Description

Technical Field

[0001] This utility model relates to the field of manual gate technology, specifically a novel fully sealed manual gate. Background Technology

[0002] In today's mining industry, manual slide gate valves are a commonly used type of gate valve, typically installed at the bin opening. They are widely used due to their stable structure and low cost. Existing manual slide gate valves generally consist of the chute body, gate frame, roller assembly, slide gate, rack, gear, shaft, and handwheel. For example, patent publication number CN218344394U discloses a fully sealed manual slide gate valve device, showing that the operator manually turns the handwheel, which drives the gear to rotate. The gear meshes with the rack, causing it to move, which in turn causes the slide gate to slide on the roller assembly. However, these gates are usually installed at higher bin openings, requiring operators to use platforms or ladders to operate them, increasing infrastructure costs. Furthermore, manual gates lack self-locking functionality, making operation inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of fully sealed manual gate. The manual gate is opened and closed by pulling a ring zipper, eliminating the need for a platform ladder, reducing infrastructure costs, and making it easy to operate. It is also convenient to observe and judge the degree of opening and closing of the gate. The manual gate has a self-locking function, good stability of gate opening and closing, good sealing effect, and high environmental performance. It can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel fully sealed manual gate includes a chute body, a gate frame, a roller assembly, a gate plate, and a rotating shaft. The gate frame is vertically installed on the cross-section of the chute body. The roller assembly is parallel to the gate frame and is located on both sides inside the gate frame. The gate plate can move smoothly along the direction of the roller assembly. The rotating shaft is located in the middle of the gate frame and has a gear. The bottom end of the gate plate has a rack that meshes with the gear. One end of the rotating shaft extends through the outside of the chute body and is equipped with a coupling. A manual chain puller is fixedly installed on the chute body at the position corresponding to the coupling, and the output shaft end of the manual chain puller is fixedly connected to the rotating shaft through the coupling. The gate frame also includes a sealing cover, which is used to enclose and seal the gate frame, the gate plate, the rack, and the gear.

[0005] Furthermore, the manual zipper includes a worm gear reducer fixed on the chute body, a sprocket connected to the worm shaft end of the worm gear reducer, an annular zipper on the sprocket, and the worm shaft end of the worm gear reducer connected to a coupling; pulling the annular zipper can drive the rotating shaft to rotate, causing the gate plate to open and close.

[0006] Furthermore, the outer end of the gate plate is provided with a travel indicator ruler along its sliding direction. The outer end of the travel indicator ruler extends through the gate frame, and the outer end of the travel indicator ruler is provided with multiple color markings of different colors along its length.

[0007] Furthermore, a sealing ring is provided at the outer end of the gate frame at the position corresponding to the travel indicator, and the inner hole structure of the sealing ring is adapted to the outer edge contour structure of the travel indicator, and the outer indicating end of the travel indicator slides and is nested in the sealing ring.

[0008] Furthermore, the sealing cover includes an upper sealing plate, a lower sealing plate, and a side sealing frame. The upper sealing plate is fixed to the upper half of the gate frame; the side sealing frame is fixed between the inner walls of both sides of the chute body, the top of the side sealing frame is fixed to the lower part of the gate frame, and the side sealing frame is used to wrap the gear; the lower sealing plate is installed in the lower half of the gate frame, and the end of the lower sealing plate is fixed to the side sealing frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This new fully sealed manual gate allows operators to drive the gate plate to open and close by pulling the ring chain of the manual chain puller. The length of the ring chain can be determined according to the installation height of the gate, making it convenient for personnel to operate. Operators can operate it from the ground without the need for a platform or ladder, thus reducing infrastructure costs. The stroke indicator makes it easy to observe and judge the opening and closing degree of the gate. The worm gear reducer of the manual chain puller has a self-locking function, preventing the gate plate from moving on its own, resulting in good gate opening and closing stability. The sealing cover provides an overall seal for the manual gate, preventing dust leakage when materials flow through the chute body, resulting in good sealing effect and high environmental performance.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1-3 This utility model provides a technical solution: a novel fully sealed manual gate, comprising a chute body 1, a gate frame 2, a roller assembly 21, a gate plate 3, and a rotating shaft 4. The gate frame 2 is vertically installed on the cross-section of the chute body 1. The roller assembly 21 is parallel to the gate frame 2 and is located on both sides inside the gate frame 2. The gate plate 3 can move smoothly along the setting direction of the roller assembly 21. The rotating shaft 4 is located in the middle of the gate frame 2. A gear 41 is provided on the rotating shaft 4. A rack 31 that meshes with the gear 41 is provided at the bottom end of the gate plate 3. One end of the rotating shaft 4 extends through the outside of the chute body 1 and is provided with a coupling 5. A manual chain puller 6 is fixedly provided on the chute body 1 at the position corresponding to the coupling 5, and the output shaft end of the manual chain puller 6 is fixedly connected to the rotating shaft 4 through the coupling 5.

