Detailed Description
Hereinafter, an integrated liquid manure injection application and sowing machine according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the sizes, proportions and structural shapes of the components in the drawings are exemplary only and that the present invention is not limited thereto.
Fig. 1 is an overall schematic view showing a liquid manure injection application and sowing integrated tool according to an embodiment of the present invention, wherein a and B of fig. 1 show a rear view and a side view of the liquid manure injection application and sowing integrated tool, respectively. Fig. 2 shows a schematic perspective view of an integrated seeding and liquid manure application tool according to an embodiment of the invention.
As shown in fig. 1 and 2, the liquid manure injection application and seeding integrated tool 10 according to the embodiment of the present invention includes a liquid manure supply storage system 100, a liquid manure flow control system 200, a fertigation system 300, and a general control system (not shown). The liquid manure supply storage system 100, the liquid manure flow control system 200, the fertigation system 300, and the general control system can be mounted on a towing device such as a tractor. When the traction device moves at a preset speed in the operation area, the liquid manure supply storage system 100, the liquid manure flow control system 200 and the fertilizing and seeding system 300 are cooperatively operated under the control of the master control system, so that the automatic operation of seeding and liquid manure application can be realized.
The liquid manure supply storage system 100 is capable of extracting and storing liquid manure from the liquid manure pit. In addition, when it is required to apply liquid manure, the liquid manure supply and storage system 100 can quantitatively supply the stored liquid manure to the fertigation seeding system 300 of the next stage under the control of the liquid manure flow control system 200.
the liquid manure flow control system 200 is capable of controlling the supply flow rate of liquid manure from the liquid manure supply storage system 100 to match the supply amount of liquid manure to the actual demand of the sowing operation (e.g., speed of sowing, sowing amount, etc.).
the fertigation system 300 receives liquid manure from the liquid manure supply storage system 100 and distributes the liquid manure to the respective fertilization tubes. The fertilizing and seeding system 300 also has a furrowing device and a seeding device. The ditching device, the fertilizing tube and the seeding device work in a coordinated mode, so that the fertilizing operation can be implemented while ditching and seeding operation is carried out, and the integrated operation of seeding and liquid manure fertilization is achieved.
Hereinafter, the detailed structure and function of each part of the liquid dung-urine injection application and sowing integrated machine 10 according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the directions of front, rear, left, right, up, down, etc. are defined with reference to the traveling direction of the integrated liquid dung/urine injection and seeding machine 10 when it is mounted on the towing device for operation.
Liquid manure supply and storage system 100
Fig. 3 shows a perspective view of the liquid manure supply storage system 100 of the integrated liquid manure injection application and seeding tool 10 according to an embodiment of the invention.
The liquid manure supply storage system 100 includes a tank 101. The tank 101 may be fixed to a bracket of the towing device, and may contain and store liquid manure. The tank is provided with a first opening in fluid communication with a liquid inlet pipe 102, the liquid inlet pipe 102 being in fluid communication with a pump 103. The pump 103 is also in communication with the first extractor tube 104. The first extractor tube 104 may be provided with one or more valved extraction ports as desired. For example, as shown in fig. 3, the first drawing tube 104 extends along the rear and lower sides of the tank 101 and is connected to valved drawing ports 105 and 106 respectively located below the left and right sides of the tank 101. In this way, the liquid dung or urine can be extracted from any side according to the positional relationship between the liquid dung or urine pool and the liquid dung or urine injection/application and sowing integrated tool 10. When liquid dung or urine is extracted from the liquid dung or urine pool, the valve connected to one of the suction ports 105 or 106 of the liquid dung or urine pool is opened and the valve of the other suction port 106 or 105 is closed, and the liquid dung or urine flows into the tank 101 through the respective suction port 105 or 106, the first suction pipe 104, the pump 103 and the liquid inlet pipe 102, and finally from the first opening, under the driving of the pump 103.
