Description

Technical Field

[0001] This invention relates to the field of corn planting technology, specifically to a corn drought-resistant planting device and planting method. Background Technology

[0002] Corn is widely distributed throughout China and is one of the country's important food, feed, and industrial crops. It ranks among the top in terms of planting area and yield. The plant is 1 to 4 meters tall, with an upright and solid stalk, distinct nodes, and well-developed aerial roots. The leaves are large, linear-lanceolate, and arranged alternately. Corn prefers a warm, sunny environment and is suitable for growing in deep, well-drained neutral or slightly acidic soil.

[0003] As an important global food and economic crop, corn has a high water requirement for growth. If drought occurs during its growth period, it can easily lead to problems such as low emergence rate, stunted plants, and reduced number of grains per ear. In severe cases, the yield can be reduced by 30%-50%. Drought-resistant planting requires a combination of measures, including variety selection, soil management, irrigation technology, and field regulation, to improve the survival rate and yield of crops in drought environments.

[0004] Current corn planting methods all use mulching, where the ground is covered with film before the seeds are sown into the soil. However, this method is not convenient for fertilizing the side of the seeds. Fertilizer equipment is needed to make holes in the film before fertilizing, which consumes a lot of labor and time, thus increasing planting costs. Summary of the Invention

[0018] A drought-resistant corn planting method includes the following steps:

[0019] S1: Connect the main support to the tractor, and then drag the front and rear film rolls to the ground;

[0020] S2: The tractor moves, driving the main support to move. The left and right slotted rings on the main support roll on the ground. The left slotted ring presses the front and rear film rolls into the soil and forms a groove. The perforating needle on the right slotted ring punches holes in the film.

[0021] S3: When the main support moves, it drives the duckbill seeder to operate, and the duckbill seeder sows corn seeds in the soil;

[0022] S4: The water pump draws water from the water tank into the water supply pipe. The water is discharged through the water supply pipe into the groove of the left slotted ring and flows into the soil through the hole punched by the hole punch.

[0023] S5: The soil covering plate scrapes the soil onto the front and rear film rolls, fixing them in place with the soil.

[0024] The present invention has the following beneficial effects:

[0025] 1. This drought-resistant corn planting device and method utilizes a left roller, a left grooved ring, a right roller, a right grooved ring, and a perforating pin to roll above the soil. The left grooved ring presses a groove into the soil, which is then fitted into the front and rear film rolls. The rolling of the right roller, right grooved ring, and perforating pin allows the pin to create holes in the surfaces of the front and rear film rolls. Water and liquid fertilizer located in the groove can then seep into the soil through these holes. This solves the problem of existing mulching methods, which are inconvenient for fertilizing the sides of the seeds and require fertilization equipment to create holes in the film, consuming significant labor and time, thus increasing planting costs.

[0026] 2. The drought-resistant corn planting device and method use a water pump to draw water from the water tank into the water supply pipe, and then discharge it through the water supply pipe. This allows the device to water the seeds at the same time as sowing, eliminating the need for farmers to water after sowing and greatly reducing labor and time.

[0027] 3. The corn drought-resistant planting device and planting method, through the setting of the left and right end face spiral blocks, since the end faces of the left and right end face spiral blocks are in a spiral state, the end faces of the left and right end face spiral blocks have the highest and lowest points. When the adjusting block rotates in the direction of the forward film roll, the elastic force of the left and right support springs pushes the left and right end face spiral blocks towards the middle, gradually causing the left and right pins to disengage from the front and rear mounting shafts. This allows the front and rear mounting shafts to be disassembled with one rotation of the device, improving the replacement efficiency of the front and rear film rolls. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0047] Please see Figures 1-12 A corn drought-resistant planting device includes a main support 1, a film covering mechanism 2 installed on the top of the main support 1, a water supply mechanism 5 on the right side of the film covering mechanism 2, a side grooving mechanism 3 at the bottom of the water supply mechanism 5, a soil covering plate 6 on the right side of the side grooving mechanism 3, and a duckbill seeder 4 on the right side of the water supply mechanism 5.

[0048] In the above structure, by connecting the main support 1 to the tractor, the tractor will drive the main support 1 forward when it moves forward. The film covering mechanism 2 on the main support 1 lays the film on the ground. Then, the side grooving mechanism 3 presses the film into the soil, creating a groove in the soil. Then, the duckbill seeder 4 sows the seeds into the soil. The side grooving mechanism 3 punches multiple holes in the film, so the water discharged by the water supply mechanism 5 can seep into the soil through these holes, keeping the soil on the side of the corn in a moist state and increasing the probability of corn germination. With the setting of the soil covering plate 6, the soil covering plate 6 can scrape the soil onto the surface of the film, so that the side of the film can be fixed by the soil, improving the stability of the device. The soil between the two films can be fixed by the middle soil covering cylinder.

