Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a grain storage bucket. Background Technology

[0002] In daily life, various storage containers are commonly used to store grain. Existing grain storage devices include containers where rice can be dispensed directly from an opening at the top, and those with a rice outlet at the bottom controlled by a push-button switch to allow the grain to flow out. However, such storage containers are often complex in structure and require external control mechanisms. Utility Model Content

[0003] To solve the above technical problems, this application provides a grain storage bin that can be opened by simply rotating the bin body, making it easy to operate and simple in structure.

[0004] This application provides a grain storage bin, including a bin body with a grain storage cavity and a grain outlet for grain to flow out; a base movably connected to the bin body; and a linkage device movably mounted on the base. A first end of the linkage device covers the grain outlet, and a second end of the linkage device is drively connected to the bin body. The bin body is driven to move the linkage device relative to the base, causing the first end of the linkage device to move to a position offset from the grain outlet, thereby opening the grain outlet.

[0005] Technical benefits: The barrel body drives the linkage device to rotate, causing the first end of the linkage device to be misaligned with the grain outlet, thereby opening the grain outlet. This not only makes the operation simple, but also eliminates the need for a dedicated control switch to control the opening of the grain outlet. The structure is simple and the production cost is low.

[0006] In one possible implementation, the linkage device is rotatably connected to the base; the barrel is driven to rotate the linkage device relative to the base, causing the first end of the linkage device to move to a position misaligned with the grain outlet. In another possible implementation, a rotating part is provided between the first and second ends of the linkage device, and the rotating part is rotatably connected to the base; the barrel is driven to rotate the first end of the linkage device around the rotating part, causing the second end to rotate around the rotating part to a position misaligned with the grain outlet.

[0007] In one possible implementation, the rotating part is provided with a shaft hole extending axially along the rotation axis, and a support column is provided on the base, the support column being inserted into the shaft hole and rotatably connected to the shaft hole.

[0008] Technical effect: The support column is inserted into the shaft hole and cooperates with each other, so that the rotating part can rotate relative to the support column. At the same time, the support column can also support the rotating part, thereby supporting the entire linkage device. This allows the first end of the linkage device to bear a greater weight, preventing the first end of the linkage device from opening the grain outlet due to the gravity of the grain in the grain storage cavity, causing the grain to flow out. It also improves the sealing of the barrel.

[0009] In one possible implementation, a reset member is provided between the rotating part and the base. The reset member is used to store force when the barrel is driven to rotate the linkage device relative to the base, and to drive the linkage device to reset when the force is released so as to close the grain outlet again.

[0010] In one possible implementation, the reset element is a torsion spring, one end of which abuts against the linkage device and the other end against the base.

[0011] Technical effect: A reset component is set between the rotating part and the base. When the barrel is driven to rotate, the reset component is squeezed and stored by the rotating part and the base. When the grain outlet is opened and the use is finished, the barrel can automatically return to the initial position after the force is released, which saves effort and reduces the number of operation steps for the operator.

[0012] In one possible implementation, the base is provided with a first limiting structure, which is used to limit the maximum displacement of the first end around the rotating part.

[0013] Technical effect: The first limiting structure can limit the maximum displacement of the rotating part, preventing the linkage device from failing due to excessive rotation distance. At the same time, when the rotating part rotates to the first limiting structure, the first limiting structure forms a blocking effect, reducing unnecessary rotation by the operator and improving the user experience.

[0014] In one possible implementation, the first limiting structure is a limiting plate protruding from the inner wall of the base. In another possible implementation, the barrel is rotatably connected to the base, and the barrel is driven to rotate relative to the base, causing the linkage device to move relative to the base, so that the first end of the linkage device moves to a position misaligned with the grain outlet.

[0015] In one possible implementation, the second end of the linkage device is provided with a driven part, and the barrel body is provided with an abutting part; when the barrel body is driven to rotate relative to the base until the abutting part abuts against the driven part, it drives the driven part to rotate, thereby driving the linkage device to rotate relative to the base, so that the first end of the linkage device moves to a position misaligned with the grain outlet.

