Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor equipment, specifically to a belt conveyor buffer receiving device that can adjust the material drop point. Background Technology

[0002] Conveyor belt misalignment is a common equipment failure during belt conveyor operation. Misalignment can lead to problems such as material spillage, belt edge wear, belt jamming, and tearing, preventing the belt conveyor from operating normally and severely impacting system production. There are many causes of misalignment, among which the location of the material drop point at the receiving end and the impact force of the material discharge have a significant impact on conveyor belt misalignment, and it is difficult to correct using ordinary anti-misalignment devices such as adjusting rollers.

[0003] In recent years, adjustable material receiving devices for belt conveyors have been developed in existing technologies. These devices can solve belt conveyor deviation caused by misalignment of the material drop point by adjusting the drop point position. However, they neglect the impact of high-speed material flow impact on deviation. When material falls at each transfer point, it generates a large impact force on the receiving point of the belt conveyor, causing the belt conveyor to vibrate. Especially in conditions such as intermittent material feeding from the top of a lime kiln, the reciprocating vibration of the belt conveyor during operation is large, causing radial runout of the conveyor belt and resulting in belt deviation.

[0004] In summary, there is an urgent need for a belt conveyor buffer receiving device that can adjust the material drop point to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a belt conveyor buffer receiving device that can adjust the material drop point, aiming to solve the problem of belt conveyor deviation caused by incorrect material drop point position and high-speed material flow impact. The specific technical solution is as follows:

[0006] A belt conveyor buffer receiving device with adjustable material drop point includes an upper trough, a lower trough, guide plates, an adjusting device, and a buffer distributor. The lower trough is located below the upper trough and the two are interconnected. The buffer distributor is located inside the lower trough and is located directly below the discharge port of the upper trough. Guide plates are arranged on both sides of the buffer distributor in the lower trough. The upper end of the guide plate is rotatably connected to the lower trough and the guide plate is driven to swing by the adjusting device.

[0007] Preferably, the cross-section of the buffer fabric distributor is an inverted V-shaped structure; the guide plates are symmetrically arranged on both sides of the buffer fabric distributor.

[0008] Preferably, the upper tank, lower tank, guide plate, and buffer distributor all have a wear-resistant layer on the side that contacts the material.

[0009] Preferably, the upper end of the guide plate is provided with a rotating shaft, the lower trough is provided with a rotating shaft seat, and the rotating shaft is rotatably disposed in the rotating shaft seat.

[0010] Preferably, the upper tank has a connecting flange one at its inlet; the lower tank has a connecting flange two at its inlet, and the upper tank's outlet is connected to the connecting flange two.

[0011] Preferably, the lower tank body has at least one observation window on the connecting flange.

[0012] Preferably, the adjusting device includes a handle, a lead screw, a connecting rod, and a mounting sleeve; one end of the lead screw is provided with a handle, and the other end is provided with a ball head; one end of the connecting rod is hinged to the guide plate, and the other end is provided with a ball socket; the mounting sleeve is disposed on the lower trough and is provided with a threaded hole thereon; the lead screw and the mounting sleeve are threadedly connected, and the ball head is located inside the lower trough and disposed in the ball socket.

[0013] Preferably, the adjusting device includes a handle, a lead screw, a roller, and a mounting sleeve; one end of the lead screw is provided with a handle, and the other end is rotatably provided with a roller; the mounting sleeve is disposed on the lower groove body and is provided with a threaded hole thereon, the lead screw and the mounting sleeve are threadedly connected, and the roller is in rolling contact with the guide plate.

[0014] Preferably, the adjusting device further includes a limiting spring, which is sleeved on the lead screw, with one end of the limiting spring pressing against the handle and the other end pressing against the mounting sleeve.

[0015] Preferably, the mounting sleeve includes a fixed sleeve and a limiting sleeve. The fixed sleeve is fixedly mounted on the lower groove body, and the limiting sleeve is fixedly connected to the fixed sleeve. Between the limiting sleeve and the fixed sleeve, one has a through hole and the other has a threaded hole.

[0016] The application of the technical solution of this utility model has the following beneficial effects:

[0017] This utility model discloses a belt conveyor buffer receiving device with adjustable material drop point, which can solve the problem of belt conveyor deviation caused by improper material drop point position and high-speed material flow impact. By adjusting the swing angle of the guide plate, the position of the material drop point can be adjusted, thus solving the problem of conveyor belt deviation caused by improper material drop point position. At the same time, the buffer distributor inside the lower trough can buffer and decelerate the high-speed material flow. In conjunction with the inclined guide plate, the inclined upper trough, and the wall plate of the lower trough, it can achieve the effect of material gathering and buffering, preventing the high-speed material flow from directly impacting the belt conveyor and solving the problem of belt conveyor deviation caused by high-speed material flow impact.

