Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering and automation control technology, and specifically relates to a windbreak door opening mechanism. Background Technology

[0002] The engine choke is an important component of a carburetor gasoline engine. Its primary function during cold starts is to increase the fuel-air mixture concentration by partially closing the intake passage, thereby improving engine starting performance. Traditionally, operators manually adjust the choke opening using a control lever or pull button. In certain environments, such as extreme cold weather or when remote monitoring and operation are required, remote control of the choke may be necessary to optimize starting performance and ease of operation. However, due to current technological limitations, most traditional carburetor engines do not support remote choke control. This typically involves direct mechanical operation, making electronic or remote control difficult. Therefore, in these situations, users still rely on the traditional manual adjustment method.

[0003] In the existing technology, when the engine is used for the spray pump, the operator is often far away from the main unit when using the spray pump, and needs to remotely control the choke and start the engine, but traditional engines cannot be operated remotely. Utility Model Content

[0004] The purpose of this utility model is to provide a choke opening mechanism, which aims to solve the problem in the prior art that when the engine is used for the spray pump, the operator is often far away from the main unit and needs to remotely control the choke and start the engine, while traditional engines cannot be operated remotely.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A windbreak door opening mechanism includes:

[0007] Engine body;

[0008] The control mechanism includes a control torque, a connecting block, a linkage rod, and an electromagnetic pull rod. The control torque is rotatably connected to the engine body and is also connected to an assembly that controls the choke switch inside the engine body. The connecting block is fixedly connected to the surface of the control torque. One end of the linkage rod is rotatably connected to the connecting block. The electromagnetic pull rod is fixedly connected to the surface of the engine body, and the other end of the linkage rod is rotatably connected to the output end of the electromagnetic pull rod.

[0009] A pull-back assembly is disposed on one side of the electromagnetic pull rod.

[0010] In a preferred embodiment of this utility model, the pull-back assembly includes a baffle and a spring. The baffle is fixedly connected to the circumferential surface of the output end of the electromagnetic pull rod, and the spring is sleeved on the circumferential surface of the output end of the baffle. One end of the spring is fixedly connected to the surface of the baffle, and the other end is fixedly connected to the surface of the electromagnetic pull rod.

[0011] As a preferred embodiment of this utility model, an indicator block is fixedly connected to the circumferential surface of the control knob.

[0012] In a preferred embodiment of this utility model, a signal receiving and control processor is fixedly connected to the surface of the engine body, and the signal receiving and control processor is signal connected to the engine body and the electromagnetic pull rod.

[0013] In a preferred embodiment of this utility model, a base plate is fixedly connected to the surface of the engine body, and a power source is fixedly connected to the surface of the base plate. The power source is electrically connected to the signal receiving and control processor and the electromagnetic pull rod.

[0014] As a preferred embodiment of this utility model, the surface of the base plate is provided with multiple mounting holes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this solution, when the engine is used to drive the spray pump, if the operator is far away from the main unit, they can send a command to the signal receiving control processor via remote control. The system is responsible for controlling the operation of the engine body and the electromagnetic lever. The electromagnetic lever extends and retracts according to the command. By pulling the linkage rod, the connecting block rotates, thereby controlling the torsional movement of the choke switch. This achieves remote control of the opening and closing of the choke. In this way, even if the operator is far away from the engine, they can easily adjust the choke state and the operation of the engine body, and optimize the engine's performance under different working conditions.

[0017] 2. In this solution, when the electromagnetic pull rod is de-energized, its output end will be pulled back under the elastic force of the spring. This action will drive the control twisting motion responsible for controlling the choke switch, thereby achieving the choke closing. This mechanism can automatically close the choke when the equipment is not working, effectively preventing dust and other foreign objects from entering the engine and protecting the engine from pollution and potential damage.

[0024] Example

[0025] Please see Figures 1-3 The present invention provides the following technical solution:

[0026] A windbreak door opening mechanism includes:

[0027] Engine body 1;

[0028] The control mechanism includes a control torque 5, a connecting block 7, a linkage rod 8, and an electromagnetic pull rod 9. The control torque 5 is rotatably connected to the engine body 1 and is also connected to the assembly that controls the choke switch inside the engine body 1. The connecting block 7 is fixedly connected to the surface of the control torque 5. One end of the linkage rod 8 is rotatably connected to the connecting block 7. The electromagnetic pull rod 9 is fixedly connected to the surface of the engine body 1, and the other end of the linkage rod 8 is rotatably connected to the output end of the electromagnetic pull rod 9.

