Description

Technical Field

[0001] This utility model relates to the field of electric shovel bucket technology in mining, and in particular to an electric shovel bucket device with a buffer bucket door. Background Technology

[0002] During the opening and closing of the bucket door in a mining electric shovel bucket, it generally relies on its own weight. When the bucket is in a vertical position, the door is pressed tightly against the bucket body by its own weight. When the bucket is raised to a certain angle, the door moves vertically downwards by its own weight, separating from the bucket body at a certain angle, thus opening the door. However, the opening and closing process is often accompanied by violent swaying and vibration. Over time, this can cause loosening of the hinge point between the door and the bucket body, and can cause significant damage to the bucket door and the parts of the bucket body in contact with it. Furthermore, the sudden change in the angular velocity of the moving parts generates a huge angular momentum. This angular momentum further generates a strong reaction torque, which is transmitted through the hinge point to the bucket body and even the entire boom system. This repeated impact not only leads to fatigue damage to the connecting parts but also causes severe vibration of the entire equipment, reducing stability and shortening the lifespan of related structural components.

[0003] In the existing technology, friction plates are installed at the hinge between the bucket gate and the bucket body to play a buffering role. However, this method causes more serious damage to the friction plates. Furthermore, since the friction plates are located on the inside of the hinge, it is not easy to observe the wear of the friction plates. Moreover, the replacement process of the friction plates is quite cumbersome. Utility Model Content

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an electric shovel bucket device with a buffer gate, wherein the gate is connected to a linear guide rail set on the top of the bucket body through a connecting rod. The linear guide rail is provided with elongated holes and end caps to achieve the buffering effect while making the buffer part easy to observe and replace.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include: An electric shovel bucket device with a buffer gate includes a bucket body and a gate. A first hinge seat is fixedly provided on the top of the gate. The gate is hinged to the first hinge seat via a gate connecting rod. The gate connecting rod is hinged to a connecting rod. The other end of the connecting rod is slidably and frictionally connected to a linear guide rail. A buffer element is provided on the linear guide rail. The buffer element is located at both ends of the sliding stroke of the connecting rod on the linear guide rail during the opening and closing of the gate.

[0006] Furthermore, two sets of combined connection structures for the gate connecting rod, the first hinge seat, the connecting rod, and the linear guide rail are provided, symmetrically arranged on the top of the gate near the gate on one side.

[0007] Furthermore, one end of the connecting rod near the sluice gate is hingedly connected to a second hinge seat provided on the sluice gate connecting rod.

[0008] Furthermore, the connecting rod is arc-shaped.

[0009] Furthermore, a guide rod is detachably connected to the linear guide rail.

[0010] Furthermore, the linear guide rail is provided with two parallel guide rods.

[0011] Furthermore, the linear guide rail has a U-shaped housing, the bottom of which is fixedly connected to the top of the bucket body. Guide rods are provided on both sides of the U-shaped housing, and a guide rod inlet and outlet are opened at the end of the U-shaped housing away from the bucket door. Guide rail end caps are detachably connected to the outside of the guide rod inlet and outlet.

[0012] Furthermore, an elongated hole is provided on the side wall of the linear guide rail, which corresponds to the position of the guide rod and the buffer element.

[0013] Furthermore, the buffer element is a spring.

[0014] Furthermore, the other end of the connecting rod is fixedly connected to or integrally formed with a connecting slider, and the connecting slider has a through hole inside, which cooperates with the guide rod set on the linear guide rail.

[0015] The beneficial effects of this utility model are: 1. The electric shovel bucket device with buffer gate of this utility model, by setting a linear guide rail on the top of the bucket body, and the bucket gate is slidably connected to the linear guide rail through a connecting rod, converts part of the angular momentum generated during the opening process of the bucket gate into linear momentum, thereby reducing the reaction torque generated by the angular momentum.

[0016] 2. The electric shovel bucket device with buffer gate of this utility model, by setting two sets of connecting rods and linear guide rail devices, and setting two parallel guide rods in each linear guide rail, makes the force between the connecting rods and the linear guide rails stable during the opening and closing process of the bucket gate, thereby improving the stability of the bucket gate opening and closing and the service life of the connecting rods and linear guide rails.

