Problems solved by technology

Chinese patent CN109699287A discloses a leaf vegetable harvester with the function of harvesting height adjustment and its control method. According to the signal detected by the infrared distance measuring sensor, the electric push rod is controlled to expand and contract, and the lifting platform is controlled to expand and contract according to the signal detected by the ultrasonic sensor. However, the executive device of the harvester still only realizes longitudinal profiling and does not have the function of horizontal profiling, and due to the complex environment of the ridge surface, the direct use of the ultrasonic sensor to detect the ridge surface information has a large error
At the same time, due to the advanced detection information leading to the advanced detection information, the adjustment of the height and position of the header is inaccurate;

Embodiment 1

[0102] figure 1 , figure 2 , image 3 , Figure 4 It is a preferred embodiment of the header profiling device, the header profiling device includes a profiling detection assembly 1, a header profiling adjustment assembly 3, a header lifting execution assembly 4, a cutting The platform chassis hinge assembly 5 and the control system 9; the profiling detection assembly 1 is installed in front of the header 2; the header profiling adjustment assembly 3 is installed laterally and symmetrically on the front bottom of the header 2 end; two sets of the header lifting executive assembly 4 are laterally symmetrically installed between the header 2 and the chassis 6; the header chassis hinge assembly 5 is laterally symmetrically installed between the header 2 and the chassis 6 The rear end of the room; the control system 9 is respectively connected with the profiling detection assembly 1, the header 2, the header profiling adjustment assembly 3, the header lifting execution assembly...

example 1

[0111]Example 1: The header lifting actuator assembly 4 includes a tripping sleeve 4-1 and a header lifting actuator 4-2. The rod end of the tripping sleeve 4-1 is rotatably connected to the bottom of the header 2, and the hole end of the tripping sleeve 4-1 is slidably connected to the elongated end of the header lifting actuator 4-2 to form a straight line vice. The installation end of the header lifting actuator 4 - 2 is rotatably connected to the chassis 6 . When the extension end of the header lifting actuator 4-2 reaches the lowest position, a free floating telescopic state is formed between the header lifting actuator 4-2 and the tripping sleeve 4-1, that is, the The header lifting actuator 4-2 no longer exerts thrust on the trip sleeve 4-1; when the extension end of the header lifting actuator 4-2 reaches the highest position, the formed free-floating telescopic state becomes To support the fixed state, that is, the header lifting actuator 4-2 lifts the header 2 to a...

example 2

[0112] Example 2: The header lifting executive assembly 4 includes the header lifting actuator 4-2, and realizes the horizontal and vertical adjustment of the height of the header 2 through the hydraulic system 10, and the hydraulic system 10 includes Oil tank (10-1), filter (10-2), hydraulic pump (10-3), overflow valve (10-4), check valve (10-5), first electromagnetic reversing valve (10- 6), the second electromagnetic reversing valve (10-7), the hydraulic control check valve (10-8), the third electromagnetic reversing valve (10-9) and the throttle valve (10-10). The extension end of the header lifting actuator 4 - 2 is rotatably connected to the bottom of the header 2 , and the installation end of the header lifting actuator 4 - 2 is rotatably connected to the chassis 6 . When the header 2 of the harvester needs to be transported, the electromagnetic reversing valve 1 (10-6) is in the right working position, and the high-pressure oil enters the rodless cavity of the lifting ...

Abstract

The invention belongs to a header profiling device, a control system and method thereof and a harvester, and belongs to the field of agricultural machinery. The header profiling device comprises a profiling detection assembly, a header profiling adjustment assembly, a header lifting execution assembly, a header chassis hinge assembly and the control system. The profiling detection assembly is mounted in front of a header; the header profiling adjustment assembly is mounted at the front part of the header; the header lifting execution assembly is mounted between the header and a chassis; and the header chassis hinge assembly is arranged between the header and the chassis. Header position control in a transportation state and a header profiling harvesting operation state is realized throughthe header profiling adjustment assembly and the header lifting execution assembly; and the distance between a cutter and a ridge surface is detected by the control system for the profiling detectionassembly, the influence of the system profiling information lead amount is solved through a mathematical model, then the header profiling adjustment assembly is controlled to conduct transverse and longitudinal adjustment on the header so as to ensure that a certain distance can be kept between the cutter and the ridge surface, and the leaf vegetable harvesting loss and the cutter entering-soil damage caused by improper height adjustment of the cutter are reduced.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a header profiling device, its control system and method, and a harvester. Background technique [0002] Leafy vegetable harvesting is one of the most labor-intensive links in leafy vegetable production, and its labor intensity accounts for about 35% of the entire production process. It is also the last link to ensure the appearance and quality of harvested leafy vegetables. Leafy vegetables can be divided into sowing and row sowing according to their sowing methods. According to planting experience and related research, the yield of row sowing will not decrease or even surpass that of sowing in the same sowing area, and row sowing leaf vegetables are more suitable for mechanization. Harvested in an orderly manner and its appearance and regularity are higher than those harvested in disorder. At the same time, due to the low precision of ridge preparation before ...
