A multi-functional grain unloader Technical Field

[0001] This invention relates to the field of grain unloaders, and more particularly to a multifunctional grain unloader. Background Technology

[0002] After harvesting, grains need to be spread out to dry in the sun. Grains with small drying areas are mostly collected manually, while grains with larger drying areas require the use of a grain unloader. A grain unloader is an agricultural machine used for collecting, storing, and transporting bulk grains in granaries. When used in conjunction with a conveyor, it can also be used for stacking and loading onto trucks.

[0003] Traditional grain unloaders can usually only collect grain in one direction, and it is difficult to adjust the direction and angle of grain collection, which limits the operating range and makes it difficult to flexibly adapt to the collection of small spaces or scattered grains. In addition, the dust generated during operation is serious, which affects the working environment and grain quality.

[0004] Therefore, there is an urgent need for a multi-functional grain unloader to solve the problems existing in the above-mentioned technologies. Summary of the Invention

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Referring to Figures 1 to 6, this embodiment provides a multi-functional grain unloader, including a housing 1, a support 7 at the bottom of the housing 1, the housing 1 being able to rotate horizontally on the support 7, four wheels 6 respectively installed at the four corners of the bottom surface of the support 7, a grain unloading conveyor belt 2 installed on one side of the housing 1, a first conveyor belt 3 installed on the side of the support 7 away from the grain unloading conveyor belt 2, a discharge port 26 opened at the bottom of the housing 1, the discharge port 26 being located above the first conveyor belt 3, the first conveyor belt 3 transferring the grain to a transport vehicle, a scraping mechanism installed below the grain unloading conveyor belt 2, the scraping mechanism being fixedly connected to the support 7, a discharge mechanism installed above the first conveyor belt 3, the discharge mechanism being connected to the housing 1, and a dust removal mechanism installed at the top of the housing 1, the dust removal mechanism being used to collect dust inside the housing 1.

[0028] In use, the grain-tapping conveyor belt 2 is placed on the grain pile, and the grain is transported into the housing 1 via the grain-tapping conveyor belt. When no angle adjustment is required, the grain falls from the discharge port 26 onto the first conveyor belt 3. When the grain is rotated for conveying, the discharge mechanism transports the grain onto the first conveyor belt 3, eliminating the need for overall movement, saving time and improving work efficiency. The dust removal mechanism is activated simultaneously to absorb the dust generated during grain conveying inside the housing 1, thereby purifying the environment and preventing dust from spreading and causing pollution. For scattered grain on the ground that is inconvenient to collect using the grain-tapping conveyor belt 2, the scraping mechanism can clean up the scattered grain on the ground, eliminating the need for manual cleaning, saving time and effort, and increasing efficiency. This invention achieves multi-angle grain-tapping operations through the horizontal rotation of the housing 1, and the walking wheels 6 enhance mobility. The vertical layout of the discharge port 26 and the first conveyor belt 3 reduces grain transfer links and reduces spillage loss. The triple integration of the scraping mechanism, discharge mechanism, and dust removal mechanism achieves functional diversity, improves work efficiency, and reduces dust pollution.

[0029] Further refining the design, a drive unit 5 is installed on the outside of the housing 1. The drive unit 5 drives the grain-digging conveyor belt 2 to rotate around the shaft. A conveying plate 8 is installed below the grain-digging conveyor belt 2, with its top extending into the housing 1. The drive unit 5 can adjust the angle of the conveying plate 8 and the grain-digging conveyor belt 2, thereby adapting to grain piles of different heights and expanding the overall applicability.

[0030] Further refining the design, a rotary motor 21 is fixedly installed inside the bracket 7. The output shaft of the rotary motor 21 is fixedly connected to a disc, which is located on the top surface of the bracket 7 and is fixedly connected to the housing 1. When the grain-harvesting needs to adjust its angle, the rotary motor 21 is started to drive the disc to rotate, which in turn drives the housing 1 to rotate, thereby achieving angle adjustment.

[0031] Further refining the design, the scraping mechanism includes a fixing plate 16 fixedly connected to the bracket 7. A connecting pipe 15 passes through the fixing plate 16. One end of the connecting pipe 15 is located on the first conveyor belt 3, and the other end is connected to a flexible hose 14. The bottom of the flexible hose 14 is connected to a negative pressure box 13, and a scraper 17 is fixedly connected to the bottom of the negative pressure box 13. The scraper 17 is used to scrape off grains scattered on the ground. In use, the scraper 17 contacts the ground, collects the grains on the ground, and absorbs the grains through the negative pressure box 13. The grains fall onto the first conveyor belt 3 through the flexible hose 14 and the connecting pipe 15, thereby realizing the collection and transfer of scattered grains on the ground. The flexible hose 14 is designed to adapt to the uneven ground to avoid equipment damage caused by rigid connections.

