Although the seed drill thus arranged has a certain efficiency, there will be a certain loss of the number of seeds. Therefore, a seed drill that can reduce seed loss and avoid seeds being discharged in piles on the soil surface is needed to solve the above problems. Summary of the invention

[0004] The technical solution adopted by the present invention to solve its technical problem is: A sowing and irrigation integrated machine for agricultural water conservancy projects, comprising a frame, a seed storage bin, and a sowing device, wherein the seed storage bin and the sowing device are both mounted on the frame and placed in the middle of the frame, and the seed storage bin is connected to the upper end of the sowing device; The sowing device comprises a sowing bin and a connecting pipe, wherein the connecting pipe is connected to the upper end of the sowing bin, and the sowing bin is driven to rotate by a motor and deposits seeds downward in batches; The sowing bin is provided with openings at both ends, the upper and lower openings are connected by a channel, and the sowing bin is provided with a dispersion part for dispersing the seeds dropped from the connecting pipe, and the dispersion part is sequentially connected with the two openings and the channel when the sowing bin rotates.

[0005] A preferred technical solution: the opening at the upper end of the sowing bin is connected to the connecting pipe through a connecting piece, and the connecting piece has an oblique hole arranged to be inclined downward.

[0006] A preferred technical solution: the sowing bin includes an outer shell and a rotating distributor, the outer shell is sleeved outside the rotating distributor, and the inner side surface of the outer shell abuts against the outer side surface of the rotating distributor, and the dispersion portion includes a flared groove arranged on the surface of the rotating distributor, and the flared groove has an arc-shaped surface.

[0007] A preferred technical solution: the flared groove is flared and gradually deepens, and the small-diameter end is arranged close to the lower end of the oblique hole, and the left and right ends of the flared groove extend to the two side edges of the rotating distribution member; The opening at the lower side of the outer shell is arranged close to the side with a larger diameter of the expansion groove.

[0008] A preferred technical solution: the surface of the expanding groove has a raised portion, the raised portion is an arc-shaped surface, the cross-section of the raised portion is expanding, and the raised portion extends from the middle of the expanding groove to the edge of the expanding groove.

[0009] A preferred technical solution: the channel includes a diverter groove arranged in the outer shell, the diverter groove is an inverted Y-shaped structure, when the rotating dividing member rotates, the expanded groove is connected to the upper end of the diverter groove, and the lower end of the diverter groove is connected to the opening on the lower side of the outer shell; The lower ends of the diverter grooves are respectively connected to the left and right sides of the lower opening of the outer shell.

[0010] A preferred technical solution: a baffle, a sliding extrusion block, and a boosting block are provided in the water tank to be connected to a nozzle for spraying water at the lower end of the boosting block, the baffle is symmetrically arranged on both sides above the boosting block, and a slideway for the sliding extrusion block to slide is provided between the baffle and the boosting block, and the sliding extrusion block is placed in the slideway; The output shaft of the motor is connected to the rotating distribution part through a crank, and the middle part of the crank is movably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to the sliding extrusion block through a rotating shaft. A slide groove is provided on the outside of the water tank near the sliding extrusion block, and the rotating shaft is placed in the slide groove, and the upper and lower heights of the slide groove are smaller than the thickness of the sliding extrusion block, so that the sliding extrusion block can slide left and right by driving the connecting rod through the crank while the motor rotates.

[0011] A better technical solution: the adjacent surfaces of the two baffles are inclined surfaces, and flow channels for liquid flow are respectively provided on the left and right sides of the sliding extrusion block. The upper end of the sliding extrusion block is respectively provided with a water guide groove on the left and right sides, and each water guide groove is connected with the adjacent flow channel through a connecting hole, and the flow channel passes through the boosting block and is connected with the nozzle.

[0012] A preferred technical solution: A boost drain is provided on both side edges of the upper end of the boost block, and a boost chamber connected to the nozzle is provided in the inner middle of the boost block, and the boost drain extends into the boost chamber in an inclined shape.

[0013] Compared with the background technology, this technical solution has the following advantages: The sowing bin in the present invention is provided with openings at both upper and lower ends, and the upper and lower openings are connected by a channel, and the sowing bin is provided with a dispersion part for dispersing the seeds dropped from the connecting pipe, and the dispersion part is sequentially connected with the two openings and the channel when the sowing bin rotates. The two openings can be regarded as receiving and discharging the seeds respectively, and since the dispersion part arranged on the circumference of the sowing bin can be continuously connected with the upper end of the channel when the sowing bin rotates, based on such a working principle, the seeds falling along the connecting pipe can fall through the channel connected with the dispersion part after being discharged into the dispersion part, and finally be discharged outwardly into the land along the opening on the lower side of the sowing bin, and after the seeds are discharged into the soil, the operator can cooperate with the all-in-one machine in the present invention to water the seeds to achieve the environmental conditions required for seed planting, so that the all-in-one machine in the present invention has the advantages of efficient seed distribution, simplified planting process, optimized planting conditions, and improved resource utilization.

