Valley harrow

Abstract

The invention discloses a grain harrow which is more complete in function, is higher in working efficiency and is more convenient to use. The grain harrow comprises a harrow handle, a harrow head, a first bolt, a second bolt, a first nut, a second nut and a scraper, wherein first harrow teeth are arranged at one side of the harrow head at the same interval; second harrow teeth are arranged at the other side of the harrow head at the same interval; interval width of the first harrow teeth is greater than that of the second harrow teeth; the harrow handle passes through a harrow handle displacement hole of the scraper, and is fixedly arranged in a harrow handle sleeve joint hole of the harrow head; the first bolt sequentially passes through a first bolt hole of the harrow head and a first bolt displacement hole of the scraper, and is locked through the first nut; and the second bolt sequentially passes through a second bolt hole of the harrow head and a second bolt displacement hole of the scraper, and is locked through the second nut.

Description

technical field [0001] The invention relates to a grain tumbling device, in particular to a grain rake. Background technique [0002] After the farmers harvest the rice grains from the farmland, because the moisture content of the freshly harvested rice grains is high, it is inconvenient to store them, so they need to be dried on the drying ground. During the drying process, the rice is turned over with a rake, thinned and filtered, and the rice is scraped with a rake. A traditional grain rake consists of a rake handle and a rake head, the rake head is vertically connected to one end of the rake handle, and the rake head is provided with rake teeth. The traditional scraping rake consists of a rake handle and a rake plate, and the rake plate is vertically connected to one end of the rake handle. [0003] In actual use, use a rake with looser teeth to filter the rice coarsely, then use a rake with denser teeth to filter the rice finely, and use a rake with shorter teeth to t...

AI Technical Summary

Problems solved by technology

[0003] In actual use, use a rake with looser teeth to filter the rice coarsely, then use a rake with denser teeth to filter the rice finely, and use a rake with shorter teeth to thin the rice. Use a rake with long rake teeth to turn the rice in the sun, and use a rake to scrape the rice into a pile, which leads to the need for multiple rakes and rakes to meet the needs, so the traditional rice rake has a simple structure and a single function , the work efficiency is not high, and it is inconvenient to use
