Description

Technical Field

[0001] The present application relates to a storage container, and in particular to an anti-misoperation structure and a rotary grain discharging device. Background Art

[0002] A household rice bucket generally refers to a container for storing and taking out grains. The rice bucket has a large grain storage capacity. During the use of the rice bucket, users usually need to take out the required amount of rice from the rice bucket two to three times a day. To prevent users from directly taking rice in the rice bucket, a rice dropping port for rice to fall is provided on the rice bucket. The rice drops from the rice bucket under the action of pressure. However, since the pressure of the rice in the rice bucket changes with the amount of rice in the rice bucket, when the amount of rice in the rice bucket is large, the rice dropping speed is fast, and when the amount of rice in the rice bucket is small, the rice dropping speed is slow, making it difficult to obtain a stable amount of dropped rice.

[0003] To solve the above technical problems, a rotary grain discharging device is specially designed. The rotary grain discharging device realizes quantitative grain taking through rotary motion, and the taken grains generally fall into a grain receiving drawer. However, in the prior art, even when there is no grain receiving drawer in the grain receiving bin, in the case of misoperation, the rotary grain discharging device can still rotate to discharge grains, resulting in the grains directly falling into the grain receiving bin, forming unnecessary waste. Even if this part of the grains can be reused, it is still a difficult thing to take them out. Summary of the Invention

[0004] The present application mainly solves the technical problem existing in the prior art that when there is no grain receiving drawer in the grain receiving bin, the rotary grain discharging device can still rotate to discharge grains, resulting in the grains directly falling into the grain receiving bin, forming unnecessary waste. The present application provides an anti-misoperation structure and a rotary grain discharging device in which when there is no grain receiving drawer in the grain receiving bin, the rotary device is locked by a locking plate to prevent the discharged grains from directly falling into the grain receiving bin.

[0005] To solve the above technical problems and achieve the above application objectives, on the one hand, the present application provides an anti-misoperation structure, which is characterized in that it includes a main body, a locking plate and a rotating device for quantitatively taking grains. The rotating device includes a rotating body and a transmission rod. The rotating body is connected to the transmission rod. A locking hole is provided in the locking plate. The locking plate is sleeved outside the transmission rod through the locking hole. The locking hole includes a second position and a first position arranged in sequence along a first direction. The first position is used to lock the transmission rod, and the second position is used to unlock the transmission rod. A grain receiving bin is provided in the main body, and a grain receiving drawer is slidably arranged in the grain receiving bin. A lifting device is arranged between the grain receiving bin and the locking plate. The lifting device is used to drive the locking plate to move along the first direction. The locking plate includes a first state and a second state. When the locking plate is in the first state, the grain receiving drawer is separated from the locking plate, and the transmission rod is located in the first position; when the locking plate is in the second state, the grain receiving drawer is in contact with the locking plate, and the transmission rod is located in the second position.

[0006] Among them, the locking hole includes a wide hole for accommodating the second position and a narrow hole for accommodating the first position. The narrow hole is communicated with the wide hole. A locking plane is provided on the transmission rod and abuts against the narrow hole. When the transmission rod is in the narrow hole, the transmission rod abuts against the narrow hole through the locking plane, and the transmission rod is locked in the narrow hole; when the transmission rod is in the wide hole, the locking rod can rotate freely in the wide hole.

[0007] Among them, a rotating hole is provided in the main body along the first direction, and a lifting device is rotatably connected in the rotating hole. An intermediate shaft is provided on the main body. The lifting device includes a rotating sleeve, a first rotating plate and a second rotating plate. The first rotating plate and the second rotating plate are fixedly connected to the rotating sleeve. A certain rotation angle is formed between the first rotating plate and the second rotating plate. The rotating sleeve is sleeved outside the intermediate shaft and is rotatably connected to the intermediate shaft. An abutting plate is provided on one side of the locking plate close to the lifting device. When the locking plate is in the second state, the first rotating plate abuts against the abutting plate, and the second rotating plate abuts against the grain receiving drawer; during the process of the locking plate being converted from the first state to the second state, the first rotating plate rotates towards the abutting plate side to drive the locking plate to move along the first direction, and the transmission rod enters the second position from the first position.

[0008] Among them, an abutting portion that can abut against the second rotating plate is provided on the grain receiving drawer.

[0009] Further included is a telescopic rod for locking the grain receiving drawer when the locking plate is in the second state. The rotating device is connected to the telescopic rod through a motion conversion device. The motion conversion device is used to convert the circumferential rotational motion of the rotating device into the linear motion of the telescopic rod. A locking hole corresponding to the telescopic rod is provided on the grain receiving drawer. When the rotating device rotates, it includes a fourth state for delivering grain and a third state for receiving grain. When the rotating device is in the fourth state, the telescopic rod is located within the locking hole to prevent the grain receiving drawer from moving, and the locking plate is in the second state. When the rotating device is in the third state, the telescopic rod is located outside the locking hole, enabling the grain receiving drawer to move, and the locking plate is in the first state.

[0010] Wherein, the motion conversion device includes a rotating disk that rotates synchronously with the rotating device. An arc-shaped groove is eccentrically provided on the rotating disk. The arc-shaped groove includes a first end and a second end. The distance from the arc-shaped groove to the center of the rotating disk gradually increases from the first end to the second end. A connecting rod is provided at the first end of the telescopic rod close to the rotating disk. The telescopic rod is slidably connected to the arc-shaped groove through the connecting rod. Under the rotation of the rotating disk, the telescopic rod expands and contracts vertically.

[0011] Wherein, when the connecting rod is close to the first end of the arc-shaped groove, the telescopic rod is located outside the locking hole. When the connecting rod is close to the second end of the arc-shaped groove, the telescopic rod is located within the locking hole. A positioning block is provided on the locking hole in the telescopic direction of the telescopic rod. A positioning hole corresponding to the locking hole is provided within the positioning block. The telescopic rod is located within the locking hole during the vertical expansion and contraction process.