[0014] In the present invention, since the cross-section of the oblique hole is flared, the end with a smaller diameter is connected to the upper opening of the rotating distributor, so the seed transmission amount can be controlled, which helps to avoid too many seeds being put in one time, reduce seed waste and the problem of over-dense planting, that is, the seed passing amount is reduced by gradually reducing the inner diameter of the oblique hole. Through the oblique hole set at an angle downward, the seeds will pass through a longer path during the sliding process, thereby achieving a more uniform seed distribution, which helps to avoid the aggregation or sparseness of seeds in the sowing area, improve the growth uniformity and yield of crops, and by extending the seed sliding path and sliding time, the seeds can be more evenly distributed in the sowing area, which helps to improve the sowing accuracy and reduce the spacing differences between seeds, thereby improving the growth consistency and yield stability of crops.

[0015] In the present invention, if there are still some seeds in the expanded groove that cannot be discharged to the opening on the lower side of the sowing bin through the channel when the rotating divider rotates, they will move in the sowing bin with the rotation of the rotating divider, and finally be discharged through the opening on the lower side of the sowing bin. This arrangement is to prevent blockage. If there are too many undischarged seeds in the expanded groove, it is likely that the operator needs to discharge a large number of seeds for planting. In this way, the seeds that fall into the expanded groove will also be evenly discharged into the soil in piles and batches as the rotating divider rolls periodically. This can also avoid the technical problems of the seed drill in the prior art. It can be understood that the present invention can effectively adapt to the user's requirements for different seeding amounts.

[0016] In addition, the present invention can use the inverted Y-shaped structure of the diversion groove to allow the seeds to smoothly pass through the expanded groove to achieve diversion when the rotating divider rotates, thereby reducing blockage and jamming. The invention can effectively avoid the seeds from being too densely packed, which is beneficial to the growth and development of the seeds.

[0017] When the sliding extrusion block slides back and forth, it will squeeze the water flow in the flow channels on both sides and discharge the water through the nozzle at the lower end of the boosting block. When the air pressure inside and outside the boosting block is stable and the nozzle is not a one-way pressure relief nozzle, the water flowing into the flow channel through the water guide groove can be sprayed out through the nozzle without sliding and squeezing the sliding extrusion block. The nozzle in the present invention is a boosting nozzle, which can be opened only after the water pressure in the boosting block reaches a threshold value, and as shown in the figure, a boosting discharge channel is respectively provided on both sides of the upper end of the boosting block, and the boosting block The middle part of the inner side is provided with a boosting chamber connected with the nozzle, and the boosting discharge channel extends into the boosting chamber in an inclined shape. Based on this, the water flow on the sliding extrusion block will first flow into the flow channel through the water guide groove, and then enter the boosting chamber through the flow channel for accumulation. When the boosting chamber is filled with water, the sliding extrusion block can squeeze the water in the flow channel, and the connecting hole on this side is closed by the baffle. Therefore, the water in the flow channel on this side will not flow back, thereby increasing the internal pressure of the boosting block. After reaching the nozzle pressure threshold, the water will be sprayed out in an expanded shape to expand the water spraying coverage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] like Figure 1-9 As shown, a sowing and irrigation integrated machine for agricultural water conservancy projects includes a frame 1, a seed storage bin 2, and a sowing device 3. The seed storage bin 2 and the sowing device 3 are both installed on the frame 1 and placed in the middle of the frame 1. The seed storage bin 2 is connected to the upper end of the sowing device 3. The sowing device 3 includes a sowing bin 32 and a connecting pipe 34. The connecting pipe 34 is connected to the upper end of the sowing bin 32. The sowing bin 32 is driven to rotate by a motor 33 and the seeds are discharged downward in batches. It can be understood that the present invention stores the seeds to be discharged through the seed storage bin 2 when in use. The integrated machine in the present invention discharges the seeds into the sowing bin 32 during movement, and the sowing bin 32 is driven by the motor 33 to evenly sprinkle the seeds discharged into the sowing bin 32 on the moving path of the integrated machine. The technical problems described in the background technology are solved by such design and working method. The technical scheme in the present invention will be further introduced as follows: The sowing bin 32 of the present invention is provided with openings at both the upper and lower ends, and the upper and lower openings are connected by a channel, and the sowing bin 32 is provided with a dispersing part for dispersing the seeds dropped from the connecting pipe 34, and the dispersing part is sequentially connected with the two openings and the channel when the sowing bin 32 rotates, and the two openings can be regarded as receiving and discharging the seeds respectively, and because the dispersing part arranged on the peripheral surface of the sowing bin 32 can be continuously connected with the upper end of the channel when the sowing bin 32 rotates, based on such a working principle, the seeds falling along the connecting pipe 34 can fall through the channel connected with the dispersing part after being discharged into the dispersing part, and finally be discharged outwardly into the land along the opening on the lower side of the sowing bin 32, and after the seeds are discharged into the soil, the operator can cooperate with the all-in-one machine of the present invention to perform the seed watering work to achieve the environmental conditions required for seed planting; Based on the above content, the present invention has the following advantages compared with the prior art: Efficient seed dispersion: Through the designed dispersion part, the present invention can effectively receive the seeds from the upper opening and disperse them to the lower opening through the channel when rotating. This design ensures that the seeds can be evenly and effectively dispersed to the predetermined planting area, thereby improving the planting efficiency; Simplify the planting process: Through the integrated design, operators can easily water the seeds without the need for additional equipment and operating steps, thus reducing the workload of operators; Optimize planting conditions: The present invention uses a coordinated integrated machine to water the seeds, which can ensure that the seeds obtain appropriate environmental conditions after being discharged into the soil, thereby facilitating the growth and development of the seeds. This provides the best growth environment for the seeds and further improves the success rate of planting; Improve resource utilization: Since seeds can be evenly and effectively distributed to the planting area, the present invention reduces seed waste and improves seed utilization; Flexibility: The present invention can be applied to different types of seeds and planting environments, showing good adaptability. This flexibility enables the present invention to be widely used in different agricultural production scenarios.

