Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to an agricultural seeder. Background Technology

[0002] Mountainous and hilly areas account for about one-third of the country's arable land and crop planting area, making them important land resources. Currently, manual sowing is generally used in mountainous and hilly areas. Traditional manual sowing is simple but inefficient and wasteful of seeds. After the seedlings emerge, the spacing between plants and rows is often messy, requiring a lot of manpower for thinning and transplanting. The whole cycle is very time-consuming and labor-intensive. With the development of technology, people have begun to use mechanized sowing to speed up the process. However, the natural conditions in mountainous and hilly areas are poor, with complex terrain, fragmented and irregular plots, many slopes, terraces, and ridges. Existing sowing machinery cannot adapt well to the terrain of mountainous and hilly areas and is prone to accidents such as tipping over when moving. Utility Model Content

Detailed Implementation

[0041] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0042] like Figures 1-6 As shown, this utility model provides an agricultural seeder, comprising:

[0043] Locomotive 1;

[0044] The seeding equipment is located on the rear side of the vehicle head 1 and is detachably connected to the vehicle head 1.

[0045] The center of gravity adjustment component is located at the bottom of the front of the vehicle 1 and is used to change the center of gravity of the front of the vehicle 1.

[0046] Specifically, the center of gravity adjustment assembly includes a longitudinal adjustment rod 2 and a lateral adjustment rod 3. Both the longitudinal and lateral adjustment rods 2 and 3 are slidably connected to weights, and one or more weights are provided on each. The driver can adjust the position of the weights according to the slope, bringing the center of gravity of the vehicle's front closer to the uphill side, reducing the risk of rollover when driving on hilly terrain. When the vehicle's front 1 gets stuck in a ditch, preventing the drive-side wheels from making full contact with the ground and thus preventing further movement, the driver can adjust the position of the weights to bring the center of gravity of the vehicle's front 1 closer to the drive-side wheels, allowing the wheels to make full contact with the ground under gravity, enabling the vehicle's front 1 to move away on its own. Simultaneously, due to the complex terrain of hilly areas, there is a risk of the vehicle's front 1 dragging on the ground. The center of gravity adjustment assembly also protects the chassis of the vehicle's front 1, preventing damage to its components during dragging, further improving the vehicle's adaptability to hilly terrain.

[0047] Preferably, the front of the vehicle 1 can be equipped with a camera and an intelligent controller. The camera is used to observe the ground and terrain, and the intelligent controller is used to analyze the observation results and automatically adjust the position of the weight based on the analysis results.

[0048] Preferably, the ends of the longitudinal adjusting rod 2 and the lateral adjusting rod 3 away from the ground are equipped with slide rails. The slide rails are multi-section slide rails, and the weight is slidably connected to the slide rails. The distance between two adjacent single slide rail sections is less than the length of the weight, allowing the weight to slide continuously on the multi-section slide rails. Both ends of the slide rails are equipped with sprockets, and chains are mounted on the two sprockets. The chains are fixedly connected to the weight, and one of the sprockets is coaxially fixedly connected to the motor shaft of the drive motor. Thus, the drive motor drives the sprocket to rotate, thereby causing the weight to slide on the slide rails. At the same time, when the vehicle head 1 drags on the ground during driving, causing the longitudinal adjusting rod 2 or the lateral adjusting rod 3 to deform under force, the slide rails themselves suffer less damage because they are multi-section slide rails. They can be used again after simply adjusting the deformation of the longitudinal adjusting rod 2 or the lateral adjusting rod 3.

[0049] In another embodiment, a horizontal bar 4 is provided on the rear side of the front of the vehicle 1, and main connecting rods 5 are provided at both ends of the horizontal bar 4. One end of the main connecting rod 5 is detachably connected to the front of the vehicle 1, and the other end is detachably connected to the horizontal bar 4.

[0050] Seeding equipment includes:

[0051] Slider 6 is slidably connected to horizontal rod 4;

[0052] The first connecting block 7 is located at the bottom of the slider 6.

[0053] The first trencher is located at the bottom of the first connecting block 7;

[0054] The second trencher is located on the rear side of the first trencher and is rotatably connected to the first connecting block 7.

[0055] A soil coverer is located on the rear side of the second trencher and is rotatably connected to the first connecting block 7.

[0056] A compactor is located on the rear side of the backing device and is rotatably connected to the first connecting block 7.

[0057] The seed metering device is set on the horizontal bar 4. The seed metering device is equipped with a seed metering pipe for discharging seeds. The outlet of the seed metering pipe is located between the second furrow opener and the soil covering device.

[0058] When the locomotive 1 moves the seeding equipment, the first furrow opener will make a preliminary furrow on the ground, and the second furrow opener will further open a seed furrow on the basis of the furrow already opened. The seed discharging device will discharge the seeds and discharge the seeds into the opened seed furrow through the seed discharging pipe. After the seeds enter the seed furrow, the soil covering device will push the soil piled on both sides back into the furrow and compact it by the press roller 18.

[0059] In this embodiment, the first furrow opener includes a furrowing rod 8, which is positioned below the first connecting block 7. Two furrowing discs 9 are symmetrically arranged at the lower end of the furrowing rod 8, with their axes forming an angle along the circumference of the furrowing rod 8. The two furrowing discs 9 will enter the soil under gravity and, under the traction of the vehicle head 1, will discharge the soil to both sides, forming preliminary furrows.

