Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a curved belt conveyor. Background Art

[0002] Open-pit mining is a process of removing the covering on the ore body to obtain the desired minerals. According to the type of mining, it can generally be divided into open-pit metal ore mining, open-pit coal mining and open-pit iron ore mining. In open-pit mining, conveyors are generally used to replace manual transportation of minerals.

[0003] When the conveying distance is long, the conveying length of one conveyor is not enough, so two conveyors are often spliced ​​together for use. The more common way is to overlap the two conveyors, one high and one low, so that the minerals transported on the higher conveyor will automatically fall onto the lower conveyor.

[0004] However, this overlapping method has the following problems: the mineral conveying trajectory cannot be extended completely in a straight line, and the end position of the high conveyor and the end position of the low conveyor are not easy to overlap, which results in the minerals falling from the high conveyor cannot be effectively taken over by the low conveyor.

[0005] The patent application document with application number 202310574826.8 discloses a self-moving turning conveyor, in which the first frame and the second frame realize the turning function of the belt conveyor through the first material receiving drum and the second material receiving drum that can rotate relatively, thereby realizing the effective reception of fallen minerals.

[0006] However, the following situations are unavoidable: operator negligence, operating errors, or long-term operation of the second frame belt conveyor, mechanical fatigue, and slow speed make the belt transmission speed of the first frame and the belt transmission speed of the second frame unsynchronized, especially when the belt transmission speed of the first frame is greater than the belt transmission speed of the second frame, the ore at the starting end of the second frame belt is excessively accumulated, so that part of the ore at the starting end of the second frame belt is scattered to the ground, causing waste.

DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the specific implementation methods, structures, features and effects of the utility model application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] like Figures 1 to 4 As shown, an embodiment of the utility model provides a curved belt conveyor, which includes: a first belt conveyor 1, a second belt conveyor 2, a material guiding part and a swinging part;

[0032] The conveying surface of the second belt conveyor 2 is lower than the conveying surface of the first belt conveyor 1, and a bracket 3 is fixed above the starting end of the second belt conveyor 2;

[0033] The material guide portion includes a first material guide cylinder 4 and a second material guide cylinder 5, wherein the lower end of the first material guide cylinder 4 is fixedly connected to the bracket 3, the lower end of the second material guide cylinder 5 is rotatably connected to the upper inner side wall of the first material guide cylinder 4, and the upper end side of the second material guide cylinder 5 is connected to the first belt conveyor 1;

[0034] The swinging part includes a swinging plate 6 and a cam 7. The upper side of the swinging plate 6 is rotatably connected to the edge of the lower port of the first material guide cylinder 4. The wheel axle of the cam 7 is rotatably connected to the bracket 3. The edge of the hub of the cam 7 is connected to the swinging plate 6 to drive the swinging plate 6 to swing back and forth along the conveying direction of the second belt conveyor 2.

[0035] The working process of a curved belt conveyor is as follows:

[0036] After the relative angle between the first belt conveyor 1 and the second belt conveyor 2 is adjusted, the first belt conveyor 1 and the second belt conveyor 2 are started, and the material on the conveying surface of the first belt conveyor 1 enters the second material guide cylinder 5 and the first material guide cylinder 4 in sequence, and finally falls to the conveying surface of the second belt conveyor 2.

[0037] Even if the transmission speed of the first belt conveyor 1 is greater than the transmission speed of the second belt conveyor 2, the amount of ore received by the starting end of the second belt conveyor 2 per unit time is greater than the amount of ore output from the starting end of the second belt conveyor 2. However, due to the rotation of the cam 7, the elliptical major axis end of the cam 7 and the elliptical minor axis end of the cam 7 alternately contact the swing plate 6, so that the swing plate 6 swings back and forth with the upper side as the center, driving the falling ore to be periodically thrown to the conveying surface of the second belt conveyor 2 along the conveying direction of the second belt conveyor 2, thereby preventing the ore from gradually accumulating at the starting end of the second belt conveyor 2, thereby preventing the ore at the starting end of the second belt conveyor 2 from falling to the ground.

[0038] In the technical solution of the utility model, the device periodically swings the swing plate 6 to prevent the mineral materials output from the lower port of the first material guide cylinder 4 from falling to the starting end of the second belt conveyor 2, and the auxiliary mineral materials are spread evenly on the conveying surface of the second belt conveyor 2.

[0039] Specifically, the lower end of the second material guiding cylinder 5 is rotatably mounted on the inner side of the upper end of the first material guiding cylinder 4 through a bearing.

[0040] Specifically, the bracket 3 is fixedly connected to the frame of the second belt conveyor 2, and the cam 7 is an elliptical cam 7. The driving method of the cam 7 can be as follows:

[0041] A driving motor is fixedly mounted on the side of the bracket 3 , and an output shaft of the driving motor is coaxially connected to the axle of the cam 7 .

[0042] like Figure 1 As shown, in a specific embodiment, in the conveying direction of the second belt conveyor 2 , the cam 7 is located between the starting end of the second belt conveyor 2 and the first material guiding cylinder 4 .

