Technical Field
[0001] The utility model relates to the technical field of forklift parts, in particular to a sinking type air intake mechanism. Background Art
[0002] The intake system is an important part of the forklift. It is mainly used to introduce air or mixed gas into the cylinder of the engine. The layout and installation of the intake system directly affect the stability and reliability of the engine operation. The intake duct is the main component of the intake system. It is connected to the air filter and introduces the gas into the air filter. After filtering and evolving through the filter, it can make the other gases used for engine operation purer and increase its stability.
[0003] The existing air intake mechanism on the market directly fixes the air filter through the fixing mechanism inside the forklift. It is a high-position installation, which is relatively convenient to install and disassemble. However, in actual use, the high-position installation method will cause excessive resistance to the air intake, and there are certain restrictions on the length and cross-sectional area of the air intake pipe. For this reason, we proposed a sunken air intake mechanism. Utility Model Content

[0012] In summary, the utility model mainly has the following beneficial effects:
[0013] 1. The design of the air filter can be used as the main filtering device of the air intake mechanism to ensure the purity and safety of the intake air. The design of the air filter mounting bracket can realize the low-position installation of the device body. Compared with the traditional high-position air intake, the air intake channel of the device is shortened and is not limited by the cross-sectional area of the pipeline. At the same time, the air intake volume will increase, effectively reducing the intake resistance;
[0014] 2. Through the design of the second intake pipe, it can cooperate with the grid-shaped intake device on the side of the vehicle body side cover to ensure that under the premise of low-position installation, the pipe can still have sufficient length to buffer the inhaled gas, avoiding excessive impact when the gas is inhaled, which will affect the stability of the engine operation.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] refer to Figure 1-Figure 3 The downward air intake mechanism comprises a vehicle body 10, wherein an air filter mounting bracket 6 is arranged inside the vehicle body 10. The design of the air filter mounting bracket 6 enables the low-position installation of the device body. Compared with the traditional high-position air intake, the air intake channel of the device is shortened and is not limited by the cross-sectional area of the pipeline. At the same time, the air intake volume is increased, and the air intake resistance is effectively reduced. A connecting block 11 is arranged on the top surface of the air filter mounting bracket 6, and an air filter 2 is fixedly mounted on the top surface of the connecting block 11. The design of the air filter 2 enables the air filter 2 to be used as the most important filtering device of the air intake mechanism to ensure the purity and safety of the intake air.
[0021] The material of the air filter mounting bracket 6 is Q235A carbon steel. The air filter mounting bracket 6 is composed of a connecting plate inclined with the vertical direction, a horizontal plate at the top and a fixing plate perpendicular to the connecting plate at the bottom. The design of the air filter mounting bracket 6 and the high toughness and plasticity of the material make the device have higher stability, so that the device can withstand greater force during actual operation. The bottom surface of the horizontal plate part of the air filter mounting bracket 6 and the top surface of the fixing plate part are provided with a plurality of threaded holes. The internal threads of the threaded holes are connected with bolts 9. The air filter mounting bracket 6 is connected with bolts 9 through the threaded holes. The bolt 9 is fixedly installed with the vehicle body 10, and the connecting block 11 is fixedly installed with the air filter mounting bracket 6 through the bolt 9. The interior of the threaded hole is provided with a first washer 7, and the interior of the threaded hole is provided with a second washer 8. Through the design of the bolt 9, the connecting block 11 can be installed with other devices. Through the design of the first washer 7 and the second washer 8, the stability during installation can be increased, and the probability of instability of the device caused by thread slippage can be reduced. A second intake pipe 3 is provided on one side of the air filter 2, and a first intake pipe 1 is provided on one side of the air filter 2. The design of the air pipe 1 and the second air intake pipe 3 can respectively serve as two parts of the device that are connected to the outside world. By selecting the specifications of the first air intake pipe 1 and the second air intake pipe 3, the air intake volume of the device can be adjusted, so that the device is suitable for different scenes. The second air intake pipe 3 is composed of a horizontal pipe and arc-shaped curved pipes connected thereto at both ends. Through the design of the second air intake pipe 3, the grid design of the air intake part on the side cover of the vehicle body 10 can be used to ensure that the pipe has enough length to buffer the inhaled gas under the premise of low-position installation, so as to avoid excessive impact when the gas is inhaled. In order to affect the stability of engine operation, the outer wall surfaces of the first intake pipe 1 and the second intake pipe 3 are both sleeved with a second throat hoop 5, and the first intake pipe 1 and the second intake pipe 3 are both fixedly installed on one side of the air filter 2 through the second throat hoop 5, and the first throat hoop 4 is fixedly installed on the end of the second intake pipe 3 away from the second throat hoop 5. Through the design of the second throat hoop 5 and the first throat hoop 4, the connection between the second intake pipe 3 and the first throat hoop 4 and the air filter 2 can be made tighter, and at the same time, it will be more stable when the second intake pipe 3 is connected to other pipelines.
