Description
Technical Field
[0001] This utility model relates to the field of scraper conveyor technology, specifically to a scraper conveyor transition trough. Background Technology
[0002] Scraper conveyors are a type of conveying equipment widely used in industries such as coal and mining. They convey materials by the movement of scraper chains within the trough. Transition troughs, as an important component of scraper conveyors, are used to connect standard troughs of different heights or angles, serving as a transitional connection.
[0003] However, in actual use, due to the complex working conditions of coal mining faces, it is difficult to adjust the height between the transition trough and the machine head to an aligned state before placing the transition trough on the ground for connection. This results in an unstable connection between the transition trough and the machine head, which is prone to loosening during long-term operation, leading to material leakage and affecting conveying efficiency.
[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content
[0005] The purpose of this utility model is to provide a transition trough for scraper conveyors, in order to solve the problem mentioned in the background art that when connecting the transition troughs of the scraper conveyor head, it is difficult to adjust the height between the transition trough and the head to an aligned state, which easily leads to an unstable connection between the transition trough and the head, affecting the conveying efficiency of the scraper conveyor.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] The scraper conveyor transition trough includes the transition trough components and also includes:
[0008] The head unit includes a head body located at the output end of the transition trough for transferring the material output from the transition trough;
[0009] The connecting unit includes an end connecting component disposed between the head body and the transition groove for calibrating the vertical direction of the head body, and side connecting components disposed on both sides of the connection between the head body and the transition groove for calibrating the horizontal direction of the head body.
[0010] Furthermore, the end connection component includes:
[0011] A limiting block is fixedly connected to one end of the transition groove located on the head body, and is used to calibrate the vertical direction of the head body;

[0013] The first screw is inserted into the first fastening hole, and the upper part of the first screw extends into the machine head body for connecting the machine head body and the transition groove.
[0014] Furthermore, the machine head body has a threaded hole inside and outside the first thread that is threaded to the first screw, for use in conjunction with the first screw to fasten the limiting block.
[0015] Furthermore, the head body is provided with a retraction groove at one end of the transition groove for accommodating the limiting block.
[0016] Furthermore, the height of the retraction groove is greater than the height of the limiting block, which is used to fit the machine head body into the limiting block and move it downward for calibration.
[0017] Furthermore, the distance from the plane where the upper end of the retraction groove is located to the plane where the lower end of the machine head body is located is equal to the distance from the plane where the upper end of the limiting block is located to the plane where the lower end of the transition groove is located, which is used to keep the lower end of the machine head body and the transition groove aligned after the machine head is installed.
[0018] Furthermore, the distance from the lower end of the retraction groove to the lower end of the limiting block is greater than the length of the first screw.
[0019] Furthermore, the side connection component includes:

Detailed Implementation
[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Example 1
[0037] Please see Figure 1-5 This utility model provides a technical solution:
[0038] The scraper conveyor transition trough includes transition trough component 100, and also includes:
[0039] The head unit 2 includes a head body 21 disposed at the output end of the transition trough 100 for transferring the material output from the transition trough 100;
[0040] The connecting unit 1 includes an end connecting component 11 disposed between the head body 21 and the transition groove 100 for calibrating the vertical direction of the head body 21, and side connecting components 12 disposed on both sides of the connection between the head body 21 and the transition groove 100 for calibrating the horizontal direction of the head body 21.
[0041] It should be noted that when connecting the machine head body 21 to the transition groove 100, the machine head body 21 is fitted onto the outside of the end connecting component 11 and moved downwards along the transition groove 100 until the machine head body 21 reaches the upper end of the end connecting component 11, thus completing the vertical calibration of the machine head body 21. In addition, during the process of the machine head body 21 moving downwards along the transition groove 100, the machine head body 21 drives the side connecting components 12 to fit onto both sides of the transition groove 100, thus completing the horizontal calibration of the machine head body 21. This calibration and installation method, which adopts a top-down approach, can avoid misalignment between the machine head body 21 and the transition groove 100 due to uneven ground, thereby improving the stability of the installation.
[0042] Example 2
[0043] like Figure 1-3 , Figure 5 As shown, components that are the same as or corresponding to those in the above embodiments are represented by the same reference numerals as those in the above embodiments. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:
[0044] The end connection component 11 includes:
[0045] The limiting block 111 is fixedly connected to one end of the transition groove 100 located on the head body 21, and is used to calibrate the vertical direction of the head body 21.
[0046] The first fastening hole 112 has two sets at the upper end of the limiting block 111;
[0047] The first screw 113 is inserted into the first fastening hole 112, and the upper part of the first screw 113 extends into the head body 21 for connecting the head body 21 and the transition groove 100.
