Description

Technical Field

[0001] This utility model relates to the field of tubular chain conveyors, and in particular to an anti-blocking device for tubular chain conveyors used in feed production. Background Technology

[0002] In the feed production and processing process, tubular chain conveyors are the core equipment for the continuous transport of powdery and granular feed raw materials and finished products. With their advantages of being closed and environmentally friendly and having flexible layout, they are widely used in the feed production and transportation process.

[0003] However, the materials involved in feed production generally have high oil content and fluctuating moisture content, which leads to two major problems at the feed inlet of the tubular chain conveyor: First, the material clumps due to the viscosity of oil and the action of moisture, or forms a bridging structure on the inner wall of the feed hopper, hindering the material from falling; Second, fine powder in the feed accumulates in the feed channel, gradually reducing the effective feed cross-section, eventually causing the feed channel to become blocked, preventing the material from smoothly entering the tubular chain conveyor and causing the conveying to be interrupted. Utility Model Content

[0004] The main purpose of this utility model is to provide a tube chain conveyor anti-blocking device for feed production, which can effectively solve the problem of easy blockage at the feed inlet of traditional tube chain conveyors.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tubular chain conveyor anti-clogging device for feed production includes a tubular chain conveyor body. A feed transition frame is fixedly connected to the feed inlet of the tubular chain conveyor body. An indexing disc type feeding mechanism is fixedly connected above the feed transition frame and connected to the discharge port of the indexing disc type feeding mechanism. A feed hopper assembly is fixedly connected above the feed inlet of the indexing disc type feeding mechanism. A power transmission system is fixedly connected below the feed transition frame of the tubular chain conveyor body, and drives the feed hopper assembly and the indexing disc type feeding mechanism through the power transmission system.

[0006] Preferably, the indexing disc type feeding mechanism includes a feeding cavity, an indexing disc rotating shaft is rotatably connected above the feeding cavity, a fixed disc is fixedly connected above the indexing disc rotating shaft, a movable partition and a fixed partition are provided between the indexing disc rotating shaft and the fixed disc, and a partition positioning pin is engaged above the fixed disc.

[0007] Preferably, the inner side of the movable partition is fixedly connected to a partition sliding guide rail, the inner side of the fixed partition is provided with a sliding groove and is slidably connected to the partition sliding guide rail, the upper part of the partition sliding guide rail is fixedly connected to a partition adjusting block, the outer side of the partition positioning pin is provided with a slot and is engaged with the partition adjusting block, and the fixed partition is fixedly connected to the indexing plate shaft.

[0008] Preferably, a feeding chamber cover is fixedly connected to the outside of the fixed plate, and a maintenance cover is rotatably connected to the feeding chamber cover above the fixed plate.

[0009] Preferably, the feeding hopper assembly includes a feeding hopper body, a stirring shaft is rotatably connected to the inner side of the feeding hopper body, a feeding port is provided above the top cover of the feeding chamber and is fixedly connected to the discharge port at the bottom of the feeding hopper body, and the feeding chamber has a discharge port on the side of the fixed plate away from the feeding hopper body and is fixedly connected to the feeding transition frame.

[0010] Preferably, the power transmission system includes a transmission main shaft, a fixed seat is fixedly connected above the feeding chamber, the fixed seat is rotatably connected to the transmission main shaft, the main body of the tubular chain conveyor is fixedly connected below the transmission main shaft to a drive motor that is its power source, pulleys are provided on the outer sides of the indexing disc shaft and the transmission main shaft and are driven by belts, and pulleys are also provided on the top of the transmission main shaft and the stirring shaft and are driven by belts.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a tube chain conveyor anti-clogging device for feed production. By setting a stirring shaft in the body of the feed hopper and using a power transmission system to drive the stirring shaft to continuously stir the material, it can directly break up the material agglomeration and bridging structure, and avoid the material from clogging at the feed hopper outlet. At the same time, in conjunction with the fixed and movable partitions of the indexing plate type feeding mechanism, the material is divided into quantitative material grids and pushed in batches, preventing the material from being blocked by a large amount of material rushing into the tube chain conveyor body at any time. This forms a dual anti-clogging mechanism of dispersion and batching, reducing the probability of blockage at the feed inlet of the traditional tube chain conveyor.

