Description

Grass splashing prevention device at front part of mower

Technical Field

The invention belongs to the field of suspended mowers, and particularly relates to a grass splashing prevention device at the front part of a mower.

Background

A lawn mower is a tool used in agricultural or household machinery to remove weeds or to trim grass. The mower is suspended behind the tractor through three points, provides power through the transmission shaft of the tractor, utilizes crossed blades to mow, and is widely applied to fields, gardens, golf courses or lawn greening places. The lawn mower is at the in-process of mowing, especially flail knife formula lawn mower, and the grass that cuts can splash everywhere, consequently sets up in the lawn mower front portion and keeps off the grass mechanism, and current lawn mower front portion prevents that the grass splashes the device like the published flail knife formula lawn mower that "an integral type hung" that china utility model patent CN209283732U discloses, sets up the baffle in the frame front portion, and the baffle is multiunit metal separation blade, articulates on the bracing piece, and rotatable ground soil block of avoiding effectively prevents ruderal splash everywhere. However, in the actual use process, the retaining sheet is easy to be blocked and is easy to deform when encountering hard solids such as stones and the like, thereby influencing the grass retaining effect. When the support rod is replaced, the whole support rod needs to be detached, the blocking piece on one side is removed, and the deformed blocking piece is removed. Some companies change to hard rubber materials, but the wear resistance is reduced and the service life is short.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a grass splashing prevention device at the front part of a mower, which is simple to mount and dismount, flexibly avoids hard sundries and effectively prevents weeds from splashing.

In order to achieve the aim, the invention provides a grass splashing prevention device at the front part of a mower, which comprises a base plate, a chain and a stop lever,

the base plate is arranged at the front side of the bottom of the machine frame,

the chain string is formed by combining a plurality of chain rings which are buckled with each other,

the chain cluster has a plurality ofly, and vertical the hanging is in base plate bottom, the base plate has a plurality of rectangular form breachs that parallel, and the chain at chain cluster top inserts the breach, the pin inserts the intra-annular of top chain and prevents the chain cluster pine takes off.

Further, the chain string is composed of 5 chains, and the gap between the two chain strings at the closest part is within 0.3 cm.

Further, the width of the chain gap of the chain lock string is 0.8-1.5 cm.

Further, the chain of the chain string is made of stainless steel materials, subjected to heat treatment, HRC 45-50, and coated with an anti-rust coating on the surface.

Furthermore, the stop lever can be many, also can be one, and both ends are screwed with the nut anticreep.

Furthermore, two groups of lock chains are arranged in series in the front part of the frame.

The invention has the beneficial effects that:

the grass splashing prevention device at the front part of the mower is formed by combining a plurality of groups of chain chains in parallel, and the chain chains have large movement allowable space, are flexible in avoiding solid obstacles and flexible in installation, and are suitable for reforming the existing suspension type mower.

Detailed Description

The details of the present invention are described below with reference to the accompanying drawings and specific embodiments.

As shown in figure 3, the grass splash preventing device at the front part of the mower comprises a base plate 1, a chain and a stop lever 4,

as shown in fig. 1, the base plate 1 is installed at the front side of the bottom of the housing 2,

as shown in fig. 2, the chain lock string 3 is formed by combining a plurality of chain lock rings, the rings are buckled with each other,

the lock chain cluster 3 has a plurality ofly, and vertical the hanging is in base plate 1 bottom, base plate 1 has a plurality of rectangular form breach 5 that parallel, and the chain at 3 tops of lock chain cluster inserts breach 5, the intra-annular of fender rod 4 insertion top chain prevents 3 pine of lock chain cluster take off.

In practical application, the chain string 3 is composed of 5 chains, and the gap between the two chain strings 3 at the nearest part is within 0.3 cm.

In practical application, the width of the chain gap of the chain string 3 is 0.8-1.5 cm.

In practical application, the chain of the chain string 3 is made of stainless steel material, and is subjected to heat treatment, HRC 45-50, and the surface of the chain is coated with an antirust coating.

In practical application, the stop lever 4 can be provided with a plurality of stop levers or one stop lever, and nuts are screwed at two ends of the stop lever to prevent the stop lever from falling off.
