Description

Technical Field

[0001] The invention relates to the technical field of seed drills, in particular to a corn seed drill capable of adjusting the seeding depth. Background Art

[0002] A seeder is an agricultural machine that is used to sow seeds into the soil according to certain row spacing, plant spacing, depth and sowing rate requirements to achieve efficient and accurate sowing operations. Common types of seeders include drill seeders, hole seeders, precision seeders, etc. Different types are suitable for different crops and planting needs. Drill seeders can sow seeds evenly in strips, and are suitable for densely planted crops such as wheat and barley; hole seeders sow seeds at a certain hole spacing, with a number of seeds sown in each hole, and are commonly used for crops such as corn and cotton.

[0003] In today's agricultural production field, the existing corn planters have exposed obvious functional limitations in actual use. Most of the corn planters on the market currently focus on the two basic links of furrowing and sowing. However, in the complete corn planting process, it is far from enough to just complete furrowing and sowing. The follow-up also involves several essential processes such as watering, fertilizing, and burying seeds. In the face of these additional processes, the current common practice is to use additional equipment to complete them, or rely on manual operation. However, this mode of operation has many disadvantages. On the one hand, the use of additional equipment will increase the equipment cost and maintenance cost, and more manpower will be required to operate these equipment; manual operation is not only labor-intensive, but also due to limited physical strength and energy, it is prone to problems such as irregular operation and low efficiency. This method of relying on external equipment or manual completion of the remaining processes has greatly affected the overall efficiency of corn planting, and it is also not in line with the current development concept of energy conservation and environmental protection.

[0017] One of the output ends of the dual-axis motor 408 passes through the protective shell 409 and is connected to the end outside the protective shell 409 and the end of the rotating shaft 417 away from the pressure rod 405. A pulley 414 is fixedly sleeved, and a transmission belt 411 is arranged between the two pulleys 414. The conveying pipe 415 is a metal telescopic pipe, and the conveying pipe located at the pressure rod 405 is a natural rubber pipe. A shock absorber frame 413 is arranged at the upper end of the front side of the upper support column 401, and a tail rod 410 is fixedly arranged at the lower end of the shock absorber frame 413. An injection hole is opened at the upper end of the storage water tank 412, and a sealing plug is arranged on the inner thread sleeve of the injection hole. A small water pump 423 is connected to the lower end of the rear end of the storage water tank 412 through a pipeline, and a nozzle is fixedly arranged at the output end of the small water pump 423, and the angle of the nozzle faces the conveying pipe 415. The front end of the pressure rod 405 is arranged to be inclined. The rear ends of the multiple upper support columns 401 are fixedly arranged through a connecting truss 2, a corn seed storage box 1 is fixedly arranged on the upper end of the connecting truss 2, a plurality of supporting leg wheels 3 are fixedly arranged on the lower end of the connecting truss 2, and the upper end of the feed hopper 416 and the lower end of the corn seed storage box 1 are through-arranged.

[0018] Specifically: During use, if sowing is carried out on a plot with too many weeds or debris, a protective shell is required to protect the pulley 414, the transmission belt 411, the single-toothed toggle wheel 422 and the spring telescopic rod 421 related structures to prevent the device from being stuck by weeds or debris during use, thereby affecting the use of the device. Figure 5 As shown, a portion of the delivery pipe 415 parallel to the pressure rod 405 is made of natural rubber material, which has excellent elasticity and high resilience. When the delivery pipe 415 here is compressed and retracted by the pressure rod 405, the delivery pipe 415 can rebound after being compressed, so as to control the stopping or releasing of corn seeds during sowing. The rotation speed of the dual-axis motor 408 can be controlled, or the single-tooth toggle wheel 422 can be replaced with other teeth to perform quantitative feeding and sowing. Since the plowing rod 404 is connected to the fixing seat 402 through a thread, the plowing rod 404 can be adjusted by removing the bolts to adjust the position of the plowing rod 404 inside the fixing seat 402, thereby adjusting the height of the plowing rod 404, and adjusting the plowing depth to adjust the sowing depth of the corn seeds.

