[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.
Referring to fig. 1-3, the present invention provides a backpack type field pavement marker, comprising:
a back barrel 1 for containing lime or fertilizer, wherein the top of the back barrel is provided with a cover 2 which can be opened and closed;
two braces 3 arranged at one side of the back barrel 1;
the two scribing tubes 4 are communicated with the bottom of the back barrel 1, spiral blades 5 are axially arranged at the joint of the end parts of the two scribing tubes 4 and the back barrel, at least one conical powder outlet tube 6 extends from one end of each scribing tube 4, which is far away from the back barrel 1, the small end of each powder outlet tube 6 faces to one side, which is far away from the back barrel 1, the end parts of the spiral blades 5 are not inserted into the powder outlet tubes 6, a handle 7 is obliquely extended from the outer wall of each scribing tube 4, and the handle 7 is obliquely arranged towards the side of the back barrel 1 from the scribing tube 4;
locate and draw the line pipe 4 outside and be used for providing two motors 8 of power for helical blade 5, its pivot with be connected with helical blade 5 one end, be equipped with the switch (not marking in the picture) that is used for controlling the 8 rotational speeds of motor on the handle 7, can adjust motor speed through this switch, realized the control of helical blade rotational speed to can reach the control of ash discharge amount or fertilizer discharge amount, if motor speed is fast, then ash discharge amount or fertilizer discharge amount are big, if motor speed is slow, then ash discharge amount or fertilizer discharge amount are little.
Particularly, if the handle is vertically arranged on the outer side of the scribing tube, the end of the powder discharging tube is pressed downwards by hand force when the chalk is used, or the elbow is required to be bent, so that the hand or the elbow is uncomfortable after the chalk is operated for a long time, and therefore the included angle between the handle 7 and the scribing tube 4 is 45-60 degrees; due to the design, when in line drawing, the user only needs to put the arms on the line drawing pipe at will, discomfort of hands or elbows caused by long-time use is avoided, if the angle is too large, the effect of relaxing and relieving the discomfort of the hands or elbows is avoided, if the angle is too small, the wrist needs to be inclined, the discomfort of the wrist is increased, and therefore the angle is designed to be 45-60 degrees, and the comfort of the operator in use is greatly improved.
Particularly, a filter screen 9 is arranged on one side of the inner wall of the back barrel 1 close to the cover 2; so design, the filter screen can block massive lime on the net, when using, can not make helical blade die by the massive lime card, even there is the fritter lime, also can be smashed under helical blade's rotation, when having improved work efficiency indirectly improved motor and helical blade's life.
Particularly, if the spiral blade is in a non-working state, lime is accumulated at the end part of the scribing tube, only part of the lime is in contact with the spiral blade at the moment, and the lime can be pushed to the end part of the discharge hole after the spiral blade starts working, so that the working time is prolonged, and the lime can not be pushed well possibly because the spiral blade is not in contact with the lime enough, so that two semicircular grooves 10 are formed in the bottom of the barrel back 1, one end, close to the strap 3, of each semicircular groove 10 is communicated with the scribing tube 4, and the spiral blade 5 is inserted into the semicircular grooves 10 and then is connected with the rotating shaft of the motor 8; so design, make the helical blade in the recess direct and lime contact, after work, along with helical blade's rotation, it is intraductal that lime that is located helical blade just can be quick is impeld the line to be drawn, and the lime of being convenient for advances along with helical blade's rotation to quick effectual advancing lime discharge gate, thereby be convenient for quick effectual line.
Particularly, the distance between the semicircular groove 10 and the edge of the spiral blade 5 is 1cm, and the distance between the edge of the spiral blade 5 and the inner wall of the scribing tube 4 is 0.5 cm; so design, can effectually prevent friction between helical blade and semicircular groove, the marking off pipe to its life has been improved, simultaneously, lime that prevents that can be fine flows along helical blade and the space between the marking off pipe, avoids causing the waste.
In particular, an extension tube (not shown) is arranged between the powder outlet tube 6 and the scribing tube 4, an adjuster for adjusting an included angle between the outer wall of the powder outlet tube 6 and the outer wall of the scribing tube 4 is arranged between the two, and the adjuster comprises: the powder spraying device comprises an annular outer pipe 11 arranged on the outer wall of the powder spraying pipe 4, an annular inner pipe 12 arranged on the outer wall of the powder spraying pipe 6 and a pressing block 13 radially arranged on the annular inner pipe 12, wherein the annular outer pipe 11 is uniformly provided with a plurality of through holes 14 matched with the outer wall of the pressing block 13 along the axial direction, the annular inner pipe 12 is sleeved in the annular outer pipe 11, one end of the pressing block 13 is fixed on the inner wall of the annular inner pipe 12 through an elastic piece, and the other end of the pressing block 13 penetrates out of; so design, can adjust the distance of two play powder pipe ends through the regulator to can realize the marking off between a plurality of distances, improve the application range of this scriber.
In particular, the regulator is arranged on one side of the powder outlet pipe 6 away from a person; by the design, the powder outlet pipe can be far away from a person, so that lime and the like can be prevented from being scattered on the shoes when the person uses the shoe.
Particularly, one side of the back barrel 1 provided with the braces 3 is provided with an anti-skid massage layer which is made of silica gel; by the design, the back ache caused by long-time work can be prevented, and the comfort of the back of a human body is greatly improved.
The using method comprises the following steps:
at first open the lime that the lid will need to hold or fertilizer and put into back of the body bucket, this moment under the effect of filter screen, bold lime or fertilizer are blockked on the net, little lime powder or fertilizer granule will fall under the net, later bear it in the back through the braces, open the switch, the motor begins to work this moment, the pivot of motor drives helical blade and begins to rotate, and lime or fertilizer will be propelled out the powder pipe along helical blade's rotation, later flow out along a powder pipe tip, until accomplishing the required line of drawing, close the motor, helical blade stops rotatoryly this moment, lime or fertilizer can not get into out the powder pipe along drawing the pipe, thereby can be fast effectual draw required lines.
