Description

A kind of novel hill-drop planter

Technical field

The invention belongs to agricultural machinery technological field, it is simple to be specifically related to a kind of structure, can realize small-sized seed bunch planting, and bunch planting amount, novel hill-drop planter that bunch planting spacing in the rows is adjustable.

Background technology

Hill-drop planter generally can be divided into perforating type hill-drop planter and furrowing type hill-drop planter.Perforating type bunch planting mainly utilizes device of charging seed to wait that sowing sub indenting tool of putting into is charging seed in a hole of place formation, and its bunch planting spacing in the rows is non-adjustable.Furrowing type hill-drop planter mainly utilizes plough to output kind of a ditch, and then seed fixed point drops in ditch by seeding unit, last suppression of soil.Existing perforating type hill-drop planter and its seeding unit of furrowing type hill-drop planter mostly are disc type, complex structure, and manufacture difficulty, bunch planting amount is non-adjustable, and when high-speed job, cavitation is not obvious, easily occurs sowing problem continuously.

Summary of the invention

The object of the present invention is to provide that a kind of structure is simple, cavitation is obvious, and bunch planting spacing in the rows and all adjustable novel hill-drop planter of bunch planting amount.

Technical solution of the present invention is: invent a kind of novel hill-drop planter, in the bottom of common external feed, to connect a dibbler, bunch planting function is realized by the seal chamber opening and closing dibbler, adjustment simultaneously by regulating outer groove-wheel effective operation width to realize bunch planting amount, realizes the adjustment of bunch planting spacing in the rows by changing drive sprocket.

Described novel hill-drop planter, comprises suppression drive part, seeding part, bunch planting part and frame.It is characterized in that:

Described suppression drive part is arranged on frame rear end, comprise: land wheel, ground wheel sprocket, cam, ground wheeling rack, land wheel regulating spring, duplex chain wheel and cam, wherein land wheel regulating spring is arranged in the middle part of ground wheeling rack and between frame rear end, ground wheeling rack upper end and frame hinged, land wheel is installed in lower end, land wheel can swing around ground wheeling rack upper link point, ground wheeling rack upper end thereof axle installs duplex chain wheel and cam, ground wheel sprocket is arranged on land wheel, with land wheel concentric, rotate with land wheel, land wheel chain wheel drive duplex chain wheel and cam, duplex chain wheel drives the seeding sprocket wheel of seeding part.

Described seeding part is arranged on upper surface, frame front end, comprise: plant case, external feed, seeding sprocket wheel, discharging tube, wherein plant case bottom end face and external feed is installed, external feed and seeding sprocket wheel are arranged on seeding unit axle, seeding sprocket wheel is driven by duplex chain wheel, discharging tube is installed in external feed lower surface, and discharging tube lower end is inserted in the sleeve of bunch planting part.

Described bunch planting part is arranged on below frame front end, comprise: lever, stage clip, depression bar, grain conductor, sleeve, conical plug, plough, wherein, its intermediate part is hinged on central rack, the cam surface of one end and drive part, one end contacts with depression bar upper surface, depression bar upper end is big column, lower end is small column, on small column, cover has stage clip, there is screw thread bottom, conical plug is installed, the conical plug conical surface coordinates with sleeve bottom inner conical surface, it is inner that sleeve is arranged on grain conductor upper end, with screw fastening, grain conductor is arranged on the lower end of kind of case, plough is arranged on before grain conductor, it is inner that plough is inserted in grain conductor bottom.

