[0029] The first connecting rod 201 is arranged inside the shell 101 and passes through the rib 102 for rotational connection. The end of the first connecting rod 201 is fixedly connected to the rotating arm 202, and the end of the rotating arm 202 is rotatably clamped with the execution connecting rod 202a; when the first connecting rod 201 rotates, the rotating arm 202 is rotated, and the degree of throttle closing is controlled by the rotation angle of the rotating arm 202.
[0030] The manual-automatic conversion handle 401a is rotatably connected to the outer wall of the shell 101, and the fourth connecting rod 401 is movably connected to the bottom of the manual-automatic conversion handle 401a. The outer wall of the fourth connecting rod 401 is fixedly connected to the manual-automatic conversion intermediate wheel 401b, and the outer wall of the first connecting rod 201 is fixedly connected to the main shaft output gear 201a, and the main shaft output gear 201a is meshed with the manual-automatic conversion intermediate wheel 401b; when the first connecting rod 201 rotates, the fourth connecting rod 401 rotates through the meshing of the main shaft output gear 201a and the manual-automatic conversion intermediate wheel 401b.
[0031] The conversion locking pin 402 is slidably connected to the outer wall of the shell 101. When the conversion locking pin 402 slides to the end of the outer wall of the shell 101, the manual-automatic conversion handle 401a and the outer wall of the conversion locking pin 402 are engaged, and the manual-automatic conversion handle 401a and the fourth connecting rod 401 are both in a fixed state; since the fourth connecting rod 401 and the manual-automatic conversion handle 401a are movably connected, the height of the manual-automatic switching intermediate wheel 401b is controlled by controlling the movable fourth connecting rod 401, and whether it is engaged with the main shaft output gear 201a is controlled, thereby achieving the control of whether the first connecting rod 201 and the fourth connecting rod 401 are in a linked state, and by controlling the linked state of the first connecting rod 201 and the fourth connecting rod 401, whether the throttle adjustment mechanism is automatic or manual is controlled.
[0032] The automatic adjustment servo motor 311 is arranged to penetrate the outer wall of the shell 101, and the automatic adjustment main transmission gear 311a is arranged at the rotating shaft at the end of the automatic adjustment servo motor 311, and the automatic adjustment main transmission gear 311a is meshed with the main shaft output gear 201a; when the throttle adjustment mechanism is in the automatic state, the rotating shaft at the end of the automatic adjustment servo motor 311 rotates, and the meshing of the automatic adjustment main transmission gear 311a and the main shaft output gear 201a makes the first connecting rod 201 rotate, thereby controlling the closing degree of the throttle.
[0033] The rotary damper 301a-1 is rotatably connected to the inner wall of the shell 101, the manual adjustment wheel 301a is fixedly connected to the second connecting rod 301, the second connecting rod 301 passes through the rotary damper 301a-1 and is rotatably connected to the inner wall of the shell 101 through the rotary damper 301a-1, the outer wall of the second connecting rod 301 is fixedly connected with a manual adjustment worm 301a-2, the third connecting rod 302 is rotatably connected to a plurality of groups of ribs 102, the outer wall of the third connecting rod 302 is fixedly connected with a manual adjustment turbine 302a, the manual adjustment worm 301a-2 and the manual adjustment turbine 302a are meshed with each other; when the throttle adjustment mechanism is in the manual control state, in this state The automatic adjustment servo motor 311 is in the off state, and the rotating manual adjustment wheel 301a causes the third connecting rod 302 and the manually adjustable main transmission gear 302b to rotate through the manual adjustment wheel 301a and the manually adjustable worm 301a-2. At this time, the manually adjustable main transmission gear 302b is mutually transmitted with the main shaft output gear 201a through the manual automatic replacement intermediate wheel 401b to control the rotation angle of the first connecting rod 201, so as to control the closing degree of the throttle adjustment mechanism. The role of the rotating damper 301a-1 is to increase the manual adjustment wheel 301a to prevent the vibration of the diesel engine from causing the manual adjustment wheel 301a to move freely and change the position of the rotating arm 202.
[0034] A manually adjustable main transmission gear 302b is fixedly connected to the bottom of the outer wall of the third connecting rod 302, and the manually adjustable main transmission gear 302b is meshed with the manual-automatic conversion intermediate gear 401b.
[0035] The housing 101 is located at one end of the outer wall of the rotating arm 202 and is fixedly connected with an adjustment dial 501, and the outer wall of the actuator link 202a is provided with an angle scale; the function of the adjustment dial 501 is to facilitate the operator to have a more accurate observation of the closing degree of the throttle.
[0036] In the interlayer where the rotating arm 202 is located and the rib plate 102 are located, both ends of the inner wall of the rib plate 102 are rotatably clamped with non-circular limit rotating blocks 502; by rotating the two sets of non-circular limit rotating blocks 502, the rotatable angle of the rotating arm 202 is limited, and the maximum oil supply of the throttle is further limited.
[0037] Among them, the automatic adjustment of the servo motor 311 is a very mature existing technology in real life, so it will not be described here in detail.

[0040] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
