Description

Technical Field

[0001] The invention relates to the field of snow melting and spreading devices, in particular to a snow melting and spreading device for roads. Background Art

[0002] The snow-melting spreading device is used to spread snow-melting agents including chloride salt components on the road surface to lower the melting point of ice and snow. It can effectively remove ice and snow from the road, improve road safety conditions, and improve road transportation efficiency.

[0003] However, during the snow-melting and spreading process, the snow-melting agent will accelerate the crystallization of salt and cause agglomeration after coming into contact with the air. This will make it difficult for the snow-melting agent to be discharged from the discharge port or even block the discharge port. After the snow-melting and spreading device has been shut down for a certain period of time, its discharge port is also easily blocked by the snow-melting agent and cannot be discharged. It needs to be manually cleaned before continuing to work. All of these will affect the effect and efficiency of the snow-melting and spreading work.

[0019] The beneficial effects of the present invention are:

[0020] 1. Through the arrangement of the blocking mechanism and several pushing members, when the rotating member rotates to the point where several pushing members push open the blocking part, several feeding gaps for feeding are formed between the rotating member and the blocking part. When the snowmelt spreading device spreads the snowmelt agent, its feeding gap is continuously opened and closed with the rotation of the rotating member, and the pushing member can crush the snowmelt agent entering the feeding gap to a certain extent as the rotating member rotates, thereby avoiding the situation where the installation port is blocked by the snowmelt agent and the feeding gap cannot be fed, and even if the snowmelt spreading device is stopped for a certain period of time and its installation port is blocked by the snowmelt agent, the snowmelt agent agglomerated in the installation port and between the rotating member and the blocking plate can be crushed under the rotation and pushing action of the several pushing members driven by the rotating member, and the feeding and spreading work can be continued, thereby ensuring the spreading efficiency and restart speed of the snowmelt spreading device and the spreading effect. On this basis, through the setting of the sealing mechanism, when the rotating part rotates to the top of the sealing part on a number of pushing parts, the snow-melting agent will move toward the blocking part on one side along with the rotational force of the rotating part, and will not easily leak out from the gap between the sealing part and the rotating part, so as to ensure that the snow-melting agent can be discharged stably through the discharge gap, ensure the feasibility and stability of the cooperation between the rotating part and the blocking part, and improve the discharge stability of the snow-melting spreading device.

[0021] 2. By adding an adjustment mechanism and a plurality of first springs, the inner swing angle of the lower end of the first pressure plate can be adjusted by rotating the adjustment member to adjust the tightness of the pressing fit of the material blocking portion, and then the deformation degree of the material blocking portion when the plurality of pushing members push the material blocking portion open, so as to adjust the width of the material discharge gap formed between the rotating member and the material blocking portion, thereby realizing the adjustment of the material discharge amount, so that the snow melting spreading device can adapt to different road surfaces and different snow accumulation levels to adjust the spreading amount of the snow melting agent, thereby improving the adaptability of the snow melting spreading device.

[0022] 3. By adding the first connecting rod, the second connecting rod and the third connecting rod, before the snow melting and spreading work, the first connecting rod can be manually pulled to adjust the width of the feeding gap, and then the corresponding positioning hole can be sleeved onto the positioning pin shaft and the latch can be inserted to lock it. Therefore, under the premise of achieving adjustable feeding gap width, the adjustment drive cost is reduced, and the overall manufacturing cost and working cost of the snow melting and spreading device are reduced.

[0023] 4. When the rotating part drives several pushing parts to rotate, several rows of pushing parts alternately squeeze and crush the snow-melting agent that falls to the top of the rotating part and in the gap between the materials, thereby improving the crushing effect, further avoiding the situation where the snow-melting agent agglomerates and the materials are not effectively discharged, and further ensuring the stability of the materials.

[0024] 5. The agglomerated snow-melting agent in the receiving chamber is stirred and broken by the stirring action of a plurality of first stirring plates and second stirring plates, and the adjacent first stirring plates and second stirring plates with opposite inclination angles can stir and squeeze the snow-melting agent in the receiving chamber to improve the stirring and breaking effect.

