Abstract
Description
Technical Field
[0001] The present invention relates to a multi - level adaptive linkage snow compactor and method after snowmaking in a ski resort, belonging to the technical field of snow compaction equipment. Background Art
[0002] The compaction and shaping of ski slopes are the core links to ensure skiing safety and competitive performance. Although the artificial snowmaking technology is mature, the snow layer formed after snowmaking generally has problems such as low density (usually 0.1 - 0.2 g / cm 3 ), uneven hardness (loose surface layer, ice particles or lumps inside), etc., and it is necessary to rely on snow compaction equipment for secondary treatment to achieve the standardization of ski slopes. The current mainstream snow compaction technologies are mainly divided into two categories: mechanical roller compaction type and vibration type.
[0003] For mechanical roller compaction equipment, a steel roller is pressed on the snow layer by hydraulic drive. Such equipment has insufficient processing capacity for ice particles or lumps in the snow layer, and local bulges or depressions occur on the snow surface after compaction, with a flatness error of 5 - 10 mm. More critically, the rigid roller is difficult to fit complex terrains such as wave - shaped slopes and jump - platform bases. The measured proportion of areas with uneven pressure distribution exceeds 30%, and manual secondary trimming is required, reducing the operation efficiency by 40%.
[0004] Vibrating snow compaction equipment improves the density of the snow layer through high - frequency vibration, but there are problems such as poor energy consumption economy and secondary damage to the snow surface, resulting in a significant increase in long - term operating costs. At the same time, the high - frequency vibration causes the surface snow particles to splash, forming a "fish - scale - like" texture, and the fluctuation range of the friction coefficient expands to 0.04 - 0.12, directly affecting the stability of the skiing speed.
[0005] In summary, the existing technology urgently needs to break through the integrated design of synchronous crushing of snow layer hard blocks and multi - level gradient compaction, solve the problems of adaptive pressure adjustment and energy consumption optimization for complex terrains, and achieve closed - loop control of the flatness of the snow surface after compaction. Summary of the Invention
[0006] Aiming at the deficiencies of the existing technology, the present invention provides a multi - level adaptive linkage snow compactor after snowmaking in a ski resort. After collecting the miscellaneous snow, it enters the box through the snow inlet hole. First, it is preliminarily and periodically broken by the breaking rod in the breaking device to prevent large snow blocks from entering and blocking the subsequent process; then it is conveyed to the grinding device by a conveyor belt for deep grinding to make the miscellaneous snow into powder form. A multi - level and specific - structure grinding method is adopted to ensure thorough treatment of the miscellaneous snow and guarantee uniform snow laying in the follow - up.
[0007] The present invention also provides a snow compaction method for the above - mentioned multi - level adaptive linkage snow compactor after snowmaking in a ski resort.
[0008] The technical solution of the present invention is as follows:
[0009] A multi-stage adaptive linkage snow compaction device after snowmaking in a ski resort, comprising a box body, a crushing device, a conveying device, a grinding device and a flattening device. Among them, a snow inlet hole is provided at the front end of the box body, a crushing device is arranged inside the box body, the crushing device faces the snow inlet hole, a conveying device is arranged below the crushing device, the conveying device is inclined, a grinding device is arranged inside the box body on one side of the top of the conveying device, a snow discharge hole is arranged on the box body below the grinding device, and a flattening device is arranged at the rear end of the box body.
[0010] Preferably according to the present invention, the crushing device includes a transmission shaft, a mounting frame, a support rod and a crushing rod. The transmission shaft is horizontally arranged inside the box body, several cross-shaped mounting frames are sleeved on the transmission shaft, several support rods are horizontally arranged on the mounting frames, several crushing rods are arranged side by side on the support rods, and the mounting frames, support rods and crushing rods adopt an outer frame hollow design, which extends the working distance and avoids blockage at the same time.
[0011] Preferably according to the present invention, the crushing rod and the support rod are inclined, and the inclination angle is 30°-45°. This inclination angle helps the material to be smoothly transmitted along with the conveying device while being crushed, and avoids the accumulation of miscellaneous snow inside the equipment.
[0012] Preferably according to the present invention, the crushing rod extends out of the snow inlet hole to improve the snow inlet efficiency.
[0013] Preferably according to the present invention, the conveying device is a conveyor belt. The driving motor inside the conveyor belt is connected to one end of the transmission shaft through a belt, and the driving motor drives the crushing device and the conveying device to work simultaneously, ensuring that the speeds of the two devices are the same during operation, and avoiding the blockage of the snow inlet hole of the crushing device caused by the too fast speed of the conveying device.
[0014] Preferably according to the present invention, the grinding device includes a grinding motor, a gear and a spiral grinding shaft. Three spiral grinding shafts are horizontally arranged inside the box body, and one end of the spiral grinding shaft is meshed with the grinding motor through a gear.
[0015] Preferably according to the present invention, the flattening device includes a flattening roller and a convex plate. The flattening roller is horizontally arranged inside the box body, convex plates are evenly arranged on the flattening roller, and one end of the flattening roller is meshed with the output shaft of the grinding motor through a gear.
[0016] The snow compaction method of the above multi-stage adaptive linkage snow compaction device after snowmaking in a ski resort is as follows:
[0017] (1) Install the snow compaction device at the front end of the snowplow and drive the snow compaction device forward. During the forward movement, the front miscellaneous snow enters the box body from the snow inlet hole;
[0018] (2) The crushing device conducts preliminary crushing on the snow blocks in the miscellaneous snow. After crushing, the miscellaneous snow is conveyed to the grinding device through the conveying device. The grinding device grinds it through 3 spiral grinding shafts. After grinding the miscellaneous snow into powder, it flows into the snow discharge holes and is re-laid on the road surface. During the forward movement of the snow plow, the flattening device pre-flattens the snow falling out of the snow discharge holes through the convex plates on the periphery to ensure that the height of the snow is consistent, preparing for subsequent compaction and leveling.
[0019] The beneficial effects of the present invention are as follows:
[0020] 1. After collecting the miscellaneous snow, the present invention enters the box through the snow inlet hole. First, the crushing rod in the crushing device conducts preliminary periodic crushing to prevent large snow blocks from entering and blocking the subsequent processes. Then, it is conveyed to the grinding device through the conveyor belt for deep crushing to make the miscellaneous snow into powder. A multi-stage and specifically structured crushing method is adopted to ensure thorough treatment of the miscellaneous snow and guarantee uniform snow laying in the subsequent process.
[0021] 2. The transmission of the present invention is ingeniously coordinated. The crushing device and the conveying device are belt-driven to maintain the same operating speed, avoiding blockage of the snow inlet hole of the crushing device caused by too fast conveying. The grinding device and the flattening device are linked by gear meshing. When the grinding device works, it synchronously drives the flattening device to operate, simplifying the transmission link, improving the power transmission efficiency and system reliability. Moreover, the flattening device rotates driven by the gear mechanism to ensure the same flatness of the processed snow surface, providing a guarantee for the final compaction effect.
[0022] 3. The present invention adopts the modular design concept. Each functional component, such as the crushing device, the conveyor belt device, and the grinding device, works through connection methods such as belt and gear meshing, which is convenient for quick disassembly, installation, and maintenance when needed. This design not only reduces the maintenance difficulty and cost but also improves the flexibility and adaptability of the equipment. For example, in ski resorts of different scales or for different types of miscellaneous snow cleaning requirements, the most suitable snow-making vehicle configuration can be quickly customized by adding or reducing modules or adjusting the module combination method, greatly enhancing the versatility and practicality of the equipment.
