Description

Technical Field

[0001] The utility model relates to the technical field of spreaders, in particular to a salt box mechanism of a snow melting agent spreader. Background Technique

[0002] A snow melting agent refers to a chemical agent that can lower the melting temperature of ice and snow. Ordinary snow melting agents are easy to obtain raw materials and low in price. Their components are mainly potassium acetate and chlorides, and they are classified according to these two. The snow melting agent melts the snow on the road by lowering the melting temperature of ice and snow, facilitating road dredging, and the effect at the spreading place is obvious. In the north, sand and snow plows are still mainly used to remove ice and snow on the road surface in winter, supplemented by snow melting agents, to ensure smooth traffic. In order to improve the spreading efficiency of the snow melting agent, a vehicle-mounted spreader is used to spread the snow melting agent.

[0003] The existing spreader is mainly composed of a salt box mechanism, a conveying mechanism and a spreading mechanism. The snow melting agent is added into the salt box mechanism, conveyed through the conveying technology, and spread by the spreading mechanism. The existing snow melting agent is directly added into the salt box mechanism. The salt box mechanism lacks a crushing structure for the snow melting agent. The snow melting agent itself is easy to agglomerate. The agglomerated snow melting agent is easy to be blocked when being conveyed by the conveying mechanism. At the same time, if the agglomerated snow melting agent is directly spread, it will cause waste. Therefore, a salt box mechanism of a snow melting agent spreader is proposed.

[0005] To achieve the above object, the utility model provides the following technical solution: A salt box mechanism of a snow melting agent spreader, including a conveying mechanism and a spreading mechanism located at the output end of the conveying mechanism. A plurality of salt boxes fixedly communicated with the conveying mechanism are installed on the conveying mechanism. Brackets are installed on both side walls of the plurality of salt boxes.

A pressing roller located above the crushing net is rotatably connected to the outer wall of the rotating shaft. The threaded rod is rotatably connected between the two support plates. A driving motor is installed on the outer wall of one of the support plates connected to the threaded rod. The output shaft of the driving motor is fixedly connected to one end of the threaded rod.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art in the technical field of the present application without making creative efforts belong to the protection scope of the present utility model

[0023] Please refer to Figures 1-5 , the salt box mechanism of the snow melting agent spreader in this embodiment includes a conveying mechanism 1 and a sowing mechanism 2 located at the output end of the conveying mechanism 1. A plurality of salt boxes 3 fixedly communicated with the conveying mechanism 1 are installed on the conveying mechanism 1. Bracket 17 is installed on both side walls of the plurality of salt boxes 3. A crushing screen 5 is installed at the upper opening of the salt box 3. Two support plates 4 are installed on the side walls of the two salt boxes 3 at both ends by bolts. A threaded rod 7 and a limiting rod 6 are respectively installed between two groups of support plates 4 on the long sides of both sides of the plurality of salt boxes 3. A plurality of connecting sleeves 9 are penetrated through the outer walls of the threaded rod 7 and the limiting rod 6. The threaded rod 7 is threadedly connected with the connecting sleeve 9 on its outer wall. The connecting sleeve 9 is slidably connected with the limiting rod 6 on its inner wall. A rotating shaft 10 is rotatably connected between the connecting sleeves 9 on the outer walls of the adjacent limiting rod 6 and the threaded rod 7. A pressure roller 11 located above the crushing screen 5 is rotatably connected to the outer wall of the rotating shaft 10. The threaded rod 7 is rotatably connected between the two support plates 4. A driving motor 8 is installed on the outer wall of one of the support plates 4 connected to the threaded rod 7. The output shaft of the driving motor 8 is fixedly connected to one end of the threaded rod 7

[0024] Such as Figures 1-4As shown in the figure, the structure of the salt box mechanism in the present utility model is similar to that of the salt box mechanism of the spreader. The main improvement of the present utility model lies in providing a salt box mechanism for crushing the snow melting agent to ensure the transportation and spreading of the snow melting agent and reduce waste. The conveying mechanism 1 and the spreading mechanism 2 in the present utility model are both prior arts. The snow melting agent is added into the salt box 3 for storage and then falls to the conveying mechanism 1. The conveying mechanism 1 transports the snow melting agent to the spreading mechanism 2, and the spreading mechanism 2 spreads the snow melting agent onto the road surface. When adding the snow melting agent into the salt box 3, the snow melting agent directly falls and contacts the crushing net 5. The crushing net 5 first cuts part of the snow melting agent, and the cut snow melting agent directly falls into the salt box 3. Part of the snow melting agent falls on the crushing net 5 and is supported by the crushing net 5. At this time, the driving motor 8 is started to work. The driving motor 8 drives the threaded rod 7 to rotate, and the threaded rod 7 drives a plurality of connecting sleeves 9 to move. The connecting sleeve 9 drives the pressure roller 11 to move through the rotating shaft 10. The other end of the rotating shaft 10 drives another connecting sleeve 9 to slide on the outer wall of the limiting rod 6. The plurality of support plates 4 respectively support the driving motor 8, the threaded rod 7 and the limiting rod 6. The moving pressure roller 11 squeezes the snow melting agent accumulated on the crushing net 5, so that the squeezed snow melting agent is crushed through the crushing net 5. After being crushed, it continues to fall into the salt box 3, thereby realizing the crushing of the snow melting agent, making the snow melting agent scattered and spread by the spreading mechanism 2, and reducing the waste of the snow melting agent.

