The present application is further described with reference to the following examples and figures, examples of which are as follows: as shown in the attached figures 1-7, the floor cotton air suction type picking machine comprises a frame 11, wherein a traction frame is arranged at the front part of the frame 11, a travelling wheel is arranged at the bottom of the frame 11, and a cotton collecting box 1 is arranged on the frame 11; a cotton inlet and an air inlet are arranged at the bottom of the cotton collecting box 1, the cotton inlet is communicated with a cotton feeding channel 2 in the cotton collecting box 1, and the air inlet is communicated with an air guiding channel 12 in the cotton collecting box 1; a cotton collecting platform 9 is fixedly arranged at the lower part of the front side of the frame, the cotton collecting platform 9 comprises an air blower 5 and an air blowing channel 20 which are arranged at two sides, an air blowing pipe 7 of the air blower 5 is communicated with an air inlet 16 of the cotton collecting platform 9, and an air inlet pipe 4 of the air blower 5 is communicated with the air induction port; the air inlet 16 is the air inlet 16 of the air blowing passage 20, a cotton suction pipe 8 for sucking cotton is arranged between the two air blowing passages 20, and the cotton suction pipe 8 is communicated with the cotton inlet.

As shown in fig. 1, the front lower part of the frame 11 extends forward, the extending part is provided with comb strips 6 arranged transversely along the frame 11, a plurality of vertical downward comb teeth are uniformly distributed in the comb strips 6 at intervals, and the comb strips 6 are positioned at the front side of the cotton collecting platform 9. The cotton on the cotton stalk can be scraped off through the carding strips 6, after the cotton falls on the ground, the air blown out from the air blowing port 19 can blow the ground cotton to the middle part of the cotton collecting platform 9 for collection, and then the ground cotton is sucked into the cotton collecting box 1 through the cotton sucking pipe 8 to complete collection.

As shown in fig. 3, a driving device 3 is arranged at the front side of the frame 11, a transmission shaft 15 is arranged in the frame 11 below the driving device 3, a power input wheel 14 is fixedly arranged on the transmission shaft 15, the power input wheel 14 is driven by a power output wheel 13 of the driving device 3, and two ends of the transmission shaft 15 are respectively connected with power driving shafts of the blowers 5 positioned at two sides of the cotton collecting platform 9. The blower 5 can be driven to work by the driving device 3. The driving device 3 may be one of a diesel engine, a gasoline engine, and an electric motor, the blower 5 is a centrifugal blower 5, and the driving device 3 and the blower 5 are all known in the art, and the specific structure thereof will not be described in detail herein.

Further, the cotton feeding passage 2 is arranged on the inner wall of the front side of the cotton collecting box 1, the upper end opening of the cotton feeding passage 2 is positioned at the middle upper part in the cotton collecting box 1, and the lower end opening of the cotton feeding passage 2 is communicated with the upper end opening of the cotton suction pipe 8 through a connecting pipe 10; an air guide duct 12 is respectively arranged at two sides in the cotton collecting box 1, the air inlet of the air guide duct 12 is positioned at the middle upper part in the cotton collecting box 1, and the air outlet of the air guide duct 12 is communicated with the air inlet pipe 4 of the air blower 5.

As shown in fig. 1, the air guiding duct 12 is arranged along the bottom of the rear wall and the side wall of the cotton collecting box 1, and the air inlet of the air guiding duct 12 is located at the middle upper part of the rear wall of the cotton collecting box 1. This arrangement is suitable for the flap 21 to be arranged on top of the collecting box 1. When the cotton collecting box 1 takes a certain point at the rear part as a pivot and the front part is lifted upwards to be close to 90 degrees, the flip cover 21 naturally loses the shielding effect on the cotton collecting box 1, and the cotton in the flip cover can fall off. However, this method has a disadvantage in that a part of the cotton which is not dropped out may enter the air introducing duct 12 and further enter the blower 5, so that a blocking net is required at the air inlet of the air introducing duct 12. Meanwhile, the structure is relatively complex, the lifting height is large, the danger coefficient is high, but the lifting height is high, and the lifting device can be directly transferred to a transport vehicle.

As shown in fig. 2, the air guiding duct 12 is arranged along the top and the inner wall of the front side of the cotton collecting box 1, and the air inlet of the air guiding duct 12 is located at the rear part of the top of the cotton collecting box 1. This arrangement is suitable for the arrangement of the flap 21 at the rear end of the collecting box 1. When the front part of the cotton collecting box 1 is lifted upwards by taking a certain point at the rear part as a pivot, the flip cover 21 naturally loses the shielding effect on the cotton collecting box 1, and the cotton in the cotton collecting box can fall off. In this way, the cotton does not enter the air guiding duct 12, and a shielding net or a shielding net can be arranged at the air inlet of the air guiding duct 12. Meanwhile, the structure is relatively simple, the lifting height is low, the danger coefficient is low, but the lifting height is low, and cotton can be unloaded to the ground firstly and then transferred to a transport vehicle.

