Description

Technical Field

[0001] This utility model discloses a polygonal arc-shaped double roller extrusion snow loading device, which belongs to the field of snow removal equipment. Background Technology

[0002] Snow removal in winter is crucial for ensuring smooth and safe road traffic. After the roads are cleared, the accumulated snow on both sides needs to be transported to designated locations in the suburbs for disposal. Currently, there are three main methods for snow removal:

[0003] Manual snow loading: This method is extremely inefficient and requires a lot of manpower and time. It not only obstructs traffic but also keeps workers' labor intensity high. When working on roads with heavy traffic, workers face greater safety risks.

[0004] Snow loading by loader: Compared to manual snow loading, loaders are more efficient. However, loaders have a large operating radius, severely disrupting traffic. Furthermore, the snow loaded into transport vehicles is mostly loose, with low density, resulting in a small load per vehicle per trip, low transportation efficiency, and significantly increased transportation costs. Snowplow loading: Snowplows load snow quickly, filling a truck in minutes. However, the snow they load is loose, like cotton, resulting in a low effective load per vehicle per trip and high transportation costs. In actual snow removal operations, transportation costs far exceed the cost of the snow removal operation itself. Utility Model Content

[0005] The purpose of this invention is to solve the problems of high cost and low efficiency of existing snow loading methods, and to propose a polygonal arc-shaped double roller extrusion snow loading device.

[0006] The problem to be solved by this utility model is achieved by the following technical solution:

[0007] A multi-sided arc-shaped double-roller extrusion snow-filling device includes a hopper assembly. The hopper assembly is rotatably equipped with two U-shaped swing linkage assemblies. Arc-shaped rollers are rotatably mounted at both ends of the two U-shaped swing linkage assemblies. The two U-shaped swing linkage assemblies are connected together by a tension spring. A feed inlet is provided in the middle of the hopper assembly. The two arc-shaped rollers are located below the feed inlet and are driven to rotate by a drive assembly provided on the hopper assembly to form an extrusion operation.

[0008] Preferably, the hopper assembly includes: a hopper frame, on which swing brackets are symmetrically arranged, two U-shaped swing linkage assemblies are rotatably mounted on the swing brackets, a feed inlet is provided in the middle of the hopper frame, and a drive bracket is provided on one side of the hopper frame, the drive bracket being used to support the power source in the drive assembly.

[0009] Preferably, the power source includes a drive gear set mounted on the drive bracket, and the input end of the drive gear set is connected to the main shaft of the motor.

[0010] Preferably, the U-shaped swing linkage assembly includes a rotating sleeve fixed on the swing bracket, with both ends of the rotating sleeve rotatably connected to one end of the swing linkage, and two adjacent swing linkages on one side of the hopper frame connected by a tension spring. One end of the swing bracket is connected to a limiting end cap, which is used to limit either of the two swing linkages.

[0011] Preferably, the arc-shaped roller includes three arc-shaped rollers connected end to end in sequence, with a rotating shaft connected to each end of the rollers. Multiple extrusion strips are provided at intervals along the axial direction on the outer side of the arc-shaped rollers. The two rotating shafts are rotatably connected to the other ends of the two swing brackets. The rotating shafts pass through the swing connecting rod and are connected to the first end cover.

[0012] Preferably, the drive assembly further includes two rotating shafts, which are rotatably mounted in two rotating sleeves via symmetrically arranged bearings. The two bearings are enclosed in the rotating sleeves by two second end caps. A first driven pulley and a second driven pulley are respectively provided on the two rotating shafts near the drive gear set. Two driving pulleys are respectively provided on the two output ends of the drive gear set. The two driving pulleys are connected to the two second driven pulleys via a first synchronous belt. A third driven pulley is respectively provided on the two rotating shafts near the drive gear set. The two third driven pulleys are connected to the first driven pulley via a second synchronous belt.

[0013] This invention provides a multi-arc double-roller snow-loading device. Through the combination of a hopper assembly and a U-shaped swing linkage assembly, the device exhibits extremely high adaptability to material feeding. Regardless of the flow rate or angle at which snow enters the inlet, the U-shaped swing linkage assembly will swing flexibly, ensuring that the arc-shaped rollers respond promptly and entrain the snow into the compression zone. Compared to traditional snow-loading equipment, it eliminates the need for frequent position adjustments, quickly collecting surrounding snow and significantly reducing preparation time before loading. Simultaneously, the powerful extrusion force generated by the opposing rotation of the double-arc rollers quickly compacts loose snow, increasing the weight of snow loaded per vehicle and effectively improving overall snow transport efficiency and reducing costs.