Liquid manure usually contains a certain proportion of solid matter. The liquid manure stored in the tank 101 may generate solid precipitates during storage. In order to prevent such solid precipitation in the tank 101 and to allow the liquid manure to be applied in a uniformly mixed state, the liquid manure supply and storage system 100 may further have a function of stirring the liquid manure. As shown in fig. 3, the tank 101 is further provided with a second opening, the second opening is in fluid communication with a second extractor tube 107, and the second extractor tube 107 is in fluid communication with the first extractor tube 104 via a valve. Therefore, when the liquid dung and urine stirring operation is required, under the control of the general control system, the valves of the liquid pumping ports 106 and 105 are closed, the valve between the second liquid pumping pipe 107 and the first liquid pumping pipe 104 is opened, and the liquid dung and urine in the tank 101 flows into the second liquid pumping pipe 107 from the second opening and flows back to the tank 101 through the first liquid pumping pipe 104, the pump 103, the liquid inlet pipe 102 and the first opening under the driving of the pump 103, so that the circulating flow of the liquid dung and urine in the tank 101 is realized, and the liquid dung and urine stirring function is achieved.
In fig. 3, it is shown that the can 101 is provided with 4 first openings and 4 second openings, respectively, but the present invention is not limited thereto, and any number may be provided as needed. Further, in fig. 3, the first opening and the second opening are provided at opposite side walls (i.e., a front wall and a rear wall) of the can body, and the first opening is provided at an upper portion of the side wall of the can body 101 and the second opening is provided at a lower portion of the side wall of the can body 101. The first opening and the second opening are arranged in a manner that the circulating flow and the uniform stirring of the liquid dung and urine are facilitated. However, it should be understood that the arrangement positions and the relative positional relationships of the first openings and the second openings are not limited thereto. For example, the first opening and the second opening may be provided on the same side of the tank 101.
The inlet pipe 102 is also in fluid communication with a supply pipe 108 before the pump 103 is switched in, the supply pipe 108 being provided with a supply valve 109. The supply tube 108 is connected to a dispenser of a fertigation system 300 to be described hereinafter. The liquid supply valve 109 is normally kept closed and the liquid supply valve 109 is opened under the control of the general control system only when liquid manure fertilization is performed. When the liquid supply valve 109 is opened, under the action of the pump 103, a part of the liquid manure from the first liquid pumping pipe 104 is supplied to the distributor of the fertigation and seeding system 300 through the liquid supply valve 109 and the liquid supply pipe 108, and another part of the liquid manure still flows back to the tank 101 through the liquid inlet pipe 102 and the first opening, so that the circulating flow of the liquid manure in the tank 101 is maintained, and the liquid manure is uniformly mixed.
in the illustrated embodiment, the liquid manure is stirred by circulating the liquid manure. It should be understood that the present invention is not limited thereto. For example, a stirring shaft and a stirring impeller may be provided in the tank 101. The stirring impeller is driven by the motor to rotate around the stirring shaft, so that the liquid manure in the tank body 101 is uniformly mixed. In this case, the tank 101 may not be provided with the second opening and the second extractor tube 10 may be omitted. Further, in this case, the first opening of the can 101 is preferably provided at the lower side or bottom of the side wall of the can 101. Alternatively, the liquid manure supply and storage system 100 may not have a liquid manure stirring function, so as to reduce the cost. In both cases, when liquid manure is extracted from the manure pit, the liquid manure flows through a liquid inlet pipe in fluid communication with the first opening into the tank.
In addition, an example of drawing liquid manure from the pool through the drawing port of the first drawing tube 104 is shown. It should be understood that the first extractor tube 104 may also be provided without an extraction opening. In this case, an opening for pouring liquid manure can be provided directly on the tank. In addition, in the case where the tank is directly provided with an opening for pouring liquid dung or urine, the first liquid suction pipe 104, the second opening, and the second liquid suction pipe 107 may be omitted when the liquid dung or urine stirring function is not required.
