Description

Technical Field

[0001] This application relates to the technical field of unloading plow equipment, and particularly to a device for detecting the pressing degree of an unloading plow. Background Art

[0002] An unloading plow is a component used on a multi-point unloading belt conveyor to achieve multi-point intermediate unloading of the belt conveyor. The principle of its multi-point unloading is to flatten the belt with material and then lower the unloading plow, making the unloading plow closely adhere to the conveyor belt. After the material collides with the unloading plow, it will move along the shape direction of the unloading plow, and finally the material is swept into the chute on both sides of the conveyor belt.

[0003] During the use of the unloading plow, usually the plow blade of the unloading plow is pressed on the conveyor belt, and the movement of the conveyor belt drives the material to move to both sides of the unloading plow. However, when adjusting the pressing of the plow blade on the conveyor belt, it is impossible to accurately judge the pressing degree between the plow blade and the conveyor belt. If the pressing is too loose, the material will enter the gap between the secondary plow and the conveyor belt and get stuck in this gap. The conveyor belt will drag the unloading plow down through the stuck material, and the support plate and the unloading plow are likely to lock the conveyor belt, and the driving motor of the belt conveyor cannot drag the conveyor belt, resulting in overload damage to the power system for driving the conveyor belt and damage to the power system for driving the unloading plow. If the pressing is too tight, the friction between the plow blade and the conveyor belt will be too large, increasing the load of the conveyor belt and also accelerating the wear of the plow blade. Summary of the Utility Model

[0004] In order to improve the convenience of the unloading plow during use, this application provides a device for detecting the pressing degree of the unloading plow.

[0005] This application provides a device for detecting the pressing degree of an unloading plow, adopting the following technical solution:

[0006] The device for detecting the pressing degree of the unloading plow includes a frame. A guiding frame for placing the conveyor belt is installed on the frame. An unloading plow frame is installed on the frame. The unloading plow frame includes a main plow and a secondary plow. A detecting device for judging the pressing degree by the distance between the main plow and the secondary plow is installed on the unloading plow frame. A pushing device is installed on the frame, and the pushing device is connected to the unloading plow frame.

[0007] By adopting the above technical solution, placing the conveyor belt on the guiding frame is convenient for the rapid transportation of materials. Operating the pushing device to press the unloading plow frame on the conveyor belt, and judging whether the accurate pressing height with the conveyor belt is achieved through the detecting device, quickly pressing the unloading plow frame on the conveyor belt, improving the working efficiency, and the material is shunted through the unloading plow frame, realizing the rapid unloading of the material, which is beneficial to improving the convenience of the unloading plow during use.

[0008] In a specific feasible implementation, the detection device includes a pressure sensor, the pressure sensor is connected to the secondary plow, a sliding rod is slidably installed on the primary plow, the yellow safety is located above the pressure sensor, a pressure head shaft is installed at one end of the sliding rod close to the pressure sensor, the sliding rod is in contact with the pressure sensor through the pressure head shaft, a second spring is sleeved on the sliding rod, one end of the second spring is connected to the pressure head shaft, the other end of the second spring is connected to the main body, and a second limit block is installed at the end of the sliding rod away from the pressure head shaft.

[0009] By adopting the above technical solution, when the unloading plow frame is pressed down onto the conveyor belt, the primary plow is pushed close to the secondary plow by downward pressure, the primary plow squeezes the second spring, and the second spring pushes the pressure head shaft to generate pressure on the pressure sensor, so that the pressure of the primary plow on the secondary plow can be quickly judged according to the pressure sensor, and thus the tightness of the secondary plow pressing on the conveyor belt can be judged.

[0010] In a specific feasible implementation, the contact surface between the pressure head shaft and the pressure sensor is set as a spherical surface.

[0011] By adopting the above technical solution, the pressure head shaft is set as a spherical surface, changing the surface-to-surface contact with the pressure sensor to point-to-surface contact, concentrating the pressure at one point, preventing jitter during the use of the unloading plow, and the jitter of the sliding rod affecting the measurement of the pressure sensor, making the pressure measured by the pressure sensor more accurate.

