Description

Technical Field

[0001] The present invention relates to the field of tartary buckwheat planting equipment, and specifically to a mobile automatic fertilizing equipment for tartary buckwheat planting. Background Art

[0002] In agricultural production, tartary buckwheat, as a crop with high nutritional and economic value, has a gradually expanding planting area. The growth of tartary buckwheat has specific requirements for soil fertility and water conditions. Reasonable fertilization and irrigation are the key links to ensure high yield and good quality of tartary buckwheat.

[0003] For the traditional fertilization method in tartary buckwheat planting, manual spreading of fertilizers is mostly adopted. This method not only consumes a large amount of manpower, but also has uneven fertilizer distribution, easily resulting in too much or too little fertilizer in local areas. Excessive fertilizer may cause seedling burning, while too little fertilizer cannot meet the growth needs of tartary buckwheat, seriously affecting the yield and quality of tartary buckwheat. At the same time, manual spreading of fertilizers cannot accurately control the fertilization depth, with low fertilizer utilization rate. A large amount of fertilizers volatilize or are washed away by rainwater, causing both resource waste and potential environmental pollution.

[0004] With the development of agricultural mechanization, some fertilizing equipment has been gradually applied to agricultural production, but there are few special fertilizing equipment for tartary buckwheat planting. Some of the existing fertilizing equipment is difficult to adapt to complex terrains and different planting areas, and is not flexible and convenient enough during the moving process. Moreover, these equipment often only have a single fertilization function and cannot meet the water demand during the growth process of tartary buckwheat at the same time. If irrigation operations are to be carried out, additional watering equipment needs to be equipped separately, which undoubtedly increases the planting cost and the difficulty of equipment management.

[0005] In addition, during the fertilization process of the existing fertilizing equipment, it is easy to damage the roots of tartary buckwheat. For example, some equipment using the method of digging pits for fertilization will damage the capillary roots of tartary buckwheat, affecting the absorption of nutrients and water by tartary buckwheat, and thus affecting the normal growth and development of tartary buckwheat. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a mobile automatic fertilizing equipment for tartary buckwheat planting, which solves the problems of uneven fertilization, difficult depth control, low fertilizer utilization rate, root damage in tartary buckwheat planting, as well as the need for additional equipment for watering, inconvenient movement of existing equipment, and single function, realizing precise fertilization and efficient spraying, with convenient operation and reduced cost.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment:

[0029] Please refer to the attached Figure 1 - attached Figure 7 , the embodiment of the present invention provides a mobile automatic fertilization device for tartary buckwheat planting, as Figure 1As shown in the figure, it includes a base 1. The base 1 serves as the support foundation for the entire device, providing installation positions for other components. On one side of the top of the base 1, a gantry bracket 2 is fixedly installed. The gantry bracket 2 plays a key supporting and guiding role, providing a support structure for the movement of the cross frame 3. The cross frame 3 is movably installed in the middle of the gantry bracket 2. The cross frame 3 can move up and down under the constraint of the gantry bracket 2, thereby driving the liquid injection pipe 4 installed inside it to move. A number of liquid injection pipes 4 are evenly and movably installed inside the cross frame 3. The liquid injection pipe 4 is a key component for achieving precise fertilization. At the bottom end of each liquid injection pipe 4, a drill bit 5 is fixedly installed. The drill bit 5 plays an important role during the descent of the liquid injection pipe 4. By rotating, it can easily penetrate the soil, avoiding obstacles such as hard stones and hard soil blocks, ensuring that the liquid injection pipe 4 smoothly penetrates deep into the ground. A number of liquid injection holes 6 are opened on the outer diameter of the bottom of the liquid injection pipe 4. The fertilizer liquid will be discharged through these liquid injection holes 6 and directly injected under the buckwheat root system. Two openings 16 are opened on the upper surface of the base 1 near the gantry bracket 2. The openings 16 facilitate the liquid injection pipe 4 to pass through the base 1 and penetrate deep into the soil when descending. On the other side of the top of the base 1, a water and fertilizer integrated tank 17 is fixedly placed. The water and fertilizer integrated tank 17 is used to store the fertilizer liquid and irrigation water. Fertilizer liquid and irrigation water are respectively loaded on both sides inside it, realizing the integrated storage of fertilizer and water. A delivery pump 18 is fixedly installed on the top of the water and fertilizer integrated tank 17. The delivery pump 18 is responsible for pumping out the fertilizer liquid or clear water in the water and fertilizer integrated tank 17 and transporting it to the corresponding pipelines. On both sides of the top of the cross frame 3, U-shaped liquid passing seats 26 are fixedly installed. The U-shaped liquid passing seats 26 are important components for water flow transmission and realizing the swinging function of the spray head 41. On the other side of each U-shaped liquid passing seat 26, a bent pipe 28 is fixedly installed. The bent pipe 28 changes the water flow direction and introduces the water into the arc-shaped bent pipe 40. At the end of each bent pipe 28, an arc-shaped bent pipe 40 is fixedly installed. The arc-shaped bent pipe 40 further guides the water flow and enables the spray heads 41 to be evenly distributed below. A number of spray heads 41 are fixedly installed at the bottom end of the arc-shaped bent pipe 40. The spray heads 41 are used to spray water to realize the sprinkler irrigation operation.

