Abstract

The utility model relates to a component of an agricultural seeder, and particularly relates to a seed sucking disc on an air sucking type seed taking machine used on an air sucking type seeder. The seed sucking disc disclosed by the utility model comprises a seed sucking disc (1) which is a circular sheet body and can be fixed on a negative pressure cavity or integrated with the negative pressure cavity, and the seed sucking disc (1) is provided with seed sucking holes (2); and the seed sucking disc is characterized in that: the inside area of a circumference formed at the center of each seed sucking hole (2) on the seed sucking disc (1) is provided with a plurality of bulges (3), the bulges (3) are fungiform bulges or serrated bulges or radial elongated bulges (3), and the bulges and the seed sucking disc (1) are fixedly connected or integrated, so that when the seed sucking disc (1) rotates, seeds in a seed filling cavity are always in a slack state. The seed sucking disc disclosed by the utility model has the advantages that: through arranging special-shaped bulges on the seed sucking disc as a stirring device, an effect of preventing the occurrence of a sucking leakage phenomenon is achieved, especially, for flat seeds such as seed melons and the like, the stirring effect is highlighted, so that the seed sucking efficiency of the seed sucking disc is obviously increased, and then the seed taking rate of precise seed taking is further improved.

Description

A kind of seeds sucker

Technical field

The utility model relates to a kind of agricultural seeding machine parts, the seeds sucker on the air-sucking type seed-taking device that uses on particularly a kind of pneumatic seeder.

Technical background

At present, pneumatic seeder is widely used in the seeding operation of precision agriculture, and the core technology of facility all concentrates on the air-sucking type precision weighing seed implement.The seeds sucker of the air-sucking type precision weighing seed implement of conventional art is to be plane and to be with some holes, during use, seeds sucker is located at the end face of vacuum cavity, and the two frictional fit is rotated and got kind.Also have a kind of be the utility model people design with the seeds sucker design with the vacuum cavity one or be fixedly connected, through rotation negative pressure cavity transmission realization precision drilling.When the air-sucking type seed-taking device is worked; Seeds sucker is all the time at vacuum cavity and fill between kind of the seat, and seeds sucker is the continuous absorbed seed of rotation in the seed heap, in actual use under the jolting effect in the facility traveling process; Fill that seed in kind of the seat is jolted easily and by closely knit; Seed usually is not easy to be picked up like this, and suction phenomenon occurs leaking, needs manual work to mix up with club sometimes.Technical staff of the same trade understands; More satisfactory adsorption effect should be that seed preferably is in more open state and is adsorbed easily; Therefore, the technical staff who has normally is provided with a disk shape at the center of seeds sucker wave dish solves this problem, but can not play the purpose that the seed in kind of the seat is filled in abundant stirring; Run into particularly that just to highlight mixing effect such as the melon flat seed of seed very poor, directly influence the adsorption effect of seeds sucker.

The utility model content

The purpose of the utility model is to address the above problem; Seeds sucker on a kind of air-sucking type seed-taking device is provided,, makes the seed that fills in kind of the seat be in more open state all the time through the column agitating device is set on seeds sucker; Realize the phenomenon that anti-leak-stopping is inhaled, improve kind of the rate of getting.

The purpose of the utility model is achieved in that

The utility model include one can be fixed on the negative pressure cavity or with the round sheet body-seeds sucker 1 of negative pressure cavity one; Be provided with suction hole 2 above that; The inside region of the circumference that the center forms of each suction hole 2 on seeds sucker 1 is provided with some protrusions 3; Protrusion 3 be shaped as the mushroom protrusion or for zigzag protrusion or strip protrusion 3 radially; Be fixedly connected or one between protrusion 3 and the seeds sucker 1, make the seed that when seeds sucker 1 rotation, fills in kind of the chamber be in relaxed state all the time; Described section is that the both sides of strip protrusion are circular-arc; Described mushroom protrusion or be the height b of zigzag protrusion or strip protrusion 3 radially between 2-15mm, further preferred b is at 4-10mm; The mushroom protrusion or by protruding center institute's formations circumference of zigzag protrusion or strip protrusion 3 radially or strip radially and suction hole 2 centers the radial spacing a of formation circumference be 10-28mm, further preferably radial spacing a is 12-18mm; Mushroom protrusion or for zigzag protrusion or strip protrusion 3 radially are distributed on the inner periphery of seeds sucker, the spacing of wherein any two adjacent protrusion is identical with spacing between any two adjacent suction holes 2.

The advantage of the utility model technology: the protrusion through given shape is set on seeds sucker is as agitating device; 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; Make the suction kind efficient of seeds sucker obviously improve, further improved smart kind of the rate of getting of planting of measuring.

Embodiment

Explain further details below in conjunction with the embodiment of accompanying drawing to the utility model.

Shown in accompanying drawing 1-6, the label among the figure is represented respectively: 1-seeds sucker, 2-suction hole, 3-protrusion, 4-installing hole, 11-vacuum cavity.

Embodiment 1

Like accompanying

drawing

1,2 signals; Present embodiment include one can be fixed on the negative pressure cavity or with the round sheet body-seeds sucker 1 of negative pressure cavity one; Be provided with suction hole 2 above that; The inside region of the circumference that the center forms of each suction hole 2 on seeds sucker 1 is provided with some mushroom protrusions 3, is fixedly connected through installing hole 4 between protrusion 3 and the seeds sucker 1, makes the seed that when seeds sucker 1 rotation, fills in kind of the chamber be in relaxed state all the time; The height b of described mushroom protrusion is 5mm; The radial spacing a of the circumference that the center forms of mushroom protrusion 3 and suction hole 2 circumference that the center forms is 13mm; Mushroom protrusion 3 is distributed on the inner periphery of seeds sucker, and the spacing of wherein any two adjacent protrusion is identical with spacing between any two adjacent suction holes 2.
