Description

[Detailed description of the invention] The present invention relates to a mixing device for powder and granular materials, and in particular, a device that mixes and feeds several types of feed when feeding feed to many parallel feeding surfaces in a cattle shed. It is related to.

In this type of conventional technology, a boat-shaped mixing tank is mounted on a self-propelled vehicle driven by electric power, and a screw conveyor is built in the bottom of the mixing tank in the front and back direction, or a screw conveyor is built in the bottom of the mixing tank and the top of the tank A scraper conveyor (having a large number of scraping plate blades arranged horizontally on an endless band) is installed between the scraper conveyor and the inclined chute, and feed is fed from the inclined chute while being scraped up with this conveyor. It was a device that continuously fed the chute while moving the chute forward one after another within the mixing tank.

By the way, in the case of feeding a cattle shed, for example, a large number of raw materials such as wheat bran, starch lees, beer lees, and the following are fed separately in layers in order to uniformly mix them in a mixing tank.

For this reason, in the devices using the conventional screw conveyor described above, there is almost no mixing and the material is discharged, and even in the device using a scraper conveyor, when the scraper with the scraping plate blade scrapes up the raw material in the bottom layer, the material is scraped up. The upper raw material layer is scraped up only by the next scraper, and even if each raw material is stored in layers, it is supplied from the inclined chute to the feeding surface without being sufficiently mixed.

Therefore, a separate stirrer for mixing is required, and a transmission device, motor, etc. are required to drive the stirrer.
They were larger, had more complicated structures, and were more expensive.

Therefore, the present invention was devised to solve this problem, and to explain it with reference to examples, Fig. 1 is an overall schematic diagram, Fig. 2 is a sectional view taken along A-A in Fig. 1, and Fig. 3 is a front view of the cutting and scraping device, FIG. 4 is a sectional view taken along the line B-B in FIG. 3, and FIG. 5 is a perspective view of the main parts. A self-propelled vehicle G with two wheels whose front wheels 2 are driven by a motor (not shown), a semi-cylindrical mixing tank 3 as shown in FIG. It is generally composed of a cutting and scraping device C as shown in FIGS. 3, 4, and 5, and a canopy 20 that covers the cutting and scraping device C.

First, to explain the mixing tank 3, as shown in FIG. 1 and FIG. A sliding door 2 to which 5 is attached and slides between the rails 4 and 5 to open and close the side wall.
There are 6.

Further, a flange 8 of an inclined chute 7 that slides between the upper and lower rails 4 and 5 is held between the upper and lower rails 4 and 5.

Next, the new Kiri-1 raking device C will be described. As shown in FIG. 3, there is one drive screw 11 and two slide shafts 12.
12' is the rotating plate 18. It is being erected at 18'.

Specifically, the rotating plates 18 and 18' are rotatably supported by the front and rear mirror plates 9 and 10 of the mixing tank 3, and
The drive screw 11 is screwed into the slide nut 13, and the slide shirt 1-12. 12' is loosely fitted into the slide nut 13, and the drive screw 11 is loosely fitted at both ends at the center of the rotary plate 18 and 18'.
Moreover, it is supported and fixed to the mirror plate 9.10 of the mixing tank 3 by a bracket (not shown) so as not to rotate or revolve.

The slide shaft 12.12' is deviated from the center of rotation of the rotary plate 18. fixed at 18';
It is adapted to revolve by the rotation of the rotating plates 18 and 18'.

Therefore, the rotating plate 18 is rotationally driven by the pulley 25, and as a result, the slide shirt h12. 12' revolves and rotates the slide nut 13.

On the other hand, since the drive screw 11 is stationary, the slide nut 13 moves forward and backward while rotating along the pitch of the drive screw 11.

Therefore, the boss 1 of the disk blade body 14 is attached to this slide nut 13.
Since the blades 5 are fitted and fixed, the disc blade body 14 moves forward at the same time as it rotates.

As shown in FIGS. 3 and 4, the disc blade 14 has
Two arc-shaped cuts 16 are made eccentrically and radially, and one of the cuts 16 is bent outward (in the direction of movement in the direction of arrow C in FIG. 5) to protrude into a cutting blade 17. As shown in FIG. 5, a donut-shaped ring 19 is connected to the back of the disc blade 14 in the direction of movement by a number of angle members 21 and is fixed in parallel with the disc blade 14.

This angle member 21 has a function as a scraper so as to release the bait cut and scraped by the cutting blade 17 in the centrifugal direction.

Next, to explain the canopy 20 that covers the cutting 1 new scraping device C, as shown in FIG. The bait released in the centrifugal direction is guided and led to the inclined chute 7.

The canopy 20 is connected to a rail 22 provided on the upper edge of the mixing tank 3.
22, and is integrated with the inclined chute 7 by a connecting body 27.

Note that 23 indicates an operating handle.

The operation of the feeding device of the present invention that has been stolen as described above is as follows.

Pulley 25 rotated by motor 24 (see Figure 5)
When the rotation plate 18 is driven to rotate, the drive screw 11 is screwed together and the slide shaft 12. The slide nut 13 into which the slide nut 12' is loosely fitted rotates as shown in FIGS.
Since the slide nut 1 moves in the direction of the arrow in FIG.
The disc blade 14 fixed to 3 moves forward while rotating, and cuts each layer uniformly with the arc-shaped cutting blade 17 of the various bait materials stored in layers in advance in the mixing tank 3, and bends them. On one side of the 29 cut, the raw material is forced into the back of the disc blade 14 uniformly in each layer.

The scraped various raw materials are used as angle materials 2 for multiple scrapers.
1 is centrifuged while being further mixed, thrown into the opening of the inclined chute 7 along the inner surface of the canopy 2o, and supplied to a feeding box (not shown) from the inclined shoe 1-7.

Here, the canopy 20 and the inclined shoe 1-7 are integrally connected by a connecting body 27, and are intercepted so as to advance by the rotation of the threaded rod 28 as the disc blade 14 advances. Tank 3
The entire amount of bait stored therein is thrown into the inclined shoe 1-7 while being mixed and stirred, and since the entire device moves, it is sequentially supplied to the required bait boxes arranged in parallel.

Note that the cutting and scraping device C is moved backward by rotating the motor 24 in the reverse direction.

- In short, the present invention involves screwing a slide nut I.13 onto a drive screw 11 horizontally fixed in the internal combustion engine of the mixing tank 3, fixing a blade body to the slide nut I.13, and screwing the drive screw into the drive screw. This is a mixing device for powder and granular materials, in which a slide shaft 12 that can revolve around a shaft 11 is inserted into the slide nut 13, and mixing blades are fixed to the back of the blade body to perform mixing while cutting. be effective.

■ By revolving Slide Shirt I/12,
Since the slide nut 13 is rotated, the blade and mixing blade fixed to the slide nut 13 rotate and mix the powder and granules in the mixing tank 3 while cutting them.

On the other hand, since the slide nut 13 is screwed into the fixed drive screw 11 at its center, the slide nut 13 advances according to the thread pitch of the drive screw 11 as the slide nut 13 rotates.

Therefore, as the process progresses, new powder and granules in the mixing tank 3 are mixed while being cut.

Therefore, since the blade body and the mixing blade are rotated and advanced in one drive, the drive mechanism can be extremely simplified.

- Since the mixing blade moves and rotates at the same time, unlike rotating at the same position, it constantly mixes new powder and granules, and the mixing is complete.

■ If this granular material is used as feed, the feed in the multi-layered mixing tank will be well mixed.
