Description

Technical Field

[0001] The invention relates to the technical field of highway maintenance equipment, in particular to a multifunctional adjustable spreader. Background Art

[0002] The road surface is easy to freeze under low temperature conditions, which reduces the friction coefficient of the road surface and makes it difficult to control the vehicle when driving. In particular, traffic accidents are more likely to occur on overpasses and roads with large slopes, affecting road safety. For ice on the road surface, it is difficult to remove it with equipment such as snow shovels and snow sticks. Finally, it is necessary to spread snow melting agents through spreaders to remove ice. Considering the cost issue, industrial salt is used as snow melting agent in most cases. Because industrial salt damages steel structure bridges and roadside plants, the amount of snow melting agents spread by the spreader needs to be strictly controlled. Too much snow melting agent will cause damage to steel structure bridges and roadside plants, and too little snow melting agent will not have the effect of melting ice. Therefore, it is necessary to control the spreading range and density according to the actual situation when using it. The existing spreader is inconvenient to adjust, which makes it inconvenient to use. In addition, the snow melting agent itself has a certain viscosity and is easy to form blocks. When spreading, it is easy to cause a supporting effect on the spreading equipment of the spreader, thereby affecting the normal spreading effect. Summary of the invention

The main shaft 22 adopts a hollow shaft and a rotating rod 29 coaxially arranged with the main shaft 22 is rotatably installed inside the main shaft 22, and the rotating rod 29 is provided with a plurality of through holes, and connecting rods 30 are provided inside the plurality of through holes, one end of the connecting rod 30 is fixedly connected to the rotating rod 29, and a second bulk material blade 20 is fixed on the end of the connecting rod 30 away from the rotating rod 29, and the plurality of second bulk material blades 20 and the plurality of first bulk material blades 25 are interspersed and arranged, and the plurality of second bulk material blades 20 and the plurality of first bulk material blades 25 have the same shape.

[0024] When the device is in use, the device is placed at a position where it needs to work, and the main shaft 22 is connected to the driving device of the vehicle or a separate driving motor is provided on the spreading component, so that the output end of the driving motor is connected to the main shaft 22 in a transmission manner. The rotation of the main shaft 22 can rotate the bulk material disc 21, the first bulk material blade 25 and the second bulk material blade 20. The snow melting agent is added to the inside of the hopper 2 and reaches the conveyor belt 4 through the discharge port below the hopper 2. Under the action of the conveyor belt 4, it moves in the direction of the feed hopper 2, thereby entering the inside of the feed hopper 2, and entering the bulk material disc 21 through the feed hopper 2 and the discharge pipe 8.
