Description
Technical Field
[0001] This utility model relates to the field of air compressor technology, and in particular to a closed belt conveyor mesh cover structure and an air compressor. Background Technology
[0002] Air compressors, as a general-purpose air-powered device, are widely used in industrial production and routine maintenance. Among them, the method of using an electric motor to drive the compressor body through a belt drive mechanism has become a common technical solution due to its simple structure and smooth transmission.
[0003] To ensure operator safety and prevent foreign objects from being drawn into the transmission system, the belt drive mechanism of this type of air compressor is usually equipped with a metal mesh or plate-like protective cover.
[0004] However, during long-term use of the equipment, the timing belt will require regular inspection and replacement due to wear or aging, or the timing pulleys of different specifications may need to be replaced to adjust the transmission ratio according to production needs. In existing technologies, protective covers are often fixed to the machine body with multiple bolts. Maintenance personnel must loosen and remove all bolts one by one to remove the cover, and after maintenance, it must be repositioned and tightened again. The entire disassembly and assembly process is not only cumbersome and time-consuming, but also particularly inconvenient in confined working environments, greatly reducing the efficiency of maintenance.
[0005] Therefore, this utility model proposes a closed belt conveyor mesh cover structure and an air compressor to overcome the shortcomings of the prior art. Utility Model Content
[0006] In view of the problems in the existing technology where the protective cover of the belt drive mechanism of the air compressor is usually fixed with multiple bolts, the disassembly and assembly process is cumbersome and time-consuming, and the maintenance efficiency is low, this utility model aims to provide a closed belt conveyor mesh cover structure and air compressor with improved structure that can effectively solve the above problems.
[0007] This utility model provides a closed belt conveyor mesh cover structure and an air compressor, including a motor, a compressor body, a belt drive mechanism, and a mesh cover covering the outside of the belt drive mechanism; the belt drive mechanism includes a rotating shaft connected to the output end of the motor, a drive shaft connected to the input end of the compressor body, a second synchronous pulley fixed to the rotating shaft, a first synchronous pulley fixed to the drive shaft, and a synchronous belt sleeved on the first synchronous pulley and the second synchronous pulley.
[0008] The mesh cover includes an inner mesh cover, an outer mesh cover, and a third fixing bolt. The inner mesh cover is positioned outside the belt drive mechanism, and the outer mesh cover is positioned outside the inner mesh cover. An insert plate is fixedly connected to the inner wall of the outer mesh cover, and a slot is provided on the outer wall of the inner mesh cover to engage with the insert plate. This insertion structure allows the outer mesh cover to be quickly positioned and guided during installation. A through hole is provided on the outer mesh cover, and the third fixing bolt passes through the through hole and is detachably threaded to the inner mesh cover. By tightening or loosening the single third fixing bolt, the entire outer mesh cover can be quickly fixed or disassembled. Its structure is ingeniously combined and extremely convenient to operate.
[0009] Preferably, the enclosed belt conveyor mesh cover structure and air compressor further include a replacement component, which includes a first fixed plate, a second fixed plate, a first fixing bolt, and a second fixing bolt. The first synchronous pulley is detachably fixed to the outside of the first fixed plate by the second fixing bolt, and the first fixed plate is detachably fixed to the end of the drive shaft by the first fixing bolt. The second synchronous pulley is detachably fixed to the outside of the second fixed plate by the second fixing bolt, and the second fixed plate is detachably fixed to the end of the shaft by the first fixing bolt. This structural design allows users to easily replace synchronous pulleys of different diameters to achieve flexible adjustment of the transmission ratio.
[0010] Preferably, the enclosed belt conveyor mesh cover structure and air compressor further include a filter assembly fixedly connected to the air inlet end of the compressor body; further, the filter assembly includes an air inlet pipe, and a first filter screen, a second filter screen and a third filter screen are fixedly connected sequentially along the airflow direction inside the air inlet pipe, and the filter apertures of the first filter screen, the second filter screen and the third filter screen decrease sequentially. This multi-stage filtration structure can effectively filter out impurities of different sizes in the intake air, thereby better protecting the internal components of the compressor body.
[0011] Preferably, the enclosed belt conveyor mesh cover structure and air compressor further include an air storage tank. The air outlet of the compressor body is connected to the air storage tank through an air delivery pipe for storing and stably outputting compressed air. An air outlet valve for delivering compressed air is also connected to the end of the air storage tank.
[0012] Preferably, to facilitate the movement and deployment of the entire machine, rollers are fixedly connected to the bottom of the gas storage tank, and a push handle is fixedly connected to one end of the device.
