It is widely used in the transportation of materials in various industrial and mining enterprises. It can realize continuous operation, low noise, large transportation capacity, no strict requirements on particle size, long transportation distance, low energy consumption, simple structure and easy maintenance. In the actual production process, due to the deviation of the belt conveyor and the accumulation of materials on the end face of the lower belt, the belt conveyor tail wheel and the belt are blocked, which in turn affects the normal operation of the production equipment, resulting in shutdown accidents and equipment damage.

[0003] In the related art, a rotating shaft and a rotatable baffle are set on the belt conveyor, and the position of the baffle is detected by a sensor to monitor the material spillage. When the belt conveyor spills material, the material will push the baffle to rotate, causing the sensor to detect the change in the position of the baffle, thus stopping the belt conveyor and allowing staff to deal with the spilled material. However, when the volume of the spilled material is large, it is easy to impact the baffle and the rotating shaft, causing damage to the detection structure. Summary of the invention

[0008] Optionally, the anti-piling device further comprises an elastic member, wherein the elastic member is connected to the rotating sleeve and / or the baffle plate to reset the baffle plate.

[0009] Optionally, the number of the sawtooth structures is set to be multiple and arranged around the circumference of the vertical shaft, the sawtooth structure includes a ratchet portion and a recessed portion, the ratchet portion is provided on one of the vertical shaft and the rotating sleeve, the recessed portion is provided on the other of the vertical shaft and the rotating sleeve, a limiting portion is formed between two adjacent sawtooth structures, the rotating sleeve rotates with the baffle so that one of the recessed portions can move from the corresponding ratchet portion to the next ratchet portion, and the limiting portion is used to stop the rotation of the rotating sleeve.

[0010] Optionally, the anti-piling device further includes a detector and a controller, wherein the detector is used to detect the position of the baffle, the controller is connected to the detector signal, and the controller is used to control the start and stop of the conveyor belt.

[0015] Through the above technical solution, when the conveyor conveys materials through the conveyor belt, the materials on the feeding section may fall onto the return section. At this time, the materials are stopped by the baffle when they move with the return section to the anti-stacking device, so as to reduce the possibility that this part of the materials moves with the return section and is blocked between the support and the conveyor belt of the conveyor, thereby hindering the normal conveying operation of the conveyor. In addition, the baffle can rotate around the pivot axis, and the pivot axis is perpendicular to the belt surface of the return section, so that when the larger material is stopped by the baffle, it will not directly impact the rotating shaft of the baffle, thereby reducing the possibility that the material hits the rotating shaft of the baffle and causes damage to the rotating shaft, making it impossible for the baffle to rotate normally. At the same time, the larger material can push the baffle to rotate, so that the rotation of the baffle can buffer the impact of the material and protect the baffle's own structure.

[0019] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0020] In the present disclosure, unless otherwise stated, "inside" and "outside" refer to the inside and outside of the outline of the corresponding component; "far" and "near" refer to the distance and nearness of the corresponding component in space relative to another component. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another element and do not have order and importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] The anti-piling device and the conveyor 1 in the exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0022] According to the first aspect of the present disclosure, referring to Figures 1 to 3 The present disclosure provides an anti-piling device, which is applied to a conveyor 1. The conveyor 1 includes a conveyor belt 11. The conveyor belt 11 includes a feed section and a return section 111 located below the feed section. The anti-piling device includes a baffle 2 rotatable around a pivot axis. The baffle 2 is arranged between the feed section and the return section 111, wherein the pivot axis is perpendicular to the belt surface of the return section 111.

