Description

Technical Field

[0001] This utility model relates to the field of soybean planter technology, specifically a soybean planter with adjustable row spacing. Background Technology

[0002] Soybeans are one of the grains frequently used by growers. Soybeans are usually sown by large planters. For small areas that are difficult for planters to access, a planter is usually needed to sow soybeans. Therefore, a soybean planter is required.

[0003] A Chinese patent with authorization announcement number CN221615543U discloses a soybean planter, including a storage box. Supports are fixed to both sides of the storage box. A rotating rod is rotatably connected through one side of each support. A first bevel gear is fixed to one end of the rotating rod. A second bevel gear is meshed with the side of the first bevel gear. A rotating shaft is fixed to the top center of the second bevel gear. A third bevel gear is fixed to one end of the rotating shaft. A fourth bevel gear is meshed with the side of the third bevel gear. A rotating shaft is fixed to the center of the fourth bevel gear. A drive wheel is fixed to one end of the rotating shaft. A connecting belt is slidably connected to the surface of the drive wheel in a wound manner. A driven wheel is slidably connected to one end of the connecting belt in a wound manner. This invention, by setting up a auger shaft and a stirring rod, avoids soybean seed accumulation affecting discharge efficiency, prevents seeds from falling in a concentrated manner, and ensures smooth soybean transportation.

[0004] However, the above-mentioned planter still has some problems. In practical applications, when planting soybeans, the row spacing cannot be adjusted. Different varieties require different row spacings, otherwise it will affect light and ventilation, thereby affecting the normal growth of soybeans and leading to a decrease in yield. Therefore, an adjustable row spacing soybean planter is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems mentioned in the background art, this utility model proposes a soybean planter with adjustable row spacing.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The adjustable row spacing soybean planter of this utility model includes a support frame. A support rod is fixedly connected between the two inner sides of the top of the support frame. Five sliders are equidistantly slidably installed on the outer sides of the support rods and the support frame. A rack is installed on one inner wall of the support frame. A mounting frame is installed on the top side of each slider. A rotating shaft is movably installed at the bottom of one end of the mounting frame, extending to the bottom of the slider. A worm gear and a gear are respectively installed at the top and bottom of the rotating shaft, and the gears mesh with the rack. A servo motor is installed on one inner wall of the mounting frame. A rotating shaft is installed at the output end of the servo motor. One end of the rotating shaft is rotatably installed on the other inner wall of the mounting frame. On the wall, worm gears are installed on the outer side of the rotating shaft, and the worm wheel meshes with the worm. A servo motor drives the rotating shaft to rotate the worm, which in turn drives the worm wheel and gear to rotate. Because the gear and rack mesh with each other, the slider can move precisely on the support rod, thereby flexibly adjusting the row spacing between the soybean tubes. The optimal row spacing can be quickly adjusted according to the planting requirements of different soybean varieties and soil conditions, improving the yield and quality of soybeans. Moreover, the worm wheel and worm gear structure has a self-locking function. When the slider is adjusted to the appropriate position, the worm wheel and worm gear work together to effectively lock the position of the slider, preventing the slider from moving due to vibration or other factors during planting, ensuring that the row spacing between the soybean tubes remains stable, and guaranteeing the uniformity and consistency of soybean planting.

[0007] Preferably, an mounting block is installed on the bottom side of the slider, and a storage bucket is installed at one end of the mounting block. A soybean outlet pipe is connected to the bottom side of the storage bucket. A funnel is installed on the inner wall of the bottom of the storage bucket above the soybean outlet pipe. A feed pipe is installed at the bottom of the funnel. A protective cover is installed on one side of the soybean outlet pipe, and a small motor is installed inside the protective cover. A sphere is installed inside the soybean outlet pipe at the output end of the small motor. Several storage holes are equidistantly opened on the outer side of the sphere. The feed pipe is located directly above one of the storage holes. The funnel is installed on the inner wall of the bottom of the storage bucket and above the soybean outlet pipe, which can guide the soybeans to the feed pipe, allowing them to smoothly enter the soybean outlet pipe. The small motor drives the sphere to rotate inside the soybean outlet pipe. During rotation, the several storage holes equidistantly opened on the sphere align sequentially with the feed pipe, achieving quantitative and uniform soybean output. This soybean output method avoids problems such as uneven output and blockage that may occur in traditional soybean output methods, ensuring a consistent sowing amount for each soybean plant, which is beneficial to soybean growth and development and yield improvement.

