Description

Technical Field

[0001] The invention relates to the technical field of irrigation depth detection, in particular to an irrigation depth detection device for gardening. Background Art

[0002] The impact of garden irrigation on garden landscape is mainly reflected in maintaining plant vitality, promoting flower blooming, and maintaining lawn greenness. Reasonable irrigation helps to show the better landscape effect of the garden. At the same time, irrigation can also regulate the microclimate of the garden and provide a more comfortable environment for tourists.

[0003] Proper irrigation can ensure that plants get enough water and promote their normal growth and development. Watering the soil properly after the soil surface is slightly dry can keep the soil moist but not too wet, thus preventing the roots from being unable to breathe and affecting nutrient absorption.

[0004] Excessive irrigation or insufficient irrigation will affect the normal growth of plants. Therefore, it is necessary to detect the irrigation depth during irrigation. The conventional detection method is to use a humidity sensor probe to penetrate deep into the irrigated soil for detection.

[0005] Because the detection is carried out after irrigation, that is, the probe of the humidity sensor goes deeper into the bottom soil after irrigation. In the process of the humidity sensor probe going deeper, it will come into contact with soil at different depths. The water content of soil at different depths is different. Some wet soil is very likely to adhere to the probe in this process. As a result, after the probe reaches the predetermined depth, the soil around it may be the soil brought down from the upper layer. The humidity of this part of the soil is higher, resulting in inaccurate detection results.

[0006] For example, a Chinese patent discloses an irrigation depth detection device for landscaping (application number 202320808843.9). In this patent, sampling can be performed by passing the detection tube through the bottom plate and inserting it into the garden soil. The mounting plate can be inserted into the through groove from the lower end through the bar slider and the bar slide groove, and the mounting plate can be fixed by inserting the elastic card block into the card groove. The rotation of the turntable controlled by the handle can drive the threaded rod to rotate, and the threaded rod can be lifted and lowered in the vertical direction, thereby driving the detection tube to move downward and insert into the soil. When the detection tube moves upward, the soil sample in the garden can be brought out. After taking out the detection tube and removing the mounting plate, the staff can perform irrigation depth detection on the soil sample through the through groove.

[0007] During the detection process, it is inevitable that some upper wet soil will be especially high in humidity and sticky and adhere to the surface, resulting in the presence of some upper wet soil in the final detection, which cannot truly and accurately reflect the soil moisture at the predetermined depth.

DETAILED DESCRIPTION

[0032] 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.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0034] See also Figure 1 to Figure 10 In an embodiment of the present invention, a garden irrigation depth detection device includes: A detection box 1, and a screw rod 4 rotatably installed in the detection box 1, and a guide column 6 is fixedly installed in the detection box 1; Also includes: See also Figure 1-Figure 5 , Figure 7 , Figure 8, a drilling mechanism is arranged on the detection box 1, a drill bit 20 is connected to the drilling group mechanism, the drilling mechanism includes a motor 15 fixedly mounted on the top of the detection box 1, a transmission rod 16 connected to the output shaft of the motor 15 is rotatably mounted in the detection box 1, the transmission rod 16 is hollow, a card slot 17 is opened on the circumferential outer wall of the transmission rod 16, a driven component is arranged in the transmission rod 16, wherein the driven component includes a rotating rod 19 slidably mounted in the transmission rod 16 and passing through the detection box 1, the rotating rod 19 is fixedly connected to the drill bit 20, the rotating rod 19 is hollow, and a movable ring 18 slidably connected to the card slot 17 is fixed on the rotating rod 19.

[0035] In detail, in order to ensure that the landscaping is done properly, the plants need to be irrigated frequently to ensure that the plants get enough water. However, if the irrigation volume is insufficient and the plants do not get enough water, it will affect their normal growth and development. The physiological activities in the plant body must be carried out normally with the participation of water. Insufficient water will accelerate the aging of the plant, causing the plant to wilt, and even cause the plant to die in severe cases. If the irrigation volume is too much and there is too much water, the groundwater level will rise, causing land salinization. The soil may also be soaked in water for a long time, resulting in obstructed root breathing, easy root rot and death, which in turn affects the healthy growth of the plant. Therefore, it is necessary to detect the irrigation depth during irrigation.

