Detailed Description

As shown in fig. 1-5, the present invention discloses a cotton harvester, the components of which are placed on a frame 15 supported by wheels 10 and 11.

The picking process comprises the following steps: the harvester is when the operation in the cotton field, the cotton is picked by picking platform 1, get into storage cotton room 5 by advancing cotton mouth 4 through pipeline 2, the cotton in storage cotton room 5 is the cotton mould packing room that the fixed time ration got into and is constituteed by packing room front portion 6 and packing room rear portion 8, after the cotton mould size reached the setting value, start the membrane system that twines, after twining the membrane, by packing room open and shut hydro-cylinder 12 effect, use interlinkage pivot 7 as the center of rotation, open packing room rear portion 8, unload cotton bracket 9 simultaneously and fall, catch the cotton mould, and arrange it to ground.

A transportation mode: the height of the cotton storage chamber 5 and the height of the cotton conveying pipeline 2 are reduced under the simultaneous action of the cotton storage chamber lifting oil cylinder 13 and the conveying pipeline lifting oil cylinder 14, and the height of the front part 6 of the packing chamber and the height of the rear part 8 of the packing chamber are reduced under the action of the packing chamber opening and closing oil cylinder 12 and the cotton unloading bracket 9, so that the proper height required by transportation is achieved.

In order to facilitate the maintenance of machine equipment, the machine equipment can be carried along with a vehicle, and the maintenance can be carried out anytime and anywhere, maintenance platforms are arranged at the back of a vehicle cab and on the two peripheral sides of a cotton storage chamber and a cotton die packing chamber, and comprise a detachable right side platform 16 and a detachable left side platform 17, so that the maintenance and the overhaul of the high position of the equipment are facilitated. After the disassembly, the width of the equipment is reduced, and the road transportation is facilitated.

The bale chamber front 6 is pivotally connected to the frame 15 so as to be swingable between an upright field operating position, a rearward and downward transport position, and a shipping position in which the bale handling apparatus is at ground level. Hydraulically operated latches are provided on the frame 15 and the front lower portion of the bale chamber front 6 so that the bale chamber front 6 can be locked in an upright field work position. Be located the baling press both sides and be equipped with baling chamber open and shut hydro-cylinder 12, lock in upright position at baling chamber front portion 6, and when baling chamber open and shut hydro-cylinder 12 completely returned, this baling chamber front portion 6 and baling chamber rear portion 8 butt joint form the cotton mould baling chamber that upwards extends from the frame.

An upper connecting rod 18 is connected and arranged between the upper ends of the two opposite sides of the cotton mold packing chamber, a lower connecting rod 19 is connected and arranged between the upper part of the front part 6 of the packing chamber and the lower part of the rear part 8 of the packing chamber, the lower end of the opening and closing oil cylinder 12 of the packing chamber is movably connected to the lower part of the front part 6 of the packing chamber, and the end part of the hydraulic rod is movably connected to the lower connecting rod 19. The above-mentioned linkage thus allows the rear bale chamber part 8 to be pivoted relative to the front bale chamber part 6 between a closed position for forming the bale and an open position for releasing the bale, the upper parts of the two parts being substantially in abutment when in the closed position; when the packing chamber opening and closing oil cylinder enables the packing chamber rear part 8 to swing towards the opening position, the upper connecting rod enables the packing chamber rear part 8 to cross the upper part of the packing chamber front part 6; wherein in the closed position the upper link is generally horizontal and the lower link is angled.

Between the lower part of the front part 6 of the baling chamber and the lower part of the rear part 8 of the baling chamber, a door locking device is provided, which automatically operates and comprises a latch plate 20, which latch plate 20 is fixed to the lower end of the rear part 8 of the baling chamber, and which latch plate 20 has a hook 21 protruding downward to the left. The latch receiving portion 22 is fixed to the lower end of the front portion 6 of the baling chamber in alignment with the latch plate 20, which is a right-angled protrusion. The hook 21 is locked to the member 22 when the baling chamber rear portion 8 is swung down to the closed position. The weight of the rear part 8 of the baling chamber keeps the locking means in the locked position until the operator extends the hydraulic cylinder arrangement. When the hydraulic cylinder begins to extend, the baling chamber rear portion 8 moves obliquely upward as the lower link is initially tilted, and the hook 21 disengages from the member 22.

Detachable right side platform and left side platform are installed additional in cotton picker main part both sides, when normal field operation and need maintenance, all can observe, overhaul, maintain the eminence of equipment with the help of the platform. In the transport mode, the right side platform and the left side platform can be dismantled, reduce the transportation width, increase trafficability characteristic.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
