Description

Technical Field

[0001] The invention relates to the technical field of conveyor material guide structures, and in particular to an adjustable material guide trough of a belt transportation system, which is suitable for DT2 series belt conveyors and TM96 series belt conveyors. Background Art

[0002] The material guide chute is installed at the receiving end of the belt conveyor so that the material falling from the hopper is concentrated in the middle part of the conveyor belt before reaching the belt speed, thus preventing the material from spilling out.

[0003] The guide chute can be divided into the type with anti-overflow skirt and the fully enclosed type; if it is the fully enclosed type, it consists of three parts: upper, middle and lower. The middle side plate is connected to the conveyor frame and is the fixed part. The upper cover and the lower bottom plate are connected to the side plates by bolts. However, with the increase in feeding speed and the wide discharge port of the chute, the material is discharged unevenly, which causes the belt conveyor to deviate and cause material blockage. In severe cases, it will cause certain safety hazards to on-site operators.

[0004] Therefore, it is necessary to design and modify the belt conveyor material guide trough to effectively prevent the uneven discharge of the transported materials, thereby solving the problem of belt conveyor deviation caused by the above problems. Summary of the invention

[0005] In order to solve the above problems, the present invention provides an adjustable material guide trough, which can adjust the opening direction and size of the material guide trough by fixing a groove bracket on a fixed rod. Corresponding adjustments can be made according to different material receiving conditions, which can effectively solve the problem of material receiving being not centered, and manual operation is quick and labor-saving.

[0006] In order to achieve the above object, the specific technical solution adopted by the present invention is as follows:

[0007] An adjustable material guide chute, comprising:

[0008] Support frame;

[0009] A top plate, arranged horizontally and fixedly mounted on the supporting frame;

[0010] Movable side panels are vertically arranged on both sides of the top panel, and the top ends are movably connected to the top panel;

[0011] The groove bracket is transversely arranged on the outer side of the movable side plate, and a plurality of groove brackets (a plurality of groove brackets is at least two groove brackets) are arranged at intervals along the longitudinal direction of each movable side plate; the inner end of the groove bracket is movably connected to the movable side plate, and the bracket body is provided with a plurality of groove brackets with openings facing downwards in parallel;

[0012] A fixing rod is longitudinally arranged on the outer side of the movable side plate and fixedly mounted on the supporting frame so as to be fixed by the groove of the groove bracket.

[0013] The adjustable material guide trough of the present invention can adjust the opening size and direction of the material guide trough through the movable connection between the movable side plate and the groove bracket, and the movable side plate and the top plate, and can be fixed after adjustment through the snap fit between the groove bracket and the fixing rod, so that the material guide trough structure remains stable.

[0014] Preferably, the adjustable material guide chute further comprises a connecting rod connecting adjacent groove brackets, the connecting rod being longitudinally arranged outside the fixing rod and passing through the outer end of the groove bracket. The setting of the connecting rod ensures the consistency of the opening adjustment of the material guide chute, reduces local deviation, further improves the stability of the overall structure of the material guide chute, and facilitates on-site operation.

[0015] Preferably, the support frame includes at least two support units arranged at intervals along the longitudinal direction of the movable side panels, each support unit includes two top supports fixedly connected to both sides above the top panel and two vertically arranged side supports respectively connected to the outer ends of the two top supports, and the top of the side support is fixedly connected to the top support.

[0016] Furthermore, the bottom of the side bracket is welded and fixed to the belt conveyor channel steel, and the fixing rod is welded and fixed to the side bracket.

[0017] Preferably, the top end of the movable side panel is movably connected to the side end of the top panel via a first hinge. The top panel and the side panel are connected in a hinged manner, which facilitates the adjustment of the side panel in different directions.

[0018] Furthermore, the connection gap between the top end of the movable side plate and the side end of the top plate is wrapped with wear-resistant rubber and fixed with bolts to improve the airtightness of the material guide chute and reduce material loss and environmental pollution.

[0019] Preferably, the inner end of the groove bracket is movably connected to the outer surface of the movable side plate through a second hinge. The groove bracket and the movable side plate are connected in a hinged manner to flexibly adapt to the opening adjustment of the guide chute and reduce the difficulty of fixing the movable side plate.

[0020] Preferably, the inner surface of the movable side plate is detachably connected with a wear-resistant lining plate. The lining plate of the required material can be equipped or replaced according to the actual situation on site. The detachable connection includes but is not limited to threaded connection, mortise and tenon connection, plug-in connection and the like.

