Description

Technical Field

[0001] The present invention relates to the technical field of snow removal machinery and equipment, and in particular to a snow throwing device with an adjustable throwing barrel angle and an adjustment method. Background Art

[0002] The snow throwing device can be installed on a snowplow. When the snowplow is in operation, it can simultaneously shovel and throw snow to clear the snow on the road. The snow throwing barrel of the snow throwing device is mainly composed of a lower throwing barrel and an upper throwing barrel. The lower throwing barrel is directly connected to the blade chamber. Using the lower throwing barrel alone can achieve long-distance throwing, but the snow is scattered, which is suitable for snow removal operations in open areas. The upper throwing barrel is tilted when not in operation and needs to be docked with the lower throwing barrel when in operation. That is, the upper and lower throwing barrels work in conjunction, which can extend the movement path of snow in the snow throwing device, allowing the lower throwing barrel to divert the flow of snow to make the snow more dense, which is beneficial for resisting headwind throwing. It is often used in headwind working environments in open areas, airports that require loading trucks to transport the thrown snow, and urban road construction sites.

[0003] After the upper and lower throwing cannons are docked, they are mostly oriented vertically upward, and the snow outlet is at a high altitude. On windy roads, throwing against the wind may cause the snow thrown into the air to be blown onto the road surface by the headwind, affecting driving safety. Furthermore, the upper and lower throwing cannons can only dock well with the upper throwing cannon when they are vertically upward. If the tilt angle of the upper throwing cannon is directly adjusted by swinging, when the vertical tilt angle of the upper throwing cannon is too large, the matching gap between the upper and lower throwing cannons will be too large or the matching surfaces will be misaligned, resulting in snow leakage at the docking interface of the upper and lower throwing cannons, which will limit the swing angle of the upper and lower throwing cannons when they are working in conjunction.

[0038] Optionally, when only the lower throwing tube mechanism is enabled for operation, the swing mechanism drives the upper throwing tube mechanism to swing around the hinge point between the two to a horizontal state.

[0039] (3) Beneficial effects

[0040] The beneficial effects of the present invention are:

[0041] The lower throwing tube mechanism is rotatably connected to the swing mechanism, and both can rotate on their own without interfering with each other's rotation. The rotation axes of the lower throwing tube mechanism and the swing mechanism coincide with each other, so the equipment occupies less space and has higher transmission efficiency.

[0042] The upper throwing tube mechanism is hinged to the swing mechanism, and the swing mechanism can drive the upper throwing tube mechanism to swing around the hinge point between the two, thereby achieving docking or undocking of the upper throwing tube mechanism and the lower throwing tube mechanism. Compared with the traditional oil cylinder drive method, the hinged or rotating connection method reduces the required movement path for the lower throwing tube mechanism and improves the transmission efficiency. By driving the upper throwing tube mechanism to swing around the hinge point between the two through the swing mechanism, interference between the upper throwing tube mechanism and the lower throwing tube mechanism during the docking process can be effectively avoided; and the swing mechanism can rotate on its own, thereby achieving high-precision docking of the upper throwing tube mechanism and the lower throwing tube mechanism, improving the swing angle and docking interface accuracy when the upper and lower throwing tube mechanisms are working in conjunction, so that the snow throwing device will not leak snow when the upper and lower throwing tube mechanisms swing together.

[0043] The snow thrower utilizes a swing mechanism for auxiliary adjustment, enabling the swing angles of the upper and lower throwing cylinders to be adjusted, thereby adjusting the height of the snow outlet. The upper and lower throwing cylinders can be tilted at any angle to achieve coordinated operation after docking. Compared to existing snow throwers, this significantly lowers the height of the upper throwing cylinder's snow outlet, reducing the amount of time snow remains in the air, making it less susceptible to headwinds. This effectively reduces or prevents headwinds from blowing snow thrown from the snow outlet back onto the road, enhancing the snow thrower's cleaning effectiveness and improving driving safety.

