Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, and in particular to a water-fertilizer integrated irrigation device for agricultural planting. Background Art

[0002] Integrated water and fertilizer irrigation equipment is an agricultural equipment that combines irrigation and fertilization functions. It provides precise water and fertilizer supply by mixing water and fertilizer and evenly delivering them to the roots of crops. This equipment can automatically adjust the water and fertilizer ratio and supply according to the water and fertilizer requirements of crops, improve the efficiency of irrigation and fertilization, and reduce resource waste and environmental pollution.

[0003] After searching, the Chinese patent with announcement number CN113853914B includes a base plate, the upper end surface of the base plate is fixedly connected to a water tank, the upper end surface of the water tank is fixedly connected to a stirring device, a water inlet pipe and a dosing device, the stirring device includes an air pipe, an air-tight connecting pipe, a fixed plate, an air blowing pipe, a sliding groove, an aeration connecting pipe, an aeration disk, a spring, a water trough, a positioning column and an air pump, one end of the air-tight connecting pipe is fixedly connected to the upper end surface of the fixed plate, one end of the air pipe is fixedly connected to the end of the air-tight connecting pipe away from the fixed plate, the other end of the air pipe is fixedly connected to the upper end surface of the air pump, one end of the air blowing pipe is fixedly connected to the lower end surface of the fixed plate, the other end of the air blowing pipe is slidably connected to the inside of the aeration connecting pipe, and the sliding groove is provided on the side end surface of the aeration connecting pipe. The above patent effectively improves the fertilization effect, and at the same time can adjust the water and fertilizer concentration at any time, and ensures that the nozzle will not be blocked during fertilization.

[0004] However, in the process of adjusting the water and fertilizer concentrations in the above-mentioned patent, the changes in the water and fertilizer concentrations cannot be displayed intuitively and need to be judged based on manual experience. To increase the water and fertilizer concentrations, it is necessary to use a dosing device to suck the well-proportioned fertilizer solution and inject it into the water tank, while to reduce the water concentration, it is necessary to stop dosing and inject water into the water tank. The operation process is cumbersome and prone to concentration errors. If the concentration does not meet the standard, it is difficult to achieve the expected sprinkler irrigation effect, and excessive concentration will cause crop burns. On the other hand, during the sprinkler irrigation process, when the water and fertilizer are used up, they need to be re-proportioned, and the degree of automation of the equipment is low.

[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.

[0020] Embodiment 1:

[0021] See also Figures 1 to 9 , the present invention provides a technical solution: An integrated irrigation device for agricultural planting with water and fertilizer comprises a base 1 and a control component inside the base 1, a batching component connected to the control component in a transmission manner, and an adjustment component connected to the batching component in a transmission manner, wherein a treatment tank 11 is fixedly connected to the upper surface of the base 1, an extension plate 12 is fixedly connected to one side of the top of the treatment tank 11, a one-way pipe 13 is passed through and fixedly connected to the outer contour of the side of the base 1, and the conducting direction of the one-way pipe 13 is set from top to bottom, a liquid spraying pipe 14 is passed through and fixedly connected to the outer contour of the middle section of the base 1, a feed port 15 is opened on one side of the bottom end of the base 1, and a cover plate adapted to the feed port 15 is clamped in the feed port 15; The control assembly includes a positioning mechanism for pulling the device forward and backward and a traveling mechanism for completing the travel of the device and starting the work synchronously. The positioning mechanism is connected to the base 1 in a limited sliding manner. The traveling mechanism is located inside the base 1 and is connected to the positioning mechanism in a transmission manner. The batching assembly includes a mixing mechanism that is driven by a traveling mechanism to complete the fertilizer-liquid mixing operation and a transmission mechanism that synchronously completes the water addition. The mixing mechanism is transmission-connected to the traveling mechanism, and the transmission mechanism is transmission-connected to the mixing mechanism.