[0012] In a specific feasible implementation, an adjusting device for adjusting the distance between the primary plow and the secondary plow is installed on the unloading plow frame. The adjusting device includes a fixing plate, the fixing plate is installed on the secondary plow, a lead screw is fixedly installed on the fixing plate, the lead screw is slidably connected to the primary plow, a first spring is sleeved on the lead screw, one end of the first spring is connected to the fixing plate, the other end is connected to the primary plow, and a rotating cylinder is threadedly connected to the lead screw.

[0013] By adopting the above technical solution, the distance between the primary plow and the secondary plow can be quickly adjusted by rotating the rotating cylinder. By rotating the rotating cylinder, the distance between the rotating cylinder and the primary plow can be adjusted. When the secondary plow is worn, the downward movement of the secondary plow will cause the primary plow to move closer to the rotating cylinder. By adjusting the rotating cylinder, the downward movement distance of the secondary plow when it is worn can be changed. When the downward movement of the secondary plow due to wear reaches a preset value, the primary plow abuts against the rotating cylinder, preventing the secondary plow from being continuously worn and causing a safety accident.

[0014] In a specific feasible implementation, a limit piece is installed on the rotating cylinder, a chute is opened on the limit piece, a lock hole is opened on the lead screw, a lock rod for limiting the rotating cylinder is slidably installed on the lead screw through the lock hole, a limit rod is installed on the lock rod, and a limit buckle for cooperating with the limit rod to limit the lock rod is installed on the rotating cylinder.

[0015] By adopting the above technical solution, rotating the locking rod, turning the limiting rod out of the limiting buckle, and pulling the locking rod away from the limiting piece can quickly unlock the rotating cylinder, facilitating the quick control of the rotation of the rotating cylinder. When the rotating cylinder does not need to be adjusted, inserting the locking rod into the limiting piece can prevent the rotating cylinder from rotating by itself due to the vibration during the use of the unloading plow, which poses a safety hazard.

[0016] In a specific feasible embodiment, the main plow includes a second mounting plate, a swing rod is hinged on the second mounting plate, the swing rod is connected to the pushing device, and a main plow plate for discharging materials is mounted on the second mounting plate.

[0017] By adopting the above technical solution, the swing rod is connected to the pushing device, which facilitates the pushing device to quickly press the unloading plow frame onto the conveyor belt, and the materials on the conveyor belt can be quickly unloaded through the main plow plate.

[0018] In a specific feasible embodiment, the auxiliary plow includes a first mounting plate, the first mounting plate is connected to the main plow, a connecting plate is mounted on the first mounting plate, the connecting plate is rotatably mounted on the frame, and an auxiliary plow plate for discharging materials is mounted on the first mounting plate.

[0019] In a specific feasible embodiment, a roller is mounted on the guide frame.

[0020] By adopting the above technical solution, the roller rolls along with the movement of the conveyor belt, which facilitates the transportation of materials, reduces the friction force, and thus reduces the load on the conveyor belt.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Placing the conveyor belt on the guide frame facilitates the rapid transportation of materials. Operating the pushing device to press the unloading plow frame onto the conveyor belt, and through the detection device, it is judged whether the accurate pressing height with the conveyor belt is reached, and the unloading plow frame is quickly pressed onto the conveyor belt, which improves the working efficiency. Moreover, the materials are shunted through the unloading plow frame, realizing the rapid unloading of materials, which is beneficial to improving the convenience of the unloading plow during use.

[0023] 2. Through the setting of the detection device, when the unloading plow frame is pressed onto the conveyor belt, by pressing the main plow close to the auxiliary plow, the main plow squeezes the second spring, and the second spring pushes the pressure head shaft to generate pressure on the pressure sensor, so that the pressure of the main plow on the auxiliary plow can be quickly judged according to the pressure sensor, and thus the tightness of the auxiliary plow pressed on the conveyor belt can be judged.

[0031] Embodiment:

[0032] An embodiment of the present application discloses a detection device for the pressing degree of an unloading plow. Referring to Figure 1 and Figure 2 , it includes a frame 1, a guide frame 2 for placing a conveyor belt is installed on the frame 1, a roller 21 is installed on the guide frame 2, an unloading plow frame 3 is installed on the frame 1, and a pushing device 4 for pressing the unloading plow frame 3 onto the conveyor belt is installed on the frame 1.

A connecting frame 41 is installed on the output shaft of the electric, pneumatic or electro-hydraulic push rod, and the connecting frame 41 is connected to the unloading plow frame 3. A detection device 5 for detecting the pressing degree between the unloading plow frame 3 and the conveyor belt is installed on the unloading plow frame 3.

