Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural equipment and relates to a tractor farmland deep plowing device. Background Art

[0002] As we all know, the deep plowing function of agricultural tractors is to deeply turn over the soil in the farmland, thereby improving the soil structure. The plowed soil is suitable for the next crop planting. The plowing depth of the prior art plowing device is generally about 30 cm, which can meet the planting needs of most existing crops. The plowing depth exceeding 30 cm is difficult for general plowing devices to achieve. Taking wheat planting as an example, the plowing depth of wheat can be 25-30 cm. The so-called deep plowing and shallow sowing refers to a plowing depth of 20-30 cm and a sowing depth of 3-5 cm. Deep plowing is considered deep plowing when it reaches about 30 cm.

[0003] The farmland after plowing needs to be rotary tilled, and the farmland after rotary tillage is conducive to the sowing of crops. There is no problem for the rotary tiller to perform rotary tillage on the farmland after conventional plowing. If the plowing depth is exceeded, the rotary tiller cannot work. Because the soil cutting blades of the rotary tillage device in the prior art are all arc-shaped blades, the biggest disadvantage of the arc-shaped blade is that the blade has a large resistance to entering the soil, the deep plowing ability is insufficient, and the soil entry depth is too deep to operate normally.

[0004] However, in recent years, many places have returned abandoned land to farmland or reclaimed new wasteland, and the soil structure has been severely damaged. A deeper plowing depth than the existing deep plowing requirements is required to cooperate with the rotary tillage operation of the rotary tiller. Therefore. Our team has designed a variety of deep plowing blades through many experiments and studies in recent years. We have conducted experiments and studies in mountainous areas, abandoned wasteland or farmland return sites, invited domestic agricultural machinery experts to observe on-site, listened to various opinions, and continuously modified the design plan. Through on-site testing of plowed fields after plowing, the plowing depth reached more than 40 cm, and the rotary tiller can easily perform soil rotary tillage, and achieved satisfactory test results.

[0005] In order to overcome the deficiencies in the prior art, the utility model discloses a tractor farmland deep plowing device, which achieves the purpose of improving deep plowing efficiency by arranging a self-designed straight plate-shaped soil cutting blade on a rotating shaft.

[0006] In order to achieve the above-mentioned purpose of the invention, the utility model adopts the following technical scheme: a tractor farmland deep plowing device, comprising: a soil cutting blade and a plowing rotating shaft; a soil cutting blade is arranged on the plowing rotating shaft, and the soil cutting blade is spirally and equidistantly arranged on the plowing rotating shaft with the center line of the plowing rotating shaft as the axis, and the soil cutting blade is a straight plate-like structure.

[0007] The soil cutting blade and the plowing rotating shaft are fixedly connected.

[0008] The soil cutting blade and the plowing rotating shaft are in a detachable connection structure.

[0009] The angles a between the soil cutting blades are the same, and the angle a between two adjacent soil cutting blades is 120°. The center line of the rotation axis is perpendicular to the plane where each soil cutting blade is located, and the distances between the planes where each soil cutting blade is located are the same and parallel to each other.

[0010] The dimensions of various parts of the soil cutting blade are as follows: the flat angle A between the blade tip bevel and the upper surface of the blade handle is 59.2±1°, the blade tip and the inner arc B of the blade body are R50±1°, the blade body arc C is R145.28±1°, the effective length D of the blade is 268.53±1mm, the blade tip and the outer arc E of the blade body are R10±1°, and the blade body width G is 50-80mm.

[0017] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the claims of the present invention.

[0018] like Figures 1 to 3As shown, a tractor farmland deep plowing device includes: a soil cutting blade 1 and a plowing rotating shaft 2; the plowing rotating shaft 2 is provided with a soil cutting blade 1, and the soil cutting blade 1 is spirally and equidistantly arranged on the plowing rotating shaft 2 with the center line of the plowing rotating shaft 2 as the axis, and the soil cutting blade 1 is a straight plate structure. According to the specific use, the soil cutting blade 1 and the plowing rotating shaft 2 can be a fixed connection structure, or the soil cutting blade 1 and the plowing rotating shaft 2 can also be a detachable connection structure.

[0019] The soil cutting blades 1 are arranged in a spiral shape and at equal distances around the plowing rotation axis 2. The angle a between adjacent soil cutting blades 1 is the same, and the angle a between two adjacent soil cutting blades 1 is 120°. The center line of the rotation axis is perpendicular to the plane where each soil cutting blade 1 is located, and the distance between the planes where each soil cutting blade 1 is located is the same and parallel to each other.

[0020] The dimensions of various parts of the soil cutting blade 1 are as follows: the angle A between the blade tip bevel and the upper surface of the blade handle is 59.2±1°, the blade tip and the inner arc B of the blade body are R50±1°, the blade body arc C is R145.28±1°, the effective length D of the blade is 268.53±1mm, the blade tip and the outer arc E of the blade body are R10±1°, and the blade body width G is 50-80mm.

[0021] When working, as the tractor drives the plowing device into the plot, the plowing rotating shaft 2 drives the straight plate-shaped soil cutting blade 1 to easily enter the soil. The plowing rotating shaft 2 can choose to rotate forward or reverse to make the soil cutting blade 1 enter the soil for plowing. It can play a better role in mountainous areas, abandoned wasteland or land reclamation sites. The plowing depth can reach more than 40 cm.

[0022] The soil cutting blade 1 and the plowing rotating shaft 2 are fixedly connected or detachably connected. The detachably connected soil cutting blade 1 has a greater buffering effect after entering into soil with a relatively hard texture.

[0023] The angles between the soil cutting blades 1 are the same, the angle between two adjacent soil cutting blades 1 is 120°, and every three soil cutting blades 1 form a group. Each group of soil cutting blades 1 on the plowing rotation axis 2 is cross-arranged on the plowing rotation axis 2 so that the angle between the soil cutting blades 1 is 60°, so that the soil is plowed more evenly when the plowing rotation axis 2 rotates. The center line of the plowing rotation axis 2 is perpendicular to the plane where each soil cutting blade 1 is located, and the distance between the planes where each soil cutting blade 1 is located is the same and parallel to each other. In order to obtain a better deep plowing effect, the distance between the soil cutting blades 1 can be adjusted.

[0024] In this embodiment, when the plowing device is in use, the deep plowing device is set at the rear of the tractor by utilizing the traction of the tractor, and then the plowing rotating shaft 2 is rotated by the drive of the motor, and the plowing rotating shaft 2 can be turned over to select the rotation direction of the soil cutting blade 1. The straight-plate soil cutting blade 1 can penetrate into the soil, easily turn out the soil inside the soil, and break the weed roots in the deep soil. It only needs to adjust the distance between the soil cutting blades 1. The efficiency and uniformity of the plowing have been fully confirmed in practice. Repeated plowing is avoided. These features are not possessed by other types of soil cutting blades, especially the side-turning soil cutting blades currently used, which have a limited deep plowing depth and cannot penetrate into the soil. At the same time, it requires greater traction to enter the soil, which makes it inefficient. The soil cutting blade 1 of the utility model can be selected with a blade or without a blade. For loose soil, the soil cutting blade 1 without a blade can better penetrate into the ground to bring out the soil, thereby further improving the deep plowing efficiency.

[0025] The parts of the present invention that are not described in detail are prior art, and the above description is only a preferred embodiment of the present invention. However, those skilled in the art should understand that various changes can be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined in the attached claims, and all of these are within the scope of protection of the present invention.
