Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of coal mine production conveyors, and in particular relates to an automatic lifting guide trough for belt conveyors. Background Technology
[0002] The feed chute is a key component of a belt conveyor. To ensure that the material falling from the discharge pipe is centered on the belt and to prevent overflow, a feed chute is typically installed at the tail section of the belt conveyor. Its purpose is to suppress dust and ensure that the material is loaded to the center of the conveyor. In existing technology, the feed chute is designed in three sections: a rear baffle, the chute body, and a front curtain. The steel plates on both sides of the chute body are connected to anti-overflow skirts, which serve to center the material and prevent overflow.
[0003] Conventional material guide chutes are fixedly connected to belt conveyors. The anti-overflow skirts of the material guide chutes are always in contact with the conveyor belt to shield both sides of the conveyor belt. During the operation of the conveyor belt, the top of the conveyor belt rubs against the bottom of the anti-overflow skirt. After a period of use, the bottom of the anti-overflow skirt will wear down, which will increase the gap between the conveyor belt and the anti-overflow skirt. This will affect the overall sealing and dust suppression effect of the equipment. At the same time, when material accumulates on one side of the side plate, as the conveyor belt is conveyed, the accumulated material will also squeeze the anti-overflow skirt, which will cause misalignment between the anti-overflow skirt and the conveyor belt. This will affect the sealing effect between the conveyor belt and the anti-overflow skirt, and may also cause the material guide chutes to lose their ability to control material alignment, resulting in the conveyor belt running off-center.
[0004] Moreover, the fixed connection between the feed chute and the belt conveyor can easily cause material blockage at the unloading point, which may even lead to equipment damage and unusability. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic lifting guide trough for belt conveyors.
[0006] To achieve the above objectives, the solution adopted by this utility model is as follows:

[0013] Preferably, the drive motor is fixed on the belt conveyor, and the angle between the push rod and the horizontal direction is 0-45°; when the drive motor drives the push rod to push out, the swing arm generates an upward thrust on the connecting rod, causing the connecting rod to slide upward on the support column; when the drive motor drives the push rod to pull in, the swing arm generates a downward pull on the connecting rod, causing the connecting rod to slide downward on the support column.
[0014] Preferably, the feed trough includes two symmetrical and inclined side plates, which form a funnel-shaped feed opening that is wider at the top and narrower at the bottom. An adjusting baffle is provided on the inner side of each side plate. The upper end of the adjusting baffle is fixed to the inner side of the side plate. A screw is provided in the middle of the adjusting baffle. One end of the screw is screwed to the side plate and the other end abuts against the adjusting baffle.

[0015] Preferably, anti-overflow rubber skirts are connected to the lower ends of the two side plates by clamping members.
[0016] Beneficial effects
[0017] This utility model provides an automatic lifting guide chute for belt conveyors. When material is detected passing by, the chute body and anti-overflow skirt are lowered to ensure material centering and suppress dust. When no material is passing by, the chute body and anti-overflow skirt are raised, separating the anti-overflow skirt from the conveyor belt, reducing wear on the anti-overflow skirt and frictional resistance of the conveyor belt. Adjustable baffles are also provided on the inner side of the two side plates. The angle of the baffles is controlled by screws to ensure material centering, prevent conveyor belt deviation, and ensure safe production. Attached Figure Description

