Description

Technical Field

[0001] The present invention relates to the technical field of snow removal, and in particular to a snow removal roller brush for a pure electric snow removal vehicle and a snow removal method. Background Art

[0002] The snow removal roller brush for pure electric snowplows is a roller brush installed on an electrically driven snowplow. It uses a rotating brush body to sweep, peel and throw the snow on the road to both sides, and then cooperates with the driving of the electric snowplow to achieve efficient snow removal operations. Compared with manual cleaning, it not only has higher cleaning efficiency, but also better cleaning effects.

Not only is the adjustment range limited, but when a part of the bristles touches the bottom surface of the concave area, the bristles in other areas will exert greater pressure on the surrounding ground, causing damage to the road surface or aggravating the wear of the bristles; in addition, when encountering compacted and agglomerated snow blocks, it will be difficult to clean or require a long time to clean, which will lead to reduced snow removal efficiency.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to solve the technical problem that when encountering slightly compacted snow blocks, it is difficult to clean or takes a long time to clean, resulting in reduced snow removal efficiency, such as Figures 1-13 As shown, the following preferred technical solutions are provided: like Figure 1 As shown, a snow removal roller brush for a pure electric snow removal vehicle includes a bracket 1, on which a mounting bracket 2 for mounting the snow removal roller brush on the pure electric snow removal vehicle is fixedly provided. Figure 2As shown, a roller 4 for transmitting power is rotatably provided on the bracket 1, a power component 3 for driving the snow removal roller brush to rotate is fixedly provided on the outer wall of one side of the mounting frame 2, and the power component 3 and the roller 4 are fixedly connected, and a rotating joint 5 for transmitting gas is fixedly provided on the outer wall of the other side of the mounting frame 2, and the connection between the air outlet end of the rotating joint 5 and the inner cavity of the roller 4 adopts a rotating setting, and an air pipe is also connected to the rotating joint 5, and the air pipe is connected to the air compressor on the pure electric snow removal vehicle. A plurality of annular mounting seats 6 are fixedly provided on the circumferential outer wall of the roller 4, and a plurality of cleaning components 7 for snow removal are provided on the annular mounting seat 6, as shown in FIG. Figure 4 and Figure 8 As shown, a pressure sensor 40 for monitoring snow removal pressure is embedded in the cleaning component 7. Figure 3 As shown, an adjusting component 8 for adjusting the extension length of the cleaning component 7 is slidably provided in the inner cavity of the roller 4, and the adjusting component 8 is elastically connected to the roller 4 through a spring 1 9. A plurality of electronic valves 1 20 and a plurality of electronic valves 2 30 are respectively provided in the inner cavity of the roller 4, and the electronic valves 1 20 and the electronic valves 2 30 are arranged alternately. A plurality of crushing components 10 for crushing compacted snow blocks are fixedly provided on the circumferential outer wall of the roller 4, and the crushing components 10 and the annular mounting seat 6 are arranged alternately.

[0025] Specifically, before removing snow, first fix the snow removal roller brush on the pure electric snow removal vehicle through the mounting bracket 2, electrically connect the power connector on the snow removal roller brush to the power supply on the pure electric snow removal vehicle, so that the power component 3 and the pressure sensor 40 can be powered normally, and then connect the rotating joint 5 to the air compressor on the pure electric snow removal vehicle through the air pipe; when removing snow, first start the power component 3 to drive the roller 4, the annular mounting seat 6 and the cleaning component 7 to rotate at high speed to achieve the effect of cleaning the snow on the road.

[0026] Case 1: If Figure 1-Figure 3 As shown, when cleaning the soft snow, the air compressor does not run, and the power component 3 only needs to drive the roller 4, the annular mounting seat 6 and the cleaning component 7 to rotate at high speed to achieve the cleaning effect of the snow on the road.

