Abstract

The utility model relates to a seeding machine. The utility model comprises a machine frame, a driving wheel, a seeding device, a seed box, a seed conveying pipe and a furrow opener. The utility model is characterized in that the furrow opener is fixed on a row spacing adjusting crossbeam with bolts by the supporting frame of the furrow opener, a compressed spring of the furrow opener is arranged between the supporting frame of the furrow opener and the machine frame, the utility model adopts a dual-hole traction, and the lever type elevating mechanism of the machine frame, a steering tailwheel and a working unit are arranged on the utility model. The utility model has the advantages of adjustable row spacing, uniform seeding depth, application to various seeds and various earthiness, flexible and convenient operation and light weight, and the utility model can be used for fertilizing.

Description

A kind of new type sowing machine

The utility model relates to the pull-alongs sower, more particularly, be a kind ofly include frame, be arranged on chaindriven seeding unit between drive on the frame and the drive, at the seed-box above the seeding unit, be connected the grain tube between seed-box and the plough and be positioned at the sower of each parts of plough of grain tube lower end.

There is following weak point in pull-alongs sower of the prior art:

1, because plough is fixed by welding on the crossbeam, and the distance between its adjacent plough is non-adjustable, therefore sows classification and be restricted.

2, owing to be non-resilient the connection between plough and the frame, this not only causes seed level inconsistent, and when plough runs into obstacle, or is blocked and can not moves ahead or damage plough.

3, elevating mechanism complex structure, operation inconvenience, effort.

4, because the traction of the single hole on the power traction plate to making complete machine have bigger swing in motion, therefore is difficult to guarantee the straight line sowing.

5, turn to difficulty, use inconvenience.

6, no working position, the operator is random walk in operating process, and labour intensity is big.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, a kind of novel pull-alongs sower is provided, this machinery has that line-spacing is adjustable, seed level is consistent, travel in little, the easy to operate performance of swing, steering mechanism and workbench position are set simultaneously, to alleviate labor intensity of operating staff.

The purpose of this utility model is achieved through the following technical solutions:

The utility model comprises frame, be arranged on chaindriven seeding unit between drive on the frame and the drive, at the seed-box above the seeding unit, be connected the grain tube between seed-box and the plough and be positioned at the plough of grain tube lower end, it is characterized in that:

A, line-spacing be set regulate crossbeam, plough by opener post by being bolted on the crossbeam;

B, the frame elevating mechanism is set, described frame elevating mechanism is made of lever elevating lever and securing rod;

C, the plough stage clip is set between opener post and frame;

D, on the power traction plate, offer two towing pads;

E, turn to tail wheel, and the afterbody frame is provided with working position in the setting of frame afterbody.

With there to be technology to compare, the utility model is rational in infrastructure, simple, has alleviated facility weight greatly, its power can be 6,8,10 and 12 s' tractor, also can be used for fertilising.

Fig. 1 is the utility model structural representation.

Fig. 2 regulates the beam structure schematic diagram for the utility model line-spacing.

Fig. 3 is the utility model power dagger plank structural representation.

By the following examples, in conjunction with the accompanying drawings, the utility model is further described.

Embodiment:

Referring to Fig. 1 and Fig. 2, there is a groove 16 at the middle part of line-spacing adjusting crossbeam 1 in the present embodiment, opener post 8 constitutes by two sections of front and back are hinged, the leading portion support is entrapped in the crossbeam groove, can in groove, horizontally slip, and be fixed, change the distance between the adjacent opener post by bolt, can change the sowing line-spacing of this machine, to adapt to different classes of seed.

Referring to Fig. 1 and Fig. 3, present embodiment is offered two towing pads 15 on power traction plate 4, and power section connects firmly by two towing pads and frame.The setting of two towing pads can reduce the swing of frame in travelling significantly.

As shown in Figure 1, plough stage clip 11 is set between opener post 8 and frame.The obstacle because the existence of stage clip 11, plough 5 can successfully be jumped over is unlikely to be blocked or to damage plough.Also, make seed level even, and can be applicable to different soil properties owing to the existence of stage clip.

Again as shown in Figure 1, constitute the frame elevating mechanism by lever elevating lever 10 and securing rod 9, elevating lever 10 rod ends are hinged on the central authorities of crossbeam 1.Corresponding to securing rod 9 rod end positions, a lock hole 17 is arranged on crossbeam 1.Because the setting of lever makes the frame lifting light, flexible.The setting of securing rod 9 makes complete machine can not have when stopping to be lifted.At the frame afterbody, be provided with simultaneously can greatly conveniently turn to turn to tail wheel 13, and on the afterbody frame, be provided with working position 12, the operator can be sitting on the working position and operate, and reduces labour intensity greatly.

Identical with prior art is the top that seed-box 6 is positioned at seeding unit 5, is connected grain tube 7 between seed-box 6 and the plough 14, carries out transmission by driving chain 3 between seeding unit 5 and the drive 2.

Claims

1, a kind of new type sowing machine, comprise frame, be arranged on drive (2) on the frame, and drive (2) between chaindriven seeding unit (5), be positioned at seeding unit (5) top seed-box (6), be connected the grain tube (7) between seed-box (6) and the plough (14) and be positioned at the plough (14) of grain tube (7) lower end, it is characterized in that:

A, line-spacing be set regulate crossbeam (1), plough (14) by opener post (8) by being bolted on the crossbeam (1);

B, the frame elevating mechanism is set, described frame elevating mechanism is made of lever elevating lever (10) and securing rod (9);
