An intermediate transmission device for agricultural machinery

Abstract

The present invention discloses an intermediate transmission device of agricultural farming machinery. The device comprises a shell, the left side and the right side of the interior of the shell are connected with a rotation shaft by bearings; a pulley is arranged at the side, extending out of the shell, of the left end of the rotation shaft, and the pulley is connected with an external power unit by a belt; the middle side of the rotation shaft is provided with cams, and the upper end of each cam is connected with a supporting bar by a clamping component; the lower end of the side of each supporting bar is provided with a ring-shaped baffle, and the middle of the side of each supporting bar is sleeved with a first spring, and the bottom of each first spring is fixedly connected with the upper surface of the corresponding ring-shaped baffle; and the top of the interior of the shell is provided with a mounting panel. The intermediate transmission device of the agricultural farming machinery is simple in structure and low in cost. The external power unit drives the pulley to rotate by the belt, multi-channel sowing is realized by the transmission device, and meanwhile the seed outflow frequency is controlled, the waste of the seeds is reduced, and the human and material resources are saved. Meanwhile, multi channel simultaneous sowing is performing, the sowing speed can be ensured and time is saved.

Description

technical field [0001] The invention relates to the technical field of agricultural farming, in particular to an intermediate transmission device for agricultural farming machinery. Background technique [0002] With the continuous development of my country's economic construction, earth-shaking changes have taken place in the field of agricultural production in our country. The agricultural machinery has also changed from the original simple manual operation method to a multi-functional, multi-structure semi-automatic operation method. There are a lot of improvements and innovations, but there are still some deficiencies. When the existing agricultural machinery is working, due to the simple structure of the transmission device, only one rotation torque can be output through a single shaft, and this simple transmission device has caused During farming and sowing, the seeding speed is greatly reduced, resulting in a waste of manpower and material resources. If multiple rotatio...

[0002] With the continuous development of my country's economic construction, earth-shaking changes have taken place in the field of agricultural production in our country. The agricultural machinery has also changed from the original simple manual operation method to a multi-functional, multi-structure semi-automatic operation method. There are a lot of improvements and innovations, but there are still some deficiencies. When the existing agricultural machinery is working, due to the simple structure of the transmission device, only one rotation torque can be output through a single shaft, and this simple transmission device has caused When farming and sowing, the seeding speed is greatly reduced, resulting in a waste of manpower and material resources. If multiple rotations are required to output at the same time, multiple shafts and input devices are required, which increases the production cost of the device and makes the device more complicated.
