Description

Technical Field

[0001] This invention relates to the field of agricultural sowing technology, specifically to a smart agricultural rotary tillage and fertilizer integrated machine. Background Technology

[0002] Smart agriculture rotary tillage and fertilizer integration machine is a compound intelligent agricultural machine that integrates rotary tillage, precision fertilization and sowing functions. It is usually equipped with positioning, Internet of Things monitoring and automatic closed-loop control modules, which can realize integrated tillage, sowing and fertilization and data management of the operation process. Intercropping and relay cropping is an efficient farming mode in which two or more different crops are planted in the same plot at the same time or in the same season. Typical modes include intercropping and relay cropping of gramineous and leguminous crops such as corn and soybeans, corn and peanuts, which can significantly improve land utilization and comprehensive productivity.

[0003] While existing smart agricultural rotary tillage and fertilizer integrated machines can complete the rotary tillage and unified fertilization of a plot in one go, there are significant differences in the requirements for row spacing, plant spacing and plant-row configuration for different crops when intercropping. The sowing mechanism of existing equipment is mostly a single fixed row spacing or equal row spacing arrangement, which makes it difficult to complete the intercropping sowing of crops simultaneously in one pass. Different crops need to be sown separately in batches, resulting in a relatively cumbersome operation process and low operation efficiency, which is not conducive to efficient operation in the intercropping mode. Summary of the Invention

[0004] The purpose of this invention is to provide a smart agriculture rotary tillage and fertilizer integrated machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A smart agriculture rotary tiller for planting and fertilizing includes a rotary tiller module, which is equipped with a sowing module. The rotary tiller module includes a frame, a rotary tiller frame rotatably connected inside the frame, a transmission box rotatably connected to the rotary tiller frame inside the frame, connecting frames on both sides of the frame, and an outer frame for each connecting frame. A leveling cylinder is rotatably connected to the frame. The sowing module includes a fertilizer box, a seed box, and a positioning frame. The fertilizer box and seed box are fixedly connected inside the frame, and the positioning frame is slidably disposed inside the frame. Several limiting seats are fixedly connected inside the frame and slidably connected to the positioning frame. Several feeding boxes are provided at the bottom of both the fertilizer box and the seed box, and the feeding boxes are connected to feeding pipes. Several partitions are fixedly connected inside both the fertilizer box and the seed box, which divide the interior of the fertilizer box and the seed box into several storage spaces. A separating block is rotatably connected to the feeding box, and the separating block has several separating grooves. The separating block is fixedly connected to a connecting shaft, and rectangular blocks are fixedly connected to both ends of the connecting shaft. A linkage module is set between two adjacent rectangular blocks. The linkage module includes two linkage frames, which are slidably connected to the adjacent rectangular blocks. Several connecting bolts are set in the two linkage frames. Several seeding legs are set in the positioning frame. The feeding pipe is connected to the adjacent seeding legs. The seeding legs are located between the rotary tiller and the leveling cylinder. The seeding legs are divided into two rows. One row of seeding legs is connected to the feeding pipe at the bottom of the fertilizer box, while the other row of seeding legs is connected to the feeding pipe at the bottom of the seed box. The positioning frame is located between the two rows of seeding legs.

[0006] Furthermore, there are two drive shafts rotatably connected inside the outer frame. The drive shafts are equipped with sprockets, and the two sprockets are connected by a chain drive. There are two rotating shafts rotatably connected inside the connecting frame. The rotating shafts are fixedly connected to the adjacent connecting shafts. The rotating shafts are equipped with drive wheels, and the two drive wheels are connected by a drive belt. One drive shaft is fixedly connected to the end of one rotating shaft, and the other drive shaft is connected to the transmission box.

[0007] Furthermore, the drive shaft is slidably connected to a limit ring, the limit ring is provided with a positioning screw that is screwed into the drive shaft, the sprocket is fixedly connected to a locking block, and the drive shaft is provided with a locking groove that is slidably connected to the locking block.