[0020] The manual zipper 6 includes a worm gear reducer 61 fixed on the chute body 1. The worm shaft end of the worm gear reducer 61 is connected to a sprocket 62. The sprocket 62 is provided with an annular zipper 63. The worm shaft end of the worm gear reducer 61 is connected to a coupling 5.

[0021] In use: the operator pulls the annular zipper 63 to rotate the sprocket 62, which in turn drives the worm shaft of the worm gear reducer 61 to rotate. The worm shaft of the worm gear reducer 61 drives the rotating shaft 4 and gear 41 to rotate. The gear 41 meshes with the rack 31, causing the gate plate 3 to move smoothly along the direction of the roller assembly 21, thereby controlling the opening and closing of the gate plate 3. Due to the characteristics of the worm gear reducer 61, it can only drive the worm wheel to rotate, not the other way around. Therefore, the position of the gate plate 3 will not move after the sprocket 62 stops rotating, achieving a self-locking effect. The length of the annular zipper 63 can be determined according to the installation height of the gate, making it convenient for personnel to operate. Operators can operate it from the ground without the need for a platform or ladder, thus reducing infrastructure costs.

[0022] Please refer to the following: Figure 4-5 It also includes a sealing cover 7 provided on the gate frame 2. The sealing cover 7 includes an upper sealing plate 71, a lower sealing plate 72, and a side sealing frame 73. The upper sealing plate 71 is fixed to the upper half of the gate frame 2; the side sealing frame 73 is fixed between the inner walls of both sides of the chute body 1, and the top of the side sealing frame 73 is fixed to the lower part of the gate frame 2, and the side sealing frame 73 is used to wrap the gear 41; the lower sealing plate 72 is installed on the lower half of the gate frame 2, and the end of the lower sealing plate 72 is fixed to the side sealing frame 73; by sealing the gate frame 2, the insert gate plate 3, the rack 31, and the gear 41 with the sealing cover 7, the dust does not leak out when the material flows through the chute body 1, which achieves a good sealing effect, making the entire gate a fully sealed environmentally friendly manual gate.

[0023] Please refer to the following: Figure 6-7 The outer end of the gate plate 3 is provided with a travel indicator 8 along its sliding direction. The outer end of the travel indicator 8 extends through the gate frame 2, and the outer indicating end of the travel indicator 8 is provided with multiple color markings of different colors along its length. The outer end of the gate frame 2 is provided with a sealing ring 9 at the position corresponding to the travel indicator 8, and the inner hole structure of the sealing ring 9 is adapted to the outer edge contour structure of the travel indicator 8. The outer indicating end of the travel indicator 8 is slidably nested in the sealing ring 9. When the gate plate 3 is opened and closed, the operator judges the degree of opening and closing of the gate plate 3 by observing the length of the different colors of the travel indicator 8 that are exposed. The travel indicator 8 is slidably sealed by the sealing ring 9.

[0024] The novel fully sealed manual gate disclosed in this embodiment allows operators to open and close the gate plate 3 by pulling the annular chain 63 of the manual chain puller 6. The length of the annular chain 63 can be determined according to the installation height of the gate, facilitating operation and allowing operators to operate from the ground without the need for a platform or ladder, thus reducing infrastructure costs. The worm gear reducer 61 of the manual chain puller 6 has a self-locking function, preventing the gate plate 3 from moving on its own, ensuring good gate opening and closing stability. The manual gate is completely sealed by the sealing cover 7, preventing dust leakage when materials flow through the chute body 1, resulting in good sealing performance and high environmental protection performance.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
