Ear-hitting and blowing type hybrid paddy rice seed production pollination machine

Abstract

The invention discloses an ear-hitting and blowing type hybrid paddy rice seed production pollination machine. The machine comprises a frame walking assembly, an ear hitting assembly, a blowing assembly, and a controller. The ear hitting assembly comprises an ear hitting motor, a linear bearing, a left push rod, a right push rod, a left ear hitting rod, a right ear hitting rod, a support, and the like. One ends of the left ear hitting rod and the right ear hitting rod are respectively connected to two sides on the front end of the support through hinges. The other ends of the left ear hitting rod and the right ear hitting rod are respectively connected to one ends of the left push rod and the right push rod through hinges. The other ends of the left push rod and the right push rod are respectively connected on the linear bearing through hinges. The linear bearing is connected to a driving plate of the ear hitting motor through a connection rod. The blowing assembly comprises a main air pipe, branched air pipes, and a blower. A plurality of branched air pipes are respectively arranged on left and right sides of the main air pipe. An air outlet of the blower communicates with the center of the main air pipe. The whole machine is controlled by the controller. According to the invention, pollination is carried out under dual effects, which are mechanical impact and pneumatic force. Air flow speed, ear hitting amplitude, ear hitting frequency, and ear hitting height can be adjusted. Pollination is uniform, pollination effect is good, and work efficiency is high. The machine is suitable for seed production pollination of various paddy rice breeds.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an air-blow ear-hitting hybrid rice seed production and pollination machine. Background technique [0002] Pollination of hybrid rice is an important part of its production process, but the full flowering period of rice pollen is only 7-10 days, the flowering time is only 1.5-2 hours in a day, and the pollen life is only 4-5 minutes, so it must be completed within a limited time Pollination job. It can be seen that the pollination of hybrid rice is a job with strong technical requirements, high precision requirements and tight time requirements. At present, artificial assisted pollination in hybrid rice seed production includes manual and mechanical pollination. Artificial pollination is the most traditional pollination method, and the quality of pollination is high, but it is labor-intensive, low in production efficiency, and requires a lot of labor. It cannot be completed in a timely...
