Crop straw swather

Abstract

The invention belongs to the field of agricultural machinery, in particular to a crop straw swather. According to the crop straw swather, a panel is connected between an upper frame and a lower frame of a vertical face of a triangular pyramid rack, an upper right chain wheel and a lower right chain wheel are installed at the right ends of the two frames in a connecting mode, bearing pedestals are installed at the left ends of the two frames in a connecting mode, a vertical shaft penetrates through the position between the pedestals, and a lower chain wheel is installed at the lower end of the shaft in a connecting mode. An upper left chain wheel, an upper right chain wheel, an upper straw prodding rod disk and a lower straw prodding rod disk are installed on the vertical shaft from top to bottom respectively in a connecting mode, and a double-lug chain is connected between the left chain wheel and the right chain wheel of each group, and vertical straw supporting plates are installed on the double-lug chains at intervals in a connecting mode. The lower portions of two vertical frames on the other face of the rack are respectively arranged in a V-shaped slide rail in a sleeved mode. A hydraulic oil cylinder is installed between a horizontal frame and a beam in a connecting mode, wherein the horizontal frame is arranged between the two vertical frames, and the beam is arranged between the two slide rails. A speed reducer is erected on a horizontal support between the two vertical faces, and the lower end of a shaft of the speed reducer is connected with an upper chain wheel and a lower chain wheel which are coaxial. Straw cutting disks are arranged on the lower portion of the inner wall of the panel at intervals in a connecting mode. The upper chain wheel and the lower chain wheel which are coaxial are connected with the lower chain wheels and the straw cutting disks through chains respectively. The crop straw swather can cut straw smoothly, the straw is laid orderly, and the work efficiency is promoted obviously.

Description

technical field [0001] The crop straw windrowing machine of the invention belongs to the field of agricultural machinery. Background technique [0002] The windrowing of high-stalk crops such as corn, sorghum and sunflower is one of the most labor-intensive agricultural tasks. There are several types of small corn windrowing machines used today, such as the harvesting straw returning type and the vertical forward hanging type. There are straw conveying Unsmooth, scattered laying, manual finishing is still required, which increases the cost of harvesting. In addition, the machine cannot work in small fields in farmland and forest belts. Contents of the invention [0003] The object of the present invention is to provide a crop stalk windrowing machine with smooth cutting, neat laying of cut stalks, high work efficiency and flexible operation. [0004] The object of the present invention is achieved in that the crop stalk windrowing machine is composed of a frame, a hydraul...