[0025] 6. By adding an eccentric mechanism, after the snow-melting spreading device has been working for a certain period of time and a certain amount of agglomerated snow-melting agent has accumulated in the installation port, the two ends of the driven shaft can be locked through the locking mechanism to rotate the rotating part and drive the driven shaft and the eccentric wheel to rotate to generate an eccentric force, so as to drive the rotating part to vibrate, thereby breaking up the agglomerated snow-melting agent gathered at the installation port and the top of the rotating part through the rotational force of the rotating part, avoiding the agglomerated snow-melting agent from being blocked at the installation port, so that the loose snow-melting agent is difficult to discharge through the discharge gap, resulting in unstable discharge. It can also avoid the situation where too much agglomerated snow-melting agent accumulates at the installation port and blocks the installation port, resulting in the inability to discharge the material in the discharge gap, further ensuring the discharge stability and spreading effect of the snow-melting spreading device when it works for a long time.

[0026] 7. When it is necessary to vibrate the material through the rotating part, the two ends of the driven shaft can be quickly locked by the magnetic attraction of the electromagnets on the locking columns. When the vibration of the rotating part is not required, the electromagnets can be powered off to lose the magnetic attraction and the elastic force of the third springs can be used to quickly reset and unlock the locking and unlocking efficiencies of the locking mechanism. At the same time, the electromagnet only needs to be energized when the locking mechanism is locked, and the vibration time of the rotating part only takes a few minutes. The electromagnet does not need to be energized when the locking mechanism is unlocked. Therefore, the power consumption of the locking mechanism can be greatly saved, the power cost of the snow melting and spreading device can be reduced, and the overall snow melting and spreading work cost can be reduced.

[0027] 8. By adding a vibrating mechanism, when discharging materials in the discharging gap, the loose snow-melting agent can be directly discharged through the screening gap between the several vibrating parts, and the agglomerated snow-melting agent can be blocked on the top of the several vibrating parts, so that the snow-melting agent discharged to the installation port and the top of the rotating part is screened and sorted before vibrating. On this basis, when the rotating part vibrates, the several vibrating parts are driven to vibrate through the sealing part, so that the several vibrating parts can directly break up the agglomerated snow-melting agent screened out and gathered on the top, so that the vibration force of the rotating part is directly transmitted to the screened agglomerated snow-melting agent through the sealing part and the vibrating part in turn, and will not be blocked and consumed and weakened by the loose snow-melting agent accumulated on the top of the rotating part. Through the cooperation of the vibration of the vibrating mechanism and the rotating part, the specificity of vibrating the agglomerated snow-melting agent is improved, and the vibration effect and efficiency are improved.

[0037] Embodiment 1

[0038] Reference Figure 1-5 As shown, a snow melting and spreading device for roads comprises:

[0039] A hopper 1 is provided with a mounting opening 12 at the bottom, and a receiving chamber 11 is provided inside the hopper 1; the hopper 1 is used to be hung and installed on a corresponding loading vehicle, and the receiving chamber 11 is used to receive a snow-melting agent;

[0040] The rotating member 2 rotates corresponding to the inner side of the installation opening 12 and is driven to rotate by the rotation driving device 3. The outer wall protrusion of the rotating member 2 is provided with a plurality of thrust members 21 arranged at intervals;

[0041] The material blocking mechanism 4 comprises a material blocking member 41 which is clamped by a first pressure plate 42 on the outer wall of one side of the hopper 1 and corresponds to the side of the mounting opening 12, the lower end of the material blocking member 41 protrudes from the first pressure plate 42 to form a material blocking portion 411 which flexibly abuts against the outer wall of the rotating member 2; specifically, the upper end of the material blocking portion 411 abuts against the outer wall of the rotating member 2, and the lower end extends in a direction away from the rotating member 2, and the material blocking member 41 is made of an elastic material such as rubber;

[0042] The blocking mechanism 5 comprises a blocking member 51 which is clamped by a second pressure plate 52 on the outer wall of the other side of the hopper 1 and corresponds to the other side of the installation opening 12. The blocking member 51 extends inward and flexibly abuts against the top of the rotating member 2. When the rotating member 2 rotates until the pushing members 21 push the blocking portion 411 away, a plurality of material discharge gaps for material discharge are formed between the rotating member 2 and the blocking portion 411. Specifically, the blocking member 51 is made of an elastic material such as rubber.

