Abstract

The utility model discloses an automatic paying-out mechanism of a mower, which comprises a fixed line box connected with an output shaft, wherein, a line winding tray is arranged in the line box, a ratchet wheel is arranged at the external wall of the line winding tray, a plurality of ratchets are arranged on the ratchet wheel, a stopping block is pressed on the ratchets, an ear plate is arranged on the stopping block, the ear plate is sheathed on a column pin, the column pin is fixed on the line box along radius direction, and the column pin is also provided with a spring to press the stopping block to the ratchets. The utility model can realize automatic paying-out after secant abrasion to keep the secant that has reasonable working length to cause the mower to always be in optimal working state.

Description

The automatic payingoff mechanism of mower
The utility model relates to a kind of mower.
Mower is a kind of electric tool commonly used, and operation such as be mainly used to cut the grass on a lawn.The working head of mower mainly comprises by motor and mowing-apparatus two large divisions, its mowing-apparatus is divided into two kinds in cutterhead and line box again, cutterhead is to utilize blade to mow, the line box then is that the cutting force that utilizes secant to produce when high speed rotating is mowed, blade and secant all can be worn after using a period of time, blade abrasion can be changed later, can shorten after the secant wearing and tearing, could continue in the time of secant need being pulled out to active length in the line box to use, and the wearing and tearing of secant may be faster compared with blade, so when using with the line box as the mower of mowing-apparatus, to pull out secant continually, to guarantee the active length of secant, keep the optimum Working of mower, so just brought bigger trouble to operating personnel.
The purpose of this utility model is: a kind of automatic payingoff mechanism of mower is provided, and this mechanism can realize automatic unwrapping wire in secant wearing and tearing back, keeps the rational active length of secant, makes mower be in optimum Working all the time.
The technical solution of the utility model is: a kind of automatic payingoff mechanism of mower, comprise the line box that is connected and fixed with output shaft, be provided with wire spool in the line box, the outer wall of described wire spool is provided with ratchet, and ratchet is provided with some ratchets, presses on the ratchet to be provided with scotch, scotch is provided with otic placode, otic placode is enclosed within on the pin, and pin prolongs on the fixing online box of radial direction, also is provided with spring on the pin scotch is pressed to ratchet.
The further technical scheme of the utility model is: a kind of automatic payingoff mechanism of mower, comprise the line box that is connected and fixed with output shaft, be provided with wire spool in the line box, the outer wall of described wire spool is provided with ratchet, and ratchet is provided with some ratchets, presses on the ratchet to be provided with scotch, scotch is provided with otic placode, otic placode is enclosed within on the pin, and pin prolongs on the fixing online box of radial direction, also is provided with spring on the pin scotch is pressed to ratchet; The outer wall of described line box prolongs radial direction and is provided with column pin hole, pin is a screw, is fixed in the column pin hole by screw thread, and scotch is positioned at the line box, otic placode on the scotch is worn and is offered pilot hole on the connection box and be enclosed within on the pin, and the inwall of line box is provided with two gib blocks in the both sides that are positioned at scotch.
The utility model has the advantages that:
1. when secant shortens because of wearing and tearing, the mowing resistance reduces, rotating speed of motor will be accelerated, corresponding centrifugal force also increases, scotch overcomes spring under action of centrifugal force elastic force leaves ratchet, and wire spool will turn over a tooth automatically under the pulling of the centrifugal force of secant, thereby secant is lengthened.
2. the utility model is simple in structure, and is easy to operate, can realize automatic unwrapping wire, and secant keeps rational active length during work, makes mower be in optimum Working all the time.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Wherein: 1 output shaft; 2 line boxes; 3 wire spools; 4 ratchets; 5 ratchets; 6 scotch; 7 otic placodes; 8 pins; 9 springs; 10 column pin holes; 11 pilot holes; 12 gib blocks.
Embodiment: as shown in the figure, a kind of automatic payingoff mechanism of mower, comprise the line box [2] that is connected and fixed with output shaft [1], be provided with wire spool [3] in the line box [2], the outer wall of described wire spool [3] is provided with ratchet [4], ratchet [4] is provided with some ratchets [5], ratchet [5] is gone up to press and is provided with scotch [6], scotch [6] is provided with otic placode [7], otic placode [7] is enclosed within on the pin [8], pin [8] prolongs on the fixing online box [1] of radial direction, also is provided with spring [9] on the pin [8] scotch [6] is pressed to ratchet [5]; The outer wall of described line box [2] prolongs radial direction and is provided with column pin hole [10], pin [8] is a screw, be fixed in the column pin hole [10] by screw thread, scotch [6] is positioned at line box [2], otic placode [7] on the scotch [6] is worn and is offered pilot hole [11] on the connection box [2] and be enclosed within on the pin [8], and the inwall of line box [2] is provided with two gib blocks [12] in the both sides that are positioned at scotch [6].
When secant shortens because of wearing and tearing, the mowing resistance reduces, rotating speed of motor will be accelerated, corresponding centrifugal force also increases, scotch [6] overcomes spring [9] under action of centrifugal force elastic force leaves ratchet [5], and wire spool [2] will turn over a tooth automatically under the pulling of the centrifugal force of secant, thereby secant is lengthened; The utility model is simple in structure, and is easy to operate, can realize automatic unwrapping wire, and secant keeps rational active length during work, makes mower be in optimum Working all the time.
