Abstract

The utility model relates to a duplex agricultural machine which integrates fertilizer deep placement for roots, ridging between lines, mulching film covering, and film side drilling into a whole. The utility model is characterized in that a profiling mechanism, a hilling height limit device, and a film hanging structure are driven by land wheels. A profiling driving wheel is hinged with a machine frame through a profiling arm, and simultaneously, the tensioning of a driving chain is controlled by a tensioning wheel to drive a seeding apparatus to seed continuously. A hilling height limit board is arranged at the side of a hiller which is arranged on a back movable bracket. A film hanging machine frame is formed into an integraltype pi shape, and is arranged on a machine frame which is arranged between the two profiling land wheels. The utility model overcomes the defects of uneven sowing, vacant hill, breakage, uneven hilling, and uneven film covering in the prior art, and plays the predominance of increase in yield for mulching film covering and sowing.

Description

The wheat fertilizing tectorial seeder

The utility model relates to a kind of collection root deep placement chemical fertilizer, and in the ranks making ridge covering with plastic film, film-side drilling wheat or other cereal are in the compound farm working machinery-wheat fertilizing tectorial seeder of one.

Old-fashioned wheat fertilizing tectorial seeder has three big technological deficiencies in operation process.The first, play the land wheel that drives the seeding effect because of with associated components be fixed whole connection, make it cause owing to ground is uneven landing unreal or being interrupted in the middle of the sowing landing, and then form ground wheel speed speed and differ, even stall, so seeding is irregular, the disconnected bar that is short of seedling is more serious; The second, design and installation ridging height limiter not, behind the film of shop ridging highly unstable, directly the influence ridging is just wayward for speed of a motor vehicle height, inefficiency; Three, the biofilm mechanism design is unreasonable, and the shop film is inhomogeneous not whole.Reason is the independently swings separately of two ends, the biofilm frame left and right sides, in the operation when making ridge during not at the ground center membrane or meet soil block film easy secundly in shop when supporting, cause ridging on one side to cannot keep under control the phenomenon of film, the film limit influences fertilising, overlay film, seeding quality and comes annual crops in ridge central authorities when serious.

Goal of the invention of the present utility model is to provide a kind of employing land wheel imitated structure at above-mentioned the deficiencies in the prior art just, sets up the ridging height limiter, has the new-type wheat fertilizing tectorial seeder of fixed shape biofilm structure.Complete machine is at evenly seeding, ridging height, and tool is greatly improved on the performances such as even smooth shop film.

Goal of the invention of the present utility model can take following technical measures to be achieved: it comprises hitch 1, frame 2, fertilizer mechanism 3, fertilizer shaft 4, fertilizer can 5, speed distributing shaft 6, Seeding box 7, feed mechanism 8, seed level adjusting lever 9, the moving support 10 in back, suppression device 11, seed opener 12, banker 13, film pressing device 14, applicator boot 17, making ridge device 18, break shovel 20, seeding regulating handle 21, fertilizer regulating handle 22 and driving-chain 26, and adopts the prior art aggregate erection.It also has two copying devices 19 that make symmetrically simultaneously.It is made up of contour wheel 16, active gear wheel 27, support 28, passive gear wheel 29, profiling arm 24, regulating wheel 25, support plate 30; Contour wheel 16 is coaxial with active gear wheel 27, and is hinged by the front end of sliding bearing 32 with profiling arm 24, the upper end of support 28 and frame 2 welding, and lower end and profiling arm 24 are terminal hinged; One end of regulating wheel support plate 30 is welded on the profiling arm 24, and the other end is fixedlyed connected with regulating wheel 25 by bolt assembly.Passive gear wheel 29 is contained on the speed distributing shaft 16 by sliding bearing 31.Initiatively gear wheel 27, passive gear wheel 29 and regulating wheel 25 connect as one by driving-chain 26.Ridging height limiting plate 23 all fixedly is equipped with by bolt assembly in the next door of each banker 13 of being adorned on the moving support 10 in back.The biofilm frame 15 that film coiling roller is housed is overall fixed formula  shape, and between two profiling land wheels 16, fixedly is loaded on the frame 2.

The utility model advantage compared with prior art is conspicuous: the first, row's seed is even, has overcome the disconnected row phenomenon of being short of seedling.This is that the land wheel that drives seeding is hinged by profiling arm and frame owing to adopted profiling ground wheel construction, and by regulating wheel synchronous tension driving-chain, driving wheel fluctuates the seeding of continual driving seeding unit freely according to face of land height under own wt.The second, because the ridging height limiter has been installed, no matter speed of a motor vehicle height, ridging is consistent highly all the time, and little four-wheel can carry out seeding operation with the 3-4 shelves, has improved operating efficiency.Three, the whole  shape design of biofilm frame has strengthened integral rigidity, and is rational in infrastructure; Film coiling roller all can reach even smooth shop film in which kind of situation during making ridge, makes press mold height unanimity, has increased mulch film daylighting face, has given full play to the volume increase advantage of plastic mulching sowing.