[0030] In this embodiment, sleeves 7 are movably installed at positions corresponding to each liquid injection pipe 4 on the top wall of the gantry bracket 2. The sleeves 7 provide support and guidance for the rotation of the liquid injection pipe 4. On both sides of the upper part of the liquid injection pipe 4, splines 8 are fixedly installed. Key grooves 9 are opened on both sides inside the sleeves 7. The outer walls of the splines 8 are movably arranged inside the corresponding key grooves 9 on each side. Through the cooperation of the splines 8 and the key grooves 9, when the sleeves 7 rotate, the liquid injection pipe 4 can be driven to rotate synchronously.

[0031] Furthermore, a three-phase asynchronous motor 10 is fixedly installed in the middle of the top end of the gantry support 2. The three-phase asynchronous motor 10 serves as a power source to provide power for the lifting action of the fertilizing and liquid injection pipe 4 of the entire device. The driving end of the three-phase asynchronous motor 10 extends into the inside of the gantry support 2 and is fixedly installed with a driving shaft 11. The driving shaft 11 transmits the rotational power of the three-phase asynchronous motor 10. A threaded rod 12 is fixedly installed at the bottom end of the driving shaft 11, and the outer diameter of the threaded rod 12 is threadedly connected to the middle of the cross frame 3. When the driving shaft 11 rotates, it drives the threaded rod 12 to rotate. Since the threaded rod 12 is threadedly connected to the cross frame 3 and under the limiting effect of the gantry support 2, the rotation of the threaded rod 12 can drive the cross frame 3 to move up and down. A first driving gear 13 is fixedly installed on the outer diameter of the upper side of the driving shaft 11. First driven gears 14 are fixedly installed on the outer diameters of the upper sides of the sleeves 7. Transmission gears 15 are movably installed on both sides of the top wall of the gantry support 2. The adjacent first driving gear 13, first driven gear 14 and transmission gear 15 are all meshed and connected. Through this gear transmission structure, when the driving shaft 11 rotates, it drives the first driving gear 13 to rotate, and then drives the first driven gear 14 to rotate through the transmission gear 15, finally realizing the synchronous rotation of all the sleeves 7.

[0032] Furthermore, a U-shaped pipe 19 is fixedly installed above the water and fertilizer integrated tank 17, and both sides of the bottom of the U-shaped pipe 19 respectively extend to both sides inside the water and fertilizer integrated tank 17. The U-shaped pipe 19 is used to guide the fertilizer liquid and clear water on both sides of the water and fertilizer integrated tank 17 to the input end of the delivery pump 18. The input end of the delivery pump 18 is connected to the middle of the U-shaped pipe 19 through a pipeline, and a first reversing valve 20 is installed at the connection of the pipeline and the U-shaped pipe 19. The first reversing valve 20 can control the water flow direction and select whether to pump the fertilizer liquid or clear water into the subsequent pipeline.

