The working principle of the corn hill planter is as follows: corn seeds are added into the seed box 302 in front of the sowing box 3 through the feeding pipe 306 on the sowing box 3, the seeding box 302 cannot be filled with the corn seeds, and the seed box 302 is preferably made of transparent plastic, so that the addition amount of the corn seeds can be conveniently seen; corn seeds are stacked at the bottom of the seed box 302; the roller 1 is pushed to advance, the roller 1 drives the roller shaft 103 to synchronously rotate, the roller shaft 103 synchronously rotates, and the single seed taking device 4 in the seeding box 3 also synchronously rotates, and the seeding box 3 is arranged on the roller shaft 103 through a bearing 304, so that the seeding box 3 cannot rotate together; after the seed taking spoon 408 on the seed taking plate 401 in front of the single seed taking device 4 rotates to the bottom of the seed box 302, at least one corn seed is grabbed, the corn seed is clamped in the spoon head 409 and the first annular groove 309 of the seed taking spoon 408, the seed taking spoon 408 continuously ascends along the first annular groove 309, because the spoon head 409 can only contain one corn seed, redundant seeds can fall after rotating to a certain angle, the seed taking spoon 408 is ensured to take only one seed, and the groove-shaped spoon head 409 can ensure that the seed is difficult to fall off; the seed taking spoon 408 rotates to the second gap 308 at the upper part of the separation plate 303, and seeds fall into the seed discharging groove 405 exposed out of the second gap 308 from the spoon head 409; the seed discharging plate 402 rotates along with the roller shaft 103 synchronously, when the seeds falling into the seed discharging groove 405 rotate along with the seed discharging plate 402 to the first notch 305 under the mechanical box 301, the seeds are discharged from the first notch 305 and fall into the seed collecting funnel 5, then the seeds are conveyed into the duckbilled seed discharging shell 201 through the seed collecting funnel 5, and then the seeds are sowed into the ground from the duckbilled seed discharging shell 201.

Example 1

According to practical experience, in mountainous and hilly lands, the scientific planting experience of corn is that 4000 plants are sown per mu, generally the row spacing is 42cm, and the plant spacing is about 40 cm; therefore, the arc length of the adjacent duckbilled seed discharging openings 2 on the roller 1 is preferably kept at about 40cm, and therefore 3 or 4 duckbilled seed discharging openings 2 are preferably arranged on the roller 1, so that the size of the roller 1 is not too large, and the requirement of manual operation in the ground can be well met.

Example 2

The arc length of the adjacent duckbilled seed discharging openings 2 on the roller 1 is about 40cm, 3 duckbilled seed discharging openings 2 are uniformly arranged on the roller 1, the diameter of the roller 1 is about 38 cm, meanwhile, 3

seed collecting hoppers

5 and 3 seed taking spoons 408 are correspondingly arranged, each duckbilled seed discharging opening 2 corresponds to one seed collecting hopper 5 and one seed taking spoon 408, and the duckbilled seed discharging openings are basically in the same radial direction.

Example 3

As shown in fig. 10, the arc length of the adjacent duckbilled discharging openings 2 on the roller 1 is about 40cm, 4 duckbilled discharging openings 2 are uniformly arranged on the roller 1, the diameter of the roller 1 is about 51 cm, meanwhile, 4 seed collecting funnels 5 and 4 seed taking spoons 408 are correspondingly arranged, each duckbilled discharging opening 2 corresponds to one seed collecting funnel 5 and one seed taking spoon 408, and the duckbilled discharging openings are basically in the same radial direction.

As shown in fig. 18, the corn hill-drop planter can be designed into a multi-row planting structure, so that the planting efficiency is improved, namely, at least 2 corn hill-drop planters are arranged in parallel, adjacent corn hill-drop planters are connected together by at least one assembling connecting rod 7, and the distance between the adjacent corn hill-drop planters is controlled by the length of the assembling connecting rod 7, so that the row spacing of corn planting is controlled.

As shown in fig. 19, the connection between adjacent corn hill-drop planters is preferably detachable, so that the user can flexibly assemble the corn hill-drop planters according to the needs, and the detachable structure can be: the connecting main rod 602 of the hand push rod 6 of each corn hill planter is provided with a short connecting rod 8, and is matched with an independent assembling connecting rod, the assembling connecting rod is a hollow rod, the short connecting rod can be inserted into the assembling connecting rod, a pin hole is formed in the joint of the short connecting rod and the assembling connecting rod, and a pin piece penetrates through the pin hole to be fixed (as shown in fig. 20).
