All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0022] Embodiment 1

[0023] Please refer to Figures 1 - 5 , a hoist conveyor chain drive assembly shown in the figure, including a housing 101. A first sprocket 102 and a second sprocket 103 are arranged in the housing 101. A conveyor chain 104 is closed and wound between the first sprocket 102 and the second sprocket 103. A plurality of buckets 105 are equidistantly arranged on the side wall of the conveyor chain 104. The housing 101 is provided with a drive motor 106 for driving the conveyor chain 104 through a fixed bracket, and further includes a connection assembly arranged on the drive motor 106 for connecting with the first sprocket 102;

[0024] The connection assembly includes a connecting pipe 201 fixedly connected to the output end of the drive motor 106. A plurality of connecting holes 202 are opened on the side wall of the connecting pipe 201. Two rotating shafts 203 are rotatably connected to the housing 101. One ends of the two rotating shafts 203 facing each other are connected to the first sprocket 102. One of the two rotating shafts 203 close to the drive motor 106 is connected with a circular plate 204 through a power transmission assembly. The circular plate 204 is connected with a connecting plate 205 through a plurality of telescopic assemblies. Each connecting plate 205 is arranged to match the connecting holes 202. The connecting pipe 201 is provided with a pushing assembly for pushing each connecting plate 205;

[0025] It should be noted here that: through the setting of the connecting component, under the combined action of the power transmission component and the pushing component, during the connection and disassembly process of the first sprocket 102 and the driving motor 106, only by pushing the transmission rod 403 and rotating the threaded ring 601, the quick connection and disassembly of the first sprocket 102 and the driving motor 106 can be achieved. Thus, while ensuring the connection stability between the driving motor 106 and the first sprocket 102, the connection and disassembly convenience between the driving motor 106 and the first sprocket 102 is improved, and further the maintenance and repair efficiency of the conveying chain 104 or the driving motor 106 in the subsequent process is improved.

[0026] It should be noted that: as a prior art, the specific structure and working principle of the bucket elevator have been mastered by those skilled in the art, and will not be elaborated here.

[0027] Please refer to Figure 4 and Figure 5 , on one side of each connecting plate 205 close to the driving motor 106 in the figure, an inclined surface 206 is provided;

[0028] It should be noted here that: through the setting of the inclined surface 206, when each connecting plate 205 on the circular plate 204 abuts against the end face of the connecting pipe 201, under the mutual acting force of the inclined surface 206 and the guiding action of the telescopic component, each connecting plate 205 will be pushed to contract into the telescopic cavity 301.

[0029] Please refer to Figure 4 and Figure 5 , the telescopic component in the figure includes a telescopic cavity 301 opened on the circular plate 204. A telescopic plate 302 is slidably connected to the telescopic cavity 301. One end of the connecting plate 205 is connected to the telescopic plate 302. A first spring 303 is fixedly connected to the bottom wall of the telescopic cavity 301, and the other end of the first spring 303 is connected to the telescopic plate 302;

[0030] It should be noted here that: through the setting of the telescopic component, it provides guiding and resetting functions for the movement of the connecting plate 205.

[0031] Please refer to Figure 4 and Figure 5 , the power transmission component in the figure includes a spline hole 401 opened on the rotating shaft 203. A spline plate 402 is slidably connected to the spline hole 401. A transmission rod 403 is fixedly connected to one side of the spline plate 402 close to the circular plate 204. The end of the transmission rod 403 away from the spline plate 402 is connected to the circular plate 204;

[0032] It should be noted here that: through the setting of the power transmission component, it is convenient to transmit the driving force of the driving motor 106 to the first sprocket 102.

[0033] It should be noted that when the first sprocket 102 is connected to the drive motor 106, one side of the spline plate 402 will abut against the inner wall of the spline hole 401.

[0034] Please refer to Figure 4 and Figure 5 As shown in the figure, a second spring 5 is fixedly connected to the bottom wall of the spline hole 401, and the other end of the second spring 5 is connected to the spline plate 402;

[0035] It should be noted here that through the setting of the second spring 5, during the process of releasing the connection limit between each connecting plate 205 and the connecting hole 202, a pulling effect is exerted on the circular plate 204.

