Description

Technical Field

[0001] This utility model relates to the field of self-propelled funnel technology, specifically a four-wheel drive, four-rotation self-propelled funnel. Background Technology

[0002] Mobile hoppers at wharves are core transfer equipment in port bulk cargo logistics systems. They are widely used in the loading, unloading, and transfer of bulk materials such as coal, ore, grain, and sand. They are key hubs connecting front-end unloading equipment (such as grab unloaders and continuous unloaders) and back-end transportation vehicles (such as belt conveyors, trucks, and silos). The equipment is designed with "mobility" as its core highlight. It is usually moved by tire-mounted or rail-mounted methods to adapt to the transfer needs of different berths and material storage areas.

[0003] Existing mobile dock hoppers are equipped with wheels at the bottom of the main frame, but they often lack a walking drive mechanism and a turning drive mechanism. This means that the mobile dock hoppers can only move on a predetermined track or be moved by a large forklift. They cannot walk or turn on their own, making them unsuitable for relocation operations in narrow spaces and thus impractical. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a four-wheel drive, four-rotation self-propelled funnel, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a four-wheel drive, four-rotation self-propelled funnel, comprising a main frame and a funnel body fixedly installed in the middle of the inner side of the main frame. An upper support frame and a lower support beam are sequentially arranged from top to bottom on the inner side of the main frame. A ladder is welded and installed on the outer side of the main frame. An electrical control box is fixedly installed on the outer side of the lower support beam. Walking wheel assemblies are installed diagonally at the four corners of the lower part of the main frame. A walking drive assembly is arranged inside the walking wheel assembly, and a rotation drive assembly is arranged on the side of the top of the walking wheel assembly. A side platform is also provided on the outer side of the main frame. A rotatable funnel body is installed at the opening at the lower part of the funnel body. The device includes a gate assembly, a hydraulic drive assembly between the gate assembly and the funnel body, a hydraulic support leg fixedly installed on the side of the lower support beam away from the upper support frame, a main ear seat fixedly installed in the middle of the top of the main frame, secondary upper ear seats fixedly installed on both sides of the top of the main frame, secondary middle ear seats fixedly installed on both sides of the top of the upper support frame, an upper support rod one between the main ear seat and the secondary middle ear seat, an upper support rod two between the secondary upper ear seat and the secondary middle ear seat, secondary lower ear seats fixedly installed on both sides of the lower support beam facing the upper support frame, and a lower support rod between the secondary lower ear seat and the secondary middle ear seat.

[0006] Preferably, there are four identical walking wheel assemblies, walking drive assemblies, and slewing drive assemblies, which are symmetrically distributed at the four corners of the bottom of the main frame.

[0007] Through the above technical solutions, the independent walking drive component can ensure that each wheel receives sufficient power, improving the equipment's ability to move through complex sites. The independent slewing drive component can flexibly adjust the steering of each wheel, enabling the equipment to achieve multiple movement modes such as turning in place and walking diagonally, greatly improving the mobility and spatial adaptability during operation, and is especially suitable for relocation operations in narrow sites.

[0008] Preferably, the upper support frame and the lower support beam are provided with four identical beams, and the four upper support frames and lower support beams are symmetrically distributed about the central axis of the main frame.

[0009] Through the above technical solution, four symmetrically distributed upper support frames and lower support beams constitute the core load-bearing frame of the main frame, which evenly transfers the weight of the funnel body and the load of the internal materials to various parts of the main frame, effectively dispersing stress concentration and improving the load-bearing strength and stability of the overall structure.

[0010] Preferably, the main ear seat, the secondary upper ear seat, the secondary middle ear seat, the first upper support rod, the second upper support rod, the secondary lower ear seat, and the lower support rod are provided in four identical sets. The number of the secondary upper ear seat, the secondary middle ear seat, the first upper support rod, the second upper support rod, the secondary lower ear seat, and the lower support rod in each set is twice that of the main ear seat, and they are symmetrically distributed about the vertical axis of the main ear seat.

