Abstract
The utility model discloses an inlayed convex suction nozzle of a seeder drum. The inlayed convex suction nozzle comprises a drum rotary shaft mounted on a seeder frame, wherein a drum is mounted on the drum rotary shaft; a suction nozzle is mounted in the drum and provided with a suction hole. The inlayed convex suction nozzle is characterized in that the suction nozzle comprises a convex suction nozzle comprising a suction nozzle head and a suction nozzle seat; a seed suction hole is formed in the suction nozzle head; a conical air suction hole and a round air suction hole are formed in the suction nozzle seat and communicated with the seed suction hole to form the suction hole of the suction nozzle. According to the scheme, the design of the conical suction hole is adopted, so that the internal flow speed of the suction nozzle with the conical suction hole is 2-3 times that of a general suction nozzle, the adsorption performance of the suction nozzle is greatly improved, the phenomenon of a large amount of seeds formed due to irregular shapes of irregularly shaped seeds is avoided, the reseeding rate is greatly reduced, and the high-speed accurate sowing of the irregularly shaped seeds is realized.
Description
Technical field
The utility model relates to sower cylinder, particularly relates to a kind of inserted convex suction nozzle of sower cylinder, belongs to agricultural mechanical field, is specially adapted to the absorption of the special-shaped seeds such as tomato, capsicum, eggplant, muskmelon.
Background technology
Traditional sower cylinder, is all generally on cylinder wall, directly to offer sucker, and aperture is large, and suction is little, at absorption abnormity, plants the period of the day from 11 p.m. to 1 a.m, easily occurs hole or many phenomenons.Therefore, the applicant has developed a kind of name and has been called " with the sower cylinder of suction nozzle ", the utility model patent of patent No. CN201220448550.6, and principal character is to have suction nozzle in described cylinder peace, described suction nozzle exceeds the outer wall of cylinder, and suction nozzle is shaped with suction hole.Its advantage is that suction nozzle is a less projection, projection exceeds the outer wall of cylinder, after flat seed is by suction nozzle sorption, just attach on the suction nozzle head of suction nozzle hole and suction nozzle bore edges, only have seed just to be held in the center of suction nozzle, if depart from center, because the area being attached on suction nozzle is little, can automatically drop, so each suction hole only has a seed, the seed that avoids waste, reaches a kind of object in a cave.But the shortcoming existing is: described sucker is straight shape through hole, at the larger special-shaped seed of absorption, seeds such as tomato, capsicum, eggplant, muskmelon, under the long-pending condition of identical negative pressure, same cross-sectional, in the suction nozzle of linear through hole, flow velocity is not enough, and suction is little, seed is difficult for holding, and causes hole to occur.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of employing taper sucker design is provided, sucker suction flow velocity around is obviously improved, avoid irregular many phenomenons that form due to special-shaped seed, significantly lower replay rate, realize the inserted convex suction nozzle of sower cylinder of special-shaped seed high speed Precise sowing.
The technical scheme of the inserted convex suction nozzle of the utility model sower cylinder is: comprise the roller shaft being arranged on seeder frame, mounting rotary drum on roller shaft, in cylinder, be equipped with suction nozzle, suction nozzle is shaped with sucker, it is characterized in that described suction nozzle comprises the convex shape suction nozzle that suction nozzle head and suction nozzle seat form, in suction nozzle head, be shaped with and inhale kind of a mouth, be shaped with taper wind inlet and circular inlet scoop in suction nozzle seat, taper sucker, circular inlet scoop and suction kind of a mouth is communicated with the sucker that forms suction nozzle.
The inserted convex suction nozzle of sower cylinder of the present utility model, suction nozzle profile and sucker shape are improved to design, effectively solved a difficult problem for special-shaped planting seed, in identical negative pressure, under the long-pending condition of same cross-sectional, the interior flow velocity of the suction nozzle of taper sucker design is 2 to 3 times of common suction nozzle, greatly improved the absorption property of suction nozzle, so can use the less larger seed of aperture absorption, both avoided because irregular formation of special-shaped seed adsorbed many xenities simultaneously, reduce replay rate, can improve seeding accuracy due to the assurance of suction again, reduce hole rate.When removing unnecessary absorbed seed, the general mode that adopts malleation to blow is processed, when the flat suction nozzle of tradition forms many absorption, because some flat seeds and cylinder surface are tightly affixed, airflow direction has the trend that seed is pressed to cylinder surface, and seed is difficult for being blown off, and even convex suction nozzle has many adsorption phenomenas, the air-flow that malleation is blown is to blow to unnecessary seed from seed below, and seed is more easily blown off, and reduces replay rate.
The inserted convex suction nozzle of sower cylinder of the present utility model, described suction nozzle head and suction nozzle seat are made into integration by copper material, and one is easy to process, reduces assembly process, and copper material is antirust.The diameter of phi 1 of described circular inlet scoop is 3-5 times of the diameter of phi 2 of inhaling kind mouthful, and suction is large, and flow velocity is fast, high adsorption capacity.
Accompanying drawing explanation
Fig. 1 is the inserted convex nozzle structure of the utility model sower cylinder schematic diagram;
Fig. 2 is A-A schematic cross-section of Fig. 3;
Fig. 3 is that inserted convex suction nozzle of the present utility model is arranged on schematic diagram in cylinder.
Embodiment
The utility model relates to the inserted convex suction nozzle of a kind of sower cylinder, as shown in Fig. 1-Fig. 3, comprise the roller shaft 1 being arranged on seeder frame, on roller shaft 1, mounting rotary drum 2, in cylinder 2, be equipped with suction nozzle, suction nozzle is shaped with sucker, wherein, described suction nozzle comprises the convex shape suction nozzle 3 that suction nozzle head 31 and suction nozzle seat 32 form, in suction nozzle head 31, be shaped with and inhale kind of a mouth 33, in suction nozzle seat 32, be shaped with taper wind inlet 34 and circular inlet scoop 35, taper sucker 34, circular inlet scoop 35 and suction kind of a mouth 33 is communicated with the sucker 4 that forms suction nozzle.This programme improves design to suction nozzle profile and sucker shape, effectively solved a difficult problem for special-shaped planting seed, under the long-pending condition of identical negative pressure, same cross-sectional, the interior flow velocity of the suction nozzle of taper sucker design is 2 to 3 times of common suction nozzle, greatly improved the absorption property of suction nozzle, so can use the less larger seed of aperture absorption, both avoided because irregular formation of special-shaped seed adsorbed many xenities simultaneously, reduce replay rate, can improve seeding accuracy due to the assurance of suction again, reduce hole rate.When removing unnecessary absorbed seed, the general mode that adopts malleation to blow is processed, when the flat suction nozzle of tradition forms many absorption, because some flat seeds and cylinder surface are tightly affixed, airflow direction has the trend that seed is pressed to cylinder surface, and seed is difficult for being blown off, and even convex suction nozzle has many adsorption phenomenas, the air-flow that malleation is blown is to blow to unnecessary seed from seed below, and seed is more easily blown off, and reduces replay rate.Described suction nozzle head 31 and suction nozzle seat 32 are made into integration by copper material, are made into integration easy to processly, reduce assembly process, and copper material is antirust.The diameter of phi 1 of described circular inlet scoop 35 is to inhale kind 3-5 times of mouthfuls 33 diameter of phi 2, and suction is large, and flow velocity is fast, high adsorption capacity.
