Description

Technical Field

[0001] The present invention relates to the technical field of snow removal equipment, in particular to a snow discharge direction adjustment assembly and also to a snow sweeper. Background Art

[0002] Snow blower is a kind of snow removal equipment. It can greatly reduce the labor intensity of manpower and improve the efficiency of snow removal.

[0003] When the existing snow blower is in operation, the snow on the ground is transported and thrown out from the snow discharge barrel on the top of the snow blower to the side of the road. The snow discharge barrel is usually steerable to facilitate the adjustment of the snow throwing direction. At present, the snow discharge barrel often uses a motor and a gear set to achieve the steering function. During the snow discharge process of the snow discharge barrel, wind blows the snow onto the rotating parts (such as gears); the motor generates heat when it is running, and the heat causes the snow on the rotating parts (such as gears) to melt and then freeze. When the motor is used to drive the snow discharge barrel to turn again, the frozen rotating parts (such as gears) are prone to cause the motor to get stuck or lack power. The motor is prone to overheating and burning if it works under such conditions for a long time. Summary of the invention

[0050] See also Figures 1 to 8 The present embodiment provides a snow discharge direction adjustment assembly, including a snow discharge barrel 10, a gear set 20, a flexible shaft 30 and a driving mechanism 40.

[0051] The snow discharge barrel 10 is rotatably mounted on the snowplow. The gear set 20 is used to drive the snow discharge barrel 10 to rotate. The snow discharge barrel 10 and the gear set 20 adopt the existing technology. The gear set 20 consists of a gear ring and a transmission gear. The gear ring is rotatably arranged at the snow outlet of the snowplow. The snow discharge barrel is fixedly connected to the gear ring. The lower end surface of the gear ring is provided with gear teeth around the circle and meshes with the transmission gear. The transmission gear is rotatably arranged on the snowplow. The flexible shaft 30 is used to drive the gear set 20 (the flexible shaft drives the transmission gear to rotate). The driving mechanism 40 is used to manually drive the rotating shaft to rotate.

[0052] In this embodiment, the flexible shaft 30 is manually driven forward and reverse by the driving mechanism 40, so as to control the snow discharge barrel 10 to adjust the snow throwing direction through the gear set 20; compared with a snowplow in which the snow discharge barrel 10 is driven to rotate by a motor, the motor can be prevented from getting stuck and having insufficient power after the gear set 20 is frozen, and the motor can also be prevented from burning out due to getting stuck for a long time or having insufficient power; in addition, by driving the flexible shaft 30 to rotate forward and reverse repeatedly, the gear teeth of the gear ring of the gear set 20 and the gears of the transmission gear are repeatedly meshed back and forth, so that the ice on the gear set 20 can be broken and the steering function of the snow discharge barrel 10 can be restored.

[0053] In the prior art, there is also a method of pulling a rope to drive the snow discharge barrel 10 to rotate, and the snow discharge barrel 10 can be driven to rotate by pulling the two sections of the rope. In the prior art, there is also a method in which a control rod is rotatably arranged on a handle connecting rod of a snow sweeper, and the end of the control rod is connected to a connecting rod through a universal joint, and the connecting rod is connected to a gear set 20 to realize the rotation of the snow discharge barrel 10. In comparison, the flexible shaft 30 can be simplified in the transmission structure.

[0054] In one embodiment, the driving mechanism 40 includes a mounting seat 41 , a screw rod 42 and a nut 43 .

[0055] The mounting seat 41 is arranged on the snowplow handle connecting rod 50. The handle connecting rod is a structure that connects the handle to the snowplow body. The operator holds the handle and pushes the snowplow body to move through the handle connecting rod. The screw 42 is rotatably arranged on the mounting seat 41. The nut 43 is slidably arranged on the mounting seat 41, and the nut 43 is threadedly connected with the screw 42, and the screw 42 is operated to rotate by sliding the nut 43. One end of the screw 42 is connected to the end of the flexible shaft 30. The end of the screw 42 is provided with a straight prism hole or a rectangular hole or other special-shaped holes along its axial center line, and the end (two ends) of the flexible shaft 30 is fixedly connected with a docking prism block or a docking rectangular column or other docking special-shaped column. When installing, the docking prism block or the docking rectangular column or other docking special-shaped column is inserted into the prism hole or the rectangular hole or other special-shaped hole, which is convenient for installation. In one embodiment, the nut 43 is sleeved outside the screw 42, and a steel ball is arranged inside the nut 43, and the screw 42 and the nut 43 form a ball screw.

