[0001] The invention relates to the field of gear processing, and in particular to a heat treatment device for a transmission gear of a seed drill. Background Art

[0002] As an important mechanical transmission element, gears play an irreplaceable role in various fields. With the continuous advancement of science and technology and the continuous expansion of applications, gear technology will continue to develop and improve. Gears have teeth on the rim and can continuously mesh to transmit motion and power. Gears are widely used in seed drills. During the processing of gears, heat treatment is often required to improve the hardness of the gears.

[0003] However, in order to reduce production costs, the existing heat treatment facilities mostly recycle the quenching liquid when processing gears. Due to the recycling of the quenching liquid, some impurities will be contained in the quenching liquid, causing the subsequent quenching liquid to block the water spray holes when it is sprayed out to cool the gears, resulting in a decrease in the amount of quenching liquid sprayed, resulting in insufficient cooling of the gears and poor hardness of the processed gears.
