[0037] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0038] According to an embodiment of this utility model, an intelligent grain unloading device based on a multi-stage linkage auger is provided, comprising: a grain silo body 1 having a grain storage silo; a vertical auger 2 disposed on the grain silo body 1; a horizontal auger 3 disposed on the grain silo body 1, the input end of the horizontal auger 3 being connected to the output end of the vertical auger 2, and the horizontal auger 3 being drivenly connected to the vertical auger 2 through a first gearbox 4; at least one grain silo auger 5 disposed on the grain silo body 1; one end of the grain silo auger 5 being connected to the grain storage silo, and the other end being connected to the vertical auger 2; a drive assembly disposed on the grain silo body 1, and its output end being drivenly connected to the vertical auger 2 through a second gearbox 6; and a clutch 7 disposed on the side of the grain silo body 1; the input end of the clutch 7 being drivenly connected to the input end of the second gearbox 6, and the output end of the clutch 7 being drivenly connected to the grain silo auger 5 through a first transmission assembly.

[0039] It should be noted that the horizontal auger 3 is located above the vertical auger 2; the end of the horizontal auger 3 that is away from the vertical auger 2 is the output end.

[0040] In this embodiment, when unloading grain is required, firstly, the drive assembly starts and drives the vertical auger 2 to rotate via the second gearbox 6. Then, the vertical auger 2 drives the horizontal auger 3 to rotate simultaneously via the first gearbox 4, thereby discharging the grain from both the vertical and horizontal augers. Next, by controlling the clutch 7 to close, the power input from the drive assembly to the input end of the second gearbox 6 is transmitted to the first transmission assembly via the clutch 7. The first transmission assembly then drives the grain silo auger 5 to rotate, continuously transporting the grain from the grain silo to the vertical auger 2, and finally discharging it from the horizontal auger 3 for loading. After unloading stops, the clutch 7 can be disengaged to disconnect the power transmission between the first transmission assembly and the second gearbox 6, thus stopping the grain silo auger 5. After the grain is discharged during the preset working time of the vertical auger 2 and the horizontal auger 3, the drive component controls the vertical auger 2 and the horizontal auger 3 to stop working, avoiding idling losses of the grain bin auger 5. By setting up the clutch 7 and the first transmission component, multi-stage transmission control is realized, realizing the linkage between the vertical auger 2, the horizontal auger 3 and the grain bin auger 5, improving the flexibility of control. The working sequence and speed of the vertical auger 2, the horizontal auger 3 and the grain bin auger 5 can be adjusted according to actual needs, ensuring the continuity of the grain unloading process and improving the unloading efficiency to meet the needs of large-scale and high-efficiency operations in modern agriculture. In addition, the transmission through the first gearbox 4 and the second gearbox 6 improves the stability and reliability of the transmission, and improves the overall working performance and service life of the grain unloading device.

[0041] In one embodiment, such as Figure 1 , Figure 3 and Figure 6As shown, the first transmission assembly includes a first sprocket 8, a second sprocket 9, and a first chain 10; the first sprocket 8 is coaxially disposed at the output end of the clutch 7, and the second sprocket 9 is coaxially disposed with the grain silo auger 5; the first sprocket 8 is drivenly connected to the second sprocket 9 through the first chain 10.

[0042] It should be noted that the first chain 10 is wound around the first sprocket 8 and the second sprocket 9, and meshes with the first sprocket 8 and the second sprocket 9.

[0043] In this embodiment, the output end of the clutch 7 is connected to the first sprocket 8. When the clutch 7 is closed, the drive assembly drives the input end of the second gearbox 6 to rotate. The input end of the second gearbox 6 then transmits power to the input end of the clutch 7, and then transmits power to the output end of the clutch 7. The first sprocket 8 rotates together with the output end of the clutch 7. Then, the first sprocket 8 drives the second sprocket 9 to rotate through the first chain 10. Then, the second sprocket 9 drives the grain silo auger 5 to rotate, realizing multi-stage power transmission.

[0044] In one embodiment, such as Figure 1 , Figure 3 and Figure 6 As shown, the first transmission assembly also includes a first adjusting sprocket 11; the first adjusting sprocket 11 is slidably connected to the grain bin body 1 via a first adjusting member; the first adjusting sprocket 11 is rotatably connected to the first adjusting member, and the first adjusting sprocket 11 abuts against the outside of the first chain 10 for adjusting the tension of the first chain 10.