[0017] 3. By installing detachable guide rods on the linear guide rail, the replacement of guide rods and buffer elements is facilitated. Elongated holes on the linear guide rail allow for easy observation of the wear level of the guide rods and buffer elements, enabling timely replacement. Attached Figure Description

Detailed Implementation

[0020] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-3 As shown, this utility model provides an electric shovel bucket device with a buffer gate, including a bucket body 1 and a gate 2. A first hinge seat 3 is fixedly provided on the top of the gate 2. The gate 2 is hinged to the first hinge seat 3 via a gate connecting rod 4. The gate connecting rod 4 is hinged to a connecting rod 5, and the other end of the connecting rod 5 is slidably frictionally connected to a linear guide rail 8. Specifically, two sets of combined connection structures of the gate connecting rod 4, the first hinge seat 3, the connecting rod 5, and the linear guide rail 8 are provided, symmetrically arranged on one side of the top of the gate 2 near the gate 2. More specifically, one end of the gate connecting rod 4 fixedly connected to the gate 2 is straight, and the other end is connected to an arc-shaped connecting part to facilitate a transition hinge to the first hinge seat 3. Specifically, the end of the connecting rod 5 near the gate 2 is hinged to a second hinge seat 6 provided on the gate connecting rod 4. More specifically, the connecting rod 5 is arc-shaped, and the second hinge seat 6 is fixedly connected to or integrally formed on the arc-shaped connecting part of the gate connecting rod 4 to facilitate the hinge connection between the connecting rod 5 and the gate connecting rod 4.

[0022] A buffer element is provided on the linear guide rail 8. The buffer element is located at both ends of the sliding stroke of the connecting rod 5 on the linear guide rail 8 during the opening and closing of the sluice gate 2. It is used to buffer the sliding process of the connecting rod 5 on the linear guide rail 8 during the opening and closing of the sluice gate 2. Specifically, the buffer element can be a spring 10 or a rubber element. Any element that can play a buffering role can be used. By setting the buffer element, the buffering of the opening and closing process of the sluice gate 2 is achieved.

[0023] This invention provides a linear guide rail 8 at the top of the bucket body 1, and the bucket gate 2 is slidably connected to the linear guide rail 8 via a connecting rod, so that part of the angular momentum generated during the opening of the bucket gate is converted into linear momentum, thereby reducing the reaction torque generated by the angular momentum.

[0024] Specifically, the linear guide rail 8 is detachably connected to guide rods 9 to facilitate replacement. More specifically, the linear guide rail 8 has two parallel guide rods 9. The other end of the connecting rod 5 is fixedly connected to or integrally formed with a connecting slider 7. The connecting slider 7 has a through hole inside, which mates with the guide rod 9 on the linear guide rail 8. More specifically, the connecting slider 7 has two through holes, which are respectively fitted onto the two parallel guide rods 9. By setting two parallel guide rods 9, the stability of the force between the connecting slider 7 and the guide rods 9 can be improved during the opening and closing of the sluice gate 2, avoiding damage caused by unilateral force and extending the service life of the connecting rod 5 and the guide rods 9. The contact area between the connecting slider 7 and the guide rods 9 also has sliding friction, which also serves as a buffer.

[0025] The linear guide rail 8 has a U-shaped housing with a flat bottom. The bottom of the U-shaped housing is fixedly connected to the top of the bucket body 1. Guide rods 9 are provided on both side walls of the U-shaped housing. The end of the U-shaped housing away from the bucket door 2 has an inlet and outlet for the guide rods 9. A guide rail end cap 11 is detachably connected to the outside of the inlet and outlet of the guide rods 9. An elongated hole is provided on the side wall of the linear guide rail 8, which corresponds to the position of the guide rods 9 and the buffer element. Specifically, the guide rods 9 are installed from the inlet and outlet of the U-shaped housing away from the bucket door 2. Springs are provided at both ends of the guide rods 9, and the connecting slider 7 of the connecting rod 5 passes through the middle. After installation, the end is sealed by the guide rail end cap 11. The guide rail end cap 11 can be detachably connected to the U-shaped housing by bolts 12, which facilitates the replacement of the connecting slider 7, guide rods 9, and buffer element. The elongated hole on the side wall of the linear guide rail 8 serves four main functions: first, as a limiting groove connecting the slider 7, guide rod 9, and buffer element; second, as a clearance groove connecting the slider 7 and guide rod 9 for sliding; third, as an operating hole, allowing for handling of any abnormalities such as jamming or foreign objects in the connecting slider 7, guide rod 9, and buffer element; and fourth, as a means of observing the condition of the connecting slider 7, guide rod 9, and buffer element, enabling timely replacement of severely worn parts.

[0026] The working process of this electric bucket device is as follows: During the material unloading process in the electric shovel bucket, when the bucket gate 2 opens to a certain angle, the connecting slider 7 of the connecting rod 5 moves to one end on the guide rod 9 and contacts the buffer element at one end. During this process, the friction between the connecting slider 7 and the guide rod 9, along with the buffer element, jointly buffer the bucket gate 2. After the material in the electric shovel bucket is unloaded, the bucket gate 2 enters the closing process. The connecting slider 7 of the connecting rod 5 moves to the other end on the guide rod 9 and contacts the buffer element at the other end, thus achieving the buffering effect on the bucket gate 2.

[0027] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any modifications, alterations, substitutions, and variations made by those skilled in the art to the above embodiments are within the scope of the present invention.
