Full-hydraulic-drive high-ground-clearance central-laying rape cutting and drying platform

Abstract

The invention provides a full-hydraulic-drive high-ground-clearance central-laying rape cutting and drying platform which is always horizontal with the ground, has the same stubble cutting height and is used for laying rape to the center after the rape is cut down. The header comprises a header frame, and a hanging mechanism composed of a transverse cutter, a reel, a conveying mechanism, a driving mechanism, a rotating frame and a fixing frame is arranged on the header frame. The rotating frame comprises a U-shaped groove and a front vertical beam; the fixing frame comprises a rear cross beam and a rear vertical beam; a main beam of the header frame is arranged in the U-shaped groove; the lower end of the front vertical beam is connected with the lower part of the rear part of the header frame through a pluggable bolt; one side wall of the U-shaped groove is rotationally connected with the rear cross beam through a pin shaft; height sensors are arranged on the two sides of the header frame. The two ends of the double-acting oil cylinder are hinged to the rotating frame and the fixed frame respectively, the height sensor is electrically connected with the controller, and the controller processes signals of the height sensor, then controls the double-acting oil cylinder to act and drives the rotating frame to rotate around the pin shaft relative to the fixed frame, so that the distances between the two sides of the header and the ground are consistent.

Description

technical field [0001] The invention relates to a fully hydraulically driven high-gap central laying rape cutting and drying platform, which can be matched with a high-gap self-propelled chassis or a high-gap tractor. The working parameters of the cutting platform can be adjusted steplessly. The need for high-efficiency swathing and sunning of tall and large rapeseed in the Yangtze River Basin, especially to meet the needs of laying rapeseed in the middle of the high gap in the area with many uneven drainage ditches in the southern rice oil tanker cropping area of ​​my country, belongs to the field of agricultural machinery technology. Background technique [0002] Rapeseed is the most important oil crop in my country, providing more than 50% of domestic edible oil. The annual planting area in the country is about 100 million mu. The Yangtze River Basin is the main production area of ​​winter rapeseed, accounting for 90% of the area. Rice tankers are the main planting mode. R...

AI Technical Summary

Problems solved by technology

The common harvesting methods of rapeseed are divided into two methods: combined harvesting and segmented harvesting. Combined and segmented harvesting have obvious advantages and disadvantages. Due to the constraints of region, climate and planting and operation scale, the two harvesting methods of rapeseed are both applied in production in my country and Both ways will coexist for a long time

[0003] Rapeseed windrower is one of the important machines in rapeseed section harvesting operation. Rapeseed windrower with various structures has been developed in China in recent years, such as Publication No. The rapeseed windrower of CN101822149A adopts a crawler-type low-gap chassis and lays on the side, but there are problems such as difficulty in opening the first row and mutual involvement between rape plants, resulting in poor laying consistency, poor transportation, and low operating efficiency.

CN105028414B relates to a windrower for double-sided back-laying of rapeseed, which adopts a combination of horizontal and vertical directions, adopts a double-sided back-laying method, and lays on two sides in one operation, and the amount of laying on one side is small, which increases the difficulty of picking up in the later stage, which is not conducive to Subsequent picking and harvesting operations

The existing high-gap wheel-type large-scale central laying windrower in the north and the high-gap large-scale rapeseed windrower imported from abroad have poor adaptability to tall plants with many branches and rapeseed. The wheeled chassis has poor passability under the condition of heavy soil, and the height of the two sides of the stubble is not consistent.

Due to the lack of suitable rapeseed harvesting equipment, the existing rapeseed areas in the small plots and uneven ground in the Yangtze River Basin adopt combined harvesting, and mainly adopt the segmented harvesting method of manual swathing and manual feeding into combine harvesters. , more labor, strong labor
