Traditional lifting equipment mainly includes spiral elevator, bucket elevator, belt elevator, etc. Among them, bucket elevator is widely used due to its high efficiency and small footprint.

[0003] However, traditional bucket elevators are prone to material accumulation and clogging during long-term operation. Especially during the lifting process, the accumulation of materials and dust will cause equipment performance to decline and even cause failure and shutdown. This not only affects production efficiency, but also increases the workload of maintenance and cleaning, and increases the cost of manual cleaning.

[0054] S2: The bucket 40 at the top will turn over when passing the top of the machine head 2, so that the material is poured out from the discharge port 36;

[0055] S3: When the elevator needs to be cleaned, the jet self-cleaning component is started to spray into the elevator, and the airflow lifts the material and the material is taken away by the bucket 40, thereby effectively removing the material accumulation on the barrel and the bucket belt.

[0056] The working principle and beneficial effects of the above technical solution are as follows: the self-cleaning elevator is composed of a machine head 2, a machine base 7, an ordinary machine barrel 3, an air guide cylinder 5, an inspection cylinder 6, a bucket belt 4 and a plurality of buckets 40. The machine head 2 and the machine base 7 are connected by the ordinary machine barrel 3, the air guide cylinder 5 and the inspection cylinder 6 to ensure the connectivity of each part and the transportation of the material. The bucket belt 4 is used to lift the material from the feed port 12 to the machine head 2, and the material is lifted from the feed port and transported to the discharge port 36 through the action of the bucket 40. The transmission device 1 drives the bucket belt 4 to rotate through the motor to promote the movement of the material in the system.

[0057] The overall structural design of the present invention ensures that the material can be smoothly lifted from the feed port to the discharge port, avoiding material accumulation and blockage. The present invention can be self-cleaning and has a jet self-cleaning component, which can effectively remove material accumulation inside the elevator and reduce the need for manual cleaning.

[0058] Example 2

[0059] Based on Example 1, please refer to Figure 2-Figure 14 The base 7 includes: a support frame 8, a fixed barrel 9 is fixed on the support frame 8, a tail wheel 11 is movably installed in the fixed barrel 9, a feed port 12 is arranged on both sides of the fixed barrel 9, a gas tank 13 is installed on the outer wall of the fixed barrel 9 through a gas tank mounting bracket 14, and the gas tank 13 is connected to the jet self-cleaning component, and a discharge door 15 is movably arranged at the bottom of the fixed barrel 9, and the discharge door 15 is opened and closed by buckling the handle 16. The discharge door design makes it more convenient to clean the accumulated materials and avoids failures caused by material accumulation. The gas tank is connected to the jet self-cleaning component, which improves the cleaning efficiency and enhances the independence and automation of the self-cleaning elevator.

[0060] Preferably, the driven shaft 17 is movably connected to the center of the fixed barrel 9 through a bearing 18, and the outer wall of the driven shaft 17 located in the fixed barrel 9 is fixedly sleeved with a tail wheel 11, and a speed sensor 10 is installed at the end of the driven shaft 17. The speed sensor can be installed to monitor and adjust the speed of the hoist to ensure that the equipment runs in the best working state, and the movable installation of the tail wheel ensures the smooth operation of the equipment and avoids friction and failure caused by fixation.

[0061] Preferably, the outer wall of the inspection tube 6 is provided with a detachable door panel 19, the door panel 19 is provided with a handle 20 and an observation mirror 21, a plurality of groups of pressure plates 24 are fixedly provided on the body of the inspection tube 6, a plurality of groups of door buckles 25 are fixedly provided at equal intervals on the frame of the door panel 19, the pressure plates 24 and the door buckles 25 are connected by bolts 23, and the inspection tube 6 is divided into two symmetrical groups of conveying channels 22. The detachable door panel and observation mirror design make inspection more convenient, and the operator can check the internal operation status of the elevator at any time. The connection between the pressure plate and the door buckle ensures the sealing and stability of the door panel, and avoids material leakage.

[0062] Preferably, the air guide cylinder 5 is welded by two sets of trapezoidal shells 26, a triangular piece 27 is welded inside the air guide cylinder 5 and the air guide cylinder 5 is divided into two symmetrical conveying channels 28, and an air outlet cylinder 29 is arranged at the top center of the air guide cylinder 5. This design enhances the structural strength of the air guide cylinder, and improves the guiding efficiency of the airflow by dividing the conveying channel, which helps to improve the uniform distribution of the airflow and optimize the cleaning effect. The setting of the air outlet cylinder ensures that the airflow can be effectively cleaned inside the elevator.

