Combined deep loosen cultivator

Abstract

The invention relates to a combined deep loosen cultivator, characterized in that a rack is provided with a draft gear, a fertilizer apparatus, a deep scarification device, a depth-controlled device, a cultivating device. Compared with the prior art, according to different fertilizer requirements in different periods of different crops, a dual-adjusting system is used for fertilization adjustment. A double-end dividing funnel is used on the upper part, on the middle part, an inverted Y-shaped flow divider is used to apply fertilizer to the double-end dividing funnel in divided weight, and a three-layer fertilizer apparatus is used for a fertilizer pipe on the lower part. Space size of the three-layer fertilizer apparatus can be adjusted through adjusting the angle of a layering adjusting plate. Thus, fertilizer of each layer can be adjusted again, realizing fertilization in more accurate quantity and fertilization in a layering manner as needed. The height of the fertilizer pipe can be adjusted according to different crop roots and different deep loosen cultivation depths. Sprocket drive is used for fertilization drive, so uniform fertilization can be realized in different operation bases.

Description

technical field [0001] The invention relates to a combined subsoiler. Background technique [0002] 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, adju...

Problems solved by technology

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.

[0004] 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 Subsoiling costs and fuel consumption, and because of the large volume of high-power tractors, it is difficult to turn the ground and reduce the operating rate

[0005] Most of the existing subsoilers, intertillage weeding machines, and fertilizer applicators 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, and even Burning seedlings affects the normal growth of crops and is accompanied by waste of fertilizer

[0006] 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, resulting in greatly increased production and processing costs, and the replacement of parts is also more cumbersome; the fertilization sprocket drive adopts a single Side sprocket drive, easy to cause uneven fertilization
