Problems solved by technology

[0004] However, when using a rotary tiller, the port of the rotary tiller shaft is connected to the rotary tiller body. If the connection is entangled by weeds, it will affect the rotation of the rotary tiller shaft, and even cause the rotary tiller shaft to be damaged. It cannot be rotated, which affects the normal use of the rotary tiller. Although there is an operation that can scrape the blade shaft, it can only be scraped

Abstract

The invention discloses a grass scraping device for preventing grass winding of a rotary cultivator cutter shaft. The grass scraping device comprises two arc-shaped plates, wherein the arc-shaped plates are connected through a first connecting mechanism; a sliding groove is formed in the middle of the outer side of each arc-shaped plate; the bottom end of a sliding rod is located in the sliding groove and matched with the sliding groove; a fixed box is fixedly connected to the top of the sliding rod; a first spring is arranged in the fixed box; movable plates are fixedly connected to the two sides of the first spring; blades are fixedly connected to the sides, away from the first spring, of the movable plates; a plurality of vertical weeding knives are fixedly connected to the two sides ofthe bottom of the fixed box, and transverse weeding knives are connected between the vertical weeding knives; a fixing mechanism is arranged at the top of the fixed box and located on one side of a movable opening; a first sleeve is arranged on one side of each arc-shaped plate; and the first sleeve is fixedly connected with a flange plate. The grass scraping device has the beneficial effects that weeds can be cut off before the weeds are wound on the cutter shaft, and the possibility that the weeds are wound on the cutter shaft is reduced.

Description

technical field [0001] The invention relates to the technical field of rotary tillers, in particular to a grass scraping device for preventing the cutter shaft of the rotary tiller from being entangled with grass. Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing. At the same time, it can chop up the root stubble buried below the surface, which is convenient for the seeder to operate and provides a good seed bed for later sowing. [0003] A driven soil tillage machine with rotating cutter teeth as the working part, also known as a rotary tiller. According to the configuration of the rotary tiller shaft, it is divided into two types: horizontal axis type and vertical axis type. The horizontal-axis rotary tiller with the knife shaft horizontally placed is widely used, and it has a stro...
