Special bionic comb for picking grain in ridges and furrows

Abstract

The invention provides a bionic comb tooth special for furrow field stalk picking. The bionic comb tooth special for furrow field picking comprise a first spring, a second spring, a tooth head and a fixing end. The fixing end is connected to the tail end of the first spring and used for being fixedly connected with the front end of a header of a harvester. The first spring and the fixing end are both horizontally arranged. The first spring is used for being arranged on a fixing tooth of a reciprocating cutter assembly of the header in a sleeving mode, the front end of the first spring is connected to the tail end of the second spring through an elastic part stretching downwards, and the tooth head is connected to the front end of the second spring. The bionic comb tooth is simple in structure, high in reliability and good in adaptive capacity.

Description

technical field [0001] The invention relates to a special bionic comb for picking up crops in furrows and furrows. Background technique [0002] When a combine harvester is used to harvest crops or stalks in the field, there will be many lodging stalks in the field, and the lodging stalks are difficult to be collected by the header of the harvester, especially in fields with ridges. The stalks are basically crushed under the wheels by harvesters. [0003] The Chinese invention with the application publication number of CN 104335770 A discloses a freely swinging grain picking device for harvesting lodging corn. The share shoe at the front end of the swinging grain picking device can directly contact the ground, and can be adjusted according to the ground conditions under the action of a spring. Change and swing freely, so the lodging corn can be collected, which not only improves the harvesting efficiency, but also reduces the waste of grain. It is easy to operate and can be...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the complex situation in the corn field, the ground is uneven and there are many stones, only one connecting plate is used to connect with the cutting platform. Connection point to header is easily damaged

[0005] 2. Its structure is complicated, and it is welded together by multiple parts. The connection of the spring is relatively fragile and easy to disconnect

[0006] 3. The whole harvester is horizontal and cannot fit well with the furrows in the field, and cannot pick up the grass at the bottom of the furrows

[0007] 4. Only one spring is used to adapt to the terrain, and the spring often has a large swing, resulting in a short service life of the spring