[0023] In an exemplary application scenario, the anti-piling device is installed on a conveyor 1, and the conveyor 1 may include, for example, a belt conveyor 1 or a chain conveyor 1, wherein the conveyor 1 includes a bracket 12 and a conveyor belt 11 disposed on the bracket 12, and the conveyor belt 11 includes a feeding section for conveying materials and a return section 111 located below the feeding section, and the conveyor belt 11 can be circulated on the bracket 12 through rollers so as to be used to transport materials. However, in the process of conveying materials in the conveying section, the materials may fall to the return section 111 due to vibration or collision, and in the process of the movement of the return section 111, the materials may hit the structures of the conveyor 1 such as the bracket 12 or the rollers, or when the materials move to the junction of the return section 111 and the feeding section, they are easily accumulated to block between the bracket 12 and the conveyor belt 11, affecting the normal feeding operation of the conveyor 1.

[0024] Through the above technical solution, when the conveyor 1 conveys materials through the conveyor belt 11, the materials on the feeding section may fall onto the return section 111. At this time, the materials are stopped by the baffle 2 when they move with the return section 111 to the anti-piling device, so as to reduce the possibility that the part of the materials moves with the return section 111 and is blocked between the support 12 of the conveyor 1 and the conveyor belt 11, thereby hindering the normal conveying work of the conveyor 1. In addition, the baffle 2 can rotate around the pivot axis, and the pivot axis is perpendicular to the belt surface of the return section 111, so that when the larger volume of materials is stopped by the baffle 2, it will not directly impact the rotating shaft of the baffle 2, thereby reducing the possibility that the materials hit the rotating shaft of the baffle 2 and cause damage to the rotating shaft, so that the baffle 2 cannot rotate normally. At the same time, the larger volume of materials can push the baffle 2 to rotate, so that the impact of the materials can be buffered by the rotation of the baffle 2 and the structure of the baffle 2 can be protected.

[0025] In some embodiments, reference Figure 1 The anti-piling device may further include a detector 8 and a controller. The detector 8 is used to detect the position of the baffle 2. The controller is connected to the detector 8 by signal, and the controller is used to control the start and stop of the conveyor belt, so that the conveyor 1 can be stopped by the controller when the baffle 2 rotates to the set position. In this way, when the material falling on the return section 111 can push the baffle 2 to rotate to the set position, the detector 8 detects the position of the baffle 2 and transmits the signal to the controller, and then the conveyor 1 is braked by the controller to reduce the possibility that the part of the material continues to move with the return section 111 and is blocked between the support 12 of the conveyor frame and the conveyor belt 11, or hits the support 12 to affect the normal feeding of the conveyor 1.

[0026] The detector 8 can be constructed in any suitable manner. For example, the detector 8 can include a proximity switch, and the baffle 2 is constructed as a metal plate for proximity switch detection. In this case, the proximity switch can be constructed as an inductive proximity switch. The inductive proximity switch is based on the principle of electromagnetic induction, and has a high-frequency oscillation coil and a detection coil disposed therein. When the baffle 2 approaches, it interferes with the electromagnetic field around the coil, causing the amplitude or frequency of the oscillation circuit to change, thereby triggering a switch signal. Of course, a metal sheet can also be disposed on the baffle 2 for proximity switch detection, and the present disclosure does not specifically limit this.

[0027] It is understandable that the proximity switch can also be constructed as a photoelectric proximity switch, which includes a light source (usually an infrared LED or laser) and a photoelectric receiver. When the baffle 2 enters between the light source and the receiver, the light is blocked or reflected by the baffle 2, and the receiver detects the change in light intensity, thereby triggering a switch signal. Of course, the detector 8 can also include a capacitive sensor, an ultrasonic sensor, or a visual sensor, etc., and the present disclosure is not limited thereto.

[0028] In some embodiments, reference Figure 1 and Figure 2 The anti-piling device may further include a vertical shaft 3 and a rotating sleeve 4 sleeved on the vertical shaft 3, and the baffle 2 is connected to the rotating sleeve 4, so that the baffle 2 can rotate relative to the vertical shaft 3 through the rotating sleeve 4. At the same time, the central axis of the vertical shaft 3 is the above-mentioned pivot axis, so that the baffle 2 can rotate around the pivot axis.

