The non-powered discharge gate is provided with a fixed contact block and the lock gate mechanism, and the contact block is touched by a receiving vehicle when the receiving vehicle drives to receive materials and backs to unload materials, so that the gate plate slides on the gate plate sliding rail, and then the discharge and closing of the hopper are realized. The non-powered discharge gate changes the existing discharge mode driven by an additional drive, avoids the interruption of the discharge caused by the failure of the additional drive, ensures the normal operation of the hopper, and saves energy and protects the environment without the additional drive. In addition, the non-powered discharge gate has the advantages of simple structure, easy manufacturing and good practicability, and is especially suitable for the hopper with high material temperature.

Description

Technical Field

[0001] This invention relates to a discharge gate, specifically a non-powered discharge gate based on a locking mechanism. Background Technology

[0002] The unloading gate is installed on the hopper discharge port of the silo and is used to open or close the hopper. Figure 1 Prajna Figure 7 As shown, a hopper is included in the hopper. The hopper's opening is equipped with a gate that controls its opening and closing. The gate includes a gate rail fixed to the hopper and a gate plate that can move along the rail. The gate plate is driven by a drive device fixed to the hopper, which is typically hydraulically driven, pneumatically driven, or electrically driven. When the drive device slides the gate to open the hopper, material falls from the hopper onto a receiving cart below. After the receiving cart is full, it reverses along the original path, and the drive device drives the gate to slide in the opposite direction to close the hopper. This type of unloading gate has the following drawbacks: regardless of whether it is hydraulically driven, pneumatically driven, or electrically driven, it is a wear-prone device that is prone to failure after a period of operation. Furthermore, if the material temperature in the hopper exceeds 200 degrees Celsius, the power drive cannot withstand such high temperatures and is more likely to be damaged. Therefore, during the unloading process from the hopper, unloading is easily interrupted. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a non-powered unloading gate based on a locking mechanism. This non-powered unloading valve, by setting a fixed contact block and a locking mechanism, utilizes the contact block and locking mechanism during the material receiving vehicle's movement to receive material and its reversing unloading to achieve left and right sliding of the gate on the gate rail, thereby realizing the unloading and closing of the hopper. This changes the existing method that requires an additional drive, avoiding unloading interruptions due to malfunctions in the additional drive and ensuring the normal operation of the hopper. Furthermore, it eliminates the need for an additional drive, saving energy and being environmentally friendly. In addition, this non-powered unloading valve has a simple structure, is easy to manufacture, and has good practicality, especially suitable for hoppers with high material temperatures.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] The non-powered unloading gate based on the locking mechanism is similar to existing structures in that it includes a gate for controlling the opening and closing of the hopper. The gate includes a horizontally arranged, square-shaped gate plate. Both sides of the gate plate are provided with gate plate slide rails fixed to the hopper, allowing the gate plate to slide linearly along these rails. The gate plate has an unloading port that matches the hopper's feed opening. The difference is that a locking mechanism is provided on one side of the gate plate. This locking mechanism includes a sliding block that penetrates the gate plate vertically from the upper surface to the lower surface. The sliding block has a cuboid-shaped groove within it, and a locking element is installed within the groove. The locking element includes a positioning... The locking mechanism includes a locking frame located outside the chute and open at the top. A roller shaft is located at the top of the locking frame, and a roller is fitted onto the roller shaft. A locking connecting block that can slide up and down within the chute is located at the bottom of the locking frame. A locking movable block that can also slide up and down within the chute is located at the bottom of the locking connecting block. The locking mechanism also includes a locking frame embedding block fixed to the hopper and embedded within the locking frame. The locking frame embedding block is vertically folded and its bottom end is inclined. A fixed contact block is located on the side of the lower surface of the gate plate away from the locking component, and the bottom end of the fixed contact block and the lowest point of the locking component under its own weight are located on the same plane.

[0006] As a preferred technical solution, in order to prevent the locking gate frame embedded block from slipping off under the action of external force, so that the receiving trolley touches the locking gate movable block when receiving materials, causing the gate plate to slide and the hopper to open, resulting in material waste, the locking gate component can lock but not open in one direction. The locking gate movable block is hinged to the bottom end of the locking gate connecting block, and a locking gate limiting block is provided on the other side of the lower surface of the gate plate and outside the slide groove. The locking gate limiting block is used to restrict the locking gate movable block from swinging along the direction of the locking gate limiting block.

[0007] Compared with the prior art, the present invention has the following advantages:

[0008] 1. This non-powered unloading valve uses a fixed contact block and a locking mechanism. When the receiving trolley moves to receive material and reverses to unload material, it contacts the contact block, allowing the gate to slide left and right on the gate rail. This enables the unloading and closing of the hopper, eliminating the need for an additional drive. This avoids interruptions in unloading due to malfunctions of the additional drive, ensuring the normal operation of the hopper. Furthermore, it eliminates the need for an additional drive, saving energy and being environmentally friendly. In addition, this non-powered unloading valve has a simple structure, is easy to manufacture, and is highly practical, especially suitable for hoppers with high material temperatures.