[0030] Furthermore, the opening at the upper end of the sowing bin 32 is connected to the connecting pipe 34 through a connecting piece 323, and the connecting piece 323 has an oblique hole 3231 arranged to be inclined downward, mainly through the oblique hole 3231 to discharge seeds into the sowing bin 32, and the role of the oblique hole 3231 is to extend the seed sliding path and sliding time. At the same time, as shown in the figure, since the cross-section of the oblique hole 3231 is flared, the end with a smaller diameter is connected to the upper opening of the rotating distribution member 322, the seed transmission amount can be controlled, which helps to avoid too much seeds being put in at one time and reduce the seed loss. The problem of waste and over-dense planting is solved by gradually reducing the inner diameter of the oblique hole 3231 to reduce the seed passing through. Through the oblique hole 3231 set at an angle downward, the seeds will pass through a longer path during the sliding process, thereby achieving a more uniform seed distribution, which helps to avoid the aggregation or sparseness of seeds in the sowing area, improves the growth uniformity and yield of crops, and by extending the seed sliding path and sliding time, the seeds can be more evenly distributed in the sowing area, which helps to improve the sowing accuracy and reduce the spacing differences between seeds, thereby improving the growth consistency and yield stability of crops.

[0031] The outer shell 321 is sleeved on the outer surface of the rotating distribution member 322, and the inner side surface of the outer shell 321 abuts against the outer side surface of the rotating distribution member 322. The dispersion portion includes a flaring groove 3221 arranged on the surface of the rotating distribution member 322, and the flaring groove 3221 has an arc-shaped surface. The flaring groove 3221 is flared and gradually deepens, and the small-diameter end is arranged close to the lower end of the oblique hole 3231, and the left and right ends of the flaring groove 3221 extend to the two side edges of the rotating distribution member 322, and the opening located on the lower side of the outer shell 321 is arranged close to the large-diameter side of the flaring groove 3221. The sowing bin 32 arranged in this way can ensure good abutment between the outer shell 321 and the rotating distribution member 322, avoid gaps and cause seed leakage, and can pass the flaring groove 3221 to The seeds are guided to both sides, and the moving path of the seeds is extended again. If, when the rotating dividing member 322 rotates, there are still some seeds in the expanded groove 3221 that cannot pass through the channel to the opening on the lower side of the sowing bin 32, they will move in the sowing bin 32 with the rotation of the rotating dividing member 322, and finally be discharged along the opening on the lower side of the sowing bin 32. This arrangement is to prevent blockage. If there are too many undischarged seeds in the expanded groove 3221, it is likely that the operator needs to discharge a large number of seeds for planting. Then, the seeds that fall into the expanded groove 3221 will also be evenly discharged into the soil in piles and batches as the rotating dividing member 322 periodically rolls, which can also avoid the technical problems of the seeding machine in the prior art. It can be understood that the present invention can effectively adapt to the user's requirements for different seeding amounts. Among them, the surface of the expanded groove 3221 has a raised portion 3222, which is an arc-shaped surface. The cross-section of the raised portion 3222 is expanded, and the raised portion 3222 extends from the middle of the expanded groove 3221 to the edge of the expanded groove 3221. The raised portion 3222 also exists to divert seeds, mainly through the protruding structure of the raised portion 3222 to divide the seeds passing through the expanded groove 3221 into left and right sides for movement.

