Description

Technical Field

[0001] The invention relates to the technical field of ecological agricultural seedling cultivation, and in particular to an intermittent water-saving irrigation and weeding device for ecological agriculture. Background Art

[0002] As a sustainable agricultural development model, ecological agriculture emphasizes the coordinated development of agricultural production and ecological protection under the premise of protecting and improving the agricultural ecological environment. With the continuous improvement of people's awareness of ecological environmental protection and the increasing attention to the quality and safety of agricultural products, the importance of ecological agriculture has become increasingly prominent. In the planting process of ecological agriculture, mobile irrigation devices are required, including sprinkler mobile irrigation devices, drip mobile irrigation devices and micro-sprinkler mobile irrigation devices.

[0003] The existing mobile irrigation device requires an electric drive device to drive the water pump inside for spraying irrigation. The electric drive device is nothing more than a battery or an external cable installed on the device for power supply. Since the seedling breeding range is large, if the external cable is used for power supply, the cable needs to be adjusted during the back and forth irrigation process, which makes irrigation inconvenient. In addition, the battery method is prone to power shortage during long-term irrigation of large-scale agricultural planting. If a large-capacity battery is added for this purpose, the weight of the mobile irrigation device will increase, which is prone to problems such as poor mobility and inconvenience in transportation in the seedling breeding site. The poor mobility is mainly due to the loose soil in the ridges and ditches of the breeding site, which will cause the wheels of the mobile device to sink into the soil. Summary of the invention

In addition, direct watering on the roots of the seedlings can avoid a large amount of water loss in the process of reaching the roots of the seedlings; By spraying water and fertilizer from the bottom of the movable tube to the roots of the seedlings, the roots of the seedlings can be fertilized. Fertilizing the roots of the seedlings can allow the roots of the seedlings to absorb nutrients in the fertilizer more quickly, and the roots of the seedlings can absorb and utilize nutrients more efficiently, reducing fertilizer waste. By spraying the herbicide from the bottom of the movable tube to around the roots of the seedlings, the weeds around the seedlings can be effectively killed. Compared with large-area spray weeding, this method is more targeted. For some special environments that are difficult to weed with mechanical or manual weeding, such as some flower seedling bases with complex terrain, the herbicide is placed in a small area around the roots. It can effectively control the growth of weeds and ensure the quality of the seedlings without damaging the seedlings. BRIEF DESCRIPTION OF THE DRAWINGS

A piston rod 57 is slidably connected inside the capillary of the hydraulic tube 56. The piston rod 57 is composed of a disc plug and a straight rod. Hydraulic oil is stored in the space inside the hydraulic tube 56 and between the piston rod 57 disc plug and the piston plate 55. One end of the straight rod of the piston rod 57 that passes through the outer side of the capillary of the hydraulic tube 56 is fixedly connected to a lower pressure plate 58. A limit strip is fixedly connected to the outer surface of the capillary of the hydraulic tube 56. A limit sleeve 59 symmetrical to the limit strip of the hydraulic tube 56 is fixedly connected to the side of the lower pressure plate 58 close to the hydraulic tube 56. The limit sleeve 59 slides on the outer surface of the capillary of the hydraulic tube 56. The limit sleeve 59 is used to stabilize the movement of the lower pressure plate 58 to prevent the lower pressure plate 58 from tilting and rotating.

[0022] like Figure 2 Figure 8 and Fig. 9As shown, the lower pressure plate 58 is provided with a water injection assembly for watering the roots of the seedlings, and the water injection assembly includes a fixed tube 61 fixedly connected to the bottom of the lower pressure plate 58, and the fixed tube 61 is internally slidably connected to the plug 62, and the end of the plug 62 away from the fixed tube 61 is set to an inclined surface for easy insertion into the soil, and the end of the plug 62 close to the fixed tube 61 is fixedly connected to a hollow bracket, and the hollow bracket of the plug 62 is fixedly connected to a piston rod 63 at one end close to the inside of the fixed tube 61. The piston rod 63 is composed of a disc plug 2 and a straight rod 2. A gap is left between the disc plug of the piston rod 63 and the inner wall of the fixed tube 61, so that water can be effectively discharged downward, and the inside of the fixed tube 61 is fixedly connected to a sealing plate 64, and a drainage hole is opened on the sealing plate 64. The disc plug 2 of the piston rod 63 can completely cover the drainage hole of the sealing plate 64, which is used to irrigate the sealing plate 64. 4 is effectively blocked, the straight rod 2 of the piston rod 2 63 slides in the middle of the sealing plate 64, a spring 3 65 is fixedly connected between the sealing plate 64 and the insert pipe 62, and a connecting pipe 66 is fixedly connected to the top of the lower pressure plate 58.

