Description

Technical Field

[0001] The utility model relates to the technical field of spreaders, in particular to a conveying 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 are inexpensive. Their main components are potassium acetate and chloride salts, 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 in winter, supplemented by snow melting agents, to remove ice and snow on the road surface 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 mainly consists of a salt box mechanism, a conveying mechanism, and a spreading mechanism. The snow melting agent is added into the salt box mechanism, and the snow melting agent is conveyed to the spreading mechanism through the conveying technology, and the snow melting agent is spread out through the spreading mechanism. The conveying mechanism in the existing spreader mainly consists of a blanking frame, a motor, and an auger. The snow melting agent added into the salt box mechanism falls into the blanking frame, and the motor drives the auger to rotate in the blanking frame, thereby conveying the snow melting agent, so that the snow melting agent falls from the reserved discharge port on the blanking frame to the spreading mechanism for spreading. However, in actual use, the snow melting agent is prone to caking. When the auger conveys the snow melting agent, it will cause extrusion to the snow melting agent, and further cause the phenomenon of caking of the snow melting agent. The caked snow melting agent is easy to block the discharge port. At the same time, the caked snow melting agent directly spread out will cause greater waste. Therefore, a conveying mechanism of a snow melting agent spreader is proposed. Content of the Utility Model

[0023] 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 efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5, the conveying mechanism of the snowmelt agent spreader in this embodiment includes a salt box mechanism 1, a power box 4 located at the end of the salt box mechanism 1, and a spreading mechanism 2. A conveying mechanism 3 is installed at the lower end of the salt box mechanism 1. The conveying mechanism 3 includes a feeding frame 5 communicated with the salt box mechanism 1. One end of the feeding frame 5 is provided with a feeding port 8. A driving motor 6 is installed in the power box 4. A connecting seat 11 is installed at the output end of the driving motor 6. One end of the connecting seat 11 is installed with an auger 7. The auger 7 is rotatably connected in the feeding frame 5. The bottom surface of the feeding frame 5 is fixedly connected with a feeding tray 10 corresponding to the feeding port 8. A feeding and crushing unit 9 is installed in the feeding port 8. The feeding and crushing unit 9 includes a feeding hopper 91 installed in the feeding port 8. Two crushing rollers 92 are rotatably connected in the feeding hopper 91. One end of the crushing roller 92 penetrates outside the feeding hopper 91. The feeding hopper 91 is located directly above the feeding tray 10. The connecting seat 11 is drivingly connected with the crushing roller 92 to drive the crushing roller 92 to rotate.

[0025] As Figures 1-5 shown, the structure of the spreader conveying mechanism in the present utility model is similar to that of the existing spreader conveying mechanism. The main improvement point of the present utility model is to provide a conveying mechanism 3 with a crushing function to ensure that the snowmelt agent will not agglomerate after being conveyed, guarantee the smoothness of conveying, and reduce waste. The salt box mechanism 1 and the spreading mechanism 2 in the present utility model are both prior arts. The snowmelt agent is stored in the salt box mechanism 1. When it is necessary to spread the snowmelt agent, the snowmelt agent added into the salt box mechanism 1 falls into the feeding frame 5. The driving motor 6 is started to work. The driving motor 6 drives the auger 7 and the crushing roller 92 to rotate through the connecting seat 11. The auger 7 drives the snowmelt agent falling into the feeding frame 5 to move towards the feeding port 8. The snowmelt agent falls from the feeding port 8 into the feeding hopper 91. The rotating crushing roller 92 in the feeding hopper 91 crushes the snowmelt agent entering the feeding hopper 91. The crushed snowmelt agent falls from the lower end of the feeding hopper 91 to the feeding tray 10 and is guided by the feeding tray 10 into the spreading mechanism 2 for spreading, avoiding waste caused by the agglomerated snowmelt agent falling in the spreading mechanism 2 and being spread out, and at the same time avoiding the phenomenon that the agglomerated snowmelt agent causes blockage during the conveying process and affects the conveying, improving the practicability.

[0026] Among them, the above-mentioned driving motor 6 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 6 is equipped with a power connection line, and it is electrically connected to the external main controller and 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.