[0063] Preferably, the housing of the machine head 2 is welded by a left machine head cover 30, a machine head seat 31 and a right machine head cover 32. An explosion-proof port 33 is provided on the top of the left machine head cover 30, a lifting lug 34 is provided on the housing of the right machine head cover 32, an observation mirror 2 35 is installed on the housing of the right machine head cover 32, a discharge port 36 is provided at the bottom of the right machine head cover 32, an adjustable material stopper 37 is installed at the discharge port 36, a driving shaft 46 is installed in the machine head 2 through a bearing 2 45, and a head wheel 47 is fixedly sleeved on the outer wall of the driving shaft 46 located in the machine head 2, and the head wheel 47 is connected to the tail wheel 11 through a bucket belt 4. The design of the machine head cover not only improves the stability of the structure, but also facilitates the maintenance and inspection of the interior of the machine head (for example, through the observation mirror 2), the design of the discharge port optimizes the discharge smoothness of the material and avoids blockage, and the design of the lifting lug makes the lifting of the equipment more convenient, easy to install and move.

[0064] Preferably, the transmission device 1 includes: a motor bracket 39, the motor bracket 39 is fixedly connected to the head seat 31, the reduction motor 38 is installed on the motor bracket 39, the output shaft of the reduction motor 38 is fixedly sleeved with a driving sprocket 42, the end of the driving shaft 46 is fixedly sleeved with a driven sprocket 44, the driving sprocket 42 and the driven sprocket 44 are connected by a sprocket chain 43, and the sprocket cover 41 is installed on the outer wall of the head 2 by bolts. The design of the transmission system ensures that the power transmission of the equipment is efficient and stable, the cooperation of the reduction motor and the sprocket system can smoothly drive the elevator to operate, and the design of the sprocket cover protects the sprocket system, avoids interference and damage from external objects, and improves the durability of the equipment.

[0065] Preferably, the bucket 40 is made of lightweight high-strength plastic and is fixed to the bucket belt 4 at a certain interval with special bucket bolts. The bucket belt 4 adopts a fabric-reinforced rubber belt with small elongation, high strength, wear resistance, light weight, non-toxicity and odorlessness.

[0066] The working principle and beneficial effects of the above technical solution are as follows: when the reduction motor 38 is powered on, the power is transmitted to the bucket belt 4 through the sprocket chain 43, and the buckets 40 installed on the bucket belt 4 at a certain interval move along the barrel. At this time, the material enters the moving bucket 40 from the feed port 12, is filled and transferred to the head of the elevator, and when the bucket belt 4 rotates on the head wheel 47, the material is ejected from the bucket 40 under the action of centrifugal force and gravity, so that the material is discharged from the discharge port 36 along the casing.

[0067] Among them, an adjustable material blocking device 37 is provided at the discharge port 36 to reduce the backflow of materials from the down pipe of the elevator. A symmetrical saddle is installed under the head wheel 47 to prevent dust accumulation and materials from falling from the pipeline into the machine base 7. The empty bucket 40 is rotated back to the machine base 7 through the bucket belt 4, and is lifted up to unload after being filled with materials. In this way, the cycle is repeated to lift the bottom materials to the specified height for unloading, thereby achieving the purpose of vertical lifting.

[0068] The air guide cylinder 5 is installed on the inspection cylinder 6 through a flange (the installation position and quantity are determined according to needs) to keep the air pressure in the two cylinders balanced and ensure smooth loading and unloading of the bucket 40. There is a door panel 19 for observation and maintenance on the inspection cylinder 6 for use in observing and replacing the bucket 40 and the bucket belt 4.

[0069] After the elevator is used for a long time, the barrel and bucket belt of the elevator are prone to material accumulation. If the cleaning is not thorough, it may cause material mixing and produce adverse reactions. For example, when conveying feed, improper cleaning may cause different types of feed to mix, affecting the health of livestock. Therefore, by setting up the jet self-cleaning component to effectively remove the material accumulation on the barrel, bucket and bucket belt, blockage and material adhesion problems are avoided, ensuring the long-term stable operation of the elevator.

