[0002] The automatic feeding chute (also known as the automatic centering feeding chute or self-correcting feeding chute) on a belt conveyor is a key device for optimizing the material conveying process. Its core function is to ensure that the material is centered on the conveyor belt, prevent deviation, spillage and wear, thereby improving the conveying efficiency and reducing equipment loss.

[0003] The traditional automatic feeding chute consists of two end frames, two integral feeding plates installed between them, and an integral connecting piece. The traditional automatic feeding chute has the following defects: 1. The length is fixed and it is only applicable to conveyors of specific lengths, with low flexibility in use; 2. When wear occurs, it needs to be disassembled and replaced as a whole, and it also needs to be customized according to the length of the conveyor belt, increasing the maintenance cost; 3. The long-term stability is not good. The installation of the feeding plate in the feeding chute and the connection between the feeding plate and the connecting piece are both realized by bolts. After the conveyor runs for a long time, the bolts are prone to loosen and fail under the action of the vibration force of the conveyor. Summary of the Invention

The L-shaped bracket corresponds to the connecting seam. Rectangular holes are provided on both the material guide plate and the end frame, and the rectangular holes are located on both sides of the connecting seam. The rectangular holes on both sides of the connecting seam extend through the horizontal section of the L-shaped bracket. Locking holes are provided after the two vertical sections of the buckling member are inserted into the rectangular holes on both sides of the connecting seam and the L-shaped bracket.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Refer to Figure 1, An automatic material guiding chute applicable to a belt conveyor, comprising a frame 1, several material guiding plates 5, several connecting pieces 6, several connecting crossbars 7 and several L-shaped brackets 8. Two end covers 3 are installed on the top of the frame 1, and the belt conveyor 2 is installed between the two end covers 3. End frames 4 are installed on the opposite surfaces of the two end covers 3.

[0038] Refer to Figure 1 , The end frame 4 is composed of a frame body, inclined plates fixedly installed at the lower ends of two opposite surfaces of the frame body, and flexible plates installed at the lower ends of the inclined plates. Several L-shaped brackets 8 are fixedly installed on the top of the frame 1 and are symmetrically arranged along the width direction of the frame 1.

[0039] Refer to Figure 1 、 Figure 4 And Figure 5 , Several material guiding plates 5 are arranged between the two end frames 4 and are symmetrically arranged along the width direction of the end frames 4, and the material guiding plates 5 on both sides are evenly arranged along the length direction of the frame 1. Adjacent two material guiding plates 5, and between the end frame 4 and the adjacent material guiding plate 5 of the end frame 4 are all connected by a plug-in component 50. The connecting pieces 6 correspond to the material guiding plates 5 one by one. When adjacent two material guiding plates 5 or the material guiding plate 5 and the end frame 4 are plugged in, the connecting piece 6 is locked on the material guiding plate 5 through a socket component 60. Multiple connecting seams are formed between adjacent material guiding plates 5 and between the material guiding plate 5 and the end frame 4.

[0040] During assembly, the number of material guiding plates 5 and connecting pieces 6 can be determined according to the length of the conveyor belt on the belt conveyor 2. Several material guiding plates 5, several connecting pieces 6 and two end frames 4 are spliced to form a material guiding chute, which is applicable to the conveyor belts on belt conveyors 2 of different lengths, expanding the applicable range of the material guiding chute and eliminating the problem that the traditional integrally fixed material guiding chute is difficult to lengthen or shorten according to the length of the belt conveyor 2 when the length of the belt conveyor 2 is adjusted and needs to replace the material guiding chute.

[0041] Both the connecting piece 6 and the flexible plate are made of rubber material with a certain flexibility. The lower ends of the connecting piece 6 and the flexible plate are both placed on the conveyor belt of the belt conveyor 2, so that there is a good connection between the material guiding plate 5 and the surface of the conveyor belt, preventing material offloading.

