Description

Plant planter porose disc formula is sent kind of a mechanism

Technical field

The utility model belongs to leads the sower part field of planting and sowing, and relates generally to a kind of plant planter porose disc formula and send kind of a mechanism, can realize intermittently sending automatically kind.

Background technology

Plant planter is significant for the cultivating seeds test.The plant planter tool can improve the selection experiment operating efficiency, result of the test is more accurate.The sub-district sowing need be ready to the seed of different strains in advance, tests ten hundreds of often with the umber of seed.Sub-district sowing is different from general sowing, and its requirements finishes a certain amount of seed in particular cell length, and can not have remaining seed to stay in the seeding unit, makes the kind period of the day from 11 p.m. to 1 a.m of sowing another kind in next sub-district, unclear kind, not miscegenation.Yet domestic existing plant planter development falls behind, and automaticity is low, in the time of can not satisfying the sub-district sowing, and a large amount of unclear kinds of variety classes seed, miscegenation and the demand intermittently sent automatically kind.

Summary of the invention

The purpose of the utility model is to overcome the difficult point of sending kind of mechanism in the prior art in the plant planter; Provide a kind of and be applicable to what the sub-district was sowed; Simple in structure, easy to operate, practical porose disc formula is sent kind of a mechanism; Can realize that plant planter automatically intermittently send kind, and in the sowing process, needn't plant clearly, miscegenation not.

To achieve these goals, the invention provides following technical scheme:

A kind of plant planter porose disc formula send kind of a mechanism to comprise:

Plant alms bowl 7, said kind of alms bowl 7 is provided with opening on the bottom;

Central shaft 3, said central shaft 3 is positioned at the center of disk 2;

Disk 2, said disk 2 bottoms have groove 12;

Fixing hole 5, said fixing hole 5 are that the center of circle is circle-shaped layout and can centers on central shaft 3 rotations with central shaft 3;

Connecting rod 6, said connecting rod 6 two ends connect fixing hole 5 and disk 2 respectively;

Support porose disc 1, the bottom of said support porose disc 1 is fixedly mounted on fixing hole 5 belows, with the correspondence position of one of a plurality of fixing holes 5 be provided with one with being plugged on this fixing hole 5 bottom of interior kind alms bowl 7 is complementary send kind of mouth 4;

Positioner 8, be positioned at disk 2 the below, with frame 9 that the bottom of disk 2 is connected on, comprise spring 10 and circular bead 11.

Wherein, said kind of alms bowl (7) do not have the bottom.

The beneficial effect of the utility model is: the plant planter circular port disc type that the utility model provided send kind of mechanism structure simple; Easy to operate; Practical; Unclear kind when having realized that the variety classes seed is sowed in the sub-district is not sent kind the automatic intermittence of miscegenation, has effectively improved the operating efficiency of sub-district sowing.

Fig. 3 send the positioner working state schematic representation of kind of mechanism for the utility model plant planter porose disc formula.

Reference numeral

1. support porose disc; 2. disk; 3. central shaft; 4. send kind of a mouth; 5. fixing hole; 6. connecting rod; 7. kind alms bowl; 8. positioner; 9. frame; 10. spring; 11. circular bead; 12. groove.

Embodiment

Embodiment to the utility model describes below in conjunction with accompanying drawing.

Like Fig. 1,2 and shown in Figure 3; A kind of plant planter porose disc formula send kind of mechanism mainly to comprise to have disk 2 that the support porose disc 1 that send kind of mouth 4, bottom have groove 12, central shaft 3, be that the center of circle is circle-shaped layout and can connects connecting rod 6, the kind alms bowl 7 of fixing hole 5 and disk 2 respectively around a plurality of fixing holes 5, the two ends of central shaft 3 rotations and be positioned at the positioner 8 on the frame 9 with central shaft 3.

Plant alms bowl 7 and have the cross section that is complementary with fixing hole 5, be suitable for inserting in the fixing hole 5.Preferably, the cross section of kind alms bowl 7 is circular.Plant alms bowl 7 and have circle-shaped sidewall, it does not have the bottom or on the bottom, is provided with opening.

The bottom of supporting porose disc 1 is fixedly mounted on fixing hole 5 belows; Being provided with one with one correspondence position in a plurality of fixing holes 5 is complementary with the bottom that is plugged on the kind alms bowl 7 in this fixing hole 5 or smaller kind of the mouth 4 that send; Be plugged on the bottom and the pig that supports porose disc 1 of the kind alms bowl 7 in the fixing hole 5, make seed can be accommodated in kind of the alms bowl 7.

Positioner 8 is positioned at the below of disk 2, on frame 9 that the bottom of disk 2 is connected, is made up of spring 10 and circular bead 11.The pig of circular bead 11 and disk 2 during disk 2 rotations, spring 10 is depressed, like state I I (motion state) among Fig. 3; After turning over suitable angle, circular bead 11 snaps in the groove 12 that is positioned at disk 2 bottoms, and spring 10 is upspring, and disk 2 no longer rotates, like state I among Fig. 3 (positioning states).This device can prevent at the drive lower fixed hole 5 of connecting rod 6 under the situation of inertia or body vibrations, to rotate, and the seed that the seed that causes being about to sowing can not fall into or be about to sowing smoothly falls in advance and causes miscegenation.

The utility model is when work, and fixing hole 5 noncontinuities that disk 2 controls link to each other with connecting rod 6 are rotated.Kind alms bowl 7 in being inserted in fixing hole 5 rotate to support that porose disc 1 bottom is provided with send the correspondence position of kind of mouth 4 time, seed is fallen through sending kind of mouth 4 by kind of alms bowl 7.Cover a sub-district length when plant planter, finish one type of seed after, disk rotates to an angle rapidly, the kind alms bowl 7 that fills the new class seed forwards to and send kind of mouth 4 tops.Needn't plant clearly, miscegenation not, can accomplish automatically and intermittently send kind.
