Abstract

The utility model belongs to the technical field of agricultural machinery and relates to a seed metering device for a hole sower. The utility model comprises a rotating shaft and a moving disk arranged on the rotating shaft. Duckbill orderers are evenly arranged on the circumferential wall of the moving disk. An inner disk is arranged coaxially inside the moving disk, and a fixed disk is arranged on one side of the inner disk. The disc constitutes the seed chamber, and the circumferential wall of the inner disc is provided with a seeding trough corresponding to the duckbill seeder. piece. The utility model has the advantages of simple structure, reliable operation and reasonable design. The seeds are pre-taken through the seeding troughs distributed on the circumferential wall of the inner disk, and then the seeds are sent to the duckbill seeder for sowing by controlling the rotating cover on the seeding troughs, so that the seeds can be planted. It is sent to the duckbill on-demand device in time, so as to solve the problems of uneven seeding and missed reseeding. The baffle is used to block the excess seeds in the seed chamber, prevent the excess seeds from being discharged after the rotating cover is opened, and ensure the sowing accuracy.

Description

hole seeder

technical field

The utility model belongs to the technical field of agricultural machinery and relates to a seed metering device for a hole sower.

Background technique

Sowing is one of the basic links of agricultural production. The quality of sowing directly affects the emergence and growth of crops. The seed meter is the core of the hole seeder, and its working quality is even more important to the quality and efficiency of agricultural production. It has a great impact; the existing hole seeder is in the process of self-running, relying on gravity and inertia to enter the seed from the seeding port, and then discharge it with the duckbill on-demand device, because the hole seeder shakes violently during the sowing process Or the sowing speed is too fast, and the seeds cannot enter the seeding port in time, resulting in uneven seeding by the seed metering device, resulting in reseeding or missed sowing.

Utility model content

The purpose of the utility model is to provide a seed metering device for an auger that can accurately control the amount of seeds and sow evenly in order to solve the problems in the prior art.

The utility model relates to a seed metering device for hole sowers, which includes a rotating shaft and a moving disk arranged on the rotating shaft. Duckbill on-demand seeders are evenly arranged on the circumferential wall of the moving disk. An inner disk is coaxially arranged in the moving disk. The inner disk is a A fixed plate is arranged on the side, and the inner plate and the fixed plate form a seed chamber. The circumferential wall of the inner plate is provided with a seeding trough corresponding to the duckbill on-demand device. The seeding port of the seeding trough is provided with a rotating cover. The lower end of the fixed plate is provided with a protrusion corresponding to the rotating cover;

The fixed disk is fixed to the rotating shaft, so that the fixed disk remains stationary;

A baffle is arranged obliquely in the seed chamber, and the lower end of the baffle is tangent to the circumferential inner wall of the inner disk;

The baffle is fixed on the fixed plate;

The rotary cover is hinged to the seed discharge port, and a spring is provided at the hinge for resetting the rotary cover.

The utility model has the following beneficial effects:

The utility model has the advantages of simple structure, reliable operation and reasonable design. The seeds are pre-taken through the seeding troughs distributed on the circumferential wall of the inner disk, and then the seeds are sent to the duckbill seeder for sowing by controlling the rotating cover on the seeding troughs, so that the seeds can be planted. It is sent to the duckbill on-demand device in time, so as to solve the problems of uneven seeding and missed reseeding; the baffle is used to block the excess seeds in the seed chamber, prevent the excess seeds from being discharged after the rotating cover is opened, and ensure the sowing accuracy.

Detailed ways

As shown in Fig. 1 and Fig. 2, a seed metering device for a hole seeder comprises a rotating shaft 1, a moving disk 2 arranged on the rotating shaft 1, duckbill seeders 3 are evenly arranged on the peripheral wall of the rotating disk 2, and the moving disk 2 An inner disc 4 is arranged on the inner coaxial, a fixed disc 5 is arranged on one side of the inner disc 4 and the fixed disc 5 is fixed on the rotating shaft 1, the inner disc 4 and the fixed disc 5 form a seed chamber 6, and the peripheral wall of the inner disc 4 is provided with a The seeding trough 7 corresponding to the duckbill sower 3, the seeding port of the seeding trough 7 is hinged with a rotating cover 8 and the hinge is provided with a retaining ring, and the lower end of the fixed plate 5 is provided with a protrusion corresponding to the rotating cover 8. Block 9: a baffle 10 is installed obliquely in the seed chamber 6 and the baffle 10 is fixed to the fixed plate 5 , and the lower end of the baffle 10 is tangent to the circumferential inner wall of the inner plate 4 .

 The baffle plate 10 of the present utility model divides the seed chamber 6 into two parts , one part is equipped with seeds, and the other part has no seeds; when carrying out sowing operation, the moving disk 2 and the inner disk 4 rotate coaxially, the fixed disk 5 maintains its value and remains stationary, and the seed chamber 6 The seeds fall into the seed slot 7 in advance under the action of gravity and inertia. When the seed slot 7 passes through the lower end of the baffle plate 10, the baffle plate 10 intercepts the redundant seeds on the part of the seed chamber 6 containing the seeds. On the inner plate 4 The seeding chute 7 is then rotated to the bump 9 at the lower end of the fixed plate 5. Since the rotating cover 8 of the seeding chute 7 is in contact with the bump 9 to form an opening moment, the rotating cover 8 opens and the seeds fall into the duckbill seeder 3 for sowing Work, when the seeding groove 7 on the inner disk 4 leaves the projection 9 at the lower end of the fixed disk 5, the rotating cover 8 resets and closes under the action of the retaining spring.
