Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, and more specifically, to a fixing device for a rapeseed seed drill. Background Art

[0002] A seeder refers to a planting machine that sows crops and seeds. It has the characteristics of uniform sowing, consistent sowing depth, stable row spacing, good soil covering, seed saving and high work efficiency. A seeder used for a certain type or crop is often named after the crop type, such as grain drill, corn hole seeder, cotton seeder, forage spreader, etc.

[0003] During rapeseed sowing, operators often use corresponding rapeseed seeders to spread rapeseed seeds. Since the rapeseed seeder needs to be transported many times during the sowing process, and the existing transport device does not fix the rapeseed seeder during actual use, the probability of the seeder being damaged due to collisions during transportation will increase. This not only causes unnecessary economic losses to the operators, but also affects the subsequent rapeseed seed sowing efficiency. Therefore, it needs to be improved. Utility Model Content

[0027] A mounting frame 1, a fixing frame 2 is movably sleeved in the middle of the top of the mounting frame 1, the bottom of the fixing frame 2 passes through the mounting frame 1 and extends to the inside of the mounting frame 1, and limiting grooves 9 are provided on both sides of the top of the inner surface of the fixing frame 2;

[0028] Rollers 3, the number of which is four, and the bottoms of the four rollers 3 are movably connected to the top of the mounting frame 1;

[0029] A fixing mechanism, the fixing mechanism is arranged in the inner cavity of the fixing frame 2;

[0030] Among them, the fixing mechanism includes a pneumatic cylinder 4, which is fixedly connected to the bottom of the inner cavity of the fixed frame 2, and a moving plate 5 is fixedly connected to the top of the pneumatic cylinder 4. The two sides of the moving plate 5 are hinged with inclined plates 6, and the other end of the inclined plate 6 is hinged with a clamping plate 7. The top of the clamping plate 7 is fixedly connected with a rectangular block 8. The outer surface of the rectangular block 8 is movably connected to the inner surface of the limiting groove 9, and the outer surface of the clamping plate 7 is movably connected to the inner surface of the fixed frame 2. The up and down movement of the moving plate 5 will cause the clamping plate 7 to move left and right.

[0031] When the pneumatic cylinder 4 starts to run, the moving plate 5 will move vertically upward and the two inclined plates 6 will start to move. At this time, under the limiting action of the limiting groove 9, the two clamping plates 7 will drive the two rectangular blocks 8 to move horizontally opposite to each other. When the outer surface of the clamping plate 7 contacts the outer surface of the roller 3, the roller 3 will be fixed.

[0032] Among them, both sides of the middle part of the inner cavity of the mounting frame 1 are fixedly connected with fixing blocks 10, the left side of the fixing block 10 is fixedly connected with a driving motor 11, and the other end of the output shaft of the driving motor 11 is fixedly sleeved with a threaded rod 12.

[0033] When the driving motor 11 starts to run, the threaded rod 12 will rotate.

[0034] The right end of the threaded rod 12 penetrates through the fixed block 10 and extends to the inside of the fixed block 10 and is movably sleeved with the inside of the fixed block 10 . The outer surface of the threaded rod 12 is threadedly sleeved with a movable plate 13 .

[0035] When the threaded rod 12 rotates, the moving plate 13 will move horizontally to the right.

[0036] A rectangular groove 14 is provided in the middle of the bottom of the mounting frame 1 , and a limit block 15 is movably connected inside the rectangular groove 14 . The top of the limit block 15 is fixedly connected to the bottom of the moving plate 13 .

[0043] Such a design improves the fixing effect of the clamping plate 7 on the roller 3 .

[0044] The working principle and use process of this utility model:

[0045] First, when the rapeseed planter needs to be fixed, the pneumatic cylinder 4 is started, which will cause the moving plate 5 to move vertically upward and the inclined plate 6 to start moving. At this time, under the limiting action of the limiting groove 9, the two clamping plates 7 will drive the two rectangular blocks 8 to move horizontally opposite to each other, and finally complete the fixing of the roller 3, avoiding the situation where the planter is bumped during transportation and causing damage to the equipment.

[0046] When it is necessary to fix the larger roller 3 and the initial height of the device does not meet the requirement, the drive motor 11 is started, the threaded rod 12 is rotated, and the movable plate 13 drives the limit block 15 to move horizontally to the right under the limiting action of the rectangular groove 14, so that the connecting rod 16 starts to move, and then the fixing frame 2 moves vertically upward under the limiting action of the mounting frame 1, and finally the clamping plate 7 moves upward together, thereby realizing the function of adjusting the height according to the size of the roller 3 of different models of seed drills, and improving the fixing effect of the clamping plate 7 on the rollers 3 of different models.