[0033] Furthermore, the output end of the delivery pump 18 is fixedly installed with an infusion pipe 21. The infusion pipe 21 is used to transport the fertilizer liquid or clear water pumped out by the delivery pump 18 to the multi-way pipe 22. The output end of the infusion pipe 21 is fixedly connected to the middle of the multi-way pipe 22. The multi-way pipe 22 plays a role in shunting, evenly distributing the liquid transported by the infusion pipe 21 to each branch pipe 23. A number of branch pipes 23 are evenly installed at the bottom of the multi-way pipe 22, and the ends of the branch pipes 23 are respectively connected to the inside of the corresponding side liquid injection pipe 4. The branch pipes 23 transport the liquid shunted by the multi-way pipe 22 into the liquid injection pipe 4. Water delivery pipes 27 are fixedly installed on one side of each U-shaped liquid passing seat 26. The water delivery pipes 27 introduce the water in the infusion pipe 21 into the U-shaped liquid passing seat 26. The ends of the water delivery pipes 27 are all connected to the inside of the infusion pipe 21, and a second reversing valve 25 is fixedly installed at the connection. The second reversing valve 25 controls whether the water flow enters the water delivery pipe 27 to realize the switching between the fertilizing and watering functions.

[0034] Furthermore, rollers 24 are fixedly installed at the four corners of the bottom end of the base 1. The rollers 24 enable the device to move easily in the planting area, facilitating the operation of the staff. A handle 42 is fixedly installed on one side of the base 1. The handle 42 is convenient for the staff to hold and drag the device to move. A controller 43 is fixedly installed at the top of the handle 42. Through the controller 43, the staff can conveniently control the operation of devices such as the three-phase asynchronous motor 10 and the delivery pump 18, realizing a series of operations such as fertilization and watering.

[0035] Furthermore, a water wheel 29 is movably installed inside the U-shaped liquid passing seat 26 near one side of the bending pipe 28. The water wheel 29 rotates under the impact of the water flow, converting the kinetic energy of the water flow into mechanical energy. A transmission chamber 30 is fixedly connected to the middle of the U-shaped liquid passing seat 26. The transmission chamber 30 is used to install a series of transmission components to realize the transmission and conversion of power. The middle of the water wheel 29 extends into the interior of the transmission chamber 30 through a short shaft and a second driving gear 31 is fixedly installed. The rotation of the water wheel 29 drives the second driving gear 31 to rotate synchronously. A second driven gear 32 is movably installed on the lower side of one end of the inner side wall of the transmission chamber 30 near the water wheel 29, and the inner ends of the second driven gear 32 and the second driving gear 31 are meshed and connected. The rotation of the second driving gear 31 transmits the power through meshing with the second driven gear 32.

[0036] Furthermore, a worm 33 is fixedly installed in the middle of the second driven gear 32. The rotation of the second driven gear 32 drives the worm 33 to rotate. A transmission shaft 34 is movably installed in the middle of the transmission chamber 30. A worm gear 35 is fixedly installed on the outer diameter of the middle of the transmission shaft 34, and the inner ends of the worm gear 35 and the worm 33 are meshed and connected. The rotation of the worm 33 drives the transmission shaft 34 to rotate through meshing with the worm gear 35. Quarter bevel gears 36 are fixedly installed on the outer diameters of both sides of the transmission shaft 34, and the meshing teeth positions of the two quarter bevel gears 36 are staggered from each other. A rotating rod 37 is movably installed inside the U-shaped liquid passing seat 26 far from one side of the bending pipe 28. The end of the rotating rod 37 extends into the interior of the transmission chamber 30 and a transmission bevel gear 38 is fixedly installed. The outer end of the transmission bevel gear 38 is meshed with the inner ends of the two quarter bevel gears 36. Since the meshing teeth of the two quarter bevel gears 36 are staggered from each other, when the transmission shaft 34 rotates, the two quarter bevel gears 36 will intermittently mesh with the transmission bevel gear 38 to drive the rotating rod 37 to swing back and forth. One end of a U-shaped connecting rod 39 is fixedly installed on the outer diameter of the middle of the rotating rod 37, and the other end of the U-shaped connecting rod 39 is fixedly installed on the outer diameter of the bending pipe 28. The back-and-forth swing of the rotating rod 37 drives the bending pipe 28, the arc-shaped bent pipe 40 and the nozzle 41 to swing back and forth through the U-shaped connecting rod 39, improving the spraying range and spraying efficiency. At the same time, it can also clean the outer walls of the two injection pipes 4 to prevent the injection holes 6 from being blocked.

