Description

Technical Field

[0001] The present invention belongs to the technical field of grain planting and cultivation, and in particular relates to a grain crop planting and cultivation device and method. Background Art

[0002] Food crops mainly include three categories: cereal crops, legume crops and tuber crops; Cereal crops: mainly include rice (japonica rice, indica rice, glutinous rice, etc.), wheat, barley, oats, corn, sorghum, millet, highland barley, etc. Among them, wheat, rice, and corn are known as the world's three major food crops; Legume crops: mainly include soybeans, adzuki beans (red beans), mung beans, broad beans, peas, etc.; Tuber crops: mainly include sweet potatoes, potatoes, cassava, sweet potatoes (sweet potatoes, purple potatoes, yellow potatoes, white potatoes, etc.), etc. These food crops are an important part of human diet and agricultural production; At present, when farmers plant corn crops on smaller lands, they generally use hoes to dig the land into channels, and then manually sow corn seeds and bury the channels. This planting method is inefficient and labor-intensive, and the sowing depth is not uniform enough. Appropriate sowing depth is crucial to the growth of corn. Sowing too deep will lead to a long germination time, high nutrient consumption, and weak seedlings. Sowing too shallowly will easily cause the seeds to be dried by the wind and fail to germinate.

When the passively rotating pipe passes through the L-shaped groove plate, the longer plate installed inside it will contact and press against the L-shaped groove plate, causing it to slide in the arc plate groove under force, and at the same time drive the turntable to rotate in the disc groove. The rotating turntable will also drive multiple T-shaped rods to slide in the arc groove, so that each T-shaped rod drives the corresponding baffle to diffuse, and no longer blocks the bottom end of the casing, so that it can release the corn kernels that enter the pipe during the rotation of the roller barrel, thereby realizing the feeding and planting operation in the soil pit directly below.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention manually pushes the slide frame to move on the ground, and simultaneously starts the forward and reverse rotating motor on the slide frame to drive the rotating rod and the roller drum to rotate synchronously, so that the corn kernels entering the roller drum through the feeding hopper can be screened, and the rotation of the roller drum can make the corn kernels in the roller drum fully and repeatedly contact the screen drum, thereby screening some unqualified kernels that may exist in the corn kernels and make them enter the screen drum, and the passive rotation of the roller drum can synchronously drive the pipe and the digging shovel to rotate, and then the rotating digging shovel can dig a plurality of uniform deep pits in the ground, thereby avoiding the situation where the soil pits dug manually have different depths and sizes; The present invention uses a passively rotating pipe. When passing through the L-shaped groove plate, the longer plate body paddle installed inside it will contact and press against the L-shaped groove plate, thereby being forced to slide in the arc plate groove, and at the same time, it will drive the turntable to rotate in the disc groove, and the turntable will drive another shorter paddle to slide in the corresponding arc plate groove in the same direction. The rotating turntable will also drive multiple T-shaped rods to slide in the arc groove, and the sliding process will be limited and guided by the corresponding rectangular groove plate, so that each T-shaped rod drives the corresponding baffle to spread, and the bottom end of the sleeve is no longer blocked, so that the corn kernels entering the pipe during the rotation of the roller barrel can be released, thereby realizing the feeding and planting operation in the soil pit directly below; When the paddle plate of the long plate body is not under force, the paddle plate of the short plate body can no longer push the sleeve plate, so that the sliding rod and the two support plates on the sleeve plate are driven by the corresponding torsion springs to reset, and the turntable is driven to reset, thereby indirectly driving the baffle to seal the bottom end of the sleeve again. At the same time, driven by the slide frame, the inclined plate frame and the groove push plate are synchronously translated, thereby pushing the accumulated soil on the ground, burying the soil pits with corn kernels in turn, and avoiding the work of manually sealing the pits.

An L-shaped groove plate 23 is fixedly connected to the inner wall of the other end of the slide frame 1, and the rod body of the rotating rod 22 is also rotatably connected to the plate body of the L-shaped groove plate 23. The other end plate of the rolling barrel 12 is also threadedly connected to the feeding hopper 24. The bottom end rod body of each T-shaped rod 29 is fixedly connected to a baffle 232. The top of each baffle 232 is fitted and slidably connected to the bottom end of the sleeve 231. The outer walls on both sides of the bottom end of the turntable 27 are also fixedly connected to the dial plates 233. The two selector plates 233 are specifically one long and one short. Both ends of the pipe 25 are provided with arc plate grooves that can be fitted and slidably connected to the two selector plates 233. A rectangular groove plate 234 is fixedly connected to the outer wall of one end of the pipe 25. The rectangular groove plate 234 is provided with a rectangular groove that can intermittently fit and slide with the plate body of the shorter selector plate 233. The longer selector plate 233 can intermittently fit and slide with the L-shaped groove plate 23. A sliding rod 235 is rotatably connected to the inner wall of the rectangular groove plate 234. A sleeve plate 236 is fixedly connected to the rod body of the sliding rod 235. The sleeve plate 236 is fitted and slidably connected to the plate body of the shorter selector plate 233.

