According to the applicant's understanding, there are currently two methods of floating depth limit for multi-row harvesting platforms of the existing garlic combined harvesting equipment: one is single-row harvesting platforms floating independently, which is characterized by good ground profiling effect, but complex structure and single-row overload capacity. It is low and prone to failure; instead, it adopts the overall consistent up and down floating, which is characterized by a simple structure, but when the left and right directions are tilted, there is a large difference in the excavation depth between the left and right sides, which affects the harvesting quality
The Chinese patents with application numbers 2018111991152 and 2018116510712 respectively disclose two types of multi-row garlic combine harvesters, but the harvesting table of the former lacks the function of profiling the ground, so the digging depth is difficult to control, and it is easy to cause garlic digging damage; although the harvesting table of the latter Because there are depth-limiting wheels on both sides of the front end, it can float up and down, but when the walking chassis tilts left and right, the harvesting table cannot be kept horizontal, so the excavation damage will still be caused by the inconsistency of left and right harvesting digging depths

Embodiment 1
[0019] The harvesting platform of the present embodiment is installed in figure 1 Front end of a multi-row garlic combine harvester shown. The crawler-type walking chassis 9 of the combine harvester is equipped with garlic elevating soil clearing conveying device 10 and self-unloading fruit collection bin 11, and its front part is equipped with a harvesting platform that can float up and down through a harvesting platform mounting frame 1 that can rotate left and right. Frame 3 and the conveying bar chain device 2 where the garlic is collected and arranged side by side. The front end of the harvesting platform 3 is equipped with a plurality of single-path cutting units 5 supported on the depth-limiting wheels 4 on both sides. The conveying direction is equipped with clamping conveying chain, and the excavating shovel 6 that stretches forward is equipped with respectively below it, and the grain dividing device 7 and the grain holding device 8 are equipped with at the front end...

The invention relates to a harvesting platform of a garlic combine harvester, and belongs to the technical field of agricultural machinery. The harvesting platform comprises a harvesting platform mounting frame, wherein the harvesting platform mounting frame is supported at the front end of a harvester chassis through rotary oil cylinders on two sides. A horizontally-extending load bearing inner sleeve connected to the front power output end of the chassis is arranged on the rear lower portion of the harvesting platform mounting frame. A left auxiliary support device and a right auxiliary support device are respectively arranged on two sides of the rear middle portion of the harvesting platform mounting frame, and respectively form rotation pairs together with a left rotating track and a right rotating track at the front end of the chassis, wherein the rotation pairs rotate around the axis of the load bearing inner sleeve. The upper portion of the harvesting platform mounting frame ishinged to a harvesting rack through horizontal hitching shafts on both sides, and a seedling dividing device, a seedling holding device, an excavating shovel and a depth limiting wheel are mounted atthe front end of the harvesting rack. Two sides of the harvesting rack are supported on the harvesting platform mounting frame through lifting cylinders. The harvesting platform has the advantages that overall all-directional floating and overall left-right rotatory floating of the harvesting platform can be realized, so that the digging depth of the harvester is reasonably regulated to ensure theharvesting quality.
Description
technical field [0001] The invention relates to a harvester, in particular to a harvesting platform of a garlic combine harvester, which belongs to the technical field of agricultural machinery. Background technique [0002] Garlic is one of the important economic crops, and its harvesting process includes digging and laying, cutting seedlings, cutting roots, removing soil and cleaning, and collecting and bagging. According to the retrieval, the Chinese patent application number 2018102524014 discloses a typical garlic combine harvester. According to the applicant's understanding, there are currently two methods of floating depth limit for multi-row harvesting platforms of the existing garlic combined harvesting equipment: one is single-row harvesting platforms floating independently, which is characterized by good ground profiling effect, but complex structure and single-row overload capacity. It is low and prone to failure; instead, it adopts an overall consistent up and ...
