DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-5 The utility model provides a technical solution: a traction device for agricultural machinery, including a fixed seat 1 and a harrow 6, a towing mechanism 4 is arranged below the fixed seat 1, and an installation mechanism 2 with adjustable installation connection height is arranged at one end of the fixed seat 1 close to the towing mechanism 4, and the installation mechanism 2 includes a connecting seat 204 that can move up and down, and the connecting seat 204 that moves up and down can adjust the height of the connecting seat 204 when installing harrows 6 of different height models, thereby making the installation of harrows 6 of different heights and sizes more convenient, and a connecting mechanism that can quickly install agricultural machinery is arranged on one side of the connecting seat 204, and the connecting mechanism includes a liftable lifting rod 316, when it is necessary to install the towing harrow 6, the harrow 6 is moved to the groove set in the connecting seat 204, and the lifting rod 316 rises, so that the harrow 6 is installed on the connecting seat 204, thereby making the installation and connection of the harrow 6 more convenient.

[0025] The towing mechanism 4 includes a fixed block 401, and the fixed block 401 is rotatably installed at the connecting end of the tractor 5. The fixed block 401 is rotatably installed with a fixed rod 402 at the connecting end close to the tractor 5, and the fixed rod 402 passes through the fixed block 401, and the side end of the fixed block 401 away from the fixed rod 402 is rotatably installed with a connecting frame 403. The rotatably installed connecting frame 403 enables the towing mechanism 4 to make the towing machine 6 rotate along with the tractor 5 when the harrow 6 moves up, down, left and right, thereby making the towing movement of the harrow 6 more convenient. An elastic steel plate 404 is fixedly installed at the side end of the connecting frame 403 away from the fixed block 401, and a sleeve 405 is fixedly installed at one end of the elastic steel plate 404 away from the connecting frame 403. When the elastic steel plate 404 installed on the connecting frame 403 is installed and connected to the harrow 6, the sleeve 405 is pulled to bend the elastic steel plate 404, and then the sleeve 405 is sleeved on the harrow 6, thereby making it more convenient to install the towing mechanism 4 and connect the traction device.

[0026] A mounting seat 202 is fixedly installed on the side end of the fixing seat 1, and the mounting seat 202 is fixedly installed on the connecting end of the tractor 5. Moving grooves 207 are provided at both ends of the mounting seat 202. A mounting bolt 203 is slidably installed in the moving groove 207, and the connecting seat 204 is rotatably installed on the outer wall of the mounting bolt 203. The moving groove 207 provided on the mounting seat 202 enables the connecting seat 204 to move up and down, so that the connecting seat 204 can be used with a harrow 6 of different heights, thereby making it more convenient to install harrows 6 of different heights and sizes. A connecting block 201 is rotatably installed on the end of the connecting seat 204 away from the mounting bolt 203, and the connecting block 201 is fixedly installed on the upper end of the harrow 6. The connecting block 201 installed on the upper end of the harrow 6 is inserted into the groove provided on the connecting seat 204, and the lifting rod 316 rises, so that it is more convenient to install the connecting block 201 in the groove of the connecting seat 204.

[0027] The lower end of the connecting seat 204 is fixedly installed with an installation box 205, the upper end of the inner wall of the connecting seat 204 is fixedly installed with a limiting ring 206, and the limiting ring 206 is fixedly installed just above the lifting rod 316. The limiting ring 206 tries to prevent the lifting rod 316 from bending and causing damage when the lifting rod 316 drives the harrow 6. The bottom end of the inner wall of the installation box 205 is fixedly installed with an installation ring 307, the upper end of the installation ring 307 is fixedly installed with a lifting cylinder 308, and the lifting rod 316 is slidably installed on the inner wall of the lifting cylinder 308. The lower end of the lifting rod 316 is fixedly installed with a connecting rope 310, and the lower end of the connecting rope 310 is fixedly installed with a pulling handle 311. The installation box 205 is provided with a hole near the lower end of the pulling rope, and the pulling plate is provided at the lower end of the outer wall of the installation box 205. The pulling handle 311 makes it easier for the connecting rope 310 to drive the lifting rod 316 to rise and fall, thereby making it easier to disassemble and detach. The lifting rod 316 is fixedly installed with a telescopic spring 309 near the lower end of the connecting rope 310, and the mounting ring 307 is fixedly installed with a limit clamp 315 near the inner wall of the connecting rope 310, and the limit clamp 315 is set between two fixed plates, the fixed plates rotate with the openings facing downward, and a winding spring is set at the rotating connection of the fixed plates. When the connecting rope 310 rises, the limit clamp 315 squeezes the connecting rope 310 with the fixed plate set by the squeezing clamp under the pulling force of the connecting rope 310. The greater the pulling force, the greater the squeezing force, so that the connecting rope 310 is fixed and restricted in the mounting ring 307, so that when disassembling, only the pulling handle 311 needs to be pulled, which makes disassembly more convenient.

