Description

Technical Field

[0001] The present application relates to the technical field related to agricultural machinery and equipment, and in particular to an intelligent agricultural machinery and equipment integrating sowing, fertilization and irrigation. Background Art

[0002] Sowing, fertilizing and irrigation are necessary stages in the growth and development of agricultural seedlings. In order to save labor and improve agricultural production efficiency, intelligent agricultural machinery equipment covering integrated sowing, fertilization and irrigation has gradually appeared on the market. The emergence of this equipment has effectively liberated a large number of labor forces and improved agricultural production efficiency.

[0003] Among them, the fertilization stage is a very important part of the seedling growth process. Appropriate fertilizers and dosage can effectively accelerate the growth of seedlings. On the contrary, excessive fertilizers will cause root rot due to excessive fertilizer. In order to improve the utilization rate of fertilizers and accelerate the absorption of fertilizers by seedlings, general technicians will mix fertilizers with water according to the required ratio to form liquid fertilizers and directly transport them into the soil. On the one hand, it accelerates the absorption of seedling roots, and on the other hand, it can also achieve the effect of irrigation, thereby accelerating the growth and development of seedlings. Affected by local weather and factors such as soil structure, shape and inclination, the soil density and soil moisture of different seedling planting sites in the same area will be different. Therefore, if the amount of liquid fertilizer transported into the soil is the same, it will inevitably cause the roots of seedlings with high soil density and low humidity to absorb fertilizers. The effect is reduced. On the contrary, the roots of seedlings with low soil density and high humidity will absorb too much liquid fertilizer, causing root rot.

[0004] When existing integrated intelligent agricultural machinery for sowing, fertilizing and irrigation delivers liquid fertilizers to the soil, it is difficult to determine the dryness of the soil layers at different seedling planting locations in real time, and to automatically control the amount of fertilizer delivered to the soil according to the soil dryness. Summary of the invention

[0005] The present application proposes an intelligent agricultural machinery equipment for sowing, fertilizing and irrigation, which has the function of triggering the opening of water retaining blocks at different heights on the diversion block according to the change in the size of the resistance when the impact drill bit is inserted into the soil layer at the root of the seedling, combined with the adaptive compression deformation action of the first spring, so as to achieve the advantage of automatically changing the amount of liquid fertilizer delivered to the soil under the limit of the rated insertion distance and the rated time, so as to avoid the problem of poor development and root rot caused by too much or too little fertilizer due to different absorption effects of fertilizer by the roots of different seedlings due to different soil dryness conditions at the roots of the seedlings, and the problem of difficulty in judging the dryness of the soil layers at different seedling planting locations in real time when the existing intelligent agricultural machinery equipment for sowing, fertilizing and irrigation delivers liquid fertilizer to the soil, and automatically controlling the amount of fertilizer delivered to the soil according to the soil dryness conditions.

[0007] Furthermore, a limiting ring for limiting the ultimate compression distance of the first spring is fixedly connected to the inner wall of the impact tube, a limiting sleeve is connected through the bottom of the equipment box, the infusion tube is inserted and slid in the limiting sleeve, and the bottom end extends outside the limiting sleeve.

[0008] Furthermore, a diverter block is fixedly connected to the strip drainage groove located on the impact tube, a plurality of array-distributed grooves are provided in the diverter block, and corresponding drainage holes are provided in the grooves, a water retaining block is fitted and connected to the inner wall of the drainage hole, a first limiting groove is provided in the groove, and the water retaining block is limitedly and slidably connected in the first limiting groove, a fixed block is fixedly connected to one end of the first limiting groove close to the infusion tube, a second spring is fixedly connected between the fixed block and the water retaining block, a sealing plug is embedded at the bottom end of the infusion tube, a magnetic rod is fixedly connected to the sealing plug, and the water retaining block is made of magnetic material, and the magnetism is opposite to that of the magnetic rod.

[0009] Furthermore, an anti-collision block is fixedly connected to one side of the fixed block opposite to the water retaining block, and the anti-collision block is inserted into the second spring.

[0010] Furthermore, a sealing gasket is fixedly connected to one side of the diverter block located in the impact tube, and the inner wall contour of the sealing gasket is matched with the inner wall contour of the impact tube.

[0011] Furthermore, the impact drill bit is conical in shape, and the outer circle contour of the larger end is larger than the outer circle contour of the bottom end of the impact tube.

