Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, and it is to be understood that the described embodiments are merely illustrative of some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

referring to fig. 1 and 2, the grass discharge device of the corn harvester of the present invention comprises an elevator, a fan 6, a stalk discharge roller device 4, a secondary chopping device 2 and a grass discharge port 1, wherein the fan 6 is arranged below the elevator for providing uniform wind force upwards along the elevator; the stalk discharging roller device 4 is arranged on one side of the outlet of the elevator, the secondary chopping device 2 is arranged on one side of the stalk discharging roller device 4 far away from the elevator, and the grass discharging port 1 is arranged on one side of the secondary chopping device 2 far away from the stalk discharging roller device 4 and is used for discharging chopped straws and weeds; and a fruit ear protection plate 5 is arranged obliquely below the stem-arranging roller device 4.

Referring to fig. 2, in the present embodiment, the stem-row roller device 4 includes a pair of stem-row rollers 7 disposed up and down, and the ear protection plate 5 is circular arc-shaped and disposed concentrically with the stem-row roller 7 below.

In the harvesting process, the corn ears and the broken corn straws which are sent into the elevator by the cutting table of the corn machine are conveyed to the grass discharging device of the corn machine by the elevating chain harrow of the elevator. Sundries such as broken corn stalks, corn bracts and the like are pulled, discharged and chopped through the stalk discharging roller device 4 and the secondary chopping device 2, and are sent to the grass discharging port 1 under the action of the fan 6 to be discharged; due to the rapid rotation of the lifting chain harrow, the corn ears with different sizes are easily thrown onto the stem discharging roller 7 which rotates rapidly along the throwing track 8, so that the corn seeds are damaged. Due to the existence of the ear protection plate 5, the corn ears are prevented from impacting the fast rotating stem-arranging roller 7, and the integrity of the corn ears is ensured.

Referring to fig. 1, 3 and 4, an ear distributing plate 3 is arranged below the ear protecting plate 5, the ear distributing plate 3 comprises a left distributing plate 31 inclined to the left and a right distributing plate 32 inclined to the right, the left distributing plate 31 is fixed with the grass discharge opening 1 through a first bending plate 33, and the right distributing plate 32 is fixed with the grass discharge opening 1 through a second bending plate 34. In the past, corn ears intensively enter the middle part of the peeling mechanism, and the quantity of the corn ears on two sides is small. The corn ears fall on the ear distributing plate and are uniformly distributed in the peeling mechanism for peeling under the action of the ear distributing plate, so that the performance of the peeling machine is fully exerted, and the peeling rate and the operation efficiency are improved.

In the present embodiment, the angle between the left distribution plate 31 and the right distribution plate 32 is 105 ° to 120 °. The bending angles of the two sides of the ear distributing plate are reduced, so that the whole height of the ear distributing plate is reduced and smooth, the single-side centralized distribution of corn ears is avoided, the uniform distribution of the two sides is ensured, the corn ears enter the peeling mechanism more smoothly and uniformly, the peeling effect and the peeling efficiency of the corn ears are ensured, the unnecessary abrasion of the peeling roller is avoided, and the service life of the peeling roller is prolonged.

In this embodiment, the elevator is an elevator chain rake and the fan 6 is a volute fan.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
