After the synchronous operation of multiple vertical adjusting rods, high-efficiency carrot planting can be realized.

[0005] The utility model provides a carrot seeder, including the horizontal connecting rod that is set with the limit cap in both ends, interval setting is in the vertical adjusting rod on the horizontal connecting rod, setting is in the ridge forming assembly of the vertical adjusting rod front end and setting is in the seeding device of the vertical adjusting rod and located the ridge forming assembly rear side, the vertical adjusting rod with the horizontal connecting rod sliding connection;The vertical adjusting rod is equipped with the transverse communicating hole, the horizontal connecting rod passes through the communicating hole and is connected with several vertical adjusting rods, and several vertical adjusting rods are located in the limit cap on both sides. The upper side of the horizontal connecting rod is equipped with a strip-shaped adjusting groove, the number of adjusting grooves corresponds to the number of vertical adjusting rods, the vertical adjusting rod is equipped with a fixed screw, and the fixed screw is inserted into the adjusting groove after passing through the vertical adjusting rod.

[0006] The horizontal connecting rod and multiple vertical adjusting rods work together to form the frame structure of the seeder. The ridging component at the front end is used to create seeding troughs on the tilled ridges. The seeding device at the rear fills the seeding troughs with carrot seeds. The adjusting groove on the horizontal connecting rod cooperates with the fixing screw to make the distance between the vertical adjusting rods adjustable. When it is necessary to adjust the distance between the vertical adjusting rods, the fixing screw is loosened to disengage it from the adjusting groove, the position of the vertical adjusting rod is moved to the appropriate width, and the fixing screw is inserted back into the adjusting groove. Since the screw is threaded, it can be fixed or disengaged by turning the screw in the forward and reverse directions. A sliding nut can also be added inside the sliding groove to facilitate the adjustment of the distance and make the fixation more stable. The specific structure of the sliding connection between the nut and the adjusting groove can refer to the existing technology. The specific structure is not specifically limited here. Its essential purpose is to change the distance between the vertical adjusting rods through the sliding nut and to fix them stably.

[0007] In some embodiments, the transverse connecting rod includes a first transverse connecting rod, a second transverse connecting rod, and a third transverse connecting rod. All three connecting rods are slidably connected to the vertical adjusting rod. The first and second transverse connecting rods each have an adjusting groove. The fixing screw passes through the vertical adjusting rod and is inserted into the adjusting groove. The first, second, and third transverse connecting rods, combined with the vertical adjusting rod, form a grid structure, thereby stabilizing the entire seeder structure. The transverse connecting rods at both ends are used to install rollers for movement, allowing the seeder to move between rows. The second transverse connecting rod in the middle is adapted to the position of the first sand-covering device, providing support and ensuring its stable operation. When the spacing of the first transverse connecting rod at the front is adjusted, the second transverse connecting rod adjusts synchronously, keeping the vertical adjusting rod vertical so that all components on it can be aligned with the seeding trough.

[0008] In some embodiments, the first transverse connecting rod is disposed at the front end of the vertical adjusting rod and above the ridging assembly. The ridging assembly includes a support frame and a ridging roller. The support frame extends downward from the front end of the vertical adjusting rod, and the ridging roller is rotatably connected to the support frame. The ridging assembly is located at the front end of the entire seeder. The structure of the support frame supports the rolling operation of the ridging roller. During forward sowing, the ridging roller rotates counterclockwise to dig sowing troughs in the ground.

[0009] In some embodiments, the ridging roller is provided with a ridging protrusion circumferentially. The ridging protrusion has a trapezoidal cross-section, a top surface width of 1 cm, a bottom surface width of 3 cm, and a height of at least 15 cm. The two sides of the ridging protrusion are inclined. The size of the ridging protrusion is set according to the growth requirements of the carrot seeds, and the excavated planting trough is horizontal.

[0010] In some embodiments, the ridging roller is a grinding wheel with a radius of at least 15 cm, a maximum thickness of 3 cm, and a minimum width of 1 cm. Referring to grinding wheels in the prior art, this grinding wheel is thicker in the middle and thinner at the periphery, thereby excavating vertical sowing troughs. The specific dimensions of this grinding wheel are adapted to the actual growth needs of carrot seeds.

[0011] In some embodiments, the second lateral connecting rod is disposed at the tail end of the vertical adjusting rod, and the tail end of the vertical adjusting rod is further provided with a soil covering assembly. The soil covering assembly includes the support frame and a soil covering roller. The support frame extends downward from the tail end of the vertical adjusting rod, and the soil covering roller is rotatably connected between the support frames. The soil covering assembly is used to fill the seed trough after seeding. It is equipped with a conventional tire structure, and by traveling in a normal rear-to-front direction, the soil located on the rear or sides is compacted and refilled into the trough, thus achieving soil covering.

