[0023] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only intended to explain the relevant invention and are not intended to limit the invention. For ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0025] The dust removal cage in the embodiment of the present application can be used in conjunction with a matching straw picking and crushing machine to remove dust from agricultural recyclables such as straw and rice straw that have been picked up and crushed. It can also be set upstream of a straw baler, such as in a factory-produced production line for straw-baled feed. It can also be used in other production links such as landscaping waste that require dust and soil removal.

[0026] The rotary screen in the embodiments of the present application is used to fix the dust removal screen. The fixation here can be to fix the dust removal screen to the rotary screen by bolting, bonding, or other methods known to those skilled in the art, or the dust removal screen can be fixed to the rotary screen by means of integrated molding. The function of the rotary screen in the embodiments of the present application is mainly to drive the dust removal screen to rotate, and it is not required to have a dust removal and filtering function. It is sufficient as long as it can drive the dust removal screen or a component with dust filtering function similar to the dust removal screen to rotate.

[0027] like Figure 1As shown, an embodiment of the present application provides a dust removal cage, comprising a feed port 1, a main support 2, a rotary screen 3, a dust removal wall 4 and a rotating drive mechanism 5, wherein: the rotating drive mechanism 5 comprises a transmission shaft 50 and a rotating drive member 51, the rotating drive member 51 is fixedly connected to the main support 2 and the rotary screen 3 is suspended through the transmission shaft 50, the rotating drive member 51 can drive the rotary screen 3 to rotate relative to the main support 2 through the transmission shaft 50, and the rotary screen 3 is used to fix the dust removal screen; the dust removal wall 4 is arranged below the rotary screen 3 and fixedly connected to the lower end of the main support 2, the upper opening of the dust removal wall 4 is arranged opposite to the lower opening of the rotary screen 3 and the upper opening of the dust removal wall 4 is not smaller than the lower opening of the rotary screen 3; the outlet of the feed port 1 is arranged opposite to the upper opening of the rotary screen 3, and a plurality of dust filter holes 6 are provided on the feed port 1 and the dust removal wall 4.

[0028] The rotary drive member 51 in the embodiment of the present application can be configured as follows Figure 1 The chain drive structure shown can also set the rotating drive member 51 to other forms such as a direct drive motor directly connected to the transmission shaft 50. The present application does not limit the specific implementation form of the rotating drive member 51, as long as it can drive the transmission shaft 50 to rotate and then drive the rotary screen 3 to rotate.

[0029] The above-mentioned dust removal wall 4 mainly utilizes the centrifugal force of the chopped straw and other objects that are continuously falling to give a certain centrifugal speed to perform centrifugal dust removal again. During this process, the straw and other objects will readjust their positions due to changes in acceleration, thereby increasing the dust removal effect.

[0030] An embodiment of the present application provides a dust removal cage, including a feed port, a main bracket, a rotary screen, a dust removal wall and a rotary drive mechanism, and a plurality of dust filter holes are provided on the feed port and the dust removal wall. In this way, in addition to the traditional use of the cage to filter out dust and dirt once, dust and dirt are filtered out twice in the feed port and the dust removal wall, thereby improving the dust and dirt filtering efficiency, so that the obtained chopped straw can be packaged into feed bags that can be directly used for animal husbandry.

[0031] As a preferred embodiment, Figure 1 and Figure 2 As shown, the feed port 1 includes a bottom plate 10 extending horizontally and a pipe cover 11 engaged with the bottom plate 10. The distance between the pipe cover 11 and the bottom plate 10 gradually decreases along the direction from the inlet to the outlet of the feed port 1, and the dust filter hole 6 is provided in the pipe cover 11. This arrangement can simplify the manufacturing process. Moreover, since the distance between the pipe cover 11 and the bottom plate 10 gradually decreases, the chopped straw and other materials can be dusted by the gradually increasing air pressure in the pipe and the dust filter hole 6 when passing through the feed port 1, thereby reducing the pressure of subsequent dust removal.

