Description

Technical Field

[0001] The utility model relates to the field of road anti-skid, in particular to an under-vehicle throwing machine. Background Art

[0002] Vehicles rely on the friction between the wheels and the ground to travel on the road. When there is heavy snowfall in winter, snow will accumulate on the highway. If there are still vehicles on the road and they are not driven away in time, it is very easy for vehicles to slip and break down, causing accidents and large-scale congestion on the highway. At this time, because the vehicles are parked on the highway, the snow under the vehicles cannot be cleared quickly, and snowplows cannot be used, making it difficult to clear traffic.

[0003] In the prior art, some adopt the solution of laying anti-skid materials on the road surface. After the wheels roll over the anti-skid materials, the friction coefficient between the wheels and the slippery ground increases, so that the vehicle can drive smoothly. However, when the road surface is already blocked over a large area, it is difficult to effectively lay anti-skid materials under the vehicles parked side by side on a wider road surface, so the implementation of this technical solution has certain difficulties.

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] Figure 1 is a schematic diagram of the overall structure of an under-vehicle throwing machine provided by an embodiment of the present utility model, Figure 2 is a side view of an under-vehicle throwing machine provided by an embodiment of the present utility model.

[0036] As Figure 1 shown in Figure 2 the under-vehicle throwing machine provided by the embodiment of the present utility model includes a traveling component 1 and a throwing component 2. The traveling component 1 can drive the throwing component 2 to travel along the road surface. The throwing component 2 includes a discharge housing 22. An accommodation space is provided in the discharge housing 22, and the accommodation space is communicated with the material to be thrown. A rotating member is provided in the accommodation space. The rotating member includes a rotating shaft and blades 221 installed on the rotating shaft. A discharge port 222 is provided on one side of the discharge housing 22 close to the bearing surface, and the direction of the discharge port 222 is parallel to the tangent of the outer edge of the blade 221 on the side close to the bearing surface during rotation.

[0037] After introducing the material to be thrown in the discharge housing 22, the rotation of the blade 221 causes the material to be thrown to rotate synchronously in the accommodation space, so that the material to be thrown is subjected to a centrifugal force, which accelerates the material to be thrown and then sprinkles it outside the discharge housing through the discharge port; since the discharge port is located on the side of the discharge housing close to the ground, and the direction of the discharge port is parallel to the rotation tangent direction, where the rotation tangent direction is the tangent on the rotation circumference of the rotating part close to the ground side, therefore, the discharge direction of the discharge port is close to the ground and tends to be parallel to the ground, and can sprinkle materials such as snow melting agents or anti-slip agents in the gap between the vehicle chassis and the ground, so that the anti-slip material can be smoothly laid on the entire road surface. When the wheel contacts the anti-slip material, the friction coefficient between it and the ground becomes larger, so that the vehicle can drive smoothly on the snow.

[0038] Among them, the material to be thrown can be a flower fertilizer-like biomass anti-slip material, such as crushed straw or grass stalks, etc. Such materials can be rapidly degraded in the natural environment. While achieving the effect of increasing the friction coefficient between the wheel and the ground, they will not pollute the environment and are suitable for large-scale promotion and use.

[0039] Figure 3 It is a schematic structural diagram of the throwing component of the under-vehicle throwing machine provided by an embodiment of the present invention. Figure 5 It is a schematic structural diagram of the discharge housing of the under-vehicle throwing machine provided by an embodiment of the present invention.

[0040] As Figure 3 shown in Figure 5 the figure, a blade 221 is installed in the discharge housing 22, and a discharge port 222 is opened on one side of the discharge housing. When the blade 221 rotates, the anti-slip material in the discharge housing is ejected from the discharge port 222 under the action of the blade 221.

[0041] Furthermore, the throwing component 2 further includes a discharge adjustment mechanism. The discharge port is movably arranged on the discharge housing, and the discharge adjustment mechanism can drive the movement of the discharge port to adjust the angle between the discharge port and the road surface.

[0042] It should be understood that the above discharge port can be rotatably arranged on the discharge housing, and the angle between the discharge port and the road surface can be adjusted by driving the discharge port to rotate through the discharge adjustment mechanism. It can also be arranged on the discharge housing through a linear movement mechanism, and the angle between the discharge port and the road surface can be adjusted by driving the discharge port to move in the vertical direction through the discharge adjustment mechanism. As long as it is an adjustment method that can meet the use requirements, it belongs to the protection scope of this application.

