Description

Technical Field

[0001] The invention relates to the technical field of tree root samplers, and in particular to a tree diseased part sampler for forestry monitoring. Background Art

[0002] The roots of trees can indeed develop diseases, and root diseases can seriously affect the health and growth of trees. Common root diseases include root rot, root knot nematode disease, root white rot, root atrophy, etc. Common symptoms of root diseases include root discoloration, such as blackening, browning or whitening; root rot, where the roots appear to rot or soften; abnormal tree growth, such as slow growth, yellowing or wilting leaves; leaf diseases, where root problems often cause leaf lesions, such as yellowing and falling. The keys to preventing root diseases include choosing disease-resistant varieties, maintaining good soil management and drainage conditions, and regularly inspecting and maintaining tree health.

[0003] The sampling method is often used to inspect the roots of trees, that is, to intercept root samples in the soil (including the roots and the soil near the roots) and analyze them to obtain the disease conditions of the tree roots. When sampling the roots of trees, the existing samplers for tree inspection need to be inserted into the soil, which will cause the roots and soil to loosen when the roots are cut, resulting in confusion between the roots and the soil, thereby affecting the length of the intercepted roots and their distribution in the soil. In addition, due to different soil moisture, the soil will become loose or lost when the sample is taken out, thereby reducing the authenticity of the sample.

[0052] Further, see Figure 5 , Figure 5 for Figure 4 Enlarged view of point A in the middle. The tree disease part sampler 100 of the present invention also includes an elastic shrink plate 154, which is arranged at the bottom of the outer ring tube 153 and the inner ring tube 143. The elastic shrink plate 154 is arranged to cover the bottom openings of the outer ring tube 153 and the inner ring tube 143 when the tree disease part sampler 100 is inserted into the sampling position, and when the outer ring second driving member pushes the outer ring hinge rod 220 and the inner ring second driving member pushes the inner ring hinge rod 210, the elastic shrink plate 154 can be pushed open by the outer ring hinge rod 220 and the inner ring hinge rod 210, so that the outer ring hinge rod 220 and the inner ring hinge rod 210 extend underground. The provision of the elastic shrink plate 154 can effectively prevent the soil from entering the interior of the outer ring tube 153 and the inner ring tube 143 when the outer ring tube 153 and the inner ring tube 143 contact the soil.

[0053] Further, see Figure 1 The tree diseased part sampler 100 of the present invention further includes a hammering device 111 and a handle 112. The handle 112 facilitates the technician to use the tree diseased part sampler 100; the hammering device 111 is used to assist the tree diseased part sampler 100 to extend into the soil, saving manpower.

[0054] The sampling process of the tree disease part sampler 100 of the present invention is as follows:

[0055] Before work begins:

[0056] The first outer ring telescopic rod group 132 and the first inner ring telescopic rod group 122 are retracted to the limit state; the second outer ring telescopic rod group 151 and the second inner ring telescopic rod group 141 are extended to the limit state, both of which are hydraulically pushed and cannot be extended or retracted.

[0057] After work starts:

[0058] Step 1: The technician holds the handle 112 and places the tree disease sampler 100 at the sampling position. The inner tube ring mechanism 140 and the outer tube ring mechanism 150 contact the soil. At this time, the elastic contraction plate 154 is in a closed state to prevent the soil from entering the inner ring tube 143 and the outer ring tube 153. The hammer device 111 is turned on and the entire device is hammered through the connecting base 113. The outer ring tube 153 and the inner ring tube 143 are inserted into the soil by half (this is only an exemplary description, and the actual insertion depth of the soil can be determined according to the state of the soil and the sampling requirements). At this time, the soil insertion is completed;

[0059] Before step 2 starts: the outer push rod group 133 and the inner push rod group 123 are located inside the inner ring tube 143 and the outer ring tube 153, and the bottom ends of the inner ring hinge rod 210 and the outer ring hinge rod 220 are on the inner surface of the elastic contraction plate 154, that is, at the bottom end of the outer ring tube 153;

[0060] Step 2: The second outer ring telescopic rod group 151 and the second inner ring telescopic rod group 141 are contracted, so that the inner tube ring connecting plate 142 and the outer tube ring connecting plate 152 move upward, driving the inner ring tube 143 and the outer ring tube 153 to move upward, and the upward movement of the inner ring tube 143 and the outer ring tube 153 causes the inner ring hinge rod 210 and the outer ring hinge rod 220 to push out the elastic contraction plate 154 (154 is opened), and then stop contracting;

[0061] Step 3: The first outer ring telescopic rod group 132 and the first inner ring telescopic rod group 122 begin to press downward to fold the bottom ends of the inner ring hinged rod 210 and the outer ring hinged rod 220. When the folding reaches the folding limit or the bottom ends cannot be pressed due to being pressed to the bottom, the first pressure sensor 121 and the second pressure sensor 131 will feel the increase of force; then the first pressure sensor 121 and the second pressure sensor 131 send out signals to retract the second outer ring telescopic rod group 151 and the second inner ring telescopic rod group 141 again (and at the same time stop the downward pressure of the outer push rod group 133 and the inner push rod group 123), and move the inner ring tube 143 and the outer ring tube 153 upward again to further extend the inner ring hinged rod 210 and the outer ring hinged rod 220, and then stop retracting;

[0062] Step 4: The first outer ring telescopic rod group 132 and the first inner ring telescopic rod group 122 start to press down to fold the inner ring hinge rod 210 and the outer ring hinge rod 220, and repeat this process until the inner ring tube 143 and the outer ring tube 153 are completely pulled out of the soil, and the inner ring hinge rod 210 and the outer ring hinge rod 220 are completely folded inside the soil;

[0063] Step 5: At this time, the sampling outer cylinder 115 descends, and the cutting member at the bottom of the sampling outer cylinder 115 cuts off the tree roots, and the sampling outer cylinder 115 collects enough soil, and then the forest disease part sampler 100 is pulled out as a whole to complete the sampling;

[0064] Step 6: Loosen the bolts 213 or the consumable parts to straighten the inner ring hinge rod 210 and the outer ring hinge rod 220 for next use.

[0065] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
