Description

Technical Field

[0001] This disclosure relates to the field of underground ore chute discharge, specifically to an ore discharge device. Background Technology

[0002] In underground ore chute operations, existing ore chute openings commonly use wooden plank ore-blocking devices, which have significant limitations in actual operation. During ore chute operations, workers must manually pry open the wooden planks with steel bars to allow ore to flow out smoothly. This process relies on manual labor, increasing both the intensity of work and the preparation time for each ore chute operation. Furthermore, when it is necessary to close the ore chute and stop ore chute operations, the two wooden planks must be repositioned to block the ore flow. This operation also relies on manual alignment and securing, which is not only time-consuming and labor-intensive but also often results in situations where the closure cannot be completed quickly. This leads to continuous ore outflow from the ore chute, exceeding the controlled ore discharge rate, and consequently causing ore accumulation and affecting subsequent processes, posing safety and production risks. Utility Model Content

[0003] The purpose of this disclosure is to provide a ore discharge device that can at least partially solve the technical problems existing in the related art.

Detailed Implementation

[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the outline of the corresponding component itself; directional terms such as "upper," "lower," "horizontal," and "vertical" are defined based on the usage habits of the heaters provided in this disclosure. Specifically, please refer to... Figure 1 In the diagrams shown, the direction indicated by the Z-arrow is upward, and vice versa; additionally, the X-direction indicates the horizontal direction, and the Z-direction indicates the vertical direction. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not indicate sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements.

[0020] Reference Figure 1 This disclosure provides a ore discharge device, which may include a chute 1, a baffle 2, and a drive assembly 3. The chute 1 may be fixed on a ore pass 7 and includes a second ore outlet 11 with its opening facing horizontally. The chute 1 may communicate with a first ore outlet of the ore pass 7. In the embodiment provided in this disclosure, the ore pass 7 extends generally vertically, and the opening of the first ore outlet faces downward. When the ore is transported from top to bottom to the first ore outlet in the ore pass 7, the ore can be received by the chute 1 because the opening of the second ore outlet 11 faces horizontally. After being received by the chute 1, the ore can be discharged to a mine car (not shown in the figure) through the second ore outlet 11 of the chute 1. The baffle 2 may be disposed at the edge of the second ore outlet 11 of the chute 1 and hinged to the trough plate 12 of the chute 1. The baffle 2 is configured to swing back and forth relative to the end face of the second ore outlet 11 to discharge or block ore. Specifically, when the baffle 2 is located at the end face of the second outlet 11, it can block the second outlet 11, thereby temporarily storing the ore in the chute 1 and blocking the outflow of the ore. When ore discharge is required, the baffle 2 is rotated and moved away from the end face of the second outlet 11, so that the second outlet 11 is fully open, and the ore in the chute 1 can flow smoothly out along the second outlet 11, meeting the requirements of ore discharge. The drive component 3 can be used to drive the baffle 2 to swing back and forth, eliminating the need for manual operation of the baffle 2 at close range. This reduces the labor intensity of personnel and avoids the safety risks caused by close contact between personnel and the second outlet 11 of the chute and the flowing ore. In addition, the drive component 3 can be connected to the baffle 2 for transmission, so as to adjust the time for which the baffle 2 is held in the current position according to the ore discharge requirements, thereby ensuring control of the ore discharge rate.

[0021] Through the above technical solution, using the ore discharge device provided in this disclosure, when the ore is discharged through the chute 7, the drive component 3 drives the baffle 2 to move back and forth, so as to realize the temporary storage and discharge of the ore in the chute 1, thereby realizing precise control of ore discharge and ore blocking, simplifying the operation process, ensuring controllable ore discharge and timely and efficient ore blocking, and effectively solving the problems of time-consuming and labor-intensive operation and untimely closure of the mine.

[0022] Reference Figure 1 The baffle 2 has a U-shaped cross-section along the horizontal direction with its opening facing the second ore outlet 11. This U-shaped structure can laterally surround the outside of the chute 1. The baffle 2 can include two first side plates 21 and a second side plate 22 connected between the two first side plates 21. The two first side plates 21 can be hinged to the two trough plates 12 of the chute 1, respectively. The second side plate 22 can be connected between the two first side plates 21 along a direction perpendicular to the ore output direction to block the second ore outlet 11. By hinged between the baffle 2 and the trough plates 12, the overall structure of the baffle 2 can swing relative to the second ore outlet 11. Thus, when ore needs to be discharged, by rotating the first side plates 21, the entire baffle 2 can completely avoid the second ore outlet 11. When ore needs to be blocked, by rotating the first side plates 21, the entire baffle 2 can completely block the position of the second ore outlet 11 and form a semi-enclosed structure with the second side plate 22 at the opening of the second ore outlet 11, thereby effectively improving the reliability of ore blocking.

