Mud scraping mechanism of drill seeder pressing roller

Abstract

The invention discloses a mud scraping mechanism of a drill seeder pressing roller. The mud scraping mechanism comprises a pressing roller, wherein a main shaft is arranged in the middle of the pressing roller; an outer protection plate is arranged on the outer side of the pressing roller; the outer protection plate is connected with two ends of the main shaft through bearings; more than four groups of first mud outlet grooves are distributed in equal distances inside the outer protection plate; arc-shaped mud scraping plates are connected with the middle positions inside the first mud outletgrooves through rotating shafts; a mud scraping rod is connected with one end far away from the outer protection plate, of a connecting rod, through a rotating shaft. Due to adoption of three mud scraping mechanisms, namely the mud scraping plate, the mud scraping roller and the arc-shaped mud scraping plate, the mud scraping effect can be greatly improved; due to adoption of the outer protectionplate on the outer side of the pressing roller, mud splashing can be prevented, and in addition, the pressing roller can be protected; due to design of a first mud outlet groove and a second mud outlet groove, soil can be greatly conveniently scrapped off from the pressing roller; the arc-shaped mud scraping plate can be driven by a first electronic telescopic rod in a telescopic manner to rotatearound a sliding plate through the rotating shaft, and the mud scraping angel can be conveniently adjusted.

Description

technical field [0001] The invention relates to the technical field of seed drills, in particular to a mud scraping mechanism for a pressure roller of a seed drill. Background technique [0002] At present, the strip seeder used by farmers is generally modified by adding a seed fertilizer box on the basis of the rotary tiller, and the pressure roller is used to drive the rotation of the seed shaft and fertilizer shaft during the field pressure, so as to realize seed and fertilizer discharge. But because sometimes the field is rotten, a lot of mud is stuck on the trimming roller in operation, which affects cultivation. Therefore, a mud scraping mechanism is arranged on the back and upper side of the trimming roller to scrape off the mud. The structure is complex, the mud scraping effect is not good, and the mud splashing cannot be prevented. For example, the patent application publication number 201720045729.X discloses a mud scraping mechanism for the pressure roller of the ...

But because sometimes the field is rotten, a lot of mud is stuck on the trimming roller in operation, which affects cultivation. Therefore, a mud scraping mechanism is arranged on the back and upper side of the trimming roller to scrape off the mud. The structure is complex, the mud scraping effect is not good, and the mud splashing cannot be prevented. For example, the patent application publication number 201720045729.X discloses a mud scraping mechanism for the pressure roller of the seed drill. The roller is connected with the seed shaft or the fertilizer shaft that goes out of the seed fertilizer box. There is a mud scraping mechanism on the rear and upper part of the pressure roller. There is a slatted scraper, but the above patents cannot improve the mud scraping effect during use, and cannot prevent mud from splashing