[0016] In one possible implementation, a slot is provided on the barrel body, and the driven part extends toward the barrel body and is inserted into the slot; the sidewall of the slot forms the abutment part.

[0017] Technical effect: The driven part is inserted into the slot and forms abutment with the slot wall, which facilitates the assembly between the driven part and the slot.

[0018] In one possible implementation, the base includes a top plate and a support base, the top plate being disposed on top of the support base, and the second end of the linkage device passing through the top plate and connected to the barrel body.

[0019] In one possible implementation, the base includes a second limiting structure for limiting the maximum displacement of the second end of the linkage device.

[0020] In one possible implementation, the top plate is provided with a sliding hole, and the second end of the linkage device is provided with a driven part. The driven part passes through the sliding hole and is connected to the barrel body for transmission. The two ends of the sliding hole form a second limiting structure.

[0021] In one possible implementation, the grain outlet is located at the bottom of the grain storage chamber, and the barrel body also includes a snap-fit ​​part, which is located at and fixedly connected to the grain outlet. The base has a through hole corresponding to the grain outlet, and the snap-fit ​​part passes through the through hole and snaps onto the bottom wall of the through hole.

[0022] In one possible implementation, the base includes a top plate and a support base. The top plate is disposed on top of the support base, and a gap is provided between the top plate and the support base. A through hole is provided on the top plate. The snap-fit ​​part snaps into the bottom wall of the through hole and can move within the gap, allowing the bucket and the base to rotate relative to each other. Technical effect: The snap-fit ​​part connects the bucket and the base, improving the connection stability between them and preventing the bucket from separating from the base during rotation. Simultaneously, the gap between the top plate and the support base provides rotational space for the snap-fit ​​part within the base, effectively improving the rotational efficiency between the bucket and the base.

[0023] In one possible implementation, one of the base and the barrel is provided with a rotating device, and the other of the base and the barrel is provided with a rotating ring, with the rotating device abutting against the rotating ring. When the barrel is driven to rotate, the rotating device and the rotating ring rotate relative to each other, preventing the barrel and the base from rubbing against each other and causing difficulty in rotation.

[0024] In one possible implementation, the rotating device includes a rotating disk and a rolling element, the rolling element being movably disposed on the rotating disk and abutting against the rotating ring.

[0025] In one possible implementation, each of the rotating disks is provided with a receiving hole, and the rolling element is disposed in the receiving hole and protrudes from both ends of the receiving hole.

[0026] In one possible implementation, the rotating device further includes a third limiting structure, in which the rotating disk is disposed and can rotate relative to the third limiting structure.

[0027] In one possible implementation, the bottom wall of the limiting structure is further provided with a rotating guide rail, and one end of the rolling element contacts the rotating guide rail and can roll along the rotating guide rail.

[0028] In one possible implementation, the rotating ring has a rolling groove that mates with the rolling element, and when the barrel is driven to rotate, the other end of the rolling element rolls along the rolling groove.

[0029] Technical effect: A rolling element is installed in the receiving hole of the rotating disc, with both ends of the rolling element extending out of the receiving hole. The rotating groove on the rotating ring abuts against one end of the rolling element, so that when the barrel is driven to rotate, the rolling element can roll along the rotating groove, preventing slippage and misalignment between the rotating ring and the rotating device. At the same time, since there is a rotating guide rail on the base, the other end of the rolling element can roll on the rotating guide rail, reducing the friction between the barrel and the base during rotation and improving the rotation efficiency.

[0030] In one possible implementation, the base further includes a rice-collecting cavity, which is connected to the grain outlet to receive the grain flowing out of the grain outlet.

