Description

Technical Field

[0001] This application relates to the field of rotary tillers, and more specifically, to a high-performance rotary tiller and its assembly. Background Technology

[0002] Rotary tillers are agricultural machines used in conjunction with tractors to perform tilling and harrowing operations. They are widely used due to their strong soil-breaking ability and the ability to create a flat surface after tilling; they also chop up stubble buried below the surface, facilitating seeder operations and providing a good seedbed for later sowing. Based on the configuration of their rotary tiller shafts, they are classified into three types: horizontal shaft, vertical shaft, and inclined shaft. Proper use and adjustment of the rotary tiller are crucial for maintaining its good technical condition and ensuring tillage quality. Rotary tillers break up the plow pan, restore soil structure, improve soil water retention, eliminate some weeds, reduce pests and diseases, level the surface, and improve the standard of agricultural mechanization.

[0003] During the operation of the rotary tiller, the rear plate vibrates up and down and continuously impacts the field ridge or the already tilled soil as it moves with the rotary tiller.

[0004] A high-performance rotary tiller and its assembly are now provided. Utility Model Content

[0055] It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0056] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0057] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0058] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] Reference Figures 1-9 A high-performance rotary tiller and its assembly, comprising: a frame 11, a rear pressure plate assembly 12, a side plate 14, a baffle 25, a fixed base 26, a clamp 27, a shaft tube 13, a gasket 28, a gearbox intermediate shaft 29, a positioning plate 37, and a gantry frame 38.

[0060] The gantry 38 is fixedly connected to the top wall of the frame 11. The positioning plate 37 is fixedly connected to the top wall of the frame 11 and extends to both sides of the frame 11. The gantry 38 and the positioning plate 37 are also fixedly connected, thereby increasing the strength of the frame 11 and the gantry 38. Two side plates 14 are provided and fixedly connected to both ends of the frame 11. The side plates 14 have welding fixture positioning holes 31 for positioning welding fixtures. The welding fixture positioning holes 31 have a tolerance fit with the shaft, thereby achieving the function of installation positioning. A baffle 25 is fixedly connected to the frame 11. One end of the baffle 25 is bent into a Z-shape, and the bent end of the baffle 25 extends to the bottom of the bushing 18. The Z-shape formed by the bending of the baffle 25 and the bushing 18 form a certain barrier (e.g., Figure 6 As shown in the diagram, this prevents mud and water from splashing onto the top of the frame 11 during the operation of the rotary tiller. Furthermore, when the machine is in operation, the rear pressure plate assembly 12 rotates around the axis of the bushing 18, forming a narrow gap between the connecting plate 15, the upper wall of the baffle 25, and the rotating shaft 18. Mud splashes onto the lower wall of the baffle 25, preventing mud from splashing directly above the baffle 25.

[0061] The intermediate shaft 29 of the gearbox is mounted on the frame 11 and is an idler shaft. One end of the intermediate shaft 29 passes through the positioning hole 31 of the welding fixture (e.g., Figure 8(As shown). By providing welding fixture positioning holes 31 on the side plates 14 on both sides, both the width distance between the two side plates 14 and the coaxiality of the two welding fixture positioning holes 31 are ensured. Ultimately, this ensures that the left and right shaft heads of the cutter shaft assembly achieve extremely high coaxiality. This design reduces the adverse effects of radial and axial runout of the cutter shaft on the sealing components and bearings, thereby improving their service life. By passing a portion of the intermediate shaft 29 of the gearbox through one of the welding fixture positioning holes 31, the shear resistance of the connection between the gearbox and the frame 11 is increased.