[0037] Working principle: First, move the device to the planting area. The operator holds the handle 42, and the rollers 24 at the four corners of the bottom end of the base 1 drive the device to move in the planting area. After reaching the fertilization point, the operator first starts the three-phase asynchronous motor 10 through the controller 43 at the top of the handle 42. The three-phase asynchronous motor 10 drives the drive shaft 11 to rotate. The drive shaft 11 drives the threaded rod 12 to rotate. The rotating threaded rod 12 meshes with the middle part of the cross frame 3. Under the limiting action of the gantry bracket 2, the cross frame 3 is driven to descend, thereby driving all the liquid injection pipes 4 to descend and making them extend into the ground through the opening 16 on the base 1. At the same time, when the drive shaft 11 rotates, it also drives the first driving gear 13 to rotate. Through the transmission of the first driving gear 13, the first driven gear 14 and the transmission gear 15, all the sleeves 7 are driven to rotate. Then, by the cooperation of the spline 8 and the keyway 9, all the liquid injection pipes 4 are driven to rotate, thereby driving the drill bit 5 at the bottom of the liquid injection pipe 4 to rotate. The continuously rotating drill bit 5 makes the descent process of the liquid injection pipe 4 smoother, avoiding interference from hard stones and hard soil blocks during the descent process. The descent height of the liquid injection pipe 4 is controlled by the three-phase asynchronous motor 10 to control the fertilization depth. Subsequently, start the delivery pump 18. The fertilizer liquid in the fertilizer and water integrated tank 17 is pumped out through the delivery pump 18. The fertilizer liquid first passes through the U-shaped pipe 19, enters the infusion pipe 21 under the control of the first reversing valve 20, and then is sent into the multi-way pipe 22, and then sent into each liquid injection pipe 4 through the branch pipe 23. The fertilizer liquid entering the infusion pipe 21 is discharged through the liquid injection holes 6 at the bottom of the liquid injection pipe 4, so that the fertilizer is directly injected below the buckwheat roots. This can not only enable the buckwheat roots to quickly absorb the fertilizer, reduce the volatilization of the fertilizer and water loss, improve the utilization rate of the fertilizer, but also does not dig pits and damage the roots, reducing the damage to the buckwheat capillary roots. After fertilization, the three-phase asynchronous motor 10 rotates in reverse to pull out all the liquid injection pipes 4 from the soil. Subsequently, start the delivery pump 18 again, and at the same time open the first reversing valve 20 and the second reversing valve 25 to pump out the clear water in the fertilizer and water integrated tank 17. The clear water passes through the U-shaped pipe 19 and the infusion pipe 21, enters the water delivery pipe 27 under the control of the second reversing valve 25, is sent into the two U-shaped liquid passing seats 26, and finally enters the arc-shaped elbow 40 through the bent pipe 28 and is sprayed out by all the nozzles 41 on the arc-shaped elbow 40 to realize the spraying and watering operation. Spraying can not only complete watering and increase air humidity, but also clean the leaves. At the same time, when the water source passes through the U-shaped liquid passing seat 26, it will drive the water wheel 29 to rotate. The water wheel 29 drives the second driving gear 31 to rotate. The rotating second driving gear 31 meshes with the second driven gear 32 to drive the worm 33 to rotate. The worm 33 meshes with the worm gear 35 to drive the transmission shaft 34 and the quarter bevel gears 36 on both sides of the transmission shaft 34 to rotate. Since the meshing teeth of the two quarter bevel gears 36 are staggered from each other, when the transmission shaft 34 rotates, the two quarter bevel gears 36 will intermittently mesh with the transmission bevel gear 38 to drive the rotating rod 37 to swing back and forth.By swinging the rotating rod 37 back and forth, one end of the U-shaped connecting rod 39 is driven to move accordingly, thereby driving the bent pipe 28, the arc-shaped bent pipe 40 and the nozzle 41 to swing back and forth, improving the spraying range and spraying efficiency. At the same time, the outer walls of the liquid injection pipes 4 on both sides can also be cleaned to prevent the liquid injection holes 6 from being blocked. After watering is completed, the staff can continue to drag the device to the next location to perform repeated fertilization and watering operations.