[0025] Among them, the above-mentioned driving motor 8 can be purchased on the market. It belongs to a mature technology and has been fully disclosed. Therefore, it is not repeated in the specification. The driving motor 8 is equipped with a power connection line, and it is electrically connected to the external main controller and the 220V phase voltage (or 380V line voltage) through the power cord. And the main controller can be a conventional known device such as a computer that plays a control role.

[0026] As Figure 4 shown in the figure, a rack 13 is fixedly connected between the two support plates 4 connected to the threaded rod 7. One end of the rotating shaft 10 passes through the connecting sleeve 9 and is fixedly connected with a gear 14. The gear 14 is meshed with the rack 13. When the threaded rod 7 drives the connecting sleeve 9 to move, the connecting sleeve 9 drives the rotating shaft 10 to move. The gear 14 on the outer wall of the rotating shaft 10 is meshed with the rack 13, thereby driving the rotating shaft 10 to rotate. The rotating shaft 10 drives the pressure roller 11 to rotate. The rotating pressure roller 11 squeezes and crushes the snow melting agent falling on the crushing net 5. The pressure roller 11 will rotate when moving, so that the pressure roller 11 can be pressed above the snow melting agent, avoiding the phenomenon that the pressure roller 11 pushes the snow melting agent without pressing it down, and improving the crushing effect.

[0027] As Figure 4 shown in the figure, a plurality of crushing grooves 12 are formed on the outer wall of the pressure roller 11. The plurality of crushing grooves 12 are evenly formed on the outer wall of the pressure roller 11. The crushing grooves 12 on the outer wall of the pressure roller 11 can further improve the crushing effect of pressing the snow melting agent down and improve the practicability.

[0028] As Figure 2 , 3 shown, a plurality of stabilizing frames 15 are installed on both sides of the salt box 3 by bolts. The threaded rod 7 and the rack 13 penetrate through a plurality of stabilizing frames 15 on the same side, and the limiting rod 6 penetrates through a plurality of stabilizing frames 15 on the other side. The threaded rod 7 is rotatably connected to the stabilizing frame 15 it penetrates. The plurality of stabilizing frames 15 respectively support the limiting rod 6, the threaded rod 7 and the rack 13, improving stability and ensuring strength. When the threaded rod 7 rotates, it rotates on the outer wall of the stabilizing frame 15.

[0029] As Figure 1 shown, the inner wall of the lower end of the salt box 3 is of a hopper-shaped structure, and a vibration motor 18 is installed on the side wall of the salt box 3. The salt box 3 with a hopper-shaped lower end can facilitate the falling of the snow melting agent into the conveying mechanism 1 for conveying. At the same time, by using the vibration motor 18 on its outer wall, the snow melting agent can be prevented from adhering to the inner wall of the salt box 3.

[0030] As Figure 1 , 5 shown, a support frame 16 is fixedly installed on the periphery of the crushing mesh 5. The crushing mesh 5 is movably installed on the upper end face of the salt box 3 through the support frame 16, and the edge of the upper end face of the salt box 3 supports the support frame 16. The crushing mesh 5 is movably placed at the upper opening of the salt box 3 through the support frame 16, which is convenient for disassembly, installation and maintenance.

[0031] As Figure 1 , 3 , 4, 5 shown, the minimum distance between the pressure roller 11 and the crushing mesh 5 is not greater than 5 cm, and the mesh aperture of the crushing mesh 5 is not greater than 2 cm. By controlling the distance between the pressure roller 11 and the crushing mesh 5 and the mesh aperture of the crushing mesh 5, the crushing effect on the snow melting agent can be ensured.

[0032] In this embodiment, the implementation steps are as follows: When adding the snow melting agent into the salt box 3, the snow melting agent directly falls and contacts the crushing mesh 5. The crushing mesh 5 first cuts part of the snow melting agent, and the cut snow melting agent directly falls into the salt box 3. Part of the snow melting agent falls on the crushing mesh 5 and is supported by the crushing mesh 5. At this time, the driving motor 8 is started to work. The driving motor 8 drives the threaded rod 7 to rotate. The threaded rod 7 drives a plurality of connecting sleeves 9 to move. The connecting sleeve 9 drives the pressure roller 11 to move through the rotating shaft 10. The gear 14 on the outer wall of the rotating shaft 10 meshes with the rack 13, thereby driving the rotating shaft 10 to rotate. The rotating shaft 10 drives the pressure roller 11 to rotate. The other end of the rotating shaft 10 drives another connecting sleeve 9 to slide on the outer wall of the limiting rod 6. The plurality of support plates 4 respectively support the driving motor 8, the threaded rod 7 and the limiting rod 6. The moving and rotating pressure roller 11 squeezes the snow melting agent piled up on the crushing mesh 5, so that the squeezed snow melting agent is crushed through the crushing mesh 5. After being crushed, it continues to fall into the salt box 3. The snow melting agent falling into the salt box 3 is conveyed to the spreading mechanism 2 through the conveying mechanism 1 and is sprinkled out through the spreading mechanism 2.

[0033] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art to which the present utility model pertains, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
