[0001] The utility model relates to the technical field of grain transportation, and particularly relates to a residual grain cleaning device. Background Art

[0002] After the grain transport vehicle transports the grain to the outside of the granary, a conveyor belt is needed to transport the grain into the granary. When unloading the grain from the grain transport vehicle, usually a long funnel is placed on the side of the carriage of the grain transport vehicle, and a conveyor belt is arranged below the funnel. The baffle on the side of the carriage of the grain transport vehicle is opened, and the grain pours down into the funnel, and then the grain is transported into the granary through multiple conveyor belts. However, in the process of unloading the grain, the following defects exist:

[0003] After part of the grain in the carriage pours down, there is still a lot of grain left in the carriage. At this time, it is necessary to manually push the remaining grain in the carriage into the funnel, which is time-consuming and laborious, resulting in low unloading efficiency. Content of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the technical defects described in the background art.

[0005] Therefore, an object of the utility model is to provide a residual grain cleaning device, aiming to solve the problem that when the grain is put into the warehouse in the prior art, it is time-consuming and laborious to unload the residual grain in the carriage of the grain transport vehicle, resulting in low unloading efficiency.

[0006] To achieve the above object, an embodiment of one aspect of the present utility model provides a residual grain cleaning device, including a funnel. A collecting box is slidably connected to the top of the funnel. An air box is fixedly installed at the top of the collecting box. A first motor is fixedly installed at the top of the air box. An impeller is fixedly connected to the output end of the first motor. An air outlet is fixedly connected to one side of the air box. A feed pipe is fixedly connected to the outer surface of the collecting box. A corrugated pipe is fixedly installed on the outer surface of the feed pipe. One end of the corrugated pipe away from the feed pipe is fixedly connected to a suction head. A filter plate is fixedly installed on the inner wall of the collecting box. A support is fixedly connected to the top of the air box. A base is fixedly connected to the top of the support. A toothed disc is rotatably connected to the top of the base. A second motor is fixedly installed on one side of the support. A gear is fixedly connected to the output end of the second motor. The gear meshes with the toothed disc. A first support platform is fixedly connected to the top of the toothed disc. A U-shaped seat is fixedly connected to the top of the first support platform. A driving wheel is rotatably connected inside the U-shaped seat. A third motor is fixedly installed on one side of the U-shaped seat. The output end of the third motor is fixedly connected to the axle center of the driving wheel. An extension arm is slidably connected inside the U-shaped seat. One end of the extension arm is fixedly connected to a mounting seat. A worm and worm gear lift is fixedly installed on the top of the mounting seat. The bottom end of the lifting screw rod of the worm and worm gear lift is fixedly connected to the suction head.

[0007] Preferably, according to any of the above solutions, a second support platform is fixedly connected to the top of the toothed disc. A rectangular groove is fixedly connected to the top end of the second support platform. The extension arm is slidably connected inside the rectangular groove. A toothed groove is formed on the top of the extension arm. The driving wheel meshes with the toothed groove, improving the stability of the extension arm during movement.

[0008] Preferably, according to any of the above solutions, a discharge pipe is fixedly connected to the bottom of the collecting box. A cover plate is hinged to the outlet end of the discharge pipe, having the function of discharging while sucking, improving the efficiency of residual grain cleaning.

[0009] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0010] 1. When cleaning the residual grain in the carriage, start the third motor to drive the driving wheel to rotate, so that the extension arm extends into the carriage. Then drive the worm and worm gear lift through the fourth motor, so that the suction head descends and fits the inner bottom of the carriage. Then start the first motor, and the impeller rotates to generate suction, thereby sucking the residual grain in the carriage into the collecting box. Then adjust the position of the suction head by telescoping the extension arm, driving the toothed disc to rotate by the second motor, and sliding the collecting box on the guide rail, so that the suction head can suck the residual grain on the carriage into the collecting box in all directions, thus completing the cleaning of the residual grain. There is no need for manual entry into the vehicle, saving time and effort, and improving the efficiency of unloading grain.

[0011] 2. By setting rectangular grooves, the rectangular grooves cooperate with the U-shaped grooves to provide two-point support for the extension arm, thereby improving the stability of the extension arm. Moreover, a toothed groove is provided at the top of the extension arm, and the driving wheel drives the extension arm to expand and contract by meshing with the toothed groove, without slipping, so the stability during the expansion and contraction process of the extension arm is further improved.

