Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a multifunctional agricultural seeder. Background Technology
[0002] Seeding machines are planting machines that sow crop seeds. Seeding machines used for a specific type or crop are often named after the crop, such as grain row seeders, corn hill seeders, cotton seeders, and pasture broadcasters. The objects sown by seeders are crop seeds or coated seeds that have been pelleted. They can be classified into three categories according to their sowing method: vacuum seeders, broadcasters, row seeders, and hill seeders.
[0003] However, agricultural seeders in related technologies are not convenient for evenly and comprehensively sowing seeds, resulting in too many or too few seeds, which reduces the planting effect. Furthermore, it is inconvenient to bury the seeds after planting, leaving them exposed and affecting the survival rate. Therefore, we propose a multi-functional agricultural seeder to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a multifunctional agricultural seeder that can periodically and evenly sow seeds, thereby effectively controlling the sowing interval to avoid sowing being too concentrated or too sparse, which would reduce the sowing effect. After planting, the seeds can be buried to prevent some seeds from being exposed and affecting the survival rate.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-functional agricultural seeder includes a body, three hoppers are fixedly fitted inside the body, four support plates are fixedly connected to the bottom of the body, a rotating shaft is rotatably connected to the inner side of the support plates, a movable wheel is fixedly fitted to the outer side of the rotating shaft, three plowshares are fixedly connected to the bottom of the body, three seeding pipes are fixedly connected to the bottom of the body, the seeding pipes, plowshares and hoppers correspond to each other, an intermittent uniform seeding mechanism is provided between the body, the three hoppers and the rotating shaft on the left rear side, and a plowing and harrowing mechanism is provided on the right side of the body.
[0006] A further feature of this invention is that two traction plates are fixedly connected to the top of the machine body, and a connection hole is provided on the front side of the traction plate.
[0007] By adopting the above technical solution, it can be connected to the drive mechanism through the traction plate and the connecting hole.
[0008] A further feature of this invention is that the intermittent uniform seeding mechanism includes a lower sprocket fixedly connected to the rear side of a rotating shaft on the left rear side, and a drive shaft rotatably connected to the rear side of the machine body. An upper sprocket is fixedly connected to the rear end of the drive shaft. The upper sprocket and the lower sprocket are connected to the same chain for transmission. A turntable is fixedly connected to the front end of the drive shaft. A drive column is fixedly connected to the front side of the turntable. A transverse frame is slidably fitted on the outer side of the drive column. A sliding plate is fixedly connected to the bottom of the transverse frame. Three baffles are fixedly connected to one side of the sliding plate. Several feeding holes are opened on the top of the baffles. An flared groove is opened on the outer side of the feeding holes. The baffles are slidably fitted inside the hopper.
[0009] By adopting the above technical solution, as the device moves, the three plows can break up the soil. The moving wheel on the left rear side drives the rotation of the lower sprocket, which in turn drives the chain and the upper sprocket. The upper sprocket drives the rotation of the drive shaft and a turntable, which in turn drives the rotation of the drive column. The drive column drives the horizontal frame, the sliding plate, and the three baffles to reciprocate left and right. Under the baffles reciprocating left and right, when the feeding hole is connected to the seeding pipe, the seeds fall from the hopper into the seeding pipe and the newly opened furrow. When they are not connected, the seeds will not fall. Thus, the seeds can be sown intermittently in a periodic manner, which can effectively control the interval and density of seed sowing, avoiding sowing that is too dense or too sparse and thus reducing the planting effect.
[0010] A further feature of this invention is that sealing gaskets are fixedly connected to both sides of the hopper, and the baffle is movably abutted against the bottom of the sealing gaskets.
[0011] By adopting the above technical solution, it is convenient to provide a seal at the connection between the baffle and the hopper, thus preventing seeds from leaking out.
[0012] A further feature of this invention is that the intermittent uniform seeding mechanism includes several magnetic rods, with a sealing ring fixedly sleeved on the outer side of each magnetic rod. The sealing ring is movably inserted into the flared groove, and the magnetic rod is adsorbed and fixed in the corresponding feeding hole.
[0013] By adopting the above technical solution, the magnetic rod and the sealing ring can be adsorbed and fixed in the feeding hole according to actual needs, thereby adjusting the number of feeding holes and thus adjusting the spacing and density of seed planting.
[0014] A further feature of this invention is that a guide rod is fixedly connected to one inner wall of the machine body, the transverse frame is slidably sleeved on the outside of the guide rod, and the transverse frame and the machine body are fixedly connected to the same return spring.
[0015] By adopting the above technical solution, an initial force can be provided through the reset spring, which can prevent jamming when stopping and improve the smoothness of the baffle's left and right reciprocating movement.
[0016] A further feature of this invention is that the plow mechanism includes two connecting plates fixedly connected to one side of the machine body, a movable plate rotatably connected to the bottom of each of the two connecting plates, a common mounting plate fixedly connected to the bottom of the two movable plates, a plurality of rake nails fixedly connected to the bottom of the mounting plate, a common buffer spring fixedly connected between the movable plate and the connecting plate, two fixed plates fixedly connected to the bottom of the connecting plate, and the movable plate rotatably connected between the two fixed plates.
[0017] By adopting the above technical solution, the planting trenches can be leveled by setting up the mounting plate and rake nails, so that the exposed seeds can be buried in the soil. The buffer spring can buffer and protect the rake nails, preventing them from being damaged by hard objects such as stones.
[0018] The beneficial effects of this utility model are:
[0019] 1. As the device moves, the three plows break up the soil. The moving wheel on the left rear side drives the rotation of the lower sprocket, which in turn drives the chain and the upper sprocket. The upper sprocket drives the rotation of the drive shaft and a turntable, which in turn drives the rotation of the drive column. The drive column drives the horizontal frame, the sliding plate, and the three baffles to reciprocate left and right. Under the baffles reciprocating left and right, when the feeding hole is connected to the seeding pipe, the seeds fall from the hopper into the seeding pipe and the newly opened furrow. When the connection is not made, the seeds will not fall. Thus, the seeds can be sown intermittently in a periodic manner, which can effectively control the interval and density of seed sowing, avoiding sowing that is too dense or too sparse and thus reducing the planting effect.
[0020] 2. According to actual needs, this utility model can adsorb and fix the magnetic rod and the sealing ring in the feeding hole, thereby adjusting the number of feeding holes and thus adjusting the spacing and density of seed planting.
[0021] 3. This utility model, through the installation of the mounting plate and the rake nail, can level the furrows after planting, thereby burying the exposed seeds in the soil. The buffer spring can buffer and protect the rake nail, preventing it from being damaged by hard objects such as stones. Attached Figure Description

The installation plate 76 and the rake nail 75 can be used to rake the furrow after planting, thus burying the exposed seeds in the soil. The buffer spring 73 can buffer and protect the rake nail 75, preventing it from being damaged by hard objects such as stones.
