Detailed Description

For a better understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and the following embodiments.

Example 1

A seed sowing machine comprises a movable rack 10, wherein a vertical hole opening pipe 5 is arranged on the rack 10, a coaxial sowing pipe 2 is arranged inside the hole opening pipe 5, a fixed lantern ring 6 is arranged on the periphery of the lower portion of the hole opening pipe 5, four movable pieces 9 forming an inverted cone are hinged to the bottom of the hole opening pipe 5, a torsion spring 8 is arranged at the hinged position of the four movable pieces, a bayonet 13 with a clamping block 15 inside is arranged on the pipe wall of the rear side of the hole opening pipe 5, the pipe wall of the sowing pipe 2 is inwards sunken to form a clamping groove 14 for containing the clamping block 15, a spring a16 is arranged in the clamping groove 14, the groove wall above the clamping groove 14 is in an inclined plane shape, a stop block 17 for abutting against the external end of the clamping block 15 is arranged on the rear side of the hole opening pipe 5, a groove 18 is arranged on the stop block 17 below the clamping block 15, a spring b19 is arranged in.

The working principle is as follows: the whole seeding process of the frame 10 is carried out in the moving process of the frame 10, and the bottom of the seeding pipe 2 is at a certain distance from the bottom of the hole opening pipe 5. Firstly, the seeding tube 2 moves downwards under the driving of the driving mechanism 1, at this time, the fixture block 15 is matched with the clamping groove 14, the spring a16 is compressed, and the end of the fixture block 15 is blocked by the stop block 17 to keep the fixture block 15 matched with the clamping groove 14, so that the hole opening tube 5 moves downwards under the driving of the seeding tube 2. The movable sheet 9 at the bottom of the hole opening pipe 5 keeps the inverted cone-shaped posture and is inserted into the soil, and when the hole opening pipe 5 and the seeding pipe 2 integrally move to the fixture block 15 and the groove 18, the tail end of the fixture block 15 moves into the groove 18 under the elastic force of the spring a 16. As the sowing pipe 2 continues to descend, the inclined groove wall above the catching groove 14 applies an outward moving thrust to the catching block 15, and the catching block 15 further moves into the groove 18 until being separated from the catching groove 14, and simultaneously compresses the spring b 19. The dibbling tube 5 is then kept still by the cooperation of the latch 15, the bayonet 13 and the groove 18, and the sowing tube 2 continues to move downwards. When the bottom of the sowing pipe 2 moves to be in contact with and extruded by the movable sheets 9 at the bottom of the hole opening pipe 5, the four movable sheets 9 are turned outwards and opened under the action of the sowing pipe 2, so that soil is pushed outwards to form a seed hole, the sowing mechanism 4 in the sowing pipe 2 immediately throws down seeds, and the seeds vertically fall into the seed hole.

Then, the seeding tube 2 moves upwards under the action of the driving mechanism 1, the seeding tube 2 is separated from the movable plates 9, the four movable plates 9 turn inwards under the action of the torsion spring 8 to restore to form the inverted cone-shaped posture, when the seeding tube 2 moves upwards to the clamp groove 14 to correspond to the groove 18, the clamp block 15 moves out of the groove 18 under the action of the spring b19 and moves to be matched with the clamp groove 14, and then under the matching of the clamp block 15 and the clamp groove 14, the seeding tube 2 drives the hole opening tube 5 to ascend, so that the whole process of one-time seeding is completed, and the above steps are repeated to perform next-time seeding.

the spacing distance of the sowing can be controlled by controlling the intermittent operation of the driving mechanism 1 and matching with the moving speed of the frame 10.

The utility model discloses can carry out the automation in soil through opening cave pipe and seeding pipe and open cave and automatic seeding under the drive of actuating mechanism machine, pure mechanical structure dependable performance, the operation is stable, can realize the repetition of seeding operation under the condition of not adding extra outside power and go on, the amount of labour that has significantly reduced has improved seeding efficiency.

