Description

Technical Field

[0001] The invention relates to the field of mechanical equipment, and in particular to a snowplow. Background Art

[0002] Snowplows, also known as snow blowers and snow throwers, have strong power, strong snow suction, and a snow throw height of 10-15 meters. They can move and reverse automatically, and the operator only needs to control the direction. This advanced snow-clearing and snow-sweeping machine is particularly suitable for northern my country. It is an essential machine for winter snow clearing and sweeping, and is widely used in government agencies, units, schools, parking lots, squares, property communities, gardens, non-motorized vehicle lanes, etc.

[0003] The snowplow in the prior art usually includes a snowplow housing, snow-shoveling blades and a transmission mechanism; the transmission mechanism includes a support shaft and a motor, pulley I and pulley II arranged in the snowplow housing; the support shaft is fixed on the snowplow housing, and the snow-shoveling blades are sleeved on the support shaft; pulley I is arranged on the motor, and pulley I and pulley II are connected by a belt.

[0004] The above-mentioned snowplow has the following disadvantages:

[0005] 1. When the transmission mechanism is working, the motor drives the pulley I to rotate, and the pulley I drives the pulley II to rotate through the belt. Since the pulley II and the snow-shoveling fan blades are both mounted on the support shaft, the cross-section of the support shaft is polygonal, and the pulley II and the snow-shoveling fan blades are both interference fit with the support shaft. Therefore, the pulley II drives the support shaft to rotate, and the support shaft drives the snow-shoveling fan blades to rotate. The snow-shoveling fan blades of this transmission mechanism are difficult to rotate, and the motor needs a lot of power to rotate the snow-shoveling fan blades. Its transmission efficiency is poor and energy consumption is high. In addition, since the pulley II and the snow-shoveling fan blades are both mounted on the support shaft, the rotation of the snow-shoveling fan blades is driven by the support shaft, and there is an interference fit between the snow-shoveling fan blades and the support shaft. Therefore, the snow-shoveling fan blades and the support shaft are very tight. When the snow-shoveling fan blades are worn or even damaged and need to be replaced, the snow-shoveling fan blades mounted on the support shaft are difficult to disassemble and install.

[0006] 2. The motor in the snowplow casing is usually directly fixed on the inner wall of the snowplow casing. Since the motor will vibrate when working and the contact area between the snowplow motor and the inner wall of the snowplow casing is large, the vibration is directly transmitted to the snowplow casing, causing loud vibration noise and easily causing damage to the snowplow casing. Moreover, the snowplow casing is an integral part. After the outer shell of the snowplow is damaged, it can only be replaced as a whole. Not only is the replacement difficult, but the replacement cost is also high.

[0007] 3. There is no snow removal baffle. The snow shoveled by the snowplow during the snowplowing process is easily thrown in front of the snowplow's route, causing the snow on the snowplow's route to accumulate thicker and thicker, thereby increasing the snow removal work of the snowplow in the later stage. Summary of the invention

[0008] The purpose of the present invention is to provide a snowplow, which can reduce the difficulty and cost of replacing the snowplow casing; during operation, the snowplow has low overall operating noise, and the transmission mechanism has high transmission efficiency and low energy consumption.

[0009] The objective of the present invention is achieved in this way. A snowplow comprises a hand-held handle, a driving mechanism, snow-shoveling blades, a motor, a transmission mechanism, a snowplow casing and a walking mechanism fixed under the snowplow casing, a support shaft being fixed to the front end of the snowplow casing; the snowplow casing comprises a cover casing and a fixing plate, a through hole corresponding to the position and matching the size of the fixing plate is opened on the cover casing, and the fixing plate is arranged in the through hole; the driving mechanism is fixed to the hand-held handle; the snow-shoveling blades are sleeved on the support shaft and connected to the motor through a transmission mechanism, the transmission mechanism comprises a belt, a pulley I and a pulley II for driving the snowplow blades to rotate, the rotating shaft of the motor passes through the fixing plate to drive the pulley I to rotate, and the pulley I and the pulley II are connected by a belt; the driving mechanism and the motor are electrically connected.

[0010] In the present invention, when in use, the motor drives pulley I to rotate, and pulley I drives pulley II to rotate through the belt. Since a groove is provided at the right end of the snow shoveling fan blade, pulley II is arranged in the groove and drives the snow shoveling fan blade to rotate. When pulley II rotates to drive the snow shoveling fan blade to rotate, the snow shoveling fan blade of the transmission mechanism is easy to rotate, so it has high transmission efficiency and low energy consumption; pulley II is only connected to the groove part of the snow shoveling fan blade, and the support shaft only plays a role in supporting bearing I and bearing II. Therefore, when the snow shoveling fan blade is worn or even damaged and needs to be replaced, the snow shoveling fan blade sleeved on the support shaft is easy to disassemble and install.