[0022] In this device, the base 1 and the processing tank 11 together constitute the main structure of the device, the extension plate 12 provides a support basis for the adjustment component, the one-way pipe 13 connects the upper and lower ends of the inside of the processing tank 11 and the flow direction is set from top to bottom, and the spray pipe 14 specifically adopts a Laval spray pipe, which can realize the accelerated spraying of water and fertilizer and the range can be freely adjusted. Its principle is the existing technology and will not be repeated here. The addition of fertilizer is completed through the feed port 15 and the cover plate adapted thereto.

[0023] The moving direction of the equipment is controlled by pushing and pulling the positioning mechanism. At the same time, the moving mechanism synchronously drives the subsequent components, and the transmission connection mode inside the equipment is different for different moving directions. Furthermore, the mixing mechanism synchronously starts the water-fertilizer ratio and pressurization work.

[0024] Under the control of the regulating component, the transmission mechanism starts water-fertilizer ratio and pressurization work synchronously, and the regulating component can freely control the running speed of the transmission mechanism, thereby realizing the regulation and control of water-fertilizer concentration.

[0025] Embodiment 2:

[0026] See also Figure 3-Figure 5 This embodiment further illustrates the following on the basis of the first embodiment: The positioning mechanism includes a handle 2 for manually pushing and pulling the control device to move forward, the bottom end of the handle 2 is penetrated and fixedly connected with a positioning pin 21 extending to both sides, both ends of the positioning pin 21 are fixedly connected with a connecting spring 22, the ends of the two connecting springs 22 away from the positioning pin 21 are fixedly connected with a fixing pin 23, and the fixing pin 23 is fixedly connected to the inside of the base 1, and the bottom end of the handle 2 is fixedly connected with a positioning rod 24.

[0027] The travel mechanism includes a driving shaft 3 that penetrates and is rotatably connected to a positioning rod 24, both ends of the driving shaft 3 are fixedly connected to a driving wheel 31, both ends of the driving shaft 3 are penetrated by and rotatably connected to a fixing rod 32 at a position near the driving wheel 31, the other ends of the two fixing rods 32 are penetrated by and rotatably connected to the same driven shaft 33, both ends of the driving shaft 3 are penetrated by and fixedly connected to a pulley 1 34 at a position near the fixing rod 32, both ends of the driven shaft 33 are penetrated by and fixedly connected to a pulley 2 35, a chain 36 is transmission-connected to the outer contour of the pulley 1 34, and the other end of the chain 36 is sleeved on the outer contour of the pulley 2 35 on the same side, and positioning plates 37 are rotatably connected to the opposite back surfaces of the middle sections of the two fixing rods 32 through pins.

[0028] The travel mechanism further includes a follower shaft 38 that penetrates through and is rotationally connected to the base 1 at a side away from the handle 2 , and both ends of the follower shaft 38 are fixedly connected to follower wheels 39 .

[0029] When the handle 2 is pushed or pulled manually, the handle 2 squeezes the positioning pin 21 and the base 1 moves synchronously, causing the device to tend to move. At this time, the movement trend of the base 1 further causes the degree of engagement between the positioning plate 37 and the ground to gradually increase, thereby causing the positioning plate 37 to deflect. As a result, in the early stage of the device's movement, it is resisted by the positioning plate 37, so that when the handle 2 is pushed or pulled, it is necessary to overcome the pressure between the positioning plate 37 and the ground, thereby realizing the reverse self-locking function of the device.

[0030] And when pushing and pulling the handle 2, due to the clamping relationship between the positioning plate 37 and the ground, the travel mechanism is in a state of being unable to move. Then, the squeezing of the positioning pin 21 and the handle 2 by the handle 2 will cause the relative position between the positioning pin 21 and the fixing pin 23 to change. At this time, the connecting spring 22 is synchronously compressed and released. The release of the connecting spring 22 causes the positioning pin 21 to be restricted to the maximum stroke on both sides of the fixing pin 23. This position corresponds to the working position of the device when moving forward and backward, so that when pushing and pulling the handle 2, the positioning mechanism automatically adjusts its working position according to the force direction.

