An adjustable snow-melting agent spreader

Abstract

This utility model belongs to the field of highway maintenance technology and discloses an adjustable de-icing agent spreader. It includes a suspension device for installation and fixation, a housing device for automatically carrying the de-icing agent downwards, and a spraying device for rotating and spreading the de-icing agent below the housing device. A feeding device for adjusting the feeding speed of the de-icing agent by moving up and down is located in the middle of the housing device. By driving the conical flow-limiting block up and down with a first electric push rod, the gap between the block and the feeding pipe can be precisely and continuously adjusted.

Description

Technical Field

[0001] This utility model belongs to the field of highway maintenance technology, and in particular relates to an adjustable de-icing agent spreader. Background Technology

[0002] De-icing agent application is a key technology for snow removal and traffic safety in highway maintenance during winter. Its core principle lies in lowering the freezing point of ice and snow through salts, accelerating the melting process to ensure road safety. De-icing agents typically contain sodium chloride and calcium chloride as main components. After application, they quickly penetrate the ice and snow layer, disrupting the crystal structure and achieving efficient de-icing. This technology is simple to operate, requires no complex equipment, and significantly improves the emergency response capabilities of urban traffic and highways. Especially in the initial stages of snowfall or the post-snow icing phase, it effectively prevents traffic accidents caused by snow compaction.

[0003] Compared with Chinese Patent No. CN223358195U, an automatic de-icing agent spreading device is disclosed, including a mounting frame, a fixing frame, a controller, a storage box, a grid plate, a feeding mechanism, and a spreading mechanism. A spreading mechanism is provided at the bottom of the feeding mechanism, and an electric gate valve is used to easily control the feeding speed of the de-icing agent, thereby controlling the amount of de-icing agent spread. By starting a motor, a rotating plate and multiple actuating plates rotate. The rotating actuating plates facilitate the flicking and ejection of the de-icing agent, and the two rotating plates rotate in opposite directions, allowing the spreading mechanism to spread the de-icing agent to both sides, improving the spreading effect of the automatic de-icing agent spreading device. Furthermore, by controlling the speed of the motor, the speed of the rotating plate and multiple actuating plates can be easily controlled, thus facilitating the control of the de-icing agent spreading range.

[0004] However, the aforementioned patent uses an electric gate valve to control the feeding speed, which can easily cause the de-icing agent to fall to the center of the rotating plate, resulting in the inability to be sprayed. It can also easily form bridging in the guide shell, causing the de-icing agent to be unable to flow down. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable de-icing agent spreader to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable de-icing agent spreader includes a suspension device for installation and fixation, a housing device for automatically carrying the de-icing agent downwards is installed in the middle of the suspension device, and a spraying device for rotating and spreading the de-icing agent is set below the housing device. A feeding device for adjusting the feeding speed of the de-icing agent by moving up and down is set in the middle of the housing device. The housing device includes a storage box, a guide cone is set at the bottom of the storage box, and a feeding pipe is set at the bottom of the guide cone. The spraying device includes a rotary spraying disc, a servo motor is set at the bottom of the rotary spraying disc, and several spraying plates are evenly distributed around the circumference of the rotary spraying disc. The feeding device includes a fixed frame, a first electric push rod is installed in the middle of the fixed frame, an adjusting rod is set below the first electric push rod, the adjusting rod is fixedly connected to the telescopic end of the first electric push rod through a connecting mechanism, and a flow limiting block is set at the bottom of the adjusting rod. The flow limiting block is conical, and the bottom diameter of the flow limiting block is larger than the diameter of the feeding pipe and smaller than the diameter of the rotary spraying disc.

[0008] Furthermore: the connecting mechanism includes a connecting sleeve at the top of the adjusting rod, on which a locking bolt is installed.

[0009] Furthermore: the adjusting rod has several obstacle-breaking rods evenly distributed around its circumference.

[0010] Furthermore: a guide column is provided in the middle of the swirl disc, and a conical guide head is provided at the top of the guide column.

[0011] Furthermore: the spraying plate is set vertically and welded together with the swirl plate and the guide column.

[0012] Furthermore: the suspension device includes a support base plate, on which two cantilever arms are symmetrically mounted, a fixing baffle is provided between the bottom of the cantilever arms, and a mounting plate is provided between the top of the cantilever arms, with two mounting holes symmetrically provided on the mounting plate.

[0013] Furthermore, the fixed baffle is arc-shaped, and two adjustment mechanisms for adjusting the spraying range are symmetrically arranged at both ends of the fixed baffle.

[0014] Furthermore, the adjustment mechanism includes a movable baffle that is hinged to a fixed baffle at one end, and a second electric push rod is installed behind the movable baffle. The second electric push rod is hinged to the movable baffle and the supporting base plate respectively.

[0015] Furthermore: the mounting hole is a long slot shape.

[0016] Compared with existing technologies, the beneficial effects are:

[0017] The first electric push rod drives the conical flow-limiting block to move up and down, allowing for precise and continuous adjustment of the gap between it and the discharge pipe. This ensures that the de-icing agent is distributed along the flow-limiting block to the circumference of the rotary blasting disc, while also achieving linear control of the de-icing agent flow rate. This avoids the uneven distribution problem caused by the "on-off" discharge of traditional equipment, and can precisely match the distribution amount according to the road surface ice and snow conditions, greatly reducing the waste of de-icing agent while ensuring the snow-melting effect. The design of the guide column and conical guide head effectively prevents the de-icing agent from accumulating in the center of the rotary blasting disc, ensuring that all material is smoothly guided to the blasting plate and thrown out, eliminating dead zones in the distribution, and further ensuring the effective distribution. The uniformity of the spread; a specially designed obstacle-breaking rod, driven up and down by the first electric push rod along with the adjusting rod, can actively break up the "bridging" phenomenon caused by moisture and compaction of the de-icing agent in the storage tank, fundamentally solving the industry problem of material blockage, ensuring the continuity and stability of the spreading operation, and reducing the maintenance cost of downtime cleaning; through the innovative material adjustment mechanism, adjustable spreading range control mechanism, active obstacle-breaking mechanism, and optimized spreading disc structure, the synergistic effect achieves multiple beneficial effects such as precise and controllable material feeding, uniform and efficient spreading, stable and reliable operation, and wide applicability, significantly improving the overall performance and economy of de-icing agent spreading operations.
