Description

Technical Field

[0001] This utility model relates to the technical field of flat-bottomed silo carriage mechanism, and in particular to a flat-bottomed silo carriage mechanism. Background Technology

[0002] A flat-bottomed silo carriage mechanism is commonly used to solve problems such as poor flow, blockage, or uneven discharge of materials (e.g., powders and granules) in silos. This mechanism, through its movable carriage structure, assists in the smooth discharge of materials from the bottom of the silo, and is particularly suitable for flat-bottomed silos (i.e., silos with a flat bottom rather than a cone shape) to improve discharge efficiency and prevent material accumulation.

[0003] A flat-bottomed silo slide mechanism has a wide range of applications. Existing publication CN 206125929 U describes a flat-bottomed silo slide structure, including a silo and a slide disposed inside the silo. The silo has a discharge port at its bottom end, and a drive cylinder on one side of the silo to push the slide horizontally. The bottom of the silo has a first guide block and a second guide block, arranged along the horizontal sliding direction. The bottom of the slide has a first guide rail cooperating with the first guide block and a second guide rail cooperating with the second guide block. This provides a flat-bottomed silo slide structure for breaking up sludge arches and unloading, and preventing sludge bridging. In existing technical documents, when handling highly viscous or easily agglomerated materials, especially in large silos, a single-layer slide may not be sufficient to completely break up the arched structure formed by the material, leading to uneven material discharge and causing local accumulation or voids. Furthermore, in existing technical documents, the slide is subject to impact wear when breaking up material arches, which affects its service life over time. Therefore, a flat-bottomed silo slide mechanism is proposed. Utility Model Content

[0004] The main purpose of this utility model is to provide a flat-bottomed silo carriage mechanism, which solves the problem in existing technical documents that when handling highly viscous or easily agglomerated materials, especially in large-sized silos, a single-layer carriage may not be sufficient to completely break the arched structure formed by the material, resulting in uneven material discharge, causing local accumulation or voids. In existing technical documents, the carriage is subject to impact wear when breaking up the material arch, which affects the service life of the carriage after long-term use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A flat-bottomed silo carriage mechanism includes a mounting base plate. An electric push rod is fixedly connected to the top of the mounting base plate. A first transmission rod is fixedly connected to one output end of the electric push rod. A first toothed plate is fixedly connected to the outer side of the first transmission rod. A first gear is toothed on the outer side of the first toothed plate. A first connecting rod is fixedly sleeved inside the first gear. A mounting sleeve is movably sleeved on the lower outer side of the first connecting rod. The mounting base plate is fixedly connected to the lower side of the mounting sleeve. A first bevel gear is fixedly connected to the top of the first connecting rod. A second bevel gear is toothed on the outer side of the first bevel gear. A second connecting rod is fixedly connected to the outer side of the second bevel gear. A mounting bracket is movably sleeved on the outer side of the second connecting rod. The mounting base plate is fixedly connected to the lower side of the mounting bracket. A flat-bottomed silo body is fixedly connected to one side of the mounting base plate.

[0006] Furthermore, a third connecting rod is movably sleeved on the inner side of the mounting bracket, a third bevel gear is fixedly connected to the inner side of the third connecting rod, a second bevel gear is toothed on one side of the third bevel gear, a second gear is fixedly sleeved on the outer side of the third connecting rod, a second toothed plate is toothed on one side of the second gear, a second transmission rod is fixedly connected to one side of the second toothed plate, and one end of the second transmission rod is movably sleeved in the flat-bottomed hopper body.

[0007] Furthermore, one end of the first transmission rod is fixedly connected to a first connecting bracket, and one end of the second transmission rod is fixedly connected to a second connecting bracket. A carriage assembly is fixedly connected to the inner side of both the first and second connecting brackets. The two carriage assemblies have the same structure. The carriage assembly includes a carriage frame. One side of the carriage frame is fixedly connected to the first connecting bracket. Two support rods are fixedly connected at equal intervals inside the carriage frame. Several pusher plates are fixedly connected at equal intervals inside the first connecting bracket.

[0008] Furthermore, the flat-bottomed hopper is internally fixedly connected with four support blocks at equal intervals, and the four support blocks are arranged in pairs. Each of the four support blocks has a first limiting hole and a second limiting hole. The two first limiting holes on the same side form a group, and the two groups of first limiting holes are movably fitted with a second connecting bracket. The two second limiting holes on the same side form a group, and the two groups of second limiting holes are movably fitted with a second connecting bracket.

[0009] Furthermore, a first impact block abuts against one side of the upper part of the carriage frame, and two second impact blocks abut against the other side of the upper part of the carriage frame at equal intervals. Several shock-absorbing components are installed at equal intervals on the inner sides of the first impact block and the two second impact blocks. The shock-absorbing components include connecting blocks. The carriage frame is fixedly connected to the lower part of the connecting blocks. An installation groove is opened on the inner side of the first impact block. A spring is fixedly connected to the inner side of the connecting block. The inner side of the spring is fixedly connected to the inner wall of the installation groove.