[0057] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0058] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0059] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this disclosure, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0060] In the present invention, unless otherwise specified or limited, the terms "connect," "fix," etc. should be understood in a broad sense. For example, "fix" can mean fixed connection, detachable connection, or integration; "connection" can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0061] See also Figure 1The present invention provides a snow throwing device with an adjustable throwing barrel angle. The snow throwing device includes an upper throwing barrel mechanism 3, a lower throwing barrel mechanism 1, and a swinging mechanism 2. The lower throwing barrel mechanism 1 is rotatably connected to the swinging mechanism 2. Both the lower throwing barrel mechanism 1 and the swinging mechanism 2 are capable of self-rotation, and their rotation axes coincide. The upper throwing barrel mechanism 3 is hinged to the swinging mechanism 2, and the swinging mechanism 2 can drive the upper throwing barrel mechanism 3 to swing around the hinge point between the two. The snow throwing device includes a first operating state and a second operating state. The first operating state is a state in which the lower throwing barrel mechanism 1 operates alone. The snow discharge path of the lower throwing barrel mechanism 1 is shorter, the thrown snow falls to the ground faster, and the snow removal efficiency is higher. However, the snow is loose and easily blown away by headwinds. The second operating state is the state in which the upper throwing tube mechanism 3 and the lower throwing tube mechanism 1 work in conjunction. The upper throwing tube mechanism 3 extends the snow discharge path of the snow throwing device, and the snow is further compressed in the upper throwing tube mechanism 3, making the structure more stable. In theory, it is not easily blown away by the headwind after being thrown. However, because the upper throwing tube mechanism 3 can only dock with the lower throwing tube mechanism 1 in a vertically upward state, even if the upper throwing tube mechanism 3 can swing, the swing angle is limited, resulting in the upper throwing tube mechanism 3 having a snow outlet height that is too high. The snow takes a long time to fall to the ground after being thrown, and the time it is blown by the headwind is prolonged. The snow is still at risk of being blown away by the headwind after being thrown. Based on this, the snow throwing device, while integrating the first and second operating states, also improves the second operating state, so that the docking position of the upper throwing tube mechanism 3 and the lower throwing tube mechanism 1 can be adjusted, and the height of the snow outlet of the upper throwing tube mechanism 3 can be adjusted, thereby lowering the height of the snow outlet of the upper throwing tube mechanism 3, making the thrown snow structure stable and the landing time short, thereby improving the operating efficiency of the second operating state.

[0062] The lower throwing tube mechanism 1 is rotatably connected to the swing mechanism 2, and both can rotate on their own without interfering with each other. The rotation axes of the lower throwing tube mechanism 1 and the swing mechanism 2 coincide with each other, so the device occupies less space and has higher transmission efficiency.

[0063] The upper throwing tube mechanism 3 is hinged to the swing mechanism 2, and the swing mechanism 2 can drive the upper throwing tube mechanism 3 to swing around the hinge point between the two, thereby achieving docking or undocking of the upper throwing tube mechanism 3 and the lower throwing tube mechanism 1. Compared with the traditional oil cylinder drive method, the hinged, that is, the rotational connection method reduces the required movement path for the lower throwing tube mechanism 1 and improves the transmission efficiency. By driving the upper throwing tube mechanism 3 to swing around the hinge point between the two through the swing mechanism 2, interference between the upper throwing tube mechanism 3 and the lower throwing tube mechanism 1 during the docking process can be effectively avoided; and the swing mechanism 2 can rotate on its own, thereby achieving high-precision docking of the upper throwing tube mechanism 3 and the lower throwing tube mechanism 1, improving the swing angle and docking interface accuracy when the upper and lower throwing tube mechanisms are working in conjunction, so that the snow throwing device will not leak snow when the upper and lower throwing tube mechanisms swing together.

[0064] The snow throwing device uses a swing mechanism 2 for auxiliary adjustment, achieving adjustment of the swing angle of the upper and lower throwing cylinder mechanisms, and thus the height of the snow outlet. The upper and lower throwing cylinders can be tilted at any angle to achieve coordinated operation after docking. Compared with existing snow throwing devices, the height of the snow outlet of the upper throwing cylinder mechanism 3 can be greatly reduced, reducing the time snow stays in the air, making it less likely to be blown away by headwinds. This effectively reduces or prevents the situation where headwinds blow snow thrown from the snow outlet back onto the road, enhancing the snow throwing device's cleaning effect and improving driving safety.