[0045] In this embodiment, by setting a first adjusting sprocket 11, and the first adjusting sprocket 11 being slidably connected to the grain silo body 1 via a first adjusting member, when installing the first chain 10, the first adjusting member can be moved away from the first chain 10 on the grain silo body 1, so that the first adjusting sprocket 11 is away from the first chain 10, so as to loosen the first adjusting sprocket 11 for installation or disassembly. Alternatively, after the first chain 10 is wound around the first sprocket 8 and the second sprocket 9, the first adjusting member can be moved closer to the first chain 10 on the grain silo body 1 and abut against the first chain 10, so as to tighten the first chain 10, prevent the first chain 10 from falling off during transmission, and ensure the stability of transmission.

[0046] Specifically, the first adjusting component includes a first fixed seat and a first bolt assembly. The grain silo body 1 is provided with a corresponding first sliding groove. The first fixed seat is adapted to slide in the first sliding groove through the first bolt assembly. The first adjusting sprocket 11 is rotatably sleeved on the first fixed seat. The first bolt assembly is loosened to slide in the first sliding groove, and the first bolt assembly is tightened to fix it after moving to a preset distance.

[0047] In one embodiment, such as Figure 1 , Figure 3 and Figure 6 As shown, the drive assembly is connected to the input end of the second gearbox 6 via the second transmission assembly, and the output end of the second gearbox 6 is connected to the vertical auger 2.

[0048] In this embodiment, by setting a second transmission component, the power from the output end of the drive component is transmitted to the input end of the second gearbox 6, which facilitates the arrangement of the relative positions of the drive component and the second gearbox 6, making the overall structure more reasonable and compact, and improving space utilization.

[0049] In one embodiment, such as Figure 1 , Figure 3 and Figure 6 As shown, the second transmission assembly includes a third sprocket 12, a fourth sprocket 13, and a second chain 14; the third sprocket 12 is rotatably mounted on the grain silo body 1; the output end of the drive assembly is driven to the third sprocket 12 and is used to drive the third sprocket 12 to rotate; the fourth sprocket 13 is coaxially mounted with the input end of the second gearbox 6; the third sprocket 12 is driven to the fourth sprocket 13 via the second chain 14.

[0050] In this embodiment, the third sprocket 12 can be driven to rotate through the output end of the drive component. The third sprocket 12 then drives the fourth sprocket 13 to rotate through the second chain 14. The fourth sprocket 13 then transmits power to the input end of the second gearbox 6, so that the output end of the second gearbox 6 drives the vertical auger 2 to rotate, thereby realizing transmission. This facilitates the arrangement of the relative positions of the drive component and the second gearbox 6, making the overall structure more reasonable and compact, and improving space utilization.

[0051] Specifically, such as Figures 1 to 3 As shown, the drive assembly includes a drive component and a power output shaft 16 disposed at the output end of the drive component. The power output shaft 16 is coaxially connected to the third sprocket 12. The input end of the second gearbox 6 is provided with a transmission shaft, which is parallel to the power output shaft 16. The transmission shaft is connected to the input end of the clutch 7, and the fourth sprocket 13 is sleeved on the transmission shaft, thereby performing transmission in sequence.

[0052] Specifically, the driving component can be a drive motor or other power source.

[0053] In one embodiment, such as Figure 1 , Figure 3 and Figure 6 As shown, the second transmission assembly also includes a second adjusting sprocket 15; the second adjusting sprocket 15 is slidably connected to the grain bin body 1 via a second adjusting member; the second adjusting sprocket 15 is rotatably connected to the second adjusting member, and the second adjusting sprocket 15 abuts against the outside of the second chain 14 to adjust the tension of the second chain 14.

[0054] In this embodiment, by setting a second adjusting sprocket 15, which is slidably connected to the grain silo body 1 via a second adjusting member, when installing the second chain 14, the second adjusting member can be moved away from the second chain 14 on the grain silo body 1, so that the second adjusting sprocket 15 is away from the second chain 14, making it easier to loosen the second adjusting sprocket 15 for installation or disassembly. Alternatively, after the second chain 14 is wound around the third sprocket 12 and the fourth sprocket 13, the second adjusting member can be moved closer to the second chain 14 on the grain silo body 1 and abut against the second chain 14, thereby tightening the second chain 14, preventing the second chain 14 from falling off during transmission, and ensuring the stability of transmission.

[0055] Specifically, the second adjusting component includes a second fixed seat and a second bolt assembly. The grain silo body 1 is provided with a corresponding second sliding groove.

The second bolt assembly is loosened to slide in the second sliding groove, and the second bolt assembly is tightened to fix it after moving to a preset distance.

