Description

Ridge field straw comprehensive pulverizer

technical field

The utility model relates to a comprehensive straw pulverizer used on ridge farming, in particular to a comprehensive straw pulverizer for ridge farming used for realizing no-tillage ridge planting, and belongs to the technical field of agricultural machinery.

Background technique

In recent years, my country has actively promoted mechanized conservation tillage technology. Ridge farming is the main farming feature in the cold and sandy regions of Northeast China. At present, there are problems such as serious straw blockage and difficult ridge shape restoration in the process of combining ridge farming and conservation tillage technology.

In Northeast my country, in order to increase the ground temperature when planting in spring, and to drain waterlogging smoothly in the rainy summer season, ridge farming is the main farming method in Northeast China. In order to reduce power consumption, the traditional ridge farming straw grinder can only grind straws above the height of the ridge table. The straw is crushed, and a large amount of straw is piled up in the furrow and cannot be crushed. As a result, the soil in the furrow cannot be repaired to the ridge platform to cover the chemical fertilizer due to the obstruction of the straw during intertillage and topdressing, or the ridge platform is repaired during the intertillage topdressing. The stalks in the furrows are too long, and the stalks will push down the seedlings, resulting in reduced production. In order to solve this problem, the traditional ridge farming method uses a rotary tiller to fully rotate the surface of the ground or use a plow to turn the land before sowing in spring. However, the use of rotary tillers or conventional plows causes serious waste of power, severe soil moisture loss, and increased operating costs, which are in contradiction with conservation tillage techniques. Therefore, it is necessary to adapt to conservation tillage techniques The comprehensive crushing equipment for straw in ridge-growing areas ensures the smooth promotion of conservation tillage technology in ridge-growing areas in Northeast my country and realizes the sustainable development of agriculture in ridge-growing areas.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further by embodiment.

In Figure 1 and Figure 2: 1 is the movement track of the stubble cutting blade, 2 is the protective plate, 3 is the gearbox, 4 is the traction frame, 5 is the power shaft, 6 is the beam I, 7 is the consolidation device I, and 8 is the beam II , 9 is the consolidation device II, 10 is the straw shovel, 11 is the beam III, 12 is the consolidation device III, 13 is the side plate, 14 is the depth-limiting wheel, 15 is the chain, 16 is the power output shaft, and 17 is the stubble blade , 18 is a blade consolidation device, and 19 is a chain box.

Fig. 1 and Fig. 2 show an embodiment of the comprehensive pulverizer for straws in this ridge cropping field. As can be seen from the figure, three straw shovels 10 are arranged in the present embodiment, and they are arranged with an inclination backward, fixed on the crossbeam II 8, and the straw shovels 10 Go deep between the stubble removal blades 17, the transverse gap between the straw shovel 10 and the stubble removal blade 17 is very small, about 7-10mm, and pass through the stubble removal blade 17 to go deep into the oblique front and bottom (adjustable), the vertical distance between the end of the straw shovel 10 and the stubble removal blade 17 The distance is about 7-10cm, and the horizontal distance from the front of the power output cutter shaft is about 8-12cm.
