[0001] The present invention relates to the technical field of tractor brakes, in particular to a tractor brake convenient for repair and maintenance and a method thereof. Background Art

[0002] In agricultural production and engineering operations, tractors, as an important power machine, play an irreplaceable role. The brake is one of the key components for the safe operation of the tractor. Its performance is directly related to the operational safety and work efficiency of the tractor. In order to increase the service life of the tractor brake, it needs to be maintained.

The invention is implemented as follows: a walking tractor iron brake, a brake seat is mounted on the drive shaft and the bearing cover, and an iron sheet is mounted on the drive shaft near the wheel clamp. It includes an iron brake sheet, an iron clamp, a latch, a rivet, a deflection shaft, an adjustment rod, a reverse iron clamp, a soft pull wire, and a brake handle. In summary, the front brake of the walking tractor of the present invention is a safer driving device during agricultural production.

[0005] When the tractor is braked, the braking principle is that the hydraulic pump drives the brake caliper to clamp the brake disc to achieve braking.

However, when the disc brake is used for a long time, it is easy to cause damage to the brake disc and the entire brake disc needs to be replaced. Moreover, in rainy weather, when mud and rain splash onto the surface of the brake disc, when the brake disc is braked by the brake caliper, the sliding nature of the mud and sand will increase the braking distance, accelerate the wear of the brake disc, and be inconvenient for maintenance.

[0021] 1. In the tractor brake which is convenient for maintenance, the outer brake disc and the inner brake disc are fixed by fixing screws. When the outer brake disc is damaged, it only needs to be replaced, which is convenient for replacement and maintenance of the brake disc.

[0022] 2. In the tractor brake which is easy to repair and maintain, when the rainwater on the surface of the outer brake disc is absorbed and saturated by the sponge column, the pressure plate provided on the sliding inner wall of the column tube is subjected to the force of the tension spring and always keeps in contact with the surface of the rotating roller.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] One of the objects of the present invention is to provide a tractor brake that is easy to repair and maintain. Figure 1-Figure 8 As shown, it includes an outer brake disc 100 and an inner brake disc 102, the outer brake disc 100 and the inner brake disc 102 are fixed by fixing bolts, a reinforcing rib 101 is arranged between the outer brake disc 100, a brake caliper 103 is arranged on one side of the outer brake disc 100, the brake caliper 103 is used to brake the outer brake disc 100, an extension arm 200 is arranged below the brake caliper 103, a cylinder 201 is arranged at the end of the extension arm 200, a piston rod at the end of the cylinder 201 is provided with a moving plate 202, scraping rollers 203 and rotating rollers 205 are rotatably arranged on both sides of the moving plate 202, a groove 204 is arranged on the surface of the scraping roller 203, and when the scraping roller 203 is attached to the surface of the outer brake disc 100, the scraping roller 20 The outer brake disc 100 is rotated by friction force to scrape and clean the mud and sand attached to the surface of the outer brake disc 100. A cleaning component 300 is provided on the inner wall of the moving plate 202 near the scraping roller 203. The cleaning component 300 is used to automatically clean the mud and sand stuck in the groove 204. An arc groove is provided on the surface of the rotating roller 205. A sponge column 206 is provided in the arc groove. The sponge column 206 is used to automatically absorb the water on the surface of the outer brake disc 100. A water squeezing component 400 is provided on the inner wall of the moving plate 202 near the rotating roller 205. A cleaning component 500 is provided below the water squeezing component 400. The water squeezing component 400 is used to squeeze out the water absorbed in the sponge column 206 and collect it through the cleaning component 500.

