Description

[Detailed description of the invention] The present invention uses the vibrating action of the beam rod to vibrate the tube metal.The vibration of the beam rod is additionally transmitted to the tube metal through appropriate means, and This invention relates to making the tube metal vibrate independently of the vibrating lifting blade body.

An embodiment of the present invention will be described based on the drawings.

It is connected with 7.

14 is a bracket fixed to the rear end of the holder 27;
A support piece 21 is rotatably pivoted by a pin 15.

Reference numeral 22 denotes a crank rod in the shape of an angle, which is pivotally attached to the rear end of the fuselage 1 through a shaft 17, and a support piece 21 is pivotally attached to the tip of the arm 11, which has a short swing radius, via a pin 16. The upper end of an extendable and retractable connecting rod 23 is pivotally connected to the rear end of the arm 12 which has a long swing radius through a pin 18.

Reference numeral 24 denotes a tube metal, on which a wide comb-shaped or net-shaped sieve whose rear part is bent at an appropriate angle is fixed to a support plate 26 connected to the rear of the lifting blade body 13 via a hinge 20. , hinge 2
Swings with 0 as the fulcrum.

Reference numeral 25 denotes a gauge wheel placed in front of the beam rod 12 to adjust the excavation depth.

Next, the effect will be explained.

The power input from the tractor T through the shafts p, t, o, and the shaft 9 is transmitted to the mission case 8, and then
is rotated to give the transmission plate 11 vertical swing.

Then, the transmission plate 11 swings the front end of the swinging arm length up and down to swing the swinging arm length about the base shaft 7, and the holder 2
Give 7 a back and forth swing.

In response to this, the beam rod 12 swings back and forth, and the digging L blade body 13 provided at its lower part vibrates back and forth.

At the same time, the cylinder metal 24 also vibrates back and forth because it follows the extracting blade body 13 via the hinge 20, but the support piece 24 also vibrates back and forth.
, by the transmission means of the crank rod 22 and the connecting rod 23,
The back and forth swing of the swing arm length is converted into vertical swing, and the tube metal 24
also vibrates vertically with the hinge 20 as the fulcrum.

This will be explained based on FIG. When the extraction blade body 13 vibrates back and forth from the solid line position to the two-dot chain line position due to the swinging of the swinging arm length, the hinge 20 forms a circle with the base shaft 7 as the center and the radius of the length between the base shaft 7 and the hinge 20. On the orbit, the pin 15 swings on a circular orbit whose radius is the length between the base shaft 7 and the pin 15 by the set angle of the extracting blade body 13, respectively.

As the pin 15 swings, the pin 16 swings through the support piece 21 in a circular orbit with a radius 11 centered on the shaft 17. It oscillates in a circular orbit with a radius of 12.

Here, the swing angle of the pin 18 is the same as the swing angle of the pin 16, but since 71<72, the swing distance of the pin 18 is amplified.

As a result, the connecting rod 23 that pivotally connects the pin 18 swings up and down significantly, moving the fitting tube 19 on a circular orbit centered on the hinge 20 and having a radius equal to the length between the hinge 20 and the fitting tube 19. Vibrate under -L.

In this way, the fitting 24 is given =L vertical vibration that is further independent of the longitudinal vibration of the blade body 13.

The inclination of the cylindrical metal 24 is set by expanding and contracting the connecting rod 23.

If the connecting rod 23 is made shorter, the cylindrical metal 24 will slope steeply, and if the connecting rod 23 is made longer, the slope will become gentler.

The amplitude of the tube metal 24 is the same as that of the fitting tube 19.19 of the connecting rod 23.
Can be changed depending on the fitting position with '.

A fitting pipe 19 in which a connecting rod 23 is provided in front of a barrel metal 24
When it is fitted into the fitting tube 19' provided at the rear of the cylindrical metal 24, the amplitude becomes small.

With the configuration as described above, the following effects have been achieved.

■ Smoothly and amplify the ifJ movement of the holder of the swinging arm through an appropriate transmission means to convert it into vertical swing,
Since we were able to independently vibrate the tube metal up and down, we were able to reliably separate the adhered soil from the excavated material, and the vibration without resistance also damaged the excavated material. lost.

■ Since the connecting rod is made telescopic, the slope of the tube metal can be adjusted according to the depth of excavation, making it possible to reliably dig out the excavated material from the soil as shown in Figure 1. became.

■ Since multiple fitting tubes are provided on the tube metal, it is now possible to obtain amplitudes that match the type of excavated material or soil quality.

■ Since the structure of the transmission means is appropriately simplified, it is easy to manufacture and the manufacturing cost is low.

As described above, it would be of great benefit if the present invention could independently vibrate and adjust the tube metal from a single transmission source without interfering with the vibration of the extracting blade and the digging work. .
