Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a warehouse loading and transfer system. Background Technology

[0002] Grain loading and unloading equipment is mechanical equipment used to transfer grain from one place to another. It is commonly used in agriculture, warehousing, and logistics industries to ensure efficient and smooth handling of grain during transportation and storage. Depending on the application scenario and operational requirements, grain loading and unloading equipment comes in various types. For example, belt conveyors are commonly used for horizontal or inclined transport of bulk grains. They transport grain from one place to another via a conveyor belt and are suitable for long-distance transport. They are also typically equipped with lifting mechanisms and conveyor belts for unloading grain from high places or large quantities of goods. These are commonly found in ports, warehouses, and other high-level grain unloading operations. Grain is unloaded from vehicles or containers using lifting platforms and tipping mechanisms, making them suitable for more compact operating spaces. The main function of grain loading and unloading equipment is to improve the efficiency, accuracy, and safety of grain transportation, loading, unloading, and storage processes.

[0003] However, existing grain loading and unloading equipment often encounters the following problems in use: In traditional grain loading and unloading processes, insufficient operational flexibility is a common issue, leading to low loading and unloading efficiency, especially when dealing with different types of bulk grain trucks. Firstly, bulk grain trucks vary in design and structure; some are taller and wider, or have special inlet and outlet ports. This requires the loading and unloading equipment to be able to adjust accordingly to the specific truck structure. However, most traditional grain loading and unloading equipment uses a fixed design and lacks flexible adjustment capabilities. This makes it difficult to guarantee the loading and unloading volume between the equipment and the bulk grain truck during each operation, easily leading to overloading or over-weighting of the bulk grain trucks. Utility Model Content

[0004] The main purpose of this utility model is to provide a loading and transfer system for grain out of warehouses, so as to effectively solve the problem mentioned in the background art that most of the existing traditional equipment adopts a fixed design, which easily leads to overloading or overweight of bulk grain trucks.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] Outbound loading and transfer system, including:

[0007] Support frame;

[0008] A grain storage hopper, which is installed on the support frame;

[0009] A fixing frame is fixedly installed on one side of the grain storage hopper;

[0010] Two sets of steering bases are located on one side of the grain storage hopper and extend in the direction of extension. The two sets of steering bases are movably mounted on the fixed frame.

[0011] Two sets of linkage mechanisms are provided, and the two sets of linkage mechanisms are configured one-to-one with the two sets of steering bases;

[0012] The first screw conveyor is installed at one end at the discharge end of the bottom of the grain storage hopper, and the first screw conveyor is connected to one of the two sets of linkage mechanisms.

[0013] The second screw conveyor is installed at one end on the top surface of the grain storage hopper and is connected to another set of linkage mechanisms.

[0014] The two sets of linkage mechanisms also include:

[0015] A lifting cylinder, the bottom end of which is movably mounted on the steering base;

[0016] A support rod, which is longitudinally mounted on any one of the steering bases;

[0017] A linkage rod, one end of which is movably connected to the top of a support rod, and the output end of the lifting cylinder is movably connected to the body of the linkage rod.

[0018] Also includes:

[0019] Guardrail, which is provided around the top surface of the grain storage hopper;

[0020] A ladder, which is installed on one side of the grain storage hopper;

[0021] A viewing window is provided on the outer surface of the grain storage hopper;

[0022] Flatbed truck, the support frame is mounted on the flatbed truck;

[0023] An adjustment port is provided on either of the two sets of steering bases;

[0024] A fixing rod, which passes through the adjustment port;

[0025] Nut, which is threadedly connected to the fixing rod.

[0026] Both the first and second screw conveyors are connected to their corresponding linkage rods by straps.

[0027] The two sets of steering bases are arranged symmetrically with the cross-section of the grain storage hopper as the axis.

[0028] The adjustment port is arc-shaped.

[0029] The adjustment ports are set up in a one-to-one correspondence with the two sets of steering bases.

[0030] Compared with existing technologies, the beneficial effects of this utility model are as follows: The two sets of linked screw conveyors designed in this utility model, combined with an adjustable steering base and fixing frame, allow the equipment to flexibly adjust the angle and docking position of the conveyors according to the specific conditions of the bulk grain truck (such as load, volume, etc.). This design greatly improves the accuracy and efficiency of grain loading and unloading. Through the adjustable steering base and linkage mechanism, the equipment can switch between two different screw conveyors to suck or transport grain from loaded bulk grain trucks according to their different sizes and load conditions, preventing vehicle overloading.

[0036] 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.

