Description

Technical Field

[0001] This invention relates to the field of track roller load testing technology, specifically to an efficient method and apparatus for hybrid breeding of maize. Background Technology

[0002] Corn has a large planting area and wide distribution in China, and is one of the staple foods for people in the mountainous areas of northern and southwestern China, as well as other arid valley regions. A good corn harvest is a major issue related to food security and social stability. In recent years, due to drought and other weather conditions, coupled with the inability to irrigate corn in a timely manner, corn yields have been significantly reduced. At the same time, the rising price of phosphate fertilizer in recent years has led many farmers to apply less or no phosphate fertilizer in corn planting, which has also reduced the drought resistance of corn and reduced yields. Therefore, cultivating high-yield, high-phosphate-efficiency, and drought-resistant corn varieties is one of the important ways to solve my country's food security, resource, and environmental problems in the future. Furthermore, scientific planting methods for corn include creating a channel between planting rows to facilitate later irrigation and harvesting.

[0003] Existing artificial pollination devices cannot adjust the beating mechanism according to the height of the corn plant, which can lead to missed pollinations and reduce the success rate. This limits the effectiveness of the devices. To address these issues, the inventors propose a highly efficient method and device for hybrid corn breeding. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example: Figure 1-8 As shown, the present invention provides a technical solution: a highly efficient method for hybrid breeding of maize, comprising the following steps:

[0035] S1: First, select plants of the opposite sex and perform continuous self-pollination to serve as the male parent for corn seeds;

[0036] S2: Then, the male corn seed parent and the female corn seed parent are crossed to obtain the F1 generation seeds;

[0037] S3: Subsequently, the F1 generation seeds were self-pollinated, and after self-pollination, specific plants were selected to obtain the second female parent of maize seeds;

[0038] S4: Next, the second female parent of corn seeds is crossed with the male parent of corn seeds to obtain F2 generation seeds. Finally, the new seeds are pretreated to obtain the final high-efficiency corn seeds.

[0039] An apparatus for an efficient maize hybridization breeding method includes a base 1, a lifting component 2 fixedly connected to the top of the base 1 near the center, and an output component 3 provided at the top of the lifting component 2.

[0040] The lifting assembly 2 includes a fixed box 201, and the bottom end of the fixed box 201 is fixedly connected to the base 1. A motor 202 is fixedly connected to the side end of the fixed box 201 near the top. A connecting shaft 203 is rotatably connected between the inner walls of the fixed box 201 near the top. The output end of the motor 202 passes through the fixed box 201 and is fixedly connected to the connecting shaft 203. A rotating wheel 204 is symmetrically fixedly connected to the outer ring of the connecting shaft 203 near both sides. A toothed plate 205 is symmetrically slidably connected to the inner wall of the side end of the fixed box 201 near the rotating wheel 204.

[0041] By adopting the above technical solution, the motor 202 is operated, thereby causing the fixedly connected shaft 203 to rotate, and causing the two rotating wheels 204 fixed on the shaft 203 to rotate.

[0042] Auxiliary blocks 206 are symmetrically fixedly connected at the center of the inner walls on both sides of the fixed box 201. A base 207 is slidably connected between the two auxiliary blocks 206, and the top of the base 207 is fixedly connected to the bottom of the toothed plate 205. Hydraulic columns 208 are symmetrically fixedly connected to the top of the base 207 near both sides.

[0043] By adopting the above technical solution, when the toothed plate 205 rises, the fixedly connected base 207 rises under the action of the two auxiliary blocks 206.

[0044] The output component 3 includes a base 301, and the bottom end of the base 301 is fixedly connected to the top end of the hydraulic column 208. A fixed plate 307 is fixedly connected to the center of the top end of the base 301. A rotating plate 308 is rotatably connected to the center of the top end of the fixed plate 307. An L-column 305 is fixedly connected to the top end of the fixed plate 307 near the center. A second motor 306 is fixedly connected to the top end of the L-column 305. The output end of the second motor 306 passes through the L-column 305 and is fixedly connected to the rotating plate 308.

[0045] By adopting the above technical solution, the motor 306 is operated, which causes the fixedly connected rotating plate 308 to rotate, and the two connecting shafts 309 pull the two support plates 304 to move towards each other.

[0046] The base 301 has symmetrically opened sliding grooves 302 near the two sides at the top. Two sets of connecting plates 303 are symmetrically slidably connected inside the two sliding grooves 302. Support plates 304 are symmetrically fixedly connected to the two ends of the base 301 near the hydraulic column 208. The end of the support plate 304 near the motor 306 is fixedly connected to the connecting plate 303. The top of the two support plates 304 is rotatably connected to the top of the rotating plate 308 by a connecting shaft 309.

[0047] By adopting the above technical solution, when the two connecting shafts 309 pull the support plate 304 to move, the support plate 304 can move under the action of the two sets of connecting plates 303 and the slide groove 302.

[0048] Support plate 2 310 is symmetrically fixedly connected to the top of two support plates 304. Connecting plate 2 311 is symmetrically fixedly connected to the top of the two support plates 310 near motor 2 306. One end of connecting plate 2 311 near motor 2 306 is rotatably connected to sliding shaft 312, and sliding shaft 312 has an end groove inside. Sliding shaft 2 313 is slidably connected inside sliding shaft 312, and an end block is fixedly connected to the outer ring of sliding shaft 2 313. The other end of sliding shaft 2 313 is connected to connecting plate 2 311. The side end is rotatably connected. One of the connecting plates 311 is fixedly connected to one end of the sliding shaft 313. The bottom end of the connecting plate 316 is rotatably connected to the bevel gear 315. The top end of the connecting plate 316 is fixedly connected to the motor 317. The output end of the motor 317 passes through the connecting plate 316 and is fixedly connected to the bevel gear 315. The outer ring of the sliding shaft 313 is fixedly connected to the bevel gear 314 near the bevel gear 315, and the bevel gear 314 meshes with the bevel gear 315.

