[0001] The utility model relates to the technical field of bucket elevators, in particular to a conveying chain drive assembly of a bucket elevator. Background Technique

[0002] A bucket elevator is driven by a motor to rotate a sprocket. Under the action of the rotation of the sprocket, a plurality of buckets on the chain are driven to operate, so as to realize the vertical conveying of materials. During the process of using the sprocket to drive the chain transmission, in order to prevent the chain from becoming loose due to temperature differences or stretching during long-term operation, which affects the transmission efficiency and accuracy, a tensioning device is used to adjust the tension of the chain. However, when the bucket elevator is not working and the chain does not need to rotate, under the action of the tensioning device, the chain still remains continuously tight, which easily increases the risk of chain breakage and thus reduces the service life of the chain.

[0003] Therefore, there is an urgent need for a conveying chain drive assembly of a bucket elevator to solve the above problems. Summary of the Utility Model

Detailed implementation manner

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] Please refer to Figures 1-5 , a conveying chain drive assembly of a bucket elevator shown in the figure, including a housing 101 and a conveyor chain 102 arranged inside the housing 101. A plurality of buckets 103 are arranged on the side wall of the conveyor chain 102. A first sprocket for rotating the conveyor chain 102 is arranged near the feed port of the housing 101. The drive assembly for driving the conveyor chain 102 is also included and arranged in the housing 101;

[0023] The drive assembly includes a drive pipe 201 rotatably connected to one side of the housing 101 near the discharge port. A plurality of sliding plates 202 are slidably connected to the side wall of the drive pipe 201 in a circular array. One end of each sliding plate 202 away from each other is fixedly connected with a sprocket tooth 203. Each sprocket tooth 203 is engaged with the conveyor chain 102. A drive motor 204 is arranged on the outer side wall of the housing 101. The output end of the drive motor 204 is connected to the drive pipe 201. The drive pipe 201 is provided with an adjustment assembly for adjusting the distance between each sprocket tooth 203;

[0024] It should be noted here that: through the setting of the drive assembly, under the combined action of the adjustment assembly and the drive assembly, during the process of driving the conveyor chain 102, it is convenient to timely adjust the tension of the conveyor chain 102, thereby ensuring the timeliness and accuracy of adjusting the tension of the conveyor chain 102. At the same time, after the conveyor chain 102 finishes driving, the tension of the conveyor chain 102 is reduced, so that the conveyor chain 102 remains in a relaxed state when not working, thereby avoiding the risk of increasing the breakage of the conveyor chain 102 due to long-term tension, and thus ensuring the normal service life of the conveyor chain 102.

[0025] It should be noted that as an existing technology, the specific structure and working principle of the bucket elevator are already known to those skilled in the art, and will not be elaborated here.

[0026] Please refer to Figure 3 and Figure 4 , in the figure, the adjustment assembly includes a U-shaped frame 301 fixedly connected to the inner wall of the transmission pipe 201. The U-shaped frame 301 is connected with an adjustment rod 302 through a guiding assembly. A tapered column 303 is slidably connected in the transmission pipe 201. One end of the adjustment rod 302 away from the sprocket tooth 203 is abutted against the side wall of the tapered column 303. The transmission pipe 201 is provided with a driving assembly for driving the tapered column 303.

[0027] It should be noted here that through the setting of the adjustment assembly, it is convenient to push the sprocket teeth 203 away from each other, so as to adjust the tension of the conveyor chain 102.

[0028] Please refer to Figure 3 and Figure 4 , one end of each adjustment rod 302 away from the tapered column 303 in the figure is provided with a pressure sensor 304, and one end of the sliding plate 202 is connected to the detection end of the pressure sensor 304.

[0029] It should be noted here that through the setting of the pressure sensor 304, it is convenient to detect the transmission gap of the conveyor chain 102 in time, and use the adjustment assembly to adjust the transmission gap of the conveyor chain 102 in time and accurately. Thus, while ensuring the convenience of adjusting the tension of the conveyor chain 102, the timeliness and accuracy of adjusting the tension of the conveyor chain 102 are improved.

