Detailed ways

As shown in Figure 1, a specific embodiment of the present invention is proposed. The unpowered unloading gate based on the locking mechanism is the same as the existing structure: it includes a gate that controls the opening and closing of the hopper 10. The gate includes a horizontally arranged A square gate 1 is provided with gate slide rails 2 fixed on the hopper 10 on both sides of the gate 1. The two gate slide rails 2 can make the gate 1 slide along its straight line. In order to reduce the slippage of the gate, The friction between the rail 2 and the gate plate 1 facilitates the gate plate 1 to slide smoothly between the two gate plate slide rails 2. In this embodiment, the gate plate slide rail 2 includes two slide rail plates 2-1 arranged perpendicularly to the gate plate 1. , both slide rail plates 2-1 are evenly provided with several sets of rolling wheels 2-2, each set of rolling wheels 2-2 includes two rollers located on the upper and lower sides of the gate 1, and the gate 1 is provided with When the discharge port 3 matches the discharge port of the hopper 10, the gate 1 slides left and right along the two gate slide rails 2. When the discharge port 3 is directly opposite the discharge port of the hopper 10, as shown in Figure 5 As shown in Figure 6, the gate 1 is in the position of opening the hopper 10 for unloading. When the discharge port 3 is staggered with the discharge port of the hopper 10, as shown in Figure 6, the gate 1 is in the position of closing the hopper 10. At this time, the material cannot be unloaded; the difference is: a locking mechanism is provided on one side of the gate 1, and the locking mechanism includes a chute block 4 that penetrates the gate 1, and the chute block 4 passes from the gate 1 The upper surface vertically penetrates to the lower surface. As shown in Figure 2, the chute 5 is arranged vertically with the gate 1, and a cube-shaped chute 5 is provided in the chute block 4. The chute 5 There is a locking part 6 inside. The locking part 6 includes a locking frame 6-1 located outside the chute 5 and with an open upper end. In this embodiment, the size of the locking frame 6-1 is larger than the size of the chute 5. , so that the lock frame 6-1 cannot slide in the chute 5. The top of the lock frame 6-1 is provided with a roller shaft 6-2, and the roller shaft 6-2 and the lock frame 6-1 form a closed It has a hollow square frame shape, and a roller 6-3 is set on the roller shaft 6-2. The bottom end of the lock frame 6-1 is provided with a lock connecting block 6- that can slide up and down in the chute 5. 4. In this embodiment, by setting the size of the lock connection block 6-4 to be smaller than the size of the chute 5, the lock connection block 6-4 can slide up and down in the chute 5, and in order to ensure that the lock frame 6-1 is in contact with the chute 5. The connection of the lock connection block 6-4 is stable. In this embodiment, the lock frame 6-1 and the lock connection block 6-4 are integrally manufactured. The bottom end of the lock connection block 6-4 is also provided with a The locking movable block 6-5 slides up and down in the chute 5, as shown in Figure 4. The size of the locking movable block 6-5 is smaller than the size of the chute 5. In this embodiment, the locking movable block 6-5 is provided with The size is the same as that of the lock connection block 6-4. Since the roller shaft 6-2 is not fixed, when the lock part is not subjected to external force, the lock part will slide down in the chute 5 under its own gravity. , since the size of the locking frame 6-1 is larger than the size of the chute 5, the locking member slides down in the chute 5 until the bottom end of the locking frame 6-1 is stuck above the chute 5. At this time, the locking The position where the component is only affected by its own gravity is also the lowest position. The locking mechanism also includes a locking frame embedded block 8 that is fixed on the hopper 10 and can be embedded in the locking frame 6-1. The locking frame The embedded block 8 is vertically folded and its bottom end is inclined. When the lock frame embedded block 8 is embedded in the lock frame 6-1, if the bottom end of the lock movable block 6-5 is continuously subjected to pressure, it can Make the roller 6-3 go up along the inclined end of the lock gate frame embedded block 8 until it reaches the right-angled end, as shown in Figure 6. At this time, the gate 1 closes the hopper 10 to stop unloading; the lower surface of the gate 1 A fixed contact block 9 is provided on the side away from the locking member 6, as shown in Figure 3, and the bottom end of the fixed contact block 9 is located on the same plane as the lowest end of the locking member 6 under its own gravity. , then a strong force acts on the fixed contact block 9 to make the gate plate 1 slide left and right along the gate slide rail 2. This embodiment uses the material receiving car 11 to touch the fixed contact block 9, and the material receiving car provided in this embodiment 11 includes the car body and the material receiving tank located on the car body. The material receiving tank can touch the bottom end of the fixed contact block 9 and the locking movable block 6-5, and the material receiving tank can make the gate plate 1 follow. The receiving truck travels a certain distance synchronously.