Detailed Implementation

[0020] The following is based on the appendix Figure 1-5 Further explanation of this utility model:

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1As shown, the first embodiment of this utility model provides a polygonal arc-shaped double roller extrusion snow-filling device based on the prior art, including a hopper assembly 200. The hopper assembly 200 is rotatably equipped with two U-shaped swing linkage assemblies 400. Arc-shaped rollers 300 are rotatably mounted at both ends of the two U-shaped swing linkage assemblies 400. The two U-shaped swing linkage assemblies 400 are connected together by a tension spring 500. A feed inlet is provided in the middle of the hopper assembly 200. The two arc-shaped rollers 300 are located below the feed inlet and are driven to rotate by a drive assembly 100 provided on the hopper assembly 200 to form an extrusion operation.

[0025] Snow enters the device through the inlet in the middle of the hopper assembly 200. Two U-shaped swing linkage assemblies 400, under the elastic action of tension springs 500, maintain a constant and sensitive response to the snow inflow. Regardless of the angle or flow rate of the snow, the U-shaped swing linkage assemblies 400 can swing flexibly around the rotational connection point of the hopper assembly 200. During this process, the arc-shaped rollers 300 installed at both ends of the U-shaped swing linkage assemblies 400 quickly align with the snow, guiding it into the extrusion zone, greatly reducing the time for pre-loading positioning and adjustment, and efficiently completing snow collection. The drive assembly 100, installed on the hopper assembly 200, provides stable power for the entire extrusion process. After startup, the drive assembly 100 drives the two arc-shaped rollers 300 to rotate in opposite directions, generating strong extrusion force. Thanks to the polygonal arc surface design of the arc-shaped rollers 300, the snow is subjected to uniform force during extrusion. Meanwhile, the tension spring 500 maintains a tight connection between the two U-shaped swing linkage assemblies 400, ensuring that the arc-shaped rollers 300 fit tightly, thus applying all-round, multi-layer compression to the snow. The density of the snow compacted by this device is significantly increased, resulting in a substantial increase in the weight of snow transported by a single vehicle. This reduces transportation costs while effectively preventing snow from spilling during transport.

[0026] All rotating components of the device, such as the connection between the arc-shaped roller 300 and the U-shaped swing linkage assembly 400, utilize high-precision bearings, greatly reducing wear during mechanical operation and minimizing the possibility of malfunctions. The drive assembly 100 is directly mounted on the hopper assembly 200, shortening the power transmission path, improving energy transmission efficiency, and reducing energy consumption. The device adopts a modular design, with each component relatively independent. If a component, such as the tension spring 500 or the arc-shaped roller 300, malfunctions, maintenance personnel can quickly locate and replace it without large-scale equipment disassembly, significantly reducing maintenance difficulty and ensuring the continuity and stability of snow removal operations. Operators only need to place the device near the snowdrift, and snow will naturally flow into the device through the inlet. During snow loading, the automatic adjustment mechanism of the U-shaped swing linkage assembly 400 and the arc-shaped roller 300 greatly reduces manual intervention and labor intensity. Furthermore, the device occupies little space during operation and has minimal impact on traffic, allowing snow removal operations to be carried out without interrupting traffic, significantly improving the safety and practicality of snow removal work.

[0027] like Figure 2 As shown, the hopper assembly 200 includes: a hopper frame 201, on which swing brackets 202 are symmetrically arranged; two U-shaped swing linkage assemblies 400 are rotatably mounted on the swing brackets 202 at their midpoints; a feed inlet is provided in the middle of the hopper frame 201; and a drive bracket 203 is provided on one side of the hopper frame 201. The drive bracket 203 supports the power source in the drive assembly 100. The power source includes a drive gear set 102 mounted on the drive bracket 203, and the input end of the drive gear set 102 is connected to the main shaft of the motor 101.

[0028] The hopper assembly 200, as a key component of the polygonal arc-shaped double-roller snow extrusion device, provides a reliable carrier for the collection and transfer of snow. The hopper frame 201 is the main supporting structure of the entire hopper assembly 200, with symmetrical swing brackets 202 mounted on its top. The two U-shaped swing linkage assemblies 400 are mounted on the swing brackets 202 via specially designed rotating connecting components in the middle. This design gives the U-shaped swing linkage assemblies 400 great flexibility, allowing them to adaptively adjust according to the snow's entry angle and flow rate. A spacious inlet is provided in the middle of the hopper frame 201 to ensure that snow can smoothly enter the device. Furthermore, a drive bracket 203 is located on one side of the hopper frame 201. It not only provides stable support for the power source in the drive assembly 100 but also optimizes the overall layout of the device and shortens the power transmission path.