[0031] Technical benefits: When taking rice, the user can place the container holding the rice into the rice taking chamber. Since the rice taking chamber is connected to the grain outlet, when the bucket is driven to open the grain outlet, the grain in the grain storage chamber can flow directly into the container. The operation is simple and convenient.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] The following is for reference. Figures 1 to 7 Description of a grain storage bin according to an embodiment of the present utility model

[0049] like Figures 1 to 3 As shown, this utility model provides a grain storage bin, including a bin body 10, a grain storage cavity inside the bin body 10, and a grain outlet 11 for grain to flow out; a base 30, which is movably connected to the bin body 10; and a linkage device 40, which is movably mounted on the base 30. The first end 41 of the linkage device 40 covers the grain outlet 11, and the second end 42 of the linkage device 40 is drively connected to the bin body 10. The bin body 10 is driven to move the linkage device 40 relative to the base 30, so that the first end 41 of the linkage device 40 moves to a position that is misaligned with the grain outlet 11, so as to open the grain outlet 11.

[0050] The grain storage chamber is a cavity inside the grain storage container. It can be a single, independent chamber or multiple separate chambers. Whether it is a single chamber or multiple chambers, each has a grain outlet 11 at its bottom. The grain storage container provides storage space for grain. The shape of the grain storage chamber can be, but is not limited to, cylindrical, prismatic, etc. The grains mentioned above can include, but are not limited to, rice, wheat, beans, etc.

[0051] The barrel body 10 can refer to a barrel-shaped structure with a cavity in the middle, forming a grain storage cavity for placing grain. The top of the barrel body 10 can be provided with an opening for putting grain into the grain storage cavity, and can also be provided with a lid for closing the opening. The lid can be detachable or flip-top type, and there is no limitation here.

[0052] See Figure 3The linkage device 40 can be a plate-shaped structure connected to the barrel 10. The first end 41 of the linkage device 40 is wider, and its size can close the grain outlet 11. The second end 42 and the middle part of the linkage device 40 are narrower, which can save materials and reduce space utilization.

[0053] The linkage device 40 can also be a rod-shaped structure, with a sealing plate at one end of the rod-shaped structure. The sealing plate forms the first end 41 of the linkage device 40 to seal the grain outlet 11.

[0054] The barrel 10 is connected to the second end 42 of the linkage device 40. When the barrel 10 is driven to rotate, the base 30 will not rotate with the barrel 10. Meanwhile, the grain outlet 11 is located at the center of the bottom of the barrel 10. When the barrel 10 is driven to rotate, although the grain outlet 11 will rotate accordingly, its position relative to the base 30 remains unchanged. The barrel 10 can drive the second end 42 of the linkage device 40 to rotate relative to the base 30. Since the first end 41 and the second end 42 are different positions of the same structure, the rotation of the second end 42 drives the first end 41 to rotate, causing a misalignment between the first end 41 and the grain outlet 11, thereby opening the grain outlet 11.

[0055] Understandably, users can control the flow rate and volume of grain by rotating the barrel 10 a certain distance and for a certain period of time. This design is not only simple to operate, but also eliminates the need for a dedicated control switch to control the opening of the grain outlet 11. It has a simple structure and low production cost.

[0056] In one possible implementation, such as Figures 1 to 4 As shown, the linkage device 40 is rotatably connected to the base 30; the barrel 10 is driven to rotate the linkage device 40 relative to the base 30, so that the first end 41 of the linkage device 40 moves to a position that is misaligned with the grain outlet 11.

[0057] The linkage device 40 is rotatably connected to the base 30. The linkage device 40 can be connected to the base 30 via a rotating part 43. The rotating part 43 can be a movable part located between the linkage device 40 and the base 30, or it can be a fixed part connected to either the linkage device 40 or the base 30. The other end of the fixed part can rotate relative to the other of the linkage device 40 or the base 30. This rotatable connection between the linkage device 40 and the base 30 prevents excessive friction between them when the barrel 10 rotates, thus avoiding any impact on the rotation effect.

[0058] In one possible implementation, a rotating part 43 is provided between the first end 41 and the second end 42 of the linkage device 40, and the rotating part 43 is rotatably connected to the base 30; the barrel 10 is driven to rotate the first end 41 of the linkage device 40 around the rotating part 43, so that the second end 42 rotates around the rotating part 43 to a position that is misaligned with the grain outlet 11.