After opening the cover plate, it is convenient to pour water into the box body. The two ends of the connecting pipe 66 are respectively connected to the fixed pipe 1 61 and the water tank 67. The bottom end of the insert pipe 62 is slidably connected with an annular spray head 68. The outer surface of the sliding connection between the annular spray head 68 and the insert pipe 62 is frosted, so that the annular spray head 68 and the insert pipe 62 are in a tight sliding state, which is used to prevent the annular spray head 68 from sliding arbitrarily on the insert pipe 62 after pulling it.

[0023] like Figure 8 and Fig.10 As shown, a fertilization assembly for fertilization is provided on the hydraulic pipe 56, and the fertilization assembly includes a fixed plate 71 fixedly connected to the capillary of the hydraulic pipe 56, and a feeding hopper 72 is fixedly connected to the upper surface of the fixed plate 71 away from one end of the hydraulic pipe 56, and the top of the feeding hopper 72 is set in a square funnel shape, which is used to facilitate the feeding of fertilizers or herbicides into the feeding hopper 72, and a fixed pipe 2 73 corresponding to the position of the feeding hopper 72 is fixedly connected to the lower surface of the fixed plate 71, and the fixed pipe 2 73 is connected to the feeding hopper 72. The end of the lower pressure plate 58 away from the limiting sleeve 59 is fixedly connected. A movable tube 75 is fixedly connected, and the movable tube 75 slides inside the fixed tube 2 73. The top of the movable tube 75 is arranged to be a hollow cone. The bottom of the movable tube 75 passes through the lower pressure plate 58 and extends to its bottom. A nozzle with dense holes is arranged at the bottom end of the movable tube 75 for spraying fertilizers or herbicides. A sealing ring 74 is fixedly connected to the top of the inner wall of the fixed tube 2 73. The bottom of the sealing ring 74 fits with the cone at the top of the movable tube 75. After the movable tube 75 fits with the bottom of the sealing ring 74, the hollow part of the movable tube 75 can be blocked to form a seal.

[0024] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: The roller 35 does not touch the ground. At this time, the movable plate 33 is in the lowest position, the spring 1 32 is not compressed by the movable plate 33, the top of the slide rod 54 touches the depression of the corrugated outer edge of the pushing plate 48, the spring 2 52 is not compressed by the slide block 53, the piston plate 55 is at the end of the thick tube of the hydraulic tube 56 away from the thin tube, and then the disc plug 1 of the piston rod 1 57 is in the highest position of the thin tube of the hydraulic tube 56, the straight rod 1 of the piston rod 1 57 makes the lower pressure plate 58 fit with the bottom of the thin tube of the hydraulic tube 56, the lower pressure plate 58 prevents the corrugated tube of the connecting tube 66 from being pulled and stretched, the insert pipe 62 is not inserted into the root soil of the seedling, and then the insert pipe 62 is in the lowest position of the fixed tube 1 61, and the insert pipe 62 makes the disc plug 2 of the piston rod 2 63 fit with the top of the sealing plate 64 to form a seal. At this time, the spring three 65 is not compressed by the insert tube 62, and the lower pressure plate 58 makes the top of the movable tube 75 and the sealing ring 74 fit together to form a seal.

[0025] Preparation: The staff moves the cart 1 to the ridge of the agricultural product breeding site by pushing it. At the same time, the staff can pull the annular spray head 68 to make the annular spray head 68 slide in the insert pipe 62, so that the annular spray head 68 is close to the root of the seedlings, and water can be effectively sprayed to the root of the seedlings in the future. At this time, because the cart 1 has been in contact with the ground, the roller 35 is also in contact with the ground. The roller 35 is resisted by the ground and moves upward. The roller 35 drives the rotating shaft 1 34 to move upward synchronously. During the upward movement of the rotating shaft 1 34, the movable plate 33 is driven to move upward between the two limit partitions 31 and compress the spring 1 32. In addition, the rotating shaft 1 34 The eight right-angle rods 38 will also be driven through the transmission holes 37 to slide upward in the transmission holes 37 on the corresponding two rotating shafts 36. The transmission will not be affected by the slidable setting. Then the cover of the water tank 67 will be opened, and the water required for irrigation will be injected into the water tank 67. Then the cover of the water tank 67 will be closed. The water injected into the water tank 67 will flow downward along the connecting pipe 66 to the top of the piston rod 63 disc plug 2. In addition, the fertilizer required to be injected is injected into the feeding hopper 72, where the fertilizer is mainly liquid for easy spraying. The fertilizer injected into the feeding hopper 72 will flow downward along the fixed pipe 2 73 to the top of the movable pipe 75.