[0036] Preferably, when it is necessary to detect the irrigation depth, it is necessary to control the drill bit 20 to drill into the soil. At this time, the motor 15 works and drives the transmission rod 16 to rotate, thereby driving the slot 17 to move. Under the action of the slot 17 and the movable ring 18, the rotating rod 19 is driven to rotate synchronously, thereby driving the drill bit 20 to rotate. At the same time, under the action of the lifting mechanism, the movable ring 18 is driven to move along the length direction of the slot 17 to drive the rotating rod 19 to move toward the ground. The rotating rod 19 also drives the drill bit 20 to move, so that the drill bit 20 drills toward the ground while rotating. When the drill bit 20 drills to the required depth, the motor 15 stops rotating. At this time, the humidity of the soil at this depth can be detected to detect the irrigation depth of the soil. See also Figure 1-Figure 5 , Figure 8 , Fig.10The detection box 1 is provided with a lifting mechanism connected with the drilling mechanism and the guide column 6, the drilling mechanism can drive the drill bit 20 to rotate, and the lifting mechanism can drive the drill bit 20 to move along the length direction of the guide column 6 through the drilling mechanism, the lifting mechanism includes a cylinder 2 fixedly installed on the top of the detection box 1 and symmetrically arranged, a support plate 3 is fixed on the output end of the cylinder 2, a rotating ring 22 slidably connected with the slot 17 is sleeved on the transmission rod 16, the rotating ring 22 abuts against the support plate 3, and a guide assembly connected with the movable ring 18 is provided on the support plate 3, wherein the guide assembly includes a fixed installation A first movable sleeve 5 and a second movable sleeve 7 are mounted on the support plate 3 and are symmetrically arranged. The first movable sleeve 5 is slidably connected to the screw rod 4, and the second movable sleeve 7 is slidably connected to the guide column 6. A limiting structure connected to the movable ring 18 is provided on the support plate 3. The above-mentioned limiting structure includes a fixed rod 13 fixedly mounted on the support plate 3 and symmetrically arranged. A support ring 14 is fixed at one end of the fixed rod 13 away from the support plate 3, and the support ring 14 is in abutment with the movable ring 18. A spring 23 is sleeved on the transmission rod 16, and the two ends of the spring 23 are respectively in abutment with the movable ring 18 and the rotating ring 22.

[0037] It should be noted that, in the initial state, the spring 23 is in a compressed state, so that the spring 23 provides supporting force to the movable ring 18 and the rotating ring 22 respectively, so that the distance between the movable ring 18 and the rotating ring 22 is maximized. At this time, the rotating ring 22 abuts against the support plate 3, and the movable ring 18 abuts against the support ring 14. Under the action of the support ring 14, it is ensured that the movable ring 18 no longer moves. When it is necessary to detect the soil irrigation depth, at this time, the cylinder 2 works and drives the support plate 3 to move toward the bottom of the detection box 1. The support plate 3 will also drive the first movable sleeve 5 and the second movable sleeve 7 to move along the length direction of the screw rod 4 and the guide column 6 respectively. The second movable sleeve 7 and the guide column 6 have a guiding function to ensure that the support plate 3 No deviation will occur during movement, and the support plate 3 will also drive the fixed rod 13 to move, so that the support ring 14 moves synchronously. At the same time, the support plate 3 will also push the rotating ring 22 to move along the length direction of the slot 17, so as to control the movable ring 18 through the spring 23 to always keep it in contact with the support ring 14. At this time, the elastic potential energy of the spring 23 remains unchanged. When the movable ring 18 moves to the position cooperating with the depth control mechanism, the movable ring 18 no longer moves. At this time, the drill bit 20 reaches the required depth, and the support plate 3 continues to move, so that the support ring 14 is separated from the movable ring 18, and the conduction detection mechanism is driven to move through the rotating ring 22 to detect the soil moisture at this depth. At the same time, the rotating ring 22 will also compress the spring 23.

[0038] Preferably, when the detection is completed, the support plate 3 can be controlled by the cylinder 2 to move toward the initial position. At this time, the spring 23 is elastically released, so that the position of the movable ring 18 remains unchanged until the support ring 14 moves to the position abutting against the movable ring 18 again, driving the movable ring 18 to move, thereby driving the drill bit 20 to move in the direction of leaving the soil through the rotating rod 19 until the support plate 3 is reset and the drill bit 20 is separated from the soil. At this time, the drilled hole can be filled with soil. Among them, since the soil is in a loose state when it is irrigated, the drill bit 20 can be easily drilled into the soil under the support force of the spring 23, thereby ensuring that the detection is carried out smoothly. If the resistance of the soil to the drill bit 20 is greater than the support force of the spring 23, the spring 23 will be compressed, so that the support force of the drill bit 20 will gradually increase, thereby avoiding the problem of damage to the drill bit 20 during the drilling process due to excessive support force provided to the drill bit 20 in the initial state.