[0012] In some embodiments, the third transverse connecting rod is located between the sowing device and the ridging assembly. A first sand covering device is provided above the third transverse connecting rod and is connected to the vertical adjusting rod. The first sand covering device includes a receiving box, an elastic discharge pipe, and an electric switching valve. The bottom of the receiving box is connected to two of the elastic discharge pipes through the electric switching valve. The first sand covering device is used to initially cover the sowing trough with sand. The sand is guided into the sowing trough through the elastic discharge pipes on both sides. The electric switching valve is used to open and close the channel at timed intervals, thereby achieving precise feeding into the sowing trough. It should be understood that the specific opening and closing time interval of the electric switching valve is adjustable. Although the distance between the vertical adjusting rods is adjustable, the distance between the ridging assembly and the first sand covering device on the same vertical adjusting rod is constant. That is, the distance between the sowing trough opened by the ridging roller and the bidirectional fertilization device is constant and can be calculated. The operator can match the relationship between the fertilizer and sand falling time and the position of the sowing trough through multiple adjustments, thereby achieving precise feeding.

[0013] In some embodiments, a second sand covering device is provided between the sowing device and the second transverse connecting rod. The second sand covering device also includes the receiving box, the elastic discharge pipe, and the electric switch valve. The vertical adjusting rod is located between the two elastic discharge pipes, and the ends of the two elastic discharge pipes are attached together. According to the needs of carrot planting, after opening the sowing trough, it is necessary to first cover the trough with sand, and then cover it with sand again after sowing, so that the carrot seeds are evenly and loosely covered with sand on both sides, which is conducive to the root development and swelling of carrots. As can be seen from the above planting sequence, the first sand covering device is used for the initial sand covering, and the second sand covering device is used for the second sand covering. The discharge volume of the second sand covering device is greater than that of the first sand covering device. There is a through hole in the middle of the two elastic discharge pipes with their ends attached, which is used to reserve space for the movement of the vertical adjusting rod. The attachment of the ends allows the sand or soil to fall into the trough in a concentrated manner.

[0014] In some embodiments, the sowing device includes a housing, a seed metering device, and a drive motor. The seed metering device is disposed inside the housing, and the drive motor is disposed on the side of the housing and drives the seed metering device to rotate. The housing is disposed on the vertical adjusting rod. The main technical solution of the sowing device is that carrot seeds are filled from the top of the housing. After the seed metering device inside is driven to rotate by the drive motor, the seeds can be separated one by one and sown into the seed pit from the bottom of the housing. Each vertical adjusting rod is provided with an independent sowing device. The specific structure of the sowing device can be referred to the application document with application number CN202010056095.4, which describes the detailed technical solution of the sowing device. The carrot seeds of this application only need to be adapted to the seed trough and the rotation speed of the motor according to the actual situation, so they will not be described in detail here.

[0015] In some embodiments, a push rod is further included at the rear of the second sand-covering device. The push rod is U-shaped and its two ends are respectively connected to the two outermost vertical adjusting rods. A pull rod is provided on the push rod, and the pull rod is slidably connected to the push rod. The push rod is provided to facilitate the user to push the entire carrot planter. During the pushing process, the planter completes a series of actions including ridging, sand covering, sowing, sand covering again, and soil covering, thereby realizing carrot sowing. The pull rod on the push rod can be extended or retracted by manual pulling, thereby matching the changes in the spacing between the multiple vertical adjusting rods.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are:

[0017] This invention features several horizontal connecting rods and vertical adjusting rods, with the vertical adjusting rods sliding along the horizontal connecting rods. This allows for adjustable spacing between the vertical adjusting rods, adapting to different needs during actual sowing. The spacing between carrot planting troughs is adjusted, and the adjusting grooves and fixing screws on the horizontal connecting rods secure the sliding vertical adjusting rods, keeping their positions fixed during sowing. Each vertical adjusting rod is equipped with an independent ridging component, sand covering device, sowing device, and soil covering component, completing a series of actions in carrot planting: ridging, sand covering, sowing, re-sand covering, and soil covering. With multiple sets of vertical adjusting rods operating synchronously, high-efficiency carrot planting can be achieved. The multiple sand covering devices ensure that the seeds are surrounded by loose sand, improving the root growth environment of the carrots and preventing root deformation due to the absence of obstacles.

