Description

Technical Field

[0001] The utility model relates to the technical field of bag-packed snow-melting agent cutting, in particular to an automatic bag-packed snow-melting agent cutting device. Background Art

[0002] Snow melting agents are mainly used to melt snow and ice in winter to ensure the smooth flow of roads, highways, airports, bridges and other facilities. During the snow removal and anti-skid process on highways, the bagged snow melting agents need to be unpacked, loaded into the snow melting agent spreading vehicle, and transported to the snowy roads for spreading and melting snow.

[0003] The existing bagged solid deicing agent is packed in one bag per ton, referred to as a "ton bag". When loading it into the deicing agent spreading vehicle, the ton bag is usually hoisted onto the vehicle tank by an electric single-beam bridge crane, and a worker stands on one side of the ton bag and cuts the packaging bag of the ton bag with a cutter, so that the deicing agent falls into the truck bed of the deicing agent spreading vehicle. However, the worker needs to stand in the truck bed or in the truck bed that is already filled with deicing agent to continue cutting the ton bag hoisted above his head. This bag cutting method is dangerous and may endanger the life of the worker if he is not careful. In addition, the cutting opening of the manual bag cutting is small, and the deicing agent filling efficiency is low. Utility Model Content

[0007] Both ends of the cutting tool extend out of the frame body; the cutting tool is connected to the vibrator through a lockable telescopic rod.

[0008] The cargo box of the snow-melting spreader is equipped with a frame with a cutting tool, which cooperates with a crane to move the hoisted bagged snow-melting agent to the blade of the cutting tool. The bagged snow-melting agent is heavy, and the lower end of the bagged snow-melting agent packaging bag can be easily cut through its own weight and the movement of the crane, making it easier for the snow-melting agent to fall into the cargo box, thereby achieving rapid loading of the snow-melting agent.

[0009] In order to reduce the risk of snow-melting agent particles flooding the vibrator or the lower part of the frame, an upwardly convex arc-shaped bulk material cover is provided on the telescopic rod. The arc-shaped bulk material cover is located above the vibrator. The upwardly convex arc-shaped bulk material cover can disperse most of the snow-melting agent particles to the outside of the frame and the vibrator.

[0010] In order to facilitate the one-time and quick cutting of the packaging bag, a plurality of puncture tools located outside the cutting knife are vertically arranged on the upper part of the frame. The puncture heads of the puncture tools are arranged upward, and the highest point height of the puncture heads is higher than the highest point height of the cutting knife. The packaging bag can be punctured in advance by the puncture tools, which is convenient for cutting by the cutting knife.

[0011] Regarding the arrangement position of the puncture tools, the puncture tools are distributed on both sides of the cutting tool along the length direction. When the hoisted bagged snow-melting agent moves downward, it first contacts the puncture head of the puncture tool, and the packaging bags on both sides of the cutting tool are punctured through the puncture head to make several holes, thereby reducing the difficulty of cutting the packaging bags, increasing the cutting opening, and facilitating rapid material blanking.

[0012] The puncture tool is arranged at a position on one side of the cutting tool such that the vertical spacing between the puncture tool and the cutting tool in the horizontal direction is 0.5-5 cm.

[0013] Regarding the specific structure of the cutting tool, the cutting tool comprises a cutting blade, and the cutting blade is an upwardly convex arc structure.

[0014] Regarding the installation positions of the plurality of cutting blades, the plurality of cutting blades are arranged crosswise or in parallel.

[0015] The connection structure between the puncture tool and the frame is that the upper part of the frame is detachably connected to a support rod along the length direction of the cutting knife, and the lower end of the puncture tool is arranged on the support rod, which is convenient for disassembly, installation and replacement of the puncture tool.

[0016] The height of the frame is adjustable according to the filling depth of the deicing agent particles in the truck bed to prevent the frame from being buried by the deicing agent particles.

[0017] Each time the bagged snow-melting agent is lifted, a long operation time is required. In order to facilitate the continuous operation of the vibrator and prevent malfunctions, a displacement sensor that can detect the position of the bagged snow-melting agent is provided at the upper end of the frame. The displacement sensor is located on the side below the cutting tool and is electrically connected to the vibrator. The vibrator can be started and stopped according to the position of the bagged snow-melting agent to avoid malfunctions caused by the vibrator working for a long time.

[0018] The beneficial effects of the utility model are:

[0019] A frame with a cutting tool is installed on the truck bed of the snow-melting spreader, and the hoisted bagged snow-melting agent is moved to the blade of the cutting tool with the help of a crane. The bagged snow-melting agent is heavy, and the lower end of the bagged snow-melting agent packaging bag can be easily cut by its own weight and the movement of the crane, so that the snow-melting agent can fall into the truck bed and be loaded;

[0020] If the packaging bag of the snow-melting agent cannot be cut at one time or the cutting opening is small, start the vibrator to drive the cutting tool to vibrate, so that the cutting tool can vibrate and cut the packaging bag;

[0021] In order to further improve the one-time cutting effect of the bagged snow-melting agent packaging bag, a puncture tool is provided, which contacts the bottom of the packaging bag in advance and punctures a number of holes in the bottom of the packaging bag. This is conducive to the rapid cutting of a larger cutting opening in the packaging bag by the cutting tool when the bagged snow-melting agent continues to move downward, thereby improving the filling efficiency of the snow-melting agent.
