Description

Technical Field

[0001] The present invention belongs to the technical field of tree measurement, and specifically relates to a device for measuring the rooting depth of trees. Background Art

[0002] Seedling cultivation refers to the growth mode of seedlings that cannot withstand the external environment during the seedling stage and needs to be cultivated and planted. Seedlings are mostly cultivated in indoor cultivation boxes to ensure the survival rate of the seedlings in the initial stage. After the seedlings are cultivated and grown in the indoor cultivation box for a certain period, they can be transplanted outdoors for planting.

[0003] During transplantation, the seedlings together with the cultivation box need to be transported to the transplantation area first, and then the seedlings are taken out of the cultivation box. In order to prevent the tree pit from being dug too deep or too shallow, which may affect the later growth of the seedlings, it is necessary to measure the rooting depth of the seedlings during transplantation to facilitate determining the depth of the tree pit to be dug.

[0004] Currently, in the existing technology, the root length of the seedlings is mostly judged by the feeling of the staff, and then the depth of the tree pit is dug according to the root length of the seedlings judged by the staff. This method of measuring the root length of the seedlings lacks a reference benchmark and has visual differences, resulting in a large error in the measured root length of the seedlings. In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a device for measuring the rooting depth of trees that can overcome or at least partially solve the above problems.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is as follows:

Among them, by moving the two partitions to both sides of the observation cylinder respectively to open the bottom of the upper measurement cavity, the soil filled in the upper measurement cavity falls into the bottom of the observation cylinder. The measuring rod is pushed downward by the electric telescopic rod. When the end of the measuring rod is parallel to the root system of the seedling away from the rootstock, by checking the numerical value of the scale mark on the surface of the measurement cylinder corresponding to the top of the measuring rod, the rooting depth of the seedling can be measured.

[0008] Preferably, it further includes a liquid storage tank and a water pump fixedly connected to the side wall of the observation cylinder.

A drain pipe fixedly communicated with the lower measuring cavity is provided at the bottom of the observation cylinder. An electromagnetic valve is provided on the drain pipe.

[0012] In order to wash the soil adhered to the tree roots and expose the roots, further, it also includes multiple groups of water spray nozzles. The multiple groups of water spray nozzles are all arranged obliquely upward and are equidistantly and fixedly connected to the inner wall of the observation cylinder in a circle. A water conveyance cavity communicating with the water spray nozzles is provided on the observation cylinder. The sliding boxes are fixedly communicated with the lower measuring cavity through a pipe one, and the sliding boxes are fixedly communicated with the water conveyance cavity through a pipe two.

The two arc-shaped plates are detachably connected by fixing bolts. The inner side wall of the arc-shaped plate is connected with a fixing plate. The fixing plate is attached to the outer wall of the tree trunk. The measuring cylinder is fixedly connected to the outer wall of one of the arc-shaped plates.

[0015] In order to prevent the fixing plate from affecting the growth of the tree, further, a second spring is further included. One end of the second spring is fixedly connected to the inner side wall of the arc-shaped plate, and the other end is fixedly connected to the outer side wall of the fixing plate. A guide rod is fixedly connected to the fixing plate, and a limiting block is fixedly connected to one end of the guide rod passing through the arc-shaped plate.

[0016] In order to increase the sealing performance of the sliding box, furthermore, a sealing sleeve sleeved on the outer wall of the connecting shaft is further included. The sealing sleeve is fixedly connected to the inner wall of the sliding box. A sealing ring is arranged on the sealing sleeve, and the sealing ring is attached to the outer wall of the connecting shaft.

