[0015] Step 1: The staff connects the support frame and the vehicle body through the connecting rod and the connecting auxiliary rod, and then the staff sits on the seat and controls the vehicle body to move the entire equipment to the position where highland barley is required to be planted;

[0016] Step 2: The staff further opens the box door through the box door handle. At this time, the controller controls the feeding motor to rotate the feeding main gear, thereby driving the feeding sub-gear to rotate, and then driving the two feeding plates to rotate, so that a gap is generated between the two feeding plates, so that it is convenient for the seeds to enter the bottom of the feeding port from the storage box, and then enter the inside of the feeding pipe. The staff further places the highland barley seeds in the storage box, and further closes the box door through the box door handle;

[0017] Step 3: The controller further controls the multiple furrow opener adjustment rods to start working, so that the multiple furrow opener adjustment shafts rotate, so that the furrow opener connecting plate moves downward, so that the covering plate adjustment rod moves downward, so that the furrow opener moves downward, and then the furrowing shovel moves downward, so that the multiple furrowing shovels are inserted into the soil according to the required depth. At this time, the whole equipment is balanced due to the action of the follower front wheel and the follower rear wheel. At this time, the covering plate support plate moves downward due to the action of the furrow opener connecting plate, so that the covering plate is closely attached to the ground in cooperation with the spring;

[0018] Step 4: At this time, the staff controls the vehicle body to move the entire equipment to the left, so that multiple trenching shovels dig multiple trenches in the soil. At the same time, the controller controls multiple speed adjustment motors to work, so that multiple speed adjustment main gears work, and then drive multiple speed adjustment sub-gears to work, thereby driving multiple speed adjustment sub-plates to rotate, so as to change the size of the through hole on the speed adjustment main board, thereby changing the amount of seeds falling, so as to achieve the purpose of changing the seeding density;

[0019] Step 5: At the same time, the controller controls the uniform sowing motor to work, thereby driving the uniform sowing main gear to rotate, thereby driving the uniform sowing sub-gear to rotate, thereby driving the uniform sowing plate to rotate at a uniform speed, so that the highland barley seeds on the uniform sowing plate can be transported to the bottom of the discharge port, and then transported to the soil, thereby achieving uniform sowing;

[0020] Step 6: At this time, the staff changes the speed by controlling the vehicle body. At the same time, the controller controls the gap between the speed adjustment sub-plate and the speed adjustment main plate and controls the rotation speed of the uniform seeding plate to change the seeding speed. At this time, since the entire equipment moves to the left, the covering plate can cover multiple trenches dug by trenching, thereby completing the seeding work.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This equipment can keep the left end of the support frame balanced by connecting the auxiliary rod and the follow-up front wheel, so as to ensure the stability of the operator and the safety of the operator. The follow-up rear wheel support rod, the follow-up rear wheel moving rod and the follow-up rear wheel spring of this equipment can make the follow-up rear wheel move up and down, so as to keep the right end of the support frame balanced, so as to keep the furrow opener and the covering plate balanced, so as to make the furrowing depth more uniform and consistent, and at the same time make the furrow depth controllable, so as to adapt to different areas, thereby expanding the use range of the equipment;

[0023] This equipment can drive two main feeding gears to rotate through two feeding motors, thereby driving two feeding sub-gears to rotate, and then driving two feeding plates to rotate, so as to control the amount of seeds entering the feeding tube, so that the amount of seeds on the speed regulating main board can be controlled, and at the same time reduce the pressure of the speed regulating main board, thereby increasing the service life of the equipment;

[0024] The equipment drives the uniform sowing main gear to rotate through the uniform sowing motor, thereby driving the uniform sowing sub-gear to rotate, thereby driving the uniform sowing plate to rotate, so that the seeds dropped from the speed regulating main board can reach the inside of the discharge port as the uniform sowing plate rotates, and thus reach the dug ditch. Furthermore, due to the uniform rotation of the uniform sowing plate, the amount of seeds entering the discharge port each time is the same, thereby achieving uniform sowing, thereby improving the sowing effect and efficiency.

[0025] The speed regulating motor drives the speed regulating main gear to rotate, which in turn drives the speed regulating sub-gear to rotate, thereby driving the speed regulating sub-plate to rotate, so that the amount of seeds reaching the top of the uniform sowing plate each time can be controlled, and the purpose of changing the seeding speed can be achieved by further changing the speed of the uniform sowing plate and the vehicle body;

[0026] Due to the gravity of the covering plate, the rotating shaft of the covering plate rotates around the rotating ring of the covering plate. At the same time, due to the action of the connecting rod and the spring, the covering plate is close to the ground. Therefore, when the whole equipment moves, the covering plate buries the trench dug by the trenching shovel, thereby completing the planting work and realizing automation.