[0013] Preferably, the enclosed belt conveyor mesh cover structure and air compressor also include a controller for controlling the start and stop of the motor, so as to realize centralized and convenient operation of the equipment.
[0014] This utility model has the following beneficial effects: 1. This utility model, by setting a double-layer structure consisting of an inner mesh cover and an outer mesh cover, and setting an insert plate in the outer mesh cover and opening a slot in the inner mesh cover, achieves connection by inserting and locking with a single bolt, which solves the problem that the protective cover in the prior art usually uses multiple bolts for fixing, which is cumbersome to disassemble and assemble and has low maintenance efficiency. It achieves the beneficial effects of quick disassembly and assembly, convenient maintenance and saving time.
[0015] 2. This utility model, by setting a replaceable synchronous pulley assembly, allows users to replace the first and second synchronous pulleys of different diameters as needed. This solves the problem that the traditional air compressor has a fixed transmission ratio and cannot adapt to the diverse needs of different air usage scenarios for exhaust volume and output pressure. It achieves the beneficial effects of flexibly adjusting equipment performance, optimizing energy consumption, and expanding the applicability of the equipment.
[0016] 3. This utility model solves the problem that impurities of different sizes in the air can easily enter the compressor body and cause wear on internal precision components by setting multiple layers of filter screens with progressively smaller filter diameters in the air intake pipe. It achieves efficient filtration of intake air at each stage, effectively protects the core components of the compressor, and extends the service life of the equipment. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0020] Example: Please refer to Figures 1 to 5 This utility model provides a closed belt conveyor mesh cover structure and an air compressor, which aims to solve the problem that the belt drive protective cover of the air compressor in the prior art is usually fixed with multiple bolts, which makes the structure cumbersome to disassemble and assemble, resulting in inconvenient maintenance and low efficiency.
[0021] like Figure 1 As shown, the enclosed belt conveyor mesh cover structure and air compressor include a motor 5, a compressor body 6, and a belt drive mechanism for connecting the motor 5 and the compressor body 6. A mesh cover is provided on the outside of the belt drive mechanism to provide enclosed protection for the belt drive mechanism. The belt drive mechanism includes a rotating shaft 19 connected to the output end of the motor 5, a drive shaft 18 connected to the input end of the compressor body 6, a second synchronous pulley 16 fixed to the rotating shaft 19, a first synchronous pulley 15 fixed to the drive shaft 18, and a synchronous belt 17 sleeved on the first synchronous pulley 15 and the second synchronous pulley 16.
[0022] Reference Figure 2 , Figure 3 and Figure 5The structure of the mesh cover includes an inner mesh cover 12, an outer mesh cover 11, and a third fixing bolt 13. The inner mesh cover 12 is installed on the outside of the belt drive mechanism, and the outer mesh cover 11 is detachably installed on the outside of the inner mesh cover 12 to form a double-layer protective structure. For easy assembly and disassembly, an insert plate 20 is fixedly connected to the inner wall of the outer mesh cover 11, and a slot 14 for engaging with the insert plate 20 is provided on the outer wall of the inner mesh cover 12. A through hole is provided on the outer mesh cover 11, and the third fixing bolt 13 passes through the through hole and is detachably threaded to the inner mesh cover 12. During installation, the insert plate 20 on the outer mesh cover 11 is aligned and inserted into the slot 14 of the inner mesh cover 12 for initial positioning, and then the third fixing bolt 13 is screwed in and locked. Disassembly is performed in reverse. This structure achieves extremely quick and convenient assembly and separation between the outer mesh cover 11 and the inner mesh cover 12 through the positioning of the insert plate 20 and the slot 14 and the single-point locking of the third fixing bolt 13.
[0023] To enable flexible adjustment of the transmission ratio to adapt to different working conditions, the enclosed belt conveyor mesh cover structure and air compressor also include a replacement component 9, which forms a specific detachable connection relationship with the first synchronous pulley 15, the second synchronous pulley 16, the drive shaft 18 and the rotating shaft 19.
[0024] Please refer to the following carefully. Figure 1 and Figure 3 The following is a detailed description of the structure of the replacement component 9: The replacement component 9 includes a first fixing plate 901, a second fixing plate 904, a first fixing bolt 902, and a second fixing bolt 903. This replacement component 9 is used to indirectly fix the first synchronous pulley 15 to the drive shaft 18 and the second synchronous pulley 16 to the rotating shaft 19. Specifically, the first synchronous pulley 15 is detachably fixed to the outside of the first fixing plate 901 by the second fixing bolt 903, while the first fixing plate 901 is detachably fixed to the end of the drive shaft 18 by the first fixing bolt 902. Similarly, the second synchronous pulley 16 is detachably fixed to the outside of the drive shaft 18 by the second fixing bolt 903. Bolt 903 is detachably fixed to the outside of the second fixed plate 904, which is detachably fixed to the end of the rotating shaft 19 by the first fixing bolt 902. When the synchronous pulley needs to be replaced, the operator can remove the corresponding first fixing bolt 902 and second fixing bolt 903 in sequence after removing the outer mesh cover 11, so as to easily remove and replace the first synchronous pulley 15 and the second synchronous pulley 16. This structure design allows users to easily replace the first synchronous pulley 15 and the second synchronous pulley 16 with different diameters, thereby adjusting the transmission ratio of the belt drive mechanism.

