Description

Technical Field

[0001] The present disclosure relates to the technical field of snow melting machines, and in particular to a stirring blade with a scraper. Background Art

[0002] A snow melter, also known as a smoothie machine or slushie machine, is a machine specifically designed for making frozen drinks. These machines are primarily used in the food and beverage industry, including but not limited to ice cream parlors, cafes, bars, dessert shops, and fast food chains, for the rapid, on-site preparation of refreshing drinks such as crushed ice, smoothies, shaved ice, and milkshakes. However, in actual use, a layer of ice easily forms on the inner barrel wall of a snow melter, which not only affects the machine's efficiency but can also cause damage. Traditional blending blades only serve to stir the ingredients and are ineffective against hard layers of ice, requiring frequent downtime for manual cleaning, increasing maintenance costs and time. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a stirring knife with a scraper, aiming to solve the problems in the background technology.

[0004] In order to achieve the above-mentioned object of the invention, the first aspect of the present invention provides a stirring knife with a scraper, comprising:

[0005] The mixing blade holder serves as the supporting structure of the entire device;

[0006] A plurality of stirring blades are fixed on the stirring blade holder to stir the materials;

[0007] One of a plurality of de-icing blades or a plurality of de-icing rakes is installed on the stirring blade holder and can effectively scrape off ice on the surface of the snow melt machine evaporator.

[0008] Optionally, the de-icing blade has an arc-shaped edge structure, and its front end has an inclination angle of 20° to 45°.

[0009] Optionally, when a deicing blade is installed on the stirring blade holder, the deicing blade is fixedly connected to the front end surface of the stirring blade holder in the rotation direction.

[0010] Optionally, when a deicing rake is installed on the stirring blade holder, the deicing rake is fixedly connected to the rear end surface of the stirring blade holder in the rotation direction.

[0011] Optionally, the blade holder is rotatably mounted on the outer surface of the evaporator, and a plurality of deicing blades or a plurality of deicing rakes are close to the outer wall of the evaporator, and the rotational power of the blade holder comes from the top of the blade holder. Beneficial effects

[0012] The utility model provides a stirring knife with a scraper with beneficial effects.

[0013] This utility model features a scraper-type agitator that, when combined with a de-icing blade or rake, effectively scrapes and breaks up the ice layer on the surface of the snow melter's internal barrel. The de-icing blade's curved edge and 20° to 45° tilt angle allow it to cut through the ice more smoothly, carrying ice chips to the center as it rotates, significantly improving the snow melter's output efficiency.

[0014] 2. The present invention features a scraper-equipped mixing blade, whose stirring blades operate synchronously with the de-icing tool, ensuring uniform mixing of materials throughout the entire process. This simultaneous de-icing and mixing operation not only improves work efficiency but also reduces energy consumption and lowers operating costs. Compared to traditional, complex de-icing systems, the solution provided by this application is simple in structure, easy to manufacture and assemble, and reduces reliance on additional power sources or control systems, thereby reducing overall manufacturing and maintenance costs.

Example

[0025] Reference Figure 1-Figure 3 One embodiment of the present invention provides an embodiment of a stirring knife with a scraper, comprising:

[0026] The stirring blade holder 1 serves as the supporting structure of the entire device;

[0027] A plurality of stirring blades 2 are fixed on the stirring blade holder 1 to stir the material;

[0028] One of a plurality of de-icing blades 3 or a plurality of de-icing rakes 4 is mounted on the stirring blade holder 1 and can effectively scrape off ice on the surface of the snow melter evaporator 5 .

[0029] In some embodiments, the de-icing blade 3 has an arc-shaped edge structure, and its front end has an inclination angle of 20° to 45°.

[0030] In one example, when the de-icing blade 3 is installed on the mixing blade frame 1, the de-icing blade 3 is fixedly connected to the front end surface of the mixing blade frame 1 in the rotation direction. When the de-icing rake 4 is installed on the mixing blade frame 1, the de-icing rake 4 is fixedly connected to the rear end surface of the mixing blade frame 1 in the rotation direction.