[0027] Case 2: If Figure 1-Figure 3As shown, during the snow removal process, when the soft snow is cleared, the interaction force between the pressure sensor 40, the cleaning component 7 and the soft snow is small, so the value of the pressure sensor 40 is small; when encountering slightly compacted snow blocks, the interaction force between the cleaning component 7 and the soft snow increases. At this time, the value of the pressure sensor 40 will increase. The controller (not shown in the figure) determines that the value of the pressure sensor 40 increases, starts the air compressor to generate compressed gas, and the compressed gas enters the inner cavity of the roller 4 through the air pipe and the rotating joint 5. At the same time, the electronic valve 2 30 is in a closed state, and then the electronic valve 1 20 is opened, so that the compressed gas can act on the cleaning component 7 and drive the cleaning component 7 to rotate. Through such a setting, during the snow removal process, the cleaning component 7 can not only follow the revolution of the roller 4, but also use the compressed gas to rotate, generating a compound motion, generating a compound force on the slightly compacted snow blocks, and enhancing the snow removal effect.

[0028] Furthermore, if Figure 1-Figure 3 As shown, during the snow removal process, if a relatively solid snow block is encountered, the interaction force between the cleaning component 7 and the snow will increase again. The controller (not shown in the figure) determines that when the value of the pressure sensor 40 increases again, the electronic valve 2 30 is opened while keeping the electronic valve 1 20 open. The compressed gas will contact the crushing component 10 through the electronic valve 2 30, releasing the restriction of the crushing component 10, and then using the centrifugal force generated by the high-speed rotation of the roller 4 to extend the length of the crushing component 10 and rotate synchronously. During the high-speed rotation, the crushing component 10 crushes the relatively solid snow blocks, and then cooperates with the cleaning component 7 to achieve a better cleaning effect.

[0029] Furthermore, during the snow removal process, when random, irregular concave areas appear on the road surface, the electronic valve 20 is opened. Similarly, compressed air is used to drive the adjustment component 8 to operate, and the adjustment component 8 is used to adjust the extension length of the cleaning component 7 to match the random, irregular concave areas. Moreover, the cleaning component 7 on each annular mounting seat 6 can be adjusted independently, which has a good snow removal effect compared to traditional segmented adjustment or overall adjustment.

[0030] like Figure 2 As shown, the bracket 1 includes a frame body 11, and mounting plates 12 are fixedly installed on the lower parts of the outer walls on both sides of the frame body 11. The roller 4 is rotatably installed on the two mounting plates 12, so that the roller 4 can rotate smoothly at a preset position. The rotating joint 5 is fixedly installed on one of the mounting plates 12, and the mounting plate 12 is used to support and limit the rotating joint 5 and the roller 4.

[0031] like Figure 2As shown, the power assembly 3 includes a mounting plate 31 fixedly mounted on the side wall of the frame 11, and a motor 32 is fixedly mounted on the mounting plate 31. The output shaft of the motor 32 is rotatably arranged on another mounting plate 12, and the output shaft of the motor 32 is fixedly connected to the roller 4. The motor 32 drives the roller 4 to rotate at high speed to achieve subsequent snow removal operations.

[0032] like Figure 3 As shown, the roller 4 includes a hollow roller body 41 rotatably mounted on the mounting plate 12, and an air collecting chamber 42 is provided inside the hollow roller body 41. The connection between the air inlet end of the air collecting chamber 42 and the air outlet end of the rotary joint 5 is provided with a rotary sealing arrangement. During the snow removal process, the compressed gas generated by the air compressor will enter the air collecting chamber 42 through the air pipe and the rotary joint 5, and then be distributed as needed to achieve different effects. The connection between the air inlet end of the air collecting chamber 42 and the air outlet end of the rotary joint 5 adopts a rotary sealing arrangement to ensure that there will be no air leakage during the transportation of gas. A number of partitions 43 are fixedly installed inside the hollow roller body 41, and the number of partitions 43 divides the interior of the hollow roller body 41 into a number of air inlet chambers 1 44 and a number of air inlet chambers 2 45, and the air inlet chambers 1 44 and the air inlet chambers 2 45 are arranged alternately. The air collecting chamber 42 and the air inlet chamber 1 44 are connected by an electronic gas valve 1 20, and the air collecting chamber 42 and the air inlet chamber 2 45 are connected by an electronic gas valve 2 30, as shown Figure 9-10 As shown, a pair of slide grooves 46 are opened in the inner cavity of the air inlet chamber 1 44 , and the adjustment component 8 is slidably set in the slide grooves 46 .

