Description

Technical Field

[0001] This utility model relates to the field of potato cultivation, and in particular to a potato experimental planter. Background Technology

[0002] The scientific name for potato is Solanum tuberosum. China is the world's largest producer of potatoes. Potato growth begins with the sprouting of buds from the tuber. Only after the tuber breaks dormancy will there be noticeable growth of buds and seedlings. The period from bud sprouting to seedling emergence is the germination period, during which the first segment of the main stem grows. The focus of growth during the germination period is on bud elongation, root development, and the formation of stolons. Nutrients and water are mainly supplied by the seed potato, in the order of stems, leaves, and roots. The speed and quality of growth are determined by the seed potato and the environmental conditions required for germination.

[0003] For example, patent document CN219555633U discloses a potato experimental planter, including a seed block bin and a support frame. A guide plate is installed on one side of the seed block bin, and a rotary disc is installed below the guide plate. A feeding port is located below the rotary disc, and a conveyor belt shell is welded to the outer side below the feeding port. This invention utilizes a rotary disc, guide plate, and conveyor belt, which not only prevents potato blockage but also controls the feeding process. Evenly spaced partitions are installed on the surface of the conveyor belt, and the distance between the partitions controls the planting distance of the potato seed blocks, increasing the survival rate. A fertilizer bin and fertilizer feeding roller can spread fertilizer during planting, and the fertilizer feeding roller ensures more even fertilizer application. Connecting rods and axle pins allow the entire fertilizer spreading device to be easily disassembled when not in use, reducing the burden on the machine during operation.

[0004] In existing technologies, to test the yield and disease resistance of potato seeds, experimental planting is required in experimental fields. According to the principle of controlled variables in experiments, the size of potato seeds in the same area should be roughly the same, while the size of potato seeds in different areas should be significantly different. To facilitate potato planting for experiments, a potato planter with sorting function has been proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

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

[0030] like Figures 1-8As shown, a potato experimental planter includes a main body with a planting mechanism. The main body includes a mobile frame 101, a traction frame 102 welded to the upper front end of the mobile frame 101, and two symmetrically arranged wheels 103 rotatably connected to bearings on both sides of the mobile frame 101. A plowing assembly is located on the front of the mobile frame 101, and a soil covering assembly is located on the rear of the mobile frame 101. A sorting mechanism is mounted on the mobile frame 101, including a sorting box 201 bolted to the top of the mobile frame 101. Several bearings rotatably connect to the top of the sorting box 201. A sorting roller 202 is inclined and evenly arranged, gradually narrowing from top to bottom. A feeding mechanism is provided at the top of the sorting box 201. A transmission component for driving the sorting roller 202 is provided at the front of the sorting box 201. A feeding bin 206 is welded and fixedly connected inside the sorting box 201. The upper end of the feeding bin 206 is shaped like an inverted triangle. Two symmetrically arranged telescopic plates 207 are hinged to the top of the feeding bin 206. Limiting components are provided on the telescopic plates 207. The bottom of the feeding bin 206 is fixedly connected to the seeding mechanism. A recycling bin 210 is fixedly connected to the rear of the sorting box 201. An arc-shaped plate 211 is fixedly connected to the front side of 206. To test the yield and disease resistance of potato seeds, experimental planting is required in an experimental field. According to the principle of controlled variables in the experiment, the size of potato seeds in the same area should be approximately equal, while the size of potato seeds in different areas should be significantly different. To facilitate potato planting for experimental purposes, a potato planter with a sorting function is proposed. Before planting, the planter connects the device to the traction machine via the traction frame 102. The planter puts a large number of potato seeds into the feeding hopper 401, and then the traction machine drives the moving frame 101. During the movement, the wheel 103 rotates, the plowing component opens a furrow on the ground for planting, and the soil covering component fills the furrow with the surrounding soil after planting. The feeding mechanism pours a large number of potato seeds onto several sorting rollers 202, and the gaps between the sorting rollers 202 gradually increase. When the potato seeds move to a certain position on the sorting rollers 202, they fall into the feeding bin 206. By adjusting the position of the telescopic plate 207, potato seeds within any diameter range can be planted by the planter. This ensures that the potato seeds in the same area are of consistent size, thereby ensuring the accuracy of the planting experiment results.

[0031] The limiting assembly includes a traction shaft 208 rotatably connected to the telescopic plate 207. A sliding groove is provided on the sorting box 201, and a scale is provided around the sliding groove. The traction shaft 208 is slidably connected to the sliding groove on the sorting box 201. The traction shaft 208 extends to the outside of the sorting box 201. A friction plate is bolted to one end of the traction shaft 208, and the friction plate contacts the outer wall of the sorting box 201. A limiting nut 209 is threaded to the other end of the traction shaft 208. The limiting nut 209 can contact the other side of the sorting box 201. Before planting, the planting personnel confirm the required potato seed diameter range, and then loosen the limiting nut 209. This allows the traction shaft 208 to be adjusted, thereby driving the telescopic plate 207 to move. After the traction shaft 208 is moved to the position, the limiting nut 209 is tightened. Through the combined action of the limiting nut 209 and the friction plate on the traction shaft 208, the telescopic plate 207 cannot move.

[0032] The plowing assembly includes a plowing bracket 104 fixedly connected to the front of the mobile frame 101. A plowing slide bar 105 is pinned to the plowing bracket 104, and a plow head 106 is fixedly connected to the bottom of the plowing slide bar 105. The soil covering assembly includes two soil covering brackets 107 pinned to the rear of the mobile frame 101. A soil covering slide bar 108 is pinned to the soil covering bracket 107, and a soil covering wheel 109 is rotatably connected to the bottom of the soil covering slide bar 108. After pulling out the pin on the plowing bracket 104, the position of the plowing slide bar 105 can be adjusted, thereby adjusting the depth of the plow head 106 in the soil, thus controlling the furrowing depth. Pulling out the pin on the soil covering bracket 107 allows the position of the soil covering wheel 109 to be freely adjusted, thus allowing the position of the soil covering wheel 109 to be adjusted according to the furrowing depth.

