[0003] For example, application No. 202323578044.6 discloses a vegetable planting and sowing device, which is installed with a quantitative seeding roller by magnetic fixation. The seeding disc on the quantitative seeding roller can quantitatively accommodate seeds. Then, the sowing handle drives the quantitative seeding roller to rotate back and forth 180 degrees in the seeding cylinder during the process of lifting and pressing the entire sowing device for sowing, so that the seeds in the seeding disc can be driven from the upper part to the lower part so that they fall into the drop tube and are sown from the lower end, and quantitative sowing can be completed each time.

[0004] However, the traditional vegetable sowing method mainly relies on manual operation, which has many problems and limits the scale and modernization of vegetable planting. Although some simple sowing tools are used, these tools have single functions and cannot achieve the integrated operation of sowing, fertilizing, turning over and covering the soil, resulting in a cumbersome sowing process and low efficiency. Therefore, a vegetable planting sowing device is proposed to solve the above problems. Summary of the Invention

[0092] The L-shaped baffle 51 is connected to the cavity of the inner cylinder 22 and is located above the circular hole. It is used to guide the fertilizer and seeds along the circular hole and the through hole to slide into the first inserting plate 272 and the second inserting plate 273.

[0093] A lower material cylinder 53 is connected to the cavity of each inner cylinder 22 via a rotating shaft 52, and the outer wall of the lower material cylinder 53 is in contact with the L-shaped baffle 51 and the inner wall of the cavity of the inner cylinder 22;

[0094] A groove is provided on one side of the outer wall of the discharge barrel 53 for accommodating vegetable seeds and fertilizers, and an arc-shaped groove is provided on one side of the cavity. A torsion spring is provided on the outer wall of the rotating shaft 52 for rotating the discharge barrel 53 at the arc-shaped groove for releasing vegetable seeds and fertilizers;

[0095] The reset rod 55 is hinged to the outer wall of the inner cylinder 22;

[0096] The spring piece 56 is connected to the outer wall of the inner cylinder 22 and is used to resist the upward deflection of the reset rod 55;

[0097] A plurality of wedge-shaped grooves 57 are formed on the outer wall of the outer drum 23 and abut against one side of the reset rod 55 to prevent the reset rod 55 from deflecting downward.

[0098] The round rod 54 is fixedly connected to the outer wall of the discharge barrel 53 and movably passes through the arc hole opened on the outer wall of the inner barrel 22 and contacts the outer wall of the reset rod 55 to push the round rod 54 to move.

[0099] A chute is provided in the cavity of the inner cylinder 22, and a rack 58 is slidably connected in the chute;

[0100] The outer wall of the discharge barrel 53 is provided with a tooth groove, which is engaged with the rack 58 to drive the rack 58 to move;

[0101] An opening is provided above the rack 58, and two movable rods 59 are connected to the opening of the rack 58. When the rack 58 moves, the fertilizer and vegetable seeds are moved and cleared.

[0102] Working principle: When sowing vegetables, after placing the sowing device in the plot where sowing is required, the push handle installed on the sowing frame 1 is directly pushed to push the sowing frame 1 to move, and the outer roller 23 and the roller 4 are moved. At this time, when the sowing frame 1 moves, the two flaps 33 will push the soil to both sides when they come into contact with the soil, thereby achieving the purpose of turning the soil, thereby achieving the effect of facilitating sowing, and the return spring 35 can push the two flaps 33 to open each other around their hinges, thereby achieving the purpose of keeping turning the soil;

[0103] Furthermore, according to the requirement of the intermediate spacing of sowing, by rotating the bidirectional screw 21, the bidirectional screw 21 will push the two inner cylinders 22 to move simultaneously, and adjust the distance between the two inner cylinders 22 according to the requirement of the inter-seed spacing, and then synchronously drive the guide tube 24 and the barrel 25 to move on the fixed rod 26 at the same time, so as to achieve the purpose of synchronous adjustment. At the same time, the U-shaped rod 39 can also drive the movable plate to move, and cooperate with the spring 38 to achieve synchronous adjustment of the two movable plates to adapt to the movement of the inner cylinder 22, so as to adjust the position of the flap 33 and achieve the purpose of turning the soil after the inter-seed spacing is adjusted;

[0104] Then, when the seeding rack 1 moves, the outer drum 23 is inserted into the soil through the insertion mechanism 27 and rotates around the inner drum 22, thereby driving the insertion mechanism 27 to rotate. At this time, when the second plug plate 273 is pushed by the torsion spring 275, it drives the second plug plate 273 to deflect in the opposite direction and fit into the first plug plate 272 by pushing the lever 274. When it rotates and contacts the soil and is inserted into the soil under the gravity of the equipment, the lever 274 will rotate and hit the roller on the fixed block 276. At this time, the lever 274 will be deflected, and the lever 274 will be pushed to deflect around its hinge and press the torsion spring 275. When the lever 274 is deflected, the second plug plate 273 is driven to deflect away from the first plug plate 272, so that the fertilizer and vegetable seeds between the first plug plate 272 and the second plug plate 273 can be released into the inserted soil. When the roller is out of contact with the lever 274, the lever 274 is pushed back to its original position by the torsion spring 275, and the second plug plate 273 and the first plug plate 272 are brought closer to each other. Then, during the movement, the roller 4 pushes the turned-up soil to flatten it, thereby achieving simultaneous sowing and fertilization, and covering the soil, thereby increasing the sowing speed.

[0105] The fertilizer and vegetable seeds in the barrel 25 are respectively introduced into the cavity of the inner barrel 22 through the guide tube 24. At this time, the fertilizer and vegetable seeds are respectively located inside the cavity and above the L-shaped baffle 51. When the outer drum 23 rotates, it drives the multiple wedge-shaped grooves 57 opened on its outer wall to rotate along with it. At this time, when the reset rod 55 is separated from the wedge-shaped groove 57 and hits the inner wall of the outer drum 23, it will hit the reset rod 55 and deflect, and compress the spring 56. At this time, the reset rod 55 is 5 no longer supports the round rod 54, so under the action of the coil spring in the rotating shaft 52, the rotating shaft 52 is twisted to rotate, and the discharge barrel 53 is synchronously driven to rotate, thereby changing the deflection of the groove on the rotating barrel 53, so that the vegetable seeds and fertilizers in the groove are synchronously driven and enter the arc groove to slide down, and enter the circular hole through the lower half of the L-shaped baffle 51, and when they coincide with the through hole, enter the cavity between the first inserting plate 272 and the second inserting plate 273 for storage;

[0106] Furthermore, when the lower barrel 53 rotates, the toothed rack 58 engaged through the tooth groove opened on its outer wall moves upward, and then the movable rod 59 is synchronously driven to move upward, so that the fertilizer and vegetable seeds in the cavity can be moved. When the reset rod 55 slides into the wedge-shaped groove 57, the spring piece 56 will push the reset rod 55 to deflect upward, thereby pushing the reset rod 55 to move upward, thereby pushing the round rod 54 and pushing the lower barrel 53 to reset. In the process of resetting, the meshing drive rack 58 moves downward, so that the fertilizer and vegetable seeds can be moved through the movable rod 59, avoiding internal blockage and promoting feeding.

[0107] The present invention provides a vegetable planting and sowing device. There are many methods and approaches for implementing this technical solution. The above is only a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Any components not specified in this embodiment may be implemented using existing technologies.
