The lifting type seed cotton cleaning machine is internally provided with a turning plate 17, and the path of seed cotton in the lifting type seed cotton cleaning machine is changed by switching the position of the turning plate 17.
Specifically, as shown in fig. 3, the cleaning machine for the purified seed cotton comprises a frame, and the frame is internally provided with a first rack roller 14, a second rack roller 15, a cotton brushing roller 16, a turning plate 17, a trash discharging rod 18, a steel wire brush 19, a bell blocking plate 20, grid bars 21, a trash discharging auger assembly 22 and the like.
The first rack roller 14 is arranged between the feed inlet 13 and the discharge outlet 23, the second rack roller 15 is arranged below the first rack roller 14, the second rack roller 15 and the first rack roller 14 are in echelon layout, and the second rack roller 15 is arranged far away from the discharge outlet 23 relative to the first rack roller 14; two-stage treatment of seed cotton in the stripping type seed cotton cleaning machine is formed through the second rack roller 15 and the first rack roller 14, and seed cotton is cleaned thoroughly by matching with the echelon layout.
In this embodiment, the diameter of the second rack roller 15 is smaller than the diameter of the first rack roller 14, so that seed cotton is converted from large-scale rotation to small-scale rotation, namely, from coarse impurity removal to fine impurity removal.
The cotton brushing roller 16 is arranged between the first rack roller 14 and the second rack roller 15, and is compact in structure and capable of brushing cotton for the large roller and the small roller.
The first rack roller 14 is circumferentially provided with the ring-blocking plate 20, the steel wire brush 19 and a plurality of impurity discharging rods 18 in sequence, when the seed cotton dropped by the equipment is more, the impurity discharging rods 18 are adjusted towards the axis of the first rack roller 14, so that the cotton covering is facilitated, and the cotton dropping is reduced. When the impurity removing effect is poor, the impurity removing bars 18 are adjusted to be properly far away from the first rack roller 14, and even one group or two groups of impurity removing bars 18 are removed, so that the optimal cleaning effect is achieved.
The second rack roller 15 is circumferentially provided with a wire brush 19 and a plurality of impurity discharging rods 18 in sequence, and since the diameter of the second rack roller 15 is smaller than that of the first rack roller 14, the number of the impurity discharging rods 18 in the circumferential direction of the second rack roller 15 is smaller than that of the impurity discharging rods 18 in the circumferential direction of the first rack roller 14.
A grid bar 21 is arranged below the second rack roller 15, a impurity discharging auger assembly 22 is arranged below the grid bar 21, and impurities are discharged to the impurity discharging auger assembly 22 through the grid bar 21.
The rotating end of the turning plate 17 is positioned at one side of the first rack roller 14, and a bell-blocking plate 20, a wire brush 19 and a plurality of impurity-removing bars 18 are sequentially arranged at the other side of the first rack roller 14. The inner side of the feed inlet 13 is provided with a first limiting part and a second limiting part at intervals, and the first limiting part and the second limiting part can be plate members. The second limiting portion is disposed near the bell-blocking plate 20, and the first limiting portion is disposed far from the bell-blocking plate 20.
When the tail end of the turning plate 17 contacts with the first limiting part to form a first position, seed cotton enters the inside from the feed inlet 13 and is subjected to impurity removal treatment through impurity removal bars 18 on the side surfaces of the first rack roller 14 and the second rack roller 15; when the tail end of the turning plate 17 contacts with the second limiting part to be at the second position, the seed cotton is directly discharged from the discharging hole 23 after entering the inside from the feeding hole 13, namely, the seed cotton is not treated by the stripping type seed cotton cleaning machine.
The working principle of the purifying seed cotton cleaner is as follows:
seed cotton falls onto the turning plate 17 after the previous procedure, slides onto the first rack roller 14 through the turning plate 17, and the racks on the surface of the rack roller hook cotton fibers to drive the seed cotton to rotate along with the first rack roller 14; impurities such as bell shells, cotton leaves and the like cannot be hooked by the racks and can only move along with the rack roller on the surface layer of the rack roller. When the seed cotton hits the trash discharging rod 18, the seed cotton is hooked to continue to rotate along with the rack roller, and the trash such as bell shells and the like is impacted to the trash discharging rod to be discharged and separated from the seed cotton under the action of centrifugal force.