[0039] See also Figure 2-Figure 5 , Figure 7 , Figure 8 , a depth control mechanism is arranged on the guide column 6 and is connected to the screw rod 4 and the drilling mechanism. The depth control mechanism can limit the drilling depth of the drill bit 20 through the drilling mechanism. The depth control mechanism includes a threaded sleeve 8 movably mounted on the screw rod 4 and threadedly matched with the screw rod 4. A guide sleeve 10 is slidably mounted on the guide column 6. A connecting plate 9 fixedly connected to the threaded sleeve 8 is fixed on the side wall of the guide sleeve 10. A support assembly is arranged on the connecting plate 9, wherein the support assembly includes a fixed sleeve 11 fixedly mounted on the connecting plate 9, a limiting ring 12 is fixed at the end of the fixed sleeve 11, and the limiting ring 12 is in contact with the movable ring 18.

[0040] Furthermore, since the irrigation amount required for each plant is different, the required drilling depth of the drill bit 20 is also different. The non-threaded part of the screw rod 4 is slidably connected with the first movable sleeve 5, and the threaded part of the screw rod 4 cooperates with the threaded sleeve 8. In the initial state, the threaded sleeve 8 is located at the end of the stroke of the screw rod 4 toward the ground, so that the distance between the connecting plate 9 and the cylinder 2 is the largest, so that the initial distance between the limit ring 12 and the movable ring 18 is the farthest. When it is necessary to detect the irrigation depth, under the action of the cylinder 2, the support plate 3 is pushed to move, so that the movable ring 18 is controlled to move synchronously through the spring 23, so as to control the drill bit 20 to drill toward the inside of the ground through the rotating rod 19. When the movable ring 18 moves to the position abutting against the limit ring 12, since the screw rod 4 has a self-locking effect, the limit ring 12 will not move, and the height of the movable ring 18 will no longer change. The drill bit 20 drills to the required depth. At this time, the support plate 3 continues to move and drives the conduction detection mechanism to move through the rotating ring 22 to detect the moisture of the soil at this depth, thereby confirming the irrigation depth.

[0041] Preferably, if the amount of irrigation required for the plant decreases, the drilling depth of the drill bit 20 needs to be reduced. At this time, the screw rod 4 can be controlled to rotate by an external driving source, thereby driving the threaded sleeve 8 to move. The threaded sleeve 8 will also drive the guide sleeve 10 to move along the length direction of the guide column 6 through the connecting plate 9. The guide column 6 and the guide sleeve 10 have a guiding function to ensure that the threaded sleeve 8 moves along the length direction of the screw rod 4 and will not rotate with the screw rod 4. The connecting plate 9 will also drive the limit ring 12 to move through the fixed sleeve 11, so that the distance between the limit ring 12 and the movable ring 18 is reduced until the limit ring 12 reaches the required height. At this time, when the irrigation depth is detected again, the distance that the movable ring 18 can move changes, thereby changing the drilling depth of the drill bit 20 to detect the irrigation depth.

[0042] See also Figure 2-Figure 9 , a conduction detection mechanism is arranged on the drilling mechanism and connected to the lifting mechanism, a detection probe 25 is connected to the conduction detection mechanism, the conduction detection mechanism can be actuated when the lifting mechanism moves, and when the drill bit 20 stops moving, the detection probe 25 is controlled to move to a desired detection position, the conduction detection mechanism includes a follower rod 24 fixedly mounted on the rotating ring 22, the follower rod 24 is fixedly connected to the detection probe 25, and a vertical groove 2401 and a spiral groove are opened on the circumferential outer wall of the follower rod 24 2402, a guide assembly connected to the follower rod 24 is provided in the rotating rod 19, wherein the guide assembly includes a rotating sleeve 26 rotatably installed in the rotating rod 19 and slidably connected to the follower rod 24, a limit block 28 slidably engaged with the vertical groove 2401 and the spiral groove 2402 is fixed to the inner wall of the rotating sleeve 26, a second conducting hole 27 is opened on the circumferential outer wall of the rotating sleeve 26, and a first conducting hole 21 cooperating with the second conducting hole 27 is opened on the circumferential outer wall of the rotating rod 19.

