Description

A kind of suction hole adjustable seed device

Technical field

The utility model relates to technical field of agricultural mechanical equipment, is specifically related to that a kind of suction hole is adjustable gets kind of a machinery.

Background technology

Sowing is important step in production estimation process, and seeding mechanization not only can boost productivity, liberation labour, and can improve productivity effect, promotes increasing both production and income.Getting kind of principle and can be divided into the large class of mechanical type and pneumatic type two by seeding apparatus, because air-suction type seed metering device requires tight to seed sizes, does not need selected classification, wound is planted few, easily realize simple grain program request, sower operating speed raising potentiality are large, obtained research and apply widely.The difference of object and cropping pattern is sowed in seeding process, different requirements is all had to the size of suction hole size, every seed number per and cave distance, the adjustment of existing air-aspiration type hole sowing machine generally adopts the mode changing the seeds sucker and duckbilled assembly with different suction hole quantity and different pore size to complete, because seeds sucker is arranged on hole sowing wheel inside, adjustment cave is apart from needing the replacing that parts dismounting just can be completed seeds sucker, therefore dismounting bothers very much, wastes time and energy, and have impact on the result of use of facility greatly.

Summary of the invention

The utility model is the weak point for avoiding existing for above-mentioned prior art, a kind of suction hole adjustable seed device is provided, this device can according to the requirement of cropping pattern and Seeding Quantity, by different liner is arranged on seeds sucker, regulate the adjustment of the suction hole position that seeds sucker participates in inhale kind and suction hole size, spacing, and then effectively achieve the change of seed size and every cave Seeding Quantity in seeding process, sowing cave distance.

The utility model is that technical solution problem adopts following technical scheme:

The design feature of a kind of suction hole adjustable seed device of the utility model is:

Seeds sucker (2) is set and air chamber (1) is inserted on the power transmission shaft (4) of sower; Described seeds sucker (2) and described power transmission shaft (4) are tight fit, can rotate with power transmission shaft; Described air chamber (1) empty set, on described power transmission shaft (4), is not rotated with power transmission shaft (4); Described seeds sucker (2) left surface embeds in air chamber (1), gap is had with described air chamber (1) concave side, can rotate relative to air chamber, its left side and described air chamber (1) recessed end face are fitted, and liner (3) end face of its right side and setting is fitted and links together.

The design feature of a kind of suction hole adjustable seed device of the utility model is also: seeds sucker (2) is for having the disk body of datum hole; Liner (3) is zonal and arc, there are two kinds of structures, structure one arranges hollow tightening pin (31) and suction hole (32), described suction hole (32) can be processed into the different through hole of shape, size or spacing as required, and described hollow tightening pin (32) inside arranges through hole and communicates with described suction hole (33); Structure two only arranges tightening pin (33), and described tightening pin (33) is solid post, in order to block the upper no datum hole of seeds sucker (2).

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model overall structure is simply novel, easy and simple to handle, time saving and energy saving; Be applicable to the smart seed-fetching of large seed, can require to carry out fast getting kind of an adjustment according to sowing, widen the scope of application of seeds sucker, improve seeding quality and efficiency, reduce labor intensity.

2, the utility model adopts structure seeds sucker being arranged datum hole, for rapid-assembling/disassembling liner provides matrix.

3, the utility model adopts lining structure, well achieve seed taking device not pull down from power transmission shaft, just realize getting the adjustment of kind of a hole size, size and spacing by seeds sucker being installed different liners, and then the adjustment realized to the seed of difformity and size and different Seeding Quantity, cave distance in seeding process, improve the operating efficiency of sower.

Number in the figure: 1 air chamber, 2 seeds suckers, 3 liners, 4 power transmission shafts, 31 hollow tightening pins, 32 suction holes, 33 tightening pins.

Embodiment

See Fig. 1 and Fig. 2, seeds sucker 2 is set and air chamber 1 is inserted on the power transmission shaft 4 of sower; Described seeds sucker 2 is tight fit with described power transmission shaft 4, can rotate with power transmission shaft; Described air chamber 1 empty set, on described power transmission shaft 4, is not rotated with power transmission shaft 4; Described seeds sucker 2 left surface embeds in air chamber 1, and have gap with described air chamber 1 concave side, can rotate relative to air chamber, its left side and the recessed end face of described air chamber 1 are fitted, and liner 3 end face of its right side and setting is fitted and links together.

In concrete enforcement, as shown in Figure 3, seeds sucker 2 is for having the disk body of datum hole; Liner 3 has two kinds of structures, as shown in Fig. 4, Fig. 5, Fig. 7, Fig. 8 and Fig. 9, structure one arranges hollow tightening pin 31 and suction hole 32, described suction hole 32 can be processed into the different through hole of shape, size or spacing as required, and described hollow tightening pin 31 inside arranges through hole and communicates with described suction hole 32; As shown in Figure 6, structure two only arranges tightening pin 33, and described tightening pin 33 is solid post, in order to block no datum hole on seeds sucker 2.

Operating process:

Before sowing, seeds sucker 2 and air chamber 1 are inserted on the power transmission shaft 4 of sower; According to plantation agronomy and seed size requirement, by the liner 3(that chooses as Fig. 5) shown in, insert on seeds sucker in datum hole, liner 3 is fixed in the datum hole of seeds sucker 2 by hollow tightening pin 31 and fits with seeds sucker 2, and common composition inhales kind of a through hole; Also insert shown in lining structure two (as Fig. 6), in order to block no datum hole on seeds sucker 2 simultaneously.For Fig. 1, the lining structure one of what on the datum hole of seeds sucker 2, outmost turns was inserted is band suction hole, what insert enclosed in the inside two is lining structure two not with suction hole, and illustrate, this seeds sucker once only broadcasts a kind; If need in a kind cave to broadcast 2 seeds, on the datum hole of seeds sucker 2, outermost 2 encloses what insert is the lining structure one of band suction hole, and what insert enclosed in the inside one is lining structure two not with suction hole, by that analogy, can complete the adjustment of Seeding Quantity; When Fig. 7 liner replaces Fig. 4 liner, the spacing of sowing and cave are apart from diminishing; When Fig. 8 liner replaces Fig. 4 liner, the spacing of sowing and cave are apart from becoming large; When Fig. 9 liner replaces Fig. 4 liner, the crop seed that diameter is larger can be broadcast.

During sowing, under power transmission shaft 4 drives, seeds sucker 2 rotates relative to air chamber 1, seed is adsorbed on the suction hole 32 on liner 3 under the effect of air chamber 1 negative pressure, and take the seed of absorption out of seed chamber, when forwarding dead slot region, air chamber 1 bottom to, because negative pressure disappears, the seed of absorption falls in seed box corresponding to lower end in the effect of deadweight, realizes getting kind of a process.This device by different liners 3 being arranged on adjustment seeds sucker 2 met to suction hole size shape and spacing, and then achieves the adjustment to Seeding Quantity and cave distance in the plantation of different plant species and seeding process.