In the process, a small amount of unginned cotton which cannot be hooked and impurities fall onto the second rack roller 15 together, and the racks arranged on the surface of the second rack roller 15 hook the unginned cotton which falls at the first rack roller 14, so that the unginned cotton rotates along with the second rack roller 15. The impurities collide with the impurity discharging rod 18 to be separated from seed cotton under the action of the centrifugal force of the second rack roller 15, and are discharged out of the machine body through the impurity discharging auger assembly 22. In the process of hooking and pulling the rack roller, the cotton brushing roller 16 rotates at a high speed, and the linear speed of the cotton brushing roller 16 is higher than that of the rack roller, so that the cotton brushing roller 16 brushes seed cotton hooked and pulled on the large and small rack rollers into the next process.
The purifying seed cotton cleaner of the embodiment adopts the interaction of the impurity removing rod 18, the steel wire brush 19, the turning plate 17, the large rack roller, the cotton brushing roller 16, the small rack roller, the grid bar 21, the impurity removing auger assembly 22 and the like to separate cotton leaves, bell shells and the like from seed cotton, thereby achieving the aim of removing impurities.
According to the embodiment, the inclined seed cotton cleaning machine is matched with the purifying seed cotton cleaning machine, so that the seed cotton cleaning machine can be horizontally installed on the ground, the overall height is reduced, and the height requirement on a factory building is eliminated. The method is not only suitable for the construction of new buildings and new production lines, but also suitable for the improvement and promotion of old buildings and old production lines. Through many inclined unginned cotton cleaning machines and purification formula unginned cotton cleaning machines, can reduce the quantity that drops of single seed cotton, can pass through multichannel quantity again, reach best cleaning efficiency.
Embodiment two:
the embodiment provides a seed cotton cleaning process, which adopts the seed cotton cleaning device in the first embodiment, and different paths can be selected according to different impurity contents of seed cotton, specifically as follows:
for seed cotton with high impurity content, as shown in fig. 1, the turning plate 17 is positioned at a first position; seed cotton enters the first inclined seed cotton cleaning machine 1 along the direction indicated by an arrow, is discharged from a discharge bin after being cleaned and lifted, and enters the first purified seed cotton cleaning machine 2 through a material conveying channel; in the first stripping type seed cotton cleaner 2, seed cotton is cleaned by a first rack roller 14 and a second rack roller 15, a trash discharging rod 18 and a cotton brushing roller 16.
After seed cotton is cleaned by the first cleaning type seed cotton cleaner 2, the seed cotton is discharged from a discharge hole 23 and enters the second inclined type seed cotton cleaner 3; then sequentially passing through a second stripping type seed cotton cleaner 4, a third inclined type seed cotton cleaner 5 and a third stripping type seed cotton cleaner 6.
As shown in fig. 2, seed cotton with low impurity content enters the first inclined seed cotton cleaner 1 through the previous procedure, the seed cotton falls into the first stripping type seed cotton cleaner 2 through the lifting of the spike roller in the first inclined seed cotton cleaner 1, and seed cotton cleaning is carried out through the first rack roller 14 and the second rack roller 15, the impurity discharging bar 18 and the cotton brushing roller 16.
The second purified seed cotton cleaner 4, the third inclined seed cotton cleaner 5 and the third purified seed cotton cleaner 6 are sequentially passed through in the same way; when seed cotton is cleaner or is cleaned by the first cleaning seed cotton cleaner 2, the second cleaning seed cotton cleaner 4 and the turning plate 17 of the third cleaning seed cotton cleaner 6 are rotated to the second position, seed cotton is directly fed into the inclined seed cotton cleaner without being processed by the rack roller, and finally, the seed cotton is fed into the next working procedure through the discharge hole 23 of the third cleaning seed cotton cleaner 6.
Of course, the number of turning plates at the second position can be adjusted, and the turning plates are specifically arranged according to seed cotton cleaning requirements.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art.
