Description

Technical Field

[0001] This application relates to the field of sowing equipment technology, specifically a high-yield sowing device for high-oil soybeans in dryland areas. Background Technology

[0002] In the field of agricultural planting, soybeans are an important economic crop, and the quality and yield of their cultivation are directly related to agricultural economic benefits.

[0003] An existing patent (publication number: CN219999993U) discloses a precision soybean planter, including a material hopper mounted on a frame. A throat is located at the center of the bottom of the material hopper, and a distribution pipe is located at the output end of the throat. A slider is slidably connected to the internal sliding cavity of the distribution pipe, and a through hole is provided on the slider. A discharge pipe is located at the output end of the distribution pipe. A push rod is connected to the surface of the slider, and a connecting rod is located at the end of the push rod away from the slider. A telescopic rod is mounted on the connecting rod. A controller is also provided on the frame, connected to the telescopic rod and used to control the reciprocating frequency of the telescopic rod. The reciprocating motion of the telescopic rod controls the falling of soybeans, and the frequency of the telescopic rod controlled by the controller controls the falling speed of the soybeans, thereby achieving precision planting.

[0004] However, in actual dryland high-oil soybean cultivation, significant differences exist in soil fertility, texture, and moisture content across different regions. Furthermore, different soybean varieties vary in size, weight, and germination rate. This leads to diverse requirements for sowing intervals and row spacing. For example, in fertile soils, to prevent overly dense soybean plant growth and nutrient competition, sowing intervals and row spacing need to be appropriately increased; conversely, in less fertile soils, sowing intervals and row spacing can be appropriately reduced to improve land utilization. Similarly, different soybean sizes require different sowing densities. The aforementioned devices cannot flexibly adjust sowing intervals and row spacing according to different soil conditions and soybean characteristics, failing to fully meet the diverse needs of actual cultivation and thus impacting the cultivation effect and yield of dryland high-oil soybeans to some extent. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a high-yield, high-oil soybean planting device for dryland areas, which has advantages such as easy adjustment and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a high-yield sowing device for high-oil soybeans in dryland, comprising a tractor vehicle and a connecting end of the tractor vehicle located away from the direction of travel, wherein a support frame is fixedly installed on the connecting end along the width direction of the tractor vehicle, and a set of sowing mechanisms is installed on the end of the support frame away from the tractor vehicle. The sowing mechanism includes a disc-shaped shell, a connecting cylinder coaxially connected to the disc-shaped shell, a material distribution plate fixedly connected to the outer surface of the connecting cylinder, the material distribution plate being located inside the disc-shaped shell, the circumferential surface of the material distribution plate contacting the inner wall of the disc-shaped shell, a set of circumferentially equidistant material grooves being opened along the radial direction of the material distribution plate, an adjusting plate being slidably inserted into the interior of each material groove, and a driving mechanism being provided on the side of each adjusting plate near the connecting cylinder for adjusting the groove depth of the material groove where the adjusting plate is located; The seeding mechanism also includes a storage hopper located above the disc-shaped shell. The bottom end of the storage hopper is fixedly connected to the disc-shaped shell, and the bottom end of the disc-shaped shell is fixedly connected to a discharge pipe that is arranged radially and vertically downwards.

[0007] Furthermore, the upper surface of the support frame is provided with a set of linearly arranged connecting holes, and each disc-shaped shell is fixedly connected to a connecting frame on its outer surface. Each connecting frame is connected to its corresponding connecting hole by bolts.

[0008] The above scheme facilitates the adjustment of the spacing between adjacent sowing units, thus adapting to the diverse requirements for sowing row spacing under different soil conditions and planting scales.

[0009] Furthermore, the support frame is rotatably connected to two rotating shafts along the width direction of the traction vehicle, and a rectangular shaft is fixedly connected between the two rotating shafts. The rectangular shaft is slidably inserted into each connecting cylinder, and one end of one of the rotating shafts is fixedly connected to the external motor output end.

[0010] The above solution enables the synchronous rotation of multiple seeding mechanisms without affecting the spacing adjustment of the seeding mechanisms, thus ensuring the coordination and flexibility of the seeding operation.

[0011] Furthermore, the support frame is rotatably connected to a detection shaft along the width direction of the traction vehicle. A speed sensor for detecting the rotational speed of the detection shaft is installed at one end of the detection shaft, and a transmission roller is provided at the other end of the detection shaft. The circumferential surface of the transmission roller abuts against the circumferential surface of the traction vehicle wheel.

[0012] With the above scheme, when the detection shaft stops rotating, the vehicle is in a stopped state, the external motor stops rotating, and the running status and speed of the traction vehicle are monitored, and the linkage motor is synchronously controlled. Secondly, when it is necessary to reduce the sowing spacing, the motor speed can be increased, and when the sowing spacing is increased, the motor speed can be reduced. The specific control logic method is to calculate the motor speed to be adjusted based on the preset correspondence between the sowing spacing and the motor speed, and implement the control by using the detected vehicle speed and the required sowing spacing.