[0042] Refer to Figure 1 、 Figure 4 And Figure 6, a plurality of connecting crossbars 7 correspond to the connecting seams on the same side one by one, and plug connectors 70 are installed at both ends of the connecting crossbar 7. The connecting crossbar 7 is connected between two opposite connecting seams through the plug connectors 70. The two plug connectors 70 on the connecting crossbar 7 are respectively inserted into the material guide plate 5 or the corresponding end frame 4. When two adjacent material guide plates 5 or the material guide plate 5 and the end frame 4 are inserted through the insertion assembly 50, the plug connectors 70 are limited and locked, so as to lock the connecting crossbar 7 between the two connecting seams, reinforce both sides in the width direction of the material guide groove, and further improve the stability of the splicing and installation of the material guide groove.

[0043] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 , the L-shaped brackets 8 correspond to the connecting seams one by one, and the L-shaped brackets 8 and the material guide plates 5 on both sides of the connecting seams or the L-shaped brackets 8 and the end frames 4 are all tightly connected through the plug locking assemblies 80, so as to obtain a firm locking effect for the spliced material guide groove. A pull-down locking assembly 81 for locking the two plug locking assemblies 80 again is installed between two opposite L-shaped brackets 8. The plurality of L-shaped brackets 8 are integrally locked and limited through the locking assembly 82 and the plurality of pull-down locking assemblies 81.

[0044] After the L-shaped brackets 8 and the material guide plates 5 on both sides of the connecting seams, and the L-shaped brackets 8 and the end frames 4 are all tightly connected through the plug locking assemblies 80, when connecting the plurality of L-shaped brackets 8 through the locking assembly 82, the plug locking assemblies 80 are secondarily locked through the pull-down locking assembly 81, so that a plurality of material guide plates 5, a plurality of connecting pieces 6, two end frames 4, a plurality of connecting crossbars 7 and a plurality of L-shaped brackets 8 are all connected by insertion. It avoids the problem that when using the traditional bolt connection method, the screws on the material guide groove fall off due to the vibration force generated during the operation of the belt conveyor 2, affecting the stability of the material guide groove.

[0045] Refer to Figure 1 , Figure 4 and Figure 6 , the insertion assembly 50 includes plug-in parts 501 installed at both ends of one of the end frames 4 and one side of the material guide plate 5. The cross-section of the plug-in part 501 is L-shaped. Slots 502 matching the plug-in parts 501 are opened at both ends of the other end frame 4 and the other side of the material guide plate 5. The cross-section of the slot 502 is L-shaped matching the plug-in part 501; the plug connector 70 is T-shaped, a T-shaped groove 71 communicating with it is opened on the slot 502, and a clamping groove for clamping the plug connector 70 is opened on the plug-in part 501.

[0046] During assembly, align the plug connector 70 at one end of the connecting cross bar 7 with the corresponding T-slot 71 and insert it into the corresponding T-slot 71, and then connect the two adjacent guide plates 5 or the guide plate 5 and the end frame 4 through the corresponding plug-in 501 and the slot 502. When the plug-in 501 is inserted into the slot 502, the card slot on the plug-in 501 is also stuck in the connecting section between the plug connector 70 and the connecting cross bar 7, so that the connecting cross bar 7 is clamped and fixed between the two opposite connecting seams, and the two sides of the guide groove in the width direction are reinforced, thereby improving the stability of the splicing installation of the guide groove. At the same time, after the plug-in 501 is inserted into the slot 502, it can also limit the horizontal movement of the two adjacent guide plates 5 or the guide plate 5 and the end frame 4.

[0047] See also Figure 1 and Figure 5 The plug-in assembly 60 includes a fixing piece 601 installed on one side of the connecting piece 6 arranged along the thickness direction thereof, a mounting groove is provided on the guide plate 5, and a plurality of fixing columns 602 evenly arranged along the length direction thereof are installed in the mounting groove, the fixing piece 601 is sleeved on the fixing columns 602 through mounting holes provided thereon corresponding to the fixing columns 602 one by one, and a locking member for locking the fixing piece 601 is installed on the plug-in 501 and the guide plate 5 together.

[0048] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The locking member includes an insertion rod 610 installed at the lower end of the plug-in 501 and a blocking piece 611 installed on one side of the guide plate 5 and the end frame 4 where a slot 502 is provided. The fixing plate 601 is provided with a plugging hole 613 for plugging with the insertion rod 610. The slot 502 is provided with a through hole (not shown in the figure) for facilitating the insertion rod 610 to penetrate the slot 502 and be plugged with the plugging hole 613. The blocking piece 611 is provided with a U-shaped groove 612.

