Technical Field
[0001] The utility model relates to an agricultural machine, in particular to a deep tiller which can efficiently utilize water and fertilizer in thin, hard and black soil areas. Background Art
[0002] In the black soil belt of Northeast China, due to the continuous use of chemical fertilizers and the abandonment of farmyard manure, the soil organic matter cannot be reasonably supplemented, and the soil organic matter content decreases year by year. In the Songnen Plain, the black soil layer of many plots has become thinner, and the soil water storage function has decreased. When it rains, runoff is formed, and soil erosion is serious, forming the so-called "thin, thin and hard" plots. If effective measures are not taken and the vicious cycle continues, the black soil layer will disappear. In order to solve the above problems, the utility model provides a deep loosening machine for efficient utilization of water and fertilizer in thin, thin and hard black soil areas. According to the characteristics of the "thin, thin and hard" plots, we adopt the method of returning the straw to the fields in full, so that the straw can be returned to the fields in full to supplement the soil organic matter. On the machine, a deep loosening machine for efficient utilization of water and fertilizer in thin, thin and hard black soil areas is used to break the plow bottom layer to connect the upper and lower water, set a rat path component, form a rat path after deep loosening, form a small reservoir under the tillage layer, activate the soil layer, return the straw to the fields in full, and gradually restore the soil organic matter, which solves the above problems well.

It is characterized in that the frame is composed of a fixed section of the main beam of the frame and a moving section of the main beam of the frame, and the relative position of the fixed section of the main beam of the frame and the moving section of the main beam of the frame is adjusted by the telescopic adjustment of the hydraulic cylinder installed thereon, that is, to adjust the working ridge distance of the machine, and the range of adjusting the ridge distance is between 55cm and 67cm, which is convenient for the operation requirements of different ridge distances among farmers.
[0005] It is further described that a grass cutting disc is provided directly above the front of the deep tillage shovel. The grass cutting disc is installed obliquely, and the grass cutting force of the grass cutting disc is adjusted by adjusting the compression force of the adjustment spring. The grass cutting disc cuts off the straw in front of the deep tillage shovel, so that the deep tillage shovel can operate smoothly in the straw-covered plot without dragging piles.
[0006] The deep tillage shovel further has a rat path component, which forms a rat path during the deep tillage process, is conducive to the infiltration of rainwater, forms a small underground reservoir, improves soil moisture content, and activates the soil layer.
[0007] It is further described that a pair of pressing wheels are arranged at the rear of the deep tillage shovel and the fertilizer pipe. The pressing wheels are arranged in a V shape. The deep tillage ditch produced by the deep tillage shovel is rolled to prevent moisture from running away after deep tillage. BRIEF DESCRIPTION OF THE DRAWINGS