[0043] Specifically, the discharge adjustment mechanism can be a telescopic cylinder arranged at the bottom of the discharge port. The bottom reference end of the telescopic cylinder is fixedly installed at the bottom of the discharge housing 2, and the output end of the telescopic cylinder is installed at the discharge port 222. The discharge height of the discharge port 222 can be adjusted by the expansion and contraction of the telescopic cylinder; or the discharge port 222 can be rotatably arranged on the discharge housing 22, and the discharge adjustment mechanism can adjust and lock the angle between the discharge port 222 and the discharge housing 22 to change the discharge orientation of the discharge port 222.

[0044] By adjusting the discharge height or discharge orientation of the discharge port 222, when the distance and angle between the orientation of the discharge port 222 and the bearing surface are relatively small, the anti-slip material can be ejected at a lower position along a direction parallel to the bearing surface. At this time, the ejection angle and height of the anti-slip material are relatively low, enabling the anti-slip material to smoothly enter the bottom of the road vehicle. Therefore, even when the road vehicle is already congested, the anti-slip material can be laid on the road surface under the vehicle; or the height and orientation of the discharge port 222 can be adjusted according to the actual situation to enable the anti-slip material to be ejected to a farther position, improving the flexibility of use.

[0045] As Figure 5 shown, in one preferred embodiment, the discharge port 222 is connected to the discharge housing through a discharge adjustment mechanism. The discharge adjustment mechanism includes an arc-shaped rack 2221 installed on the discharge port 222 and a gear 223 installed on the discharge housing. The arc-shaped rack 2221 meshes with the gear 223. By rotating the gear 223, the arc-shaped rack 2221 is driven to rotate, and then the discharge port 222 is driven to rotate to adjust the orientation of the discharge port 222. A locking screw 2231 is also provided on one side of the gear 223. After the discharge port 222 is adjusted by the gear 223, the gear 223 is locked by the locking screw 2231, which can limit the rotation of the gear 223 and then lock the discharge port 222 at a certain angle.

[0046] It should be understood that the discharge adjustment mechanism can be, but is not limited to, the form of cooperation between the above-mentioned arc-shaped rack and gear, and can also be a crank rocker mechanism or a cam drive mechanism and other types of structures. As long as it is a structural form that can adjust the discharge port orientation, it belongs to the protection scope of this application.

[0047] Figure 2 is a side view of the under-vehicle throwing machine provided by an embodiment of the present invention, Figure 4 is a rear view of the throwing component of the under-vehicle throwing machine provided by an embodiment of the present invention.

[0048] As Figure 2 With Figure 4As shown, in one preferred embodiment, the under-vehicle material thrower further includes a drive assembly 3. The drive assembly 3 includes an engine, a first rotation unit 31, and a second transmission unit 32. Among them, the first transmission unit 31 is used to transmit the power of the engine to the traveling assembly 1, and the second transmission unit 32 is used to transmit the power of the engine to the rotating member. A transmission state controller can also be installed between the second transmission unit 32 and the rotating member. There are a transmission state and a transmission release state between the second transmission unit 32 and the rotating member. The transmission state controller is used to control the switching between the transmission state and the transmission release state of the second transmission unit 32 and the rotating member.

[0049] As Figure 4 shown, in one preferred embodiment, a belt pulley 23 is installed on the rotating shaft of the rotating member. The second transmission unit 32 is connected to the belt pulley 23 through a belt 321. A pressing belt rod 24 is rotatably arranged on the discharge housing 22. One end of the pressing belt rod 24 is connected to the discharge housing, and the other end contacts the belt 321. An elastic element 241 is installed on one side of the end that contacts the belt 321. A buckle that can be detachably connected to the elastic element 241 is installed on the discharge housing. When the elastic element 241 is connected to the buckle, the pressing belt rod 24 moves in the direction of the buckle, and the part of the pressing belt rod 24 that contacts the belt 321 tensions the belt 321, so that the second transmission unit 32 can output power to the belt pulley 23 and the blade 221. When the elastic element 241 is detached from the buckle, the part of the pressing belt rod 24 that contacts the belt 321 moves away from the belt 321, making the belt 321 in a relaxed state, thereby preventing the blade 221 from rotating with the second transmission unit 32.

[0050] Furthermore, a protruding shaft can be provided at the end of the pressing belt rod 24 that contacts the belt 321, and a rotating part is sleeved on the protruding shaft. By contacting the belt 321 through the rotating part, the frictional resistance of the belt 321 by the pressing belt rod 24 when driving the belt pulley 23 to rotate can be reduced.