[0062] The fixed base 26 is fixedly connected to the frame 11. The top wall of the fixed base 26 has two first insertion holes providing space for the clamp 27 to pass through. A gasket 28 is placed on the fixed base 26, and the gasket 28 has two symmetrically positioned second insertion holes, which are U-shaped slots. The clamp 27 is a U-shaped clamp with external threads at both ends. Both ends of the clamp 27 are inserted into the two first insertion holes and the two second insertion holes respectively, and the threaded end of the clamp 27 is threadedly connected to a nut. The clamp 27 and the gasket 28 form a U-shaped space. The shaft tube 13 is fixedly connected to the frame 11 and passes through the gantry 38. One end of the shaft tube 13 passes through the U-shaped space of the clamp 27, and the outer wall of the shaft tube 13 is in abutting contact with the top wall of the gasket 28. By directly inserting the shaft tube 13 into the space formed by the fixing seat 26 and the clamp 27, and inserting a suitable shim 28 according to the distance between the outer wall of the shaft tube 13 and the top wall of the fixing seat 26, the shim 28 is better positioned by engaging with the clamp of the clamp 27 through the second insertion hole of the U-shaped slot structure on the shim 28, thus better limiting the shim 28 and allowing the shaft tube 13 to be better confined within the clamp 27 (e.g., Figure 7 (As shown). It can be applied to shaft tubes 13 of different diameters.

[0063] The frame 11 is equipped with a rear pressure plate assembly 12, which includes: a bushing 18, a connecting plate 15, a round rod 16, a partition 17, a plug 20, and a sealing plate 19.

[0064] The upper end of the connecting plate 15 is fixedly connected to the bushing 18. The round rod 16 is a hollow tube, and plugs 20 are inserted into both ends of the round rod 16. The lower end of the connecting plate 15 is fixedly connected to the outer wall of the round rod 16. The lower end of the partition plate 17 is fixedly connected to the outer wall of the round rod 16, and the upper end of the partition plate 17 is fixedly connected to the connecting plate 15. The lower end of the connecting plate 15, the partition plate 17, and the round rod 16 form a cavity 30. The side walls of the connecting plate 15 and the partition plate 17 are fixedly connected to symmetrically positioned sealing plates 19. The sealing plates 19 are provided with sealing holes for inserting plugs 20 (e.g., ...). Figure 1 , Figure 5 (As shown). By setting the rear pressure plate as a double-layer hollow structure, the overall weight of the rear pressure plate is reduced while ensuring integrity and bending resistance.

[0065] To protect the shaft ends at both ends of the cutter shaft, cutter shaft protective components are also provided, including: a first protective side plate 21, a first protective bottom plate 22, a second protective side plate 23, and a second protective bottom plate 24.

[0066] The first protective side plate 21 is fixedly connected to the side wall of the side plate 14, and the first protective bottom plate 22 is fixedly connected to the bottom wall of the first protective side plate 21. The second protective side plate 23 is fixedly connected to the side wall of the side plate 14, and the second protective bottom plate 24 is fixedly connected to the bottom wall of the second protective side plate 23. The first protective side plate 21 and the first protective bottom plate 22 protect one end of the cutter shaft, and the second protective side plate 23 and the second protective bottom plate 24 wrap and protect the other end of the cutter shaft and the gearbox housing (e.g., ...). Figure 1 , Figure 2 (As shown), to avoid the left and right ends of the cutter shaft and the gearbox directly rubbing or impacting the field ridges when the rotary tiller is in use.

[0067] In order to limit the rear pressure plate assembly 12, two sets of rear pressure plate limiting components are provided and respectively provided on the side plates 14 on both sides. The rear pressure plate limiting component 32 includes: mounting plate 33, handle 35, limiting end 36, and rotating shaft 34.

[0068] Mounting plate 33 is detached and installed on side plate 14 by bolts. A limit link is installed on one side of mounting plate 33. The limit link includes a handle 35 installed on one side of mounting plate 33 and a limit end 36 passing through the other side of mounting plate 33. Rotating shaft 34 is fixedly connected to mounting plate 33, and bushing 18 is sleeved on rotating shaft 34. Bushing 18 rotates relative to rotating shaft 34.
