Example 1
A plurality of seed outlets 403 are uniformly formed in the outer circular surface of the seed metering disc 4, a plurality of axial channels 401 are formed in the end surface of the seed metering disc 4 in a ring-shaped array, the axial channels 401 penetrate through the end surface of the seed metering disc 4 front and back and are arranged in one-to-one correspondence with the seed outlets 403, then radial channels 402 are formed between the seed outlets 403 and the axial channels 401 which correspond to each other, the radial channels 402 are radially outwards closed from one side close to the circle center in the design process, so that the radial channels 402 have a larger seed receiving area, and then the seeds are quantitatively discharged through the closed ends and the seed outlets 403. In addition, in order to ensure that the seed metering disc 4 can be stably mounted on the end face of the seed suction roller 6, an annular inner wall 601 is arranged at one end, connected with the seed metering disc 4, of the seed suction roller 6, stability of connection between the seed suction roller 6 and the end face of the seed metering disc 4 can be ensured through tight fit between the annular inner wall 601 and the end face of the seed metering disc 4 and fastening action of the screw 5, and meanwhile, a through hole 602 which is consistent in shape and aligned with the axial channel 401 is formed in the annular inner wall 601.
An inoculation box 2 capable of moving along the axial direction of the seed metering device is arranged in each axial channel 401, and an inoculation groove 201 aligned with the radial channel 402 is arranged on the inoculation box 2. In order to facilitate the insertion of the inoculation box 2 into the axial channel 401, the inoculation box 2 is assembled in a sectional manner, so that the inoculation box is formed by fixedly connecting a front half section provided with an inoculation groove 201 with a rear half section of a non-grooved design through a connecting piece such as a bolt. At the same time, a baffle plate 202 is arranged at the end part of the inoculation box 2 close to the seed sucking roller 6, so that the situation that the inoculation groove 201 is misplaced with the radial channel 402 due to excessive movement of the inoculation box 2 in the axial channel 401 is avoided. A plurality of groups of suction holes 603 are uniformly formed on the circumferential surface of the seed suction drum 6, and when one end of the inoculation box 2 moves axially into the seed suction drum 6, the suction holes 603 on the seed suction drum 6 are aligned with the inoculation groove 201, and at this time, the seed suction drum 6 can throw adsorbed seeds into the inoculation groove 201 when performing a seed placing operation. Meanwhile, in order to ensure that only axial movement and no relative rotation occur when the inoculation box 2 moves in the axial passage 401, the sectional shapes of the axial passage 401 and the inoculation box 2 are both arranged in a arch shape, and the inoculation groove 201 is opened on the flat end face of the inoculation box 2.
The end part of the inoculating box 2 far away from the seed sucking roller 6 is connected with a pulley seat 8, a pulley 9 is rotatably connected to the pulley seat 8 through a pin shaft, a spring seat 404 is arranged at the end part of an axial channel 401 far away from the seed sucking roller 6, and a spring 10 is sleeved on the inoculating box 2 between the spring seat 404 and the pulley seat 8. In addition, an arc protrusion 11 is fixed on the inner wall of the seed metering device shell 1 near one side of the pulley 9, and the arc protrusion 11 and a plurality of seed boxes 2 are positioned on the same circular line, so that the pulley 9 at the end part of the seed box 2 can be contacted with the arc protrusion 11 one by one in the rotation process of the seed metering disc 4, and the whole seed box 2 can be pushed and pulled back to one end of the seed suction roller 6 along the axial channel 401 under the action of the spring 10.
In a specific design process, referring to fig. 8, the arc protrusion 11 is formed by sequentially connecting a push-off section 111, a far repose angle section 112 and a return section 113. In the rotation process of the seed sucking roller 6, when the pulley 9 at the end part of the inoculation box 2 is not contacted with the arc protrusion 11, the left end surface of the baffle plate 202 at the end part of the inoculation box 2 is tightly attached to the annular inner wall 601 of the seed sucking roller 6 under the natural action of the spring 10, so that the inoculation groove 201 is aligned with the radial channel 402; when the pulley 9 at the end of the inoculating box 2 is contacted with the pushing section 111 on the arc protrusion 11, the pushing section 111 drives the inoculating box 2 and compresses the spring 10, so that the inoculating box 2 moves along the axial channel 401 towards the seed sucking roller 6 until the inoculating groove 201 on the inoculating box 2 is aligned with the sucking hole 603 on the inner sucking roller 6; when the pulley 9 at the end of the inoculation box 2 is turned into the far repose angle section 112, the inoculation groove 201 and the suction hole 603 on the seed suction roller 6 are kept aligned for a period of time and synchronously rotate; when the pulley 9 at the end of the inoculation box 2 is turned into the return section 113, the inoculation box 2 is reversely pulled back into the seed metering disc 2 along the axial channel 401 under the action of the elastic force of the spring 10 until the left end face of the baffle plate 202 of the inoculation box 2 is tightly attached to the inner wall 601 of the seed suction roller 6, and the inoculation groove 201 is aligned and communicated with the radial channel 402 on the seed metering disc 4.
In the running process of the inner seed guiding component of the inner suction drum type precise hole sowing seed metering device, the seed suction drum 6 is driven by the seed metering shaft 7 to drive the seed metering disc 4 to synchronously rotate, and seeds are adsorbed by utilizing the negative pressure adsorption effect of the suction holes 603 to synchronously rotate when the seed suction drum 6 rotates in the seed metering device shell 1.
When the suction hole 603 with the seeds adsorbed thereon and the inoculation box 2 corresponding to the suction hole 603 rotate to the upper end of the seed metering device shell 1, the pulley 9 corresponding to the end part of the inoculation box 2 starts to act with the arc protrusion 11, when the pulley 9 rotates to the far repose angle section 112, the inoculation groove 201 on the inoculation box 2 faces the suction hole 603 rotating to the upper side, and then seeds fall into the inoculation groove 201 under the action of self gravity by cutting off the negative pressure of the seeds adsorbed on the suction hole 603.
The seed box 2 then enters the return section 113 during rotation with the seed plate 4 and is gradually pulled back into the axial channel 401 by its spring 10 until the seed slot 201 is aligned with the radial channel 402. When the inoculation box 2 rotates from the upper end to the lower end of the seed metering device shell 1, seeds in the inoculation groove 201 fall into the radial channel 402, and when the corresponding seed outlet 403 of the radial channel 402 is communicated with the seed metering channel 101 on the seed metering shell 1, the seeds in the radial channel 402 are quantitatively discharged from the whole seed metering device through the seed metering channel 101 in a hole.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