[0011] The motor of the snowplow passes through the shaft hole, and the motor is fixed to the fixing plate through the fixing hole I. The fixing plate is fixed to the side wall of the snowplow housing corresponding to the motor in the snowplow through the fixing hole II. The snowplow housing includes a cover and a fixing plate. The cover is provided with a through hole corresponding to the position and size of the fixing plate. The fixing plate is arranged in the through hole, so it can reduce the noise transmitted to the snowplow housing when the motor is running, thereby reducing the operating noise of the entire snowplow. Moreover, the vibration of the motor can only damage the fixing plate at most. The difficulty and cost of replacing the fixing plate after it is damaged are relatively low, so the difficulty and cost of replacing the outer shell of the snowplow can be reduced.

[0012] Due to the adoption of the above-mentioned technical scheme, the present invention has the following advantages: the snow-shoveling fan blades are easy to disassemble and install, and the difficulty and cost of replacing the snowplow casing are reduced; during operation, the overall operation noise of the snowplow is low, and the transmission efficiency and energy consumption of the transmission mechanism are high; in addition, during the snow removal process of the snowplow, the snow shoveled by the snowplow can be thrown to both sides of the snowplow, avoiding the snow being thrown in front of the snowplow's travel route, causing the snow on the snowplow's travel route to accumulate thicker and thicker, thereby avoiding excessive snow accumulation affecting the snow removal work of the snowplow in the later stage.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0028] like Figures 1 to 12 As shown, a snowplow comprises a hand-held handle 41, a driving mechanism 42, snow-shoveling blades 6, a motor 2, a transmission mechanism, a snowplow casing and a walking mechanism 43 fixed below the snowplow casing, a support shaft 5 is fixed to the front end of the snowplow casing; the snowplow casing comprises a cover casing 1 and a fixing plate 31, a through hole 40 corresponding to the position and matching the size of the fixing plate 31 is opened on the cover casing 1, and the fixing plate 31 is arranged in the through hole 40; the driving mechanism 42 is fixed on the hand-held handle 41; the snowplow blades 6 are sleeved on the support shaft 5 and connected to the motor 2 through a transmission mechanism, the transmission mechanism comprises a belt 7, a pulley Ⅰ3 and a pulley Ⅱ4 for driving the snowplow blades 6 to rotate, the rotating shaft of the motor 2 passes through the fixing plate 31 to drive the pulley Ⅰ3 to rotate, and the pulley Ⅰ3 and the pulley Ⅱ4 are connected by a belt 7; the driving mechanism 42 and the motor 2 are electrically connected.

[0029] In the present invention, when in use, the motor 2 works to drive the pulley I3 to rotate, and the pulley I3 drives the pulley II4 to rotate through the belt 7. Therefore, the rotation of the pulley II4 drives the snow shoveling blades 6 to rotate. The snow shoveling blades 6 of the transmission mechanism are easy to rotate, so its transmission efficiency is high and the energy consumption is small.

[0030] The snowplow housing includes a cover 1 and a fixing plate 31. The cover 1 is provided with a through hole 40 corresponding to the position and size of the fixing plate 31, and the fixing plate is arranged in the through hole 40. Therefore, the fixing plate 31 can reduce the noise transmitted from the motor 2 to the snowplow housing when the motor 2 is running, thereby reducing the operating noise of the entire snowplow. Moreover, the vibration of the motor can only damage the fixing plate at most. The difficulty and cost of replacing the fixing plate after it is damaged are relatively low, thus reducing the difficulty and cost of replacing the snowplow housing.

[0031] In this embodiment, the handle 41 is fixed on the snowplow housing, the driving mechanism 42 is a battery 46 fixed to the upper part of the handle 41 through a fixing shell 45, and the walking mechanism 43 is a mechanism with wheels fixed under the snowplow housing and capable of facilitating the walking of the snowplow.

[0032] Furthermore, in this embodiment, a hand ring 44 is fixed on the hand handle 41. The function of the hand ring 44 is to facilitate the operator to hold the snow blower.

[0033] Furthermore, the hand handle 41 has an arc. The hand handle 41 has a certain arc, which not only conforms to human mechanics, so that the operator does not need to bend down when using it, but also can balance the weight of the driving mechanism 42 and the snowplow housing part, so as to avoid the snowplow from tipping over easily when placed. In this embodiment, the driving mechanism is a lithium battery holder with a lithium battery.