[0026] Driver of drive components: When the staff pushes the cart 1 to travel in the ditch, the roller 35 contacts the ground, and the roller 35 rolls on the ground during the travel of the cart 1. The roller 35 drives the rotating shaft 1 34 to rotate at the bottom of the vertical rod of the movable plate 33 during the rolling process. The rotating shaft 1 34 transmits the transmission through the transmission hole 37 to the right-angle rod 38. The transmission of the right-angle rod 38 transmits the transmission hole 37 of the rotating shaft 2 36 to make the rotating shaft 2 36 rotate synchronously. The rotation of the rotating shaft 2 36 drives the cam plate 42 to rotate synchronously in the transmission cavity 41. Therefore, the driving can be formed by the rolling of the roller 35.

[0027] In addition, if the ridges and ditches of the breeding ground are uneven, the elastic reset action of the spring 1 32 allows the movable plate 33 to always contact the ground through the rotating shaft 1 34, thereby ensuring that the roller 35 can effectively roll on the ground, thereby adapting to ridges and ditches of different heights or unevenness, thereby improving the adaptability of the drive of the device.

[0028] The intermittent component uses the extension component to cooperate with the water injection component for intermittent watering: During the rotation of the cam plate 42 mentioned above, the cam plate 42 will drive the toggle rod 43 and the positioning arc block 44 to rotate synchronously, wherein the toggle rod 43 slides into the toggle groove of the intermittent wheel 47 during the rotation, and the toggle rod 43 will drive the intermittent wheel 47 to rotate through the toggle groove, and when the positioning arc block 44 rotates to fit with the arc groove of the intermittent wheel 47, the positioning arc block 44 can keep the intermittent wheel 47 stationary through the arc groove, because the toggle groove and the arc groove on the intermittent wheel 47 are alternately distributed, and the toggle rod 43 can intermittently enter the toggle groove and drive the intermittent wheel 47 to rotate a small amplitude. At this time, the positioning arc block 44 will stabilize the intermittent wheel 47 through the arc groove, and so on, and the intermittent wheel 47 will also drive the pushing plate 48 to rotate intermittently through the fixed shaft 46.

[0029] During the intermittent rotation of the pushing plate 48, the corrugated convex part of the pushing plate 48 pushes the slide bar 54, causing the slide bar 54 to move toward the side close to the hydraulic pipe 56. The slide bar 54 drives the slider 53 to move synchronously and compress the spring 2 52. In addition, the slide bar 54 also drives the piston plate 55 to move to the left inside the hydraulic pipe 56. Figure 7On the left side, the movement of the piston plate 55 will push the hydraulic oil in the thick tube of the hydraulic pipe 56 to flow into the thin tube, and the hydraulic oil will push the piston rod 1 57 to move obliquely downward in the thin tube of the hydraulic pipe 56. The piston rod 1 57 drives the lower pressure plate 58 to move obliquely downward, and the lower pressure plate 58 drives the outer surface of the limit sleeve 59 to move obliquely downward synchronously. The downward movement of the lower pressure plate 58 will pull the bellows of the connecting pipe 66 to stretch. In addition, the lower pressure plate 58 will also drive the fixed pipe 1 61 to move obliquely downward synchronously. The fixed pipe 1 61 The insert pipe 62 moves downward obliquely. At this time, because the middle insert pipe 62 is between the two seedlings, and because the cart 1 is in a moving state, when the insert pipe 62 moves synchronously to the position corresponding to the seedlings, the insert pipe 62 also moves downward obliquely. In the process of the insert pipe 62 moving obliquely downward, the annular spray head 68 will be driven to hit the soil at the root of the seedlings. After the annular spray head 68 hits the soil and cannot move downward, the piston rod 2 63 cannot move downward and remains stationary. When the piston rod 61 continues to move downward, the fixed pipe 1 61 will drive the sealing plate 64 to move downward synchronously and compress the spring 3 65 between the insert pipe 62. Due to the downward movement of the sealing plate 64, the disc plug 2 of the piston rod 2 63 cannot conflict with the sealing plate 64 at this time, and then the piston rod 2 63 no longer seals the drainage hole of the sealing plate 64. The water will flow downward through the gap between the disc plug 2 of the piston rod 2 63 and the fixed pipe 1 61, and then flow downward through the drainage hole of the sealing plate 64, and finally be discharged downward into the annular sprinkler head 68 through the insert pipe 62. The water is sprayed around the roots of the seedlings through the annular sprinkler head 68, and the annular sprinkler head 68 can irrigate the surrounding areas of the roots of the seedlings, which can ensure the accuracy of watering. Compared with the traditional sprinkler irrigation method, it can avoid watering on the leaves of the seedlings and other soils, which are prone to large water evaporation losses under the action of sunlight and air. In addition, directly irrigating the roots of the seedlings can avoid a large amount of water loss in the process of reaching the roots of the seedlings.