[0029] like Figure 3 and Figure 5As shown, the U-shaped swing linkage assembly 400 includes a rotating sleeve 402 fixed on the swing bracket 202. Both ends of the rotating sleeve 402 are rotatably connected to one end of the swing linkage 401. Two adjacent swing linkages 401 on one side of the hopper frame 201 are connected by a tension spring 500. One end of the swing bracket 202 is connected to a limiting end cap 403, which is used to limit either of the two swing linkages 401. The arc-shaped roller 300 includes three arc-shaped rollers connected end-to-end in sequence. A rotating shaft 303 is connected to both ends of each roller. Multiple extrusion strips 301 are spaced along the axial direction on the outer side of the arc-shaped surface. Two rotating shafts 303 are rotatably connected to the other ends of the two swing brackets 202. The rotating shafts 303 pass through the swing linkages 401 and are connected to the first end cap 302.

[0030] The U-shaped swing linkage assembly 400 is flexibly connected to the swing bracket 202 via a rotating sleeve 402 fixed to the swing bracket 202. Both ends of the rotating sleeve 402 are rotatably connected to one end of the swing linkage 401, giving the swing linkage 401 multi-dimensional swing freedom. Two adjacent swing linkages 401 on one side of the hopper frame 201 are connected by a tension spring 500. The continuous tension provided by the tension spring 500 keeps the swing linkage 401 responsive to snow. One end of the swing bracket 202 is connected to a limiting end cap 403, which effectively limits the excessive swing of the swing linkage 401, preventing abnormal equipment operation due to excessive swing amplitude and ensuring stable and reliable snow collection.

[0031] The arc-shaped roller 300 consists of three rollers with arc-shaped surfaces connected end to end. Its unique polygonal arc design significantly increases the contact area with the snow, ensuring uniform force distribution during extrusion. Rotating shafts 303 are connected to both ends of the rollers, providing support for the rotation of the arc-shaped roller 300. Multiple extrusion strips 301 are spaced axially along the outer side of the arc-shaped surfaces, further enhancing the extrusion effect on the snow and increasing its compaction density. Two rotating shafts 303 are rotatably connected to the other ends of two swing supports 202, and the rotating shafts 303 pass through the swing linkage 401 and connect to the first end cover 302. This ensures the stability of the arc-shaped roller 300's rotation and cleverly connects the arc-shaped roller 300 to the U-shaped swing linkage assembly 400, forming a highly efficient and collaborative working module.

[0032] In this embodiment, the drive assembly 100 further includes two rotating shafts 106. The two rotating shafts 106 are rotatably mounted in two rotating sleeves 402 via symmetrically arranged bearings 105. The two bearings 105 are enclosed in the rotating sleeves 402 by two second end caps 104. A first driven pulley 107 and a second driven pulley 108 are respectively provided at one end of the two rotating shafts 106 near the drive gear set 102. Two driving pulleys 103 are respectively provided on the two output ends of the drive gear set 102. The two driving pulleys 103 and the two second driven pulleys 108 are connected together by a first synchronous belt 113. A third driven pulley 111 is respectively provided at one end of the two rotating shafts 303 near the drive gear set 102. The two third driven pulleys 111 and the first driven pulleys 107 are connected together by a second synchronous belt 112.

[0033] The drive assembly 100 serves as the power core of the device. After the motor 101 starts, it transmits power to the drive gear set 102. The drive gear set 102 matches the speed and torque output by the motor 101, and then transmits the power in an orderly manner to the arc-shaped roller 300 through a combination of pulleys and synchronous belts. The drive assembly 100 includes two rotating shafts 106, which are rotatably mounted in two rotating sleeves 402 via symmetrically arranged bearings 105. The two bearings 105 are sealed in the rotating sleeves 402 by two second end caps 104 to ensure the stability and sealing of the rotation of the rotating shafts 106. A first driven pulley 107 and a second driven pulley 108 are respectively provided on one end of the two rotating shafts 106 near the drive gear set 102. Two driving pulleys 103 are respectively provided on the two output ends of the drive gear set 102. The two driving pulleys 103 and the two second driven pulleys 108 are connected by a first synchronous belt 111 to realize the initial transmission of power. Meanwhile, two shafts 303 are respectively equipped with third driven pulleys 111 near the end of the drive gear set 102. The two third driven pulleys 111 are connected to the first driven pulley 107 through a second synchronous belt 112, further transmitting power to the arc-shaped roller 300, driving it to rotate. In this embodiment, all components of the entire device work closely together to achieve efficient snow loading, high compaction density, and stable and reliable operation, greatly improving the overall efficiency of snow removal operations.

It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
