[0032] Example
[0033] As a typical implementation of the present invention, please refer to Figure 1a ~ Figure 2 This embodiment discloses a secondary seeding mechanism of a drum type hole planter, which includes a cylindrical seeding body, which specifically includes a cylindrical outer side wall 1, and the inner side of the outer side wall 1 is connected The side panels, it can be understood that the side panels are ring-shaped, and the inner side of the outer side wall 1 is connected to the first side panel 6, the second side panel 7 and the third side panel 8 in total.
[0034] In this embodiment, considering the trajectory requirements of the seed 12, the first side plate 6, the second side plate 7 and the third side plate 8 are not arranged in parallel, and the first side plate 6 and the second side plate 7 are from the inner edge to The direction of the outer edge gradually moves away. It can be understood that the second side plate 7 and the third side plate 8 gradually approach from the inner edge to the outer edge to guide the seeds 12 from the entrance of the inner seed canal into the inner seed canal.
[0035] In this embodiment, the inner edges of the first side plate 6 and the second side plate 7 are connected with an inner side wall 9. Specifically, the inner edges of the first side plate 6 and the inner edges of the second side plate 7 are all welded to the inner side. The side of the wall 9 and the welding seam are continuous. A relatively closed inner seed channel 11 is formed between the first side plate 6, the second side plate 7, the inner side wall 9 and the outer side wall 1.
[0036] Please refer to image 3 , The inner seed canal 11 is directly connected with the outside through the exit 2 of the inner seed canal 11, so the inner seed canal 11 must consider the running state of the seed 12 after the inner seed canal 11 exits 2 after the inner seed canal 11 runs inside, as in the background art As mentioned, the seed 12 needs to enter the duck's bill to complete the sowing. In order to accurately enter the duck's bill, the seed 12 first needs to be decelerated in the inner seed canal 11. Therefore, a plurality of partitions 4 are evenly arranged in the inner seed canal 11. The two sides of 4 are respectively welded to connect the first side plate 6 and the second side plate 7, and the spaces between the plurality of partitions 4 are respectively named the first inner seed channel, the second inner seed channel,..., the Nth inner channel Kind of way.
[0037] After the seed 12 touches the partition 4, the speed decreases to zero, and it rotates with the seeding body to obtain a new acceleration until it shoots out through the exit 2 of the inner seed canal 11; it is understandable that as image 3 As shown in the figure, the adjacent inner seed canal 11 ensures that the end-of-movement velocity of the seed 12 in the inner seed canal 11 is reduced to zero, while the exit 2 of the inner seed canal 11 is close to the partition 4, and the seed 12 is ejected from the inner passage to the exit After that, it can be ensured that its trajectory is in the direction of centrifugal force.
[0038] The first inner seed channel 11 is provided with the first inner seed channel entrance on the second side plate 7, and the second inner seed channel is provided with the second inner seed channel entrance on the second side plate,..., the Nth inner seed channel is on the second side The board opens the Nth inner seedling entrance.
[0039] An outer seed canal 10 is formed between the second side plate 7 and the third side plate 8. A plurality of seed baffles 5 are evenly arranged in the outer seed canal 10, and the two sides of the plurality of seed baffles 5 are respectively welded to the second side plate 7 and the third side plate 8, the spaces between the multiple seed stoppers 5 are respectively named the first external seed channel, the second external seed channel,..., the Nth external seed channel.
[0040] The first external seed canal 10 is connected to the first internal seed canal through the entrance of the first internal seed canal, the second external seed canal is connected to the second internal seed canal through the entrance of the second internal seed canal,..., the Nth external seed canal The channel is connected to the Nth inner seedling channel through the entrance of the Nth inner seedling channel.
[0041] It is understandable that the position of the entrance 3 of the inner seedway 11 on the side plate is close to the seed stopper 5, so that the seeds 12 entering along the seed stopper 5 can directly enter through the entrance 3 of the inner seedway 11 The inner seedway 11. It can also be understood that, in order to facilitate the seed 12 to pass through the entrance 3 of the inner seed canal 11, the seed baffle 5 may be inclined to the direction of the inner seed canal 11.
[0042] More specifically, the seed stopper 5 is inclined to the partition 4 as a whole, and the inner end of the seed stopper 5 extends toward the inner side wall; the sidewall of the seed stopper 5 is welded to the second side plate 7 and the third side plate 8, and the weld is continuous to form a relatively closed channel.
[0043] The partition 4 has a trapezoidal shape.
[0044] On the outer side wall 1, along the rotation direction, an inner seed channel 11 exit 2 is opened on the outer side wall 1 at the front side position of the partition 4.
[0045] The inner seed canal 11, the outer seed canal 10, the partition 4, the seed stopper 5, the inlet of the inner seed canal 11, and the outlet 2 of the inner seed canal 11 are equal in number and the same as the number of hole planters to ensure seeding and seeding holes Number of correspondence.
[0046] The running process of this embodiment is, please refer to image 3 , The trajectory of seed 12 in the secondary seeding mechanism is as image 3 As shown, with the rotation of the hole planter, the seed 12 enters the outer seed canal 10 from the seeding disc, and enters the inner seed canal 11 through the entrance of the inner seed canal 11. During the upward process, the seed 12 falls into the inner seeding channel due to its own weight and the rotation of the hole planter. At the bottom of the channel 11, when the seed 12 passes the highest point and moves by its own weight to the partition 4 in the forward direction, when the seed 12 descends to the position below 1/2 of the drill, the seed 12 enters the end of the duckbill from the exit 2 of the inner seed channel 11 , Complete the second seeding.
[0047] The secondary seeding mechanism of the drum-type hole planter in this embodiment may be integrally formed, or may be a combined structure connected together, preferably by welding.
[0048] It should be understood that since the main structures of the outer side wall 1 and the inner side wall 9 are cylindrical, the centripetal side is the inner side, and the centrifugal side is the outer side. Based on this basic orientation, the inner and outer sides in this embodiment are accurately defined.
