Abstract

The utility model discloses a double-blade flail type mowing blade, which comprises a blade body, wherein one side of the blade body is provided with a flat blade which is a linear cutting edge; the top end of the cutter body is provided with a tooth blade. The traditional mower blade generally adopts a single flat blade structure, the problems of blade breakage, blunt blade and the like easily occur when the blade contacts with shrubs and other hard plants for a long time, and the service life of the blade is greatly shortened. The utility model discloses a serrated edge, flat sword twolip combination let the serrated edge at first with harder plants such as shrub contact and saw cut, the softer weeds that follows just contact with the flat sword and are cut off to prolonged the life of flat sword, the serrated edge is longer owing to adopt the mode work of saw cutting simultaneously.

Description

Double-edge flail knife type mowing blade

Technical Field

The utility model relates to an agricultural lawn mower field, concretely relates to twolip combination flail knife formula mowing blade.

Background

In recent years, with the further popularization of green ecological planting modes, operation modes of plant protection management without herbicide application and clear tillage, such as mechanical weeding modes using a mower, have gained more and more acceptance. The lawn mowers can be divided into a hob type, a rotary cutter type, a side hanging type and a flail type according to the mowing mode. The flail mower has the advantages of high working efficiency, strong terrain adaptability and the like, and the service life of the cutter is closely related to the factors such as the material, the type of the cut plants, the quantity of the lawn sundries and the like and the structure of the blade.

The blade of the existing flail mower generally adopts a single-face flat blade structure or a double-face flat blade structure which is simple in structure and easy to manufacture and other variant structures, mainly focuses on realizing the mowing function, and has less consideration on the aspects of blade edge protection, smooth grass cutting elimination and the like in the structure.

The traditional mower blade generally adopts a single flat blade structure, and is easy to cause the damage of a rolling blade and a tipping blade when encountering hard plants such as shrubs and the like, thereby influencing the operation effect. In addition, due to the fact that no grass discharging structure is arranged, when the humidity of the grassland is too high and the grass is too dense, grass discharging is not smooth easily.

SUMMERY OF THE UTILITY MODEL

In view of the above situation, the present invention is directed to a double-edge flail mower blade, which can avoid the damage of the blade when the blade touches hard plants such as shrubs and can work in complicated land.

The utility model discloses the concrete technical scheme who takes is:

a double-blade flail knife type mowing blade comprises a knife body, wherein a flat blade is arranged on one side of the knife body, and the flat blade is a linear cutting edge; the top end of the cutter body is provided with a tooth blade.

In order to better realize the utility model discloses, the tooth sword is the arc and arranges.

For better realization the utility model discloses, be equipped with on the cutter body and get rid of the grass baffle, get rid of the grass baffle and set up from low to high in the cutter body upper horizontal direction, one side that is equipped with the flat sword is low, and is less than the minimum of flat sword.

For better realization the utility model discloses, it is the arc to get rid of the grass baffle.

For better realization the utility model discloses, the cutter body lower extreme is equipped with the mounting hole, and the cutter body articulates together with the lawn mower connecting pin through this mounting hole.

The utility model has the advantages that: the traditional mower blade generally adopts a single flat blade structure, the problems of blade breakage, blunt blade and the like easily occur when the blade contacts with shrubs and other hard plants for a long time, and the service life of the blade is greatly shortened. The utility model discloses a serrated edge, flat sword twolip combination let the serrated edge at first with harder plants such as shrub contact and saw cut, the softer weeds that follows just contact with the flat sword and are cut off to prolonged the life of flat sword, the serrated edge is longer owing to adopt the mode work of saw cutting simultaneously. The traditional mower blade is easy to cause grass blockage due to no grass discharge structure, so that the blade and accumulated weeds are repeatedly cut, and the service life is shortened. The utility model adds the grass throwing baffle, which can avoid grass blocking and smooth grass discharge during operation, improve grass cutting efficiency and reduce blade abrasion; the blade adopts articulated formula mounting hole, and the cutter body bumps hard things such as stone, hard soil and can automatic skew dodge, plays the effect of protection blade.

Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1, the present embodiment provides a double-edged flail mowing blade, as shown in fig. 1, which comprises a blade body [006], a tooth blade [001], a flat blade [002], a flail baffle [004], a mounting hole [005], and the like. Wherein, the flat blade [002] is positioned at the left side of the cutter body [006] and is a linear cutting edge; the tooth blade [001] is positioned at the top end of the cutter body [006] and is arranged in an arc shape; the mounting hole [005] is positioned at the lower end of the cutter body [006], the mounting hole [005] is used for being hinged with a connecting pin of the mower, and the blade can freely move left and right; the grass throwing baffle plate [004] is arc-shaped and is erected on the top surface of the cutter body [006], the left end is low and the right end is high, the left end is lower than the lowest point of the flat blade [002] and is positioned on the mounting hole [005], and the grass throwing baffle plate [004] is designed into an arc shape so as to reduce the friction force with weeds, facilitate the rapid throwing of the weeds, avoid grass breaking and blocking to ensure smooth grass discharge during operation, improve the grass cutting efficiency and reduce the abrasion of blades. The rotation direction [003] in the figure is counterclockwise rotation (clockwise rotation if the flat blade is disposed on the right side); when the blade rotates along with the mower, the blade is radially unfolded under the action of centrifugal force, the tooth blade [001] is firstly contacted with harder plants such as shrubs and the like and sawn, then softer plants such as weeds and the like are contacted with the flat blade [002] and cut, and the service life of the flat blade is prevented from being shortened due to excessive contact with the harder plants. The blade is hinged with the connecting pin of the mower, and can automatically deviate and avoid when meeting hard objects such as stones, soil blocks and the like, so that the effect of protecting the blade is achieved. The top surface of the cutter body is provided with a grass throwing baffle plate [004], so that the thrown and cut weeds can be discharged in time during the grass cutting operation, and the grass can be smoothly discharged during the operation due to the congestion.

Although the embodiments have been described, once the basic inventive concept is known, other changes and modifications can be made to the embodiments by those skilled in the art, so that the above embodiments are only examples of the present invention, and not intended to limit the scope of the present invention, and all the modifications of the equivalent structure or equivalent flow path using the contents of the specification and the drawings of the present invention, or directly or indirectly using other related technical fields are also included in the scope of the present invention.