[0031] Furthermore, manually pushing and pulling the handle 2 will drive the entire device to move synchronously. When the device moves forward, the driving wheel 31 drives the fixed rod 32 and the pulley 1 34 to rotate synchronously, and the pulley 1 34 drives the chain 36, the pulley 2 35 and the driven shaft 33 to rotate synchronously. At this time, the mixing mechanism and the worm sleeve 41 on the driving shaft 3 are meshed with each other and are connected in transmission. The device starts to move forward and pressurizes and sprays the proportioned water and fertilizer to complete the irrigation operation; when the device moves backward, the driving wheel 31 drives the fixed rod 32, the pulley 1 34, the chain 36, the pulley 2 35 and the driven shaft 33 to rotate in the opposite direction. At this time, the mixing mechanism and the worm sleeve 41 on the driven shaft 33 are meshed and connected in transmission. The device starts to move backward and completes the automatic proportioning operation of water and fertilizer according to the set concentration.

[0032] It should be noted that the rotation radius of pulley one 34 is set to be much larger than the rotation radius of pulley two 35. Then, in the process of pulley one 34 and pulley two 35 being connected by chain 36 to make their linear speeds the same, the angular velocity of pulley two 35 is much larger than the angular velocity of pulley one 34, that is, the rotation speed of the worm sleeve 41 located on the driven shaft 33 is much larger than the rotation speed of the worm sleeve 41 located on the driving shaft 3; thereby, when the equipment is retreating, the operating speed of the mixing mechanism is much larger than the working speed when the equipment is advancing; and because the two worm sleeves 41 have opposite rotation directions and are located on both sides of the mixing mechanism, that is, the mixing mechanism rotates in opposite directions when meshing with the two worm sleeves 41, thereby ensuring the reciprocating compression spraying and water-fertilizer matching of the mixing mechanism, and the travel distance to complete the water-fertilizer matching when the equipment is retreating is much smaller than the spraying irrigation stroke when the equipment is advancing, thereby ensuring the effective utilization rate of the equipment.

[0033] Embodiment three:

[0034] See also Figure 6-Figure 7 This embodiment further illustrates the following on the basis of the second embodiment: The mixing mechanism includes a worm wheel 4 which is connected to the inside of the base 1 for limited rotation. Both sides of the worm wheel 4 are intermittently meshed and transmission-connected with worm sleeves 41, and the worm sleeves 41 are respectively fixedly connected to the outer contours of the driving shaft 3 and the driven shaft 33. The rotation directions of the two worm sleeves 41 are opposite. A threaded shaft 43 is screwed at the axis of the worm wheel 4, and the threaded shaft 43 penetrates and extends to the inside of the processing tank 11. A limiting block 44 is clamped on the outer contour of the bottom end of the threaded shaft 43, and the other end of the limiting block 44 is fixedly connected to the inside of the base 1. A stirring blade 45 is fixedly connected to the outer contour of the middle section of the threaded shaft 43. A compression plate 46 is fixedly connected to the top of the threaded shaft 43. A one-way valve 47 is provided on the surface of the compression plate 46, and the conducting direction of the one-way valve 47 is set from bottom to top. The one-way valve 47, the compression plate 46 and the stirring blade 45 are all located at the bottom of the processing tank 11.

[0035] The mixing mechanism further comprises a gear set 42 which is rotationally connected to the inside of the base 1 in a limited manner, and the input end of the gear set 42 is fixedly connected to the bottom end of the worm gear 4 , and the output end of the gear set 42 is penetrated and fixedly connected with a transmission shaft 48 .

[0036] The transmission mechanism includes a threaded ring 6 that penetrates and is limitedly rotatably connected to the top axis of the processing tank 11, a threaded shaft 61 is screwed on the inner contour of the threaded ring 6, and the threaded shaft 61 extends into the inside of the processing tank 11, a limiting block 62 is clamped on the outer contour of the threaded shaft 61, and the other end of the limiting block 62 is fixedly connected to the inner wall of the processing tank 11, and a compression plate 63 is fixedly connected to the bottom end of the threaded shaft 61, and a one-way valve 64 is provided on the surface of the compression plate 63, and the conduction direction of the one-way valve 64 is set from top to bottom.