[0056] In one embodiment, such as Figure 4 As shown, there are two grain augers 5, which are located on both sides of the vertical auger 2 and are perpendicular to the vertical auger 2.

[0057] In this embodiment, two grain augers 5 are provided to increase the output of grain conveyed to the vertical auger 2, ensure a continuous supply of grain to the vertical auger 2, avoid interruption, and ensure unloading efficiency. In addition, the grain augers 5 and the vertical auger 2 are arranged vertically, which facilitates the arrangement of the second transmission component and the clutch 7 to achieve linkage and improve working efficiency.

[0058] In one embodiment, clutch 7 is an electromagnetic clutch.

[0059] In this embodiment, the clutch 7 is an electromagnetic clutch, which can realize power output and disconnection by energizing or de-energizing, making it convenient to control.

[0061] In this embodiment, a controller is set up to control the drive assembly, clutch 7, detection component, vertical auger 2, horizontal auger 3, and grain silo auger 5, realizing the linkage of various components. During the unloading process, the detection component monitors the grain storage level in the grain silo in real time. When the grain storage level in the grain silo is too low, the speed of the grain silo auger 5 is reduced, or the clutch 7 is controlled to disengage so that the grain silo auger 5 stops working, avoiding idling losses. It can accurately control the start, stop, and speed of each auger, and adjust the unloading process according to the actual situation, making the unloading operation more intelligent and automated, and meeting the diversified needs of modern agricultural production.

[0062] Specifically, the detection device can be a weighing sensor, ultrasonic sensor, laser sensor, or capacitive level sensor, etc., and the specific selection can be made according to the actual situation.

[0063] In one embodiment, the intelligent grain unloading device based on multi-stage linkage augers also includes a speed sensor, which is communicatively connected to the controller; the vertical auger 2, the horizontal auger 3, and the grain bin auger 5 are all equipped with speed sensors.

[0064] In this embodiment, a speed sensor is set up so that the controller can detect the speed of the vertical auger 2, the horizontal auger 3 and the grain bin auger 5, thereby improving the control accuracy. If the speed of the vertical auger 2 or the horizontal auger 3 is detected to be abnormal, such as too low or too high, the controller will immediately issue an alarm signal and cut off the power source to protect the unloading device and avoid equipment damage.

[0065] Specifically, the first gearbox 4 is equipped with a first gear transmission assembly to realize the transmission between the second transmission assembly and the vertical auger, thereby improving the stability and reliability of the transmission and enhancing the overall working performance and service life of the unloading device.

[0066] Specifically, the second gearbox 6 is equipped with a second gear transmission assembly to realize the transmission between the horizontal auger 3 and the vertical auger, and the transmission direction can be changed as needed to improve the stability and reliability of the transmission, thereby improving the overall working performance and service life of the unloading device.

[0068] The specific working process of the intelligent grain unloading device based on a multi-stage linkage auger provided in this embodiment is as follows:

[0069] 1. Start the grain unloading operation. The third sprocket 12 rotates under the drive of the power output shaft 16, which drives the fourth sprocket 13 to rotate through the second chain 14, thereby driving the second gearbox 6 to work, so that the vertical auger 2 and the horizontal auger 3 rotate at the same time, and discharge the grain in the auger outward.

[0070] 2. According to the program settings, 10-15 seconds after the third sprocket 12 starts, the controller controls the clutch 7 to be energized, the first sprocket 8 starts to rotate, and drives the two second sprockets 9 to rotate through the first chain 10. The two second sprockets 9 drive the two grain silo augers 5 to rotate respectively, so that the grain in the grain storage silo is continuously discharged to the vertical auger 2.

[0071] 3. Vertical auger 2 lifts the grain discharged from the grain storage silo, and then discharges the grain through horizontal auger 3 for loading onto trucks; during the unloading process, the detection components and speed sensors detect the grain storage in the grain storage silo, the speed parameters of vertical auger 2, horizontal auger 3 and grain silo auger 5 in real time, and feed the data back to the controller.

[0072] 4. Based on the data fed back from the detection components and the speed sensor, the controller adjusts the speed of the third sprocket 12 and the working status of the clutch 7 in real time. When the grain storage in the grain silo is low, the controller reduces the speed of the third sprocket 12 or controls the clutch 7 to cut off the power and stop the rotation of the grain silo auger 5 to avoid idling losses. When the speed of the vertical auger 2 or the horizontal auger 3 is abnormal, the controller issues an alarm signal and takes corresponding protective measures to ensure the safe operation of the unloading device.

[0073] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