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0032] Embodiment 1: Refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a device for measuring the rooting depth of trees, including an observation cylinder 1, and further including: a partition 201 symmetrically and slidably connected in the observation cylinder 1. Among them, an upper measurement cavity 101 is provided above the partition 201 in the observation cylinder 1, and the partition 201 is used to close or open the bottom of the upper measurement cavity 101; a measuring cylinder 7, detachably connected to the tree trunk, and both the observation cylinder 1 and the measuring cylinder 7 are transparently arranged; a measuring rod 701, slidably connected in the measuring cylinder 7; a driving part, connected to the measuring cylinder 7 and used to drive the measuring rod 701 to move. Among them, by moving the two partitions 201 to both sides of the observation cylinder 1 respectively, the bottom of the upper measurement cavity 101 is opened, and the soil filled in the upper measurement cavity 101 falls into the bottom of the observation cylinder 1. The measuring rod 701 is pushed downward by the electric telescopic rod 702. When the end of the measuring rod 701 is parallel to the root system of the sapling away from the rootstock, by checking the numerical value of the scale mark corresponding to the top of the measuring rod 701 on the surface of the measuring cylinder 7, the rooting depth of the sapling can be measured.

[0033] It also includes a liquid storage tank 806 and a water pump 805 fixedly connected to the side wall of the observation tube 1. The input end of the water pump 805 is fixedly connected to the liquid storage tank 806, and the water pump 805 is fixedly connected to the inner cavity of the measuring tube 7 through the conduit 804; it also includes a plurality of groups of water spray holes 801, which are equidistantly arranged on the end of the measuring rod 701. The axis of the measuring rod 701 is provided with a hollow cavity 8 connected to the water spray hole 801, and a pressure relief pipe 802, one end of which is fixedly connected to the inner cavity of the measuring tube 7, and the other end is fixedly connected to the hollow cavity 8. A pressure relief valve 803 is provided on the pressure relief pipe 802.

[0034] The driving part includes an electric telescopic rod 702 , which is fixedly mounted on the outer wall of the measuring tube 7 , and the measuring rod 701 is fixedly connected to the output end of the electric telescopic rod 702 .

[0035] When in use, it is necessary to measure the initial root length of the seedling before raising the seedling, so that after the seedling has grown for a period of time, it is convenient to measure the rooting depth of the seedling within the period. First, adjust the measuring tube 7 so that the end of the measuring rod 701 is parallel to the root of the seedling, then fix the measuring tube 7 on the trunk of the seedling, and then put the seedling into the upper measuring chamber 101 (it should be noted that the observation tube 1 is provided with a straightening component), and clamp and straighten the seedling by the straightening component so that the root of the seedling is kept parallel to the top of the observation tube 1, and then start the electric telescopic rod 702, which pushes the measuring rod 701 downward. When the end of the measuring rod 701 is parallel to the root of the seedling away from the root, the electric telescopic rod 702 is turned off. At this time, the staff can measure the length of the root of the seedling in the initial state by checking the scale mark value on the surface of the measuring tube 7 corresponding to the top of the measuring rod 701;

[0036] Then pour soil into the upper measuring cavity 101 until the soil fills the upper measuring cavity 101 and covers the roots of the saplings. Then start the water pump 805, which draws water mixed with nutrient solution from the liquid storage tank 806 and transports it into the measuring cylinder 7 through the conduit 804 (it should be noted that when the measuring rod 701 moves out of the measuring cylinder 7, a liquid storage cavity is formed between the measuring rod 701 and the measuring cylinder 7). A one-way valve is provided on the conduit 804, and then the nutrient solution is filled into the liquid storage cavity to make the liquid storage cavity The pressure gradually increases. After the water mixed with the nutrient solution fills the liquid storage chamber, the pressure inside the liquid storage chamber is greater than the pressure relief value set by the pressure relief valve 803. At this time, the pressure relief valve 803 automatically opens to relieve the pressure, so that part of the nutrient solution that continues to enter the liquid storage chamber is transported into the water spray hole 801 through the pressure relief pipe 802 and the hollow cavity 8 in turn and sprayed out, thereby improving the fertility of the soil in the upper measuring chamber 101, and then promoting the growth of the seedlings. The nutrient solution stored in the liquid storage chamber is beneficial to the subsequent measurement of the rooting depth of the seedling roots.