[0037] It should be noted that the interior of the treatment tank 11 is divided into three areas of unequal volume by the compression plate 2 63 and the compression plate 1 46. The upper area in the treatment tank 11 is a water storage area with the largest volume, into which water can be injected by an external water pump. The middle area in the treatment tank 11 is a water-fertilizer mixing area, and the liquid spray pipe 14 is connected to this area to realize the water-fertilizer sprinkler irrigation operation. The lower area in the treatment tank 11 is a fertilizer liquid mixing area with the smallest volume. The feed port 15 is connected to this area to realize the fertilizer addition operation. Fertilizer is injected into the lower area in the treatment tank 11 by opening and closing the cover plate of the feed port 15. At this time, the water in the upper area of ​​the treatment tank 11 naturally flows into the lower area of ​​the treatment tank 11 through the one-way pipe 13 and mixes with the fertilizer to form fertilizer liquid.

[0038] It should be noted that the fertilizer concentration in the fertilizer solution is at the maximum saturation state and there is excess precipitation. Direct use for crop irrigation will cause crop burns. Therefore, the fertilizer solution needs to be further diluted through subsequent water-fertilizer mixing operations to meet the irrigation needs of the crops.

[0039] When the equipment moves forward and starts the sprinkler operation, the worm wheel 4 meshes with the worm sleeve 41 on the drive shaft 3. At this time, the drive shaft 3 drives the worm sleeve 41, the worm wheel 4 and the input end of the gear set 42 to rotate synchronously, while the threaded shaft 43 cannot rotate due to the clamping and limiting effect of the limit block 44, that is, the threaded shaft 43 is in a slowly rising state due to the screw connection of the worm wheel 4; further, the one-way valve 47, the compression plate 46 and the stirring blade 45 all rise slowly and synchronously with the threaded shaft 43 inside the treatment tank 11, and the conduction direction of the one-way valve 47 is set from bottom to top. At this time, the compression plate 46 begins to compress the internal space of the treatment tank 11 upward.

[0040] Similarly, the rotation of the worm gear 4 drives the transmission mechanism to move synchronously through the motion transmission of the gear set 42 and the adjusting assembly. At this time, the threaded ring 6 starts to rotate and tends to drive the threaded shaft 2 61 to rotate synchronously, and the threaded shaft 2 61 is limited by the clamping rotation of the limit block 2 62. At this time, the threaded shaft 2 61 begins to extend downward synchronously under the influence of the threaded connection of the threaded ring 6, and since the conduction direction of the one-way valve 2 64 is set from top to bottom, the compression plate 2 63 synchronously compresses the internal space of the processing tank 11 downward at this time.

[0041] Furthermore, the internal space in the middle section of the processing tank 11 is continuously reduced due to the double compression of the compression plate 2 63 and the compression plate 1 46, and the water and fertilizer stored in the middle section of the processing tank 11 are sprayed out along the spray pipe 14. When the water and fertilizer pass through the spray pipe 14, the flow path becomes smaller, thereby accelerating the spraying to complete the irrigation operation.

[0042] It should be noted that the number of thread turns of the threaded shaft 43 is set to be much larger than the number of thread turns of the threaded shaft 61, so that when the compression plate 2 63 and the compression plate 1 46 synchronously compress the internal space of the processing tank 11, there is a stroke difference between the compression plate 2 63 and the compression plate 1 46, and the descending stroke of the compression plate 2 63 is much larger than the ascending stroke of the compression plate 1 46.

[0043] Furthermore, when the equipment moves backward, the worm gear 4 meshes with the worm sleeve 41 on the driven shaft 33. At this time, the rotation rate of the worm gear 4 is significantly greater than the rotation rate of the worm gear 4 when the equipment moves forward, which causes the threaded shaft 43 to drive the stirring blade 45, the compression plate 46 and the one-way valve 47 to descend at a rate much greater than the rate when they rise. The total lifting stroke of the threaded shaft 43 is limited to a fixed value by its thread length and the worm gear 4, so that the threaded shaft 43 can run to the extreme position faster when descending, thereby reducing the stroke amount when the equipment moves backward to complete the water-fertilizer mixing.

