Detailed implementation manners

[0022] The following takes the embodiments of the present invention as an inspiration. Through the following description, those of ordinary skill in the art can make various changes and modifications completely within the scope of the technical idea of the present invention without departing from it. The protection scope of the present invention is not limited to the content of the claims and the description.

[0023] The present invention will be further described with reference to the following drawings:

[0024] An agricultural machine with a double auxiliary starter includes an engine 100, a transmission 200 and a first auxiliary starter 300. The first auxiliary starter 300 is arranged on one side of the engine 100 and is connected to the starting shaft of the engine 100. It further includes a second auxiliary starter 400. The second auxiliary starter 400 is arranged on the other side of the transmission 200 relative to the first auxiliary starter 300. The second auxiliary starter 400 includes a drive mechanism 500, and the drive mechanism 500 is connected to the power shaft 210 of the transmission 200. When the second auxiliary starter 400 needs to be used, the drive mechanism 500 is started. Since the drive mechanism 500 is connected to the power shaft 210, the drive mechanism 500 drives the power shaft 210 to rotate, realizing the rotation of the transmission 200, and further realizing the operation of the engine 100 and the agricultural machine. In this way, it is achieved that the agricultural machine includes two auxiliary starters. When one of the auxiliary starters fails, the other auxiliary starter serves as a backup without affecting agricultural operations.

[0025] For the second auxiliary starter 400, the second auxiliary starter 400 can be any one of a hand-pulled disc auxiliary starter, a hand-crank starter, and an electric-start auxiliary starter.

[0026] When the second auxiliary starter 400 is a hand-pulled disc starter, the above-mentioned starting mechanism includes a cable, a pull disc, a transmission gear ring, etc. Since the hand-pulled disc starter is relatively common in the art, the specific structure of the hand-pulled disc will not be described in detail here.

[0027] The second auxiliary starter 400 can also be a hand-crank auxiliary starter or an electric-start auxiliary starter.

[0028] The driving mechanism 500 includes a pawl assembly 520. The pawl assembly 520 includes a pawl 521 and a pawl seat 522. A starting cup 510 is provided on the power shaft 210 of the transmission 200. The pawl assembly 520 is within the cup body of the starting cup 510. Pawl holes are provided on the cup body of the starting cup 510. When the pawl assembly 520 rotates, the pawl 521 is inserted into the pawl holes to drive the starting cup 510.

[0029] The hand-cranked main shaft stores energy through a spiral spring and then drives the rotation of the pawl assembly 520 to achieve the rotation of the starting cup 510, and further achieve the starting of the engine 100.

[0030] The power output shaft of the motor is connected to the pawl assembly 520. When the motor starts, it drives the rotation of the pawl assembly 520 to achieve the starting of the engine 100.

Threaded holes are provided on the power shaft 210, specifically, threaded holes are provided at one end of the power shaft 210 in the axial direction facing the second auxiliary starter 400. Screws are provided on the keyboard 600. The keyboard 600 is connected to the power shaft 210 through the screws to fix the starting cup 510 and the power shaft 210.

[0032] The keyboard 600 is connected to the power shaft 210 through the cooperation of a key and a keyway, including at least two cases. One is that the key is on the power shaft 210 and the keyway is on the keyboard 600. The other is that the key is on the keyboard 600 and the keyway is on the power shaft 210. The purpose is to connect the power shaft 210 and the keyboard 600 to achieve radial stability.

[0033] By providing threaded holes on the power shaft 210 and screws on the keyboard 600, the setting of the keyboard 600 and the screws here can be an integrated design. The keyboard 600 and the starting cup 510 can also be an integrated design, so that the keyboard 600 is provided at the bottom of the starting cup 510. The connection between the screw on the keyboard 600 and the threaded hole on the power shaft 210 makes the keyboard 600 and the power shaft 210 stable in the axial direction.

[0034] The keyboard 600 can also be a detachable keyboard, which is fixedly connected to the starting cup 510. Specifically, various connection methods such as bolt connection, screw connection, and snap connection between the detachable keyboard and the starting cup 510 can be selected. A power shaft hole 630 is provided on the detachable keyboard. After the power shaft 210 passes through the power shaft hole 630 of the detachable keyboard, the bolt 640 is connected to the threaded hole of the power shaft 210 through the power shaft hole 630. The detachable keyboard is arranged at the inner bottom and / or outer bottom of the starting cup 510, and there are three schemes: the detachable keyboard is arranged at the bottom inside the cup body of the starting cup 510; the detachable keyboard is arranged at the bottom outside the cup body of the starting cup 510; the detachable keyboard is arranged at both the bottom inside the cup body of the starting cup 510 and the bottom outside the cup body of the starting cup 510, that is, a detachable keyboard is arranged at both the bottom inside and outside the cup body of the starting cup 510 to achieve better fixation and stability of the starting cup 510.

[0035] The keyboard 600 includes a keyboard bottom 610 and an extension 620 with a boss structure. The extension 620 is provided with a power shaft hole 630 in the middle in order to match the power shaft 210, and a key or keyway for connecting with the power shaft 210 is arranged in the shaft hole. Since the power shaft 210 extends from the transmission 200, a seal 700 is provided to seal the transmission 200. The seal 700 includes a skeleton 710 and an elastic member 720. The skeleton 710 is a Z-shaped hollow disc 740, and the elastic member 720 is arranged inside the skeleton 710, and a power shaft hole 630 is arranged in the middle of the elastic member 720. By its Z-shape, it means the cross-section after the sectional view of the skeleton 710, presenting a Z-shape, and its disc refers to the disc formed by the Z-shaped cross-section 730 rotating 360 degrees around the center point of the skeleton 710. Its hollow structure is the mounting hole of the elastic member 720, and the elastic member 720 is also circular, and a power shaft hole 630 matching the circular cross-section of the power shaft 210 is arranged in the middle.

[0036] A sealing rubber ring 750 is arranged at the Z-shaped outer bending part of the seal 700.

[0037] A flange 800 is arranged between the transmission 200 and the second auxiliary starter 400. The flange 800 is fixedly arranged on the transmission 200 and is used to connect the second auxiliary starter 400.