[0043] The above structure is provided with the blocking mechanism 4 and the plurality of pushing members 21, so that when the rotating member 2 rotates until the plurality of pushing members 21 push the blocking portion 411, a plurality of feeding gaps for feeding are formed between the rotating member 2 and the blocking portion 411. When the snowmelt spreading device spreads the snowmelt agent, the feeding gap is continuously opened and closed with the rotation of the rotating member 2, and the pushing members 21 can crush the snowmelt agent entering the feeding gap to a certain extent with the rotation of the rotating member 2, thereby avoiding the situation that the installation port 12 is blocked by the snowmelt agent and the feeding gap cannot be fed, and even when the snowmelt spreading device is stopped for a certain period of time and the installation port 12 is blocked by the snowmelt agent, the snowmelt agent agglomerated in the installation port 12 and between the rotating member 2 and the blocking plate can be crushed under the rotation and pushing action of the plurality of pushing members 21 driven by the rotating member 2, and the feeding and spreading work can be continued, thereby ensuring the spreading efficiency and restart speed of the snowmelt spreading device and the spreading effect. On this basis, through the setting of the sealing mechanism 5, when the rotating part 2 rotates to the plurality of pushing parts 21 to push the sealing part 51, the snow-melting agent will move toward the blocking part 41 on one side along with the rotational force of the rotating part 2, and will not easily leak out from the gap between the sealing part 51 and the rotating part 2, so as to ensure that the snow-melting agent can be stably discharged through the discharge gap, ensure the feasibility and stability of the cooperation between the rotating part 2 and the blocking part 41, and improve the discharge stability of the snow-melting spreading device.

[0044] In order to improve the adaptability of the snow melting and spreading device, it also includes an adjusting mechanism 6, which includes an adjusting member 61 whose lower end is inserted between the upper end of the first pressure plate 42 and the outer wall of one side of the hopper 1, an adjusting shaft 62 that is vertically rotatable and arranged outside one side of the hopper 1 and connected to the adjusting member 61, and an adjusting driving component for driving the adjusting shaft 62 to rotate inward or outward. The material blocking mechanism 4 also includes a plurality of screwed members 43 that are screwed through the middle of the hopper 1 and the first pressure plate 42 and are distributed laterally at intervals, respectively limiting A plurality of screw sleeves 44 are screwed to the inner and outer ends of a plurality of the screw connectors 43, and a first spring 45 is respectively sleeved on the plurality of the screw connectors 43 and is topped between the outer wall of the hopper 1 and the outer end of the screw sleeve 44. Specifically, the screw connector 43 is a bolt, and the screw sleeve 44 is a nut. After the two adjusting shafts 62 rotate inwardly, the lower end of one side of the adjusting member 61 rotates outwardly and pushes the upper end of the first pressure plate 42 outward, so that the lower end of the first pressure plate 42 swings inwardly under the elastic force of the plurality of the first springs 45 to press the material blocking portion 411. Therefore, by adding the adjustment mechanism 6 and a plurality of first springs 45, the inner swing angle of the lower end of the first pressure plate 42 can be adjusted by rotating the adjustment member 61 to adjust the tightness of the pressing fit of the first pressure plate 42 on the material blocking portion 411, and then the deformation degree of the material blocking portion 411 when the plurality of pushing members 21 push the material blocking portion 411 open, so as to adjust the width of the material discharge gap formed between the rotating member 2 and the material blocking portion 411, thereby realizing the adjustment of the material discharge amount, so that the snow melting spreading device can adapt to different road surfaces and different snow accumulation levels to adjust the spreading amount of the snow melting agent, thereby improving the adaptability of the snow melting spreading device.

[0045] In order to save costs, the adjustment drive assembly includes a first connecting rod 63, a second connecting rod 64, and a third connecting rod 65 which are rotatably connected in sequence. The first connecting rod 63 is linked to the adjustment shaft 62. The third connecting rod 65 is located on the upper side of the first connecting rod 63 and is penetrated by a plurality of positioning holes 651 distributed along the axial direction. The outer wall of the hopper 1 is provided with a positioning pin shaft 13 corresponding to the positioning hole 651. A second spring 66 is connected between the end of the first connecting rod 63 away from the second connecting rod 64 and the middle part of the second connecting rod 64. The adjustment member 61 is set to be U-shaped with the opening facing downward and a fixed cover is set on the outer wall of the adjustment shaft 62. Therefore, by adding the first connecting rod 63, the second connecting rod 64 and the third connecting rod 65, before the snow melting and spreading work is carried out, the first connecting rod 63 is manually pulled to adjust the width of the feeding gap, and then the corresponding positioning hole 651 is sleeved on the positioning pin shaft 13 and the latch is inserted to lock it. This reduces the adjustment drive cost while achieving the adjustable feeding gap width, and reduces the overall manufacturing cost and working cost of the snow melting and spreading device.