[0029] In addition, reference Figure 2 and Figure 3 A sawtooth structure 5 is provided between the rotating sleeve 4 and the vertical shaft 3, wherein the sawtooth structure 5 can provide resistance to limit the rotation of the baffle 2. In this way, when the material falling onto the return section 111 is small, this part of the material is stopped by the baffle 2, and at this time the sawtooth structure 5 can provide resistance to limit the rotation of the baffle 2 toward the moving direction of the return section 111. The thrust of this part of the material moving with the return section 111 to drive the baffle 2 to rotate is less than the resistance of the sawtooth structure 5 to limit the rotation of the baffle 2. At this time, the baffle 2 will not rotate or rotate at a small angle, so that this part of the material will not affect the feeding work of the conveyor 1, and the conveyor 1 will not stop due to the small part of the material falling, so that it can continue to work and reduce the economic loss caused by the stoppage.

[0030] When the material dropped onto the return section 111 is large, this part of the material is stopped by the baffle 2. However, at this time, the thrust of the larger part of the material moving with the return section 111 to drive the baffle 2 to rotate is greater than the resistance of the serrated structure 5 to limit the rotation of the baffle 2. At this time, the baffle 2 rotates toward the moving direction of the return section 111, and then the detector 8 detects the position change of the baffle 2, and stops the conveyor 1 through the controller when the baffle 2 rotates to the set position, so as to reduce the possibility that this part of the material continues to move with the return section 111 and is blocked between the bracket 12 of the conveyor frame and the conveyor belt 11, or hits the bracket 12 to affect the normal feeding of the conveyor 1.

[0031] In addition, the sawtooth structure 5 can provide resistance to limit the baffle 2 from rotating in the moving direction away from the return section 111, so as to be used to maintain the position of the baffle 2 after the position of the baffle 2 is changed, so that the staff can observe the position of the baffle 2 to find the reason for the shutdown of the conveyor 1. That is, when the conveyor 1 is shut down, the baffle 2 rotates to the set position, and the reason for the shutdown of the conveyor 1 is that the large volume of materials pushes the baffle 2 to rotate. At this time, after the staff cleans the materials on the return section 111 and confirms that there are no other problems with the conveyor 1, the conveyor 1 can be started; when the conveyor 1 is shut down, the baffle 2 is still in the initial position, and the staff needs to check the reason for the shutdown separately. It can be understood that at this time, the cause of the shutdown can be quickly judged, which reduces the maintenance burden of the staff and reduces the shutdown loss.

[0032] In some embodiments, reference Figure 3The sawtooth structure 5 may include a ratchet portion 51 and a recessed portion 52, wherein the ratchet portion 51 is disposed on one of the vertical shaft 3 and the rotating sleeve 4, and the recessed portion 52 is disposed on the other of the vertical shaft 3 and the rotating sleeve 4. The present disclosure exemplarily disposes the ratchet portion 51 on the vertical shaft 3 and the recessed portion 52 on the rotating sleeve 4. Of course, in some other possible alternative embodiments not shown in the drawings, the ratchet portion 51 may be disposed on the rotating sleeve 4, and the recessed portion 52 may be disposed on the vertical shaft 3, and the present disclosure is not limited thereto.

