Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a spiral feeding type snow melting agent spreader. Background Art

[0002] In the winter snow removal and anti-skid work on highways, a de-icing agent spreader is required to spread de-icing agent on the highway pavement to prevent the pavement from icing. In existing equipment, the de-icing agent spreader structure is mainly composed of a silo, a feeding mechanism, and a spreading mechanism. The de-icing agent in the silo falls onto the conveyor belt of the feeding mechanism by its own gravity, and is transported to the spreading mechanism behind the equipment to complete the de-icing agent spreading operation. The feeding mechanism in the de-icing agent spreader uses a chain plate or a conveyor belt to transport the de-icing agent in the silo to the spreading plate. In actual use, it is found that the existing spreader conveying mechanism is prone to the following major problems: first, the material is easy to adhere to the conveyor belt after being wet, which reduces the transportation efficiency and causes equipment failure; second, due to the agglomeration of materials and the heavy loading weight, the transportation mechanism is insufficient in power and the material is stuck, causing the transportation mechanism to stop running; third, during the cleaning process, due to the structure of the spreader, the material under the spreader cannot be cleaned, causing equipment corrosion and damage, shortening the service life. Fourth, in actual use, due to the common weather conditions of rain and snow in the south, the snow-melting agent becomes wet and adheres to the inner wall of the spreading hopper, affecting the spreading.

[0003] The main reasons for the above shortcomings are: 1. Although some equipment has been upgraded from the initial belt transmission to the chain plate transmission method in terms of transmission principle, the spreading deicing agent is wet, agglomerated, and other reasons lead to adhesion. It is difficult to use gravity to let the spread deicing agent fall naturally and be normally transported to the rear spreading mechanism. 2. Deicing agent is corrosive to metals, and after spreading operations, deicing agent may adhere to every corner of the deicing agent spreader, causing equipment aging and failure. Existing equipment cannot use relatively high-grade stainless steel for all materials, resulting in passive maintenance and emergency repairs after failures occur, which increases the total cost of equipment use. 3. The material structure and situation of the deicing agent in the actual operation process are overly optimistic, and there are no proactive solutions to problems such as agglomeration and humidity. The impact of climate differences between the north and south of the country on the spreading material is not fully considered. Utility Model Content

[0004] Purpose of the utility model: The technical problem to be solved by the utility model is to provide a spiral feeding snow melting agent spreader in view of the shortcomings of the prior art.

[0006] In the utility model, a discharge port is arranged at the bottom side of the end of the auger conveyor, and a baffle plate is arranged at the bottom of the discharge port.

[0007] In the utility model, the silo is a V-shaped silo.

[0008] In the utility model, a mesh cover is provided on the top of the silo.

[0009] In the utility model, a vibration motor is arranged on the outer side of the auger conveyor.

[0011] Beneficial effect: The design of the V-shaped silo of the utility model can not only improve the transportation capacity of the deicing agent, but also reduce the amount of deicing agent remaining on the inner wall of the deicing agent silo. At the same time, it is made entirely of stainless steel and has stronger corrosion resistance than current products, which greatly reduces the workload in cleaning after completing the work task.

[0012] Auger conveyors are suitable for transporting small particle materials, dry powder materials, snow-melting agents and other types of materials with high efficiency. According to actual measurements, the residual amount is 0.01 kg for every 5 kg of snow-melting agent transported, which is significantly lower than the residual amount of belt and chain conveyors.

DETAILED DESCRIPTION

[0019] Example:

[0020] like Figure 1 The present embodiment provides a spiral feeding snow melting agent spreader, including a silo, wherein the bottom of the silo is provided with more than three discharge ports, an arched flow guide upper adjustment member 26 is provided above the discharge port, a flow guide member 27 is provided at the discharge port, an auger conveyor 30 is provided at the bottom side of the silo, and a spreading mechanism is provided at the end of the auger conveyor 30, and the spreading mechanism includes a spreading disc motor 33, a spreading disc 17, and a spreading disc shaft 16, and the spreading disc motor 33 drives the spreading disc 17 to rotate through the spreading disc shaft 16. A discharge port is provided at the bottom side of the end of the auger conveyor 30, and a baffle plate 12 is provided at the bottom of the discharge port. The silo is a V-shaped silo. A mesh cover 1 is provided at the top of the silo. A vibration motor 5 is provided on the outside of the auger conveyor 30. The auger conveyor 30 is driven by an auger motor 34.