[0056] In addition, the size of the docking prism block or docking rectangular column or other docking special-shaped column connected to the end of the flexible shaft 30 is larger than the flexible shaft 30. A through hole is provided on the mounting seat 41 for the flexible shaft 30 to pass through, and the docking prism block or docking rectangular column or other docking special-shaped column will abut against the mouth of the through hole when the flexible shaft 30 is withdrawn, thereby preventing the flexible shaft 30 from being separated from the mounting seat 41. A connecting through hole is also provided at the transmission gear corresponding to the gear set 20 on the snowplow, and the docking prism block or docking rectangular column or other docking special-shaped column at the other end of the flexible shaft 30 passes through the connecting through hole and is connected to the transmission gear; when the other end of the flexible shaft 30 is withdrawn, its docking prism block or docking rectangular column or other docking special-shaped column abuts against the end of the connecting through hole, thereby preventing the end of the flexible shaft 30 close to the gear set 20 from being separated from the transmission gear of the gear set 20. Similar to the straight prism hole, rectangular hole or other special-shaped hole opened at the end of the screw rod 42, the transmission gear in the gear set 20 is also provided with the same hole to facilitate the connection of the other end of the flexible shaft with it. In one embodiment, both ends of the flexible shaft 30 are provided with docking prism blocks, the end of the screw rod 42 close to the flexible shaft 30 is provided with a straight prism hole for connecting the docking prism block, and the transmission gear of the gear set 20 is also provided with a straight prism hole; the docking prism blocks at both ends of the flexible shaft 30 are respectively connected to the straight prism holes of the screw rod 42 and the transmission gear, so that the screw rod 42 drives the transmission gear of the gear set 20 to rotate through the flexible shaft 30, thereby controlling the gear ring to drive the snow discharge barrel 10 to rotate.

[0057] In this embodiment, the screw rod 42 is driven to rotate by manually driving the nut 43 to move back and forth linearly, thereby driving the flexible shaft 30 to rotate. The nut 43 can drive the flexible shaft 30 to rotate forward multiple times and then reverse multiple times by one reciprocating movement. After the gear column 20 of the snow discharge barrel 10 is frozen, the nut 43 can be manually driven to move back and forth in a small range, driving the flexible shaft 30 to rotate forward and reverse in a small range, thereby impacting the frozen part of the gear set 20. After the frozen part of the gear set 20 is slightly broken, the reciprocating movement of the nut 43 is increased, so that the frozen part of the gear set 20 is subjected to a greater impact, so as to remove the ice on the gear set 20, thereby restoring the steering function of the snow discharge barrel 10. The mounting seat 41 can be installed on the snowplow handle connecting rod 50 by bolts.

[0058] The manual drive nut 43 moves back and forth, and the force is applied naturally, conveniently and quickly, thereby forming a higher frequency and stronger impact on the ice position of the gear group 20 of the snow discharge tube 10, which is beneficial to breaking the ice at the gear group 20 of the snow discharge tube 10.

[0059] In addition, as the degree of breaking of the frozen position of the gear group 20 of the snow discharge tube 10 increases, the distance that the nut 43 can move back and forth increases, so that the nut 43 can obtain greater inertia during the movement, so that the rotation of the flexible shaft 30 has greater inertia, providing greater impact force, which is beneficial to breaking the frozen position of the gear group 20 of the snow discharge tube 10.

[0060] In addition, the reciprocating distance of the nut 43 can be set longer, thereby further improving the inertia of the nut 43 in the reciprocating movement; at the same time, this setting can also produce the following effects when the gear set 20 of the snow discharge tube 10 is not frozen and daily steering adjustment is performed:

[0061] The steering angle range of the snow discharge cylinder 10 is fixed. As the reciprocating distance of the nut 43 increases, the pitch increases accordingly. The distance the nut 43 moves corresponding to each rotation of the snow discharge cylinder 10 by 1 degree increases, thereby making it more accurate to adjust the steering of the snow discharge cylinder 10 through the nut 43.

[0062] There are multiple spiral grooves on the screw rod 42, and multiple spiral long strip protrusions are provided on the inner wall of the nut 43. The multiple long strip protrusions are slidably matched with the multiple spiral grooves at the same time, so that the nut 43 and the screw rod 42 are closely matched and the transmission is stable.

[0063] In one embodiment, the mounting seat 41 is provided with a plurality of locking grooves 411 arranged along the axial direction of the screw rod 42 .