The gate lock movable block 6-5 is hinged at the bottom end of the gate lock connection block 6-4, so the gate lock movable block 6-5 can rotate and swing around the gate lock connection block 6-4, and the lower surface of the gate plate 1 The other side of the gate and located outside the chute 5 is provided with a lock limit block 7. The lock limit block 7 is used to limit the swing of the lock movable block 6-5 along the direction of the lock limit block 7, effectively Prevent the locking part 6 from slipping from the locking frame embedded block 8 under the action of external force (such as equipment vibration), so that the material receiving truck touches the locking movable block when driving to receive materials, causing the gate plate to slide and open the hopper, causing The material is wasted and the one-way function of the locking member 6 can be locked but cannot be opened.

When the present invention is used: the non-powered unloading valve is installed on the hopper 10 of the silo as shown in Figure 1, and the hopper 10 is generally in a closed state, as shown in Figure 6; when unloading is required, the receiving truck 11 moves along the figure When walking in the direction of the arrow in 6, if the locking part 6 is suspended on the locking frame embedded block 8, the material receiving vehicle 11 cannot touch it. If the locking part 6 slips from the locking frame embedded block 8 under the action of external force, the material receiving vehicle When the car 11 travels below the locking movable block 6-5, the material receiving tank touches the locking movable block 6-5 and causes it to rotate and swing in the driving direction around the locking connecting block 6-4. Due to the locking activity Block 6-5 is hinged below the lock connection block, so it will not produce a horizontal force on the lock part 6, and thus cannot drive the gate 1 to slide along the two gate guide rails 2, and the material receiving car 11 continues to move forward. When driving, it comes into contact with the fixed contact block 9, so that the gate 1 is driven by the fixed contact block 9 and moves synchronously along the two gate slide rails 2 with the material receiving car 11, and at the same time drives the rollers 6-3 along the locking frame. The inclined end of the embedded block 8 slides down, and the lock connection block 6-4 and the lock movable block 6-5 also move downward simultaneously in the chute 6-3 until the roller 6-3 breaks away from the lock frame embedded block 8. The material receiving truck 11 stops at the material receiving place. At this time, the gate 1 also stops and the discharge port 3 on it is directly below the material port of the hopper 10. As shown in Figure 5, the hopper 10 starts to unload materials; the material is to be received. When the vehicle 11 is full of materials, the material receiving vehicle 11 backs out along the original path, in the direction of the arrow in Figure 5. When the material receiving tank is located below the locking movable block 6-5, the material receiving tank touches the locking movable block. 6-5 will cause it to rotate and swing around the lock gate connection block 6-4 in the backward direction of the material receiving truck 11. However, due to the action of the lock gate limit block 7, the lock gate movable block 6-5 cannot rotate and swing. As the material receiving truck 11 moves synchronously, it will continue to contact the locking movable block 6-5. On the one hand, it drives the gate plate 1 to move synchronously. On the other hand, the locking connection block 6-4 and the locking movable block 6-5 are slid together. The groove 6-3 also moves upward synchronously. As the material receiving truck 11 retreats from the original path, the locking member 6 also moves synchronously and also moves upward until the inclined end of the locking frame embedded block 8 is embedded in the locking frame 6-3. 1, the roller 6-3 moves up along the inclined end of the lock frame embedded block 8 under the action of the material receiving tank, and stops at a right angle. At this time, the lock movable block 6-5 also moves up synchronously until it matches the The receiving tank is detached, and the gate 1 also stops moving. At this time, the discharge port 3 is staggered with the material port of the hopper 11, as shown in Figure 6, and the hopper stops discharging. The entire unloading and closing process is started by the movement of the receiving truck 11. No additional drive is required to avoid normal unloading due to malfunctions. It is not only mechanically automatic, but also energy-saving and environmentally friendly.

Of course, the above is only a detailed description of the preferred specific embodiments of the present invention in conjunction with the accompanying drawings, and is not intended to limit the implementation scope of the present invention. All equivalent changes based on the principles, structures and structures of the present invention should be covered by this invention. within the scope of protection of the invention.
