Combined peanut harvesting machine

Abstract

The invention discloses a combined peanut harvesting machine. The combined peanut harvesting machine comprises a machine frame; a walking mechanism is arranged at the bottom of the machine frame; a harvesting mechanism, a peanut picking mechanism, a cleaning mechanism, a conveying mechanism and a collecting mechanism are arranged on the machine frame in sequence; a dropping peanut recollecting mechanism is also arranged on the machine frame; the dropping peanut recollecting mechanism comprises a soil excavating assembly, a soil and peanut conveying assembly and a soil and peanut separating assembly; the soil excavating assembly is arranged on the rear side of the harvesting mechanism and is used for excavating surface soil which is subjected to harvesting through the harvesting mechanism; the soil and peanut conveying assembly is arranged on the rear side of the soil excavating assembly; an input end of the soil and peanut conveying assembly is used for receiving the surface soil which is excavated through the soil excavating assembly; the soil and peanut separating assembly comprises an input channel, a separating screen mesh and a peanut outlet channel; the input channel is connected with an output end of the soil and peanut conveying assembly and the separating screen mesh; the peanut outlet channel is communicated with the separating screen mesh and the cleaning mechanism. According to the combined peanut harvesting machine provided by the invention, automatic high-efficiency picking of dropping peanuts is realized.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a peanut combine harvester. Background technique [0002] Peanut is one of the main economic activities in our country. Most of the peanuts planted on a large scale are harvested by large-scale peanut combine harvesters, which have high harvesting efficiency and low economic cost. Most of the peanut harvesting in the prior art includes a frame, which is provided with a walking mechanism, a harvesting mechanism, a fruit picking mechanism, a cleaning mechanism, a conveying mechanism and a collecting mechanism. The mechanism, the cleaning mechanism, the conveying mechanism and the collection mechanism complete steps such as harvesting and collection of peanuts. [0003] The disadvantage of the prior art is that factors such as pests, over-harvest period, and rainwater immersion all lead to fruit drop, and the fruit that falls on the ground is difficult to be automatically harvested by the ...

Problems solved by technology

[0003] The disadvantage of the prior art is that factors such as pests, over-harvest period, and rainwater immersion all lead to fruit drop, and the fruit that falls on the ground is difficult to be automatically harvested by the harvesting mechanism. In the prior art, the loss can only be reduced by manual picking, and the The efficiency of manual picking is too low, and the existing technology lacks an effective high-efficiency technology for harvesting fallen fruit