[0018] In this invention, the adjusting device is equipped with a limiting spring. The limiting spring in the compressed state provides an elastic force that makes the external thread on the lead screw fit tightly with the internal thread in the mounting sleeve, so as to prevent the lead screw from rotating on its own. At the same time, the elastic force can also eliminate the gap between the threads, so as to provide stable support for the guide plate.

[0026] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Example:

[0029] See Figures 1-3 This embodiment provides a belt conveyor buffer receiving device with adjustable material drop point, including an upper trough 1, a lower trough 3, guide plates 4, an adjusting device 7, and a buffer distributor 8; the lower trough 3 is located below the upper trough 1 and the two are interconnected; the buffer distributor 8 is located inside the lower trough 3 and is located directly below the discharge port of the upper trough 1; guide plates 4 are arranged on both sides of the buffer distributor 8 in the lower trough 3; the upper end of a single guide plate 4 is rotatably connected to the lower trough 3, and the lower end of the guide plate 4 is connected to the adjusting device 7, which drives the guide plate 4 to swing (i.e., the guide plates on both sides are driven to swing by the corresponding adjusting devices 7).

[0030] Furthermore, a conveyor belt guide trough 11 is provided below the lower trough 3. The material flows through the upper trough and the lower trough in sequence and then enters the conveyor belt guide trough 11. Furthermore, the cross-section of the buffer distributor 8 is an inverted V-shaped structure. After the material in the upper trough 1 enters the lower trough 3, it falls onto the buffer distributor 8, thereby slowing down, dispersing and uniformly distributing the material flow, and reducing the direct impact of the material flow on the conveyor belt.

[0031] Preferably, the guide plates 4 are arranged symmetrically on both sides of the buffer distributor 8, and the guide plates 4 on both sides of the buffer distributor 8 form a V-shaped structure. After the buffer distributor divides the material into two streams, the two streams fall onto the guide plates on both sides respectively. The swing angle of the guide plates 4 is adjusted by the adjustment device 7 on both sides, thereby adjusting the drop point.

[0032] Preferably, in this embodiment, both the upper tank 1 and the lower tank 3 are frustum structures. The upper tank 1 is configured as a frustum structure to achieve material convergence and primary buffering. Similarly, the lower tank 3, configured as a frustum structure in conjunction with the guide plate, can also achieve material convergence and buffering.

[0033] Preferably, the upper tank 1, lower tank 3, guide plate 4, and buffer distributor 8 are all provided with a wear-resistant layer on the side that contacts the material, thereby preventing the material from eroding the upper tank, lower tank, guide plate, and buffer distributor, and extending the service life of the device; furthermore, in this embodiment, the wear-resistant layer is a wear-resistant liner, and the wear-resistant liner is installed in a detachable manner for easy maintenance and replacement.

[0034] Preferably, in this embodiment, the upper end of the guide plate 4 is provided with a rotating shaft 5, and the lower tank 3 is provided with a rotating shaft seat 6. The rotating shaft 5 is rotatably disposed in the rotating shaft seat 6, thereby enabling the guide plate 4 to swing around its upper end inside the lower tank 3. Further, the rotating shaft 5 can be a single shaft welded to the upper end of the guide plate 4, with both ends of the shaft 5 rotatably disposed in the rotating shaft seat 6. Alternatively, columnar bodies can be machined on both sides of the upper end of the guide plate 4 as rotating shafts, with the two rotating shafts rotatably disposed in the rotating shaft seat 6 respectively, to achieve the effect of the guide plate rotating (i.e., swinging) around its upper end. Further, the rotating shaft seat 6 is provided with a bearing, the outer ring of which is fixedly installed in the rotating shaft seat 6, and the inner ring of which is fixedly connected to the rotating shaft 5 (i.e., interference fit).

[0035] Preferably, the upper tank 1 is provided with a connecting flange 2 at its inlet, which is used to connect the upper tank 1 to the outlet of the feeding device; the lower tank 3 is provided with a connecting flange 9 at its inlet, and the outlet of the upper tank 1 is connected to the connecting flange 9; using flanges for connection facilitates disassembly and reassembly during subsequent maintenance.

[0036] Preferably, the lower tank 3 is provided with at least one observation window 10 on the connecting flange 9. The observation window 10 allows observation of the material drop point position and the working status of the guide plate, facilitating timely maintenance and adjustment of the material drop point. Furthermore, to facilitate observation of the working status of the guide plate, in this embodiment, the observation window is preferably located directly above the guide plate, and the number of observation windows is two.