The ridge-opening component 3 at the front end is used to open the seeding troughs on the tilled ridges. The seeding device 4 located at the rear fills the seeding troughs with carrot seeds. The adjusting groove 15 on the horizontal connecting rod 1 cooperates with the fixing screw 16 to make the distance between the vertical adjusting rods 2 adjustable. When it is necessary to adjust the distance between the vertical adjusting rods 2, the fixing screw 16 is loosened to disengage it from the adjusting groove 15, the position of the vertical adjusting rod 2 is moved to the appropriate width, and the fixing screw 16 is inserted into the adjusting groove 15 again. Since the screw is threaded, it can be fixed or disengaged by turning the screw in the forward and reverse directions. A sliding nut can also be added inside the adjusting groove 15 to facilitate the adjustment of the distance and make the fixation more stable. The specific structure of the sliding connection between the nut and the adjusting groove 15 can refer to the existing technology. The specific structure is not specifically limited here. Its essential purpose is to drive the change of the distance between the vertical adjusting rods 2 through the sliding nut and to fix them stably.

[0051] The transverse connecting rod 1 includes a first transverse connecting rod 11, a second transverse connecting rod 12, and a third transverse connecting rod 13. The first transverse connecting rod 11, the second transverse connecting rod 12, and the third transverse connecting rod 13 are all slidably connected to the vertical adjusting rod 2. The first transverse connecting rod 11 and the second transverse connecting rod 12 are each provided with an adjusting groove 15. The fixing screw 16 passes through the vertical adjusting rod 2 and is inserted into the adjusting groove 15. The first transverse connecting rod 11, the second transverse connecting rod 12, and the third transverse connecting rod 13, together with the vertical adjusting rod 2, form a grid structure, thereby fixing and stabilizing the entire seeder structure. The transverse connecting rods 1 at both ends are used to install rollers for travel, allowing the seeder to move between rows.

As can be seen from the above planting sequence, the first sand covering device 7 is used for the initial sand covering, and the second sand covering device 8 is used for the second sand covering. The discharge volume of the second sand covering device 8 is greater than that of the first sand covering device 7. There is a through hole in the middle of the two elastic discharge pipes 72 with their ends attached, which is used to reserve space for the movement of the vertical adjusting rod 2.

[0057] Optionally, according to some embodiments of this utility model, the first transverse connecting rod 11 is disposed at the front end of the vertical adjusting rod 2 and above the ridging assembly 3. The ridging assembly 3 includes a support frame 5 and a ridging roller 31. The support frame 5 extends downward from the front end of the vertical adjusting rod 2, and the ridging roller 31 is rotatably connected to the support frame 5.

During the forward sowing process, the ridging roller 31 rotates counterclockwise to dig sowing troughs on the ground.

[0058] The ridging roller 31 has a circumferential ridging protrusion 311. The cross-section of the ridging protrusion 311 is trapezoidal. The top surface width of the ridging protrusion 311 is 1 cm, the bottom surface width is 3 cm, and the height is at least 15 cm. The two sides of the ridging protrusion 311 are inclined. The size of the ridging protrusion 311 is set according to the growth requirements of carrot seeds, and the excavated planting trough is horizontal.

[0059] The ridging roller 31 is a grinding wheel with a radius of at least 15cm, a maximum thickness of 3cm, and a minimum width of 1cm. Referring to existing grinding wheels, this wheel is thicker in the middle and thinner at the periphery, thus creating vertical sowing troughs.

The electric switch valve 73 is used to open and close the channel at timed intervals, thereby achieving precise feeding into the seeding trough. It should be understood that the specific opening and closing time interval of the electric switch valve 73 is adjustable. Although the distance between the vertical adjustment rods 2 is adjustable, the distance between the ridging component 3 and the first sand covering device 7 on the same vertical adjustment rod 2 is constant. That is, the distance between the seeding trough opened by the ridging roller 31 and the bidirectional fertilization device is constant and can be calculated. The staff can match the relationship between the fertilizer and sand falling time and the seeding trough position through multiple adjustments, thereby achieving precise feeding.

As can be seen from the above planting sequence, the first sand covering device 7 is used for the initial sand covering, and the second sand covering device 8 is used for the second sand covering. The discharge volume of the second sand covering device 8 is greater than that of the first sand covering device 7. There is a through hole in the middle of the two elastic discharge pipes 72 with their ends attached, which is used to reserve space for the movement of the vertical adjusting rod 2. The attachment of the ends allows the sand or soil to fall into the trough in a concentrated manner.

