Embodiment 1

[0044] The variable-direction threshing corn thresher includes a feed inlet 4, a threshing drum 7, a silo shell 5, a corn kernel discharging port and a corn cob discharging port 6, and the threshing drum 7 is arranged obliquely.

[0045] Such as figure 1 As shown, the barrel 7 is cylindrical, and the barrel wall surface of the barrel 7 is provided with only one layer of spiral barrel ribs. The spiral barrel includes an upper barrel 1 and a lower barrel 2 with opposite spiral directions. The upper barrel is threshed. The spiral direction of the rib 1 is opposite to the rotation direction of the barrel 7, and the spiral direction of the lower barrel 2 is the same as the rotation direction of the barrel 7; the corncob outlet 6 is set in the upper barrel 1 and the lower barrel 2 to connect At the corresponding side. The change of the spiral direction of the threshing bar changes the direction of movement of the corn cobs in the threshing bin. After being cleaned, the corn cobs are di...

Embodiment 2

[0054] The variable-direction threshing corn thresher includes a feed port 4, a threshing barrel 7, a silo shell 5, a corn kernel discharging port and a corn cob discharging port 6, and the threshing drum 7 is arranged obliquely.

[0055] The threshing barrel 7 is cylindrical, and the barrel wall surface of the barrel 7 is provided with an inner threshing bar 3 and an outer threshing bar. The outer threshing bar includes an upper threshing bar 1 and a lower threshing bar 2, an upper threshing bar 1 and a lower threshing bar. Ribs 2 are all spiral threshing ribs. The spiral direction of upper threshing rib 1 and lower threshing rib 2 are opposite, the spiral direction of upper threshing rib 1 is opposite to that of barrel 7, and the spiral direction of lower threshing rib 2 is the same as that of barrel 7. The rotation direction is the same; the inner threshing bar 3 is a ring-shaped threshing bar, and the density of the inner threshing bar 3 is significantly greater than the densi...

Embodiment 3

[0073] The variable-direction threshing corn thresher includes a feed port 4, a threshing barrel 7, a silo shell 5, a corn kernel discharging port and a corn cob discharging port 6, and the threshing drum 7 is arranged obliquely.

[0074] The threshing barrel 7 is cylindrical or truncated.

[0075] When only one layer of threshing bars is provided, the arrangement of the threshing bars is consistent with the structure in Example 1.

[0076] When two layers of threshing bars are provided, the arrangement of the threshing bars is consistent with the structure in Example 2.

Abstract

The invention discloses a corn thresher capable of carrying out deflecting threshing. The corn thresher comprises a feeding port, a threshing barrel, a bin shell, a corn kernel discharge port and a corncob discharge port, the threshing barrel is obliquely arranged, at least one layer of threshing ribs is arranged on the threshing barrel, each threshing rib comprises an upper threshing rib segment and a lower threshing rib segment, the upper threshing rib segments and the lower threshing rib segments are all spiral threshing ribs and are opposite in spiral direction, the spiral direction of the upper threshing rib is opposite to the rotating direction of the threshing barrel, and the spiral direction of the lower threshing rib segments is identical to the rotating direction of the threshing barrel. The corncob discharge port is formed in the side face corresponding to the connecting positions of the upper threshing rib segments and the lower threshing rib segments. The motion track of corn cobs entering a threshing bin is limited by arranging the deflecting ribs, the height of the threshing bin is changed by changing the barrel diameter of the threshing barrel or the double-layer ribs, and therefore the corn cobs can be fully threshed in different spaces of the threshing bin, the threshing performance can be greatly improved, and the non-threshing work sections of the threshing bin are reduced.

Description

technical field [0001] The invention relates to the field of corn threshers, in particular to a corn thresher with variable orientation. Background technique [0002] In the field of traditional small corn threshers, there are two types of corn threshers, one is a thresher that feeds corn cobs horizontally, and the other is a thresher that feeds corn cobs vertically. [0003] According to the time when these two types of threshing machines came out, the horizontal feeding threshing machine came out first, but for this type of threshing machine, the corn cob enters the threshing bin, and then rolls along the wall of the threshing cylinder for threshing, and the threshing track is short. , and the removal rate is low. [0004] Therefore, along with the needs of the society, a vertical feed corn thresher with better threshing effect has appeared. This type of vertically fed corn thresher, for example, the publication number is CN201563399U, and the publication date is the Ch...