[0051] In addition, a driving gear can be installed at the second transmission unit 32, and a driven gear is installed outside the rotating shaft. The transmission state controller is a transmission gear that can be movably arranged on the throwing housing 22. A chute is provided on the throwing housing 22, and the outer circumferential surface of the rotating shaft of the transmission gear can slide in the chute, so that the transmission gear is in a transmission state of simultaneously meshing with the driving gear and the driven gear, and a release state of not simultaneously meshing with the driving gear and the driven gear.

[0052] In one preferred embodiment, the throwing assembly 2 further includes a feeding container 21. A feeding cavity capable of storing the material to be thrown is provided in the feeding container 21. The feeding container 21 and the discharge housing are arranged in sequence from top to bottom, so that the material in the feeding cavity can automatically enter the accommodating space under the action of gravity.

[0053] In one preferred embodiment, a throwing amount adjusting mechanism is provided at the bottom of the feeding container 21. The throwing amount adjusting mechanism includes a flow regulating plate. By adjusting the flow regulating plate, the cross-sectional area of the communication part between the feeding cavity and the accommodating space can be adjusted.

[0054] Among them, the flow regulating plate can be movably arranged at the bottom of the feeding container 21. The throwing amount adjusting mechanism further includes an adjusting driving member for driving the movement of the flow regulating plate. For example, by driving the flow regulating plate to rotate or expand and contract through the adjusting driving member, the cross-sectional area of the communication part between the feeding cavity and the accommodating space changes, so as to realize the adjustment of the throwing flow rate; or the flow regulating plate is detachably arranged at the bottom of the feeding container 21. By adjusting the installation position of the flow regulating plate at the bottom of the feeding container 21, the cross-sectional area of the communication part between the feeding cavity and the accommodating space can be adjusted, and then the throwing flow rate of the throwing assembly 2 can be adjusted. In short, as long as the flow regulating plate can realize the adjustment of the cross-sectional area of the communication part between the feeding cavity and the accommodating space.

[0055] By adjusting the throwing flow rate, the average density of the anti-slip material thrown on the ground by the throwing assembly 22 can be changed. Specifically, according to the actual situation, when the snow is thick, the spreading density can be appropriately increased; when the snow is thin, the spreading density can be appropriately reduced, which can reduce the waste of materials and improve the applicability of the device.

[0056] Such as Figure 3 And Figure 6 As shown, in a specific embodiment, the feeding container 21 includes a hopper 211 and a communication port 212. The hopper 211 is communicated with the discharge housing 22 through the communication port 212, and the anti-slip material is stored in the hopper 211. A baffle plate 2121 and an adjusting bolt 2122 are arranged at the connection part between the hopper 211 and the communication port 212. A long slot hole is formed in the baffle plate 2121. The adjusting bolt 2122 passes through the long slot hole and is threadedly connected with a support plate fixedly installed on the hopper 211. When it is necessary to adjust the discharge area of the hopper 211, loosen the adjusting bolt 2122, move the baffle plate 2121 outward or inward along the matching part of the long slot hole and the adjusting bolt 2122, and then tighten the adjusting bolt 2122.

[0057] Furthermore, as Figure 3 And Figure 6As shown, the part where the feeding container 21 communicates with the discharging housing 22 is located on one side of the axial direction of the rotating shaft and on the upper side of the middle part of the discharging housing 22, so as to form a feeding and discharging mode of axial feeding and radial discharging in the discharging housing 22. Among them, the sealing performance of the discharging housing 22 can be appropriately improved, so that when the blade 221 rotates at a high speed, a certain negative pressure is generated in the discharging housing 22, thereby generating a certain suction force on the anti-slip material in the feeding container 21, enabling the anti-slip material to smoothly enter the discharging housing 22 from the bottom of the feeding container 21 and avoiding arching and blocking of the anti-slip material in the feeding container 21.

[0058] In one preferred embodiment, the traveling assembly 1 includes a base 11 and traveling wheels 12. The throwing assembly 2 and the driving assembly 3 are both installed on the base 11. The traveling wheels 12 are connected to the first driving unit 31. A handle 13 is also installed on the base 11, and a control element is installed on the handle 13. The control element is in signal connection with the traveling assembly 1 and the throwing assembly 2. Parameters such as the start-stop and rotation speed of the engine can be controlled through the control element.

[0059] Furthermore, as Figure 1 and Figure 2 shown, a front wheel can also be provided on the side of the discharging housing away from the traveling assembly 1, so that the traveling of the throwing machine is more stable and the use of the device is more flexible and convenient.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that any modification or equivalent replacement of the technical solutions of the present invention does not depart from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
