[0002] With the development of beef cattle breeding industry, a farm usually produces a large amount of cow dung every day. The treatment of cow dung is of great significance. Usually, the cow dung can be pressed into blocks and made into fuel for secondary use. Cow dung briquetting is a technology that uses cow dung as raw material and presses it into block fuel after a series of processing. Cow dung is a rich organic fertilizer containing a large amount of carbohydrates and cellulose. Therefore, it can be used as a raw material for biomass energy. By dehydrating, drying and pressing the cow dung, it can be converted into high-efficiency fuel blocks for heating, cooking, power generation and other fields.

[0003] At present, cow dung briquetting mainly includes the steps of crushing and pressing, that is, the collected cow dung is first evenly stirred by a mixer, and the stirred cow dung is pressed into briquette, which is a preliminary processing step. However, since cow dung is mostly piled on grasslands, some dry grass stems and leaves will be entrained after the cow dung is shoveled up. When the cow dung is collected and stirred, more stem and leaf fibers will be mixed, affecting the integrity of the briquette. In addition, cow dung contains a large amount of water, which may increase the viscosity during the briquetting process, making it difficult for the cow dung to form a solid block.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, an embodiment of the utility model provides a cow dung briquetting machine, including a shell 1 and a connecting block 2, the connecting block 2 is fixedly connected to the surface of the shell 1, a feeding port 11 is opened on the surface of the shell 1, cow dung is fed from the feeding port 11, a vertical plate 21 is fixedly connected to the upper surface of the connecting block 2, and a briquetting assembly for pressing the cow dung into shape is installed on the surface of the vertical plate 21.

[0024] An adjusting component that cooperates with the pressing block component is arranged at the bottom of the connecting block 2.

[0025] A motor C4 is fixedly connected to the center of the bottom of the shell 1, and a rotating shaft 41 is fixedly connected to the output end of the motor C4. The rotating shaft 41 passes through the bottom of the shell 1 and extends into the shell 1. A stirring blade 411 is fixedly connected to the surface of the rotating shaft 41. The stirring blade 411 is spiral-shaped and is used to stir cow dung. A movable component is installed on the top of the shell 1.

[0026] Specifically, cow dung is fed into the feed port 11, and the motor C4 drives the stirring blade 411 to rotate to stir the cow dung, which is then pressed into blocks by the briquetting assembly. During the stirring period, the movable assembly is responsible for screening out a large amount of impurities such as hay in the cow dung, and at the same time drying the cow dung to ensure that the cow dung is firmly agglomerated after being pressed into blocks.

[0027] like Figure 1 and Figure 2As shown, further, in this embodiment, the movable component includes a toothed disc 42 fixedly connected to the top of the rotating shaft 41, and a toothed ring 43 is fixedly connected to the inner wall of the shell 1 near the toothed disc 42. The toothed disc 42 is connected to the toothed ring 43 through a plurality of gears B44, and the gears B44 are respectively meshed with the toothed disc 42 and the toothed ring 43, and the three form a planetary gear set. A ventilation pipe 441 is fixedly connected to the lower end of the gear B44, and a plurality of clips 442 are fixedly connected to the surface of the ventilation pipe 441. The length of the clips 442 can be determined according to the length and quantity of hay impurities mixed in the cow dung. When the hay in the cow dung is shorter and covered more densely, the density of the clips 442 on the surface of the ventilation pipe 441 can be selected to increase, so that the hay impurities can be better filtered out. A drying component for blowing dry the cow dung is also included.

[0028] The drying assembly includes a fixing part 45 fixedly connected to the top of the outer shell 1, and a connecting pipe 451 is rotatably connected to the surface of the fixing part 45 near the center position. The lower ends of the two arms of the connecting pipe 451 are rotatably connected to a plurality of gears B44, and the lower ends of the two arms of the connecting pipe 451 are connected to a plurality of gears B44 through a rotating sealing joint, so that the gear B44 can rotate at will at the lower end of the connecting pipe 451, and the connecting pipe 451 is connected to the ventilation pipe 441. A connecting pipe 452 is installed on the top of the connecting pipe 451, and the connecting pipe 452 is a rotating sealing joint, which can be externally connected to a dryer to transport drying gas. A plurality of outlet pipes 443 are arranged on the surface of the ventilation pipe 441, and an anti-blocking filter can be arranged on the surface of the outlet pipe 443 to prevent cow dung from entering and blocking the outlet pipe 443.

[0029] Specifically, the external air supply duct is connected through the connecting pipe 452. When the stirring blade 411 rotates to stir the cow dung, the toothed disc 42 is rotated synchronously, and the gear B44 is driven to rotate synchronously, so that the ventilation pipe 441 at the lower end of the gear B44 rotates. At the same time, the drying gas enters the connecting pipe 451 through the connecting pipe 452, and continues to enter the ventilation pipe 441 downward, and passes out from the outlet pipe 443, and then the drying gas is passed out from the inside of the cow dung. While the cow dung is being stirred, the cow dung is dried, thereby improving the agglomeration efficiency.