[0044] It should be noted that, as the stirring blades 45 rise and fall with the threaded shaft 43 in the lower area of ​​the processing tank 11, they can fully stir the surrounding precipitated fertilizer to promote its dissolution, thereby ensuring that the fertilizer solution concentration in the lower area of ​​the processing tank 11 is always in a maximum saturated state.

[0045] At this time, the compression plate 1 46 moves downward inside the treatment tank 11 and the compression plate 2 63 moves upward inside the treatment tank 11, resulting in an increase in the effective space volume in the middle section of the treatment tank 11. Furthermore, at this time, the water located in the upper part of the treatment tank 11 is pressed into the middle section of the treatment tank 11 through the one-way valve 2 64, and the fertilizer liquid located at the bottom of the treatment tank 11 is synchronously pressed into the middle section of the treatment tank 11 through the one-way valve 1 47, and the amount of water and fertilizer liquid pressed in is the lifting and lowering stroke of the compression plate 2 63 and the compression plate 1 46.

[0046] In one of the embodiments, the irrigation requirement of the crop is a water-fertilizer concentration of 1:150, and the ratio of the number of thread turns of the threaded shaft 1 43 to that of the threaded shaft 2 61 is set to 100:1, that is, the ratio of the lifting stroke of the compression plate 2 63 and the compression plate 1 46 is also 100:1. When the compression plate 1 46 descends and presses 1 unit of fertilizer liquid into the middle area of ​​the processing tank 11 through the one-way valve 1 47, the compression plate 2 63 rises synchronously and presses 100 units of water into the middle area of ​​the processing tank 11 through the one-way valve 2 64. Furthermore, the fertilizer liquid and the water are mixed in proportion in the middle area of ​​the processing tank 11 and sprayed out through the spray pipe 14 to complete the irrigation operation. When a single crop is sprayed, the water-fertilizer concentration in the equipment remains unchanged and is in a set state.

[0047] Embodiment 4:

[0048] See also Figure 7-Figure 8 This embodiment further illustrates the following on the basis of the second embodiment: The adjusting assembly includes a driving cone wheel 5 that passes through and is fixedly connected to the outer contour of the top end of the transmission shaft 48, and a driving cone wheel 51 that is fixedly connected to the top end of the threaded ring 6. The outer contours of the middle sections of the driving cone wheel 5 and the driving cone wheel 51 are connected with a driving belt 52 for transmission. The top end of the extension plate 12 passes through and is connected with an adjusting shaft 53 for limited rotation. The middle section of the adjusting shaft 53 is threadedly connected to a limiting wheel 54, and the limiting wheel 54 and the driving belt 52 are limitedly engaged. Both sides of the limiting wheel 54 are penetrated and slidably connected with a fixed shaft 55, and the fixed shaft 55 is fixedly connected to the upper surface of the extension plate 12.

[0049] Furthermore, when it is necessary to adjust the water and fertilizer concentration for different crops, the operator rotates the adjusting shaft 53. At this time, the adjusting shaft 53 tends to drive the limiting wheel 54 to rotate synchronously, while the limiting wheel 54 is restricted by the fixed shaft 55 and cannot rotate, that is, the limiting wheel 54 begins to rise and fall under the screw connection of the adjusting shaft 53; further, the limiting wheel 54 pulls the transmission belt 52 to rise and fall synchronously on the surfaces of the driving cone wheel 5 and the transmission cone wheel 51. Since the driving cone wheel 5 and the transmission cone wheel 51 are both cone wheels and are staggered, that is, the transmission ratio between the driving cone wheel 5 and the transmission cone wheel 51 is affected by the position change of the transmission belt 52. When the transmission belt 52 is in the middle position of the driving cone wheel 5 and the transmission cone wheel 51, the transmission ratio between the driving cone wheel 5 and the transmission cone wheel 51 is 1:1.