[0012] On the other hand, the present application provides a rotating grain discharging device, including the anti-misoperation structure in Embodiment 1. It is characterized in that it includes a storage grain bin and a grain transferring device provided within a housing body. A rotating device is further provided on the housing body. The rotating device is connected to the grain transferring device through an intermediate transmission device. The grain transferring device includes a grain receiving state corresponding to the third state and a grain delivering state corresponding to the fourth state. In the grain receiving state, the grain transferring device is docked with the storage grain bin for quantitatively receiving the grain in the storage grain bin. The telescopic rod is located outside the locking hole, the grain receiving drawer is separated from the locking plate, and the transmission rod is located within the first position. In the grain delivering state, the grain transferring device is docked with the grain receiving bin and is used to transfer the quantitatively received grain in the storage grain bin to the grain receiving bin, and the telescopic rod is located within the locking hole. The grain receiving drawer is in contact with the locking plate, and the transmission rod is located within the second position. The rotation of the grain transferring device is used to switch between the grain transferring state and the grain receiving state back and forth.

[0013] Among them, a main body for accommodating the grain receiving bin is arranged inside the outer shell, and a positioning block is arranged on the main body.

[0014] Among them, a locking hole, a positioning hole and a telescopic rod are sequentially arranged in the outer shell from bottom to top in a first direction, and the first direction coincides with the telescopic direction of the telescopic rod.

[0015] Compared with the prior art, the anti-misoperation structure and the rotary grain discharging device of the present application have the following beneficial effects:

[0016] By rotating the rotating device, the rotating device forms a rotational motion and forms a rotational motion of the grain transferring device through the motion transmission device. The grain transferring device includes a grain receiving state corresponding to the third state and a grain feeding state corresponding to the fourth state. In the grain receiving state, the grain transferring device is docked with the storage granary, and the grain in the storage granary gradually leaks into the grain transferring device until the grain transferring device is saturated. And under the drive of the rotating device, the telescopic rod moves out of the locking hole, unlocking the grain receiving drawer, and then the grain receiving drawer is moved out of the grain receiving bin. The locking plate moves in the opposite direction of the first direction, and the transmission rod enters the first position from the second position. The transmission rod is locked by the first position, avoiding the rotation of the rotating device when there is no grain receiving drawer in the grain receiving bin; in the grain feeding state, the grain receiving drawer enters the grain receiving bin, the locking plate moves along the first direction, the transmission rod enters the second position from the first position, and the transmission rod is unlocked by the second position, so that the rotating device can rotate freely. At this time, the grain receiving device is docked with the grain receiving bin and is used to transfer the grain received in the storage granary into the grain receiving drawer. And under the drive of the rotating device, the telescopic rod enters the locking hole, completing the locking of the grain receiving drawer. The rotational motion of the rotating device can not only complete the quantitative transfer of the grain but also complete the locking and unlocking of the grain receiving drawer. The sliding of the grain receiving drawer can lock and unlock the transmission rod. And when the rotating device needs to rotate, the grain receiving drawer must be in the grain receiving bin. When the grain receiving drawer needs to be moved out of the grain receiving bin, it is necessary to unlock the grain receiving drawer and after unlocking, the transmission rod enters the first position from the second position. The transmission rod is locked by the first position, so that the rotating device will not form a misoperation after the grain receiving drawer is moved out of the grain receiving bin, thus deeply binding the relationship between the locking of the transmission rod and the locking of the grain receiving drawer, so as to ensure that the grain receiving drawer can only receive the grain from the grain transferring device in the grain feeding state, ensuring that the grain will not be wasted, so as to optimize the overall structure of the overall rotary grain discharging device.

[0017] Therefore, the present application has the characteristics of reasonable structure and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] To make the objectives, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0039] In the prior art, there is a technical problem that when there is no grain receiving drawer 8 in the grain receiving bin 7, the rotating grain discharging device can still rotate to discharge grain, resulting in unnecessary waste of grain directly falling into the grain receiving bin 7.

[0040] To this end, the present application provides an anti-misoperation structure on the one hand, including a main body 1, a locking plate 2, and a rotating device 30 for quantitatively taking grain. The rotating device 30 includes a rotating body 3 and a transmission rod 4. The rotating body 3 is connected to the transmission rod 4. A locking hole is provided in the locking plate 2. The locking plate 2 is sleeved outside the transmission rod 4 through the locking hole. The locking hole includes a second position 6 and a first position 5 arranged in sequence along a first direction. The first position 5 is used to lock the transmission rod 4, and the second position 6 is used to unlock the transmission rod 4. A grain receiving bin 7 is provided in the main body 1. A grain receiving drawer 8 is slidably arranged in the grain receiving bin 7. A lifting device 47 is arranged between the grain receiving bin 7 and the locking plate 2. The lifting device 47 is used to drive the locking plate 2 to move along the first direction. The locking plate 2 includes a first state and a second state. In the first state of the locking plate 2, the grain receiving drawer 8 is separated from the locking plate 2, and the transmission rod 4 is located in the first position 5; in the second state of the locking plate 2, the grain receiving drawer 8 is in contact with the locking plate 2, and the transmission rod 4 is located in the second position 6.

[0041] In addition, on the other hand, the present application provides a rotating grain discharging device, including the anti-misoperation structure in Embodiment 1, including a grain storage bin 28 and a grain transferring device 29 arranged in a housing 27. A rotating device 30 is further arranged on the housing 27. The rotating device 30 is connected to the grain transferring device 29 through an intermediate transmission device 31. The grain transferring device 29 includes a grain receiving state corresponding to a third state and a grain sending state corresponding to a fourth state. In the grain receiving state, the grain transferring device 29 is docked with the grain storage bin 28 for quantitatively receiving the grain in the grain storage bin 28. The telescopic rod 17 is located outside the locking hole 19. The grain receiving drawer 8 is separated from the locking plate 2, and the transmission rod 4 is located in the first position 5; in the grain sending state, the grain transferring device 29 is docked with the grain receiving bin 7 and is used to transfer the quantitatively received grain in the grain storage bin 28 into the grain receiving bin 7 and the telescopic rod 17 is located in the locking hole 19. The grain receiving drawer 8 is in contact with the locking plate 2, and the transmission rod 4 is located in the second position 6; the rotation of the grain transferring device 29 is used to switch the grain transferring state and the grain receiving state back and forth.