[0037] Example 2: ReferenceFigure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 , a tree root depth measuring device, which is basically the same as Embodiment 1. Further, sliding boxes 2 are integrally formed on both outer walls of the observation cylinder 1. A partition plate 201 is slidably connected in the sliding box 2. A connecting shaft 203 is provided in the sliding box 2. The connecting shaft 203 is rotatably connected to the partition plate 201 through a rotating sleeve 204. One end of the connecting shaft 203 passing through the sliding box 2 is fixedly installed with a handle 205.

[0038] It further includes a tension spring 202 and a threaded portion 3. One end of the tension spring 202 is fixedly connected to the partition plate 201, and the other end is fixedly connected to the inner wall of the sliding box 2. The threaded portion 3 is provided on the outer wall of one end of the connecting shaft 203 close to the handle 205 and is threadedly connected to the sliding box 2.

[0039] A lower measurement cavity 102 is provided below the partition plate 201 in the observation cylinder 1. A drain pipe 103 fixedly communicated with the lower measurement cavity 102 is provided at the bottom of the observation cylinder 1. A solenoid valve 104 is provided on the drain pipe 103.

[0040] It further includes multiple groups of spray nozzles 402. The multiple groups of spray nozzles 402 are all arranged obliquely upward and are fixedly connected at equal intervals around the inner wall of the observation cylinder 1. A water delivery cavity communicated with the spray nozzles 402 is opened on the observation cylinder 1. The sliding box 2 is fixedly communicated with the lower measurement cavity 102 through a pipe 4, and the sliding box 2 is fixedly communicated with the water delivery cavity through a pipe 401.

[0041] The way for the partition plate 201 to close the bottom of the first measurement cavity 101:

[0042] The staff can push the connecting shaft 203 through the handle 205 to drive the partition plate 201 to move out of the sliding box 2 and stretch the tension spring 202. When the threaded portion on the connecting shaft 203 contacts the sliding box 2, the staff can drive the connecting shaft 203 to rotate through the handle 205. The connecting shaft 203 is screwed into the sliding box 2 through the threaded portion 3 until the ends of the two partition plates 201 are in contact, so as to close the bottom of the first measurement cavity 101. At the same time, through the threaded portion 3 threadedly connected to the sliding box 2, the partition plate 201 at the bottom of the closed first measurement cavity 101 can be limited and fixed. At the same time, during the process of the sliding box 2 moving out of the sliding box 2, water in the second measurement cavity 102 is sucked into the sliding box 2 through the pipe 4 for temporary storage.

[0043] After the saplings are cultivated in the upper measurement cavity 101 for a certain period, they need to be transplanted. When transplanting, it is necessary to first measure the rooting depth of the saplings in order to determine the depth of the pits to be dug during transplantation, preventing the pits from being dug too deep or too shallow, which may affect the later growth of the saplings.

[0044] The first method for measuring the rooting depth of saplings:

[0045] The staff drives the connecting shaft 203 to rotate through the handle 205, so that the connecting shaft 203 screws out of the sliding box 2. At the same time, the connecting shaft 203 drives the partition plate 201 to move into the sliding box 2. When the threaded part 3 on the connecting shaft 203 completely moves out of the sliding box 2, stop rotating the connecting shaft 203 and release the handle 205. Then, under the elastic retraction force of the stretched spring 202, the partition plate 201 is automatically pulled into the sliding box 2, thus opening the bottom of the upper measurement cavity 101 and connecting the upper measurement cavity 101 with the lower measurement cavity 102. At this time, part of the soil inside the upper measurement cavity 101 falls into the lower measurement cavity 102, and the water level inside the lower measurement cavity 102 gradually rises with the continuously falling soil. At the same time, during the process of the partition plate 201 moving into the sliding box 2, the partition plate 201 squeezes the water stored inside the sliding box 2 and sprays it out through the second pipeline 401 and the water spraying nozzle 402 in sequence through the water conveyance cavity. One-way valves are provided on both the first pipeline 4 and the second pipeline 401, so as to wash the soil remaining on the roots of the saplings;

