Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, in particular to a sowing device for agricultural machinery and a use method thereof. Background Art

[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry. The science that studies agriculture is agronomy. The objects of agricultural labor are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture is a basic industry that provides support for the construction and development of the national economy.

[0003] Existing sowing devices for agricultural machinery, such as a seeder with adjustable sowing spacing disclosed in Chinese Patent Publication No. CN117859474B, can effectively improve the actual sowing effect by generating grooves required for sowing on the ground through plow claws and then placing seeds into the grooves through a discharge head.

[0004] However, compared with the existing technologies in the related fields, when the soil is relatively moist, mud is more likely to adhere to the plow claws. As the seeder is used for a longer time, mud will accumulate on the surface of the plow claws, thereby aggravating the adhesion of the mud. If mud adheres to the plow claws for a long time, it may change the depth of the furrowing and affect the sowing depth of the seeds. The existing device cannot automatically clean the mud attached to the plow claws during sowing, and thus needs to be constantly stopped for cleaning, which will affect the sowing efficiency of the device and increase the labor intensity of the staff. Summary of the invention

[0005] The object of the present invention is to solve at least one of the technical drawbacks.

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background technology, and provide a seeding device for agricultural machinery and a method of using the same.

[0007] The objective of the present invention is achieved through the following technical solutions: a sowing device for agricultural machinery, comprising a frame, on which a plurality of feeding mechanisms are installed, the frame is provided with discharging mechanisms located below the plurality of feeding mechanisms, plow claws are installed at the bottom of the plurality of discharging mechanisms, and the plurality of discharging mechanisms are provided with driving components for controlling the longitudinal reciprocating movement of the plow claws, moving wheels are installed at both ends of the frame, and a chain transmission structure is provided on the moving wheel corresponding to one side of the frame, and the chain transmission structure is used to control the discharging of the feeding mechanism.

[0008] Preferably, the discharging mechanism includes a suspension fixedly mounted on the frame, the front and rear sides of the suspension near the bottom are rotatably provided with rotating wheels, the rear side of the suspension is provided with a covering piece via a metal chain, and a discharging pipe is installed inside the suspension.

[0009] Preferably, the plow claw is slidably matched with the discharge pipe through a sliding column, the sliding column is fixedly connected to the discharge pipe, and a movable groove is provided at the position of the plow claw corresponding to the sliding column.

[0010] Preferably, the driving assembly includes a rotating shaft that cooperates with the suspension for rotation and a movable shaft that cooperates with the suspension for longitudinal sliding. A support for controlling the movable shaft to slide back and forth is fixedly arranged on one side of the rotating shaft close to the movable shaft, and a transverse straight groove is provided at the position of the movable shaft corresponding to the support.

[0011] Preferably, one end of the rotating shaft passes through the suspension, and the end of the rotating shaft passing through the suspension is cooperatively connected with one of the rotating wheels through a sprocket transmission mechanism.

[0012] Preferably, the sprocket transmission mechanism includes a first gear fixedly connected to the rotating shaft, a second gear is fixedly provided on the side of the rotating wheel located on the front side of the suspension close to the first gear, the first gear and the second gear are connected through chain conditions, and a cover plate is fixedly installed on the side of the suspension close to the chain conditions.

[0013] Preferably, a rotation hole is provided at one end of the rotation shaft of the suspension, and the end of the rotation shaft is matched and connected to the rotation hole via a bearing.

[0014] Preferably, a sliding block is fixedly provided on one side of the suspension away from the rotating hole, a sliding groove matching with the sliding block is provided at a position of the movable shaft corresponding to the sliding block, and the shape of the sliding block is T-shaped.

[0015] Preferably, a screw is threadedly passed through the movable shaft transversely, and a plurality of insertion holes are longitudinally provided at positions of the plow claws corresponding to the screws.