[0033] The sowing mechanism includes a sowing chamber 301 bolted to the feeding hopper 206, and the sowing chamber 301 bolted to the mobile frame 101. A sowing pipe 302 is welded to the bottom of the sowing chamber 301. A sowing turntable 306 is rotatably connected inside the sowing chamber 301. A third bevel gear 304 is fixedly connected to the top of the sowing turntable 306. A sowing drive shaft 303 is rotatably connected to the top of the sowing chamber 301. A fourth bevel gear 305 is fixedly connected to the sowing drive shaft 303, meshing with the third bevel gear 304. One end of the sowing drive shaft 303 is connected to the vehicle frame 101. Wheel 103 is connected by a chain and sprocket. As wheel 103 rotates, it drives the sowing drive shaft 303 to rotate. The sowing drive shaft 303 drives the fourth bevel gear 305 to rotate. The fourth bevel gear 305 drives the third bevel gear 304 to rotate. The third bevel gear 304 drives the sowing turntable 306 to rotate. The sorted potato seeds fall from the feeding bin 206 into the sowing bin 301. Then, as the sowing turntable 306 rotates, the seeds enter the groove on it. After the sowing turntable 306 rotates to the other side, the seeds leave the device from the sowing tube 302 and fall into the furrow, thus completing the sowing.

[0034] The transmission assembly includes a sorting drive shaft 205 rotatably connected to the front side of the sorting box 201. Several second bevel gears 204 are fixedly connected to the sorting drive shaft 205. A first bevel gear 203 is fixedly connected to one end of the sorting roller 202. The first bevel gear 203 meshes with the second bevel gears 204. One end of the sorting drive shaft 205 is connected to the other end of the seeding drive shaft 303 via a chain and sprocket. The seeding drive shaft 303 drives the sorting drive shaft 205 to rotate. The sorting drive shaft 205 drives the second bevel gears 204 to rotate. The second bevel gears 204 drive the first bevel gears 203 to rotate. The first bevel gears 203 drive the sorting roller 202 to rotate. The rotation of the sorting roller 202 can improve the sorting efficiency.

[0035] The feeding mechanism includes a feeding bracket 402 fixedly connected to the sorting box 201. A feeding hopper 401 is fixedly connected to the feeding bracket 402. A feeding drive shaft 403 is rotatably connected to the feeding hopper 401. Several circumferentially evenly arranged flaps 404 are fixedly connected to the feeding drive shaft 403. One end of the feeding drive shaft 403 is connected to the other end of the sorting drive shaft 205 via a chain and sprocket. The sorting roller 202 drives the feeding drive shaft 403 to rotate, which in turn drives the flaps 404 to rotate. The rotation of the flaps 404 causes some potato seeds to fall onto the sorting roller 202. The flaps 404 are designed to ensure that a large number of potato seeds do not fall onto the sorting roller 202 at the same time, thus preventing missed selection.

[0036] Working principle:

[0037] S1: Before sowing, the sowing personnel connect the device to the traction machine via the traction frame 102, adjust the position of the plow head 106 and the soil covering wheel 109 via the pin shaft, and then put a large number of potato seeds into the feeding hopper 401. After that, the sowing personnel confirm the required potato seed diameter range, and then loosen the limit nut 209. This allows the traction shaft 208 to be adjusted, thereby driving the telescopic plate 207 to move. After the traction shaft 208 is moved to the position, the limit nut 209 is tightened. Through the combined action of the limit nut 209 and the friction plate on the traction shaft 208, the telescopic plate 207 cannot move, thus ensuring that only potato seeds of the target size can fall into the feeding bin 206.

[0038] S2: The tractor-driven agricultural machinery moves the mobile frame 101. During this process, the wheels 103 rotate, and the plowing component opens a furrow on the ground for sowing. After sowing, the covering component fills the furrow with the surrounding soil. As the wheels 103 rotate, they drive the sowing drive shaft 303 to rotate, which in turn drives the sorting drive shaft 205 to rotate. The sorting drive shaft 205 then drives the feeding drive shaft 403, which in turn drives the sorting roller 202 to rotate. The feeding drive shaft 403 then drives the flip plate 404 to rotate, causing some potato seeds to fall onto the sorting roller 202. The gaps between the sorting rollers 202 gradually increase, so that when the potato seeds move to a certain position on the sorting roller 202, they fall into the feeding bin 206. The sowing drive shaft 303 drives the sorting drive shaft 205 to rotate, the sorting drive shaft 205 drives the second bevel gear 204 to rotate, the second bevel gear 204 drives the first bevel gear 203 to rotate, the first bevel gear 203 drives the sorting roller 202 to rotate, and the rotation of the sorting roller 202 can improve the sorting efficiency. The sowing drive shaft 303 drives the fourth bevel gear 305 to rotate, the fourth bevel gear 305 drives the third bevel gear 304 to rotate, and the third bevel gear 304 drives the sowing turntable 306 to rotate. The sorted potato seeds fall from the feeding bin 206 into the sowing bin 301, and then enter the groove on the sowing turntable 306 during its rotation. After the sowing turntable 306 rotates to the other side, it leaves the device from the sowing tube 302 and falls into the ditch, thus completing the sowing.

[0039] 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.
