Description

[Detailed description of the invention] The present invention relates to a stirring device for stirring and mixing two or more types of powder materials necessary for all mixing operations, and its purpose is to arbitrarily set the inclination angle of the stirring drum that accommodates the contents. It has been made possible to increase the total capacity of contents by making it adjustable, thereby increasing the efficiency of stirring and mixing operations.

Conventionally, for example, when two or more types of powder materials were to be completely stirred, the contents were poured into a built-in drum that could be rotated four times by a rotary screw, and the screw was rotated to mix the contents.

However, this method has disadvantages in that the contents to be stirred accumulate in the gap between the screw and the drum, making the stirring operation insufficient, and that the contents cannot be removed quickly and easily because they are obstructed by the screw.

In order to completely improve this, a device has recently been proposed in which the stirring drum rotates four times using a friction wheel and is oscillated at a constant angle by a metal crank mechanism to quickly and reliably stir the contents.

However, in this method, if the inclination angle of the stirring drum that is swung by a crank mechanism is increased, the weight of the contents will be agitated each time the contents move from the front to the rear inside the stirring drum while the stirring drum is oscillating. If the front or rear part of the drum is located at the front or rear part of the drum, there is a risk that the stirring drum will fall from the friction wheel, so the stirring drum cannot be swung with a loud tilt angle.
It had to be made smaller.

However, if the oscillation of the stirring drum is made smaller, the stirring drum cannot turn its inlet all the way up when collecting the contents, so it is not possible to accommodate the amount suitable for stirring and mixing all the contents, and the work is difficult. It was inefficient.

The problem can be solved by removing the stirring drum from the friction wheel and loading and unloading the contents, but the work requires considerable effort and effort4.
There were some drawbacks.

The present invention eliminates all of the above-mentioned drawbacks, and when the stirring device is in operation, the stirring drum is swung at a small angle of inclination of 4, and only when the contents are to be accommodated, the stirring drum is tilted further than when it is in full operation. This is designed to increase the storage capacity, and will be explained below with reference to all the drawings of the embodiment of the present invention. 1 is a plywood frame framed in an angular rectangular shape, and a support shaft 2 is fully protruded from the center of both sides of the plywood, and the above-mentioned stand is The base plate 1 is rotatably attached to the support column 4 by being inserted into a bearing 5 provided at the upper end of the support column 4 which stands upright on a base 3 which is framed in a rectangular shape like the plate 1.

The electric motor 12 rotates the friction wheel provided on the pivot shaft I by 8°9.

Reference numeral 16 denotes a drive device 20 consisting of an electric motor 17 and a speed reducer 19 drivingly connected to the electric motor 17 via a belt 184.
As shown in FIG. 3, this mount 16 has support shafts 21 and 21' protruding from both ends in the longitudinal direction.
It is mounted on the base 3 so as to be rotatable back and forth by being inserted into bearings 22, 22' provided at the ends of the base 3.

Reference numeral 23 denotes a crank mechanism provided between the rear end of the base plate 1 and the drive device 20, which includes a crank 24 fixed to the drive shaft of the reducer 19, and a crank 24 pivoted to the lower end of the crank 24, with the base plate 1 at the tip. The crank mechanism 23 drives the base plate 1 to rotate the seesaw back and forth at an angle of approximately 200° with the support shaft 2 as the center. It sways like that.

Reference numeral 27 is an operating rod, which has a bearing 22 that fully supports one side of the mounting base 16.
It is fixed on the outside of the base 3 to a rotation shaft 29 inserted through a shaft support plate 28 provided on the base at a position on the same line as ``, and is fixed toward the upper part of the handle metal on the outside of the base 3, and on the opposite side of the rotation shaft 29. The lever 30 is fixedly swayed completely downward at the tip.

Reference numeral 31 designates a connecting rod which is pivotally connected to a lever 30 at one end, and whose tip tf is pivotally connected to a drive rod 32 fixed to one support shaft 21' of the mount 16, and which is arranged horizontally at the bottom of the base 3. .

Reference numeral 33 denotes a mounting plate that supports the rear lower end of the mount 16, and supports the mount 16 horizontally on the base 3 together with the entire support shaft 21, 21'.

Reference numeral 34 denotes a locking plate having a cutout hole 35 at the tip, which protrudes from the center of the rear of the mounting base 16 to the rear of the base 3. A fixing fitting 39 consisting of a bolt 37 rotatably mounted on the bolt 37 and a tightening handle 38 that is engaged with the entire notched hole 35 of the bolt 37 and screwed onto the protruding end thereof is used to separate the bolt 37 from the base 3. It is freely fixed and completely prevents the mount 16 from swinging during operation of the drive device 20.

A stopper 40 extends from the rear of the drive rod 32 and protrudes from the base 3. When the mount 16 is tilted forward, the stopper 40 receives the drive rod 32 metal and controls the entire inclination angle of the mount 16.

41 are casters with brakes attached to the four corners of the base 3,
Reference numeral 42 designates a hollow cylindrical stirring drum, the front part of which has an open surface 43 gold, and the rear part closed to form a hollow truncated cone shape, and the outer periphery is provided with 444 protrusions at both ends. By fitting the friction wheels 8, 9 of each set into the space formed by the 62 friction wheels forming a set, the stirring drum 42 has a protrusion 44 on the friction wheels 8°9. It is rotatably mounted on the vehicle while being locked to the vehicle.