[0026] Please refer to the following carefully. Figure 1 and Figure 3 The following is a detailed description of the structure of the replacement component 9: The replacement component 9 includes a first fixing plate 901, a second fixing plate 904, a first fixing bolt 902, and a second fixing bolt 903. This replacement component 9 is used to indirectly fix the first synchronous pulley 15 to the drive shaft 18 and the second synchronous pulley 16 to the rotating shaft 19.

Bolt 903 is detachably fixed to the outside of the second fixed plate 904, which is detachably fixed to the end of the rotating shaft 19 by the first fixing bolt 902.

This structure design allows users to easily replace the first synchronous pulley 15 and the second synchronous pulley 16 with different diameters, thereby adjusting the transmission ratio of the belt drive mechanism.
[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to purify the air entering the compressor body 6 and protect its internal structure, the air compressor further includes a filter assembly 7 fixedly connected to the air inlet end of the compressor body 6; see reference. Figure 4 The filter assembly 7 specifically includes an air inlet pipe 701, and a first filter screen 702, a second filter screen 703 and a third filter screen 704 are fixedly connected in sequence along the airflow direction inside the air inlet pipe 701; in order to achieve efficient step-by-step filtration, the filter diameters of the first filter screen 702, the second filter screen 703 and the third filter screen 704 decrease in sequence. As another preferred embodiment, in order to store compressed air and output it on demand, the air compressor also includes an air storage tank 1. The air outlet end of the compressor body 6 is connected to the air storage tank 1 through an air supply pipe 10, and an air outlet valve 3 for delivering compressed air is connected to the end of the air storage tank 1. To facilitate the movement and deployment of the equipment at the work site, a roller 2 is fixedly connected to the bottom of the air storage tank 1, and a push handle 4 is fixedly connected to one end of the device. In addition, to achieve convenient operation of the entire device, a controller 8 for controlling the start and stop of the motor 5 is also included.
[0028] The working principle of the enclosed belt conveyor mesh cover structure and air compressor of this utility model is as follows: When the equipment is needed, the operator can push it with the push handle 4 and use the rollers 2 to move the device to the work point. The motor 5 is started by the controller 8, and the shaft 19 of the motor 5 starts to rotate, which in turn drives the second synchronous pulley 16 fixed on the shaft 19 to rotate. The synchronous belt 17 sleeved on the second synchronous pulley 16 and the first synchronous pulley 15 moves accordingly and transmits power to the first synchronous pulley 15. The first synchronous pulley 15 then drives the transmission shaft 18 connected to it to rotate, thereby driving the compressor body 6 to start working.
[0029] When the compressor body 6 is working and draws in air from the outside, the air first enters the intake pipe 701 of the filter assembly 7. Inside the intake pipe 701, the air passes through the first filter screen 702, the second filter screen 703 and the third filter screen 704 with filter diameters decreasing from large to small in sequence. Impurities in the air are filtered out step by step, and the clean air enters the compressor body 6. The high-temperature and high-pressure air compressed by the compressor body 6 is transported to the air storage tank 1 through the air delivery pipe 10 for storage and cooling, and finally the compressed air is stably supplied to the outside through the air outlet valve 3.
[0030] When maintenance or replacement of the synchronous pulleys is required to adjust the transmission ratio of the belt drive mechanism, the operator only needs to loosen and remove the third fixing bolt 13 to pull the outer mesh cover 11 outward, so that the insert plate 20 on it disengages from the slot 14 of the inner mesh cover 12, thereby quickly removing the outer mesh cover 11 and exposing the internal belt drive mechanism. Subsequently, by disassembling and replacing the first fixing bolt 902 and the second fixing bolt 903 in the replacement assembly 9, the first synchronous pulley 15 and the second synchronous pulley 16 can be easily removed and replaced from the drive shaft 18 and the rotating shaft 19. This series of designs greatly simplifies the disassembly and assembly steps and solves the problems of cumbersome disassembly and assembly and low maintenance efficiency of the protective cover in the prior art.
[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
