DETAILED DESCRIPTION

[0041] In order to achieve the above-mentioned purpose and effect, the technical means and structures adopted by the present invention are described in detail with reference to the accompanying drawings for the features and functions of the preferred embodiments of the present invention.

[0042] like Figure 1-Figure 6 As shown, the present invention provides an agricultural seeder, comprising:

[0043] Front of car 1;

[0044] A sowing device, which is arranged at the rear side of the vehicle head 1 and is detachably connected to the vehicle head 1;

[0045] A center of gravity adjustment component is arranged 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 transverse adjustment rod 3, and the longitudinal adjustment rod 2 and the transverse adjustment rod 3 are both slidably connected with a weight block, and the longitudinal adjustment rod 2 and the transverse adjustment rod 3 are provided with one or more. The driver can adjust the position of the weight block according to the driving slope, so that the center of gravity of the front of the vehicle is close to the uphill side, reducing the risk of the device rolling over when driving on hills and mountains. When the front of the vehicle 1 falls into a pit while driving, causing the wheels on the driving side to be unable to fully contact the ground and making the front of the vehicle 1 unable to drive, the driver can adjust the position of the weight block so that the center of gravity of the front of the vehicle 1 is close to the wheels on the driving side, so that the wheels are fully in contact with the ground under the action of gravity, so that the front of the vehicle 1 can directly drive away by itself. At the same time, due to the complex topography of mountainous hills, the front of the vehicle 1 is at risk of dragging the ground when driving, and the center of gravity adjustment assembly can also protect the chassis of the front of the vehicle 1 to avoid damage to various components on the chassis of the front of the vehicle 1 when mopping the ground, further improving the adaptability of the front of the vehicle 1 to hills and mountains.

[0047] Preferably, a camera and an intelligent controller may be provided on the front of the vehicle 1, and the ground and topography may be observed by the camera, and the observation results may be analyzed by the intelligent controller, and the position of the weight may be automatically adjusted based on the analysis results.

[0048] Preferably, the longitudinal adjustment rod 2 and the transverse adjustment rod 3 are provided with a slide rail at one end away from the ground, and the slide rail is a multi-section slide rail. The weight is slidably connected to the slide rail, and the distance between two adjacent single-section slide rails is less than the length of the weight, so that the weight can slide continuously on the multi-section slide rail. Sprockets are provided at both ends of the slide rail, and chains are provided on the two sprockets. The chain is fixedly connected to the weight, and one of the sprockets is coaxially fixedly connected to the motor shaft of the driving motor, so that the sprocket is driven by the driving motor to rotate, and then the weight slides on the slide rail. At the same time, when the front of the vehicle 1 drags on the ground during driving and the longitudinal adjustment rod 2 or the transverse adjustment rod 3 is deformed by force, since the slide rail is a multi-section slide rail, the slide rail itself is less damaged, and the deformation of the longitudinal adjustment rod 2 or the transverse adjustment rod 3 can be simply adjusted to continue to be used.

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

[0050] Seeding equipment includes:

[0054] A second furrow opener, which is arranged at the rear side of the first furrow opener and is rotatably connected to the first connecting block 7;

[0055] A soil coverer, which is arranged at the rear side of the second furrow opener and is rotatably connected to the first connecting block 7;

[0056] A packer, which is arranged at the rear side of the soil cover and is rotatably connected to the first connecting block 7;

[0057] The seeding device is arranged on the horizontal rod 4. The seeding device is provided with a seeding tube for discharging seeds. The outlet of the seeding tube is located between the second furrow opener and the soil coverer.

[0058] When the vehicle head 1 drives the sowing equipment to move, 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 already opened furrow. The seed discharge device will discharge the seeds and discharge the seeds into the opened seed furrow through the seed discharge pipe. After the seeds enter the seed furrow, the soil covering device will push the soil accumulated on both sides back into the furrow and the soil will be compacted by the pressing wheel 18.

Two furrow opening discs 9 are symmetrically arranged at the lower end of the furrow opening rod 8, and the axes of the two furrow opening discs 9 form an angle along the circumference of the furrow opening rod 8. The two furrow opening discs 9 will enter the soil under the action of gravity, and discharge the soil to both sides under the action of the traction force of the vehicle head 1, forming a preliminary furrow.

[0060] Specifically, the longitudinal adjustment rod 2 can be extended to the first connecting block 7, so that the weight block can be slid to one side of the first connecting block 7, thereby increasing the gravity exerted on the ditching disc 9 and ensuring the ditching effect.

[0061] Specifically, the furrowing disc 9 is connected to the furrowing rod 8 through a telescopic rod, and the telescopic rod is rotatably connected to the furrowing rod 8, so that the telescopic rod can rotate along the circumference of the furrowing rod 8, thereby changing the angle between the two furrowing discs 9 through 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, and a retaining plate 25 is also provided on the trenching rod 8. The retaining plate 25 is located above the trenching disc 9. A scraping assembly is also provided on the retaining plate 25, and the scraping assembly is used to scrape off the soil attached to the trenching disc 9. The scraping assembly includes:

[0064] Four support plates 27, which are arranged on the mounting plate 26 and divided into two groups and arranged on both sides of the two ditching discs 9, and the support plates 27 are provided with scraping shafts 28 rotatably connected to the support plates 27;

[0065] A scraper plate 29, one end of which is disposed on the scraper shaft 28, and the other end of which is in contact with the ditching disc 9;

[0066] The torsion spring is arranged on the scraper shaft 28 so that the scraper shaft 28 is subjected to a force to rotate toward the ditching disc 9, thereby ensuring that the scraper plate 29 is in contact with the ditching disc 9.

[0067] In this embodiment, the second furrow opener includes a furrowing wheel 10 and a connecting curved rod 11. A second connecting block 12 is further provided between the first connecting block 7 and the furrowing rod 8. One end of the connecting curved 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 a seed furrow on the basis of the furrows opened by the two furrowing discs 9. The staff can also rotate the connecting curved rod 11 according to actual needs to adjust the depth of the furrowing wheel 10 into the soil, so as to open seed furrows of different depths.