[0016] A method for using a seeding device for agricultural machinery comprises the following steps:

[0017] S1. When in use, first connect the frame to a tractor or other mobile vehicle, and then pour the seeds into the hopper of the discharge mechanism;

[0018] S2. After the seeds are poured in, the frame is moved by a tractor or other mobile vehicle. At this time, the plow claws will plow a hole in the soil, and then the rotation of the moving wheel cooperates with the chain transmission structure to control the discharge mechanism to discharge the seeds, so that the seeds are discharged from the discharge pipe;

[0019] S3. When the rotating wheel rotates due to friction with the ground, the sprocket transmission mechanism can be used to allow the rotating shaft to rotate with it, so that the cooperation between the support and the transverse straight groove can make the rotating shaft rotate one circle and the movable shaft can slide up and down once;

[0020] S4. When the movable shaft slides up and down, the screw and one of the sockets cooperate to allow the plow claw to slide up and down with it, so that the soil attached to the surface of the plow claw can rub against the soil, effectively increasing the friction frequency of the attached soil, so that the soil attached to the surface of the plow claw can automatically fall off. At the same time, the up and down reciprocating sliding of the plow claw can improve its plowing effect and enhance the practicality of the equipment;

[0021] S5. When the height of the plow claw needs to be adjusted, the screw is rotated to disengage it from the socket, and then the height of the plow claw can be adjusted as needed. After the adjustment is completed, the screw can be engaged with the corresponding socket so that the plow claw can still move up and down.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] The seeding device for agricultural machinery can allow the plow claw to slide back and forth up and down by setting a driving component, so that the soil attached to the surface of the plow claw can rub against the soil, effectively increasing the friction frequency of the attached soil, so that the soil attached to the surface of the plow claw can automatically fall off, and at the same time, the up and down reciprocating sliding of the plow claw can improve its plowing effect and enhance the practicability of the equipment.

[0037] Additional aspects and advantages of the present invention will be further given in the following description in conjunction with the accompanying drawings, and in part will become apparent from the following description, or may be learned through practice of the present invention.

[0039] As a preferred technical solution of the present invention, the discharging mechanism 3 includes a suspension 301 fixedly mounted on the frame 1, and rotating wheels 302 are rotatably provided on the front and rear sides of the suspension 301 near the bottom. A covering piece 303 is installed on the rear side of the suspension 301 through a metal chain, and a discharging pipe 304 is installed inside the suspension 301.

[0040] As a preferred technical solution of the present invention, the plow claw 4 slides with the discharge pipe 304 through the slide post 401, the slide post 401 is fixedly connected to the discharge pipe 304, and a movable groove 402 is opened at the position of the plow claw 4 corresponding to the slide post 401.

[0041] As a preferred technical solution of the present invention, the driving component 5 includes a rotating shaft 501 that rotates with the suspension 301 and a movable shaft 502 that slides longitudinally with the suspension 301.

A transverse straight groove 504 is provided at a position of the movable shaft 502 corresponding to the support 503. A screw 5023 is threadedly connected transversely through the movable shaft 502. A plurality of sockets 403 are longitudinally provided at a position of the plow claw 4 corresponding to the screw 5023. When the height of the plow claw 4 needs to be adjusted, the screw 5023 is rotated to disengage the socket 403, and then the height of the plow claw 4 can be adjusted according to the needs. After the adjustment, the screw 5023 can be matched with the corresponding socket 403, so that the plow claw 4 can still move back and forth up and down.

[0042] As a preferred technical solution of the present invention, one end of the rotating shaft 501 passes through the suspension 301, and one end of the rotating shaft 501 passing through the suspension 301 is connected to one of the rotating wheels 302 through a sprocket transmission mechanism 8. The sprocket transmission mechanism 8 includes a first gear 801 fixedly connected to the rotating shaft 501, and a second gear 802 is fixedly provided on a side of the rotating wheel 302 located on the front side of the suspension 301 close to the first gear 801.

[0048] S3, such as Figures 6 to 8 As shown, when the rotating wheel 302 rotates due to friction with the ground, the sprocket transmission mechanism 8 is used to allow the rotating shaft 501 to rotate with it, so that the cooperation between the support 503 and the horizontal straight groove 504 allows the rotating shaft 501 to rotate one circle and the movable shaft 502 to slide up and down once;

[0049] S4, such as Figures 8 to 10 As shown, when the movable shaft 502 slides up and down, the screw 5023 cooperates with one of the insertion holes 403 to allow the plow claw 4 to slide back and forth with it, so that the soil attached to the surface of the plow claw 4 can rub against the soil, effectively increasing the friction frequency of the attached soil, so that the soil attached to the surface of the plow claw 4 can automatically fall off, and at the same time, the up and down reciprocating sliding of the plow claw 4 can improve its plowing effect and enhance the practicality of the equipment;