[0012] 3. By hinging the cover plate at the outlet end of the blanking pipe, when there is no grain in the aggregate bin, the cover plate droops to block the blanking pipe. Thus, when the motor is started to drive the impeller to rotate, the external air can only enter through the feed pipe, ensuring sufficient suction at the suction head to suck in the grain. When the grain enters the aggregate bin, the grain falls into the blanking pipe and pushes the cover plate open to fall into the funnel. During this process, the grain blocks the blanking pipe, ensuring the suction at the suction head. Therefore, it can suck up residual grain while discharging residual grain, with a simple and reasonable structure, improving the practicability.

[0022] The present invention provides a residual grain cleaning device.

[0023] Embodiment 1:

[0024] Such as Figures 1-4As shown in the figure, it includes a funnel 1. A collecting box 2 is slidably connected to the top of the funnel 1. An air box 3 is fixedly installed on the top of the collecting box 2. A first motor 31 is fixedly installed on the top of the air box 3. The output end of the motor 31 penetrates into the interior of the air box 3. The output end of the first motor 31 is fixedly connected to an impeller 32. An air outlet 33 is fixedly connected to one side of the air box 3. A feed pipe 21 is fixedly connected to the outer surface of the collecting box 2. The motor 31 drives the impeller 32 to rotate at a high speed, thereby sucking air through the feed pipe 21 and discharging the air from the air outlet 33 by centrifugal force. A corrugated pipe 22 is fixedly installed on the outer surface of the feed pipe 21. One end of the corrugated pipe 22 away from the feed pipe 21 is fixedly connected to a suction head 23. A filter plate 24 is fixedly installed on the inner wall of the collecting box 2 to block the grains and avoid the problem that the grain kernels are sucked into the impeller 32. A bracket 7 is fixedly connected to the top of the air box 3. A base 71 is fixedly connected to the top of the bracket 7. A toothed disc 72 is rotatably connected to the top of the base 71. A rotating shaft is fixedly connected to the bottom of the toothed disc 72. A bearing is provided at the axis of the base 71. The rotating shaft at the bottom of the toothed disc 72 and the bearing at the axis of the base 71 are rotatably connected to the base 71. A second motor 73 is fixedly installed on one side of the bracket 7. The output end of the second motor 73 is fixedly connected to a gear 74. The gear 74 meshes with the toothed disc 72. The second motor 73 can drive the toothed disc 72 to rotate through the gear 74. A first support platform 8 is fixedly connected to the top of the toothed disc 72. A U-shaped seat 81 is fixedly connected to the top of the first support platform 8. A driving wheel 82 is rotatably connected to the interior of the U-shaped seat 81. A third motor 83 is fixedly installed on one side of the U-shaped seat 81. The output end of the third motor 83 is fixedly connected to the axis of the driving wheel 82. An extension arm 9 is slidably connected to the interior of the U-shaped seat 81. The third motor 83 can drive the driving wheel 82 to rotate, and the rotating driving wheel 82 can drive the extension arm 9 to slide. One end of the extension arm 9 is fixedly connected to a mounting seat 91. A worm and worm gear lift 10 is fixedly installed on the top of the mounting seat 91. A hole is provided in the middle of the mounting seat 91. The lifting screw rod of the worm and worm gear lift 10 passes through the hole to the lower part of the mounting seat 91 through the hole. The bottom end of the lifting screw rod of the worm and worm gear lift 10 is fixedly connected to the suction head 23, thereby forming a rigid fixed end. The worm and worm gear lift 10 can drive the suction head 23 to lift and lower.

[0025] Specifically, as Figure 3 shown, a fourth motor 101 is fixedly connected to the end of the worm of the worm and worm gear lift 10. The fourth motor 101 is fixedly installed on the mounting seat 91. By driving the worm in the worm and worm gear lift 10, the lifting screw rod in the worm and worm gear lift 10 is lifted and lowered. A guide rod 102 is slidably connected to the interior of the mounting seat 91. The bottom end of the guide rod 102 is fixedly connected to the suction head 23 to limit the lifting screw rod in the worm and worm gear lift 10 and avoid the problem that the lifting screw rod rotates synchronously with the worm in the worm and worm gear lift 10 and thus cannot be lifted and lowered.

