DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0033] Example 1: A crushing device for cow dung fuel briquette, such as Figures 1-11As shown, it includes a crushing box 1, a crushing cylinder 101, an inner gear ring 102, a rotating frame 103, a rotating cutting shaft 104, a cutting gear 1041, a cutter 105, a fixed partition 108 and a stirring and mixing mechanism. The crushing box 1 is fixed with the crushing cylinder 101, and the cow dung is put into the crushing cylinder 101 through the crushing box 1. The crushing cylinder 101 is fixed with the inner gear ring 102, and the crushing cylinder 101 is fixed with the fixed partition 108. A circular discharge port is opened on the fixed partition 108. The rotating frame 103 is rotatably connected to the fixed partition 108. The rotating frame 1 03 is rotatably connected to a rotating cutting shaft 104, and a cutter 105 is fixed to both the rotating frame 103 and the rotating cutting shaft 104. A cutting gear 1041 is fixed to the top of the rotating cutting shaft 104, and the cutting gear 1041 is engaged with the inner gear ring 102. When the rotating frame 103 rotates, under the action of the cutting gear 1041 and the inner gear ring 102, the rotating cutting shaft 104 will rotate and cut and crush the cow dung through the cutter 105. The stirring and mixing mechanism is installed in the crushing box 1, and the stirring and mixing mechanism stirs and mixes the crushed cow dung with combustibles such as sawdust.

[0034] During processing, cow dung is put into the crushing box 1, and the cow dung slides into the crushing drum 101 through the crushing box 1. The equipment is started to rotate the rotating frame 103. When the rotating frame 103 rotates, it drives the rotating cutting shaft 104 to rotate, so that the cutting gear 1041 moves along the inner gear ring 102. The cutting gear 1041 rotates under the drive of the inner gear ring 102, and then drives the rotating cutting shaft 104 to rotate around the rotating frame 103 while rotating. The cutter 105 on the rotating frame 103 and the rotating cutting shaft 104 can cut and crush the cow dung entering the crushing drum 101, and the crushed cow dung falls downward into the stirring and mixing mechanism through the circular discharge port on the fixed partition 108.

[0035] Example 2: Based on Example 1, Figure 1-Figure 5 As shown, the stirring and mixing mechanism includes a briquetting machine 2, a ring die 201, a rotating briquetting machine 202, a supporting rotating rod 203, a rotating cylinder 3, a fixed baffle 301, a rotating partition frame 302 and a feeding assembly. The ring die 201 is fixedly connected to the briquetting machine 2, and the rotating briquetting machine 202 is rotatably connected to the ring die 201. The supporting rotating rod 203 is fixedly connected to the connecting rod of the rotating briquetting machine 202, and the rotating cylinder 3 is fixedly connected to the supporting rotating rod 203. The rotating briquetting machine 202 drives the rotating cylinder 3 to rotate through the supporting rotating rod 203. The rotating cylinder 3 is a hollow cylindrical structure, and an outlet is provided on the side of the rotating cylinder 3. The crushing cylinder 101 is fixedly connected to the fixed baffle 301, and the rotating cylinder 3 is fixedly connected to the rotating partition frame 302. The rotating partition frame 302 rotates with the rotating cylinder 3, and the feeding assembly adds wood chips to the rotating partition frame 302 through the rotating cylinder 3.

[0036] After the cow dung is added into the crushing box 1, the briquetting machine 2 is started, and the rotating briquetting 202 rotates in the ring die 201. The supporting rotating rod 203 on the connecting rod between the two rotating briquettings 202 is driven to rotate. When the supporting rotating rod 203 rotates, the rotating cylinder 3 is driven to rotate. When the rotating cylinder 3 rotates, the rotating partition frame 302 is driven to rotate. The crushed cow dung falls downward through the fixed partition 108 and is received by the fixed baffle 301. The cow dung remains between the fixed partition 108 and the fixed baffle 301. The rotating partition frame 302 During rotation, the cow dung between the fixed partition 108 and the fixed baffle 301 is pushed aside. During the rotation of the rotating partition frame 302, the feeding component will feed the wood chips into the rotating cylinder 3, and then the wood chips will move outward from the rotating cylinder 3 into the rotating partition frame 302. As the rotating partition frame 302 rotates, the wood chips will escape from the rotating partition frame 302 and enter the cow dung. As the rotating partition frame 302 continues to rotate, the wood chips will be mixed into the cow dung from the middle. The rotating partition frame 302 continues to rotate and stir, and the wood chips will be fully mixed with the cow dung.

[0037] like Figure 2-Figure 4 As shown, the feeding assembly includes a feeding barrel 106, a feeding shaft 304, a return spring 305 and a fixed oblique block 306. The feeding barrel 106 is fixedly connected to the crushing barrel 101, and wood chips are stored in the feeding barrel 106. The feeding barrel 106 is connected to the rotating barrel 3 through the rotating frame 103. The feeding shaft 304 is slidingly connected in the rotating frame 103, the feeding barrel 106, the rotating barrel 3 and the supporting rotating rod 203. A return spring 305 is provided between the feeding shaft 304 and the rotating barrel 3. One end of the return spring 305 is fixed to the bottom of the rotating barrel 3, and the other end is fixed to the bottom end of the feeding shaft 304. A fixed oblique block 306 is fixed to the crushing box 1, and the bottom end of the feeding shaft 304 is in sliding contact with the fixed oblique block 306.

