Description

Hill-drop planter

The utility model relates to a kind of sower, but the device of particularly a kind of cavitation sowing.

The shortcoming that existing hill-drop planter often has has: when the sower rotating speed was fast, sowing did not just become bunch planting, and becomes the drilling of sowing continuously; General hill-drop planter, its pitch-row of sowing fixes, and can not adjust with need; The amount of broadcasting of seed can not be adjusted; The lower seed disk of sower, the pipe of sowing stopped up easily after seed made moist.Because the existence of the problems referred to above makes the peasant lose the confidence to the effect of sower.Because the soil property difference of various places, doing when wetting of weather changes, and sows less so sower should be able to adapt in good soil, has more seedling; In poor soil, sow, to guarantee to have more seedling more; When during climatic variation or hole required distance changed, the relevant parts of sower should be able to award suitable adjustment.Existing " planter " patented technology also has spacing in the rows not adjust, and the cavitation degree of seeding is poor, and seeding quantity can not be adjusted, and operating efficiency is not high, a shortcoming such as efficient a little more than the manual dibbling.

The purpose of this utility model is exactly will provide a kind of to do lower seed hole distance, seeding quantity adjustment and prevent that seed from being squeezed the hill-drop planter of broken device.

The utility model is to implement like this:

The sower that the utility model relates to is on the crossbeam that hangs over behind the hauling machine, can hang two square shafts on the crossbeam, and 3 of seeders are set on the every square shaft, if will hang 1-2, need add universal joint, otherwise concentricity is poor more, can damage machinery.

Each seeder is to be made of land wheel, gear, chain, square shaft, moving tooth wheel, elastic claw bar, connecting rod, seeding board.A land wheel is connected with square shaft by gear, chain, and land wheel is drawn the back and rolls on the field, drives the square shaft rotation, drives the hole seeding arrangement running.By the change of gear size, chain length, just can reach the purpose that changes the spacing in the rows of sowing.

Hole seeding arrangement is a moving tooth wheel that is contained on the square shaft, sets up four moving tooth bars separately by 90 ° of angles on the circumferential edge of moving tooth wheel.When the rotation of moving tooth wheel, what can collide in succession with four moving tooth bars is an elastic claw bar that curves 90 ° ± 5 ° of angles, the one-tenth angular position of elastic claw bar is provided with fulcrum, this fulcrum is fixed on the upright beam, upright beam is fixed on the crossbeam of device, the springing position of elastic claw bar is strained by an extension spring, and the other end of extension spring is fixed on Li Liangshang.Open a circular hole mutually nearby at the fixing point of this extension spring and upright beam, can insert an inserted link in the circular hole, the function of inserted link is when hauling machine is operated on the limit, field, when the control area of the dibbler that is drawn will be above the area on limit, field, to have several phenomenons that repeat sowing can take place capablely at the ground on limit, field upper seeding wheel.Therefore the elastic claw bar can be moved apart the moving tooth wheel with hand, the elastic claw bar can spur connecting rod and extend the position that surmounts upright beam at this moment, insert in the circular hole of vertical rod with an inserted link, then inserted link can play the effect that stops the moving tooth bar on elastic claw bar and the moving tooth wheel to be collided, and this dibbler is quit work again.So the dibbler of hauling machine traction can be as required, only bunch planting is carried out in unseeded field still, resowing phenomenon can not take place just.The other end and the connecting rod of elastic claw bar join, and connecting rod and seeding board join.So the moving quarter turn of moving tooth wheel revolution, the moving tooth bar can be stirred the elastic claw bar once, and then the elastic claw bar can spur seeding board once by connecting rod, and to be subjected to the pulling force of spring be the moment return-to-home position to the elastic claw bar thereafter.On seeding board is provided in a side of at the bottom of the awl of seed hopper, connect by connecting rod one can twitch advance kind of plate and a screw rod control panel of being regulated by screw rod is formed, seeding board slides before and after can be in the track plate, and the screw rod control panel can be controlled it separately with screw rod and moves forward and backward; Whenever stir once when the elastic claw bar, just affect connecting rod once, then also make seeding board pulling once, promptly be subjected to the effect of the extension spring original place of rebounding moment again after pulling, be one and advance kind and sow process.The empty chamber of advancing between kind of plate and the screw rod adjustment plate is a seed chamber, and the adjustable size joint screw rod of seed chamber is adjusted the screw rod of plate, makes this plate reach or retreats the Volume Changes of finishing seed chamber.Storage kind bucket on screw rod is adjusted plate exports a side, and anti-millstone is housed; And a base plate that circular lower seed hole is arranged is arranged below seeding board, base plate and track plate are fixed together.When seeding board spurs once, being about to seed chamber pulls to storage kind of a bucket exit and makes seed enter seed chamber, extension spring on this moment elastic claw bar is with the elastic claw bar original place of rebounding, this makes seed chamber relative with the circular hole of sowing in a flash, seed promptly falls in seed chamber, and this pugil seed forms a cave seed among promptly entering the field.Instantly promptly begin next period run after intact kind, promptly the moving tooth bar is stirred the elastic claw bar, the pulling connecting rod, make the seed chamber of kind of plate into aim at storage kind of bucket outlet, seed is filled seed chamber again, and the elastic claw bar is subjected to the effect of extension spring that seeding board moment is rebounded, seed chamber is alignd, i.e. sowing again with lower seed hole.In the running, seed can be clipped between storage kind of bucket end opening and the seeding board.Broken for preventing that seed from being squeezed, it is broken then can to prevent that seed from being squeezed by anti-millstone.Anti-millstone is one and is contained in storage kind of bucket bottom, adjust the platen that one of plate one side has only two running rollers near screw rod, establish a push rod on the platen, cover one spring on the push rod, the case top that is stuck on the push rod is passed at the top of push rod, and case only has opening in the Lower Half of running roller, and remainder seals entirely, platen only can move up and down in case, but seed advances less than platen top.When seed sticked into below the running roller of platen, the spring of running roller was compressed, and moves on the platen, pushes away on the push rod.At this moment be pressed in the pressure that the seed under the running roller is subjected to and offset by spring, and can not be squeezed broken, thereby reach breakage-proof function.

By the hill-drop planter of above-mentioned design, as seen the spacing in the rows of its bunch planting is adjustable, and the amount of sowing is adjustable, and this need descend the different problems of measuring seeds with regard to having solved the different soils quality; When the speed of service quickening of hauling machine, can not influence the function of its cavitation sowing, because design considering that sowing is to make the elastic claw bar periodically spur seeding board by moving tooth wheel Periodic Rotating to reach the bunch planting purpose, the fast again sowing that also gets one cave, a cave of speed yet; Seed makes moist for another example, can the size of seed chamber be made adjustment by adjusting screw rod, and open greatly in the space of seed chamber, then just impossible blockage phenomenon; Very narrow when the sowing field, can pass through the fixedly method of elastic claw bar, a part of seeder was lost efficacy, be implemented in the function of the narrow ground bunch planting on limit, field, and resowing phenomenon can not take place; Hill-drop planter is provided with anti-millstone, can prevent the phenomenon of squeezing broken seed at seeding time; Thereby formed the more complete hill-drop planter of performance of the utility model indication.