[0040] Considering that in rainy weather, water and mud will splash on the surface of the brake disc when the vehicle is driving. During the braking process, the mud and water reduce the friction between the brake caliper 103 and the surface of the outer brake disc 100, resulting in an increase in the braking distance. In addition, due to the presence of mud, the outer brake disc 100 wears faster, increasing the replacement and maintenance requirements. Therefore, the inner diameter of the rotating roller 205 is smaller than the scraping roller 203, and the tops of the scraping roller 203 and the rotating roller 205 are both provided with transmission wheels, and a friction belt 207 is provided between the transmission wheels. When the scraping roller 203 is in contact with the surface of the outer brake disc 100 and rotates, it drives the rotating roller 205 to rotate. A baffle 208 is provided inside the movable plate 202. The baffle 208 is used to separate the scraping roller 203 and the rotating roller 205. A sensor 209 is provided on the top of the movable plate 202. The sensor 209 controls the movement of the piston rod at the end of the cylinder 201. During driving in rainy weather, the movable plate 202 is controlled to move in the axial direction by the piston rod at the end of the cylinder 201. The scraping roller 203 and the rotating roller 205 are obtained by the sensor 209. The distance information of the surface of the outer brake disc 100 is obtained. When the scraping roller 203 is in contact with the surface of the outer brake disc 100, the movable plate 202 stops axial movement. When the outer brake disc 100 rotates, the scraping roller 203 is driven to rotate by friction. During the rotation process, the scraping roller 203 scrapes the mud and sand splashed on the surface of the outer brake disc 100. Since the surface of the scraping roller 203 is provided with a groove 204, the splashed mud and sand are scraped and cleaned through the groove 204, so as to avoid the residual mud and sand on the surface of the outer brake disc 100, which may cause the brake caliper to be stuck. At the same time, when the groove 204 rotates, the friction belt 207 is driven by the transmission wheel to drive the rotating roller 205 to drive the sponge column 206 to rotate on the surface of the outer brake disc 100, and the rainwater on the surface of the outer brake disc 100 is adsorbed by the sponge column 206, thereby increasing the friction between the brake caliper 103 and the outer brake disc 100 during braking, improving the braking effect, thereby realizing automatic maintenance of the outer brake disc 100 and increasing the service life of the outer brake disc 100.

[0041] Taking into account that when the scraper roller 203 scrapes and removes the mud and sand adhered to the surface of the outer brake disc 100 during rotation, in rainy weather, the mud and sand are adhesive, resulting in the filling of the groove 204, affecting the scraper roller 203 The cleaning effect of the sand, therefore, the cleaning component 300 includes a support rod 301 arranged on the inner wall of the movable plate 202, and a crack cleaning block 302 is rotatably arranged on the surface of the support rod 301. The end of the crack cleaning block 302 is acute-angled. When the crack cleaning block 302 is horizontal, it fits against the inner wall of the groove 204. A plurality of liquid outlets 304 are provided on the surface of the crack cleaning block 302, and a torsion spring 303 is provided on the surface of the support rod 301. The two ends of the torsion spring 303 are respectively connected to the crack cleaning block 302 and the top of the movable plate 202. In a natural state, the crack cleaning block 302 is horizontally subjected to the force of the torsion spring 303. When the gap cleaning block 302 is in contact with the outer wall of the outer brake disc 100 and rotates under the friction force, the end of the gap cleaning block 302 is inserted into the inner wall of the groove 204. During the rotation of the scraper roller 203, the gap cleaning block 302 rotates along the scraper roller 203 and the surface of the groove 204 in turn. When the gap cleaning block 302 rotates on the surface of the scraper roller 203, the movable plate 202 is subjected to resistance and rotates on the surface of the support rod 301. The torsion spring 303 provided on the surface of the support rod 301 is deformed by the torsion force. When the gap cleaning block 302 scrapes back and forth when passing through the inner wall of the groove 204, the resistance encountered by the gap cleaning block 302 disappears. Under the action of the restoring force of the torsion spring 303, the gap cleaning block 302 is driven to rotate to a horizontal position. During the rotation, the mud and sand filled in the groove 204 are cleaned, thereby improving the mud and sand cleaning effect of the scraper roller 203.