[0010] Furthermore, a control panel is fixedly connected to the top of the mounting base plate, and the control panel is electrically connected to an electric push rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through the provision of a second transmission rod, enables two carriage assemblies to move in opposite directions, further enhancing the material dispersion and pushing effect, improving material discharge efficiency, and reducing material accumulation. When material discharge is required, an electric push rod is activated. The electric push rod drives one carriage assembly to move via the first transmission rod and the first connecting bracket. Simultaneously, the first transmission rod drives the first gear via the first toothed plate. The first gear drives the second gear via the first connecting rod, the first bevel gear, the second bevel gear, the third bevel gear, and the second connecting rod. The second gear drives the second transmission rod via the second toothed plate. The second transmission rod drives the other carriage assembly to move via the second connecting bracket. Thus, the two carriage assemblies move in opposite directions. When the carriage assemblies move, the carriage frame drives the pusher plate, the first impact block, and the second impact block to disperse the material and break up the material bridge. Through this arrangement, the two carriage assemblies can be driven to move in opposite directions, further enhancing the material dispersion and pushing effect, improving material discharge efficiency, and reducing material accumulation.

[0012] 2. The springs in this utility model can dampen and buffer the first and second impact blocks, reduce slide wear, and extend the service life of the equipment. When the first and second impact blocks hit the material, the impact force on the first and second impact blocks can be transmitted to the springs. The springs can dampen and buffer the first and second impact blocks. With this design, the first and second impact blocks can be damped and buffered, reduce slide wear, and extend the service life of the equipment.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-6As shown, a flat-bottomed hopper carriage mechanism includes a mounting base plate 1. An electric push rod 2 is fixedly connected to the top of the mounting base plate 1. A first transmission rod 3 is fixedly connected to one output end of the electric push rod 2. A first toothed plate 5 is fixedly connected to the outer side of the first transmission rod 3. A first gear 6 is toothed on the outer side of the first toothed plate 5. A first connecting rod is fixedly sleeved inside the first gear 6. A mounting sleeve 7 is movably sleeved on the lower outer side of the first connecting rod. The mounting base plate 1 is fixedly connected to the lower part of the mounting sleeve 7. A first bevel gear is fixedly connected to the top of the first connecting rod. 8. A second bevel gear 9 is toothed on the outer side of the first bevel gear 8. A second connecting rod is fixedly connected to the outer side of the second bevel gear 9. A mounting bracket 10 is movably sleeved on the outer side of the second connecting rod. A mounting base plate 1 is fixedly connected to the lower part of the mounting bracket 10. A flat-bottomed silo body is fixedly connected to one side of the mounting base plate 1. By adopting the above technical solution, one end of the first transmission rod 3 is inserted into the flat-bottomed silo body. A sealing ring is installed on the outer side of the flat-bottomed silo body to prevent the material inside the flat-bottomed silo body from leaking from the gap between the first transmission rod 3 and the flat-bottomed silo body. A limit baffle is installed on the inner side of the mounting sleeve 7, which can limit the first connecting rod to rotate only around the mounting sleeve 7 as the axis, and prevent displacement in other directions. A limit baffle is installed on the inner side of the mounting bracket 10, which can limit the second connecting rod to rotate only and prevent it from displacing in other directions. The bottom of the flat-bottomed hopper body has a discharge port, and a screw is installed below the discharge port to continuously discharge materials.

[0023] The inner side of the mounting bracket 10 is movably sleeved with a third connecting rod, and the inner side of the third connecting rod is fixedly connected with a third bevel gear 11. One side of the third bevel gear 11 is toothed into a second bevel gear 9. The outer side of the third connecting rod is fixedly sleeved with a second gear 12. One side of the second gear 12 is toothed into a second toothed plate 13. One side of the second toothed plate 13 is fixedly connected with a second transmission rod 24. One end of the second transmission rod 24 is movably sleeved into the flat bottom hopper body. By adopting the above technical solution, a protective cover is fixedly connected to the outer side of the mounting base plate 1, which can protect the movement of components such as the second toothed plate 13, the first toothed plate 5, the first gear 6, the second gear 12, and the second bevel gear 9. In addition, the movement range of the second toothed plate 13 and the first toothed plate 5 can be limited inside the protective cover, so that the second toothed plate 13 always maintains toothed engagement with the second gear 12, and the first gear 6 maintains toothed engagement with the first toothed plate 5. A limit baffle is installed on the inner side of the mounting bracket 10, which can limit the third connecting rod to rotate only and prevent it from displacing in other directions. A limit baffle is installed on the inner side of the flat-bottomed hopper body, which can limit the second transmission rod 24 to rotate only and prevent it from displacing in other directions. A sealing ring is installed on the outside of the flat-bottomed silo body to prevent material inside the silo body from leaking through the gap between the second transmission rod 24 and the flat-bottomed silo body.