[0012] Furthermore, a side of the water retaining block relative to the second spring is arranged as an inclined surface, and the highest point of the inclination is the side close to the first limiting groove.

[0013] Furthermore, the surfaces of the infusion tube, the impact tube, the impact drill bit and the first spring are all sprayed with an anti-rust coating.

When the compression deformation of the first spring is large, under the rated limit of the distance injected into the soil by the impact drill bit, the strip drainage groove on the infusion tube and the strip drainage groove on the impact tube are aligned with each other. The larger the overlapping area of ​​the two strip drainage grooves is, the more liquid fertilizer in the infusion tube will flow out through the strip drainage grooves on the impact tube. Conversely, the smaller the compression deformation of the first spring is, the smaller the overlapping area of ​​the two strip drainage grooves is under the rated injection distance limit, and the less liquid fertilizer will flow out of the strip drainage grooves. This realizes automatic judgment of the dryness of the soil and the fertilizer requirement according to the size of the soil resistance exerted on the first spring, and automatically changes the amount of liquid fertilizer injected, so as to achieve the effect of automatically injecting an appropriate amount of liquid fertilizer according to the specific soil conditions at the root of the seedling. This not only better adapts to the fertilizer demand of the seedling root, but also greatly reduces the occurrence of poor development of the seedling due to insufficient fertilizer or root rot caused by excessive fertilizer. It also saves the use of liquid fertilizer to a certain extent, better saves resources, reduces the cost of fertilization and irrigation, and realizes real-time judgment of the dryness of the soil layers at different seedling planting locations, and automatically controls the amount of fertilizer delivered to the soil according to the soil dryness.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0020] like Figure 1-Figure 9As shown, before the device directly delivers the liquid fertilizer into the soil, the liquid fertilizer will enter the liquid infusion tube 5 through the guide tube 4. At this time, the top of the liquid infusion tube 5 is fixedly connected to the connecting plate 3, and a sealing plug 510 is installed at the water outlet at the bottom of the liquid infusion tube 5. The pipe body part of the strip-shaped drainage groove 504 on the liquid infusion tube 5 is piston-connected to the impact tube 502, thereby achieving a sealing effect of the liquid infusion tube 5, so that the liquid fertilizer can be sealed and stored in the liquid infusion tube 5. Then, when the electric telescopic shaft of the electric push rod 2 drives the connecting plate 3 to move downward, the connecting plate 3 will push The two infusion tubes 5 fixedly connected thereto move vertically downward under the limit of the limit sleeve 501. Since a pressure sensor 508 is fixedly installed at the bottom end of the infusion tube 5, and a first spring 507 is fixedly connected between the pressure sensor 508 and the impact drill bit 503 fixedly connected to the bottom end of the impact tube 502, under the setting of the first spring 507, when the infusion tube 5 moves downward, the infusion tube 5 will push the pressure sensor 508 and the first spring 507 to move downward, and drive the impact drill bit 503 to move downward synchronously. When the bottom end 3 contacts the soil surface, it will be subject to the resistance of the soil itself, thereby causing the first spring 507 to be compressed and deformed during the mutual extrusion process. The degree of compression deformation is closely related to the soil density and soil moisture. Under the rated downward movement distance, the greater the soil density and the smaller the soil moisture, the greater the compression deformation of the first spring 507 when the impact drill bit 503 reaches the specified point. On the contrary, the smaller the soil density and the greater the soil moisture, the smaller the compression deformation of the first spring 507 when the impact drill bit 503 reaches the specified point. When the first spring 507 is compressed, the first spring 507 is compressed and deformed. When the deformation amount is large, under the rated limit of the distance of the impact drill bit 503 injected into the soil, the overlapping area of ​​the strip drainage groove 504 opened on the infusion tube 5 and the strip drainage groove 504 opened on the impact tube 502 is larger, which means that more liquid fertilizer in the infusion tube 5 flows out through the strip drainage groove 504 on the impact tube 502. Conversely, the smaller the compression deformation amount of the first spring 507 is, under the rated injection distance limit, the smaller the overlapping area of ​​the two strip drainage grooves 504 is, and the less liquid fertilizer flows out of the strip drainage groove 504.