[0042] In rainy weather, when the vehicle is driving, rainwater on the road surface is easy to splash onto the surface of the outer brake disc 100. When emergency braking is required, the lubricating effect of rainwater increases the braking distance. Therefore, the driver will increase the braking effect of the brake caliper 103, that is, step on the brake hard to accelerate the wear of the brake caliper 103 on the outer brake disc 100, thereby reducing the service life of the brake. The water squeezing component 400 includes a column 401 arranged on the inner wall of the movable plate 202. The column 401 is arranged in a row in the vertical direction. A pressure plate 403 is slidably provided at the end of the column 401. The ends of the column 401 and the pressure plate 403 are both provided with a tension spring 402. When the rotating roller 205 drives the sponge column 206 to rotate, the pressure plate 403 is used to press the sponge column 206 to make the water adsorbed inside the sponge column 206 fall. When there is a lot of rain, the sponge column 206 absorbs the water on the surface of the outer brake disc 100 saturatedly. Due to the pressure plate 403 provided on the inner wall of the column 401, the pressure plate 403 is When the sponge column 206 on the surface of the rotating roller 205 rotates to the end of the pressure plate 403, the pressure plate 403 moves under the force of the tension spring 402, so that the pressure plate 403 presses the surface of the sponge column 206, so that the water adsorbed inside the sponge column 206 falls in the vertical direction under the extrusion force. During driving, the surface of the rotating sponge column 206 is reciprocatedly squeezed by the pressure plate 403, so that the sponge column 206 always keeps a water-depleted state, which can improve the absorption efficiency of rainwater on the surface of the outer brake disc 100. At the same time, since the sponge column 206 has a cleaning effect, it can perform secondary cleaning on the mud and sand that is not scraped off by the scraper roller 203, so that the surface of the outer brake disc 100 that has passed the rotating roller 205 is always in a dry and clean state, thereby increasing the braking effect of the brake caliper 103 on the outer brake disc 100, thereby facilitating the maintenance of the brake device and increasing the service life of the brake device.

[0043] Since the cleaning block 302 is used to clean the silt on the inner wall of the groove 204, the silt is easily adhered to the surface, and the surface of the cleaning block 302 needs to be cleaned frequently. Therefore, a through hole is provided at the bottom of the movable plate 202, and a flaring plate 404 is provided at the through hole. The flaring plate 404 is used to collect the water falling from the sponge column 206. The cleaning component 500 includes a water collection cylinder 501 provided at the bottom of the movable plate 202, and a filter plate 503 is provided in the water collection cylinder 501. The water collection cylinder 501 is used to collect the water falling from the flaring plate 404. A micro water pump 502 is provided at the bottom of the movable plate 202 away from the water collection cylinder 501. The water suction end and the water discharge end of the micro water pump 502 are respectively connected to the water collection cylinder 501 and the cleaning block 302 through connecting pipes. Block 302, during driving, the rainwater absorbed inside the sponge column 206 is continuously squeezed by the pressure plate 403, so that the rainwater falls into the water collection tube 501 through the expansion plate 404. Since the water collection tube 501 is provided with a filter plate 503, the mud and sand can be filtered. Therefore, when it is necessary to clean the surface of the seam cleaning block 302, the micro water pump 502 is controlled to suck the rainwater inside the water collection tube 501, and the rainwater is input into the seam cleaning block 302 through the water outlet end of the micro water pump 502. The rainwater flows out through the liquid outlet 304 provided on the surface of the seam cleaning block 302, and the mud and sand attached to the surface of the liquid outlet 304 are cleaned, so as to prevent the mud and sand from attaching to the surface of the outer brake disc 100 for the second time, and facilitate the maintenance of the outer brake disc 100.

[0044] During specific use, when it is rainy outside, the piston rod at the end of the cylinder 201 controls the movable plate 202 to move in the axial direction, and the distance information between the scraper roller 203 and the surface of the outer brake disc 100 is obtained through the sensor 209. When the scraper roller 203 is in contact with the surface of the outer brake disc 100, the movable plate 202 stops axial movement, and the outer brake disc 100 drives the scraper roller 203 to rotate through the friction force when rotating. During the rotation process, the scraper roller 203 scrapes the mud and sand splashed on the surface of the outer brake disc 100. Since the surface of the scraper roller 203 is provided with a groove 204, the splashed mud and sand are scraped and cleaned through the groove 204, so as to avoid the residual mud and sand on the surface of the outer brake disc 100, which causes the braking effect of the brake caliper 103 to be weakened. At the same time, in the groove 2 When 04 rotates, the friction belt 207 is driven by the transmission wheel to transmit, so that the rotating roller 205 drives the sponge column 206 to rotate on the surface of the outer brake disc 100, and the rainwater on the surface of the outer brake disc 100 is absorbed by the sponge column 206, thereby increasing the friction between the brake caliper 103 and the outer brake disc 100 during braking, thereby improving the braking effect. Since the outer brake disc 100 and the inner brake disc 102 are fixed by fixing screws, when the outer brake disc 100 is damaged, it only needs to be replaced, which is convenient for replacement and maintenance of the brake disc. At the same time, by setting reinforcing ribs 101 between the outer brake discs 100, the heat dissipation area of ​​the outer brake disc 100 is increased while ensuring the strength of the outer brake disc 100, thereby improving the braking effect.