[0070] Example 3

[0071] Based on any one of Examples 1-2, please refer to Figure 15-16The jet self-cleaning component includes: a sealing shell 49, which is installed in the base 7, and one end of the sealing shell 49 is connected to the gas tank 13 through a connecting nozzle 50, and the other end of the sealing shell 49 is connected to the air flow diffuser 55 through a plurality of connecting brackets 54. The fan-shaped diffuser 51 is fixedly sleeved on the outer wall of the fan-shaped diffuser 51, and the fan-shaped diffuser 51 is a hollow structure and is connected to the sealing shell 49. A plurality of air holes 52 are provided on the fan-shaped diffuser 51, a fixed bracket 56 is fixedly connected to the inner wall of the sealing shell 49, a limiting sleeve 58 is fixedly connected to the center of the fixed bracket 56, and a torsion spring 57 is provided in the limiting sleeve 58, and an annular guide 62 is movably provided in the empty groove at the connection between the sealing shell 49 and the fan-shaped diffuser 51, and a semi-arc The blocking ring 60 is movably connected to the sealing shell 49, and the semi-arc blocking ring 60 is fixedly connected to the annular guide 62. The end of the driving rod 59 close to the limiting sleeve 58 is movably extended into the limiting sleeve 58 and is fixedly connected to the torsion spring 57. One end of the guide vane 61 is fixedly connected to the outer wall of the driving rod 59, and the other end of the guide vane 61 is fixedly connected to the semi-arc blocking ring 60. An overflow hole 67 is provided at the end of the sealing shell 49 away from the connecting nozzle 50. One end of the grid rod 64 is arranged in the overflow hole 67 and is fixedly provided with a spherical plug 65. The other end of the grid rod 64 is movably extended into the piston cylinder 53 and is fixedly connected to the piston block 63. The piston block 63 is movably arranged in the piston cylinder 53, and the piston block 63 is connected to the inner wall of the piston cylinder 53 by a connecting spring 66.

[0072] Preferably, the outer circle of the airflow diffuser 55 is serrated, and a plurality of avoidance grooves for dispersing the airflow are arranged around the grid rod 64 . The diameter of the spherical plug 65 is smaller than the diameter of the overflow hole 67 .

[0073] The working principle and beneficial effects of the above technical solution are as follows: when it is necessary to clean the inside of the elevator, by opening the gas tank 13, a part of the gas in the gas tank 13 will enter the sealing shell 49 along the connecting nozzle 50, and due to the setting of the annular guide 62 on the semi-arc blocking ring 60, half of the area of ​​the arc-shaped empty groove at the connection between the sealing shell 49 and the fan-shaped diffuser 51 will always be in a blocked state, thereby increasing the pressure of the gas when entering the fan-shaped diffuser 51 (the area is reduced and the wind pressure is increased), and due to the presence of several groups of guide blades 61, the semi-arc blocking ring 60 will be driven to rotate, so that the sealing shell 49 and the fan-shaped diffuser 51 are connected. The position of the area blocked by the arc-shaped slot at the connection is constantly changing, and due to the existence of the torsion spring 57, when the several groups of guide blades 61 drive the driving rod 59 to rotate around the limiting sleeve 58, if the wind force is greater than the elastic force of the torsion spring 57, the several groups of guide blades 61 rotate clockwise and accumulate dynamic potential energy. When the wind force is less than the elastic force of the torsion spring 57 itself plus the accumulated dynamic potential energy, the several groups of guide blades 61 will rotate counterclockwise instead, and the clockwise and counterclockwise rotation of the several groups of guide blades 61 is disordered, and the rotation speed is also constantly different, so that the gas entering the fan-shaped diffuser 51 through the connecting nozzle 50 is in a disordered state. Therefore, the airflow pressure ejected from each air hole 52 can be regarded as different, so as to achieve a wide range of airflow injection, effectively cover all parts of the elevator, and improve the cleaning efficiency and coverage area.

[0074] At the same time, another part of the gas in the gas tank 13 will apply pressure to the spherical plug 65 through the overflow hole 67 until the grid rod 64 pushes the piston block 63 to compress the connecting spring 66, and the overflow hole 67 opens. At this time, the airflow is dispersed by the spherical plug 65 and diffuses outward in a fan shape, and after hitting the airflow diffuser 55, the airflow spray range is expanded, thereby achieving all-round and dead-angle cleaning inside the elevator, significantly improving the cleaning efficiency and coverage area, and greatly improving the cleaning efficiency and area.

[0075] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
