Description
Technical Field
[0001] This invention patent relates to the technical field of furrow sowing, and more specifically, to an automatic furrow sowing method. Background Technology
[0002] With the development of automation technology, agricultural production now largely adopts mechanized and automated operations. Currently, when sowing seeds in a field, it is generally necessary to first dig furrows in the field and then place the seeds in the furrows.
[0003] In existing technologies, trenching and sowing are usually handled separately. First, trenching is carried out uniformly, and then sowing is carried out. This makes the entire trenching and sowing operation more complicated and less efficient. Summary of the Invention
[0004] The purpose of this invention is to provide an automatic furrowing and sowing method, which aims to solve the problem of low efficiency in furrowing and sowing in the prior art.
[0005] The present invention is implemented as follows: an automatic furrowing and sowing method is provided, comprising a vehicle body that moves on the field; the vehicle body is equipped with a furrow opener that moves up and down, and a seed drop tube is provided behind the furrow opener, the seed drop tube being arranged separately from the furrow opener, and the seed drop tube having a drop channel for seeds to fall; the vehicle body is equipped with a seed storage box, the seed storage box having a seed storage cavity for storing seeds, and the bottom of the seed storage cavity having a bottom opening;
[0006] The lower part of the seed storage chamber is provided with a transfer structure that allows the seeds in the seed storage chamber to fall one by one through the bottom opening; the bottom opening is connected to the top of the seed dropping tube through a pipe.
[0007] Once the vehicle travels to the designated position in the field, the furrow opener moves downwards a set distance until it is inserted into the soil. As the vehicle travels along the designated trajectory in the field, the furrow opener creates a trench in the pad, forming excavated ridges on both sides of the trench. The transfer structure then transfers the seeds from the seed storage chamber one by one through the bottom opening into the pipe and into the trench via the drop channel.
[0008] Furthermore, front rollers are provided on both sides of the front end of the vehicle body, with the two front rollers spaced apart. Rear rollers are provided on both sides of the rear end of the vehicle body, with the two rear rollers spaced apart. By controlling the differential rolling between the two front rollers and the differential rolling between the two rear rollers, the vehicle body can turn or turn around on the field.
[0009] Furthermore, the furrow opener and seed-dropping tube are arranged in the middle of the vehicle body. As the vehicle body travels in the field along a set trajectory, the rear roller compacts the soil ridges on both sides of the furrow, pushing the soil of the ridges into the furrow and burying the seeds in the furrow.
[0010] Furthermore, the outer surface of the front roller is provided with multiple protruding teeth. When the vehicle body travels on the field, the protruding teeth rotate synchronously with the front roller and are embedded in the soil.
[0011] Furthermore, along the direction in which the vehicle travels in the field, the ditch opener is flat and sheet-like; the front end and rear end of the ditch opener each have a ditching section, and the thickness of the ditching section gradually decreases along the direction from the middle to the end of the ditch opener; as the vehicle travels in the field according to the set trajectory, the ditching section squeezes and lifts the soil in the soil to both sides, so as to form the trench in the field, and the lifted soil forms the ridge on both sides of the trench.
[0012] Furthermore, the end of the trenching part is pointed, forming a trenching blade that extends vertically, and the trenching blade is inclined towards the center of the trencher along the direction from top to bottom; when the vehicle moves in the field according to the set trajectory, after the trenching blade cuts the soil, the trenching part squeezes and lifts the cut soil to both sides.
[0013] Furthermore, the two sides of the trenching part are formed with soil squeezing surfaces. The inner end of the soil squeezing surface extends to the middle of the trencher, and the outer end of the soil squeezing surface extends to the end of the trencher. The outer ends of the two soil squeezing surfaces converge into one to form the trenching edge.
[0014] Along the direction from the inner end to the outer end of the squeezing surface, the squeezing surface is arranged inward at an inward angle; as the vehicle moves in the field along a set trajectory, after the soil is cut by the ditching blade, the two squeezing surfaces of the ditching part squeeze and lift the cut soil to both sides.
[0015] Furthermore, the trencher has a central section in the middle, and the two sides of the central section have longitudinally arranged intermediate surfaces. The inner end of the soil-displacing surface is connected to the end of the intermediate surface. As the vehicle moves in the field along a set trajectory, the two intermediate surfaces press against the soil on both sides of the trench to keep the trench in shape.
[0016] Furthermore, the transfer structure includes a laterally arranged rotating shaft, the rotating shaft having a transfer section passing through the lower part of the seed storage chamber, the transfer section being provided with a receiving groove for accommodating a set number of seeds;
[0017] When seeds in the seed storage chamber need to be dropped one by one through the bottom opening, the rotating shaft rotates until the receiving groove faces upward and is connected to the seed storage chamber vertically. After the seeds in the seed storage chamber fall into the receiving groove, the rotating shaft continues to rotate until the receiving groove faces downward and is connected to the bottom opening. The seeds in the receiving groove fall through the bottom opening. The rotating shaft continues to rotate, continuously dropping the seeds in the seed storage chamber one by one through the bottom opening.