[0026] Therefore, the following solutions are proposed:
[0027] See Figure 1-2 This utility model provides an automatic lifting guide trough 10 for belt conveyors, including a guide trough body 11, a trough support 12, and an automatic lifting assembly 13.
[0028] Specifically, in the automatic lifting guide trough 10 for a belt conveyor of this utility model, the guide trough body 11 is located above the belt conveyor 20 of the belt conveyor and extends along the length direction of the belt 30 of the belt conveyor 20. In some embodiments, the guide trough body 11 includes two symmetrical and inclined side plates 111, which form a funnel-shaped guide opening that is wider at the top and narrower at the bottom.
[0029] Furthermore, in the automatic lifting guide trough 10 for belt conveyors of this utility model, the trough support 12 includes support columns 121 and 122 located at the front end and rear end of the belt 30 of the belt conveyor 20, and each end includes two support columns 121a and 121b (or 122a and 122b) arranged on the left and right sides of the guide trough body 11.
[0030] Furthermore, in the automatic lifting guide trough 10 for belt conveyors of this utility model, the automatic lifting assembly 13 of the trough includes two automatic lifting assembly units 131 located at the front end and rear end of the belt 30 of the belt conveyor 20. Each automatic lifting assembly unit 131 includes a connecting rod 131a connecting two support columns 121a, 121b (or 122a, 122b) at one end, a swing rod 131b hinged to one end of the connecting rod 131a, a push rod 131c hinged to the end of the swing rod 131b, and a drive motor 132 connected to the push rod 131c. The connecting rod 131a can slide up and down to connect the two support columns 121a, 121b.
[0031] In some embodiments, each automatic lifting assembly unit 131 of the trough also includes a slide rail 131d located on two support columns 121a and 121b, and a sliding sleeve 131e is provided on the slide rail 131d. The sliding sleeve 131e can slide up and down on the slide rail 131d, and the connecting rod 131a is fixed on the sliding sleeve 131e. In this way, the connecting rod 131a can slide up and down on the two support columns 121a and 121b in a horizontal manner.
[0032] Furthermore, in each automatic lifting assembly unit 131 of the trough, the drive motor 132 driving the push rod 131c is fixed to the belt conveyor 20. The angle between the push rod 131c and the horizontal direction is 0-45°. The end of the push rod 131c and the end of the connecting rod 131a are respectively hinged to the two ends of the swing rod 131b. In this way, when the drive motor 132 drives the push rod 131c to push out or pull in, it can transmit an upward or downward force to the connecting rod 131a through the swing rod 131b. When the drive motor 132 drives the push rod 131c to push out, it generates an upward thrust on the connecting rod 131a through the swing rod 131b. In this way, the connecting rod 131a slides horizontally on the two support columns 121a and 121b. When the drive motor 132 drives the push rod 131c to pull forward, it generates a downward pulling force on the connecting rod 131a through the swing arm 131b. In this way, the connecting rod 131a slides horizontally on the two support columns 121a and 121b.
[0033] In the automatic lifting guide trough 10 for belt conveyors of this utility model, the tops of the two side plates 111 of the guide trough body 11 are suspended from the connecting rod 131a by the connecting member 14. When the drive motor 132 drives the push rod 131c to push out or pull in, the swing arm 131b generates an upward pushing force or a downward pulling force on the connecting rod 131a. The connecting rod 131a slides up or down horizontally on the two support columns 121a and 121b, and drives the guide trough body 11 to rise or fall through the connecting member 14.
[0034] In some embodiments, the automatic lifting guide trough 10 for belt conveyors of this utility model may also be equipped with an electrical control box, which is electrically connected to the drive motor 132. When a signal is received indicating that material is about to pass through, the switch of the electrical control box is activated, and the height of the guide trough 11 is automatically raised or lowered through the drive motor 132 and the automatic lifting assembly 13.
[0035] Furthermore, in the automatic lifting guide trough 10 for belt conveyors of this utility model, an adjusting baffle 112 is provided on the inner side of each of the two side plates 111 of the guide trough body 11. In some embodiments, the upper end of the adjusting baffle 112 is fixed on the inner side of the side plate 111, and a screw 113 is provided in the middle of the adjusting baffle 112. One end of the screw 113 is screwed to the side plate 111, and the other end abuts against the adjusting baffle 112. The tilt angle of the adjusting baffle 112 is adjusted by screwing the screw 113 in and out, thereby ensuring the centering of the material and preventing the conveyor belt from running off-center.
[0036] Furthermore, in the automatic lifting guide trough 10 for belt conveyors of this utility model, anti-overflow rubber skirts 114 are connected to the lower ends of the two side plates 111 of the guide trough body 11. In this utility model, a pressing member 115 is provided between each side plate 111 and the anti-overflow rubber skirt 114 to press the anti-overflow rubber skirt 114 onto the surface of the belt 30, thereby sealing the guide trough and preventing material from overflowing.
[0037] In the operation of the automatic lifting guide chute 10 for belt conveyors of this utility model, when the conveyed material arrives at the automatic lifting guide chute 10 via the upstream belt conveyor, the matching electrical control box receives a signal and starts the drive motor 132. Through the connecting rod 131a, swing rod 131b, and push rod 131c structure of the automatic lifting assembly 13, the height of the guide chute 11 is raised or lowered until the anti-overflow rubber skirt 114 is close to the belt 30. When material passes by, the clamping member 115 on the anti-overflow rubber skirt 114 is pressed to ensure that the anti-overflow rubber skirt 114 of the automatic lifting guide chute 10 contacts the belt 30, thereby preventing material from passing through. The material is positioned in the middle of the belt conveyor 20 to prevent overflow. If misalignment is detected as the material passes through the guide trough 11, the screws 113 on the two side plates 111 of the guide trough 11 can be rotated to adjust the tilt angle of the inner adjusting baffle 112, ensuring the alignment of the material and preventing the conveyor belt from running off-center. When no material is passing through, the drive motor 132 is started, and the guide trough 11 is lifted through the connecting rod 131a, swing rod 131b, and push rod 131c structure of the automatic lifting assembly 13, ensuring that the anti-overflow rubber skirt 114 is separated from the belt 30, reducing the wear and resistance of the belt 30.
[0038] This utility model provides an automatic lifting guide chute for belt conveyors. When material is detected passing by, the guide chute body and anti-overflow skirt are lowered to ensure material centering and suppress dust. When no material is passing by, the guide chute body and anti-overflow skirt are raised to separate the anti-overflow skirt from the conveyor belt, reducing wear on the anti-overflow skirt and frictional resistance of the conveyor belt.
[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