[0028] An air cylinder 301 is fixedly installed inside the connecting seat 204, and a piston ring 304 is slidably installed on the inner wall of the air cylinder 301. A piston rod 303 is fixedly installed on the end of the piston ring 304 close to the lifting rod 316, and a push plate 302 is fixedly installed on the end of the piston rod 303 away from the piston ring 304. When the connecting block 201 squeezes and pushes the push plate 302, the push plate 302 drives the piston rod 303 to move, so that the piston ring 304 begins to contract in the air cylinder 301, and the air pressure in the air cylinder 301 begins to increase.

[0029] The lower end of the gas cylinder 301 away from the push plate 302 is fixedly installed with an air transmission tube 305, and the end of the gas transmission tube 305 away from the gas cylinder 301 is fixedly installed with a pneumatic telescopic rod 306, and the output end of the pneumatic telescopic rod 306 is fixedly installed with a push rod 312. When the air pressure in the gas cylinder 301 begins to increase, the air pressure enters the pneumatic telescopic rod 306 through the air transmission tube 305301, so that the pneumatic telescopic rod 306 pushes the push rod 312 to move, and the end of the push rod 312 away from the pneumatic telescopic rod 306 is fixedly installed with a push block 313, and the push block 312 is fixedly installed with a push block 313. The moving rod 314 is rotatably mounted on one end of the limit clamp 315, and the moving rod 314 is rotatably mounted on the side end of the limit clamp 315 at one end away from the pushing block 313. When the pushing rod 312 pushes the pushing block 313 to move, the moving rod 314 moves, so that the limit clamp 315 opens and no longer squeezes and restricts the movement of the connecting rope 310. When the limit clamp 315 is not fixing the connecting rope 310, the telescopic spring 309 pushes the lifting rod 316 to rise, so that the connection between the connecting block 201 and the connecting seat 204 is more convenient.

[0030] Working principle: When the agricultural machinery traction device needs to be installed, the tractor 5 is driven to the position where the harrow 6 needs to be connected, the installation bolt 203 is loosened, the mobile connecting seat 204 is moved, the connecting seat 204 is moved to a suitable position, and the installation bolt 203 is tightened to fix the connecting seat 204, and the connecting block 201 fixedly installed on the harrow 6 is inserted into the connecting seat 204, so that the connecting block 201 pushes the push plate 302 to move, so that the piston rod 303 pushes the piston ring 304 to move, so that the air cylinder 3 The air pressure in 01 begins to increase, and the air pressure in the air cylinder 301 is transported to the pneumatic telescopic rod 306 through the air transmission tube 305, so that the pneumatic telescopic rod 306 drives the push rod 312 to move, and the push rod 312 drives the push block 313 to move, so that the limit clamp 315 opens, and the telescopic spring 309 pushes the lifting rod 316 to rise, and the lifting rod 316 passes through the connecting block 201, so that the lifting rod 316 is inserted into the limiting ring 206, thereby fixing the harrow 6 to one end of the traction device of the tractor 5.

[0031] When the tiller 6 needs to be separated from the traction device, the pulling handle 311 is pulled to make the connecting rope 310 drive the lifting rod 316 to descend, thereby separating the connecting block 201 from the connecting seat 204. When the pulling handle 311 is released and the connecting rope 310 rises, the limiting clamp 315 squeezes the connecting rope 310 with the fixing plate set by the squeezing clamp under the pulling force of the connecting rope 310, so that the connecting rope 310 is fixed and restricted in the mounting ring 307, thereby making the installation and detachment of the traction device more convenient.