[0012] 2. This utility model provides a pipe chain conveyor anti-clogging device for feed production. Through the sliding cooperation design of movable and fixed partitions, when it is necessary to adjust the feeding mode according to the characteristics of feed materials or the production line capacity, the operator only needs to open the maintenance cover, remove the partition positioning pin, and move the partition adjustment block to drive the movable partition to move along the partition sliding guide rail. When the movable partition moves away from the fixed partition, the number of material compartments increases and the volume of each compartment decreases, forming a feeding mode suitable for fine powder materials and low capacity, avoiding the accumulation and blockage of fine powder. When the movable partition and the fixed partition are combined, the number of material compartments decreases and the volume of each compartment increases, forming a feeding mode suitable for granular materials and high capacity, improving conveying efficiency and enhancing the adaptability of the device to different feed materials and different production conditions.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1 As shown, this utility model provides an anti-clogging device for a tubular chain conveyor in feed production, including a tubular chain conveyor body 1. A feeding transition frame 2 is fixedly connected to the feed inlet of the tubular chain conveyor body 1. A dividing plate type feeding mechanism 3 is fixedly connected above the feeding transition frame 2 and connected to the discharge port of the dividing plate type feeding mechanism 3. A feeding hopper assembly 4 is fixedly connected above the feed inlet of the dividing plate type feeding mechanism 3. A power transmission system 5 is fixedly connected below the feeding transition frame 2 of the tubular chain conveyor body 1, and drives the feeding hopper assembly through the power transmission system 5. The main body 1 of the tubular chain conveyor serves as the conveying carrier, with its inlet fixedly connected to the feeding transition frame 2. The feeding transition frame 2 receives the material discharged from the indexing disc feeding mechanism 3, and the feeding hopper assembly 4 is connected above the indexing disc feeding mechanism 3, forming a pre-processing link for temporary storage and decentralized feeding. The power transmission system 5 is fixed to the position of the main body 1 of the tubular chain conveyor below the feeding transition frame 2, and is connected to the indexing disc feeding mechanism 3 and the feeding hopper assembly 4 respectively through pulleys and belts, thus constructing a transmission system with a single power source driving two mechanisms.

[0017] like Figure 2-4As shown, this utility model provides a pipe chain conveyor anti-blocking device for feed production. The indexing disc type feeding mechanism 3 includes a feeding cavity 31, an indexing disc shaft 38 rotatably connected above the feeding cavity 31, a fixed disc 35 fixedly connected above the indexing disc shaft 38, a movable partition 36 and a fixed partition 37 provided between the indexing disc shaft 38 and the fixed disc 35, a partition positioning pin 34 snapped onto the top of the fixed disc 35, a partition sliding guide rail 310 fixedly connected to the inner side of the movable partition 36, and an opening on the inner side of the fixed partition 37. The slide is slidably connected to the partition sliding guide rail 310. A partition adjusting block 39 is fixedly connected above the partition sliding guide rail 310. The outer side of the partition positioning pin 34 is provided with a slot and engages with the partition adjusting block 39. The fixed partition 37 is fixedly connected to the indexing plate rotating shaft 38. The feeding cavity 31 is fixedly connected to the outer side of the fixed plate 35 with a feeding cavity cover 311. The feeding cavity cover 311 is rotatably connected to the upper part of the fixed plate 35 with a maintenance cover 33. The feeding cavity 31 serves as a feeding space carrier. When the fixed partition 37 and the indexing plate... The rotating shaft 38 is rigidly connected. When it rotates synchronously with the indexing plate shaft 38, it can divide the material in the feeding chamber 31 into independent compartments, realizing the basic function of rotational pushing. The movable partition 36 is slidably connected to the fixed partition 37 through the partition sliding guide rail 310. The number and volume of compartments can be changed by adjusting the position. The outer groove of the partition positioning pin 34 is adapted to the partition adjustment lever 39 of the movable partition 36. When the movable partition 36 is adjusted to the target position, the partition positioning pin 34 can lock its position to prevent the movable partition from being damaged by vibration during the feeding process. The offset of plate 36 ensures the stability of the material compartment volume. The partition adjustment block 39 fixed above the partition sliding guide rail 310 provides the operator with an adjustment force point. By moving the partition adjustment block 39, the movable partition 36 can be moved synchronously without the need for additional tools, simplifying the adjustment process. At the same time, the upper cover 311 of the feeding cavity fixed on the outside of the feeding cavity 31 not only seals the feeding space, but also rotates and connects to the maintenance cover 33 above the fixed plate 35. Opening the maintenance cover 33 allows operation of components such as the fixed plate 35 and the partition positioning pin 34.

[0018] like Figure 4-5As shown, this utility model provides a tubular chain conveyor anti-blocking device for feed production. The feeding hopper assembly 4 includes a feeding hopper body 41, with a stirring shaft 42 rotatably connected to the inner side of the feeding hopper body 41. A feeding port is provided above the upper cover 311 of the feeding chamber and is fixedly connected to the discharge port at the bottom of the feeding hopper body 41. The feeding chamber 31 has a discharge port on the side of the fixed plate 35 away from the feeding hopper body 41 and is fixedly connected to the feeding transition frame 2. The power transmission system 5 includes a transmission main shaft 51, with a fixed seat 32 fixedly connected above the feeding chamber 31 and rotatably connected to the transmission main shaft 51. The tubular chain conveyor body 1 has a drive motor 52, the power source of the conveyor, fixedly connected below the transmission main shaft 51. The indexing plate rotating shaft 38 and the outer side of the transmission main shaft 51 are both provided with pulleys and connected to the outside of the conveyor. The feed is driven by a belt. The top of the main drive shaft 51 and the stirring shaft 42 are also equipped with pulleys and driven by belts. When the feed is put into the feed hopper body 41, the blades of the stirring shaft 42 continuously stir the feed, breaking up the clumps and bridging structures formed by the oil and moisture, ensuring that the feed falls in a loose state. At the same time, the feed inlet above the feed chamber cover 311 is connected to the discharge outlet at the bottom of the feed hopper body 41 to prevent the feed from spilling during the fall. The drive motor 52 is connected to the main drive shaft 51 by its output end, providing power to the main drive shaft 51. The main drive shaft 51 is connected to the indexing disc rotating shaft 38 of the indexing disc type feeding mechanism 3 by pulleys and belts, driving the indexing disc rotating shaft 38 to rotate above the feed chamber 31, thereby driving the fixed partition 37 and the movable partition 36 to complete the batch feeding.