[0042] Embodiment 1:

[0043] Figures 1 to 14 An embodiment of the anti-misoperation device of the present application is shown.

[0044] Please refer to Figure 1, Embodiment 1 of the present application discloses an anti-misoperation device, which is arranged based on a rotary grain discharging device. When there is no grain receiving drawer 8 in the grain receiving bin 7 of the rotary grain discharging device, the transmission rod 4 of the rotary device 30 is locked by the anti-misoperation device to prevent the grain transfer device 29 from directly transferring grains into the grain receiving bin 7 without a grain receiving drawer 8 due to misoperation of the rotary device 30, thus avoiding waste of grains. And only when there is a grain receiving drawer 8 in the grain receiving bin 7, the grain receiving drawer 8 drives the locking plate 2 to move along the first direction through the lifting device 47. When the transmission rod 4 is at the second position 6 in the locking hole, the locking plate 2 unlocks the transmission rod 4, so as to determine whether the locking plate 2 locks the transmission rod 4 with the presence or absence of a grain receiving drawer 8 in the grain receiving bin 7 as the triggering condition.

[0045] In Embodiment 1 of the present application, the rotary device 30 is a triggering device for the rotary grain discharging device to discharge grains. The grain receiving state and the grain sending state are switched by the rotation of the rotary device 30. The rotary device 30 includes a rotary body 3 and a transmission rod 4. The rotary body 3 is connected to the transmission rod 4. Under the rotation of the rotary body 3, the transmission rod 4 rotates synchronously. Therefore, as long as the transmission rod 4 is locked, the anti-misoperation function can be realized.

[0046] Among them, the transmission rod 4 is more specifically locked by the locking plate 2, and the triggering condition for anti-misoperation is to judge whether there is a grain receiving drawer 8 in the grain receiving bin 7.

[0047] Please refer to Figure 2 , in Embodiment 1 of the present application, a locking hole is longitudinally arranged in the locking plate 2. The transmission rod 4 extends toward the locking plate 2 and passes through the locking hole to extend to the other side of the locking plate 2, so as to form a use environment where the locking plate 2 is sleeved outside the transmission rod 4 through the locking hole.

[0048] Please refer to Figure 9 and Figure 10 , in Embodiment 1 of the present application, it includes a second position 6 and a first position 5 arranged in sequence along the first direction. The establishment of the second position 6 and the first position 5 is for locking or unlocking the transmission rod 4. The second position 6 refers to the position of the transmission rod 4 in the locking hole in the locked state, and the first position 5 refers to the position of the transmission rod 4 in the locking hole in the unlocked state. Therefore, the first position 5 is used to lock the transmission rod 4, and the second position 6 is used to unlock the transmission rod 4.

[0049] Among them, in Embodiment 1 of the present application, the second position 6 is specifically reflected by a wide hole, and the first position 5 is specifically reflected by a narrow hole. The locking hole includes a wide hole and a narrow hole, and the wide hole and the narrow hole are communicated, so that the transmission rod 4 can shuttle up and down in the locking hole. The basis for defining the wide hole and the narrow hole is the transverse width of the hole. The transverse distance of the wide hole is greater than the transverse distance of the narrow hole.

[0050] In the preferred state, the locking hole is composed of two intersecting kidney-shaped holes, that is, both the wide hole and the narrow hole are kidney-shaped holes, and the center lines of the wide hole and the narrow hole are collinearly arranged.

[0051] Among them, please refer to Figure 11 and Figure 12 In Embodiment 1 of the present application, a locking plane 9 that abuts against the narrow hole is provided on the transmission rod 4. After the locking plane 9 is provided, the lateral distance at the locking plane 9 is smaller than the maximum lateral distance of the transmission rod 4, and the transmission rod 4 at the locking plane 9 and the narrow hole are in clearance fit. The lateral distance of the transmission rod 4 where the locking plane 9 is not provided is greater than the lateral distance of the narrow hole. Therefore, when entering the narrow hole, only the narrower part with the locking plane 9 aligned with the narrow hole can enter. And once entering the locking hole, the transmission rod 4 cannot rotate because the locking plane 9 abuts against the narrow hole. The transmission rod 4 can only exit the narrow hole in the reverse direction of the entering orientation. The lateral distance of the wide hole is greater than the maximum lateral distance of the transmission rod 4. Therefore, the transmission rod 4 can rotate freely in the wide hole after entering the wide hole.

[0052] Among them, the transmission rod 4 can be a cylindrical transmission rod 4 or a quadrangular prism transmission rod 4. When the transmission rod 4 is a cylindrical transmission rod 4, the maximum lateral distance of the transmission rod 4 is the diameter of the transmission rod 4; when the transmission rod 4 is a quadrangular prism, the maximum lateral distance of the transmission rod 4 is the length of the cross-section of the transmission rod 4.

[0053] In the preferred state, the locking plane 9 is symmetrically arranged left and right along the center line of the transmission rod 4, forming constraints on the transmission rod 4 in two directions. Among them, the locking plane 9 is formed by radially cutting a rectangular groove.

[0054] Please refer to Figure 1 and Figure 5 In Embodiment 1 of the present application, the trigger condition for whether the transmission rod 4 is locked is whether there is a grain receiving drawer 8 in the grain receiving bin 7. If there is a grain receiving drawer 8 in the grain receiving bin 7, the rotating device 30 can rotate with confidence because no matter how it rotates, the grain in the grain transferring device 29 will always fall into the grain receiving drawer 8, without causing waste of grain; if there is no grain receiving drawer 8 in the grain receiving bin 7, the rotating device 30 needs to be locked to prevent the grain in the grain transferring device 29 from directly falling into the grain receiving bin 7 due to accidental touch.