[0013] Furthermore, the transmission roller is made of rubber.

[0014] Through the above solution, the rubber material has good friction and elasticity, which can better fit the surface of the traction vehicle, accurately transmit power, and reduce wear on the surface of the traction vehicle.

[0015] Furthermore, the storage hopper is made of transparent acrylic material.

[0016] The above method allows for easy and intuitive viewing of the remaining amount of soybeans inside the storage hopper, enabling timely replenishment.

[0017] Furthermore, the driving mechanism includes a motor arranged radially along the distribution plate, the output end of the motor is fixedly connected to a threaded rod, the threaded rod is rotatably connected to the inner bottom wall of the material trough, and a sleeve is threadedly connected to the outer surface of the threaded rod, the top end of the sleeve is fixedly connected to its corresponding adjustment plate.

[0018] The above scheme uses a motor to drive the threaded rod to rotate, which in turn moves the sleeve and the adjusting plate, thereby achieving precise adjustment of the depth of the material trough.

[0019] Furthermore, each of the adjusting discs is fixedly connected to a set of guide rods arranged in the radial direction of the distributing disc, and each guide rod is slidably inserted into the inner bottom wall of its corresponding material trough.

[0020] The above scheme guides the movement of the adjusting disc by means of a guide rod, ensuring the stability of the adjusting disc's movement and preventing it from deviating during the movement.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This high-yield, high-oil soybean planting device for dryland uses an adjustable regulating disc on the feeding tray of the planting mechanism. By adjusting the depth of the feeding trough where the regulating disc is located using a drive mechanism, the planting amount at each planting point can be adjusted. It can flexibly adjust the planting amount at each planting point according to the size, weight, germination rate, and other characteristics of different soybean varieties, ensuring that soybeans obtain suitable growth conditions in dryland planting, improving the emergence rate and growth quality of soybeans, and ultimately helping to increase the yield of high-oil soybeans in dryland.

[0022] By opening a set of linearly arranged connecting holes on the support frame, the connecting frame fixedly connected to the outer surface of the disc shell can be connected to different connecting holes by bolts, which facilitates the adjustment of the spacing between adjacent sowing mechanisms, thereby realizing the adjustment of row spacing. By controlling the rotation speed of the distributing disc, the sowing spacing can be adjusted, avoiding the soybean plants growing too densely and competing for nutrients in soils with high fertility, improving land utilization in soils with low fertility, fully meeting the diverse needs in actual planting, and improving the planting effect and yield of high-oil soybeans in dryland areas.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figures 1-5 This embodiment of a high-yield, high-oil soybean planting device for dryland includes a tractor vehicle 1 and a connecting end 101 of the tractor vehicle 1 located away from the direction of travel. The device is characterized in that: a support frame 2 is fixedly installed on the connecting end 101 along the width direction of the tractor vehicle 1, and a set of planting mechanisms 3 is installed on one end of the support frame 2 away from the tractor vehicle 1.

[0027] The sowing mechanism 3 includes a disc-shaped shell 301, which is rotatably connected to a coaxially arranged connecting cylinder 302. A set of linearly arranged connecting holes are provided on the upper surface of the support frame 2. A connecting frame 5 is fixedly connected to the outer surface of each disc-shaped shell 301, and each connecting frame 5 is connected to its corresponding connecting hole by bolts. This facilitates adjustment of the spacing between adjacent sowing mechanisms 3, thus adapting to diverse requirements for sowing row spacing under different soil conditions and planting scales. A distribution plate 303 is fixedly connected to the outer surface of the connecting cylinder 302. The distribution plate 303 is located inside the disc-shaped shell 301, and its circumferential surface contacts the inner wall of the disc-shaped shell 301. A set of circumferentially equidistant material-carrying grooves 304 are provided radially on the distribution plate 303. Each material-carrying groove 304... Inside the 4, adjustment discs 305 are slidably inserted. Each adjustment disc 305 is equipped with a drive mechanism 4 on the side near the connecting cylinder 302. This mechanism is used to adjust the depth of the material trough 304 where the adjustment disc 305 is located, thereby adjusting the seeding amount of a single seeding point. The drive mechanism 4 includes a motor 401 arranged radially along the distribution disc 303. The output end of the motor 401 is fixedly connected to a threaded rod 402. The threaded rod 402 is rotatably connected to the inner bottom wall of the material trough 304. A sleeve 403 is threadedly connected to the outer surface of the threaded rod 402. The top end of the sleeve 403 is fixedly connected to the corresponding adjustment disc 305. The motor 401 drives the threaded rod 402 to rotate, thereby moving the sleeve 403 and the adjustment disc 305 to achieve precise adjustment of the depth of the material trough 304.

