A stirring device and a feeding device are combined, so that evenly-stirred mixed concentrate feed directly enters the feeding system, the sum of labor is reduced, and meanwhile labor efficiency is greatly improved. A feeding motor drives a control baffle to move left and right, therefore, the size of a discharging opening in the bottom of a storage box is precisely controlled, the feed needed by each cow is discharged within a certain discharging time, and waste of the feed is reduced. The mixed concentrate feed stirring and feeding all-in-one machine can also be used in the fields of breeding beefs, pigs and the like and has high practical value.
Description
Technical field
The present invention relates to livestock-raising technical field, be specifically related to a kind of milk cow mixed concentrate and stir all-in-one of feeding.
Background technology
In the actual breeding process of milk cow, the feed of milk cow mainly comprises roughage, mixed concentrate and succulent food three kinds.Wherein mixed concentrate is very important part in milk cow dietary structure, not only provides the daily energy requirement of milk cow, and supplementary protein and growth needed for various trace elements.Mixed concentrate is by the feed of cereals, bran, puffed soybean, mineral matter, feed of animal origin, rumen buffering agents and additive premix Homogeneous phase mixing according to a certain percentage, in Powdered.
In the process that dairy cow farm is in the past fed, usually first the various compositions in mixed concentrate are mixed and manually mix together, plant with good conditionsi can utilize mechanical means to mix, then the feed mixed is contained on the truck of movement, then is transported to milk cow crib place and carries out artificial throwing and raise.So not only the amount of labour is large but also operating efficiency is very low.In addition, because the physique of each milk cow exists individual difference, required forage volume is different, manually throw in the process of raising throw the amount of raising be staff's rough estimate, this there will be phenomenon on the high side or on the low side with regard to causing throwing the amount of raising, the meeting on the high side of the throwing amount of raising causes wastes greatly, measures milk cow on the low side and does not have enough to eat milk yield also can be made to reduce greatly.Only have and suitable forage volume is all dropped into each cow head, just can improve milk yield to greatest extent, increase cultivation income.
For a long time, Chinese scholars all constantly puts forward various plans, and some scientific research institutions and company also carry out large quantity research and experiment to this both at home and abroad, achieves some achievements.As the patent of invention of patent No. feed feeding cart by name disclosed in the Chinese patent of 201310715521.0, be made up of rack for electric motor car, loose agitating device, conveying auger and conveyer etc., compact conformation, flexibility is good, but the program can not control the amount of feeding accurately, the phenomenon that process of the feeding amount of there will be is on the high side or on the low side at every turn; As the utility model patent of the patent No. a kind of movable type mixing automatic weighing feeding machine by name disclosed in the Chinese patent of 201420707956.0, be made up of electrically driven truck, storage bin, weighing device, helical blade and motor etc., easy to operate and can control to throw the size of the amount of raising by weighing device according to actual needs, but the program also needs other agitating device to be configured by feed could be poured into feed in feeding machine and use, and helical feed requires high to power of motor and easily causes dust pollution.