[0055] In Embodiment 1 of the present application, the main body 1 serves as a box for storing the grain receiving drawer 8, with an opening provided at one end to enable the entry and exit of the grain receiving drawer 8. A lifting device 47 is provided between the grain receiving bin 7 and the locking plate 2. The lifting device 47 is used to drive the locking plate 2 to move in a first direction. The locking plate 2 includes a first state and a second state. When the locking plate 2 is in the first state, the grain receiving drawer 8 is separated from the locking plate 2. When the locking plate 2 is in the second state, the grain receiving drawer 8 is in contact with the locking plate 2. The transmission rod 4 is located within the second position 6. The contact between the lifting device 47 and the locking plate 2 can drive the locking plate 2 to move in the first direction, while the transmission rod 4 remains stationary. Therefore, the transmission rod 4 can enter the second position 6 from the first position 5. We also define the movement direction of the locking plate 2 when the transmission rod 4 enters the second position 6 from the first position 5 as the first direction.

[0056] Among them, the lifting device 47 realizes the movement of the locking plate 2 by rotation. The main body 1 is provided with a rotation hole 10 along the first direction, so that the rotation hole 10, the lifting device 47, and the locking plate 2 are arranged from bottom to top along the first direction. The lifting device 47 is rotatably connected within the rotation hole 10. An intermediate shaft 11 is provided on the column body, and the lifting device 47 is rotatably connected around the intermediate shaft 11. Specifically, the rotation connection method is achieved by providing a rotation sleeve 12. The rotation sleeve 12 is a part of the lifting device 47. The lifting device 47 further includes a first rotating plate 13 and a second rotating plate 14. The first rotating plate 13 and the second rotating plate 14 are fixedly connected to the rotation sleeve 12. There is a certain rotation angle between the first rotating plate 13 and the second rotating plate 14. The rotation sleeve 12 is sleeved outside the intermediate shaft 11 and is rotatably connected to the intermediate shaft 11. A contact plate 15 is provided on the side of the locking plate 2 close to the lifting device 47. The contact plate 15 forms a certain angle with the locking plate 2. In a preferred state, the locking plate 2 is perpendicular to the contact plate 15.

[0057] Please refer to Figures 1 to 4 , when the grain receiving drawer 8 enters the grain receiving bin 7, the second rotating plate 14 gradually abuts against the grain receiving drawer 8 and drives the first rotating plate 13 to rotate towards the locking plate 2 side, so as to drive the locking plate 2 to move in the first direction. The transmission rod 4 enters the second position 6 from the first position 5, forming the unlocking of the rotating device 30.

[0058] Please refer to Figures 5 to 8 , when the grain receiving drawer 8 is pulled out of the grain receiving bin 7, the second rotating plate 14 disengages from the grain receiving drawer 8 and drives the first rotating plate 13 to rotate towards the grain receiving bin 7 side. The locking plate 2 loses the supporting force, and the locking plate 2 moves in the opposite direction of the first direction. The transmission rod 4 enters the first position 5 from the second position 6, forming the locking of the rotating device 30.

[0059] Among them, in Embodiment 1 of the present application, the grain receiving drawer 8 is provided with a contact portion 16 that can abut against the second rotating plate 14.

[0060] However, when the grain receiving drawer 8 is pulled out of the grain receiving bin 7, it is necessary to ensure that the narrower part of the transmission rod 4 provided with the locking plane 9 is aligned with the narrow hole to smoothly enter the narrow hole. If the wider part of the transmission rod 4 is aligned with the narrow hole, then after the grain receiving drawer 8 is pulled out, the transmission rod 4 cannot enter the narrow hole to achieve the locking of the transmission rod 4. Therefore, every time the grain receiving drawer 8 is pulled out, ensuring that the transmission rod 4 is rotated to the correct position is also a necessary factor. So during operation, it will seem rather troublesome, but it does not affect the final presented effect.

[0061] Therefore, it is particularly important to ensure the position of the transmission rod 4 before the grain receiving drawer 8 is pulled out.

[0062] To this end, in Embodiment 1 of the present application, it further includes a telescopic rod 17 for locking the grain receiving drawer 8 when the locking plate 2 is in the second state. The rotating device 30 is connected to the telescopic rod 17 through a motion conversion device. The motion conversion device is used to convert the circumferential rotational motion of the rotating device 30 into the linear motion of the telescopic rod 17. A locking hole 19 corresponding to the telescopic rod 17 is provided on the grain receiving drawer 8. The locking and unlocking of the grain receiving drawer 8 are achieved through the cooperation with the telescopic rod 17. When the rotating device 30 rotates, it includes a fourth state corresponding to the grain feeding state and a third state corresponding to the grain receiving state.

[0063] Please refer to Figures 1 to 4 As shown, when the rotating device 30 is in the fourth state, the telescopic rod 17 is located within the locking hole 19, completing the locking of the grain receiving drawer 8 to prevent the grain receiving drawer 8 from moving. And at this time, the transmission rod 4 is in the second state, the wider part of the transmission rod 4 is aligned with the narrow hole, and the transmission rod 4 is within the wide hole. The rotating device 30 can rotate freely, and the grain transfer device 29 can transfer the quantitatively received grain into the grain receiving drawer 8. Due to the existence of the telescopic rod 17, the grain receiving drawer 8 cannot move.

[0064] Please refer to Figures 5 to 8 As shown, when the rotating device 30 is in the third state, the telescopic rod 17 is located outside the locking hole 19, completing the unlocking of the grain receiving drawer 8. And at this time, the locking plate 2 is in the second state, the narrower part of the transmission rod 4 is aligned with the narrow hole. When the grain receiving drawer 8 is pulled out, the transmission rod 4 will automatically fall into the narrow hole. Therefore, only when the grain receiving drawer 8 is in the unlocked state, that is, the third state of the rotating device 30, can the grain receiving drawer 8 be pulled out of the grain receiving bin 7. And when the rotating device 30 is in the third state, the narrower part of the transmission rod 4 just aligns with the narrow hole, thus deeply binding the relationship between the locking of the transmission rod 4 and the locking of the grain receiving drawer 8, so as to ensure that the grain can only be received from the grain transfer device 29 in the grain feeding state, ensuring that the grain is not wasted, and optimizing the overall structure of the overall rotating grain discharging device.