[0021] The spreader silo adopts a V-shaped inner silo, which is convenient for the snow-melting agent to slide down, without material accumulation, and easy to clean. The upper part of the silo is covered with a mesh cover to prevent large pieces of material from entering the silo and damaging the conveying device. The upper waterproof cover can ensure the dryness of the snow-melting agent in rainy and snowy weather. The inverted V device inside the silo reduces the pressure of the spiral feeder and extends its service life. At the same time, it makes the snow-melting agent more evenly distributed in the silo. The spreader has a single-sided spreading function, which can be achieved by adjusting the left and right baffles.

[0022] The stainless steel box is used as a storage device for the deicing agent. In order to fully consider that the deicing agent will affect the spreading function after the spiral feeder exceeds the rated pressure due to its own gravity during the actual operation, the interior of the box is designed as a V-shaped structure to prevent the wet deicing agent from adhering to the inside of the box. The box is made of 304 stainless steel. After the deicing agent enters the spiral feeder, it is sent to the rear spreader in a spiral manner. In view of the damp and agglomerated conditions, the spiral feeder is designed with a large torque, which can have a certain crushing function for the agglomerated deicing agent while transporting the deicing agent. At the same time, the spiral blades are made of 304 stainless steel, which has strong corrosion resistance. When the deicing agent is transported to the rear spreader, it can achieve uniform transportation and the forced stirring function of the spiral feeder, ensuring that the deicing agent entering the spreader is evenly and sparsely crushed, and the agglomerated deicing agent will not block the feed hole of the spreader.

[0023] In terms of power, the machine of this embodiment uses a four-stroke gasoline engine as the power source, which drives the hydraulic motor to output power. Combined with the electronic control system, the operation of the whole machine can be controlled by wire or wireless, and the material transportation speed can be adjusted at the same time, and the amount of snow melting agent spread can be adjusted as needed. Because the whole machine has its own power, it can be flexibly installed on equipment such as dump trucks and flatbed trucks. The whole machine is easy to clean, because the spiral feeder has its own closed stirring space, and the snow melting agent of the previous equipment will not remain under the spreader to cause equipment corrosion. The whole machine uses 304 stainless steel with strong corrosion resistance.

[0024] Spreading efficiency: According to the actual measurement of the transportation efficiency of conventional belt and chain transport snow-melting agent spreaders, the transportation efficiency of existing snow-melting agent spreaders is 5.66kg / s. According to the statistics of historical experience, the snow-melting agent spreading operation speed under this transportation efficiency is 40km / h. The snow-melting agent transportation efficiency of the snow-melting agent spreader spiral feeder needs to be increased from the current 5.66kg / s to 7.1kg / s (25470kg / 3600s=7.1kg / s).

[0025] The V-shaped silo design can not only improve the transportation capacity of the deicing agent, but also reduce the amount of deicing agent remaining on the inner wall of the deicing agent silo. At the same time, it is made entirely of stainless steel, which is more corrosion-resistant than current products, greatly reducing the workload in cleaning after completing the work task.

[0026] Regarding the selection of the core component, the screw feeder, the use of a shafted screw feeder can be suitable for the transportation of small particle materials, dry powder materials, snow-melting agents and other types of materials with high efficiency. After actual measurement, the residual amount is 0.01 kg for every 5 kg of snow-melting agent transported, which is significantly lower than the residual amount of belt and chain conveyors.

[0027] After the whole machine is made of stainless steel, the corrosion resistance of the spiral feeder, box and other parts is greatly improved, and it is expected that the service life of the box and conveyor parts can be doubled.

[0028] The utility model provides a concept and method of a spiral feeding snow melting agent spreader. There are many methods and ways to implement the technical solution. The above is only the preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications should also be regarded as the protection scope of the utility model. All components not specified in this embodiment can be implemented by existing technologies.
