Combine harvesting machine

Abstract

The invention discloses a combine harvesting machine which comprises a clamping chain press block, a threshing roller, a grass discharge chain, a clamping delivering chain, a seedling dividing bar, stalk cutters, a seedling drawing star wheel, spike bending bars, a machine frame and a seedling holding mechanism; the seedling holding mechanism comprises a seedling holding finger, a seedling holding finger seat, an upper bending cover plate, a lower bending base plate, an annular chain, a driving chain wheel, a driven chain wheel, a left bending chain wheel and a right bending chain wheel. Meanwhile, the invention also provides a combine harvesting machine which can realize full feeding of spikes. In the invention, a seedling holding and spike bending mechanism is used on a semi-feeding combine harvesting machine, a conveying distance of harvest crops into the roller is shortened, spikes are introduced into the roller in order, a transmission chain of the combine harvesting machine is simplified, and the weight of the harvesting machine and the energy consumption of the whole machine are reduced; By the combine harvesting machine which can realize full feeding of the spikes, accurate crop spikes harvesting can be realized, the quantity of leaves and stalks introduced into the threshing roller is greatly reduced, the length of the transmission chain and the volume of the roller are shortened, and the energy consumption and the weight of the machine are reduced.

Description

technical field [0001] The invention relates to a combine harvester. Background technique [0002] In the prior art, a combine harvester includes a clamping chain briquetting block, a threshing drum, a grass discharge chain, a clamping conveying chain, a splitting stalk, a stalk cutter, a reeling star wheel, a crop guide plate, a guide plate, Rack and Fuhe mechanism. The grain-holding mechanism includes a roller chain (or a snap-finger reel), a grain-holding finger, a grain-holding finger seat, an upper cover plate and a lower bottom plate. The lower base plate is installed on the frame, the top of the lower base plate is equipped with a contraction limit shaft, the bottom of the upper cover plate is equipped with an extension limit block, and the upper cover plate is fastened on the lower base plate. The inner end of the upper cover plate and the lower bottom plate is provided with a limit plate for the holding finger seat, and the outer end is provided with a retractable...

Problems solved by technology

In this process, not only the distance is long, but also because of the many transmission chains, the structure is complex, the energy consumption is high, and the quality is heavy, which is not suitable for the situation in some areas of our country where the field area is small, the transportation is inconvenient, and the purchasing power is low.
