Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, in particular to a special potato seed braiding machine. Background Art

[0002] The potato (Solanum tuberosum) is a globally important food crop, its importance not only reflected in agricultural production but also has profound impacts on nutrition, the economy, and society. Rich in nutrients, it is a high-energy, low-fat food rich in vitamin C, B vitamins, potassium, dietary fiber, and antioxidants. With the global population increasing, food demand continues to intensify. Traditional staple foods (such as rice and wheat) place high demands on environmental conditions, particularly limited water resources and arable land. In this context, the potato, with its high yield, rich nutrition, and strong adaptability, has become an effective food supplement. The emergence of hybrid potato seeds has provided a new approach to improving potato productivity and quality in China and globally. Agronomically, hybrid potato seeds require three seeds per hole and controlled plant spacing. Therefore, seed braiding machines are used to braid the hybrid potato seeds before planting.

[0003] Currently, seed braiding machines on the market primarily cater to vegetable seeds, which differ from the requirements for braiding potato hybrid seeds. The seed-feeding mechanism of these machines is incompatible with the shape of potato hybrid seeds. During operation, the paper tape conveying speed and tension cannot be maintained constant. As the paper tape is wound on the reel, the diameter of the reel gradually increases, while the diameter of the paper tape reel gradually decreases. This causes changes in the paper tape conveying speed and tension, making it impossible to match the seeding speed with the paper tape conveying speed. This results in failure to meet the seed quantity and plant spacing requirements, directly impacting subsequent planting. Summary of the Invention

DETAILED DESCRIPTION

[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] like Figure 1 As shown, a preferred potato seed braiding machine of the present invention has a vacuum pump installed in a base box 1, and a chassis 10 mounted on the base box 1. The vacuum pump provides negative and positive pressure to the seed suction device 4. The negative pressure causes the seed suction disc 43 to absorb seeds from the seed box 5, while the positive pressure blows off excess seeds from the seed suction disc 43. A paper tape reel 2 is mounted on the chassis 10, with a paper tape guide mechanism 3 located above the paper tape reel 2. A seed box 5 and the seed suction device 4 are mounted on the chassis 10, with a material guide mechanism 6 located below the seed suction device 4. A winding mechanism 7, a rope reel 8, and a reeling mechanism 9 are mounted on the chassis 10. The machine includes a rope reeling motor and a reeling motor. The rope reeling motor drives the rope reeling mechanism 8 to rotate at a set paper tape linear velocity, while the reeling motor drives the reeling mechanism 9 to rotate at a set torque. The reeling motor is a torque motor that controls the paper tape tension to remain constant, while the rope reeling motor is a stepper motor that controls the paper tape linear velocity to remain constant. The paper tape is installed on the paper tape reel 2. The rope-taking motor and the winding motor are the power sources for the entire paper tape movement. The paper tape passes through the paper tape guiding mechanism 3, the material guiding mechanism 6, the winding mechanism 7, the rope-taking mechanism 8, and the winding mechanism 9 in sequence.

[0019] Winding the paper tape onto the reel 9 is a crucial process. During the winding process, the diameter of the reel gradually increases, while the diameter of the paper tape reel 2 gradually decreases. Maintaining constant tension and constant tape speed throughout the entire process is crucial. Excessive tension can cause the tape to deform or even break, resulting in poor weaving results or even ineffective seed wrapping. Excessive tension can lead to loosening of the reel. To maintain constant tension during the winding process, the output torque of the reel motor driving the reel must increase as the diameter of the reel around the paper tape increases. To maintain a constant tape speed, the speed of the reel connecting shaft 93 must also decrease. The reel motor of the present invention drives the reel mechanism 9 to rotate according to a set torque. The reel motor is a torque motor that outputs power at a constant torque, meeting these requirements. The reel motor ensures a constant tape speed, matching the seed suction speed with the tape speed, improving the uniformity of plant spacing and the weaving effect after weaving.

[0020] like Figure 4As shown, it includes a seed suction motor, and the seed suction device 4 includes a seed suction disc 43, a synchronous pulley 41, a synchronous belt 42, a fourth mounting shaft 44, a steel belt 45, a needle 46, a needle fixing plate 47, a second L-shaped fixing plate 48, a slider 49, a second mounting plate 410, and a synchronous belt cover 411; the seed suction motor drives the synchronous pulley 41 to rotate, and the synchronous pulley 41 is linked to the seed suction disc 43 through the synchronous belt 42; the synchronous belt cover 411 is installed on the chassis 10 to protect the synchronous belt 42, and the seed suction disc 43 is installed on the second mounting plate 410 through the fourth mounting shaft 44, the steel belt 45 is installed in the middle of the seed suction disc 43, the needle 46 is installed in the middle of the needle fixing plate 47, the needle fixing plate 47 is connected to the second L-shaped fixing plate 48, and is installed on the second mounting plate 410 through the slider 49; three circles of seed suction holes are provided on the seed suction disc 43. Seed suction speed The expression is: Where: The speed of the rope-retracting motor is the linear speed of the paper tape; is the diameter of the seed suction tray, b is the number of seed suction holes in one circle of the seed suction tray, and c is the set value of the plant spacing.

[0021] Under the action of negative pressure, the seed suction tray 43 draws seeds from the seed box 5 and passes through a seed cleaning mechanism composed of a needle 46, a needle fixing plate 47, a second L-shaped fixing plate 48, and a slider 49. In addition, the seed cleaning mechanism also includes a seed cleaning nozzle. A vacuum pump provides positive pressure to the seed cleaning nozzle, which can blow off excess seeds on the seed suction tray 43, ensuring that one seed is planted in each hole. Because the seed suction tray 43 is provided with three circles of seed suction holes, three seeds are sucked each time, meeting the planting requirement of three potato hybrid seeds per hole. The seeds continue to move with the seed suction tray 43. At the lowest point, the seed suction tray 43 blocks the air holes, and the seeds fall onto the paper tape in the V-shaped paper guide groove 61. If there are any seeds that have not fallen off, they will be scraped off the air holes by the scraper 63 to ensure that the holes in the seed suction tray are clean.

A pulley 210 is mounted on the third connecting shaft 29, and a second limiting slip ring 211 is mounted on the third mounting shaft 29. The paper tape is fixed between the paper tape slots 24 and then placed on the paper tape reel 2 connected to the chassis 10. The first limiting slip ring 23 limits the range of movement of the paper tape reel 2 on the first mounting shaft 22. The pulley 210 above presses the paper tape downward to determine the output position and size of the paper tape. Under the action of gravity and the compression spring 26, the connecting plate 28 continuously approaches a proximity switch as the paper tape is used. When the paper tape stock is low, the connecting plate 28 triggers the proximity switch to issue an alarm signal, reminding the staff to change the paper tape.

If the paper breaks, an alarm will be issued on the screen. The second paper tape guiding shaft 35 adjusts the distance between the paper tape and the diffuse reflection photoelectric switch 34, and the third paper tape guiding shaft 36 adjusts the height of the paper tape entering the next step.
