Description

TECHNICAL FIELD

[0001] The utility model relates to the mechanical equipment field of soy sauce squeezing, specifically is a hovercraft. BACKGROUND

[0002] In the process of soy sauce brewing, it is usually necessary to separate soy sauce and soy sauce residue through a squeezing process, and the squeezing equipment (such as a squeezing cage) involved in this process needs to be precisely positioned and transported by a hovercraft. The working principle of the hovercraft is to spray compressed air onto the ground, generate a reaction force due to the obstruction of the ground, and thus make the hovercraft body float upward from the ground to form an air floating gap. Compared with the rolling friction and sliding friction between the tires of a traditional vehicle and the ground, the pressure air layer between the hovercraft and the ground produces smaller shear friction, enabling the hovercraft to be more flexible in turning and accurate in moving, and even to perform complex operations such as turning in place, and finally to place the heavy squeezing equipment accurately at the designated position in the process of soy sauce brewing.

[0003] In the prior art, the volume of soy sauce brewed at one time is usually in the order of thousands of liters or more, so the volume of the squeezing equipment involved in the squeezing process is usually large, and a large hovercraft is needed to transfer the equipment. In order to enable the hovercraft to have a large load capacity, a plurality of air cushion membranes are usually installed at the bottom of the hovercraft and a relatively complex gas pipeline is provided to ensure that the large hovercraft runs more stably. In order to ensure the normal production of large quantities of soy sauce and the normal operation of the large hovercraft, not only does the manufacturer need to have a sufficiently spacious production site, but also a large number of workers need to be arranged for on-site operation.

[0004] With the continuous diversification of soy sauce flavors in the market, there is a demand for small-scale production of soy sauce. If the above large-scale soy sauce squeezing equipment and hovercraft are continued to be used for small-batch soy sauce production, not only will a large amount of equipment energy consumption and personnel scheduling be generated, but also a certain degree of material waste will be caused. SUMMARY

[0005] In view of the above problems, the utility model provides a hovercraft for small-batch soy sauce squeezing, which can carry a small-sized squeezing equipment matched therewith and simultaneously transfer the carried equipment in a smaller production space.

[0006] The utility model provides a kind of air cushion vehicle, which is used to carry soy sauce squeezing equipment and can be transferred together with the carried equipment. The air cushion vehicle includes a vehicle body, only one air cushion film and a gas flow channel. The vehicle body includes an air inlet plate. The air cushion film is fixedly installed below the vehicle body. The air cushion film has a chamber inside. The bottom of the air cushion film has a plurality of evenly arranged air holes, which communicate the chamber with the outside. The gas flow channel is formed inside the air inlet plate in the form of holes punched in the air inlet plate. The gas flow channel includes an air inlet end and an air outlet end. The air inlet end communicates with the outside, and the air outlet end communicates with the chamber.

[0007] Optionally, the horizontal cross-section of the vehicle body is rectangular.

[0008] Optionally, the horizontal cross-section of the air cushion film is circular, and the air cushion film is arranged at the center of the vehicle body.

[0009] Optionally, the edge part of the air cushion film is fixedly connected to the vehicle body by a first pressing plate, and the center part of the air cushion film is fixedly connected to the vehicle body by a second pressing plate.

[0010] Optionally, a mounting plate is arranged between the vehicle body and the air cushion film.

[0011] Optionally, the air cushion vehicle further includes an oil receiving disc, which is arranged directly above the vehicle body. The top of the oil receiving disc has an opening part.

[0012] Optionally, the oil receiving disc includes a positioning member, which is arranged at the edge position where the inner side wall of the oil receiving disc meets the bottom surface.

[0013] Optionally, the air cushion vehicle further includes an oil outlet pipe, which is arranged at the outer bottom of the oil receiving disc. One end of the oil outlet pipe communicates with the inside of the oil receiving disc, and the other end communicates with the outside.

[0014] Optionally, a valve is arranged at the middle position of the oil outlet pipe, which can control the opening and closing of the pipeline of the oil outlet pipe.

[0015] Optionally, the air cushion vehicle further includes an air inlet pipe. One end of the air inlet pipe is fixedly connected to and communicates with the air inlet end of the gas flow channel, and the other end communicates with the outside.

