Abstract

The invention relates to the field of agricultural harvesting machinery, and particularly discloses a threshing device which comprises a left wall plate, a right wall plate and cleaning facilities, wherein the left wall plate and the right wall plate are fixed on the main body of a harvesting machine or a reaping machine; the cleaning facilities are arranged on the left wall plate and the right wall plate; a drum shaft is arranged between the left wall plate and the right wall plate, and sleeved by a spike-tooth drum; a concave plate screen is arranged below the spike-tooth drum; screen holes are formed in the concave plate screen; the concave plate screen is connected between the left wall plate and the right wall plate, and totally covers the spike-tooth drum; the spike-tooth drum is sleeved by a housing; the housing is a hollow cylinder with openings formed in the side surface; radial bulges and leaks are formed on and in both the inner wall and the outer wall on the side surface of the housing; the housing is connected onto the drum shaft, and can rotate around the drum shaft together with the spike-tooth drum.

Description

technical field [0001] The invention relates to the field of agricultural harvesting machinery, and specifically discloses a threshing device. Background technique [0002] In an agricultural harvester or harvester, a threshing device is an essential structure. The threshing device is mainly used to separate sundries such as grain stalks from the grain. [0003] Existing threshing devices generally include a drum shaft, a spiked drum rotating around the rolling shaft, and a concave plate screen arranged below the spiked drum. During threshing, it mainly relies on the impact of the spikes on the spiked drum on the grain and the grinding effect of the spiked teeth on the spiked drum and the concave plate sieve on the grain to make the grain fall off and leak out from the holes on the concave plate sieve. [0004] However, because the feeding amount is too large, the grinding movement between the spiked drum and the concave plate sieve is difficult, and the relative movement ...