[0034] Furthermore, the cover 1 is provided with a locking mechanism 13 and a baffle 16 with a protrusion I 14 and a protrusion II 15; the locking mechanism 13 includes a horizontal plate 17, a spring 18, a rotating rocker arm 19 and a fixed plate 21 with two or more slots 20 on the bottom surface arranged in sequence from bottom to top; the baffle 16 is rotatably fixed under the horizontal plate 17 through the protrusion I 14; the rotating rocker arm 19 includes a rotating pressing rod 22 and a rotating block 24 fixed under the rotating pressing rod 22 and having a clamping member 23, the clamping member 23 corresponds to the slot 20, and a protrusion hole 25 is also opened on the rotating block 24, and the protrusion II 15 is fixed in the protrusion hole 25; a through hole 26 is also opened on the fixed plate 21, and the rotating pressing rod 22 is movably arranged in the through hole 26; the protrusion I 14 is rotatably fixed in the horizontal plate 17. In the present invention, the fixed plate 21 and the horizontal plate 17 are both fixed above the snow shoveling blade of the snow remover 1. The correspondence between the clamping piece 23 and the slot 20 means that when the spring 18 is not compressed and the clamping piece 23 is stuck in the slot 20, the rotating rocker arm 19 is fixed together with the fixed plate 21. At this time, the rotating pressing rod 22 cannot be rotated, and the rotating rocker arm 19 cannot be rotated either; when the spring 18 is compressed and the clamping piece 23 is out of the slot 20, the rotating rocker arm 19 is separated from the fixed plate 21. At this time, the rotating pressing rod 22 can be rotated, and the rotating rocker arm 19 can also be rotated.

[0035] When in use, the rotating pressing rod 22 is pressed to compress the spring 18, and the clamping piece 23 is disengaged from the clamping groove 20, and then the rotating pressing rod 22 is rotated to rotate the rotating block 24, and the rotating block 24 rotates through its protruding hole 25 to drive the protrusion II 15 to rotate. Since the protrusion I 14 is rotated and fixed in the horizontal plate 17, the rotating block 24 will eventually drive the baffle 16 to swing left or right. When the baffle 16 swings to tilt to the left or right and is fixed, the snow shoveled by the snowplow 1 during the snow shoveling process will be thrown to the left or right under the obstruction of the baffle 16, so as to prevent the snow from being thrown in front of the snowplow 1 and causing the snow on the snowplow 1 to accumulate thicker and thicker, thereby preventing the excessive accumulation of snow from affecting the snow removal work of the snowplow 1 in the later stage.

[0036] In this embodiment, the protrusion I14 is rotatably fixed in the transverse plate 17 by means of screws.

[0037] Furthermore, the slots 20 include three, the horizontal plate 17 is provided with a rotation hole 27, and the protrusion II 15 passes through the rotation hole 27 and is fixed in the protrusion hole 25. In this embodiment, in order to make the raised snow along the baffle 16 better thrown to both sides of the snowplow 1's travel route when shoveling snow, among the three slots 20, the middle slot 20 is parallel to the travel direction of the snowplow 1, and the acute angles between the slots 20 on both sides and the middle slot 20 are 45°. In other embodiments, the angle between the slots 20 and the slots 20 can also be other degrees, and the middle slot 20 can also be parallel to the travel direction of the snowplow 1. In other embodiments, the number of the slots 20 is other. The function of the rotation hole 27 is to limit the rotation angle of the rotating rocker arm 19, so as to better control the direction of the baffle 16, so that the baffle 16 can achieve the purpose of swinging left and right instead of rotating it to the left or right.

[0038] Furthermore, a rotating connecting arm 28 with one or more protrusion holes 25 is included, the number of baffles 16 includes one or more, the protrusion I14 of each baffle 16 is rotatably fixed in the horizontal plate 17, and the protrusion II15 of each baffle 16 is fixed in the corresponding protrusion hole 25. In this embodiment, three baffles 16 are included side by side. The protrusion II15 matches the protrusion hole II36, and the protrusion II15 of each baffle 16 is fixed in the corresponding protrusion hole II36 by screws. Among them, at least one protrusion II15 passes through the protrusion hole II36 and is set in the protrusion hole 25.

[0039] Furthermore, a shaft hole 32 and a fixing hole I 33 are provided in the middle of the fixing plate 31, and a fixing hole II 34 is provided at the edge of the fixing plate 31; the motor 2 corresponds to the fixing plate 32, the shaft of the motor 2 passes through the shaft hole 32, the fixing plate 31 is fixed to the motor 2 by a fastener passing through the fixing hole I 33, and the fixing plate 31 is also fixed to the housing 1 by a fastener passing through the fixing hole II 34. The fixing plate 31 is simple and convenient to install, and has low cost.