[0026] Specifically, as Figure 1 shown, a support frame 11 is fixedly connected to the bottom of the funnel 1, and a universal wheel 12 is fixedly installed at the bottom of the support frame 11. The setting of the universal wheel 12 facilitates the movement of the funnel 1, and the universal wheel 12 adopts a universal wheel structure with a brake, which is convenient for fixing the funnel 1 and avoiding the problem of movement during discharging. A conveyor belt 6 is fixedly installed below the funnel 1, and the frames on both sides of the conveyor belt 6 are fixedly connected to the inner side of the support frame 11 through support rods, so as to fixedly install the conveyor belt 6 below the funnel 1 for transporting the grains discharged through the funnel 1.

[0027] Specifically, as Figure 1 shown, guide rails 13 are fixedly connected to both sides of the top of the funnel 1, and a plurality of support legs 5 are fixedly connected to the outer surface of the aggregate bin 2. Two rollers 51 are rotatably connected to the inner side of each support leg 5. The two rollers 51 are arranged up and down and have a gap in the middle. The two rollers 51 are respectively attached to the upper surface and the lower surface of the guide rail 13. Limit blocks 14 are fixedly connected to both ends of the guide rail 13. When the aggregate bin 2 slides to the edge of the guide rail 13, the limit blocks 14 can block the rollers 51 to avoid the problem of the aggregate bin 2 slipping.

[0028] In this embodiment, the third motor 83 and the drive wheel 82 cooperate with the extension arm 9 to adjust the horizontal extension distance of the fixed suction head 23 at the rigid fixed end; the worm gear and worm elevator 10 adjusts the vertical height of the fixed suction head 23 at the fixed end; the second motor 73, the gear 74, and the tooth disc 72 cooperate to adjust the rotation angle of the fixed suction head 23 at the rigid fixed end in the horizontal plane. These parts together form a position adjustment mechanism that can adjust the position of the suction head 23 in all directions.

[0029] Embodiment Two:

[0030] As Figure 2 shown, on the basis of Embodiment One, a second support platform 84 is fixedly connected to the top of the tooth disc 72, and a rectangular groove 85 is fixedly connected to the top end of the second support platform 84. The extension arm 9 is slidably connected to the inside of the rectangular groove 85 to provide two-point support for the extension arm 9 and improve the stability of the extension arm 9. A tooth groove 92 is formed at the top of the extension arm 9, and teeth are provided on the surface of the drive wheel 82. The drive wheel 82 meshes with the tooth groove 92, so that when the drive wheel 82 drives the extension arm 9 to expand and contract, it is more stable and does not slip.

[0031] Embodiment Three:

[0032] As Figure 4As shown, on the basis of Embodiment 1 or Embodiment 2, a blanking pipe 4 is fixedly connected to the bottom of the aggregate bin 2. The blanking pipe 4 is in an L shape, and the lower half of the blanking pipe 4 inclines downward. A cover plate 41 is hinged to the outlet end of the blanking pipe 4. The cover plate 41 is vertically downward due to gravity. At this time, the cover plate 41 can block the discharge port of the blanking pipe 4, so that when the impeller 32 rotates to generate suction, air will not enter the aggregate bin 2 through the blanking pipe 4.

[0033] Embodiment 4:

[0034] The difference from Embodiment 1 is that the extension arm 9 can also be electrically driven, and the linear displacement output end of the electric push rod faces the side where the truck is located. At this time, the third motor 83 and the drive wheel 82 for driving the movement of the extension arm 9 can both be deleted. At this time, a part of the corrugated pipe 22 can be connected to the base of the electric push rod, and another part of the corrugated pipe 22 can be connected to the linear displacement output end of the electric push rod, so as to achieve the purpose of synchronous expansion and contraction of the corrugated pipe 22 with the electric push rod, and avoid the visual mess caused by the pipeline directly resting on the funnel.

[0035] Of course, it can be understood that the electric push rod can also be replaced by a hydraulic cylinder.

[0036] Embodiment 5:

[0037] The difference from Embodiment 4 is that the bracket 7 is an electric push rod. The base 71 is fixedly connected to the linear displacement output end of the electric push rod. The second motor 73 is fixed on the base 71. The telescopic movement of the electric push rod drives the base 71 and the first support platform 8 and the extension arm 9 on the base 71 to move up and down, so as to achieve the purpose of adjusting the height of the suction head 23. At this time, the worm gear and worm elevator 10 can be omitted, and the suction head 23 is directly fixed to the end of the extension arm 9, and the end of the extension arm 9 is used as a rigid fixed end.