[0068] The sowing device 4 includes a shell, a seed metering device, and a drive motor. The seed metering device is housed inside the shell, and the drive motor is located on the side of the shell and drives the seed metering device to rotate. The shell is mounted on the vertical adjusting rod 2. The main technical solution of the sowing device 4 is that carrot seeds are filled from the top of the shell. After the drive motor drives the internal seed metering device to rotate, the seeds can be separated one by one and sown into the seed pit from the bottom of the shell. Each vertical adjusting rod 2 is equipped with an independent sowing device 4. The specific structure of the sowing device 4 can be found in the application document with application number CN202010056095.4, which describes the detailed technical solution of the sowing device 4. The carrot seeds of this application only need to be adapted to the seed trough and the rotation speed of the motor according to the actual situation, so they will not be described in detail here.

[0069] It also includes a push rod 9 located behind the second sand-covering device 8. The push rod 9 is U-shaped and its two ends are respectively connected to the two outermost vertical adjusting rods 2. A pull rod 10 is provided on the push rod 9, and the pull rod 10 is slidably connected to the push rod 9. The push rod 9 is provided to facilitate the user to push the entire carrot planter. During the pushing process, the planter completes the entire series of actions of ridging, sand covering, sowing, sand covering again, and soil covering to realize carrot sowing. The pull rod 10 on the push rod 9 can be extended or retracted by manual pulling, thereby matching the changes in the spacing between the multiple vertical adjusting rods 2.

[0070] Reference Figure 2 , Figure 2 This is a schematic diagram of the specific structure of the ridging component and the first sand covering device in Embodiment 1 of this utility model.

[0071] Optionally, according to some embodiments of this utility model, the first transverse connecting rod 11 is disposed at the front end of the vertical adjusting rod 2 and above the ridging assembly 3. The ridging assembly 3 includes a support frame 5 and a ridging roller 31. The support frame 5 extends downward from the front end of the vertical adjusting rod 2, and the ridging roller 31 is rotatably connected to the support frame 5. The ridging assembly 3 is located at the front end of the entire seeder. The structure of the support frame 5 supports the rolling operation of the ridging roller 31. During the forward sowing process, the ridging roller 31 rotates counterclockwise to dig sowing troughs on the ground.

[0072] The ridging roller 31 has a circumferential ridging protrusion 311. The cross-section of the ridging protrusion 311 is trapezoidal. The top surface width of the ridging protrusion 311 is 1 cm, the bottom surface width is 3 cm, and the height is at least 15 cm. The two sides of the ridging protrusion 311 are inclined. The size of the ridging protrusion 311 is set according to the growth requirements of carrot seeds, and the excavated planting trough is horizontal.

[0073] The third transverse connecting rod 13 is located between the sowing device 4 and the ridging component 3. A first sand covering device 7 is provided above the third transverse connecting rod 13 and is connected to the vertical adjusting rod 2. The first sand covering device 7 includes a receiving box 71, an elastic discharge pipe 72 and an electric switch valve 73. The bottom of the receiving box 71 is connected to two elastic discharge pipes 72 through the electric switch valve 73. The first sand covering device 7 is used to initially cover the prepared seeding trough with sand. The sand is guided into the seeding trough through the elastic discharge pipes 72 on both sides. The electric switch valve 73 is used to open and close the channel at timed intervals, thereby achieving precise feeding into the seeding trough. It should be understood that the specific opening and closing time interval of the electric switch valve 73 is adjustable. Although the distance between the vertical adjustment rods 2 is adjustable, the distance between the ridging component 3 and the first sand covering device 7 on the same vertical adjustment rod 2 is constant. That is, the distance between the seeding trough opened by the ridging roller 31 and the bidirectional fertilization device is constant and can be calculated. The staff can match the relationship between the fertilizer and sand falling time and the seeding trough position through multiple adjustments, thereby achieving precise feeding.

[0075] The difference between this embodiment and Embodiment 1 is that:

[0076] Reference Figure 3 , Figure 3 This is a schematic diagram of the specific structure of the ridging component and the first sand covering device in Embodiment 2 of this utility model.

[0077] The ridging roller 31 is a grinding wheel with a radius of at least 15cm, a maximum thickness of 3cm, and a minimum width of 1cm. Referring to existing grinding wheels, this wheel is thicker in the middle and thinner at the periphery, thus creating vertical sowing troughs. The specific dimensions of this grinding wheel are adapted to the actual growth needs of carrot seeds.
