Abstract

The utility model discloses a vegetable sowing machine, wherein front and rear traveling wheels, sowing legs and sowing machine are mounted on a frame; the sowing machine adopts a structure that a rotating plate is mounted at the bottom of a seed storing box, sowing holes are formed at the bottom of the seed storing box and the rotating plate respectively, and the rotating plate is connected to a rotating shaft through a lock nut; the sowing machine is connected with the sowing legs through sowing pipes, one traveling wheel is in mechanical transmission with the rotating plate of the sowing machine, a compression spring is arranged below the lock nut, and the contact surface of the rotating plate and the bottom of the sowing machine are in elastic contact with each other through the compression spring; an adjusting plate is arranged on the rotating plate, and the adjusting plate is rotated to adjust the right/wrong position of the sowing holes on the rotating plate and the adjusting plate; and an earth covering scraper is arranged at the rear part between every two sowing legs. By virtue of the vegetable sowing machine provided by the utility model, the sowing amount can be adjusted, which is convenient to apply; and the seeds can be covered completely through the earth covering scraper, thereby improving the rate of emergence.

Description

Vegetable-seed planter

Technical field

The utility model relates to agricultural machinery, relates in particular to sower.

Background technology

The vegetable-seed planter that present vegetable grower uses, main structure is road wheel before and after being equipped with on frame, sowing leg and some seeders, the rolling disc of seeder is fixed tightly on the turning cylinder with locking nut, each seeder is connected with some sowing legs by the pipe of sowing, the seed tray machine driving of one of them road wheel and seeder realizes the quantitative and even sowing.The front and back road wheel of existing sower generally is a drum-type, seeder generally is a disc type, disc type seeder structure is in the bottom of containing kind of case rolling disc to be installed, contain difference lower seed hole on kind of case bottom and the rolling disc, when rotating disk rotates under transmission device drives, as long as the lower seed hole of case bottom and rotating disk is aimed at, just fall quantitative seed, seed enters the pipe of sowing.Find to have following deficiency through using:

1, because the rolling disc of seeder is fixed tightly on the turning cylinder with locking nut, and making it is tight formula with containing kind of the contact-making surface of case bottom, produces shearing force and extruding force during the lower seed hole relative motion, some seed that has little time to fall is easy to squeeze broken.

2, since the lower seed hole diameter on the rolling disc fix, when the kinds of sowing vegetables not simultaneously, the varying in size of seed, thickness of sowing is also different, so seeding quantity is different, therefore needs to change rolling disc, and is very inconvenient.

In addition, existing vegetable-seed planter makes the seed that disseminates be exposed at ground surface owing to after planting can not cover voluntarily, and the germination of can not burying influences emergence rate.

Summary of the invention

The utility model is to overcome the defective that existing vegetable-seed planter destroys the seed integrity degree easily, and a kind of improved vegetable-seed planter is provided.

For achieving the above object, the concrete scheme that the utility model is taked is: a kind of vegetable-seed planter, structure is road wheel before and after being equipped with on frame, sowing leg and seeder, the seeder structure is in the bottom of containing kind of case rolling disc to be installed, contain on kind of case bottom and the rolling disc and be respectively equipped with lower seed hole, rolling disc is connected on the turning cylinder with locking nut; Seeder is connected with the sowing leg by the pipe of sowing, the rolling disc machine driving of one of them road wheel and seeder, it is characterized in that: be provided with compression spring below locking nut, making rolling disc by compression spring is that flexible type contacts with the contact-making surface of seeder bottom.

In order to regulate the seeding quantity of various vegetable varieties, on rolling disc, be provided with an adjustment disk, adjustment disk is provided with and the corresponding lower seed hole of rolling disc lower seed hole, adjustment disk is provided with 2-3 arc adjustment hole, adjustment disk is laminated on the rolling disc with screw by the arc adjustment hole, the mistake that the rotation adjustment disk is regulated the lower seed hole on rolling disc and the adjustment disk is to the position, thus the caliber size of regulating lower seed hole; When the lower seed hole of two dishes does not misplace, the big maximum of the amount of sowing, it is big more to misplace, and the amount of sowing is more little;

For cover-seeding ditch voluntarily, the rears between per two sowing legs are provided with the earthing scraper plate.

The utility model operation principle and good effect are:

1, when the seed in the seeder has little time, rolling disc has loosening trend under spring action, can not push seed by force or shear seed, and seed is not destroyed;

2, according to the kind difference of vegetables, can rotate angle of adjustment disk, make adjustment disk cover lower seed hole go-no-go on the rolling disc, regulate the amount of sowing, needn't change rolling disc, it is convenient to use;

3, owing to be provided with the earthing scraper plate, seed is covered fully, improved emergence rate.

Embodiment

As shown in Figure 1, structure of the present utility model is: road wheel (not drawing among the figure), sowing leg 1 and seeder 5 before and after being equipped with on frame 2, seeder 5 structures are in the bottom of containing kind of case rolling disc 6 to be installed, contain on kind of case bottom and the rolling disc 6 and be respectively equipped with lower seed hole 4, rolling disc 6 usefulness locking nuts 7 are connected on the turning cylinder 9; Seeder 5 is connected with each sowing leg 1 by the pipe 3 of sowing, and one of them road wheel is by rolling disc 6 machine driving of mechanism driving device 11 with seeder; Wherein:

Be provided with compression spring 8 below locking nut 7, making rolling disc 6 by compression spring 8 is that flexible type contacts with the contact-making surface of seeder 5 bottoms;

On rolling disc 6, be provided with an adjustment disk 10 (the adjustment disk structure as shown in Figure 2), adjustment disk 10 be provided with the lower seed hole 4 corresponding lower seed holes 4 of rolling disc 6 ', adjustment disk 10 is provided with 2-3 arc adjustment hole 13, by arc adjustment hole 13 usefulness screws adjustment disk 10 is laminated on the rolling disc 6, rotate adjustment disk 10 regulate lower seed hole 4 and lower seed hole 4 ' mistake to the position, thereby the size of regulating lower seed hole 4 bores;