[0049] The film-coating mechanism 2 includes a film mounting assembly 21, and film fixing assemblies 22 are provided at both ends of the film mounting assembly 21;

[0050] In the above structure, the film mounting component 21 is used to mount the film roll. The film mounting component 21 can support the film roll, and the film fixing component 22 can lock the film mounting component 21 so that the film mounting component 21 cannot detach from the film fixing component 22, thereby improving the stability of the device.

[0051] The film mounting assembly 21 includes a front mounting shaft 2101, a rear mounting shaft 2106 is provided on the right side of the front mounting shaft 2101, a front film roll 2111 is movably sleeved at the rear end of the front mounting shaft 2101, and a rear film roll 2112 is movably sleeved at the front end of the rear mounting shaft 2106.

[0052] In the above structure, by mounting the front mounting shaft 2101 and the rear mounting shaft 2106 on the film fixing assembly 22, the front film roll 2111 is sleeved on the front mounting shaft 2101 and the rear film roll 2112 is sleeved on the rear mounting shaft 2106. The front film roll 2111 can rotate on the front mounting shaft 2101 and the rear film roll 2112 can rotate on the rear mounting shaft 2106. At this time, the front mounting shaft 2101 and the rear mounting shaft 2106 are stationary. Therefore, when the main support 1 moves, the front film roll 2111 and the rear film roll 2112 can cover the ground.

[0053] The side grooving mechanism 3 includes a secondary support 301, which is mounted on the main support 1. The soil covering plate 6 is mounted on the secondary support 301. A left connecting block 302 is mounted on the outer wall of the secondary support 301. A left roller 303 is movably connected to the outer edge of the left connecting block 302. A left grooving ring 304 is fixedly mounted on the outer wall of the left roller 303. A right connecting block 305 is provided on the right side of the left connecting block 302. A right roller 306 is movably connected to the outer edge of the right connecting block 305. A right grooving ring 307 is fixedly mounted on the outer wall of the right roller 306. A number of perforating pins 308 are mounted on the outer wall of the right grooving ring 307. The number of perforating pins 308 is evenly distributed on the right grooving ring 307.

[0054] In the above structure, the left roller 303, left grooved ring 304, right roller 306, right grooved ring 307, and perforating pin 308 roll above the soil. The left grooved ring 304 can press a groove into the soil. At this time, the front film roll 2111 and the rear film roll 2112 are in contact with this groove. The front film roll 2111 and the rear film roll 2112 act as a barrier in this groove, preventing the loss of water and liquid fertilizer. Water and liquid fertilizer can be retained in the groove. Then, the right roller 306, right grooved ring 307, and perforating pin 308 roll the soil. The rolling of the 08-shaped opening needle 308 allows it to create openings on the surfaces of the front film roll 2111 and the rear film roll 2112. Water and liquid fertilizer located in the grooves can then seep into the soil through these openings, enabling side-watering and fertilization, protecting the root system, promoting deep and widespread root development, and enhancing absorption capacity. This improves water and fertilizer utilization, reduces waste and pollution, lowers disease risk, and minimizes potential field management problems. It also adapts to the different growth stages of corn, increasing yield and quality. Furthermore, the front film roll 2111 and the rear film roll 2112 cover the ground, making it difficult for the water that has seeped into the soil to evaporate, thus greatly improving the corn's drought resistance.

[0055] In a preferred embodiment: a front stop plate 2104 is fixedly mounted on the outer edge of the front mounting shaft 2101, and a front handle 2105 is fixedly mounted on the top of the front stop plate 2104; a rear stop plate 2109 is fixedly mounted on the outer edge of the rear mounting shaft 2106, and a rear handle 2110 is fixedly mounted on the top of the rear stop plate 2109.

[0056] In the above structure, the front blocking disc 2104 can block and position the front film roll 2111, so that the front film roll 2111 is located at the front end of the front mounting shaft 2101 and the rear film roll 2112 is located at the rear end of the rear mounting shaft 2106. At this time, the head of the front film roll 2111 and the tail of the rear film roll 2112 will overlap. When the left slotted ring 304 presses the film into the soil, the two sides of the film will move towards the groove. Therefore, the front film roll 2111... The front and rear film rolls 2111 and 2112 need to be overlapped so that there are no gaps after the front and rear film rolls 2111 and 2112 are laid. This prevents moisture in the soil from evaporating from the gaps and improves the rationality of the device. With the front handle 2105 and the rear handle 2110, the front mounting shaft 2101 and the front film roll 2111 can be removed from the main support 1 by holding the front handle 2105, making it easy to remove and unload the front film roll 2111 and the rear film roll 2112 on this device.

