Description

Technical Field

[0001] The invention relates to the technical field of grain conveyors, and in particular to a grain scraper conveyor for storage. Background Art

[0002] Grain storage refers to the process of storing and preserving grain (such as rice, wheat, corn, soybeans, etc.) after harvest. Its main purpose is to ensure the supply security of grain, prevent grain loss during storage, and ensure that grain can be sold, distributed and consumed at the right time. Grain storage is an important link in the agricultural production chain and plays a vital role in national food security and social stability. Scraper transport is a common material conveying system in grain storage, especially in large grain storage facilities (such as silos or flat-top warehouses). The scraper transport system uses scraper chains or scrapers to transport grain, grains or other materials, and is efficient and stable.

[0003] Existing scraper conveyors cannot adjust the angle quickly and accurately according to different terrains and transportation needs. In some special environments (such as ramps, narrow passages, etc.), traditional conveyors may not be able to adjust the optimal angle, resulting in reduced transportation efficiency, or even material loss or jamming. The design is not compact enough in terms of storage and transportation, and the equipment is large in size, requiring more space for transportation and storage, especially in an environment where frequent movement and adjustment of equipment is required. Inconvenient storage may increase the complexity of operation. There are deficiencies in stability and safety. The scraper and conveyor frame are not stable enough, and the equipment is prone to vibration, displacement or jamming, resulting in reduced transportation efficiency or mechanical damage. Therefore, the present invention proposes a grain scraper conveyor for storage to solve the problems mentioned in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a grain scraper conveyor for storage.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A grain scraper conveyor for storage, comprising a bracket, a transport frame is arranged above the bracket, one end of the transport frame is rotatably connected to the bracket, a bracket seat located on the upper side of the bracket is fixed to the lower side of the transport frame, sprockets are installed at both ends of the transport frame, corresponding chain belts are sleeved on the outer sides of the two sprockets, a plurality of fixed blocks are evenly fixed on the outer side of the chain belt, and a scraper is rotatably connected to the outer side of the fixed block;

[0007] Sliding seats are arranged on both sides of the scraper. Rack bars are fixed to the lower sides of both ends of each sliding seat. The rack bars slide left and right on the supporting seat. A spur gear is arranged between the two rack bars on the same side of the two sliding seats. The two spur gears are rotatably connected to the supporting seat. Tooth grooves corresponding to the spur gears are formed inside the rack bars. The two rack bars on the same side and the middle spur gear are all meshed;

[0008] Supporting plates are rotatably connected to the upper and lower parts of the left and right outer sides of the transport frame. Side plates that slide up and down are arranged on the outer sides of the sliding seats. A rotating bar block is arranged on the lower side of the side plate. The outer end of the rotating bar block is rotatably connected to the side plate. A sliding bar block is sleeved and slid on the inner end of the rotating bar block.

[0009] Preferably, the sliding seat slides on the supporting seat through the rack bars at both ends. A sliding groove corresponding to the rack bar is formed on the supporting seat, and a limiting block is arranged at the inner end of the rack bar.

[0010] Preferably, a main driving device connected to a sprocket is installed inside the transport frame, and a plug shaft is fixed to the other end of the transport frame. Sliding sleeves are sleeved and slid on both ends of the plug shaft.

[0011] Preferably, the two sliding sleeves are respectively转接 (should be 'rotatably connected') to the two sliding seats on both sides, and the outer ends of the sliding sleeves are fixedly connected to one ends of the corresponding rotating bar blocks on the outside.

[0012] Preferably, a sliding groove corresponding to the side plate is formed inside the sliding seat. A spring corresponding to the side plate is arranged in the sliding groove, and U-shaped limiting blocks are rotatably connected to one side of the two sliding seats.

[0013] Preferably, openings corresponding to the U-shaped limiting blocks are formed on the lower side of the outer end of the sliding bar block and on one side of the side plate, and a plurality of positioning grooves corresponding to the openings at the outer end of the sliding bar block are formed on the left and right of one side surface of the bracket.

[0014] Preferably, a torsion spring is arranged at the connection between the supporting plate and the transport frame, and a rotation limiting structure corresponding to the supporting plate is arranged on the transport frame, and the rotation angle is within a range of ninety degrees.