[0059] refer to Figure 3 A rotating part 43 is provided between the first end 41 and the second end 42 of the linkage device 40. The rotating part 43 connects the linkage device 40 and the base 30. In this way, the rotating part 43 can prevent the first end 41 of the linkage device 40 from closing or opening the grain outlet 11, and can also reduce the impact on the rotation between the second end 42 and the barrel 10, thereby improving the rotation efficiency of the barrel 10.

[0060] It is understood that the rotating part 43 can be a connecting rod connecting the first end 41 and the second end 42, or it can be a connecting plate or other connecting parts, and no specific restrictions are made here.

[0061] In one possible implementation, the rotating part 43 is provided with a shaft hole extending axially along the rotation axis, and a support column is provided on the base 30. The support column is inserted into the shaft hole and rotatably connected to it. The support column and the shaft hole cooperate with each other, allowing the rotating part 43 to rotate relative to the support column. At the same time, the support column also supports the rotating part 43, thereby supporting the entire linkage device 40. This allows the first end 41 of the linkage device 40 to bear a greater weight, preventing the first end 41 of the linkage device 40 from opening the grain outlet 11 due to the gravity of the grain in the grain storage cavity, causing the grain to flow out. It also improves the sealing performance of the barrel 10.

[0062] In one possible implementation, a reset member 50 is provided between the rotating part 43 and the base 30. The reset member 50 is used to store force when the barrel 10 is driven to rotate relative to the base 30, and to drive the linkage device 40 to reset when the force is released so as to close the grain outlet 11 again.

[0063] In the above scheme, the reset element 50 can be an elastic element, which is located between the rotating part 43 and the base 30. When the barrel 10 is driven to rotate relative to the base 30, the elastic element is compressed and thus stores energy. When the barrel 10 is unloaded, the elastic element returns to its initial state. During the return process, it drives the linkage device 40 to reset and thus closes the grain outlet 11. The elastic element can be a spring, torsion spring, or other structural component that can provide restoring force.

[0064] In the above scheme, the reset member 50 can also be a non-elastic member. The reset member 50 can be an inclined structure provided between the rotating part 43 and the base 30. The inclined structure has an inclined surface that cooperates with the rotating part 43. When the barrel 10 is driven to rotate the linkage device 40 relative to the base 30, the rotating part 43 moves to a higher position along the inclined surface of the inclined structure, so that there is a height difference between the position of the rotating part 43 and the position of the linkage device 40 when closing the grain outlet 11. When the barrel 10 is unloaded, the rotating part 43 can return to the initial position along the inclined surface under the action of the weight of the barrel 10, and then close the grain outlet 11 again.

[0065] The reset element 50 is positioned between the rotating part 43 and the base 30. When the barrel 10 is driven to rotate the rotating part 43 relative to the base 30, the base 30 does not rotate, while the rotating part 43 rotates. This allows the reset element 50 to be compressed under the action of the rotating part 43, thus accumulating energy. When the barrel 10 is decompressed, the accumulated energy, without any other force obstructing it, can drive the linkage device 40 to reset to its initial state, thereby closing the grain outlet 11 again. This reduces the operator's steps and effectively improves the user experience.

[0066] In one possible implementation, the reset element 50 is a torsion spring, with one end abutting against the linkage device 40 and the other end abutting against the base 30.

[0067] The torsion spring can be a double-body torsion spring. The main structure of the double-body torsion spring can be connected to the linkage device 40 or to the base 30. The double-body torsion spring includes two torsion arms, one of which abuts against the linkage device 40, and the other torsion arm is connected to the base 30.

[0068] The torsion spring can also be a multi-body torsion spring, that is, a torsion spring with two or more torsion arms, with two or more torsion springs in equal numbers abutting against the linkage device 40 and the base 30 respectively. It is understood that since the size of the barrel 10 can vary according to actual design requirements, the weight that different sizes of barrels 10 can bear is not the same, and the restoring force required for the barrel 10 to return to its initial state after being driven to rotate is also different. Therefore, it is obvious to select torsion springs with different numbers of torsion arms and different torques for barrels 10 of different sizes. Therefore, those skilled in the art can select different types of torsion springs for manufacturing based on different sizes of barrels 10, and ordinary consumers can also choose different sizes of barrels 10 according to their actual usage needs.