[0008] Furthermore, several fixing rods are provided on both sides of the positioning frame, and the fixing rods are slidably connected to sliding seats that are slidably connected to the adjacent sowing legs.

[0009] Furthermore, the positioning frame is fixedly connected with several toothed plates, and the sliding seat is fixedly connected with toothed blocks that mesh with adjacent toothed plates.

[0010] Furthermore, both ends of the positioning frame are equipped with adjusting screws, and the adjusting screws are screwed to several engagement seats that are slidably connected to the positioning frame. The top and bottom of the positioning frame are equipped with fixed plates that are fixedly connected to the machine frame. The adjusting screws are rotatably connected to the fixed plates. The top and bottom ends of the engagement seats are rectangular, and the rectangular ends of the engagement seats are slidably connected to the inside of the positioning frame.

[0011] Furthermore, the adjusting screw is equipped with several screw guards, and the engagement seat and the fixing plate are fixedly connected to the ends of the adjacent screw guards.

[0012] Preferably, both ends of the positioning frame are screwed together with fixing screws, which pass through the side wall of the frame.

[0013] Preferably, the top of the sowing leg is provided with a positioning cylinder that is fixedly connected to the adjacent sliding seat, a rotating cylinder is rotatably connected inside the positioning cylinder, a rotating rod that is fixedly connected to the top of the sowing leg and rotated inside the rotating cylinder, and several limiting blocks that are fixedly connected to the top of the sowing leg and slidably connected to the interior of the adjacent sliding seat.

[0014] Furthermore, a rotating disk is fixedly connected to the top of the screw-in cylinder, and the rotating disk is equipped with locking screws that engage with the positioning cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The rectangular blocks are equipped with linkage modules. The fertilizer box and seed box are separated into several storage spaces by partitions. Seeds of one crop can be placed in several storage spaces on one side of the seed box, while seeds of another crop can be placed in the remaining storage spaces. The corresponding fertilizer is placed inside the fertilizer box. The linkage modules can be linked with the rectangular blocks to connect two adjacent connecting shafts. The linkage modules between the two types of crop seeds can be detached, allowing the connecting shafts at the bottom of the two types of crop seeds to be linked separately. This allows for the simultaneous sowing of two types of crop seeds. In this way, the intercropping sowing of two crops can be completed simultaneously in one pass, which helps to simplify the operation process, improve the operation efficiency, and facilitate efficient operation in the intercropping and relay cropping mode.

[0016] By engaging the toothed block with the toothed plate, the toothed plate can restrict the position of the fixed rod through the sliding seat, thereby restricting the position of the sliding seat. When selecting different intercropping methods, the toothed plate can be moved upward to disengage from the sliding seat. At this time, the sliding seat can be moved horizontally on the fixed rod to adjust the horizontal position of the sowing leg. Furthermore, the height of several sowing legs can be adjusted according to the planting depth, which is beneficial for adapting to different intercropping sowing methods.

[0019] 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.