[0011] Through the above technical solution, four sets of symmetrically distributed support components form a multi-node, all-round internal support system. The upper support rod one, upper support rod two and lower support rod cooperate with each other to tightly connect the top of the main frame with the upper support frame and the lower support beam into a whole, further enhancing the rigidity and deformation resistance of the structure.

[0012] Preferably, the number of hydraulic support legs is twice that of the lower support beams, and the lower support beams are symmetrically distributed at the bottom of the hydraulic support legs.

[0013] Through the above technical solution, a sufficient number of hydraulic support legs cooperate with symmetrically distributed lower support beams. When the equipment is unloading, the hydraulic support legs can extend smoothly and support the ground, forming a stable support surface. This directly transfers the overall weight of the equipment and the material load to the ground, avoiding excessive pressure on the walking wheel assembly and protecting the walking system from damage.

[0014] Preferably, the number of hydraulic drive components is twice that of the gate components, the hydraulic drive components are symmetrically distributed on the sides of the gate components, and the vertical axis of the gate components and the funnel body are on the same vertical line.

[0015] Through the above technical solution, the hydraulic drive component can drive the opening and closing of the bucket door component, which facilitates loading materials onto the truck.

[0016] Compared with the prior art, this utility model provides a four-wheel drive, four-rotation self-propelled funnel, which has the following beneficial effects: 1. This four-wheel drive, four-turn self-propelled funnel is equipped with four independent walking drive components and turning drive components at the four corners of the bottom of the main frame. This ensures that each wheel receives sufficient power while allowing for flexible adjustment of the steering of each wheel. This enables the equipment to achieve multiple movement modes such as straight-line walking, diagonal movement, and turning in place, greatly improving its ability to pass through complex sites. It is especially suitable for relocation operations in narrow spaces and has high practicality. 2. This four-wheel drive, four-rotation self-propelled funnel has four symmetrically distributed upper support frames and lower support beams forming the core load-bearing frame. Combined with four sets of multi-node internal support structures, it can evenly transfer and disperse the load of the funnel body and materials, significantly enhancing the overall structure's load-bearing strength, rigidity, and resistance to deformation.

[0019] 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.

[0020] Example 1: As Figure 1-5 As shown, this utility model provides a four-wheel drive, four-rotation self-propelled funnel, including a main frame 1 and a funnel body 2 fixedly installed in the middle of the inner side of the main frame 1. An upper support frame 9 and a lower support beam 3 are arranged sequentially from top to bottom on the inner side of the main frame 1. A ladder 6 is welded and installed on the outer side of the main frame 1. An electrical control box 4 is fixedly installed on the outer side of the lower support beam 3. Four diagonally opposite corners of the lower part of the main frame 1 are mounted with walking wheel assemblies 10. A walking drive assembly 11 is arranged inside the walking wheel assembly 10, and a rotation drive assembly 12 is arranged on the side of the top of the walking wheel assembly 10. A side platform 13 is also provided on the outer side of the main frame 1. A funnel gate assembly 7 is rotatably installed at the opening at the lower part of the funnel body 2. A hydraulic drive assembly 8 is provided between the door assembly 7 and the funnel body 2. A hydraulic support leg 5 is fixedly installed on the side of the lower support beam 3 away from the upper support frame 9. A main ear seat 14 is fixedly installed in the middle of the top of the main frame 1. A secondary upper ear seat 15 is fixedly installed on both sides of the top of the main frame 1. A secondary middle ear seat 16 is fixedly installed on both sides of the top of the upper support frame 9. An upper support rod 17 is provided between the main ear seat 14 and the secondary middle ear seat 16. An upper support rod 28 is provided between the secondary upper ear seat 15 and the secondary middle ear seat 16. A secondary lower ear seat 19 is fixedly installed on both sides of the side of the lower support beam 3 facing the upper support frame 9. A lower support rod 20 is provided between the secondary lower ear seat 19 and the secondary middle ear seat 16.