[0016] By reducing the number of air cushion films installed in the air cushion vehicle and optimizing the structure of the gas flow channel inside the air cushion vehicle in the form of holes punched in the air inlet plate, the air cushion vehicle provided by the utility model has a smaller overall volume. It can be used to carry the squeezing equipment (such as squeezing cages, etc.) used in small-batch soy sauce production and can complete the transfer of the equipment in a limited space. The air cushion vehicle not only saves the consumption of compressed gas and other energy sources required during equipment transfer, but also has good use flexibility and convenience after being reduced in size to reduce the operation difficulty of on-site personnel and improve the production efficiency of small-batch soy sauce to a certain extent. In addition, the air cushion vehicle can also reduce the material loss that may occur during the soy sauce squeezing process. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] In the market of gradually diversified soy sauce flavors, in view of the miniaturized production demand of different types of soy sauce, the embodiment provides an air cushion car 100, which can be used to carry the pressing equipment (such as a pressing cage) used in small-batch soy sauce production; at the same time, the air cushion car 100 has the characteristics of small size, which has good use flexibility, and can complete soy sauce pressing and equipment transfer operations in limited space.

[0023] Compared with the large air cushion car 100 with multiple air cushion films 2, the air cushion car 100 in the embodiment includes a car body 1, only one air cushion film 2 and a gas flow channel 3, the length and width of the car body 1 are not more than 1m, so that the air cushion car 100 can better exert its strong use flexibility in various use environments, especially in smaller use spaces. Figure 1 and Figure 2When the air cushion vehicle 100 moves alone or after carrying the pressing equipment (not shown in the figure), in order to enable the air cushion vehicle 100 to keep a relatively stable running state, the horizontal section of the vehicle body 1 of the air cushion vehicle 100 in the utility model is rectangular, preferably, the horizontal section of the vehicle body 1 is square. Since in the small-scale soy sauce production, the input amount of raw materials and the output amount of soy sauce are relatively small, the weight limit requirement of the air cushion vehicle 100 is also correspondingly reduced, and the weight limit of the air cushion vehicle 100 is usually determined by the number of the air cushion membranes 2. Under the premise of ensuring that the weight limit of the air cushion vehicle 100 meets the corresponding requirements in the small-scale soy sauce pressing process, in order to minimize the volume of the air cushion vehicle 100, the air cushion vehicle 100 in the embodiment has only one air cushion membrane 2, which is fixedly installed below the vehicle body 1, and the air cushion membrane 2 is connected to the vehicle body 1 through the first pressing plate 5 and the second pressing plate 6. Figure 1 In order to enable the air cushion membrane 2 to be more firmly installed below the vehicle body 1, the edge part 21 of the air cushion membrane 2 is fixedly connected to the vehicle body 1 through the first pressing plate 5, and the center part 22 of the air cushion membrane 2 is fixedly connected to the vehicle body 1 through the second pressing plate 6. The first pressing plate 5 is a ring-shaped pressing plate, and a plurality of fixing holes are uniformly arranged along the ring-shaped circumference of the first pressing plate 5, and the second pressing plate 6 is a circular pressing plate, and a plurality of symmetrical fixing holes are arranged on the surface of the second pressing plate 6. By screwing the screws 7 into the fixing holes of the first pressing plate 5 and the second pressing plate 6 respectively, the screws 7 pass through the first pressing plate 5 or the second pressing plate 6 and the air cushion membrane 2 in sequence, and are finally screwed into the screw holes reserved on the lower surface of the vehicle body 1, so that the edge part 21 and the center part 22 of the air cushion membrane 2 are fixed below the vehicle body 1 through the first pressing plate 5 and the second pressing plate 6 respectively. In order to prevent the air cushion membrane 2 from being damaged during the fixing process, the mounting plate 12 with the same width as the diameter of the air cushion membrane 2 is arranged between the air cushion membrane 2 and the vehicle body 1, and the mounting plate 12 is fixed below the vehicle body 1 at the same time as the threaded connection between the first pressing plate 5 and the vehicle body 1 and the threaded connection between the second pressing plate 6 and the vehicle body 1 are completed.