[0030] Furthermore, in this embodiment, a feeding hole 24 for the cow dung to pass through is provided at the connection between the outer shell 1 and the connecting block 2 . The feeding hole 24 is used for the stirred cow dung to pass through and then enter the connecting block 2 from the outer shell 1 .

[0031] like Figure 2 , Figure 3 and Figure 4As shown, in a further embodiment, the pressing block assembly includes a motor A22 fixedly connected to the surface of the vertical plate 21, the output end of the motor A22 is fixedly connected to a cam 221, the surface of the cam 221 is hinged with a connecting rod A222, the lower end of the connecting rod A222 is hinged with a connecting rod B223, the lower end of the connecting rod B223 is fixedly connected to a forming block 224, and the surface of the connecting block 2 is provided with a pressing hole for the forming block 224 to slide.

[0032] Specifically, the output of motor A22 drives the cam 221 to rotate, and cooperates with the connecting rod A222 and the connecting rod B223 to perform up and down reciprocating motion, thereby causing the forming block 224 under the connecting rod B223 to move up and down reciprocatingly, and the cow dung in the connecting block 2 can be continuously pressed and formed.

[0033] Among them, the surface of the vertical plate 21 is fixedly connected to the limiting block 23, and the connecting rod B223 slides in the limiting block 23. The limiting block 23 is used to limit the connecting rod B223 so that the connecting rod B223 can only move up and down, which makes it easier for the forming block 224 to press the cow dung.

[0034] Furthermore, in this embodiment, the adjustment component includes a motor B3 fixedly connected to the bottom of the connecting block 2, the motor B3 is a servo motor, and the rotation of the motor B3 cooperates with the motor A22, the output end of the motor B3 is fixedly connected to the gear A31, and the connecting block 2 is slidably connected with a baffle 33, the baffle 33 is connected to the gear A31 through a rack 32, the rack 32 is fixedly connected to the baffle 33, and the rack 32 is meshed with the gear A31, so that when the motor B3 drives the gear A31 to rotate, it will synchronously drive the rack 32 and the baffle 33 to slide in the connecting block 2, and cooperate with the pressing process of the forming block 224. When the forming block 224 is pressed down, the baffle 33 slides to the bottom of the forming block 224, and the forming block 224 presses the cow dung on the surface of the baffle 33 and forms it. After pressing, the baffle 33 is removed, and the formed cow dung is restricted by the pressing hole. The formed cow dung will be pushed off the baffle 33, and a conveyor belt can be set under the connecting block 2, and the fallen cow dung enters the conveyor belt and is transported to the next processing link.

[0035] Working principle:

[0036] When in use, the cow dung to be briquette is fed in through the feeding port 11, and the external dryer pipeline is connected through the connecting pipe 452, and the motor C4 is started. The motor C4 drives the rotating shaft 41 and the stirring blade 411 to rotate, and then the cow dung entering is stirred. At the same time, the rotation of the rotating shaft 41 causes the gear disc 42 at the upper end to rotate synchronously. With the cooperation of the gear ring 43, the gear B44 rotates correspondingly on the gear disc 42 and the gear ring 43, and revolves around the gear disc 42. The vent pipe 441 at the lower end of the gear B44 drives a plurality of clip strips 442 on the surface to rotate synchronously, which has a certain stirring effect on the cow dung. The movement of the clip strips 442 can filter out impurities such as hay mixed in the cow dung and get stuck on the clip strips 442. In this process, the drying gas enters through the connecting pipe 452, and enters the vent pipe 441 along the connecting pipe 451, and is finally discharged from the exhaust pipe 443. While the cow dung is being stirred, the exhaust drying is carried out inside the cow dung. The stirred cow dung enters the connecting block 2 through the feeding hole 24. Through the common output of the motor A22 and the motor B3, the motor A22 drives the cam 221 to rotate, and then cooperates to drive the connecting rod A222 and the connecting rod B223 to rotate back and forth. The connecting rod B223 is limited by the limit block 23, so it will drive the forming block 224 to move up and down in the pressing hole. At the same time, the output of the motor B3 will drive the gear A31 to rotate, and then drive the rack 32 meshing with the gear A31 to move, so that the baffle 33 moves back and forth in the connecting block 2. When the baffle 33 moves horizontally to the bottom of the pressing hole, the forming block 224 will be pressed down. Under the blocking action of the baffle 33, the cow dung will be pressed and formed on the surface of the baffle 33. Then the forming block 224 is lifted, and the baffle 33 also moves horizontally in the opposite direction accordingly. Under the blocking action of the pressing hole, the pressed cow dung block will fall down accordingly, completing the entire pressing and forming process.