[0046] In order to improve the crushing effect of the pushing members 21 on the snow-melting agent falling to the top of the rotating member 2 and the feeding gap, a plurality of the pushing members 21 are arranged in a circular array on the outer wall of the rotating member 2, and the pushing members 21 in adjacent rows are arranged alternately. Therefore, when the rotating member 2 drives the plurality of pushing members 21 to rotate, the plurality of rows of pushing members 21 are alternately squeezed and crushed on the snow-melting agent falling to the top of the rotating member 2 and the feeding gap, thereby improving the crushing effect, further avoiding the situation where the snow-melting agent agglomerates and the feeding is ineffective, and further ensuring the feeding stability.

[0047] In order to reduce the probability of agglomeration of the snowmelt in the receiving chamber 11, a stirring rod 14 extending left and right and driven to rotate by the rotary drive device 3 is provided in the receiving chamber 11, and a plurality of first stirring plates 15 with the left end higher than the right end and a plurality of second stirring plates 16 with the left end lower than the right end are fixedly provided on the outer walls of both sides of the stirring rod 14, and the plurality of the first stirring plates 15 and the plurality of the second stirring plates 16 on the same side are staggered and distributed in a horizontally staggered manner, and the plurality of the first stirring plates 15 and the plurality of the second stirring plates 16 on both sides are staggered and distributed in a horizontally staggered manner. Thus, the agglomerated snowmelt in the receiving chamber 11 is stirred and broken by the stirring action of the plurality of first stirring plates 15 and the second stirring plates 16, and the adjacent first stirring plates 15 and the second stirring plates 16 with opposite inclination angles can stir and squeeze the snowmelt in the receiving chamber 11 to improve the stirring and breaking effect.

[0048] Embodiment 2

[0049] refer to Figure 5-9 The difference between this embodiment and the first embodiment is that:

[0050] In order to further reduce the risk of agglomerated snow-melting agent blocking the installation port 12 and the material discharge gap, the rotating member 2 is configured as a roller, and a rotating seat 22 is fixedly arranged at both ends of the roller to rotate with the hopper 1. The rotating drive device 3 drives the rotating seat 22 to rotate through a sprocket and a chain. An eccentric mechanism 7 is provided in the rotating member 2, and the eccentric mechanism 7 includes a driven rotating shaft 71 rotatably connected to the two rotating seats 22 at both ends through bearings 711, and an eccentric wheel 72 fixedly sleeved on the driven rotating shaft 71 and spaced apart from the two rotating seats 22 The rotating member 2 is also provided with a locking mechanism 8 for locking the two rotating seats 22 and the two ends of the driven shaft 71; when the locking mechanism 8 locks the two ends of the driven shaft 71, the rotating member 2 rotates and drives the driven shaft 71 and the eccentric wheel 72 to rotate to generate an eccentric force, so as to drive the rotating member 2 to vibrate, thereby vibrating the snow-melting agent on the top of the rotating member 2. In actual use, the rotation of the rotary drive device 3 can be increased to increase the vibration frequency to improve the vibration effect, and the vibration time only needs a few minutes.

[0051] The arrangement of the above structure, through the addition of the eccentric mechanism 7, allows the locking mechanism 8 to lock the two ends of the driven shaft 71 after the snow-melting spreading device has been working for a certain period of time and a certain amount of agglomerated snow-melting agent has accumulated in the installation port 12, so that the rotating member 2 can rotate and drive the driven shaft 71 and the eccentric wheel 72 to rotate to generate an eccentric force, thereby driving the rotating member 2 to vibrate, thereby shattering the agglomerated snow-melting agent gathered at the installation port 12 and the top of the rotating member 2 through the rotational force of the rotating member 2, thereby avoiding the agglomerated snow-melting agent from being blocked in the installation port 12, so that the loose snow-melting agent is difficult to be discharged through the feeding gap, resulting in unstable feeding. It can also avoid the situation where too much agglomerated snow-melting agent accumulates in the installation port 12 and blocks the installation port 12, resulting in the inability to discharge the feeding gap, further ensuring the feeding stability and spreading effect of the snow-melting spreading device when it works for a long time.