[0069] One end of the torsion spring abuts against the linkage device 40, and the other end abuts against the base 30. When the barrel 10 is driven to rotate, the two ends of the torsion spring are squeezed and contracted by the rotating part 43 and the base 30 to store force. When the grain outlet 11 is opened and used, the two ends of the torsion spring of the barrel 10 can drive the linkage device 40 to return to the initial state under the action of the restoring force, and then close the grain outlet 11 again. In this way, the operator does not need to rotate the barrel 10 again to make the barrel 10 return to the initial state, reducing the operator's operation steps and improving the user experience.

[0070] In one possible implementation, the base 30 is provided with a first limiting structure 60, which is used to limit the maximum displacement of the first end 41 rotating around the rotating part 43.

[0071] The first limiting structure 60 can be a blocking member set on the base 30. The blocking member is set in the rotation direction of the linkage device 40. When the barrel 10 is driven to rotate the linkage device 40, the blocking member can limit the rotation range of the linkage device 40.

[0072] Understandably, the maximum displacement of the first end 41 of the linkage device 40 is the displacement of the first end 41 when it is completely offset from the grain outlet 11. At this point, the first end 41 neither affects the normal flow of grain from the grain outlet 11 nor causes the linkage device 40 to rotate too far. This reduces unnecessary operations by the operator and prevents the linkage device 40 from failing due to excessive rotation distance, thus improving the reliability of the grain storage tank.

[0073] In one possible implementation, refer to Figure 4 The first limiting structure 60 is a limiting plate that protrudes from the inner wall of the base 30.

[0074] It is understandable that the limiting plate can be a protruding structure integrated with the base 30, or it can be fixed to the base 30 through a snap-fit, slot or other structure. No specific restrictions are made here.

[0075] The limiting plate is a plate positioned along the rotation direction of the linkage device 40. The limiting plate can be positioned on the base 30 on one side of the linkage device 40, or on the base 30 on both sides of the linkage device 40. The direction in which the barrel 10 is driven to rotate can be one direction or two opposite directions. When the barrel 10 is driven to rotate in either of the two opposite directions, the limiting plate in either direction can limit the maximum displacement of the linkage device 40, that is, limit the maximum displacement of the first end 41. In this way, the operator can rotate in any direction, without having to rotate in a fixed direction, thus making the grain storage barrel more convenient to use.

[0076] In one possible implementation, the barrel 10 is rotatably connected to the base 30. The barrel 10 is driven to rotate relative to the base 30, which in turn drives the linkage device 40 to move relative to the base 30, so that the first end 41 of the linkage device 40 moves to a position that is misaligned with the grain outlet 11.

[0077] It is understandable that the barrel 10 and the base 30 can rotate relative to each other. When the barrel 10 is driven, the base 30 does not rotate while the barrel 10 rotates. Since the barrel 10 is connected to the second end 42 of the linkage device 40, when the barrel 10 rotates, it drives the linkage device 40 to rotate relative to the base 30, thereby causing the first end 41 of the linkage device 40 to move to a position misaligned with the grain outlet 11. In this way, the rotation of the barrel 10 can prevent the base 30 from moving and thus affecting the opening of the grain outlet 11, improving the user experience.

[0078] In one possible implementation, the second end 42 of the linkage device 40 is provided with a driven part 44, and the barrel 10 is provided with an abutting part; when the barrel 10 is driven to rotate relative to the base 30 until the abutting part abuts against the driven part 44, it drives the driven part 44 to rotate, thereby driving the linkage device 40 to rotate relative to the base 30, so that the first end 41 of the linkage device 40 moves to a position that is misaligned with the grain outlet 11.

[0079] Understandably, when the barrel 10 is not driven, there is no contact between the contact part and the driven part 44. Thus, since there is a certain distance between the contact part and the driven part 44 when the barrel 10 is not driven, accidental contact that could cause the grain outlet 11 to open can be avoided, thereby improving the reliability of the grain storage barrel.

