Description

Spike and stem harvesting type maize picker main drive shaft fixing device

Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to a fixing device for a main transmission shaft of a spike-stalk harvesting type corn harvester.

Background

China has wide corn planting range and large corn planting area, but the corn machine sowing level in China only reaches 60 percent at present, and the machine harvesting level is only 6.8 percent, so the machine harvesting level becomes the bottleneck restricting the whole-course mechanization of corn, and especially the manual corn harvesting and straw treatment become the most heavy physical labor of farmers in northern areas. Because the manual harvesting cost is high, farmers often burn the corn straws, and the environmental pollution is serious. The ear-stalk harvesting is proposed for solving the air pollution caused by stalk burning and the requirement of developing animal husbandry, namely, the corn ears are harvested while the stalks are cut and collected or returned to the field or not crushed and laid. Foreign corn is mostly planted in one season in one year, and the harvested corn is returned to the field, and is deeply ploughed into the soil to fertilizer the field in a slack winter condition. In the wheat and corn twice-a-year region of China, with the development of industrial fuels, straws which are used as main fuels in rural areas in Xiri become waste which pollutes air by field incineration, and the rapidly-developing animal husbandry needs a large amount of feed. Therefore, the development of the ear-stalk harvesting type corn harvester has important significance.

However, since the corn harvester needs to be equipped with auxiliary machinery such as a corn root-digging and crushing device for different working purposes, or the required equipment and operation speed are changed at any time when the humidity of the corn stalks is different, more changing requirements are required to be provided for the transmission device.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a ear of grain stem and reap type maize picker main drive shaft fixing device, includes the main shaft, the main shaft passes through the bearing and sets up in the bearing bracket, the top of bearing bracket is provided with the recess, the opening that the recess set up along main shaft axial direction for the bearing bracket, be provided with the bearing frame that is used for holding the bearing in the recess, the bearing bracket can be dismantled and be provided with and be used for the shutoff the connecting plate of recess, the connecting plate is including being located the clamp plate of hugging closely bearing upper portion setting and being located the fixed plate that the clamp plate both ends are connected with the bearing bracket.

As a further development of the utility model, the spindle is provided with a plurality of transmission wheels.

As a further improvement of the utility model, the transmission wheel is a belt pulley or a chain wheel.

As a further improvement of the utility model, the connecting plate is connected with the bearing bracket through a bolt.

As a further improvement of the utility model, the bearing is an outer spherical bearing.

As a further improvement of the utility model, the side face of the bearing is provided with a bearing cover for sealing.

The utility model has the beneficial effects that:

according to the utility model, the main shaft supporting position is arranged in the groove on the bearing frame, and the main shaft is fixed by adopting the detachable connecting plate, so that the main shaft and the bearing frame are more convenient to detach and mount.
