Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, in particular to a potato sowing device. Background Art

[0002] Potatoes have multiple characteristics such as food, vegetables and fruits. They are one of the important food varieties in many countries in the world and are listed among the seven major food crops, second only to rice, corn and wheat. In recent years, my country's potato planting area has stabilized at about 70 million mu, and the output has been nearly 90 million tons, accounting for about a quarter of the world's total, and the output has ranked first in the world for many years.

[0003] In the process of potato planting, commonly used potato-rowing devices include clamp type, needle type, chain spoon type and conveyor belt type. Among them, the chain spoon type potato planter is widely used in agricultural production due to its advantages such as accurate and uniform sowing, convenient plant spacing adjustment, little damage to seed potatoes, and applicability to various soil conditions. However, in the actual sowing process, the potato seed spoon may not scoop up the seeds or the seeds may be shaken off due to the shaking of the chain during transportation, which will cause missed seeds when the potato planter is sowing.

[0004] Therefore, those skilled in the art are committed to developing a potato sowing device to reduce the occurrence of missed sowing during the sowing process. Summary of the invention

[0022] like Figure 1-4 As shown, a potato sowing device comprises a driving shaft 1, on which a first replanting device 2 and a second replanting device are arranged in parallel and at intervals, and the first replanting device 2 and the second replanting device have the same structure. In this embodiment, the replanting device is arranged in two groups, and in other embodiments, other numbers of replanting devices can be arranged according to actual needs, wherein the first replanting device 2 comprises a driving sprocket 21, and a driven sprocket 22 is arranged below the driving sprocket 21, and the driving sprocket 21 and the driven sprocket 22 are connected by a bent plate chain 23, and the driving shaft 1 provides power for the first replanting device 2, and the driving shaft 1 drives the driving sprocket 2 1 rotates, the driving sprocket 21 drives the driven sprocket 22 to rotate through the bent plate chain 23, a plurality of seed spoons 24 are arranged on the bent plate chain 23 at intervals, the seed spoons 24 rotate with the bent plate chain 23, and turn over at the highest point of the bent plate chain 23, the left and right sides of the bent plate chain 23 are provided with a beam-type photoelectric sensor 25, the rear side of the bent plate chain 23 is provided with a seed guide tube 26 with two ends opened, the inner diameter of the seed guide tube 26 is slightly larger than the outer diameter of the seed spoon 24, so that the seed potatoes are not easy to fall, and a seed supplement tube 27 is arranged on the top of the seed guide tube 26, and a plurality of through holes are opened on the seed supplement tube 27, so as to facilitate the observation of the internal situation of the seed supplement tube 27.

[0023] In this embodiment, a seeding box 3 is arranged on the top of the seeding tube 27, one end of the seeding tube 27 is connected to the seeding box 3, and the other end is located above the opening of the seed guide tube 26. The seed potatoes can slide from the seeding box 3 to the seed guide tube 26 along the seeding tube 27. A seeding guide tube cover 271 is hinged at the bottom of the seeding tube 27. A DC telescopic electromagnet 272 is arranged on the outer wall of the seeding tube 27. A first connecting rod 273 is arranged at the end of the DC telescopic electromagnet 272. A second connecting rod 274 is hinged at one end of the first connecting rod 273 away from the DC telescopic electromagnet 272. The second connecting rod 274 is fixedly connected to the seeding guide tube cover 271. A return spring 275 is provided on the side wall, one end of the return spring 275 is connected to the side wall of the replanting tube 27, and the other end is connected to the replanting guide tube cover 271. When the return spring 275 is in a freely extended state, the replanting guide tube cover 271 is in a closed state. When replanting is required, the DC telescopic electromagnet 272 is controlled to contract, driving the first connecting rod 273 and the second connecting rod 274 to open the replanting guide tube cover 271. At this time, the return spring 275 is in a stretched state, and the seed potatoes fall from the replanting tube 27 into the seed guide tube 26. After the replanting is completed, the DC telescopic electromagnet 272 is powered off, and the return spring 275 elastically contracts to close the replanting guide tube cover 271.

[0024] In the present embodiment: a seed box 4 is arranged on the side of the bent plate chain 23 away from the seed guide tube 26, a mounting plate 5 is arranged on the seed box 4, a bearing mounting seat 6 is arranged on the mounting plate 5, the drive shaft 1 is rotatably matched with the bearing mounting seat 6, a support frame 7 is arranged on the top of the mounting plate 5, one end of the support frame 7 is fixedly connected to the mounting plate 5, and the other end is fixedly connected to the reseeding box 3.

[0025] In the present embodiment: a seed protection fence 8 is arranged on the top of the seed box 4, and a plurality of through holes are opened on the seed protection fence 8. During use, the seed spoon 24 and the internal conditions of the machine can be observed through the through holes. The opposing photoelectric sensors 25 are arranged on the opposite side walls of the seed protection fence 8. In the present embodiment, the opposing photoelectric sensors 25 are arranged in three groups to make the detection results more accurate. In other embodiments, they can be selected according to actual conditions. A control box 28 is provided on the seed supplement box 3, and the control box 28 is electrically connected to the opposing photoelectric sensor 25. The opposing photoelectric sensor 25 can transmit the received signal back to the control box for processing.

[0026] In this embodiment: a through hole is opened at the bottom of the seed spoon 24. When the seed spoon 24 scoops up seeds in the seed box 4, impurities such as soil may be attached. The bottom hole is convenient for the impurities to fall. After the seed spoon 24 is turned over, the bottom hole is convenient for catching the seed potatoes dropped by the next seed spoon 24.

[0027] When in use: the seed spoon 24 scoops seed potatoes from the seed box driven by the curved plate chain 23 and moves upward through the seed protection fence 8. The photoelectric sensor 25 provided on the seed protection fence 8 can detect the seed spoon 24 in turn. If there are seed potatoes in the seed spoon 24, the light emitted by the transmitting end will be blocked by the seed potatoes, and the light intensity received by the receiving end will be reduced or completely disappear. The control box 28 can process the signal received by the photoelectric sensor 25. When it is found that there are no seed potatoes in the seed spoon 24, before the empty seed spoon 24 is turned over, the reseeding conduit cover 271 is opened to reseed the empty seed spoon 24. The reseeded potato seeds fall to the back of the last seed spoon 24 that has been successfully seeded and turned over, and the reseeding is completed. Since the reseeding operation is completed before the empty seed spoon 24 is turned over, the reseeded potatoes can stably stay on the back of the last seed spoon 24 that has been successfully seeded and turned over. After the reseeding is completed, the seed spoon 24 continues to move along the track. Although there is no seed potato in the empty seed spoon 24 when it is turned over, since the back of the previous seed spoon 24 has been replanted, a sowing effect without missing sowing is achieved as a whole.

[0028] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
