BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 It is a schematic diagram of the overall structure of a coal feeder for preventing belt deviation according to an embodiment of the present disclosure;

[0032] Figure 2 The figure is a schematic diagram of the specific matching structure of an anti-deflection mechanism and a fixing frame according to another embodiment of the present disclosure. DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figure 1 and Figure 2 As shown, a coal feeder 100 for preventing the belt from deviating is provided, and the coal feeder 100 includes a coal feeder body 110, a transmission mechanism 120, a belt 130 and an anti-deviation mechanism 140. The transmission mechanism 120 is arranged in the coal feeder body 110, and the belt 130 is sleeved on the transmission mechanism 120 for conveying coal. The anti-deviation mechanism 140 is arranged on both sides of the width direction of the coal feeder body 110, and is used for detecting and adjusting the deviation of the belt 130. The anti-deviation mechanism 140 includes a detection component 141 and an adjustment component 142, and the detection component 141 is used to contact the belt 130 when the belt 130 deviates, and send a deviation signal to the adjustment component 142. The adjustment component 142 is used to adjust the position of the belt 130 along its width direction after receiving the deviation signal.

[0035] Specifically, Figure 1 and Figure 2As shown, the coal feeder 100 conveys coal through a belt 130 sleeved on a transmission mechanism 120. An anti-deviation mechanism 140 is provided on each of the left and right sides of the belt 130. When the belt 130 deviates during the conveying process, it will touch the detection component 141 in any of the anti-deviation mechanisms 140 on the left and right sides. At this time, the detection component 141 sends a deviation signal to the adjustment component 142. After receiving the deviation signal, the adjustment component 142 pushes the belt 130 to move in the opposite direction of the deviation until it does not touch the detection component 141.

[0036] The anti-belt deviation coal feeder of the embodiment of the present disclosure can determine whether the belt is deviated and correct the deviation after the belt is deviated. The coal feeder does not need to be shut down during the whole process, which not only ensures that the belt will not deviate, but also ensures the conveying efficiency, and can effectively improve the utilization rate and service life of the coal feeder.

[0037] Exemplarily, the transmission mechanism 120 includes a motor 121, a driving roller 122 and a driven roller 123. The driving roller 122 and the driven roller 123 are spaced along the length direction of the coal feeder body 110 and are rotatably connected to the two opposite inner side walls of the coal feeder body 110. The motor 121 is arranged on the outer side wall of the coal feeder body 110, and the output shaft of the motor 121 is drivingly connected to the driving roller 122. The belt 130 is sleeved on the outer surfaces of the driving roller 122 and the driven roller 123, and the anti-deviation mechanism 140 is respectively arranged on both sides of the belt 130 in the width direction.

[0038] Specifically, Figure 1 and Figure 2 As shown, the active roller 122 and the driven roller 123 are arranged at intervals along the length direction of the coal feeder body 110, and the belt 130 is sleeved on the active roller 122 and the driven roller 123. The output shaft of the motor 121 is connected to the active roller, so that the motor 121 drives the active roller 122 to rotate, the active roller 122 drives the belt 130, and the belt 130 drives the driven roller 123, so that the coal is transported by the belt 130. An anti-deviation mechanism 140 is respectively provided on the left and right sides of the belt 130 for deviation detection and correction of the belt 130.

[0039] It is easy to understand that the anti-deviation mechanisms 140 disposed on both sides of the width direction of the coal feeder body 110 are symmetrically arranged. That is, the two anti-deviation mechanisms 140 disposed on the left and right sides of the belt 130 are mirror-symmetrical to each other.

[0040] Furthermore, the coal feeder 100 further includes a vibration base 160 and a plurality of elastic members 170. The vibration base 160 is located at the bottom of the coal outlet end of the coal feeder body 110 and is connected to the bottom outer surface of the coal feeder body 110 through the elastic members 170.

[0041] Specifically, Figure 1 As shown, the rear end of the coal feeder body 110 is the coal inlet end, and the front end of the coal feeder 110 is the coal outlet end. The vibration base 160 is arranged at the bottom of the front end of the coal feeder body 110, and is connected to the bottom of the front end of the coal feeder body 110 through a plurality of elastic members 170. This arrangement makes the coal feeder body 100 as a whole in an inclined state, and the front end is higher than the rear end. When in use, the belt 130 is driven by the power supply of the motor 121 to continuously transport the coal from the rear end to the front end. Under the action of the vibration base 160 and the elastic member 170, the coal transported on the belt 130 can be vibrated, so that the coal is continuously transported upward and vibrated evenly, and will not accumulate in one place to affect the transportation.