[0033] Place the conveyor belt on the roller 21 of the guiding frame 2. The roller 21 rotates as the conveyor belt moves, facilitating the rapid transportation of materials. Operate the pushing device 4 to press the unloading plow frame 3 onto the conveyor belt. Use the detection device 5 to determine whether the unloading plow frame 3 and the conveyor belt reach the accurate pressing height. When the materials encounter the unloading plow frame 3, they are diverted, realizing the rapid unloading of materials, which is beneficial to improving the convenience of the unloading plow during use.

[0034] The unloading plow frame 3 includes a main plow 31 and a sub - plow 32. The sub - plow 32 includes a first mounting plate 321. The first mounting plate 321 is set as a triangular plate. A connecting plate 322 is fixedly installed on the side wall of the first mounting plate 321 close to the frame 1, and the connecting plate 322 is rotatably installed on the frame 1. On the side walls of the first mounting plate 321 on the other two sides, sub - plow plates 323 are fixedly installed. The sub - plow plates 323 are arranged in an A - shape along the triangular side of the first mounting plate 321.

[0035] Refer to Figure 2 、 Figure 3 and Figure 4 As shown in

[0036] An adjusting device 6 is installed on the first mounting plate 321. The first mounting plate 321 is connected to the main plow 31 through the adjusting device 6. The main plow 31 includes a second mounting plate 311. The second mounting plate 311 is installed above the first mounting plate 321 and is arranged parallel to the first mounting plate 321. A swing rod 312 is hinged on the second mounting plate 311. One end of the swing rod 312 away from the second mounting plate 311 is hinged to the connecting frame 41. A main plow plate 313 is installed on the second mounting plate 311. The main plow plate 313 and the sub - plow plates 323 are arranged in an A - shape and the included angles of the A - shapes are the same. There is a distance between the bottommost edge of the main plow plate 313 and the bottommost edge of the sub - plow plates 323, and the bottommost edge of the main plow plate 313 is higher than the bottommost edge of the sub - plow plates 323.

[0037] Refer to Figure 2 、 Figure 3 and Figure 4The adjusting device 6 includes a fixing plate 61, which is fixedly mounted on the first mounting plate 321. A screw rod 62 is fixedly mounted on the fixing plate 61. The screw rod 62 is vertically arranged. The screw rod 62 passes through the second mounting plate 311 and is slidably connected to the second mounting plate 311. A first spring 63 is sleeved on the screw rod 62. One end of the first spring 63 is fixedly connected to the fixing plate 61, and the other end of the first spring 63 is fixedly connected to the second mounting plate 311. A rotating cylinder 64 is threadedly connected to the screw rod 62. The rotating cylinder 64 is arranged on a side away from the first mounting plate 321. A limiting plate 65 is fixedly mounted on the rotating cylinder 64. A sliding groove 651 is provided on the limiting plate 65. A locking hole 621 is provided on the screw rod 62, and a locking rod 66 is slidably installed on the screw rod 62 through the locking hole 621. A limiting rod 67 is fixedly installed on one end of the locking rod 66. A limiting buckle 68 that cooperates with the limiting rod 67 for fixing is fixedly installed on the rotating drum 64, and the limiting buckle 68 is arranged opposite to the limiting plate 65.

