Cole crop pulling and taking jaw assembly

The invention provides a cole crop pulling and taking jaw assembly, and belongs to agricultural machinery. Upper swing arms are symmetrically hinged to the upper side portion of a two-way hydraulic cylinder, lower swing arms are symmetrically hinged to the portions, located below the upper swing arms, on the lower side portion of the two-way hydraulic cylinder, jaw teeth are symmetrically hinged to the upper swing arms which are symmetrically arranged in a hinged mode and the lower swing arms which are symmetrically arranged in a hinged mode, an arm base is arranged on the lower end portion of a cylinder rod of the two-way hydraulic cylinder, and drive arms are symmetrically hinged to the portions between the lower swing arms which are symmetrically arranged in the hinged mode and the arm base respectively. According to the assembly, selective clamping, pulling and harvesting of cole crops are achieved, and the cole crop pulling and taking jaw assembly has the advantages of being simple in structure, convenient and reliable in clamping and pulling operation, good in harvest quality, high in selectivity, wide in application range and beneficial to the improvement of agricultural economic benefits.