As shown in fig. 4, 5, 6, and 7, the cotton collecting platform 9 includes a top plate 17 fixed on the front lower side of the frame 11, two air blowing channels 20 are symmetrically arranged on both sides of the bottom surface of the top plate 17, air inlets 16 of the two air blowing channels 20 are respectively arranged on both sides of the upper surface of the top plate 17, a cotton suction pipe 8 is fixed in the middle of the top plate 17 between the two air blowing channels 20, and air blowing ports 19 are respectively arranged on the bottom surfaces of the two air blowing channels 20.

Furthermore, the distance between the front ends of the two air blowing channels 20 is large, the distance between the rear ends of the two air blowing channels is small, and the two air blowing channels are arranged on the two sides of the bottom of the top plate 17 in a splayed mode. This is advantageous for blowing the cotton scraped off by the sliver 6 to the ground between the two blowing channels 20, avoiding omission.

Further, the outer side wall of the air blowing channel 20 is an inclined plane with the lower end inclined inwards, the air blowing ports 19 are formed along the length direction of the bottom surface of the air blowing channel 20, the distance between the front ends of the air blowing ports 19 formed in the bottom surface of the two air blowing channels 20 is large, the distance between the rear ends of the air blowing ports 19 is small, and the air blowing ports are arranged in a splayed shape. The outer side wall of the air blowing channel 20 is inclined, so that the wind direction at the air blowing port 19 is changed from vertical to inclined inwards, and the wind direction is integrally concentrated towards the middle of the cotton collecting platform 9. The oblique wind can form reverse cyclone after contacting the ground, and can bring the cotton to roll upwards, which is beneficial to the cotton suction operation of the cotton suction pipe 8.

Furthermore, the air blown out by the two air blowing ports 19 is converged on the middle shafts distributed in the front and the back of the cotton collecting platform 9, and the cotton suction pipe 8 can be arranged at any point on the middle shafts. As shown in fig. 4 and 5, the cotton suction pipe 8 is arranged at the rear side position of the middle shaft, namely, at the rear side position of the middle part of the top plate 17. The cotton suction pipe 8 is arranged at the position, cotton is favorably sucked up, and omission is avoided, but due to the influence of blowing, the cotton is mainly concentrated from the middle rear part to the front part of the center shaft, so that the cotton suction efficiency is possibly lower when the cotton suction pipe 8 is arranged at the rear side of the center shaft. Therefore, as shown in fig. 6 and 7, the cotton suction pipe 8 moves forwards along the central axis and is arranged at the middle rear part of the central axis and in the area where cotton is concentrated, so that the cotton suction efficiency is improved, and omission is avoided.

Further, the ground clearance of the lower port of the cotton suction pipe 8 is smaller than that of the air blowing port 19. The arrangement is also used for improving the suction force of the cotton suction pipe 8 to the cotton and the primary impurity removal capacity. If the lower port of the cotton suction pipe 8 is too high above the ground, especially higher than the blowing port 19, the distance between the lower port of the cotton suction pipe 8 and cotton is increased, which will result in the great reduction of cotton suction efficiency and more impurities.

Furthermore, air exhaust holes 18 are uniformly formed in the middle and the front of the top plate 17. The air outlet 18 can guide the wind blown from the air blowing port 19 to be guided out and prevent the cotton from separating upwards, and in the process, a part of impurities are separated from the cotton to form primary impurity removal.

This application is when using, drags this application through the traction frame and hangs at traction machine rear. After the cotton-collecting box is driven to the field, the driving device 3 is started to drive the air blower 5 to work, the air blower 5 pumps the interior of the cotton-collecting box 1 to negative pressure through the air inlet pipe 4, and meanwhile, air is blown into the air blowing channel 20 through the air blowing pipe 7. Along with the antedisplacement of this application, sliver 6 can scrape the cotton on the cotton stalk and fall, and cotton collection platform 9 then can blow the collection with the cotton that falls to the ground and scrape cotton syntropy cotton collection platform 9 middle part, owing to form the negative pressure in the collection cotton case 1, also form the negative pressure naturally in the cotton pipe 8 of inhaling that links to each other with it, inhale cotton pipe 8 lower port department and form suction to can inhale collection cotton case 1 with the cotton of inhaling cotton pipe 8 lower port. After entering the cotton collecting box 1 through the cotton suction pipe 8 and the cotton feeding passage 2, cotton naturally falls down and is collected at the bottom of the cotton collecting box 1, and cotton suction operation is completed.

The foregoing description is by way of example only and is not intended as limiting the embodiments of the present application. All obvious variations and modifications of the present invention are within the scope of the present invention.