[0049] The fixing plate 601 with the connecting plate 6 is sleeved on the multiple fixing columns 602 through the mounting holes. When the plug-in 501 is inserted into the slot 502, the insertion rod 610 passes through the slot 502 and is plugged into one end of the fixing plate 601. At the same time, the blocking plate 611 on the corresponding material guide plate 5 or the end frame 4 is also sleeved on the corresponding fixing column 602 on the side away from the slot 502 through the U-shaped groove 612, so as to realize the integrated fixation of the fixing plate 601 and the connecting plate 6 when the material guide trough is spliced and installed, eliminating the installation inconvenience existing in the traditional method of directly fixing the connecting plate 6 on the material guide plate 5 by multiple screws.

[0050] See also Figure 4 and Figure 5, one end of the connecting piece 6 arranged along its length direction is provided with a plurality of overlapping grooves 620, and the other end of the connecting piece 6 is provided with a plurality of overlapping strips 621 arranged along its width direction. The overlapping strips 621 are made of the same material as the connecting piece 6. The overlapping grooves 620 and the overlapping strips 621 correspond one by one. The adjacent two connecting pieces 6 are matched by the plurality of overlapping grooves 620 and the plurality of overlapping strips 621, avoiding the problem that when the adjacent two connecting pieces 6 guide the material, misalignment occurs, resulting in the material entering between the connecting piece 6 and the conveyor belt and affecting the material guiding effect.

[0051] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 , the plug - lock assembly 80 includes a buckling member 801 composed of a horizontal section and two vertical sections. The L - shaped bracket 8 corresponds to the connection seam. Rectangular holes 802 are provided on both the material guiding plate 5 and the end frame 4. The rectangular holes 802 are both located on both sides of the connection seam. The rectangular holes 802 on both sides of the connection seam extend through the horizontal section of the L - shaped bracket 8. After the two vertical sections of the buckling member 801 are inserted into the rectangular holes 802 on both sides of the connection seam and the L - shaped bracket 8, locking holes are provided. The buckling member 801 plugs and connects the adjacent two material guiding plates 5 or the end frame 4 and the adjacent material guiding plate 5 on the L - shaped bracket 8.

[0052] Refer to Figure 8 and Figure 9 , a receiving seat 803 is installed on the L - shaped bracket 8. A pair of symmetrically arranged locking members 804 that are slidably connected to the receiving seat 803 and are inserted and locked with the two locking holes on the buckling member 801 are provided. The locking members 804 are inserted into the locking holes to fix the buckling member 801 and the material guiding plate 5 or the end frame 4. A bidirectional screw 805 is also rotatably connected to the receiving seat 803. The bidirectional screw 805 is connected to the two locking members 804 in a threaded - fit manner.

[0053] Specifically, the locking member 804 is composed of an ear plate 830 and a plug post 831 installed on the side wall of the ear plate 830. A sliding groove for slidably connecting with the ear plate 830 is provided on the receiving seat 803. The bidirectional screw 805 is connected to the ear plate 830 in a threaded - fit manner.

[0054] After the buckling member 801 is inserted into the adjacent two material guiding plates 5 or the end frame 4 and the adjacent material guiding plate 5 and plugged on the L - shaped bracket 8, rotate the bidirectional screw 805. The bidirectional screw 805 drives the ear plate 830 and the plug post 831 to move towards the vertical section of the corresponding buckling member 801 through threaded - fit until the ear plate 830 abuts against the vertical section of the buckling member 801, and the plug post 831 is inserted into the locking hole. Then, the plug post 831 is further inserted and locked by pulling down the locking assembly 81, thereby preventing the bidirectional screw 805 from driving the ear plate 830 and the plug post 831 to move under the action of vibration force.