Liquid manure flow control system 200
Fig. 4 is a schematic diagram illustrating a liquid manure flow control system 200 of the integrated liquid manure injection application and seeding tool 10 according to an embodiment of the present invention.
The liquid feces-urine flow control system 200 may include, for example, a display 201, a cpu 202, a speed sensor 203, and a flow control valve 204. The speed sensor 203 is provided near a moving mechanism of the traction device (e.g., a tractor tire as shown in the drawing), and senses a moving speed of the traction device to obtain speed data. The central processor 202 is fixed to the tank 101 or the carriage of the traction device. A flow regulating valve 204 is disposed in the supply pipe 108 downstream of the supply valve 109. The display unit 201 may be, for example, a display in a cab of the traction apparatus or a display on a remote controller of the traction apparatus. The display unit 201, the cpu 202, the speed sensor 203, and the flow rate control valve 204 are connected in communication by wireless or wired connection. Under the control of the central processor 202, the speed sensor 203 senses the traveling speed of the traction device and transmits the speed data to the display portion 201 for display. The speed data is also transmitted to the cpu 202, and the cpu 202 controls the opening and closing degree of the flow regulating valve 204 according to the corresponding relationship between the predetermined operation traveling speed and the liquid manure supply flow rate, so as to realize accurate control of the liquid manure supply flow rate. Further, the operator may manually set the degree of opening and closing of the flow rate adjusting valve 204 through the input device based on the speed displayed on the display unit 201, thereby accurately controlling the supply flow rate of the liquid dung or urine.
It should be understood that the display 201, the cpu 202 and the speed sensor 203 of the liquid fecal-urine flow control system 200 can also be integrated into a whole, and control the opening and closing of the flow control valve.
It should be understood that the liquid manure flow control system of the liquid manure injection application and seeding integrated tool according to the present invention may also be simplified to be provided with only the flow control valve 204. In this case, the operator sets the degree of opening and closing of the flow rate adjustment valve 204 in advance before each operation according to the current operation requirement.

As shown in FIG. 5, the fertigation system 300 includes a furrowing device 310 and a planting device 320, any suitable prior art, with the furrowing device 310 being located in front of the planting device 320. For example, as shown in FIGS. 5A and B, the furrowing device 310 is positioned in front of the seed planting device 320, e.g., hydraulically actuated, and the furrowing depth is adjustable. The sowing device 320 comprises a seed box 321 and a seeder 322, and the sowing depth of the seeder 322 can be adjusted. In the trench seeding operation, seeds stored in the seed box 321 can be placed by the seeder 322 at a predetermined depth in the soil after being trenched by the trenching apparatus 310, and then buried back into the soil.
the fertigation system 300 further comprises a distributor 301 connected to the liquid supply pipe 108 of the aforementioned liquid manure supply storage system 100 (see fig. 1 and 2 for connection of the distributor to the liquid supply pipe 108). The distributor 301 receives liquid manure from the supply pipe 108. The dispenser 301 is provided with at least one front dispensing tube 302 and at least one rear dispensing tube 303. The front distribution pipe 302 is connected to a hose for supplying liquid manure to a front fertilizer pipe 304 disposed near the furrowing device 310. The outlet end of the front fertilizing tube 304 is positioned at the tail end of the ditching device 310. In the ditching, seeding and fertilizing integrated operation, the front fertilizing tube 304 can apply liquid manure to the depth of the sown soil layer after ditching. The liquid manure applied through the pre-fertilization pipe 304 is generally used as a base fertilizer, is applied deeply, is used in a large amount, and is buried back in the soil together with the seeds after sowing, preventing the effective ingredients (e.g., ammonia gas) in the fertilizer from being volatilized. The rear distribution pipe 303 is connected to a hose to supply liquid manure to the rear fertilization pipe 305. The rear fertilizer pipe 305 extends to the rear of the liquid manure injection application and sowing integrated machine 10 to the vicinity of the ground so that its outlet end is located at the rear of the sowing device 320. Obviously, the position of the outlet end of the front fertilizer pipe 304 and the position of the outlet end of the rear fertilizer pipe 305 have a height difference in the vertical direction. The liquid manure applied through the post-fertilization pipe 305 is applied to the soil surface above the seeds after backfilling and pressing and permeates into the sowing trench, ensuring smooth seedling emergence of the seeds. The front fertilizing tube 304 and the rear fertilizing tube 305 are distributed front and back and layered up and down, so that a large amount of liquid dung and urine is applied, the volatilization of the liquid dung and urine can be avoided, and the seedling quality is ensured.
