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 when the weeds are wrapped around the blade shaft. For thinner weeds, it may It cannot be removed, causing it to be entangled on the cutter shaft. In addition, for thicker weeds, it may not be possible to remove due to the limitation of the blade, so that the rotary tiller cutter shaft cannot avoid weeds being entangled on the cutter shaft, which affects the use of the cutter shaft. resulting in the failure of the mowing device

Abstract

The invention discloses a grass scraping device for preventing the blade shaft of a rotary cultivator from wrapping grass, comprising two arc-shaped plates. There is a chute, the bottom end of the sliding rod is located in the chute and matched with the chute, the top of the sliding rod is fixedly connected with a fixed box, and the interior of the fixed box is provided with a spring 1, the Two sides of the first spring are fixedly connected with movable plates, the side of the movable plate away from the first spring is fixedly connected with blades, and two sides of the bottom of the fixed box are fixedly connected with a plurality of vertical weeding knives, the vertical weeding knives are fixedly connected. A transverse weeding knife is connected between them, a fixing mechanism is provided on the top of the fixed box and on the side of the movable opening, and a sleeve is provided on one side of the arc-shaped plate. Orchid plate. Beneficial effect: The weeds can be removed before the weeds are wrapped around the cutter shaft, and the possibility of the weeds being entangled on the cutter shaft is reduced.

Description

technical field [0001] The invention relates to the technical field of rotary cultivators, in particular to a grass scraping device for preventing the blade shaft of the rotary cultivator from wrapping grass. Background technique [0002] Rotary cultivator is a cultivating machine matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil crushing ability and flat surface after ploughing. [0003] Driven soil tillage machinery with rotating cutter teeth as working parts, also known as 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 axis horizontally placed is widely used, and it has a strong ability to crush soil. One operation can make the soil finely crushed, the soil and fertilizer are evenly mixed, and the ground is flat, so as to achieve dry land sowing or padd...