[0046] It should be noted that in order to improve the effect of washing the soil remaining on the roots of the saplings, the water spraying holes 801 can also be inclined downwardly opened at the end of the measuring rod 701. A water injection port is opened on the liquid storage tank 806. Water is injected into the liquid storage tank 806 through the water injection port, and then the water inside the liquid storage tank 806 is sucked by the water pump 805 and conveyed into the measuring cylinder 7 through the conduit 804. A one-way valve is provided on the conduit 804, and then water is filled into the liquid storage cavity, increasing the internal pressure of the liquid storage cavity filled with the nutrient solution. The pressure is relieved through the pressure relief valve 803, so that the continuously entering water inside the liquid storage cavity is sequentially conveyed into the water spraying holes 801 through the pressure relief pipe 802 and the hollow cavity 8 and sprayed out obliquely downward, thus achieving the purpose of washing the soil remaining on the roots of the saplings again, and further improving the effect of washing and cleaning the soil remaining on the roots of the saplings, making the roots of the saplings exposed;

[0047] Then, start the electric telescopic rod 702. The electric telescopic rod 702 pushes the measuring rod 701 to move downward. When the end of the measuring rod 701 is parallel to the root system of the sapling, turn off the electric telescopic rod 702. Then, the staff can measure the total length of the root system of the sapling by checking the scale marking value on the surface of the measuring cylinder 7 corresponding to the top of the measuring rod 701. Then, by subtracting the initially measured root length from the measured total root length, the rooting depth of the sapling during cultivation can be measured. At the same time, when the measuring rod 701 moves out of the measuring cylinder 7, the nutrient solution stored in the liquid storage chamber of the measuring cylinder 7 will move downward in the measuring cylinder 7 along with the measuring rod 701, causing the liquid level to drop. Then, the staff can more intuitively view the measured root system value through the scale marking value on the surface of the measuring cylinder 7 corresponding to the liquid level.

[0048] The second method for measuring the rooting depth of saplings:

[0049] Based on Method 1, if the rising water level inside the lower measuring chamber 102 does not contact the root system of the sapling, water can be continuously injected into the lower measuring chamber 102 through an external water source to raise the water level. When the liquid level contacts the root system of the sapling, stop injecting water into the lower measuring chamber 102. Then, the staff can more intuitively view the measured water level height value by checking the scale marking value on the surface of the observation cylinder 1 corresponding to the liquid level. Subsequently, by subtracting the height of the water level from the preset fixed value of the observation cylinder 1, the total length of the root system of the sapling can be obtained. Then, by subtracting the initially measured root length from the obtained total length of the root system of the sapling, the rooting depth of the sapling during cultivation can be measured.

[0050] In summary, the present invention can measure the rooting depth of the sapling during cultivation more accurately by taking the average value of the two measured rooting depth values of the sapling root system. Furthermore, it is convenient for the staff to obtain the required depth of the dug hole according to the rooting depth of the sapling root system, preventing the dug hole from being too deep or too shallow and affecting the growth of the sapling after transplantation.

[0051] It should be noted that when the rising water level inside the observation cylinder 1 submerges the root system of the sapling, the solenoid valve 104 on the drain pipe 103 can be opened to allow the water inside the lower measuring chamber 102 to be discharged from the lower measuring chamber 102 through the drain pipe 103, thereby reducing the water level height inside the observation cylinder 1 until the water level inside the observation cylinder 1 is parallel to the root system of the sapling. Then, close the solenoid valve 104 to prevent the water level from being too high and submerging the root system of the sapling, affecting the measurement of the rooting depth of the sapling root system by Method 1 and Method 2;

[0052] It should be noted that a filter screen (not shown in the figure) is provided inside the water inlet end of the drain pipe 103, so that the soil particles falling into the lower measurement chamber 102 can be filtered and blocked by the filter screen, preventing the soil particles carried in the water from blocking the drain pipe 103 when draining to the outside.

[0053] Example 3: Refer to Figure 2 、 Figure 5 and Figure 9 A device for measuring the rooting depth of trees is basically the same as that in Example 1. Further, the collar includes two arc-shaped plates 6, and the two arc-shaped plates 6 are detachably connected by fixing bolts 601. An inner fixing plate 602 is connected to the inner side wall of the arc-shaped plate 6, and the fixing plate 602 is attached to the outer wall of the tree trunk. The measuring cylinder 7 is fixedly connected to the outer wall of one of the arc-shaped plates 6.

