Description

Technical Field

[0001] The invention belongs to the technical field of water and fertilizer operation machines, and particularly relates to a wheel-type rotating quantitative irrigation water and fertilizer operation machine. Background Art

[0002] Water-fertilizer refers to fertilizer made from decomposed manure and urine plus water. It is usually in the form of a viscous slurry mixed with solids and liquids. Traditional water-fertilizer irrigation usually adopts the method of flooding. However, since sparse crops (corn, soybeans, sorghum, etc.) are planted with a certain distance between adjacent plants, large-scale water-fertilizer flooding will cause the water and fertilizer resources in the gaps to be wasted. At the same time, the indiscriminate flow of water and fertilizer will also affect the environment. Summary of the Invention

[0003] In order to solve the problems existing in the above-mentioned prior art and ensure the efficient and rapid operation of the fertilizing machinery, the present invention provides a wheel-type rotating quantitative water and fertilizer irrigation machine. Through the cooperation between the outer cylinder and the inner cylinder, and with the help of the cooperation relationship between the first feed port, the first discharge port, the second feed port, and the second discharge port, quantitative and intermittent water and fertilizer irrigation similar to the wheel type is realized, so that the operation machine can fertilize the spaced fertilizer pits while continuing to move forward. Water and fertilizer will not flow indiscriminately, and the operation can be fast and efficient while avoiding the waste of water and fertilizer resources and the impact on the environment.

[0004] The specific technical solution adopted in the present invention is:

[0005] A rotary quantitative water and fertilizer irrigation machine includes a work vehicle with a fertilizer storage tank, a liquid fertilizer pump, a frame and an irrigation mechanism are arranged in front of the work vehicle, the output end of the liquid fertilizer pump is provided with a feed pipe, the irrigation mechanism includes an inner cylinder and an outer cylinder sleeved with the inner cylinder, the inner cylinder and the outer cylinder are tightly matched, the inner cylinder is divided into a feed section and a discharge section at both ends, the side walls of the feed section and the discharge section are respectively provided with a first feed port and a first discharge port, the first feed port and the first discharge port are connected by a feed pipe located inside the inner cylinder, The outer cylinder is fixedly connected to the frame, and the side wall of the outer cylinder is provided with a second feed port and a second discharge port, the second feed port is located above the side wall of the outer cylinder and is connected to the feed pipe, the second discharge port is located below the side wall of the outer cylinder and is located on the same vertical plane as the first discharge port, the feed pipe, the first feed port and the second feed port are located on the same vertical plane, the inner cylinder has the freedom to rotate relative to the outer cylinder, the liquid fertilizer enters the feed pipe along the second feed port and the first feed port for storage, and the liquid fertilizer in the feed pipe flows out along the first discharge port and the second discharge port as the inner cylinder rotates.

[0006] The straight line where the first material inlet and the first material outlet are located is parallel to the straight line where the axis of the inner cylinder is located.

[0007] The perfusion mechanism also includes an adjusting device, which includes an adjusting airbag and a telescopic cylinder. An adjusting section is further provided inside the inner cylinder between the feeding section and the discharging section. The adjusting airbag is located in the adjusting section and is sleeved on the feeding pipe. The end of the discharging section of the inner cylinder extends out of the outer cylinder and has a tympanic membrane structure. The end of the discharging section of the inner cylinder is connected to the telescopic end of the telescopic cylinder. The end of the discharging section of the inner cylinder is convex or concave with the help of the telescopic cylinder and changes the pressure of the adjusting section. The adjusting airbag expands or contracts with the help of the pressure change of the adjusting section. The feeding pipe changes the flow rate of the liquid fertilizer with the help of the deformation of the adjusting airbag.

[0008] The end of the discharge section of the inner tube is provided with a horizontal tie rod ball head at the center, the telescopic end of the telescopic cylinder is provided with a bearing matching the tie rod ball head, and the end of the discharge section of the inner tube is connected to the telescopic end of the telescopic cylinder by means of the tie rod ball head.

