Description

Technical Field

[0001] The utility model relates to the technical field of rotary tillers, in particular to a rotary tiller with adjustable spacing for corn planting. Background Art

[0002] At present, before planting corn on a large scale, a rotary tiller is generally used to loosen the land. The loosening work can be completed in a short time, which is convenient for the subsequent sowing of corn. The rotary tiller is a tilling machine that is matched with a tractor to complete the plowing and harrowing operations. The rotary tiller has the functions of breaking the plow bottom layer, restoring the soil tillage layer structure, improving the soil's ability to store water and retain moisture, eliminating some weeds, reducing pests and diseases, leveling the surface, and improving the standards of agricultural mechanization operations.

[0003] In the prior art, for example, Chinese patent CN215453851U discloses a rotary tiller with adjustable spacing for corn planting, comprising a rotary tiller body, a rotary tiller lifting mechanism being provided at one end of the rotary tiller body, a rotary tiller head shell being provided at one end of the rotary tiller head shell, a rotary tiller scraper being provided at one end of the rotary tiller scraper, scraper tilling teeth being provided under the rotary tiller scraper, a rotary tiller rotating shaft plate being provided at the other end of the rotary tiller head shell, a rotary tiller rotating shaft plate being rotatably connected to a rotary tiller rotating shaft at one end of the rotary tiller rotating shaft, and a rotary tiller tilling teeth being provided at one end of the rotary tiller rotating shaft.

[0004] However, in the prior art, since corn planting can adapt to a wide variety of soil types, the existing rotary tillers generally have a relatively fixed distance between the rotating teeth, and cannot adjust the turning distance according to the looseness of the soil. When the soil is too dense and the distance between the rotating teeth is small, the torque applied to the rotating teeth is too large, thereby causing damage to the rotating teeth. Therefore, the present application provides a rotary tiller with adjustable distance for corn planting to meet the needs. Utility Model Content

[0028] like Figure 1 - Figure 4As shown, the embodiment of the utility model provides a rotary tiller with adjustable pitch for corn planting, comprising: a mounting cover 1, a rotary tillage pitch adjustment mechanism 3 is arranged inside the mounting cover 1, the rotary tillage pitch adjustment mechanism 3 comprises a rotating rod 312 and a plurality of groups of X-shaped movable parts 33, the two ends of the rotating rod 312 are respectively rotatably connected to the two sides of the mounting cover 1, the outer wall of the rotating rod 312 is fixedly connected with two groups of limit strips 313, the outer wall of the rotating rod 312 is provided with a plurality of groups of rotating wheels 36, the inner walls of the plurality of groups of rotating wheels 36 are provided with two groups of grooves 311, and the plurality of groups of rotating wheels 36 are respectively connected with the two groups of limit strips 313 through the two groups of grooves 311. The outer wall of the strip 313 is clamped, the outer wall of the rotating wheel 36 is rotatably connected to the rotating seat 35, the upper surface of the rotating seat 35 is fixedly connected to two groups of bent rods 34, the multiple groups of X-shaped movable parts 33 are arranged in a straight line, and the two adjacent groups of X-shaped movable parts 33 are rotatably connected to each other through the two groups of bent rods 34, the two ends of the two groups of X-shaped movable parts 33 at the two ends are respectively movably connected to two groups of V-shaped movable parts 39 through the two groups of bent rods 34, the tip positions of the two groups of V-shaped movable parts 39 are rotatably connected to the concave blocks 32, the outer walls of the two groups of concave blocks 32 are fixedly connected to the hydraulic rods 31, and the two groups of hydraulic One end of the pressure rod 31 is fixed to the inner wall of the mounting cover 1, and both sides of the rotating wheel 36 are threadedly connected with multiple sets of fixing bolts 310. Two sets of left-rotating blade teeth 37 are fixedly installed on one side of the rotating wheel 36 through multiple sets of fixing bolts 310, and two sets of right-rotating blade teeth 38 are fixedly installed on the other side of the rotating wheel 36 through multiple sets of fixing bolts 310. By starting the hydraulic rods 31 at the same time, the telescopic ends of the two sets of hydraulic rods 31 are extended, driving the concave blocks 32 to move closer to each other, further driving the opening and closing angles of the V-shaped movable parts 39 to increase, and further driving the cross-joint of the multiple sets of X-shaped movable parts 33 The angle increases, so that the multiple groups of curved rods 34 are close to the center position of the rotating rod 312 and the rotating seat 35. At this time, the rotating seat 35 drives the rotating wheel 36 to slide along the limiting strip 313 through the groove 311, and the multiple groups of rotating seats 35 are adjusted to a suitable position to stop the extension of the hydraulic rod 31, and the spacing adjustment of the rotating teeth is completed. When the two groups of hydraulic rods 31 are extended to the maximum length, the left rotating teeth 37 and the right rotating teeth 38 on the two adjacent groups of rotating wheels 36 are not in contact, so the left rotating teeth 37 and the right rotating teeth 38 can be protected from being damaged due to mutual rotation and collision.

[0029] like Figure 1 - Figure 4As shown, the X-shaped movable member 33 is composed of two long rods and a rotating shaft, and the middle positions of the two rods are rotatably connected through the rotating shaft. The V-shaped movable member 39 is composed of two short rods and a rotating shaft, and the ends of the two short rods are rotatably connected through the rotating shaft. The side walls of the rotating rod 312 are fixedly connected with the edge rotating teeth 30 near the two ends. The upper end of the mounting cover 1 is movably connected with the mechanical arm 2.

By starting the hydraulic motor 4, the hydraulic motor 4 drives the rotating rod 312 to rotate. Due to the limiting effect of the limiting strip 313 and the groove 311 on the rotating wheel 36, the rotating rod 312 drives the rotating wheel 36 to rotate in the rotating seat 35 when rotating, further drives the left-rotating blade teeth 37 and the right-rotating blade teeth 38 to rotate, and at the same time drives the two groups of side-rotating blade teeth 30 to rotate, so as to perform a rotary tillage operation on the soil.

At this time, the rotating seat 35 drives the rotating wheel 36 to slide along the limiting strip 313 through the groove 311, and the multiple groups of rotating seats 35 are adjusted to a suitable position to stop the extension of the hydraulic rod 31, and the work is completed. The spacing between the rotating blade teeth is adjusted. When the two groups of hydraulic rods 31 are extended to the maximum length, the left-rotating blade teeth 37 and the right-rotating blade teeth 38 on the two adjacent groups of rotating wheels 36 are not in contact. Therefore, the left-rotating blade teeth 37 and the right-rotating blade teeth 38 can be protected from being damaged due to mutual rotation and collision. Then, the mounting cover 1 is placed on the ground through the mechanical arm 2, and the hydraulic motor 4 is started. The hydraulic motor 4 drives the rotating rod 312 to rotate. Due to the limiting effect of the limiting strip 313 and the groove 311 on the rotating wheel 36, the rotating rod 312 drives the rotating wheel 36 to rotate in the rotating seat 35 when rotating, and further drives the left-rotating blade teeth 37 and the right-rotating blade teeth 38 to rotate, and at the same time drives the two groups of side-rotating blade teeth 30 to rotate, so as to perform rotary tillage operations on the soil.
