Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural implements, and specifically relates to a pasture seed sowing device. BACKGROUND

[0002] The smart pasture factory fully integrates advanced technologies of various disciplines such as biotechnology, information technology, engineering technology, clean energy, big data and artificial intelligence technology under the development trend of digital agriculture, simulates a pasture planting environment, and makes the growth of pasture not dependent on natural resources such as land, climate and sunlight, and is suitable for agricultural production in extreme climate environments in the northwest region (such as the northwest region, deserts, islands and the like).

[0003] The pasture produced in the smart pasture factory is usually grown in a seedling tray in an indoor planting system, and the planting system is composed of a mobile planting platform, a spraying and humidifying device, a pesticide spraying device, a fertilizing device, a light supplementing system and an intelligent electric control system. The pasture seeds are transported with the mobile planting platform and are influenced by the spraying and humidifying device, the pesticide spraying device, the fertilizing device and the light supplementing system for cultivation. Sowing the pasture seeds into the seedling tray is also an indispensable step for cultivating the pasture. However, artificial sowing or machine sowing is generally used in the prior art. The artificial sowing has a large workload and low work efficiency. The common machine sowing usually adopts a broadcasting mode, and needs to be further improved. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the utility model aims at overcoming the defects in the prior art, and provides a pasture seed sowing device. The technical scheme is as follows.

[0005] The utility model discloses a seed bin is provided with the seed bin bottom's discharge gate, the discharge gate bottom is provided with the seed bin bottom's discharge gate, and the discharge gate bottom is provided with the seed bin bottom's discharge gate.

[0006] The linkage structure comprises a pull rod hinged with the sowing head and a rotating rod fixedly connected with the valve rod of the discharge valve.

[0007] The discharge valve comprises a valve shell fixedly connected with the discharge gate, a valve ball arranged in the valve shell, and a valve rod penetrating the valve shell and fixedly connected with the valve ball.

[0008] The bottom outlet of the seeding head is inserted into the soil along the downward sliding of the outlet, and the seeds are discharged into the seeding head through the outlet, and then the seeds fall into the soil through the outlet at the bottom of the seeding head, thereby achieving the operation of sowing the seeds into the soil. By arranging the linkage structure, when the seeding head moves downward relative to the outlet, the pull rod is driven to move downward, the pull rod drives the rotating rod to rotate, the rotating rod drives the valve rod and the valve ball to rotate, the perforation in the center of the valve ball is communicated with the internal passage of the outlet, and the seeds can be discharged through the perforation. That is, when the seeding head moves downward to prepare for sowing, the discharge valve is automatically opened for discharging, and the discharge valve does not need to be controlled by the electric control.

[0009] The seed bin is provided with an inlet, and a cover is arranged on the inlet to seal the inlet.

[0010] The seed bin is communicated with an inflator, the inflator is provided with a piston push rod for pushing gas into the seed bin, and a one-way valve is arranged between the inflator and the seed bin. The piston push rod of the inflator is connected to the seeding head through a synchronous push-pull structure.

[0011] The synchronous push-pull structure comprises a push-pull cylinder arranged on the piston push rod, the push-pull cylinder is connected to the seeding head, the bottom of the push-pull cylinder is closed, the upper end of the push-pull cylinder has a necking portion, and a compression spring is arranged between the piston push rod and the necking portion.

[0012] When the seeding head moves downward, the push-pull cylinder is driven to move downward. When the through hole of the ball valve in the discharge valve is not communicated with the outlet, the seed bin is in a sealed state. Due to the gas pressure, the piston push rod is difficult to push the gas into the seed bin, that is, the piston push rod remains stationary or moves slightly, so that the compression spring between the necking portion of the push-pull cylinder and the piston push rod is compressed. As the seeding head continues to move downward, the through hole of the ball valve in the discharge valve is communicated with the outlet, and the elastic force of the compression spring drives the piston push rod to move, so that the gas is pushed into the seed bin. The seeds in the seed bin are pushed into the outlet under the gas pressure, and the discharging is promoted. That is, when the seeding head moves downward to prepare for sowing, and the discharge valve is opened for discharging, the inflator injects gas into the seed bin to promote the discharging of the seeds in the seed bin. By arranging the synchronous push-pull structure, the electric control for controlling the inflator is not needed.

[0013] Further comprising a driving cylinder, the cylinder base of the driving cylinder is connected to the seed bin, a push block is fixed on the movable rod of the driving cylinder, and the push block is fixedly connected to the seeding head and the push-pull cylinder through a connecting rod.

[0014] The driving cylinder is arranged as a driving element for driving the movement of the seeding head and the push-pull cylinder.

[0015] A connecting base is further fixed on the outer wall of the seed bin, and the connecting base is used for mounting the seeding device on other machines.

[0016] By setting the connecting pedestal, the seeding device is conveniently installed as a working part on a moving structure or an operating structure such as a moving platform, a horizontal slide or a mechanical hand.

[0017] In summary, due to the adoption of the technical scheme, the present application has the advantages of:

[0018] The seed can be automatically seeded into the soil, and the seeding position is accurate.