[0028] The sowing mechanism 3 also includes a storage hopper 306 disposed above the disc-shaped shell 301. The bottom end of the storage hopper 306 is fixedly connected to the disc-shaped shell 301. A discharge pipe 307 is fixedly connected to the bottom end of the disc-shaped shell 301, which is arranged radially and vertically downwards. Soybeans are accurately sown into the soil through the discharge pipe 307. The support frame 2 is rotatably connected to two rotating shafts 6 along the width direction of the traction vehicle 1. A rectangular shaft 7 is fixedly connected between the two rotating shafts 6. The rectangular shaft 7 is slidably inserted into each connecting cylinder 302. One end of one of the rotating shafts 6 is fixedly connected to the output end of an external motor, which can synchronously drive multiple sowing mechanisms 3 to rotate. At the same time, it does not affect the spacing adjustment of the sowing mechanism 3, ensuring the coordination and flexibility of the sowing work. The storage hopper 306 is made of transparent acrylic material, which makes it easy to see the remaining amount of soybeans inside the storage hopper 306 and replenish them in time. Each adjusting plate 305 is fixedly connected to a set of guide rods 404 arranged in the radial direction of the distributing plate 303. Each guide rod 404 is slidably inserted into the inner bottom wall of its corresponding material trough 304. The guide rods 404 guide the movement of the adjusting plate 305, ensuring the stability of the movement of the adjusting plate 305 and preventing the adjusting plate 305 from deviating during the movement.

[0029] The support frame 2 is rotatably connected to the detection shaft 8 along the width direction of the traction vehicle 1. A speed sensor 9 for detecting the rotational speed of the detection shaft 8 is installed at one end of the detection shaft 8, and a transmission roller 10 is set at the other end of the detection shaft 8. The circumferential surface of the transmission roller 10 abuts against the circumferential surface of the wheel of the traction vehicle 1. When the detection shaft 8 stops rotating, the vehicle is in a stopped state, and the external motor stops rotating, thereby monitoring the running status and speed of the traction vehicle 1 and synchronously controlling the linkage motor. Secondly, when it is necessary to reduce the sowing spacing, the motor speed can be increased, and when the sowing spacing is increased, the motor speed can be reduced. The specific control logic method is to calculate the motor speed to be adjusted based on the preset correspondence between the sowing spacing and the motor speed, and implement control by using the detected vehicle speed and the required sowing spacing. The transmission roller 10 is made of rubber, which has good friction and elasticity, can better fit the surface of the traction vehicle 1, accurately transmit power, and reduce wear on the surface of the traction vehicle 1.

[0030] The working principle of the above embodiment is as follows: First, the device is connected to the traction vehicle 1 via the connecting end 101. Based on the actual soil conditions, planting scale, and soybean variety characteristics, the sowing mechanism 3 is adjusted accordingly. Through the linearly arranged connecting holes on the support frame 2, bolts are used to connect the connecting frame 5 on the outer surface of the disc-shaped shell 301 to the connecting holes at appropriate positions, thereby adjusting the spacing between adjacent sowing mechanisms 3 to achieve row spacing adjustment. According to the required sowing spacing, the depth of the trough 304 where the adjusting disc 305 is located is adjusted using the drive mechanism 4. The motor 401 in the drive mechanism 4 drives the threaded rod 402 to rotate, causing the sleeve 403 and the adjusting disc 305 to move. The guide rod 404 ensures the stable movement of the adjusting disc 305. To control the sowing amount, the traction vehicle 1 and the external motor are started. The traction vehicle 1 drives the device forward, and the motor drives the rectangular shaft 7 to rotate through the rotating shaft 6. The rectangular shaft 7 then drives each connecting cylinder 302 to rotate, thereby causing the distributing disc 303 to rotate inside the disc shell 301. The soybeans in the storage hopper 306 enter the disc shell 301. As the distributing disc 303 rotates, the soybeans fall into the feeding trough 304. When the feeding trough 304 rotates to above the feeding pipe 307, the soybeans are accurately sown into the soil from the feeding pipe 307.

[0031] During device operation, the transmission roller 10 at one end of the detection shaft 8 contacts the surface of the traction vehicle 1, transmitting the rotation of the traction vehicle 1 to the detection shaft 8. The speed sensor 9 detects the rotational speed of the detection shaft 8, thereby monitoring the operating status and speed of the traction vehicle 1. When the detection shaft 8 stops rotating, it indicates that the vehicle has stopped, and the external motor also stops rotating. Furthermore, based on the preset relationship between the sowing spacing and the motor speed, combined with the detected vehicle speed and the required sowing spacing, the motor speed that should be adjusted can be calculated and controlled. This allows for flexible adjustment of the sowing spacing to meet different planting needs and improve the planting effect and yield of high-oil soybeans in dryland areas.
