing the baffle 232 from rotating excessively and damaging the mechanism or affecting the grain dispensing effect. This structure is simple and reliable, easy to process and assemble, and can effectively improve the overall stability and service life of the grain dispensing mechanism 2.

[0077] - In one implementation, such as Figure 16 and Figure 17 As shown, the outer side of the enclosure 2121 is provided with multiple grooves 2121a along the circumferential direction, and the inner side of the rotating part 231 is provided with multiple sliders 2311, which are distributed in the multiple grooves 2121a. It can be understood that in this embodiment, the number of grooves 2121a on the enclosure 2121 is set to 4 and evenly distributed along the circumference of the enclosure 2121, while the inner side of the rotating part 231 near the enclosure 2121 is provided with 4 sliders 2311. Each slider 2311 is arranged in a one-to-one correspondence with each groove 2121a. The shape of the slider 2311 is adapted to the groove shape of the groove 2121a. For example, if the groove 2121a is set as a T-shaped groove, the slider 2311 is set as a corresponding T-shaped structure to enhance the stability of the cooperation between the slider 2311 and the groove 2121a and prevent the slider 2311 from falling out of the groove 2121a.

[0078] By cooperating with multiple sliders 2311 and multiple grooves 2121a, the stability of the rotating part 231 during rotation can be further improved, the force generated during rotation can be distributed, and wear of a single groove 2121a or slider 2311 due to excessive force can be avoided, thereby extending the service life of the mechanism. Multiple evenly distributed sliders 2311 and grooves 2121a can also ensure that the center of gravity of the rotating part 231 is evenly distributed, reducing eccentric swaying during rotation, and making the opening and closing action of the baffle 232 on the grain outlet 21b more precise and reliable. Of course, in some other embodiments, the number of grooves 2121a can be set to 1, 2, 3, 5, or other numbers, while the number of sliders 2311 can be the same as or less than the number of grooves 2121a; no specific limitation is made here.

[0079] In one implementation, such as Figure 13 , Figure 15 , Figure 16 and Figure 18 As shown, the base plate 2122 is recessed in the direction away from the baffle 232 to form an annular positioning groove 2122a. The grain-blocking component 23 also includes a positioning boss 233 connected to the rotating part 231 and the baffle 232. The positioning boss 233 is rotatably disposed in the positioning groove 2122a. It can be understood that in this embodiment, the center position of the base plate 2122 is recessed into the grain-distributing cavity 21a to form a positioning groove 2122a. The positioning groove 2122a is frustum-shaped, and the positioning boss 233 is also a frustum matching the shape of the positioning groove 2122a. The lower end of the positioning boss 233 is connected to the inner wall of the rotating part 231 through the base plate 2122, and the upper end extends in the direction close to the base plate 2122 and is embedded in the positioning groove 2122a. The outer peripheral wall of the positioning boss 233 fits against the inner peripheral wall of the positioning groove 2122a. By cooperating with the positioning boss 233 and the positioning groove 2122a, the rotation center of the grain blocking component 23 can be further positioned to ensure the coaxiality of the rotating part 231 when rotating around the axis of the surrounding plate 2121, and to avoid the rotation axis of the grain blocking component 23 from shifting due to long-term use or vibration, thereby ensuring that the baffle 232 can be accurately aligned with the grain outlet 21b.

[0080] The large contact area between the positioning boss 233 and the positioning groove 2122a effectively disperses the radial force generated when the food blocking component 23 rotates, further improving the stability and smoothness of the rotation of the food blocking component 23, reducing the shaking of the baffle 232 during movement, and ensuring the accuracy of the opening and closing action of the food outlet 21b. In addition, the recessed design of the positioning groove 2122a means that part of the structure of the positioning boss 233 is located inside the food dispensing chamber 21a. However, since the positioning boss 233 is located at the center of the base plate 2122, and the food dispensing component 22 usually performs food dispensing operations in the circumferential area of ​​the food dispensing chamber 21a, this structure will not occupy the effective space for the food dispensing component 22 to push pet food, nor will it interfere with the food dispensing process.