[0023] like Figure 1 As shown, the width of the first side plate 21 gradually increases from the side furthest from the second side plate 22 toward the side plate 22. This design ensures that when the baffle 2 closes to block ore, the contact area between the first side plate 21 and the second ore outlet 11 gradually increases with the closing action. This, combined with the semi-enclosed structure, enhances the sealing and reduces ore leakage. Simultaneously, the narrower width of the baffle 2's opening side reduces interference between the first side plate 21 and the trough plate 12 or the ore when the first side plate 21 swings or discharges ore, ensuring smooth opening and closing while maintaining reliable ore blocking.

[0024] refer to Figure 1 The ore discharge device may also include a pin 41 fixed on the trough plate 12, and the first side plate 21 is provided with a hole 42 through which the pin 41 passes. In this way, the pin 41 forms the rotation fulcrum of the first side plate 21, allowing the first side plate 21 to swing around the axis of the pin 41, thereby driving the entire baffle 2 to reciprocate relative to the second ore outlet 11. This provides stable structural support for complete avoidance during ore discharge and precise alignment during ore blocking, ensuring the smoothness and reliability of the opening and closing action of the baffle 2. At the same time, this hinged structure is simple and the connection is stable, and it can effectively withstand the radial force brought by the impact of ore.

[0025] refer to Figure 1The drive assembly 3 may include a drive component (not shown in the figure) for outputting driving force and a transmission rod 31 connected between the drive component and the baffle 2. The transmission rod 31 can be used to drive the baffle 2 to swing forward around the pin 41 during ore discharge and to drive the baffle 2 to swing backward around the pin 41 during ore blocking. This can precisely control the opening and closing of the baffle to meet the needs of ore discharge and ore blocking, avoid close-range manual operation, improve work efficiency and safety, and simplify the layout and maintenance of the drive assembly 3. It should be noted that the forward swing can be... Figure 1 The counterclockwise oscillation shown in the diagram can be... Figure 1 The pointer swings clockwise in the direction shown in the figure. In the embodiment provided in this disclosure, the transmission rod 31 can extend along the output direction perpendicular to the ore, and one end is fixedly connected to the second side plate 22 of the baffle 2 to transmit driving force. The other end of the transmission rod 31 can extend beyond a safe distance and can be connected to the drive motor. Alternatively, the operator can manually move the transmission rod 31 up and down, ensuring work efficiency during material feeding and eliminating risks during operation.

[0026] Reference Figure 1 The drive assembly 3 may also include a chain 32, which may be made of metal and can be fixedly connected between the second side plate 22 and the top wall 8 of the mine passage. This provides reliable limiting of the swing stroke of the baffle 2, preventing damage from excessive swinging and collision with the chute 1 or other components. It also provides flexible support for the baffle 2 during ore discharge, preventing unexpected shaking due to ore impact. Furthermore, it ensures smooth opening and closing of the baffle 2, further enhancing the overall stability and safety of the device.

[0027] like Figure 1 The ore discharge device may also include a weight block 5 fixed on the second side plate 22. This allows the baffle 2 to have sufficient stability when blocking ore with the help of the gravity of the weight block 5. It can not only effectively resist the impact of ore and prevent the baffle 2 from being pushed open, but also assist the baffle 2 to quickly reset and close without external driving force, simplifying the ore blocking operation and improving the timeliness of ore blocking.

[0028] Reference Figure 1 The chute 1 may include a guide plate 13 connected between two chute plates 12. The guide plate 13 gradually slopes downward along the output direction of the ore, thereby forming a smooth ore conveying slope to improve the ore discharge efficiency.

[0029] In the embodiments provided in this disclosure, the chute 1 and the baffle 2 can be made of metal respectively, and the chute 12 is welded and fixed to the ore pass 7 to ensure sufficient reliability in the connection between the components. When the ore discharge device includes the aforementioned transmission rod 31 and load block 5, the transmission rod 31 and the load block 5 can be made of metal and welded to the second side plate 22 to ensure the transmission effect and the stability of the connection between the components.

[0030] refer to Figure 1 The ore discharge device may also include a connecting rod 6 made of metal. One end of the connecting rod 6 is welded to the trough plate 12, and the other end is welded to the wall of the chute 7 upstream of the first ore outlet. By setting the fixing point of the connecting rod 6 on the relatively solid wall of the chute 7 and arranging the connecting rod 6 in the less stressed area upstream of the first ore outlet, the stability of the connection between the components and the rigidity and stability of the overall structure can be significantly improved, effectively resisting the impact of the ore, and thus ensuring the connection strength between the trough 1 and the chute 7.
