The utility model is especially suitable for the miniature tilling and seeding work of maize and legume crop.

Description

Miniature combined machine for tilling and seeding

The utility model relates to a kind of small-sized agriculture combined machine, is the small-sized agriculture combined machine of a kind of whole ground parts and the combination of sowing parts specifically.

Existing miniature seeding machine is generally manpower or animal power drives, and rigidity of frame is poor, the effort of taking a lot of work, and seeding quality is poor.Small-sized scarification equipment, rigidity of frame is strong, is dragged by small tractor, acts on but can only finish wholely.

The purpose of this utility model be drag combination tilling and seeding machine tool for a kind of minicomputer that can finish whole ground and sowing simultaneously.

Task of the present utility model is that this reality is existing: small-sized maneuver plough and sowing parts are combined as a combined machine, described maneuver plough is a double-bladed plough, one cover sowing parts are set on frame, comprise seed-box, seeding unit, seeding unit drives controlling organization, the funnel of sowing, the flexible pipe of sowing, trench digging head and trench digging head support, on the frame before and after seed-box and seeding unit are fixedly installed between the plough leg, seed shaft in the seeding unit is an one-sided extension shaft, this axially outer end is provided with sprocket wheel, and it is the rough lock transmission that the plough of double-bladed plough wheel is gone up between the sprocket wheel that is provided with, be connected with frame with two bearings in the middle of this extension shaft, between extension shaft and bearing axial sliding fit is arranged, also be provided with the axially movable driving lever of a control extension shaft on this extension shaft, the trench digging head support is a rigid support, joins through the plough leg of U type clamping tool and preceding plough.

Have uniform seed distributing groove on the seed wheel excircle, can also adopt the nest ocular structure.

Plow frame hangs over the small tractor back during use, and the back of plow frame is dragged a dish rake again, and a people upright rake of a people of driving is finished stubble-cleaning simultaneously, ploughs and sows several functions.Seed wheel is through plough wheel deceleration, and seed is by the race sustained release, and the position of control driving lever can change the effective active length of seeding wheel race in the chamber of sowing, to select the amount of sowing; After the height of plough wheel is determined, also can upper and lower mobile trench digging head support, regulate a trench digging position, determine the best trench digging degree of depth of sowing on demand.Only need plough when not needing to sow, move on the bearing support of will ditching that the back is fixing to get final product.

The utility model can be finished stubble-cleaning, arable land and program request operation simultaneously through field trial, and the spacing in the rows of sowing, line-spacing and the degree of depth are even, and the amount of sowing control is respond well, and saving of work and time reaches designing requirement.Spacing in the rows is between 4-5cm, and line-spacing is between 40-44cm, and the amount of sowing is 2-2.5kg for every mu, and particularly suitable corn and legume crop cultivated broadcast integration of operation.

Below in conjunction with drawings and Examples the utility model is specified:

Fig. 1 is the utility model main structure schematic diagram.

Fig. 2 is a trench digging bearing support johning knot composition.

Fig. 3 is a seed shaft mechanism structure schematic diagram.

Fig. 4 is a seed wheel plectrum end view.

Fig. 5 is the seed wheel radial cross-section.

Referring to Fig. 1 and Fig. 2.Seed-box (1) is arranged on preceding plough (5) and the back frame (2) of ploughing between (4), between sprocket wheel on the seed wheel (3) and plough wheel (6) is the rough lock transmission, plough was ploughed on the leg (10) before a trench digging bearing support (7) one ends were fixed on U type anchor clamps (11), the other end is fixedly connected with trench digging head (8), and trench digging head (8) is connected with the flexible pipe of sowing (9).

The seed shaft mechanism structure is seen accompanying drawing 3-5, is provided with between the end opening of seeds discharging box (13) and seed-box (1) to open and close valve plate (12), and seeds discharging box (13) lower end is funnel of sowing (14) and the flexible pipe of sowing (9).Seed wheel (20) and the coaxial installation of plectrum (19) are arranged in the seeds discharging box (13).Seed wheel extension shaft (15) is connected with frame (2) through two bearings (16), (17), can endwisely slip between axle (15) and bearing (16), (17), driving lever (18) is a lever, the centre is connected with frame (2), one end is connected with extension shaft (15), with the axial location of control seed wheel (20).Sprocket wheel (3) is located at the outer end of extension shaft (15).

Two restraint projectioies (21) are arranged on the plectrum (19), be installed in the side chamber of seeds discharging box (13), place restrictions on the rotation of plectrum (19).

Have uniform seed distributing groove (22) on seed wheel (20) excircle.The rotating speed of the circumference distance of groove (22) and seed wheel (20) is controlled the spacing in the rows of sowing, effective length control the sow amount of groove (22) in the chamber of sowing.

Claims (2)
