Description

The corn straw harvesting machine

Technical field:

The utility model relates to small-scale agricultural machinery, especially a kind of corn straw harvesting machine.

Background technology:

At present, how the stalk behind the harvest corn is stored up by a large amount of green grass or young crops as livestock feed.Traditional corn straw harvesting mode adopts the hand harvest, and labour intensity is big, and efficient is low, influences the timely blue or green storage of maize straw.And existing corn straw harvesting machinery mostly is big machinery, complex structure, cost and maintenance cost height, especially incompatibility small-sized plot operation.

Summary of the invention:

The utility model is intended to address the above problem, and a kind of small volume and less weight be provided, be not subjected to field landforms restriction, harvesting efficiency height, harvesting back stalk put neat corn straw harvesting machine.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of corn straw harvesting machine, comprise walked frame, transmission support, final drive shaft, cutter axis, cutterhead, the transmission support is propped up with two tubulars that are fixed on this platform below by the final drive shaft mounting platform and is configured to, two tubular supports are connected with walked frame by adjustable crane, described platform is equipped with gearbox on it, on its power shaft of this gearbox power wheel is housed, on its output shaft pinion is housed, final drive shaft is horizontally placed on the described platform, and the gear wheel with described pinion is housed on it; Cutter axis places in the described tubular support, the bevel gear that is meshed with propeller-parachuting gear on the final drive shaft is equipped with in its upper end, the cutterhead that is the annular saw sheet is equipped with in its lower end, and this cutterhead top is close to its card and is fixed with identical with its number of teeth, as to be used to draw in stalk small tooth plate.

Compared with prior art, the beneficial effects of the utility model are: because therefore the host machine part small volume and less weight can be installed on the small tractor front end by walked frame, adjust the main frame height by adjustable crane, so that suitable harvesting operation or walking; By the tractor outputting power, drive the rotation of final drive shaft and cutter axis, to finish the function of knife cutting maize straw.Because small tractor walking, circuitous flexible, so the suitable all kinds of ground typed operations of this machine, the plot operation of especially scattered small size more is better than large-scale grain header.This machine is simple in structure, and cost is low, and is easy to maintenance, and the operating efficiency height is easy to rural households and applies.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

A kind of corn straw harvesting machine, by walked frame 1, tubular support 2, cutterhead 3, small tooth plate 4, cutter axis 5, platform 6, final drive shaft 7, bevel gear 8, propeller-parachuting gear 9, power wheel 10, gearbox 11, pinion 12, gear wheel 13, bearing and bearing block 14 thereof, platform cover 15, adjusting rod 16, regulate pin-and-hole 17, bearing pin 18, support arm 19, pulley 20, pulling rope 21, positional operand vertical pole 22 parts such as grade are formed, two tubular supports 2 are vertically fixed on both sides, platform 6 below, the common transmission that constitutes host machine part is supported, this transmission is supported by adjustable crane and is connected with walked frame 1, and walked frame 1 is installed in the front end of small tractor.

Described platform 6 is equipped with gearbox 11 on it, on these gearbox 11 its power shafts power wheel 10 is housed, and this power wheel 10 is a belt pulley, is connected with the power wheel of tractor by belt.Pinion 12 is housed on the output shaft of gearbox 11, and final drive shaft 7 laterally is installed on the platform 6 by bearing and bearing block 14 thereof, and the gear wheel 13 that meshes with described pinion 12 is housed on it, and propeller-parachuting gear 9 is installed at two ends respectively; Be vertically installed with cutter axis 5 in the described tubular support 2, platform 6 is passed on these cutter axis 5 its tops, its bearing block is connected with platform 6, the bevel gear 8 that is meshed with propeller-parachuting gear 9 on the final drive shaft 7 is equipped with on cutter axis 5 tops, the cutterhead 3 that is the annular saw sheet is equipped with in its lower end by umbellate form pressure bearing spare, this this umbellate form pressure bearing has clasp in it, can make in itself and the bearing to overlap fastening, so that cutterhead 3 is tightened on cutter axis 5; Described cutterhead 3 tops are close to its card and are fixed with identical with its number of teeth, as to be used to draw in stalk small tooth plate 4.Distance equals the distance on two corn ridges between two cutterheads, 3 center distance that is two cutter axis 5, during work, two cutterheads 3 rotate in opposite directions, maize straw is cut off, small tooth plate 4 together rotates with cutterhead 3, the maize straw that cuts off is dialled to two cutterheads, 3 centre positions, simultaneously since machine in walking forward, so maize straw by root backwards, point forward along the side of moving ahead in good order to lying low in ground.

In the present embodiment, adjustable crane is made up of support arm 19, adjusting rod 16, bearing pin 18, pulling rope 21, support arm 19 1 ends and walked frame 1 are fixing, the other end and adjusting rod 16 1 ends are hinged by bearing pin 18, adjusting rod 16 is provided with one and teases and ridicule joint pin-and-hole 17, adjusting rod 16 other ends and tubular support 2 are fixing, and pulling rope 21 1 ends and tubular support 2 are fixing, and the other end is connected with positional operand vertical pole 22 by the pulley 20 that is installed on the walked frame 1.Positional operand vertical pole 22 is arranged at position of driver, before the work of this machine, earlier support arm 19 and adjusting rod 16 are fixed it in adjusting rod 16 a certain adjusting pin-and-holes 17 by bearing pin 18, pulling rope 21 then comes up, make cutter axis 5 perpendicular to ground, that is cutterhead 3 is parallel to the ground, at this moment, cutterhead 3 meets the maize straw off-position just with ground distance, then begins to gather in operation; When stopping operation, move positional operand vertical pole 22, pull back pulling rope 21, and select suitable adjustable pin-and-hole 17, support arm 19 and adjusting rod 16 are fixed it by bearing pin 18, this moment, cutterhead 3 can be raised the distance with ground, was convenient to walking.