[0037] See Figures 1-3In this embodiment, the adjusting device 7 includes a handle 7.1, a lead screw 7.6, a connecting rod 7.7, and a mounting sleeve. One end of the lead screw 7.6 is provided with a handle 7.1, and the other end is provided with a ball head. One end of the connecting rod 7.7 is hinged to the guide plate 4, and the other end is provided with a ball socket. The mounting sleeve is disposed on the lower groove 3 and is provided with a threaded hole. The lead screw is provided with an external thread. The lead screw 7.6 and the mounting sleeve are threadedly connected, and the ball head is located inside the lower groove 3. The ball head is disposed in the ball socket (i.e., the ball head and the ball socket form a joint bearing). During adjustment, rotating the lead screw 7.6 allows it to extend into or retract from the lower trough 3. Since the lead screw 7.6 and the connecting rod 7.7 form a joint bearing, the lead screw 7.6 will not drive the connecting rod 7.7 to rotate. At the same time, the connecting rod 7.7 is hinged to the guide plate 4, so the translation of the lead screw can be converted into the oscillation of the guide plate, thereby achieving the effect of adjusting the material drop point.

[0038] Furthermore, the adjusting device 7 also includes a limiting spring 7.3, which is sleeved on the lead screw 7.6. One end of the limiting spring 7.3 abuts against the handle 7.1, and the other end abuts against the mounting sleeve. When the limiting spring 7.3 is in operation, it is in a compressed state. The compressed limiting spring 7.3 provides an elastic force that ensures the external thread on the lead screw 7.6 is tightly engaged with the internal thread in the mounting sleeve, preventing the lead screw from rotating. At the same time, this elastic force can also eliminate the gap between the threads, providing stable support for the guide plate.

[0039] See Figure 3 The mounting sleeve includes a fixed sleeve 7.5 and a limiting sleeve 7.4. The fixed sleeve 7.5 is fixedly mounted on the lower groove body 3. The limiting sleeve 7.4 is fixedly connected to the fixed sleeve 7.5. Between the limiting sleeve 7.4 and the fixed sleeve 7.5, one has a through hole and the other has a threaded hole. The lead screw passes through the limiting sleeve 7.4 and the fixed sleeve 7.5 in sequence and then extends into the interior of the lower groove body. The lead screw 7.6 has a limiting end plate 7.2 at one end near the handle. The two ends of the limiting spring 7.3 respectively abut against the limiting end plate 7.2 and the limiting sleeve 7.4.

[0040] See Figure 4 In this embodiment, another structural form of the adjusting device 7 is also provided. The adjusting device 7 includes a handle 7.1, a lead screw 7.6, a roller 7.8, and a mounting sleeve. One end of the lead screw 7.6 is provided with a handle 7.1, and the other end is rotatably provided with a roller 7.8. The mounting sleeve is disposed on the lower groove 3 and is provided with a threaded hole. The lead screw 7.6 and the mounting sleeve are threadedly connected, and the roller 7.8 is in rolling contact with the guide plate 4.

[0041] Furthermore, in Figure 4 In the structure of the adjustment device shown, the end of the lead screw 7.6 can be provided with a groove for mounting the roller 7.8. The roller 7.8 is disposed in the groove and mounted on the lead screw 7.6 by a pin (the roller can be rotatably mounted on the pin by a bearing). After the roller 7.8 is installed, its axis is perpendicular to the axis of the lead screw. When the lead screw is rotated and screwed into the interior of the lower groove, it can push the guide plate to swing. The guide plate and the roller 7.8 are in rolling contact, which can satisfy the degree of freedom required for the swing of the guide plate. When the lead screw is screwed out from the interior of the lower groove, the guide plate will move with the roller due to its own weight, that is, the guide plate and the roller will not separate.

[0042] exist Figure 4 The adjustment device structure shown also includes a mounting sleeve and a limiting spring 7.3. The specific arrangement of the mounting sleeve and the limiting spring 7.3 is the same as... Figure 3 The structural form of the adjustment device shown is the same, so it will not be described again.

[0043] Preferably, in some embodiments, the adjusting device 7 may be a telescopic device such as a cylinder or hydraulic cylinder. One end of the adjusting device is hinged to the inside of the lower tank, and the other end is hinged to the guide plate. By extending and retracting the adjusting device, the swing angle of the guide plate can be adjusted, thereby achieving the effect of adjusting the material drop point.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
