Seeder with speed limit function

Abstract

The invention relates to a seeder with a speed limit function. The seeder with a speed limit function includes a support shaft, a handle, two moving wheels, two first bearings and at least two seedingboxes, and also includes two speed limiting mechanisms and two anti-blocking mechanisms, wherein each speed limiting mechanism includes a support sleeve, a second bearing, a first gear, a second gear, a drive shaft, a second gravity block, a third bearing, two detection components and two execution components, each anti-blocking mechanism includes at least two sliding rods and at least two firstgravity blocks, and each detection component includes a guide rail, a sliding sleeve, a contact switch and a spring; and each execution component includes an air cylinder and a friction block. According to the seeder with a speed limit function, the seeding boxes can be driven to shake through the anti-blocking mechanisms, the probability that seeds are clogged inside a seeding tube is reduced, and the seeding effect of the seeder is improved; and the moving speed of the seeder can be limited through the speed limiting mechanisms, and the seeding effect of the seeder is further improved.

Description

technical field [0001] The invention relates to the field of seeding equipment, in particular to a seeder with a speed limiting function. Background technique [0002] The sower is a planting machine that uses crop seeds as the sowing object. The seeder used for a certain type or a certain crop is often named by the name of the crop type, such as grain drill, corn hole seeder, cotton seeder, pasture spreader, etc. In the 1st century BC, China has popularized the use of columbine, which is the earliest drill implement in the world, and it is still used in the dry farming areas in the north today. [0003] When the seeder in the prior art is in use, if the seeder moves too fast, the seeds will lean against the inner wall of the seed box under the action of centrifugal force, so that the seeds cannot fall into the farmland, and the performance of the seeder is reduced. Sowing effect, not only that, when the prior art sower is in use, if a large number of seeds pour into the s...

[0003] When the seeder in the prior art is in use, if the seeder moves too fast, the seeds will lean against the inner wall of the seed box under the action of centrifugal force, so that the seeds cannot fall into the farmland, and the performance of the seeder is reduced. Sowing effect, not only that, when the sower of the prior art is in use, if a large number of seeds are poured into the sowing tube at the same time, it will cause the seeds to block the inside of the sowing tube, further reducing the sowing effect of the sowing device
