DETAILED DESCRIPTION

[0038] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0039] Embodiment 1:

The feeding belt conveyor 1 can feed materials from one end, and the other end can transport the materials into the head funnel 2, thereby realizing the feeding function of the feeding belt conveyor 1.

[0041] Reference Figure 1 and Figure 2The feeding belt conveyor 1 includes a driving roller 14, a driven roller 15, a plurality of upper feeding rollers 12, a plurality of lower feeding rollers 13 and a frame 4. The conveyor belt in the feeding belt conveyor 1 is a feeding belt 11. Both ends of the driving roller 14, the driven roller 15, the upper feeding roller 12 and the lower feeding roller 13 are rotatably connected to the frame 4, and the feeding belt 11 passes through the driving roller 14, the driven roller 15, all the upper feeding rollers 12 and all the lower feeding rollers 13 in sequence. One end of the driving roller 14 is coaxially connected to a first driving motor 16. Driven by the first driving motor 16, the driving roller 14 can drive the feeding belt 11 to rotate to realize the material conveying function of the feeding belt conveyor 1. The upper feeding roller 12 adopts a grooved roller, which can reduce the situation where materials fall from the feeding belt conveyor 1.

[0042] Reference Figure 1 A return belt conveyor 3 is arranged at an interval on the vertical lower side of the feeding belt conveyor 1. The conveying direction of the feeding belt conveyor 1 is the same as the conveying direction of the return belt conveyor 3. Therefore, when the feeding belt 11 rotates to face the return belt conveyor 3, the return belt conveyor 3 can collect the materials dropped from the feeding belt 11.

[0043] Reference Figure 1 and Figure 2 The return material conveyor 3 includes an active roller 34, a plurality of return material upper rollers 32 and a plurality of return material lower rollers 33. The conveyor belt in the return material conveyor 3 is a return material conveyor belt 31. Both ends of the active roller 34, the return material upper rollers 32 and the return material lower rollers 33 are rotatably connected to the frame 4. The return material conveyor belt 31 passes through the active roller 34, all the return material upper rollers 32 and all the return material lower rollers 33 in sequence. One end of the active roller 34 is coaxially connected to a second drive motor 35. Driven by the second drive motor 35, the active roller 34 can drive the return material conveyor belt 31 to rotate to realize the material conveying function of the return material conveyor 3, so that the material dropped from the feeding belt conveyor 1 to the return material conveyor 3 can be conveyed. The active roller 34, the return material upper roller 32 and the return material lower roller 33 are arranged at the lower side of the feeding lower roller 13 and spaced from the feeding lower roller 13. Therefore, the feeding belt conveyor 1 and the returning belt conveyor 3 can share a frame 4, which is convenient for installation and positioning between the feeding belt conveyor 1 and the returning belt conveyor 3 and reduces the cost of the frame 4 at the same time.

[0044] Reference Figure 1 and Figure 2 One end of the feeding belt conveyor 1 is inserted into the feeding port 21 of the head funnel 2, and the rotation directions of the first drive motor 16 and the second drive motor 35 are the same, that is, the material conveying direction of the feeding belt conveyor 1 and the return belt conveyor 3 is the same, so that the material falling from the feeding belt conveyor 1 onto the return belt conveyor 3 can be re-conveyed to the head funnel 2 by the return belt conveyor 3.

[0045] Reference Figure 1 and Figure 2The upper return roller 32 and the lower return roller 33 are arranged in a one-to-one correspondence, and the upper return roller 32 and the corresponding lower return roller 33 are arranged at intervals in the vertical direction. A plurality of observation holes 41 are opened on both sides of the axial direction of the upper return roller 32 on the frame 4, and the plurality of observation holes 41 are arranged at intervals on the frame 4 along the length direction of the frame 4. Each observation hole 41 corresponds to an upper return roller 32 and a lower return roller 33. The corresponding upper return roller 32 and the lower return roller 33 can be observed through one observation hole 41, so that the opening of the observation hole 41 facilitates the observation and maintenance of the return belt conveyor 3 in the later stage.

[0046] Reference Figure 1 and Figure 3 A tensioning mechanism 5 is provided at one end of the return material belt conveyor 3. The tensioning mechanism 5 includes a tensioning roller 51. The tensioning roller 51 is arranged parallel to the axial direction of the active roller 34. Both ends of the tensioning roller 51 are rotatably connected to the frame 4. The tensioning roller 51 is arranged at the end of the frame 4 away from the head funnel 2. The active roller 34 is arranged at the end of the return material belt conveyor 3 close to the head funnel 2. The return material upper roller 32 and the return material lower roller 33 are arranged between the active roller 34 and the tensioning roller 51, and the return material belt 31 passes through the tensioning roller 51. The tensioning roller 51 can support the return material belt 31 without affecting the normal operation of the return material belt conveyor 3.