[0057] In a preferred embodiment: front positioning blocks 2102 are installed at both ends of the front mounting shaft 2101, and front positioning holes 2103 are provided on the outer edge of the front positioning blocks 2102; rear positioning blocks 2107 are fixedly installed at both ends of the rear mounting shaft 2106, and rear positioning holes 2108 are provided on the outer edge of the rear positioning blocks 2107.

[0058] In the above structure, through the cooperation of the front mounting shaft 2101 and the left positioning shell 2201, the front mounting shaft 2101 can be inserted into the left positioning shell 2201, and the left positioning shell 2201 positions the front mounting shaft 2101 so that the front mounting shaft 2101 cannot rotate. The rear mounting shaft 2106 can be inserted into the right positioning shell 2202, and the right positioning shell 2202 positions the rear mounting shaft 2106 so that the rear mounting shaft 2106 cannot rotate, thus improving the rationality of the device.

[0059] In a preferred embodiment: the film fixing assembly 22 includes a left positioning shell 2201, and a right positioning shell 2202 is provided on the right side of the left positioning shell 2201. The outer walls of the left positioning shell 2201 and the right positioning shell 2202 are respectively fixedly assembled with a left limiting cylinder 2203 and a right limiting cylinder 2204. The inner walls of the left limiting cylinder 2203 and the right limiting cylinder 2204 are respectively slidably connected with a left pin 2205 and a right pin 2206.

[0060] In the above structure, the front mounting shaft 2101 located in the left positioning housing 2201 can be fixed by the left pin 2205 through the setting of the left pin 2205 and the right pin 2206. The left pin 2205 passes through the left positioning housing 2201 and enters the front positioning hole 2103 on the front mounting shaft 2101, so that the front mounting shaft 2101 can be locked. The rear mounting shaft 2106 located in the right positioning housing 2202 can be fixed by the right pin 2206 through the right positioning housing 2202 and enters the rear positioning hole 2108 on the rear mounting shaft 2106, so that the rear mounting shaft 2106 can be locked.

[0061] In a preferred embodiment: a left end face spiral block 2207 is fixedly mounted on the end of the left pin 2205 away from the left positioning shell 2201, a right end face spiral block 2208 is fixedly mounted on the end of the right pin 2206 away from the right positioning shell 2202, a left support spring 2209 is provided between the left end face spiral block 2207 and the left limiting cylinder 2203, and a right support spring 2210 is provided between the right end face spiral block 2208 and the right limiting cylinder 2204.

[0062] In the above structure, by setting the left end face spiral block 2207 and the right end face spiral block 2208, since the end faces of the left end face spiral block 2207 and the right end face spiral block 2208 are in a spiral state, the end faces of the left end face spiral block 2207 and the right end face spiral block 2208 have the highest point and the lowest point. When the adjusting block 2213 rotates in the direction of the forward film roll 2111, the elastic force of the left support spring 2209 and the right support spring 2210 can push the left end face spiral block 2207 and the right end face spiral block 2208 towards the middle respectively, so that the left pin 2205 and the right pin 2206 are disengaged from the front mounting shaft 2101 and the rear mounting shaft 2106. This allows the device to disassemble the front mounting shaft 2101 and the rear mounting shaft 2106 with one rotation, improving the disassembly and fixing efficiency.

[0063] In a preferred embodiment: an adjusting block 2213 is provided between the left end face spiral block 2207 and the right end face spiral block 2208. The inner cavities at both ends of the adjusting block 2213 are respectively equipped with a left roller 2214 and a right roller 2215. A handle 2216 is fixedly mounted on the outer wall of the adjusting block 2213.

[0064] In the above structure, through the setting of the left roller 2214 and the right roller 2215, the left roller 2214 and the right roller 2215 respectively contact the left end face spiral block 2207 and the right end face spiral block 2208. When the adjusting block 2213 rotates, it will drive the left roller 2214 and the right roller 2215 to rotate, gradually making the left roller 2214 and the right roller 2215 rotate to the lowest point of the end face of the left end face spiral block 2207 and the right end face spiral block 2208. When disassembling, the adjusting block 2213 can be rotated by holding the handle 2216.

