DETAILED DESCRIPTION

[0016] The utility model will be further explained in connection with the drawings.

[0017] As Figs. 1 to 3The dust removal device for forage processing shown includes a body 1. Four support legs 17 are fixedly connected to the bottom of the body 1 to ensure stability. A feed hopper 5 is fixedly connected to the upper part of one side of the body 1. A roller 6 is rotatably connected inside the feed hopper 5 to perform preliminary crushing of the forage during feeding. The uniformly rotating roller 6 also ensures even feeding, preventing excessive feeding at once from causing the machine to stall. A main shaft 7 is rotatably connected inside the body 1, and two sets of blades 9 are fixedly connected to the main shaft 7. One end of the main shaft 7 passes through the body 1 and is fixedly connected to the output end of a first motor 8. A discharge port 10 is fixedly connected to the bottom of the body 1. The upper part of the other side of the body 1 is connected to the air inlet at the top of a cyclone separator 2 via a pipe and is connected to the body... A filter screen 11 is fixedly connected to the connection point of the machine body 1. A second motor 13 is also fixedly connected to the machine body 1. The output end of the second motor 13 passes through the machine body 1 and extends inward. A brush 12 is fixedly connected to the part of the machine body 1 where the output end of the second motor 13 is located. The brush 12 is positioned corresponding to the filter screen 11 and is used to clean the accumulated hay and leaf debris on the filter screen 11 to prevent hay and leaf debris from clogging the filter screen 11 and causing dust to be unable to be collected. A dust discharge port 15 is fixedly connected to the bottom of the cyclone 2 to discharge larger solid particles and impurities that are sucked in. A shut-off valve 14 is fixedly connected above the dust discharge port 15. The top of the cyclone 2 is connected to the air inlet of the blower 3 through the air duct 16. The air outlet of the blower 3 is fixedly connected to the bag collector 4.

[0018] It should be noted that in this embodiment, the cyclone 2, the blower 3, the bag collector 4, and the airlock 14 are all existing devices, and their specific structures will not be described in detail.

[0019] To save manpower while achieving uniform feeding, roller 6 is driven by a third motor 18.

[0020] In order to increase the crushing effect of forage while protecting the blades 9, the blades 9 are provided with at least two sets to share the crushing pressure. The blades 9 consist of a first blade 901 and several tail blades 902. One end of the first blade 901 is fixedly connected to the main shaft 7, and several tail blades 902 are sequentially hinged to the other end of the first blade 901.

[0021] In order to limit the range of motion of the blade 9 and prevent the blade 9 from being damaged by cross collision due to excessive movement, a limiting groove 903 is provided at the other end of the first blade 901. One end of the tail blade 902 is fixedly connected to a connecting plate 904, and the other end is also provided with a limiting groove 903. The connecting plate 904 is hinged in the limiting groove 903 and can move within the limiting groove 903.

[0022] To prevent excessive hay and leaf debris from entering the blower 3 and causing equipment damage, the filter screen 11 has a pore size of 1cm, which protects the blower without affecting the passage of dust through the filter screen 11.

[0023] The working process of this embodiment is as follows:

[0024] During operation: The first motor 8, second motor 13, third motor 18, and blower 3 are turned on. The operator then pushes the hay into the feed inlet 5. The third motor 18 drives the roller 6 to rotate, initially crushing the hay for subsequent cutting and crushing. Simultaneously, the uniformly rotating roller 6 controls even feeding, preventing excessive feeding from causing the machine to stall. After entering the machine body 1, the hay is cut and crushed by two sets of hinged blades 9. The crushed hay is then discharged from the outlet 10 under the influence of gravity and the blades 9. During this process, the blower 3 vents the contents of the machine body 1... The generated dust is drawn into the bag filter 4 through the filter screen 11 and the cyclone separator 2 for dust collection. The cyclone separator 2 can separate the drawn-in solid matter. The lighter dust enters the bag filter 4 through the induced draft fan 3, while the heavier particulate impurities are discharged through the ash discharge port 15 through the airlock 14 to prevent the heavier particulate impurities from entering the induced draft fan 3 and causing equipment damage. The filter screen 11 can prevent stems and leaves from entering the induced draft fan 3 and causing equipment damage. The brush 12 can continuously brush off the stems and leaves stuck to the filter screen 11 to prevent stems and leaves from accumulating and clogging the filter screen 11 and affecting the dust collection and treatment.