[0018] Furthermore, the bottom of the seed-dropping tube is connected to a flexible guide cylinder, which has a guide channel and multiple ventilation channels arranged at intervals along the circumference of the guide cylinder. The upper end of each ventilation channel extends to the top of the guide cylinder and communicates with an air blowing device, while the lower end extends to the lower part of the guide cylinder and penetrates the inner wall of the guide cylinder inward, forming air blowing holes arranged at an angle from top to bottom. The bottom of the guide cylinder is provided with multiple flexible sheets arranged at intervals around the circumference of the guide cylinder.
[0019] When the seeds enter the guide channel of the guide cylinder from the falling channel, the air blowing device blows air into the air passage. The airflow is discharged through multiple air holes, guiding the falling trajectory of the seeds in the guide channel. Under the blowing of the airflow, multiple flexible sheets are in an outward expanding state, limiting external interference with the falling trajectory of the seeds.
[0020] Compared with existing technologies , The automatic furrowing and sowing method provided by this invention involves using a furrow opener to dig furrows in the field while the vehicle is moving through it. Then, a transfer structure is used to transfer the seeds from the seed storage chamber one by one, and the seeds are dropped into the furrows through a seed drop tube. This achieves simultaneous operation of furrowing and sowing. Furthermore, the furrow opener and the seed drop tube are set separately, so that the seed drop tube will not be interfered with when the vehicle is turning, thus ensuring the smoothness of the seeds dropping from the seed drop tube.

[0029] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.
[0030] An automatic furrowing and sowing method is provided, including a vehicle body 100 that moves on the field; a furrow opener 400 that moves up and down is provided in the vehicle body 100, and a seed drop tube 300 is provided behind the furrow opener 400. The seed drop tube 300 is arranged separately from the furrow opener 400 and has a drop channel for seeds to fall; a seed storage box 101 is provided in the vehicle body 100, and the seed storage box 101 has a seed storage cavity for storing seeds, and the bottom of the seed storage cavity has a bottom opening 103; a large number of seeds can be placed in the seed storage box 101.
[0031] The lower part of the seed storage chamber is provided with a transfer structure that allows the seeds in the seed storage chamber to fall one by one through the bottom opening 103; the bottom opening 103 is connected to the top of the seed dropping tube 300 through a pipe; of course, according to actual needs, multiple seeds in the seed storage chamber can also be transferred to the bottom opening 103, depending on the actual situation.
[0032] When the vehicle body 100 travels to the set position in the field, the furrow opener 400 moves downward a set distance until it is inserted into the soil of the field. As the vehicle body 100 travels in the field along the set trajectory, the furrow opener 400 opens a trench in the pad, and the sides of the trench form excavated ridges. The transfer structure drops the seeds in the seed storage chamber one by one into the pipe through the bottom opening 103 and into the trench through the falling channel.
[0033] The automatic furrowing and sowing method described above involves the vehicle body 100 moving through the field, using the furrow opener 400 to dig furrows in the field, and then using the transfer structure to transfer the seeds in the seed storage chamber one by one, which are then dropped into the furrows through the seed drop tube 300. This achieves simultaneous operation of furrowing and sowing. Furthermore, the furrow opener 400 and the seed drop tube 300 are set separately, so that the vehicle body 100 will not interfere with the seed drop tube 300 when turning, thus ensuring the smoothness of the seeds falling from the seed drop tube 300.
[0034] In this embodiment, front rollers 201 are respectively provided on both sides of the front end of the vehicle body 100, and the two front rollers 201 are arranged at intervals. Rear rollers 202 are respectively provided on both sides of the rear end of the vehicle body 100, and the two rear rollers 202 are arranged at intervals. By controlling the differential rolling between the two front rollers 201 and the differential rolling between the two rear rollers 202, the vehicle body 100 can turn or turn around on the field.
[0035] In this way, when sowing, there is no need for manual operation of the vehicle body 100 by holding the handle, no need for manual adjustment of the direction of the vehicle body 100 by holding the handle, and no need for manual force to change the direction of the entire vehicle body 100 when changing rows, which greatly improves sowing efficiency and reduces labor intensity.
[0036] The furrow opener 400 and the seed-dropping tube 300 are arranged in the middle of the vehicle body 100. As the vehicle body 100 travels in the field along a set trajectory, the rear roller 202 compacts the soil ridges on both sides of the furrow, pushing the soil from the ridges into the furrow and burying the seeds in the furrow. The automatic burying of the furrow by the rear roller 202 greatly improves the sowing efficiency.
[0037] The outer surface of the front roller 201 is provided with multiple protruding teeth 203. When the vehicle body 100 travels on the field, the protruding teeth 203 rotate synchronously with the front roller 201 and are embedded in the soil. This improves the travel efficiency of the vehicle body 100 on the field.
[0038] In this embodiment, along the direction of travel of the vehicle body 100 in the field, the ditch opener 400 is flat and sheet-like; the front end and rear end of the ditch opener 400 are respectively provided with ditching sections, and the thickness of the ditching sections gradually decreases along the direction from the middle to the end of the ditch opener 400; as the vehicle body 100 travels in the field according to the set trajectory, the ditching sections squeeze and lift the soil in the soil to both sides, so as to form the trench in the field, and the lifted soil forms the ridge on both sides of the trench.
