Description

Technical Field

[0001] This utility model belongs to the technical field of grain storage equipment, and in particular relates to a ventilated floor cage for grain storage. Background Technology

[0002] A ventilated granary duct is a ventilation system specifically designed for grain warehouses. It aims to effectively ventilate and exchange air for the grain through underground ventilation ducts. Its main purpose is to maintain air circulation within the warehouse, prevent moisture accumulation, ensure the quality of the grain is not compromised, and avoid problems such as mold and pests.

[0003] According to a public notice (publication number: CN 210275174U), a ventilation cage for grain storage is formed by overlapping a main cage and branch cages connected to the main cage. The cross-sections of the main cage and the branch cages are both arc-shaped. Ventilation holes are provided on the surface of the branch cages. Ventilation holes are evenly distributed on the surface of the main cage. Overlapping cage grooves are provided at both ends of the main cage and both ends of the branch cages.

[0004] In the aforementioned application, the cooperation between the main cage and the ventilation hole assembly makes it difficult to clean the surface of the cage when it is used in the grain warehouse. This leads to the accumulation of debris on the surface of the cage after long-term use, causing blockage. Therefore, we propose a ventilated cage for grain warehouses. Utility Model Content

[0005] The purpose of this invention is to provide a ventilation cage for grain silos. Through the coordinated operation of components such as the motor, cleaning brushes, and return springs in the anti-clogging mechanism, starting the motor drives the threaded rod to rotate, which in turn moves the push rod and the force-bearing rod, pushing the cleaning brushes to clean the ventilation ducts. The movement of one cleaning brush simultaneously pushes another, ensuring thorough cleaning of the inner and outer walls of the ventilation ducts. The orderly movement of multiple cleaning brushes achieves a comprehensive cleaning effect on the ventilation ducts, effectively preventing dust accumulation, ensuring unobstructed ventilation, improving ventilation efficiency and air quality in the grain silo, and solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a ventilated ground cage for grain storage, including a ventilation box, a ventilation duct fixedly connected to the side of the ventilation box, and an anti-blocking mechanism provided inside the ventilation box;

[0008] The anti-clogging mechanism includes a motor, which is fixedly connected inside the ventilation box. A threaded rod is fixedly connected to the output end of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A push rod is fixedly connected to the top of the threaded sleeve. A force-bearing rod is slidably connected through the side of the ventilation duct. A cleaning brush is fixedly connected to the end of the force-bearing rod away from the push rod.

[0009] Furthermore, a return spring is fixedly connected to the side of the ventilation duct, and the end of the return spring away from the side of the ventilation duct is fixedly connected to the side of the cleaning brush. The purpose of this is to ensure that the cleaning brush can automatically reset and reduce manual intervention.

[0010] Furthermore, a limiting plate is fixedly connected inside the ventilation box. The side of the limiting plate penetrates the circumferential surface of the threaded rod. A limiting shaft is fixedly connected to the side of the limiting plate. The circumferential surface of the limiting shaft penetrates and slides through the side of the threaded sleeve. The purpose of this is to limit the displacement distance of the threaded sleeve and prevent rotation during the movement of the threaded sleeve.

[0011] Furthermore, the side of the force-bearing rod is located on the displacement trajectory of the push rod, and the force-bearing rod, cleaning brush and return spring are arranged in a number of units and are linearly arrayed along the side of the ventilation duct. The purpose is to ensure that the movement of the push rod can push the force-bearing rod.

[0012] Furthermore, the ventilation box is equipped with an enhanced airflow mechanism, which includes a rotating shaft. The rotating shaft is fixedly connected to the end of the threaded rod away from the motor output end. A ventilation fan blade is fixedly passed through the circumferential surface of the rotating shaft, and a bevel gear is fixedly passed through the circumferential surface of the rotating shaft. A fixing plate is fixedly connected inside the ventilation box, and a control shaft is fixedly passed through the side of the fixing plate. A bevel gear is fixedly passed through the circumferential surface of the control shaft, and a second ventilation fan blade is fixedly passed through the circumferential surface of the control shaft. The purpose of this is to enhance the ventilation velocity and increase the ventilation effect.

[0013] Furthermore, there are two of the fixed plate, control shaft, and bevel gear II, which are symmetrical to each other along the vertical central axis of the ventilation box, in order to ensure improved ventilation efficiency.

[0014] Furthermore, the circumferential surface of the first bevel gear meshes with the circumferential surface of the second bevel gear, the purpose of which is to ensure that the rotation of the first bevel gear can drive the second bevel gear to rotate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model utilizes the coordinated operation of components such as the motor, cleaning brush, and return spring in the anti-clogging mechanism. Upon starting the motor, the threaded rod rotates, which in turn moves the push rod and the force-bearing rod, propelling the cleaning brush to clean the ventilation duct. The movement of one cleaning brush simultaneously drives another, ensuring thorough cleaning of the inner and outer walls of the ventilation duct. The orderly movement of multiple cleaning brushes achieves a comprehensive cleaning of the ventilation duct, effectively preventing dust accumulation, ensuring unobstructed ventilation, and improving ventilation efficiency and air quality in the grain storage area.