[0036] Working principle: When using the elevator to lift materials, first pull the transmission rod 403, so that the circular plate 204 at one end of the transmission rod 403 is inserted into the connecting pipe 201. When the circular plate 204 is inserted into the connecting pipe 201, when each connecting plate 205 on the circular plate 204 abuts against the end face of the connecting pipe 201, under the mutual acting force of the inclined surface 206 and the guiding action of the telescopic assembly, each connecting plate 205 will be pushed to contract into the telescopic cavity 301;

[0037] With the continuous pushing of the transmission rod 403, when each connecting plate 205 coincides with the connecting hole 202, under the elastic action of the telescopic assembly, each connecting plate 205 will be pushed to move away from each other and inserted into the connecting hole 202, so that under the connection action of each connecting plate 205, the connection limit between the circular plate 204 and the connecting pipe 201 is realized;

[0038] After the connection limit between the circular plate 204 and the connecting pipe 201 is achieved, start the drive motor 106 to drive the connecting pipe 201 to rotate. Under the connection limit action between the circular plate 204 and the connecting pipe 201, drive the transmission rod 403 to rotate, and then drive the first sprocket 102 to rotate through the power transmission assembly, so that under the rotation action of the first sprocket 102 and the supporting action of the second sprocket 103, each bucket 105 on the conveying chain 104 rotates, thus realizing the vertical conveying of materials;

[0039] When maintenance and repair of the drive motor 106 or the conveying chain 104 are required, use the pushing assembly to release the connection limit between each connecting plate 205 and the connecting hole 202, and then the connection between the first sprocket 102 and the drive motor 106 is released. Thus, while ensuring the connection stability between the drive motor 106 and the first sprocket 102, the connection and disassembly convenience between the drive motor 106 and the first sprocket 102 are improved, and further the maintenance and repair efficiency of the subsequent conveying chain 104 or drive motor 106 is improved.

[0040] Embodiment 2

[0041] Please refer to Figure 5 , in this embodiment, a further description is made for Embodiment 1. The pushing assembly in the figure includes a threaded ring 601 threadedly connected to the side wall of the connecting pipe 201. A pushing ring 602 is fixedly connected to the side of the threaded ring 601 away from the driving motor 106. Chamfers 603 are formed on the sides of the respective connecting plates 205 away from the driving motor 106;

[0042] It should be noted here that: through the setting of the pushing assembly, during the rotation of the threaded ring 601, by utilizing the threaded meshing transmission effect, the pushing ring 602 is driven to move closer to the respective connecting plates 205. When the pushing ring 602 abuts against the respective connecting plates 205, under the mutual acting force of the inclined surfaces 206, the respective connecting plates 205 will be pushed to contract into the connecting pipe 201. After the respective connecting plates 205 contract into the connecting pipe 201, the transmission rod 403 can be pulled. Thus, under the pulling force and the elastic force of the second spring 5, and under the interaction between the chamfers 603 on the respective connecting plates 205 and the connecting pipe 201, the circular plate 204 will be driven to move out of the connecting pipe 201, thereby releasing the limit between the circular plate 204 and the connecting pipe 201, and further releasing the connection between the first sprocket 102 and the driving motor 106.

[0043] It is worth noting that: the inclination of the chamfer 603 of the connecting plate 205 is consistent with the thickness of the inner wall of the connecting pipe 201. Thus, when the connecting plate 205 is flush with the outer side wall of the connecting pipe 201, under the mutual acting force of the chamfer 603, the connecting plate 205 will be further pushed to contract into the telescopic cavity 301. When the connecting plate 205 is used for connection, the chamfer 603 will not contact the side wall of the connection hole 202, so that the side wall of the connecting plate 205 abuts against the inner wall of the connection hole 202 for connecting and limiting the connecting pipe 201.

[0044] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