[0052] In order to improve the locking efficiency and unlocking efficiency of the locking mechanism 8, the opposite sides of the two rotating seats 22 are recessed with rotating grooves 221, and the two ends of the driven shaft 71 are rotatably inserted in the rotating grooves 221 through bearings 711. The side walls of the two ends of the driven shaft 71 are recessed with a plurality of limiting grooves 712 at circumferential intervals, and the inner wall recess of the rotating groove 221 is provided with a plurality of positioning grooves 222 corresponding to the limiting grooves 712. The locking mechanism 8 includes a plurality of locking columns 81 adapted to be slidably arranged in the plurality of limiting grooves 712, and a plurality of locking columns 81 connected to the plurality of locking columns 81. 81 and a plurality of third springs 82 of the limiting groove 712, and a plurality of electromagnets 83 arranged on the inner wall of the rotating seat 22 and corresponding to the bottom of the plurality of said positioning grooves 222; when the plurality of said electromagnets 83 are energized, the plurality of said locking columns 81 are magnetically attracted to be locked to the plurality of said positioning grooves 222 and circumferentially lock the plurality of said positioning grooves 222 and the limiting grooves 712, and then lock the driven rotating shaft 71 and the rotating seat 22; when the plurality of said electromagnets 83 are de-energized, the plurality of said locking columns 81 are reset by the pulling force of the plurality of said third springs 82 and are disengaged from the plurality of said positioning grooves 222 and are unlocked. Therefore, when it is necessary to vibrate the crushed materials through the rotating part 2, the two ends of the driven rotating shaft 71 can be quickly locked through the magnetic attraction of the locking columns 81 by the multiple electromagnets 83. When the vibration of the rotating part 2 is not needed, the multiple electromagnets 83 can be powered off to lose the magnetic attraction and the elastic force of the multiple third springs 82 can be used to quickly reset and unlock the multiple locking columns 81, so as to improve the locking efficiency and unlocking efficiency of the locking mechanism 8. At the same time, the electromagnet 83 only needs to be energized when the locking mechanism 8 is locked, and the vibration time of the rotating part 2 only takes a few minutes. The electromagnet 83 does not need to be energized when the locking mechanism 8 is unlocked. Therefore, the power consumption of the locking mechanism 8 can be greatly saved, the power cost of the snow melting and spreading device can be reduced, and the overall snow melting and spreading work cost can be reduced.

[0053] Since a large amount of loose snow-melting agent and agglomerated snow-melting agent will be mixed and accumulated on the top of the rotating member 2, the vibration effect of the rotating member 2 will be blocked and consumed by the loose snow-melting agent and weakened, making it difficult to act on the agglomerated snow-melting agent in a targeted manner. Therefore, in order to improve the vibration effect and vibration efficiency, a vibration mechanism 9 is provided in the accommodating chamber 11, and the vibration mechanism 9 includes a plurality of rigid vibration members 91 distributed along the axial direction of the rotating member 2 at intervals, one end of the plurality of vibration members 91 is inserted and fixed in the sealing member 51, and the other end forms a vibration part 911 extending to the gap with the blocking member 41, the vibration part 911 is spaced above the rotating member 2, and the gap between the plurality of vibration parts 911 is set to form a screening gap 92, specifically, the two ends of the plurality of vibration members 91 are rounded; thereby, by adding the vibration mechanism 9, when discharging materials in the discharging gap, The screening gaps 92 between the vibrating parts 911 allow the loose snow-melting agent to be directly discharged and the agglomerated snow-melting agent to be blocked at the tops of the vibrating parts 911, so that the snow-melting agent discharged to the installation port 12 and the top of the rotating part 2 is screened and sorted before vibration. On this basis, when the rotating part 2 vibrates, the sealing part 51 drives the vibrating parts 91 to vibrate, so that the vibrating parts 911 can directly break up the agglomerated snow-melting agent screened out and gathered on the top, so that the vibration force of the rotating part 2 is directly transmitted to the screened agglomerated snow-melting agent through the sealing part 51 and the vibrating part 91 in turn, and will not be weakened by the blocking and consumption of the loose snow-melting agent accumulated on the top of the rotating part 2. Through the coordination of the vibration of the vibrating mechanism 9 and the rotating part 2, the specificity of the vibration of the agglomerated snow-melting agent is improved, and the vibration effect and efficiency are improved.

[0054] It should be pointed out that the implementation principle and technical effects of this embodiment are the same as those of Embodiment 1. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in Embodiment 1.