[0049] By adopting the above technical solution, when the motor 317 is running, the fixedly connected bevel gear 315 rotates, thereby driving the meshing bevel gear 314 to rotate, which in turn causes the fixedly connected sliding shafts 313 and 312 to rotate. When the two connecting plates 311 move towards each other, the sliding shaft 313 can slide into the sliding shaft 312, thereby realizing the retraction function.

[0050] Two connecting plates 311 are symmetrically rotatably connected to a sliding column 320 at the end away from the motor 306. The ends of sliding shafts 313 and 312 away from the motor 306 are fixedly connected to the sliding column 320. The tops of the two support plates 310 are symmetrically fixedly connected to a vertical plate 319 near the connecting plates 311. A sliding groove 323 is provided in the center of the vertical plate 319, and a connecting block is slidably connected inside the sliding groove 323.

[0051] By adopting the above technical solution, when the first sliding shaft 312 and the second sliding shaft 313 rotate, the two fixedly connected sliding columns 320 will rotate. The connecting block is set so that the moving block 321 can drive the top plate 325 to move up and down when it moves up and down.

[0052] A column 322 is symmetrically fixedly connected to the top of the support plate 310 near the vertical plate 319. A moving block 321 is slidably connected between the two columns 322, and the sliding column 320 and the moving block 321 are used in a sliding cooperation. One end of the moving block 321 near the vertical plate 319 is fixedly connected to the connecting block. A column 324 is symmetrically fixedly connected to the top of the support plate 310 near the other end of the vertical plate 319. A top plate 325 is slidably connected between the two columns 324, and the side end of the top plate 325 is fixedly connected to the connecting block. A mounting plate 326 is fixedly connected to the top of the top plate 325. A pressure cylinder 327 is rotatably connected to the end of the mounting plate 326 away from the motor 306 and near the top.

[0053] By adopting the above technical solution, when the sliding column 320 rotates, the cooperating moving block 321 will move up and down under the action of the two columns 322, thereby causing the top plate 325 to move up and down under the action of the two columns 324.

[0054] A synchronous pulley 328 is symmetrically rotatably connected to one end of the mounting plate 326 near the top of the motor 306. A synchronous belt 329 is connected between the two synchronous pulleys 328. One end of the pressure cylinder 327 passes through the mounting plate 326 and is fixedly connected to one of the synchronous pulleys 328. A vertical plate 330 is fixedly connected to the side of the mounting plate 326 near the synchronous pulley 328. A rotating wheel 331 is rotatably connected to the end of the vertical plate 330 away from the synchronous pulley 328. The side of the rotating wheel 331 passes through the vertical plate 330 and is fixedly connected to the synchronous pulley 328. A toothed plate 332 is fixedly connected to the side of the vertical plate 319 above the moving block 321 and near the rotating wheel 331. The toothed plate 332 meshes with the rotating wheel 331.

[0055] By adopting the above technical solution, when the top plate 325 drives the mounting plate 326 to move up and down, the rotating wheel 331 will rotate under the action of the toothed plate 332, thereby driving the two synchronous wheels 328 to rotate simultaneously under the action of the synchronous belt 329.

[0056] Working principle: When in use, the present invention first drives the motor 202 to rotate the fixedly connected shaft 203. At this time, the two toothed plates 205 move upward under the action of the two meshing wheels 204, so that the base 207 fixedly connected to the bottom of the two toothed plates 205 rises under the action of the two auxiliary blocks 206. Then, the two hydraulic columns 208 are operated at the same time, thereby raising the upper output component 3 and the pressure cylinder 327 to the working height, thus completing the purpose of raising and lowering the height of the pressure cylinder 327.

[0057] Next, the motor 306 is run, which causes the fixedly connected rotating plate 308 to rotate on the fixed plate 307. Then, under the action of the two connecting shafts 309, the two support plates 304 move to both sides under the action of the sliding groove 302 and the connecting plate 303. At this time, the sliding shaft 313 will extend and retract from the sliding shaft 312, so that the sliding shaft 312 and the sliding shaft 313 can work normally.

[0058] Then, the motor 317 is activated, which drives the fixedly connected bevel gear 315 to rotate, thereby causing the meshing bevel gear 314 to rotate. Then, under the action of the sliding shaft 312 and the sliding shaft 313, the two sliding columns 320 rotate simultaneously. Then, in cooperation with the moving block 321, the moving block 321 moves up and down reciprocally under the action of the two upright columns 322. Then, under the action of the connecting block in the sliding groove 323, the top plate 325 moves up and down under the action of the two upright columns 324. This causes the fixedly connected mounting plate 326 to drive the fixedly connected rotating wheel 331 above to move up and down. Then, under the action of the toothed plate 332 fixedly connected to the side end of the upright plate 319, the rotating wheel 331 rotates, thereby driving one of the fixedly connected synchronous pulleys 328 to rotate. Then, under the action of the synchronous belt 329, the other synchronous pulley 328 drives the fixedly connected pressure cylinder 327 to rotate, thereby realizing the work of pressing down the top of the corn through the pressure cylinder 327.
