Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forage processing, and more specifically, to a forage crushing device. Background Art
[0002] When raising livestock, grass is sometimes mixed into the feed for feeding. The grass needs to be crushed into crumbs and then mixed in for fermentation. The process requires the use of a crushing device.
[0003] Most of the forage crushing devices use crushing rollers to perform crushing operations. In actual operation, the forage will contact the crushing rollers in the device and pass through the crushing rollers during the crushing operation. As the work proceeds, it is inevitable that the forage will pass through the crushing rollers without being completely crushed, resulting in a small amount of large pieces of crushed materials mixed into the finished product. The degree of crushing is not up to standard, which will affect subsequent fermentation and other treatments; moreover, most common crushing devices have a simple structure and can only perform crushing activities, but there is often a lot of water in the forage. When crushing, the cell fluid in the forage flows out, which easily makes the crushed materials adhere to the crushing rollers or the inner wall of the shell, affecting the crushing process and affecting the normal discharge of forage; in addition, most simple crushing devices have only one set of crushing structures. When crushing, the finished forage is directly fed into the equipment, which puts a lot of pressure on the crushing structure. If a lot of forage is fed in at one time, it may affect the crushing process. Utility Model Content

[0044] In summary, when the overall device is in use or running:
[0045] When the device is in use, the device is connected to the outside world, and the second controller 13 is started. The cutting shaft 14 is controlled to rotate through the second controller 13, so that the cutting shaft 14 drives the cutting blade 15 to rotate, and forage is added to the feeding hopper 12. Under the guidance of the feeding hopper 12, the forage will first contact with the cutting blade 15 before entering the shell 1, and the cutting blade 15 is used for pre-crushing. The first controller 2 is controlled to work, so that the driving crushing roller 3 is rotated, and the crushing function is provided by the crushing roller 3. The forage material fed into the shell 1 contacts with the crushing roller 3 for crushing. The shielding frame 19 provides a guiding structure to divide the crushing space, so that the forage can better contact with the crushing roller 3, and the crushed grass is treated. Gravity affects the falling, and the crushed forage is guided to the screening net 4 through the guidance of the guide plate 20, and the screening net 4 contacts the forage and screens the forage. The forage that meets the size passes through the screening net 4, and then leaves from the discharge port 5 under the guidance of the bottom of the shell 1, while the forage that does not meet the standard remains on the screening net 4, and under the guidance of the inclined screening net 4, enters the return pipe 6 along one end of the screening, controls the drive motor 16 to work, and controls the drive shaft 17 to rotate, and the drive shaft 17 drives the spiral conveying blade 18 to rotate, and the spiral conveying blade 18 transports the forage in the return pipe 6 to the top, re-adds it to the shell 1, and returns to the top of the crushing roller 3 to be crushed again.
[0046] During the crushing process, the air supply fan 8 and the heater 9 are controlled to provide negative pressure, so that the external airflow is introduced and the airflow passes through the heater 9. The heater 9 dissipates heat through the internal heating wire, and the airflow is heated by the heater 9. The hot airflow enters the shell 1 through the drainage pipe 21, and first enters the diversion pipe 22 through the drainage pipe 21. After diversion, it evenly enters the shielding frame 19 for drying treatment, so that the hot airflow enters the shell 1 to dry the forage, and then is guided by the collecting cover 23 to be collected in the outlet pipe 10, and filtered through the filter net 24 to prevent the forage from leaving, so that the airflow after drying is discharged from the outlet pipe 10, and the outlet pipe 10 is protected by the ventilation net 11 to avoid being affected.
[0047] In addition, during the working interval of the equipment, the telescopic push rod 25 can be controlled to work, so that the telescopic push rod 25 controls the movement of the cleaning hanging plate 26, so that the cleaning hanging plate 26 removes the grass on the screening net 4 and pushes it to the return pipe 6 to prevent the grass from clogging the screening net 4. The inspection door 27 can also be opened to expose the interior of the shell 1, and the equipment in the shell 1 can be adjusted. The screening net 4 can be replaced as needed, and the bolt parts on the mounting frame 30 can be disassembled to remove the support frame 29, so as to replace the support frame 29 with a different screening net 4, and install and fix it with the bolt parts. After the inspection door 27 is closed, the sealing gasket 28 will provide sealing ability through the close contact with the shell 1 to prevent leakage inside the shell 1.