[0042] For example, Figure 1 and Figure 2 The coal feeder further includes a fixed frame 150, and the detection assembly 141 includes a connecting platform 1411 and a detection wheel 1412. The fixed frame 150 passes through the hollow area enclosed by the belt 130, and the two ends of the fixed frame 150 are respectively fixed to the two opposite inner side walls of the coal feeder body 110. The connecting platform 1411 is fixed to the end side surface of the fixed frame 150, and the detection wheel 1412 is rotatably arranged on the upper surface of the connecting platform 1411 and is electrically connected to the adjustment assembly 142.

[0043] Specifically, Figure 1 and Figure 2 As shown, the connecting platform 1411 is fixed to the side surface of the corresponding end of the fixing frame 150, and the detection wheel 1412 is rotatably arranged on the upper surface of the connecting platform 1411, and the detection wheel 1412 is electrically connected to the adjustment component 142. When the belt 130 deviates during the conveying process and touches the detection wheel 1412 at either end of the fixing frame 150, the detection wheel 1412 will rotate and trigger the generation of an offset signal to be sent to the adjustment component 142. After receiving the offset signal, the adjustment component 142 adjusts the position of the belt 130 to move toward the other end of the fixing frame 150 until it does not touch the detection wheel 1412. The detection wheel 1412 can detect the offset of the belt 130.

[0044] For example, Figure 1 and Figure 2As shown, the adjustment assembly 142 includes a driving portion 1421 and a pushing portion 1422 connected to each other. The driving portion 1421 is arranged on the lower surface of the connecting platform 1411, and is used to drive the pushing portion 1422 to move toward the anti-deflection mechanism 140 at the other end. The driving portion 1421 is electrically connected to the detection wheel 1412. The pushing portion 1422 is movably mounted on the side surface of the central part of the fixing frame 150, and the upper surface of the pushing portion 1422 is connected to the belt 130.

[0045] Further, the driving part 1421 includes an oil storage tank 14211, a hydraulic pipe 14212, an oil pump 14213, a controller 14214 and a push rod 14215. The oil storage tank 14211 is arranged on the lower surface of the connecting platform 1411 and is connected to the connecting platform 1411, the connecting platform 1411 is connected to the inlet end of the oil pump 14213 through the hydraulic pipe 14212, the outlet end of the oil pump 14213 is connected to the first end of the push rod 14215, and the second end of the push rod 14215 is connected to the pushing part 1422. The controller 14214 is arranged on the oil pump 14213, and the controller 14214 is electrically connected to the oil pump 14213 and the detection wheel 1412.

[0046] Specifically, Figure 1 and Figure 2 As shown, when the belt 130 is offset and touches the detection wheel 1412 at either end of the fixed frame 150, the detection wheel 1412 rotates and sends an offset signal to the controller 14214. The controller 14214 sends a command to the oil pump 14213. The oil pump 14213 works to continuously push the push rod 14215. The push rod 14215 drives the pushing part 1422 to continuously push and push the belt 130 to a position where it will not touch the detection wheel 1412, thereby correcting the offset belt 130.

[0047] It should be noted that the configuration of the pusher is such that when the belt moves along the length direction of the coal feeder body, there is no friction between the belt and the pusher. When the pusher pushes the belt along the width direction of the coal feeder body, the friction between the two parts increases to complete the pushing. As a specific example, Figure 2 As shown, the installation height of the push part 1422 is higher than the fixing frame 150, and the push part 1422 includes at least one M-shaped structure, and the upper surface of the push part 1422 contacts the inner side of the belt 130. The coal feeder body 110 can be set to stainless steel, and the detection wheel 1412 and the oil storage tank 14211 are both set to cylindrical, and the diameters of the two correspond.

[0048] For example, Figure 2As shown, the driving part 1421 also includes an airbag 14216, and the airbag 14216 is penetrated by the push rod 14215. Further, the push rod 14215 includes a first sub-push rod (not marked in the figure) and a second sub-push rod (not marked in the figure). The first end of the first sub-push rod is connected to the outlet end of the oil pump 14213, and the second end thereof is connected to one end of the second sub-push rod, and the other end of the second sub-push rod is connected to the pushing part 1422. The first sub-push rod is perpendicular to the second sub-push rod, and the first sub-push rod is penetrated by the airbag 14216.

[0049] Specifically, Figure 2 As shown, the push rod 14215 includes a first push rod and a second push rod, and the first push rod and the second push rod are in an L-shaped structure. In addition, the first push rod is also provided with an air bag 14216, and the second push rod is connected to a push portion 1422.

[0050] The coal feeder for preventing belt deviation in the embodiment of the present disclosure can detect deviation by setting detection wheels on both sides of the belt. The belt can be corrected by the pushing of the pushing part to ensure that the belt does not deviate and the conveying efficiency is guaranteed. The whole working process does not need to be stopped, which effectively improves the utilization rate and service life of the coal feeder.

[0051] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present disclosure, but the present disclosure is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and substance of the present disclosure, and these modifications and improvements are also considered to be within the scope of protection of the present disclosure.