[0027] As Figure 5As shown, a perforation 13 is provided at the bottom surface of one end of the blanking frame 5. A belt 93 is inserted through the perforation 13. The connecting seat 11 is drivingly connected to one of the crushing rollers 92 through the belt 93. The blanking and crushing unit 9 further includes two gears 94 fixedly connected to the ends of the crushing rollers 92 respectively, and the two gears 94 mesh with each other. When the driving motor 6 drives the connecting seat 11 to rotate, the connecting seat 11 drives one of the crushing rollers 92 to rotate through the belt 93. This crushing roller 92 drives the other gear 94 to rotate through the gear 94 on its outer wall, so that the other crushing roller 92 rotates in the opposite direction, and thus the two crushing rollers 92 rotating in opposite directions crush the snow melting agent. There is no need to provide another driving source, which is convenient for crushing the snow melting agent.

[0028] As Figure 6 shown, the blanking and crushing unit 9 further includes a plurality of extrusion bars 95 fixedly connected to the outer wall of the crushing roller 92, and the plurality of extrusion bars 95 are distributed on the circumferential side of the outer wall of the crushing roller 92. The rotation of the crushing roller 92 drives the extrusion bars 95 on its outer wall to rotate, and the extrusion bars 95 on the outer wall of the crushing roller 92 are used to further improve the crushing effect on the snow melting agent, reduce the caking of the snow melting agent, and thus improve the utilization rate of the snow melting agent and reduce waste.

[0029] As Figure 6 shown, the extrusion bars 95 on the outer walls of the two crushing rollers 92 are distributed in a staggered manner, the minimum distance between the two crushing rollers 92 is greater than the length of the extrusion bars 95, and the extrusion bars 95 on the outer walls of the two crushing rollers 92 rotate in a staggered manner. When crushing the snow melting agent, the extrusion bars 95 rotating in a staggered manner on the outer walls of the two crushing rollers 92 crush the snow melting agent, and thus reduce the possibility of the snow melting agent caking.

[0030] As Figure 3 、 5 shown, a baffle 12 is fixedly connected to the inner bottom surface of the blanking frame 5. The connecting seat 11 penetrates through the baffle 12 and is rotatably connected thereto. The baffle 12 shields the belt 93. The baffle 12 shields part of the belt 93 and the connecting seat 11, avoiding the phenomenon that the snow melting agent contacts the belt 93 and causes corrosion, and improving the service life.

[0031] As Figure 5 、 6 shown, slots 96 are provided on both sides inside the hopper 91. Plug plates 97 are movably inserted into the slots 96, and the plug plates 97 shield the blanking port 8. When the spreading of the snow melting agent stops, the plug plates 97 are moved and inserted into the slots 96. The plug plates 97 shield the blanking port 8, thereby avoiding moisture from entering its interior from the blanking port 8 and at the same time blocking the blanking. When the snow melting agent needs to be discharged, the plug plates 97 can be pulled outwards to open the blanking port 8.

[0032] As Figure 5 、 6As shown, the length of the insertion plate 97 is greater than that of the slot 96, and one end of the insertion plate 97 extends outside the blanking tray 10; the insertion plate 97 can be moved outside the blanking tray 10 to avoid the blanking tray 10 blocking the insertion plate 97 and making it inconvenient to open and close the blanking port 8.

[0033] In this embodiment, the implementation steps are as follows: when it is necessary to spread the snow melting agent, the snow melting agent added into the salt box mechanism 1 falls into the blanking frame 5. Start the driving motor 6 to work, and pull the insertion plate 97 outwards to open the blanking port 8. The driving motor 6 drives the auger 7 to rotate through the connecting seat 11, and the connecting seat 11 drives one of the crushing rollers 92 to rotate through the belt 93. The auger 7 drives the snow melting agent falling into the blanking frame 5 to move towards the blanking port 8. The snow melting agent falls from the blanking port 8 into the blanking hopper 91. The crushing roller 92 driven by the belt 93 drives another gear 94 to rotate through the gear 94 on its outer wall, so that the other crushing roller 92 rotates in the opposite direction. The extrusion strips 95 on the outer walls of the two crushing rollers 92 rotate in a staggered manner to crush the snow melting agent. The crushed snow melting agent falls from the lower end of the blanking hopper 91 to the blanking tray 10 and is guided by the blanking tray 10 to fall into the spreading mechanism 2 for spreading.

[0034] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manner of the present invention. For those of ordinary skill in the art in the technical field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