[0033] When it is necessary to adjust the rotation and extension length of the cleaning component 7, at this time, the electronic valve 2 30 is closed and the electronic valve 1 20 is opened. The compressed gas in the air collecting chamber 42 will enter the air inlet chamber 1 44 through the electronic valve 1 20, and then be discharged through the cleaning component 7. During the process of compressed gas discharge, the cleaning component 7 can be driven to rotate, which is used to enhance the snow removal effect; when it is necessary to encounter a sunken area on the road surface, the opening of the electronic valve 1 20 can be increased to allow more compressed gas to enter the air inlet chamber 1 44, which is used to drive the operation of the adjustment component 8, and the adjustment component 8 is used to adjust the extension length of the cleaning component 7 to remove snow from the sunken area on the road surface.

[0034] When encountering a relatively solid snow block, the electronic gas valve 2 30 is opened, and the compressed gas in the air collecting chamber 42 will enter the air inlet chamber 2 45 through the electronic gas valve 2 30, and then the compressed gas will enter the crushing assembly 10, releasing the restriction of the crushing assembly 10, and then using the centrifugal force generated by the high-speed rotation of the roller 4 to make the crushing assembly 10 extend in length and rotate synchronously, so as to crush the relatively solid snow block.

[0035] like Figure 9 and Figure 11As shown, the annular mounting seat 6 includes a fixing ring 61 fixedly mounted on the outer circumference of the hollow roller body 41, and a plurality of mounting cylinders 62 are fixedly mounted on the outer circumference of the fixing ring 61. Figure 3 As shown, the mounting tube 62 is connected to the air inlet chamber 44.

[0036] like Figure 8 As shown, the mounting cylinder 62 includes a cylinder body 621 fixedly mounted on the circumferential outer wall of the fixing ring 61, a pair of limiting grooves 622 are symmetrically opened in the inner cavity of the cylinder body 621, and the cleaning component 7 is slidably mounted in the inner cavity of the limiting grooves 622, and arc-shaped baffles 623 are respectively fixedly mounted on the side walls of the inner cavities of the two limiting grooves 622.

[0037] like Figure 8 As shown, the cleaning component 7 includes a slide 71 slidably mounted in the inner cavity of the limit groove 622, and a mounting ear 79 is fixedly mounted on the side wall of the slide 71. The mounting ear 79 is movably connected to the adjustment component 8. A pair of through grooves 72 are symmetrically opened on the slide 71. One end of the arc-shaped baffle 623 is slidably arranged inside the through groove 72. The setting of the through groove 72 will not interfere with the normal sliding of the slide 71 in the limit groove 622. The side wall of the slide 71 and the side wall of the inner cavity of the limit groove 622 are elastically connected by a spring 2 73. The arc-shaped baffle 623 is used to adjust the spring 2 73 is limited to prevent the spring 2 73 from bending during the compression process, thereby preventing the bending of the spring 2 73 from affecting the normal sliding of the slide 71. A rotating drum 74 is rotatably mounted on the slide 71, and a mounting column 75 is fixedly mounted on the top wall of the inner cavity of the rotating drum 74. Blades 76 are fixedly mounted on the circumferential outer wall of the mounting column 75. A number of air jet holes 77 are opened on the top wall of the rotating drum 74, and a number of bristles 78 are also planted on the top wall of the rotating drum 74. A pressure sensor 40 is set at the connection between the bristles 78 and the rotating drum 74, and is used for real-time detection of the interaction force between the bristles 78 and the snow.