[0040] Furthermore, a groove 8 is provided at the right end of the snow shoveling blade 6, and a pulley II4 is disposed in the groove 8 and drives the snow shoveling blade 6 to rotate. The pulley II4 is sleeved on the right end of the support shaft 5 through a bearing I9, and the left end of the snow shoveling blade 6 is sleeved on the left end of the support shaft 5 through a bearing II10. Since the groove 8 is provided at the right end of the snow shoveling blade 6, and the pulley II4 is disposed in the groove 8 and drives the snow shoveling blade 6 to rotate, the pulley II4 is only connected to the groove 8 part of the snow shoveling blade 6, and the support shaft 5 only plays a role in supporting the bearing I9 and the bearing II10, so when the snow shoveling blade 6 is worn or even damaged and needs to be replaced, the snow shoveling blade 6 sleeved on the support shaft 5 is easy to disassemble and install.

[0041] Furthermore, in this embodiment, the cross section of the groove 8 is petal-shaped, and the pulley II4 disposed in the groove 8 matches the groove 8. In another embodiment, the cross section of the groove 8 is polygonal, and the pulley II4 disposed in the groove 8 matches the groove 8. In other embodiments, the snow shoveling blade 6 can also be integrated with the pulley II4. The purpose of the above-mentioned arrangement is to enable the snow shoveling blade 6 to rotate when the pulley II4 rotates and to facilitate the installation and removal of the snow shoveling blade 6.

[0042] Furthermore, the pulley II4 includes a left part and a right part. The left part drives the snow shoveling blade 6 to rotate in the groove 8 through the support shaft 5, and an annular stopper 11 is arranged between the left part and the support shaft 5; the pulley I3 is connected to the right part through the belt 7, and the bearing II10 is arranged between the right part and the support shaft 5. The stopper 11 is fixed on the support shaft 5 by bonding, inlaying, integrated setting, etc. The function of the annular stopper 11 is to further limit the pulley II4 and the snow shoveling blade 6. Prevent the pulley II4 and the snow shoveling blade 6 from moving left and right on the support shaft 5.

The purpose of providing multiple fixing holes I 33 and evenly arranged on the outer periphery of the shaft hole 32, and the purpose of providing multiple fixing holes II 34 and evenly arranged on the outer edge of the fixing plate 31 is to ensure the connection strength between the motor 2, the fixing plate 31 and the housing of the snow remover 1.

[0044] Furthermore, the number of the fixing holes I 33 is 6. The purpose of providing 6 fixing holes I 33 is to save processing costs while ensuring that the motor 2 and the fixing plate 31 are firmly fixed.

[0045] Furthermore, the number of the fixing holes II 34 is 5. The purpose of providing 5 fixing holes II 34 is to save processing costs when ensuring that the fixing plate 31 is fixed to the housing of the snow remover 1 .

[0046] Furthermore, the fixing plate 31 includes a bending portion 37 and a fixing portion 38 with an arc, and the shaft hole 32, the fixing hole I 33 and the fixing hole II 34 are all provided in the fixing portion 38. The function of the bending portion 37 is to facilitate the fixing plate 31 to quickly and accurately correspond to the side wall of the snowplow housing, avoiding the need to adjust the installation direction of the fixing plate when installing it; and secondly, to facilitate further positioning and fixing of the fixing plate on the snowplow. In this embodiment, the angle between the bending portion 37 and the fixing portion 38 is 120°-150°. The angle between the bending portion 37 and the fixing portion 38 is 120°-150°. The function is to ensure the overall structural strength and aesthetics of the fixing plate.

[0047] Further, the edge of the fixing plate 31 is also provided with a limiting opening 39. The function of the limiting opening 39 is to facilitate the fixing plate to be further limited and fixed on the snowplow. In this embodiment, the number of the limiting openings is 3.

[0048] Furthermore, the pulley Ⅱ4 runs through the outer shell of the snowplow 1, and a sealing ring 12 is provided between the pulley Ⅱ4 and the outer shell of the snowplow 1. In the present invention, the sealing ring 12 is a rubber ring sleeved on the pulley Ⅱ4. Since the motor 2 is provided in the snowplow 1 on the side of the belt 7 pulley, when the snowplow 1 is shoveling snow, the raised snow is easy to enter the outer shell of the snowplow 1 through the gap at the connection between the pulley Ⅱ4 and the outer shell of the snowplow 1, affecting the operation of the motor 2. Therefore, the sealing ring 12 is provided between the pulley Ⅱ4 and the outer shell of the snowplow 1 to prevent the snow from entering the outer shell of the snowplow 1 through the gap at the connection between the pulley Ⅱ4 and the outer shell of the snowplow 1 and affecting the operation of the motor 2.
