Description

Technical Field

[0001] The utility model belongs to the technical field of snow-melting medium spreading equipment, and in particular relates to a novel spreading device for snow-melting medium. Background Art

[0002] In highway clearance work, the commonly used snow-melting medium spreading vehicles are mostly used for spreading operations at the rear of the vehicle body. Due to the influence of weather and other factors during operation, the snow-melting medium is prone to blockage, and the driver cannot be informed in time, and it is easy to miss the spread of hundreds of meters or even longer distances on the highway. Vehicles are not allowed to reverse on the highway, so it is necessary to organize other personnel and vehicles to carry out secondary repetitive operations on the corresponding road surface. There are omissions in the clearance work, which prolongs the highway opening period and the spreading efficiency is very limited.

[0003] In order to improve this situation, another vehicle is currently arranged to follow and observe behind the spreading vehicle, so that when there is a leak, they can communicate with each other in time to stop and clear the gap and spread more. However, this method increases the investment of personnel and equipment, bringing more inconvenience to the already heavy highway clearance work, and the time for road traffic will still be delayed.

[0004] The utility model patent with announcement number CN205839676U discloses a vehicle-mounted automatic spreader, which can spread salt or sand on the road to open the road as soon as possible. The auger conveying method can effectively avoid blockage, and the spreading operation is long-lasting and stable, which has certain beneficial effects in many years of practical application. However, this structure requires a substantial modification or even replacement of the existing spreading vehicle, which is costly and not applicable.

[0005] Therefore, it is necessary to design a device that can be adaptively improved on the basis of the existing spreading equipment, which can not only reduce the cost of transformation, but also enable operators to discover and deal with blockage problems in the first place, so as to improve work efficiency and realize the rapid opening of the road. Utility Model Content

[0006] In order to solve the technical problem that the driver cannot be informed in time when the snow-melting medium is blocked and leaked, the utility model provides a new spreading device for snow-melting medium. It can be slightly modified and upgraded on the basis of existing vehicles. Without the need for other personnel and vehicles to follow, only the driver can find and deal with the leak in time, achieve the fastest remedial response, and finally achieve the technical effect of one-time continuous spreading, greatly improving the working efficiency.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A novel spreading device for snow melting medium comprises a spreading turntable drivingly connected to a driving end of a driving component, a top baffle plate is arranged above the spreading turntable, and a channel for the snow melting medium to fall onto the spreading turntable is provided on the top baffle plate;

[0009] Its characteristics are:

[0010] A blocking structure corresponding to the spreading direction of the spreading turntable is provided on one side of the top baffle, and at least one detector for blocking the snow melting medium is provided in the blocking structure, and the detector is electrically connected to the controller.

[0011] As a further technical solution, the blocking structure includes a side baffle connected to one side of the top baffle, the detector is fixed to the side baffle, and the detection plate of the detector faces the spreading direction of the spreading turntable.

[0012] As a further technical solution, the side baffle is slidably connected to the top baffle via a sliding mechanism.

[0013] As a further technical solution, the sliding mechanism includes a track arranged at the outer edge of the top baffle, and a sliding seat arranged on the side baffle and slidably connected to the track.

[0014] As a further technical solution, the rail and the slide seat are positioned and connected to each other via a fixing member.

[0015] As a further technical solution, a heating element is provided on the side of the detection plate away from the spreading direction of the spreading turntable.

[0016] As a further technical solution, a shielding plate for shielding the heating element 1 is provided on the top of the detection plate.

[0017] As a further technical solution, a second heating element is provided on the side baffle.

[0018] As a further technical solution, the outer periphery of the top baffle is a downwardly curved arc structure.

[0019] As a further technical solution, a collector is connected in series between the detector and the controller.

[0020] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0021] During spreading, the snow-melting medium can be thrown out at high speed under the action of centrifugal force, and the detector can block the snow-melting medium. When the snow-melting medium touches the detection plate at high speed, the detection plate will be subjected to a certain pressure and finally make a corresponding output electrical signal through the controller, so that the driver can make a timely judgment. If the snow-melting medium is blocked and cannot be thrown out, the detection plate will not be hit and pressed, and the controller will output another electrical signal to remind.

