Abstract

The utility model relates to a corn harvester in agricultural machinery. The utility model is suspended on the side of a tractor. A back three-point suspension bracket of the tractor is provided with a general suspension girder which is fixed with a turning gear box, transmitting the power sideways transmitted by a power transmitting shaft of the tractor. One path is transmitted to a stalk crushing gear box through a group of chain transmission, and another path is transmitted to an ear picking gear box through the chain transmission. The utility model is also characterized in that a granary is at the end of an ear picking roller. After ears are picked, corn ears fall into the granary directly, saving a delivery device. The utility model is also provided with a corn root and stubble breaker.

Description

A kind of side hanging maize harvesting machine

The utility model relates to the reaping machine of agricultural machinery.The fringe of plucking that is corn is specifically gathered in the crops, and corn is plucked fringe in the field, and straw is gone back the field by rotating knife chopping back, finishes the harvest operation of corn.

Have the maize harvesting machine of plucking the fringe function at present, be divided into front positioning type and side-mounted.The line number of its results is had by the 1-4 provisional capital.Its basic structure is for plucking the fringe part, running part, and the silo of dress corncob, self-propelling these several parts are contained on the self-propelling chassis.Underslung generally is by trifilar suspension frame behind the tractor, is assemblied in the back or the side of tractor.It plucks the fringe part generally is to drive paired snapping bar rotation by power to pluck fringe under the help of plucking the fringe plate, is the carrier chain of band moving tooth on pluck the fringe plate, and corncob is dialled to conveying plant, delivers to silo.In the snapping bar front grain lifter is set, is convenient to, draw between snapping bar milpa.And the power transmission pattern is various, and is supporting with design separately.Return crop stocks to the field owing to agricultural development in recent years, thereby when design, mostly have straw mincing and returning to the field device, to satisfy the needs of agricultural production.

The purpose of this utility model is intended to be applicable to delegation or the side-mounted application of two row maize harvesting machines for suspension type maize harvesting machine design one cover general-purpose type hangs transmission device.It is too high to overcome silo, and center of gravity is higher, carries the corncob apparatus structure than defectives such as complexity, thereby reaches simple in structure, uses reliable.

The utility model is to solve by following scheme.On the ball pivot of the trifilar suspension frame horizon bar of tractor, connect a main shaft.Having the suspension crossbeam of two hangers, with bolt hanger is connected on the main shaft, is a firm fixed head at an end that hangs crossbeam, is fixed together with bolt and maize harvesting machine casing.Hang the hanger on the crossbeam, the conversion of the screw relative position on main shaft has changed the relative position of tractor and maize harvesting machine, thereby reaches the delegation's results and two capable gather in the crops general of this suspension arrangement.Be provided with a break-in gearbox on the suspension crossbeam, be made up of the bevel gear of a pair of different numbers of teeth, its input is linked by the power take-off of a gimbal coupling and tractor.Its output is a power transmission shaft, in that bearing supporting is arranged near the fixed head place with the harvest corn engine housing, on the power transmission shaft of the front of bearing, fix one group of chain drive, by drive sprocket with by movable sprocket, transfer motion power is given straw destroyer gearbox, and this gearbox is made up of the pair of straight gear.On the power transmission shaft of bearing back, fix another group chain drive, give the power transmission shaft of plucking the fringe gearbox, drive snapping bar and rice-pulling chain, finish and pluck the fringe function by main passive chain gear transmission power.So far finished the purpose of design first step.The utility model is not established the corncob conveying plant when design, saved the consumption of power, the housing that suspension crossbeam fixed head connects is the left-and-right guard board of straw destroyer just, below the end of snapping bar and rice-pulling chain, left-and-right guard board is joined with the silo base plate, and the space of composition is exactly a silo.Open a mouth in the bottom in this space and just become the mouth of putting out cereal.Be the silo directly formed in the back of snapping bar to have removed the corncob conveying plant with background technology maximum different like this by housing, simple in structure, reduced power consumption, whole unit center of gravity is low, hangs flexibly.For the function of strengthening the straw chopping increases the breaking device, the breaking device is that every capable corn possesses one group, and every group is a boots footwear formula colter, and colter utilizes the colter fixed cover by being bolted on the horizontal square tube on the fixed head.Square tube is fixed on the back rest of maize harvesting machine straw destroyer by connecting plate and fixed head.Colter in fixed cover by bolt.Colter can move up and down in fixed cover like this, to adjust the embedded depth of colter, adjusts degree of depth bolt.Colter is together with colter fixed cover move left and right on the square tube beam then, and to aim at the corn stubble line-spacing, adjustment aligns the back bolt.This colter breaking device and maize harvesting machine join together, and once finish the corncob results and return crop stocks to the field, the fragmentation of root stubble, complete operation does not have in the prior art.Present technique reduces facility and advances the ground number of times, and few ground of pressing has reduced the destruction to soil aggregate, meets the needs of agricultural production.

Being illustrated as a kind of embodiment of the present utility model, is to be applied in two row maize harvesting machines, and supporting tractor is a power more than 50 horsepowers.Embodiment is described further the utility model whereby.
