Description
Technical Field
[0001] This utility model relates to the field of bucket elevator technology, and in particular to a cleaning device for a bucket elevator. Background Technology
[0002] Bucket elevators are a commonly used vertical conveying device in industries such as grain processing, warehousing, and logistics, and are widely used for lifting granular materials such as grains and cereals. However, during the use of bucket elevators, the materials often contain dust, small particulate impurities, and lightweight husk fragments. The presence of these impurities not only affects the quality of the material but may also adversely affect the operation of the bucket elevator, such as increasing equipment wear and reducing conveying efficiency.
[0003] Traditional bucket elevators have many shortcomings in terms of cleaning. On the one hand, due to the limitations of the equipment structure, it is difficult to effectively remove dust and small particulate impurities from materials. On the other hand, for lightweight impurities such as rice husks and chaff, traditional methods often use manual cleaning, which is not only inefficient but also increases labor costs.
[0004] Therefore, it is necessary to provide a new cleaning device for bucket elevators to solve the above-mentioned technical problems. Utility Model Content

The blower is fixedly connected inside the elevator body, and the blower's air outlet is located diagonally above the discharge port of the elevator body. The combination of the vacuum cleaner and the blower further removes light-weight impurities such as rice husks and debris from the material, improving the purity of the material.
[0009] Preferably, springs are fixedly connected to the bottom of the vibrating screen at positions corresponding to the two sets of eccentric blocks, and the bottom ends of the two sets of springs are fixedly connected to the fixed base.

[0011] Preferably, the vibrating screen has several screen holes inside, and the diameter of the screen holes is smaller than the length of the grain particles.
[0012] Preferably, the first driven pulley and the second driven pulley are the same size, which ensures the smoothness and reliability of the transmission and avoids transmission errors and vibrations caused by inconsistent pulley sizes.
[0013] Preferably, casters are fixedly connected to the bottom diagonal corners of the elevator body, and a protective cover is fixedly connected to one side of the elevator body. The protective cover protects the pulleys and belts from damage by the external environment, reducing equipment failures and maintenance costs caused by environmental factors.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0030] Please see Figures 1 to 3 A cleaning device for a bucket elevator, comprising: an elevator body 1; a motor 2 mounted at the bottom of the elevator body 1; the output end of the motor 2 fixedly connected to a rotating shaft at the bottom of the elevator body 1; a drive pulley 3 fixedly connected to a rotating shaft extending from the top of the elevator body 1; a fixed base 4 fixedly connected to the middle of the side of the elevator body 1 near the discharge port; and a vibration mechanism 5 installed between the fixed base 4 and the elevator body 1. The lifted grain is screened by the vibration mechanism 5 to remove internal dust and small particles. Impurities are removed from the fixed base 4. A pipe 6, made of flexible hose, is fixedly connected inside the fixed base 4. A collection box 7 is placed at the bottom of the elevator body 1, and the bottom end of the pipe 6 connects to the collection box 7. A cleaning mechanism 8 is installed between the discharge port of the elevator body 1 and the fixed base 4. Grain sliding out of the discharge port passes through the cleaning mechanism 8 to remove internal light-weight husk fragments. The vibration mechanism 5 includes: a vibrating screen 51, a funnel 52, a transmission rod 53, an eccentric block 54, a first driven pulley 55, and a second driven pulley 56. The elevator body 1... An inclined vibrating screen 51 is installed inside the discharge port. A funnel 52 is fixedly connected to the bottom of the vibrating screen 51, and the bottom of the funnel 52 is connected to the top of the pipe 6. Two transmission rods 53 are rotatably connected inside the vibrating screen 51, passing through both sides. An eccentric block 54 is fixedly connected to both ends of the two transmission rods 53. A first driven pulley 55 and a second driven pulley 56 are respectively installed on the ends of the two transmission rods 53 near the driving pulley 3 through universal joints. The first driven pulley 55 and the second driven pulley 56 are respectively connected to the fixed... The fixed seat 4 is fixedly connected. The driving pulley 3 and the first driven pulley 55 are rotatably connected by a belt. The first driven pulley 55 and the second driven pulley 56 are rotatably connected by a belt. The bottom of the vibrating screen 51 is fixedly connected with springs 9 at positions corresponding to the two sets of eccentric blocks 54. The bottom ends of the two sets of springs 9 are fixedly connected to the fixed seat 4. The first driven pulley 55 and the second driven pulley 56 are the same size. The vibrating screen 51 has several screen holes inside, and the diameter of the screen holes is smaller than the length of the grain particles.
[0031] It should be noted that when motor 2 starts, its output end is fixedly connected to the rotating shaft at the bottom of the elevator body 1, thereby driving the chain inside the elevator body 1 to start running. The material is loaded into the feed port at the bottom of the elevator body 1 and gradually lifted to the top as the chain moves.