[0032] Further refining the design, the negative pressure box 13 is fixedly connected to a connecting shaft 19. Connecting plates 20 are rotatably connected to both ends of the connecting shaft 19. The connecting plates 20 are fixedly connected to the bracket 7. A drive motor 18 is fixedly installed on any of the connecting plates 20, and the output shaft of the drive motor 18 is fixedly connected to the connecting shaft 19. The combination of the connecting shaft 19 and the drive motor 18 allows for adjustable scraper 17 angles, adapting to different terrains such as flat ground or slopes. When not in use, it can be stored away, saving space.

[0033] Further refining the scheme, the discharge mechanism includes a discharge box 12 connected to the housing 1. A pair of telescopic tubes 9 are connected to the discharge box 12, and a drop box 10 is connected to the bottom of the telescopic tubes 9. The drop box 10 is located above the first conveyor belt 3. The drop box 10 is fixedly connected to the side plate on the first conveyor belt 3 through a bent rod 11. A second conveyor belt 24 is provided inside the housing 1. The end of the discharge box 12 is located at the top of the second conveyor belt 24, and the bottom of the second conveyor belt 24 is located above the drop port 26. The top of the second conveyor belt 24 is rotatably connected to the inner wall of the housing 1. The output end of a hydraulic rod 25 is hinged to the bottom of the second conveyor belt 24. The end of the hydraulic rod 25 away from the second conveyor belt 24 is hinged to the inner wall of the housing 1. When the angle needs to be shifted for grain removal, the hydraulic rod 25 extends, causing the second conveyor belt 24 to rotate, so that the bottom of the second conveyor belt 24 is below the third conveyor belt 27. At this time, the grain will not fall at the discharge port 26, but will be conveyed by the second conveyor belt 24. The second conveyor belt 24 conveys the grain to the discharge box 12. The grain in the discharge box 12 falls into the discharge box 10 through the telescopic tube 9, and then falls onto the first conveyor belt 3 through the discharge box 10. In this way, the grain can be conveyed even when the angle is shifted, without spillage, without the need for overall movement, thus improving work efficiency.

[0034] Further refining the design, a third conveyor belt 27 is fixedly installed inside the housing 1. One end of the third conveyor belt 27 is located above the discharge port 26, and the other end is located below the conveying plate 8. The grain is fed onto the conveying plate 8 by the grain conveyor belt 2, and the grain on the conveying plate 8 falls onto the third conveyor belt 27 for transport. The third conveyor belt 27 then delivers the grain into the discharge port 26, causing the grain to fall onto the first conveyor belt 3. The first conveyor belt 3 then transports the grain to a transport vehicle to complete the transfer.

[0035] Further refining the scheme, the dust removal mechanism includes a negative pressure box 4 fixedly connected to the top surface of the housing 1. The bottom surface of the negative pressure box 4 is connected to a first adsorption pipe 22 and a second adsorption pipe 23. The first adsorption pipe 22 extends into the housing 1 and is located above the second conveyor belt 24. The second adsorption pipe 23 extends into the housing 1 and is located above the end of the third conveyor belt 27 near the conveying plate 8. The first adsorption pipe 22 adsorbs the dust generated during the conveying of materials on the second conveyor belt 24, and the second adsorption pipe 23 adsorbs the dust generated when materials fall onto the third conveyor belt 27. This effectively cleans the dust inside the housing 1, prevents dust from escaping, and reduces environmental pollution.

[0036] Further refining the design, a partition 28 is fixedly connected inside the negative pressure chamber 4. The lower part of the partition 28 communicates with the first adsorption tube 22 and the second adsorption tube 23. A filter cartridge 31 is detachably connected to the negative pressure chamber 4. The bottom of the filter cartridge 31 passes through the partition 28, and a knob 29 is fixedly connected to the top of the filter cartridge 31. The top of the filter cartridge 31 is threadedly connected to the negative pressure chamber 4, and the knob 29 is rotatably connected to the top surface of the negative pressure chamber 4. The bottom of the partition 28 has an expansion structure to increase the air intake space. The filter cartridge 31 adopts a threaded connection, which facilitates the maintenance of the filter cartridge 31, and the filter cartridge 31 can perform preliminary filtration to ensure a good filtration effect.

[0037] Further refining the design, a filter sleeve 30 is fitted onto the outside of the filter cartridge 31. The filter sleeve 30 uses multi-layer composite filter material, which can effectively intercept particulate matter such as dust. The fact that the filter sleeve 30 is fitted onto the outside of the cartridge makes it easier to clean or replace the filter sleeve 30 and facilitates the maintenance of the dust removal mechanism.
