Description

Technical Field

[0001] The invention relates to the technical field of sowing devices, and in particular to a vegetable seedling raising and sowing device. Background Art

[0002] Vegetables refer to a type of plants or fungi that can be cooked and made into food. Vegetables are one of the indispensable foods in people's daily diet. Vegetables can provide a variety of nutrients such as vitamins and minerals that are necessary for the human body. The nutrients of vegetables mainly include minerals, vitamins, fiber, etc. The higher the content of these substances, the higher the nutritional value of vegetables. In addition, the water content and dietary fiber content in vegetables are also important nutritional quality indicators. Generally, vegetables with high water content and low dietary fiber are more tender and have higher edible value. There are also many phytochemicals in vegetables that are recognized as beneficial to human health, such as carotenoids, dipropylene compounds, methyl sulfide compounds, etc. Many vegetables also contain unique trace elements, which have special health benefits for the human body.

[0003] In the existing vegetable seedling raising, a sowing device is usually used for sowing to avoid the problems of low efficiency and high cost of manual sowing. For example, Chinese patent announcement No. CN221634385U discloses "a vegetable seedling raising and sowing device", in which a rotating shaft and a roller cooperate to drive a sowing plate to rotate, so that the vegetable seeds in the sowing groove are evenly sprinkled on the land; a U-shaped sowing plate, a soft paddle and a sowing plate cooperate to temporarily store vegetable seeds, and the vegetable seeds can be placed in the sowing groove; a push handle facilitates people to push the device forward;

[0004] However, in actual use, due to the different sizes of seeds of different vegetables, the temporary storage space required for the same number of seeds is also different. For example, the seeds of the Cruciferae family are generally smaller, while the seeds of Cucurbitaceae vegetables are generally larger. When the space in the sowing trough remains unchanged, the number of seeds stored inside varies greatly, resulting in waste due to excessive sowing during sowing, and easily leading to insufficient growth space, affecting ventilation and light, easily causing diseases, and reducing growth rate and quality. When the seeds are larger, they are sown sparsely, which easily leads to no seedlings at the sowing position, affecting the yield of vegetable seedlings. Summary of the invention

As sowing progresses, the number of seeds gradually decreases, and the output end of the first spring telescopic rod 923 gradually extends out, thereby changing the movement trajectory of the pushing plate 921 and gradually approaching the dividing tray 61, so that a small number of seeds are still accumulated near the dividing tray 61 for easy digging.

[0050] In detail, in the present embodiment, the power assembly 91 includes a turntable 912 having a cam groove 911 fixedly connected to the connecting shaft 62, a transmission rod 913 which cooperates with the cam groove 911 is rotatably provided on the connecting rod 924, and a guide seat which cooperates with the transmission rod 913 is fixedly provided on the outer wall of the storage box 4. When the connecting shaft 62 drives the distributing plate 61 to rotate, the turntable 912 is driven to rotate. When the distributing cup 64 moves to near the pushing plate 921, the cam groove 911 cooperates with the transmission rod 913 to drive the pushing plate 921 toward the position of the distributing plate 61, so that the seeds are accumulated near the distributing plate 61.

[0053] In this embodiment, the power assembly 91 also includes a driving gear 914 fixedly connected to the driving shaft 933. The outer wall of the turntable 912 is provided with teeth. A transmission gear 915 is meshingly connected between the driving gear 914 and the turntable 912. The transmission gear 915 is driven to rotate by the turntable 912, thereby driving the driving gear 914 and the driving shaft 933 to rotate, thereby providing power for the driving shaft 933.

[0054] Working mode: When working, a plurality of material distribution chambers 41 are arranged in the storage box 4, and each material distribution chamber 41 is provided with a material distribution mechanism 6 and a material guide mechanism 7, which can be used to sow seeds of different volumes respectively, and the material distribution mechanism 6 can be adapted to seeds of different volumes by replacing material distribution cups 64 of different specifications;

[0055] When the vegetable seedling sowing device moves, the roller 2 and the rotating shaft 3 rotate accordingly, and the connecting shaft 62 is driven to rotate through the chain transmission structure 8, and then the distribution plate 61 is driven to rotate, so that the distribution cup 64 digs the seeds and transports them to the guide frame 71. The seeds enter the guide frame 71 along the guide portion 642 and are sown along the guide hopper 76 and the sowing tube 12 below the guide frame 71. When the distribution cup 64 moves to the vicinity of the push plate 921, the cam groove 911 cooperates with the transmission rod 913 to drive the push plate 921 toward the distribution plate 61. The seeds are pushed to the position, so that the seeds are accumulated near the distribution plate 61, which is convenient for digging. The transmission gear 915 is driven to rotate by the turntable 912, which in turn drives the driving gear 914 and the driving shaft 933 to rotate, and the toggle part 935 rotates accordingly. When it contacts the force plate 936, the force plate 936 and the knocking piece 932 are driven to move backward, and the second spring telescopic rod 934 is compressed by force. When the toggle part 935 is separated from the force plate 936, the second spring telescopic rod 934 drives the knocking piece 932 to move forward to knock the sowing tube 12;