[0065] like Figure 2 and Figure 3 As shown, the lower ejection tube mechanism 1 includes a lower ejection tube 11, a lower nozzle 12, blades 13, a first transmission member 14, and a first rotary drive 15. The lower ejection tube 11 is connected to the lower nozzle 12, which is rotationally connected to the swing mechanism 2. The blades 13 are internally mounted in the lower ejection tube 11, and the two are coaxially arranged. The first transmission member 14 is arranged along the circumference of the lower ejection tube 11, and the first rotary drive 15 is transmission-connected to the first transmission member 14 to drive the lower ejection tube 11 to rotate about its axis. Specifically, the lower nozzle 12, which serves as the snow outlet for the lower ejection tube 11, can be integrated with the lower ejection tube 11. Snow transported from the outside is discharged into the lower ejection tube 11, and the blades 13 provide power to enhance the fluidity of the snow within the lower ejection tube 11, allowing it to be quickly discharged through the lower nozzle 12. The first transmission member 14 can be a rack, a chain, or multiple pins, wherein the multiple pins are arranged in an array around the axis of the lower ejection tube 11 to form a rack-like structure. The first rotary driver 15 can be an electric motor or a motor. The rotating shaft of the first rotary driver 15 is connected with a gear or a sprocket so as to be able to engage with the first transmission member 14 for transmission. By driving the first rotary driver 15 to rotate, the lower throwing tube 11 can be driven to rotate around its axis, thereby realizing the separate rotation of the lower throwing tube mechanism 1 and the swing mechanism 2. The rotations of the two do not interfere with each other. When the lower throwing tube mechanism 1 and the upper throwing tube mechanism 3 are connected, they can be adjusted synchronously, and the adjustment efficiency is high.

[0066] Secondly, multiple sliders 111 are arranged circumferentially around the lower throwing cylinder 11; chute grooves are provided on the swing mechanism 2; and the sliders 111 are slidably connected to the chute grooves. In this embodiment, the sliders 111 are copper sheets, and the chute grooves are correspondingly configured as concave or L-shaped grooves to cooperate with the sliders 111 in transmission. The provision of the sliders 111 reduces wear between the lower throwing cylinder 11 and the swing mechanism 2, providing a self-lubricating effect and extending the service life of the device.

[0067] See also Figure 4The swing mechanism 2 includes a second rotary drive 21, a third rotary drive 22, a second transmission member 23, a pair of brackets 24 and a pair of connecting rings 25; the pair of brackets 24 are connected by the second transmission member 23, and the second rotary drive 21 is transmission-connected to the second transmission member 23; the pair of brackets 24 and the pair of connecting rings 25 are connected one-to-one; the connecting ring 25 is rotationally connected to the lower throwing tube mechanism 1; the brackets 24 are hinged to the upper throwing tube mechanism 3; the third rotary drive 22 is arranged on the brackets 24, and the third rotary drive 22 can drive the upper throwing tube mechanism 3 to swing around the hinge point. The first transmission member 14, the second transmission member 23, the third transmission member 32 and the fourth transmission member 37 of the present invention can all be selected from racks, chains or rack-like structures with multiple pins. The specific transmission length size can be set as required, as long as the adjustment requirements are met; the first rotary drive 15, the second rotary drive 21, the third rotary drive 22 and the fourth rotary drive 36 can all be selected from motors.

[0068] In this embodiment, the second transmission member 23 utilizes multiple pins, connected by a pair of connecting rings 25. These pins serve both as a connection and as a rack-like structure, enabling meshing and transmission with the second rotary actuator 21. The multiple pins form an arcuate stopper, allowing the lower nozzle 12 to swing within the non-arc-shaped stopper of the pair of connecting rings 25 in the circumferential direction, thereby adjusting the spray height and direction of the lower nozzle 12. The bracket 24 has a triangular structure, which provides enhanced stability and improves the support stability of the swing mechanism 2 on the upper throwing tube mechanism 3. The bottom end of the bracket 24 is arc-shaped and connects to the circumferential end surface of the lower throwing tube 11. The shape of the connecting surface matches, further enhancing support stability. The top end of the bracket 24 is hingedly connected to the upper throwing tube mechanism 3. The third rotary actuator 22 is mounted in the middle of the bracket 24, enabling the third rotary actuator 22 to drive the upper throwing tube mechanism 3 to rotate about the hinge point at the top end of the bracket 24.

