Description

Agricultural operation machine

Technical Field

The present utility model relates to agricultural work equipment.

Background

In order to meet various cultivation demands, various small-sized agricultural work machines designed according to the cultivation demands are on the market. Such as a mini-tiller for plowing, a film-laminating machine for film-laminating, a grass chopper for chopping grass, a ridger for ridging, etc. These agricultural work machines each generate power by an engine, and then transmit the power of the engine to a farming machine or a traveling apparatus through a transmission case having a power input mechanism, a speed change mechanism, and a power output mechanism, for performing a specific work operation.

Because of the different cultivation demands, there are operational differences (such as the number and variety of operating gears) between different agricultural working machines, it is difficult to realize different cultivation demands by changing cultivation devices or running devices, and only by designing transmission boxes with different functions.

These agricultural machines can be broadly classified into a single-drive-shaft output type and a multiple-drive-shaft output type according to the number of output shafts of the transmission structure. The agricultural working machine with single drive shaft output has the advantages of light weight and flexible operation, and is mainly suitable for rugged lands such as hills; the agricultural working machine with multiple driving shafts for output can be one driving shaft provided with a traveling device and the other driving shaft provided with a working device, so that the working efficiency can be greatly improved, but the agricultural working machine is suitable for being used on relatively flat lands due to relatively large weight and volume. Because single-drive-shaft output type agricultural working machines and multi-drive-shaft output type agricultural working machines are quite different in structure of a transmission case, manufacturing enterprises need to separately and independently produce and manufacture, and accordingly production cost is high.

The user needs to purchase two types (single-drive shaft output type and multi-drive shaft output type) of agricultural working machines according to the land type, and further needs to purchase agricultural working machines with different functions according to different cultivation requirements, so that the use cost of the user is very high, and popularization of the agricultural working machines is not facilitated.

Further, the upper box body is detachably connected with the lower box body. By adopting the arrangement, the lower box body is conveniently detached and replaced, so that the lower box body and the upper box body with different functions are conveniently realized, the transmission boxes with different functions are conveniently assembled, the whole transmission box is not required to be replaced, and the manufacturing cost is reduced.