[0080] In the above-described embodiments, the driven part 44 may be a portion extending from the second end 42, or it may be another structural member disposed on the second end 42 and connected to the second end 42. The abutting part of the barrel 10 may be a structural member protruding from the inner wall of the barrel 10, or it may be a groove disposed on the inner wall of the barrel 10.

[0081] It is understandable that when the abutting part is a protruding structure protruding from the inner wall of the barrel 10, when the barrel 10 is driven to rotate, the protruding structure rotates to the driven part 44 and abuts against the driven part 44, causing the driven part 44 to rotate, and then causing the linkage device 40 to rotate relative to the base 30, so that the first end 41 of the linkage device 40 moves to a position that is misaligned with the grain outlet 11.

[0082] It is understandable that when the slide groove is set on the inner wall of the barrel 10, the driven part 44 is at least partially inserted into the slide groove. When the barrel 10 is driven to rotate, the side wall of the slide groove and the driven part 44 form an abutment, which drives the driven part 44 to rotate, thereby driving the linkage device 40 to rotate relative to the base 30, so that the first end 41 of the linkage device 40 moves to a position that is misaligned with the grain outlet 11.

[0083] In one possible implementation, a slot is provided on the barrel 10, and the driven part 44 extends toward the barrel 10 and is inserted into the slot; the side wall of the slot forms an abutment part.

[0084] In the above scheme, the driven part 44 can be partially inserted into the slot or fully inserted into the slot. After the driven part 44 is inserted into the slot, it can contact the bottom wall of the slot or not.

[0085] Understandably, a slot is provided on the barrel 10, and the driven part 44 extends towards the barrel 10 and inserts into the slot. The driven part 44 is at least partially inserted into the slot. When the barrel 10 is driven to rotate, until the side wall of the slot abuts against the driven part 44, the driven part 44 rotates, which in turn drives the linkage device 40 to rotate relative to the base 30. This causes the first end 41 of the linkage device 40 to move to a position misaligned with the grain outlet 11, thereby opening the grain outlet 11. This slot design can save material costs. At the same time, with one end of the driven part 44 inserted into the slot, the abutment between the driven part 44 and the side wall of the slot during rotation is more stable, preventing slippage that would prevent the barrel 10 from driving the rotating device 14 to rotate.

[0086] In one possible implementation, refer to Figures 3 to 5 The base 30 includes a top plate 31 and a support base 32. The top plate 31 is located on top of the support base 32. The second end 42 of the linkage device 40 passes through the top plate 31 and is connected to the barrel 10.

[0087] In the above-described design, the base 30 consists of a top plate 31 and a support base 32. The top plate 31 is located at the bottom of the support base 32, and the second end 42 of the linkage device 40 passes through the top plate 31 and connects to the barrel 10. This means the linkage device 40 is positioned between the top plate 31 and the support base 32, thus limiting the movement of the linkage device 40 and reducing its swaying during use. Furthermore, since only the second end 42 of the linkage device 40 passes through the top plate 31 and connects to the barrel 10, interference between the bottom of the barrel 10 and other structures of the linkage device 40 during rotation is reduced, thus minimizing interference with the opening and closing of the grain outlet 11 and improving the reliability of the grain storage barrel.

[0088] In one possible implementation, refer to Figure 4 The base 30 includes a second limiting structure, which is used to limit the maximum displacement of the second end 42 of the linkage device 40.

[0089] Understandably, the maximum displacement of the second end 42 of the linkage device 40 is the displacement of the second end 42 when the first end 41 is completely offset from the grain outlet 11. At this point, the first end 41 neither affects the normal flow of grain from the grain outlet 11 nor causes the rotation distance of the second end 42 of the linkage device 40 to be too large. This reduces unnecessary operations by the operator and prevents the linkage device 40 from failing due to excessive rotation distance, thus improving the reliability of the grain storage tank.

[0090] In one possible implementation, refer to Figure 3 , Figure 4 and Figure 5 The top plate 31 is provided with a sliding hole 311, and the second end 42 of the linkage device 40 is provided with a driven part 44. The driven part 44 passes through the sliding hole 311 and is connected to the barrel 10 for transmission. The two ends of the sliding hole 311 form a second limiting structure.

