Description

[Detailed description of the invention] This invention relates to a rotating device for a working machine towed by a tractor.
This invention relates to a rotating device in which a fan-shaped sector is provided on a working machine so that the working machine can rotate (roll) independently of the tractor by turning a manual lever pivoted on the fulcrum of the sector.

To explain this idea using a snow blower as an example, there have been snow blowers that are pulled by a tractor and rotate at an angle to clear snow on a flat surface, but we have developed a tractor-driven snow blower as a device that rotates the snow blower at an angle. There are those that are equipped with an adjustment screw, and those that operate the lifting slot using hydraulic pressure.

However, the former method currently does not work due to the load applied during snow removal, and the latter method is expensive, so it is not widely used.

In view of the foregoing, this proposal includes a fan-shaped sector in the center of the snow blower, and a manual bundle that rotates around the fulcrum of the sector as the central axis is connected to rolling arms set on the snow blower on both sides of the sector to rotate the manual bundle. This is a rotating (rolling) device for a snow blower that rotates the snow blower at an angle.

To explain the embodiment of the present invention by taking a snow blower as an example shown in the drawings, Fig. 2 is a perspective view of the working machine 1 (snow blower) when viewed from the back side, that is, the side connected to the tractor 2; This is a scraping screw that rotates around a rotating shaft 4, and the snow scraped by the scraping screw is sent from the screw case 5 to the blower case 6, and the snow sent into the blower case 6 is sent to the blower case 6. The rotation of the internal blower allows the water to be discharged from the ju-turf to the outside.

Reference numeral 8 is a sector having a fan-like planar shape, and an adjustment hole is made in the center of the arc-shaped edge, and a required number of adjustment holes 9 are drilled at the required intervals on both sides, and the sector is mounted so as to protrude from the main part of the sector. The plate 10 is fixed to the center point of the blower case 6 of the working machine 1.

Reference numeral 11 denotes a manual bundle having a T-shaped planar shape, which is rotatably pivoted to the sector by a shaft 13 with the intersection point 12 of the T-shaped overlapped with the center point of the main part of the sector 8. A dowel pin 14 is installed at a position that coincides with the adjustment hole 9 of the sector, and when the manual bundle 11 is rotated, the dowel pin 14 is fitted into one of each adjustment hole 9 of the sector.

Reference numerals 15 and 15' designate mounting plates for rolling arms whose tips are formed into two-pronged bearings 16 and 16' and are fixed symmetrically on both sides of the blower case 6. Reference numerals 17 and 17' designate a pair of left and right rolling arms; The arm is narrow at the upper part and gradually becomes wider as it reaches the lower part, and one side of the lower part is fitted into two pronged bearings 16, 16', and is rotatably pivoted by a shaft 18, 18', and the other side has a pin protruding outside. 19 and 19' are provided, and the upper part is bent into an L shape facing inward to form a bent part 17.

20 and 20' are connection lofts that rotatably connect the bent parts 17□, 17□ of the rolling arms 17, 17' and the T-shaped manual handle 11, and the fan-shaped sector 8, the manual handle 11, and the connection lot 20. The rolling arm 17 and the mounting plate 15 form a rotating device.

21 is a connecting plate in which a shaft hole 22 is formed. When connecting the working machine 1 equipped with a rotating device to the tractor 2, the shaft hole B of the upper connecting rod A of the tractor and the shaft hole 22 of the connecting plate 21 of the working machine are overlapped and the shaft is fixed for free movement. The shaft holes of the lower connecting rods c and c'.

The pins 19 and 19' protruding from the rolling arms 17 and 17' of the working machine are passed through D', and the power of the tractor is transmitted to the working machine through the transmission shaft E, and the tractor 2 is moved in reverse and the working machine is raked. The screw 3 and the blower in the blower case are rotated to remove snow from the juturf.

As described above, the center of the main part of the sector of the rotating device is set at the center of the work machine 1, and the work machine is rotated (rolling) by turning the manual handle 11, so that the fulcrum of rotation is the work machine Because it is located in the center of the body, it requires almost no force to operate and can be rotated easily.

When the dowel pin of the handle is fitted into the adjustment hole at the center of the sector, the work machine is held horizontally, and when the manual nozzle 11 is turned in the direction of arrow A, the rolling arm 17' is moved to the shaft 18' through the connecting rod 20'. The working machine tilts to the arrow A side, and when the manual handle 11 is turned to the arrow side, the rolling arm 17 ascends through the connecting rod 20 using the shaft 18 as a fulcrum, and the other rolling arm 17 descends. The slope of the snow blower can be increased or decreased by tilting the descending working machine toward the arrowhead side and turning the manual handle to move the dowel pin 14 to the adjustment hole 9 outside the sector.

Therefore, if there is a high snowdrift on one side of the snow removal road, the snow can be removed evenly from the road surface by tilting the working machine toward the side where the snowdrift is.

As described above, the rotating device of the present invention has a simple structure, can be manufactured at low cost, and parts can be easily replaced in the event of a failure, and can be used in snow blowers and agricultural working machines.