[0037] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] like Figure 1-3 As shown, the outbound loading and transfer system includes: a support frame 1, a grain storage hopper 2, a fixed frame 3, two sets of steering bases 4, two sets of linkage mechanisms 5, a first screw conveyor 6, and a second screw conveyor 7. The grain storage hopper 2 is mounted on the support frame 1, and the fixed frame 3 is fixedly mounted on one side of the grain storage hopper 2. The two sets of steering bases 4 are located on one side of the grain storage hopper 2 and are movably mounted on the fixed frame 3. The two sets of linkage mechanisms 5 are correspondingly arranged with respect to the two sets of steering bases 4. The two sets of steering bases 4 are symmetrically arranged about the cross-section of the grain storage hopper 2. The movable function of the steering bases allows for flexibility in operation, especially when adjusting the connection between the conveyor and the bulk grain truck. Precise connection can be achieved by rotating the bases, ensuring smooth and accurate grain transport. Considering that the steering bases need to withstand large torques, alloy steel or cast iron is used to ensure sufficient strength and stability. The moving parts of the steering bases should be lubricated to reduce friction and prevent wear. For cylinders in the linkage mechanism, it is recommended to use high-strength aluminum alloy or engineering plastics, which can reduce weight and ensure durability.

[0039] In this embodiment, one end of the first screw conveyor 6 is installed at the discharge end of the bottom of the grain storage hopper 2, and the first screw conveyor 6 is connected to one of the two sets of linkage mechanisms 5. One end of the second screw conveyor 7 is installed on the top surface of the grain storage hopper 2, and the second screw conveyor 7 is connected to the other set of linkage mechanisms. Both the first screw conveyor 6 and the second screw conveyor 7 are tied to their corresponding linkage rods 53 with straps. The first screw conveyor 6 and the second screw conveyor 7 are used for grain input and output, respectively. During operation, the two sets of screw conveyors coordinate their operation through the linkage mechanism to complete the grain transport from the grain storage hopper 2 to the bulk grain truck, or from the bulk grain truck to the grain storage hopper 2. The first screw conveyor 6 mainly serves the lighter-loaded bulk grain trucks, while the second screw conveyor 7 is mainly used for the heavier-loaded bulk grain trucks. This allows for flexible switching between different screw conveyors for loading and unloading grain according to the load of the bulk grain truck, ensuring the efficiency and safety of grain transportation.

[0040] In the above embodiment, the two sets of linkage mechanisms 5 further include: the bottom end of the lifting cylinder 51 is movably mounted on the steering base; the support rod 52 is longitudinally mounted on any set of steering bases; one end of the linkage rod 53 is movably connected to the top end of the support rod 52; and the output end of the lifting cylinder 51 is movably connected to the rod body of the linkage rod 53. This ensures that the two screw conveyors can operate flexibly under different conditions. The linkage mechanism adjusts the screw conveyor through the lifting cylinder 51, ensuring that it can be raised to a suitable angle. Furthermore, by rotating the adjusting nut 14, the screw conveyor can be stably fixed in the required position, avoiding the impact of external factors such as vibration on operation.

[0041] In this invention, guardrail 8 is installed around the top edge of the grain storage hopper 2, ladder 9 is installed on one side of the grain storage hopper 2, viewing window 10 is opened on the outer surface of the grain storage hopper 2, support frame 1 is installed on flatbed trolley 11, and adjustment port 12 is opened on either of the two sets of steering bases 4. The adjustment port 12 is arc-shaped and corresponds one-to-one with the two sets of steering bases 4. The adjustment port 12 is used to adjust the range of motion of the two sets of steering bases 4, thereby controlling the rotation angle of the steering bases and ensuring that the screw conveyor can dock with the cargo box of the bulk grain truck. Fixing rod 13 passes through the adjustment port 12, and nut 14 is threadedly connected to fixing rod 13. Fixing rod 13 and nut 14 are used to fix the steering base, ensuring that the screw conveyor does not shift position during operation and ensuring the accuracy and stability of grain conveying.

[0042] It should be noted that, in the use of the outbound loading and transfer system designed in this utility model, if the bulk grain truck is overloaded, the flatbed truck 11 is started, and the flatbed truck 11 transports the entire transfer device to the side of the bulk grain truck. The operator can climb to the top of the grain storage hopper 2 via the ladder 9, and start the linkage mechanism corresponding to the second screw conveyor 7. The lifting cylinder 51 is started, and the output end of the lifting cylinder 51 pushes the linkage rod 53 to lift the angle. The lifting of the linkage rod 53 drives the second screw conveyor 7 to lift. Then, the nut 14 is loosened. After the nut 14 is loosened, the two sets of steering bases 4 can rotate flexibly. The steering base corresponding to the second screw conveyor 7 is manually rotated so that the second screw conveyor 7 is pushed above the cargo box of the bulk grain truck. The nut 14 is then tightened to fix it, and the second screw conveyor 7 is started. The second screw conveyor 7 will transport the grain in the bulk grain truck to the connected grain storage hopper 2 for storage, and the load of the bulk grain truck will be reduced. If a lighter-loaded bulk grain truck is subsequently encountered, the linkage mechanism corresponding to the first screw conveyor 6 can be activated to lift the first screw conveyor 6. The corresponding steering base can then be adjusted, and once it reaches above the cargo box of the bulk grain truck, the second screw conveyor 7 will discharge the grain from the storage hopper 2 and transport it to the lighter-loaded bulk grain truck. This ensures that each bulk grain truck meets the specified load requirements.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