[0019] By combining the storage water tank 412 with the small water pump 423, the fertilizer water is sprayed to the outlet of the delivery pipe 415 through the pipe, so as to achieve synchronous fertilization and watering during sowing and improve the survival rate of seeds. The dual-axis motor 408 drives the crushing wheel 407 to rotate at high speed, crushing the soil turned up by the plow head 406 and covering the seeds, completing the whole process of furrowing, sowing and covering the soil without the need for additional equipment. The plow rod 404 is fixed in the fixing seat 402 by bolts. After removing the bolts, the position of the plow rod 404 can be adjusted up and down to change the depth of the plow head 406 into the soil to adapt to different soil conditions, such as shallow sowing for clay and deep sowing for sand. The lower support column 403 and the upper support column 401 form a rigid support frame to ensure stable operation of the equipment after depth adjustment and avoid operation deviation. The dual-axis motor 408 drives the rotating shaft 417 to drive the single-tooth toggle wheel 422 to rotate, and its single tooth periodically squeezes the inclined surface of the pressure rod 405. The pressure rod 405 compresses the spring telescopic rod 421 and compresses the conveying pipe 415 made of natural rubber material, thereby achieving intermittent closure of the pipe and controlling the frequency of seed falling.

[0020] By replacing a single-toothed toggle wheel 422 with different numbers of teeth or adjusting the speed of the dual-axis motor 408, the action frequency of the pressure rod 405 can be changed, and the sowing spacing can be accurately controlled, such as sowing one hole per tooth rotation. The rotating shaft 417 drives the stirring wheel 418 to rotate in the storage water tank 412, forcibly mixing water and powder fertilizer to avoid precipitation, ensure uniform fertilizer and water concentration, and improve the fertilization effect. One end of the dual-axis motor 408 drives the crushing wheel 407, and the other end is linked to the rotating shaft 417 through the pulley 414 and the transmission belt 411. A single motor drives soil treatment, fertilizer and water mixing, and sowing control at the same time, reducing additional energy consumption. Sowing control is achieved through pure mechanical structures such as the pressure rod 405 and the single-toothed toggle wheel 422, reducing the failure rate and maintenance cost. The plow rod 404, the protective shell 409, etc. are connected by bolts or snap rings, which is convenient for quick replacement of worn parts such as the plow head 406.

[0021] This technology integrates the processes of trenching, sowing, covering, fertilizing, and watering into a single device through structural linkage design, modular adjustment, and utilization of material properties, significantly reducing manpower and equipment investment. Its mechanical precision control and deep adaptability are particularly suitable for agricultural scenarios with limited resources, and it has the advantages of high efficiency, energy saving, and low cost.

[0022] Working principle: Before use, use the tail of the tractor-related agricultural equipment to connect with the connecting truss 2, then store a certain amount of corn seeds in the corn seed storage box 1, and then open the sealing plug to store a certain amount of fertilizer water or other water in the storage water tank 412; When in use, start the tractor to drive the device to move in the field. During the movement, use the plow head 406 to open the planting pit, and at the same time open the control valve on the conveying pipeline 415, the double-axis motor 408 and the small water pump 423. After the control valve on the conveying pipeline 415 is opened, the corn seeds in the corn seed storage box 1 pass through the feed hopper 416 and flow out from the lower end of the conveying pipeline 415. After the small water pump 423 is turned on, the fertilizer water in the storage water tank 412 is sprayed on the conveying pipeline 415, and flows downward from the end of the conveying pipeline 415, so that the fertilizer water and seeds flow out at the same time, thereby increasing the survival rate of the seeds. After the double-axis motor 408 is started, the rotating shaft 417 is driven to rotate through the pulley 414 and the transmission belt 411. The rotation of the rotating shaft 417 drives the stirring wheel 418 and the single-tooth toggle wheel 422 to rotate. The rotation of the stirring wheel 418 can stir the inside of the storage water tank 412. If powder additives are added to the fertilizer water, it can be stirred evenly. During the rotation of the single-tooth toggle wheel 422, when the single-tooth toggle wheel 422 rotates, the stirring wheel 418 can stir the inside of the storage water tank 412. When the single tooth of the toothed toggle wheel 422 rotates and contacts the inclined surface of the pressure rod 405, it squeezes the pressure rod 405 to move to one side. During the movement of the pressure rod 405, the spring telescopic rod 421 is compressed, and at the same time, the pressure rod 405 collapses the natural rubber material part of the conveying pipe 415 to prevent the corn seeds from flowing down. When the single-toothed toggle wheel 422 continues to rotate and does not contact the inclined surface of the pressure rod 405, the pressure rod 405 returns to its original position under the elastic force of the spring telescopic rod 421, achieving staged stopping of feeding and sowing of corn seeds with intervals. At the same time, the dual-axis motor 408 starts to drive the crushing wheel 407 to rotate, which can crush the raised soil plowed out by the plow head 406 to bury the seeds. Therefore, the device can realize multiple functions such as cultivating planting pits, sowing with intervals, positioning watering, stirring and mixing fertilizer and water, burying seeds, etc., and the power equipment can be realized only by the dual-axis motor 408 in conjunction with the small water pump 423, which is more energy-saving and environmentally friendly to use, and has high efficiency.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
