Description

Technical Field

[0001] This utility model belongs to the field of agricultural production technology, and in particular relates to a crop seeder. Background Technology

[0002] In the process of agricultural modernization, crop seeders, with their automated operation characteristics, have significantly improved sowing efficiency and effectively reduced the labor intensity of farmers, becoming an indispensable piece of equipment in agricultural production. However, with the continuous increase in the demand for precision and efficiency in agricultural production, existing crop seeders have revealed many problems that urgently need to be addressed.

[0003] From the perspective of the sowing mechanism, some traditional seeders adopt an extensive sowing method, and the seed conveying channel is not designed reasonably, which causes the seeds to accumulate and block during the falling process, resulting in uneven sowing density in the field.

[0004] In addition, in the soil sealing process, traditional soil sealing components have a simple structure, mostly soil sealing plates or wheels with fixed angles and shapes, which cannot flexibly adjust the soil covering thickness according to the actual situation, and the soil sealing is uneven. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a crop seeder that solves the problems of poor seeding quality and inability to flexibly adjust the soil covering thickness according to the actual situation in existing crop seeders.

[0006] The present invention adopts the following technical solution:

[0007] The device includes a frame with a pair of front and rear wheels facing downwards, and a handrail at the rear end. Its features include: a material box on the frame with a pair of bottom openings on the bottom; a sowing mechanism corresponding to each bottom opening on the frame; a sowing box containing a rotatable seeder with a sowing groove; a rotating shaft on the frame; two seeders mounted on the rotating shaft; a pair of connecting frames facing downwards; a circular tube at the bottom of each connecting frame; an iron plow and a soil-sealing assembly at the front and rear of the circular tube, respectively; a flexible hose connected to the outlet of the sowing box; and a drive mechanism on the frame for rotating the rotating shaft.

[0008] Furthermore, the soil sealing assembly includes a soil sealing fork rotatably mounted on a circular tube, an adjusting rod rotatably mounted on the soil sealing fork, a connecting plate located above the soil sealing fork on the circular tube, an oblong groove on the connecting plate, the adjusting rod located in the oblong groove, and an adjusting nut screwed into the top of the adjusting rod, and a spring located below the connecting plate on the adjusting rod.

[0009] Furthermore, the axle of the front drive wheel is provided with a driven wheel and a linkage wheel respectively. The frame is provided with a bearing seat, and a pair of coaxially connected drive wheels are rotatably mounted on the bearing seat. A rotating wheel is provided on the rotating shaft. The drive mechanism includes a gasoline engine mounted on the frame. A drive wheel is provided on the drive shaft of the gasoline engine. Matching belts are fitted between the drive wheel and the driven wheel, between the linkage wheel and one of the drive wheels, and between the other drive wheel and the rotating wheel.

[0010] Furthermore, a scraper is provided above the seeding box facing the seeder.

[0011] The beneficial effects of this utility model are:

[0012] 1. This device integrates ditching, sowing, and soil covering functions into one unit, reducing equipment changeover time, significantly improving sowing efficiency, and reducing farmers' labor intensity and equipment usage costs.

[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figure 1-3As shown, the device includes a frame 1 with a pair of front and rear wheels 2 facing downwards, and a handrail 3 at the rear end. The device is characterized by: a material box 4 on the frame 1 with a pair of bottom openings on the bottom; a sowing mechanism corresponding to the bottom openings on the frame 1; a sowing box 5 containing a sowing device 6 rotatably mounted inside the sowing box 5; a sowing groove 7 on the sowing device 6; a rotating shaft 8 rotatably mounted on the frame 1; two sowing devices 6 mounted on the rotating shaft 8; a pair of connecting frames 9 facing downwards on the frame 1; a round tube 10 at the bottom of the connecting frame 9; an iron plow 11 and a soil sealing assembly respectively positioned at the front and rear of the round tube 10; a flexible hose 12 connected to the outlet of the sowing box 2; the bottom of the flexible hose 12 passing through the round tube 10 on the same side; and a drive mechanism on the frame 1 for rotating the rotating shaft 8.

[0022] In the process of modern agricultural production, sowing is a crucial initial step in crop planting, and its quality and efficiency have a decisive impact on the final yield and quality of crops.