[0038] When the supporting rotating rod 203 rotates, it will drive the feeding shaft 304 to rotate. When the feeding shaft 304 rotates, it will slide upward along the supporting rotating rod 203 under the action of the fixed inclined block 306 and compress the return spring 305. When the feeding shaft 304 slides upward along the supporting rotating rod 203, the outlet at the bottom of the feeding barrel 106 will be opened, so that the wood chips in the feeding barrel 106 enter the rotating cylinder 3 through the channel in the rotating frame 103, and then slide out from the outlet on the side of the rotating cylinder 3. When the feeding shaft 304 rises to the highest point along the fixed inclined block 306, as the supporting rotating rod 203 continues to rotate, the feeding shaft 304 will be out of contact with the fixed inclined block 306. Pushed by the return spring 305, the feeding shaft 304 will move along the supporting rotating rod The rotating rod 203 slides downward to reset, and at the same time presses the wood chips at the outlet of the feeding barrel 106 downward into the internal channel of the rotating frame 103. During the rotation of the supporting rotating rod 203, the feeding shaft 304 continuously moves up and down under the action of the fixed inclined block 306 and the reset spring 305 to continuously open the opening at the bottom of the feeding barrel 106, so that the wood chips in the feeding barrel 106 continuously pass through the rotating frame 103 into the rotating barrel 3, and the wood chips then enter the cow dung between the fixed baffle 301 and the fixed partition 108 from the outlet on the side of the rotating barrel 3. As the rotating partition frame 302 continuously rotates, the rotating partition frame 302 mixes the wood chips and the cow dung evenly, thereby realizing the function of adding wood chips to the cow dung and stirring it.

[0039] like Figure 5 As shown, it also includes a transmission gear 3021, a scattering turret 3022 and an outer gear ring 303. The scattering turret 3022 is rotatably connected in the rotating partition frame 302. The top of the scattering turret 3022 passes through the rotating partition frame 302 and is rotatably connected thereto. The top of the scattering turret 3022 is fixedly connected to the transmission gear 3021, and the bottom of the fixed partition 108 is fixedly connected to the outer gear ring 303. The outer gear ring 303 is sleeved on the outside of the rotating cylinder 3. The transmission gear 3021 is engaged with the outer gear ring 303. When the rotating cylinder 3 drives the scattering turret 3022 to rotate through the rotating partition frame 302, under the action of the transmission gear 3021 and the outer gear ring 303, the scattering turret 3022 rotates and beats the wood chips into the cow dung.

[0040] When the rotating partition frame 302 rotates with the rotating cylinder 3, the scattering rotary rack 3022 rotates accordingly. When the scattering rotary rack 3022 rotates around the rotating cylinder 3, the transmission gear 3021 moves around the outer gear ring 303. Driven by the transmission gear 3021, the scattering rotary rack 3022 rotates. During the rotation of the scattering rotary rack 3022, the wood chips in the rotating partition frame 302 are sent out, so that the wood chips can be dispersed inside the cow dung, so that the wood chips and cow dung can be quickly and evenly mixed.

[0041] Example 3: Based on Example 2, Figure 5As shown, it also includes a rotating baffle 3011, a blocking torsion spring 3012 and a movable push rod 3023. A circular through hole is opened on the fixed baffle 301. The rotating baffle 3011 is rotatably connected to the fixed baffle 301. The rotating baffle 3011 and the fixed baffle 301 are connected through the blocking torsion spring 3012. Under the action of the blocking torsion spring 3012, the rotating baffle 3011 blocks the circular through hole on the fixed baffle 301, and the movable push rod 3023 is fixed in the rotating partition frame 302.

[0042] During the rotation of the rotating partition frame 302, the moving push rod 3023 moves with the rotating partition frame 302. During the movement of the moving push rod 3023, it will contact the rotating baffle 3011 and push it to rotate, and the blocking torsion spring 3012 will accumulate force and deform. When the rotating baffle 3011 rotates, the circular through hole on the fixed baffle 301 is opened to allow the mixed cow dung and wood chips to fall downward from the circular through hole on the fixed baffle 301. When the moving push rod 3023 is out of contact with the rotating baffle 3011, under the action of the blocking torsion spring 3012, the rotating baffle 3011 rotates and resets and blocks the circular through hole on the fixed baffle 301 again.

[0043] like Figure 2 and Figure 3 As shown, it also includes a rotating pushing frame 107. The rotating frame 103 is fixedly connected to the rotating pushing frame 107. A shift rod is fixed to the rotating pushing frame 107. The shift rod is located above the fixed partition 108. When the rotating pushing frame 107 rotates with the rotating frame 103, the shift rod pushes the cow dung above the fixed partition 108 to prevent the cow dung from blocking the discharge port on the fixed partition 108.