[0048] Furthermore, the machine head body 21 has a threaded hole inside and outside the first thread that is threaded to the first screw 113, for use in conjunction with the first screw 113 to fasten the limiting block 111.
[0049] Furthermore, the head body 21 is provided with a retraction groove 22 at one end of the transition groove 100 for accommodating the limiting block 111.
[0050] The height of the retraction groove 22 is greater than the height of the limiting block 111, and it is used to fit the machine head body 21 into the limiting block 111 and move it downward for calibration.
[0051] Furthermore, the distance from the plane where the upper end of the retraction groove 22 is located to the plane where the lower end of the machine head body 21 is located is equal to the distance from the plane where the upper end of the limiting block 111 is located to the plane where the lower end of the transition groove 100 is located, which is used to keep the lower end of the machine head body 21 aligned with the lower end of the transition groove 100 after the machine head is installed.
[0052] It should be noted that during the process of connecting the machine head body 21 to one side of the transition groove 100, the machine head body 21 is first fitted onto the outside of the limiting block 111 through the retraction groove 22, and at this time the limiting block 111 is located at the lower position of the retraction groove 22. Then, the machine head body 21 is pushed downward along one side of the transition groove 100, so that the machine head body 21 moves downward and abuts against the upper end of the limiting block 111. At this time, the lower end of the machine head body 21 and the lower end of the transition groove 100 are on the same horizontal plane, thus completing the vertical installation and calibration of the machine head body 21.
[0053] Example 3
[0054] like Figure 4-5 As shown, components that are the same as or corresponding to those in the above embodiments are represented by the same reference numerals as those in the above embodiments. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:
[0055] The distance from the lower end of the retraction groove 22 to the lower end of the limiting block 111 is greater than the length of the first screw 113.
[0056] This design ensures that when the first screw 113 is inserted into the first fastening hole 112 after passing through the retraction groove 22, the retraction groove 22 will not obstruct the first screw 113.
[0057] Example 4
[0058] like Figure 2-4 As shown, components that are the same as or corresponding to those in the above embodiments are represented by the same reference numerals as those in the above embodiments. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:
[0059] The side connection component 12 includes:
[0060] The side extension block 121 is provided in two sets, which are respectively fixedly connected to the two sides of the head body 21 near the transition groove 100;
[0061] The hook plate 122 is fixedly connected to the side of the side extension block 121 near the transition groove 100. The lower end of the hook plate 122 cooperates with the side extension plate to form a groove, which is used to calibrate the horizontal position of the transition groove 100.
[0062] Furthermore, fixing blocks 1001 are fixedly connected to both sides of the transition groove 100 and near the connection with the machine head body 21. The fixing blocks 1001 are inserted into the groove formed by the lower end of the hook plate 122 and the side extension plate.
[0063] The fixing block 1001 has a first threaded hole 1002 inside.
[0064] Furthermore, a second fastening hole 1221 is provided on one side of the hook plate 122; a second threaded hole 23 coaxial with the second fastening hole 1221 is provided inside the fixing block 1001.
[0065] A second screw 123 is inserted into the second fastening hole 1221;
[0066] One end of the second screw 123 is threadedly connected to the second threaded hole 23, which is used to connect the transition groove 100 and the head body 21 with the mating end connection assembly 11.
[0067] It should be noted that when the machine head body 21 is fitted onto the outside of the limiting block 111 through the retraction groove 22, and the limiting block 111 is located at the lower position of the retraction groove 22, and then the machine head body 21 is pushed down along one side of the transition groove 100, the machine head body 21 drives the hook plate 122 to move down through the side extension block 121, so that the hook plate 122 moves from the original position above the fixed block 1001 to the outside of the fixed block 1001. At this time, the second fastening hole 1221 and the first threaded hole 1002 are in a coaxial state, completing the horizontal calibration of the machine head body 21. Thus, by calibrating the horizontal and vertical directions of the machine head body 21, the machine head body 21 can be aligned with the vertical height and the height of both sides of the transition groove 100, making the connection tighter and avoiding subsequent material leakage, which would affect the conveying efficiency.
[0068] After the calibration is completed, the first screw 113 is passed through the first fastening hole 112 and tightened into the second threaded hole 23, so that the transition groove 100 is initially connected to the machine head body 21 through the limiting block 111. Then, the second screw 123 is passed through the second fastening hole 1221 and tightened into the first threaded hole 1002, so that the transition groove 100 is further connected to the machine head body 21 through the fixing block 1001, ensuring a more stable connection between the transition groove and the machine head.
