Abstract
Description
Technical Field
[0001] This invention relates to the field of rotary tillage equipment technology, specifically to a multifunctional composite rotary tillage harrow. Background Technology
[0002] Agriculture is a rapidly developing industry, and tillage machines are common agricultural equipment. Currently, there are two common types of rotary tillage harrows: one without a ridging component, which can only be used for tilling and harrowing; if ditching and ridging are needed, manual labor is required, which is time-consuming and labor-intensive. The other type has a ridging component, which can both till and harrow and ridge simultaneously, but this component is fixed and cannot be removed. Therefore, it is not suitable for large-scale field tillage where ridging is not required. Both types have limited applicability and relatively simple functions, making it difficult to keep up with the needs of agricultural development. This paper proposes developing a composite rotary tillage harrow that can complete "rotary tillage + leveling + ditching and ridging" in one operation, thus contributing to agricultural development. Summary of the Invention
[0003] This invention provides a multifunctional composite rotary tillage harrow with multiple functions and high applicability. The required functions can be adjusted according to needs, making it easy to use in both field tillage and greenhouse cultivation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.
[0025] Please see Figures 1 to 6 As shown, a multifunctional composite rotary tillage harrow includes a rotary tillage frame 1, a rotary tillage blade 3 installed under the rotary tillage frame 1, and a transmission structure 2 that transmits driving force to the rotary tillage blade 3. The rotary tillage frame 1 is also equipped with a ditching and ridging mechanism 4, a leveling mechanism 5, and a furrow compaction mechanism 6.
[0026] The ditching and ridging mechanism 4 is symmetrically and liftably arranged at both ends of the rotary tiller 1, and is used to ditch and rid the field as needed. The leveling mechanism 5 is movably arranged at the rear end of the rotary tiller 1, and is used to smooth the surface of the field after tilling and harrowing and to press the remaining roots of crops into the soil. The furrow compaction mechanism 6 is height-adjustable and arranged at the rear end of the rotary tiller 1 and above the leveling mechanism 5, and is used to trim and compact the furrows.
[0027] Please see Figure 3 As shown, the transmission structure 2 includes a coupling assembly 21, a transmission shaft 22, and a transmission gear 23. The coupling assembly 21 is located on the top of the rotary tiller frame 1 and is used to connect with the output shaft of the rotary tiller so that the rotary tiller can drive the rotary tiller blade 3. The transmission gear 23 is located at one end of the rotary tiller frame 1 and meshes with the input end of the rotary tiller blade 3. One end of the transmission shaft 22 is connected to the coupling assembly 21, and the other end is connected to the transmission gear 23.
[0028] Please see Figure 4 As shown, the ditching and ridging mechanism 4 includes a connecting rod hinge 41, a ditching and ridging frame 43, a ditching hydraulic telescopic cylinder 42, a ditching plow 44, and a ridging component 45. The connecting rod hinge 41 is located on the top end of the rotary tiller 1. The ditching and ridging frame 43 is located on the connecting rod hinge 41. The ditching hydraulic telescopic cylinder 42 is located on the top of the rotary tiller 1 and connected to the ditching and ridging frame 43, used to raise or lower the ditching and ridging frame 43. The ditching plow 44 is located at the front end of the ditching and ridging frame 43. The ridging component 45 is located at the rear end of the ditching and ridging frame 43. The surface of the ridging component 45 is curved and slightly inclined, and the area gradually increases from bottom to top.
[0029] In actual tillage operations, such as in greenhouse vegetable fields, where it is necessary to dig and rid the field, the ditching and ridging frame 43 is lowered by driving the ditching hydraulic telescopic cylinder 42. This allows the ditching plow 44 and the ridging component 45 to dig and rid the field simultaneously while tilling and harrowing. The ditching and ridging mechanism 4 is symmetrically arranged at the ends of the rotary tiller 1. Both ends of the ditching and ridging mechanism 4 can be lowered for operation according to actual needs, or only one end can be lowered. If ditching and ridging are not required, the ditching hydraulic telescopic cylinder 42 can be used to directly lift the ditching and ridging mechanism 4. This method is applicable to both paddy fields that do not require ditching and ridging and greenhouse vegetable fields that do require ditching and ridging.
