Description

Technical Field

[0001] The utility model relates to the technical field of broad bean threshing equipment, in particular to a broad bean harvesting and threshing device. Background Art

[0002] The threshing devices on the market mainly include a threshing filter and a threshing drum that rotates in conjunction with the threshing device. When threshing broad beans, after the broad bean horns are removed from the vines, they need to be beaten to knock the dry broad bean shells into pieces and leave the broad beans in the threshing filter.

[0003] The existing publication number is CN204888041U, and the name is a broad bean threshing device, which includes a threshing filter and a threshing drum arranged on the inner side of the threshing filter, a threshing chamber is formed between the threshing filter and the threshing drum, and the threshing drum includes a drum body, a threshing mechanism is arranged on the side of the drum body, and a power connecting piece is arranged on one end face of the drum body. When in use, the broad bean crop enters the threshing chamber from the feeding port on one side of the threshing drum, and as the threshing drum rotates, the threshing teeth on the threshing drum continuously impact and stir the broad bean crop to separate the broad beans from the stems; and the separated broad beans are discharged from the filter holes of the threshing filter, and the stems continue to rotate with the threshing drum and are discharged from the discharge port on the other side of the threshing drum, thus completing the threshing of the broad bean crop. Furthermore, since the distance between the end of the threshing teeth and the threshing filter is higher than the height of the broad beans, the broad beans will not be stuck between the end of the threshing teeth and the threshing filter, thus avoiding the jamming situation; at the same time, the space of the threshing cavity is effectively increased, so that the broad bean crops can be more evenly impacted and stirred by the threshing teeth in the threshing cavity, and threshing can be carried out smoothly, thereby improving the threshing rate and threshing efficiency.

[0004] However, in the above-mentioned equipment for threshing broad beans, the dry broad bean corners are squeezed by the threshing teeth, so that the broad bean corners are opened to squeeze out the broad beans, and the broad beans are dropped through the threshing net tube for collection. However, this behavior of using threshing teeth to squeeze and thresh, because multiple threshing teeth are arranged horizontally and the intervals between the multiple threshing teeth are large, it is impossible to fully squeeze the broad beans in the threshing net tube, which affects the adequacy of threshing of the broad beans.