[0009] The fixed end of the telescopic cylinder is fixedly connected to the frame, and bottom wheels are symmetrically provided at both ends of the perfusion mechanism. The bottom wheels are hinged to the frame, and the transmission shaft of the bottom wheel located on the feeding section side is connected to the center of the feeding section end of the inner cylinder.

[0010] One-way valves are respectively arranged on both sides of the regulating airbag on the feeding pipe, and the liquid fertilizer flows in one direction from the first feeding port to the first discharging port by means of the two sets of one-way valves.

[0011] The beneficial effects of the present invention are:

[0012] 1. In the present invention, a roulette-type quantitative supply of water and fertilizer is formed by the cooperation between the outer cylinder and the inner cylinder, with the help of the cooperation relationship between the first feed port, the first discharge port, the second feed port, and the second discharge port. During operation, when the first feed port and the second feed port coincide with each other, the water and fertilizer in the feed pipe will enter the feed pipe along the first feed port and the second feed port for storage. As the operating vehicle moves, the inner cylinder continues to rotate. When the inner cylinder rotates to the first discharge port and coincides with the second discharge port, the water and fertilizer stored in the feed pipe flows out along the second discharge port and forms a quantitative perfusion. Finally, the above process is repeated. Since the operating machine is always moving forward during the two discharges of water and fertilizer from the inner cylinder, the discharge positions are spaced at the same distance each time, thereby achieving a quantitative and intermittent water and fertilizer perfusion similar to a roulette-type, and enabling the operating machine to fertilize the interval fertilizer pits while continuing to move forward. The water and fertilizer will not flow indiscriminately, and the operation is fast and efficient while avoiding the waste of water and fertilizer resources and the impact on the environment.

[0013] 2. The feeding tube of the present invention is further provided with an adjusting airbag. When feeding, the telescopic cylinder is in a retracted state. At this time, the inner tube is in a state of maximum volume, the internal pressure is low, and the adjusting airbag is in an expanded state. The water and fertilizer can smoothly enter the feeding tube and flow toward the discharging section. When discharging, the telescopic cylinder is in an extended state. At this time, the inner tube is in a state of minimum volume, the internal pressure is high, and the adjusting airbag is in a contracted state. The adjusting airbag squeezes the feeding tube. The squeezing of the feeding tube causes the water and fertilizer inside to quickly flow out along the second discharging port, thereby preventing the relatively viscous water and fertilizer from being difficult to flow out of the feeding tube.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] Specific embodiments, such as Figure 1-8As shown, the present invention provides a wheel-type rotating quantitative water and fertilizer perfusion operation machine, including an operation vehicle 1 with a fertilizer storage tank, a liquid fertilizer pump 2, a frame 3 and a perfusion mechanism are arranged in front of the operation vehicle 1, and a feed pipe 4 is arranged at the output end of the liquid fertilizer pump 2. The perfusion mechanism includes an inner cylinder 5 and an outer cylinder 6 sleeved with the inner cylinder 5, and the inner cylinder 5 and the outer cylinder 6 are tightly matched. The inner cylinder 5 is divided into a feed section and a discharge section at both ends. The side walls of the feed section and the discharge section are respectively provided with a first feed port 7 and a first discharge port 8. The first feed port 7 and the first discharge port 8 are connected by a feed pipe 9 located inside the inner cylinder 5. The outer cylinder 6 is fixedly connected to the frame 3, and the side wall of the outer cylinder 6 is provided with a second feed port 10 and a second discharge port 11. The second feed port 10 is located above the side wall of the outer cylinder 6 and is connected to the feed pipe 4. The second discharge port 11 is located below the side wall of the outer cylinder 6 and is located on the same vertical plane as the first discharge port 8. The feed pipe 4, the first feed port 7 and the second feed port 10 are located on the same vertical plane. The inner cylinder 5 has the freedom to rotate relative to the outer cylinder 6. The liquid fertilizer enters the feed pipe 9 along the second feed port 10 and the first feed port 7 for storage. The liquid fertilizer in the feed pipe 9 flows out along the first discharge port 8 and the second discharge port 11 as the inner cylinder 5 rotates.

