Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a device for mixing feed, etc. and transporting it to a predetermined location.

(Prior art and its problems) Conventionally, dairy cows have been fed with a method of feeding concentrate feed and roughage separately.

However, when this method is used, the feed that enters the rumen is digested by the action of microorganisms, but it is difficult to maintain homeostasis in the stomach because the state of fermentation varies depending on the type and nature of the feed. . It may also cause various gastrointestinal diseases such as ruminal phagocytosis and acute flatulence. Therefore, in order to prevent these problems from occurring, safety measures have been taken such as refraining from feeding concentrates or reducing the amount of feed fed. However, in this case, even highly capable cows are unable to fully demonstrate their abilities, and high production cannot be achieved.

It was found that the ad libitum feeding method of mixed feed can reduce these drawbacks and give good results, but it requires extra effort to mix the feed, and this prevents it from being widely used among dairy farmers. This has become a major obstacle.

Therefore, commercially available machines for mixing these feeds include: (1) A cylindrical type with rotating blades on a vertical axis.

(b) A boat-shaped tank in which a horizontal rotating rod stirs the inside.

C. A horizontal screw auger or one with one to three rotating blades.

D. An application of a concrete mixer.

etc. However, these mixers have the following drawbacks. That is, A. Each time a feed is fed, a single feed is weighed, put into a machine, and stirred, but these operations must be repeated several times in a day.

B. In order to make several types of mixed feed with different nutrient concentrations, it is necessary to repeat the process of measuring, mixing, and taking out the feed for each type.

C. When making large quantities at once, a large capacity and high output motor are required.

D Requires considerable strength and robustness.

E: In the event of a breakdown or power outage, a series of operations will come to a halt.

F. Either a conveyor or special equipment for feeding the feed is required either for feeding the feed into the mixer or for removing the mixed feed.

(Means for solving the problem) This idea was researched to solve the above-mentioned drawbacks.In addition to stacking one day's worth of feed in a layered manner in a mixing tank, it also straddles the mixing tank. A stirring mechanism section is installed on the running car body, and the stirring mechanism section can freely enter into the mixing tank, and the stacked feed is scraped up and dropped onto a loading conveyor installed at the rear, thereby thoroughly mixing the feed. It was found that the fed feed can be transported to a designated location and feeding operations can be carried out quickly.

To describe the present invention in detail with reference to the illustrated embodiment, it consists of a mixing tank 1, an unloading machine main body 2 having a stirring mechanism section 7, which will be described later, that can freely enter the mixing tank 1, and a loading conveyor 3. The side wall consists of a door 4 that can be opened and closed freely, and inside, silage, rice straw, beet pulp, compound feed, etc. are layered in layers.
Finally, add layers of vitamins, minerals, salt, and other additives.

The unloading machine main body 2 consists of a traveling vehicle body 6 having an inverted U-shaped straddle portion 5, and a stirring mechanism portion 7 provided on the straddling portion 5 of the traveling vehicle body 6. , 8, it is possible to run freely while straddling the mixing tank 1, and the left and right drive wheels 9, 9... are driven by separate running motors 1.
It is connected to the drive belt 11 of 0, so that driving operations such as turning and going straight can be performed by performing operations such as forward and reverse rotation.

The stirring mechanism section 7 consists of a bucket conveyor 12 and stirring blades 13, and the bucket conveyor 12
is inclined rearward with respect to the traveling direction of the traveling vehicle body 6, and the buckets 14, 14, . . . are structured to scrape off feed in the traveling direction. The stirring blades 13, 13, . . . are fixed to the lower rotating shaft 16 of the lower sprocket 15 of the bucket conveyor 12, and are configured to scrape feed toward the bucket conveyor 12 side. Although the stirring blades 13, 13 are provided with a plurality of semicircular plates tilted, they may also be screw-shaped. The outer circumferential locus of the stirring blade 13 and the bucket 1
4 and 14 so that the lower outer periphery trajectories are approximately the same. In addition, a gap necessary for the side wall of the mixing tank 1 to pass through is provided between the leading edge of the stirring blade 13 or the lower rotating shaft 16 and the leg part 8 of the traveling vehicle body 6, so that the traveling vehicle body 6 can pass through the mixing tank. 1, the stirring mechanism section 7 enters into the mixing tank 1.

The loading conveyor 3 is placed above the bucket conveyor 12 via a communication port 17 that is lowered in the center, and this communication port 17 is provided with a wiper 18 that rotates back and forth. wiper 18
is fixed to a rotating shaft 20 of an arm 19, and the tip of this arm 19 is configured to be rotated up and down by a crank mechanism 22 provided on an upper sprocket 21 of the bucket conveyor 12. Loading conveyor 3
It is best to use one that can be tilted or expanded/contracted. 23 is a cover.

(Function) The present invention is implemented as described above. To use this device, first, one day's worth of various feeds and additives are stacked in layers in the mixing tank 1. For mixing, the opening/closing door 4 of the mixing tank 1 is opened, the traveling vehicle body 6 is made to straddle the mixing tank 1, and at the same time, the stirring mechanism section 7 is made to face the inlet of the mixing tank 1. At the same time as the stirring mechanism section 7 is driven, the traveling vehicle body 6 is gradually advanced according to the processing capacity of the stirring mechanism section 7. The feed is scraped off by the buckets 14, 14 of the bucket conveyor 12, thrown into the communication port 17 at the position of the upper sprocket 21, and dropped onto the loading conveyor 3. A transport vehicle (not shown) is prepared in advance at the drop-off port of the loading conveyor 3, and when the required amount is reached, the next transport vehicle is prepared or the operation of the stirring mechanism section 7 or the traveling vehicle body 6 is stopped. Feed on the sides of the bucket conveyor 12 is stirred by stirring blades 13, 13, brought to the center, and scooped up by buckets 14, 14.

(Effects) As mentioned above, in this case, the feed, etc. stacked in the mixing tank is scraped off by a bucket conveyor by inserting a stirring mechanism installed in the vehicle body that runs across the mixing tank, and scraping the feed etc. The feed located on the sides is stirred by stirring blades and brought to the center and scooped up by a bucket, so the stacked feed is conveyed and fed in a well-mixed state. Also, since the wiper rotates at the connecting port, straw etc. stuck in the connecting port are constantly being forcibly cleaned out, and the mixed feed dropped from the bucket conveyor passes smoothly and is carried to the loading conveyor. .

In the event of a power outage, etc., you can use an all-purpose device.

The proposed device can also be used as a device for mixing and discharging materials other than feed.
