Description

Technical Field

[0001] This utility model is a pneumatic grain suction device, belonging to the field of grain suction equipment. Background Technology

[0002] During the grain harvest season, the harvested grain needs to be dried, often over a very large area. Collecting the dried grain is a very time-consuming and labor-intensive task. Harvesting the large areas of dried grain before sunset or before thunderstorms is necessary. Manual harvesting is not only time-consuming, labor-intensive, and inefficient, but also results in workers being covered in grime due to dust in the grain, affecting their comfort and potentially interfering with subsequent grain cleaning and processing. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pneumatic grain suction device.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A pneumatic grain suction device includes a frame, a fan and a shut-off valve on the top of the frame, an air inlet end of the fan connected to one end of an air duct, an outlet end of the air duct connected to a grain bin, a grain bin installed on top of the shut-off valve, a grain suction pipe connected to one side of the grain bin, a grain suction nozzle connected to the end of the grain suction pipe, and a grain dispensing mechanism at the bottom of the frame connected to the bottom output end of the shut-off valve.

[0006] Furthermore, the grain dispensing mechanism includes a grain bin fixed to the bottom of the frame. The grain bin has an inner cavity, and a grain outlet communicating with the bottom of the airlock is provided on the top side of the inner cavity. A turntable is rotatably connected inside the inner cavity. The center of the turntable is connected to a rotating shaft. The bottom end of the rotating shaft extends through to the bottom of the grain bin and is connected to the output shaft of the drive motor. The drive motor is installed at the bottom of the grain bin.

[0007] Furthermore, the outer circumference of the turntable is provided with a plurality of mounting grooves, which are adapted to the grain inlet. An assembly block is slidably connected in the mounting groove. The top of the assembly block is provided with a receiving groove, and a material cylinder is placed inside the receiving groove. The material cylinder corresponds to the grain inlet. The outer surface of the assembly block is provided with a pull plate, and the outer surface of the pull plate is pressed together with the inner wall of the inner cavity. The outer surface of the grain box is provided with a box door that cooperates with the assembly block.

[0008] Furthermore, the outer surface of the pull plate is fitted with ball bearings, which are pressed together with the inner wall of the inner cavity.

[0009] Furthermore, sliding grooves are provided on both inner walls of the mounting groove, and stroke limiting grooves are provided on the inner walls of the sliding grooves. Slider blocks that cooperate with the sliding grooves are provided on both outer surfaces of the assembly block, and stroke limiting sliders that cooperate with the stroke limiting grooves are provided at the ends of the sliders.

[0010] Furthermore, a mating interface is provided on one side of the outer surface of the assembly block, and a sealing block that mates with the mating interface is provided on the inner wall of the mounting groove.

[0011] Furthermore, a weight sensor, a wireless signal transceiver, and a lithium battery are installed at the bottom of the receiving slot. The weight sensor is electrically connected to an electrical control box installed on the outer surface of the frame via the wireless signal transceiver.

[0012] The beneficial effects of this utility model are:

[0013] In use, this utility model uses a fan and air duct to create negative pressure in the grain suction pipe, which then draws air from the grain on the ground through the suction pipe and suction nozzle. After entering the grain silo, the grain falls through the airlock to the grain outlet and finally enters the grain distribution mechanism.

[0014] This invention utilizes a grain distribution mechanism. Grain falls through a closed air valve to the grain inlet and finally enters the hopper. As the grain gradually accumulates in the hopper, a weight sensor on the hopper's receiving trough detects that the weight of the hopper has reached a set value. The weight sensor then transmits this information to the control box via a wireless signal transceiver. The control box activates the drive motor at the bottom of the grain bin. The drive motor rotates a turntable via a rotating shaft. The turntable rotates several assembly blocks and hoppers, causing the next unused hopper to rotate below the grain inlet and take over the grain receiving action.

[0015] This invention utilizes a ball bearing design so that, during the rotation of the assembly block and the pull plate driven by the turntable, the balls on the outer surface of the pull plate will rub against the inner wall of the inner cavity, thereby assisting the assembly block and the pull plate in rotating and improving rotational stability while avoiding wear on both.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8This utility model provides a pneumatic grain suction device, including a frame 1. A fan 2 and a shut-off valve 3 are mounted on the top of the frame 1. One end of an air duct 21 is connected to the air inlet of the fan 2, and the outlet of the air duct 21 is connected to a grain bin 4. The grain bin 4 is mounted on top of the shut-off valve 3. A grain suction pipe 5 is connected to one side of the grain bin 4, and a grain suction nozzle 6 is connected to the end of the suction pipe 5. A grain dispensing mechanism connected to the bottom output end of the shut-off valve 3 is located at the bottom of the frame 1. The bottom of the receiving tank 16 is equipped with a weight sensor, a wireless signal transceiver and a lithium battery. The weight sensor is electrically connected to the electrical control box installed on the outer surface of the frame 1 through the wireless signal transceiver. In use, the fan 2 and the air duct 21 generate negative pressure in the grain suction pipe 5, and then the grain suction pipe 5 and the grain suction nozzle 6 suck the grain on the ground under negative pressure. After the grain enters the grain bin 4, the grain will fall through the airlock 3 to the grain outlet 8 and finally enter the grain distribution mechanism.