Specific works process of the present invention is as follows: unit is by tractor-drawn, land wheel rotarily drives ground wheel sprocket synchronous rotary, drive duplex chain wheel and cam, duplex chain wheel drives external feed to start seeding simultaneously, now cam is in extreme lower position, under the effect of stage clip, conical plug is in closed condition, the external feed seed of discharging is fallen in the seal chamber constructed by the sleeve of grain conductor inside and conical plug along discharging tube and is saved bit by bit, along with the rotation of seeding sprocket wheel, external feed stops seeding, the cam turning radius increases until reach maximum simultaneously, conical plug is opened, the seed of seal chamber drops in the groove that plough leaves, realize sowing, then cam radius of turn reduces to minimum of a value fast, under the effect of stage clip, conical plug is closed again, iterative cycles like this, thus realize bunch planting.Before bunch planting, bunch planting spacing in the rows can being changed by changing duplex chain wheel, bunch planting amount can be changed by regulating external feed working width.

It is simple that the present invention has structure, and cost of manufacture is low, is applied in small-sized seed bunch planting operation, and cavitation is obvious, and bunch planting spacing in the rows, bunch planting amount are all adjustable.

Accompanying drawing explanation

Structural representation when Fig. 1 is conical plug closedown.

Fig. 2 is conical plug structural representation when opening.

Fig. 3 is front view and the vertical view of sleeve.

As shown in FIG.: 1 land wheel; 2 ground wheel sprocket; 3 ground wheeling racks; 4 chains 1; 5 land wheel regulating springs; 6 duplex chain wheels; 7 cams; 8 frames; 9 levers; 10 chains 2; 11 kinds of casees; 12 seeding sprocket wheels; 13 external feeds; 14 discharging tubes; 15 stage clips; 16 depression bars; 17 sleeves; 18 screws; 19 grain conductors; 20 conical plugs; 21 ploughs.

Embodiment:

As shown in Fig. 1 ~ 3: land wheel 1 is at the rear lower of whole facility, be arranged on ground wheeling rack 3 lower end, ground wheeling rack 3 upper end thereof is in frame 8 rear end, land wheel regulating spring 5 is installed at middle part, under the effect of land wheel regulating spring 5, land wheel 1 can float around the upper link point of ground wheeling rack 3, but all the time with earth surface, ground wheel sprocket 2 on land wheel 1 is with land wheel 1 rotary actuation duplex chain wheel 6 and cam 7, duplex chain wheel 6 drives seeding sprocket wheel 12, cam 7 and lever 9 one end contact, be hinged in frame 8 in the middle of lever 9, the other end contacts with depression bar 16 upper surface, on the small column of depression bar 16, cover has stage clip 15, depression bar 16 small cylindrical surface bottom has screw thread to install conical plug 20, tap web plug 20 male cone (strobilus masculinus) coordinates with sleeve 17 lower end inner conical surface, it is inner that sleeve 17 is arranged on grain conductor 19 upper end, fastening with screw 18, grain conductor 19 is fixed on below frame 8 front end, plough 21 is fixed in the frame 8 before grain conductor 19, pipe 19 bottom is caused to be inserted into plough 21 inner.

When work of the present invention starts, ground wheel sprocket 2 on land wheel 1 drives duplex chain wheel 6 and cam 7, duplex chain wheel 6 drives seeding sprocket wheel 12 to start seeding, the now minimum radius of turn of cam 7 and lever 9 end thereof contacts, under the effect of stage clip 15, upwards, conical plug 20 is in closed condition to depression bar 16, the seed that seeding part is discharged drops in the enclosed cavity that conical plug 20 and sleeve 17 formed, and saves bit by bit; Next, cam 7 rotates, and radius of turn increases gradually, lever 9 one end contacts upwards with cam 7, and the downward moulded rod 16 of the other end, when rotating to maximum radius place, conical plug 20 separates with sleeve 17 inner conical surface, and cavity is opened, and seed drops in the kind ditch that plough 21 outputs in grain conductor 19; Then cam 7 radius of turn suddenly reduces, and upwards, conical plug 20 male cone (strobilus masculinus) is combined with sleeve 17 inner conical surface depression bar 16, and cavity is closed, and saves bit by bit seed.So repeatedly, realize bunch planting, bunch planting spacing in the rows can realize by changing duplex chain wheel 12, and bunch planting amount can realize by regulating the effective work width of external feed 13.
