[0002] Alfalfa feed grinding equipment is a device used in alfalfa feed production and processing to grind alfalfa feed raw materials. It can grind alfalfa feed raw materials more finely to facilitate alfalfa feed processing. It is widely used in various alfalfa feed production and processing applications. Existing alfalfa feed grinding equipment generally uses the rotation of blades to grind raw materials. However, alfalfa feed processing requires the drying of raw materials, while the equipment can only grind the raw materials. Therefore, a drying process needs to be added after grinding the raw materials, and it is also impossible to add liquids during the grinding process, which is not conducive to the rapid processing and use of alfalfa feed. Utility Model Content
[0003] The main objective of this invention is to provide an alfalfa feed crushing device that can effectively solve the technical problems raised in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A calcining device for alfalfa feed includes a calcining tank. A drive motor is fixedly installed at the lower end of the calcining tank. A gearbox is fixedly installed inside the lower part of the calcining tank. A rotating shaft is fixedly installed at the upper end of the gearbox.

Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figures 1-3 As shown, an alfalfa feed grinding device includes a grinding tank 1. A drive motor 4 is fixedly installed at the lower end of the grinding tank 1. A speed gearbox 5 is fixedly installed inside the lower part of the grinding tank 1. A rotating shaft 6 is fixedly installed at the upper end of the speed gearbox 5. Multiple blade fixing discs 7 are fixedly sleeved on the outer side of the rotating shaft 6. Grinding blades 8 are welded to the outer side of the blade fixing discs 7. Multiple air guide holes 9 are opened on the outer side of the rotating shaft 6 between the multiple grinding blades 8. An installation block 12 is fixedly installed on the top of the outer side of the grinding tank 1. An extension installation rod 13 is movably installed on the upper end of the installation block 12. A fan box 14 is fixedly installed at the end of the extension installation rod 13 away from the installation block 12. An air guide box 15 is fixedly installed at the lower end of the fan box 14. A turbine fan 17 and a resistance heating mesh 18 are fixedly installed inside the fan box 14, and the turbine fan 17 is located above the resistance heating mesh 18.
[0019] In this embodiment, a discharge port 3 and multiple support legs 2 are fixedly installed on the bottom outer side of the crushing tank 1. The discharge port 3 is located between the multiple support legs 2 and is connected to the interior of the crushing tank 1. The support legs 2 serve to support the placement, and the discharge port 3 serves to discharge the material.
[0020] In this embodiment, the shaft of the drive motor 4 passes through the crushing tank 1 and is connected to the gearbox 5. The rotating shaft 6 is located inside the crushing tank 1. The interior of the rotating shaft 6 is a hollow structure design. The air guide hole 9 is connected to the interior of the rotating shaft 6, and the air guide hole 9 plays the role of exhausting air.
[0021] In this embodiment, two support rods 10 are fixedly installed on the inner wall of the crushing tank 1. A support collar 11 is fixedly installed at the end of the support rod 10 away from the crushing tank 1. The support collar 11 is movably sleeved on the outside of the rotating shaft 6. The support rods 10 and the support collar 11 are used to fix the top of the rotating shaft 6 to prevent the rotating shaft 6 from rotating and deviating.
[0022] In this embodiment, an electric control switch 16 is fixedly installed on the outside of the fan box 14. The electric control switch 16 is electrically connected to the turbine fan 17 and the resistance heating grid 18. The electric control switch 16 is used to control the switching of the turbine fan 17 and the resistance heating grid 18.
[0023] In this embodiment, the turbine fan 17 and the resistance heating mesh 18 are located above the air guide box 15. The air guide box 15 is fitted onto the upper end of the rotating shaft 6 and is movably connected to it. The air guide box 15 is used to guide air into the rotating shaft 6.
[0024] It should be noted that this utility model is an alfalfa feed crushing device. In use, the support bracket 2 supports and places the crushing tank 1. The operation of the drive motor 4 drives the rotating shaft 6 to rotate through the gearbox 5, which in turn drives the blade fixing plate 7 and the crushing blade 8 to rotate. The raw materials for alfalfa feed processing are put into the crushing tank 1 from the top and come into contact with the rotating crushing blade 8, so that the crushing blade 8 crushes the raw materials and then discharges them through the discharge port 3.
[0025] Power is supplied to the electric control switch 16, which in turn controls the turbine fan 17 and the resistance heating grid 18 to operate. After the resistance heating grid 18 starts running, it generates resistance and heats up. After the turbine fan 17 starts running, it rotates and then draws in air from the top of the fan box 14 and blows it downward. Therefore, the air passes through the resistance heating grid 18 and moves downward with high temperature. Then it enters the rotating shaft 6 through the air guide box 15. Finally, the high temperature air is discharged from the air guide hole 9 on the outside of the rotating shaft 6, thereby evenly delivering the high temperature air into the crushing tank 1 to contact the crushed raw materials and use the high temperature to dry the raw materials during crushing.
[0026] By extending the mounting rod 13 and rotating it around the mounting block 12, the air guide box 15 can be separated from the top of the rotating shaft 6 and removed. The liquid for alfalfa feed processing can be directly injected through the rotating shaft 6, and the liquid is also discharged through the air guide hole 9 to contact the raw material, so that the raw material can be directly mixed with the liquid for alfalfa feed processing when it is crushed.
[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