[0045] The braking principle of the brake is that the hydraulic pump drives the brake caliper 103 to clamp the outer brake disc 100 to achieve braking. When the outer brake disc 100 is clamped, the friction force will prevent the rotation of the wheel, and the disc brake can quickly apply the braking force, thereby shortening the braking distance. During the rotation of the scraper roller 203, the gap cleaning block 302 rotates along the scraper roller 203 and the surface of the groove 204 in turn. When the gap cleaning block 302 rotates on the surface of the scraper roller 203, the movable plate 202 is subjected to resistance and rotates on the surface of the support rod 301. The torsion spring 303 provided on the surface of the support rod 301 is subjected to torsion and deformed. When the gap cleaning block 302 scrapes back and forth when passing through the inner wall of the groove 204, the resistance encountered by the gap cleaning block 302 disappears. Under the action of the restoring force of the torsion spring 303, the gap cleaning block 302 is driven to rotate to a horizontal position. During the rotation, the mud and sand filled in the groove 204 are cleaned, thereby improving the mud and sand cleaning effect of the scraper roller 203.

[0046] When there is a lot of rain, when the sponge column 206 absorbs saturated water on the surface of the outer brake disc 100, the pressure plate 403 provided on the inner wall of the column tube 401 is subjected to the force of the tension spring 402, and always keeps in contact with the surface of the rotating roller 205. When the sponge column 206 on the surface of the rotating roller 205 rotates to the end of the pressure plate 403, the pressure plate 403 is moved by the force of the tension spring 402, so that the pressure plate 403 presses the surface of the sponge column 206, so that the water adsorbed inside the sponge column 206 is squeezed and falls in the vertical direction. The overpressure plate 403 reciprocates and squeezes the surface of the rotating sponge column 206, so that the sponge column 206 always maintains a water-depleted state, which can improve the adsorption efficiency of rainwater on the surface of the external brake disc 100. At the same time, since the sponge column 206 has a cleaning effect, it can perform secondary cleaning on the mud and sand that has not been scraped off by the scraper roller 203, so that the surface of the external brake disc 100 that has passed through the rotating roller 205 is always in a dry and clean state, increasing the braking effect of the brake caliper 103 on the external brake disc 100, thereby facilitating the maintenance of the brake device and increasing the service life of the brake device.

[0047] The second object of the present invention is to provide a maintenance method for a tractor brake, including any one of the above tractor brakes that is convenient for maintenance, comprising the following steps:

[0048] S1. The cylinder 201 at the end of the extension arm 200 drives the movable plate 202 to move in the axial direction, and the distance information between the scraper roller 203 and the surface of the outer brake disc 100 is obtained through the sensor 209. When the scraper roller 203 is in contact with the surface of the outer brake disc 100, the movable plate 202 stops axial movement. At this time, the scraper roller 203 is in contact with the surface of the outer brake disc 100. When the outer brake disc 100 rotates, the scraper roller 203 is driven to rotate by the friction force. Since the surface of the scraper roller 203 is provided with a groove 204, when the groove 204 rotates, the friction belt 207 is driven by the transmission wheel to transmit, so that the rotating roller 205 drives the sponge column 206 to rotate on the surface of the outer brake disc 100, and the rainwater on the surface of the outer brake disc 100 is adsorbed by the sponge column 206.
