Description

Technical Field

[0001] The utility model relates to the technical field of agricultural harvesters, in particular to an agricultural harvester. Background Art

[0002] A harvester is an integrated machine for harvesting crops. It can complete harvesting and threshing at one time, and concentrate the grains in a storage bin, and then transport the grains to a transport vehicle via a conveyor belt. It can also be harvested manually by spreading the stalks of crops such as rice and wheat in the fields, and then using grain harvesters to pick up and thresh them, thus harvesting the grains and straw of cereal crops such as rice and wheat.

[0003] At present, agricultural harvesters in the prior art are usually arranged in cooperation with a bracket cross bar and a soil plow. During use, the harvested land can be tilled and loosened, thereby playing the role of tilling the land and achieving the purpose of increasing the function of the harvester. When replacing the harvesting head, since the existing agricultural harvesters generally install the harvesting head by bolts, but a large number of bolts are required, a lot of time is wasted when replacing the harvesting head, which reduces work efficiency and is inconvenient to disassemble and assemble the harvesting head. In addition, during actual use, accidents may occur, and foreign objects or living things may enter the harvesting head. The harvesting head may lack an emergency stop design. When the drive mechanism of the harvester is shut down, the harvesting head may still rotate due to inertia, which is not easy to stop urgently, and there is a problem of inconvenience in stopping the harvesting head urgently.

Through the arrangement of the harvesting head 3, the mounting block 5, the mounting bar 6, the transmission rod 7, the clamping block 11, the threaded rod 12, the pressing block 13, the limiting block 22, the sliding block 23, the fixing rod 24, and the spring 25, an agricultural harvester is provided with the convenience of disassembling and assembling the harvesting head 3, avoiding the inconvenience of disassembling and assembling the harvesting head 3.

[0032] When in use, the mounting strip 6 on the harvesting head 3 is inserted into the mounting block 5, and then the mounting block 5 is pressed downward and the transmission rod 7 is rotated. As the mounting block 5 moves downward, the mounting block 5 pushes the sliding block 23 downward through the fixing rod 24, the spring 25 contracts, and the limiting block 22 returns to the transmission rod 7 under the pull of the sliding block 23, so that the transmission rod 7 can rotate, and the transmission rod 7 drives the gear 2 27, and the gear 27 is engaged with the gear 1 26, so that the threaded rod 12 rotates, and the clamping block 11 moves and enters the mounting strip 6, thereby restricting the mounting strip 6, and then the pressing block 13 is released, and the spring 25 lifts the sliding block 23, so that the limiting block 22 enters the mounting block 5, restricts the transmission rod 7, and makes the harvesting head 3 more stable after installation. Example 2

[0033] See also Figures 1 to 9 The utility model provides a technical solution: an agricultural harvester, comprising a device body 1, a support frame 2 is installed on the top of the device body 1, a stopper circular plate 9 is movably connected to the inner wall of the support frame 2, a transmission shaft 8 is fixedly connected to the inner wall of the stopper circular plate 9, one end of the transmission shaft 8 is fixedly connected to a transmission wheel 4, and the other end of the transmission wheel 4 is fixedly connected to a mounting block 5;

[0034] The inner wall of the support frame 2 is fixedly connected with an electric telescopic rod 14, one end of the electric telescopic rod 14 is fixedly connected with a moving block 15, one end of the moving block 15 is fixedly connected with a first gear bar 16, one end of the first gear bar 16 is fixedly connected with a connecting rod 17 at the bottom, one end of the connecting rod 17 is fixedly connected with a brake pad 20, the bottom of the first gear bar 16 is meshed with a transmission gear 19, the bottom of the transmission gear 19 is meshed with a second gear bar 18, one end of the second gear bar 18 is fixedly connected with a connecting rod 17 at the bottom, and the number of connecting rods 17 is two The connecting rod 17 is distributed on the first gear bar 16 and the second gear bar 18.
