[0021] Embodiment 1

[0022] like Figure 1-Figure 4 As shown, a sowing device proposed by the utility model comprises a U-shaped support frame 1 and a handle 2, the handle 2 is connected to the middle position of the U-shaped support frame 1, a sowing drum 3 is arranged inside the U-shaped support frame 1, and fixing mechanisms for driving the sowing drum 3 to rotate are arranged at both ends of the sowing drum 3, and a sowing mechanism is arranged inside the sowing drum 3;

[0023] The sowing mechanism includes a storage assembly for storing and sowing seeds and a card and assembly for interconnecting with the sowing drum 3. The storage cylinder 4 in the storage assembly can store a certain amount of seeds. The discharge hole 6 opened on the storage cylinder 4 enables it to discharge the seeds into the sowing drum 3 during rotation, and the seeds are evenly discharged into the ground through the through holes on the sowing drum 3. The card and assembly facilitate the connection between the storage cylinder 4 and the sowing drum 3, so that the storage cylinder 4 can be easily removed for seed filling.

[0024] The storage assembly includes a storage cylinder 4, a cylinder cover 5 and an extrusion assembly for accelerating the discharge of seeds from the storage cylinder 4. A rectangular storage cavity is provided in the storage cylinder 4, and the storage cavity is used to set the extrusion assembly. The outer peripheral wall of the storage cylinder 4 is provided with discharge holes 6 that are circumferentially distributed and penetrate the storage cavity. The cylinder cover 5 is slidably connected to the storage cylinder 4, and a conical auxiliary groove 7 is provided at the discharge hole 6. After the seeds enter the storage cavity, they are separated into two parts by the extrusion plate 10 in the extrusion assembly. The extrusion plate 10 is moved to transport them to the discharge hole 6 and discharge them into the sowing drum 3. As the rotating plate 18 rotates, the sowing drum 3 rotates to scatter the tomato seeds into the soil.

[0025] The extrusion assembly includes a guide rod 8, a moving block 9, an extrusion plate 10 and a spring 11. The inner bottom surface of the storage tube 4 is provided with a sliding groove 12 for connecting the guide rod 8. The symmetrically arranged moving blocks 9 are slidably connected to the outer peripheral surface of the guide rod 8. The spring 11 is sleeved on the outer peripheral surface of the guide rod 8 and connected to the two moving blocks 9. The moving block 9 is connected to one end of the extrusion plate 10. The other end of the extrusion plate 10 is fixed with a protrusion 14, and the protrusion 14 is slidably connected to the guide groove 13 provided in the tube cover 5. The extrusion plate 10 is in the middle position to divide the storage tube 4 into two rectangular spaces. After the storage tube 4 rotates to allow the tomato seeds to enter the discharge hole 6 for discharge, the volume of the rectangular space decreases. The extrusion plate 10 moves in the opposite direction under the action of the spring 11 and accelerates the flow speed of the seeds. At this time, the protrusion 14 at the other end of the extrusion plate 10 slides in the guide groove 13 to guide the movement of the extrusion plate 10.

[0026] The symmetrically arranged extrusion plates 10 are provided with arc grooves 15 on one side away from each other. The arc grooves 15 are provided so that when the extrusion plates 10 are extruding seeds, the seeds will gradually move to the apex of the arc grooves 15 and enter the auxiliary grooves 7 and be discharged through the discharge holes 6.

[0027] The card and assembly includes a card and block 16, which are connected to the bottom surface of the storage tube 4 and the tube cover 5. The card and block 16 are slidably connected in the matching groove 17 provided on the fixing mechanism, and the card and block 16 and the matching groove 17 are both rectangular in shape. After the card and block 16 is inserted into the matching groove 17 on the rotating plate 18, the moving speed of the storage tube 4 is the same as that of the rotating plate 18 and the sowing drum 3. At the same time, because the card and block 16 and the matching groove 17 are slidably connected to each other, it is convenient to disassemble and replenish the seeds in the storage tube 4.

[0028] This embodiment can make the tomato seeds be discharged more evenly. When the tomato seeds enter the sowing drum 3 from the discharge hole 6, the number of seeds in the accommodating space in the storage tube 4 decreases, and the squeezing plate 10 moves linearly to keep squeezing the tomato seeds and make the seeds enter the discharge hole 6. The tomato seeds will not accumulate at both ends or in the middle of the storage tube 4, so that they are discharged more evenly.

The supporting teeth 19 contact the ground to drive the rotating plate 18 to rotate and then drive the sowing drum 3 to rotate for sowing, when the fixing bolt 20 is turned, the rotating plate 18 is driven to move along the axis of the fixing bolt 20 through the bearing, and the rotating plate 18 is close to or away from the sowing drum 3, and the sowing drum 3 can be disassembled after losing the restriction, which is convenient for replenishing seeds to the storage cylinder 4 and adjusting the extrusion component.

When the arc plate 21 rotates and sleeves outside the sowing drum 3, the arc plate 21 forms a sealing sleeve that seals the sowing drum 3. When the sowing drum 3 is moved to a suitable sowing location, the sowing drum 3 is closed to facilitate transportation, and the magnetic attraction between the magnetic block 22 and the arc plate 21 makes it easy to disassemble.