[0044] When the rotating frame 103 rotates, it will drive the rotating pushing frame 107 to rotate, and the lever outside the rotating pushing frame 107 will rotate accordingly to push the crushed cow dung to move on the top of the fixed partition 108, so that the crushed cow dung will fall downward from the circular discharge port on the fixed partition 108.

[0045] like Figure 2 、 Figure 6 and Figure 7As shown, it also includes a bulk material inclined frame 4, a rotary screening frame 401, a screening baffle frame 402 and a support swivel 403. The bulk material inclined frame 4 is fixedly connected to the crushing box 1, and the bulk material inclined frame 4 is located below the fixed baffle 301. The screening baffle frame 402 is fixedly connected to the bottom of the crushing box 1. The screening baffle frame 402 is rotatably connected to the support swivel 403, and the rotary screening frame 401 is rotatably connected to the support swivel 403. The rotary screening frame 401 is located below the bulk material inclined frame 4. The rotary screening frame 401 is a frame body inclined inward, and a plurality of horizontal layers and matching inclined layers are provided in the rotary screening frame 401. There is a gap between every two adjacent horizontal layers to screen the mixed and crushed cow dung, sawdust, etc. The cow dung and sawdust falling downward through the fixed baffle 301 slide into the rotary screening frame 401 along the bulk material inclined frame 4.

[0046] like Figure 7-Figure 9 As shown, it also includes a T-shaped connecting rod 3041, a lifting sleeve 4001, an arc-shaped bar 4002, a connecting frame 404 and an arc-shaped groove 4041. The T-shaped connecting rod 3041 is fixed to the bottom of the feeding shaft 304, and the lifting sleeve 4001 is slidingly connected to the outside of the supporting rotating rod 203. The lifting sleeve 4001 is slidingly connected to the bulk material inclined frame 4 through a guide rod. The lifting sleeve 4001 is fixed to the outside of the arc-shaped bar 4002, and the connecting frame 404 is fixed to the inside of the rotary screening frame 401. The connecting frame 404 is provided with an arc-shaped groove 4041, and the arc-shaped groove 4041 is sleeved on the outside of the arc-shaped bar 4002.

[0047] The cow dung mixed with the wood chips falls down from the circular through hole on the fixed baffle 301 and falls on the bulk material inclined frame 4, and then slides down along the bulk material inclined frame 4 to the rotary screening frame 401. The mixed cow dung and wood chips fall on the horizontal layer in the rotary screening frame 401. When the feeding shaft 304 slides upward along the supporting rotating rod 203, it drives the lifting sleeve 4001 to rise through the T-shaped connecting rod 3041. When the lifting sleeve 4001 rises, the arc bar 4002 rises accordingly. When the arc bar 4002 rises, it drives the connecting frame 404 to rotate through the arc groove 4041. When the connecting frame 404 rotates, it drives the rotary screening frame 401 to rotate. When the rotary screening frame 401 rotates, the cow dung and wood chips inside it are screened, and the crushed cow dung The cow dung and sawdust are screened out from the gaps between the horizontal layers, and the stones and other debris in the cow dung continue to remain in the rotary screening frame 401. The cow dung and sawdust screened out from the rotary screening frame 401 fall down into the ring die 201, and the rotary pressing block 202 rotates and squeezes the cow dung and sawdust in the ring die 201 into shape. When the feeding shaft 304 descends, the lifting sleeve 4001 is driven to descend through the T-shaped connecting rod 3041. When the lifting sleeve 4001 descends, the arc bar 4002 descends accordingly. When the arc bar 4002 descends, it drives the connecting frame 404 and the rotary screening frame 401 to rotate in the opposite direction through the arc groove 4041. During the up and down movement of the feeding shaft 304, the rotary screening frame 401 continues to rotate in the square to screen the cow dung and sawdust.

[0048] like Figure 7 、 Figure 10 and Figure 11 As shown, it also includes a rotating frame 4011, a discharge pipe 4012, a rotating push rod 405, a fixed block 406 and a reset torsion spring 407. The bottom of the rotating screening frame 401 is fixedly connected to the rotating frame 4011, and the discharge pipe 4012 is fixedly connected to the bottom outlet of the rotating frame 4011. The discharge pipe 4012 passes through the screening baffle frame 402 and extends outward. The fixed block 406 is fixedly connected in the support ring, and the rotating push rod 405 is rotatably connected in the fixed block 406. All rotating push rods 405 can only rotate to the same side. The rotating push rod 405 and the fixed block 406 are connected by a reset torsion spring 407.

[0049] When the stones in the rotating screening frame 401 come into contact with the rotating push rod 405, the rotating push rod 405 will push the stones on the horizontal layer in the rotating screening frame 401, so that the stones in the rotating screening frame 401 gather toward the middle and fall into the rotating frame 4011, and then are discharged outward from the outlet at the bottom of the rotating frame 4011 along the discharge pipe 4012. When the rotating screening frame 401 rotates, the rotating push rod 405 moves along the gap of the rotating screening frame 401 to prevent the rotating screening frame 401 from being blocked.