[0015] Preferably, inclined bottom pushes are fixed to the lower left and right of the front side of the scraper, and a torsion spring is arranged at the connection between the scraper and the fixed block.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present invention can be flexibly adjusted according to different grain transportation needs and scenarios. The transport frame can change its angle through the rotation connection with the bracket to adapt to the material handling needs in different environments. Whether on flat ground, ramps or special transportation paths, the scraper conveyor can maintain a good material scraping effect. The angle adjustment can also ensure that the contact between the scraper and the material is more precise, effectively improve the transportation efficiency, and avoid material dispersion or accumulation. By adjusting the angle of the transport frame, the material transportation path can also be optimized, and the stability and reliability of the system can be enhanced;

[0018] 2. The support plate and slide structure in the design of the present invention enable the scraper conveyor to have efficient storage and handling capabilities. The support plate can be automatically folded under the action of the torsion spring, and the slide and side plate structure facilitates space saving during transportation or storage of the equipment. Through these mechanized storage methods, the volume of the equipment can be greatly reduced, reducing the storage space occupied, making the machine easier to carry, and improving the overall efficiency and convenience of use of the equipment;

[0019] 3. In the process of scraper movement and angle adjustment, the stability of the equipment is effectively guaranteed. This stability not only ensures the smoothness of the transportation process, but also avoids mechanical damage or material loss caused by external interference. The rapid deployment mechanism enables the equipment to quickly respond to the needs of grain transportation, improve work efficiency, adapt to the rapidly changing working environment, and reduce startup time and manual intervention.

[0020] In summary, the present invention has significant advantages in multi-angle adjustment, convenient storage and transportation, rapid deployment and automated operation. Its flexible angle adjustment, simple storage and transportation, rapid deployment mechanism and efficient automated operation design enable the equipment to adapt to a variety of complex storage environments and transportation needs. By enhancing the design of stability and safety, the working reliability of the equipment is further improved and the maintenance difficulty is reduced. This scraper conveyor is suitable for modern warehousing and logistics environments, can improve the efficiency and safety of grain transportation, reduce labor costs, and enhance the adaptability and convenience of the equipment.

Specific implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Referring to Figure 1-8 , a grain scraper conveyor for warehousing includes a bracket 1. Above the bracket 1 is provided a transport frame 2. One end of the transport frame 2 is rotatably connected to the bracket 1. Below the transport frame 2 is fixed a supporting seat 19 located above the bracket 1. At both ends inside the transport frame 2 are installed sprockets 18. A corresponding chain belt 6 is sleeved outside the two sprockets 18. A plurality of fixing blocks 8 are evenly fixed on the outside of the chain belt 6. A scraper 5 is rotatably connected to the outside of the fixing block 8. An active driving device connected to one sprocket 18 is installed inside the transport frame 2. The structure of the two sprockets 18 and the supporting chain belt 6 inside the transport frame 2, under the drive of the active driving device, through the scraper 5 fixed on the outside of the chain belt 6, forms a grain scraper transport mechanism to perform scraper transport on grain particles;

[0032] Furthermore, referring to Figure 2 , 5Slides 3 are provided on both sides of the scraper 5, racks 16 are fixed on the lower sides of both ends of the slides 3, and the racks 16 slide left and right on the bracket 19. A spur gear 17 is provided between the two racks 16 on the same side of the two slides 3. The two spur gears 17 are rotatably connected to the bracket 19. The inner side of the rack 16 is provided with a tooth groove corresponding to the spur gear 17. The two racks 16 on the same side are meshed with the middle spur gear 17. The slide 3 slides on the bracket 19 through the racks 16 at both ends. The bracket 19 is provided with a sliding groove corresponding to the rack 16. The inner end of the rack 16 is provided with a corresponding limit block, the outer side of the slide 3 is provided with a side plate 4 that slides up and down, the slide 3 is provided with a slide groove corresponding to the side plate 4, and the slide groove is provided with a spring corresponding to the side plate 4. The slide 3 on one side is moved outward, and the engagement of the racks 16 on both sides and the corresponding spur gears 17 is driven to drive the slide 3 on the other side to move outward. The slide 3 moves outward and unfolds, and the outer side plate 4 moves upward under the action of the spring elastic force, forming a left and right encirclement of the scraper 5 to prevent the scraped and transported materials from being scraped to the two outer sides;