[0033] The ratchet portion 51 contacts the recessed portion 52 to form an inclined section 53, so that the rotating sleeve 4 is configured as follows: the rotating sleeve 4 can rotate with the baffle 2 and move upward or downward along the central axis of the vertical shaft 3 under the guidance of the inclined section 53. The upward movement of the rotating sleeve 4 can make the rotating sleeve 4 rotate circumferentially relative to the vertical shaft 3 by at least one circumferential angle occupied by the ratchet portion 51 or the recessed portion 52. The downward movement of the rotating sleeve 4 can make the rotating sleeve 4 rotate circumferentially relative to the vertical shaft 3 until it is reset. It should be noted that the upper side of the rotating sleeve 4 when it moves upward can refer to Figure 2 and Figure 3 The upper part of the drawing direction, at this time, the height of the rotating sleeve 4 and the baffle 2 increases, and the lower part when the rotating sleeve 4 moves downward can be referred to Figure 2 and Figure 3 The height of the rotating sleeve 4 and the baffle 2 is lowered in the direction of the drawing. In this way, when the material pushes the baffle 2 to rotate in the moving direction of the return section 111, the rotating sleeve 4 moves upward to change the position of the recessed portion 52 relative to the ratchet portion 51, and the height of the rotating sleeve 4 and the baffle 2 increases. At this time, the gravity of the rotating sleeve 4 and the baffle 2 provides resistance to limit the continued rotation of the baffle 2. When the material pushes the baffle 2 to continue to rotate, the rotating sleeve 4 can be rotated relative to the vertical shaft 3 along the circumferential direction by at least one circumferential angle occupied by the ratchet portion 51 or the recessed portion 52, until the baffle 2 rotates to the set position and triggers the shutdown. In addition, when the material pushes the baffle 2 to rotate and the height of the baffle 2 and the rotating sleeve 4 is increased, a gap will be generated between the baffle 2 and the surface of the return section 111, so that some small materials that are not enough to affect the normal operation of the conveyor belt will pass through the gap, thereby reducing the thrust of the material on the baffle 2. When it is reduced to a certain extent, the baffle 2 and the rotating sleeve 4 may move downward along the inclined section 53 under the action of their own gravity, thereby resetting.

[0034] In some embodiments, reference Figure 1The anti-piling device may further include an elastic member 7, which is connected to the rotating sleeve 4 and / or the baffle 2 to reset the baffle 2. In this way, when the material pushes the baffle 2 to rotate in the moving direction of the return section 111, the elastic member 7 cooperates with the sawtooth structure 5 to provide an elastic force for the baffle 2 to rotate in the moving direction away from the return section 111, and this part of the elastic force provides resistance to limit the continued rotation of the baffle 2. Therefore, by adding the elastic member 7, the force required for the material to push the baffle 2 to move can be increased. Therefore, the elastic force of the elastic member 7 can be designed according to actual application requirements, for example, according to the weight / size of the material that can affect the normal operation of the conveyor.

[0035] It can be understood that the elastic member 7 can be constructed as, for example, a spring or an elastic band. The present disclosure exemplarily connects the elastic member 7 between the bracket 12 and the baffle 2 of the conveyor 1. Of course, in some other possible alternative embodiments not shown in the accompanying drawings, the elastic member 7 can also be connected between the bracket 12 and the rotating sleeve 4 of the conveyor 1. In addition, the number of elastic members 7 can also be set to multiple, and they are respectively connected between the bracket 12 and the baffle 2 of the conveyor 1 and between the bracket 12 and the rotating sleeve 4 of the conveyor 1. The present disclosure does not make specific limitations on this.

[0036] In some embodiments, reference Figure 3 The number of the sawtooth structures 5 can be set to multiple and arranged around the circumference of the vertical shaft 3. The sawtooth structure 5 includes a ratchet portion 51 and a recessed portion 52. The ratchet portion 51 is provided on one of the vertical shaft 3 and the rotating sleeve 4, and the recessed portion 52 is provided on the other of the vertical shaft 3 and the rotating sleeve 4. The present disclosure exemplarily provides the ratchet portion 51 on the vertical shaft 3 and the recessed portion 52 on the rotating sleeve 4. Of course, in some other possible alternative embodiments not shown in the drawings, the ratchet portion 51 can be provided on the rotating sleeve 4, and the recessed portion 52 can be provided on the vertical shaft 3.

