Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A through hole type seed/fertilizer sowing amount adjustable sowing monomer is characterized in that a cylinder type outer shell 9 is fixedly arranged on a monomer shaft 12 through a spoke rod 17, a through hole 10 is formed in the cylinder wall of the cylinder type outer shell 9, and a locking grooved pulley 1 and a driving wheel 13 are respectively and fixedly arranged on the left end part and the right end part of the monomer shaft 12; an adjusting driving circular plate 6 and an adjusting driven circular plate 15 are respectively arranged on the left end part of the single body shaft 12 on the inner side part of the locking grooved wheel 1 and the right end part of the single body shaft on the inner side part of the driving wheel 13 in a radial and axial positioning and circumferential rotating way, an involute arc hole 8 and a linear strip hole 16 are respectively arranged on the adjusting driving circular plate 6 and the adjusting driven circular plate 15 along the radial direction, the left end and the right end of the adjusting rod 7 are respectively movably supported and inserted in the involute arc hole 8 on the adjusting driving circular plate 6 and the linear strip hole 16 on the adjusting driven circular plate 15, a radial strut 14 is arranged on the adjusting rod 7, a seeding quantity adjusting chock 11 is arranged on the outer end part of the radial strut 14, the seeding rate adjusting plug 11 is in radial movable insertion fit with the through hole 10 on the cylindrical shell 9, and a groove pit with variable volume is formed on the wall of the cylindrical shell 9; the outer side surface of the adjusting driving circular plate 6 is fixedly provided with a locking shell 4, the locking pin 2 can be radially installed on the locking shell 4 in a pulling and moving mode, the pressure spring 3 is sleeved on the locking pin 2, one end of the pressure spring 3 is axially positioned on the locking pin 2, the other end of the pressure spring 3 is in contact fit with the locking shell 4, the inner end of the locking pin 2 is in clamping and locking fit with the locking grooved wheel 1, and the outer end of the locking pin 2 is located on the outer side part of the locking shell 4 and is fixedly provided with a hand lever 5.
When the seed or fertilizer is spread, the external rotary power drives the cylinder type outer shell 9 to rotate through the driving wheel 13, the single shaft 12 and the spoke rod 17, and simultaneously, the locking pin 2 rotates together with the clamping and locking cooperation of the locking sheave 1 which rotationally locks on the single shaft 12, and simultaneously drives the sowing quantity adjusting plug 11 to rotate in the same rotating speed and the same direction in the through hole 10 on the cylinder type outer shell 9 through the locking shell 4, the adjusting driving circular plate 6, the adjusting driven circular plate 15, the adjusting rod 7 and the radial strut 14 in sequence, so that the seeds or the fertilizer filled in the groove pit formed by the sowing quantity adjusting plug 11 and the through hole 10 on the cylinder type outer shell 9 from the outer side part of the cylinder type outer shell 9 are spread, and the operation is completed. When the seed or fertilizer sowing amount is adjusted according to the operation requirement, the single shaft 12 stops rotating, the hand lever 5 is held by a hand to be lifted and pulled outwards in the radial direction, the locking pin 2 is separated from the clamping and locking matching with the locking grooved wheel 1, the locking shell 4 is rotated clockwise or anticlockwise by the hand to drive the adjusting driving circular plate 6 to rotate, under the driving control of the involute arc hole 8 on the adjusting driving circular plate 6 and the matching of the linear strip hole 16 on the adjusting driven circular plate 15, the adjusting rod 7 drives the sowing amount adjusting plug 11 to do radial telescopic movement in the through hole 10 through the radial support rod 14, the radial overlapping depth of the sowing amount adjusting plug 11 inserted in the through hole 10 is changed, namely the volume size of the groove is changed, and the seed or fertilizer sowing amount adjustment is realized: the overlapping insertion depth is large, and the seeding amount is small; the overlapping insertion depth is small and the seeding amount is large.