[0023] The frame serves as the carrier of this device. As shown in the diagram, a pair of front and rear wheels are installed at the bottom of the frame, a handrail is installed at the rear of the frame, and a material box is installed on top of the frame. The material box is used to store crop seeds. The bottom of the material box has a pair of symmetrical bottom openings. The seeding box is connected to the bottom opening of the material box on the same side. A seeder is rotatably installed inside the seeding box, and the two seeders are coaxially connected by a rotating shaft.

[0024] When using this device to sow crops, the operator first pours the seeds into the feed hopper. The operator holds the handles with both hands, and the drive mechanism rotates the rotating shaft, while the traveling wheels move forward. Driven by the rotating shaft, the two seeders on the left and right also rotate. During the rotation of the seeders, the seeding troughs sequentially scoop seeds from the bottom opening of the feed hopper. When the seeding trough containing seeds rotates to the outlet position of the seed box, the seeds fall through the flexible hose into the furrows prepared by the plow. As the seeper continues to move, the soil-sealing component covers the seed furrows with soil.

[0025] As a specific structure, such as Figure 4 The sealing assembly includes a sealing fork 13 rotatably mounted on a circular tube 10, an adjusting rod 14 rotatably mounted on the sealing fork 13, a connecting plate 15 located above the sealing fork 13 on the circular tube 10, a slotted groove on the connecting plate 15, the adjusting rod 14 located in the slotted groove, and an adjusting nut 16 screwed into the top of the adjusting rod, and a spring 17 located below the connecting plate 15 on the adjusting rod 14.

[0026] In this device, the soil-sealing assembly has a compact structure. The soil-sealing fork is rotatably mounted on a circular tube, and the soil-sealing end of the fork has a U-shaped structure. During actual sowing, the position of the adjusting rod on the connecting plate can be changed by turning the adjusting nut, thereby adjusting the position of the soil-sealing fork and the pressure on the ground, achieving flexible adjustment of the soil covering thickness. The soil-sealing fork contacts the ground under the preload of the spring to perform the soil covering operation. During the soil covering operation, the adjusting rod will make slight up-and-down displacements as the soil-sealing fork encounters different terrains or soil resistance, to buffer the impact on the soil-sealing fork and ensure smooth soil covering. Simultaneously, during sowing, if it is necessary to adjust the soil covering thickness, the operator can change the position of the adjusting rod by turning the adjusting nut, thereby adjusting the position of the soil-sealing fork.

[0027] Throughout the sowing process, the scraper above the sowing box remains in contact with the seeder, promptly removing excess seeds from the surface of the seeder to ensure an accurate number of seeds in each sowing trough, guaranteeing uniformity and precision in sowing, and efficiently completing crop sowing operations.

[0028] As a preferred structure, such as Figure 1-2 The front drive wheel 2 has a driven wheel 18 and a linkage wheel 19 on its axle. The frame 1 has a bearing seat 20, and a pair of coaxially connected drive wheels 21 are rotatably mounted on the bearing seat 20. The rotating shaft 8 has a rotating wheel 22. The drive mechanism includes a gasoline engine 23 mounted on the frame 1. The drive shaft of the gasoline engine 23 has a drive wheel 24. The drive wheel 24 and the driven wheel 18, the linkage wheel 19 and one of the drive wheels, and the other drive wheel and the rotating wheel are all fitted with matching belts 25.

[0029] In the diagram, a driven wheel and a drive wheel are mounted on the axle of the front traveling wheel. A bearing housing is installed on the frame, and a pair of coaxially connected drive wheels are rotatably mounted on the bearing housing. A rotating wheel is mounted on the rotating shaft. During sowing, the gasoline engine mounted on the frame is first started. The drive wheel on the gasoline engine's drive shaft drives the driven wheel on the axle of the front traveling wheel via a belt, causing the seeder to begin moving. Simultaneously, the drive wheel transmits power to one of the drive wheels on the bearing housing via a belt. Ultimately, the rotating wheel on the rotating shaft rotates under the linkage of the other drive wheel, thus achieving synchronous rotation of the two seeders.

[0030] In addition, a scraper 26 is provided above the seeding box facing the seeder. During the rotation of the seeder, the scraper 26 can promptly scrape off excess seeds from the surface of the seeder, ensuring that the number of seeds in each seeding trough is consistent, and further improving the seeding accuracy.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