[0043] In this embodiment, specifically, when the elliptical short axis end of the cam 7 is connected to the swing plate 6, the swing plate 6 naturally droops, and the mineral material naturally falls to the starting end of the second belt conveyor 2. When the elliptical long axis end of the cam 7 is connected to the swing plate 6, the swing plate 6 rotates forward by a certain angle, and the swing plate 6 forms an inclined surface with a certain angle, and the mineral material slides down along the inclined surface. The landing point of the mineral material on the conveying surface of the second belt conveyor 2 is located in front of the starting end, thereby preventing the mineral material from always falling to the starting end of the second belt conveyor 2.

[0044] like Figures 2 to 4 As shown, in a specific embodiment, the wheel shaft of the cam 7 is coaxially connected to the driven wheel 8, the starting end pulley of the second belt conveyor 2 is coaxially connected to the driving wheel 9, and the driving wheel 9 is connected to the driven wheel 8 through a belt drive.

[0045] In this embodiment, specifically, during the operation of the first belt conveyor 1 and the second belt conveyor 2, the pulley of the second belt conveyor 2 drives the driving wheel 9 to rotate, the driving wheel 9 drives the driven wheel 8 to rotate, the driven wheel 8 drives the cam 7 to rotate, and the elliptical major axis end and the elliptical minor axis end of the cam 7 alternately contact the swing plate 6, driving the swing plate 6 to swing.

[0046] Specifically, in this embodiment, the power of the second belt conveyor 2 is used to drive the cam 7 to rotate, and no additional power equipment is needed, thereby reducing capital investment.

[0047] like Figure 1 As shown, in a specific embodiment, it also includes a receiving tray 10, which is fixedly connected to the upper end of the second material guiding cylinder 5, and the side of the receiving tray 10 is connected to the frame of the first belt conveyor 1.

[0048] In this embodiment, specifically, a circular hole is provided in the center of the receiving tray 10, and the circular hole is seamlessly welded to the edge of the upper port of the second material guide barrel 5. The receiving tray 10 is concave downward from the edge to the center, thereby increasing the receiving area of ​​the mineral material and guiding all the mineral material into the second material guide barrel 5.

[0049] In a specific embodiment, the swing plate 6 is an arc-shaped surface, which is used to prevent the mineral materials from scattering along the two sides of the swing plate 6.

[0050] In the present embodiment, specifically, the center of curvature of the arc-shaped surface of the swing plate 6 is toward the central axis of the first material guide cylinder 4, and the mineral material slides down along the arc-shaped inner surface of the swing plate 6. The left and right sides of the swing plate 6 are relatively raised to prevent the mineral material from spreading to the left and right sides. In the process of the swing plate 6 swinging forward, the falling mineral material is thrown out in a straight line along the conveying direction of the second belt conveyor 2, which reduces the width of the thrown mineral material and reduces the probability of the mineral material scattering on the ground.

[0051] like Figure 1 As shown, in a specific embodiment, it also includes a lifting mechanism, which includes a screw rod 11 and a slider 12. The tail end of the frame of the first belt conveyor 1 is provided with a vertical slide rail, and the two ends of the screw rod 11 are respectively rotatably connected to the opposite ends of the slide rail. The slider 12 is threadedly connected to the screw rod 11, and the slider 12 is slidably connected to the slide rail. The slider 12 is provided with a slot, and the side of the receiving tray 10 is inserted into the slot, and the opposite side walls of the slot are respectively provided with first limiting holes, and the side of the receiving tray 10 is provided with a second limiting hole, and the first limiting hole corresponds to the second limiting hole, which is used to insert a limiting pin 13.

[0052] In this embodiment, specifically, the ground flatness of the mining site is not good. After the location of the device is changed, the relative heights of the conveying surfaces of the first belt conveyor 1 and the second belt conveyor 2 also change, the slot and the receiving tray 10 no longer correspond, and the side of the receiving tray 10 cannot be inserted into the slot accordingly.

[0053] At this time, the screw rod 11 can be rotated to drive the slider 12 to move up and down along the slide rail, so that the slot and the receiving tray 10 correspond to each other again, so that the side of the receiving tray 10 can be inserted into the slot.

[0054] Through this embodiment, the docking and assembly work of the first belt conveyor 1 and the second belt conveyor 2 can smoothly adapt to the mine ground with poor flatness, thereby improving the environmental adaptability of the equipment.

[0055] like Figure 1 As shown, in a specific embodiment, a crank 14 is also included, and the crank 14 is fixedly connected to the lower end of the screw rod 11.

[0056] In this embodiment, specifically, the operator can hold the crank handle 14 to drive the screw rod 11 to rotate, thereby driving the slider 12 to slide up and down along the slide rail.

[0057] like Figure 1 As shown, in a specific embodiment, universal wheels 15 are respectively installed at the lower end of the frame of the first belt conveyor 1 and the lower end of the frame of the second belt conveyor 2, and the universal wheels 15 are provided with brakes.

[0058] In this embodiment, specifically, the first belt conveyor 1 and the second belt conveyor 2 can be pushed to a desired position by rolling the universal wheel 15 , and at the same time, the relative angle between the frame of the first belt conveyor 1 and the frame of the second belt conveyor 2 can be easily changed.

[0059] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