[0021] The above scheme is adopted: when the passively rotating pipe 25 passes through the L-shaped groove plate 23, the longer plate body dial 233 installed inside it will contact and press against the L-shaped groove plate 23, thereby being forced to slide in the arc plate groove, and at the same time, it will drive the turntable 27 to rotate in the disc groove, and make the turntable 27 drive another shorter dial 233 to slide in the corresponding arc plate groove in the same direction. The rotating turntable 27 will also drive multiple T-shaped rods 29 to slide in the arc groove 28, and the sliding process will be limited and guided by the corresponding rectangular groove plate 230, so that each T-shaped rod 29 drives the corresponding baffle 232 to diffuse, and no longer blocks the bottom end pipe mouth of the sleeve 231, so that it can release the corn kernels entering the pipe 25 during the rotation of the roller barrel 12, thereby realizing the feeding and planting operation in the soil pit directly below.

[0022] The upper and lower rod bodies of the sliding rod 235 are also fixedly connected with support plates 237, and the outer walls of one end of the two support plates 237 and the upper and lower inner walls of the rectangular groove plate 234 are jointly and fixedly connected with torsion springs 238.

[0023] The above solution is adopted: when the paddle plate 233 of the long plate body is not under force, the paddle plate 233 of the short plate body can no longer push the sleeve plate 236, so that the slide rod 235 and the two support plates 237 on the sleeve plate 236 will be driven by the corresponding torsion spring 238 to reset, and the turntable 27 will be driven to reset, thereby indirectly driving the baffle 232 to seal the bottom end pipe mouth of the sleeve 231 again. At the same time, driven by the slide frame 1, the inclined plate frame 239 and the groove push plate 240 will be synchronously translated, thereby pushing the accumulated soil on the ground, burying the soil pits with corn kernels in turn, and avoiding the work of manually sealing the pits.

[0024] One point that needs to be added is that the feeding hopper 24 will be screw-rotated and installed on the roller barrel 12 only when feeding the roller barrel 12, and it will be blocked manually using a plug plate at all times.

[0025] A method for planting and cultivating grain crops, the specific operation steps are as follows: S1. By starting the forward and reverse rotation motor 21 on the slide frame 1, the rotating rod 22 and the roller drum 12 are driven to rotate synchronously, so that the corn kernels entering the roller drum 12 through the feeding hopper 24 can be screened. In addition, as the roller drum 12 rotates, the corn kernels in the roller drum 12 are fully and repeatedly contacted with the screen drum 13, thereby screening out some unqualified kernels that may be present in the corn kernels; S2. The passive rotation of the roller 12 will synchronously drive the pipe 25 and the shovel 26 to rotate, and then the rotating shovel 26 will dig a plurality of uniform deep pits in the soil, avoiding the situation where the soil pits dug manually have different depths and sizes; S3. When the passively rotating pipe 25 passes through the L-shaped groove plate 23, the longer plate plate 233 installed inside it will contact and press against the L-shaped groove plate 23, thereby being forced to slide in the arc plate groove, and at the same time, it will drive the turntable 27 to rotate in the disc groove. The rotating turntable 27 will also drive multiple T-shaped rods 29 to slide in the arc groove 28, so that each T-shaped rod 29 drives the corresponding baffle 232 to diffuse, and no longer blocks the bottom end of the sleeve 231, so that it can release the corn kernels that enter the pipe 25 during the rotation of the roller barrel 12, thereby realizing the feeding and planting operation in the soil pit directly below.

[0026] The working principle and use process of the present invention are as follows: the slide frame 1 is manually pushed to move on the ground, and the forward and reverse rotating motor 21 on the slide frame 1 is started at the same time, driving the rotating rod 22 and the roller drum 12 to rotate synchronously, so that the corn kernels entering the roller drum 12 through the feeding hopper 24 can be screened, and under the rotation of the roller drum 12, the corn kernels in the roller drum 12 will fully and repeatedly contact the screen drum 13, thereby screening some unqualified grains that may exist in the corn kernels and make them enter the screen drum 13, and under the passive rotation of the roller drum 12, the pipe 25 and the shovel 26 will be synchronously driven to rotate, and then the rotating shovel 26 will dig a plurality of uniform deep pits in the ground, avoiding the situation that the soil pits dug by manual labor have different depths and sizes. When the rotating pipe 25 passes through the L-shaped groove plate 23, the longer plate body dial plate 233 installed inside it will contact and press against the L-shaped groove plate 23, thereby being forced to slide in the arc plate groove, and at the same time, it will drive the turntable 27 to rotate in the disc groove, and the turntable 27 will drive another shorter dial plate 233 to slide in the corresponding arc plate groove in the same direction. The rotating turntable 27 will also drive multiple T-shaped rods 29 to slide in the arc groove 28, and the sliding process will be limited and guided by the corresponding rectangular groove plate 230, so that each T-shaped rod 29 drives the corresponding baffle 232 to spread, and no longer blocks the bottom end of the sleeve 231, so that it can put the corn kernels entering the pipe 25 during the rotation of the roller barrel 12, thereby realizing the feeding and planting operation in the soil pit directly below; Then, when the long plate's paddle plate 233 is not under force, the short plate's paddle plate 233 can no longer push the sleeve plate 236, so that the slide bar 235 and the two support plates 237 on the sleeve plate 236 will be driven by the corresponding torsion spring 238 to reset, driving the turntable 27 to reset, thereby indirectly driving the baffle 232 to seal the bottom end pipe opening of the sleeve 231 again. At the same time, driven by the slide frame 1, the inclined plate frame 239 and the groove push plate 240 will be synchronously translated, thereby pushing the accumulated soil on the ground, burying the soil pits with corn kernels in turn, avoiding the work of manually sealing the pits, and the unqualified grains that may exist in the screen drum 13 can be cleaned at one time by removing the plug plate 14.