[0038] During the snow removal process, the pressure sensor 40 is used to determine the interaction force between the bristles 78 and the snow, and thus the state of the snow can be determined, as follows: Case 1: If Figure 1-Figure 3 As shown, during the snow removal process, when the value of the pressure sensor 40 is in a smaller value range, it is judged that the snow is soft; when cleaning the soft snow, the air compressor does not run, and only the motor 32 is used to drive the roller 4, the annular mounting seat 6 and the cleaning component 7 to rotate at high speed, and the bristles 78 on the cleaning component 7 are used to continuously clean the snow on the road surface, thereby achieving the effect of clearing the snow.

[0039] Case 2: If Figure 1-Figure 3 and Figure 8As shown, during the snow removal process, when encountering slightly compacted snow blocks, the interaction force between the bristles 78 and the soft snow increases. At this time, the value of the pressure sensor 40 will increase. The controller (not shown in the figure) determines that the value of the pressure sensor 40 increases, starts the air compressor to generate compressed gas, and the compressed gas enters the inner cavity of the gas collecting chamber 42 through the air pipe and the rotary joint 5. At the same time, the electronic gas valve 2 30 is in the closed state, the electronic gas valve 1 20 is in the open state, and the compressed gas enters the air inlet chamber 1 through the electronic gas valve 1 20. 44, and then the compressed gas will pass through the slide 71 into the drum 74 and finally be discharged from the air jet hole 77. During this process, the compressed gas will drive the drum 74 to rotate on the slide 71 through the blades 76 and the mounting column 75. During the rotation of the drum 74, the bristles 78 will be driven to rotate. Through such an arrangement, during the snow removal process, the bristles 78 can not only follow the revolution of the roller 4, but the bristles 78 can also rotate by using the compressed gas to generate a compound motion, thereby generating a multi-directional compound force on the slightly compacted snow blocks, which can enhance the snow removal effect.

[0040] During the process of clearing snow, the bristles 78 may freeze on the bristles 78 due to the cold weather, which will significantly affect the snow cleaning effect. The compressed gas mentioned above is ejected through the jet hole 77, so that the compressed gas can blow off the remaining snow on the bristles 78 and reduce the amount of ice on the bristles 78. Through such a setting, the bristles 78 can still maintain a good cleaning effect during long-term use.

[0041] In order to solve the technical problem that when encountering relatively solid snow blocks, it is difficult to clean or it takes a long time to clean, resulting in reduced snow removal efficiency, such as Figure 1-Figure 3 and Figure 11-13 As shown, the following preferred technical solutions are provided: like Figure 5-Figure 6 and Figure 11-13As shown, the crushing assembly 10 includes a base 101 fixedly mounted on the circumferential outer wall of the hollow roller body 41, a pair of fixed frames 102 are fixedly mounted on the outer side wall of the base 101, and a rotating shaft 103 is mounted on the two fixed frames 102 to rotate together. A winding roller 104 is fixedly sleeved on the circumferential outer wall of the rotating shaft 103, and the winding roller 104 and the fixed frame 102 are elastically connected by a torsion spring 105.

A through groove 108 is provided inside the base 101, and the air inlet end of the through groove 108 is connected to an electronic air valve 109 fixedly mounted thereon, and the air outlet end of the branch pipeline of the through groove 108 is connected to a pressure relief valve 110 fixedly mounted thereon, and a pair of embedded grooves 120 are provided on the side walls of the inner cavity of the through groove 108. The limit ring 140 is installed, and a slider 130 is embedded and slidably installed in the inner cavity of the embedded groove 120. A push rod 150 is fixedly installed on the side wall of the slider 130. The push rod 150 passes through and is slidably installed in the inner ring of the limit ring 140. The side wall of the slider 130 and the side wall of the limit ring 140 are elastically connected by a spring three 160. The push rod 150 is fixedly installed on the end away from the slider 130. A circular plate 170 is fixedly installed. A limit rod 190 is rotatably sleeved on the circumferential outer wall of the push rod 150. The limit rod 190 and the circular plate 170 are elastically connected by a torsion spring two 180. A shift rod 200 is fixedly installed on one end of the rotating shaft 103, and a positioning plate 210 is fixedly installed on the circumferential side wall of the circular plate 170. The positioning plate 210 is used to limit the flipping angle of the limit rod 190, and a limiting relationship can be formed between the limit rod 190 and the shift rod 200, such as Figure 13 As shown, the limiting rod 190 and the shifting rod 200 are both configured with arc surfaces.

