Specific embodiment
Below by specific embodiment combination attached drawing, the present invention is described in detail.
Referring to Fig. 1, bidirectional reciprocating threshing cylinder according to the present invention mainly includes the first threshing cylinder assembly 1, second
Threshing cylinder assembly 2 and drum connecting passage 3.First threshing cylinder assembly 1 is arranged side by side with the second threshing cylinder assembly 2, but
The impurity discharging port of first threshing cylinder assembly 1 is opposite with the feed inlet of the second threshing cylinder assembly 2, the first threshing cylinder assembly 1
The impurity discharging port of feed inlet and the second threshing cylinder assembly 2 is located at the same side；Drum connecting passage 3 connects the first threshing cylinder assembly
The feed inlet of 1 impurity discharging port and the second threshing cylinder assembly 2 forms U-shaped material conveying passage.In order to facilitate conveying, first
The discharge port of threshing cylinder assembly 1 is higher than the feed inlet of the first threshing cylinder assembly 2.
Referring specifically to Fig. 2-3, the first threshing cylinder assembly 1 include feeding head 4, level-one roller shell 13, level-one roller 6,
Level-one separates notch board 5, and feeding head 4 is connect with level-one roller shell 13, and 6 front end of level-one roller is provided with level-one roller and imports cone 7,
Level-one separates notch board 5 and is arranged below level-one roller 6.4 front of feeding head is connected with gap bridge, and fruit ear is led by level-one roller here
Enter cone 7 and import rear, threshing is carried out by level-one roller 6.The general flare of head 4 is fed, inner wall surface is provided with spiral shape
Deflector cooperates together with level-one roller importing cone 7 and conveys fruit ear backward.The threshing element that level-one roller 6 uses is rasp bar block
11.Rasp bar block 11 is the block elements that surface has burr, carries out rubbing threshing to corn ear, this threshing element is not fragile
Broken corn kernel, the grain harvest being particularly suitable under high-moisture percentage.Level-one separates notch board 5 all using more round bar spacing side by side
It forms, gap is larger, it is ensured that seed is fallen, and the biggish fruit ear not purified and fruit ear mandrel stay in roller.
Referring specifically to Fig. 3-4, the second threshing cylinder assembly 2 includes two stage cylinder shell 14, two stage cylinder 9, the second-order separation
Notch board 10,9 front end of two stage cylinder are provided with two stage cylinder and import cone 8, and the second-order separation notch board 10 is arranged below two stage cylinder 9.
The threshing element that two stage cylinder 9 uses carries out impact threshing to corn ear and separates for spike-tooth 12.The second-order separation notch board 10 is main
It to be lattice-shaped, gap is smaller, it is ensured that seed is fallen, and fruit ear mandrel and other sundries stay in roller.Under preferable case,
By flow direction of material, preceding the 1/4 of the second-order separation notch board 10 is formed using more round bar spacing side by side, behind 3/4 use lattice-shaped, such as
Shown in Fig. 4.
Level-one roller in the present invention imports cone 7 and two stage cylinder imports cone 8 and all imports cone using spiral, outside level-one roller
Spiral deflector is both provided on the inner wall of shell 13 and two stage cylinder shell 14, so that material be facilitated to convey backward.
Bidirectional reciprocating threshing cylinder specific work process of the invention are as follows: feeding head 4 connection pass a bridge, by corn ear from
Gap bridge delivers into the first threshing cylinder assembly 1, and level-one roller 6 carries out rubbing threshing to corn ear, and seed is separated from level-one
Notch board 5 falls on seed collecting bin, and the biggish fruit ear not purified and fruit ear mandrel are defeated by drum connecting passage 3 in roller
It is fed into the second threshing cylinder assembly 2, two stage cylinder 9 carries out impact threshing to corn ear and separates, and seed is from the second-order separation
Notch board 10 falls into seed collecting bin, and fruit ear mandrel and other sundries stay in roller, is finally discharged from two stage cylinder impurity discharging port 15.
To reduce peasant burden, increases peasant income, improve China's corn harvest mechanization level, the present invention devises one
Kind of bidirectional reciprocating threshing cylinder, the roller can smoothly realize the requirement that corn kernel is directly received, during solving grain harvest
Crushing Problem, while reducing the longitudinal size of entire roller, be widely used in corn kernel and directly receive, especially the North China Plain
Harvest requirement.
It should be appreciated by those skilled in the art that specific embodiment described above is only for more fully understanding the present invention, and
It is not used in and limits the invention, protection scope of the present invention should be subject to the restriction of claims.