[0050] When the limiting wheel 54 pulls the transmission belt 52 downward, the rotation radius of the driving cone wheel 5 increases and the rotation radius of the transmission cone wheel 51 decreases, and the linear speeds of the driving cone wheel 5 and the transmission cone wheel 51 are always the same due to the transmission action of the transmission belt 52, and the rotation rate of the driving cone wheel 5 is affected by the transmission action of the transmission shaft 48 and depends on the travel rate of the equipment, that is, at this time the rotation rate of the driving cone wheel 5 remains unchanged while the rotation rate of the transmission cone wheel 51 increases, further, the transmission cone wheel 51 drives the rotation rate of the threaded ring 6 to increase, and the lifting and lowering rate of the threaded shaft 61 increases synchronously.

[0051] It can be seen from Example 3 that the increase in the lifting and lowering rate of the threaded shaft 61 means that the lifting and lowering stroke difference between the compression plate 63 and the compression plate 1 46 increases synchronously per unit time. Based on the ratio of the number of thread turns of 100:1 between the threaded shaft 43 and the threaded shaft 61, the ratio of the initial lifting and lowering stroke of the compression plate 63 and the compression plate 1 46 per unit time is 100:1. At this time, as the lifting and lowering rate of the threaded shaft 61 further increases, the ratio of the lifting and lowering stroke of the compression plate 2 63 and the compression plate 1 46 per unit time will further increase, thereby causing the ratio of the water body and the fertilizer liquid injected into the middle area of ​​the treatment tank 11 per unit time to increase synchronously, and the water-fertilizer ratio concentration will further decrease.

[0052] Similarly, when the adjusting shaft 53 is rotated to drive the limiting wheel 54 and the transmission belt 52 to rise, the rotation rate of the threaded shaft 61 decreases, and the ratio concentration of water and fertilizer increases synchronously, so that the water and fertilizer concentration in the equipment can be freely adjusted by simply rotating the adjusting shaft 53 forwards and backwards, and the adjusting shaft 53 is self-locking when it is not rotated by external force, further ensuring that the set water and fertilizer concentration will not have an offset error during the operation of the equipment.

[0053] In one of the embodiments, since the irrigation demand of most crops is in the range of 1:50-1:300, the ratio of the radius of the two ends of the driving cone wheel 5 and the transmission cone wheel 51 is set to 1:3, that is, when the transmission belt 52 moves to the lowest end of the driving cone wheel 5 and the transmission cone wheel 51, the ratio of the lifting and lowering rates of the threaded shaft 2 61 and the threaded shaft 1 43 is 33:1, and when the transmission belt 52 moves to the top of the driving cone wheel 5 and the transmission cone wheel 51, the ratio of the lifting and lowering rates of the threaded shaft 2 61 and the threaded shaft 1 43 is 300:1, that is, the water and fertilizer concentration setting interval of the equipment is 1:33-1:300, which can meet the irrigation needs of most crops.

[0054] It should be noted that when the equipment moves forward for sprinkling irrigation, the compression plate 1 46 and the compression plate 2 63 move toward each other to squeeze the middle area in the processing tank 11 to complete the water and fertilizer spraying. Along with the gradual movement of the compression plate 1 46 and the compression plate 2 63, the compression plate 1 46 and the compression plate 2 63 gradually contact and squeeze. At this time, the compression plate 1 46 and the compression plate 2 63 cannot move further, causing the threaded ring 6 and the worm gear 4 to be stuck and stop rotating. The equipment cannot move forward at this time, thereby reminding the personnel that the well-proportioned water and fertilizer in the processing tank 11 have been used up and the equipment needs to be controlled to retreat for re-addition; at the same time, when the equipment retreats, the compression plate 1 46 and the compression plate 2 63 move relative to each other. When one of the threaded shaft 2 61 and the threaded shaft 1 43 reaches the limit position first, the threaded ring 6 and the worm gear 4 are also stuck and stop rotating. At this time, the equipment cannot move backward, thereby reminding the personnel that the proportioning and adding of water and fertilizer has been completed.
