Description

Technical Field

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

[0002] A seeder is an agricultural machine used to sow seeds evenly in a field, which can greatly improve planting efficiency and crop yield.

[0003] Most seeders have several drawbacks in use. For example, if the seeds are not treated after sowing, their growth rate and health may be severely affected, leading to uneven or slow crop growth. Furthermore, most seeders require workers to dig planting trenches before use, a cumbersome step that reduces overall sowing efficiency. Therefore, we propose a seeder for agricultural production. Utility Model Content

[0004] The purpose of this invention is to provide a seeder for agricultural production to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a seeder for agricultural production, comprising a housing and several planing plates, and further comprising:

[0006] A sliding groove is formed inside the housing, and a first sliding block is slidably installed inside the sliding groove. Several of the soil-scraping plates are fixedly installed at the bottom of the first sliding block.

[0007] A driving component, located within the housing, is used to drive the first sliding block to slide.

[0008] Two storage cavities are provided, both of which are located within the housing. A rotating column is rotatably mounted in one of the storage cavities, and a plurality of first grooves are provided on the circumferential sidewall of the rotating column. A cylinder is rotatably mounted in the other storage cavity, and a plurality of first discs are fixedly mounted on the cylinder. The plurality of first discs are rotatably connected to the other storage cavity, and a plurality of second grooves are provided on the circumferential sidewall of the plurality of first discs.

[0009] Two connecting posts are rotatably mounted inside the housing, and rollers are fixedly mounted at both ends of the two connecting posts;

[0010] A power assembly, located within the housing, is used to drive the cylinder and the rotating column to rotate.

[0011] In this technical solution, when the entire device is needed, the worker first pushes it onto the field, then pours the seeds into the storage chamber at the front and the wood ash into the storage chamber at the rear. Next, the casing is pushed, and several soil-digging plates move across the field, creating several planting troughs. Simultaneously, four rollers rotate, each driving two connecting columns to rotate. A power component drives the cylinder to rotate, which in turn drives several first discs to rotate. As the first discs rotate, the seeds in the front storage chamber enter the corresponding second grooves. Under the influence of the rotating first discs, the seeds in the second grooves eventually enter the planting troughs, automatically sowing the seeds. The power component also drives a rotating column to rotate, causing the wood ash in the rear storage chamber to enter the corresponding first groove. Under the influence of the rotating column, the wood ash eventually enters the planting troughs. The wood ash is rich in potassium, phosphorus, calcium, and other nutrients, providing comprehensive nutrient support for the seeds, and eliminating the need for workers to manually dig out the planting troughs.

[0012] When the depth of the planting trough needs to be adjusted, the first sliding block can be driven to slide downwards by the set drive component. The first sliding block drives several soil-scraping plates to move downwards. When the soil-scraping plates are moved to the appropriate position, the position of the soil-scraping plates can be fixed by the set drive component, which makes it convenient to adjust the depth of the planting trough and the operation is simple and convenient.

[0013] In the above technical solution, the driving component further includes:

[0014] Two connecting rods are rotatably installed in a sliding groove. The two connecting rods are rotatably connected and are distributed in a cross pattern. A second sliding block is rotatably installed at both ends of the two connecting rods. The two lower second sliding blocks are slidably connected to the first sliding block, and the two upper second sliding blocks are slidably connected to the sliding groove.

[0015] A threaded rod is rotatably mounted in a sliding groove and located on one side of the two upper second sliding blocks. One end of the threaded rod passes through the two upper second sliding blocks and extends to the outside. The threaded rod has two sections of threads with opposite directions of rotation, and the threaded rod is threadedly connected to the two upper second sliding blocks.

[0016] In this technical solution, when it is necessary to adjust the depth of the planting trough, the operator can rotate the threaded rod and drive the second disc to rotate. Under the action of the thread, the two upper second sliding blocks slide and move closer to each other. The two upper second sliding blocks will squeeze the two connecting rods to rotate. The two connecting rods will squeeze the two lower second sliding blocks to slide and move closer to each other on the top of the first sliding block. Then the first sliding block will slide down, and the first sliding block will drive several soil-scraping plates to move downward, which facilitates the adjustment of the depth of the planting trough and is simple and convenient to operate.

[0017] In the above technical solution, the driving component further includes:

[0018] The second disc is fixedly mounted on the threaded rod and rotatably connected to the sliding groove. Several limiting grooves are provided on the circumferential side wall of the second disc. A sliding column is slidably mounted in the sliding groove and above the second disc. The lower end of the sliding column extends into the corresponding limiting groove and is inserted into the corresponding limiting groove. Several tension springs fixed to the inner wall of the sliding groove are fixedly mounted on the sliding column. The upper end of the sliding column passes through the sliding groove and extends to the outside.

[0019] In this technical solution, when the sliding column is pulled upward, several tension springs are stretched and extended, and the lower end of the sliding column disengages from the corresponding limiting groove.

[0020] When the sliding column is released, it slides downward under the tension of several springs until the lower end of the sliding column is inserted into the corresponding limiting groove, which can fix the position of the second disc and prevent the threaded rod from rotating.

[0021] In the above technical solution, the power component further includes:

[0022] Two first transmission wheels are fixedly installed on one of the connecting columns and one end of the cylinder, respectively. A first transmission belt is installed between the two first transmission wheels, and both first transmission wheels are rotatably connected to the housing.