Example 2

The embodiment is improved on the basis of embodiment 1:

sowing mechanism 4 includes the open seeding groove 4.1 of the sunken tank bottom that forms of seeding pipe 2 left side pipe wall to inside oblique below, it is provided with fixed plate 4.2 to open on the pipe 5 right side inner wall of cave, fixed plate 4.2 end-to-end connection has the vertical baffle 4.3 of the 4.1 tank bottoms of closed seeding groove, set up the rectangular opening 3 that supplies fixed plate 4.2 to pass on the seeding pipe 2, open and set up the kind of a mouth 11 that falls that corresponds with seeding groove 4.1 notch on the pipe 5 of cave, kind of a mouth 11 that falls corresponds with outside seed conveying pipe 12.

The seeds in the seed conveying pipe 12 enter the sowing groove 4.1 through the seed dropping opening 11, the seeds in the sowing groove 4.1 cannot drop due to the existence of the baffle 4.3, and the seeds stored in the sowing groove 4.1 are the number of the seeds sowed at one time. When the seeding pipe 2 and the hole opening pipe 5 synchronously move downwards, the seed conveying pipe 12 is staggered with the seed falling port 11, the outer wall of the hole opening pipe 5 is kept sealed with the seed conveying pipe 12, at the moment, the baffle 4.3 and the seeding groove 4.1 are kept relatively static, and seeds in the seeding groove 4.1 still cannot fall. When the hole opening pipe 5 is static and the sowing pipe 2 continues to move downwards, the sowing grooves 4.1 move downwards relative to the baffle plates 4.3 to be separated from each other, seeds fall down when the bottoms of the sowing grooves 4.1 are opened, and the seeds fall into the sowing holes through the bottom of the hole opening pipe 5 and the sowing pipe 2, so that sowing is completed.

After the seeding is finished, the seeding pipe 2 rises, when the seeding pipe 2 and the hole opening pipe 5 rise again synchronously, the baffle 4.3 seals the bottom of the seeding groove 4.1 again, and the notch of the seeding groove 4.1 corresponds to the seed dropping opening 11 again. When the seed dropping port 11 rises to correspond to the seed conveying pipe 12, the seeds in the seed conveying pipe 12 enter the sowing groove 4.1 again through the seed dropping port 11, and then the next sowing can be carried out.

The improvement has the advantages that: the seeding groove, the baffle and the seed falling opening in the seeding mechanism are mutually matched, so that the seeding pipe and the hole opening pipe can automatically perform seed separation and seeding in the ascending and descending processes, the full-automatic seeding is realized, the precision control of the number of precision seeds is realized, and the seed waste is avoided.

Example 3

the embodiment is improved on the basis of the above embodiment:

Motor 1.4 drives carousel 1.3 vertical rotation, and the rotary motion of lug 1.2 on carousel 1.3 resolvable for vertical direction and the ascending motion of horizontal direction, the ascending motion of horizontal direction makes lug 1.2 round trip movement in spout 1.1, and the ascending motion of vertical direction drives connecting block 1.5 up-and-down motion for lug 1.2, and then can drive seeding pipe 2 up-and-down motion through connecting block 1.5.

Example 4

the embodiment is improved on the basis of the above embodiment:

The upper surface of the end of the latch 15 contacting the stopper 17 is inclined.

When the spring b19 pushes the latch 15 into the latch slot 14, the latch 15 may not be pushed out of the groove 18 completely, and further, when the latch 15 moves upward along with the seeding tube 2 and the hole-opening tube 5, the groove 18 may catch the end of the latch 15. The upper surface of the tail end of the fixture block 15 is designed to be in an inclined plane shape, when the tail end of the fixture block is clamped by the groove 18, the fixture block 15 can be further pushed out of the groove 18 by the inclined plane, further separation of the fixture block 15 and the groove 18 is achieved, and mutual blocking is avoided.
