Detailed Implementation

[0022] Example 1

[0023] like Figure 1 - Figure 2 As shown, an adjustable grain truck safety unloading device includes a chain 1, a rope tensioner 2, and a safety rope 3 connected in series. The rope tensioner 2 is preferably a commonly used truck rope tensioner on the market. Under normal circumstances, the rope tensioner gradually winds the connected rope through a ratchet self-locking assembly to achieve the rope tightening effect. In this embodiment, the safety rope 3 is wound around the rope tensioner in the same direction as the ratchet rotation. Thus, the safety rope 3 can be gradually released by controlling the rotation of the ratchet, which is convenient to operate and safe and reliable. One end of the chain 1 is fixedly connected to the rope tensioner 2, and one end of the safety rope 3 is adjustablely wound around the rope tensioner 2. When the gap between the truck bed structure rod 9 and the truck bed is large, and the truck bed structure rod 9 has sufficient strength, The end of the chain 1 away from the rope tensioner 2 is directly wrapped around the truck bed structure rod 9 and then detachably connected to any loop of the chain 1 through fasteners such as safety buckles and shackles 8. Safety buckles are preferred for fastener 8 because they are easy to operate. By changing the position of the fastener 8 connected to the chain 1, the opening of the truck bed door 11 can be initially set. The end of the safety rope 3 away from the rope tensioner 2 passes through the rope tensioner 2 and is also detachably connected to the truck bed structure rod 9 through fasteners such as safety buckles and shackles 8. Since the chain 1 is in a taut state during the unloading process and cannot be adjusted, the safety rope 3 is gradually released through the rope tensioner 2 to adjust the opening of the truck bed door 11 during the unloading process, so as to gradually enlarge the unloading port 10.

[0024] The working principle of this utility model can be summarized as follows:

[0025] Before unloading, according to the required initial opening size of the unloading port 10, the end of the chain 1 away from the rope tensioner 2 is wrapped around the truck bed structure rod 9 on one side of the unloading port 10 and then detachably connected to the chain 1 at a suitable position through a safety buckle. The end of the safety rope 3 away from the rope tensioner 2 is passed through the rope tensioner 2 and then detachably connected to the truck bed structure rod 9 on the other side of the unloading port 10 through a safety buckle. Then the truck bed door 11 can be opened for unloading. Under the limitation of the chain 1 and the safety rope 3, the truck bed door 11 can only have a fixed opening. As unloading proceeds, the grain in the truck bed gradually decreases, and the safety rope 3 can be gradually released through the rope tensioner 2, thereby increasing the opening size of the unloading port 10.

[0026] Example 2

[0027] like Figure 3 - Figure 5 As shown, an adjustable grain truck safety unloading device differs from Embodiment 1 in that: when the gap between the truck bed structure rod 9 and the truck bed is small, and the chain 1 cannot pass through directly, or when the truck bed structure rod 9 is easily bent, the truck bed structure rod 9 is detachably connected to an installation component 4. The installation component 4 includes a U-shaped sleeve 401, which is detachably fitted onto the truck bed structure rod 9. The U-shaped sleeve 401 is provided with a limiting component 402 to prevent the installation component 4 from detaching from the truck bed structure rod 9. The limiting component 402 includes a positioning screw 4021 and a U-shaped sleeve. The sleeve 401 is provided with a threaded hole 4011 and a limiting hole 4012 for the positioning screw 4021 to pass through. A knob 4022 is fixedly connected to one end of the positioning screw 4021. First, the positioning screw 4021 is passed through the threaded hole 4011 and the limiting hole 4012 in sequence. Then, the positioning screw 4021 is directly threaded and fixed by the knob 4022, so that the U-shaped sleeve 401 is fixedly sleeved on the truck bed structure rod 9. The knob 4022 has a triangular structure and the adjacent corners are arc-shaped concave structures, which makes it easy for the user to rotate the knob 4022 and does not hurt the hands.

[0028] A pull rod 403 is fixedly connected to the U-shaped clamp 401. The pull rod 403 has a semi-circular structure, with both ends fixedly connected to the two ends of the U-shaped clamp 401. The end of the chain 1 away from the rope tensioner 2 is wrapped around the pull rod 403 and then detachably connected to any loop of the chain 1 through fasteners such as safety buckles and shackles 8. The end of the safety rope 3 away from the rope tensioner 2 passes through the rope tensioner 2 and is detachably connected to the pull rod 403 through fasteners such as safety buckles and shackles 8. The semi-circular structure of the pull rod 403 is conducive to evenly distributing the force on the pull rod 403 and to transferring the tension from both ends of the pull rod 403 to the U-shaped clamp 401. The force is distributed on the truck bed structure rod 9 through the U-shaped clamp 401, avoiding concentrated force on the truck bed structure rod 9 and causing deformation.

[0029] When the load inside the truck bed is large, the pressure of the grain discharged from the unloading port 10 on the truck bed door 11 will also increase. If only a single truck bed structural rod 9 is used to bear the tension, it is easy to deform. Therefore, in order to improve the safety of use, two sets of U-shaped sleeves 401 and limiting components 402 are provided to distribute the force to different truck bed structural rods 9 respectively.

[0030] Because the distance between the structural rods 9 of different truck beds varies, two sets of U-shaped clamps 401 are respectively fixedly connected to a sleeve 5 and an adjusting screw 6 to facilitate the installation and fixation of the installation component 4. The adjusting screw 6 is slidably inserted into the sleeve 5, and a fastening nut 7 is threaded through the adjusting screw 6. The fastening nut 7 has a U-shaped structure and is detachably threaded to the end of the sleeve 5 away from the U-shaped clamp 401. The distance between the two U-shaped clamps 401 is adjusted by changing the length of the adjusting screw 6 inserted into the sleeve 5. The adjusting screw 6 and the sleeve 5 are fixed by the fastening nut 7. At the same time, after unloading, all parts of the entire device can be disassembled and stored for easy carrying.

[0031] The working principle of this utility model can be summarized as follows:

[0032] Before unloading, first install the mounting components 4 on the truck bed structure rod 9. If the truck bed doors 11 are opened from the left and right, then install the two sets of mounting components 4 on the truck bed structure rod 9 of the open doors respectively. Specifically, the U-shaped sleeve 401 is coaxially sleeved on the structure, and then limited and fixed by the limiting component 402, so that it is firmly fixed together with the truck bed structure rod 9 to prevent it from falling off. The chain 1 and the safety rope 3 are connected to the pull rod 403 of the two sets of mounting components 4 respectively. Then the truck bed door 11 can be opened. Under the pull of the chain 1 and the safety rope 3, the opening of the truck bed door 11 becomes adjustable. By adjusting the rope tensioner 2, the safety rope 3 is gradually released, and the opening of the truck bed door 11 can be adjusted, thereby changing the unloading flow. After unloading, the safety rope 3 can be wound and stored by the rope tensioner 2.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