[0039] The furrow opener 400 is simple to operate, sturdy and durable, and can achieve fully automated lifting and lowering, which can effectively improve sowing efficiency, reduce the number of people operating the equipment, and reduce labor intensity.
[0040] Secondly, the furrow opener 400 adopts a boat-shaped furrow opener 400, with the thickness of the furrow section gradually decreasing and the width of the furrow being smaller than that of those on the market, reducing the error in the sowing spacing; when the vehicle body 100 needs to reverse, the furrow opener 400 will not raise the soil, and the furrow opener 400 and the seed drop tube 300 are designed separately to avoid soil clogging the seed drop tube 300.
[0041] In this embodiment, the end of the trenching part is pointed, forming a trenching blade 402 that extends vertically. Along the direction from top to bottom, the trenching blade 402 is inclined toward the middle of the trencher 400. When the vehicle body 100 travels in the field according to the set trajectory, after the trenching blade 402 cuts the soil, the trenching part squeezes and lifts the cut soil to both sides.
[0042] This greatly improves the ditching operation of the ditcher 400 in the field, and the ditching blade 402 can cut the soil more easily.
[0043] In this embodiment, soil squeezing surfaces 401 are formed on both sides of the trenching part. The inner end of the soil squeezing surface 401 extends to the middle of the trencher 400, and the outer end of the soil squeezing surface 401 extends to the end of the trencher 400. The outer ends of the two soil squeezing surfaces 401 are joined together to form a trenching blade edge 402.
[0044] Along the direction from the inner end to the outer end of the squeezing surface 401, the squeezing surface 401 is arranged inward at an inward angle; as the vehicle body 100 travels in the field according to the set trajectory, after the soil is cut by the ditching blade 402, the two squeezing surfaces 401 of the ditching part squeeze and lift the cut soil to both sides.
[0045] By using two extrusion surfaces 401, the soil cut by the trenching edge 402 can be squeezed outward, making trench excavation more convenient.
[0046] The furrow opener 400 has a middle section 403 in the middle, and the two sides of the middle section 403 have longitudinally arranged middle surfaces. The inner end of the soil squeezing surface 401 is connected to the end of the middle surface. When the vehicle body 100 moves in the field according to the set trajectory, the two middle surfaces press against the soil on both sides of the furrow to keep the furrow in shape. In this way, it can avoid the soil from re-burying the furrow after it is dug and before sowing, and can better maintain the shape of the furrow to facilitate subsequent sowing.
[0047] In this embodiment, the transfer structure includes a horizontally arranged rotating shaft 102, the rotating shaft 102 having a transfer section passing through the lower part of the seed storage cavity, and the transfer section having a receiving groove for holding a set number of seeds.
[0048] When the seeds in the seed storage chamber need to be dropped one by one through the bottom opening 103, the rotating shaft 102 rotates until the receiving groove faces upward and is connected to the seed storage chamber vertically. After the seeds in the seed storage chamber fall into the receiving groove, the rotating shaft 102 continues to rotate until the receiving groove faces downward and is connected to the bottom opening 103. The seeds in the receiving groove fall through the bottom opening 103. The rotating shaft 102 continues to rotate, continuously dropping the seeds in the seed storage chamber one by one through the bottom opening 103.
[0049] In this way, by controlling the rotation speed of the rotating shaft 102, the sowing density can be achieved, and by setting the size of the receiving trough, the number of seeds transferred in a single operation can be determined.
[0050] In this embodiment, a flexible guide tube 500 is connected to the bottom of the seed-dropping tube 300. The guide tube 500 has a guide channel 502 and multiple ventilation channels 501. The multiple ventilation channels 501 are arranged at intervals along the circumference of the guide tube 500. The upper end of the ventilation channel 501 extends to the top of the guide tube 500 and communicates with the air blowing device. The lower end of the ventilation channel 501 extends to the lower part of the guide tube 500 and penetrates the inner sidewall of the guide tube 500 inward, forming air blowing holes arranged at an angle from top to bottom. The bottom of the guide tube 500 is provided with multiple flexible pieces 503, which are arranged at intervals around the circumference of the guide tube 500.
[0051] When the seeds from the falling channel enter the guide channel 502 of the guide cylinder 500, the air blowing device blows air into the air passage 501. The airflow is discharged through multiple air holes, guiding the falling trajectory of the seeds in the guide channel 502. Under the blowing of the airflow, multiple flexible sheets 503 are in an outward expanding state, limiting external interference with the falling trajectory of the seeds.
[0052] As the vehicle 100 travels through the field, the seeds fall through the seed drop tube 300 and enter the ditch. To prevent external wind and other factors from affecting the seed's trajectory and causing it to deviate from its set position in the ditch, multiple air pipes are used for air guidance, and multiple flexible sheets 503 are used for outward expansion and blocking, thus ensuring the seed's trajectory.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