[0058] Step 2: Further, the staff opens the box door 301 through the box door handle 302. At this time, the controller 203 controls the feeding motor 306 to rotate the feeding main gear 305, thereby driving the feeding sub-gear 304 to rotate, and then driving the two feeding plates 303 to rotate, so that a gap is generated between the two feeding plates 303, so that it is convenient for the seeds to enter the bottom of the feeding port 307 from the storage box 3, and then enter the inside of the feeding pipe 6. Further, the staff places the highland barley seeds inside the storage box 3, and further the staff closes the box door 301 through the box door handle 302;

[0059] Step 3: The controller 203 further controls the multiple furrow opener adjustment rods 504 to start working, so that the multiple furrow opener adjustment shafts 506 rotate, so that the furrow opener connecting plate 503 moves downward, so that the covering plate adjustment rod 806 moves downward, so that the furrow opener 5 moves downward, and then the furrowing shovel 501 moves downward, so that the multiple furrowing shovels 501 are inserted into the soil according to the required depth. At this time, the whole equipment is kept balanced due to the action of the follower front wheel 401 and the follower rear wheel 701. At this time, the covering plate support plate 808 moves downward due to the action of the furrow opener connecting plate 503, so that the covering plate 8 is closely attached to the ground in cooperation with the spring 802;

[0060] Step 4: At this time, the staff controls the vehicle body 1 to move the entire device to the left, so that the multiple trenching shovels 501 dig multiple trenches in the soil. At the same time, the controller 203 controls the multiple speed adjustment motors 612 to work, so that the multiple speed adjustment main gears 611 work, and then drive the multiple speed adjustment sub-gears 610 to work, thereby driving the multiple speed adjustment sub-plates 609 to rotate, so as to change the size of the through holes on the speed adjustment main plate 608, thereby changing the amount of seeds falling, so as to achieve the purpose of changing the seeding density;

[0061] Step 5: At the same time, the controller 203 controls the uniform sowing motor 606 to work, thereby driving the uniform sowing main gear 605 to rotate, thereby driving the uniform sowing sub-gear 604 to rotate, thereby driving the uniform sowing plate 607 to rotate at a constant speed, so that the highland barley seeds on the uniform sowing plate 607 can be transported to the bottom of the discharge port 603, and then transported to the soil, thereby achieving uniform sowing;

[0062] Step six: At this time, the staff changes the speed by controlling the vehicle body 1. At the same time, the controller 203 controls the gap between the speed regulating sub-plate 609 and the speed regulating main plate 608 and controls the rotation speed of the uniform seeding plate 607 to change the seeding speed. At this time, since the entire equipment moves to the left, the covering plate 8 can cover the trenches dug by multiple trenching shovels 501, thereby completing the seeding work.

[0063] The working process of the highland barley wide-width uniform sowing device with adjustable sowing speed of the present invention is as follows: before using the device, the staff connects the support frame 2 and the vehicle body 1 through the connecting rod 101 and the connecting sub-rod 204, and further the staff sits on the seat 202 and controls the vehicle body 1 to move the entire device to the position where highland barley is required to be sown, and further the staff opens the box door 301 through the box door handle 302, at which time the controller 203 controls the feeding motor 306 to rotate the feeding main gear 305, thereby driving the feeding sub-gear 304 to rotate, and then driving the two feeding plates 303 to rotate, so that the two feeding plates 303 are connected. A gap is created between the two feeding plates 303, and the staff then places the highland barley seeds in the storage box 3. The staff then closes the box door 301 through the box door handle 302. The seeds then reach the bottom of the feeding port 307 along the gap between the two feeding plates 303, and then enter the feeding tube 6. At this time, due to the action of the follower rear wheel 701, the follower rear wheel moving rod 702 moves upward, and at the same time cooperates with the follower rear wheel spring 703 to keep the right end of the support frame 2 balanced. Further, the controller 203 controls the plurality of furrow opener adjusting rods 504 to start working, so that the furrow opener adjusting shaft 506 rotates, thereby driving the furrow opener connecting plate 503 to move downward. The ditching shovels 501 are moved downward, thereby driving the ditching shovels 501 to move downward. At the same time, the covering plate adjustment plate 807 moves downward, thereby driving the covering plate support plate 808 to move downward, thereby driving the covering plate 8 to move downward. The staff further controls the vehicle body 1 to move the entire equipment, thereby causing the ditching shovels 501 to dig multiple trenches in the soil. At the same time, the staff controls the controller 203 to control the speed regulating motor 612 to work according to the needs, thereby driving the speed regulating main gear 611 to rotate, thereby driving the speed regulating sub-gear 610 to rotate, and then driving the speed regulating sub-plate 609 to rotate, thereby causing the The gap between the through holes of the speed regulating sub-plate 609 and the speed regulating main plate 608 is variable, so that the amount of seeds reaching the top of the uniform sowing plate 607 is variable, and further the seeds fall to the top of the uniform sowing plate 607 along the through holes on the speed regulating main plate 608, and further the controller 203 controls the uniform sowing motor 606 to work, thereby driving the uniform sowing main gear 605 to rotate, and then driving the uniform sowing sub-gear 604 to rotate, thereby driving the uniform sowing plate 607 to rotate, so as to transport the seeds above the uniform sowing plate 607 to the inside of the discharge port 603, and further transport them to the dug ditch. When it is necessary to change the sowing speed, the staff controls the vehicle body 1 to change the moving speed of the entire equipment.At the same time, the controller 203 controls the gap between the speed regulating main board 608 and the speed regulating sub-board 609, and at the same time, the uniform sowing motor 606 changes the rotation speed of the uniform sowing board 607, thereby achieving the purpose of changing the sowing speed. Further, the soil covering board 8 rotates downward due to inertia, so that the soil covering board 8 is closely attached to the ground. Further, as the vehicle body 1 continues to move, the dug trench can be covered with soil, thereby completing the sowing work.
