Abstract
The invention discloses a safety switch mechanism of a branch smashingchopping machine comprising a main body part, a hopper and a main power switch, wherein the hopper can be removably dismountablely installed on the main body part; the safety switch mechanism comprises a safety switch and a trigger piece arranged on the hopper, wherein the safety switch has switching-on state and switching-off state and is mutually connected with the main power switch in series; when the hopper is installed to the main body part, the trigger piece triggers the safety switch to cause the safety switch to be in switching-off on state; when the hopper is not installed to the main body part, the trigger piece is mutually separated from the safety switch, so that the safety switch is in switching-off state. Thus, wWhen the hopper is not installed on the main body part, the safety switch can not be triggered, and the main power switch is still in switching-off state all the time, thus ensuring that no personal injury happens because thedue to starting the motor has small possibility of starting by accident occurs, and avoiding potential safety hazard.
Description
Affiliated technical field
The present invention relates to a kind of safety switching mechanism of chipper.
Background technology
Chipper is generally used for the branch in the gardens, branch etc. are shredded so that branch, branch after the chopping are collected and cleared up.This chipper generally comprises main part and is positioned at the hopper of main part below.The top of main part is provided with charging aperture, and portion is equipped with motor, transmission device and cutting tool within it, and wherein cutting tool is installed in the tool rest.In addition, treat that broken branch, branch shred by the inboard that charging aperture enters into main part, the branch that has shredded then, branch drop on the ground by the hopper of main part below.In the prior art, the hopper that has is one-body molded with main part, and the hopper that also has is to separate moulding with main part, by securing members such as bolts hopper is fixed on the below of main part then.Like this; when hopper when main part disassembles or be not in place; just can touch cutting tool unexpectedly from the below of main part; thereby there is certain potential safety hazard; so; chipper for this hopper can be dismantled from main part need provide a kind of safety switching mechanism, and it can not provide safeguard protection to the user when hopper is in place.
Summary of the invention
The invention provides a kind of safety switching mechanism of chipper, it can not provide safeguard protection to the user when hopper is in place.
The technical solution adopted for the present invention to solve the technical problems is: a kind of safety switching mechanism of chipper, described chipper comprises main part, removably be mounted to hopper and power main switch on the described main part, it is characterized in that: described safety switching mechanism comprises safety switch and is arranged on triggering part on the described hopper, described safety switch has closure state and off-state and is connected in series mutually with described power main switch, when described hopper was mounted to described main part, described triggering part triggers described safety switch made described safety switch be in closure state; When described hopper was not mounted to described main part, described triggering part and described safety switch were separated from each other and make described safety switch be in the state of disconnection.
The invention has the beneficial effects as follows, by being provided with the safety switch that is in series with power main switch, and on hopper, be provided with the triggering part that can trigger safety switch, when hopper was mounted to described main part, described triggering part triggered described safety switch, when hopper is not mounted to described main part, described safety switch can not be triggered, make power main switch be in the state of disconnection all the time, having guaranteed not can unexpected starter motor and bring personal injury to the user, has stopped potential safety hazard.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the assembling stereogram corresponding to the chipper of most preferred embodiment of the present invention, and wherein the safety switching mechanism of chipper is broken away.
Fig. 2 is the three-dimensional exploded view of Fig. 1, and wherein the main part of chipper is by biopsy cavity marker devices.
Fig. 3 is the three-dimensional exploded view corresponding to the switch enclosure of the chipper of Fig. 2.
Fig. 4 is the three-dimensional view that the switch enclosure of Fig. 3 is assembled to main part.
Fig. 5 is the enlarged drawing along a circle of Fig. 1.
The specific embodiment
See figures.1.and.2, corresponding to most preferred embodiment of the present invention is a kind of chipper, chipper is generally used for the gardens branch, branches etc. shred, it mainly comprises main part 1, be removably mounted on main part 1 the bottom hopper 3 and be arranged on main part 1 and hopper 3 between safety switching mechanism 2.In addition, this chipper also comprises a frame that has a roller (figure does not show) so that pushing away chipper and move ahead on the ground.
With further reference to Fig. 3 to Fig. 5, above-mentioned safety switching mechanism 2 comprises being arranged on the safety switch 20 in the main part 1 and being arranged on triggering part 24 on the described hopper 3, and wherein triggering part 24 can be matched with described safety switch 20.
Above-mentioned safety switch 20 is a microswitch, and it is connected in series mutually with the power main switch 16 of described chipper.This safety switch 20 has the two states of disconnection and closure and is arranged in the switch enclosure 28.Described switch enclosure 28 roughly is made of double structure, and its inboard is respectively arranged with outward extending a pair of latch 30 with in the corresponding jack 32 that inserts safety switch 20, thereby safety switch 20 is fixed in the switch enclosure 28.In the inside edge of switch enclosure 28, also be provided with a pair of outstanding bolt hole 36, be meshed with above-mentioned pair of bolts hole 26 thereby pair of bolts 38 can penetrate in a pair of through hole 282 of switch enclosure 28 switch enclosure 28 assemblings of double structure are finished.In addition, also be outward extended with hollow posts 40 in the side of switch enclosure 28, the contact 21 of above-mentioned safety switch 20 can be contained in this hollow posts 40, and this hollow posts 40 itself is housed in the through hole 17 that is arranged on the lower cover 13 (Fig. 2).In addition, on the outer surface of switch enclosure 28, be outward extended with convex 44, and on convex 44, offer through hole 46, thereby then screw 48 is passed through hole 46 and be connected on the lower cover 13 that switch enclosure 28 after will assembling on the lower cover 13 is fixed to main part 1 (Fig. 4).
With reference to Fig. 2 and Fig. 5, above-mentioned triggering part 31 is for being fixedly installed on a push rod 31 on the described hopper 3, and corresponding to most preferred embodiment of the present invention, this push rod 31 is one-body molded with hopper 3, and extends upward from the end face 33 of hopper 3.When hopper 3 is mounted to the lower cover 13 of described main part 1 rightly, this first push rod 31 stretches into the hollow posts 40 of the through hole 17 that is positioned at lower cover 13 and the contact 21 of depressing above-mentioned safety switch 20, make it be in closed state thereby trigger safety switch 20, make the power main switch 16 that is in series with safety switch 20 just might be in the state of connection and starter motor; And when hopper 3 is not installed, because of there not being the triggering of push rod 31, make safety switch 20 be in the state of disconnection always, thereby the power main switch that is in series with it 16 is in the state of disconnection always, therefore, avoided accidental switch power main switch 16 when hopper 3 is not installed and starter motor, made cutting tool rotate at a high speed and bring personal injury to the user.Simultaneously, safety switching mechanism of the present invention relatively simple for structure, cost is cheaper.