45 is an opening surface 4 at the top, bottom, left and right positions of the inner surface of the stirring drum 42.
A scraping plate 46 is provided from 3 to the rear, and is a lid detachably attached to the opening surface 43 of the stirring drum 42.

Next, to explain the operation, when putting the contents 4 to be stirred into the stirring drum 42, after removing the lid 46, the opening surface 43 of the stirring drum 42 is turned diagonally upward by the crank mechanism 23 as shown in FIG. Tilt it so that it looks like this.

In this state, unscrew the fixing metal 39, tighten its bolt 37, move it back together with the handle 38, pull it away from the notch hole 35 of the fixing plate 34, and pull the operating rod 27 to the left in Figure 1 to rotate. A lever 30 connected to the operating rod 27 by a shaft 29
Push the connecting rod 31 to the opposite side of the operating rod 2T and connect the connecting rod 31.
The drive rod 32 which is pivotally connected to the mounting base 1 rotates counterclockwise.
64 Rotate the support shaft 21, 21' on the front side of the base 3 until the drive rod 32 comes into contact with the straight rod 20 (-40), tilt the drive device 20 completely, and connect the crank mechanism 23 with the drive device 20. Pivot point 4 can be moved diagonally downward.

As a result, the crank mechanism 23 causes the base plate to be tilted (30° in this embodiment) from the entire center of the support shaft 2 to the stirring drum 42, as shown in FIG.

Then, the entire contents are introduced into the stirring drum 42 through the opening surface 43.

At this time, the capacity of the contents depends on the inclination angle of the stirring drum 42?
The larger the capacity, as shown by the two-dot chain horizontal line S in FIG.

However, when the inclination angle of the stirring drum 42 is only as shown in FIG. It cannot be accommodated.

After loading the contents, cover the opening surface 43 with the lid 464 and press the operating rod 2.
7. As shown in Figure 1, return to the original position and attach the mounting base 16.
After making it horizontal, fix it to the mounting table 164 and the base 3 using the fixing fittings 39.

After this, electric motor 12.17! When rotated, the stirring drum 42 is rotated by the friction wheels 8 and 9, and at the same time, the crank mechanism 23 converts the electric motor 170 revolutions into a reciprocating motion up and down, causing the stirring drum 42 to rotate within the range shown in FIG. Shake the top plate 4 to get the contents by swinging it back and forth like a seesaw at the angle.
5 to stir the stirring drum 42 while shaking it along the inner peripheral surface, and move the contents from the opening surface 43 of the stirring drum 42 to the bottom side, and conversely from the bottom surface to the opening surface 43, and stir. Capacity 4 has been further improved and all contents are stirred and mixed.

When all the contents are to be taken out, the stirring drum 42 is tilted forward by the crank mechanism 23 so that the opening surface 43 is diagonally downward, the cover body 46 is removed, and the contents are discharged from the sound opening surface 43.

In addition, instead of connecting the operating rod 27 to the connecting rod 31 through the lever 30, a portion corresponding to the lever 30 is extended, and is pivotally connected to the base 3 inside the base 3, so that it is connected to the connecting rod 31 directly below the pivot point. The connecting rod 31 may be entirely directly attached to the tip of the support shaft 21', and the drive rod 32 may also be vertically mounted on the underside of the mounting base 16 without being fixed to the support shaft 21' so as not to hinder the rotation of the mounting base 16. The present invention is also advantageous when connected to the connecting rod 31.

As mentioned above, the present invention allows the stirring drum to be placed in the slanted container by moving the mounting base mounted on the drive device 4 times and pulling the crank mechanism 4 connected to the drive device diagonally downward when loading the contents. In order to completely suppress the capacity of the contents, when stirring the contents, the above-mentioned mounting base is returned to the horizontal state, and the stirring drum is rotated by the friction wheel at the same time as the stirring drum is rotated by the friction wheel. The mechanism is designed to stir and mix the contents efficiently by swinging it back and forth at a safe inclination angle like a see-no, and unlike conventional methods, the inclination angle of the stirring drum makes the noise louder in order to fully incorporate the contents. In order to mix the metal with the stirring drum, increasing the inclination angle makes the operation of the stirring drum dangerous, or by reducing the inclination angle 4, the total capacity can be suppressed and work efficiency decreases. This is completely different from the above, but in this case, the inclination angle of the stirring drum is increased only when loading the contents compared to during full operation to increase the storage capacity, and during operation, the inclination is set at 4 small angles to allow safe operation of the stirring drum. In addition, since only the amount of contents that can be agitated by sound can be accommodated, the stirring and mixing work can be carried out efficiently.

When adding contents, the entire stirring drum can be tilted easily and at a large angle via the crank mechanism 4 by simply tilting the mounting base of the driving device forward using the operation lever. The device has a simple structure, which is simply tilted forward by a mounting base rotatably attached to a base using an operating rod and a connecting rod connected to it, so that it can be easily operated. Moreover, it can be manufactured economically, and since the mounting base is firmly fixed to the base using the fixing bracket while the stirring device is in operation, the operation of the stirring drum can be performed smoothly without any disturbance. It has many remarkable effects, such as being able to do so.
