Description

Technical Field

[0001] This utility model relates to a peanut cultivation and hilling device, belonging to the field of agricultural machinery technology. Background Technology

[0002] Hilling and hoeing are crucial field management practices for peanut growth. They improve soil conditions, regulate water, fertilizer, air, and heat, increase soil aeration, improve root oxygenation, and ensure proper physiological pegging. Since peanuts must establish a large root system during flowering to produce fruit, high yields require hilling and ridge maintenance during cultivation. Peanut ridges are relatively wide (about 10 cm or more wider than other ridged crops), necessitating extensive hilling to protect the ridge surface and prevent empty pegging, thus increasing the fruiting rate.

[0003] There are many types of existing inter-row tillers and ridging machines, all suitable for crops such as potatoes, corn, cotton, tobacco, and sugarcane. There is no suitable inter-row tiller and ridging machine for peanuts. Existing ridging devices mostly use a pair of rotary or spiral ridging wheels, both arranged parallel to the furrow line. Examples include Chinese patent applications CN201711470147.7, "An Adjustable Inter-row Tiller and Ridging Machine," CN 201721122889.6, "Inter-row Tiller and Ridging Equipment," and CN202220545719.3, "A Compound Auger Inter-row Tiller and Ridging Device," etc. Because there is no angle between the ridging wheels and the furrow line, it is impossible to achieve a large amount of ridging on the peanut ridges. Soil on the ridge slope easily slides down the slope, resulting in insufficient ridging on the peanut ridge slopes. This affects the peanut's ability to peg during the flowering period, reducing the fruiting rate and causing a decrease in peanut yield. In addition, the height of the hilling wheel cannot be automatically adjusted according to the shape of the furrow and the amount of soil required. Utility Model Content

[0004] The purpose of this utility model is to provide a peanut cultivation and hilling device that increases the hilling height and soil volume during peanut cultivation management, ensuring that the peanut pegging reaches the soil during the flowering period, thereby improving the pegging rate and fruiting rate. The device automatically adjusts the hilling height of the hilling wheel according to the shape of the furrow and the required amount of soil, improving the efficiency and quality of hilling and ridge protection, and solving the aforementioned technical problems existing in the prior art.

[0005] The technical solution of this utility model is: a peanut inter-cultivation and hilling device, comprising a hilling device mounting base, a support arm, two hilling wheel mounting plates, and two hilling wheels. The hilling device mounting base is suspended at the rear of the frame. The lower part of the hilling device mounting base is hinged to the support arm via bolts. The front part of the support arm is provided with a fixing flange, and fixing seats are provided on both sides of the fixing flange. The two fixing seats are respectively hinged to the front end of the hilling wheel mounting plate via pins. The support arm is located between the two hilling wheel mounting plates. The rear part of the two hilling wheel mounting plates is provided with hilling wheels. The hilling wheels are arranged at an angle to the furrow line, and the two hilling wheels are inclined in opposite directions, arranged in a V-shape, with the opening facing backward. The upper part of the hilling device mounting base is hinged to the upper end of the shock absorber via an upper mounting shaft, and the lower end of the shock absorber is hinged to the upper part of the support arm via a lower mounting shaft. The height of the hilling wheels is automatically adjusted according to the shape of the furrow by the shock absorber spring inside the shock absorber.

[0006] Furthermore, the two hilling wheel mounting plates are connected to the support arm via their respective adjustment plates. One end of the adjustment plate is hinged to the hilling wheel mounting plate via an adjustment plate bolt, and the other end of the adjustment plate is provided with multiple position adjustment holes. After the position adjustment holes of the two hilling wheel mounting plates overlap, they are hinged to the support arm via an adjustment plate bolt. By changing the engagement of the adjustment plate bolt with different position adjustment holes, the distance between the hilling wheel mounting plate and the support arm is changed, thereby adjusting the inclination angle between the two hilling wheels and the furrow line.

[0007] Furthermore, the two hilling wheels are arranged symmetrically along the furrow line, and the inclination angles of the two hilling wheels with the furrow line are symmetrical and equal.

[0008] Furthermore, the soil-cultivating wheel mounting plate is provided with multiple soil-cultivating device mounting holes, and the soil-cultivating wheel shaft passes through one of the soil-cultivating device mounting holes and is fastened to the soil-cultivating wheel mounting plate by a positioning nut; the soil-cultivating wheel shaft is connected to the soil-cultivating wheel through the soil-cultivating wheel bearing seat and the inner bearing.

[0009] Furthermore, the soil-laying wheel has multiple curved strips on its circumference, all of which are curved in the direction of the soil-laying wheel's movement, resembling a whirlwind.

[0010] This utility model relates to tillage plows and shock absorbers, which are all technologies known and used in the field. The inclined hilling wheel increases the soil breaking rate and the amount of soil hilled on the ridge, ensuring that all the pegging is in the soil when the peanut flowers are pegging, thereby improving the fruiting rate and increasing the peanut yield.

[0011] The beneficial effects of this utility model are: increasing the height and amount of soil during peanut cultivation management, ensuring that the peanut pegging reaches the soil during the flowering period, improving the peanut pegging rate and fruiting rate, and automatically adjusting the height of the soil-building mechanism according to the shape of the furrow, thereby improving the efficiency and quality of soil-building and ridge protection.
