[0002] A seeder is a planting machine that sows crop seeds. When currently planting vegetables such as Shanghai green and Guangdong choy sum, they are generally sown through a crop seeder, which improves sowing efficiency, saves manpower, and reduces the planting costs of vegetables such as Shanghai green and Guangdong choy sum.

[0003] In a Chinese patent with publication number CN217011742U, an automatic sowing device for Shanghai green planting is disclosed, in which a blocking plate is provided. When the sowing spacing needs to be adjusted, the adjusting block is rotated through the adjusting groove, and the rotation of the adjusting block drives the rotating rod and the first bevel gear to rotate, so that the first bevel gear rotates the second bevel gear to rotate, and the rotation of the second bevel gear drives the threaded rod to rotate. The rotation of the threaded rod causes its moving rod to drive the blocking plate to move outward, so that the blocking plate closes the sowing port, thereby forming a spacing between multiple sowing ports, thereby completing the adjustment of the sowing spacing, so that it can The sowing spacing is adjusted according to the different sowing soils, so that the Shanghai green will not grow in piles when sown, ensuring that each seed can absorb nutrients in the soil, thereby ensuring its germination and subsequent growth effects; however, when the above-mentioned automatic sowing device for Shanghai green is in use, the sowing tube is connected to the sowing box, and a large number of seeds in the sowing box are easily dropped directly into the sowing tube at one time, which will cause the seeds to jam the sowing ball, making the sowing ball unable to rotate or damaged, affecting the sowing efficiency, and increasing the maintenance cost of the equipment. Therefore, we propose an adjustable crop seeder. Utility Model Content

[0026] A sowing box 1 is provided with two furrowing plows 2 at the bottom of the sowing box 1, and two sowing tubes 3 for sowing crop seeds are also provided at the bottom of the sowing box 1.

[0027] As can be seen from the above, when in use, the seed box 1 is first connected to the external tractor, and the furrowing plow 2 is inserted into the ground. Then the seed box 1 moves under the action of the tractor, so that the seed box 1 drives the furrowing plow 2 to plow a deep furrow on the ground. At this time, the seeds inside the seed box 1 are sown in the deep furrow through the sowing tube 3, and the seeds are buried, thereby completing the sowing of the Shanghai green.

[0028] refer to Figure 1-Figure 4 As shown, a feeding device 4 is provided between the two sowing tubes 3, and the feeding device 4 includes a lifting block 403, both ends of the lifting block 403 are provided with motors 404, and the output shafts of the two motors 404 are provided with transmission blocks 405, and a transmission mechanism is provided between the transmission block 405 and the sowing tube 3;

[0029] The transmission mechanism includes a connecting shaft rotatably mounted on the top of the transmission block 405, a positioning block 407 is provided at one end of the connecting shaft away from the transmission block 405, a liftable push plate 408 is provided on the top of the positioning block 407, a liftable blocking block 410 is provided on the top of the push plate 408, and the blocking block 410 is inserted at the top of the sowing tube 3; an extension block is fixed at the bottom of the positioning block 407, the extension block is rotatably connected to the end of the connecting shaft away from the transmission block 405, a groove is provided at the top of the positioning block 407, the bottom of the push plate 408 is installed in the groove, a rotating shaft is provided inside the groove, and the bottom of the push plate 408 is sleeved on the rotating shaft; a baffle is provided on the top of the push plate 408, two feeding ports are symmetrically provided on the baffle, and the diameter of the baffle is equal to the diameter of the blocking block 410; a protrusion is fixed at the bottom of the blocking block 410, the protrusion is a truncated cone with a wide top and a narrow bottom, and the bottom diameter of the protrusion is smaller than the inner diameter of the sowing tube 3;

[0030] By adopting the above technical solution:

[0031] When in use, the output shaft of the motor 404 drives the transmission block 405 to rotate, the transmission block 405 drives the connecting shaft to rotate, the connecting shaft drives the positioning block 407 to rotate, and the positioning block 407 is limited by the rotating shaft and the push plate 408, so that the positioning block 407 reciprocates around the rotating shaft, and then the transmission block 405 drives the positioning block 407 to move up and down through the connecting shaft, and the positioning block 407 drives the push plate 408 to move vertically up and down through the rotating shaft, and the push plate 408 pushes the blocking block 410 to move vertically up and down, so that the raised portion of the blocking block 410 moves above the sowing tube 3, and then the seeds inside the sowing box 1 are repeatedly reciprocated through the raised portion. Small amounts of seeds enter the inside of the sowing tube 3 multiple times, so as to avoid the problem that a large amount of seeds inside the sowing box 1 are easily dropped directly into the sowing tube 3 at one time, causing the seeds to jam the sowing ball, thereby improving the sowing efficiency of crops.

[0032] In addition, refer to Figure 1-Figure 4 As shown, a threaded rod 401 is fixed to the top of the lifting block 403, a rotatable threaded sleeve 402 is provided at the bottom of the seed box 1, and a threaded groove matched with the threaded rod 401 is provided in the middle of the threaded sleeve 402; a slider 406 is fixed to the output shaft of the motor 404, a sliding groove matched with the slider 406 is opened on the transmission block 405, and a spring 409 is provided between the slider 406 and the sliding groove.

[0033] By adopting the above technical solution:

[0034] When in use, the threaded sleeve 402 is rotated, and the thread groove of the threaded sleeve 402 cooperates with the threaded rod 401, so that the threaded rod 401 moves up and down reciprocatingly, and the threaded rod 401 drives the lifting block 403 to move up and down reciprocatingly, and the lifting block 403 drives the motor 404 to move up and down reciprocatingly, and the motor 404 drives the slider 406 to move vertically up and down reciprocatingly. When the motor 404 moves to the bottom of the slide groove of the transmission block 405, the motor 404 drives the transmission block 405 to rotate through the slider 406, and the transmission block 405 drives the positioning block 407 to rotate through the connecting shaft at a small angular velocity, so that the positioning block 407 drives the push plate 408 to move up and down a small distance, so that the push plate 408 pushes the blocking block 410 to move up and down a small distance, thereby realizing the lifting of the protrusion inside the sowing tube 3, so that the seeds inside the sowing box 1 stop feeding;

[0035] At the same time, when the motor 404 moves to the top of the slide groove of the transmission block 405, the motor 404 drives the transmission block 405 to rotate through the slider 406, and the transmission block 405 drives the positioning block 407 to rotate through the connecting shaft at a large angular velocity, so that the positioning block 407 drives the push plate 408 to rise and fall a large distance, and the push plate 408 pushes the blocking block 410 to rise and fall a large distance. At this time, the protrusion moves to the top of the sowing tube 3, so that the seeds inside the sowing box 1 can enter the inside of the sowing tube 3 in large quantities and quickly, so that people can adjust the feeding speed of the seeds inside the sowing box 1 into the sowing tube 3, further improving the practicality of the device.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