[0024] In the embodiment, the air cushion membrane 2 has a cavity 23 inside, and the bottom of the air cushion membrane 2 has a plurality of uniformly arranged air holes, which communicate the cavity 23 with the outside. Figure 3 When the compressed gas in the outside is introduced into the cavity 23 of the air cushion membrane 2 and makes the air cushion membrane 2 expand to a gas-filled state, the gas in the cavity 23 will escape from the plurality of air holes (not shown in the figure) in the bottom of the air cushion membrane 2 to the ground outside until the gas pressure in the cavity 23 of the air cushion membrane 2 reaches a certain pressure value, the gas flow rate at the air holes increases, and the compressed gas ejected forms a pressure air layer between the bottom of the air cushion membrane 2 and the ground, so that the whole air cushion vehicle 100 rises, thereby reducing the friction between the air cushion vehicle 100 and the ground. At this time, the staff can easily transfer the air cushion vehicle 100.

[0025] In order to make the reaction force more uniform when the air holes at the bottom of the air cushion membrane 2 spray gas to the ground, and to make the movement of the air cushion vehicle 100 more stable when the air cushion vehicle 100 is used alone or is equipped with a pressing device, with reference to Figure 2 and Figure 3 In this embodiment, the horizontal section of the air cushion membrane 2 is circular and is arranged in the center of the vehicle body 1. Since the air holes at the bottom of the air cushion membrane 2 are uniformly arranged around the bottom of the air cushion membrane 2, the compressed gas sprayed to the ground will produce an upward reaction force on each position of the bottom of the air cushion membrane 2 after being blocked by the ground. With reference to Figure 3 In order to keep the air cushion vehicle 100 stable after being lifted, even when equipped with a pressing cage (not shown in the figure) and other devices, it can still lift the whole vehicle off the ground and move, the air holes in this embodiment can be arranged at the bottom of the side edge part 21, so that the spray direction of the compressed gas from the air holes to the outside is a downward diagonal direction towards the outer edge of the air cushion membrane 2.

[0026] In order to make the compressed air enter the chamber 23 of the air cushion membrane 2 smoothly, the air cushion vehicle 100 is provided with a gas flow channel 3, with reference to Figure 1 One side of the inside of the vehicle body 1 is provided with an air inlet plate 11, and the gas flow channel 3 is formed in the form of a hole in the air inlet plate 11 inside the air inlet plate 11, which includes an air inlet end 31 and an air outlet end 32, the air inlet end 31 is in communication with the outside, and the air outlet end 32 is in communication with the chamber 23. In order to ensure that the gas flow channel 3 can keep the air inlet stable when the compressed air in the outside enters the chamber 23 in the air cushion membrane 2, the air inlet plate 11 is preferably a stainless steel plate.

[0027] Compared with the prior art, the square tube is arranged inside the air cushion vehicle 100, and the channel in the square tube is used as the gas flow channel 3 of the air cushion vehicle 100. In the embodiment, the gas flow channel 3 is formed in the form of a hole in the stainless steel plate, which greatly reduces the equipment space required for arranging the gas flow channel 3 in the air cushion vehicle 100, thereby further reducing the overall volume of the air cushion vehicle 100. In addition, in order to improve the load limit, a large air cushion vehicle 100 is usually provided with multiple air cushion membranes 2, and in order to uniformly supply gas to the multiple air cushion membranes 2, a gas storage tank for buffering compressed gas is usually arranged inside the air cushion vehicle 100. Since the air cushion vehicle 100 provided by the embodiment only includes one air cushion membrane 2, it is not necessary to buffer and redistribute the compressed gas charged from the outside, thereby canceling the original gas storage tank arrangement in the air cushion vehicle 100. By arranging the gas flow channel 3 with a simpler structure inside the air cushion vehicle 100 and appropriately sizing the channel inner diameter of the gas flow channel 3, the air cushion vehicle 100 provided by the embodiment can also achieve simple buffering of the compressed gas charged from the outside and ensure smooth operation of the air cushion vehicle 100. In addition, the simple pipeline structure in the gas flow channel 3 can also reduce the loss of compressed gas to some extent, thereby further reducing the cost of soy sauce brewing.

[0028] In order to more conveniently charge compressed gas into the chamber 23 of the air cushion membrane 2, with reference to Figure 1 In the embodiment, the air cushion vehicle 100 further includes an air inlet pipe 4, one end of the air inlet pipe 4 is fixedly connected and communicated with the air inlet end 31 of the gas flow channel 3, and the other end is communicated with an air charging device (not shown in the figure) or a compressed gas source (not shown in the figure) outside, so that the compressed gas can be continuously and stably charged into the chamber 23 of the air cushion membrane 2, and the flow rate and air inlet amount of the compressed gas into the chamber 23 are set according to the specific load of the air cushion vehicle 100. When the air cushion vehicle 100 is used under the premise of reaching the load requirement, the embodiment can reduce the excessive inflow of compressed gas to avoid equipment damage and excessive gas loss.