[0023] Two second transmission wheels are fixedly mounted on the other end of the cylinder and one end of the rotating column, respectively. A second transmission belt is installed between the two second transmission wheels, and both second transmission wheels are rotatably connected to the housing.

[0024] In this technical solution, when the entire device is needed, the worker first pushes it onto the field, then pours seeds into the storage chamber located at the front and wood ash into the storage chamber located at the rear. Next, the casing is pushed, and several soil-scraping plates move across the field, creating several planting troughs. Simultaneously, four rollers rotate, each driving two connecting columns. One connecting column drives one of the first transmission wheels, which in turn drives a first transmission belt. This first transmission belt drives another first transmission wheel, which in turn drives a cylinder. The cylinder then drives several first discs to rotate. As the first discs rotate, the storage chamber located at the front... The seeds inside the cavity will enter the corresponding second groove. Under the action of the rotation of several first discs, the seeds in several second grooves will eventually enter several planting troughs, which can automatically sow the seeds. At the same time, the cylinder drives one of the second transmission wheels to rotate, one of the second transmission wheels drives the second transmission belt to rotate, the second transmission belt drives another second transmission wheel to rotate, and the other second transmission wheel drives the rotating column to rotate. The wood ash in the rear storage cavity will enter the corresponding first groove. Under the action of the rotating column, the wood ash will eventually enter the planting trough. The wood ash is rich in potassium, phosphorus, calcium and other nutrients, which can provide comprehensive nutrient support for the seeds, and there is no need for staff to manually dig out the planting trough.

[0025] In the above technical solution, further, a plurality of the first grooves are distributed in an annular and equally spaced manner on the rotating column, a plurality of the second grooves are distributed in an annular and equally spaced manner on a plurality of first disks, and a plurality of the limiting grooves are distributed in an annular and equally spaced manner on the second disk.

[0026] In this technical solution, it is ensured that the seeds and wood ash can fall evenly, and that the second disc can stop rotating and be fixed at any position.

[0027] In the above technical solution, the number of the plurality of soil-scraping plates is the same as the number of the plurality of first discs, and the plurality of soil-scraping plates are distributed at equal intervals on the first sliding block.

[0028] In this technical solution, it is ensured that all seeds can fall into the planting trough, guaranteeing uniform planting.

[0029] In the above technical solution, an operating disc is further fixedly installed at one end of the threaded rod.

[0030] In this technical solution, the control panel is designed to facilitate the operation of staff.

[0031] The beneficial effects of this utility model are:

[0032] 1. This agricultural seeder has several soil-scraping plates that can create several planting troughs on the field. Simultaneously, four rollers rotate, each driving two connecting columns. A power unit drives a cylindrical column to rotate, which in turn drives several first discs to rotate. As the first discs rotate, seeds in the front storage chamber enter corresponding second grooves. The rotation of the first discs then directs the seeds from the second grooves into the planting troughs, automatically sowing the seeds. The power unit also drives a rotating column, causing wood ash in the rear storage chamber to enter corresponding first grooves. The rotating column then directs the wood ash into the planting troughs. Wood ash is rich in potassium, phosphorus, calcium, and other nutrients, providing comprehensive nutritional support for the seeds, and eliminating the need for manual digging of the planting troughs.

[0033] 2. When the depth of the planting trough needs to be adjusted, the first sliding block can be driven downward by the set drive component. The first sliding block drives several soil-scraping plates to move downward. When the soil-scraping plates are moved to the appropriate position, the position of the soil-scraping plates can be fixed by the set drive component, which facilitates the adjustment of the depth of the planting trough and is simple and convenient to operate.

[0081] Working principle: When the entire device is needed, the operator first pushes it onto the field, then pours seeds into the storage chamber 5 at the front and wood ash into the storage chamber 5 at the rear. Next, the operator pushes the housing 1, causing several soil-scraping plates 4 to move across the field, creating several planting troughs. Simultaneously, four rollers 10 rotate, driving two connecting columns 9 to rotate. One connecting column 9 drives one first transmission wheel 20 to rotate, which in turn drives a first transmission belt 21. The first transmission belt 21 drives another first transmission wheel 20, which in turn drives a cylinder 7 to rotate. The cylinder 7 then drives several first discs 8 to rotate. As the first discs 8 rotate, the planting troughs at the front are... The seeds in cavity 5 will enter the corresponding second groove 22. Under the action of the rotation of several first discs 8, the seeds in several second grooves 22 will eventually enter several planting troughs, which can automatically sow the seeds.

After the lower end of the sliding column 16 disengages from the corresponding limiting groove 15, the operator can rotate the operating disc 18 and drive the threaded rod 13 and the second disc 14 to rotate. Under the action of the thread, the two upper second sliding blocks 12 slide and move closer to each other. The two upper second sliding blocks 12 will squeeze the two connecting rods 11 to rotate. The two connecting rods 11 will squeeze the two lower second sliding blocks 12 to slide and move closer to each other on the top of the first sliding block 3. Then the first sliding block 3 will slide downwards. The first sliding block 3 will drive several soil-scraping plates 4 to move downwards. When the soil-scraping plates 4 have moved to the appropriate position, release the sliding column 16.
