Description

Technical Field

[0001] This utility model relates to the field of rapeseed planting equipment, and in particular to a rapeseed planting and seeding machine. Background Technology

[0002] Rapeseed is one of my country's major oil crops. Its tender stems and leaves are edible, making it an important economic crop in my country. Rapeseed is also an excellent green manure. Its root system is relatively developed, and the fallen flowers, leaves, and root residues in the soil have a good fertilizing effect. Rapeseed plants are relatively large and have a high nutrient content. After harvesting, burying the plants in the field to decompose can also fertilize the soil.

[0003] For example, patent document CN217470696U discloses a precision combined seeder for rapeseed planting, including a seed box. Arc grooves are formed on both side walls of the seed box, and sliding arc plates are installed inside the arc grooves. Rotating plates are tightly attached to both side walls of the seed box, and the rotating plates are fixedly connected to the inner arc edges of the arc plates. A connecting box is connected to the bottom of the seed box, and a circular box is connected to the bottom of the connecting box. A rotating rod is installed inside the circular box, and its two ends are rotatably connected to bearings on both side walls of the circular box. This invention uses a second motor to drive the rotating rod to rotate. During rotation, rapeseed seeds in the seed box enter the seed groove and, after rotation, are drawn by gravity and fall into the connecting cylinder. The seeds then fall from the guide tube onto the freshly turned soil, achieving even seeding and preventing seeds from piling up and growing together. The above-mentioned device uses the seed trough to control the number of seeds sown to achieve the purpose of sowing seeds evenly. However, since rapeseed seeds have a strong ability to absorb nutrients, it is necessary to control the row spacing and plant spacing when planting rapeseed to avoid the rapeseed seeds competing for nutrients. Rapeseed is widely planted and the soil fertility varies from place to place. It is necessary to adjust the plant spacing and row spacing of rapeseed planting according to local conditions in order to achieve the best yield. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8As shown, a rapeseed planting seeder includes a seeding vehicle 101, which includes a frame. A handle 103 is bolted to the rear of the frame 101. An adjustment box 102 is welded to the frame 101. Horizontal grooves 104 are symmetrically arranged at the bottom and top of the adjustment box 102. A row spacing adjustment mechanism is provided inside the adjustment box 102. Several seeding mechanisms are provided on one side of the row spacing adjustment mechanism, each seeding mechanism including a seed tube 404. A power mechanism is provided on one side of the frame 101, and a plant spacing adjustment mechanism is provided on the other side of the frame 101. The row spacing adjustment mechanism includes a sliding frame 305 fixedly connected inside the adjustment box 102. A sliding plate 301 is slidably connected inside the sliding frame 305, with radially arranged rear ends of the sliding plate 301. Several adjustment grooves 304 are evenly arranged. The adjustment grooves 304 are slidably connected to the upper end of the seeding tube 404. The lower end of the seeding tube 404 is slidably connected to the transverse groove 104. The front bearing of the adjustment box 102 is rotatably connected to the screw 302. The screw 302 is threadedly connected to the front end of the sliding plate 301. The other end of the screw 302 is welded and fixedly connected to the adjustment nut 303. The operator uses a wrench to turn the adjustment nut 303, which drives the screw 302 to rotate. The screw 302 drives the sliding plate 301 to slide. The sliding plate 301 moves the seeding tube 404 laterally through the cooperation of the several adjustment grooves 304 on it and the transverse groove 104. In this way, the distance between the sowing mechanisms is changed, thereby realizing the function of changing the row spacing of rapeseed planting.

[0031] The power mechanism includes a motor 201 bolted to the top of the adjustment box 102. A first pulley 205 is rotatably connected to one side of the vehicle support 101 via a bearing. A second pulley 206 is located on one side of the first pulley 205 and is rotatably connected to the vehicle support 101 via a bearing. A turning roller 202 is rotatably connected to the front of the vehicle support 101, and a flattening roller 204 is rotatably connected to the rear of the vehicle support 101. The output end of the motor 201 is synchronously connected to the first pulley 205. The first pulley 205 is synchronously connected to one end of the turning roller 202. The first pulley 205 and the second pulley 206 are synchronously connected. The second pulley 206 is synchronously connected to the flattening roller 204. One end of roller 204 is connected to a synchronous belt. Several spirally arranged turning plates 203 are fixedly connected to the turning roller 202. The turning plates 203 are L-shaped. The motor 201 drives the first pulley 205 to rotate. The rotation of the first pulley 205 drives the turning roller 202 and the second pulley 206 to rotate. The second pulley 206 drives the flattening roller 204 to rotate. This enables the seeder to move forward. The arrangement of several L-shaped turning plates 203 on the turning roller 202 can turn up the soil and loosen the soil during the forward movement of the seeder. The flattening roller 204 at the rear can flatten the turned soil and cover the rapeseed seeds with a layer of soil during the flattening process.