[0008] Preferably, a cover plate is installed on the top side of the storage bucket via a hinge, and a handle is installed on the top edge of the cover plate. A plow is installed on the bottom side of the slider. The plow is made of metal. The handle design allows the operator to easily open and close the cover plate, making it convenient to put soybeans into the storage bucket, improving the convenience and efficiency of feeding. The plow can turn over the soil during the movement of the planter to form a suitable planting furrow, so that the soybeans falling from the soybean outlet pipe can smoothly enter the soil, ensuring the planting quality of soybeans.

[0009] Preferably, a connecting frame is installed at the top edge of the support frame, and two connecting plates are symmetrically installed on one side of the top of the connecting frame. Each connecting plate has an installation hole inside, which facilitates the connection of the planter to external power equipment, making it convenient to move and operate between different plots.

[0010] Preferably, two mounting brackets are symmetrically installed at both ends of the bottom side of the support frame, and wheels are installed between the two sides of the mounting brackets through a pin engagement, which facilitates the movement of the planter.

[0011] Preferably, a controller is installed on one side of the support frame. The controller is electrically connected to the electrical components inside the planter and is used to control the operation of the electrical components inside the planter. The operator can conveniently adjust the speed and direction of the servo motor through the controller, control the start and stop of the small motor and its rotation speed, thereby achieving precise adjustment of the row spacing and bean output of the bean outlet tube.

[0012] The advantages of this utility model are:

[0013] 1. This utility model sends a command to the servo motor through the controller. The servo motor starts and its output shaft drives the worm gear to rotate. Since the worm wheel meshes with the worm, the worm wheel drives the rotating shaft, which in turn causes the gear to rotate. Since the gear meshes with the rack on the inner wall of the support frame, it drives the slider to slide along the support rod, thereby realizing the adjustment of the spacing between the mounting frame and the bean outlet tube. Moreover, the self-locking function of the worm wheel and worm gear ensures that the slider will not shift due to vibration after it is fixed, thus ensuring accurate and stable row spacing.

[0014] 2. The present invention then opens the handle of the cover plate, puts the soybeans into the storage bucket, guides the soybeans to the feed pipe through the funnel, starts the small motor, and drives the ball to rotate in the soybean outlet pipe through its output end. The storage holes on the ball are aligned with the feed pipe in sequence, and after quantitatively receiving the soybeans, they are transferred to the soybean outlet pipe outlet to achieve uniform sowing and avoid blockage and uneven sowing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4As shown, an adjustable row spacing soybean planter includes a support frame 1. Support rods 2 are fixedly connected between the two inner sides of the top of the support frame 1. Five sliders 201 are equidistantly slidably mounted on the outer sides of the support rods 2 and the support frame 1. A rack 202 is installed on one inner wall of the support frame 1. Mounting frames 203 are mounted on the top side of each slider 201. One end of the mounting frame 203 extends movably through to the bottom side of the slider 201 and is rotatably mounted with a rotating shaft 204. The top and bottom ends of the rotating shaft 204 are respectively equipped with a worm gear 205 and a gear 206, and the gear 206 meshes with the rack 202. A servo motor 207 is installed on one inner wall of the mounting frame 203. A rotating shaft 208 is installed at the output end of the servo motor 207. One end of the rotating shaft 208 is rotatably installed on the other inner wall of the mounting frame 203. Worms 209 are installed on the outer side of the rotating shaft 208, and the worm gear 205 meshes with the worm 209.

[0024] A controller 8 is installed on one side of the support frame 1. The controller 8 is electrically connected to the electrical components inside the planter and is used to control the operation of the electrical components inside the planter. In practical applications, when planting soybeans, the row spacing cannot be adjusted. Different varieties require different row spacings; otherwise, it will affect light and ventilation, thus affecting the normal growth of soybeans and leading to a decrease in yield. Based on the soybean variety and soil conditions, the operator sends a command to the servo motor 207 through the controller 8. The servo motor 207 starts, and its output shaft 208 rotates. The worm gear 209 is driven to rotate. Since the worm wheel 205 meshes with the worm gear 209, the worm wheel 205 drives the rotating shaft 204, which in turn causes the gear 206 to rotate. Since the gear 206 meshes with the rack 202 on the inner wall of the support frame 1, the slider 201 is driven to slide along the support rod 2, thereby adjusting the distance between the mounting frame 203 and the bean outlet tube 302. The self-locking function of the worm wheel 205 and the worm gear 209 ensures that the slider 201 will not shift due to vibration after it is fixed, ensuring accurate and stable row spacing. The servo motor 207 can be turned on simultaneously by the controller 8, or the servo motor 207 can be controlled to operate independently.