[0037] In addition, a limiting portion 6 is formed between two adjacent sawtooth structures 5, and the rotating sleeve 4 rotates with the baffle 2 so that one of the recessed portions 52 can move from the corresponding ratchet portion 51 to the next ratchet portion 51, and the limiting portion 6 is used to stop the rotation of the rotating sleeve 4. The ratchet portion 51 includes a first inclined section and a first straight section, and the recessed portion 52 includes a second inclined section and a second straight section. The first inclined section and the second inclined section contact and cooperate to form an inclined section 53, and the first straight section and the second straight section contact and cooperate to form the limiting portion 6. It should be noted that the extension direction of the first straight section and the second straight section is parallel to the above-mentioned pivot axis, so that at this time the second straight section stops the movement of the first straight section away from the transmission direction of the return section 111, that is, to stop the baffle 2 from rotating away from the moving direction of the return section 111, so as to be used to keep the baffle 2 in the position after rotation or the position after reset.

[0038] In some embodiments, reference Figure 1 The anti-piling device may further include a limit column 9, which is used to limit the rotation stroke of the baffle 2. In this way, when the volume or quantity of the materials dropped on the return section 111 is large, the driving force of the materials to push the baffle 2 to rotate is large. At this time, the baffle 2 is stopped by the limit column 9 to reduce the possibility that the baffle 2 rotates too much and hits the bracket 12 of the conveyor 1 or causes harm to the staff, thereby improving the working safety of the overall anti-piling device.

[0039] Among them, the limiting column 9 can be constructed as a metal rod or a rubber rod and exemplarily connected to the bracket 12 of the conveyor 1. Of course, the cross-section of the limiting column 9 can be constructed as a square, circular or polygonal shape, etc., and the present disclosure does not make specific limitations on this.

[0040] According to a second aspect of the present disclosure, a conveyor 1 is provided, comprising a support 12, a conveyor belt 11 disposed on the support 12, and the anti-piling device as described above, wherein the conveyor belt 11 comprises a feeding section and a return section 111 located below the feeding section. The conveyor 1 has all the beneficial effects of the anti-piling device described above, and the conveyor 1 may comprise, for example, a belt conveyor 1 or a chain conveyor 1, etc., which will not be described in detail in the present disclosure.

[0041] It can be understood that part of the structure of the anti-piling device can be connected to the bracket 12. For example, the vertical shaft 3 can be connected to the bracket 12, the baffle 2 is connected to the vertical shaft 3 through a rotating shaft and extends to the top of the return section 111, the proximity switch can be connected to the bracket 12 through, for example, a support rod, and one end of the elastic member 7 can be connected to the bracket 12 to reduce the space occupied by the anti-piling device. Of course, the above-mentioned vertical shaft 3, support rod and elastic member 7 can also be connected to the ground, but the present disclosure is not limited to this.

[0042] In some embodiments, reference Figure 2 The number of anti-piling devices can be set to multiple to improve the protection safety of the conveyor 1. For example, multiple anti-piling devices can be arranged at intervals along the transmission direction of the conveyor belt 11. For example, the number of anti-piling devices can be set to two. In this way, when a large volume or a large number of materials fall onto the return section 111, if the conveying speed of the return section 111 is faster, the baffle 2 of the first anti-piling device is pushed by the material and rotates to a position that can be detected by the detector 8. At this time, the conveyor belt 11 is stopped by the controller. This part of the material may continue to move under the action of inertia. Therefore, the second anti-piling device can stop this part of the material to reduce the possibility of this part of the material damaging the structure of the conveyor 1.

[0043] Alternatively, a plurality of anti-piling devices may be arranged in pairs on opposite sides of the conveyor belt 11, with the connecting line of the two pairs of anti-piling devices being perpendicular to the pivot axis. For example, the number of anti-piling devices may be set to two, and at this time the baffles 2 of the two anti-piling devices jointly act to stop the material that falls onto the return section 111, thereby improving the stopping ability for the material. At this time, this part of the material will not affect the feeding operation of the conveyor 1, and the conveyor 1 will not stop due to the small part of the material that falls, so that it can continue to work and reduce the economic losses caused by the stoppage.

[0044] It is understandable that the number of the anti-piling devices may also be set to three, four or five, etc., and the arrangement of multiple anti-piling devices may adopt at least one of the above arrangements, which is not specifically limited in the present disclosure.

[0045] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0047] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