[0065] In a preferred embodiment: anti-detachment grooves 2211 are provided at the highest points of the left end face spiral block 2207 and the right end face spiral block 2208, and limit pieces 2212 are installed at the highest points of the left end face spiral block 2207 and the right end face spiral block 2208.

[0066] In the above structure, the anti-detachment groove 2211 on the left end face spiral block 2207 and the right end face spiral block 2208 can limit the left roller 2214 and the right roller 2215, so that the vibration generated when the equipment moves cannot cause the adjusting block 2213 to rotate. The limiting piece 2212 can block the adjusting block 2213, preventing the adjusting block 2213 from detaching from the highest point of the left end face spiral block 2207 and the right end face spiral block 2208, thus improving the stability of the device.

[0067] In a preferred embodiment: the water supply mechanism 5 includes a water tank 501, a water pump 502 is fixedly mounted on the bottom of the water tank 501, a water supply pipe 503 is installed at the outlet of the water pump 502, and the water supply pipe 503 is mounted on the main support 1.

[0068] In the above structure, the water in the water tank 501 is drawn into the water supply pipe 503 by the operation of the water pump 502, and then discharged through the water supply pipe 503. This allows the device to treat the seeds with water at the same time as sowing, so that farmers do not need to water after sowing, which greatly reduces labor and time.

[0069] In a preferred embodiment: the outlet of the water supply pipe 503 is located to the right of the right slotted ring 307, and the water supply pipe 503 and the right slotted ring 307 are on the same vertical line.

[0070] In the above structure, by placing the water supply pipe 503 above the right slotted ring 307, the outlet of the water supply pipe 503 corresponds exactly to the groove after the right slotted ring 307 has been rolled. Therefore, the water discharged from the water supply pipe 503 flows into the groove, and then the water in the groove flows into the soil through the hole pierced by the hole-opening needle 308, so that the soil is wetted.

[0071] A drought-resistant corn planting method includes the following steps:

[0072] S1: Connect the main support 1 to the tractor, and then drag the front film roll 2111 and the rear film roll 2112 to the ground;

[0073] S2: The tractor moves, driving the main support 1 to move. The left slotted ring 304 and the right slotted ring 307 on the main support 1 roll on the ground. The left slotted ring 304 presses the front film roll 2111 and the rear film roll 2112 into the soil and forms a groove. The perforating needle 308 on the right slotted ring 307 punches holes in the film.

[0074] S3: When the main support 1 moves, it drives the duckbill seeder 4 to run, and the duckbill seeder 4 sows corn seeds in the soil;

[0075] S4: Water pump 502 draws water from water tank 501 into water supply pipe 503. The water is discharged through water supply pipe 503 into the groove crushed by left slotted ring 304. The water flows into the soil through the hole punched by hole needle 308.

[0076] S5: The soil covering plate 6 scrapes the soil onto the front film roll 2111 and the rear film roll 2112, so that the front film roll 2111 and the rear film roll 2112 are fixed by the soil.

[0077] Working principle: During use, the main support 1 is connected to the tractor. The movement of the tractor drives the main support 1 to move on the ground. At this time, the front film roll 2111 and the rear film roll 2112 come into contact with the ground. Subsequently, the left roller 303 and the right roller 306 pass through and come into contact with the front film roll 2111 and the rear film roll 2112. The left grooved ring 304 on the left roller 303 presses the soil into a groove. At this time, the front film roll 2111 and the rear film roll 2112 adhere to the groove. The right roller 306, the right grooved ring 307, and the perforating needle 308 then pass through this groove. The perforating needle 308 can puncture holes in the surface of the front film roll 2111 and the rear film roll 2112 through the groove. The movement of the main support 1 drives the duckbill seeder 4 to operate, making... Corn seeds in the duckbill seeder 4 are sown in the soil. Simultaneously, water pump 502 draws water from water tank 501 into water supply pipe 503. Water discharged from water supply pipe 503 flows into a groove, which seeps into the soil through holes, moistening the soil. This groove can be reused repeatedly during the corn's growth stage. Liquid fertilizer can be added to the groove, allowing it to seep into the soil for the corn to absorb. When the front film roll 2111 and rear film roll 2112 are used up, the handle 2216 is rotated towards the front and rear film rolls 2111 and 2112 respectively. At this time, the left roller 2214 and right roller 2215 rotate on the end faces of the left and right end face spiral blocks 2207 and 2208. The movement gradually rotates the left roller 2214 and right roller 2215 to the lowest point of the end faces of the left end face spiral block 2207 and right end face spiral block 2208. At this time, the left end face spiral block 2207 and left pin 2205, and the right pin 2206 and right end face spiral block 2208 move towards the center.
