Abstract

PROBLEM TO BE SOLVED: To secure reliability of an auger clutch, a traveling clutch and an operating mechanism for the clutches and simultaneously reduce a worker's labor. SOLUTION: In this snow plow 10, operating left and right handles 17L, 17R are extended backward from the machine body, a grip 18 is stretched between the rear ends of the handles, the traveling clutch 60 is operated by a traveling operating member 90, and the auger clutch 70 is operated by an auger operating member 77. The traveling and auger clutches are belt tension mechanisms. The auger clutch rotates a roller driving motor 74 in the normal direction to press a tension roller 72 to a belt 37, and the roller driving motor is rotated in the reverse direction to return the tension roller. A traveling operating member is resiliently sprung toward the release side. A traveling wire cable 65 for operating the traveling clutch is connected to the traveling operating member. The roller driving motor is operated by electric linkage of a limit switch 100 operated with the traveling operating member with a switch forming the auger operating member.

And the roller 53 returns to the position indicated by the solid line, and the belt 53 is
By setting it to the loose state, the driving clutch 60 is turned off.
Become. Thus, the traveling operation member 90 can be used to
Operating the travel clutch 60 via the table 65
Can do. Incidentally, the traveling operation member 90 is attached to the handle 1.
A clutch 60 for running by swinging to the 7L and 17R sides
Is turned on together with the travel operation member 90.
A tongue piece member (to be described later) for the limit switch 10
0 is detected and detection signal, that is, clutch on signal for driving
Issue a number. Next, the auger clutch 70 will be described.
The The auger clutch 70 is connected to the drive pulley 36 and the driven pulley.
Acting on the belt 37 wound around the roller 38
The tension roller 72 is pressed and the belt 37 is
Power is transmitted by tension, and the tension roller 72 is returned.
The belt 37 can be loosened so that power is not transmitted.
It consists of a belt tension mechanism that can be used. The auger clutch 70 is driven by a roller.
Such as wire cables and ropes
Pulling the flexible wire 82 allows the tension roller 72 to be
The roller 7 and the roller drive motor 7.
4 to reverse and loosen the flexible wire 82 to return
The tension roller 72 is returned by the return action of the member 73.
It is characterized by the above structure. More specifically, the auger clutch
70 is a tension low attached to the clutch arm 71.
And a return member for returning the tension roller 72
Return spring 73 and roller driving motor 74
Tens against the return action of the return spring 73 as a drive source
Tensioner that presses the tension roller 72 against the belt 37
The member 75 and the limit switch 100 are turned off or auger
Based on information that clutch switch 77 is turned off
The tension roller 72 is rotated reversely
To drive the roller so that the belt 37 is loosened
And a control unit 78 for controlling 74. The tensioner member 75 is a clutch arm.
A tension spring 81 connected to the
The flexible wire 82 connected to the other end and the flexible wire 82 are wound.
Drum 83 to be taken and gear set to rotate drum 83
84, and the roller drive motor 74 rotates forward.
And the drum 83 is rotated forward through the gear set 84 to be flexible.
Pulling the conductive wire 82, the clutch arm 71 indicated by the solid line
Turn clockwise and tighten with the tension roller (imaginary line) 72
Tighten the bolt 37. The forward rotation of the roller driving motor 74 is flexible.
The extension member 85 extended from the wire 82 is connected to the first switch 86.
Continue until detected. On the other hand, the roller driving motor 7
4 is the extension member 85 extended from the flexible wire 82.
Is continued until it is detected by the second switch 87. 1st and 1st
2 switches 86 and 87 are non-contact type reed switches, for example
Consists of. In this way, the auger operating member is switched
(Auger clutch switch 77)
The power of clutch switch 77 and limit switch 100
The motor 74 for driving the roller is operated by gas cooperation.
By doing so, the auger clutch 70 is
It can be operated with a latch switch 77. The action of tensioning the belt 37 is as follows.
The Limit switch 100 and auger clutch switch
When the control unit 78 receives the information that the switch 77 is turned on, the control unit 78
A normal rotation command is issued to the motor rotation direction control unit 79 to rotate the motor.
The direction control unit 79 sets the positive / negative polarity, and the roller drive motor
The machine 74 is rotated forward. Roller drive motor 74 rotates forward
Then, the drum 83 is rotated forward, the flexible wire 82 is drawn,
Turn the clutch arm 61 shown by the solid line counterclockwise in the figure.
Then, tighten the belt 37 with the tension roller 62 (imaginary line).
Make it stretched. The forward rotation of the roller driving motor 74 is a flexible wire.
The extension member 85 extended from the material 82 is moved by the first switch 86.
Continue until detected. The action of loosening the belt 37 is as follows.
The Limit switch 100 and auger clutch switch
The control unit 78 that has received the information that the switch 77 is turned off
A reverse rotation command is issued to the motor rotation direction control unit 79 to rotate the motor.
The direction control unit 79 reverses the positive electrode / negative electrode to drive the roller.
Machine 74 is reversed. The flexible wire 82 becomes loose
Therefore, the pulling action of the return spring 73 becomes effective,
Clutch arm 71 and tension low indicated by imaginary lines
The belt 72 returns to the position of the solid line, and the belt 37 is loosened.
To do. Note that the second arm indicates that the clutch arm 71 has returned.
Detected by the switch 87, and based on this detection signal, the control unit
78 stops the operation (reverse rotation) of the roller drive motor 74.
The With such an auger clutch 70,
For example, the roller driving motor 74 is rotated in the forward direction so that the flexible wire 8
2 pulls the tension roller 72 against the belt 37.
And reverse the roller drive motor 74
Returning the return spring 73 by loosening the flexible wire 82
By this action, the tension roller 72 can be returned. Next, the control unit 78 shown in FIG.

Claims (1)

[Claims] [Claims] [Claim 1] The body is provided with a driving wheel for traveling and an auger, and a traveling clutch incorporated in a power transmission mechanism of the driving wheel is operated by a traveling operation member to transmit the power of the auger. An auger clutch incorporated in the mechanism is operated by an auger operating member, left and right handles for operation are extended rearward from the machine body, and a grip is spanned between the rear ends of these handles. The travel clutch and the auger clutch transmit power by pressing a tension roller against a belt wound around a pair of pulleys, respectively, and transmit power by releasing the tension roller and loosening the belt. In the snowplow constituted by the belt tension mechanism, the belt tension mechanism of the auger clutch rotates the roller driving motor in the normal direction. The tension roller is pressed against the belt by pulling a flexible wire, and the tension roller is returned by a return action of a return member by loosening the flexible wire by reversing the roller driving motor. The travel operation member is a substantially gate-shaped lever in a plan view including left and right arm portions extending along the left and right handles and a lever portion extending along the grip, and both left and right end portions of the portal lever Is attached to the left and right handles so as to be able to swing up and down, a return spring that repels the lever part in a direction away from the grip is attached to the left or right arm part, and the traveling wire cable for operating the traveling clutch is attached to the right or Limit that is connected to the left arm and turned on and off by a tongue member that swings together with the travel operation member A snow remover characterized in that a switch is attached to a handle, the auger operating member is constituted by a switch, and the roller driving motor is operated by electrical cooperation between the switch and the limit switch.