[0022] After using the utility model, the driver can immediately know whether the snow melting medium is blocked, so as to make corresponding remedial measures, and other personnel and vehicles do not need to follow and accompany. A single shift can fully spread the snow on the road at one time, greatly improving the working efficiency. Moreover, the transformation cost is very low, saving considerable cost investment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Embodiment 1

[0040] See attached Figure 1 To Attachment Figure 8 The embodiment of the utility model provides a new spreading device for snow melting medium, which can be slightly modified on the basis of the existing spreading vehicle structure without the need for overall replacement, which can save considerable modification costs, complete the spreading operation in one go, and improve efficiency. When in use, the device is installed at the rear of the vehicle and connected to the tank on the vehicle bucket through a pipeline, so that the snow melting medium can enter the device conveniently.

[0041] Specifically, it includes a spreading turntable 104 that is transmission-connected to the driving end of the driving component 102, and can realize high-speed rotation of the spreading turntable 104 with the driving end as the center. The driving component 102 is a hydraulic motor, which has the advantages of being stable, reliable and not afraid of rain. If a motor is used, it is easy to be damaged in bad weather. A top baffle 101 is arranged above the spreading turntable 104 to prevent the snow-melting medium from splashing upward. The purpose of the interval is to facilitate the entry of the snow-melting medium and leave sufficient centrifugal space, and the top baffle 101 is provided with a channel 103 for the snow-melting medium to fall onto the spreading turntable 104. When the snow-melting medium falls on the spreading turntable 104, it can be thrown out to the surroundings at high speed under the action of centrifugal force, forming a radial spreading operation on the road. This is a conventional technical means.

[0042] One side of the top baffle 101 in the utility model is provided with a blocking structure that is opposite to the spreading direction of the spreading turntable 104, and the purpose of the setting is to block a part of the snow-melting medium. For example, the snow-melting medium spread toward the bottom of the vehicle is blocked so that it falls vertically downward without affecting the normal spreading effect. The blocking structure is provided with at least one detector 300 for blocking the snow-melting medium. In actual use, three detectors 300 are usually provided. The detector 300 is electrically connected to the controller 5 to timely collect the operating electrical signal of the detector 300 and timely feed it back to the driver for observation and judgment. The detector 300 actually uses a Spato brand large-range pressure sensor (SBT710), which can accurately capture the pressure value.

[0043] In addition, refer to Figure 8 A collector 4 is connected in series between the detector 300 and the controller 5, which can be connected in parallel with multiple detectors 300 to collect detection data from multiple locations, calculate them, and then transmit them to the controller 5 placed in the cab. The data detected by multiple detectors 300 will be more accurate after average calculation, which prevents the difficulty of timely human judgment when only one detector 300 fails, and is more practical.

[0044] The specific principles are explained below:

[0045] When the snowmelt medium is thrown out at high speed, it can touch the detection plate 301 of the detector 300, and the detection plate 301 can transmit the received pressure signal to the controller 5. Specifically, the faster the spreading turntable 104 rotates, the greater the centrifugal force is, the faster the snowmelt medium is thrown out, and the greater the impact force received by the detection plate 301, that is, the greater the pressure received.

[0046] On the contrary, when the pressure value detected by the detector 300 is smaller, and other components are operating normally, it means that the snow melting medium is blocked, that is, the snow melting medium that hits the detector 300 is less. At this time, the controller 5 will generate sound and light alarm signals through the sound output device 51 and the light output device 52, and the driver can find it in time and stop the car for disposal. Of course, the premise is that the spreading turntable 104 is working normally and the detector 300 cannot detect the pressure signal. After getting off the car, the driver can clear the conveying channel by means of a tamping stick or shaking. Although it is manual dredging, it can be found in time without the company of others. Compared with the traditional operation method, the beneficial technical effect is obvious.

[0047] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As a further improvement of this embodiment, the blocking structure includes a side baffle 201 connected to one side of the top baffle 101, which can prevent the snow-melting medium from being scattered to the bottom of the vehicle, so that the snow-melting medium falls vertically and forms more coverage on the driving lane, that is, the amount of snow-melting medium spread is larger and will not be widely spread, and the driving lane can achieve snow melting effect faster. The detector 300 is fixed (such as fastened, clamped or welded) on the side baffle 201, and the detection plate 301 of the detector 300 faces the spreading direction of the spreading turntable 104. The two are preferably in the same horizontal plane and collide at a frontal angle. Of course, a sufficient gap needs to be left between the detection plate 301 and the spreading turntable 104 to allow the snow-melting medium to fall.

