Problems solved by technology

The sorghum harvesters in use are almost all converted from wheat or rice harvesters, and the harvesting effect is not ideal
The reason is that the transportation of tall and thick stalk crops after harvest cannot be effectively guaranteed by traditional mechanisms
[0004] The search found that the Chinese utility model patent with the application number of 98242245.8 discloses a reed harvester. The grain-holding device needs to change the movement direction of the grain-holding teeth at the moment of starting and ending the grain-holding, resulting in a huge acceleration , causing great alternating stress, easy to damage the components, resulting in poor reliability, and the machine adopts the traditional pa...

Embodiment 1

[0021] The basic structure of the harvester for tall and thick stalk crops in this embodiment is as follows: figure 1 As shown, it comprises a shaving-type horizontal cutting device 14 positioned at the front and lower part of the walking machinery frame, a group of horizontally arranged toothed conveyor belt lower reeling devices 15 positioned on the cutting device 14, and two horizontal reeling devices up and down by the lower reeling device 15. The horizontal forced clamping conveying device 13 formed around the conveying chain, the conveyor chain type longitudinal forced clamping conveying device 16 located on one side of the lateral forced clamping conveying device 13, and the straw collection box 17 located at the rear end of the longitudinal forced clamping conveying device 16 , also includes the upper reeling device 12 positioned above the lower reeling device, the uppermost part in the figure is the chassis 11.

[0022] The concrete structure of upper reeling device 1...

Abstract

The invention relates to a high and thick-stalk crop harvester belonging to the technical field of agricultural machinery. The high and thick-stalk crop harvester comprises cutting apparatuses, a lower crop poking apparatus, a transverse forced clamping and conveying device, a conveyer chain type longitudinal forced clamping and conveying device and a stalk collecting box. The high and thick-stalk crop harvester further comprises an upper crop poking device positioned above the lower crop poking device, wherein the upper crop poking device comprises a crop poking shaft, two ends of the crop poking shaft are respectively fixedly connected with a center plate, horizontal crop poking rods are hinged between the two center plates, radially extending scrabbling teeth are distributed on the crop poking rods at intervals, eccentric center plates are movably sleeved on the crop poking shaft, the peripheries of the eccentric center plates are hinged with one ends of crank throws, corresponding to the crop poking rods, and the other ends of the crank throws are connected with the end of an adjacent crop poking rod in angular positions that the scrabbling teeth always face downwards. According to the high and thick-stalk crop harvester, the alternating stress is avoided, and the harvester can reliably and stably work for a long time.

Description

technical field [0001] The invention relates to a harvesting machine, in particular to a harvester for tall and thick stalk crops, which belongs to the technical field of agricultural machinery. Background technique [0002] In order to realize the effective utilization of crop stalks, its effective harvesting is the first step. At present, the harvesting technology for crops with short and thin stalks (such as rice, wheat, and forage grass, etc.) has become mature and perfect, and has formed standard and stereotyped products, while for crops with tall and thick stalks (lucid bamboo, tall reed , ramie, sorghum, etc.) research on mechanized harvesting is relatively lagging behind. [0003] According to the applicant's understanding, the mechanized harvesting of ramie at home and abroad mainly focuses on the research of mechanized peeling technology, and the harvester basically belongs to the blank. The sorghum harvesters in use are almost all converted from wheat or rice ha...