[0031] It should be noted that the stirring blade holder 1, serving as the supporting structure of the entire device, is made of high-strength materials, such as stainless steel or wear-resistant alloy steel, to ensure sufficient strength and durability in harsh environments. The stirring blade holder 1 is designed to be installed inside the snow melter and can be connected to the drive shaft, driven by the snow melter's internal motor.

[0032] In one example, the blade holder 1 is rotatably mounted on the outer surface of the evaporator 5, and several de-icing blades 3 or several de-icing rakes 4 are close to the outer wall of the evaporator 5, and the rotational power of the blade holder 1 comes from the top of the blade holder, which facilitates the design of the power system and improves the sealing performance.

[0033] A plurality of stirring blades 2 are evenly fixed on the stirring blade holder 1 by welding, bolting or other reliable fixing methods. The function is to stir the materials and ensure that the materials are mixed evenly.

[0034] The user can choose to install one of the plurality of de-icing blades 3 or the plurality of de-icing rakes 4 according to actual needs. Both tools are designed to effectively remove the ice layer on the surface of the inner barrel of the snow melter and improve the de-icing efficiency.

[0035] When using the de-icing blade 3, it has the following features:

[0036] Arc-shaped blade edge structure: The front end of the de-icing blade 3 is designed with an arc-shaped blade edge, which helps to cut into the ice layer more smoothly. The angle of the blade edge is designed to minimize the impact on the machine itself while ensuring the cutting effect. The front end of the de-icing blade 3 has an inclination angle of 20° to 45° relative to the horizontal plane. This angle is chosen to reduce energy consumption as much as possible while maintaining good cutting performance, and to enable the blade to better adapt to ice layers of different thicknesses. The de-icing blade 3 is fixedly connected to the front end face of the mixing blade holder 1 in the rotation direction. This arrangement allows the de-icing blade 3 to contact the ice layer first during the rotation of the mixing blade, thereby achieving efficient de-icing operations. Example

[0037] This embodiment uses a de-icing rake 4 mounted on the mixing blade frame 1, fixedly connected to the rear end surface of the mixing blade frame 1 in the direction of rotation. This arrangement allows the de-icing rake 4 to further process any remaining small ice fragments after the mixing blades complete their initial mixing, ensuring a more thorough cleanup. Compared to the de-icing blade 3, the de-icing rake 4 typically has more teeth, making it suitable for thinner or broken ice layers, effectively removing any remaining ice without damaging the inner walls of the snow melter.

[0038] Before starting operation, install either the de-icing blade 3 or the de-icing rake 4 based on the state of the ice inside the snow melter. For thick, hard ice, a de-icing blade 3 with a curved edge and a 20° to 45° tilt angle is preferred. For thinner or broken ice, a de-icing rake 4 with multiple teeth can be used. The selected de-icing blade 3 or de-icing rake 4 is securely attached to the mixing blade frame 1, with the de-icing blade 3 positioned at the front end in the direction of rotation and the de-icing rake 4 at the rear end.

[0039] Once the snow melter is started, the drive shaft drives the stirring blade frame 1 and its components, the stirring blade 2, the de-icing blade 3 or the de-icing rake 4, to rotate together. If the de-icing blade 3 is installed, the de-icing blade 3 will first contact and cut into the ice layer. Due to its unique curved blade edge design and appropriate inclination angle, it can effectively scrape the ice layer from the wall of the snow melter barrel and bring it to the center area as it rotates. In the case where the de-icing rake 4 is selected, after the initial stirring, it can further break up the remaining small pieces of ice through its multi-tooth structure to ensure more thorough cleaning. While de-icing, several stirring blades 2 are also in continuous operation, responsible for stirring the material to ensure that the material is evenly mixed throughout the process. This simultaneous de-icing and stirring operation improves work efficiency while reducing energy consumption.

[0040] After completing the de-icing and mixing tasks, turn off the snow melter and the removed de-icing tools should be cleaned and maintained to prepare for the next operation.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
