On large or small loaders, the driver will have a separate cab and the driving environment is controllable. However, on micro loaders, due to size reasons, the cab will be deleted to give the driver enough driving space. However, since the cab on the micro loader is removed, its driving environment is poor. How to improve the driving environment of micro-devices without cabs has become an urgent problem to be solved.

[0029] Example 1:

[0030] See also Figure 1 and Figure 2 The heat recovery mechanism of the mini loader of the present invention comprises:

[0031] A recovery assembly 3 is installed on the seat cushion inside the driver's seat 1 of the mini loader, and the recovery assembly 3 is connected to the exhaust pipe 21 of the diesel engine 2 through a connecting pipe 4;

[0032] The recovery assembly 3 includes a recovery plate 31, which has a cavity formed inside. The cavity is further divided into a plurality of transfer chambers 33 by a partition plate 32. The exhaust gas generated by the diesel engine 2 is passed through the transfer chambers 33 of the recovery plate 31 to recover the exhaust heat.

[0033] Each transfer cavity 33 of the recovery plate 31 is provided with an air inlet pipe 34 and an air outlet pipe 35. The air outlet pipe 35 on the transfer cavity 33 is connected with the air inlet pipe 34 on the adjacent transfer cavity 33, so that the air inlet pipe 34, the transfer cavity 33 and the air outlet pipe 35 form a ventilation circuit.

[0034] In this example:

[0035] The connecting pipe 4 in the recovery component 3 is connected to the end of the exhaust pipe 21 in the diesel engine 2. When the weather is cold, the exhaust of the diesel engine 2 still has a certain temperature after passing through the muffler 211. When the exhaust passes through the ventilation circuit formed by the intake pipe 34, the transfer chamber 33 and the outlet pipe 35, the heat will be exchanged to the recovery plate 31. When the recovery plate 31 absorbs the heat, it will change the temperature of the driving seat 1, thereby making the driving environment more comfortable for the driver.

[0036] Example 2:

[0037] See also Figure 3 As a further improvement of Example 1, the difference from Example 1 is that the air inlet pipe 34 and the air outlet pipe 35 are partially inserted into the transfer chamber 33, and one end of the air inlet pipe 34 and the air outlet pipe 35 located in the transfer chamber 33 is closed, and the surfaces of the air inlet pipe 34 and the air outlet pipe 35 located in the transfer chamber 33 are provided with silencer holes 37.

[0038] The starting end of the connecting pipe 4 is located on the exhaust pipe 21 between the diesel engine 2 and the muffler 211, and valves 5 are provided at the bottom of the connecting pipe 4 and the muffler 211. The connecting pipe 4 is also provided with a temperature detector 6 for detecting the temperature of the gas in the connecting pipe 4.

[0039] In this embodiment, the exhaust gas of the diesel engine 2 can be selectively diverted by the control of two valves 5. The exhaust gas entering the recovery assembly 3 is exchanged in the transfer chamber 33 through the silencer holes 37 on the intake pipe 34 and the outlet pipe 35, which can effectively eliminate the exhaust sound of the diesel engine 2. Therefore, the recovery assembly 3 not only has the function of improving the seat temperature, but also can eliminate the exhaust sound of the diesel engine 2 to a certain extent.

[0040] In this embodiment, when the exhaust temperature is too high due to the long-term operation of the diesel engine 2, the exhaust temperature entering the connecting pipe 4 will be detected by the temperature detector 6. Then, the detection data of the temperature detector 6 is processed by the control board, and a signal is sent to the valve 5 installed in the connecting pipe 4 to reduce the amount of gas entering the connecting pipe 4, thereby reducing the temperature that can be converted by the recovery plate 31, effectively ensuring that the recovery plate 31 heats the seat within a certain range.

[0041] Example 3:

[0042] See also Figure 4 As a further improvement to Example 1 or Example 2: the recovery component 3 also includes a heat dissipation unit 36 installed on the upper surface of the recovery plate 31, and an exchange membrane 361 that is laid around and fitted on the inner wall of the transfer cavity 33. The exchange membrane 361 partially protrudes from the recovery plate 31 and is connected to the heat dissipation unit 36.

[0043] The top of the recovery plate 31 corresponds to the transfer cavity 33 and is provided with a plurality of mounting holes 38 for the exchange membrane 361 to extend out of the recovery plate 31. The exchange membrane 361 located inside the mounting holes 38 is designed in a V-shaped wave shape to form a heat dissipation portion 362, which can effectively improve the efficiency of heat transfer by increasing the contact area.

[0044] The heat dissipation unit 36 is a heat dissipation plate 363 provided on the upper surface of the recovery plate 31 .

[0045] In this example:

[0046] The heat entering the transfer chamber 33 is transferred to the heat dissipation plate 363 through the exchange membrane 361, which can effectively transfer the heat upward and avoid the heat being wasted by the recovery plate 31.

[0047] In this embodiment, the exchange membrane 361 is preferably made of a material with high thermal conductivity, such as metal, and the recovery plate 31 is preferably made of a material with poor thermal conductivity.

[0048] Example 4:

[0049] See also Figure 5 As a further improvement of Example 3, the heat dissipation unit 36 includes a protective cover 364 installed on the edge of the mounting hole 38, the exchange membrane 361 located in the mounting hole 38 and the protective cover 364 form a heat dissipation cavity 365, and the top of the protective cover 364 is provided with a heat dissipation hole 366 for heat dissipation of the heat dissipation cavity 365.

[0050] The heat dissipation unit 36 further includes a heat dissipation air pump 7 . A heat dissipation pipe 71 is provided at the air outlet of the heat dissipation air pump 7 . The heat dissipation pipe 71 is connected to the heat dissipation cavity 365 through a plurality of branch pipes 72 .

[0051] This embodiment, when used:

[0052] The airflow generated by the heat dissipation air pump 7 can be transformed into warm air after passing through the heat dissipation cavity 365, and the warm air will diffuse toward the driver's seat 1 through the heat dissipation holes 366, thereby further improving the driving environment.

[0053] The above is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements based on the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
