Description

Technical Field

[0001] This utility model relates to the field of conveying machinery technology, and in particular to an anti-blocking device for a buried scraper conveyor and a buried scraper conveyor having the anti-blocking device. Background Technology

[0002] The buried scraper conveyor is a transportation device that uses a scraper chain moving inside a closed shell to transport bulk materials to a predetermined target. It has the advantages of small size, strong sealing, good rigidity, flexible process layout, convenient installation and maintenance, and the ability to feed and unload at multiple points.

[0003] Chinese utility model patent CN205802232U discloses a submerged scraper conveyor, comprising a head, a feed bin, a conveyor bin, a discharge bin, a tail, and a scraper chain. The head, feed bin, conveyor bin, discharge bin, and tail are connected sequentially. The scraper chain is a ring chain that rotates within the feed bin, conveyor bin, and discharge bin under the drive of the central sprockets at the head and tail. An arc-shaped baffle is provided at the tail, positioned outside the central sprocket. This submerged scraper conveyor, by incorporating the arc-shaped baffle, allows material to be smoothly carried out by the chain, effectively preventing material from remaining in the bin.

[0004] The buried scraper conveyor disclosed in the above-mentioned utility model patent has an anti-blocking door on the bottom plate of the head or tail of the machine. When a blockage occurs, the anti-blocking door is opened for cleaning. However, due to the limited space inside the conveyor, the efficiency of removing the accumulated material from the anti-blocking door is low, and it is more difficult to move the material when the volume of the stagnant material is large, which makes it inconvenient to clean the blocked material with the buried scraper conveyor. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-clogging device for a buried scraper conveyor and a buried scraper conveyor equipped with the anti-clogging device, which solves the problem of inconvenient operation in clearing blocked materials from buried scraper conveyors in existing technologies.

[0006] According to an embodiment of this utility model, an anti-clogging device for a buried scraper conveyor is installed on the head or tail of the buried scraper conveyor. It includes a housing communicating with the head or tail, with through slots on opposite sides of the housing. A movable frame that can be raised and lowered is provided on the housing, and two baffles are spaced apart on the movable frame, located on opposite sides of the housing. A rotatable connecting rod is also provided on the movable frame. A fixed frame and a handle rotatably connected to the fixed frame are also provided on the housing. One end of the fixed frame rotatably connected to the handle extends directly above the movable frame. A transition rod is provided on the handle, and the transition rod is rotatably connected to the end of the connecting rod away from the movable frame. When the handle is rotated, the connecting rod drives the movable frame to rise and fall on the housing, causing the baffles to move closer to or away from the opening of the slots. When the handle is rotated until the transition rod abuts against the side of the fixed frame away from the movable frame, the baffles are misaligned from the slots.

[0007] Furthermore, the housing is also provided with a sliding groove, the length direction of which is consistent with the vertical direction, and the baffle is movably disposed within the sliding groove.

[0008] Furthermore, the housing is also provided with a limiting plate, which covers the opening at one end of the slide groove, and the baffle covers the opening of the groove when it abuts against the limiting plate.

[0009] Furthermore, the fixing frame is provided with a clearance groove and the handle is rotatably disposed in the clearance groove, and the length of the adapter rod is greater than the width of the clearance groove.

[0010] Furthermore, the housing is also provided with a support frame, which is located near the slot. The support frame is provided with a guide cylinder and a movable rod is provided inside the guide cylinder. The movable rod has a tapered head at one end near the slot.

[0011] Furthermore, a spring is provided inside the guide cylinder, and the spring abuts against the movable rod and drives the movable rod to move away from the slot.

[0012] Furthermore, the movable rod is also provided with an operating rod, which is located at the end of the movable rod away from the slot.

[0013] Furthermore, the housing is also provided with an observation window, which is located on one side of the housing and communicates with the space enclosed by the housing.

[0014] On the other hand, according to an embodiment of the present invention, a buried scraper conveyor is also provided, including the above-mentioned buried scraper conveyor anti-blocking device.

