Abstract

The utility model relates to a sowing and fertilizing machine for the maize, which is composed of a seed box, a recess type sowing wheel, a fertilizer box, a fertilizing wheel whose surface is provided with a traverse groove, and a funnel type opening share which is provided with a fertilizer channel and a seed channel. The scraper of the sowing wheel is vertically arranged at the top part of the sowing wheel, and the phenomenon that the seed passes through the scraper forcibly to be broken is avoided. The side wall of the lower end of the seed channel of the opening share is provided with a gap, the upturned soil can enter into the channel from the gap, the fertilizer is covered over, but the seed is positioned at the upper side of the fertilizer and is separated from the fertilizer.

Description

Maize sowing, fertilizing machine

The utility model belongs to seeding machinery, is that revolving of linking of a kind of and rotovator broadcast formula corn seeding, fertilizer distributor.

Existing corn drill all is to revolve to broadcast the formula structure basically, it mainly by seeds box, stretch into pocketed in the seeds box and broadcast the seed wheel and be positioned at the funneling plough of broadcasting seed wheel below and form, wherein be provided with a scraper of seed sowing wheel in the seeds box exit.Each depression of broadcasting on the seed wheel can only hold a seed, and when it rotated, the depression on it was taken away seed, to not enter the seed retaining of depression in seeds box at the exit scraper plate, and the seed in the depression can pass through scraper plate, falls into plough then, enters in the soil again.But the scraper of seed sowing wheel of this class sower is positioned at the middle part of broadcasting the seed wheel, and the first half of promptly broadcasting the seed wheel extend in the seeds box, and scraper plate is for being horizontally disposed with.When the seed in the depression is crossed peak and is moved downward, because the influence of factors such as gravity, centrifugal force and vibration has the trend of overflowing from depression.On the other hand, owing to formed a funnelform space between the first half of broadcasting seed wheel and the seeds box rear box wall, seed and tank wall and broadcast seed and have frictional force between taking turns cause the seed at scraper plate place to be extruded very tightly in addition.Therefore, by scraper plate, seed can be squeezed broken by scraper plate seed herein first by by force; Second scraper plate distortion, promptly scraper plate increases with the gap of broadcasting between the seed wheel, makes a large amount of seeds outflows, causes out of control.In addition, existing corn drill fertile device of band application not.Because must guarantee that fertilizer and seed can not be mixed in the soil during fertilising.Promptly fertilizer should separate with seed in soil.So adopt the method for carrying out respectively of sowing at present mostly with fertilising.

The purpose of this utility model is to provide a kind of sowing, fertilising to carry out simultaneously at the problems of the prior art, and can guarantee that seed does not have fragmentation, accurate, the reliable a kind of corn seeding of sowing, fertilizer distributor.

The solution that realizes the utility model purpose is: the pocketed that the corn seeding that is provided, fertilizer distributor comprise seeds box, match with the seeds box outlet is broadcast the seed wheel and is positioned at the funneling plough of broadcasting seed wheel below, wherein is provided with a scraper of seed sowing wheel in the seeds box exit.Improvements of the present utility model are: scraper of seed sowing wheel vertically is located at the top of broadcasting the seed wheel, is provided with the fertilising wheel that fertilizer can and surface have translot respectively side by side on seeds box and the next door of broadcasting the seed wheel; Funneling plough is provided with two mutually isolates, and respectively with the fertilising wheel with broadcast seed and take turns corresponding passage, wherein has a gap on the lateral wall of seed passage lower end.

Scraper of seed sowing wheel is positioned at the top of broadcasting the seed wheel, and this has just been avoided the accumulation extruding of seed at the scraper plate place, has also avoided seed to skid off the possibility of depression.

Gap on the plough seed passage makes back the soil that turns over can enter gap, and promptly the soil of seed passage will be higher than the soil of fertilizer passage, and consequently after planting fertilizer is down, and seed is last, and separates fully.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the utility model distribution map of seed and fertilizer after planting.

As shown in Figure 1: seeds box 1 also is in the same place with fertilizer can 2, and is middle by dividing plate 3 isolation.Fertilising wheel 4 and seeding wheel 5 are actually left and right sides two parts of a monolithic wheel, and its axle 6 connects with profile of tooth road wheel 7.There are six translots 8 on the surface of fertilising wheel 4, is used to carry fertilizer.There are six depressions 9 on the surface of broadcasting seed wheel 5, is used to carry the corn seed.This machine is bound up with rotovator, and when it advanced with rotovator, road wheel 7 drove fertilising wheel 4 and broadcasts 5 rotations of seed wheel.Since fertilising wheel 4 and the upper face of broadcasting seed wheel 5 respectively with the outlet tight connecting of fertilizer can 2 and seeds box 1, so have only the fertilizer in the fertilising wheel translot 8 to be taken out of; In like manner, the seed of only broadcasting in the seed wheel depression 9 can be taken out of.Fertilizer of being taken out of and seed fall into the fertilizer passage 11 and the kind subchannel 12 of the funneling plough 10 of its below respectively, in the soil 13 of going forward side by side.

As previously mentioned, scraper of seed sowing wheel 14 of the present utility model is positioned at the top of broadcasting seed wheel 5, its concrete structure as shown in Figure 2: scraper plate 14 is a rubber flap, and it is fixed on the gripper shoe 15, and then be fixed on the rear wall of seeds box 1, guard shield 16 is in order to prevent that seed 21 from flying out outside the machine.Because the space of scraper plate 14 fronts is very big, seed is also little to its horizontal applied force, thus rubber flap 14 all the time can with broadcast the seed wheel and fit tightly, and seed also can not be squeezed broken.In addition, on the lower end sidewall of plough seed passage 12, opened a gap 17.During the plough trench digging, returning a part of soil that turns over can enter in the seed passage 12 from gap 17, fertilizer is covered, thus the effect that causes fertilizer to separate with seed.It distributes as shown in Figure 3: bottom 18 is a fertilizer, and intermediate layer 19 is a soil, and upper strata 20 is the soil that covers seed 21.

The utility model has the advantage of: the phenomenon of broken seed out of control and crowded accurately can not take place in sowing. In addition, can realize that fertilising and sowing once finish, not only save independent fertilising operation, save fertilizer, and since fertilizer below seed, and both separate, so guaranteed effective utilization of fertilizer.
