Abstract

The invention provides a land leveler and a scarifier thereof. The scarifier comprises a tooth frame, scarifying teeth and a fastening device, wherein the scarifying teeth are movably arranged on the tooth frame along the axial direction and are fixed by the fastening device. The scarifier can automatically adjust arrangement positions of the scarifying teeth according to the requirement of an actual working condition, and the number of scarifying teeth can be increased or decreased within a total width range of the tooth frame; the scarifier is particularly suitable for some special working conditions; and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a grader and a ripper thereof. Background technique [0002] At present, all rippers on the market use a fixed number of teeth and a fixed tooth position, such as figure 1 As shown, the ripper in the picture has 5 large teeth and 9 small teeth. Once produced, the tooth position is fixed and cannot be adjusted. The number of teeth can only be reduced by removing the large and small teeth on the current tooth position. According to the prior art, there are following defects: [0003] 1. The specificity of the working conditions is not strong, the loosening area and the position of the loosening tank have been restricted and cannot be adjusted; [0004] 2. The operating efficiency is low, and some areas that need to loosen the soil (such as the slender belt to be loosened) require multiple operations to meet the loosening requirements due to the limitation of the loosening ran...
