Technical Field

[0001] The utility model belongs to the technical field of seed drill equipment, in particular to a multi-film multi-row seed drill. Background Art

[0002] Due to the intensified efforts to adjust the agricultural industrial structure, crop planting in many areas has developed towards characteristic agricultural planting. The crops planted include peppers, tomatoes, cowpeas, potatoes, peanuts, watermelons, etc. The work of furrowing and ridge forming, film laying, and sowing of these fruit and vegetable crops is only completed manually, which is not only time-consuming and labor-intensive, but also has low operating efficiency. In addition, there are quality problems in the furrowing and ridge forming. In addition, heavy physical labor also limits the expansion of the planting area of ​​such crops. It not only cannot meet the needs of the current agricultural industrial structure adjustment, but also restricts the further development of characteristic agricultural planting, so sowing equipment has been produced.

[0003] When digging furrows, the existing seeder can only dig two or three furrows in a row at a time, resulting in the need to dig furrows many times on the same piece of farmland to complete the work, wasting a lot of time, resulting in greatly reduced sowing efficiency, inconvenience for users, and reducing the practicality of the seeder. Utility Model Content

[0006] The beneficial effects of the utility model are as follows:

[0007] 1. The utility model sets a fixed shaft, drives the screw to rotate through the first motor, and drives the adjusting seat to move up and down on its surface, thereby driving the connecting frame and the furrowing disc on the right side to move, so as to adjust the depth of the furrowing disc inserted into the ground, thereby obtaining the required furrow depth, and then controls the driving box to drive the push handle to rotate, so that the furrowing disc is forced to rotate to open a furrow on the cultivated land, and can open two rows of furrows at the same time, thereby saving a lot of time and greatly improving the sowing efficiency.

[0008] 2. The utility model sets a seeding roller. After the groove is opened in the front by the groove-opening disc, the second motor is started to drive the seeding roller to rotate. When the seed groove on the surface of the seeding roller rotates to the inside of the hopper, the seeds inside it will fall into the seed groove. When the seeding roller drives the seed groove downward, the seeds inside it will fall into the opened groove. At the same time, the rotation speed of the second motor can be adjusted to control the seeding spacing to adapt to the required intervals for the growth of different plants, which greatly improves the applicability of the seeder.

[0016] refer to Figure 1 , Figure 2 and Figure 4 A hopper 16 is fixedly connected to the top of the connecting frame 10, a motor frame 17 is fixedly connected to the front of the hopper 16, the bottom of the motor frame 17 is fixedly connected to the connecting frame 10, a second motor 18 is fixedly connected to the inside of the motor frame 17, a seeding roller 19 is fixedly connected to the output end of the second motor 18, the seeding roller 19 penetrates to the back of the connecting frame 10, and a plurality of seed grooves 20 are opened on the surface of the seeding roller 19, the number of the seed grooves 20 is the same as the ditching disc 15, and the seed grooves 20 correspond to the ditching disc 15 and are located on the same horizontal line.

[0017] In this embodiment, through the setting of the seeding roller 19, after the groove-forming disc 15 forms a groove in the front, the second motor 18 is started to drive the seeding roller 19 to rotate. When the seed groove 20 on the surface of the seeding roller 19 rotates to the inside of the hopper 16, the seeds inside it will fall into the seed groove 20. When the seeding roller 19 drives the seed groove 20 downward, the seeds inside it will fall into the opened groove. At the same time, the speed of the second motor 18 can be adjusted to control the seeding spacing to adapt to the required intervals for the growth of different plants, which greatly improves the applicability of the seeder.

[0018] refer to Figure 1 , Figure 2 and Figure 4 The top of the hopper 16 is fixedly connected to a top frame 21, the top of the top frame 21 is fixedly connected to an electric push rod 22, the output end of the electric push rod 22 passes through the bottom of the top frame 21 and is fixedly connected to a connecting rod 23, and a plurality of anti-blocking strips 24 are fixedly connected to both sides of the surface of the connecting rod 23.

[0019] By setting the anti-blocking strip 24, during sowing, the electric push rod 22 is started to drive the connecting rod 23 to extend and retract up and down, so that the connecting rod 23 drives the anti-blocking strip 24 to move up and down inside the hopper 16, which has a stirring effect on the seeds, thereby avoiding the problem of seeds being blocked and unable to fall into the seed slot 20, and further improving the practicality of the seeder.

[0020] refer to Figure 2 and Figure 4 The left wall of the hopper 16 is fixedly connected to the limiting groove 25, the surface of the top of the connecting rod 23 is fixedly connected to the fixing ring 26, the left side of the fixing ring 26 is fixedly connected to the limiting block 27, and the limiting block 27 is slidably connected to the fixing ring 26.

[0024] refer to Figure 2 and Figure 3 Both sides of the top of the bottom plate 5 are fixedly connected with sliding columns 30, the top end of the sliding column 30 passes through the adjustment seat 9 and is slidably connected thereto, and the top end of the sliding column 30 is fixedly connected to the bottom of the top plate 7.

[0025] In this embodiment, the adjustment seat 9 is limited by the setting of the sliding column 30 to prevent its deflection from causing the groove opened by the groove opening disc 15 to be distorted, and further support is provided for the adjustment seat 9, reducing the weight borne by the screw 6, thereby extending the service life of the screw 6.

[0026] The utility model puts seeds into the hopper 16, and starts the electric push rod 22 to drive the connecting rod 23 to extend and retract up and down, so that the connecting rod 23 drives the anti-blocking strip 24 to move up and down in the hopper 16, which has a stirring effect on the seeds and avoids seed blockage. Then the first motor 8 is started to drive the screw 6 to rotate, and the screw 6 drives the adjustment seat 9 to move up and down on its surface, thereby driving the connecting frame 10 and the ditching disc 15 on the right side thereof to move, so that the depth of the ditching disc 15 inserted into the ground can be adjusted, so as to obtain the required groove depth, and then the drive box is controlled 1 drives the push handle 2 to rotate, so that the furrowing disc 15 is forced to rotate to open two rows of furrows on the cultivated land, and the second motor 18 is started to drive the sowing roller 19 to rotate. When the seed groove 20 on the surface of the sowing roller 19 rotates to the inside of the hopper 16, the seeds inside it will fall into the seed groove 20. When the sowing roller 19 drives the seed groove 20 downward, the seeds inside it will fall into the opened furrow. After the seeds fall into the furrow, the scraper 28 located at the rear side of the seeds will immediately comb the turned-up soil into the interior of the furrow, cover the seeds and complete the sowing.