[0043] To go further, in the initial state, under the action of the spring 23, the movable ring 18 is in contact with the support ring 14, and the distance between the movable ring 18 and the rotating ring 22 is the largest. Therefore, the distance between the detection probe 25 and the drill bit 20 is the largest. At this time, the limit block 28 is located at the end of the stroke of the vertical groove 2401 away from the spiral groove 2402. The first conducting hole 21 and the second conducting hole 27 are in a separated state, so that the rotating rod 19 is in a blocked state, and the detection probe 25 cannot detect the moisture in the soil. When it is necessary to detect the irrigation depth, under the action of the cylinder 2, the rotating ring 22 and the movable ring 18 are pushed to move synchronously, thereby driving the rotating rod 19 and the follower rod 24 to move synchronously. At this time, the position of the limit block 28 in the vertical groove 2401 will not change. When the movable ring 18 moves to the position abutting against the limit ring 12, the position of the movable ring 18 is no longer The rotation of the rotating ring 22 is changed, therefore, the positions of the rotating rod 19 and the rotating sleeve 26 are no longer changed, and the drill bit 20 drills to the required depth. At this time, the motor 15 stops working, the support plate 3 continues to move, and pushes the rotating ring 22 to move toward the movable ring 18 to compress the spring 23. The rotating ring 22 also drives the follower rod 24 to move, so that the limit block 28 slides in the vertical groove 2401. When the limit block 28 disengages from the vertical groove 2401 and enters the spiral groove 2402, the rotating sleeve 26 rotates a certain angle, thereby driving the second conducting hole 27 to move. When the limit block 28 moves to the end of the stroke of the spiral groove 2402 away from the side of the vertical groove 2401, the second conducting hole 27 is connected to the first conducting hole 21. The detection probe 25 also moves to the same horizontal plane as the first conducting hole 21. At this time, the detection probe 25 can detect the soil moisture to confirm the irrigation depth.

[0044] The specific working principle of the present invention is as follows: In the process of using the irrigation depth detection device for landscaping, when it is necessary to detect the irrigation depth, it is necessary to control the drill bit 20 to drill into the soil. At this time, the motor 15 works and drives the transmission rod 16 to rotate, thereby driving the slot 17 to move. Under the action of the slot 17 and the movable ring 18, the rotating rod 19 is driven to rotate synchronously, thereby driving the drill bit 20 to rotate. At the same time, under the action of the lifting mechanism, the movable ring 18 is driven to move along the length direction of the slot 17 to drive the rotating rod 19 to move toward the ground. The rotating rod 19 will also drive the drill bit 20 to move, so that the drill bit 20 drills toward the ground while rotating. When the drill bit 20 drills to the required depth, the motor 15 stops rotating. At this time, the humidity of the soil at this depth can be detected to detect the irrigation depth of the soil. In the initial state, the spring 23 is in a compressed state, so that the spring 23 provides supporting force to the movable ring 18 and the rotating ring 22 respectively, so that the distance between the movable ring 18 and the rotating ring 22 is maximized. At this time, the rotating ring 22 abuts against the support plate 3, and the movable ring 18 abuts against the support ring 14. Under the action of the support ring 14, it is ensured that the movable ring 18 no longer moves. When it is necessary to detect the soil irrigation depth, at this time, the cylinder 2 works and drives the support plate 3 to move toward the bottom of the detection box 1. The support plate 3 will also drive the first movable sleeve 5 and the second movable sleeve 7 to move along the length direction of the screw rod 4 and the guide column 6 respectively. The second movable sleeve 7 and the guide column 6 have a guiding function to ensure that the support plate 3 moves. No deviation will occur, and the support plate 3 will also drive the fixed rod 13 to move, so that the support ring 14 moves synchronously. At the same time, the support plate 3 will also push the rotating ring 22 to move along the length direction of the slot 17, so as to control the movable ring 18 through the spring 23 to always keep it in contact with the support ring 14. At this time, the elastic potential energy of the spring 23 remains unchanged. When the movable ring 18 moves to the position cooperating with the depth control mechanism, the movable ring 18 no longer moves. At this time, the drill bit 20 reaches the required depth, and the support plate 3 continues to move, so that the support ring 14 is separated from the movable ring 18, and the conduction detection mechanism is driven to move through the rotating ring 22 to detect the soil moisture at this depth. At the same time, the rotating ring 22 will also compress the spring 23.