[0038] When the auxiliary plowboard 323 is pressed against the conveyor belt, a distance will be left between the second mounting plate 311 and the rotating drum 64 due to the pressure of the pushing device 4. When the auxiliary plowboard 323 is pressed against the conveyor belt for a long time, wear will occur between the auxiliary plowboard 323 and the conveyor belt. The auxiliary plowboard 323 drives the rotating drum 64 to move closer to the conveyor belt, and the distance between the second mounting plate 311 and the rotating drum 64 will decrease. If the second mounting plate 311 abuts against the rotating drum 64, the degree of wear on the auxiliary plowboard 323 will reach the maximum, and the auxiliary plowboard 323 will no longer continue to descend close to the conveyor belt. In order to prevent the auxiliary plowboard 323 from being continuously worn so that the pressing force between the auxiliary plowboard 323 and the conveyor belt is too small, thereby causing materials to be drawn between the auxiliary plowboard 323 and the conveyor belt, before pressing the auxiliary plowboard 323 against the conveyor belt, rotate the locking rod 66, rotate the limiting rod 67 out of the limiting buckle 68, pull the locking rod 66 to pull the locking rod 66 away from the limiting plate 65, and rotate the rotating drum 64 to quickly adjust the distance between the second mounting plate 311 and the first mounting plate 321, thereby changing the distance that the auxiliary plowboard 323 descends when the auxiliary plowboard 323 is worn according to the required degree of compression. When the auxiliary plowboard 323 is worn and descends, the second mounting plate 311 abuts against the rotating drum 64, effectively preventing the auxiliary plowboard 323 from being continuously worn and causing safety accidents. When the distance between the second mounting plate 311 and the first mounting plate 321 is adjusted, the locking rod 66 is inserted into the limit plate 65 to prevent the shaking of the unloading plow during use from causing the rotating drum 64 to rotate by itself, thereby facilitating locking the distance between the first mounting plate 321 and the second mounting plate 311, and continuing to push the auxiliary plowboard 323 to be pressed against the conveyor belt. At this time, the distance between the second mounting plate 311 and the rotating drum 64 serves as the maximum distance of the new auxiliary plowboard 323 due to wear.

[0039] Reference Figure 2 , Figure 4 and Figure 5, the detection device 5 includes a pressure sensor 51. The pressure sensor 51 is fixedly installed on the first mounting plate 321. A slide bar 52 is slidably installed on the second mounting plate 311. The slide bar 52 is vertically arranged directly above the pressure sensor 51. A pressure head shaft 53 is fixedly installed at one end of the slide bar 52 close to the pressure sensor 51. The pressure head shaft 53 abuts against the pressure sensor 51, and the abutting surface between the pressure head shaft 53 and the pressure sensor 51 is set as a spherical surface. A second spring 54 is sleeved on the slide bar 52. One end of the second spring 54 is fixedly connected to the pressure head shaft 53, and the other end is fixedly connected to the second mounting plate 311. A guide sleeve 55 is slidably installed on the slide bar 52. The guide sleeve 55 is arranged on the side of the second mounting plate 311 away from the first mounting plate 321. A second limit block 56 is fixedly installed at one end of the slide bar 52 away from the first mounting plate 321.

[0040] When the auxiliary plow plate 323 presses against the conveyor belt, continue to press down the second mounting plate 311. The second mounting plate 311 pushes the second spring 54 to make the pressure head shaft 53 on the slide bar 52 abut against the pressure sensor 51. By squeezing the second spring 54 through the second mounting plate 311, the thrust generated by the second spring 54 pushes the pressure head shaft 53 to press on the pressure sensor 51. Through the reading of the pressure sensor 51, the pressing degree between the auxiliary plow plate 323 and the conveyor belt can be quickly observed and judged, which is convenient for quickly adjusting the unloading plow frame 3 in place, and is beneficial to improving the convenience of the unloading plow during use.

[0041] During the use of the unloading plow, when the auxiliary plow plate 323 wears, the auxiliary plow plate 323 will slowly descend according to the degree of wear. At this time, the distance between the first mounting plate 321 and the second mounting plate 311 will increase, the elastic deformation of the second spring 54 will become smaller, and the force of the second spring 54 pushing the pressure head shaft 53 to press on the pressure sensor 51 will become smaller. Therefore, the reading of the pressure sensor 51 will become smaller. From the pressure value detected by the pressure sensor 51, it can be judged whether the unloading plow is severely worn and there is a risk of failure, thus reminding the user to maintain it in time to prevent failures.

[0042] The implementation principle of the embodiment of this application is as follows: Place the conveyor belt on the roller 21 of the guide frame 2. The roller 21 rotates following the movement of the conveyor belt, which is convenient for quickly transporting materials. Control the pushing device 4 to press the auxiliary plow plate 323 on the unloading plow frame 3 against the conveyor belt, and judge whether it reaches the accurate pressing height with the conveyor belt through the detection device 5. When the material encounters the unloading plow frame 3 and is diverted, the auxiliary plow 32 unloads the small materials on the conveyor belt, and the main plow 31 unloads the large materials above the conveyor belt, which can realize the quick unloading of materials and is beneficial to improving the convenience of the unloading plow during use.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