[0024] One end of the first transmission rod 3 is fixedly connected to the first connecting bracket 4, and one end of the second transmission rod 24 is fixedly connected to the second connecting bracket 25. The inner sides of the first connecting bracket 4 and the second connecting bracket 25 are both fixedly connected to the carriage assembly. The two carriage assemblies have the same structure. The carriage assembly includes a carriage frame 14. One side of the carriage frame 14 is fixedly connected to the first connecting bracket 4. Two support rods 26 are fixedly connected at equal intervals inside the carriage frame 14. Several push plates 15 are fixedly connected at equal intervals inside the first connecting bracket 4. By adopting the above technical solution, the push plates 15 are simultaneously fixedly sleeved inside the passing support rods 26, which can play a role in strengthening the structural strength of the carriage frame 14. The carriage assembly connected to the first connecting bracket 4 and the second connecting bracket 25 has the same structure, which greatly simplifies the manufacturing and maintenance process. It is a modular design concept that greatly simplifies the manufacturing and maintenance process. The pusher plate 15 has a sloping side, which makes it easy to push materials.

[0025] The flat-bottomed hopper has four support blocks 16 fixedly connected at equal intervals inside, and the four support blocks 16 are arranged in pairs. Each of the four support blocks 16 has a first limiting hole 17 and a second limiting hole 18. The two first limiting holes 17 on the same side form a group, and the two groups of first limiting holes 17 are movably connected to the second connecting bracket 25. The two second limiting holes 18 on the same side form a group, and the two groups of second limiting holes 18 are movably connected to the second connecting bracket 25. By adopting the above technical solution, the support blocks 16 can play a limiting function. The support rod 26 can be limited through the first limiting holes 17 and the second limiting holes 18, thereby limiting the slide frame 14 to only move in a straight line.

[0026] A first impact block 19 abuts against one side of the upper part of the carriage frame 14, and two second impact blocks 20 abut against the other side of the upper part of the carriage frame 14 at equal intervals. Several shock-absorbing components are installed at equal intervals on the inner sides of the first impact block 19 and the two second impact blocks 20. The shock-absorbing components include a connecting block 22. The carriage frame 14 is fixedly connected to the lower part of the connecting block 22. An installation groove 21 is opened on the inner side of the first impact block 19. A spring 23 is fixedly connected to the inner side of the connecting block 22. The inner side of the spring 23 is fixedly connected to the inner wall of the installation groove 21. By adopting the above technical solution, an installation groove 21 is opened in both the first impact block 19 and the two second impact blocks 20 for installing the connecting block 22. The inner wall of the connecting block 22 is equipped with a buffer pad, which is connected to the spring 23 to enhance the buffering effect. A limit baffle is installed above the carriage frame 14 to limit the first impact block 19 and the second impact block 20 to abut against the carriage frame 14, limiting the first impact block 19 and the second impact block 20 to only move linearly along the support rod 26 on the carriage frame 14, and keeping the connecting block 22 installed in the mounting groove 21. The connecting block 22 can limit the movement range of the first impact block 19 and the second impact block 20 in the opposite direction, and the spring 23 can drive the first impact block 19 and the second impact block 20 to reset. Furthermore, sealing strips are installed at the bottom of both the first impact block 19 and the second impact block 20 to prevent materials from seeping into the mounting groove 21; The first impact block 19 and the second impact block 20 are both made of wear-resistant buffer material, which can impact materials and prevent them from forming arches.

[0027] A control panel is fixedly connected to the top of the mounting base plate 1. The control panel is electrically connected to the electric push rod 2. By adopting the above technical solution, the control panel can control the movement of the electric push rod 2.

[0028] It should be noted that when an external power supply is connected via the control panel, the electric push rod 2 is activated when material discharge is required. The electric push rod 2 drives a carriage assembly to move through the first transmission rod 3 and the first connecting bracket 4. At the same time, the first transmission rod 3 drives the first gear 6 through the first toothed plate 5. The first gear 6 drives the second gear 12 through the first connecting rod, the first bevel gear 8, the second bevel gear 9, the third bevel gear 11, and the second connecting rod. The second gear 12 drives the second transmission rod 24 through the second toothed plate 13. The second transmission rod 24 drives the other carriage assembly to move through the second connecting bracket 25. Thus, the two carriage assemblies move in opposite directions. When the carriage assemblies move, the carriage frame 14 drives the pusher plate 15, the first impact block 19, and the second impact block 20 to break up the material and destroy the material bridge.

[0029] When the carriage assembly moves and scatters the material, the impact force on the first impact block 19 and the second impact block 20 can be transmitted to the spring 23 when they impact the material. The spring 23 can then dampen and buffer the first impact block 19 and the second impact block 20.

[0030] The main purpose of this utility model is to provide a flat-bottomed silo carriage mechanism, which solves the problem in existing technical documents that when handling highly viscous or easily agglomerated materials, especially in large-sized silos, a single-layer carriage may not be sufficient to completely break the arched structure formed by the material, resulting in uneven material discharge, causing local accumulation or voids. In existing technical documents, the carriage is subject to impact wear when breaking up the material arch, which affects the service life of the carriage after long-term use. This is more practical.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
