Description

Technical Field

[0001] This utility model relates to the field of material conveying machinery technology, and in particular to a stirring device for a material conveying machine that prevents accumulation. Background Technology

[0002] Material conveyors, especially screw conveyors, are widely used material conveying equipment in industries such as chemical, building materials, and grain processing. They are mainly used to convey powdery, granular, or small lump materials.

[0003] However, in practical applications, many powdery or granular materials have poor flowability. This makes it very easy for materials to accumulate, bridge, or clump during the conveying process, especially at the inlet of the conveyor from the hopper and inside the conveyor housing.

[0004] This accumulation problem manifests itself in the following ways: materials form bridging at the discharge port of the hopper, preventing them from smoothly entering the conveyor below, causing a feeding interruption. Even if the materials enter the conveyor housing, they may agglomerate and clump together again during the process of being pushed by the conveying screw due to pressure or the characteristics of the materials themselves. These clumps, in turn, will hinder the rotation of the conveying screw, increase the motor load, and even cause the equipment to jam and stop.

[0005] While existing conveyors or hoppers may be equipped with a single agitation or vibration device, such as an agitator bar inside the hopper to prevent bridging, this design overlooks the problem of secondary agglomeration of materials inside the conveyor housing. Once agglomerates form inside the housing, the thrust of the conveying screw alone is insufficient to break them up, still leading to low conveying efficiency and blockages. Therefore, existing technologies cannot simultaneously solve the dual problems of preventing bridging at the discharge port and preventing agglomeration during conveying, thus failing to achieve smooth material transport throughout the entire process.

[0006] Therefore, this utility model proposes a material conveyor mixing device to prevent accumulation, thereby overcoming the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the prior art where materials in conveyors tend to accumulate and bridge at the hopper discharge port and easily agglomerate and cause blockages in the conveying bin, this utility model aims to provide a conveyor mixing device with an improved structure that can effectively solve the above problems and prevent accumulation.

[0008] This utility model provides a material conveyor mixing device for preventing accumulation, including: a trapezoidal bin with a discharge port, a loading bin fixedly connected to the upper part of the trapezoidal bin, and a conveying screw rotatably disposed inside the trapezoidal bin.

[0009] The device also includes a first motor, a first gear, a second gear, a connecting rod, a connecting bar, a second motor, a rotating rod, a first pulley, a second pulley, and a synchronous belt.

[0010] The first gear is fixedly connected to the output end of the first motor; the second gear is rotatably disposed between the material hopper and the trapezoidal hopper and meshes with the first gear for transmission; the lower end of the connecting rod is fixedly connected to the second gear through a connecting strip and extends upward into the material hopper.

[0011] Furthermore, the first pulley is fixedly connected to the output end of the second motor, the rotating rod is rotatably set inside the trapezoidal bin and located above the conveying screw, the second pulley is fixedly connected to one end of the rotating rod, and the synchronous belt is wound around the first pulley and the second pulley.

[0012] Preferably, a fixing plate is horizontally fixedly connected to the connecting rod.

[0013] Preferably, a connecting block is fixedly connected to the rotating rod.

[0014] Preferably, a slice is fixedly connected to the connecting block.

[0015] Preferably, the second gear has a hollow structure, with annular grooves on both its upper and lower surfaces. The device also includes an upper interface and a lower interface. The upper interface is fixedly connected to the lower opening of the material hopper and accommodated in the groove on the upper surface of the second gear. The lower interface is fixedly connected to the upper opening of the trapezoidal hopper and accommodated in the groove on the lower surface of the second gear.

[0016] Preferably, the device further includes a fixing block on which the first motor is mounted.

[0017] Preferably, the device further includes a fixing cover, which is fixedly connected to the upper part of the trapezoidal compartment, and a fixing block is fixedly connected to the fixing cover. The fixing cover covers the outside of the first gear and the second gear.

[0018] Preferably, the axis of the rotating rod is parallel to the axis of the conveying screw.