[0032] A connecting frame 402 is fixedly connected to the top of the seed tube 404, and a seed storage bin 401 is fixedly connected to the top of the connecting frame 402. A seed-spreading plow 405 is fixedly connected to the bottom of the seed tube 404. A seed-selecting wheel 403 is rotatably connected inside the connecting frame 402. Several seed-collecting slots 406 are evenly arranged on the circumference of the side of the seed-selecting wheel 403. A prism shaft 306 is rotatably connected to a bearing on the adjusting box 102. The prism shaft 306 is slidably connected to the seed-selecting wheel 403. The top of the connecting frame 402 is slidably connected to the transverse groove 104 on the top of the adjusting box 102. Before sowing, the staff fills the seed storage bin with water. An appropriate amount of rapeseed seeds are put into the container 401. Then, as the seeder moves forward, the seed-taking groove 406 on the surface of the seed-selecting wheel 403 can hold a small amount of rapeseed seeds. Then, the seed-selecting wheel 403 rotates and transports the rapeseed seeds to the bottom. Under the action of gravity, the rapeseed seeds fall into the soil from the seed tube 404. The setting of the seed-spreading plow 405 can ensure the depth of the rapeseed seeds falling and protect the lower end of the seed tube 404 from being blocked by the soil. The rotation of the prism shaft 306 drives the seed-selecting wheel 403 to rotate, and the seed-selecting wheel 403 can also limit the sowing mechanism when the gap is adjusted.

[0033] The plant spacing adjustment mechanism includes a protective box 501 fixedly connected to the side of the vehicle frame 101 away from the power mechanism. A drive pulley 502 is rotatably connected inside the protective box 501, and the drive pulley 502 is keyed to the other end of the flattening roller 204. An adjusting wheel frame 503 is rotatably connected inside the protective box 501. Several grooves 504 are evenly arranged around the circumference of the adjusting wheel frame 503. Arc-shaped blocks 505 are slidably connected to the grooves 504. The cross-section of the grooves 504 is trapezoidal to prevent the arc-shaped blocks 505 from slipping. The adjusting wheel frame 503 is fixedly connected to one end of the prism shaft 306. The middle of the adjusting wheel frame 503 is prism-shaped. The arc block 505 and the central prism of the adjusting wheel frame 503 are detachably connected by a spacer rod 506 through a limiting buckle. A transmission belt 507 is fitted onto the drive pulley 502 and the arc block 505. A rod limiting block 509 is provided on one side of the inner wall of the protective box 501. A tightening bracket 508 is detachably connected to the limiting block 509 through a limiting buckle. The tightening bracket 508 is an arc-shaped plastic bracket. The flattening roller 204 rotates, driving the drive pulley 502 to rotate. The drive pulley 502 drives the transmission belt 507 to rotate, which in turn drives the adjusting wheel frame 503 to rotate. The adjusting wheel frame 503 then drives the prism shaft 306 to rotate. Since the transmission belt 507 engages with the arc-shaped block 505, changing the distance from the arc-shaped block 505 to the center of the adjusting wheel frame 503 alters the transmission ratio between the drive pulley 502 and the adjusting wheel frame 503. Multiple sets of spacer rods 506 are provided, allowing for replacement according to the required row spacing. The distance rod 506 is marked with its corresponding transmission ratio, which makes it convenient for staff to replace and avoids multiple adjustments. At the same time, the distance rod 506 can be made of various materials, such as wood or metal, as long as the length meets the requirements. The tensioning bracket 508 can tension the transmission belt 507 to ensure the transmission capacity of the transmission belt 507. Since the tensioning bracket 508 is made of plastic, it has a certain degree of elasticity and can be replaced with limit blocks 509 at different positions according to different transmission ratios, so as to achieve a more flexible tensioning effect.

[0034] Working principle: Before sowing, the operator puts an appropriate amount of rapeseed seeds into the seed storage bin 401, starts the seeder, and the motor 201 drives the first pulley 205 to rotate. The rotation of the first pulley 205 drives the turning roller 202 and the second pulley 206 to rotate. The second pulley 206 drives the flattening roller 204 to rotate, thus enabling the seeder to move forward. The several L-shaped soil turning plates 203 on the turning roller 202 can turn over the soil and loosen it during the forward movement of the seeder. The flattening roller 204 at the rear can press the turned-over soil down. The seeder flattens the rapeseed seeds and covers them with a layer of soil during the flattening process. The flattening roller 204 rotates, driving the drive pulley 502 to rotate. The drive pulley 502 drives the transmission belt 507 to rotate, which in turn drives the adjusting wheel frame 503 to rotate. The adjusting wheel frame 503 then drives the prism shaft 306 to rotate. As the seeder moves forward, the seed-collecting groove 406 on the surface of the seed-selecting wheel 403 can hold a small amount of rapeseed seeds. The prism shaft 306 then rotates, driving the seed-selecting wheel 403 to rotate as well. The seed-selecting wheel 403 transports the rapeseed seeds downwards, where they are released under gravity. The rapeseed seeds fall into the soil through the seed tube 404. The seed-spreading plow 405 ensures the depth of the rapeseed seeds and protects the lower end of the seed tube 404 from soil blockage. When row spacing needs to be adjusted, the worker uses a wrench to turn the adjusting nut 303. The adjusting nut 303 drives the screw 302 to rotate, and the screw 302 drives the sliding plate 301 to slide. The sliding plate 301, through the cooperation of several adjusting grooves 304 and the transverse groove 104, moves the seed tube 404 laterally. The prism shaft 306 also serves as a guide and limiter. The function of this mechanism is to change the distance between the sowing mechanisms, thereby changing the row spacing of rapeseed planting. When plant spacing needs to be adjusted, since the transmission belt 507 cooperates with the arc block 505, changing the distance from the arc block 505 to the center of the adjusting wheel frame 503 can change the transmission ratio between the drive pulley 502 and the adjusting wheel frame 503. Multiple sets of spacers 506 are provided, and spacers 506 can be replaced according to the required row spacing. The surface of the spacer 506 is marked with its corresponding transmission ratio, which makes it convenient for staff to replace and avoids multiple adjustments.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
