Embodiment Construction

[0018] figure 1 It is a field photo of the existing rotary tiller cultivating the purple soil slope farmland, figure 2 It is the rotary tiller of the existing rotary tiller. The rotary tiller generally has a shallower plowing depth, generally 12-14 cm. For the more compact soil such as purple soil, it generally needs to be plowed twice in order to meet the sowing conditions. Cultivation erosion is strong.

[0019] image 3 , Figure 4 , Figure 5 It is a front view, a side view and a front view of the cutter head of a rotary tiller for preventing and controlling slope farmland. The rotary tiller consists of a main knife 21, a left hollow knife 22, a right hollow knife 23, a rotating shaft 1, a fixed pile 3 and 11 mounting holes are formed. The whole rotary tiller is divided into two knife sets, and every three knife heads 2 form a knife set. During the installation process, the knife heads 2 are connected to the fixed pile 3 by threaded fasteners, and the rotary tiller i...

Abstract

The invention relates to the technical field of agricultural machinery and provides a rotary tillage knife capable of preventing and controlling slope farmland tillage erosion. The rotary tillage knife is composed of a main knife, a left-side hollow knife, a right-side hollow knife, a rotating shaft, a fixed pile and mounting holes, the left-side hollow knife and the right-side hollow knife are welded on the main knife, the main knife, the left-side hollow knife and the right-side hollow knife jointly form a complete knife head, the knife head is connected on the fixed pile by utilizing a threaded fastening member, the fixed pile is connected on the rotating shaft by means of welding, six knife tips are equidistantly arranged on the rotating shaft, and two mounting holes are formed in eachof two ends of the rotating shaft. The rotary tillage knife can reduce tillage erosion, increase tillage depth of purple soil slope farmland and enhance soil breaking effect and is conducive to improving soil quality and soil productivity when being used for a long time.

Description

technical field [0001] The invention relates to a rotary tiller for preventing and treating erosion of sloping cultivated land, belongs to the technical field of agricultural machinery, and is especially suitable for a rotary tiller for cultivating purple soil sloping cultivated land. Background technique [0002] The purple soil hilly area has shallow soil layer, poor corrosion resistance, loose structure and easy erosion. Usually, the shallow soil layer directly underlies the parent rock. Because these sloping cultivated lands have the characteristics of large slope, short slope length, and thin soil layer, and the cultivation intensity Large, intense tillage erosion caused severe soil loss on the upper slopes of the purple soil area, and the soil layer became shallower. In practice, the upper part of most purple soil slope cultivated land always maintains a soil layer thickness of 10-20 cm, which basically depends on the depth of cultivation. The rotary cultivator is an ...
