[0032] The bottom pipeline of fertilizer box cover 5 is connected with fertilizer discharge hopper 9, and the bottom pipe opening of fertilizer discharge hopper 9 is connected with fertilizer arc-shaped pipe 10. Bottom support plate 11 is welded below device main frame body 1, and the transverse center end of bottom support plate 11 is embedded with bend bracket fixed main cross beam 12, and L-shaped plate 13 is connected below bend bracket fixed main cross beam 12, and spring buckle 14 is fixed on one side of L-shaped plate 13.
[0033] Spring buckle 14 is connected in the clamping groove of spring buckle 14, and fertilizing and soil plowing damping spring 15 is connected with the rear cross bar of bottom support plate 11 at the tail end.
[0034] Seed storage box 2 bottom is installed with seed stirring wheel 18, and the inlet end of seed discharge pipe 8 is provided with planting seed inlet 19, and seed stirring wheel 18 corresponds with the bottom planting seed inlet 19. Stirring wheel rotating shaft 20 is transversely penetrated in the inside of seed stirring wheel 18, and driven gear 21 is embedded on one side of stirring wheel rotating shaft 20, and driven gear 21 is located on the right side of the top end of device main frame body 1.
[0035] The driven gear 21 is connected with the driven chain 22 on the outer edge, and the other end of the driven chain 22 is connected with the driving gear 23, and the driving gear 23 is nested with the driving wheel 24 on the inner side of the outer disc gear. The moving wheel 25 is rotatably installed below the bottom support plate 11, the inner side of the moving wheel 25 is provided with a linkage gear, and the linkage gear is nested with the driving wheel 24. The front end chain of the fertilizer arc-shaped pipe 10 is provided with a covering rod 26, and the tail end of the equipment main frame body 1 is provided with a farm machine connecting frame 27.
[0036] The working principle of the intelligent planting and fertilizing integrated equipment is as follows: the equipment is connected with the farm machine through the farm machine connecting frame 27, and the farm machine provides power and drives the equipment to move. During the movement of the equipment, the moving wheel 25 below the bottom support plate 11 rotates, and the linkage gear in the inner side of the moving wheel 25 drives the driving gear 23 to rotate through the driving wheel 24. The driving gear 23 drives the driven gear 21 to rotate through the driven chain 22, and the seed stirring wheel 18 on the stirring wheel shaft 20 rotates.
[0037] When the seed stirring wheel 18 rotates, the seeds in the seed storage box 2 are stirred into the planting seed feeding port 19, the seeds fall into the land through the seed discharge funnel 7 and the seed discharge pipe 8, and the seeding operation is realized.
[0038] At the same time, the fertilizer in the fertilizer storage box 4 falls through the fertilizer discharge funnel 9 and the fertilizer arc-shaped pipe 10. Below the fertilizer arc-shaped pipe 10, the soil digging bent piece 17 on the bent piece frame fixed to the front end of the main cross beam 12 of the bent piece frame digs the soil when the equipment moves, so that the fertilizer falls into the dug soil ditch. The covering rod 26 installed on the front end chain of the fertilizer arc-shaped pipe 10 covers the soil on the place where the fertilizer is applied, and the fertilizing and soil covering operations are completed.
[0039] During the fertilizing and soil digging process, the fertilizing and soil digging damping spring 15 is connected with the L-shaped plate 13 through the spring buckle 14, which plays a damping and buffering role, reducing the influence of vibration on the equipment during soil digging.
[0040] The working process of the intelligent planting and fertilizing integrated equipment is as follows:
[0041] 1. Preparation: open the seed box cover 3 and the fertilizer box cover 5, respectively, add seeds and fertilizer into the seed storage box 2 and the fertilizer storage box 4, and then close the box cover.
[0042] Connect the equipment with the farm machine through the farm machine connecting frame 27.
[0043] 2. Equipment start and movement: the farm machine is started, which drives the equipment to move forward. When the equipment moves, the moving wheel 25 below the bottom support plate 11 rotates.
[0044] 3. Sowing process: The linkage gear inside the moving wheel 25 drives the driving gear 23 to rotate through the driving wheel bar 24. The driving gear 23 drives the driven gear 21 to rotate through the driven chain 22. The driven gear 21 drives the seed poking wheel 18 on the poking wheel shaft 20 to rotate. The seed poking wheel 18 pokes the seeds in the seed storage box 2 into the planting seed feeding port 19. The seeds fall into the land through the seed discharge funnel 7 and the seed discharge pipe 8, completing the sowing.
[0045] 4. Fertilizing process: The fertilizer in the fertilizer storage box 4 falls through the fertilizer discharge funnel 9 and the fertilizer arc-shaped pipe 10.
[0046] 5. Soil plowing and covering process: Below the fertilizer arc-shaped pipe 10, the soil plowing curved blade 17 on the curved blade holder fixed to the front end of the main cross beam 12 plows the soil when the device moves, allowing the fertilizer to fall into the plowed soil trench. The soil covering rod 26 installed on the front end of the fertilizer arc-shaped pipe 10 then covers the soil on the fertilized place, completing the soil covering operation.
[0047] 6. Shock absorption: During the fertilizing and soil plowing process, the fertilizing and soil plowing shock absorption spring 15 connected by the spring buckle 14 plays a role in shock absorption and buffering, reducing the impact of vibration during soil plowing on the device. Through the above workflow, the intelligent planting and fertilizing integrated device can realize the integration of sowing, fertilizing, soil plowing, and soil covering, improving the efficiency and quality of planting.
[0048] Example 2: An intelligent planting and fertilizing integrated device, implementation scenario: an open farmland that needs to be planted and fertilized.
[0049] Implementation steps:
[0050] 1. The operator connects the agricultural machine connecting holder 27 at the tail end of the device main frame 1 to the agricultural machine, ensuring firm connection.
[0051] 2. Open the seed box cover 3 and the fertilizer box cover 5, and pour an appropriate amount of seeds and fertilizer into the seed storage box 2 and the fertilizer storage box 4 respectively, then close the covers.
[0052] 3. Start the agricultural machine to drive the device to move at a uniform speed in the farmland.
[0053] 4. As the device moves, the moving wheel 25 below the bottom support plate 11 starts to rotate. The linkage gear inside the moving wheel 25 drives the driving gear 23 to rotate through the driving wheel bar 24, and the driving gear 23 drives the driven gear 21 to rotate through the driven chain 22.
[0054] 5. The rotation of the driven gear 21 causes the seed poking wheel 18 on the poking wheel shaft 20 to start rotating. The seed poking wheel 18 pokes the seeds in the seed storage box 2 into the planting seed feeding port 19, and the seeds are evenly sown into the land through the seed discharge funnel 7 and the seed discharge pipe 8.
[0055] 6. At the same time, the fertilizer in the fertilizer storage box 4 enters the fertilizer arc pipe 10 through the fertilizer discharge funnel 9, and falls from the outlet of the fertilizer arc pipe 10.
[0056] 7. Below the fertilizer arc pipe 10, the soil-turning blade 17 on the curved blade holder fixed to the front end of the main cross beam 12 of the curved blade holder turns up the soil during the forward movement of the equipment, so that the fertilizer can fall into the turned-up soil trench.
[0057] 8. The soil covering rod 26 installed by chain at the front end of the fertilizer arc pipe 10 then covers the soil at the fertilized place, completing the soil covering operation.
[0058] 9. During the fertilizing and soil-turning process, the fertilizing and soil-turning damping spring 15 connected by the spring buckle 14 plays a damping and buffering role, reducing the impact of the vibration generated during soil turning on the equipment, and ensuring the stable operation of the equipment.