[0045] When the detection is completed, the support plate 3 can be controlled by the cylinder 2 to move toward the initial position. At this time, the spring 23 is elastically released, so that the position of the movable ring 18 remains unchanged until the support ring 14 moves to the position abutting against the movable ring 18 again, driving the movable ring 18 to move, thereby driving the drill bit 20 to move in the direction of leaving the soil through the rotating rod 19 until the support plate 3 is reset and the drill bit 20 is separated from the soil. At this time, the drilled hole can be filled with soil. Among them, since the soil is in a loose state when it is irrigated, the drill bit 20 can be easily drilled into the soil under the support force of the spring 23, thereby ensuring the smooth progress of the detection. If the resistance of the soil to the drill bit 20 is greater than the support force of the spring 23, the spring 23 will be compressed, so that the support force of the drill bit 20 will gradually increase, thereby avoiding the problem of damage to the drill bit 20 during the drilling process due to excessive support force provided to the drill bit 20 in the initial state.

[0046] Since the irrigation amount required for each plant is different, the required drilling depth of the drill bit 20 is also different. The non-threaded part of the screw rod 4 is slidably connected with the first movable sleeve 5, and the threaded part of the screw rod 4 cooperates with the threaded sleeve 8. In the initial state, the threaded sleeve 8 is located at the end of the stroke of the screw rod 4 toward the ground, so that the distance between the connecting plate 9 and the cylinder 2 is the largest, so that the initial distance between the limit ring 12 and the movable ring 18 is the farthest. When it is necessary to detect the irrigation depth, under the action of the cylinder 2, the support plate 3 is pushed to move, so that the movable ring 18 is controlled to move synchronously through the spring 23, so as to control the drill bit 20 to drill toward the inside of the ground through the rotating rod 19. When the movable ring 18 moves to the position abutting against the limit ring 12, since the screw rod 4 has a self-locking effect, the limit ring 12 will not move, and the height of the movable ring 18 will no longer change. The drill bit 20 drills to the required depth. At this time, the support plate 3 continues to move and drives the conduction detection mechanism to move through the rotating ring 22 to detect the moisture of the soil at this depth, thereby confirming the irrigation depth.

[0047] If the amount of irrigation required for the plant decreases, the drilling depth of the drill bit 20 needs to be reduced. At this time, the screw rod 4 can be controlled to rotate by an external driving source, thereby driving the threaded sleeve 8 to move. The threaded sleeve 8 will also drive the guide sleeve 10 to move along the length direction of the guide column 6 through the connecting plate 9. The guide column 6 and the guide sleeve 10 have a guiding function to ensure that the threaded sleeve 8 moves along the length direction of the screw rod 4 and will not rotate with the screw rod 4. The connecting plate 9 will also drive the limit ring 12 to move through the fixed sleeve 11, so that the distance between the limit ring 12 and the movable ring 18 is reduced until the limit ring 12 reaches the required height. At this time, when the irrigation depth is detected again, the distance that the movable ring 18 can move changes, thereby changing the drilling depth of the drill bit 20 to detect the irrigation depth.

[0048] When the spring 23 returns to the initial state, the movable ring 18 abuts against the support ring 14, and the distance between the movable ring 18 and the rotating ring 22 is maximized. Therefore, the distance between the detection probe 25 and the drill bit 20 is maximized. At this time, the limit block 28 is located at the end of the stroke of the vertical groove 2401 away from the spiral groove 2402. The first conducting hole 21 and the second conducting hole 27 are in a separated state, so that the rotating rod 19 is in a blocked state, and the detection probe 25 cannot detect the moisture in the soil. When it is necessary to detect the irrigation depth, the rotating ring 22 and the movable ring 18 are pushed to move synchronously under the action of the cylinder 2, thereby driving the rotating rod 19 and the following The movable rod 24 moves synchronously. At this time, the position of the limit block 28 in the vertical groove 2401 will not change. When the movable ring 18 moves to the abutment position with the limit ring 12, the position of the movable ring 18 will no longer change. Therefore, the positions of the rotating rod 19 and the rotating sleeve 26 will no longer change. The drill bit 20 drills to the required depth. At this time, the motor 15 stops working, the support plate 3 continues to move, and pushes the rotating ring 22 to move toward the movable ring 18 to compress the spring 23. The rotating ring 22 will also drive the follower rod 24 to move, so that the limit block 28 slides in the vertical groove 2401. When the limit block 28 disengages from the vertical groove 2401 and enters the spiral groove 2402.
