Description

Technical Field

[0001] This invention belongs to the field of robot design and automation, and particularly relates to a robot device with a helical propulsion structure and functions of stirring and collecting salt, which is suitable for complex environments such as salt fields that are corrosive, muddy, and shallow. Background Technology

[0002] In traditional salt field operations, the processes of stirring and collecting salt are mainly done manually, which is labor-intensive, inefficient, and the prolonged exposure to highly alkaline brine can easily damage the health of workers. With the development of efficient land use methods such as integrated photovoltaic power generation in salt fields, traditional manual operation modes also face problems such as limited physical space, and there is an urgent need to design an automated device that can operate stably in the special environment of salt fields.

[0003] As a highly adaptable all-terrain propulsion method, spiral propulsion technology has good passability, but its integration with salt-stirring function and the overall design for adaptability in highly corrosive and shallow water environments are still lacking. Summary of the Invention

[0004] This invention aims to solve the problems of high manual labor intensity, low efficiency of salt mud mixing, and severe equipment corrosion and damage in traditional salt field operations. It proposes a spiral propulsion robot device with a compact structure, integrated functions, and suitable for the special environment of salt fields. The robot integrates propulsion, mixing, material collection, material lifting and separation functions, and has good operational stability and environmental adaptability.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a spiral propulsion robot suitable for salt field environments, comprising a spiral propulsion mechanism, a spiral material collection device, a spiral material lifting device, a collection bin, a filter screen, and electrical and protective structures.

[0006] The spiral propulsion mechanism includes two symmetrically arranged spiral propulsion wheels. Each propulsion wheel is equipped with a 31.8° spiral angle blade and a 30° conical guide structure, which can provide strong propulsion in muddy or brine environments, while also stirring the salt mud and effectively improving crystallization efficiency.

[0007] The spiral collecting device is arranged on both sides of the front of the vehicle body. It uses the spiral groove structure to laterally concentrate the dispersed salt mud to the central axis of the vehicle body, which is convenient for subsequent unified processing.

[0008] The spiral lifting device is located at the center of the robot and adopts a single-stage spiral tube design. It is driven by a DC motor to vertically transport the collected salt mud to the upper collection bin.

[0009] The collection bin is located above the vehicle body and is used to collect the salt crystal products conveyed by the lifting system for easy subsequent transfer.

[0010] The filter screen has a pore size of 2-5 mm and is used to effectively separate brine from solid salt crystals.

[0011] The electrical and protective structure, namely all motors, batteries, controllers, etc., is located in a sealed housing. The housing is made of aluminum alloy and treated with nickel-phosphorus chemical plating. The gaps between the housings are sealed with silicone to ensure corrosion and water resistance.

[0012] The beneficial effects of this invention are as follows:

[0013] This invention integrates structures such as spiral propulsion, material collection, material lifting, and filtrate separation to achieve automated salt mud mixing and collection operations in the muddy and highly corrosive environment of salt fields. It has beneficial effects such as integrated propulsion and mixing functions, mechanized operation process, strong anti-corrosion and waterproof capabilities, wide adaptability, and high maintainability. It significantly improves the efficiency of salt field operations and reduces labor costs, and has good engineering application prospects and industrial promotion value. Attached Figure Description