[0019] The working principle of this feed production tubular chain conveyor anti-blocking device will be explained in detail below.

[0020] like Figure 1-5As shown, when the device enters the working state, the drive motor 52 below the main body 1 of the tubular chain conveyor is started first. The drive motor 52, as the core power source, drives the transmission main shaft 51 connected to it to start rotating. At this time, the transmission main shaft 51 establishes two power transmission paths simultaneously through pulleys and belts on both sides, providing power to the feeding hopper assembly 4 and the indexing disc feeding mechanism 3 respectively. The top of the transmission main shaft 51 is connected to the top of the stirring shaft 42 through pulleys and belts, and the stirring shaft 42 rotates. At the same time, the transmission main shaft 51 is connected to the indexing disc rotating shaft 38 of the indexing disc feeding mechanism 3 through another set of pulleys and belts, driving the indexing disc rotating shaft 38 to rotate above the feeding cavity 31. The fixed part above the feeding cavity 31 is fixed. The seat 32 is rotatably connected to the transmission main shaft 51, providing support for the transmission main shaft 51 and preventing it from shifting during high-speed rotation, thus ensuring the stability of power transmission. The operator puts the feed material to be conveyed into the feed hopper body 41 of the feed hopper assembly 4. At this time, the feed hopper body 41 serves as a temporary storage and pre-processing space for the material, preventing the material from directly impacting subsequent mechanisms. As the stirring shaft 42 rotates synchronously inside the feed hopper body 41, the blades of the stirring shaft 42 continuously agitate the material, breaking down the agglomerated structure formed by the viscosity of oil and moisture, while preventing the material from forming a stable arched blockage layer at the bottom of the feed hopper body 41, ensuring that the material enters the feed chamber cover 311 in a loose and uniform state. The material flows smoothly through the feed inlet, reducing the risk of blockage. After being dispersed by the stirring shaft 42, the material flows out from the outlet at the bottom of the feed hopper body 41 and falls into the feed chamber 31 of the indexing disc type feeding mechanism 3 through the pre-set feed inlet above the feed chamber cover 311. At this time, the feed chamber 31 and the feed chamber cover 311 together form a sealed feeding space to prevent material from spilling or being contaminated by the outside during the conveying process. Since the indexing disc rotating shaft 38 is fixedly connected to the fixed partition 37, the rotation of the indexing disc rotating shaft 38 will synchronously drive the fixed partition 37 to rotate in the feed chamber 31. The fixed partition 37 divides the material in the feed chamber 31 into several independent temporary material compartments. As the fixed partition 37 rotates, these material compartments... The material will be carried towards the outlet of the feeding chamber 31 to achieve initial batch conveying of the material and avoid a large amount of material flowing into the subsequent channel at one time. When it is necessary to convey feed with high fine powder content and avoid accumulation, the operator can open the inspection cover 33 above the feeding chamber cover 311 and remove the partition positioning pin 34 that is clipped between the fixed plate 35 and the movable partition 36. Then, press the fixed plate 35, which is fixed to the indexing plate shaft 38 to keep the position stable. Move the partition adjustment lever 39 above the movable partition 36 to make the partition sliding guide rail 310 on the inner side of the movable partition 36 slide outward along the sliding groove on the inner side of the fixed partition 37 until the movable partition 36 and the fixed partition 37 form more fine material compartments.Finally, reinsert the partition positioning pin 34, causing the partition adjusting block 39 to engage with the slot on the outside of the partition positioning pin 34, fixing the position of the movable partition 36. At this point, the number of material compartments increases, and the volume of each compartment decreases, allowing materials to be conveyed in small batches at a high frequency. When conveying granular feed to improve efficiency, reverse the above operation to push the movable partition 36 closer to the fixed partition 37, reducing the number of material compartments and increasing the volume of each compartment, thus switching to a high-efficiency conveying mode. When the material grid formed by plates 37 rotates to the outlet of the feeding chamber 31, the material in the grid falls into the feed transition frame 2, which is fixedly connected to the outlet of the feeding chamber 31, under the action of gravity. The feed transition frame 2 acts as a buffer and guide channel to prevent the material from directly impacting the inlet of the tubular chain conveyor body 1, and at the same time guides the material into the tubular chain conveyor body 1. The material entering the tubular chain conveyor body 1 is continuously conveyed forward by the tubular chain components that circulate inside the conveyor, and delivered to the next stage of feed production.