[0069] like Figure 5As shown, the upper ejection tube mechanism 3 includes a base 31, a third transmission member 32, a docking tube 33, a connecting tube 34, and a snow throwing cap 35. The third transmission member 32 is disposed on the base 31 and is in transmission connection with the swing mechanism 2. The base 31 is hinged to the swing mechanism 2, and the swing mechanism 2 can drive the base 31 to swing about the hinge point between the two. One end of the connecting tube 34 is connected to the snow throwing cap 35, and the other end is connected to the docking tube 33. The docking tube 33 can dock with the lower ejection tube mechanism 1. Specifically, the base 31 is an arc-shaped base 31. The third transmission member 32 can be configured as an arc-shaped rack. Alternatively, the base 31 and the third transmission member 32 can be integrated, that is, the base 31 is configured as a sprocket structure to achieve meshing transmission with the third rotary drive 22. The docking tube 33 docks with the lower nozzle 12, and the connecting tube 34 can extend the snow discharge path. The specific length can be set as required. The snow is finally discharged from the snow throwing device through the snow throwing cap 35.

[0070] In order to improve the docking accuracy between the docking tube 33 and the lower nozzle 12 and reduce the docking gap, a sensor can be set on the docking tube 33 or the lower nozzle 12, which can be a pressure sensor or a displacement sensor, to reduce the gap between the docking tube 33 and the lower nozzle 12 after the two are docked. This can effectively prevent snow from being discharged from the gap, reduce the intensity of subsequent cleaning work, and improve snow removal efficiency.

[0071] Secondly, the upper ejection tube mechanism 3 also includes a fourth rotary driver 36 and a fourth transmission member 37. The docking tube 33 is rotatably connected to the connecting tube 34. The fourth transmission member 37 is sleeved on the connecting tube 34. The fourth rotary driver 36 is in transmission connection with the fourth transmission member 37 to drive the connecting tube 34 to rotate about the axis of the fourth transmission member 37. The fourth rotary driver 36 can drive the connecting tube 34 and the snow throwing cap 35 to rotate synchronously. The rotation axis is the axis of the fourth transmission member 37. This allows the snow throwing direction of the snow throwing cap 35 to be adjusted at the same height, improving the adaptability of the snow throwing device to different construction sections.

[0072] The upper ejector mechanism 3 also includes a telescopic actuator 38 and an articulated rod. The connecting tube 34 and the snow throwing cap 35 are hingedly connected via the articulated rod. One end of the telescopic actuator is hinged to the connecting tube 34, and the other end is articulated to the snow throwing cap 35. The telescopic actuator 38 is capable of driving the snow throwing cap 35 to rotate about the articulated rod. The telescopic actuator 38 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod to drive the snow throwing cap 35 about the articulated rod, further increasing the adjustable range of the snow throwing angle and enhancing its adaptability to different construction sections.

[0073] See also Figure 6The present invention also provides a snow thrower, comprising the aforementioned snow thrower device with an adjustable throwing barrel angle, a positioning device 4, a snow collecting device 5, and a power unit 6. The snow collecting device 5, the power unit 6, and the snow thrower are all mounted on the positioning device 4. The snow collecting device 5 is connected to the lower throwing barrel mechanism 1, and the power unit 6 is connected to the lower throwing barrel mechanism 1. The positioning device 4 is used to position the various devices. The snow thrower can be mounted on a snowplow through the positioning device 4 to perform snow removal operations as the snowplow moves. In this embodiment, a first rotary drive 15 and a second rotary drive 21 are mounted on the positioning device 4 to improve transmission stability. The power unit 6 is in transmission connection with the blades 13 to drive the blades 13 to rotate about their axes.

