Description
Field of the Invention
The invention relates to a multi-grade seed cotton heavy impurity cleaning and separating device, and belongs to the technical field of cotton processing machinery.
Background of the Invention
At present, cotton harvesters manufactured by the Deer Corporation and Case Corporation in the U.S. represent the mechanical cotton harvesting technology on a word-class advanced level and typically include traditional cotton harvesters and selective cotton harvesters. On the basis of absorbing foreign advanced technologies, horizontal spindle-type cotton pickers having the advantages of high production efficiency and low impurity rate have been demonstratively promoted in the Xinjiang Corps of China. However, such cotton pickers are not suitable for inland high cotton plants growing at a high density and inland planting technologies and thus cannot be popularized nationwide. Traditional cotton pickers represented by brush roll-type cotton pickers and finger brush-type cotton pickers have the superiority of higher cost performance thanks to their wide application range, low production, usage and maintenance cost and high harvest rate.
In the process of picking cotton, traditional cotton harvesters pick cotton bolls, boll shells and seed cotton at the same time, and processing procedures of removing bolls, boll shells and crushed leaves are mechanically completed in the subsequent stage. Impurities in seed cotton are removed by a principle that large and heavy impurities are removed first and then small and light impurities are removed. Thus, heavy impurity removal is the first most important procedure during seed cotton cleaning.
According to existing traditional cotton pickers, a boll outlet is formed at a seed cotton outlet of a picking platform, and cotton bolls fall onto fields by means of the difference in specific gravity of materials. For example, Chinese Utility Model Patent Application No. 201420224961.6 discloses a cotton boll separation and conveying device which is mounted at the seed cotton outlet of the picking platform, wherein a flow of seed cotton is raised by a cotton raising roller, the seed cotton and cotton bolls are layered by positive-pressure air and gravity, and the cotton bolls on the lower layer enter a cotton boll recovery system via the boll outlet and are finally conveyed into a boll collection box. However, when a large quantity of cotton bolls are recovered, positive-pressure guide air may be formed at the boll outlet, and part of the seed cotton is directly discharged out of the boll outlet, which results in the loss of the seed cotton.
In view of this, Chinese Invention Patent Application No. 201510124608.X provides a high-efficiency low-loss seed cotton boll removal conveying device which replaces positive-pressure air separation with negative-pressure suction separation, so that the loss of seed cotton is significantly reduced, and the recovery rate of cotton bolls is increased. However, in the picking process of the cotton picker, due to the unevenness of the fields, soil hilling may be caused if the picking height is too low and leads to failure to discharge, immature shriveled bolls failing to be separated are mixed into a pre-processor on the cotton picker and may lead to the negative influences of dyeing of the seed cotton, quality reduction of the seed cotton and low impurity removal efficiency.
It can thus be seen that the heavy impurity removal technology still remains simplex and traditional and cannot fulfill a desired removal effect due to soil heeling, incomplete removal of cotton bolls and dyeing of the seed cotton under the variable condition of fields.

The third-stage heavy impurity recovery mechanism comprises a tangent guide grating mounted at the upper end of the pipeline, an impurity discharging element, an air feeder, a third-stage guide plate, a guide hood located at the tail end of the third-stage guide plate, and a three-stage heavy impurity collector located at the tail end of the pipeline, wherein the impurity discharging element is located at the upper end of the rear portion of the third-stage heavy impurity collector, is used for regulating the impurity discharge quantity, and is an impurity discharging damper, and the head end of the third-stage guide plate is located at the second-stage heavy impurity separation opening and forms the second-stage heavy impurity separation opening together with the tail end of the second-stage guide plate.
As an improvement of the above technical solution, a cotton raising roller body is a cylindrical or polygon column.
As an improvement of the above technical solution, linear or arc spike-like teeth are uniformly distributed on the surface of the cotton raising roller in the axial direction.

In this embodiment, a cotton raising roller 1 body is a cylindrical or polygonal column, or other available column structures, and linear or arc spike-like teeth are uniformly distributed on the surface of the column structure of the cotton raising roller 1.
In this embodiment, the boll-collection belt conveyor 7 is hinged to a front axle of the cotton picker, floats with rising or falling of the picking platform and comprises an annular belt 7-1 and scraper plates 7-2 on the annular belt 7-1.
In this embodiment, the tangent guide grating 9 is a grating bar 9-1, or a porous plate 9-2, or the combination of the grating bar 9-land the porous plate 9-2 and has a circular or polygonal section.
In this embodiment, a flow of seed cotton picked by the cotton picker is conveyed to the multi-grade seed cotton heavy impurity cleaning and separating device through the picking platform and enters the cotton raising roller 1 which rotates anticlockwise, and the seed cotton flow can be rapidly dispersed after being thrown and knocked by the cotton raising roller 1 and moves backwards and upwards; the picking platform may collide with the uneven earth surface in the picking process and collects a small quantity of heavy impurities such as soil and stone, and these heavy impurities will be discharged via the first-stage heavy impurity separation opening first; cotton bolls which have a large size and a small weight against soil and stone will pass over the first-stage heavy impurity separation opening to reach the second-stage heavy impurity separation opening to be discharged to fall onto the boll-collection belt conveyor 7; light seed cotton moves upwards along the inner wall of the pipeline under the negative-pressure suction effect of the air jet device 4; the seed cotton flow is delivered by the air pressure to reach a position above the three-stage heavy impurity collector 12, at this moment, the light seed cotton is guided to enter the seed cotton pre-processor on the cotton picker along the tangent guide grating 9, and heavy immature shriveled bolls and a small quantity of branches are blocked by the impurity discharging damper 13 to move downwards to the three-stage heavy impurity collector 12; and a small quantity of simple seed cotton grains will be recovered under the effect of air supplied by the air feeder 11 below the third-stage heavy impurity collector 12 to be conveyed into the seed cotton flow again, so that seed cotton with an extremely low heavy impurity rate is obtained. As can be seen from the structural cooperation of all parts, small simple seed cotton grains are brought back into the seed cotton flow again instead of being carried out with the heavy impurities, so that the cleaning efficiency is significantly improved, and waste is reduced.
The invention is not limited to the above embodiment, and all technical solutions obtained by equivalent substitution should fall within the protection scope of the invention.