[0021] Example 2: like Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0022] Specifically, four identical walking wheel assemblies 10, walking drive assemblies 11, and slewing drive assemblies 12 are provided, symmetrically distributed at the four corners of the bottom of the main frame 1. The advantages are that the independent walking drive assembly 11 ensures sufficient power to each wheel, improving the equipment's mobility in complex terrain, while the independent slewing drive assembly 12 allows for flexible adjustment of the steering of each wheel, enabling the equipment to achieve various movement modes such as turning in place and diagonal movement, significantly improving maneuverability and spatial adaptability during operation, especially suitable for relocation operations in narrow spaces.

[0023] Example 3: like Figure 2-5As shown, this is an improvement on the previous embodiment.

[0024] Specifically, both the upper support frame 9 and the lower support beam 3 are provided with four identical beams, which are symmetrically distributed about the central axis of the main frame 1. The advantage is that the four symmetrically distributed upper support frames 9 and lower support beams 3 constitute the core load-bearing frame of the main frame 1, evenly distributing the weight of the funnel body 2 and the load of the internal materials to various parts of the main frame 1, effectively dispersing stress concentration and improving the overall structural load-bearing strength and stability.

[0025] Specifically, the main ear seat 14, the secondary upper ear seat 15, the secondary middle ear seat 16, the upper support rod 17, the upper support rod 28, the secondary lower ear seat 19, and the lower support rod 20 are arranged in four identical sets. Each set of secondary upper ear seat 15, secondary middle ear seat 16, upper support rod 17, upper support rod 28, secondary lower ear seat 19, and lower support rod 20 has twice the number of main ear seat 14 components, and they are symmetrically distributed about the vertical axis of the main ear seat 14. The advantage is that the four symmetrically distributed support components form a multi-node, all-around internal support system. The upper support rod 17, upper support rod 28, and lower support rod 20 cooperate with each other to tightly connect the top of the main frame 1 with the upper support frame 9 and the lower support beam 3 into a whole, further enhancing the rigidity and deformation resistance of the structure.

[0026] Specifically, the number of hydraulic support legs 5 is twice that of the lower support beams 3, which are symmetrically distributed below the hydraulic support legs 5. The advantage is that the sufficient number of hydraulic support legs 5, in conjunction with the symmetrically distributed lower support beams 3, allows the hydraulic support legs 5 to extend smoothly and support the ground during unloading operations, forming a stable support surface. This directly transfers the overall weight of the equipment and the material load to the ground, preventing excessive pressure on the traveling wheel assembly 10 and protecting the traveling system from damage.

[0027] Specifically, the number of hydraulic drive components 8 is twice that of the gate assembly 7. The hydraulic drive components 8 are symmetrically distributed on the sides of the gate assembly 7, and the vertical axis of the gate assembly 7 and the funnel body 2 are on the same vertical line. The advantage is that the hydraulic drive components 8 can drive the gate assembly 7 to open and close, which facilitates the loading of materials onto the truck.

[0028] Working principle: In operation, the equipment is first started via the electrical control box 4. The walking drive components 11 at the four corners of the bottom of the main frame 1 provide power to the corresponding walking wheel components 10. In conjunction with the rotary drive component 12, the steering of each wheel is flexibly adjusted, enabling the equipment to move in a straight line, at an angle, or in place within the work area, accurately reaching the designated unloading position. Once the equipment reaches the target position, the electrical control box 4 controls the hydraulic support legs 5 on the lower support beam 3 to extend and firmly support the equipment on the ground, preventing damage to the walking wheel components 10 due to pressure. The main ear seat 14, the secondary upper ear seat 15 and other ear seat structures, together with the upper support rod 17, the upper support rod 28 and the lower support rod 20, form an internal support system that can effectively bear the weight of the material and distribute the stress, ensuring the structural stability of the main frame 1, the upper support frame 9 and the lower support beam 3. When unloading is required for equipment such as trucks, the hydraulic drive component 8 at the bottom of the funnel body 2 is controlled by the electrical control box 4, which drives the gate component 7 to rotate around the connection point with the funnel body 2 to open and close, and the material falls down along the opening of the funnel body 2 to complete the unloading operation.

[0029] 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.