[0060] Specifically, the longitudinal adjustment rod 2 can extend to the first connecting block 7, thereby allowing the weight to slide to one side of the first connecting block 7, increasing the gravity on the trenching disc 9 and ensuring the trenching effect.

[0061] Specifically, the furrowing disc 9 is connected to the furrowing rod 8 via a telescopic rod, and the telescopic rod is rotatably connected to the furrowing rod 8, so that the telescopic rod can rotate around the circumference of the furrowing rod 8. Thus, the included angle between the two furrowing discs 9 is changed by the rotation and extension of the telescopic rod, thereby changing the size of the furrow.

[0062] Preferably, the trenching disc 9 is rotatably connected to the telescopic rod 8, and a soil-blocking plate 25 is also provided on the trenching rod 8. The soil-blocking plate 25 is located above the trenching disc 9, and a soil-scraping assembly is also provided on the soil-blocking plate 25. The soil-scraping assembly is used to scrape off the soil adhering to the trenching disc 9. The soil-scraping assembly includes:

[0063] Mounting plate 26 is mounted on retaining plate 25;

[0064] Four support plates 27 are set on the mounting plate 26 and divided into two groups on both sides of the two trenching discs 9. The support plates 27 are equipped with scraping shafts 28 that are rotatably connected to the support plates 27.

[0065] The scraper blade 29 has one end mounted on the scraper shaft 28 and the other end in contact with the trenching disc 9.

[0066] A torsion spring is installed on the scraper shaft 28, so that the scraper shaft 28 is subjected to a force that rotates towards the trenching disc 9, ensuring that the scraper blade 29 is in contact with the trenching disc 9.

[0067] In this embodiment, the second furrow opener includes a furrowing wheel 10 and a connecting bent rod 11. A second connecting block 12 is also provided between the first connecting block 7 and the furrowing rod 8. One end of the connecting bent rod 11 is rotatably connected to the second connecting block 12, and the other end is connected to the center of the furrowing wheel 10. The furrowing wheel 10 will further open planting furrows based on the furrows opened by the two furrowing discs 9. The operator can also rotate the connecting bent rod 11 to adjust the soil penetration depth of the furrowing wheel 10 according to actual needs, thereby opening planting furrows of different depths.

[0068] In this embodiment, the backfilling device includes:

[0069] The third connecting block 13 is rotatably connected to the first connecting block 7 via the first connecting rod 14. The third connecting block 13 is provided with a through hole 15, which is used to fix the seeding pipe.

[0070] The soil covering rod 16 is fixedly connected to the end of the third connecting block 13 away from the first connecting block 7;

[0071] There are two covering wheels 17, symmetrically arranged at both ends of the covering rod 16. The bottoms of both covering wheels 17 are inclined towards the covering rod 16, and the distance between the bottoms of the two covering wheels 17 is adapted to the maximum distance between the two furrowing discs 9. Thus, the two covering wheels 17 push the soil discharged by the two furrowing discs 9 back into the furrow, covering the seeds.

[0072] Specifically, the covering rod 16 is connected to the covering wheel 17 via a covering shaft. The covering shaft and the covering rod 16 are rotatably connected, so that the bottom distance of the two covering wheels 17 can be adjusted according to the distance between the two trenching discs 9.

[0073] In this embodiment, the press includes a press wheel 18, a fourth connecting block 19, and a second connecting rod 20;

[0074] The press wheel 18 is mounted on the fourth connecting block 19. One end of the fourth connecting block 19 is rotatably connected to the third connecting block 13 via the second connecting rod 20, and the other end is rotatably connected to the press wheel 18.

[0075] In this embodiment, the seed metering device includes:

[0076] Fixing plate 21 is mounted on horizontal bar 4;

[0077] Support frame 22 is mounted on fixed plate 21;

[0078] Seed trough 23 is mounted on support frame 22, and a discharge port is provided at the bottom of seed trough 23;

[0079] The guide plate 24 is inclinedly set on the fixed plate 21. The upper end of the guide plate 24 is opposite to the discharge port. The upper end of the guide plate 24 is provided with a collection trough. One end of the collection trough is provided with a guide hole. One end of the guide hole is connected to the collection trough, and the other end is located at the bottom of the guide plate 24 and is connected to the inlet of the seeding pipe.

[0080] Workers can put seeds into the seed trough 23. The seeds in the seed trough 23 will gradually fall from the feed port and enter the collection trough on the guide plate 24. Then, they will slide into the seed discharge pipe through the guide hole at one end of the collection trough. The other end of the seed discharge pipe passes through the through hole 15 in the third connecting block 13 and extends to the top of the seed groove, so that the seeds can enter the seed groove.

[0081] Specifically, a vibrating motor is installed between the guide plate 24 and the fixed plate 21, and an electromagnetic valve is installed on the discharge port. The opening and closing of the discharge port is controlled by the electromagnetic valve, and the movement speed of the seeds in the seed trough 23 and the guide plate 24 is changed by changing the vibration frequency of the vibrating motor.

[0082] In another embodiment, multiple seeding devices are provided, and a seed metering device is provided between two adjacent seeding devices. The seed metering device has two guide holes and two seed metering pipes, which correspond to the two seeding devices respectively, so that one seed metering device can cooperate with two seeding devices to carry out seeding.