[0091] In the above scheme, the top plate 31 is provided with a sliding hole 311. The driven part 44 of the second end 42 of the linkage device 40 can pass through the sliding hole 311 and connect with the barrel 10. The two ends of the sliding hole 311 form a second limiting structure. When the barrel 10 is driven to rotate, it drives the driven part 44 to move along the extension direction of the sliding hole 311. The two ends of the sliding hole 311 can limit the maximum displacement of the second end 42. In this way, the sliding hole 311 can allow the driven part 44 to pass through, playing a role in avoidance, while also limiting the maximum displacement of the second end 42, effectively improving the utilization efficiency of the structural components.

[0092] In one possible implementation, refer to Figure 5 and Figure 6 The grain outlet 11 is located at the bottom of the grain storage chamber. The barrel body 10 also includes a snap-fit ​​part 12, which is located at the grain outlet 11 and fixedly connected to the grain outlet 11. The base 30 is provided with a through hole 312 corresponding to the grain outlet 11. The snap-fit ​​part 12 passes through the through hole 312 and snaps onto the bottom wall of the through hole 312.

[0093] It is understandable that the snap-fit ​​part 12 is located at the edge of the grain outlet 11 and is fixedly connected to the barrel body 10. The snap-fit ​​part 12 passes through the through hole 312 and snaps into the bottom wall of the through hole 312, which can improve the stability of the connection between the barrel body 10 and the base 30.

[0094] In the above scheme, the snap-fit ​​part 12 can be made of the same material as the barrel body 10, or it can be made of other elastic materials, so that the snap-fit ​​part 12 and the bottom wall of the through hole 312 can be easily assembled.

[0095] It is understandable that the snap-fit ​​part 12 can be a ring arranged along the edge of the grain outlet 11, or it can be multiple snap-fit ​​parts arranged at intervals along the grain outlet 11, so as to facilitate the assembly between the snap-fit ​​part 12 and the through hole 312.

[0096] In one possible implementation, the base 30 includes a top plate 31 and a support 32. The top plate 31 is disposed on top of the support 32 and a gap is provided between the top plate 31 and the support 32. A through hole 312 is provided on the top plate 31. The snap-fit ​​part 12 snaps into the bottom wall of the through hole 312 and can move in the gap so that the barrel 10 and the base 30 can rotate relative to each other.

[0097] It is understandable that the barrel 10 and the base 30 are engaged by the snap-fit ​​part 12, which improves the connection stability between the barrel 10 and the base 30 and prevents the barrel 10 from separating from the base 30 during rotation. At the same time, since the base 30 is composed of a top plate 31 and a support base 32, and there is a gap between the top plate 31 and the support base 32, the snap-fit ​​part 12 can both restrict the barrel 10 and the base 30 from separating from each other and have sufficient rotation space in the base 30, which effectively improves the rotation efficiency between the barrel 10 and the base 30.

[0098] In one possible implementation, refer to Figure 4 , Figure 5 , Figure 7 One of the base 30 and the barrel 10 is provided with a rotating device 14, and the other of the base 30 and the barrel 10 is provided with a rotating ring 13. The rotating device 14 abuts against the rotating ring 13. When the barrel 10 is driven to rotate, the rotating device 14 and the rotating ring 13 rotate relative to each other to prevent the barrel 10 and the base 30 from rubbing against each other and causing difficulty in rotation.

[0099] In the above scheme, the barrel 10 and the base 30 are equipped with a rotating device 14 and a rotating ring 13 that cooperate with each other. When the barrel 10 is driven to rotate, the rotating device 14 and the rotating ring 13 rotate relative to each other. In this way, the mutual friction between the barrel 10 and the base 30 during rotation can be reduced, and the rotation efficiency can be improved. At the same time, since the rotating device 14 and the rotating ring 13 abut against each other, a contact force is formed between the rotating device 14 and the rotating ring 13, which can support the barrel 10 and improve the reliability of the connection between the barrel 10 and the base 30.