[0025] Since current water and fertilizer irrigation usually adopts flooding, but since there is usually a certain distance between adjacent crops when crops are planted, large-scale water and fertilizer flooding will cause the water and fertilizer resources in the gaps to be wasted, and the indiscriminate flow of water and fertilizer will also affect the environment.

[0026] Therefore, in the present invention, by the cooperation between the outer cylinder 6 and the inner cylinder 5, with the help of the cooperation between the first feed port 7, the first discharge port 8, the second feed port 10, and the second discharge port 11, a wheel-type quantitative supply of water and fertilizer is formed. When working, the liquid fertilizer pump 2 will draw the water and fertilizer in the fertilizer storage tank and enter the feed pipe 4, as shown in FIG. Figure 2 and Figure 4 As shown, when the first feeding port 7 and the second feeding port 10 coincide, the water and fertilizer in the feeding pipe 4 will enter the feeding pipe 9 along the first feeding port 7 and the second feeding port 10 for storage, and the inner cylinder 5 will continue to rotate as the working vehicle 1 moves. Figure 5 As shown, the first feed port 7 is closed by the side wall of the outer cylinder 6. At this time, since the inner cylinder 5 and the outer cylinder 6 are tightly fitted and the water fertilizer is in a slurry state, the water fertilizer stops feeding and does not enter the outer cylinder 6 or the inner cylinder 5. The working vehicle 1 continues to move forward. Figure 3 and Figure 7As shown, when the inner cylinder 5 rotates to the first discharge port 8 and coincides with the second discharge port 11, the water and fertilizer stored in the feed pipe 9 flows out along the second discharge port 11 and forms a quantitative perfusion, and finally the above process is repeated. Since the inner cylinder 5 is in the process of discharging water and fertilizer twice, the operating machine is always moving forward, so the position of each discharge will be spaced by the same distance, thereby realizing a quantitative and intermittent water and fertilizer perfusion similar to a wheel, and realizing the operating machine to fertilize the interval fertilizer pits in the process of continuous forward movement, and the water and fertilizer will not flow indiscriminately, while the operation is fast and efficient, the waste of water and fertilizer resources and the impact on the environment are avoided.

[0027] like Figure 2 As shown, the straight line where the first feed port 7 and the first discharge port 8 are located is parallel to the straight line where the axis of the inner cylinder 5 is located. Since the water and fertilizer are in a slurry state, its flow process requires a certain amount of time. By limiting the positions of the first feed port 7 and the first discharge port 8, it can be ensured that during the rotation of the inner cylinder 5, the water and fertilizer in the feed pipe 9 have sufficient time to flow from the first feed port 7 to the second feed port 10. If the first feed port 7 and the second feed port 10 are arranged one above and one below, that is, they match the positions of the second feed port 10 and the second discharge port 11 of the outer cylinder 6, when the water and fertilizer are fed into the first circle, due to the slow flow rate of the water and fertilizer, the water and fertilizer cannot flow out directly along the second discharge port 11. When it turns to the second circle, although the water and fertilizer in the feed pipe 9 can flow out, a large amount of water and fertilizer is still stored in the feed pipe 9 during feeding, resulting in a slow feeding speed in the second circle. Such reciprocating not only leads to low water and fertilizer perfusion efficiency, but also leads to uncertain amount of water and fertilizer perfusion each time, and quantitative perfusion cannot be formed.

