Description

[Detailed Description of the Invention] The present invention relates to a sight rake for collecting grass, straw, etc. that is used as a baler or the like to pick up, compress, and pack scattered grass, straw, etc. while moving on its own.

In conventional sight rakes, one rotating shaft protrudes far beyond the width of the vehicle body in order to collect grass and other grass over a wide area.

For this reason, the sight rake must be removed every time the vehicle is driven during non-working hours, on narrow roads, or when mounted on a truck or the like, which is very troublesome.

Therefore, in this invention, the sight rake is made to be foldable, and when working to collect grass, etc., the sight rake is extended to collect grass, etc. in a wide range, and when the sight rake is not running, etc., it can be folded and stored to prevent obstructions. The purpose is to provide a site rake that does not become.

The present invention will be described below with reference to the drawings.

The baler soil with the site rake according to the present invention is the power part 2
, a running section 3, a grass collecting section 4, a picking section 5, and a compression packing section 6.

The power section 2 consists of an engine 10 located at the rear of the aircraft, and its power is transmitted to each section 3, 4, 5, 6 through a power transmission device.
to communicate.

The traveling section 3 includes a front wheel 11 and a rear wheel 12, and a steering operation device 13 causes the baler 1 to move forward, backward, or turn.

The grass collecting section 4 is a folding sight rake 14 according to the present invention.
Grass, straw, etc., are collected in front of the dumping section 5.

The disposal section 5 picks up and sends the grass collected by the pick-up claw 7 to the compression packing section 6.

The compression packing unit 6 is comprised of a feeding device, a binding device, etc., and compresses the fed grass, packs it into a predetermined size, and throws out the packed grass bundle from a bale chute 9 located at the rear of the machine.

The folding sight rake 14 has a horizontal frame 16 that is vertically slidably supported by a frame 15 located at the front of the machine body.

A hydraulic cylinder 8 for vertically adjusting the sight rake 14 is connected to the horizontal frame 16 approximately in the center thereof, and an input shaft 17 is rotatably attached to one end thereof, and an intermediate shaft 18 is fixed to the other end. I support it.

The input shaft 17 is connected to a power transmission device via a universal joint 19, and a pulley 20 is fixed to the end thereof.

A boss portion 21' of a pulley 21 is rotatably supported on the intermediate shaft 18, and a spring stopper 22 is fixed to the end thereof.

A V-belt 24 having tines 23 attached at equal pitches around the entire circumference is wound around the pulleys 20 and 21.

A rotating frame 25 and a pulley 26 are rotatably supported on the boss portion 21' of the pulley 21.
5 has a support shaft 28 that rotatably supports the pulley 27 at one end thereof, and a pin hole 31 that can engage with a locking pin 30 of a bracket 29 protruding from the horizontal frame 16 at approximately the center and the other end thereof. .32 is provided.

As described above, the pulley 26 and the boo 1127 are provided with tine 3.
3 is a V-belt 3 attached at equal pitches around its entire circumference.
4 is wrapped around it.

A spline 35 is formed at the end of the boss portion 21' of the pulley 21, and a dog clutch 37, which has a spline 36 formed on the inner circumference so as to mesh with the spline 35, is inserted into the boss portion 21'. has been done.

The dog clutch 37 has one engaging pawl 38 with a taper A on one side on one side, and the other side is pressed by a spring 39 held between the spring stopper 22 and engaged. It can be engaged with an engagement groove 40 having a similar taper A formed on the pulley 26 with the mating claw 38.

Next, the effects of the present invention will be explained.

As shown in FIGS. 2 and 4, the locking pin 30 of the bracket 29 is inserted into the pin hole 31 of the rotating frame 25 by extending it.
By inserting the sight rake 14, the sight rake 14 becomes in an expanded state where it can collect grass and the like over a wide range.

In this state, the power unit 2 connects the input shaft 1 via the universal joint 19.
7, the V-belt 24 having tines 23 is rotated by the pulley 20, and then the pulley 21. The pulley 26 is rotated via the boss portion 21', the spline 35, and the dog clutch 37, and the pulley 28 is similarly rotated.
A V-belt 34 having tines 33 stretched between the two is also rotated.

On the other hand, by adjusting the sight rake U to an appropriate height using the hydraulic cylinder 8 and moving the baler 1 using the traveling section 3, the sight rake 14 can collect grass, etc. over a width wider than the width of the front wheels.

Next, as shown in FIG. 3, when folding and storing the rake, pull the dog clutch 37 against the spring 39 to disengage the spline 35 of the boss portion 21', and is rotated clockwise so that the engaging claw 38 and the engaging groove 40 are not engaged with each other, and the spring 39 is brought into contact with the side surface of the pulley 26 (see FIG. 5A).

Next, the locking pin 30 is removed from the bottle hole 31, and the rotating frame 25, which can now rotate freely, is rotated 180 degrees around the boss portion 21' of the pulley 21, and the locking pin 30 is inserted into the bottle hole 32. By inserting and attaching the rotating frame 25 to the bracket 29 again (see FIG. 5).

As a result, the sight rake 14 is housed within the front wheel width of the baler 1, so that by lifting the sight rake 14 with the hydraulic cylinder 8, the bale 21 can run without being obstructed by the sight rake 14.

Even when the sight rake 14 is stored, when the input shaft 17 is rotated to rotate the boss portion 21' of the pulley 21, the dog clutch 37 engaged with the spline also rotates, and after approximately half a rotation, the engaging pawl 38 and the engagement groove 40 engages,
The sight rake 14 can be activated.

From this state, when the locking pin 30 is removed from the pin hole 32 and the rotating frame 25 is extended again, the dog clutch 37 is It can be automatically disengaged and the sight rake 14 can be placed in an extended state.

Similarly, in this state, by rotating the input shaft 17, the engaging claw 38 and the engaging groove 40 are engaged with each other, and the sight rake 14 is activated. We have described the sight rake 14 that can be folded in two around the intermediate shaft 18 using two pairs of bells 25 and 34, which constitute the body. The winding, which is wound around a rotating body (pulley) whose both ends are supported by an intermediate shaft, may be folded into three or four pieces with the body interposed, so that a wider range of grass can be collected. Of course.

Since the present invention has the above-described configuration, it is possible to collect grass and straw over a width considerably wider than the width of the vehicle body, and the work can be carried out efficiently by reducing the number of turns.

Furthermore, when not in use, the hoist can be easily stored within the vehicle body width by simply folding the body 34 around the intermediate shaft 18, eliminating the need to remove the entire sight rake or the joint shaft each time. , and even when the bodies of the windings are folded, the bodies of the windings are lined up next to each other and do not protrude significantly forward, so that the sight rake 14 can be easily raised. It is easy to drive on narrow roads, store in narrow places, and load onto racks, etc., and if you do not necessarily need to collect grass in a wide area, you can fold the rake according to the situation, and it is easy to turn. You can collect grass.
