Description

Technical Field

[0001] The utility model relates to the technical field of forage processing and dust removal, in particular to a dust removal device for peanut vine forage processing. Background Art

[0002] During the process of forage processing, dust removal treatment is usually carried out on forage to ensure the cleanliness of the forage eaten by livestock. In the prior art, a cylindrical sieve is mostly used for dust removal and screening of forage. However, the cylindrical sieve in the prior art is usually of an exposed structure. During screening, a large amount of dust is screened out, and the dust escaping into the air not only pollutes the environment, but also has a great adverse impact on the physical health of operators. Moreover, during the falling process of the dust, some dust will pass through the cylindrical sieve again and fall onto the forage, affecting the dust removal effect. Especially during the dust removal process of peanut vine forage, due to the large amount of soil carried by peanut vines and the high dust content, a large amount of dust escapes into the surrounding air when using a cylindrical sieve for dust removal, seriously damaging the surrounding environment. Therefore, there is an urgent need for a dust removal device for peanut vine forage processing that can prevent dust from escaping into the surrounding air. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a dust removal device for peanut vine forage processing, which can prevent dust from escaping into the surrounding environment, avoid environmental damage, and at the same time avoid adverse effects on the physical health of workers. In addition, it can effectively collect dust, prevent dust from entering the internal forage through the screening mesh cylinder again, and ensure the screening effect.

[0004] The utility model adopts the following technical solutions:

[0020] The following will clearly and completely describe the present utility model in conjunction with the drawings and embodiments:

[0021] As Figures 1 to 4As shown in the figure, a dust removal device for peanut vine forage processing according to the present utility model includes a housing 1. A receiving cavity is provided in the housing 1 in a through manner along its length direction. A screening mesh cylinder 2 is rotatably provided in the receiving cavity, and the rotation structure of the screening mesh cylinder 2 is the same as that of a cylindrical screen in the prior art. An arc-shaped guide plate is provided on the inner wall of the screening mesh cylinder 2 to enable the peanut vine forage to move from the inlet end to the outlet end of the screening mesh cylinder 2 as the screening mesh cylinder 2 rotates. A dust collection cavity 3 is provided on the housing 1 at the bottom of the screening mesh cylinder 2. An exhaust port is provided on one side of the bottom of the housing 1, and the exhaust port is in communication with the dust collection cavity 3. A dust collection fan 4 in communication with the dust collection cavity 3 is provided on the housing 1 above the exhaust port. During operation, the dust collection fan 4 is turned on. As the screening mesh cylinder 2 rotates, the dust will be sucked into the dust collection cavity 3 and discharged from the exhaust port, effectively avoiding the escape of dust into the surrounding air, avoiding the adverse effects on the surrounding environment and the staff, and at the same time ensuring the dust removal effect of the peanut vine and preventing the dust from entering the inside of the screening mesh cylinder 2 again.

[0022] Furthermore, in this embodiment, the dust collection cavity 3 is provided with a slope that slopes downward from the side away from the exhaust port to the side close to the exhaust port to facilitate the fall of the dust. In addition, a diversion plate 5 is preferably provided above the dust collection cavity 3. The diversion plate 5 is located in the middle of the dust collection cavity 3, and its front and rear ends are fixedly connected to the inner wall of the dust collection cavity 3. A space is left between the bottom of the diversion plate 5 and the side walls on both sides of the dust collection cavity 3 for the dust to enter the dust collection cavity 3. In addition, the diversion plate 5 has an inverted V-shaped structure so that the falling dust can smoothly enter the dust collection cavity 3 along the slope of the diversion plate 5 and enter the discharge port from the dust collection cavity 3. The setting of the diversion plate 5 can enable the dust to enter its interior from both sides of the dust collection cavity 3, not only focusing the suction of the dust collection fan 4 to collect the dust, but also reducing the disturbance of the dust collection fan 4 to the peanut vine inside the screening mesh cylinder 2, ensuring that the peanut vine moves as the screening mesh cylinder 2 rotates until it is discharged from the outlet end of the screening mesh cylinder 2.

[0023] Furthermore, a receiving box 6 is provided at the exhaust port for convenient centralized collection of the dust. A sealing plate 7 is slidably provided at the bottom of the receiving box 6 to facilitate the timed opening of the sealing plate 7 to discharge the dust from the receiving box 6. Preferably, the receiving box 6 has a transparent structure to visually observe the amount of dust inside it and facilitate regular cleaning.

[0024] Furthermore, sealing rings 8 are provided on the housing 1 at both ends of the accommodating cavity. The screening mesh cylinder 2 is rotatably connected to the sealing ring 8. The sealing rings 8 are arranged at both ends of the housing 1, which can seal the gap between the screening mesh cylinder 2 at both ends of the accommodating cavity and the accommodating cavity, preventing dust from overflowing along this place. At the same time, the suction force of the dust collection fan 4 is concentrated on both sides of the diversion plate 5 to ensure the suction effect on the dust. A cleaning rod 9 is arranged in the accommodating cavity at the top of the screening mesh cylinder 2. Cleaning bristles 10 are arranged on the cleaning rod 9. The cleaning bristles 10 are in contact with the surface of the screening mesh cylinder 2. So that as the screening mesh cylinder 2 rotates, its surface contacts the cleaning bristles 10, and the peanut seedlings stuck on the screening mesh cylinder 2 are cleaned off, preventing the clogging of the mesh holes of the screening mesh cylinder 2 and affecting the screening operation.

[0025] Among them, multiple groups of cleaning bristles 10 are arranged at intervals along the circumferential direction of the cleaning rod 9, so as to regularly replace the brushes at different positions to contact the screening mesh cylinder 2, thereby prolonging the frequency of brush replacement. Specifically, the end of the cleaning rod 9 is rotatably connected to the sealing ring 8. One end of the cleaning rod 9 passes through the corresponding sealing ring 8 movably, and a gear 11 is arranged at the passed end. An installation hole is provided on the housing 1 above the sealing ring 8. A guide rod 13 is connected in the installation hole through a spring 12. A positioning tooth plate 14 is arranged at the bottom of the guide rod 13. The rotation of the cleaning rod 9 facilitates the switching of the cleaning bristles 10 at different positions. The settings of the gear 11 and the positioning tooth plate 14 can position and fix the switched cleaning rod 9 to ensure the stability of the cleaning rod 9. Among them, the positioning tooth plate 14 is in a V-shaped structure, so that the positioning tooth plate 14 meshes with both sides of the gear 11 to ensure the stability of the cleaning rod 9.

[0026] When the utility model is in use, first start the dust collection fan 4. As the screening mesh cylinder 2 rotates, the dust will be sucked into the dust collection cavity 3 and enter the receiving box 6 from the discharge port, effectively avoiding the escape of dust into the surrounding air, avoiding the adverse effects on the surrounding environment and the staff, and at the same time ensuring the dust removal effect of the peanut seedlings and preventing the dust from entering the inside of the screening mesh cylinder 2 again. Through the setting of the cleaning rod 9, the peanut seedlings blocked in the screening mesh cylinder 2 can be cleaned off by the contact between the cleaning bristles 10 and the screening mesh cylinder 2, so as to prevent the clogging of the mesh holes of the screening mesh cylinder 2 and ensure the efficiency of screening and dust removal.
