Description

Technical Field

[0001] This utility model relates to the technical field of unloading devices for the rear door of grain trucks, and in particular to a carbon steel grain truck rear door unloading device. Background Technology

[0002] Grain trucks are vehicles specifically designed for transporting grain. At grain purchasing stations, carbon steel grain trucks can quickly collect the grain delivered by farmers and transport it to warehouses for storage. They also play an efficient role in transporting grain between warehouses. The grain truck rear door unloading device is a mechanical device installed at the rear door of the grain truck to unload grain from the rear of the truck. Its design aims to improve the efficiency and convenience of grain unloading and avoid the tediousness of manual loading and unloading. Existing grain truck rear door unloading devices, when in use, mostly use ordinary steel, which has problems such as insufficient strength, easy deformation, and poor corrosion resistance. Long-term use can easily lead to seal failure, causing grain leakage or moisture. Some devices use complex hydraulic or pneumatic systems, which are costly and difficult to maintain. They are not suitable for small and medium-sized grain transportation scenarios, and it is inconvenient to open the rear door for unloading in a stable and quick manner, which affects the efficiency of actual grain unloading. Utility Model Content

[0003] The purpose of this utility model is to provide a carbon steel grain truck rear door unloading device to solve the defects of existing grain truck rear door unloading devices that are inconvenient, unstable and quick to open the rear door for unloading.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a carbon steel grain truck rear door unloading device, including a small door profile; The outer wall of the small door profile is equipped with an upper carbon steel fixing plate, and a first fixing ear is fixedly connected to one side of the upper carbon steel fixing plate. A first pressing member is movably connected inside the first fixing ear. An adjusting rod is movably connected inside the first pressing member, and a second pressing member is movably connected to the outer wall of the adjusting rod. A second fixing ear is movably connected to the outer wall of the second pressing member, and a lower carbon steel fixing plate is fixedly connected to the outer wall of the second fixing ear.

[0005] Preferably, the first fixing ear forms a rotating structure with the first pressing member via a rotating shaft, and the first pressing member forms a rotating structure with the second pressing member via an adjusting rod, so that the first pressing member can rotate along the first fixing ear.

[0006] Preferably, the second pressing member forms a rotating structure with the second fixed ear via a rotating shaft, and the lower carbon steel fixing plate is movably connected to the small door profile, allowing the lower carbon steel fixing plate to be flipped open.

[0007] Preferably, the second pressing member has a limiting mechanism installed inside. The limiting mechanism includes a movable groove inside the second pressing member, a guide groove on the inner bottom wall of the movable groove, a positioning block movably connected inside the movable groove, a guide slider fixedly connected to the bottom of the positioning block, and a return spring fixedly connected to one side of the positioning block. The first pressing member has a positioning slot inside.

[0008] Preferably, the second pressing member forms a sliding structure with the positioning block through the movable groove, and the guide slider forms a sliding structure with the second pressing member through the guide groove, so that the positioning block can slide along the movable groove and be retracted into the second pressing member.

[0009] Preferably, the reset spring is located in the movable groove and is positioned between the second pressure member and the positioning block, so that the positioning block can be reset after being squeezed.

[0010] Preferably, the positioning block is engaged with the first pressing member through a positioning slot, and the end of the positioning block is hemispherical, so that one end of the positioning block can be engaged into the positioning slot for limiting.

[0011] The advantages of the rear door unloading device for carbon steel grain trucks provided by this utility model are as follows: The system consists of a small door profile, an upper carbon steel fixing plate, a first fixing ear, a first pressing member, a second pressing member, a second fixing ear, and a lower carbon steel fixing plate. By pulling the first pressing member, the first pressing member can rotate along the first fixing ear, causing the second pressing member to be pulled outward. This causes the second pressing member to rotate along the second fixing ear, which in turn causes the lower carbon steel fixing plate to flip open along the small door profile, thus facilitating the unloading of grain from the grain truck. Furthermore, since both the upper and lower carbon steel fixing plates are made of carbon steel, their resistance to deformation and corrosion can be improved, preventing grain from leaking or getting damp and extending their service life. The system consists of a first pressing component, a second pressing component, a lower carbon steel fixing plate, a limiting mechanism, and a positioning slot. By pulling the first pressing component, the outer wall of the first pressing component is pressed against the positioning block, causing the positioning block to retract into the second pressing component. When the lower carbon steel fixing plate is closed, the positioning block can be reset under the action of the return spring, and one end of it can be locked into the positioning slot for limiting. This facilitates the closing and limiting of the lower carbon steel fixing plate, further improving the sealing performance. Furthermore, the combined effect of the guide slider and the guide groove can improve the stability of the positioning block's sliding motion. Furthermore, since the adjusting lever is located above the first pressing member, the first pressing member acts as a force-saving lever, further improving the convenience of opening and closing the lower carbon steel fixing plate.

[0015] Please see Figures 1-5 The present invention provides a carbon steel grain truck rear door unloading device, including a small door profile 1.

[0016] Reference Figure 1 , Figure 2 and Figure 3 As shown, an upper carbon steel fixing plate 2 is installed on the outer wall of the small door profile 1. A first fixing ear 3 is fixedly connected to one side of the upper carbon steel fixing plate 2. A first pressing member 4 is movably connected inside the first fixing ear 3. An adjusting rotating rod 5 is movably connected inside the first pressing member 4. A second pressing member 6 is movably connected to the outer wall of the adjusting rotating rod 5. A second fixing ear 7 is movably connected to the outer wall of the second pressing member 6. A lower carbon steel fixing plate 8 is fixedly connected to the outer wall of the second fixing ear 7. The first fixing ear 3 and the first pressing member 4 form a rotating structure through a rotating shaft.

[0017] By pulling the first pressing member 4, the first pressing member 4 can rotate along the first fixed ear 3, and under the action of the adjusting rod 5, it can rotate along the second pressing member 6, causing the second pressing member 6 to be pulled outward, so that the second pressing member 6 can rotate along the second fixed ear 7, causing the lower carbon steel fixing plate 8 to flip open along the small door profile 1, so that the grain in the grain car can be unloaded. Since the material is carbon steel, the whole can be made lighter and the operation more convenient.

[0018] Reference Figure 2 , Figure 4 and Figure 5 As shown, a limiting mechanism 9 is installed inside the second pressing member 6. The limiting mechanism 9 includes a movable groove 91 inside the second pressing member 6. A guide groove 92 is provided on the inner bottom wall of the movable groove 91.