[0029] The pull-back assembly is located on one side of the electromagnetic pull rod 9.

[0030] In a specific embodiment of this utility model, the output end of the electromagnetic pull rod 9 is extended or retracted by operating it. At this time, the connecting rod 8 will be pulled, and the connecting rod 8 will drive the connecting block 7 to rotate, thereby controlling the control torque 5 to rotate, thereby controlling the operation of the components of the windbreak switch to realize the control of the windbreak switch.

[0031] Please refer to the details. Figures 1-3The pull-back assembly includes a baffle 10 and a spring 11. The baffle 10 is fixedly connected to the circumferential surface of the output end of the electromagnetic pull rod 9. The spring 11 is sleeved on the circumferential surface of the output end of the baffle 10, and one end of the spring 11 is fixedly connected to the surface of the baffle 10, while the other end is fixedly connected to the surface of the electromagnetic pull rod 9.

[0032] In this embodiment: when the electromagnetic lever 9 is de-energized, the output end of the electromagnetic lever 9 is pulled back under the action of the spring 11, thereby driving the control torque 5 to rotate, thus closing the windbreak door.

[0033] Please refer to the details. Figures 1-3 An indicator block 6 is fixedly connected to the circumferential surface of the control torque 5.

[0034] In this embodiment: when the control knob 5 rotates, the indicator block 6 will also rotate, so the opening and closing of the air choke can be determined by the direction of the indicator block 6.

[0035] Please refer to the details. Figures 1-3 A signal receiving and control processor 2 is fixedly connected to the surface of the engine body 1, and the signal receiving and control processor 2 is signal connected to the engine body 1 and the electromagnetic lever 9.

[0036] In this embodiment, the signal receiving and control processor 2 is connected to the engine body 1 and the electromagnetic lever 9 so that the signal receiving and control processor 2 can be instructed by a remote control, and then the signal receiving and control processor 2 can control the operation of the electromagnetic lever 9 and the operation of the engine body 1.

[0037] Please refer to the details. Figures 1-3 A base plate 4 is fixedly connected to the surface of the engine body 1, and a power supply 3 is fixedly connected to the surface of the base plate 4. The power supply 3 is electrically connected to the signal receiving and control processor 2 and the electromagnetic pull rod 9.

[0038] In this embodiment, the power supply 3 is electrically connected to the signal receiving control processor 2 and the electromagnetic lever 9 in order to supply power to the signal receiving control processor 2 and the electromagnetic lever 9.

[0039] Please refer to the details. Figures 1-3 The surface of the base plate 4 has multiple mounting holes.

[0040] In this embodiment, the surface of the base plate 4 is provided with multiple mounting holes to facilitate the installation of the device in the required position via the mounting holes and bolts.

[0041] It should be noted that the specific model of engine body 1, signal receiving and control processor 2, power supply 3, and electromagnetic lever 9 used shall be selected by those skilled in the art. Furthermore, the engine body 1, signal receiving and control processor 2, power supply 3, and electromagnetic lever 9 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0042] The working principle and usage process of this utility model are as follows: When the engine is used in a spray pump, the operator, while using the spray pump and being far from the main unit, issues commands to the signal receiving and control processor 2 via a remote control. The signal receiving and control processor 2 then controls the operation of the electromagnetic lever 9 and the engine body 1. By operating the electromagnetic lever 9, its output end is extended or retracted. At this time, the connecting rod 8 is pulled, which drives the connecting block 7 to rotate, thereby controlling the control torque 5 to rotate. This controls the operation of the choke switch assembly, thus controlling the choke switch. When the electromagnetic lever 9 is de-energized, its output end is pulled back under the elastic force of the spring 11, thereby driving the control torque 5 to rotate, thus closing the choke and preventing dust and other foreign objects from entering the engine. This solves the problem that when the engine is used in a spray pump, the operator is often far from the main unit and needs to remotely control the choke and start the engine, while traditional engines cannot be remotely operated.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