[0054] In the way that the two arc-shaped plates 6 are snap-connected to form a collar, first, the staff docks the two arc-shaped plates 6 together, and then uses the fixing bolts 601 to fixedly connect the two arc-shaped plates 6, so as to achieve the purpose of snap-connecting the two arc-shaped plates 6 to form a collar, and sleeving the formed collar on the tree trunk, so that the two fixing plates 602 located inside the collar are in contact with the outer wall of the tree trunk, thus playing a role in limiting and fixing the collar, and further facilitating the fixing of the measuring cylinder 7 on the outer wall of the tree trunk.

[0055] It further includes a second spring 603. One end of the second spring 603 is fixedly connected to the inner side wall of the arc-shaped plate 6, and the other end is fixedly connected to the outer side wall of the fixing plate 602. A guide rod 604 is fixedly connected to the fixing plate 602, and a limiting block 605 is fixedly connected to one end of the guide rod 604 passing through the arc-shaped plate 6.

[0056] Since the fixing plate 602 is slidably arranged on the arc-shaped plate 6 through the guide rod 604 and the second spring 603 has elastic contraction force, the fixing plate 602 can slide within the collar. Therefore, when the collar is sleeved on the outer wall of the tree trunk, while playing a fixing effect on the measuring cylinder 7, it does not affect the growth of the sapling.

[0057] It should be noted that when the fixing plate 602 moves within the collar, the guide rod 604 moves synchronously with the fixing plate 602 on the arc-shaped plate 6, so as to play a role in limiting and guiding the fixing plate 602, and further ensure the stability of the fixing plate 602 moving within the collar, and improve the stability of the collar sleeved on the tree trunk;

[0058] The conduit 804 is a stretchable and contractible hose, so the conduit 804 will not interfere with the snap connection or disassembly of the collar.

[0059] Example 4: Refer to Figure 1 、 Figure 7, A device for measuring the root depth of a tree, which is basically the same as that in Embodiment 1. Further, the straightening component includes a sleeve 5 fixedly connected to the outer walls around the observation cylinder 1. A sliding disk 502 is slidably connected inside the sleeve 5. A support rod 503 is fixedly connected to the sliding disk 502. One end of the support rod 503 away from the sliding disk 502 is fixedly connected with an arc-shaped block 504. A first spring 501 is fixedly connected between the sliding disk 502 and the inner wall of the sleeve 5.

[0060] During the period when the sapling is planted in the upper measuring cavity 101, the sliding disk 502 is pushed by the first spring 501 to push the support rod 503 to drive the arc-shaped block 504 to move towards the outer wall close to the outer wall of the tree trunk and fit with the outer wall of the tree trunk (it should be noted that since the four arc-shaped blocks 504 are equidistantly distributed around the outer wall of the tree trunk), so as to achieve the effect of clamping and fixing the sapling while also being able to straighten the sapling, preventing the sapling from tilting or falling during cultivation. At the same time, since the arc-shaped block 504 is movably arranged by sliding the sliding disk 502 in the sleeve 5 and the first spring 501 has elastic contraction force, it does not affect the growth of the sapling while straightening the sapling.

[0061] Embodiment 5: Refer to Figure 8 , A device for measuring the root depth of a tree, which is basically the same as that in Embodiment 1. Further, it also includes a sealing sleeve 301 sleeved on the outer wall of the connecting shaft 203. The sealing sleeve 301 is fixedly connected to the inner wall of the sliding box 2. A sealing ring 302 is arranged on the sealing sleeve 301. The sealing ring 302 fits with the outer wall of the connecting shaft 203; by the sealing ring 302 fitting with the outer wall of the connecting shaft 203, the sealing performance of the sliding box 2 is increased, preventing the water stored inside the sliding box 2 from leaking through the gap at the connection between the threaded part 3 and the sliding box 2.

[0062] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