[0020] Please see Figure 1-7 In this embodiment of the invention, a smart agricultural rotary tiller integrating planting and fertilization includes a rotary tiller module 100, a seeding module 200, and a frame 110. A rotary tiller frame 120 is rotatably connected inside the frame 110. A transmission box 130, which is drively connected to the rotary tiller frame 120, is located inside the frame 110. Connecting frames 140 are provided on both sides of the frame 110, and outer frames 150 are provided on the connecting frames 140. A leveling cylinder 160 is rotatably connected to the frame 110. The seeding module 200 includes a fertilizer box 210, a seed box 220, and a positioning frame 260. Both the fertilizer box 210 and the seed box 220 are fixedly connected inside the frame 110. The positioning frame 260 is slidably disposed inside the frame 110. Several limiting seats 111 are fixedly connected inside the frame 110 and slidably connected to the positioning frame 260. Several feeding boxes 230 are provided at the bottom of both the fertilizer box 210 and the seed box 220. The feeding boxes 230 are connected to the feeding pipe 231. Several partitions are fixedly connected inside both the fertilizer box 210 and the seed box 220. The partitions divide the inside of the fertilizer box 210 and the seed box 220 into several storage spaces. The feeding box 230 is rotatably connected to a separating block. The separating block has several separating slots. The distributing block is fixedly connected to the connecting shaft 232. Both ends of the connecting shaft 232 are fixedly connected to rectangular blocks 233. A linkage module 300 is set between two adjacent rectangular blocks 233. The linkage module 300 includes two linkage frames 310. The linkage frames 310 are slidably connected to the adjacent rectangular blocks 233. Several connecting bolts 320 are set between the two linkage frames 310. Several sowing legs 240 are set on the positioning frame 260. The feeding pipe 231 is connected to the adjacent sowing legs 240. The sowing legs 240 are located between the rotary tiller 120 and the leveling cylinder 160. The several sowing legs 240 are divided into two rows. One row of sowing legs 240 is connected to the feeding pipe 231 at the bottom of the fertilizer box 210, while the other row of sowing legs 240 is connected to the feeding pipe 231 at the bottom of the seed box 220. The two rows of sowing legs 240 are staggered and have different heights to avoid direct contact between fertilizer and seeds. The positioning frame 260 is located between the two rows of sowing legs 240.

[0021] Specifically, the fertilizer box 210 and the seed box 220 are separated into several storage spaces by a partition. One type of crop seed can be placed in several storage spaces on one side of the seed box 220, and another type of crop seed can be placed in the remaining storage spaces of the seed box 220. The corresponding fertilizer is placed inside the fertilizer box 210. The rotary tillage module 100 can be connected to the tractor, and the transmission box 130 can be connected to the output shaft of the tractor. The connecting bolt 320 can keep the two linkage frames 310 closed. In this way, the two adjacent connecting shafts 232 can be linked by the linkage frame 310 and the rectangular block 233. The connecting bolt 320 of the linkage module 300 between the two types of crop seeds can be removed, and the linkage frame 310 can be removed. In this way, the connecting shafts 232 at the bottom of the two types of crop seeds can be linked respectively. The rotary tiller module 100 can be pulled forward by a tractor. The tractor's output shaft can drive the rotary tiller frame 120 to rotate through the transmission box 130, thereby causing the rotary tiller frame 120 to rotate and break up the soil. This can cause the connecting shaft 232 to rotate. Several connecting shafts 232 at the bottom of the same crop seed can be linked together through the linkage module 300. The connecting shaft 232 can drive the distribution block to rotate. After the fertilizer in the fertilizer box 210 and the seeds in the seed box 220 fall into the corresponding feeding box 230, they will fall into the distribution groove. By rotating the distribution block, the seeds or fertilizer will fall into the feeding pipe 231, and then into the sowing leg 240. They will then fall into the soil from the bottom of the sowing leg 240. Then, the soil will be leveled by the leveling cylinder 160. This method can accommodate the sowing of two crops. In this way, the intercropping sowing of two crops can be completed simultaneously in one pass, which is conducive to simplifying the operation process, improving the operation efficiency, and facilitating efficient operation in the intercropping and relay cropping mode. A GPS locator can be installed on the tractor to pinpoint its location. Based on the work area, a work path can be planned, and the tractor can be navigated via a navigation module. The theoretical seed quantity can be calculated based on the tractor's work path and sowing parameters. After a work trip, the theoretical and actual remaining seed quantity in the seed box 220 is compared to the actual remaining quantity, facilitating timely understanding of the sowing situation. The sowing situation and tractor work path are then uploaded to the system via the Internet, realizing IoT monitoring of sowing. Example 1

[0022] like Figure 7-9 As shown, in this embodiment, a plurality of fixing rods 270 are provided on both sides of the positioning frame 260, and the fixing rods 270 are slidably connected to a sliding seat 271 that is slidably connected to the adjacent sowing leg 240.