[0032] When the material is lifted to the top of the elevator body 1, it enters the vibrating screen 51 in the vibration mechanism 5. The vibrating screen 51 is driven by two transmission rods 53, and eccentric blocks 54 are fixed at both ends of the two transmission rods respectively. When the driving pulley 3 drives the first driven pulley 55 to rotate through the belt, the first driven pulley 55 then drives the second driven pulley 56 and another transmission rod 53 to rotate through the belt, so that the two eccentric blocks 54 vibrate together. The spring 9 fixedly connected to the bottom of the vibrating screen 51 at the position corresponding to the eccentric block 54 not only provides the necessary vibration power for the vibrating screen, but also plays a role in buffering and stabilizing. This vibration causes the vibrating screen 51 to start screening the material, removing dust and small particulate impurities in the material through the screen holes and letting them fall into the funnel 52. The bottom of the funnel 52 is connected to the pipe 6. These impurities will eventually be discharged into the collection box 7 at the bottom of the elevator body 1.
[0033] Please see Figure 1 The cleaning mechanism 8 includes a vacuum cleaner 81 and a blower 82. The vacuum cleaner 81 is fixedly connected to the bottom of the fixed base 4. The suction port of the vacuum cleaner 81 is located below the discharge port of the elevator body 1. The blower 82 is fixedly connected inside the elevator body 1. The air outlet of the blower 82 is located diagonally above the discharge port of the elevator body 1. The air volume of the vacuum cleaner 81 and the blower 82 is less than the weight of the grain particles.
[0034] It should be noted that when the material is vibrated and screened and slides out of the discharge port of the elevator body 1, it will pass through the cleaning mechanism 8. The cleaning mechanism 8 includes a vacuum cleaner 81 and a blower 82. The blower 82 is located diagonally above the discharge port. The air blown out by its air outlet can blow out impurities such as rice husks and debris mixed in with the material. At the same time, the vacuum cleaner 81 is located below the discharge port and is used to suck up the light impurities such as rice husks and debris that are blown out. The air volume of the vacuum cleaner 81 and the blower 82 is designed to be less than the weight of the grain particles to ensure that they will not suck up or blow away the grain particles as well.
[0035] Please see Figure 1 Universal wheels are fixedly connected to the bottom diagonal of the hoist body 1, and a protective cover 10 is fixedly connected to one side of the hoist body 1.
[0036] It should be noted that casters are fixedly connected to the bottom diagonal corners of the hoist body 1, which makes the entire device easy to move and position. A protective cover 9 is also fixedly connected to one side of the hoist body 1 to protect the pulleys and belts from damage by the external environment.
[0037] The working principle of the cleaning device for the bucket elevator provided by this utility model is as follows:
[0038] When motor 2 starts, its output end is fixedly connected to the rotating shaft at the bottom of the elevator body 1, thereby driving the chain inside the elevator body 1 to start running. The material is loaded into the feed port at the bottom of the elevator body 1 and gradually lifted to the top as the chain moves.
[0039] Vibrating screen:
[0040] When the materials are lifted to the top of the elevator body 1, they will enter the vibrating screen 51 in the vibration mechanism 5;
[0041] The vibrating screen 51 is driven by two transmission rods 53. Eccentric blocks 54 are fixed at both ends of the two transmission rods respectively. When the driving pulley 3 drives the first driven pulley 55 to rotate through the belt, the first driven pulley 55 then drives the second driven pulley 56 and another transmission rod 53 to rotate through the belt, so that the two eccentric blocks 54 vibrate together. The spring 9 fixedly connected to the bottom of the vibrating screen 51 at the position corresponding to the eccentric block 54 not only provides the necessary vibration power for the vibrating screen, but also plays a role in buffering and stabilizing. This vibration causes the vibrating screen 51 to start screening materials, removing dust and small particulate impurities in the materials through the screen holes and letting them fall into the funnel 52. The bottom of the funnel 52 is connected to the pipe 6. These impurities will eventually be discharged into the collection box 7 at the bottom of the elevator body 1.
[0042] Remove light impurities:
[0043] When the material is vibrated and screened and slides out from the discharge port of the elevator body 1, it will pass through the cleaning mechanism 8;
[0044] The cleaning mechanism 8 includes a vacuum cleaner 81 and a blower 82. The blower 82 is located diagonally above the discharge port. The air blown out by its air outlet can blow out impurities such as rice husks and debris mixed in with the material. At the same time, the vacuum cleaner 81 is located below the discharge port and is used to suck up the lightweight rice husks and debris that are blown out. The air volume of the vacuum cleaner 81 and the blower 82 is designed to be less than the weight of the grain particles to ensure that they do not suck up or blow away the grain particles as well.
[0045] Equipment movement and protection:
[0046] Universal wheels are fixedly connected to the bottom diagonal corners of the hoist body 1, which makes the entire device easy to move and position. A protective cover 9 is also fixedly connected to one side of the hoist body 1 to protect the pulleys and belts from damage by the external environment.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
