Description

Technical Field

[0001] The utility model relates to the technical field of seeders, in particular to an openable and closable seeder. Background Art

[0002] A seeder is an agricultural tool used to plant seeds in the soil. They are commonly used for large-scale planting of crops such as wheat, corn, soybeans, etc. The working principle of the seeder is to transport the seeds from the container into the arranged teeth or grooves, and then place the seeds in the soil through rotation or mechanical action. The main function of the seeder is to evenly distribute the seeds in the soil to ensure that the crops receive proper spacing and nutrition during the growing season.

[0003] Existing seeders generally do not have an opening and closing mechanism, lack flexibility and precision, and a seeder that cannot be opened and closed may only be able to sow seeds evenly over the entire field and cannot accurately control the amount of sowing, which may lead to seed waste and unnecessary planting density, thereby affecting crop growth and yield. In some places where sowing is not required, a seeder that cannot be opened and closed may not be able to stop sowing in these places, resulting in a waste of resources and difficulties in planting management. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing seeder generally has no opening and closing mechanism, and the amount of sowing cannot be accurately controlled, which may cause waste of seeds.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: an openable and closable seeder, including a lower shell, a seeder wheel is arranged in the lower shell, a rotating sleeve is rotatably connected to the outside of the seeder wheel, a through hole is opened on the rotating sleeve, a first motor is fixedly connected to one side of the lower shell, the output end of the first motor rotates through the lower shell and the rotating sleeve, and the output end of the first motor is fixedly connected to the seeder wheel.

[0006] Through the above technical solution, by adjusting the rotation of the rotating sleeve, farmers can accurately control the release amount of seeds according to the seed size or sowing density of different crops, avoid over- or under-sowing, ensure uniform distribution of seeds, and reduce waste.

[0007] The utility model is further configured as follows: an arc-shaped groove is opened on one side of the lower shell body, a tooth block is arranged in the arc-shaped groove, the tooth block is fixedly connected to the rotating sleeve, a gear is rotatably connected to one side of the lower shell body, the gear and the tooth block are meshed with each other, a limit block is arranged on one side of the gear, the limit block and the gear cooperate with each other, and a second motor is fixedly connected to the side of the gear away from the lower shell body.

[0008] Through the above technical solution, the limit block cooperates with the gear so that the gear is fixed and limited and will not rotate, so that the rotating sleeve is fixed and will not shake, thereby achieving precise sowing and avoiding seed waste and unnecessary planting density.

[0009] The utility model is further configured as follows: a fixing plate is fixedly connected to one side of the lower shell, a connecting shaft is slidably passed through the fixing plate, one end of the connecting shaft is fixedly connected to a limit block, a sliding groove is opened on one side of the lower shell, a sliding block is slidably connected in the sliding groove, and the sliding block is fixedly connected to the limit block.

[0010] The utility model is further configured such that a pull rod is fixedly connected to the side of the connecting shaft away from the limit block, a return spring is sleeved on the connecting shaft, two ends of the return spring are respectively fixedly connected to the limit block and the fixed plate, and the limit block, the connecting shaft and the pull rod are integrated.

[0011] The utility model is further configured as follows: an upper shell is arranged above the lower shell, the upper shell is rotatably connected to one side of the lower shell by a hinge, the other side of the upper shell is fixedly connected to the lower shell by a bolt and nut assembly, and a feed pipe is fixedly connected to the top of the upper shell.

[0012] Through the above technical solution, the upper shell and the lower shell can be disassembled and installed by disassembling and installing the bolt and nut assemblies. When repair or replacement of parts is needed, only the damaged or faulty parts need to be replaced without replacing the entire seeder as a whole, and farmers can more easily enter the interior of the seeder for maintenance and cleaning.

[0013] The utility model is further configured that a discharge port is arranged on a side of the lower shell away from the upper shell, and a plurality of seed retaining plates are fixedly connected to the seeding wheel.

[0014] Through the above technical solution, the seed retaining plate can ensure that the seeds are evenly distributed on the soil surface during the sowing process. By controlling the release amount of seeds through the teeth, the sowing density can be controlled more accurately to avoid seed waste. Therefore, by adjusting the spacing and number of teeth, the seed density in the field can be ensured to be uniform, avoiding overly dense or sparse sowing.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The utility model is provided with a rotating sleeve, which is matched by a gear and a tooth block to control the rotation angle of the rotating sleeve, thereby controlling the overlapping area of ​​the through hole on the rotating sleeve and the drop opening, so as to accurately control the release amount of seeds, avoid excessive or insufficient sowing, and thus save seed costs. When turning or passing through irregularly shaped fields, farmers can adjust the rotating sleeve as needed to ensure uniform distribution of seeds, and in areas where sowing is not required, the rotating sleeve completely blocks the drop opening, avoiding wasting seeds outside the field or in areas where sowing is not required, thereby reducing seed waste;

[0017] 2. The utility model sets a limit block. After the adjustment of the rotating sleeve is completed, the limit block is stuck in the gear to limit the movement of the gear, so that the rotating sleeve is fixed and will not shake. The overlap area and opening degree of the through hole on the rotating sleeve and the blanking port caused by vibration or unstable operation are reduced, which affects the sowing effect, effectively prevents the occurrence of seed waste, and maintains the stability of the seeder.