[0055] Refer to Figure 8 、 Figure 9 and Figure 10 , the drop-down locking assembly 81 includes a lifting bar 810 that is vertically slidably connected to the vertical section of the L-shaped bracket 8. A lower insertion frame 811 is installed at the top of the lifting bar 810. The lower insertion frame 811 is in an inverted U shape. Two locking members 804 are provided with limiting grooves after passing through the corresponding locking holes. The limiting grooves are opened on the insertion post 831. Two vertical sections of the lower insertion frame 811 are inserted into the corresponding limiting grooves to further limit the locking members 804. A connecting bar 812 is installed between the two opposite lifting bars 810.

[0056] Before the insertion post 831 is inserted into the locking hole, manually push the connecting bar 812 upward first to facilitate the insertion of the insertion post 831 into the locking hole. After the two opposite locking assemblies 80 both fix the guide plate 5 or the end frame 4 to the corresponding L-shaped bracket 8, then release the connecting bar 812. The connecting bar 812 drives the two vertical sections of the lower insertion frame 811 to be inserted into the corresponding limiting grooves, thereby limiting the axial movement of the insertion post 831 and preventing the insertion post 831 from detaching from the vertical section of the fastening member 801, further improving the firmness of the installation of the guide chute.

[0057] Refer to Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 and Figure 10 , the locking assembly 82 includes a connecting plate 820 installed between two opposite L-shaped brackets 8. A connecting hole is opened in the middle of the connecting plate 820. Multiple connecting holes are connected by connecting columns 821. The connecting hole is in an inverted U shape, improving the convenience of placing and installing the connecting column 821. One end and the side wall of the connecting column 821 are fixedly sleeved with limiting members 822 inserted into the corresponding connecting plate 820. The other end of the connecting column 821 is connected to a pressing ring 823 that abuts against the corresponding connecting plate 820 by means of threaded cooperation. A limiting socket 824 corresponding to the connecting bar 812 is also installed on the connecting column 821. Specifically, the limiting socket 824 is composed of a fixing ring fixedly sleeved on the connecting column 821 and an inverted L-shaped insertion plate installed on the fixing ring. A limiting insertion hole inserted into the limiting socket 824 is opened on the connecting bar 812.

[0058] After the pull-down locking component 81 plugs and limits the plug lock component 80, the connecting column 821 is placed into the connecting hole from the lower opening of the connecting hole. At this time, the inverted L-shaped plug board is aligned with the limiting jack, and then the connecting column 821 is moved so that the limiting member 822 is plugged into and abutted against the corresponding connecting plate 820. At the same time, the horizontal section of the inverted L-shaped plug board is inserted into the limiting jack, and then the pressing ring 823 is threadedly connected to the connecting column 821 until the pressing ring 823 abuts against the corresponding connecting plate 820. The pressing ring 823 and the limiting member 822 cooperate to limit the axial movement of the connecting column 821, and the inverted L-shaped plug board is plugged into the limiting jack to limit the up and down movement of the connecting column 821, thereby integrally locking and limiting multiple L-shaped brackets 8 and multiple pull-down locking components 81, further improving the installation firmness of the material guiding groove.

[0059] Refer to Figures 1 - 10 , during assembly: First step, align the plug joints 70 at both ends of the connecting cross bar 7 with the corresponding T-shaped grooves 71 and insert them into the corresponding T-shaped grooves 71. Then, plug the adjacent two material guiding plates 5 or the material guiding plate 5 and the end frame 4 through the corresponding plug-in parts 501 and slots 502. When the plug-in part 501 is inserted into the slot 502, the card slot on the plug-in part 501 is stuck on the section where the plug joint 70 is connected to the connecting cross bar 7, thereby clamping and fixing the connecting cross bar 7 between the opposite two connecting seams, strengthening both sides in the width direction of the material guiding groove. Repeat the above steps to connect the two end frames 4, several material guiding plates 5, and several connecting pieces 6 in sequence to form a material guiding groove.

[0060] Second step, lock and connect several L-shaped brackets 8 with the corresponding material guiding plates 5 and the L-shaped brackets 8 with the corresponding end frames 4 through the plug lock component 80, and then, through the pull-down locking component 81 provided between the opposite two L-shaped brackets 8, lock the opposite two plug lock components 80 again.

[0061] Third step, place the connecting column 821 into the connecting hole from the lower opening of the connecting hole.
