Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural machinery and equipment, and particularly relates to a material conveying device for a pepper harvesting machine. BACKGROUND

[0002] The existing pepper harvesting machines on the market can be roughly divided into two categories: one type does not have a cleaning system or only has one cleaning fan, and the material conveying of the whole machine is conveyed to the elevator through the bridge, and then directly thrown into the grain collecting box, which is simple in mode and simple in structure layout; the other type has a cleaning system, and the material is thrown to the cleaning system through the bridge, and the material is separated and conveyed to the rear of the whole machine by the cleaning system, and the waste is thrown out of the machine, and the cleaned material is conveyed to the conveying belt above through the vertical elevator, and then thrown into the granary; this scheme is complex in structure, large in size of the whole machine, not suitable for operation in the central region, and difficult to popularize and apply. The existing harvester has the following shortcomings: 1. The existing material conveying structure is one-section type transmission, which is prone to spilling due to insufficient power during transmission, resulting in waste of peppers; 2. During the process of pepper harvesting, a material collecting vehicle is beside to collect material, and when one material collecting vehicle is full, another material collecting vehicle is replaced, which is prone to pepper scattering; 3. During the process of pepper harvesting, there are a large amount of straw and other impurities in it, and the existing harvester cannot realize on-site impurity removal, which is prone to subsequent complicated process.

[0003] In the Chinese utility model patent with the application number 201920500477.4, a pepper harvesting machine is disclosed, which comprises a harvesting box, a collecting bin is arranged on the side of the harvesting box away from the harvesting end, the bottom of the harvesting box is communicated with the collecting bin through a first connecting cylinder, the end of the collecting bin away from the harvesting box is fixedly connected with a cleaning bin through a conveying pipe, a fan is arranged on the conveying pipe, the end of the cleaning bin away from the conveying pipe is fixedly connected with a storage bin through a second connecting cylinder, and a cab is arranged on the side of the cleaning bin away from the storage bin. The patent cooperates with the harvesting box, the collecting bin and the conveying pipe under the control of the cab, drives the harvesting box to harvest peppers through the driving device, and then cooperates with the collecting bin and the conveying pipe to convey the peppers into the storage bin for collection. However, the pepper harvesting machine of the patent cannot separate the stems and leaves of the peppers from the peppers during the harvesting and storage process, so the stems and leaves of the peppers need to be removed in the subsequent process, which increases the work intensity, causes the subsequent process to be complicated, and reduces the work efficiency.