[0033] Furthermore, referring to Figure 6 , 7 , the left and right outer sides of the transport frame 2 are rotatably connected with the support plates 15, and the connection between the support plates 15 and the transport frame 2 is provided with a torsion spring, and the transport frame 2 is provided with a rotation limiting structure corresponding to the support plates 15, and the rotation angle is within the range of ninety degrees. After the above-mentioned slide 3 moves outward, the support plate 15 loses the restriction of the slide 3, and is acted on by the torsion spring to rotate outward by ninety degrees, forming a bottom support for the upper and lower scrapers 5. At this moment, when the support plate 15 is flattened, the slide 3 is pushed inward, so that the slide 3 plays a supporting and limiting role on the upper side outward rotating horizontal support plate 15;

[0034] Furthermore, referring to Figure 4 , 8 , the scraper 5 is fixed with an inclined bottom pusher 20 on the left and right lower sides of the front side, and a torsion spring is provided at the transition between the scraper 5 and the fixed block 8. The torsion spring makes the scraper 5 straight without external interference. When the above-mentioned support plate 15 is rotated outward and horizontal, it supports the upper scraper 5, and through the transition of the outer arc surface of the inclined bottom pusher 20, the outward-rotating horizontal support plate 15 can squeeze and rotate several scrapers 5 vertically, and then cooperate with the sprocket belt mechanism to form the purpose of grain scraper transportation. The setting of the inclined bottom pusher 20 is also conducive to the scraper pushing material, ensuring the scraping of the material on the surface of the unfolded support plate 15;

[0035] Furthermore, referring to Figure 2 , 4, 6. A rotating bar block 10 is provided on the lower side of the side plate 4. The outer end of the rotating bar block 10 is rotatably connected to the side plate 4. A sliding bar block 11 is sleeved and slid on the inner end of the rotating bar block 10. And a plug shaft 12 is fixed at the other end of the transport rack 2. Sliding sleeves 13 are sleeved and slid on both ends of the plug shaft 12. The two sliding sleeves 13 are respectively connected and rotated in the two side sliding seats 3. And the outer end of the sliding sleeve 13 is fixedly connected to one end of the corresponding rotating bar block 10 on the outside. And a U-shaped limiting block 9 is rotatably connected to one side of each of the two sliding seats 3. Openings 14 corresponding to the U-shaped limiting block 9 are provided on the lower side of the outer end of the sliding bar block 11 and on one side of the side plate 4. And a plurality of positioning grooves 7 corresponding to the openings 14 at the outer end of the sliding bar block 11 are provided on the left and right of one side surface of the bracket 1. Before the above-mentioned sliding seat 3 moves outwards, it is necessary to rotate the U-shaped limiting block 9 on the sliding seat 3 so that the structures of the outer side plate 4 and the sliding bar block 11 lose the limitation of the U-shaped limiting block 9;

[0036] Furthermore, the structures of the two rotating bar blocks 10 move outwards together with the sliding seat 3 under the cooperation of the corresponding plug shaft 12 and the sliding sleeve 13. However, the structure of the rotating bar block 10 still maintains the rotational connection relationship with the transport rack 2. And since the transport rack 2 is rotatably connected to the bracket 1, the transport rack 2 on the bracket 1 can be rotated to adaptively adjust the angle of the scraper transport mechanism to match the specific material transport scenario and requirements. After determining the angle, under the support structure formed by the rotating bar block 10 and the sliding bar block 11, the transport rack 2 with the changed angle is stably supported. The specific operation is to push the sliding bar block 11 towards the rotating bar block 10 until the sliding bar block 11 and the rotating bar block 10 are combined, and then rotate the rotating bar block 10 downwards. Through the opening 14 at the lower end of the sliding bar block 11, it is matched with the corresponding positioning grooves 7 on both side surfaces of the bracket 1 to form a stable support for the upper transport rack 2.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