[0032] As a preferred embodiment, Figure 1and Figure 2 As shown, the bottom plate 10 is eccentrically arranged relative to the transmission shaft 50, so that an additional centrifugal force can be added to the chopped straw and other materials when they enter the rotary screen 3. Preferably, the rotational linear velocity direction of the rotary screen 3 can be close to or consistent with the extension direction of the bottom plate 10. The pipe cover 11 includes a connected vertical baffle 110 and a curved screen plate 111. The vertical baffle 110 is connected to one side of the bottom plate 10, and the curved screen plate 111 is connected to the other side of the bottom plate 10 and together with the vertical baffle 110 and the bottom plate 10, it forms a feed port 1. The curvature of the curved screen plate 111 gradually decreases along the direction from the inlet to the outlet of the feed port 1. The dust filter hole 6 is opened in the curved screen plate 111. This not only provides the above-mentioned effect of increasing the air pressure in the pipe, but also prevents dust from being blown to the transmission shaft, reducing the probability of equipment failure.

[0033] As a preferred embodiment, Figure 2 As shown, the bottom plate 10 is flush with the upper opening of the rotary screen 3, and the bottom plate 10 is connected to the edge of the upper opening of the rotary screen 3. This makes feeding easier.

[0034] As a preferred embodiment, the main support 2 includes a frame 20 and a top support frame 21 fixedly connected to the top of the frame 20, the rotary screen 3 includes a roller frame 30 and a hanger 31 fixedly connected to the top of the roller frame 30, the drive shaft 50 passes through the top support frame 21 and the roller frame 30 is suspended by the hanger 31, the frame 20, the roller frame 30, the top support frame 21 and the hanger 31 are all coaxially arranged and the main support 2 is covered on the outside of the rotary screen 3, and the top support frame 21 is used to set up a dust shield. In this way, a dust removal net and other structures can be added to the frame 20 for easy maintenance and use, and a top support frame 21 is added to facilitate the construction of a dust shield. The top support frame 21 can not only be provided with a dust shield, but also with components with dust filtering functions such as the dust filter screen mentioned above, thereby providing more dust filtering processes and reducing the dust content in the final product. In the embodiment of the present application, in addition to the roller frame 30 needing to be provided with a structure similar to a dust filter with a dust removal function, the top support frame 21, the hanger 31 and the frame 20 can be provided with corresponding dust blocking or dust removal panels as needed, and can be provided according to specific needs. This application does not make specific restrictions.

[0035] As a preferred embodiment, Figure 1 As shown, the frame 20 includes an upper circular beam 200, a lower circular beam 201, and a plurality of columns 202 connecting the upper circular beam 200 and the lower circular beam 201. The upper circular beam 200 is fixedly connected to the top support frame 21, and the lower end opening of the dust removal wall 4 is fixedly connected to the lower circular beam 201. This provides the main support 2 with a higher mechanical strength.

[0036] As a preferred embodiment, a reinforcing rib 203 is further connected between the upright column 202 and the upper opening of the dust removal wall 4. This can further improve the mechanical strength of the connection between the main bracket and the dust removal wall.

[0037] As a preferred embodiment, the upper opening of the dust removal wall 4 is the same size as the lower opening of the rotary screen 3. This can reduce the probability of chopped straw and the like falling from the rotary screen escaping from the dust removal wall.

[0038] As a preferred embodiment, the diameter of the dust filter holes 6 provided at the feed port 1 is not less than the diameter of the dust filter holes 6 provided on the dust removal wall 4. In this way, dust and dirt in the chopped straw and the like can be screened out step by step, and the probability of mistakenly screening out the chopped straw and the like can be reduced.

[0039] As a preferred embodiment, the dust removal wall 4 is gradually enlarged from top to bottom. This can increase the dust removal effect of the dust removal wall and prevent chopped straw and other objects from clogging in the dust removal wall.

[0040] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept.