[0015] Compared with existing technologies, this utility model has the following advantages: By using slots on both sides of the shell to clean up the material stuck inside, the material inside the shell can be pushed from one slot to the other, making it easier to remove the accumulated material. During the operation of the scraper conveyor, the slot opening is closed by a baffle covering it. When cleaning the inside of the shell is required, turning the handle causes the handle to move the connecting rod, and the movement of the connecting rod causes the movable frame to rise, moving the baffle to a position offset from the slot, so that the slot is fully opened. When the slot is open, the adapter rod on the handle abuts against the fixed frame, keeping the movable frame in the position where the baffle and the slot are offset. After the material accumulated inside the shell is cleaned, turning the handle in the opposite direction causes the movable frame to descend under the action of the connecting rod until the baffle covers the opening of the slot, thus closing the slot again. This solves the technical problem of inconvenient operation when cleaning blocked materials in existing scraper conveyors, resulting in the technical effect of easy removal of blocked materials and simple operation, which helps to keep the scraper conveyor unobstructed and ensures its stable operation.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes an anti-blocking device for a buried scraper conveyor, which is installed on the head or tail of the buried scraper conveyor and is used to clear the blockage of the buried scraper conveyor when material blockage occurs inside the buried scraper conveyor.

[0022] Please refer to Figure 1 and Figure 3The anti-clogging device for the buried scraper conveyor includes a housing 1 connected to the head or tail of the conveyor. The housing 1 has through slots 11 on opposite sides. A movable frame 2 is mounted on the housing 1, and two baffles 21 are spaced apart on the movable frame 2, located on opposite sides of the housing 1. The movable frame 2 also has a rotatable connecting rod 22. The housing 1 also has a fixed frame 3 and a handle 31 rotatably connected to the fixed frame 3. One end of the fixed frame 3 rotatably connected to the handle 31 extends directly above the movable frame 2. The handle 31 has a connecting rod 32. The adapter rod 32 is rotatably connected to the end of the connecting rod 22 away from the movable frame 2. When the handle 31 is rotated, the connecting rod 22 drives the movable frame 2 to rise and fall on the housing 1 and make the baffle 21 approach or move away from the opening of the slot 11. When the baffle 21 covers the opening of the slot 11, the slot 11 is closed. When the baffle 21 moves away from the opening of the slot 11, the slot 11 is open. When the handle 31 is rotated to the point where the adapter rod 32 abuts against the side of the fixed frame 3 away from the movable frame 2, the baffle 21 is offset from the slot 11 so that the slot 11 remains open.

[0023] Specifically, the operation steps for clearing the obstruction of the buried scraper conveyor using the anti-blocking device provided in this embodiment are as follows: When material blockage occurs in the buried scraper conveyor, rotate the handle 31 to move the connecting rod 22, and the movement of the connecting rod 22 will cause the movable frame 2 to rise, moving the baffle 21 to a position offset from the slot 11 so that the slot 11 is fully opened. When the slot 11 is open, the adapter rod 32 on the handle 31 abuts against the fixed frame 3 to make the movable frame 2 rise. The frame 2 is held in a position where the baffle 21 is misaligned with the slot 11. At this time, material inside the housing 1 can be pushed from one side of the slot 11 to the other side, facilitating the removal of accumulated material. After the material accumulated inside the housing 1 is cleared, the handle 31 is rotated in the opposite direction, causing the movable frame 2 to descend under the drive of the connecting rod 22 until the baffle 21 covers the opening of the slot 11, thus closing the slot 11 again. At this time, the scraper conveyor can continue to operate while keeping the housing 1 closed. The anti-blocking device for the scraper conveyor provided in this embodiment can easily remove material blocking the scraper conveyor, and the opening and closing operation of the slot 11 is simple, which helps to keep the scraper conveyor unobstructed and ensures stable operation.

