Abstract
The utility model discloses a chainless seeder which comprises a rack and a seeding unit; a land wheel mounted on a land wheel shaft is arranged on the rack, and is in transmission connection with theseeding unit through a transmission device; the seeding unit comprises a hole wheel which is arranged on the rack through a hole wheel shaft; and the same sides of the hole wheel shaft and the land wheel shaft are in transmission connection through a crank-connecting rod mechanism. The chainless seeder with simple structure, convenient maintenance, low fault rate and lower manufacturing cost overcomes the disadvantages of the prior chain transmission, avoids the phenomena of chain dropping, tightly clamping, miss seeding and the like in working, and improves the reliability of the work of seeder and work efficiency.
Description
Technical field
The utility model relates to the farm machinery technical field, especially a kind of sower.
Background technology
Present existing sower all includes land wheel and seeding unit, is connected by chain drive between land axle and the seeding unit axle, and land wheel drives the seeding unit axle by chain and rotates during work, thereby finishes the sowing process.The sower of this structure has following shortcoming: 1. chain falls chain easily in transmission process, thereby causes broadcast leakage, and refitting chain, after-culture bother very much.2. as utilize sower to interplant between crop row, straw, weeds etc. is wrapped on the sprocket wheel easily, produces the stuck chain phenomenon of falling, and the functional reliability of sower is greatly reduced.3. chain needs frequent lubricating maintenance, has increased maintenance workload.
The utility model content
The purpose of this utility model is to provide a kind of no chain sower without chain drive.
For achieving the above object, no chain sower of the present utility model comprises frame and seeding unit, frame is provided with the land wheel that is contained on the land axle, land wheel is in transmission connection by transmission device and seeding unit, seeding unit includes hole roller, hole roller is installed on the frame by the hole roller axle, and the homonymy of hole roller axle and land axle is in transmission connection by toggle.
Toggle comprises ground wheel crank, connecting rod and hole roller crank, and wheel crank one end in ground is fixedly connected on the land axle and an end of its other end and connecting rod is hinged; One end of the other end of connecting rod and hole roller crank is hinged, and the other end of hole roller crank is fixedly connected on the hole roller axle; The corresponding chute that is provided with the connecting rod stage casing slidely connects carriage on the frame in the chute, and connecting rod stage casing and described carriage are hinged.
Carriage is a back shaft.
Carriage comprises the slide block that is slidingly connected with chute and is fixedly connected on back shaft on the slide block that back shaft and connecting rod stage casing are hinged.
The utlity model has following advantage:
1. be in transmission connection by toggle between land axle and the seeding unit axle, avoided the defective of chain drive in the past, phenomenons such as chain, stuck and broadcast leakage can not appear falling in the work, simple in structure, easy to maintenance, fault rate is low, has improved the functional reliability and the operating efficiency of sower, and cost of manufacture is lower simultaneously.
Toggle specifically be provided with simple and conveniently, cost is lower.
3. when the end of two cranks forwards the line direction in hole roller axle center and land wheel axle center simultaneously to (dead-centre position) because the ground wheel crank is rotated further, at this moment connecting rod with back shaft as the fulcrum rotation and force the crank end on the hole roller axle to turn over the dead point.
4. carriage comprises the slide block that is slidingly connected with chute and is connected in back shaft on the slide block, and back shaft and connecting rod stage casing are hinged, and such setting can reduce the sliding friction loss of back shaft, has prolonged the service life of back shaft.

Fig. 2 is the plan structure schematic diagram of embodiment one running part;
Fig. 3 is the structural representation of embodiment two.
Embodiment
Embodiment one
As shown in Figure 1 and Figure 2, the no chain sower of present embodiment comprises frame 1 and seeding unit 3, frame 1 is provided with the land wheel 2 that is contained on the land axle 22, seeding unit 3 includes hole roller 7, hole roller 7 is installed on the frame 1 by hole roller axle 21, and hole roller axle 21 is in transmission connection by toggle with the homonymy of land axle 22.
Toggle comprises ground wheel crank 8, connecting rod 10 and hole roller crank 9, and wheel crank 8 one ends in ground are fixedly connected on the land axle 22 and an end of its other end and connecting rod 10 is hinged; One end of the other end of connecting rod 10 and hole roller crank 9 is hinged, and the other end of hole roller crank 9 is fixedly connected on the hole roller axle 21; The corresponding chute 6 that is provided with connecting rod 10 stage casings slidely connects carriage in the chute 6 on the frame 1, and carriage comprises the slide block 11 that is slidingly connected with chute 6 and be fixedly connected on back shaft 12 on the slide block 11 that back shaft 12 is hinged with the stage casing of connecting rod 10.The stage casing of described connecting rod 10 comprises the mid point and near the position thereof of connecting rod 10.
When no chain sower of the present utility model advanced, land wheel 2 drove hole roller 7 rotations by ground wheel crank 8, connecting rod 10, hole roller crank 9, thereby made seeding unit 3 work.When the end of two cranks 9,8 forwards the line direction in hole roller 7 axle center and land wheel 2 axle center simultaneously to (dead-centre position), because ground wheel crank 8 is rotated further, at this moment connecting rod 10 rotates back shaft 12 and forces hole roller crank 9 ends to turn over the dead point as fulcrum.
The utility model is simple in structure, and is easy to use, and various existing seeding units 3 and land wheel 2 all can adopt the connected mode in the utility model to connect into sower.Because ground wheel crank 8 is identical with the angular speed of hole roller crank 9, therefore can not exert an influence to seeding time and cave distance.As shown in Figure 1, because land wheel 2 turns to the switched in opposite with hole roller 7, rotating speed is identical, so can adapt to different cave distances by the hole roller 7 of changing different number types hole and the method for changing the land wheel 2 of different-diameter during bunch planting.
Embodiment two
As shown in Figure 3, the difference of present embodiment and embodiment one is: described carriage is the back shaft 12 that is slidingly connected in the chute 6, and back shaft 12 1 ends and connecting rod 10 stage casings are hinged.
Certainly, the utility model includes but not limited to present embodiment, as ground foreign material in concrete enforcement more for a long time, can add the case that cranks at ground wheel crank 8 and hang foreign material (certainly to prevent to touch, because 10 reciprocating motions of making short stroke of connecting rod in the utility model, and smooth outer surface, so foreign material can not brought influence motion in the crank cover into); And for example the pin joint of carriage and connecting rod 10 also can be positioned at connecting rod 10 middle parts part in addition; Above-mentioned conversion all drops within the protection domain of the present utility model.
