Description
Technical field
The invention belongs to agricultural mechanical field, particularly relate to a kind of wheat sowing machine.
Background technology
Wheat is one of important cereal crops of China, the especially first cereal crops of North China each province.In ad initio wheat cultivation theoretical frame so far, wheat cultivation all must, after having carried out soil ploughing, having harrowed the soil cultivation programs such as a kind of farm tools, carry out ditching, putting the sowing programs such as seed, blinding, suppression.Its agronomic technique feature is: 1, elder generation is whole then sows well; 2, seed will directly be sown into plough horizon certain depth; 3, branch's sowing, has certain distance between row and row, and seed is expert at interior concentrated crowded.Its main seeding method has: wait the narrow drilling of line-spacing, wide drilling, wide-and narrow-row drilling, alveole dense planting, although these seeding methods have some advantages, such as relatively facilitates in management, still have a lot of defect compared with broadcasting sowing.The plantation of row ridge has quite a lot of place to be all contrary with wheat own biological characteristic, do not meet Growth of Wheat characteristic exactly, the wheat of row ridge plantation, concentrates the inside of being expert at, plant strain growth limited space, to strive unavoidably to eat to strive and drink, particularly in the wheat tillering key period, performance more obvious, between ridge, vacant lot is not utilized effectively, and cause large quantity of moisture to evaporate, be unfavorable for soil moisture conservation.Although the current wheat seeder of China is still based on traditional drilling machine, but to promote the impetus powerful for wheat sowing machine tool, although existing wheat associating seed broadcaster can meet rotary tillage, fertilising, broadcasts sowing, the disposable operation in suppression of soil, but still deposit more a little denounce, such as sowing depth is inconsistent, broadcasts sowing uneven, rotary tillage wound kind, sowing earthing is insufficient and follow-up intertillage management is inconvenient, can not adapt to the line space requirement that wheat cultivation is.
Summary of the invention
The object of this invention is to provide a kind of can effectively raising and broadcast sowing the uniformity and the wheat sowing machine sowing efficiency.
For achieving the above object, the technical solution used in the present invention is:
A kind of wheat sowing machine, comprise frame, frame front end is provided with hitch, and frame is provided with from front to back successively rotary cultivator attachment, dials native device, fertilizing and seeding apparatus, suppression device, described rotary cultivator attachment is the rotovator being installed on frame leading portion; Described group of native device is the soil moving wheel being installed on rotovator rear; Described fertilizing and seeding apparatus comprise fertile case and its underpart being installed on frame stage casing fertilizing mechanism, plant case and its underpart broadcast sowing mechanism; Described suppression device comprises the suppression wheel shaft and press wheel that are installed on frame back segment.
Described soil moving wheel comprises wheel shaft, and wheel shaft is provided with cylinder soil moving wheel body, soil moving wheel body is provided with blade; Described mechanism of broadcasting sowing comprises the discharging tube on top and the flow distribution plate of bottom, and flow distribution plate cross section is L-shaped, and face is evenly equipped with multiple projection to L shape flow distribution plate hypomere plate.
Described L shape flow distribution plate hypomere both sides are provided with flanging upwards.
The power of described rotary cultivator attachment is provided by the draw-gear of seed broadcaster, and group native device and rotary cultivator attachment pass through belt transmission; Fertilizing mechanism, broadcast sowing mechanism by chain with suppression device be in transmission connection.
The invention has the beneficial effects as follows:
1. structure of the present invention is simple, and manufacturing process is simple and cost is low.Broadcast sowing the effective of the even seed of mechanism, especially when broadcasting sowing district and being larger, seed even results can obtain effective guarantee.Broadcast sowing mechanism and comprise the discharging tube on top and the flow distribution plate of bottom, flow distribution plate cross section is L-shaped, and face is evenly equipped with multiple projection to L shape flow distribution plate hypomere plate, arranges projection and is used for even seed, ensure that wheat broadcasts sowing uniformity.
2. when utilizing rotovator to get rid of soil to complete earthing for the wheat sowing machine promoted the use of at present, seed soil overlay capacity is inadequate, and the present invention selects between rotovator and seed-fertilizer box, to install soil moving wheel to ensure the soil overlay capacity of seed.

Fig. 2 dials native apparatus structure schematic diagram in the present invention;
Fig. 3 broadcasts sowing mechanism's structural representation in the present invention.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of wheat sowing machine, comprise frame 1, frame 1 front end is provided with hitch 4, seed broadcaster is connected with draw-gear (tractor) by hitch 4, frame 1 is provided with from front to back successively rotary cultivator attachment 5, dials native device 6, fertilizing and seeding apparatus, suppression device 8, described rotary cultivator attachment 5 is for being installed on the rotovator of frame 1 leading portion, described group of native device 6 is for being installed on the soil moving wheel at rotovator rear, and soil moving wheel comprises wheel, and 61, wheel shaft 61 is provided with cylinder soil moving wheel body 63, soil moving wheel body 63 is provided with blade 62, described fertilizing and seeding apparatus comprises the fertilizing mechanism of fertile the case 2 and its underpart being installed on frame 1 stage casing, and (fertilizing mechanism is prior art, depending on not going out in figure), kind of case 3 and its underpart broadcast sowing mechanism 7, described mechanism 7 of broadcasting sowing comprises the discharging tube 71 on top and the flow distribution plate 72 of bottom, flow distribution plate cross section is L-shaped, face is evenly equipped with multiple protruding 74 to L shape flow distribution plate hypomere plate, seed is uniformly distributed in the process of broadcasting sowing, L shape flow distribution plate hypomere both sides are provided with flanging 73 upwards, can ensure that seed evenly falls on L shape flow distribution plate, prevent seed from trickling down at flow distribution plate side, affect seed uniformity, described suppression device 8 comprises the suppression wheel shaft and press wheel (suppression device is prior art, is not described in detail at this) that are installed on frame back segment.The power of described rotary cultivator attachment 5 is provided by the draw-gear of seed broadcaster, dials native device 6 and passes through belt transmission with rotary cultivator attachment 5; Fertilizing mechanism, broadcast sowing mechanism 7 by chain with suppression device 8 be in transmission connection.
When the present invention works, seed broadcaster has tractor to draw, and tractor outputting power drives rotovator rotary tillage soil, when reaching certain rotary tillage degree of depth, the rotary power of press wheel is passed to fertilizing mechanism by multi-chain gear wheel, chain, is broadcasted sowing mechanism, and seed evenly scatters through broadcasting sowing mechanism.Drive soil moving wheel by rotovator by reverse drive band, soil moving wheel rotates when the mellow soil after rotary tillage is brought to peak position to be shed backward, covers on the seed sowed through discharging tube place.Adjustment additionally by discharging tube upper-lower position regulates the sowing depth of seed, ensures that seed has enough earthing amounts.The present invention by the configuration of soil moving wheel, broadcast sowing the uniform broadcasting of mechanism and the adjustment of discharging tube, what ensure seed broadcasts sowing uniformity, and suitable seed level, reaches and well sow effect.
