Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to a fermentation device for feed. Background Art

[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, general feed mainly refers to food for animals raised in agriculture or animal husbandry, including more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, and feed additives. Some feeds need to be fermented and matured during the processing process to facilitate better absorption by livestock. For this purpose, a fermentation equipment for feed is needed.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The utility model adopts a crushing box, a premixing box and a fermentation box. A motor seat is installed on one side of the top surface of the fixed bottom plate, and a servo motor is installed on the motor seat. A first mounting frame is fixedly installed on the fixed bottom plate, and a crushing box is fixedly installed on the first mounting frame. A second mounting frame is fixedly installed on the fixed bottom plate, and a premixing box is fixedly installed on the second mounting frame. A third mounting frame is fixedly installed on the fixed bottom plate, and a fermentation box is installed on the third mounting frame. A stirring shaft is installed in the fermentation box, and a plurality of stirring rods are evenly fixedly installed on the stirring shaft. A grinding shaft is installed in the center of the crushing box, and a grinding block is fixedly installed on the bottom end of the grinding shaft. A premixing box is installed in the premixing box. A shaft is provided, and a plurality of premixing rods are evenly fixedly installed on the premixing shaft. When in use, the user can start the electric push rod through the control panel to drive the lifting plate to move downward. A transmission shaft is installed in the center of the lifting plate, and a second bevel gear is fixedly installed at the bottom end of the transmission shaft. When the second bevel gear is meshed with the first bevel gear fixedly installed on the stirring shaft, the stirring shaft can drive the transmission shaft to rotate. A cross sliding pin is fixedly installed on the top of the transmission shaft, and the cross sliding pin is inserted in the cross sliding groove opened at the bottom end of the premixing shaft, so when the transmission shaft rotates, the premixing shaft can be driven to rotate. On the other hand, a second pulley is fixedly installed on the premixing shaft, and a first pulley is fixedly installed on the grinding shaft. A transmission belt is sleeved between the pulley and the second pulley, so the grinding shaft can be driven to rotate when the premixing shaft rotates. Therefore, when the worker introduces the feed raw materials into the inner cavity of the crushing box through the feed hopper, the introduced feed raw materials can be crushed by using the rotating grinding block and the grinding seat, and the crushed feed raw materials can be introduced into the inner cavity of the premixing box through the feed port. At this time, an appropriate amount of fermentation agent strains are introduced into the inner cavity of the premixing box through the feeding pipe, and the premixing shaft can drive the premixing rod to rotate to perform preliminary mixing and stirring of the feed raw materials and the fermentation agent strains. After the premixing is completed, the first solenoid valve installed on the connecting pipe can be opened to introduce the raw materials after the premixed strains into the inner cavity of the fermentation box, and the stirring shaft can be used to drive the stirring rod to rotate to mix and stir the feed raw materials and the fermentation agent strains. The introduced materials are rotated and stirred to improve the fermentation efficiency. In this way, multiple batches of premixed materials can be introduced into the inner cavity of the fermentation box for fermentation. After the materials are introduced, the electric push rod drives the lifting plate to reset. At this time, the first bevel gear is separated from the second bevel gear, and the premixing shaft and the grinding shaft stop rotating. During the fermentation period, only the stirring shaft needs to drive the stirring rod to rotate. In this way, a fermentation equipment for feed can use a servo motor to complete the crushing, premixing and fermentation of feed, which is beneficial to reducing the manufacturing cost of the equipment and the power consumption during use. In addition, the added fermentation agent strains and the ground feed can be quickly and evenly mixed, which is beneficial to improving the subsequent fermentation efficiency of the feed and is more practical.

In the early stage of fermentation, nitrogen can be introduced into the fermentation box through the air pipe to reduce the oxygen concentration in the fermentation box to better meet the needs of anaerobic fermentation of the feed. The heater installed in the water bath chamber can be started through the control panel to heat the water in the water bath chamber. The temperature sensor installed in the water bath chamber can monitor the changes in water temperature and achieve precise control, thereby controlling the fermentation temperature more evenly and stably, further improving the fermentation efficiency of the feed.
