It should be noted that the embodiments described here are merely used to explain and illustrate the application, and should not be used to limit the scope of the application.

[0033] The application will be described in detail with reference to the drawings, and in conjunction with exemplary embodiments.

[0034] As Figure 1 ​​​As shown, the first exemplary embodiment of the present application provides a conveying mechanism mainly comprising a conveying drum 1 and a cleaning device, wherein the cleaning device is installed in the conveying drum 1, the conveying drum 1 can be driven to rotate by a rotating motor, and a drum through hole 101 is formed through the peripheral wall of the conveying drum 1 in a radial direction. The cleaning device comprises a connector 2, a cleaning liquid pipe 3 and a spray head assembly 4, wherein the cleaning liquid pipe 3 is arranged inside the conveying drum 1 and is provided with a liquid pipe inlet and a liquid pipe outlet; the connector 2 is arranged on the conveying drum 1 and is connected to the liquid pipe inlet in a butt joint manner and is used to connect a cleaning liquid source so as to introduce the cleaning liquid into the cleaning liquid pipe 3; when the conveying drum 1 is rotating, the cleaning liquid pipe 3 and the spray head assembly 4 can be driven to rotate synchronously with the conveying drum 1 through the connector 2; and the two ends of the spray head assembly 4 are connected to the drum through hole 101 and the liquid pipe outlet in a butt joint manner respectively, so that the cleaning liquid can be sprayed out to the outer wall of the conveying drum 1 through the connector 2, the cleaning liquid pipe 3 and the spray head assembly 4 in sequence.

[0035] Therefore, the conveying mechanism of the present exemplary embodiment can spray high-pressure cleaning liquid out of the conveying drum 1 through the cleaning device when the conveying drum 1 is wrapped with weeds or adhered with dirt and other pollutants, so as to achieve the effect of weeding and decontamination, avoid the running jam of the conveying drum 1, improve the running efficiency of the conveying drum 1 and effectively prolong the service life of the conveying drum 1. During the cleaning process, the cleaning liquid pipe 3 and the spray head assembly 4 can rotate synchronously with the conveying drum 1, so as to realize multi-directional spraying of the cleaning liquid. Overall, the conveying mechanism of the present exemplary embodiment can save the trouble of manually cleaning the conveying drum 1 by adding the cleaning device in the conveying drum 1, reduce the labor intensity, and when applied to agricultural machinery such as a sugarcane harvester, the conveying mechanism can improve the harvesting efficiency without stopping the operation for cleaning.

[0036] In an alternative or preferred embodiment, as shown in Figure 2 the spray head assembly 4 comprises a movable spray head 401 which is arranged to be retractable through the drum through hole 101. Specifically, when performing the cleaning work, the movable spray head 401 can be extended out of the drum through hole 101 so as to spray the cleaning liquid outward and improve the cleaning effect; when stopping the cleaning work, the movable spray head 401 can be arranged not to extend out of the drum through hole 101, i.e. to be retracted into the conveying drum 1, so as to prevent the movable spray head 401 from being damaged when the conveying drum 1 is running, thereby protecting the movable spray head 401.

[0037] Further, as shown in Figure 1 and Figure 2As shown, the spray head assembly 4 further comprises a guide sleeve 402, two ends of the guide sleeve 402 are formed into a first sleeve open end and a second sleeve open end respectively, the first sleeve open end is connected with the liquid pipe outlet in position, the second sleeve open end is connected with the roller through hole 101 in position, and the movable spray head 401 is inserted into the guide sleeve 402. Thus, when performing the cleaning work, the movable spray head 401 can move along the axial direction of the guide sleeve 402 to partially extend out of the second sleeve open end and the roller through hole 101, when stopping performing the cleaning work, the extended movable spray head 401 can be retracted into the guide sleeve 402, under the guidance of the guide sleeve 402, the extension and retraction of the movable spray head 401 is more smooth and can be accurately extended out of the roller through hole 101.

[0038] In the above extension and retraction process, the movable spray head 401 can be driven by a linear drive device or a hydraulic drive, the present application is not limited, as long as the automatic adjustment of the movable spray head 401 can be realized, for example, the linear drive device such as linear motor is well known to those skilled in the art, thus it is not repeated here, the following specific embodiment of the hydraulic drive of the movable spray head 401 is described.

[0039] Referring to Figure 3 , two ends of the movable spray head 401 are formed into a spray head sealing end and a spray head open end respectively, the spray head open end is inserted into the guide sleeve 402, a spray hole 4011 is formed through the peripheral wall of the movable spray head 401 close to the spray head sealing end, thus, as Figure 4 shown, when the cleaning liquid pipe 3 inputs the high pressure cleaning liquid, the high pressure cleaning liquid can input the spray head sealing end and push the spray head sealing end to extend out of the roller through hole 101, until the spray hole 4011 is exposed outside the conveying roller 1, so that the cleaning liquid is sprayed outside the conveying roller 1. As can be seen, the spray head assembly 4 in the embodiment ingeniously utilizes the hydraulic pressure of the cleaning liquid pipe 3 to drive the movable spray head 401 to extend and adjust, so that the structure of the spray head assembly 4 is simple, the preparation cost is low, and at the same time, it has good spraying cleaning effect. The key is that when the spray head sealing end is retracted into the guide sleeve 402, the spray hole 4011 will not be exposed outside the conveying roller 1, which can effectively prevent the soil and dust from entering and blocking the spray hole 4011, and ensure the smooth spraying of the cleaning liquid.

[0040] Further, in order to realize the automatic retraction of the movable nozzle 401, the inner circumferential wall of the open end of the second sleeve is formed with a sleeve boss 4021 extending radially, the outer circumferential wall of the open end of the nozzle is formed with a first nozzle boss 4012 extending radially, and the nozzle assembly 4 further comprises a spring 403 sleeved outside the movable nozzle 401, one end of the spring 403 abutting against the sleeve boss 4021, and the other end of the spring 403 abutting against the first nozzle boss 4012. Thus, when the high-pressure cleaning liquid drives the movable nozzle 401 to extend, the spring 403 can be pre-tightened adaptively, and once the input of the cleaning liquid is stopped, the movable nozzle 401 can be moved back to the guide sleeve 402 under the driving of the pre-tightened spring 403, without the need for artificial control, saving time and effort.

[0041] In addition, in order to avoid the nozzle assembly 4 from falling into the cleaning liquid pipe 3, as shown in the drawings, the outer circumferential wall of the sealed end of the nozzle is formed with a second nozzle boss 4013 extending radially from the open end of the second sleeve, and the end face of the second nozzle boss 4013 abutting against the open end of the second sleeve can stop the nozzle assembly 4, preventing the nozzle assembly 4 from falling into the cleaning liquid pipe 3 along the cavity of the guide sleeve 402.