[0065] Please refer to Figure 13 and Figure 14As shown in the figure, in Embodiment 1 of the present application, the motion conversion device includes a rotating disk 20 that rotates synchronously with the rotating device 30. An arc-shaped groove 21 is eccentrically provided on the rotating disk 20. The arc-shaped groove 21 includes a first end 22 and a second end 23. The distance from the arc-shaped groove 21 to the circle of the rotating disk 20 is gradually increased from the first end 22 to the second end 23. One end of the telescopic rod 17 close to the rotating disk 20 is provided with a connecting rod 24. The telescopic rod 17 is slidably connected to the arc-shaped groove 21 through the connecting rod 24. Under the rotation of the rotating disk 20, the telescopic rod 17 is telescopically arranged up and down.

[0066] Among them, the rotating disk 20 is a disk-like structure. The eccentric setting of the rotating disk 20 and the arc-shaped groove 21 means that the center of the rotating disk 20 is not concentric with the center of the arc-shaped groove 21, so as to ensure that the arc-shaped groove 21 rotates eccentrically when the rotating disk 20 rotates, thereby adjusting the distance between the arc-shaped groove 21 and the locking hole 19, and thus realizing the up and down telescoping of the telescopic rod 17.

[0067] Among them, the central angle of the arc-shaped groove 21 is 60° to 80°, and both the first end 22 and the second end 23 of the arc-shaped groove 21 are provided with rounded corners. The connecting rod 24 is a cylindrical structure. The height of the connecting rod 24 is greater than the thickness of the arc-shaped groove 21 to ensure that the connecting rod 24 always slides within the arc-shaped groove 21. The connecting rod 24 and the arc-shaped groove 21 are in clearance fit. The other end of the connecting rod 24 connected to the telescopic rod 17 is provided with a limiting ring to ensure that the connecting rod 24 and the arc-shaped groove 217 will not be separated.

[0068] Among them, the telescopic rod 17 is a cuboid structure. The axis of the connecting rod 24 is perpendicular to the telescopic rod 17. Both ends of the telescopic rod are provided with chamfers. The telescopic rod 17 and the locking hole 19 are in clearance fit.

[0069] In Embodiment 1 of the present application, when the rotating device 30 rotates, it includes a fourth state for feeding grain and a third state for receiving grain.

[0070] Among them, as Figures 5 to 8Shown is the third state of the rotating device 30. When the rotating device 30 is rotated counterclockwise, the rotating disk 20 rotates along with the rotating device 30. At the same time, the connecting rod 24 moves from the second end 23 to the first end 22 within the arc-shaped groove 21. Since the distance from the arc-shaped groove 21 to the center of the rotating disk 20 gradually increases from the first end 22 to the second end 23, during the rotation process, the arc-shaped groove 21 acts as a driving member to drive the telescopic rod 17 to contract inward until the connecting rod 24 abuts against the side wall of the first end 22 of the arc-shaped groove 21. At this time, the rotating disk 20 stops rotating and the telescopic rod 17 is located outside the positioning hole 26, enabling the telescopic rod 17 to complete the unlocking action for the grain receiving drawer 8 to ensure that the grain receiving drawer 8 can move freely. Since the entire rotating grain discharging device is in the grain receiving state at this time, the grain receiving device in the rotating grain discharging device is used to quantitatively receive the grain from the storage granary 28 and will not leak the grain into the grain receiving drawer 8. Therefore, the grain receiving drawer 8 can be moved without being locked. Thus, if the grain receiving drawer 8 is directly pulled out of the grain receiving bin 7, the lifting device 47 will lose support, and the transmission rod 4 will enter the first position 5 from the second position 6 to form a lock on the rotating device 30.

[0071] Among them, as Figures 1 to 4 Shown is the fourth state of the rotating device 30. When the rotating device 30 is rotated clockwise, the rotating disk 20 rotates along with the rotating device 30. At the same time, the connecting rod 24 rotates from the first end 22 to the second end 23 within the arc-shaped groove 21. Since the distance from the arc-shaped groove 21 to the rotating disk 20 gradually increases from the first end 22 to the second end 23, during the rotation process, the arc-shaped groove 21 acts as a driving member to drive the telescopic rod 17 to extend outward until the connecting rod 24 abuts against the side wall of the second end 23 of the arc-shaped groove 21. At this time, the rotating disk 20 stops rotating and the telescopic rod 17 is located within the positioning hole 26, enabling the telescopic rod 17 to complete the locking action for the grain receiving drawer to ensure that the grain receiving drawer 8 cannot move. Since the entire rotating grain discharging device is in the grain feeding state at this time, the grain receiving device in the rotating grain discharging device is used to transfer the quantitatively received grain in the storage granary 28 to the grain receiving drawer 8. Therefore, if the grain receiving drawer 8 can move at this time, the grain will overflow to other places, resulting in unnecessary waste of grain. So, it is necessary to lock the grain receiving drawer 8 to prevent it from moving. Therefore, the grain receiving drawer 8 will always be ensured to be within the grain receiving bin 7. The lifting device 47 abuts against the grain receiving drawer 8 to drive the grain receiving drawer 8 to move in the first direction, and the transmission rod 4 enters the second position 6 from the first position 5 to form an unlocking of the rotating device 30.

[0072] In Embodiment 1 of the present application, a positioning block 25 is provided in the telescopic direction of the telescopic rod 17. A positioning hole 26 corresponding to the locking hole 19 is provided in the positioning block 25. The telescopic rod 17 is located within the locking hole 19 during the up-and-down telescopic process, so as to ensure that the rotating disk 20 will not rotate around the transmission rod 4 under the rotation of the rotating disk 20, and to ensure that the telescopic direction of the telescopic rod 17 is perpendicular to the positioning block 25 to ensure the up-and-down floating of the telescopic rod 17.