[0025] Please see Figure 1-5As shown, a mounting block 3 is installed on the bottom side of the slider 201, and a storage bucket 301 is installed at one end of the mounting block 3. A bean outlet pipe 302 is connected to the bottom side of the storage bucket 301. A funnel 303 is installed on the inner wall of the bottom end of the storage bucket 301 above the bean outlet pipe 302. A feed pipe 304 is installed at the bottom end of the funnel 303. A protective cover 305 is installed on one side of the bean outlet pipe 302. A small motor 306 is installed inside the protective cover 305. A ball 307 is installed inside the bean outlet pipe 302 at the output end of the small motor 306. Several storage holes 308 are equidistantly opened on the outer side of the ball 307. The feed pipe 304 is located directly above one of the storage holes 308.

[0026] The top side of the storage bucket 301 is fitted with a cover plate 4 by a hinge, and a handle 401 is installed at the top edge of the cover plate 4. A plow head 5 is installed on the bottom side of the slider 201, and the plow head 5 is made of metal.

[0027] A connecting frame 6 is installed at the top edge of the support frame 1. Two connecting plates 601 are symmetrically installed on one side of the top of the connecting frame 6. Each connecting plate 601 has an installation hole inside.

[0028] Two mounting frames 7 are symmetrically installed at both ends of the bottom side of the support frame 1. The two sides of the mounting frame 7 are connected by pins and wheels 701. During operation, soybeans are one of the grains frequently used by growers. Soybeans are usually sown by large seeders. For small areas that are difficult for seeders to access, a planter is usually needed to sow soybeans. Therefore, a soybean planter is needed. First, the mounting holes inside the connecting plate 601 on the connecting frame 6 facilitate connection with external power equipment such as tractors. The power equipment pulls the soybeans to complete different plots of work, improving planting efficiency. Then, the handle 401 of the cover plate 4 is opened, and soybeans are put into the storage bucket 301. The funnel 303 guides the soybeans to the feed pipe 304. The small motor 306 is started, and its output end drives the ball 307 to rotate in the soybean outlet pipe 302. The storage holes 308 on the ball 307 are aligned with the feed pipe 304 in sequence. After quantitatively receiving the soybeans, they are transferred to the outlet of the soybean outlet pipe 302 to achieve uniform sowing and avoid blockage and uneven sowing.

[0029] When the external power equipment drives the planter to move, the plow head 5 on the bottom side of the slider 201 turns over the soil to form a planting furrow. Soybeans fall into the furrow from the soybean outlet pipe 302. Then the soil naturally covers the planter or completes the planting process in conjunction with subsequent steps. The planter can move flexibly between plots through the wheels 701 on the mounting frame 7. When the planter is in use, the speed of the servo motor 207 and the small motor 306 can be controlled by the controller 8.

[0030] Working principle: First, the mounting holes inside the connecting plate 601 on the connecting frame 6 facilitate connection with external power equipment such as tractors. The power equipment pulls the soybeans to complete the operation of different plots, improving planting efficiency. Then, the handle 401 of the cover plate 4 is opened, and soybeans are put into the storage bucket 301. The funnel 303 guides the soybeans to the feed pipe 304. The small motor 306 is started, and its output end drives the ball 307 to rotate in the soybean outlet pipe 302. The storage holes 308 on the ball 307 are aligned with the feed pipe 304 in sequence. After quantitatively receiving the soybeans, they are transferred to the outlet of the soybean outlet pipe 302 to achieve uniform sowing and avoid blockage and uneven sowing.

[0031] When the external power equipment drives the planter to move, the plow head 5 on the bottom side of the slider 201 turns over the soil to form a planting trench. Soybeans fall into the trench from the soybean outlet pipe 302. Then the soil naturally covers or cooperates with subsequent processes to complete the planting. The planter can move flexibly between plots through the wheels 701 on the mounting frame 7. When the planter is in use, the speed of the servo motor 207 and the small motor 306 can be controlled by the controller 8.

[0032] According to the soybean variety and soil conditions, the operator sends a command to the servo motor 207 through the controller 8. The servo motor 207 starts, and its output shaft 208 drives the worm gear 209 to rotate. Since the worm wheel 205 meshes with the worm gear 209, the worm wheel 205 drives the rotating shaft 204, which in turn causes the gear 206 to rotate. Because the gear 206 meshes with the rack 202 on the inner wall of the support frame 1, it drives the slider 201 to slide along the support rod 2, thereby adjusting the spacing between the mounting frame 203 and the soybean outlet tube 302. The self-locking function of the worm wheel 205 and the worm gear 209 ensures that the slider 201 will not shift due to vibration after it is fixed, ensuring accurate and stable row spacing. The servo motor 207 can be turned on simultaneously through the controller 8, or the servo motor 207 can be controlled to operate independently.
