Technical Field:

[0001] The utility model relates to the field of agricultural machinery, specifically to a drive module of a farming machine. Background Art:

[0002] Currently, large agricultural farming machines mainly consist of two parts: a locomotive and a farming device. The locomotive generally uses a tractor driven by a diesel internal combustion engine. The farming device is installed on the locomotive or towed by the locomotive to realize operations in the farmland. With the continuous development of new energy technologies, currently, small and medium-sized farming machines on the market have gradually started to use electric tractors as the power devices of the farming machines. Compared with traditional tractors, electric tractors not only save energy and are environmentally friendly, but also have the advantages of smaller volume, lower noise, lower maintenance costs, simple operation (can be unmanned), and high reliability, and are increasingly favored by the market.

[0003] Currently, farming machines using electric tractors on the market are usually in an unmanned mode and work by remotely operating the farming machine. For example, a kind of agricultural rotary tiller with the Chinese patent publication number: CN 114271046 A. This patent includes: a towing locomotive 1, a rotary tilling mechanism 2, a towing mechanism 30 for connecting the towing locomotive 1 and the rotary tilling mechanism 2, a flipping driving member 6, and a supporting mechanism 8. Since the drive module of the towing locomotive 1 generally uses a motor directly connected to the input shaft of the gearbox, although this method can make the structure of the drive module more compact, when the load is too large, it is easy to burn out the drive motor, and this structure will increase the wear of the gears in the gearbox, resulting in a reduction in the service life of the drive module.

[0004] In view of this, the inventor of the present invention proposes the following technical solutions. Summary of the Utility Model:

[0011] After adopting the above technical solution, the present utility model has the following beneficial effects compared with the prior art: In the present utility model, a transmission belt pulley set is disposed between the traveling motor and the speed change gearbox to connect and transmit power.

In this embodiment, a protective cover plate D110 is arranged at the bottom of the box body D11. The box body D11 is protected by the protective cover plate D110 to reduce the damage caused by the bottom of the variable speed gearbox D1 rubbing against the ground during driving. At the same time, the protective cover plate D110 is arc-shaped, which can reduce the impact generated by the variable speed gearbox D1 rubbing against the soil during driving, and can avoid the direct contact and wear of the box body D11 with the ground, thereby prolonging the service life of the variable speed gearbox D1.

[0038] In summary, when the utility model works, the tractor 1 drives the rotary tillage mechanism 2 to move. When tilling is required, the rotary tillage mechanism 2 is lowered through the lifting bracket mechanism 3, so that the left rotary blade group 24 and the right rotary blade group 25 of the rotary tillage mechanism 2 are inserted into the soil. Driven by the rotary blade motor 22, the left rotary blade group 24 and the right rotary blade group 25 start to work, and at the same time, the tractor 1 pulls the rotary tillage mechanism 2 forward, thereby realizing tilling; further, when an agricultural mechanism needs to be replaced, for example, a weeding machine, it is necessary to first lift the rotary tillage mechanism 2 through the lifting bracket mechanism 3, loosen the bolts or pins between the rotary tillage mechanism 2 and the snap-fastening mounting frame 4, and then lift the rotary tillage mechanism 2 upward manually or with the help of a crane and remove it from the snap-fastening mounting frame 4. Of course, in order to facilitate the removal of the rotary tillage mechanism 2, the rotary tillage mechanism 2 can also be pulled out of the soil and placed on the ground. After removing the locking bolts or pins, it is swung downward through the lifting bracket mechanism 3 to disengage from the rotary tillage mechanism 2, and finally the weeding machine is installed on the snap-fastening mounting frame 4 to complete the replacement of the agricultural mechanism.