[0073] In an embodiment of the present application, the rotating device 30 includes a rotating body 3 and a transmission rod 4. The rotating body 3 and the rotating rod are both cylindrical structures arranged coaxially. The rotating body is connected to the transmission rod 4. Under the rotation of the rotating body, the transmission rod 4 rotates synchronously. The rotating disk 20 is connected to the transmission rod 4 through a transition member 48. An interference fit is provided between the transition member 48 and the rotating disk 20. A prism is provided on the transmission rod 4. The central axis of the prism is arranged coaxially with the transmission rod 4. A multi-sided hole matching the prism is provided at the center of the transition member 48. Therefore, under the rotation of the transmission rod 4, the transition member 48 can be driven to rotate, and the transition member 48 further drives the rotating disk 20 to rotate. Among them, the transition member 48 is a disk-shaped part.

[0074] Embodiment 2:

[0075] Figures 15 to 19 An embodiment of the rotating grain discharging device of the present application is shown.

[0076] Reference Figure 15 and Figure 16 A rotating grain discharging device is disclosed, which includes a grain bin arranged in a housing 27, a grain transferring device 29 and a main body 1. A grain receiving bin 7 is arranged in the main body 1. Among them, the storage grain bin 28 is used for storing grains, and the grain receiving bin 7 is used for quantitatively receiving grains from the storage grain bin 28. The storage grain bin 28 and the grain receiving bin 7 are connected through the grain transferring device 29. The grain transferring device 29 transports a preset volume of grains from the storage grain bin 28 to the grain receiving bin 7 through its own rotational movement.

[0077] Such as Figure 16As shown, in the grain receiving state, the grain transfer device 29 is docked with the grain storage bin 28 and is used to quantitatively receive the grain in the grain storage bin 28. The grain receiving state of the grain transfer device 29 corresponds to the third state of the rotating device 30, that is, when the rotating device 30 belongs to the third state, the grain transfer device 29 is in the grain receiving state. The grain receiving state of the grain transfer device 29 corresponds to the first state of the locking plate 2, that is, when the locking plate 2 belongs to the first state, the grain transfer device 29 is in the grain receiving state. When the rotating device 30 is rotated counterclockwise, the rotating disk 20 rotates along with the rotating device 30, and at the same time, the connecting rod 24 moves from the second end 23 to the first end 22 in the arc groove 21. Since the distance from the arc groove 21 to the center of the rotating disk 20 is gradually increased from the first end 22 to the second end 23, the arc groove 21 acts as a driving member to drive the telescopic rod 17 to retract inward during the rotation process until the connecting rod 24 and the first end 22 of the arc groove 21 are aligned. When the grain receiving drawer 8 is pulled out, the transmission rod 4 will automatically fall into the narrow hole, thereby locking the entire rotating device 30. Since the entire rotating grain discharging device is in a grain receiving state at this time, the grain receiving device in the rotating grain discharging device in this state is used to quantitatively receive the grain from the grain storage bin 28, and will not leak the grain into the grain receiving drawer 8. Therefore, the grain receiving drawer 8 can be moved without being locked. Moreover, after the grain receiving drawer 8 is pulled out of the grain receiving bin 7, if the rotating device 30 is rotated at will due to accidental touch or the like, the grain will directly fall into the grain receiving bin 7, so the rotating device 30 cannot be rotated.

[0078] like Figure 15As shown, in the grain delivery state, the grain transfer device 29 is docked with the grain receiving bin 7 and is used to transfer the quantitatively received grain in the storage bin 28 into the grain receiving bin 7. The rotation of the grain transfer device 29 is used to switch between the grain receiving state and the grain delivery state back and forth. The grain delivery state of the grain transfer device 29 corresponds to the first state of the rotating device 30. When the rotating device 30 is rotated clockwise, the rotating disk 20 rotates along with the rotating device 30. At the same time, the connecting rod 24 rotates from the first end 22 to the second end 23 in the arc-shaped groove 21. Since the distance from the arc-shaped groove 21 to the rotating disk 20 is gradually increased from the first end 22 to the second end 23, during the rotation process, the arc-shaped groove 21 acts as a driving member to drive the telescopic rod 17 to extend outwards until the connecting rod 24 abuts against the side wall of the second end 23 of the arc-shaped groove 21. At this time, the rotating disk 20 stops rotating and the telescopic rod 17 is located in the positioning hole 26 at this time, so that the telescopic rod 17 completes the locking action on the grain receiving drawer 8 to ensure that the grain receiving drawer 8 cannot move. And due to the existence of the grain receiving drawer 8, the grain receiving drawer 8 drives the locking plate 2 to move in the first direction through the lifting device 47. At this time, the transmission rod 4 enters the second position 6 from the first position 5, completing the unlocking of the rotating device 30. Since the grain receiving drawer 8 is provided in the grain receiving bin 7, no matter how the grain receiving device rotates, the grain will always fall into the grain receiving bin 7, and the entire grain discharging device by rotation is in the grain delivery state. In this state, the grain receiving device in the grain discharging device by rotation is used to rotate the quantitatively received grain in the storage bin 28 into the grain receiving drawer 8. Therefore, if the grain receiving drawer 8 can move at this time, the grain will overflow to other places, resulting in unnecessary waste of grain. So it is necessary to lock the grain receiving drawer 8 to prevent it from moving.

[0079] In Embodiment 2 of the present application, a positioning block 25 is provided in the telescopic direction of the telescopic rod 17. A positioning hole 26 corresponding to the locking hole 19 is provided in the positioning block 25. The telescopic rod 17 is located in the locking hole 19 during the up and down telescopic process, so as to ensure that the rotating disk 20 will not rotate around the transmission rod 4 under the rotation of the rotating disk 20, and ensure that the telescopic direction of the telescopic rod 17 is perpendicular to the positioning block 25 to ensure the up and down floating of the telescopic rod 17.