[0100] In one possible implementation, refer to Figure 7 The rotating device 14 includes a rotating disk 141 and a rolling element 142. The rolling element 142 is movably disposed on the rotating disk 141 and abuts against the rotating ring 13.

[0101] In the above scheme, the rotating disc 141 is a ring structure set on the barrel 10 or the base 30, and the rotating ring 13 is set on the outer periphery of the grain outlet 11, or even at the edge of the barrel 10 and the base 30.

[0102] The rolling element 142 can be, but is not limited to, a roller, a ball, etc., and the rolling element 142 can also be made of, but is not limited to, rubber, plastic, wood, or metal.

[0103] It is understandable that the rolling element 142 is movably placed on the rotating disk 141, and the rotating disk 141 can limit the rolling element 142 to prevent it from rolling down randomly.

[0104] It is understandable that the rolling element 142 abuts against the rotating ring 13 and is movably placed on the rotating disk 141, so that when the barrel 10 is driven to rotate, the rolling element 142 can rotate under force, which reduces the frictional resistance between the rotating disk 141 and the rotating ring 13 and improves the rotation efficiency.

[0105] In one possible implementation, each rotating disk 141 is provided with a receiving hole 143, and the rolling element 142 is disposed in the receiving hole 143 and protrudes from both ends of the receiving hole 143.

[0106] In the above scheme, the rolling element 142 is disposed in the receiving hole 143 and protrudes from both ends of the receiving hole 143, and the receiving hole 143 can limit the movement of the rolling element 142. The fact that the rolling element 142 protrudes from both ends of the receiving hole 143 allows it to both roll relative to the barrel 10 and rotate relative to the base 30, significantly improving rotation efficiency.

[0107] In one possible implementation, refer to Figure 7 The rotating device 14 also includes a third limiting structure 145. The rotating disk 141 is provided in the third limiting structure 145 and can rotate relative to the third limiting structure 145.

[0108] In the above scheme, the third limiting structure 145 can be a protrusion on the base 30 or the barrel 10. The protrusion is arranged in a ring shape with a limiting groove in the middle, and the rotating disk 141 is placed in the limiting groove. The protrusion can also be a series of protruding pillars arranged at intervals, with multiple protruding pillars facing each other to limit the rotating disk 141. The third limiting structure 145 can also be a groove on the base 30 or the barrel 10. The groove limits the rotating disk 141 to prevent it from shifting due to force during the rotation of the barrel 10, thus preventing it from cooperating with the rotating ring 13.

[0109] In one possible implementation, refer to Figure 7 The bottom wall of the limiting structure is also provided with a rotating guide rail 144, and one end of the rolling element 142 contacts the rotating guide rail 144 and can roll along the rotating guide rail 144.

[0110] In the above scheme, the bottom wall of the limiting structure is also provided with a rotating guide rail 144. The rotating guide rail 144 consists of two parallel convex rails. One end of the rolling element 142 contacts the rotating guide rail 144, which can reduce the contact area between the rolling element 142 and the base 30 or the barrel 10, reduce the friction when the rolling element 142 rotates with the base 30 or the barrel 10, and improve the rotation efficiency.

[0111] In one possible implementation, the rotating ring 13 has a rolling groove that engages with the rolling element 142, and when the barrel 10 is driven to rotate, the other end of the rolling element 142 rolls along the rolling groove.

[0112] In the above scheme, the rotating groove on the rotating ring 13 abuts against one end of the rolling element 142, so that when the barrel 10 is driven to rotate, the rolling element 142 can roll along the rotating groove, preventing the rotating ring 13 and the rotating device 14 from slipping and misaligning.

[0113] In one possible implementation, the base 30 also includes a rice-dispensing cavity 321, which is connected to the grain outlet 11 to receive the grain flowing out of the grain outlet 11. When dispensing rice, the user can place the container holding the grain in the rice-dispensing cavity 321. Since the rice-dispensing cavity 321 is connected to the grain outlet 11, when the bucket 10 is driven to open the grain outlet 11 by the linkage device 40, the grain in the grain storage cavity can flow directly into the container, making the operation simple and convenient.