[0042] Specifically, if Figure 1-Figure 3 As shown, during the snow removal process, if a relatively solid snow block is encountered, the interaction force between the bristles 78 and the snow increases again. When the controller (not shown) determines that the value of the pressure sensor 40 increases again, the electronic valve 1 20 is in the open state, and the electronic valve 2 30 is in the open state. The compressed gas will enter the air inlet chamber 2 45 through the electronic valve 2 30, as shown in FIG. Figure 5-Figure 6As shown, the electronic gas valve 3 109 is opened and the pressure relief valve 110 is closed. The compressed gas enters the through groove 108 through the electronic gas valve 3 109 and pushes the push rod 150 to slide inside the through groove 108 through the slider 130, and puts the spring 3 160 into a compressed state. During the movement of the push rod 150, the limit rod 190 is simultaneously driven to move. When the push rod 150 slides to the maximum movement distance, the limit rod 190 is disengaged from the lever 200, so that the restriction relationship between the limit rod 190 and the lever 200 is released. At this time, due to the high-speed rotation of the roller 4, under the action of centrifugal force, the breaker hammer 107 will be thrown outward away from the roller 4, and the traction rope 106 drives the rotating shaft 103 to rotate and puts the torsion spring 105 into a charged state. When the breaker hammer 107 reaches the maximum extension distance, it rotates synchronously with the roller 4 at a high speed. During the high-speed rotation, the breaker hammer 107 breaks the relatively solid snow blocks, and then cooperates with the cleaning component 7 to achieve a better cleaning effect.

[0043] When the breaker hammer 107 reaches the maximum extension distance, the length is consistent with the length of the bristles 78, which prevents the breaker hammer 107 from directly hammering on the ground, avoiding damage to the breaker hammer 107 or damage to the road surface.

[0044] When the crushing is completed, the rotation speed of the motor 32 and the roller 4 is reduced to reduce the centrifugal force on the breaker hammer 107, the electronic gas valve 3 109 is closed, and the pressure relief valve 110 is opened to release the compressed gas. Under the elastic force of the spring 3 160, the slider 130 drives the limit rod 190 to reset through the push rod 150. Since the torsion force of the torsion spring 105 is greater than the centrifugal force on the breaker hammer 107 at this time, the traction rope 106 is reeled through the rotating shaft 103 under the torsion force of the torsion spring 105, and the breaker hammer 107 is reeled back to its original position. During the reeling process, since the limit rod 190 and the dial rod 200 are both arranged with an arc surface, and since the limit rod 190 It can rotate on the top rod 150. When the arc surface of the driving rod 200 contacts the arc surface of the limiting rod 190, it will drive the limiting rod 190 to rotate clockwise on the top rod 150. When the driving rod 200 passes the limiting rod 190, under the torsion force of the torsion spring 2 180, the limiting rod 190 rotates and resets. When it rotates to its original position, it will be blocked by the positioning plate 210. This cycle repeats. When the breaker hammer 107 is completely reset, the limiting rod 190 forms a snap-fit ​​relationship with the driving rod 200, and the limiting rod 190 is blocked by the positioning plate 210, which is used to prevent the breaker hammer 107 from being thrown out again when the roller 4 resumes high-speed rotation, thereby avoiding damage to the breaker hammer 107 or damage to the road surface.

