A plurality of discharge holes 6 are opened at equal fillets below the ring side wall of the storage cylinder 1. A conical guide block 17 is fixed by bolts on the inner bottom wall of the storage cylinder 1. The conical guide block 17 can provide a discharge guide for the seeds in the storage cylinder 1. A vibration mechanism 7 matching the storage cylinder 1 is provided in the movable cylinder 4;

[0028] Connecting rods 8, there are two connecting rods 8, which are respectively fixed on the left and right sides of the upper end of the movable cylinder 4. A drive frame 9 is movably sleeved on the storage cylinder 1. The upper end of the connecting rod 8 is connected to the drive frame 9. A No. 1 spring 10 is fixedly arranged on the upper part of the drive frame 9. The upper end of the No. 1 spring 10 is fixedly connected to the handle 3;

[0029] The mounting cylinder 11 is movably mounted on the movable cylinder 4. Foot pedals 12 are fixedly mounted on the left and right side walls of the mounting cylinder 11 by bolts. Threaded rods 13 are screwed through the front and rear sides of the side walls of the mounting cylinder 11 by screwing. Several threaded holes 14 matching the threaded rods 13 are opened on the front and rear sides of the side walls of the movable cylinder 4.

[0030] The vibration mechanism 7 comprises:

[0031] Driving blocks 7-1, there are two driving blocks 7-1, which are respectively fixed by bolts in the strip grooves opened on the front and rear inner walls of the movable cylinder 4, and the front and rear sides of the outer wall of the storage cylinder 1 are fixed by bolts with connecting frames 7-2, and the connecting frames 7-2 are screwed with connecting cylinders 7-3 through a rotating shaft and a torsion spring;

[0032] The contact plate 7-4 is two and is fixed on the two connecting cylinders 7-3 by bolts respectively. The contact plate 7-4 is bonded and fixed with a protective pad 16, and the protective pad 16 is movably contacted with the outer wall of the storage cylinder 1. The protective effect of the protective pad 16 can prevent the contact plate 7-4 from directly hitting the storage cylinder 1 and causing damage. The connecting cylinder 7-3 is movably provided with a driving plate 7-5, and the driving plate 7-5 is provided with a rotating cylinder 15 through a shaft and a bearing. The rotating cylinder 15 is matched with the driving block 7-1 and is movably contacted. The rotation of the rotating cylinder 15 can effectively reduce the wear on the driving block 7-1. Two sliders 7-6 are fixedly provided on the driving plate 7-5, and the sliders 7-6 are slidably provided in the slide grooves provided on the connecting cylinder 7-3.

[0033] There are four arc-shaped guide rods 7-7, which are respectively fixed in four slide grooves by bolts, and the arc-shaped guide rods 7-7 are movably inserted into the slider 7-6. A No. 2 spring 7-8 is movably sleeved on the arc-shaped guide rod 7-7, and the two ends of the No. 2 spring 7-8 are respectively connected to the slider 7-6 and the inner wall of the slide groove.

[0034] When using the utility model, the seeds are stored in the storage barrel 1, and the handle 3 is held by hand, and the cone head 2 is pressed against the ground, and the foot is stepped on the foot pedal 12 until the foot pedal 12 contacts the ground. At this time, the cone head 2 and the movable barrel 4 are inserted into the ground to form a sowing hole, and then the driving frame 9 is pulled upward and the No. 1 spring 10 is compressed. The driving frame 9 drives the movable barrel 4 to move upward through the connecting rod 8, so that the movable barrel 4 is separated from the cone head 2. At the same time, the discharging hole 6 loses the shielding of the movable barrel 4, so that the seeds in the storage barrel 1 can fall into the sowing hole through the discharging hole 6, and in the process of the movable barrel 4 moving upward, the driving block 7-1 will be driven to move upward, so that the driving plate 7-5 drives the connecting barrel 7-3 to rotate through the slider 7-6, so that the torsion spring is twisted, and the connecting barrel 7-3 drives the contact plate 7-4 to flip and separate from the storage barrel 1. After the driving block 7-1 is separated from the conflict with the driving plate 7-5, the torsion spring resets and drives the connecting barrel 7-3 rotates in the opposite direction, so that the resistance plate 7-4 hits the storage barrel 1, causing the storage barrel 1 to vibrate, thereby preventing the seeds from being blocked in the storage barrel 1 or the discharge hole 6. After sowing, the handle 3 can be used to pull the movable barrel 4 and the cone head 2 out of the sowing hole, and the drive frame 9 can be released at the same time to make the No. 1 spring 10 reset and extend, and the drive frame 9, the connecting rod 8 and the movable barrel 4 can be pushed downward, so that the movable barrel 4 can close the discharge hole 6 again, and the upper part of the cone head 2 can be inserted into the storage barrel 1. It is set to the lower end of the movable cylinder 4, and in this process the driving block 7-1 will move downward, so that the driving block 7-1 will conflict with the driving plate 7-5, and the driving plate 7-5 will rotate downward with the rotating shaft as the center as the sliding of the slider 7-6, and at the same time the No. 2 spring 7-8 is compressed, and when the driving block 7-1 moves to the lowest position and disengages from the driving plate 7-5, the No. 2 spring 7-8 resets and pushes the slider 7-6 to slide in the slide groove, so that the driving plate 7-5 rotates to the initial position;

[0035] When it is necessary to adjust the sowing depth of seeds, the threaded rod 13 can be loosened to disengage the end of the threaded rod 13 from the threaded hole 14, and then the mounting tube 11 can be moved up and down to adjust the distance between the foot pedal 12 and the cone head 2, and then the threaded rod 13 can be tightened to insert the end of the threaded rod 13 into the threaded hole 14 at the corresponding position. In the subsequent sowing process, as the distance between the foot pedal 12 and the cone head 2 is adjusted, the foot pedal 12 can be in contact with the ground, thereby realizing the adjustment of the soil depth where the cone head 2 and the movable tube 4 are inserted, thereby realizing the adjustment of the seed sowing depth.

[0036] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0037] 1. Through the cooperation of the movable cylinder 4, the guide bar 5, the connecting rod 8, the driving frame 9, the No. 1 spring 10, the mounting cylinder 11, the foot pedal 12 and the threaded rod 13, the seed sowing depth can be adjusted according to the sowing requirements, thereby expanding the scope of application;

[0038] 2. Through the cooperation of the vibration mechanism 7, the storage barrel 1 can be vibrated during the sowing process to reduce the phenomenon of seeds being blocked inside it or the discharge hole 6.

[0039] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