[0030] It should be noted that the detection of the pressing pressure of the pressure sensor 304 on the conveyor chain 102 is mainly the maximum pressure value during one-week rotation. Since the sprocket teeth 203 are constantly rotating, only when the sprocket teeth 203 are at the highest position, the pressure is the largest. Therefore, by detecting the maximum pressure of the sprocket teeth 203 to judge the tightness of the conveyor chain 102, the model of the pressure sensor 304 is D1210.

[0031] Please refer to Figure 3 and Figure 4 , in the figure, the guiding assembly includes a guiding groove 501 opened on the side wall of the adjustment rod 302. A guiding strip 502 is slidably connected in the guiding groove 501. One side of the guiding strip 502 is connected to the U-shaped frame 301.

[0032] It should be noted here that through the setting of the guiding assembly, it is used to provide guiding and limiting functions for the movement of the adjustment rod 302.

[0033] Please refer to Figure 3 and Figure 4, a reset component for resetting the sprocket teeth 203 is provided on the side wall of each adjusting rod 302 in the illustration. The reset component includes a fixing ring 601 fixedly connected to the side wall of the adjusting rod 302. A spring 602 is sleeved on the side wall of the adjusting rod 302, and both ends of the spring 602 are connected to the fixing ring 601 and the U-shaped frame 301 respectively;

[0034] It should be noted here that: through the setting of the reset component, it is used to drive the sprocket teeth 203 to move closer to each other.

[0035] Working principle: When this bucket elevator is in use, start the drive motor 204 to drive the drive pipe 201 to rotate. During the rotation of the drive pipe 201, it will drive each sprocket tooth 203 to rotate. Then, due to the driving effect of each sprocket tooth 203 on the conveyor chain 102 and the supporting and driving effect of the first sprocket on the conveyor chain 102, the conveyor chain 102 will be driven, and further drive each bucket 103 on the conveyor chain 102 to move, thus realizing the vertical conveying of materials;

[0036] During the process of the conveyor chain 102 driving the buckets 103, due to temperature differences or stretching during long-term operation, the conveyor chain 102 may become loose. When the conveyor chain 102 becomes loose, during the driving process, the extrusion on the sprocket teeth 203 will be reduced, and then the sliding plate 202 will reduce the extrusion on the pressure sensor 304. When the tightening pressure is less than the set threshold value, the driving component will be used to drive the tapered column 303 to move. Then, during the movement of the tapered column 303, under the interaction force between the tapered column 303 and the adjusting rod 302 and the guiding effect of the guiding component, each adjusting rod 302 will be pushed to move away from each other, and further push each sprocket tooth 203 to move away from each other, so that each sprocket tooth 203 remains in tight contact with the loose conveyor chain 102, trimming the driving gap of the conveyor chain 102, further realizing the tensioning of the conveyor chain 102. And under the detection of the pressure sensor 304, it is convenient to detect the driving gap of the conveyor chain 102 in time, and use the adjusting component to adjust the driving gap of the conveyor chain 102 timely and accurately. Thus, while ensuring the convenience of adjusting the tension of the conveyor chain 102, the timeliness and accuracy of adjusting the tension of the conveyor chain 102 are improved, avoiding the decline of the driving performance of the conveyor chain 102 or the breakage of the conveyor chain 102 caused by over-loose or over-tight adjustment of the conveyor chain 102, and further ensuring the stability of material lifting;

[0037] When the bucket elevator finishes lifting the material, under the combined action of the adjusting component and the reset component, the sprocket teeth 203 approach each other, thereby reducing the tension on the conveyor chain 102. When the conveyor chain 102 is not working, it remains in a relaxed state, avoiding the risk of breakage of the conveyor chain 102 due to long-term tension, and thus ensuring the normal service life of the conveyor chain 102.

[0039] Please refer to Figure 5 , this embodiment further illustrates Embodiment 1. The drive assembly in the figure includes a drive frame 701 fixedly connected to the bottom wall on one side of the drive tube 201. The drive frame 701 is slidably connected with a drive plate 702. One end of the drive plate 702 is connected to the conical column 303. The other bottom wall of the drive tube 201 is fixedly connected with a push rod motor 704. The output end of the push rod motor 704 is connected to the conical column 303;

[0040] It should be noted here that: through the setting of the drive assembly, under the driving force of the push rod motor 704 and the guiding action of the drive frame 701 and the drive plate 702, the conical column 303 is driven to slide in the drive tube 201.