[0021] Preferably, the movable side plate is connected to the fixed side plate of the adjacent fixed material guide trough through wear-resistant rubber and fixed with bolts, so as to avoid the adjustment of the movable side plate affecting the connection of the adjacent fixed material guide trough and improve the airtightness.

[0022] The present invention has the following beneficial effects:

[0023] 1. The present invention designs the material guide trough into an adjustable form through the combined structural design of the material guide trough top plate, side plate and groove bracket, combined with the optimization of the connection and fixing methods, so that the material guide trough is no longer restricted to the original fixed form. When the material receiving deviation occurs, there is no need to modify the chute, which reduces manpower and material resources. The opening direction and size of the material guide trough can be adjusted according to different situations, which can effectively solve the problem of uneven material receiving and avoid the deviation of the belt conveyor and the blockage and safety hazards caused by it.

[0024] 2. The present invention has a simple structure and is easy to maintain. The guide trough can be adjusted and fixed by manually operating the groove bracket. The operation is simple and fast, saving time and effort.

[0025] 3. The present invention ensures the structural stability of the material guide chute after adjustment through the cooperation of the groove bracket, the fixing rod and the connecting rod.

[0026] 4. The present invention uses wear-resistant rubber and bolts to connect the movable side plate to the top plate, and the movable side plate to the fixed side plate, thereby providing airtightness of the material guide chute without affecting the adjustment flexibility of the movable side plate, thereby reducing material loss and environmental pollution.

[0027] 5. The inner wall of the movable side plate of the present invention can be bonded with different wear-resistant materials, and can be repaired more quickly when the wear-resistant lining plate is damaged, and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] An adjustable material guide trough 1, such as Figure 1 and 2 As shown, it includes a supporting frame, a top plate 1-3, a movable side plate 1-4, a first hinge 1-5, a second hinge 1-6, a groove bracket 1-7, a fixing rod 1-8, and a connecting rod 1-9.

[0038] The top plate 1-3 is arranged horizontally, and the movable side plates 1-4 are arranged vertically on both sides of the top plate 1-3. The top end of the movable side plates 1-4 is movably connected to the side ends of the top plate 1-3 through the first hinge 1-5, so that the movable side plates 1-4 can be adjusted in different directions, thereby adjusting the size and direction of the guide trough opening. The connection gap between the top end of the movable side plates 1-4 and the side ends of the top plate 1-3 is covered with wear-resistant rubber 1-10 and fixed with bolts 1-11 (such as Figure 3 The inner surface of the movable side plate 1-4 is detachably connected with a wear-resistant lining plate, so that different wear-resistant materials can be laminated on the inner wall of the movable side plate 1-4, thereby expanding the applicable scope of conveying materials and facilitating replacement.

[0039] The support frame includes two support units arranged at intervals along the longitudinal direction, and each support unit includes two top supports 1-1 fixedly connected to both sides above the top plate 1-3 and two vertically arranged side supports 1-2 respectively connected to the outer ends of the two top supports 1-1; the top of the side support 1-2 is fixedly connected to the top support 1-1, and the inner side of the bottom is welded and fixed to the belt conveyor channel steel 3.

[0040] The groove bracket 1-7 is transversely arranged on the outer side of the movable side panel 1-4, and two groove brackets are arranged along the longitudinal direction of each movable side panel 1-4; the inner end thereof is movably connected to the outer surface of the movable side panel 1-4 through the second hinge 1-6, and the frame body is provided with a plurality of grooves with openings facing downwards in parallel; the outer side of the movable side panel 1-4 is also longitudinally arranged with a fixing rod 1-8, and the fixing rod 1-8 is welded and fixed to the side bracket 1-2, so as to be fixed by the groove of the groove bracket 1-7. The arrangement of the second hinge 1-6 and the fixing rod 1-8 enables the groove bracket 1-7 to flexibly adapt to the opening adjustment of the guide trough and reduces the difficulty of fixing the movable side panel 1-4.

[0041] The groove brackets 1-7 on both sides of the movable side plate 1-4 are connected by a connecting rod 1-9 respectively. Figure 1 and 4 As shown, the connecting rod 1-9 is longitudinally arranged on the outside of the fixing rod 1-8, penetrates the outer end of the groove bracket 1-7, and is combined with the fixing rod 1-8 to ensure the stability of the material guide trough structure and improve the impact resistance level.