[0029] In order to prevent the soy sauce generated by the pressing equipment such as the pressing cage during the pressing process from polluting the air cushion vehicle 100, in the embodiment, the vehicle body 1 of the air cushion vehicle 100 further includes an oil receiving disc 8. With reference to Figure 2 In order to ensure that the oil receiving disc 8 can be stably carried on the air cushion vehicle 100, the oil receiving disc 8 is arranged above the vehicle body 1, and preferably, the horizontal cross-sectional area of the oil receiving disc 8 is the same as that of the vehicle body 1. With reference to Figure 1The top of the oil receiving tray 8 has an opening 81. The soy sauce squeezing cage (not shown in the figure) can be hoisted above the air cushion vehicle 100, then slowly lowered and passed through the opening 81 of the oil receiving tray 8, and finally placed stably in the oil receiving tray 8 to perform soy sauce squeezing. To ensure that the squeezing cage can be quickly installed in the middle of the air cushion vehicle 100 during the process of entering the oil receiving tray 8, so that the air cushion vehicle 100 carrying the squeezing cage remains stable, the oil receiving tray 8 is also provided with positioning members 82. Referring to Figure 1 and Figure 2 The edges of the four inner side walls of the oil receiving tray 8 that meet the bottom surface are each provided with two positioning members 82 that are the same in shape and size, and each positioning member 82 includes a beveled edge portion 821 and a straight edge portion 822. When the squeezing cage is hoisted above the oil receiving tray 8 and begins to enter the oil receiving tray 8, the bottom edge of the squeezing cage first contacts the side of the beveled edge portion 821 of one or more positioning members 82 that faces the center of the oil receiving tray 8. As the hoisting position of the squeezing cage continues to drop, the bottom edge of the squeezing cage slides along the beveled edge of the beveled edge portion 821 to the side edge portion 822 that faces the center of the oil receiving tray 8. Because the distance between the straight edge portions 822 of the two symmetrically arranged positioning members 82 is the width of the squeezing cage, when the bottom surface of the squeezing cage is in full contact with the top surface of the oil receiving tray 8, the installation of the squeezing cage is completed and it is located in the middle of the oil receiving tray 8. At this time, even if the air cushion vehicle 100 is moved, the squeezing cage can still move relatively stably with the air cushion vehicle 100.

[0030] The height of the oil receiving tray 8 can be set according to the actual amount of soy sauce produced during the squeezing process. In this embodiment, when the squeezing cage is installed in the oil receiving tray 8, there is still enough space in the oil receiving tray 8 to store the squeezed soy sauce. In order to be able to discharge the soy sauce stored in the oil receiving tray 8 in time, the air cushion vehicle 100 in this embodiment is also provided with an oil outlet pipe 9. The oil outlet pipe 9 is arranged on the outside bottom of the oil receiving tray 8, one end of the oil outlet pipe 9 communicates with the inside of the oil receiving tray 8, and the other end communicates with the outside. At the same time, a valve 91 is arranged at the middle position of the oil outlet pipe 9, which can control the opening and closing of the pipeline of the oil outlet pipe 9. When the squeezing cage in the oil receiving tray 8 is in the process of soy sauce squeezing, the valve 91 in the oil outlet pipe 9 can be closed in advance, so that the squeezed soy sauce is stored in the oil receiving tray 8. Until the soy sauce in the oil receiving tray 8 reaches the preset capacity, the air cushion vehicle 100 is transferred to the next process position, and one end of the oil outlet pipe 9 is connected with other pipelines or equipment, then the valve 91 is opened, so that the soy sauce in the oil receiving tray 8 flows to the next process for treatment. If the oil receiving tray 8 of the air cushion vehicle 100 and other pipelines or equipment are always connected through the oil outlet pipe 9, the valve 91 of the oil outlet pipe 9 can also be kept in the open state all the time. When the squeezing cage squeezes the soy dregs in its interior, the squeezed soy sauce will be directly discharged from the oil receiving tray 8 and flow to other pipelines or equipment through the oil outlet, so as to be treated in the next process.

[0031] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
