Description

corn harvester

technical field

The utility model belongs to the field of agricultural mechanical devices, in particular to a grain raiser for a corn harvester.

Background technique

Corn is a crop with a wide planting area in my country. For a long time, corn harvesting is mainly carried out manually, which is not only low in labor efficiency but also labor intensive, time-consuming and laborious. With the popularization of agricultural machinery, corn combine harvesters have been widely used and popularized. However, the existing corn harvesters are the best for harvesting the ears on the upright corn stalks. If the corn stalks are lodging before harvesting, the existing corn The harvester cannot separate the corn stalks from the ears through the header, resulting in omissions during the picking process.

Contents of the invention

The purpose of the utility model is to provide a grain lifter for a corn harvester, which can lift up the lodging corn stalks, improve the picking rate of corn ears by the corn harvester, and has low manufacturing cost and simple maintenance.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

The utility model discloses a grain lifter for a corn harvester, which comprises a reversing box, a longitudinal transmission shaft, a bracket, a straw, and a transverse transmission shaft, wherein a reversing box is arranged at the connection between the longitudinal transmission shaft and the transverse transmission shaft , the transverse transmission shaft is connected with the straw through the reversing box, and the straw is provided with a spiral structure.

Furthermore, the straw described in this application is provided with a left-hand helical structure protruding from the surface.

Further, the bracket described in this application includes a top bracket welded part and a front bracket welded part, the front bracket welded part is connected with the bottom end of the straw, and the top bracket welded part is connected with the upper end of the transverse transmission shaft. The commutation box connection.

Further, the straw described in this application is arranged in the advancing direction of the grain divider.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model is arranged at the front end of the corn harvester in the running direction of the corn harvester, and is used to lift the lodging corn stalks through the spiral action of the spiral structure on the stalk, and when the corn harvester advances, the corn ears are cut by the header. Harvesting improves the ear picking rate of the corn harvester for corn stalks in different growth states, and the utility model has the advantages of simple structure, convenient installation and adjustment, high stability and easy maintenance.

detailed description

The technical solutions described in the present application will be further described below in conjunction with the drawings and embodiments.

Embodiment 1: a kind of grain raising device for corn harvester, comprising reversing box 1, longitudinal transmission shaft 2, support, straw 4, transverse transmission shaft 7, wherein longitudinal transmission shaft 2 and transverse transmission shaft 7 joints are uniform A reversing box 1 is provided, and the transverse transmission shaft 7 is connected with the straw 4 through the reversing box 1, and the helical structure is arranged on the straw 4.

Embodiment 2: a kind of grain raising device for corn harvester, comprising reversing box 1, longitudinal transmission shaft 2, support, straw 4, transverse transmission shaft 7, wherein longitudinal transmission shaft 2 and transverse transmission shaft 7 joints are uniform A reversing box 1 is provided, and the transverse transmission shaft 7 is connected with the straw 4 through the reversing box 1, and the helical structure is arranged on the straw 4. The straw 4 is provided with a left-hand helical structure protruding from the surface. Described support comprises top support welding part 3 and front support welding part 5, and described front support welding part 5 is connected with the bottom end of straw 4, and top support welding part 3 is connected with the replacement on the transverse transmission shaft 7. Connect to box 1. The straw 4 is arranged in the advancing direction of the grain divider 6 .

In view of the foregoing embodiments, during use of the utility model, the transverse drive shaft 7 is fixed in the forward direction of the grain divider 6 of the corn harvester through the top support weldment 3 and the front support weldment 5, and the longitudinal drive shaft 2 It is connected through the power unit of the reversing box 1, and converts the power of the whole machine into the power of the longitudinal transmission shaft 2. Grass stalks 4 are correspondingly arranged on the box 1 respectively, and the rotary motion of the transverse transmission shaft 7 is converted into the rotary motion of the stalks 4 .

The helical structure on the corn stalk 4 can make the lodging corn stalks stand upright under the action of the screw mechanism, and then harvest and harvest corn ears through the header of the corn harvester, which improves the applicable scope of the corn harvester. and picking rate, reducing the labor intensity of manual secondary picking.