[0081] In one implementation, such as Figure 16 and Figure 17 As shown, a downwardly extending limiting shaft 2123 is also provided in the positioning groove 2122a, and a shaft hole 233a is provided at the center of the positioning boss 233. The limiting shaft 2123 is rotatably disposed in the shaft hole 233a. It can be understood that in this embodiment, the limiting shaft 2123 protrudes downward from the center of the positioning groove 2122a, and a matching shaft hole 233a is provided at the top center of the positioning boss 233. The limiting shaft 2123 is inserted into the shaft hole 233a and has a clearance fit with the shaft hole 233a, so that the positioning boss 233 can rotate freely around the limiting shaft 2123. The cooperation between the limiting shaft 2123 and the shaft hole 233a forms the central shaft structure for the rotation of the grain-blocking component 23, further strengthening the positioning effect on the rotation axis of the grain-blocking component 23 and effectively preventing the grain-blocking component 23 from radially shifting or tilting during rotation. This dual positioning structure (positioning boss 233 and positioning groove 2122a cooperate, and limiting shaft 2123 and shaft hole 233a cooperate) can greatly improve the coaxiality and stability of the grain blocking component 23, ensuring that the baffle 232 can always accurately open or block the grain outlet 21b during long-term use, avoiding problems such as poor sealing of the grain outlet 21b or deviation in opening and closing position caused by axial offset.

[0082] In one implementation, such as Figure 13 , Figure 15 , Figure 16As shown, the grain distribution mechanism 2 also includes an opening / closing actuator 24 mounted on the mounting housing 211. A power connector 2312 is provided on the outer side of the rotating part 231, extending circumferentially around the rotating part 231. The opening / closing actuator 24 is driven to connect with the power connector 2312, thereby causing the rotating part 231 to rotate relative to the surrounding plate 2121. It is understood that in this embodiment, the power connector 2312 and the rotating part 231 can be configured as separate structures or as an integrally formed structure. Furthermore, the power connector 2312 can be configured as a gear ring, a transmission pulley, or a transmission protrusion, etc. For example, when the power connector 2312 is a gear ring, the inner side of the power connector 2312 is fixedly connected to the outer wall of the rotating part 231, forming a gear tooth structure on the outer side. The output end of the opening / closing actuator 24 is connected to a gear, which meshes with the gear ring. The opening / closing motor 241 drives the linkage gear 242 to rotate, thereby causing the gear ring and the rotating part 231 to rotate synchronously.

[0083] Alternatively, when the power connector 2312 is a transmission pulley, its outer peripheral wall has an annular transmission belt groove. The output end of the opening / closing actuator 24 is connected to the transmission pulley, and the transmission belt is wound between the transmission belt groove and the transmission pulley to realize the transmission of power. If the power connector 2312 is a transmission protrusion, it can be connected to the opening / closing actuator 24 through a crank-connecting rod mechanism or a cam mechanism to convert the linear or rotary motion of the opening / closing actuator 24 into the circumferential rotation of the rotating part 231. The design of the power connector 2312 extending circumferentially around the rotating part 231 ensures that the power of the opening / closing actuator 24 is evenly transmitted to the rotating part 231, avoiding excessive local stress that could cause deformation or damage to the rotating part 231. At the same time, it ensures the smoothness and accuracy of the rotation of the rotating part 231, thereby improving the reliability of the baffle 232 in controlling the opening and closing of the grain outlet 21b.

[0084] In one implementation, such as Figure 13 , Figure 15 , Figure 16 As shown, the power connector 2312 is a rack extending circumferentially along the rotating part 231. The opening and closing driver 24 includes an opening and closing motor 241 and a linkage gear 242 connected to the output end of the opening and closing motor 241. The linkage gear 242 meshes with the rack. It can be understood that in this embodiment, the power connector 2312 is a rack extending around the outer wall of the rotating part 231. Its extension angle can be set according to the required rotation stroke of the baffle 232. For example, when the baffle 232 needs to rotate 60 degrees to complete the opening and closing action of the grain outlet 21b, the circumferential extension angle of the rack can be set to 60 degrees accordingly. This can meet the rotation requirements of the grain blocking part 23 and avoid the waste of materials and space occupation caused by the rack being too long.

[0085] In one implementation, such as Figure 2 , Figure 13 and Figure 15 As shown, a mounting cavity 21c is formed inside the mounting housing 211. The start-stop motor 241 of the start-stop driver 24 is located inside the mounting cavity 21c. The linkage gear 242 is located outside the mounting cavity 21c and meshes with the rack on the rotating part 231. The mounting housing 211 is provided with a through hole 211b that communicates with the mounting cavity 21c. The output shaft of the start-stop motor 241 passes through the through hole 211b and is connected to the linkage gear 242 to drive the grain stop 23 to rotate.
