Farming device that loosens soil
Technical Field
The invention relates to the technical field of farming machinery, in particular to an agricultural planting soil loosening device.
Background
In agricultural production, soil cultivation is an essential step, but different crops have different requirements on the soil cultivation depth, root crops require a soil layer depth of 75cm generally and a critical value of 50cm-75 cm; for grain crops, 50cm may be considered optimal, with 25cm-50cm being the threshold. Among crops, the roots of cotton, sorghum, corn and the like are deep, and farmers need to loosen soil deeply when cultivating soil; the root systems of rice, millet, sweet potato, peanut and the like are shallow, so that the soil does not need to be cultivated deeply, but the existing soil loosening device does not have the function of adjusting the cultivation depth of the harrow teeth and mainly depends on the self experience of farmers for operation; however, with the development of agricultural mechanization, more and more agricultural activities are completely operated by machines, and the depth of the loosened soil cannot be adjusted according to the growth habits of different crops without the soil loosening device for adjusting the tilling depth, which is not beneficial to the growth of the crops.

Detailed Description
In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Example (b): as shown in fig. 1-3, an agricultural planting soil loosening device comprises a positioning portion 1 and a plurality of rake teeth 2, wherein the positioning portion 1 comprises a fixing member 3, a limiting member 4 and a connecting member 5, the connecting member 5 is installed at the center of the top of the fixing member 3, the two ends of the fixing member 3 are fixedly connected with the limiting member 4, the limiting member 4 is provided with a plurality of adjusting bolts 6, the outer parts of the adjusting bolts 6 are respectively provided with a through hole 7, an adjusting member 8 installed on the rake teeth 2 penetrates through the through hole 7 to be in threaded connection with the adjusting bolts 6, the adjusting member 8 is formed by combining an adjusting nut 9 and a connecting bearing 10, the diameter of the connecting bearing 10 is larger than that of the adjusting nut 9, the bottom of the connecting bearing 10 and the rake teeth 2 are integrally formed, the rake teeth 2 are divided into an adjusting portion 11 at the top and a soil loosening portion 12 at the bottom, the adjusting portion 11 at the top is of a hollow structure, a cavity 13 is arranged in the inner part, and the soil loosening portion 12 at the bottom is of a solid structure, the bottom of the utility model is in a taper shape.
The adjusting bolt 6 is arranged at the central position of the through hole 7, the diameter of the through hole 7 is larger than that of the adjusting part 8, the through hole 7 is matched with an adjusting part 11 arranged at the upper part of the rake teeth 2, and two ends of the adjusting bolt 6 are fixedly arranged at the lower part of the fixing part 3 and the upper part of the limiting part 4 respectively.
The rake teeth 2 are of a conical structure which is narrower from top to bottom, so that the soil loosening is more convenient; the diameter of cavity 13 bottom is greater than adjusting bolt 6's diameter and is less than the diameter of through-hole 7 for rake teeth 2 is when adjusting the depth of loosening the soil, can be at most with cavity 13 complete rising to the top of locating part 4, and the regulation dynamics is big, can adapt to the demand of loosening the soil of multiple crops.
The length of cavity 13 is more than or equal to the length of adjusting bolt 6 for rake teeth 2 can freely move up and down on adjusting bolt 6 through adjusting part 8, is convenient for adjust the depth of loosening the soil of rake teeth 2.
The adjusting nut 9, the connecting bearing 10 and the rake teeth 2 are of an integrally formed structure, so that the connecting strength between the adjusting nut, the connecting bearing and the rake teeth is higher.
The adjusting bolts 6, the through holes 7, the rake teeth 2 and the adjusting pieces 8 are in uniform numbers so as to be arranged in one-to-one correspondence with each other.
The positioning part 1 and the rake teeth 2 are made of hard metal materials, so that the intensity is high, and the development of land cultivation work is facilitated.
The working principle is as follows: the invention relates to an agricultural planting soil loosening device, which comprises the following steps:
firstly, judging the type of crops planted in the land to be cultivated, and obtaining the information of the scarification depth; then, according to the information, the length of the rake teeth 2 exposed out of the limiting piece 4 is adjusted; during adjustment, an adjusting part 8 arranged at the upper part of the rake teeth 2 penetrates through a through hole 7 formed in the limiting part 4 and is in threaded connection with an adjusting bolt 6 into a whole, and the adjusting part 8 is screwed up or down as required, so that the purpose of adjusting the length of the rake teeth 2 exposed out of the limiting part 4 is achieved; finally, after the loose soil length of the harrow teeth 2 is adjusted, the device is arranged on an agricultural machine through a connecting piece 5 for cultivating the soil.
