Technical Field

[0001] The utility model relates to the field of garden management machines, and more specifically, to a transmission device for a garden management machine. Background Art

[0002] Garden management machines have the advantages of high working efficiency, small volume, and all-round functions. In particular, they are basically used in the work of trenching and soil cultivation. However, the groove shapes dug by the current garden management machines cannot meet the trapezoidal shape required in actual production. Therefore, secondary operations need to be carried out manually later, resulting in reduced efficiency and increased labor costs.

[0003] Therefore, it is necessary to provide a transmission device for a garden management machine to solve the above technical problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a transmission device for a garden management machine, which includes a transmission box, a driving shaft, a crown gear, a first transmission shaft, and a second transmission shaft. A universal coupling is arranged in the gear hole of the crown gear. The two ends of the universal coupling are fixedly connected to the first transmission shaft and the second transmission shaft respectively. The first transmission shaft and the second transmission shaft are both sleeved with second bearings, and the second bearings are fixedly arranged on the inner wall of the transmission box. The crown gear is meshed with a first bevel gear, and the first bevel gear is fixedly installed at the lower end of the driving shaft. A second bevel gear is installed at the upper end of the driving shaft, and the second bevel gear is meshed with a third bevel gear. The third bevel gear is fixedly connected to a driving shaft.

[0005] Preferably, the crown gear is inclined at a fixed angle, and the first transmission shaft and the second transmission shaft are both inclined downward at the inclination angle of the crown gear and are symmetric about the center of the universal coupling.

[0006] Preferably, both the first transmission shaft and the second transmission shaft are of hexagonal prism structure.

[0007] Preferably, a tapered roller bearing is arranged on the second bevel gear, and the tapered roller bearing is fixedly arranged in the inner cavity of the transmission box.

[0008] Preferably, a first bearing is arranged under the third bevel gear, and the first bearing is fixedly installed in the inner cavity of the transmission box.

[0009] Preferably, a limiting disc is arranged at the bottom of the crown gear, and the limiting disc is of disc structure.

[0010] Preferably, the outer ring of the second bearing is in a locked state, and the inner ring can rotate with the transmission shaft.

[0011] The technical solution of the utility model has at least the following beneficial effects:

[0012] Through the meshing structure of bevel gear 1 and crown gear, the transmission shaft rotates in an inverted V shape under the action of the universal coupling. After installing the tool at both ends of the transmission shaft, an inverted trapezoidal angle is formed, and the grooves reclaimed meet the actual production needs, reducing labor costs.

[0021] As Figure 1 shown, a transmission device of a garden management machine includes a transmission box 14, a driving shaft 6, a crown gear 4, a first transmission shaft 8 and a second transmission shaft 9. A universal coupling 5 is arranged in the gear hole of the crown gear 4. Both ends of the universal coupling 5 are fixedly connected to the first transmission shaft 8 and the second transmission shaft 9. The first transmission shaft 8 and the second transmission shaft 9 are both sleeved with second bearings 11, and the second bearings 11 are fixedly arranged on the inner wall of the transmission box 14. The crown gear 4 is meshed with a first bevel gear 1, and the first bevel gear 1 is fixedly installed at the lower end of the driving shaft 6. A second bevel gear 2 is installed at the upper end of the driving shaft 6. The second bevel gear 2 is meshed with a third bevel gear 3, and the third bevel gear 3 is fixedly connected to a driving shaft 7. The crown gear 4 is arranged at a fixed angle obliquely. The first transmission shaft 8 and the second transmission shaft 9 both incline downward at the inclination angle of the crown gear 4 and are centrosymmetric with respect to the center of the universal coupling 5. The first transmission shaft 8 and the second transmission shaft 9 are of hexagonal prism structure.

[0022] The working principle of the present utility model:

[0023] The rotation of the drive shaft 7 drives the bevel gear three 3 provided at the output end of the drive shaft 7. Through the meshing connection between the bevel gear three 3 and the bevel gear two 2 provided at the upper end of the drive shaft 6, the drive shaft 6 is driven to rotate. The drive shaft 6 can rotate fixedly through the bearing two 11 provided below the bevel gear two 2 and the tapered roller bearing 13 provided above the bevel gear one 1. The bevel gear one 1 provided at the lower end of the drive shaft 6 meshes with the crown gear 4 to drive the crown gear 4 to rotate. In order to prevent the crown gear 4 from moving under force, a limit disk 12 is provided at the bottom of the crown gear 4 for fixation. Since the gear hole of the crown gear 4 is provided with a universal coupling 5, the two ends of the universal coupling 5 are connected with a drive shaft one 8 and a drive shaft two 9, so that the drive shaft one 8 and the drive shaft two 9 are driven to rotate. Secondly, because the crown gear 4 is inclined, the drive shaft one 8 passes through the limit disk 12 and the crown gear 4 and is connected with the universal coupling 5. The drive shaft two 9 is symmetrically arranged with the drive shaft one 8 with the universal coupling 5 as the symmetry axis. Finally, the drive shaft one 8 and the drive shaft two 9 are stressed and rotated in an inverted V structure. In order to effectively improve the structural stability of the drive shaft one 8 and the drive shaft two 9, bearings one 10 are sleeved on both the drive shaft one 8 and the drive shaft two 9. The bearings one 10 are fixedly installed on the inner wall of the transmission case 14 and the outer rings of the bearings one 10 are in a locked state, and only the inner rings of the bearings one 10 rotate with the drive shaft one 8 and the drive shaft two 9 respectively. When the garden tillage machine performs ditching operations, the ditching tools are installed at the working ends of the drive shaft one 8 and the drive shaft two 9. When the tools rotate with the drive shaft, a trapezoidal cross-section is formed. With such a setting, the trenches dug out meet the actual production needs, improving the production efficiency and reducing the labor cost.

[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
