DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain mixing device for mixing grains in a predetermined weight ratio.

The present invention controls a variable discharge amount discharge valve provided on the discharge side of a grain tank to control the discharge amount of each mixed grain from each grain tank in units of weight, thereby mixing the grains in a weight ratio. The purpose of this invention is to provide a grain mixing device that can perform the following steps.

An embodiment of the present invention will be described below with reference to the drawings.

Next, the operation of the above configuration will be described.

The volumetric weight measuring meter 1 measures the volumetric weight, which is the weight per unit volume, of each type of grain, and the grain is loaded into grain tanks T ₁ to _{T 2} for each type by the conveying device 2 . Further, the volumetric weight of each product type measured by the volumetric weight measuring meter 1 is stored in the storage section of the arithmetic and control device 7 for each product type.

In this way, the grain tanks T ₁ to _{T 5} are filled with grain of each type, and the arithmetic and control unit 7 stores the dimensional weight of the grains stocked in each of the grain tanks T ₁ to _{T 5} . . Next, to mix the grains of each variety, enter the mixing ratio and total weight on the keyboard.
When the input is from 0, the arithmetic and control unit 7 determines the discharge valve B ₁ of each grain tank T ₁ to T ₅ based on the volumetric weight of each variety.
~ Calculate the rotation speed of B ₅ . In other words, the total weight
W ₀ , the mixing weight ratio of grains in each grain tank T ₁ to _{T 5} , for example, grain tank T ₁ :T ₂ :T ₃ :T ₄ :T ₅ =
If 1:2:3:4:5 is specified, the respective discharge weights W ₁ ~ from each grain tank T ₁ ~ T ₅ are
W ₅ is, W ₁ = W ₀ /15, W ₂ = 2W ₀ /15, W ₃ = 3W ₀ /15, W ₄ = 4W ₀ /15, W ₅ = 5W ₀ /15 ... (1) (W ₁ ~ W ₅ is the discharge weight of each grain tank T ₁ ~ T ₅ )
becomes. And variable discharge amount type discharge valve B ₁ ~
Let the discharge capacity per revolution of B ₅ be V, and the dimensional weight of each grain type filled in each grain tank T ₁ to _{T 5} and stored in the storage section of the arithmetic and control unit 7 is respectively
When W ₁ to _{W 5} are given, the rotation speeds n ₁ to _{n 5} of the discharge valves B ₁ to _{B 5} are as follows.

(2)... n ₁ = W ₁ / (V・W ₁ ) = W ₀ / (15・V・W ₁ ) n ₂ = W ₂ / (V・W ₂ )=2W ₀ / (15・V・W ₂ ) n ₃ = W ₃ / (V・W ₃ ) = 3W ₀ / (15・V・W ₃ ) n ₄ = W ₄ / (V・W ₄ )=4W ₀ / (15・V・W ₄ ) n ₅ = W ₅ / (V・W ₅ )=5W ₀ / (15・V・W ₅ ) The arithmetic and control unit 7 performs the calculation shown in the above equation (2), and each discharge valve B ₁ to B ₅ A pulse motor or the like that rotates each discharge valve _{B1 to B5 is} operated to rotate each discharge _valve to the calculated rotation number _n1 to _n5 .

In this way, the discharged grains of different types are sent to the agitator 5 by the conveying devices 3 and 4, where they are stirred and mixed, and then conveyed to the next step by the conveying device 6.

In addition, each data of the grains mixed in this way is displayed and printed by the display device 8 and the printer 9.

Furthermore, although the above process was a batch process, in the case of constant mixing, the number of revolutions of each discharge valve B ₁ to _{B 5} calculated by the above equation (2) should be calculated as the number of revolutions per unit time. And it is sufficient.

As described above, this device automatically mixes grains according to the weight ratio by simply inputting the grain weight mixture ratio and total weight, so it is easy to obtain grains with any weight mixture ratio. Not only that, but also the discharge amount and balance of mixed grains, the total weight of mixed grains, etc. can be easily grasped, making it easier to manage grain coefficients.