[0045] Through the above settings, when encountering relatively solid snow blocks, compressed gas can be used to release the restrictions of the crushing component 10, and then the crushing hammer 107 can be driven out by the cooperation of centrifugal force, and the crushing hammer 107 is used to crush the relatively solid snow blocks, and then cooperate with the multi-directional composite force generated by the bristles 78 on the snow blocks, which can significantly improve the snow removal effect.

[0046] In order to solve the technical problem that the roller brush cannot accurately fill the random and irregular concave areas when it is lowered as a whole or in sections, which affects the snow removal effect, such as Figure 7-10 As shown, the following preferred technical solutions are provided: like Figure 7 and Figure 9-10 As shown, the adjustment assembly 8 includes a push plate 81 slidably mounted in the slide groove 46, as shown in FIG. Figure 3 As shown, the push plate 81 is arranged in the inner cavity of the air inlet chamber 44, and a plurality of mounting ears 82 are fixedly installed on the circumferential outer wall of the push plate 81. The mounting ears 82 and the mounting ears 79 are movably connected through a connecting rod 83. A pair of permanent magnets 84 are fixedly installed on the side walls of the push plate 81, and electromagnets 85 are fixedly installed on the side walls of the inner cavities of the two slide grooves 46, respectively. The electromagnets 85 and the permanent magnets 84 are aligned.

[0047] Specifically, during the snow removal process, the electromagnet 85 generates a repulsive force on the permanent magnet 84. Under the action of the repulsive force and the elastic force of the spring 9, the push plate 81 will not slide in the slide groove 46, thereby preventing the cleaning component 7 from extending outward when the snow is removed on a flat road surface. When random, irregular concave areas appear on the road surface, such as Figure 3 As shown, when the electronic gas valve 20 is opened, the compressed gas will enter the inner cavity of the air inlet chamber 44 through the electronic gas valve 20. At this time, increasing the opening of the electronic gas valve 20 and increasing the air intake volume can not only improve the rotation speed of the bristles 78, but also offset a part of the elastic force of the spring 9. When the electromagnet 85 is used to generate attraction to the permanent magnet 84, electric energy can be saved. When the electromagnet 85 generates attraction to the permanent magnet 84, the push plate 81 can slide in the slide groove 46. During the sliding process, the connecting rod 83 and the mounting ear 79 are used to push the slide 71 to slide inside the limit groove 622, so that the slide 71 drives the rotating drum 74 and The bristles 78 extend in the direction away from the roller 4, and the extension length of the bristles 78 is adjusted by the moving distance of the push plate 81 to match random and irregular recessed areas, and the bristles 78 on each annular mounting seat 6 can be adjusted independently. Compared with the traditional segmented adjustment or overall adjustment, it has a good snow removal effect, and this method is a dynamic adjustment, which can adapt to the road surface of different recessed areas in real time and has good flexibility. In addition, it also avoids the situation where when a part of the roller brush touches the bottom surface of the recessed area, the roller brushes in other areas will exert greater pressure on the surrounding ground, causing damage to the road surface or aggravating the wear of the roller brush.

[0048] To better illustrate the above embodiment, the present invention also proposes another embodiment: a snow removal method for a pure electric snow removal vehicle, the specific steps of which are as follows: Step 1: Fix the snow removal roller brush to the pure electric snow removal vehicle through the mounting bracket 2, electrically connect the power connector on the snow removal roller brush to the power supply on the pure electric snow removal vehicle so that the power assembly 3 and the pressure sensor 40 can be powered normally, and then connect the rotary joint 5 to the air compressor on the pure electric snow removal vehicle through the air pipe; Step 2: The power assembly 3 drives the roller 4, the annular mounting seat 6 and the cleaning assembly 7 to rotate at high speed to clean the snow on the road; Step 3: During the snow removal process, different snow accumulation states are determined by the pressure sensor 40; Step 4: Enable different snow removal modes according to different snow accumulation conditions.
