Cotton harvesting impurity elimination experimental bench provided by the invention, each unit of clearing up can be controlled separately, and be respectively completed independent test Transaction capabilities or the test of whole synthesis transaction capabilities;Each clearing function transition freely, does not increase again by wind-force transhipment unginned cotton Raw impurity, while cotton fiber is damaged few.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings.
Fig. 1 is the structural schematic diagram of a preferred embodiment of the invention.
Specific embodiment
Embodiment
The cotton harvesting impurity elimination experimental bench of the present embodiment, such as Fig. 1, comprising: feeding hopper 3, expansion chamber 1, shaft cleaning bar unit 2, Clear bell unit 7, dust cage 16 and the thin miscellaneous cleaning unit 13 of multi-cascade group;3 open-top of feeding hopper, bottom are connected to by first pipe Expansion chamber 1,3 bottom of feeding hopper are also connected with the first blower 6 dried towards first pipe;The bottom of feeding hopper 3 is equipped with first Air-valve 5 is closed, first top for closing air-valve 5 is equipped with feeding roller 4 in feeding hopper 3, and the top of the unginned cotton picked from feeding hopper 3 is direct It is put into or falls into feeding hopper 3, then in the case where gravity and feeding roller 4 act on, air-valve 5 is closed in entrance first, and first closes air-valve 5 can be with Effectively the wind effect of the first blower 6 is avoided to feed, then unginned cotton enters expansion chamber 1 from first pipe under wind blows, sedimentation Room 1 has mesh enclosure shell, and the broken leaf of dust and part passes through the discharge of 1 mesh enclosure shell of expansion chamber (or entering cleaner) with the wind.
1 bottom of expansion chamber is connected to shaft cleaning bar unit 2;Shaft cleaning bar unit 2 includes several caltrop rollers, and caltrop roller is to tilt upward Direction arranged;Shaft cleaning bar unit 2 has unginned cotton outlet and the outlet of branch bar, and unginned cotton outlet is located at the caltrop roller of extreme higher position Side, the outlet of branch bar are located at below caltrop roller, have glazing bar grid between the outlet of branch bar and caltrop roller.Enter shaft cleaning bar from expansion chamber 1 2 unginned cotton of unit carries out first dressing in shaft cleaning bar unit 2, and wherein most branch bar is passed through by glazing bar grid, until branch bar outlet row Out;Most of unginned cotton is then transported by caltrop roller one by one, until unginned cotton exports.Caltrop roller is driven by external impetus, can individually be carried out Electrodeless variable-speed is adjusted.
The clear bell unit 7 of unginned cotton outlet;Clear bell unit 7 includes the first sawtooth roller and the first cotton brushing roller;First cotton brushing roller Unginned cotton on first sawtooth roller can be brushed off;In this way, the unginned cotton by experience for the first time, into clear bell unit 7, by first Sawtooth roller is cleared up again, and is assisted by the first cotton brushing roller, and the first sawtooth roller is detached from.
Clear bell unit 7 is connected to unginned cotton recovery unit;Unginned cotton recovery unit includes the first recycling combination 8 and the arranged up and down Two recycling combinations 9, the two height are staggered;First and second recycling combinations include the second sawtooth roller for being mutually matched and the Two cotton brushing rollers;Second cotton brushing roller can brush off the unginned cotton on the second sawtooth roller;In this way, being fallen by clear bell unit 7 heavier Impurity by clearing up twice, recycles unginned cotton therein respectively.
There is the second blower 10 below unginned cotton recovery unit, the air duct connection of the second blower 10 successively unginned cotton recovery unit and Clear bell unit 7, and it is connected to dust cage 16;In this way, the unginned cotton being discharged in clear bell unit 7 is not fallen out to unginned cotton recovery unit, and It is directly to be blowed by wind to dust cage 16, likewise, equally being sent by wind to dust cage by the unginned cotton that the recycling of unginned cotton recovery unit is got 16,
In dust cage 16, (or entering cleaner) is discharged in the broken leaf of dust and part inside dust cage 16 with the wind;Dust cage 16 Bottom is connected to the thin miscellaneous cleaning unit 13 of multi-cascade group;The thin miscellaneous cleaning unit 13 of multi-cascade group has several caltrop rollers being arranged successively With impurities removal stick;Arrangement mode is the direction arrangement tilted upward;One end of caltrop roller is disposed with collecting box 12, the lower section of caltrop roller With impurity recycling bins 11.Caltrop roller is by speed regulating motor or hydraulic motor driving, it can be achieved that individually variable speed adjusting, impurities removal stick Between gap being capable of step-less adjustment.
In order to avoid the interference of the second blower 10, air-valve 15 is closed equipped with second in 16 bottom of dust cage.
Process switching valve 14 is housed between dust cage 16 and the thin miscellaneous cleaning unit 13 of multi-cascade group;Process switching valve 14 can close Dust cage 16 is simultaneously connected to by the communicating passage closed between the thin miscellaneous cleaning unit 13 of dust cage 16 and multi-cascade group with experimental bench outside.
Cotton harvesting impurity elimination experimental bench provided in this embodiment, the course of work are as follows: the unginned cotton after Mechaniaed harvest is put Enter in feeding hopper 3, be uniformly sent by feeding roller 4 and first close air-valve 5, drop down onto the exit of the first blower 6, in the case where wind-force is blowed into Enter in expansion chamber 1, the broken leaf of dust and part passes through the mesh enclosure discharge (or entering cleaner) of expansion chamber 1 with the wind, under settling Unginned cotton enters shaft cleaning bar unit 2, and unginned cotton is exported from top, and branch bar is discharged from bottom;Subsequent unginned cotton enters clear bell unit 7, greatly Part unginned cotton is sent to pneumatic conveying main channel, and a small amount of unginned cotton enters unginned cotton recovery unit surface with impurity, carries out the seed of two-stage Cotton recycling;It is sent again by 10 wind of the second blower, the unginned cotton cleared up can be transported to next cleaning link, initially enter dirt Cage 16, discharge (or entering cleaner) inside dust cage 16, the unginned cotton under settling enter second to the broken leaf of dust and part with the wind Air-valve 15 to be closed, by the position of shift process switching valve 14, changes unginned cotton work flow, "ON" can enter next process, "Off" can be expelled directly out;Shift process switching valve 14 quickly enters the thin miscellaneous cleaning unit 13 of multi-cascade group, seed under "ON" position Cotton is cleared up step by step upwards since bottom, is finally discharged from top into collecting box 12, and impurity is from top to bottom collected and returned into impurity Case 11 is received, the cleaning process before completing unginned cotton cotton ginning.
The present embodiment is to solve cotton picker machine-carried type unginned cotton impurity elimination technology and machine and adopt rear place unginned cotton pretreatment skill The unginned cotton impurity elimination problem of art probes into the working principle of unginned cotton impurity elimination, optimizes unginned cotton pretreatment unit structure and working parameters, And a kind of cotton harvesting impurity elimination experimental bench of innovative design.
The present invention is not limited to the above embodiment the specific technical solution, and in addition to the implementation, the present invention may be used also To there is other embodiments.It is all using equivalent replacement formed technical solution, be the present invention claims protection scope.
