Description

Technical Field

[0001] The utility model relates to the field of crop planting, in particular to a soil cultivating mechanism. Background Art

[0002] In the field of planting agricultural cash crops such as tobacco, when the crops grow to a certain stage, it is generally necessary to add soil to the ridges where the crops grow, that is, weeding is done on both sides of the ridges where the crops grow, and the soil at the bottom and sides of the ridges is piled on the roots of the crops to improve the growth quality of the crops and thus increase the yield. Traditionally, adding soil is usually done by people using hand-held tools, but currently, a soil-adding machine is generally used for adding soil. In southern Hunan, due to the high toughness and viscosity of the soil, if the soil is to be accurately added to the roots of the crops, the soil-adding capacity of the soil-adding machine is extremely high.

[0003] In the existing soil-raising machines, the soil-raising plows are horizontally distributed on a plow shaft. When the plows are performing soil-raising operations, the rotating surface of the plow is always perpendicular to the horizontal plane. After the soil is dug up, it is thrown onto the ridge surface on one side or both sides by the soil-raising blades. When the soil is clay soil with high moisture content, especially when there is water accumulation and the bottom of the ditch is in a muddy state, the lateral throwing effect is poor due to the influence of the soil viscosity, and it is even impossible to raise the soil for the roots of the crops. Therefore, the current soil-raising machines cannot meet the soil-raising needs of the crops in the area. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a soil-building mechanism to improve the soil-building effect and to be suitable for soil with greater viscosity.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A soil-raising mechanism, comprising a transmission assembly, a transmission box and a plowshare soil-throwing assembly;

[0007] In the axial direction of the transmission assembly, both ends of the transmission assembly are respectively connected to the corresponding plow blade soil throwing assembly through a transmission box, and the two plow blade soil throwing assemblies are arranged opposite to each other, and the two transmission boxes are arranged opposite to each other;

[0008] The axis of the transmission assembly is distributed in the horizontal direction;

[0009] The axis of the plow blade throwing assembly and the axis of the transmission assembly form an angle greater than 10° and less than 30°;

[0010] Along the direction from the transmission assembly to the plow blade soil throwing assembly, the distance between the two transmission boxes gradually increases.

[0011] Further, the transmission assembly includes a clutch and an adjustment assembly;

[0012] The two axial ends of the clutch are respectively transmission-connected to one of the adjustment components;

[0013] The adjusting assembly is drivingly connected to the input end of the corresponding transmission box.

[0014] Further, the adjustment assembly includes a first coupling and a second coupling;

[0015] The first coupling is transmission-connected to the clutch;

[0016] The second coupling is connected to the transmission box, and the first coupling is hinged to the second coupling.

[0017] Furthermore, the axis of the plow blade throwing assembly is perpendicular to the length direction of the transmission box.

[0018] Furthermore, the plow blade soil throwing assembly comprises a blade shaft and a soil throwing blade;

[0019] The soil throwing knife is transmission connected with the transmission box through the knife shaft.

[0020] Furthermore, the soil throwing knife includes at least three blades which are arranged at equal intervals around the knife axis.

[0021] Furthermore, the plow blade throwing soil assembly is drivingly connected to the output end of the transmission box.

[0022] The beneficial effects of the present utility model are as follows: by setting a plowshare soil throwing assembly and forming an angle of 10 to 30 degrees between the axis of the plowshare soil throwing assembly and the axis of the transmission assembly, it can adapt to the shape of the ridge side, so that the rotating surface of the plowshare soil throwing mechanism can deeply dig and weed the soil surface on the ridge side and the ridge base, and at the same time, the dug up broken soil and broken grass can be thrown onto the crop roots on the top of the ridge according to a parabolic motion trajectory. Compared with the existing soil-raising machines, the performance and effect of soil extraction, weeding and soil throwing are improved and improved, and the soil-raising requirements of soil with high moisture and high viscosity can be met. The present application adopts an inclined plowshare soil throwing assembly to overcome the defects of the existing soil-raising machines, such as poor soil throwing effect and unreliable performance for soil with high viscosity, and improves the digging depth and soil throwing force without increasing the driving force, making it more suitable for soil with high viscosity.

[0030] It is understandable that by setting up the plow blade soil throwing assembly 3 and forming an angle α of 10 to 30° between the axis of the plow blade soil throwing assembly 3 and the axis of the transmission assembly 1, it can adapt to the shape of the ridge side, so that the rotating surface of the plow blade soil throwing assembly 3 can deeply dig and weed the soil surface on the ridge side and the ridge base part, and at the same time, the excavated broken soil and broken grass can be thrown to the crop roots on the top of the ridge according to a parabolic motion trajectory.
