Description

Technical Field

[0001] This utility model relates to the field of speed transmission technology, specifically a variable speed transmission device for tillage machine compaction operations. Background Technology

[0002] After the tiller is attached to the tractor, the tractor's output power is transmitted to the tiller's transmission device via the drive shaft. By switching gears, the speed of each working part is adjusted. Then, the plow blades or rotary tillers enter the soil and rotate, breaking up the compacted soil and removing crop residues in the field. Next, the harrow teeth or scrapers follow to comb the surface, smooth the furrows, and evenly distribute the fine soil clods. Finally, the compaction roller rolls to compact the soil, reducing gaps to lock in moisture. The whole process is completed in one go, ultimately forming a loose, flat seedbed suitable for seed implantation.

[0003] During the operation of the tiller, it is difficult to adjust the differential speed in the device according to the needs. At the same time, the internal mechanism of the tiller is a whole, making the maintenance process cumbersome and the work efficiency low. During the operation of the tiller, the vibration can cause the drive shaft to suddenly extend or shorten, and if it cannot be restored to its original state in time, it will lead to damage to the device. Utility Model Content

[0004] The purpose of this invention is to provide a variable speed transmission device for tillage pressing operations, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A variable speed transmission device for tillage compaction includes a transmission component comprising two connecting splined shafts, both ends of which are fixedly connected to a transmission assembly. The surface of each transmission assembly has a first protective component. One end of each transmission assembly meshes with a connecting shaft. A differential component includes a connecting shaft with a first bevel gear fixedly connected to the middle of its surface. A second bevel gear meshes with the surface of the first bevel gear. A second protective component is fixedly connected to one side of the surface of the second bevel gear. One end of the second bevel gear meshes with a first cylindrical gear. The surface of the first cylindrical gear meshes with a second cylindrical gear. One side of the second cylindrical gear meshes with a power input shaft. A mounting component includes a roller body with one side meshing with one end of the transmission assembly. One end of the transmission assembly is fixedly connected to a connecting rod, and one end of the connecting rod is fixedly connected to a mounting assembly.

[0006] Preferably, the transmission assembly includes a first transmission shaft, one end of which is engaged with one end of a connecting spline shaft, the other end of which is engaged with a first transmission gear, a second transmission gear being engaged on the surface of the first transmission gear, a second transmission shaft being fixedly connected inside the second transmission gear, and one end of the second transmission shaft being engaged with one end of a connecting shaft.

[0007] Preferably, the first protective component includes two first bearings, the inner walls of the two first bearings are fixedly connected to both sides of the surface of the first drive shaft, a first housing is fixedly connected to the surface of the first bearings, a flange connecting pipe is fixedly connected to one end of the first housing, a second housing is fixedly connected to the other end of the first housing, two second bearings are fixedly connected inside the second housing, and the inner walls of the second bearings are fixedly connected to one side of the surface of the second drive shaft.

[0010] Preferably, the fourth bearings are identical in pairs and are symmetrically distributed on both sides of the connecting shaft surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This tillage machine's press operation can be controlled by a speed-changing transmission device. Through the connection of a splined shaft, a transmission assembly, and a first protective assembly, during operation, the second transmission shaft, in cooperation with the second transmission gear, drives the first transmission shaft within the first housing, which in turn drives the first transmission shaft to rotate within the flange connecting pipe. The first transmission shaft, in turn, drives the second transmission shaft to rotate through the cooperation of the first and second transmission gears. This allows the second transmission shaft to simultaneously drive the connecting rod and the roller to rotate, achieving the effect of facilitating maintenance and reducing costs.

[0012] This tillage machine features a variable speed transmission device for compaction operations. Through the arrangement of a first bevel gear, a second bevel gear, a first cylindrical gear, and a second cylindrical gear, the rotation of the power input shaft during operation drives the first cylindrical gear to rotate via the second cylindrical gear. The second bevel gear, in conjunction with a third bearing, then drives the first bevel gear within the main housing. By utilizing the speed ratio difference between the first and second cylindrical gears and the speed ratio difference between the first and second bevel gears, the device adapts to different usage scenarios, thus improving its versatility.

The design of the mounting plate, mounting frame, reinforcing plate, positioning bolts, and fixed frame distributes the pressure generated by the roller offset, improving the load-bearing capacity between structures and achieving the effect of edge installation and maintenance.

Understandably, the pressure generated by the offset of the roller body 30 is distributed through the cooperation between the mounting plate 321, mounting bracket 322, reinforcing plate 323, positioning bolt 324 and fixing bracket 325, thereby improving the load-bearing capacity of the device; In this embodiment, preferably, the fourth bearings 234 are identical in pairs and are symmetrically distributed on both sides of the surface of the connecting shaft 20; Specifically, the main housing 232 protects the first bevel gear 21, the second bevel gear 22, the first cylindrical gear 24, and the second cylindrical gear 25 through two identical fourth bearings 234; Understandably, during use, the inspection plate 233 can be opened to replace the first cylindrical gear 24 and the second cylindrical gear 25 according to the actual situation, thereby adjusting the speed ratio to meet different speed requirements.

[0018] In this embodiment, the variable speed transmission device for tillage compaction operation first connects the external power source to the power input shaft 26. When the power input shaft 26 rotates, it drives the first cylindrical gear 24 to rotate via the second cylindrical gear 25. This allows the second bevel gear 22 to drive the first bevel gear 21 within the main housing 232, in conjunction with the third bearing 231. The first bevel gear 21, through the connecting shaft 20, simultaneously drives two second transmission shafts 114 within the second housing 124, in conjunction with the second bearings 125.

The connecting spline shaft 10 drives another first drive shaft 111 to rotate within the flange connecting pipe 123. The first drive shaft 111, in conjunction with the first drive gear 112 and the second drive gear 113, drives the second drive shaft 114 to rotate. This, in turn, drives the connecting rod 31 and the roller 30 to rotate simultaneously. The pressure generated by the roller 30's offset is distributed through the cooperation between the mounting plate 321, mounting bracket 322, reinforcing plate 323, positioning bolt 324, and fixing bracket 325. During disassembly, the mounting bolt 326 is removed first, then the fixing bracket 325 with the positioning bolt 324 is removed, and finally the mounting bracket 322 with the reinforcing plate 323 is removed from the mounting plate 321 for quick maintenance. During use, the inspection plate 233 can be opened to replace the first cylindrical gear 24 and the second cylindrical gear 25, thereby adjusting the speed ratio to meet different speed requirements.