[0030] Because the corrugated protrusions of the pushing plate 48 correspond to the toggle grooves of the intermittent wheel 47, and the corrugated depressions of the pushing plate 48 correspond to the arc grooves of the intermittent wheel 47, and in the process of the toggle rod 43 driving the intermittent wheel 47 to rotate through the toggle grooves of the intermittent wheel 47, the pushing plate 48 will push the slide bar 54, and the positioning arc block 44 will not push the slide bar 54 during the non-rotation of the intermittent wheel 47 through the arc grooves of the intermittent wheel 47. Referring to the above working process, that is, during the rotation of the intermittent wheel 47, the annular sprinkler head 68 will water, and the non-rotation of the intermittent wheel 47 will stop the annular sprinkler head 68 from watering, and intermittent watering can be achieved by reciprocating. The watering work can be carried out by intermittently driving the water injection component to avoid the waste of water resources caused by continuous watering, and also avoid the situation where the seedlings are over-watered and cause root rot of the seedlings. In addition, the consistency of the watering amount for each seedling can be ensured, which ensures the consistency of the watering amount for each seedling.

[0031] In addition, because the volume of the thick tube of the hydraulic tube 56 is larger than that of the thin tube of the hydraulic tube 56, the piston plate 55 can move a short distance to make the piston rod 57 move downward a long distance, so that the distance that the piston rod 57 drives the lower pressure plate 58 to move is extended. By extending the movement distance of the lower pressure plate 58, the insert pipe 62 can be effectively inserted into the root of the seedling, ensuring that water can be effectively irrigated at the root of the seedling, avoiding the problem of the annular sprinkler head 68 not contacting the soil at the root of the seedling, resulting in the inability to irrigate normally, thereby improving the effectiveness of irrigation.

[0032] The above-mentioned watering work can be achieved by driving watering without power supply through the driving component. Since the seedling cultivation area is large, it is not convenient to pull wires for power supply. By driving without power supply, the irrigation device can adapt to long-term and large-scale seedling cultivation site watering, avoiding the use of batteries to power the water, so that there will be insufficient power during the long-term watering and fertilizing process, and further avoiding the need to add batteries to cause the cart 1 to be too heavy and inconvenient to carry.

[0033] The fertilization component fertilizes the roots of the seedlings: During the movement of the lower pressure plate 58, the movable tube 75 will be driven to move obliquely downward inside the fixed tube 73. After the movable tube 75 moves downward, the hollow cone at the top of the movable tube 75 no longer conflicts with the sealing ring 74, and the fertilizer will flow downward from the hollow cone at the top of the movable tube 75. After continuing to flow downward through the movable tube 75, it will be sprayed from the nozzle at the bottom of the movable tube 75 to the roots of the seedlings, thereby fertilizing the roots of the seedlings. Fertilizing the roots of the seedlings can allow the roots of the seedlings to absorb nutrients in the fertilizer more quickly, and the roots of the seedlings can absorb and utilize nutrients more efficiently, reducing fertilizer waste.

[0034] The fertilization component removes weeds around the roots of the seedlings: In the above, fertilizer is fed into the feeding hopper 72, and herbicide can also be fed into the feeding hopper 72. During the operation of the above structure, the herbicide can be sprayed around the roots of the seedlings through the nozzle at the bottom of the movable tube 75, which can effectively kill the weeds around the seedlings. Compared with large-area spray weeding, this method is more targeted. For some special environments that are difficult to weed mechanically or manually, such as in some flower seedling bases with complex terrain, the herbicide is placed in a small area around the roots, which can effectively control the growth of weeds and ensure the quality of the seedlings without destroying the seedlings.

[0035] It should be noted that before adding fertilizers or herbicides, the inside of the feeding hopper 72, the second fixed pipe 73 and the movable pipe 75 need to be cleaned to ensure that there are no residues of the previously added fertilizers and herbicides inside.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