[0074] During actual operation, as the snowplow moves, the snow collecting device 5 collects the snow on the route. The snow collecting device 5 can be provided with a push shovel to guide the snow to facilitate the collection of the snow; the power device 6 is turned on to rotate the blades 13, which not only improves the adsorption force of the snow collecting device 5 on the snow, improves the snow collecting efficiency of the snow collecting device 5, but also enhances the fluidity of the snow in the snow throwing device, so that the snow is quickly discharged from the lower throwing cylinder mechanism 1 or discharged after being compressed by the upper throwing cylinder mechanism 3.

[0075] Furthermore, the present invention also provides a method for adjusting a snow throwing device with an adjustable throwing barrel angle. The method for adjusting a snow throwing device with an adjustable throwing barrel angle is implemented based on the above-mentioned snow throwing device with an adjustable throwing barrel angle, and the method comprises:

[0076] Only the lower throwing barrel mechanism 1 is enabled for operation: the lower throwing barrel mechanism 1 rotates around its own axis to adjust the snow discharge angle of the lower throwing barrel mechanism 1, thereby achieving snow throwing operation toward the left or right side of the snowplow;

[0077] The upper and lower throwing tube mechanisms 3 and 1 operate in tandem: the swing mechanism 2 drives the upper throwing tube mechanism 3 to a vertical position; the lower throwing tube mechanism 1 rotates about its own axis, docking the upper and lower throwing tube mechanisms 3 and 1; and the lower throwing tube mechanism 1 and the swing mechanism 2 swing in unison. Specifically, after docking, the lower nozzle 12 and docking tube 33 connect, allowing the snow in the lower throwing tube mechanism 1 to be ejected through the snow ejection cap 35 of the upper throwing tube mechanism 3. Conventional snow throwers' upper throwing tubes can only dock with the lower throwing tube 11 in a vertical, upward position, making it difficult to adjust the height of the upper throwing tube's snow outlet, and the discharged snow is easily blown away by headwinds. In this embodiment, the upper ejection barrel mechanism 3 includes a vertical state and a horizontal state. In the horizontal state, the upper ejection barrel mechanism 3 faces the left or right side of the snowplow, that is, the axis of the upper ejection barrel mechanism 3 is substantially parallel to the horizontal plane. At this time, the upper ejection barrel mechanism 3 will not affect the independent operation of the lower ejection barrel mechanism 1; in the vertical state, the upper ejection barrel mechanism 3 faces vertically upward, that is, the axis of the upper ejection barrel mechanism 3 is substantially parallel to the vertical plane. After the third rotary drive 22 is locked, the lower ejection barrel mechanism 1 can be driven to rotate by the first rotary drive 15 to achieve docking of the lower nozzle 12 and the docking barrel 33. After docking, the first rotary drive 15 and the second rotary drive 21 are driven simultaneously to achieve the linkage adjustment of the lower ejection barrel mechanism 1 and the upper ejection barrel mechanism 3, and finally achieve the joint swing of the upper and lower ejection barrel mechanisms to achieve the adjustment of the height of the snow throwing cap 35.

[0078] It should be noted that a limiting structure is typically provided on the docking tube 33 or the lower spout 12, such as extending the length of one end of the bottom surface of the docking tube 33, to limit the unidirectional swing of the lower spout 12, thereby reducing the docking precision requirements of the docking interface and improving the sealing effect of the docking interface. Therefore, the upper throwing tube mechanism 3 must be adjusted to a vertical state before the lower throwing tube mechanism 1 can be docked with the upper throwing tube mechanism 3, otherwise interference is likely to occur.

[0079] Secondly, when only the lower throwing tube mechanism 1 is enabled for operation, the swing mechanism 2 drives the upper throwing tube mechanism 3 to swing around the hinge point of the two to a horizontal state, that is, a non-vertical state, which can effectively avoid the interference between the lower throwing tube mechanism 1 and the upper throwing tube mechanism 3 during operation, and ensure that the snow thrown from the lower nozzle 12 will not enter the upper throwing tube mechanism 3, thereby improving the operation efficiency.

[0080] It should be understood that the above description of the specific embodiments of the present invention is merely for the purpose of illustrating the technical approach and features of the present invention. Its purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly.