In fig. 5, there is shown an example in which a distributor 301 is provided with three front distribution pipes 302 and three rear distribution pipes 303, and accordingly, a fertigation system 300 is provided with three sets of a furrowing device 310, a sowing device 320, a front fertilization pipe 304, and a rear fertilization pipe 305. It should be understood that the present invention is not limited thereto, but may be arbitrarily set according to actual needs, as long as the number of the front distribution pipe 302, the rear distribution pipe 303, the furrowing device 310, the sowing device 320, the front fertilization pipe 304 and the rear fertilization pipe 305 are matched. In other words, the set of working components for carrying out the ditching, seeding and fertilizing integrated operation for a row of crops comprises at least a ditching device 310, a seeding device 320, a front fertilizing tube 304 and a rear fertilizing tube 305. N groups of the operation components can be arranged side by side according to requirements, so that the ditching, sowing and fertilizing integrated operation of n rows of crops can be simultaneously implemented. For example, n may preferably be 3 (as shown in the drawing) or 4.
The requirement of the sowing row spacing of different crops can be met by adjusting the arrangement spacing among the ditching devices 310, the sowing devices 320, the front fertilizing tubes 304 and the rear fertilizing tubes 305. The requirements of the sowing depth of different crops can be met by adjusting the ditching depth of the ditching device 310, the sowing depth of the sowing device 320 and the setting depth of the outlet end of the front fertilizing tube 304. In addition to the flow regulating valve 204 of the liquid manure flow control system 200, the front fertilizer pipe 304 and the rear fertilizer pipe 305 may be provided with valves respectively to regulate the flow of liquid manure in each fertilizer pipe. In addition, as shown in B of fig. 5, the height of the outlet end of the rear fertilizing tube 305 from the ground can be adjusted.
It should be understood that only the front distribution pipe 302 and the front fertilization pipe 304 or only the rear distribution pipe 303 and the rear fertilization pipe 305 may be provided, as desired. In this case, although the effects of the preferable structure of the front-back distribution and the vertical layering cannot be achieved, the basic integrated ditching, seeding and fertilizing operation can be achieved, and the cost of the facility can be reduced.
Next, a process of the ditching, seeding and fertilizing integrated operation of the integrated liquid manure injection and seeding machine 10 according to the embodiment of the present invention will be briefly described.
1) The operator performs measurement and analysis on the basic nutrient indexes of the applied liquid fecaluria and the soil to be operated, and determines the fertilizer and water application amount according to the conditions of crop production demand, liquid fecaluria fertility, soil fertility and the like.
2) Liquid manure is pumped from the manure pit into the tank, the amount of liquid manure poured generally not exceeding 90% of the maximum volume of the tank.
3) The fertilizer and water application amount, the traveling speed of the traction device and the opening and closing degree of the flow regulating valve are manually or automatically related.
4) seeds are put into the seed box, and the seeding device is manually or automatically set according to the seeding rate.
5) And starting the pump to stir the liquid excrement in the tank body, so as to ensure the uniformity of the liquid excrement.
6) The distance between the corresponding parts is adjusted according to the row spacing of the crops, and the ditching and sowing depth is adjusted according to the requirement.