[0021] The specific manifestation corresponding to the above changes is that when the soil density is greater and the soil moisture is smaller, it means that the soil is dry and the soil is prone to soil compaction, which means that the water content of the land is too little and more liquid fertilizer needs to be injected. At this time, the corresponding first spring 507 has a large compression deformation, and more liquid fertilizer will flow out of the strip drainage groove 504, thereby better replenishing fertilizer and water for the roots of the seedlings. On the contrary, the smaller the soil density and the greater the soil moisture, it means that the soil is moist and the soil tends to be in a muddy state, which means that there is too much water in the land and only a small amount of liquid fertilizer needs to be injected into the root soil. At this time, the corresponding first spring 507 has a small compression deformation, and even less liquid fertilizer will flow out of the strip drainage groove 504, thereby avoiding the problem of root rot caused by excessive fertilizer and water at the roots of the seedlings. The above structure and theory As described above, the device can automatically judge the dryness of the soil and the amount of fertilizer required according to the performance of the soil density and soil moisture in the natural state and the rated distance of the impact drill bit 503 inserted into the soil according to the size of the soil resistance of the first spring 507, and automatically change the amount of liquid fertilizer injected, so as to automatically inject an appropriate amount of liquid fertilizer according to the specific soil conditions at the roots of the seedlings, which not only better meets the fertilizer needs of the roots of the seedlings, but also greatly reduces the occurrence of poor development of the seedlings due to insufficient fertilizer or root rot due to excessive fertilizer, and also saves the use of liquid fertilizer to a certain extent, better saves resources, and reduces the cost of fertilization and irrigation. At the same time, there is no need to judge the soil state with the naked eye, which also solves the problem of high labor intensity caused by the need for technicians to observe the soil conditions one by one for fertilization. Embodiment 2

[0022] On the basis of Example 1, further supplements are made, such as Figure 3-Figure 5 As shown, a pressure sensor 508 is fixedly installed at the bottom of the infusion tube 5 and is fixedly connected to the first spring 507. Under this setting, it can be determined whether the first spring 507 has metal fatigue problems due to repeated compression and resetting during long-term use. The judgment is based on the monitoring of the external controller, pressing the impact drill bit 503 upward to make the bottom of the pressure sensor 508 abut against the limit ring 509. According to the pressure applied to the pressure sensor 508 by the first spring 507 at the time of extreme compression in the normal state and the pressure applied to the pressure sensor 508 by the first spring 507 at the time of extreme compression in the actual state, if the extreme pressure value in the actual state is less than the extreme pressure value in the normal state, it can be concluded that the first spring 507 has metal fatigue. This is used for equipment self-test, thereby avoiding the problem of inaccurate judgment of the soil dryness by the equipment due to metal fatigue of the first spring 507 without knowing it, while reducing the failure rate of the equipment when it is working, and avoiding various unexpected cost wastes caused by equipment failures during working hours. Embodiment 3