[0023] In practice, the sliding seat 271 can move horizontally along the fixed rod 270, and the fixed rod 270 can support the sliding seat 271, thereby limiting the sowing leg 240.

[0024] like Figure 1-3 As shown, in this embodiment, the outer frame 150 is detachably fixed to the connecting frame 140 by screws. Two drive shafts 151 are rotatably connected inside the outer frame 150. Each drive shaft 151 is equipped with a sprocket 152, and the two sprockets 152 are connected by a chain drive. Two rotating shafts 141 are rotatably connected inside the connecting frame 140. Each rotating shaft 141 is fixedly connected to an adjacent connecting shaft 232. A drive wheel is mounted on each rotating shaft 141, and the two drive wheels are connected by a drive belt. One drive shaft 151 is fixedly connected to the end of one rotating shaft 141. Another drive shaft 151 is connected to the transmission box 130. The drive shaft 151 is slidably connected to a limit ring 153. The limit ring 153 can press the sprocket 152 against the annular protrusion on the side wall of the drive shaft 151. The limit ring 153 is provided with a positioning screw 155 that is screwed into the drive shaft 151. The positioning screw 155 can limit the position of the limit ring 153, thereby positioning the sprocket 152 through the limit ring 153. The sprocket 152 is fixedly connected to a locking block 154. The drive shaft 151 has a locking groove 156 that is slidably connected to the locking block 154.

[0025] In specific implementation, the output end of the transmission box 130 can drive another transmission shaft 151 to rotate. The transmission shaft 151 can drive the sprocket 152 to rotate through the slot 156 and the slot block 154. The other transmission shaft 151 can drive one transmission shaft 151 to rotate through two sprockets 152 and a chain. One transmission shaft 151 can drive one rotating shaft 141 to rotate. One rotating shaft 141 can drive another rotating shaft 141 to rotate through a transmission wheel and a transmission belt. The rotating shaft 141 can drive the adjacent connecting shaft 232 to rotate. Connecting frames 140 and outer frames 150 are provided on both sides of the frame 110, thereby driving the connecting shafts 232 on both sides of the bottom of the fertilizer box 210 or seed box 220 to rotate respectively, so as to realize the separate feeding and sowing of two kinds of seeds and the separate feeding of two kinds of fertilizers corresponding to the two kinds of seeds. The sprockets 152 in the two outer frames 150 are of different sizes, so that the rotation speed of several connecting shafts 232 on one side is different from that of the other connecting shafts 232, which is convenient to adapt to the sowing of different seeds. The screws on the outer frame 150 can be unscrewed, and the outer frame 150 can be removed from the connecting frame 140. Then the positioning screw 155 can be removed. At this time, the sprocket 152 and the limiting ring 153 can be removed from the drive shaft 151. By replacing the sprocket 152 with different sizes, the transmission ratio can be changed, thereby adapting to the sowing of different crop seeds. Example 2

[0026] Based on Example 1, such as Figure 7-11 As shown, in this embodiment, the positioning frame 260 is fixedly connected with a plurality of toothed plates 261, and the sliding seat 271 is fixedly connected with a toothed block 272 that meshes with the adjacent toothed plates 261. Adjusting screws 265 are provided at both ends of the positioning frame 260, and the adjusting screws 265 are screwed onto a plurality of engagement seats 263 that are slidably connected to the positioning frame 260. Fixed plates 250, which are fixedly connected to the frame 110, are provided at the top and bottom of the positioning frame 260. The adjusting screws 265 are rotatably connected to the fixed plates 250. 50 can support the adjusting screw 265. The top and bottom of the engagement seat 263 are both rectangular. The rectangular end of the engagement seat 263 is slidably connected to the inside of the positioning frame 260. The adjusting screw 265 is provided with several screw guards 264. The engagement seat 263 and the fixing plate 250 are fixedly connected to the ends of the adjacent screw guards 264. The adjusting screw 265 can be protected by the screw guards 264. The positioning frame 260 is screwed to both ends with fixing screws 262. The fixing screws 262 pass through the side wall of the frame 110.

