Double-chain type ditcher for sowing seeds in corn experimental field

Abstract

The invention relates to the technical field of corn planting and particularly relates to a double-chain type ditcher for sowing seeds in a corn experimental field. The double-chain type ditcher comprises cross beams, wherein first bearing seats and second bearing seats are respectively arranged at the two ends of the cross beams; power shafts are arranged between the first bearing seats, and driving wheels are arranged on the power shafts in the first bearing seats; driven wheels are arranged at the inner sides of the second bearing seats; a chain is arranged between the driven wheel and thedriving wheel on the same cross beam; a plurality of toothed plates are uniformly distributed on the outer side surfaces of the chains; the two ends of the power shafts, positioned at the outer sidesof the first bearing seats, are respectively provided with first bearing frames; one end of each power shaft, positioned at the outer side of each first bearing frame, is provided with a second bearing frame; the outer side of each bearing frame, close to one end of a first connecting rod, is provided with a positioning pin; a positioning lug is arranged under one vertical end of the second bearing frame; a hydraulic telescopic rod is connected between the positioning lug and the positioning pin. The double-chain type ditcher has the beneficial effects that the ditching efficiency in corn planting can be improved, the ditching cost also can be reduced, and the whole ditcher is convenient in installation and use.

Description

Technical field: [0001] The invention relates to the technical field of corn planting, in particular to a double-chain trencher used for sowing corn experimental fields. Background technique: [0002] my country is a large agricultural country with a wide range of arable land and a suitable climate for corn planting. Combined with the advancement of science and technology and the development of productivity, machinery is widely used in the process of corn planting, and the use of machinery improves the efficiency of corn planting and reduces the physical strength of growers. labor. Among them, in the process of corn planting that needs to be ditched, the traditional ditching method is mainly carried out manually or by large-scale machinery, but manual ditching has the disadvantages of slow opening efficiency and laboriousness, and large-scale mechanical ditching will increase the cost of opening. It is not conducive to improving economic efficiency. For this reason, we have...