[0017] 2. This utility model enhances the interaction between components such as the ventilation fan blade one, control shaft, and ventilation fan blade two in the enhanced wind power mechanism. The rotation of the threaded rod drives the rotating shaft, which in turn drives the ventilation fan blade one to rotate, increasing the airflow. The rotating shaft also drives bevel gear one and bevel gear two to mesh, thereby driving the control shaft and ventilation fan blade two to rotate, enhancing the wind power output. Through this chain reaction, the wind power in multiple ventilation ducts is enhanced. This design achieves the effect of enhancing the wind power inside the ventilation ducts, improving ventilation efficiency, and ensuring smooth air circulation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model is a ventilated cage for grain storage, including a ventilation box 1, a ventilation duct 2 fixedly connected to the side of the ventilation box 1, and an anti-blocking mechanism 3 provided inside the ventilation box 1.

[0028] The anti-clogging mechanism 3 includes a motor 31, which is fixedly connected inside the ventilation box 1. A threaded rod 32 is fixedly connected to the output end of the motor 31. A threaded sleeve 33 is threadedly connected to the circumferential surface of the threaded rod 32. A push rod 34 is fixedly connected to the top of the threaded sleeve 33. A force-bearing rod 35 is slidably connected through the side of the ventilation duct 2. A cleaning brush 36 is fixedly connected to the end of the force-bearing rod 35 away from the push rod 34.

[0029] As shown in the figure, a return spring 37 is fixedly connected to the side of the ventilation duct 2. The end of the return spring 37 away from the side of the ventilation duct 2 is fixedly connected to the side of the cleaning brush 36. The purpose is to ensure that the cleaning brush 36 can automatically reset and reduce manual intervention.

[0030] As shown in the figure, a limiting plate 38 is fixedly connected inside the ventilation box 1. The side of the limiting plate 38 penetrates the circumferential surface of the threaded rod 32. A limiting shaft 39 is fixedly connected to the side of the limiting plate 38. The circumferential surface of the limiting shaft 39 penetrates and slides through the side of the threaded sleeve 33. The purpose is to limit the displacement distance of the threaded sleeve 33 and prevent the threaded sleeve 33 from rotating during movement.

[0031] As shown in the figure, the side of the force rod 35 is located on the displacement trajectory of the push rod 34. There are several force rods 35, cleaning brushes 36 and return springs 37, which are arranged in a linear array along the side of the ventilation duct 2. The purpose is to ensure that the movement of the push rod 34 can push the force rod 35.

[0032] As shown in the figure, the ventilation box 1 is equipped with an enhanced airflow mechanism 4. The enhanced airflow mechanism 4 includes a rotating shaft 41, which is fixedly connected to the end of the threaded rod 32 away from the output end of the motor 31. A ventilation fan blade 42 is fixedly passed through the circumference of the rotating shaft 41, and a bevel gear 43 is fixedly passed through the circumference of the rotating shaft 41. A fixing plate 44 is fixedly connected inside the ventilation box 1. A control shaft 45 is fixedly passed through the side of the fixing plate 44. A bevel gear 46 is fixedly passed through the circumference of the control shaft 45, and a ventilation fan blade 47 is fixedly passed through the circumference of the control shaft 45. The purpose is to enhance the ventilation velocity and increase the ventilation effect.

[0033] As shown in the figure, there are two sets of fixed plate 44, control shaft 45 and bevel gear 46, which are symmetrical to each other along the vertical central axis of ventilation box 1, in order to ensure improved ventilation efficiency.

[0034] As shown in the figure, the circumferential surface of bevel gear 43 meshes with the circumferential surface of bevel gear 46. The purpose of this is to ensure that the rotation of bevel gear 43 can drive the rotation of bevel gear 46.

[0035] A specific application of this embodiment is as follows: When the ventilation duct 2 is in daily use in the grain warehouse, the operator can start the motor 31. The output end of the motor 31 starts to rotate, driving the threaded rod 32 to rotate. The rotation of the threaded rod 32 drives the threaded sleeve 33 to move linearly through the limiting shaft 39. The movement of the threaded sleeve 33 then drives the push rod 34 to move. The movement of the push rod 34 pushes the force rod 35. The movement of the force rod 35 further drives the cleaning brush 36 to move linearly, cleaning the outer wall of the ventilation duct 2. During the movement of the cleaning brush 36, it also pushes another force rod 35, thereby driving another cleaning brush 36 to move, thus achieving multi-point cleaning of the inner wall of the ventilation duct 2. Through this working sequence, multiple cleaning brushes 36 move in an orderly manner, ensuring the comprehensive cleaning of the ventilation duct 2, avoiding the accumulation of dust or debris, and ensuring the smooth operation of the ventilation duct 2. When the push rod 34 leaves the side of the force rod 35, the multiple cleaning brushes 36 are automatically reset by the return spring 37.

[0036] As the threaded rod 32 rotates, it drives the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 drives the ventilation fan blade 42 to rotate, thereby increasing the airflow and improving the ventilation effect. At the same time, the rotation of the rotating shaft 41 also drives the bevel gear 43 to rotate. The bevel gear 43 meshes with the bevel gear 46, and the meshing causes the bevel gear 46 to rotate, which in turn drives the control shaft 45 to rotate. The rotation of the control shaft 45 further drives the ventilation fan blade 47 to rotate, enhancing the airflow output of the ventilation system. Through this chain reaction, the airflow of multiple ventilation ducts 2 is enhanced, improving the overall ventilation effect and ensuring smoother air circulation.