[0028] like Figure 2-3As shown, the perfusion mechanism also includes an adjusting device, which includes an adjusting airbag 12 and a telescopic cylinder 13. An adjusting section is further provided inside the inner cylinder 5 between the feeding section and the discharging section. The adjusting airbag 12 is located in the adjusting section and is sleeved on the feeding pipe 9. The end of the discharging section of the inner cylinder 5 extends out of the outer cylinder 6 and has a tympanic membrane structure. The end of the discharging section of the inner cylinder 5 is connected to the telescopic end of the telescopic cylinder 13. The end of the discharging section of the inner cylinder 5 is convex or concave with the help of the telescopic cylinder 13 and changes the pressure of the adjusting section. The adjusting airbag 12 expands or contracts with the help of the pressure change of the adjusting section. The feeding pipe 9 changes the flow rate of the liquid fertilizer with the help of the deformation of the adjusting airbag 12. In order to allow the feeding pipe to The water and fertilizer in 9 can quickly flow out of the second discharge port 11. The feeding pipe 9 of the present invention is further provided with an adjusting airbag 12. When feeding, the telescopic cylinder 13 is in a retracted state. At this time, the inner tube 5 is in a state of maximum volume, the internal pressure is small, and the adjusting airbag 12 is in an expanded state. The water and fertilizer can smoothly enter the feeding pipe 9 and flow toward the discharge section. When discharging, the telescopic cylinder 13 is in an extended state. At this time, the inner tube 5 is in a state of minimum volume, the internal pressure is large, and the adjusting airbag 12 is in a contracted state. The adjusting airbag 12 squeezes the feeding pipe 9. The squeezing of the feeding pipe 9 will cause the water and fertilizer inside to quickly flow out along the second discharge port 11, thereby preventing the more viscous water and fertilizer from being difficult to flow out of the feeding pipe 9.

[0029] like Figure 2-3 As shown, the end of the discharge section of the inner cylinder 5 is provided with a horizontal tie rod ball head 14 at the center, and the telescopic end of the telescopic cylinder 13 is provided with a bearing 15 matching the tie rod ball head 14. The end of the discharge section of the inner cylinder 5 is connected to the telescopic end of the telescopic cylinder 13 by means of the tie rod ball head 14. The inner cylinder 5 is constantly rotating, and the fixed end of the telescopic cylinder 13 is in a fixed state, which will cause the end of the discharge section of the inner cylinder 5 and the telescopic end of the telescopic cylinder 13 to always generate rotational friction, which can easily cause the end of the discharge section of the inner cylinder 5 to be worn or even penetrated by the telescopic cylinder 13. Therefore, a tie rod ball head 14 is added between the inner cylinder 5 and the telescopic cylinder 13. Due to the presence of the tie rod ball head 14, the telescopic end of the telescopic cylinder 13 will not directly contact the end of the discharge section of the inner cylinder 5, thereby avoiding wear on the surface of the inner cylinder 5.

[0030] like Figure 8 As shown, the fixed end of the telescopic cylinder 13 is fixedly connected to the frame 3, and bottom wheels 16 are symmetrically provided at both ends of the perfusion mechanism. The bottom wheels 16 are hinged to the frame 3, and the transmission shaft of the bottom wheel 16 located on one side of the feeding section is connected to the center of the feeding section end of the inner cylinder 5, wherein the outer cylinder 6 is a cylindrical structure with both ends open. The bottom wheel 16 connected to the inner cylinder 5 is used to drive the inner cylinder 5 to rotate, and the bottom wheel 16 on the other side plays a role in balancing the working machine as a whole.

[0031] like Figure 2-3As shown, the feed pipe 9 is provided with a one-way valve 17 on both sides of the regulating airbag 12. The liquid fertilizer flows in one direction from the first feed port 7 to the first discharge port 8 with the help of two sets of one-way valves 17. In order to prevent the backflow of water and fertilizer, the present invention is further provided with a one-way valve 17, wherein the feed pipe 9 is a bowl-shaped inverted arch structure. When feeding, the water and fertilizer flow downward and pass through the first one-way valve 17 and are stored in the regulating section. As the inner cylinder 5 rotates to the discharging state, the feed pipe 9 flips to a positive arch structure. At this time, due to the presence of the one-way valve 17 in the feeding section, the water and fertilizer cannot flow back and can only flow out along the discharge section, thereby ensuring the accuracy of each discharge and realizing quantitative perfusion of water and fertilizer.