[0019] This utility model has the following beneficial effects: 1. In this utility model, by setting a first-stage stirring mechanism inside the material hopper, which is driven by a first motor and gear transmission, thereby driving the connecting rod and the fixed plate to rotate, the problem of material accumulation or bridging at the discharge port of the hopper in the prior art is solved, thus achieving the technical effect of actively and continuously disturbing the material, preventing the discharge port from being blocked, and ensuring a stable supply of material.

[0020] 2. In this utility model, by setting a rotating rod crushing mechanism with slicing and connecting blocks, which is independently driven by a second motor inside the trapezoidal bin and above the conveying screw, the problem that materials may still agglomerate and clump after falling into the conveying bin, which may easily lead to excessive load or jamming of the conveying screw is solved. This achieves the technical effect of pre-crushing and mixing the materials to ensure continuous and stable subsequent screw conveying. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example 1

[0023] Please refer to Figures 1 to 5 This utility model provides a material conveyor mixing device to prevent accumulation, which aims to solve the problems in the prior art where materials are prone to accumulating and bridging at the discharge port of the loading hopper and easily agglomerate and clump in the conveying hopper, causing conveying blockage.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the anti-accumulation conveyor mixing device includes a trapezoidal bin 1, a discharge port 8 on the trapezoidal bin 1, a material loading bin 10 fixedly connected to the upper part of the trapezoidal bin 1, and a conveying screw 7 rotatably disposed inside the trapezoidal bin 1. The conveying screw 7 is used to push the material to the discharge port 8 for discharge.

[0025] To achieve dual anti-accumulation mixing, the device also includes a first motor 2, a first gear 13, a second gear 15, a connecting rod 19, a connecting strip 18, a fixing plate 20, a second motor 3, a rotating rod 9, a first pulley 4, a second pulley 6, a synchronous belt 5, a connecting block 21, and a slice 22.

[0026] Specifically, the first-stage mixing mechanism is set inside the material hopper 10. The first motor 2 is used to provide power. The first gear 13 is fixedly connected to the output end of the first motor 2. The second gear 15 is rotatably set between the material hopper 10 and the trapezoidal hopper 1. The second gear 15 meshes with the first gear 13 for transmission. The connecting rod 19 extends upward into the material hopper 10. The lower end of the connecting rod 19 is fixedly connected to the second gear 15 through the connecting strip 18. Thus, when the first motor 2 drives the second gear 15 to rotate, the connecting rod 19 will stir in the material hopper 10. To increase the stirring range, a fixing plate 20 is horizontally fixedly connected to the connecting rod 19.

[0027] The second-stage mixing and crushing mechanism is set inside the trapezoidal bin 1. The second motor 3 is used to provide power. The first pulley 4 is fixedly connected to the output end of the second motor 3. The rotating rod 9 is rotatably set inside the trapezoidal bin 1 and is located above the conveying screw 7. One end of the rotating rod 9 is fixedly connected to the second pulley 6. The synchronous belt 5 is wound around the first pulley 4 and the second pulley 6. The second motor 3 drives the rotating rod 9 to rotate through the transmission mechanism. In order to crush the material, a connecting block 21 is fixedly connected to the rotating rod 9, and a slice 22 is fixedly connected to the connecting block 21.

[0028] To achieve power transmission and material passage between the loading bin 10 and the trapezoidal bin 1, please refer to the following: Figure 2 and Figure 4The second gear 15 has a hollow structure, and annular grooves 16 are provided on both its upper and lower ends. The device also includes an upper interface 17 and a lower interface 14. The upper interface 17 is fixedly connected to the lower opening of the material hopper 10, and the lower interface 14 is fixedly connected to the upper opening of the trapezoidal hopper 1. In the assembled state, the upper interface 17 is housed in the groove 16 on the upper end of the second gear 15, and the lower interface 14 is housed in the groove 16 on the lower end of the second gear 15. This fixed interface and rotating groove cooperation structure ensures that when the first motor 2 drives the second gear 15 to rotate, the connecting rod 19 rotates accordingly, and the material can fall through the fixed upper interface 17, the hollow channel of the second gear 15, and the fixed lower interface 14 in sequence.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, in order to enhance the efficiency and contact range of the first-stage mixing, a fixing plate 20 is horizontally fixedly connected to the connecting rod 19. The fixing plate 20 rotates synchronously with the connecting rod 19, which can expand the disturbance range of the material in the loading bin 10 and effectively break up large-area lumps.