[0027] In practice, adjusting the screw 265 can limit the position of the engagement seat 263, so that the rectangular top of the engagement seat 263 abuts against the positioning frame 260, limiting the height of the positioning frame 260. The height of the positioning frame 260 can also be limited by fixing screw 262. This allows the toothed plate 261 to remain against the toothed block 272. The toothed plate 261 and the toothed block 272 limit the horizontal position of the sliding seat 271, thereby limiting the horizontal position of the seeding leg 240. Before sowing, the fixing screw 262 can be unscrewed, and then the two adjusting screws 265 can be rotated in sequence. Since the side wall of the positioning frame 260 restricts the rotation of the rotating seat 263, the rotating seat 263 can be moved upward along the adjusting screw 265, so that the top of the rectangular rotating seat 263 no longer abuts against the positioning frame 260. Then, the two adjusting screws 265 can be rotated in sequence to move the rotating seat 263 upward. The bottom of the rectangular rotating seat 263 drives the positioning frame 260 to move upward, so that the toothed plate 261 disengages from the toothed block 272. At this time, the sliding seat 271 can be moved along the fixing rod 270 according to the planting needs, and the horizontal position of several sowing legs 240 can be adjusted to change the sowing row spacing. After adjustment, the two adjusting screws 265 can be rotated in reverse order to move the engagement seat 263 downward, thereby moving the positioning frame 260 downward. Finally, the rectangular top of the engagement seat 263 presses against the positioning frame 260, causing the toothed plate 261 to engage with the toothed block 272, thus limiting the position of the fixing rod 270 and maintaining the horizontal position of the sowing leg 240. The fixing screw 262 can also be screwed through the side wall of the frame 110 onto the positioning frame 260 to further limit the height of the positioning frame 260, which helps to improve the stability of fixing the sowing leg 240.

[0028] like Figure 8 and Figure 9 As shown, in this embodiment, the top of the sowing leg 240 is provided with a positioning cylinder 280 that is fixedly connected to the adjacent sliding seat 271. The positioning cylinder 280 is rotatably connected to a screw-in cylinder 281. The top of the sowing leg 240 is fixedly connected to a screw-in rod 241 that is screwed into the inside of the screw-in cylinder 281. The top of the sowing leg 240 is fixedly connected to a plurality of limiting blocks 242 that are slidably connected to the inside of the adjacent sliding seat 271. The top of the screw-in cylinder 281 is fixedly connected to a rotating disk 282. The rotating disk 282 is provided with a locking screw 283 that is screwed into the positioning cylinder 280. The positioning cylinder 280 can restrict the rotation of the rotating disk 282 through the locking screw 283, thereby restricting the rotation of the screw-in cylinder 281. The screw-in cylinder 281 can restrict the height of the sowing leg 240 through the screw-in rod 241.

[0029] In practice, the locking screw 283 can be unscrewed, and then the rotating cylinder 281 can be rotated by the rotating disk 282. The sliding seat 271 can restrict the rotation of the sowing leg 240 by the limiting block 242. When the rotating cylinder 281 rotates, the rotating rod 241 can move up or down. The rotating rod 241 can drive the sowing leg 240 to move, thereby adjusting the height of the sowing leg 240 according to the sowing needs and changing the application depth of seeds or fertilizers. After the adjustment is completed, the rotating disk 282 can be aligned with the positioning cylinder 280, so that the locking screw 283 passes through the rotating disk 282 and is screwed onto the outer edge of the top of the positioning cylinder 280 to fix the angle of the rotating cylinder 281.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
