Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spreaders, in particular to a spreading 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 easily available and low in price. Their components are mainly potassium acetate and chlorides, and they are classified into these two types. 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 site 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 spreaders mainly consist of a salt box mechanism, a conveying mechanism, and a spreading mechanism. The snow melting agent is added to the salt box mechanism, and is conveyed to the spreading mechanism through the conveying technology, and the snow melting agent is spread through the spreading mechanism. However, in actual use, the snow melting agent is prone to caking, and the existing spreading mechanism lacks a crushing structure for the snow melting agent. If the caked snow melting agent is directly spread out, it will cause great waste. Moreover, some of the snow melting agents used have relatively large particles. When spreading the snow melting agent on roads with less snow, after the relatively large-particle snow melting agent is spread out, it will result in a large amount of snow melting agent used per square meter of the road, causing waste. Therefore, a spreading mechanism of a snow melting agent spreader is proposed. Content of the Utility Model

[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 without creative work shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-5 , the sowing mechanism of the snow melting agent spreader in this embodiment includes a salt box mechanism 1, a power box 3 located at the end of the salt box mechanism 1, and a conveying mechanism 2 located at the bottom of the salt box mechanism 1. A sowing mechanism 4 is installed at the lower end of the power box 3. The sowing mechanism 4 includes a driving motor 17 installed in the power box 3. The output end of the driving motor 17 is connected to a transmission shaft 6. A sowing disc 7 is installed at the lower end of the transmission shaft 6. A plurality of sowing strips 8 are fixedly connected to the upper surface of the sowing disc 7. Connecting plates 10 are fixedly installed on the outer walls on both sides of the power box 3 through bolts. A crushing disc 9 located directly above the sowing disc 7 is fixedly connected between the two connecting plates 10. The crushing disc 9 is sleeved outside the transmission shaft 6. The crushing disc 9 is located below the output end of the conveying mechanism 2. A crushing and extrusion block 11 is fixedly connected to the outer wall of the transmission shaft 6. A blocking unit 5 for blocking the snow melting agent is installed on the bottom surface of the power box 3.
[0024] Such as Figures 1-5As shown in the figure, the sowing mechanism structure of the spreader in the present utility model is similar to that of the existing spreader. The main improvement of the present utility model lies in that before the sowing mechanism 4 sows the snow melting agent, it crushes the snow melting agent to reduce the waste of the snow melting agent. The salt box mechanism 1 and the conveying mechanism 2 in the present utility model are both prior arts. The snow melting agent is added into the salt box mechanism 1. When sowing, the conveying mechanism 2 conveys the snow melting agent to the crushing disk 9. Start the driving motor 17 to work. The driving motor 17 drives the transmission shaft 6 to rotate. The transmission shaft 6 drives the sowing disk 7 and the crushing and extrusion block 11 to rotate. The snow melting agent falling on the crushing disk 9 enters the lower tubular interior of the crushing disk 9. The rotation of the crushing and extrusion block 11 crushes the snow melting agent entering the lower tubular interior of the crushing disk 9. The crushed snow melting agent falls on the sowing disk 7. The rotating sowing disk 7 drives the sowing strip 8 to rotate. The sowing strip 8 throws out the snow melting agent falling on the sowing disk 7 by centrifugal force for sowing. The snow melting agent falling on the sowing disk 7 is crushed and then sown out, avoiding the waste caused by the lump sowing of the snow melting agent and improving the practicability.
[0025] Among them, the driving motor 17 mentioned above can be purchased on the market. It belongs to mature technology and has been fully disclosed. Therefore, it is not repeated in the specification. The driving motor 17 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 line. And the main controller can be a conventional known device such as a computer that plays a control role.
[0026] As Figure 5 shown, a plurality of crushing grooves 12 are formed on the outer wall of the crushing and extrusion block 11, and the plurality of crushing grooves 12 are all inclined; the crushing grooves 12 are used to improve the crushing effect of the crushing and extrusion block 11 on the snow melting agent and prevent the snow melting agent from forming lumps.
