Description

Technical Field

[0001] This utility model relates to a multi-position single-unit combined picking platform used on a cotton harvester, belonging to the technical field of cotton picking (A01D 46 / 08). Background Technology

[0002] Existing cotton harvesters typically employ a single picking platform, a combination of two single picking platforms (a double-unit picking platform), or a multi-unit picking platform composed of multiple single picking platforms. Double-unit and multi-unit picking platforms consist of two or more single picking platforms arranged side-by-side, allowing for the simultaneous harvesting of two or more rows of cotton in a field. However, the two or more single picking platforms in existing double-unit and multi-unit picking platforms are often fixed to the harvester's chassis and frame, meaning they cannot move laterally on the harvester. This fixed configuration is unsuitable for cotton fields with varying row spacing. Furthermore, existing picking platforms are not ideal for removing impurities such as cotton branches during the harvesting process. Summary of the Invention

[0003] The technical problem to be solved by this utility model is: how to make double or multi-body picking platforms adaptable to cotton fields with different row spacing, while making the cleaning of picked cotton with branches more effective.

[0004] The technical solution proposed by this utility model to solve the above-mentioned technical problems is as follows: A multi-unit combined picking platform for a cotton harvester, hinged to the front end of a tracked chassis via a suspension frame, includes at least two parallel picking units, a transverse integrated conveyor, and a pneumatic conveying channel connector. Each picking unit includes a pair of separators, two sets of parallel picking rollers, a pair of longitudinal augers, and a first hydraulic motor driving the longitudinal augers. The picking rollers and longitudinal augers are arranged in parallel vertically within a longitudinal frame, and the separators are connected to the front of the longitudinal frame. The transverse integrated conveyor is located at the rear of the longitudinal frame and below the outlet end of the longitudinal augers. The transverse integrated conveyor includes a transverse frame, two coaxial transverse augers located within the transverse frame and spiraling in opposite directions, a second hydraulic motor driving the transverse augers, and two hydraulic cylinders. The hydraulic cylinders are located at the lower front of the transverse integrated conveyor, and the number of hydraulic cylinders is equal to the number of picking units. The piston rods of the hydraulic cylinders are connected to the transverse frame. The pneumatic conveying channel connector includes a cotton conveyor... The system includes a short cotton conveying pipe, a cotton-picking roller located inside the short cotton conveying pipe, and a pneumatic acceleration pipe. The front end of the short cotton conveying pipe is connected to the outlet port of the transverse integrated conveyor, and the rear end of the short cotton conveying pipe is connected to the pneumatic conveying channel. The bottom of the longitudinal frame has two parallel sliding plates, one at the front and one at the rear. The lower sliding plate at the front consists of two parallel double straight plates, while the higher sliding plate at the rear consists of a single plate bent in an S-shape. The top of the transverse frame has two parallel guide rails, a front guide rail and a rear guide rail. The double straight plates of the low-position sliding plate are respectively inserted into the front and rear sides of the front guide rail, and the high-position sliding plate is inserted into the rear side of the rear guide rail. A first waist-shaped perforated plate is attached to the outer side of the rear straight plate of the double straight plates, and a second waist-shaped perforated plate is attached to the rear side of the single plate. The first waist-shaped hole in the first waist-shaped perforated plate and the second waist-shaped hole in the second waist-shaped perforated plate are corresponding to each other and are of equal length. A first pin and a second pin are respectively provided on the rear side of the front guide rail and the rear guide rail, and the first pin and the second pin are respectively inserted into the first waist-shaped hole and the second waist-shaped hole.

[0005] Furthermore, when the piston rod of the hydraulic cylinder extends or retracts, the low-position sliding plate and the high-position sliding plate slide on the front guide rail and the rear guide rail respectively, and the first pin and the second pin move in the first waist-shaped hole and the second waist-shaped hole respectively, pushing the picking unit to move no more than the length of the waist-shaped hole.

[0006] Furthermore, the bottom of the longitudinal frame is fully equipped with a first grid, the bottom of the transverse frame is fully equipped with a second grid, and the bottom of the cotton conveying pipe is fully equipped with a third grid. In this way, cotton branches and other debris separated during the longitudinal auger fall to the ground through the first grid for initial cleaning; further separation during the transverse auger allows for a second cleaning through the second grid; and finally, further separation through the picking roller allows for a third cleaning through the third grid. This three-stage cleaning process throughout the cotton harvesting process significantly improves the cleaning effectiveness.

[0007] The beneficial effects of this utility model are: (1) Since the longitudinal box frame containing the picking roller group and the longitudinal auger and the transverse box frame containing the transverse auger form a sliding plate on the upper and lower surfaces that is inserted into the guide rail, and the transverse box frame is pushed by the hydraulic cylinder, the picking unit moves a limited distance in the transverse direction, thereby adapting to the needs of cotton picking in cotton fields with different row spacings. (2) Since the three processes of longitudinal separation, transverse separation and final cotton picking separation of the picking platform are screened in time with three grids, compared with the existing system where the bottom is covered by steel plates and can only store the separated cotton branches and other debris, this invention cleans the separated cotton branches and other debris more thoroughly and effectively.

In this embodiment, there are two hydraulic cylinders 2-3 and two harvesting units. The piston rod of the hydraulic cylinder 2-3 is connected to the transverse frame. Figure 6 As shown, the pneumatic conveying channel connector 3 includes a cotton conveying short pipe 3-1, a cotton picking roller 3-2 disposed within the cotton conveying short pipe 3-1, and a pneumatic acceleration pipe 3-3. The front port of the cotton conveying short pipe 3-1 is connected to the outlet port of the transverse integrated conveyor 2, and the rear port of the cotton conveying short pipe 3-1 is connected to the pneumatic conveying channel. Figure 2 and Figure 7 As shown, the bottom of the longitudinal frame 1-5 is provided with two parallel sliding plates. The lower sliding plate 1-6, located at the front, consists of two parallel double straight plates, while the higher sliding plate 1-7, located at the rear, consists of a single plate bent in an S-shape. Figure 6 and Figure 7 As shown, the top of the transverse frame 2-5 is provided with two parallel guide rails, namely the front guide rail 2-6 and the rear guide rail 2-7; the double straight plates of the low-position sliding plate 1-6 are respectively inserted tightly against the front and rear sides of the front guide rail 2-6, and the high-position sliding plate 1-7 is inserted tightly against the rear side of the rear guide rail 2-7. Figure 7As shown, a first oblong perforated plate 1-6-1 is attached to the outer side of the rear straight plate of the double straight plate of the low-position sliding plate 1-6, and a second oblong perforated plate 1-7-1 is attached to the rear side of the single plate of the high-position sliding plate 1-7.
