Description
Technical field
The invention belongs to agricultural mechanical field, is a kind of copying device in the agricultural seeding machine concretely, is applicable to the copying device of single body seeder, also is specially adapted to multiplerow seeder.
Background technology
At present, sower particularly precision point sowing technology is widely used in agricultural seeder, and described sower is combined into one by devices such as the trench digging of installing on the frame, fertilising, earthing, sowing, feeler mechanisms usually.Various seeding machinaries connect with the hanging device of tractor in use, realize rising and falling of single unit system.Like the main fine strain of millet carrier base of sower and drive wheel bracket for being rigidly connected, during sowing because exist big and small lump of earth in the field, ground is rough and uneven in surface; Cause land wheel unsettled, stall causes being loaded on the also stall of sprocket wheel on the land wheel live axle; And this sprocket wheel rotates through the fertilizer kind axle that chain drives fertile case, and the feed shaft that also drives in kind of the case that has rotates, so the driving wheel stall causes also stall of feed shaft; Make fertilizer or sowing be interrupted, have a strong impact on seeding quality.For this reason, prior art is to be connected with main draw beam through two link rod supports respectively in the both sides of each frame, keeps substantially parallel thereby the formation four-bar linkage includes the copying device of spring to solve facility and ground, guarantees the land wheel kiss the earth.But, make the fertile case volume that is positioned at the frame top be restricted because existing copying device is mounted in the frame both sides.Development along with large farm machinery; Agriculture requirement is sowed 4 row, 6 row, 8 row etc. simultaneously; Need be installed in each single body seeder side by side on the main draw beam of tractor, therefore, existing copying device makes not only that fertile case volume is less and makes the user in use must frequently add fertilizer; Thereby reduced the production efficiency of multirow operation, and interfered with each other easily between the copying device of each independent sower of installing.In addition, the parts that existing copying device is installed are more, install loaded down with trivial details.
Summary of the invention
The objective of the invention is to solve the weak point of above-mentioned prior art, propose a kind of simple in structure, applicable to the frame copying device on the multirow precision sower.
The objective of the invention is to realize like this:
The hitch of apparatus of the present invention for connecting between traction housiung separator and the sower; It is characterized in that; But hitch comprises rotating shaft 20 devices and teeter link rod of the land wheel upper and lower displacement that can make the sower both sides at least; And the structure member formation that connects with traction housiung separator and sower, but the teeter link rod includes at least one joint, and an end is used for connecting with the traction housiung separator; Rotating shaft 20 is fixed on the rotary shaft rack 23 of hitch body bottom through hinged block 19; Hinged block 19 is provided with and is used to connect the rotating shaft coupling bar 18 that draws housiung separator; Rotating shaft coupling bar 18 is used for connecting with the traction housiung separator; But the link rod of teeter is arranged on the upper end of hitch, and forms angle with rotating shaft coupling bar 18; But the link rod of described teeter is divided into three sections at least, and promptly first link rod 12, second link rod 11, the 3rd link rod 10, the first link rods 12 connect with second link rod, 11 bearing pins, and second link rod 11 connects with the 3rd link rod 10 bearing pins, forms to comprise two joints at least; But the link rod of described teeter is divided into two sections at least, and promptly first link rod 12, second link rod, 11, the first link rods 12 connect with second link rod, 11 bearing pins, forms to comprise a joint 17 at least, and described first link rod 12 is or/and second link rod 11 is a ball rod; But the link rod of described teeter is arranged on hitch body upper end, and to form angle with the center line of rotating shaft coupling bar 18 be 20-85 °, further is optimized for 35-55 °; The rotary shaft rack 23 of described hitch body bottom is a spill, and the middle part is hinged block 19 fixedly, and both sides are provided with the 3rd and draw ear 24, make it possible to sower frame 6 on the 4th draw ear 25 to connect; The described structure member that connects with traction housiung separator and sower; Comprise two frames suspension link rods 8,8.1 of drawing downwards from the upper end of hitch body as leg-of-mutton two hypotenuses and rotary shaft rack 23 as base longitudinal carrier triangular in shape; One end of frame suspension link rod 8,8.1 is fixed on the both sides the 4th of sower frame 6 and draws on the ear 25, and the other end connects with the 3rd link rod (10) through link rod regulating sleeve 28; The described structure member that connects with traction housiung separator and sower also comprises and hangs oblique link rod 7,7.1 to the frame of sower frame 6 both sides extension; Back first of one end and frame 6 drawn on the ear 4; The other end and axle sleeve 26 are connected in the upper end of frame suspension link rod 8,8.1, make when the traction housiung separator promotes sower more stable.
Technology of the present invention has following advantage: the present invention be similar to pendulum model frame imitated structure can with the supporting use of any traditional precision sower; This apparatus structure compact, take up room little; Make fertile case volume obtain maximization, reduced the input of manpower, apparatus of the present invention are seeding operation separately both; Also can be connected in series back a plurality of monomers operation simultaneously and promptly use, enhance productivity greatly as mainframe.