[0038] The working principle of the present utility model is as follows: When in use, the funnel 1 is pushed to the side of the carriage of the grain transport vehicle, and then the baffle of the carriage is opened, so that the grain in the carriage pours down into the funnel 1. The funnel 1 then guides the grain onto the conveyor belt 6. When the grain in the carriage cannot pour down due to gravity, the third motor 83 can be started to drive the driving wheel 82 to rotate, so that the extension arm 9 extends into the carriage. Then, the worm gear and worm elevator 10 is driven by the fourth motor 101, so that the suction head 23 descends and fits the surface of the remaining grain. Then, the first motor 31 is started, and the impeller 32 rotates to generate suction, so as to suck the residual grain in the carriage into the aggregate bin 2. Then, the telescopic extension arm 9 and the second motor 73 drive the gear disk 72 to rotate, and the aggregate bin 2 is slid on the guide rail 13, so as to adjust the position of the suction head 23, so that the suction head 23 can suck the residual grain on the carriage into the aggregate bin 2 in all directions, thus completing the cleaning of the residual grain. And the grain in the aggregate bin 2 falls into the blanking pipe 4 due to gravity. The grain pushes the cover plate 41 to open the blanking pipe 4 due to gravity, so that the grain in the aggregate bin 4 can fall into the funnel 1 through the blanking pipe 4.

[0039] Compared with the prior art, the present utility model has the following beneficial effects relative to the prior art:

[0040] 1. When cleaning the residual grain in the carriage, the third motor 83 is started to drive the driving wheel 82 to rotate, so that the extension arm 9 extends into the carriage. Then, the worm gear and worm elevator 10 is driven by the fourth motor 101, so that the suction head 23 descends and fits the inner bottom of the carriage. Then, the first motor 31 is started, and the impeller 32 rotates to generate suction, so as to suck the residual grain in the carriage into the aggregate bin 2. Then, the telescopic extension arm 9 and the second motor 73 drive the gear disk 72 to rotate, and the aggregate bin 2 is slid on the guide rail 13, so as to adjust the position of the suction head 23, so that the suction head 23 can suck the residual grain on the carriage into the aggregate bin 2 in all directions, thus completing the cleaning of the residual grain. There is no need for manual entry into the vehicle, which saves time and effort and improves the efficiency of unloading grain.

[0041] 2. By providing the rectangular groove 85, the rectangular groove 85 cooperates with the U-shaped groove 81 to provide two-point support for the extension arm 9, thus improving the stability of the extension arm 9. And a tooth groove 92 is provided at the top of the extension arm 9, and the driving wheel 82 drives the extension arm 9 to expand and contract by meshing with the tooth groove 92, without slipping, so that the stability of the extension arm 9 during the expansion and contraction process is further improved.

[0042] 3. By hinging the cover plate 41 at the outlet end of the blanking pipe 4, when there is no grain in the aggregate bin 2, the cover plate 41 droops to block the blanking pipe 4. Thus, when the motor 31 is started to drive the impeller 32 to rotate, the outside air can only enter through the feed pipe 21, ensuring sufficient suction at the suction head 24 to suck in the grain. When the grain enters the aggregate bin 2, the grain falls into the blanking pipe 4 and pushes the cover plate 41 to fall into the funnel 1. During this process, the grain blocks the blanking pipe 4, ensuring the suction at the suction head 24. Therefore, it can suck and discharge residual grain simultaneously, with a simple and reasonable structure, improving the practicability.

[0043] 4. The aggregate bin 2 is slidably connected to the guide rail 13 at the top of the funnel 1 through rollers 51. In the way of rolling friction sliding, the friction force is small, making the sliding of the aggregate bin 2 smoother. Therefore, when cleaning the residual grain in the carriage, it is convenient for the movement of the aggregate bin 2, facilitating the cleaning of the residual grain in any corner of the carriage.

[0044] 5. By fixing the conveyor belt 6 under the funnel 1, the funnel 1 and the conveyor belt 6 are integrated into one. In this way, when the funnel 1 is pushed to the side of the carriage, the conveyor belt 6 is in place at the same time, without the need to push the conveyor belt 6 separately, saving time and effort.
