Description

Combined Subsoiler

technical field

The utility model relates to a combined subsoiling cultivator.

Background technique

At present, in agricultural cultivation, soil subsoiling, intertillage weeding, and fertilization are effective means to change the growth of crops. Soil subsoiling refers to the use of subsoilers to loosen the plow bottom layer below the plow layer 5 to 15 cm, loosen the soil and Deepen the thickness of the loose soil layer; subsoiling is one of the important techniques of conservation tillage. Due to long-term plowing or stubble removal operations, the bottom of the plowed soil rises and the cultivated layer becomes shallower, resulting in increased soil erosion and gradual soil degradation. The yield of crops is severely reduced, and the income of farmers is also reduced; intertillage and weeding can loosen topsoil, increase soil aeration, increase ground temperature, promote aerobic microbial activities and nutrient effectiveness, remove weeds, promote root extension, adjust soil moisture, reduce Weeds absorb nutrients in the surface soil and increase the utilization rate of nutrients for crops; fertilization is to increase the nutrients in the soil layer and increase crop yield.

The use of soil intertillage deep loosening technology can break the hard plow bottom layer, improve the quality of soil compaction, and then deepen the tillage layer; it can not only change the physical properties of the soil, but also change the chemical properties of the soil; it can also improve the lodging resistance of crops; it can improve Soil water storage and moisture retention capacity; intertillage and weeding can loosen topsoil, increase soil aeration, increase ground temperature, promote aerobic microbial activities and nutrient effectiveness, remove weeds, promote root extension, adjust soil moisture status, and reduce weeds’ impact on nutrients in the soil Absorption, so as to improve the utilization rate of crops to surface soil nutrients, reduce unnecessary waste, and increase crop yield; fertilization can provide crops with different nutrients needed to promote their growth and development during the growth and development process, so The required amount is different. Nitrogen, phosphorus, and potassium are a large number of elements needed by plants. In addition, iron, calcium, magnesium, sulfur, boron, etc. are also necessary for plant growth. However, the nutrient elements in the plant growth environment often cannot meet its needs, especially the large amount of nitrogen, phosphorus and potassium required by crops. Therefore, it is necessary to supplement the nutrient elements of plants through additional fertilization to improve the high yield and high yield of crops.

At present, when the existing subsoiler works on soil subsoiling, the traction resistance of the subsoiler increases sharply with the increase of the subsoiling depth. At present, the four-row subsoiling needs medium and high-power tractors to realize it, which increases the The cost of subsoiling and fuel consumption, and the large volume of high-power tractors make it difficult to turn the ground and reduce the operating speed.

Most of the existing subsoilers, intertillage weeders, and fertilizers are separated. To complete these processes, the machines need to go into the ground many times, so that the surface soil will be rolled and compacted many times, which will cause the surface soil to harden and hinder the growth of crops. The growth of the crops has a great impact; and the machine tools increase the manpower and material resources repeatedly, which greatly increases the cost; the nutrients required by different growth periods of the crops are different, and fertilization at the same location will cause unnecessary waste of fertilizers, or even Burning seedlings affects the normal growth of crops and is accompanied by waste of fertilizers.

At present, there are combined operating machines with two or more functions integrated into one, but the working performance is relatively poor when working, and the effect of working alone cannot be achieved, and there is no automatic protection and recovery function, which brings secondary inconvenience to the work. There is no simple adjustable function for layered fertilization; some machines have adopted spring protection function, but the required strength is large during work, which has caused a great increase in production and processing costs, and the replacement of parts is also more cumbersome; the fertilization sprocket drive adopts a single Driven by side sprockets, it is easy to cause uneven fertilization.