[0023] On the basis of the first embodiment, further improvements are made, such as Figure 4-Figure 9As shown, a plurality of grooves are provided in the diverter block 505, and drainage holes for the outflow of liquid fertilizer are provided in the plurality of grooves, wherein the outline of the water retaining block 506 is larger than the inner diameter of the drainage hole, and is fitted to the inner side of the drainage hole. Through the magnetic rod 6 fixedly connected to the sealing plug 510, and the water retaining block 506 made of magnetic material, and the water retaining block 506 and the magnetic rod 6 have opposite magnetic properties, when the infusion tube 5 drives the sealing plug 510 and the magnetic rod 6 to move downward in the impact tube 502, the strip drainage groove 504 provided on the infusion tube 5 and the strip drainage groove 504 provided on the impact tube 502 will gradually overlap. In the process of the two strip drainage grooves 504 gradually overlapping, the magnetic rod 6 will pass through the opposite magnetic properties between the plurality of water retaining blocks 506, The water retaining blocks 506 at the corresponding positions are attracted one by one from top to bottom to approach it, thereby opening the drainage holes provided in the grooves, so that the liquid fertilizer can flow out smoothly. Since the water retaining block 506 is connected to the first limiting groove 601 provided in the corresponding groove on the diverter block 505 for limiting sliding, and one end of the second spring 603 is fixedly connected to the fixed block 602 fixedly connected to the first limiting groove 601 near one end of the magnetic rod 6, and the other end of the second spring 603 is fixedly connected to the water retaining block 506, in the process of the water retaining block 506 gradually approaching the magnetic rod 6, the water retaining block 506 will slide toward the magnetic rod 6 under the limitation of the first limiting groove 601, and the setting of the first limiting groove 601 can provide a more stable limiting effect for the movement of the water retaining block 506. The effect is to avoid the deflection and detachment of the corresponding groove under the impact of water flow, which causes the problem that the drainage hole cannot be opened and closed normally. The water retaining block 506 will squeeze the second spring 603 together with the fixed block 602 during the movement to cause compression deformation. Here, the magnetic attraction between the magnetic rod 6 and the water retaining block 506 is greater than the elastic force of the second spring 603. Therefore, under the action of the magnetic attraction of the magnetic rod 6, the water retaining block 506 will continue to be separated from the drainage hole opened in the groove, thereby ensuring that the liquid fertilizer can flow out continuously. In addition, each fixed block 602 is fixedly connected to a side of the water retaining block 506 relative to the water retaining block 506. The anti-collision block 604 is inserted in the second spring 603 to avoid the magnetic attraction between the magnetic rod 6 and the water retaining block 506. The problem of the second spring 603 being damaged due to the compression deformation being too large and causing the second spring 603 to be damaged further improves the safety of the equipment. The above process can achieve the effect that the drainage holes in the groove in the shunt block 505 are opened one by one according to the downward movement distance of the infusion tube 5, so as to avoid that when the two strip drainage grooves 504 fail to completely overlap, the liquid fertilizer will quickly flow out of the strip drainage groove 504 on the impact tube 502 and overflow into the impact tube 502, causing the first spring 507 to rust faster. When the liquid fertilizer flows out, it can be isolated and sealed by multiple water retaining blocks 506, so that only when the impact tube 502 moves to a specific corresponding position, the water retaining block 506 at the corresponding position will be attracted by the magnetic rod 6 to move and open.This can achieve a more precise discharge effect of the liquid fertilizer, and also prevent the external soil from entering the impact tube 502, which would cause blockage in the impact tube 502 and prevent the infusion tube 5 from moving down smoothly, thereby further improving the safety of the equipment.

[0024] In addition, the sealing gasket 605 can better seal the inner wall of the diverter block 505 and the outer wall of the infusion tube 5 to avoid the problem of liquid fertilizer overflow. Embodiment 4

[0025] On the basis of the first embodiment, further improvements are made, such as Figure 4-Figure 5 As shown, by sleeve-fixing the abutment ring 7 on the impact tube 502, and the abutment ring 7 is located above the diverter block 505, it can be achieved that after the impact tube 502 is inserted into the soil layer for a certain distance, the abutment ring 7 will provide a greater downward resistance when it fits with the soil surface due to its larger contour, thereby cooperating with the retraction action of the electric push rod 2 to further limit the descending distance of the impact tube 502, thereby ensuring that the distance of the impact tube 502 inserted into the soil is the same each time, which is convenient for the equipment to make a more accurate judgment on the dryness of the soil layer; wherein the outer surface of the impact tube 502 is provided with two symmetrically distributed second limiting grooves 701, and the second limiting groove 701 is located below the abutment ring 7, and the impact tube 502 is sleeved with a sliding ring 702 for sliding, and the sliding ring 702 is slidingly connected with the second limiting groove 701, which can achieve sliding. The movable ring 702 has the effect of freely moving up and down on the outer surface of the impact tube 502. Because the sliding ring 702 and the abutting ring 7 are both made of magnetic materials and have the same magnetic properties, when the sliding ring 702 is pushed to the top by the soil and contacts the surface of the abutting ring 7 during the descent of the impact tube 502, the magnetic repulsion force between the two is the largest, and when the impact tube 502 pulls out the soil, the sliding ring 702 is gradually pushed downward to the top of the impact drill bit 503 by the magnetic repulsion force. During this process, two cleaning brush blocks 703 for cleaning the soil on the surface of the diverter block 505 embedded in the inner ring of the sliding ring 702 will clean the soil on the surface of the diverter block 505 from top to bottom, complete the cleaning of the surface of the diverter block 505, and avoid the drainage holes on the diverter block 505 from being blocked by soil, thereby ensuring that the liquid fertilizer can flow out of the drainage holes smoothly.

[0026] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