[0030] In another preferred embodiment, in order to provide structural support and protection for the second-stage mixing system, the device further includes a fixing block 12, on which the first motor 2 is mounted. The device also includes a fixing cover 11, which is fixedly connected to the upper part of the trapezoidal chamber 1. The fixing block 12 is fixedly connected to the fixing cover 11. The fixing cover 11 covers the outside of the first gear 13 and the second gear 15, providing stable support and protection for the first motor 2 and the internal transmission components.

[0031] As another preferred embodiment, in order to enhance the strength of the second-stage mixing and crushing, a connecting block 21 is fixedly connected to the rotating rod 9. The connecting block 21 is used to assist in the turning and dispersing of materials, and a slice 22 is fixedly connected to the connecting block 21. The slice 22 can shear and crush large particles in the material to form a multi-layer mixing and crushing structure, making it difficult for materials to agglomerate.

[0032] As another preferred embodiment, in order to make the material conveying and stirring directions consistent, the axis of the rotating rod 9 is parallel to the axis of the conveying screw 7.

[0033] In another preferred embodiment, to clarify the driving structure of the connecting rod 19, the lower end of the connecting rod 19 is fixedly connected to the inner wall of the second gear 15 by a connecting strip 18. The connecting strip 18 rotates synchronously with the second gear 15, thereby driving the connecting rod 19.

[0034] Working principle: When the equipment is working, the first motor 2 installed on the fixed block 12 outputs power, driving the first gear 13 at the output end of the first motor 2 to rotate. The first gear 13 meshes with the second gear 15, thereby driving the second gear 15 to rotate around its own axis. At this time, the connecting strip 18 on the inner wall of the second gear 15 moves synchronously with the gear, driving the connecting rod 19 to perform a circular stirring motion in the material bin 10. The fixed plate 20 on the connecting rod 19 expands the contact range of the material stirring. By using the continuous disturbance of the material by the connecting rod 19, the material is prevented from accumulating and blocking in the material bin 10, ensuring that the material can flow smoothly. The material passes through the upper interface 17, through the inner wall of the second gear 15, and then through the lower interface 14 into the trapezoidal bin 1. The fixed cover 11 and fixed block 12 at the top of the trapezoidal bin 1 provide stable support for the transmission components inside the first motor 2 and the fixed cover 11. The second gear 15 has sliding grooves 16 on both the upper and lower sides. The upper interface 17 and the lower interface 14 are located in the sliding grooves 16 on the second gear 15. When the second gear 15 rotates, since the upper interface 17 and the lower interface 14 are fixedly connected to the material bin 10 and the trapezoidal bin 1 respectively, the second gear 15 rotates between the upper interface 17 and the lower interface 14 through the sliding grooves 16.

[0035] After the material falls into the trapezoidal bin 1, the second motor 3 at one end of the conveying screw 7 starts. The first pulley 4 at the output end of the second motor 3 drives the synchronous belt 5, causing the second pulley 6 at one end of the rotating rod 9 to drive the rotating rod 9 to rotate inside the trapezoidal bin 1. The connecting block 21 and the slice 22 on the rotating rod 9 form a multi-layer mixing and crushing structure. The slice 22 shears and crushes large particles of material, while the connecting block 21 assists in turning and dispersing the material. Under the synergistic effect of the two, the material in the trapezoidal bin 1 is fully mixed and crushed, eliminating material agglomeration. The processed material can be smoothly discharged from the discharge port 8 under the push of the conveying screw 7.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
