[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A forage screening device for dairy cows includes a base plate 1, a screening component 2 fixedly connected to the upper end of the base plate 1, a connecting component 3 sleeved on the upper end of the screening component 2, a first collection box 4 and a second collection box 5 inserted through the lower right end of the screening component 2, with the second collection box 5 located below the first collection box 4, a first pull ring 6 fixedly connected to the middle right end of both the first collection box 4 and the second collection box 5, two support blocks 7 fixedly connected to the upper left and upper right ends of the screening component 2 and the lower left and lower right ends of the connecting component 3, and a fixing screw 8 inserted through the upper end of each of the four sets of longitudinal support blocks 7, and a feed frame 10 fixedly connected through the upper end of the connecting component 3;
[0025] In this embodiment, a support plate 9 is fixedly connected to the lower left end of the feeding frame 10, and a motor 12 is fixedly connected to the upper end of the support plate 9. A support rod 13 is fixedly connected to the part of the output end of the motor 12 located in the inner frame of the feeding frame 10. The right end of the support rod 13 is movably connected to the inner frame wall of the feeding frame 10 through a connecting shaft. Several stirring rods 14 are fixedly connected to the outer surface of the support rod 13 in a circular array. Several limiting rods 11 are fixedly connected to the inner frame wall of the connecting assembly 3, and the several limiting rods 11 are staggered. The several stirring rods 14 do not contact the inner frame wall of the feeding frame 10.
[0026] The above scheme involves connecting the connecting component 3 to the four insert rods 26, and then using four fixing screws 8 to pass through the four sets of longitudinal support blocks 7. This allows the connecting component 3 and the screening component 2 to be fixedly connected together, improving stability. The connection, installation, and disassembly between the connecting component 3 and the screening component 2 are also convenient. The feeding frame 10 facilitates the falling of the forage. The motor 12 drives the support rod 13 to rotate, which in turn drives several stirring rods 14 to rotate, thus stirring the forage falling through the feeding frame 10 and separating the forage. Several limiting rods 11 slow down the falling of the forage, facilitating the subsequent forage screening process.
[0027] In this embodiment, the screening component 2 includes a screening frame 21. Three receiving plates 22 are fixedly connected at equal intervals along the right end of the screening frame 21. Three No. 3 collection boxes 23 are interspersed at equal intervals along the right end of the screening frame 21. A No. 2 pull ring 24 is fixedly connected to the right end of each of the three No. 3 collection boxes 23. A positioning block 25 is fixedly connected to the lower front side of the right end of each of the three No. 3 collection boxes 23. The three No. 3 collection boxes 23 are located on the upper part of the three receiving plates 22. Insert rods 26 are fixedly connected to the four corners of the upper end of the screening frame 21. A filter screen 27 is fixedly connected to the left side of the lower inner frame wall of the screening frame 21. Three discharge troughs 2 are opened at equal intervals along the right end of the screening frame 21. 9. Three slots 28 are equally spaced longitudinally on the right end of the screening frame 21. Three discharge slots 29 are located on the upper part of the three slots 28. Two connecting slots 30 are opened on the lower right end of the screening frame 21. Three fixing plates 31 are fixedly connected to the left frame wall inside the screening frame 21. Two fans 32 are fixedly connected to the right end of each of the three fixing plates 31. The two fans 32 in the three sets of transverse directions are located on the left side of the filter screen 27. The screening frame 21 is fixedly connected to the base plate 1. The connecting component 3 is sleeved with the four insert rods 26. The three No. 3 collection boxes 23 are respectively inserted and connected to the three slots 28. The two connecting slots 30 are respectively sleeved with the No. 1 collection box 4 and the No. 2 collection box 5.
[0028] The above scheme involves connecting three No. 3 collection boxes 23 to three slots 28, and then connecting them to three receiving plates 22 via pins passing through three positioning blocks 25. This positions the three No. 3 collection boxes 23. The filter screen 27 protects the three sets of horizontal fans 32 during operation, preventing the feed from tangling with them. The three sets of horizontal fans 32 can blow light feed, which is then discharged through three discharge troughs 29, ultimately... The forage falls into three No. 3 collection boxes 23 for collection, improving stability. The No. 1 collection box 4 is inserted and connected to the upper connecting groove 30, and the No. 2 collection box 5 is inserted and connected to the lower connecting groove 30. The lower wall of the No. 1 collection box 4 has filter holes, and the lower wall of the upper connecting groove 30 also has several filter holes. During the forage screening process, the dust falls first and falls into the No. 2 collection box 5 through these filter holes for collection. The screened forage is collected through the No. 1 collection box 4.
[0029] It should be noted that this utility model is a forage screening device for dairy cows. During use, the connecting component 3 is sleeved on the four insert rods 26, and four fixing screws 8 pass through the two longitudinal support blocks 7 of the four sets to achieve a fixed connection between the connecting component 3 and the screening component 2. This connection method ensures the stability of the overall structure of the device; and it is convenient to operate when disassembly is required, and can be flexibly adjusted according to actual needs. For fixing the collection boxes, the three No. 3 collection boxes 23 are respectively inserted into the three slots 28, and then the pins pass through the three positioning blocks 25 and are inserted into the three receiving plates 22 to complete the positioning of the No. 3 collection box 23; the No. 1 collection box 4 is inserted into the upper connecting groove 30, and the No. 2 collection box 5 is inserted into the lower connecting groove 30 to realize the installation and fixation of each collection box, ensuring that the position of the collection box is stable during the screening process. The forage falls through the feed frame 10, the motor 12 drives the support rod 13 to rotate, and then the several stirring rods 14 rotate accordingly. The stirring rods 14 stir the falling forage. The process involves stirring to separate tangled forage, making it more loosely distributed. Several limiting rods 11 slow down the falling speed of the forage, allowing time for subsequent screening and making the screening process more thorough and effective. The filter screen 27 protects the two horizontal fans 32 of the three sets, preventing the forage from tangling with the fans 32 during screening and ensuring the normal operation of the fans 32. When the forage falls in the screening frame 21, the two horizontal fans 32 of the three sets start working. The wind generated by the fans 32 blows the light forage towards the discharge chute 29 and out through the discharge chute 29, eventually falling into the three No. 3 collection boxes 23 for collection, avoiding waste of forage. During the forage screening process, the lighter dust falls first, passing through the filter holes on the screening frame 21 and falling into the No. 2 collection box 5 below for collection. The forage that meets the requirements continues to fall and is eventually collected by the No. 1 collection box 4. In this way, the forage is effectively screened and classified for collection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
