Problems solved by technology

If the crops to be harvested are relatively dry, they are easy to thresh during harvesting and the threshing loss rate is high. However, when the crops to be harvested are relatively wet and enter the threshing device, it is not easy to thresh or the threshing is incomplete, which will also increase the loss rate of grains; In actual production, due to the influence of various factors during harvesting, the crops are neither too dry nor wet during harvesting. Therefore, a harvester threshing device is developed to improve the threshing efficiency when the crops are relatively dry. Threshing is more complete when it is more humid, so as to solve the problem of high threshing loss rate without increasing the load of the threshing device and affecting the service life of the device, which has great social significance and economic benefits for the country and farmers
[0003] But present harvester threshing device mostly has poor threshing effect, especially when the described crops to be threshed are not dry enough, threshing rate is low; Some harvester threshing devices in the prior art are in order to strengthen threshing efficiency, and throughput (The stalk entering the threshing device is required to be no higher than 30cm), and the load on the machine is increased, which shortens the life of the harvester

Abstract

A threshing device of a harvester comprises a main shaft, a bearing seat, a toothed nail, a reinforcing ring, a toothed nail fixing angle steel, an input port, an output port and an upper cover. The threshing device is characterized in that a threshing round disc is arranged on the main shaft by taking the main shaft as the center of the round disc; the threshing round disc is fixedly connected with the toothed nail fixing angle steel; and the threshing round disc has a distance of 440mm from the right end of the input port, and a distance of 80 to 110mm from the right end of the output port. The threshing device of the harvester is safe and reliable, and has the advantages of high stability and high threshing speed. In addition, the threshing device has the following advantages: the threshing device has high threshing efficiency and can handle about 1Mu wetter crops in one hour; the threshing device can handle crops with the length of 40cm, and has high throughput, which is higher than that of the prior at by more than 30%; and the threshing device has low threshing loss rate (smaller than 1.18%), which is superior to the national standard (1.2%).

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a small harvester threshing device. Background technique [0002] Harvesters are harvesting crops with stalks, such as wheat or rice, which need to be threshed. If the crops to be harvested are relatively dry, they are easy to thresh during harvesting and the threshing loss rate is high. However, when the crops to be harvested are relatively wet and enter the threshing device, it is not easy to thresh or the threshing is incomplete, which will also increase the loss rate of grains; In actual production, due to the influence of various factors during harvesting, the crops are neither too dry nor wet during harvesting. Therefore, a harvester threshing device is developed to improve the threshing efficiency when the crops are relatively dry. The threshing is more complete when it is more humid, so as to solve the problem of high threshing loss rate without increasing the load of the thres...