[0009] 2. The locking shaft movable block is hinged to the bottom end of the locking gate connecting block, and a locking gate limit block is also set to restrict the swing of the locking gate movable block in the other direction. This effectively prevents the locking gate frame embedded block from slipping off under the action of external force, so that when the material receiving car is receiving material, it touches the locking gate movable block, causing the gate plate to slide and the hopper to open, resulting in material waste. This realizes the one-way function of the locking gate that can lock but cannot open. Attached Figure Description

Detailed Implementation

[0019] like Figure 1The present invention presents a specific embodiment of a non-powered unloading gate based on a locking mechanism. Similar to existing structures, it includes a gate for controlling the opening and closing of the hopper 10. The gate includes a horizontally arranged square gate plate 1. Gate plate 1 has gate plate slide rails 2 fixed to the hopper 10 on both sides. The two gate plate slide rails 2 allow the gate plate 1 to slide linearly along them. To reduce the friction between the gate plate slide rails 2 and the gate plate 1 and facilitate smooth sliding between the two gate plate slide rails 2, this embodiment provides two slide rail plates 2-1 perpendicular to the gate plate 1. Several sets of rolling wheels 2-2 are evenly distributed on both slide rail plates 2-1. Each set of rolling wheels 2-2 includes two rollers on the upper and lower sides of the gate plate 1. The gate plate 1 has an unloading port 3 matching the material inlet of the hopper 10. When the gate plate 1 slides linearly left and right along the two gate plate slide rails 2, when the unloading port 3 is directly opposite the discharge outlet of the hopper 10, ... Figure 5 As shown, the gate 1 is in the position where the hopper 10 is open, allowing for material unloading. When the discharge port 3 is misaligned with the outlet of the hopper 10, as... Figure 6 As shown, the gate 1 is in the closed position of the hopper 10, at which time material cannot be discharged; the difference is that: a locking mechanism is provided on one side of the gate 1, and the locking mechanism includes a sliding block 4 that penetrates through the gate 1, the sliding block 4 vertically penetrating from the upper surface to the lower surface of the gate 1, as shown. Figure 2 As shown, the slide groove 5 is perpendicular to the gate plate 1, and a cuboid slide groove 5 is formed inside the slide groove block 4. A locking gate component 6 is provided inside the slide groove 5. The locking gate component 6 includes a locking gate frame 6-1 located outside the slide groove 5 and open at the top. In this embodiment, the size of the locking gate frame 6-1 is set larger than the size of the slide groove 5, preventing the locking gate frame 6-1 from sliding within the slide groove 5. A roller shaft 6-2 is provided at the top of the locking gate frame 6-1. The roller shaft 6-2 and the locking gate frame 6-1 form a closed, hollow square frame. A locking gate component is fitted onto the roller shaft 6-2. A roller 6-3 is provided. The bottom end of the gate frame 6-1 is provided with a gate connecting block 6-4 that can slide up and down within a slide groove 5. In this embodiment, the size of the gate connecting block 6-4 is set smaller than the size of the slide groove 5, allowing the gate connecting block 6-4 to slide up and down within the slide groove 5. To ensure a stable connection between the gate frame 6-1 and the gate connecting block 6-4, this embodiment sets the gate frame 6-1 and the gate connecting block 6-4 to be integrally manufactured. The bottom end of the gate connecting block 6-4 is provided with a gate movable block 6-5 that can also slide up and down within the slide groove 5. Figure 4As shown, the size of the locking brake movable block 6-5 is smaller than the size of the slide groove 5. In this embodiment, the size of the locking brake movable block 6-5 is the same as the size of the locking brake connecting block 6-4. Since the roller shaft 6-2 is not fixed, the locking brake will slide down in the slide groove 5 under its own weight when the locking brake is not subjected to external force. Since the size of the locking brake frame 6-1 is larger than the size of the slide groove 5, the locking brake will slide down in the slide groove 5 until the bottom end of the locking brake frame 6-1 is stuck above the slide groove 5. At this time, the locking brake is only subjected to its own weight, which is also its lowest position. The locking brake mechanism also includes a locking brake frame embedding block 8 fixed on the hopper 10 and can be embedded in the locking brake frame 6-1. The locking brake frame embedding block 8 is vertically folded and its bottom end is inclined. When the locking brake frame embedding block 8 is embedded in the locking brake frame 6-1, if the bottom end of the locking brake movable block 6-5 is continuously subjected to pressure, the roller 6-3 can move upward along the inclined end of the locking brake frame embedding block 8 until it reaches the right angle end. Figure 6 As shown, at this time, the gate 1 closes the hopper 10 and stops unloading; the lower surface of the gate 1 is provided with a fixed contact block 9 on the side away from the locking element 6, such as Figure 3 As shown, the bottom end of the fixed contact block 9 and the lowest end of the locking brake 6 under its own weight are located on the same plane. When a force is applied to the fixed contact block 9, the brake plate 1 can slide left and right along the brake plate slide rail 2. In this embodiment, the receiving cart 11 is used to touch the fixed contact block 9. The receiving cart 11 in this embodiment includes a cart body and a receiving tank on the cart body. The receiving tank can touch the bottom end of the fixed contact block 9 and the locking brake movable block 6-5. The receiving tank can make the brake plate 1 move synchronously with the receiving cart for a certain distance.

