The furrowing mechanism is arranged corresponding to the multiple sowing rotary barrels 3, so that the seeds dropped from the seeding trough 17 of the sowing rotary barrel 3 can fall into the opened furrows.

[0031] When in use, seeds are added to the sowing rotary barrel 3 through the feeding port 4, and then the lid is tightly closed and the driving mechanism is turned on to make the barrel shaft 2 drive the sowing rotary barrel 3 to rotate, and then the frame 1 is driven forward to make the furrowing mechanism furrow, so that the seeds dropped from the lower seed groove 17 of the sowing rotary barrel 3 can fall into the opened furrow.

[0032] Compared with the prior art, the visualized rapeseed precision sowing device provided in the present embodiment can realize the precision and visualized sowing of rapeseed seeds through the cooperation of the frame 1, the barrel shaft 2, a plurality of sowing rotary barrels 3, the driving mechanism, the walking mechanism and the furrowing mechanism; the sowing rotary barrel 3 keeps the seeds therein in a loose state at all times during the rotation process, which can reduce the possibility of clogging the through hole of the seeding groove 17, and the seeding groove 17 is constantly repeated in the upward and downward processes, which can also reduce the possibility of clogging the through hole of the seeding groove 17, so that the sowing can be more accurate, and the sowing rotary barrel 3 is at least partially transparent, so that the operator can see the situation therein from the outside, so that the dredging maintenance and adjustment of the sowing plan can be carried out in time, which is conducive to uniform sowing.

[0033] Please also read Figures 1 to 5 The present invention provides a specific implementation method based on the first implementation method as follows:

[0034] In order to prevent the seeds in the seeding rotary barrel 3 from being squeezed by too many or too few seeds, thereby changing the amount of seeds falling from the through holes of the seeding rotary barrel 17 and causing uneven seeding, a baffle 19 is provided on the inner side of the seeding rotary barrel 17. The two sides of the baffle 19 are tightly matched with the two bottom surfaces of the seeding rotary barrel 3, and one end is connected to the side wall of the seeding rotary barrel 3, and the other end forms an opening with the side wall of the seeding rotary barrel 3. The baffle 19, the seeding rotary barrel 3 and the seeding rotary barrel 17 form a cavity with an opening.

[0035] During the rotation of the sowing rotary barrel 3, when one of the seeding grooves 17 rotates to the lower part of the sowing rotary barrel 3, some seeds will enter the cavity from the opening, but the cavity will not be filled. Therefore, the seeds entering the cavity can remain fluffy and are not affected by the amount of seeds inside the sowing rotary barrel 3. This can ensure that the amount of sowing each time is fixed and achieve precise quantitative control.

[0036] The baffle 19 is a cantilever elastic plate and its two sides are movably matched with the two bottom surfaces of the sowing rotary barrel 3. A counterweight 20 is provided at the free end of the baffle 19. The counterweight 20 drives the cantilever elastic plate to move under the action of gravity, so that when the lower seeding groove 17 rotates to the lower part of the sowing rotary barrel 3, the opening becomes smaller to prevent too many seeds from entering the cavity, and when the lower seeding groove 17 rotates to the upper part of the sowing rotary barrel 3, the opening becomes larger, so that the seeds in the cavity can be discharged smoothly, and it is prevented that there are too many seeds in the cavity when it rotates to the lower part of the sowing rotary barrel 3 next time.

[0037] The counterweight block 20 is detachably connected to the baffle plate 19 , and a plurality of mounting positions for mounting the counterweight block 20 are provided at different positions on the baffle plate 19 , so that the size of the final opening can be adjusted by adjusting the weight of the counterweight block 20 and the position on the baffle plate 19 .

[0038] The counterweight 20 can also be a magnet, which can absorb ferromagnetic substances in seeds to prevent the seed surface from being scratched, and can also adjust the size of the opening by applying force to the counterweight 20 through another magnet fixedly arranged on the outside of the sowing drum 3.

[0039] A transmission is provided between the barrel shaft 2 and the driving mechanism to adjust the rotation speed of the barrel shaft 2 .

[0040] The diameter of the through hole is 1-2 mm so that the seeds can fall smoothly.

The mounting base 5 is fixedly mounted on the top of the frame 1, the reduction motor 6 is fixedly mounted on the top of the mounting base 5, the two first pulleys 7 are fixedly mounted on the output shaft of the reduction motor 6 and one end of the barrel shaft 2, and the same first belt is wound around the two first pulleys 7. The sowing rotary barrel 3 can be driven to rotate through the driving mechanism, so that the rapeseed in the sowing rotary barrel 3 falls out of the sowing rotary barrel 3 from the discharge hole during the tumbling process.

[0043] The traveling mechanism includes two wheel axles 8, two second pulleys 9 and two moving wheels 10. The wheel axle 8 is rotatably mounted on the bottom of the frame 1. The two moving wheels 10 are fixedly mounted on the two wheel axles 8 respectively. The two second pulleys 9 are fixedly mounted on one of the wheel axles 8 and one end of the barrel shaft 2 respectively. The same second belt is wound around the two second pulleys 9.

[0044] The furrowing mechanism includes a cross bar 11, multiple furrowing plowshares 12, two screws 13, two sprockets 14 and a turning handle 15. The cross bar 11 is arranged below the frame 1. The multiple furrowing plowshares 12 are fixedly installed on one side of the cross bar 11. Two mounting grooves are provided on the top of the cross bar 11. Bearings are fixedly installed in the two mounting grooves. Two screws 13 are rotatably installed in the two mounting grooves. The inner rings of the two bearings are fixedly sleeved on the two screws 13 respectively. The two screws 13 are threadedly connected to the frame 1. The two sprockets 14 are fixedly sleeved on the two screws 13 respectively. The same chain is wound around the two sprockets 14. The turning handle 15 is fixedly installed on the top of one of the screws 13. Through the furrowing mechanism, a planting furrow can be opened on the planting ground during the forward movement of the device.

[0045] Two push handles 16 are fixedly mounted on the frame 1, and the push handles 16 are used to hold the device forward and control the forward direction.

[0048] Next, the push handle 16 is held by hand to start the reduction motor 6, and the sowing rotary barrel 3 on the barrel shaft 2 is driven to rotate through the two first pulleys 7 and the first belt, and the moving wheel 10 is driven to rotate through the two second pulleys 9 and the second belt, so that the device moves forward, and multiple furrowing plowshares 12 open planting furrows in the process of moving forward. In the process of the sowing rotary barrel 3 rotating, the rapeseed rolls in the sowing rotary barrel 3, and the rapeseed passes through the discharge hole on the lower seeding groove 17 and falls into the planting furrow from the discharge hole, and the rotation speed of the sowing rotary barrel 3 is proportional to the speed of the device moving forward, so that the rapeseed is sown accurately, and then the sowing density of the rapeseed is uniform;

[0049] Furthermore, during the sowing process, the amount of rapeseed remaining in the sowing rotary barrel 3 can be clearly seen through the transparent sowing rotary barrel 3, so that rapeseed can be added in time.
