Background technique

At present, in recent years, most of the land preparation in my country has adopted rotary tillage soil preparation machines year after year. However, the existing rotary tillage machines have insufficient soil preparation depth. In addition, a large amount of chemical fertilizers are currently used in farmland, which has caused the problems of shallow plow layer, thick plow bottom layer and soil compaction in my country. It is very serious, resulting in the decline of soil organic matter content, the reduction of water storage and moisture conservation capacity, and the unreasonable structure of soil plow layer, which seriously affects agricultural production. The cultivated land soil in our province also has problems such as severe stress resistance and buffer performance, and degradation of soil plow layer quality. At present, mechanized subsoiling technology is promoted to improve soil conditions, but the application of this technology is not effective. Therefore, in order to rationally loosen the soil, break the hard plow bottom layer, improve the physical properties of the soil, optimize the soil structure, and build a reasonable plow layer.

Each of the soil crushing devices A small gearbox is respectively connected to each crushing shaft, and each of the small gearboxes is respectively connected to a driving transmission, and one end of the crushing roller is connected to a driving transmission through a side gearbox.

Further, the soil crushing device is composed of a plurality of soil crushing shafts and soil crushing blades, and the soil crushing blades are arranged symmetrically in a double helix, and are evenly arranged along the circumference of the soil crushing shaft to form a spindle-shaped structure.

Further, the crushing shaft is provided with a plurality of installation and adjustment holes.

Further, the drive transmission device includes a large gearbox, a transmission shaft, a chain drive and a connecting sleeve. The output shaft of the large gearbox is connected to the transmission shaft installed on the frame, and one end of the transmission shaft is connected to the side gearbox. The two small gearboxes of the soil device are connected to a connecting sleeve, and the transmission shaft and each connecting sleeve are respectively connected through a chain drive. The chain drive is respectively provided with sprockets on the transmission shaft and each connecting sleeve, and the connection chain composition.

Beneficial effects of the present invention:

1. The application of the present invention can increase soil pores, effectively adjust the ratio of three phases (solid phase, gas phase, and liquid phase), increase temperature and prevent cold, slow down soil erosion and wind erosion, enhance soil recovery ability, reduce disaster losses, and promote sustainable agricultural development , to ensure that agricultural production increases and farmers' income increases.

2. Through the application of the present invention, cost saving and efficiency enhancement can be achieved, soil properties can be improved, soil fertility can be cultivated, and the ability of agricultural disaster prevention and mitigation can be improved. On the premise of meeting the requirements of agronomy and soil science, the present invention actively carries out the research on supporting technologies of agricultural mechanization, broadens the field of agricultural mechanization research, opens up a new working mode, promotes the rational construction of soil plow layer, reduces the application of chemical fertilizers, and slows down the soil The compaction phenomenon occurs, the soil recovery ability is enhanced, and the healthy and sustainable development of agriculture is realized.

Detailed ways

The present invention will be described in further detail below in conjunction with accompanying drawings and examples.

Embodiment: as shown in Fig. 1, Fig. 2, the present invention comprises subsoiling shovel 9, soil breaking device 8, stubble breaking roller 3, ridging shovel 2, suppressing roller 1 that are arranged in turn on the frame according to the direction of travel. and the drive transmission set on the frame 7, each broken soil shaft 13 of the described soil breaking device 8 is connected with a small gearbox 6 respectively, and each small gearbox 6 is connected with the drive transmission respectively, and the broken stubble One end of the roller 3 is connected to a driving transmission device through a side gearbox 10 .

As shown in Figures 3 and 4, the crushing device is composed of a plurality of crushing shafts 13 and crushing blades 14, the crushing blades 14 are arranged symmetrically in a double helix, and are evenly arranged along the circumference of the crushing shaft 13 to form Spindle structure.

As shown in Figures 1 and 2, the drive transmission device includes a large gearbox 4, a transmission shaft 11, a chain drive 5 and a connecting sleeve 12, and the output shaft of the large gearbox 4 is connected to the transmission shaft installed on the frame 7 11. One end of the transmission shaft 11 is connected to the side gearbox 10, and the two small gearboxes 6 of the soil breaking device 8 are connected to a connecting sleeve 12, and the transmission shaft 11 and each connecting sleeve 12 are respectively connected by a chain transmission 5, The chain transmission 5 is formed by setting sprockets respectively on the transmission shaft 11 and each connecting sleeve 12, and connecting chains between them.

Described stubble roller 3 is existing device rotary tillage. The subsoiling shovel 9 is positioned at the front end of the implement, is installed on the bottom of the frame 7, and can be adjusted up and down through the mounting holes on it.
