Description

Spoon formula takes to plant and combines feed mechanism for seed with piston bundle cave

Technical field

The invention belongs to agricultural machinery, relates generally to a kind of mechanical spoon formula and takes kind of the bunch planting operation that cave is pricked with piston Feed mechanism for seed.

Background technology

Bunch planting seeding is a kind of new agricultural process planting technology for occurring in recent years, due to its have seeding accuracy it is high, to kind of a bed The features such as soil disturbance amount is small, energy consumption is relatively low, the application of the technical method is paid close attention to by people.At present, to adapt to and meet The hill-drop feed run of bundle cave seeding agriculture requirement is in research and development, and structure type is various.But, due to structure design in terms of lack Fall into, hill-drop feed run also has that cavitation quality is low, prick cave with sowing poor synchronization, bunch planting quality, and to be difficult guarantee, hole former easy The problem of hilling, restricts and limits the popularization and application of bunch planting seeding new agricultural process technical method.

The content of the invention

The problem that the purpose of the invention exists aiming at above-mentioned prior art, with reference to the reality that current agricultural is produced Need, design a kind of spoon formula and take and kind prick cave with piston and combine feed mechanism for seed, reach good cavitation quality, bundle cave and seeding synchronism it is good, Bunch planting quality is high, use the few purpose of reliability, failure.

What the purpose of the invention was realized in：Sealing is fixedly mounted with left cover on cylindrical outer barrel body left part, Opened up on the left cover into kind of a mouth, sowing port is opened up in the cylindrical outer barrel body barrel bottom side, in the left cover Slideway inner ring is fixedly mounted with interior sidewall surface, cylindrical inner barrel rotatably inserts configuration wall and slideway in cylindrical outer barrel body In the annular slide track constituted between inner ring outside wall surface, right cover plate for sealing is packed on cylindrical inner barrel right part, in cylinder Kind of a mouth is opened up out on inner barrel barrel, is held kind of a pipe and is packed in cylindrical inner barrel interior sidewall surface, it is described to hold kind of pipe and go out kind of a mouth Connection, takes kind of a spoon and is fitted on appearance kind pipe medial end, and drive shaft is inserted on left cover and right cover plate successively, the drive shaft With left cover in rotatable cooperation, the drive shaft is in secure fit with right cover plate, outside the cylindrical outer barrel body bottom side Upper installation seed spout, the seed spout is connected with sowing port, and the bundle cave that is fixedly mounted with being interconnected on the seed spout bottom is lived Plug tube, pricks moving up and down being fitted in of cave piston and pricks in the piston cylinder barrel chamber of cave, opens up vertical on the bundle cave piston cylinder barrel To strip gap, the piston pin inserting that can slide up and down is being stood in strip gap, and the inner end of the piston pin is lived with cave is pricked Plug is fixedly mounted with, the eccentric setting link pin on the right cover plate, and the upper and lower end portion of connecting rod is hinged with link pin and piston pin respectively Connect, so far composition spoon formula takes to plant and combines feed mechanism for seed with piston bundle cave.

The invention takes to plant using spoon formula pricks cave assembled scheme with piston, realizes and takes kind of bale-out kind and bundle cave piston bundle Cave seeding is worked continuously, and structure is novel, simple, reasonable, and cavitation quality is good, and bundle cave is good with seeding synchronism, and bunch planting quality is high, makes With reliability, failure is few, for the popularization and application of bunch planting sowing agronomic technique provide technical support.

Specific embodiment

The invention embodiment is described in detail below in conjunction with the accompanying drawings.A kind of spoon formula takes to plant pricks cave group with piston Feed mechanism for seed is closed, sealing is fixedly mounted with left cover 2 on the left part of cylindrical outer barrel body 1, is opened up on the left cover 2 into kind of mouth 16, Sowing port 17 is opened up in the barrel bottom side of the cylindrical outer barrel body 1, is fixedly mounted with slideway in the interior sidewall surface of the left cover 2 Circle 4, rotatably inserting configures the structure between the internal face of cylindrical outer barrel body 1 and the outside wall surface of slideway inner ring 4 to cylindrical inner barrel 5 Into annular slide track in, right cover plate 14 sealing be packed on the right part of cylindrical inner barrel 5, on the barrel of cylindrical inner barrel 5 Kind of mouth 6 is opened up out, is held kind of a pipe 13 and is packed in the interior sidewall surface of cylindrical inner barrel 5, kind of the pipe 13 that holds is connected with kind of mouth 6 is gone out, Take kind of spoon 15 to be fitted on the appearance kind medial end of pipe 13, drive shaft 3 is inserted on left cover 2 and right cover plate 14 successively, the drive With left cover 2 in rotatable cooperation, the drive shaft 3 is in secure fit with right cover plate 14 to moving axis 3, in the cylindrical outer barrel body Seed spout 7 is installed in 1 bottom side on outside, and the seed spout 7 is connected with sowing port 17, mutually interconnected on the bottom of the seed spout 7 Logical is fixedly mounted with bundle cave piston cylinder 8, pricks moving up and down being fitted in of cave piston 9 and pricks in the barrel chamber of cave piston cylinder 8, is lived in the bundle cave Opened up on the barrel of plug tube 8 and stood to strip gap 18, the inserting that can slide up and down of piston pin 10 is being stood in strip gap 18, described The inner end of piston pin 10 with prick cave piston 9 be fixedly mounted with, the eccentric setting link pin 12 on the right cover plate 14, connecting rod 11 it is upper, Bottom is hinged with link pin 12 and piston pin 10 respectively.

Operation process is：Cylindrical outer barrel body 1, seed spout 7, bundle cave piston cylinder 8 are maintained static, and drive shaft 3 passes through right cover Plate 14 drives cylindrical inner barrel 5 to rotate, and carries out taking kind when taking kind of spoon 15 and turning to bottom with cylindrical inner barrel 5, is taking During kind of spoon 15 is by lower rotation to top, takes unnecessary seed in kind of spoon 15 and drop, remain in the kind taken in kind of spoon 15 Subflow enters to hold in kind of pipe 13, and when holding kind of a pipe 13 and turning to the position of sowing port 17, seed passes through kind of mouth 6, sowing port 17 and Enter in seed spout 7, when bottom of the seed movement to seed spout 7, prick cave piston 9 and penetrate in soil, block the outlet of seed, with The rotation of cylindrical inner barrel 5, in the case where connecting rod 11, piston pin 10 are pulled, cave piston 9 is pricked and is being pricked in cave piston cylinder 8 and vertical To the lower upward sliding of the control of strip gap 18, the seed in seed spout 7 enters to be pricked in the following side of cave piston cylinder 8, and seed falls into cave In hole.