[0080] In the application, a twisting storage device is used for storing and quantitatively taking out grains. Specifically, the grains in this application can be any kind of granular materials with similar shapes, such as rice, wheat, nuts, corn kernels, etc. The granary provided in Embodiment 2 stores grains through the storage granary 28. The storage granary 28 has the characteristic of good airtightness, so as to ensure the dryness of grains for a long time, which is beneficial to the storage of grains. The outer shell 27 can be a rectangular outer shell, made of plastic, alloy or other engineering materials. The outer shell 27 and the storage granary 28 are integrally formed. The storage granary 28, the grain transfer device 29 and the grain receiving bin 7 are all fixed inside the outer shell 27 by bolts. In order to further enhance the stability between the storage granary 28 and the grain transfer device 29, the storage granary 28 is connected to the grain transfer device 29 by bolts, so that the outer shell 27 can isolate the grains in the storage granary 28, the grain transfer device 29 and the grain receiving bin 7 from the outside world, further ensuring the dryness of grains.

[0081] The granary provided in this application realizes the taking out of grains through the grain receiving bin 7. The grain receiving bin 7 is separately arranged from the storage granary 28, which can avoid the contact between the grains in the storage granary 28 and the external environment when taking out grains, so as to better realize the dry storage of grains.

[0082] During specific use, by rotating the rotating device 30, the rotating device 30 forms a rotational motion and forms the rotational motion of the grain transfer device 29 through the intermediate transmission device. The grain transfer device 29 includes a grain receiving state and a grain sending state. As Figure 16 shown, in the grain receiving state, the grain transfer device 29 is docked with the storage granary 28, and the grains in the storage granary 28 gradually leak into the grain transfer device 29 until the grain transfer device 29 is saturated; as Figure 15 shown, in the grain sending state, the grain transfer device 29 is docked with the grain receiving bin 7 and is used to transfer the grains received in the storage granary 28 into the grain receiving bin 7, thus completing the transfer of grains once. Since the volume of the grain transfer device 29 remains constant, the transfer of grains can be quantitatively achieved each time. The above grain discharging device all adopts a mechanical transmission structure, so it is more stable during the working process.

[0083] In Embodiment 2 of the present application, the grain storage bin 28, the grain transfer device 29, and the grain receiving bin 7 are arranged in the outer housing 27 in sequence from top to bottom. The grain storage bin 28 includes an upper bin body 45, a lower bin body 46, and a grain outlet 39 that are connected in sequence from top to bottom. The lower bin body 46 is in an inverted conical shape and is used to direct the grain to the grain outlet 39. The grain outlet 39 is used to connect to the grain transfer device 29 so that the grain transfer device 29 can transport the grain to the grain receiving bin 7. The grain inlet of the grain storage bin 28 is located at the top of the upper bin body 45, and the grain can be stored in the grain storage bin 28 through the grain inlet. When the grain storage in the grain storage bin 28 is too low, the grain can be sent into the grain storage bin 28 for storage through the opening. The volume of the upper bin body 45 can accommodate a large amount of stored grain, thereby reducing the number of times of adding grain to the grain storage bin 28. It can be understood that when a large storage capacity of the grain storage bin 28 is required, it can be achieved by increasing the radial area and / or the axial height of the upper bin body 45.

[0084] The lower bin body 46 is in an inverted conical shape, wherein the first end 22 of the lower bin body 46 is integrally formed with the upper bin body 45, the shape of the first end 22 of the lower bin body 46 is the same as that of the upper bin body 45, the second end 23 of the lower bin body 46 is connected to the grain outlet 39, and the shape of the second end 23 of the lower bin body 46 is the same as that of the grain outlet 39. The middle part of the lower bin body 46 uniformly transitions from the first end to the second end 23, and the maximum radial area of the grain outlet 39 is smaller than the minimum radial area of the upper bin body 45. The lower bin body 46 is used to connect the upper bin body 45 and the grain outlet 39, and through the inverted conical design, the uniform transition between the upper bin body 45 and the grain outlet 39 can be realized, which can avoid the stacking of grain at the connection between the upper bin body 45 and the lower bin body 46, and can also avoid the stacking of grain at the connection between the lower bin body 46 and the grain outlet 39, and avoid the problem of grain jamming in the grain storage bin 28, so that the grain located in the grain storage bin 28 can be stably transported to the grain transfer device 29.

[0085] The connection between the grain outlet 39 and the grain transfer device 29 realizes the purpose of transporting the grain from the grain storage bin 28 to the grain transfer device 29. The radial area of the grain outlet 39 affects the amount of grain transported to the grain transfer device 29. It can be understood that the smaller the radial area of the grain outlet 39, the smaller the amount of grain transported to the grain transfer device 29 per unit time.

[0086] In this Embodiment 2, the upper bin body 45 forms a cuboid-shaped cavity, the lower bin body 46 is in a quadrangular pyramid shape, the grain outlet 39 is connected to the tip position of the lower bin body 46, and the grain outlet 39 is in a hollow square tubular shape. Further, the grain storage bin 28 can be fixed on the outer housing 27 through connection bars and bolts. Through the cooperation of the connection bars and bolts, the connection between the grain storage bin 28 and the outer housing 27 can be made more stable.

[0087] In Embodiment 2 of the present invention, the grain outlet 39 is arranged close to one side of the grain transfer device 29, and a grain receiving port 40 is arranged on one side of the grain receiving bin 7 close to the grain transfer device 29. The grain receiving port 40 is used to receive the grain from the grain transfer device 29. The grain outlet 39 and the grain receiving port 40 are vertically distributed in the outer housing 27, so as to form a vertical flow of grain during the process of quantitatively taking grain, which is beneficial to optimizing the overall structure of the grain outlet device. The grain receiving port 40 is a rectangular through hole opened in the grain receiving bin 7. In a preferred state, the grain receiving port 40 completely covers the grain outlet 39 in the vertical projection of the grain outlet device.

[0088] In Embodiment 2 of the present invention, a grain receiving drawer 8 is arranged in the grain receiving bin 7. The grain receiving drawer 8 is slidably connected to the grain receiving bin 7. An inlet is arranged at the top of the grain receiving drawer 8. When the grain receiving drawer 8 is in the grain receiving bin 7, the inlet is correspondingly arranged with the grain receiving port 40. The grain in the grain receiving bin 7 can be processed by receiving the grain through the grain receiving drawer 8, so that the grain is easier to transfer. The corresponding arrangement of the inlet and the grain receiving port 40 enables the grain flowing down from the grain transfer device 29 to directly enter the grain receiving drawer 8.

