Hook type peanut harvester

Abstract

A hook type peanut harvester comprises a machine frame. Walking wheels are arranged on the lower side of the rear portion of the machine frame. A traction suspension and a power speed regulation mechanism are arranged at the upper portion of the front end of the machine frame. A scraper knife low in the front and high in the back is arranged at the lower portion of the front end of the machine frame. A roller shutter conveying chain ladder low in the front and high in the back is arranged on the machine frame. Arc-shaped hook rods for hooking peanut seedlings are evenly arranged on the roller shutter conveying chain ladder and connected with the power speed regulation mechanism in a transmission mode. A set of seedling straightening rods arranged in the front and back direction are arranged between the edge of the front side of the roller shutter conveying chain ladder and the edge of the rear side of the scraper knife and are high in the front and low in the back. The hook type peanut harvester is reasonable in design, simple in structure and convenient to use; particularly due to the design of the roller shutter conveying chain ladder, it is ensured that peanut seedling fruits and soil are prevented from being accumulated in front of the harvester when the harvester works in a sandy land and a semi-sandy land, it is ensured that harvesting work is conducted smoothly, energy consumption is lowered, harvesting efficiency is improved, harvesting cost is saved, practicability is high, and application and popularization are easy.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a hook-type peanut harvester. Background technique [0002] The existing peanut harvesting machinery can be divided into three categories according to the principle of harvesting peanuts. One category is clamping harvesting machinery mainly used in sandy and semi-sandy soils. The clamping device clamps the peanut seedlings, and there is a spatula below to cut off the peanut roots. The clamping device is driven by the power to the rear and upper part of the machine, and the peanut seedlings are transported to the rear of the machine and laid on the ground. , to complete the harvesting operation. [0003] The other is a harvesting machine that utilizes the working principle of the roller-shutter conveyor chain ladder. When the machine is working, the power drives the harvester to move forward. At the same time, the shovel of the machine goes into the soil to a certa...
