Semiautomatic machine for transplanting vegetable seedlings on two rows

Abstract

The invention relates to a semiautomatic machine for transplanting vegetable seedlings on two rows. According to the invention, the machine consists of a power transmission subsystem (STP) taking the mechanical torque from a motorized cultivator (1) by means of a cardan shaft (2), a conical reduction gear (201), shafts (202 and 203), Gall chain transmissions (204 and 205), conical reduction gears (206 and 207) with vertical shaft which transmit the mechanical energy to Gall chain transmissions (208 and 209) with attachments supporting the seedling feed cups, where the transmissions (204 and 205) also drive some chambers (212 and 213) which, by means of some arms (214 and 215), drive a mechanism consisting of two articulated levers (218 and 219), a hole digging subsystem (SSG) for seedling planting which consists of said articulated lever mechanisms (218 and 219) supporting the cups (220), each such cup having two cells (221 and 222) to make the holes for planting the seedlings, a seedling feeding subsystem (SAR) consisting of two transport systems (250 and 251) with two Gall chain transmissions (208 and 209) with attachments supporting seedling feed and transport cups (261), a distance adjusting subsystem (SRD) which adjust the distance between seedlings by means of a transmission (111) of screw-nut type which moves the wall of a case (109) along some guides (110) which is then locked by some rectangular collars (124) while also needing the movement of pressing rollers according to the set distance between the rows by the axial movement of a mobile carrier (127) in respect of a fixed carrier (126), as well as a subsystem (SRI) for adjusting the working height of the equipment by the control of hydraulic cylinders (107) acting on some metallic articulated supports (105 and 106) which support the side wheels (103 and 104), where, for different widths of the planting crops, the displacement of said metallic supports (105 and 106) articulated on a cross member (100) of the metallic frame is also required and, for changing the distance between the planting pockets on a row, the ratio of the changing wheels of the two Gall chain transmissions (204 and 205) needs to be changed.