[0020] The locking gate movable block 6-5 is hinged to the bottom end of the locking gate connecting block 6-4, so the locking gate movable block 6-5 can rotate and swing around the locking gate connecting block 6-4. On the other side of the lower surface of the gate plate 1, and outside the slide groove 5, there is a locking gate limiting block 7. The locking gate limiting block 7 is used to limit the locking gate movable block 6-5 to swing along the direction of the locking gate limiting block 7, effectively preventing the locking gate component 6 from slipping off the locking gate frame embedded block 8 under the action of external force (such as equipment vibration), so that when the receiving trolley is receiving materials, it touches the locking gate movable block, causing the gate plate to slide and the hopper to open, resulting in the waste of materials. This realizes the one-way function of the locking gate component 6, which can lock the gate but cannot open it.

[0021] When using this invention: Place the non-powered unloading valve as follows... Figure 1 The hopper 10 is installed on the silo, and the hopper 10 is generally in the closed state, such as Figure 6 As shown; when unloading is required, the receiving trolley 11 moves along... Figure 6If the locking brake 6 is suspended on the locking brake frame insert 8 when the car travels in the direction of the middle arrow, the receiving trolley 11 cannot touch it. If the locking brake 6 slides off the locking brake frame insert 8 under external force, the receiving trolley 11 will touch the locking brake movable block 6-5 when it travels below the locking brake movable block 6-5. This will cause it to rotate and swing around the locking brake connecting block 6-4 in the direction of travel. Since the locking brake movable block 6-5 is hinged below the locking brake connecting block, it will not exert a horizontal force on the locking brake component 6, and thus cannot drive the brake plate 1 to slide along the two brake plate guide rails 2. The receiving trolley 11 continues to move forward and touches the fixed contact block 9, causing the brake plate 1 to move synchronously along the two brake plate slide rails 2 under the drive of the fixed contact block 9, and at the same time drive the roller 6-3 to slide down along the inclined end of the locking brake frame embedded block 8. The locking brake connecting block 6-4 and the locking brake movable block 6-5 also move synchronously downward in the slide groove 6-3 until the roller 6-3 disengages from the locking brake frame embedded block 8. When the receiving trolley 11 stops at the receiving point, the brake plate 1 also stops and its discharge port 3 is directly below the material port of the hopper 10. Figure 5 As shown, hopper 10 begins unloading; when receiving trolley 11 is full of material, receiving trolley 11 reverses along the original route, as... Figure 5 In the direction of the arrow, when the receiving tank is below the locking brake movable block 6-5, the receiving tank will touch the locking brake movable block 6-5 and cause it to rotate and swing around the locking brake connecting block 6-4 in the reverse direction of the receiving vehicle 11. However, due to the action of the locking brake limit block 7, the locking brake movable block 6-5 cannot rotate and swing. As the receiving tank moves synchronously with the receiving vehicle 11, it will continue to touch the locking brake movable block 6-5, which on the one hand drives the gate plate 1 to move synchronously, and on the other hand causes the locking brake connecting block 6-4 and the locking brake movable block 6-5 to move synchronously. -5 also moves upwards synchronously within the chute 6-3. As the receiving trolley 11 reverses along its original path, the locking brake 6 also moves synchronously and upwards until the inclined end of the locking brake frame embedding block 8 is embedded in the locking brake frame 6-1. Under the action of the receiving tank, the roller 6-3 moves upwards along the inclined end of the locking brake frame embedding block 8, stopping when it reaches a right angle. At this time, the locking brake moving block 6-5 also moves upwards synchronously until it disengages from the receiving tank, and the gate plate 1 also stops moving. At this time, the discharge port 3 and the material outlet of the hopper 11 are misaligned. Figure 6 As shown, the hopper stops unloading. The entire unloading and closing process is initiated by the movement of the receiving trolley 11, without the need for additional drive, thus avoiding the inability to unload normally due to malfunction. It is not only mechanically automated, but also energy-saving and environmentally friendly.

[0022] Of course, the above description of preferred embodiments of the present invention is only in conjunction with the accompanying drawings and is not intended to limit the scope of the present invention. All equivalent changes made in accordance with the principles, construction and structure of the present invention should be covered within the protection scope of the present invention.