[0089] Please refer to Figure 17 As shown, the rotating device 30 includes a rotating body 3 and a transmission rod 4. The rotating body 3 and the transmission rod 4 are coaxially arranged. The rotating body 3 is rotationally connected to the rotary motion device through the transmission rod 4. Under the rotation of the rotating body 3, the transmission rod 4 rotates, and drives the grain transfer device 29 to rotate through the rotary motion device. The function of the transmission rod 4 is to further transmit the rotational motion of the torsion body to the rotary motion device as a transmission part. The rotating disk 20 is connected to the transmission rod 4 through a transition part 48. An interference fit is provided between the transition part 48 and the rotating disk 20. A polygonal prism is arranged on the transmission rod 4. The central axis of the polygonal prism is coaxially arranged with the transmission rod 4. A polygonal hole matching the polygonal prism is arranged at the center of the transition part 48. Therefore, under the rotation of the transmission rod 4, the transition part 48 can be driven to rotate, and the transition part 48 further drives the rotating disk 20 to rotate. Among them, the transition part 48 is a disk-shaped part.

[0090] Among them, the rotary motion device includes a first gear 33 rotationally connected to the transmission rod 4 and a second gear 34 drivingly connected to the grain transfer device 29. Both the first gear 33 and the second gear 34 are straight-tooth cylindrical gears. The modulus and the tooth profile angle on the pitch circle of the first gear 33 and the second gear 34 are equal. The rotary motion device is not limited to gear transmission. In addition to the gear transmission method, it can also be chain transmission or belt transmission.

[0091] The grain transfer device 29 includes an outer housing 27 and a rotating housing for quantitatively receiving grain. The rotating housing is drivingly connected to a second gear 34. The rotating housing and the second gear 34 are connected by an intermediate shaft 11. The outer housing 27 is sleeved outside the rotating housing and fixedly connected to the outer housing 27. Through holes are provided on both the upper and lower sides of the outer housing 27. The outer housing 27 is connected to a grain outlet 39 and a grain receiving port 40 through the through holes respectively. Under the rotation of the second gear 34, the rotating housing is used to open and close the grain outlet 39 or the grain receiving port 40. The volume inside the rotating housing is equivalent. Therefore, quantitative grain taking can be carried out each time it rotates, and the volume of the rotating housing is generally the food intake of one person. The food intake of one person is about 100g - 200g.

[0092] Wherein, a grain transfer port 41 and a grain blocking surface 42 are correspondingly arranged on the surface of the rotating housing. When the grain transfer device 29 is in the grain receiving state, the grain transfer port 41 is connected to the grain outlet 39, and the grain blocking surface 42 is used to block the grain receiving port 40; in the grain transfer state, the grain transfer port 41 is connected to the grain receiving port 40, and the grain blocking surface 42 is used to block the grain outlet 39; during the rotation of the rotating housing, the grain transfer port 41 can communicate with at most one of the grain receiving port 40 or the grain outlet 39. This enables the grain to be quantitatively retained in the grain transfer device 29 regardless of how the rotating housing rotates, and prevents the situation where the grain flows unrestrictedly into the grain receiving bin 7.

[0093] Wherein, a cylindrical accommodating cavity is arranged inside the outer housing 27. The rotating housing is of a cylindrical structure. The rotating housing, the intermediate shaft 11 and the first gear 33 are coaxially arranged. The rotating housing is arranged in clearance fit with the cylindrical cavity. An opening and an arc surface are arranged on the surface of the rotating housing. The opening is longitudinally arranged along the axis of the rotating housing. The opening is the grain transfer port 41, and the arc surface is the grain blocking surface 42.

[0094] Wherein, the outer housing 27 is divided into an upper housing 43 and a lower housing 44 along the axis of the outer housing 27. The upper housing 43 is connected to the lower housing 44 through a detachable device. When the rotating housing needs to be repaired, the upper housing 43 and the lower housing 44 are separated, and the rotating housing is taken out for repair.

[0095] Please refer to Figure 18 and Figure 19As shown, a fixed shell 49 is provided outside the rotating body 3, and the fixed shell 49 is fixedly connected to the outer shell 27, wherein the rotating body 3 is a cylindrical structure, and a cylindrical cavity is provided inside the fixed shell 49 to ensure that the rotating body 3 is rotatably connected to the fixed body, wherein the end of the rotating body 3 facing outward is protruding outwardly and provided with a rotating key 38, the rotating body 3 is connected to the transmission rod 4 at one end facing inward, and the other end of the rotating body 3 connected to the transmission rod 4 is facing outward, and the rotating key 38 is fixedly connected to the rotating body 3, and the rotating member is used to drive the torsion body to rotate, so that the rotating body 3 as a whole is easier to rotate, and the outer The shell 27 is provided with a first position 5 mark corresponding to the grain receiving state and a second position 6 mark corresponding to the grain delivering state. The above two position marks are layers with obvious colors coated on the main body or protrusions carved on the outer shell 27. When the rotation key 38 corresponds to the first position 5 mark, the grain transfer device 29 is in the grain receiving state. When the rotation key 38 corresponds to the second position 6 mark, the grain transfer device 29 is in the grain delivering device. The setting of the above position marks and the rotation key 38 allows the operator to switch between the grain delivering state and the grain receiving state with more purpose and accuracy, avoiding the occurrence of the rotating body 3 turning too far.

[0096] Among them, the first position 5 mark, the second position 6 mark and the rotation key 38 are all long strip structures, so that the rotation key 38 can be more easily aligned with the first position 5 mark or the second position 6 mark during the rotation process. The first position 5 mark is vertically set on the top of the torsion body, and the second position 6 mark is parallelly set on both sides of the torsion body. In the preferred state, the line connecting the two second position 6 marks is perpendicular to the first position 5 mark.
