Description

Technical Field

[0001] This invention belongs to agricultural machinery and mainly relates to a stubble pulverizing component. Background Technology

[0002] The stubble-crushing component on rotary tillage and stubble-crushing machinery is a key component that influences and determines the quality and effectiveness of stubble crushing. Currently, planar single-layer horizontal rotating stubble-crushing components have been developed and applied. This component is a technological product that differs from the traditional vertical rotating L-shaped or Y-shaped stubble-crushing components. However, due to shortcomings in structural design, existing single-layer horizontal stubble-crushing components cannot adjust their height and entry angle according to the location and length of the stubble, as well as differences in soil conditions. Furthermore, they lack the function and capability for three-dimensional operation, resulting in poor adaptability, high power consumption, rapid blade wear, short lifespan, high operating costs, and poor stubble crushing quality, all of which need to be overcome and resolved. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art and, in combination with the actual needs of current stubble pulverizing operations, to develop and design a three-dimensional horizontal stubble pulverizing unit with adjustable height and angle. This unit can adjust the height and angle of the stubble pulverizing blades during operation according to the height of the stubble, the length of the stubble stems, and the soil conditions. This achieves the goals of strong applicability, significantly improving the quality and effect of stubble pulverizing operations during cultivation, reducing power consumption, reducing blade wear, extending service life, and saving operating costs.

[0004] The objective of this invention is achieved as follows: A fork-type rocker arm is vertically and rotatably hinged to a fixed base via a hinge pin. A spline shaft is axially and radially positioned and circumferentially rotatable on the fork-type rocker arm via a support pin. A spline sleeve is circumferentially and radially positioned and axially movable on the outside of the spline shaft. A hollow motor is fixedly mounted and positioned on the outside of the spline sleeve. An upper bushing is fixedly mounted on the upper end of the spline sleeve, located outside the hollow motor. Six support arms are evenly distributed circumferentially on the outer part of the upper bushing. Two short hangers, two medium hangers, and two long hangers are sequentially and alternately suspended from each of the six support arms circumferentially. Drive blocks are fixedly mounted on the lower ends of the short, medium, and long suspension rods, respectively; a lower bushing is fixedly mounted on the bottom end of the spline shaft; two support rods A, B, and C are sequentially fixedly mounted on the outside of the lower bushing, arranged alternately from top to bottom and along the circumferential direction; L-shaped cutter holders are vertically and reciprocally mounted on the outer sides of the two support rods A, B, and C, respectively; stubble pulverizing blades are fixedly mounted on the L-shaped cutter holders; the upper and lower ends of the push-pull rod are respectively hinged to the drive blocks and the L-shaped cutter holders; the hinge point between the lower end of the push-pull rod and the L-shaped cutter holder is eccentrically positioned with respect to the axis of support rods A, B, and C, thus forming a three-dimensional horizontal stubble pulverizing unit with adjustable height and angle.

[0005] This invention enables stepless adjustment of the height of the stubble-crushing blades and the angle of their entry into the soil for stubble crushing and tillage during operation. Combined with the installation structure of upper, middle and lower three-layer stubble-crushing blades, it completes three-dimensional stubble crushing operation. It features a novel, unique and reasonable structure, strong applicability, good operation quality and effect, low power consumption, light blade wear, long service life and low operating cost.

[0012] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0013] A height- and angle-adjustable three-dimensional horizontal stubble-crushing unit is mounted on a fixed base 1, with a fork-type rocker arm 17 hinged vertically and rotatably via a hinge pin 18. A splined shaft 2 is axially and radially positioned and circumferentially rotatable on the fork-type rocker arm 17 via a support pin 16. A splined sleeve 9 is circumferentially and radially positioned and axially movable on the outside of the splined shaft 2. A hollow motor 15 is fixedly mounted and positioned on the outside of the splined sleeve 9. An upper bushing 3 is fixedly mounted on the upper end of the splined sleeve 9, located outside the hollow motor 15. Six support arms 4 are evenly distributed circumferentially on the outer part of the upper bushing 3. Two long hanging rods 8 and a middle hanging rod are sequentially and spaced apart from each other circumferentially on the six support arms 4. The rod 13 and the short hanging rod 14 are respectively fixed with drive blocks 19 on the lower ends of the long hanging rod 8, the middle hanging rod 13 and the short hanging rod 14; the lower bushing 10 is fixed on the bottom end of the spline shaft 2; two support rods A7, B11 and C12 are fixed in sequence from top to bottom and in a staggered manner along the circumferential direction on the outside of the lower bushing 10; L-shaped knife holders 5 are respectively installed on the outer parts of the two support rods A7, B11 and C12, which can be vertically reciprocated; the stubble pulverizing blade 6 is fixed on the L-shaped knife holder 5; the upper and lower ends of the push-pull rod 20 are respectively hinged to the drive block 19 and the L-shaped knife holder 5; the position of the hinge point between the lower end of the push-pull rod 20 and the L-shaped knife holder 5 is eccentrically configured with respect to the axis of the support rods A7, B11 and C12.

[0014] During operation, the hollow motor 15 is started. The rotation of the hollow motor 15 causes the spline sleeve 9 to drive the upper shaft sleeve 3 and the spline shaft 2 to rotate synchronously. The rotating ground shaft sleeve 3 drives the long hanging rod 8, the middle hanging rod 13 and the short hanging rod 14 to revolve around the axis of the spline shaft 2 through the support arm 4. The rotating ground spline shaft 2 drives the stubble pulverizing blade 6 to revolve around the axis of the spline shaft 2 through the lower shaft sleeve 10 and the L-shaped blade holder 5. The stubble pulverizing blade 6, which is configured in three layers (upper, middle and lower), completes the stubble pulverizing, pulverizing and rotary tillage of the roots, stubble, stems and soil. When the height and rotary tillage angle of the stubble-crushing blade 6 need to be adjusted according to the stubble, stems, and soil conditions, the external drive power causes the fork-type rocker arm 17 to swing vertically around the hinge pin 18 on the fixed base 1. Through the support pin 16, the spline shaft 2, lower bushing 10, support rod A7, support rod B11, support rod C12, and L-shaped blade holder 5 are driven in sequence to change the vertical height of the stubble-crushing blade 6. At the same time, under the control of the hollow motor 5, which remains stationary in height position, the spline sleeve 9... The L-shaped blade holder 5, whose height position remains unchanged but whose vertical position changes, is pulled or pushed upwards by the drive block 19 fixed at the lower part of the long, medium, and short hanging rods 8, 13, and 14. Through the push-pull rod 20, the L-shaped blade holder 5 drives the stubble pulverizing blade 6 to rotate around the support rods A7, B11, and C12 in the vertical direction, thus simultaneously completing the rotary tillage and stubble pulverizing angle adjustment of the stubble pulverizing blade 6.

[0015] This invention achieves significant and outstanding technical results by steplessly adjusting the height of the three-layer stubble-crushing blades 6 and the angle of rotary tillage and stubble-crushing. This is achieved while ensuring the quality and effectiveness of rotary tillage and stubble-crushing operations, improving the adaptability of individual operations, expanding the scope of application, reducing blade wear, extending service life, and reducing power consumption and operating costs.