[0030] Please see Figure 5 and Figure 6 As shown, the leveling mechanism 5 includes a leveling frame 51, several pressing rods 52, a leveling plate 53, and a connecting rod adjustment assembly 54. The leveling frame 51 is hinged to the rear end of the rotary tiller 1. The pressing rods 52 are evenly distributed at the bottom of the leveling frame 51. The leveling plate 53 is hinged to the rear end of the leveling frame 51. The working end of the leveling plate 53 is serrated, which can better smooth the soil surface after rotary tillage. One end of the connecting rod adjustment assembly 54 is set on the rotary tiller 1, and the other end is connected to the leveling plate 53. The tilt of the leveling plate 53 can be adjusted through the connecting rod adjustment assembly 54.
[0031] In actual operation, the flattening mechanism 5 can smooth the surface of the field after rotary tillage. The pressing bar 52 can press the plant roots and stems that have been tilled into the soil, which can make the plant roots and stems better become fertilizer for the soil. The flattening plate 53 can smooth the surface of the land. The connecting rod adjustment component 54 can adjust the inclination of the flattening plate 53 according to actual needs.
[0032] The linkage adjustment assembly 54 includes an adjustment seat 541, an adjustment link 542, a limiting member 543, a locking member 544, and a handle 545. The adjustment seat 541 is mounted on the rotary tiller 1. One end of the adjustment link 542 is connected to the adjustment seat 541, and the other end is connected to the leveling plate 53. The limiting member 543 is mounted on the adjustment link 542 and extends one end to the adjustment seat 541. The locking member 544 is mounted on the adjustment seat 541 and corresponds to the limiting member 543. There is also a spring between the locking member 544 and the adjustment seat 541, which can provide a certain reset force to the locking member 544. The handle 545 is mounted on the locking member 544. By pulling the handle 545, the locking member 544 pulls the limiting member 543, thereby adjusting the inclination of the leveling plate 53. The limiting member 543 is provided with a limiting shaft 546, and the locking member 544 is provided with a locking groove 547 corresponding to the limiting shaft 546.
[0033] When adjusting, the lifting handle 545 can drive the locking component 544 to rotate, so that the locking groove 547 and the limiting shaft 546 match and correspond. The limiting shaft 546 falls into the locking groove 547, thereby pulling the limiting component 543 to move accordingly. Finally, the flat plate 53 is pulled up, and the tilt angle will become smaller. If the handle 545 is pushed, the opposite will happen.
[0034] Please see Figure 7 As shown, the furrow compaction mechanism 6 includes a compaction frame 61, a compaction hydraulic telescopic cylinder 62, and a compaction roller assembly 63. The compaction frame 61 is hinged to the rear end of the rotary tiller 1. The compaction hydraulic telescopic cylinder 62 is mounted on the rotary tiller 1 and connected at one end to the compaction frame 61 for raising or lowering the compaction frame 61. The compaction roller assembly 63 is mounted on the compaction frame 61. When the compaction frame 61 is in the lowered state, the compaction roller assembly 63 can compact and trim the furrow.
[0035] The compaction roller assembly 63 includes a rolling shaft 631, a hydraulic motor 632, a compaction roller 633, and a trimming disc 634. The rolling shaft 631 is mounted on the compaction frame 61, the hydraulic motor 632 is mounted on one end of the rolling shaft 631, the compaction roller 633 is fitted onto the rolling shaft 631, and the trimming disc 634 is mounted on both ends of the compaction roller 633. The hydraulic motor 632 drives the compaction roller 633 and the trimming disc 634 to rotate, thereby compacting and trimming the furrows.
[0036] When furrow trimming is required, the hydraulic telescopic cylinder 62 drives the compaction frame 61 to descend, while the hydraulic motor 632 drives the compaction roller 633 to rotate, and the trimming disc 634 also rotates, thereby compacting and trimming the sides of the furrow. Because the compaction roller 633 and the trimming disc 634 are powered, the furrow trimming process is more even and secure.
[0037] This invention has multiple functions and high applicability; the ditching and ridging mechanism 4, the leveling mechanism 5, and the furrow compaction mechanism 6 can be adjusted and used according to needs, so that the rotary tillage harrow can complete "rotary tillage + leveling + ditching and ridging" in one go, and the functions can also be combined according to the usage environment and needs to meet the needs of various arable land planting.
[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
