Abstract
The utility model relates to a part of an agricultural planter, and in particular relates to a seed sucking disc on an air-suction type seed-taking device which is used in an air-suction type seeder. The seed sucking disc comprises a round sheet-shaped seed sucking disc body (10) which can be fixed on a negative pressure cavity or can be integrated with the negative pressure cavity, wherein a plurality of seed sucking holes (11) are formed in the seed sucking disc body, and is characterized in that a boss (17) is arranged at each seed sucking hole (11) in the seed sucking disc body (10); the seed sucking holes (11) penetrate through the center of the boss (17). Due to the adoption of the boss (17), seeds in a seed changing cavity are always located in a loose state when the seed sucking disc (1) rotates. The seed sucking disc has the following advantages that through using the boss arranged at each seed sucking hole of the seed sucking disc as a stirring device, each boss is configured to be in a cone shape or horn mouth shape, the projecting sucking ports are relatively convenient for sucking flat seeds such as seed melon, and therefore, the seed-taking rate of a precise seed-taking process is further improved.
Description
Technical field
The utility model relates to the seeds sucker on the air-suction type seed metering device using on a kind of agricultural seeding machine parts, particularly a kind of pneumatic seeder.
Technical background
At present, pneumatic seeder is widely used in the seeding operation of precision agriculture, and the seeds sucker of the air-suction type precision seed extractor of conventional art is to be plane and to be with some holes, during use, seeds sucker is located to the end face of vacuum cavity, the two frictional fit is rotated and is got kind.Also having a kind of is the utility model people design seeds sucker is designed with vacuum cavity one or is fixedly connected with, and by the transmission of rotation negative pressure cavity, realizes precision drilling.When air-suction type seed metering device is worked, seeds sucker is all the time at vacuum cavity and fill between kind of seat, seeds sucker is the continuous absorbed seed of rotation in seed heap, in actual use under the effect of jolting in facility traveling process, fill that seed in kind of seat is easily jolted and by closely knit, seed is usually not easy to be picked up like this, and suction phenomenon is leaked in appearance, so usually need manually with club, to mix up, more satisfactory adsorption effect should be that seed is preferably easily adsorbed in more open state, particularly run into that such as the melon flat seed of seed, just to highlight mixing effect very poor, directly affect the adsorption effect of seeds sucker.At on 02 26th, 2012, the inventor has applied for that to State Intellectual Property Office a key name is called a kind of patent of invention of seeds sucker, the patent No. 201110265569.7, open day: on 07 11st, 2012, described technology contain one can be fixed on negative pressure cavity or with round sheet body--the seeds sucker of negative pressure cavity one, be provided with suction hole thereon, the inside region of the circumference that center forms of each suction hole on seeds sucker arranges the Song Zhongzhu of some columns, pine is planted between post and seeds sucker and is fixedly connected, make moment when suction is planted can make to be adsorbed seed in relaxed state.Advantage is: by column agitating device is set on seeds sucker, realize the phenomenon that anti-leak-stopping is inhaled, particularly run into such as the melon flat seed of seed and just highlight mixing effect, the suction kind efficiency of seeds sucker is obviously improved, further improved kind of the rate of getting of smart seed-fetching.
Utility model content
The purpose of this utility model is at a kind of modified of above-mentioned prior art, seeds sucker on a kind of air-suction type seed metering device is provided, by the suction hole place at seeds sucker, boss is set, play the effect of stirring seed, make to fill seed in kind of seat all the time in more open state, realize the phenomenon that anti-leak-stopping is inhaled, improve kind of the rate of getting.
The purpose of this utility model is achieved in that
The utility model include one can be fixed on negative pressure cavity or with the seeds sucker 10 of the round sheet body of negative pressure cavity one, be provided with suction hole 11 thereon, each suction hole 11 place on seeds sucker 10 are boss 17, suction hole 11 runs through the heart portion of boss 17; The boss 17 of described each suction hole 11 on seeds sucker 10 is round table-like or bell mouth shape, and larger opening is towards seeds sucker; The height of the boss 17 of described each suction hole 11 on seeds sucker 10 is between 3-10mm.
The advantage of the utility model technology: the boss 17 arranging by each the suction hole place at seeds sucker is as agitating device, boss 17 is round table-like or horn mouth, the suction inlet of its protrusion is more convenient for absorption such as the melon flat seed of seed, has further improved kind of the rate of getting of smart seed-fetching.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Label in accompanying drawing 1-4 represents respectively: hold one's breath slide block, 8-screw, 9-kind case, 10-seeds sucker, 11-suction hole, 12-of 1-negative pressure cavity, 2-vacuum cavity gear, 3-hollow shaft, 4-negative pressure channel 5-negative pressure through-hole, 6-negative pressure cavity, 7-fills kind of a chamber, 13-bolt, 14-bearing chamber, 15-half circular shaft, 16-locknut, 17-boss.
As accompanying drawing 1,2,3,4 signals, the utility model includes a seeds sucker 10 that can be fixed on negative pressure cavity, is provided with suction hole 11 thereon, and each suction hole 11 place on seeds sucker 10 are boss 17, and suction hole 11 runs through the heart portion of boss 17; The boss 17 of described each suction hole 11 on seeds sucker 10 is bell mouth shape; The height of the boss 17 of described each suction hole 11 on seeds sucker 10 is 6mm.
When the utility model is used, with reference to accompanying drawing 1, 2, include a round sheet body-seeds sucker 10 that can be fixed on negative pressure cavity 1, hollow shaft 3, fill kind of chamber 12, planting case 9 forms, seeds sucker 10 is arranged on vacuum cavity 1 one sides by screw 8, negative pressure cavity 1 is provided with vacuum cavity gear 2, in the middle of vacuum cavity, by bearing, hollow shaft 3 is installed, hollow shaft 3 inside are provided with negative pressure channel 4, negative pressure channel 4 communicates by negative pressure through-hole 5 vacuum cavities, seeds sucker 10 is centrally located in the end of hollow shaft 3 by bearing block 14, the opposite side of seeds sucker 10 is filled kind of chamber 12 and is planted case 9 by half circular shaft and locknut location and installation, during work, by the rotation of cylinder, drive vacuum cavity gear 2 to rotate, vacuum cavity gear 2 drives negative pressure cavity 1 to rotate, vacuum cavity 1 drives seeds sucker 10 to rotate, the seed that the rotation of the boss 17 on seeds sucker makes to fill in kind of chamber 12 is loosening, simultaneously under the operation of negative-pressure air fan, by the negative pressure channel 4 in hollow shaft 3, negative pressure through-hole 5, extract gas in negative pressure cavity 1 out outside, make the interior formation negative pressure of negative pressure cavity 1, negative pressure makes to fill kind of an indoor seed and is adsorbed on (outer face of boss) on the suction hole 11 in boss 17, and when the boss 17 of absorbed seed turns to the position of the slide block 7 of holding one's breath, seed loses negative pressure, effect at self gravitation falls in corresponding with it inoculating seed transfusion box, by duck mouth, is sown in ground.
Although more than set forth with reference to accompanying drawing having done to elaborate according to the design of the utility model object and example; but those of ordinary skills can recognize; do not departing under the precondition of claim limited range; still can make various improvement and conversion to the utility model, and this improvement and conversion still should belong to protection domain of the present utility model.