[0032] Furthermore, in order to allow the seeds to be discharged from the left and right parts of the lower opening of the sowing bin 32 respectively, and to expand the sowing range of the seeds and the spacing between the seeds, the channel includes a diverter groove 3211 arranged in the outer shell 321, and the diverter groove 3211 is an inverted Y-shaped structure. When the rotating dividing member 322 rotates, the expanded groove 3221 is connected to the upper end of the diverter groove 3211, and the lower end of the diverter groove 3211 is connected to the opening on the lower side of the outer shell 321, and the lower end of the diverter groove 3211 is connected to the left and right sides of the lower opening of the outer shell 321 respectively. Therefore, through the inverted Y-shaped structure of the diverter groove 3211, when the rotating dividing member 322 rotates, the seeds can be smoothly diverted through the expanded groove 3221, reducing blockage and jamming. The invention can effectively avoid the seeds from being too dense, which is beneficial to the growth and development of the seeds.

[0033] Furthermore, in order to realize that the seeds can be watered while being sown, to provide moisture to the seeds and to flush the seeds into the soil, thus realizing an integrated planting process, the present invention makes the following improvements: The water tank 31 of the present invention is provided with a baffle 311, a sliding extrusion block 312, and a booster block 313 to communicate with a nozzle for spraying water at the lower end of the booster block 313. The baffle 311 is symmetrically arranged on both sides above the booster block 313, and a slideway for sliding the sliding extrusion block 312 is arranged between the baffle 311 and the booster block 313. The sliding extrusion block 312 is placed in the slideway. The output shaft of the motor 33 is connected to the rotating distribution member 322 through a crank 331, and the middle part of the crank 331 is movably connected to a connecting rod 332, and the other end of the connecting rod 332 is rotatably connected to the sliding extrusion block 312 through a rotating shaft. The outer side of the water tank 31 is close to the outer surface of the water tank 31. A slide groove is provided near the sliding extrusion block 312, and the rotating shaft is placed in the slide groove, and the upper and lower heights of the slide groove are less than the thickness of the sliding extrusion block 312, so that the sliding extrusion block 312 can be driven to slide left and right by the connecting rod 332 driven by the crank 331 while the motor 33 rotates. The adjacent surfaces of the two baffles 311 are inclined surfaces, and the left and right sides of the sliding extrusion block 312 are respectively provided with flow channels for liquid flow. The left and right sides of the upper end of the sliding extrusion block 312 are respectively provided with a water guide groove 3121, and each water guide groove 3121 is connected to the adjacent flow channel through a connecting hole 3122, and the flow channel passes through the booster block 313 and is connected to the nozzle; The above is the relevant equipment structure of the present invention for solving the irrigation technology. The working principle and effect of the above equipment structure will be further introduced below: The water tank 31 is filled with water. When the motor 33 drives the sowing bin 32 to rotate and discharge the seeds evenly, the connecting rod 332 can be driven by the crank 331 to slide the sliding extrusion block 312 left and right. Since the surface of the sliding extrusion block 312 is provided with a water guide groove 3121 and a connecting hole 3122, when the crank 331 rotates one circle, the sliding extrusion block 312 will slide back and forth once. When the sliding extrusion block 312 slides to the connecting hole 3122 is exposed, water will be poured into the flow channel on the corresponding side of the sliding extrusion block 312 through the connecting hole 3122. When the sliding extrusion block 312 slides back and forth, it will squeeze the water flow in the flow channels on both sides and discharge the water through the nozzle at the lower end of the boosting block 313. When the air pressure inside and outside the boosting block 313 is stable and the nozzle is not a one-way pressure relief nozzle, the water flowing into the flow channel through the water guide groove 3121 can pass through the nozzle without sliding and squeezing the sliding extrusion block 312. The nozzle in the present invention is a boost nozzle, which can be opened only after the water pressure in the boost block 313 reaches a threshold value, and as shown in the figure, the upper edge of the boost block 313 is provided with a boost channel 3132 on both sides, and the inner middle part of the boost block 313 is provided with a boost chamber 3131 connected to the nozzle, and the boost channel 3132 extends obliquely into the boost chamber 3131. Based on this, the water flow on the sliding extrusion block 312 It will first flow into the flow channel through the water guide groove 3121, and then enter the boost chamber 3131 through the flow channel for storage. When the boost chamber 3131 is filled with water, the sliding extrusion block 312 can squeeze the water in the flow channel, and the connecting hole 3122 on this side is closed by the baffle 311. Therefore, the water in the flow channel on this side will not flow back, thereby increasing the internal pressure of the boost block 313. After reaching the nozzle pressure threshold, the water will be sprayed out in an expanded shape to expand the water spray coverage.

[0034] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
