Double-floating front-drive gripping conveying mechanism

Abstract

The invention relates to a double-floating front-drive clamping and conveying mechanism, which includes a clamping frame, a clamping device installed on it and a power transmission system, and is characterized in that the clamping device includes two clamping devices mounted on the clamping frame. Group clamping chain The two groups of clamping chains have different lengths. One side of the clamping frame is provided with a tensioning wheel, which adjusts the tightness of the clamping chain. The other side of the clamping frame is provided with a support rod and a set The spring on the support rod, the end of the support rod is provided with a chain adjustment plate, and the double floating adjustment is carried out by the support rod and the spring. The driving sprocket is located at the front end of the clamping frame, connected with the power input mechanism through the transmission mechanism, The holding frame is provided with a clamping sprocket. The clamping chain of the present invention adopts a double-floating adjustment method, which has a large adjustment range and can effectively prevent the congestion of peanut vines; the driving device of the clamping chain is placed at the front end, which can not only save energy and reduce consumption, but also make the movement stable; The clamping chain adopts the combination of long and short chains to make seedling rowing smoother.

Description

technical field [0001] The invention relates to a clamping and conveying mechanism of a peanut combine harvester, in particular to a double-floating precursor clamping and conveying mechanism of a peanut harvester. Background technique [0002] In the existing peanut combine harvesting machines in my country, especially the semi-feeding peanut combine harvesters, the clamping chain of the clamping conveying mechanism generally adopts the adjustment method of one end fixed and one end floating to prevent the congestion of peanut vines, but the effect is not ideal. , When the amount of peanut vines entering the clamping and conveying mechanism is too large, congestion is likely to occur, which hinders the continued operation of the peanut combine harvester; the driving device is generally rear, and the movement stability is poor; at the same time, the length of the left and right clamping chains The same, poor seedling rowing. SUMMARY OF THE INVENTION [0003] The present inv...