[0028] See Figures 3-8 The grain dispensing mechanism includes a grain bin 7 fixed to the bottom of the frame 1. The grain bin 7 has an inner cavity 9. A grain outlet 8, communicating with the bottom of the airlock 3, is located on one side of the top of the inner cavity 9. A turntable 10 is rotatably connected inside the inner cavity 9. The center of the turntable 10 is connected to a rotating shaft 11. The bottom end of the rotating shaft 11 extends through to the bottom of the grain bin 7 and is connected to the output shaft of a drive motor. The drive motor is installed at the bottom of the grain bin 7. Several mounting slots 12 are formed on the outer circumference of the turntable 10, each slot matching the grain outlet 8. An assembly block 15 is slidably connected within each mounting slot 12. A mating interface is formed on one side of the outer surface of the assembly block 15. A sealing block 13, which mates with the mating interface, is provided on the inner wall of the mounting slot 12. A receiving groove 16 is formed on the top of the assembly block 15. The grain bin 6 contains a material cylinder 19, which corresponds to the grain outlet 8. The outer surface of the assembly block 15 is provided with a pull plate 17, which is pressed against the inner wall of the inner cavity 9. The outer surface of the grain bin 7 is provided with a door 20 that cooperates with the assembly block 15. Through the design of the grain distribution mechanism, the grain falls through the airlock 3 to the grain outlet 8 and finally enters the material cylinder 19. As the grain in the material cylinder 19 gradually accumulates, when the weight sensor on the receiving slot 16 of the material cylinder 19 detects that the weight of the material cylinder 19 has reached the set value, the weight sensor transmits the signal to the control box through a wireless signal transceiver. The control box starts the drive motor at the bottom of the grain bin 7. The drive motor drives the turntable 10 to rotate through the rotating shaft 11. The turntable 10 drives several assembly blocks 15 and material cylinders 19, so that the next unused material cylinder 19 rotates to the bottom of the grain outlet 8 to take over the grain receiving action.

[0029] See Figure 7 , Figure 8 The outer surface of the pull plate 17 is equipped with ball bearings, which are pressed together with the inner wall of the inner cavity 9. Through the design of the ball bearings, when the turntable 10 drives the assembly block 15 and the pull plate 17 to rotate, the ball bearings on the outer surface of the pull plate 17 will rub against the inner wall of the inner cavity 9, thereby helping the assembly block 15 and the pull plate 17 to rotate and improving rotational stability without causing wear to the assembly block 15 and the pull plate 17.

[0030] See Figures 6-7 The mounting groove 12 has sliding grooves 14 on both inner walls, and stroke limiting grooves 22 on the inner walls of the sliding grooves 14. The assembly block 15 has sliders 18 on both outer surfaces that cooperate with the sliding grooves 14. The ends of the sliders 18 have stroke limiting sliders 23 that cooperate with the stroke limiting grooves 22. The design of the sliding grooves 14 and sliders 18 improves the stability of the assembly block 15 in the mounting groove 12. The stroke limiting grooves 22 and stroke limiting sliders 23 increase the speed at which the user can pull out the assembly block 15, thereby achieving the purpose of quickly removing the material cylinder 19 from the assembly block 15 and facilitating user operation.

[0031] During operation, the blower 2 and duct 21 create negative pressure in the suction pipe 5, which in turn draws air from the grain on the ground through the suction pipe 5 and suction nozzle 6. The grain enters the grain bin 4 and falls through the airlock 3 to the grain outlet 8, finally entering the feed hopper 19. As the grain gradually accumulates in the feed hopper 19, when the weight sensor on the receiving trough 16 detects that the weight of the feed hopper 19 has reached a set value, the weight sensor transmits the signal to the control box via a wireless transceiver. The control box then activates the drive motor at the bottom of the grain bin 7, which drives the rotating shaft 11 to rotate... The turntable 10 rotates, driving several assembly blocks 15 and material cylinders 19, so that the next unused material cylinder 19 rotates to the bottom of the grain inlet 8 to take over the grain receiving action; as the turntable 10 rotates, when the material cylinder 19 filled with grain rotates to the door 20, the material cylinder 19 and the assembly block 15 can be pulled out together, and then the material cylinder 19 filled with grain can be taken out and an empty material cylinder 19 can be put in, and the above work can be repeated, thereby realizing the continuous operation of the equipment. In addition, an alarm can be added to the electrical control box, so that when the material cylinder 19 rotates to the door 20, the alarm can provide a voice reminder.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