[0064] The driving mechanism 40 further includes an armrest seat 44 , a locking member 45 and a compression spring 46 .

[0065] One end of the armrest seat 44 is connected to the nut 43. The middle part of the locking member 45 is hinged to the armrest seat 44, and one end of the locking member 45 can be inserted into the corresponding locking groove 411. The compression spring 46 is arranged on the armrest seat 44, one end of the compression spring 46 abuts against the armrest seat 44, and the other end of the compression spring 46 abuts against one end of the locking member 45 away from the locking groove 411.

[0066] In this embodiment, the end of the locking member 45 is inserted into the locking groove 411 under the action of the compression spring 46, thereby locking the nut 43 and the mounting seat 41. When unlocking is required, the end of the locking member 45 away from the locking groove 411 can be pressed to unlock.

[0067] In one embodiment, a mounting cavity 412 is provided on the mounting seat 41. The entire base is in an elongated strip shape, and the mounting cavity 412 is also in an elongated strip shape. The screw rod 42 is rotatably arranged in the mounting cavity 412. Both sides of the mounting seat 41 are provided with a clearance groove 413 extending along the axial direction of the screw rod 42. The nut 43 is located in the mounting cavity 412, and the ends of the armrest seat 44 pass through the clearance groove 413 from both sides and are connected to the nut 43.

[0068] In this embodiment, the screw rod 42 and the nut 43 are located in the installation cavity 412, which can reduce the adhesion of dust to the screw rod 42, protect the screw rod 42 and the nut 43, and extend the service life.

[0069] In one embodiment, a locking hole 441 is formed on the armrest seat 44 ; an end of the locking member 45 can pass through the locking hole 441 and then be inserted into the corresponding locking groove 411 .

[0070] In this embodiment, the lower end of the locking member 45 is inserted into the locking groove 411 through the locking hole 441 , so that the armrest seat 44 together with the nut 43 connected thereto and the mounting seat 41 can be locked more firmly.

[0071] In one embodiment, the armrest seat 44 is located above the mounting seat 41. A mounting hole 442 is provided on the armrest seat 44. The compression spring 46 is located in the mounting hole 442. The orifice of the mounting hole 442 corresponds to an end of the locking member 45 away from the locking groove 411.

[0072] In the present embodiment, when the armrest seat 44 is manually operated to move back and forth, the palm of the hand contacts the end of the armrest seat 44 away from the mounting seat 41, the fingers grasp the armrest seat 44 in a claw shape, and the thumb is placed on the locking piece 45; the upper end of the locking piece 45 is pressed with the thumb to unlock it, and the armrest seat 44 can be operated with one hand to drive the nut 43 to move back and forth in a straight line, which is more convenient.

[0073] In one embodiment, a first mounting groove 414 extending along the axial direction of the screw rod 42 is formed on one side of the mounting seat 41 close to the armrest seat 44; a second mounting groove 443 extending along the axial direction of the screw rod 42 is formed on one side of the armrest seat 44 facing the mounting seat 41; the first mounting groove 414 can be fitted with the snowplow handle connecting rod 50, and the second mounting groove 443 can be loosely fitted with the snowplow handle connecting rod.

[0074] In this embodiment, when the mounting seat 41 and the armrest seat 44 are mounted on the handle connecting rod, the first mounting groove 414 and the second mounting groove 443 can achieve a positioning function, which facilitates installation.

[0075] In one embodiment, arc-shaped guide plates 47 are connected to both sides of the armrest seat 44; the arc-shaped end faces of the arc-shaped guide plates 47 are used to fit with the clearance between the snowplow handle connecting rod 50. When the armrest seat 44 is manually forced, the armrest seat 44 moves axially along the snowplow handle connecting rod 50, and at this time, the two arc-shaped guide plates 47, the armrest seat 44 and the nut 43 slide on the mounting seat 41. In addition, when the two sides of the lower end of the armrest seat 44 pass through the clearance groove 413 respectively, they slide and fit with the clearance groove 413 along the axial direction of the screw rod 42, so that the axial movement of the armrest seat 44 and the nut 43 along the screw rod 42 is more stable.

[0076] In one embodiment, the snow discharge direction adjustment assembly further includes a hose 31. The hose 31 is sleeved outside the flexible shaft 30 with a gap.

[0077] In this embodiment, the hose 31 wraps the flexible shaft 30 to prevent the rotating flexible shaft 30 from interfering with the outside.

[0078] This embodiment provides a snowplow, comprising any one of the above-mentioned snow discharge direction adjustment assemblies.