[0024] like Figure 1As shown, the housing 1 is also provided with a sliding groove 12. The length direction of the sliding groove 12 is consistent with the vertical direction, and the baffle 21 is movably disposed within the sliding groove 12. The sliding groove 12 is provided on the housing 1 for the installation of the baffle 21 to limit the movement direction of the baffle 21 on the housing 1, prevent the baffle 21 from deviating unexpectedly and causing gaps between the baffle 21 and the housing 1, resulting in material leakage, and guide the movement of the baffle 21 through the sliding groove 12 to improve the stability of the movable frame 2 during movement.

[0025] In this embodiment, the housing 1 is further provided with a limiting plate 13. The limiting plate 13 covers the opening at one end of the slide groove 12, and when the baffle 21 abuts against the limiting plate 13, it covers the opening of the slot 11. The limiting plate 13 is disposed at the bottom of the slide groove 12. When the movable frame 2 falls to the position where the baffle 21 abuts against the limiting plate 13 under its own gravity, the baffle 21 closes the opening of the slot 11, and the limiting plate 13 supports the baffle 21, keeping the baffle 21 in the position of closing the slot 11.

[0026] like Figure 3 As shown, the fixing frame 3 is provided with a clearance groove 33, and the handle 31 is rotatably disposed in the clearance groove 33. The length of the adapter rod 32 is greater than the width of the clearance groove 33. When the handle 31 is rotated, the handle 31 moves within the clearance groove 33 to prevent the fixing frame 3 from obstructing the rotation of the handle 31. The width of the adapter rod 32 is set to be greater than the width of the clearance groove 33 so that when the handle 31 is rotated to the position where the adapter rod 32 abuts against the fixing clamp, the handle 31 can remain in that position. At this time, the baffle 21 is held in the position that opens the slot 11 to prevent the baffle 21 from accidentally falling when cleaning the material accumulated inside the housing 1.

[0027] Please combine Figure 2 and Figure 3 The housing 1 is also provided with a support frame 4, which is located near the slot 11. The support frame 4 is provided with a guide cylinder 41, and a movable rod 42 is provided inside the guide cylinder 41. The movable rod 42 has a conical head 43 at one end near the slot 11. The guide cylinder 41 on the support frame 4 is used to guide the movement of the movable rod 42. When the movable rod 42 moves along the axial direction of the guide cylinder 41, the conical head 43 passes through the slot 11 and inserts or exits into the housing 1. When the conical head 43 is inserted into the housing 1, it acts on the material accumulated in the housing 1 to agitate the material in the housing 1 and prevent the material from getting stuck in the housing 1 and being difficult to remove.

[0028] Please refer to Figure 2 The guide cylinder 41 is equipped with a spring 44, which abuts against the movable rod 42 and drives the movable rod 42 to move away from the slot 11. When the movable rod 42 is moved to insert the conical head 43 into the slot 11, the spring 44 is further compressed. After the movable rod 42 is released, the spring 44 returns to its original length and pushes the movable rod 42 away from the housing 1, so that the conical head 43 exits the housing 1. The elastic force provided by the spring 44 keeps the conical head 43 outside the housing 1, preventing the baffle 21 from colliding with the conical head 43 when it falls and closes the slot 11.

[0029] In detail, the movable rod 42 is also provided with an operating rod 45, which is located at the end of the movable rod 42 away from the slot 11. By operating the operating rod 45, the conical head 43 can be easily inserted into the housing 1, facilitating the control of the movement of the movable rod 42 within the guide cylinder 41.

[0030] like Figure 1 As shown, the housing 1 is also provided with an observation window 14, which is located on one side of the housing 1 and communicates with the space enclosed by the housing 1. The observation window 14 is used to observe the material accumulation inside the housing 1, so as to stop the operation of the scraper conveyor and clean the material inside the housing 1 according to the actual situation.

[0031] On the other hand, according to an embodiment of the present invention, a buried scraper conveyor is also provided, including the above-mentioned buried scraper conveyor anti-blocking device.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