[0047] Reference Figure 1 and Figure 3 , tensioning frames 53 are provided at both ends of the tensioning roller 51 in the axial direction, the tensioning frames 53 are connected to the frame 4 by bolts, and the length direction of the tensioning frames 53 is arranged along the length direction of the frame 4, tensioning movable seats 54 are installed at both ends of the tensioning roller 51 in the axial direction, and the tensioning movable seats 54 are rotationally connected to the tensioning roller 51 by bearings, the tensioning movable seats 54 are slidably inserted in the corresponding tensioning frames 53, and the tensioning movable seats 54 are slidably connected to the corresponding tensioning frames 53 along the length direction of the frame 4. The tensioning movable seats 54 slide in the corresponding tensioning frames 53, and can drive the tensioning roller 51 to move, so that when the tensioning roller 51 becomes loose due to long-term friction and the return belt 31 becomes loose, the position of the tensioning roller 51 is adjusted by adjusting the position of the corresponding tensioning movable seats 54, so that the return belt 31 can be re-tensioned.

[0048] Reference Figure 1 and Figure 3A tensioning driving member 52 is arranged between the tensioning movable seat 54 and the corresponding tensioning frame 53. The tensioning driving member 52 adopts a lead screw. The tensioning driving member 52 is axially arranged along the length direction of the frame 4. One end of the tensioning driving member 52 is rotatably connected with the corresponding tensioning movable seat 54 and the tensioning driving member 52 axially contacts the tensioning movable seat 54. The other end is connected with the corresponding tensioning frame 53 by a thread. The tensioning driving member 52 rotates, and the tensioning driving member 52 can move along the length direction of the tensioning frame 53 through the setting of the thread, thereby driving the tensioning movable seat 54 to slide in the corresponding tensioning frame 53, so as to realize the adjustment of the tensioning roller 51.

[0049] Reference Figure 1 and Figure 3 In the tensioning mechanism 5, the position of the tensioning roller 51 is adjusted by the tensioning driving member 52, and the loss caused by the friction of the tensioning roller 51 is compensated by adjusting the position of the tensioning roller 51. The use of a lead screw as the tensioning driving member 52 makes the adjustment distance of the tensioning roller 51 long and the adjustment fine. In addition, since the tensioning roller 51 is independently provided with a tensioning frame 53, a tensioning driving member 52 and a tensioning movable seat 54 at both ends, when the wear on one side of the tensioning roller 51 is large, it is convenient to adjust the tensioning roller 51 on one side, and the operation is simple, which is convenient for later maintenance. At the same time, the installation method is simple, and it only needs to fix the tensioning frame 53 to the frame 4 on site.

[0050] Reference Figure 1 and Figure 4 A cleaning mechanism 6 is arranged on the vertical lower side of the return belt conveyor 3, and the cleaning mechanism 6 includes a cleaning roller brush 61. The cleaning roller brush 61 is rotatably connected to the frame 4 at both ends along the axial direction. A brush is arranged on the outer peripheral side of the cleaning roller brush 61. The brush is made of wear-resistant nylon. The side surface of the cleaning roller brush 61 is in contact with the return belt 31. A cleaning drive member 62 is coaxially arranged at one end of the cleaning roller brush 61. The cleaning drive member 62 adopts a variable frequency motor. When driven by the cleaning drive member 62, the cleaning roller brush 61 can clean the materials sticking on the return belt 31.

[0051] Reference Figure 1 and Figure 4 The cleaning mechanism 6 is arranged at one end of the return belt conveyor 3 close to the head funnel 2, and the cleaning drive member 62 drives the cleaning roller brush 61 to rotate in the same direction as the movement direction of the return belt 31 driven by the second drive motor 35, so that the cleaning roller brush 61 can directly sweep the material sticking on the return belt 31 into the head funnel 2, reducing material loss.

[0052] The implementation principle of the embodiment of the present application is as follows: materials are loaded at one end of the feeding belt conveyor 1, and then under the action of the feeding belt conveyor 1, the materials can be automatically fed into the head funnel 2 to realize the transportation of materials; when the materials sticking to the feeding belt 11 return vertically downward with the feeding belt 11, the vibration of the feeding belt conveyor 1 causes part of the materials to fall off the feeding belt conveyor 1 and fall onto the return belt conveyor 3. Under the conveyance of the return belt conveyor 3, the fallen materials are re-fed into the head funnel 2; and the materials sticking to the return belt 31 will be brushed into the head funnel 2 by the cleaning roller.

[0053] Embodiment 2:

The length direction of the scraper plate 7 is provided along the width direction of the frame 4 and the scraper plate 7 is detachably connected to the frame 4 at both ends along the length direction. The length direction of the scraper plate 7 is inclined along the vertical direction. The scraper plate 7 extends upwardly from bottom to top along the transport direction of the return belt conveyor 3. The vertical upper end of the scraper plate 7 is in contact with the feeding belt 11. The setting of the scraper plate 7 allows the compacted and sticky materials on the feeding belt 11 to be scraped off by the scraper plate 7 and fall onto the return belt 31, thereby reducing the residual materials on the feeding belt 11.

[0056] Reference Figure 5 and Figure 6 The scraper plate 7 includes a connecting component 71, a first scraper component 72 and a second scraper component 76.