[0027] As Figure 2 、 4 、5 shown, the inner bottom surface of the crushing disk 9 is of an inclined structure, and the lowest point of the inner bottom surface of the crushing disk 9 is located in the middle thereof; the crushing disk 9 with an inclined inner bottom surface can guide the snow melting agent, facilitate the snow melting agent to slide into the lower tubular interior of the crushing disk 9, and further facilitate the rapid crushing and sowing of the snow melting agent.
[0028] As Figure 5 shown, an extrusion ring 13 is fixedly connected to the outer wall of the crushing disk 9. The extrusion ring 13 is located outside the crushing and extrusion block 11. There is a gap between the extrusion ring 13 and the crushing and extrusion block 11. The inner wall of the upper end surface of the extrusion ring 13 is of an inclined surface structure, and a plurality of crushing openings 14 are formed on the inner wall of the extrusion ring 13; the extrusion ring 13 is used in cooperation with the crushing and extrusion block 11 to crush the snow melting agent. The crushing grooves 12 on the crushing and extrusion block 11 cooperate with the crushing openings 14 on the extrusion ring 13, which can improve the crushing effect on the snow melting agent and reduce the possibility of the snow melting agent caking during sowing.
[0029] As Figure 4 , 5 shown, a plurality of spiral bars 15 are fixedly connected to the outer wall of the transmission shaft 6, and the spiral bars 15 are slidably connected to the inner bottom surface of the crushing disc 9; when the transmission shaft 6 rotates, it drives the spiral bars 15 to rotate, and the spiral bars 15 push the snow melting agent on the crushing disc 9, avoiding the phenomenon that the snow melting agent adheres to the crushing disc 9 and cannot enter the lower tubular interior for crushing, improving the practicability.
[0030] As Figure 4 , 5 shown, the spiral bar 15 is of an arc structure, and the concave surface of the side wall of the spiral bar 15 is in the same direction as the rotation direction of the transmission shaft 6; when the arc-shaped spiral bar 15 rotates, it guides the snow melting agent falling on the crushing disc 9, enabling the snow melting agent to quickly enter the lower tubular interior of the crushing disc 9 for crushing, improving the crushing efficiency.
[0031] As Figure 2 , 3 shown, both ends of the bottom plate of the power box 3 extend outside the side wall of the power box 3, and a plurality of adjustment holes 16 are opened on the upper surfaces at both ends of the bottom surface of the power box 3. The blocking unit 5 includes a baffle 51 installed at the bottom of the power box 3. The middle of the baffle 51 is installed on the bottom surface of the power box 3 through a connecting member. The baffle 51 is located outside the sowing disc 7, and traction rods 52 are installed on the outer walls at both ends of the baffle 51. One end of the traction rod 52 is movably inserted into the adjustment hole 16; the baffle 51 can be used to block part of the outside of the sowing disc 7, and by inserting the traction rod 52 into different adjustment holes 16, the baffle 51 can be driven to bend. According to different bending angles of the bent baffle 51, the blocking area can be increased and decreased, improving the adaptability to the sowing of the snow melting agent.
[0032] In this embodiment, the implementation steps are as follows: during sowing, the conveying mechanism 2 conveys the snow melting agent to the crushing disc 9, starts the driving motor 17 to work, the driving motor 17 drives the transmission shaft 6 to rotate, the transmission shaft 6 drives the sowing disc 7 and the crushing and squeezing block 11 to rotate, the snow melting agent falling on the crushing disc 9 enters the lower tubular interior of the crushing disc 9, and the rotation of the crushing and squeezing block 11 cooperates with the extrusion ring 13 to crush the snow melting agent entering the lower tubular interior of the crushing disc 9. The crushed snow melting agent falls on the sowing disc 7, and the rotating sowing disc 7 drives the sowing bar 8 to rotate, and the sowing bar 8 throws out the snow melting agent falling on the sowing disc 7 by centrifugal force for sowing.
[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, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions, 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.
