Description

Technical Field

[0001] This utility model relates to the field of rotary tiller technology, specifically to a rotary tiller toothed rake shaft transmission device. Background Technology

[0002] A rotary tiller is an agricultural tillage machine mainly used for soil pretreatment before crop planting. Driven by a power source, its rotating working parts (such as rakes and rake wheels) cut, break, turn, and level the surface soil, thoroughly mixing compacted soil, crop residues (such as straw and root stubble) with the topsoil to form a loose, fine, and level tillage layer. This creates suitable soil conditions for sowing, seedling raising, or transplanting. It is typically connected to tractors or other power machinery via three-point suspension, traction, or direct mounting. The rotation of the working parts is driven by the power output from the tractor (such as the power take-off shaft). Widely used in tillage operations on plains, hills, and other terrains, it is suitable for planting various crops such as wheat, corn, rice, and vegetables. It is one of the core pieces of equipment in modern agricultural production for achieving efficient tillage and reducing manual labor intensity; therefore, a rotary tiller toothed rake shaft transmission device is required.

[0003] The existing transmission structure is relatively complex, usually using multi-stage gear transmission. This not only makes installation and disassembly inconvenient, but also causes severe wear between gears under long-term high-load operation, resulting in reduced transmission efficiency and affecting the working effect of the rotary tiller.

[0006] A transmission assembly is positioned on the side of the stabilizer;

[0007] The transmission assembly includes a transmission mechanism disposed on the side of the stabilizing support;

[0008] An auxiliary mechanism is provided on the side of the stabilizing support.

[0009] Preferably, a rectangular block is fixedly installed on the side wall of the stabilizing bracket, and a reinforcing member is fixedly installed on the side wall of the rectangular block.

[0010] Preferably, the auxiliary mechanism includes a long plate, one end of which is fixedly connected to the side wall of the reinforcing member, a horizontal plate is fixedly installed at the bottom of the long plate, a side plate is fixedly installed at the bottom of the horizontal plate, and a protective shell is fixedly installed on the side wall of the side plate.

[0014] Preferably, there are multiple reinforcing members, all of which are of the same shape and size, and are distributed equidistantly on the sidewalls of the rectangular block.

[0015] This utility model provides a transmission device for the toothed rake shaft system of a rotary tiller. It has the following beneficial effects:

[0016] (1) When the operator uses the device, the operator can turn on the motor. The motor drives the rotating rod one to rotate through the rotating shaft at the output end. The rotating rod one drives the driving wheel to rotate. The driving wheel drives the driven wheel to rotate under the action of the belt. The driven wheel drives the rake to rotate under the action of the rotating rod two. The rake, while the rotating rod one rotates, also drives the gear one to rotate. The gear one drives the gear two to rotate, which can drive other parts to transmit power.

[0017] (2) The present invention can improve the stability between the support and the horizontal plate by using the long plate. A side plate is set at the bottom of the horizontal plate. The side plate can support and limit the position of the protective shell. The protective shell can protect the side walls of gear one and gear two. Attached Figure Description