[0048] As a further technical solution, the outer periphery of the top baffle 101 is a downward curved arc structure, which facilitates the snow-melting medium to fall at a downward arc angle, thereby facilitating the spreading of more snow-melting medium on a limited road area rather than spreading it over the maximum area. Embodiment 2

[0049] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The purpose of this embodiment is to achieve flexible adjustment of spreading direction and spreading area to adapt to different roads.

[0050] Specifically, the side baffle 201 is slidably connected to the top baffle 101 via a sliding mechanism, and the sliding mechanism includes a track 202 arranged at the outer edge of the top baffle 101, and the track 202 actually adopts a circular ring structure, which can realize 360-degree rotation of the side baffle 201 without dead angles, and a slide seat 203 arranged on the side baffle 201 and slidably connected to the track 202, and the side baffle 201 can be rotated in any horizontal direction through the slide seat 203.

[0051] When it is necessary to spread the snow-melting medium on one side of the road, it is only necessary to turn the side baffle 201 to the opposite side of the spreading direction to adjust the spreading direction. Of course, the size of the side baffle 201 can also be changed to adjust the spreading area. That is, the longer the length of the side baffle 201, the smaller the spreading area, which is conducive to the snow-melting medium falling on the lane below. The more snow-melting medium is received by the road per unit area, the faster the snow melting speed, and the more obvious the effect. It is suitable for local or single lane spreading operations. On the contrary, it is conducive to the large-scale spreading of snow-melting medium, and multiple lanes can be spread, and a large area can be spread at one time, but the amount of snow-melting medium received by the road per unit area will be reduced accordingly, and the snow melting speed will be prolonged accordingly. However, it can be dealt with by slowing down the speed of the vehicle or increasing the delivery amount of the snow-melting medium.

[0052] In addition, the track 202 and the slide 203 are mutually positioned and connected by a fixing member, so as to realize the positioning of the rotation angle and prevent arbitrary rotation. For example, the track 202 is evenly provided with a plurality of fixing holes 2021 (which may be pin holes or thread holes), and the slide 203 is provided with holes adapted thereto, and the two can be connected by a plug-in member 2031 such as a bolt or a pin to limit the position. Embodiment 3

[0053] Reference Figure 3 and Figure 7 The technical problem to be solved by this embodiment is to prevent the snowmelt medium and water from solidifying and agglomerating and clogging in extreme weather.

[0054] Specifically, a heating element 1 3012 is provided on the side of the detection plate 301 away from the spreading direction of the spreading turntable 104. The heating element 1 3012 is used to heat the detection plate 301. Even in extreme weather, the temperature of the detection plate 301 can be guaranteed to prevent the snow-melting medium such as sand from solidifying with water to form agglomerates 105. Of course, a heating element 2 can also be provided on the side baffle 201 to play a role of heat preservation together, leaving enough spreading space for the snow-melting medium.

[0055] This structure can also better adapt to different snow-melting media, because the main components of the snow-melting agent are potassium acetate and chloride salts, which will cause harm to the environment. Therefore, sand is used as a medium in some cases. Sand is easy to solidify and agglomerate in a humid and low-temperature environment and adhere to the detection plate 301 and / or the side baffle 201. Therefore, the provision of a heating component can achieve a good technical effect of preventing adhesion, and a heating temperature above the freezing point can be achieved, with low energy consumption and no excessive load.

[0056] As a further technical solution, a shielding plate 3011 for shielding the heating element 3012 is provided on the top of the detection plate 301, which can prevent foreign matter from adhering to the side of the detection plate 301 and extend the service life of related electrical components.

[0057] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0058] During the spreading operation, the snow-melting medium can be thrown out under the action of centrifugal force, and the detector can block the snow-melting medium. When the snow-melting medium touches the detection plate at high speed, the detection plate can be subjected to a certain pressure and finally make a corresponding output signal through the controller, so that the driver can make a timely judgment. If the snow-melting medium is blocked and cannot be thrown out, the detection plate will not be pressed and hit. At this time, the controller will output another signal to remind. After using the utility model, the driver can know whether the snow-melting medium is blocked at the first time, so as to make corresponding remedial measures, and there is no need for other personnel and vehicles to follow. The road can be fully and comprehensively spread in a single shift, and the working efficiency is greatly improved. Moreover, the transformation cost is very low, saving considerable cost investment.

[0059] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
