Therefore, the practicality of the existing sampling device is low. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.
[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.
[0028] In the following embodiments and drawings, reference is made to Figures 1 to 3 The coordinate system is such that the direction indicated by the arrow of the X-axis is right, the direction indicated by the arrow of the Y-axis is forward, and the direction indicated by the arrow of the Z-axis is upward. It can be understood that the surface of the shovel body 100 that contacts and holds the soil is set as the inner surface, and the other opposite surface is set as the outer surface.
[0029] Embodiment 1:
[0030] like Figure 1 and Figure 2 As shown, in this embodiment, a wild rice rhizosphere microorganism sampling device is provided, including: a shovel body 100 and a rod body 200; the rod body 200 is connected to the shovel body 100, the shovel body 100 includes a main body 110 and a water control part 120, a plurality of water control holes 121 are opened on the surface of the water control part 120, and the cross-sectional area of the inner end of the water control hole 121 is larger than the cross-sectional area of the outer end, a side wall of the water control hole 121 is set as an inclined surface 1211, and a side wall arranged opposite to a side wall of the water control hole 121 is set as an arc surface 1212, and the protruding direction of the arc surface 1212 is set toward the inclined surface 1211.
[0031] Specifically, the rod body 200 may be selected but not limited to a cylindrical rod body 200, the cross-sectional shape of the shovel body 100 may be selected but not limited to an arc shape, and the rod body 200 and the shovel body 100 may be connected by threads or glue. The left and right ends of the main body 110 are both provided with water control parts 120, that is, the number of water control parts 120 is set to two, so that researchers can choose the left end or the right end to control water, thereby increasing the practicality of the device. A plurality of water control holes 121 are arranged in a matrix on the water control part 120, and the cross-sectional area of the inner end of the water control hole 121 is larger than the cross-sectional area of the outer end. One side wall of the water control hole 121 is set as an inclined surface 1211, and the other side wall is set as an arc surface 1212, and the two side walls are connected by a straight surface, and the arc surface 1212 is set close to the inclined surface 1211. In this way, the shape of the water control hole 121 is similar to the opening shape of the shredder, so that the amount of soil that can pass through is smaller. The material of the shovel body 100 can be set to plastic. In this case, the water control hole 121 can be formed by hot-melt molding of a mold of a corresponding shape.
[0032] It is worth noting that, by connecting a water control part 120 with a plurality of water control holes 121 to the main body 110, and the cross-sectional area of the inner end of each water control part 120 is larger than the cross-sectional area of the outer end, it is possible to ensure that water flows out of the water control hole 121, and prevent excessive soil loss through the hole design of wide inside and narrow outside, and the contact area between the water control part 120 and the soil is increased by the coordinated arrangement of the inclined surface 1211 and the arc surface 1212, so that the soil can be fixed to a certain extent to further prevent soil loss; and only a slight tilt of the rod body 200 is required to drive the shovel body 100 to tilt, and the water in the soil can flow out from each water control hole 121 under the action of gravity, and the water control operation is simpler, which can be completed by one person, and the water filtering speed is faster, and it can also avoid staining the hands. Therefore, the device of the present application is more practical.
[0033] In order to reduce the loss of soil, Figure 1 and Figure 2 As shown, in some embodiments, the inclined surface 1211 is gradually inclined from the inner end to the outer end toward the direction close to the rod body 200.
[0034] Specifically, the bottom side wall of the water control hole 121 is set as a slope 1211, and the top side wall is set as an arc surface 1212. In this way, after excavation is completed, the soil moves downward under the action of gravity and is supported by the bottom slope 1211 of the water control hole 121, and the water needs to flow upward from the bottom of the water control hole 121 along the slope 1211. The two movement directions are different, so that soil loss can be further avoided.
[0035] In another embodiment, the inclined surface 1211 is gradually inclined from the inner end to the outer end toward a direction away from the rod body 200 .
[0036] Specifically, the top side wall of the water control hole 121 is set as an inclined surface 1211, and the bottom side wall is set as an arc surface 1212. At this time, water can flow downward more easily along the direction of the inclined surface 1211, which is convenient for rapid water control.
[0037] In order to increase the practicality of the device, Figure 1 As shown, in some embodiments, the angle between the plane formed by the two ends of the main body 110 and the plane where the water control portion 120 is located is equal to or less than 90°.
[0038] Specifically, the left and right ends of the main body 110 form a horizontal plane, and the water control part 120 is set as a plate body perpendicular to the horizontal plane. In this way, the two water control parts 120 are respectively installed vertically at the left and right ends of the main body 110, so as to facilitate the soil in the main body 110 to be limited, so as to prevent the soil from falling from the left and right ends of the main body 110. And it can be understood that the angle between the plane formed by the two ends of the main body 110 and the plane where the water control part 120 is located is set according to actual production requirements, and is not limited here. It is only necessary to ensure that the moisture in the soil can leak from the water control part 120. For example, the angle between the plane formed by the two ends of the main body 110 and the plane where the water control part 120 is located is greater than 90°, and the water control part 120 can form an integral arc surface with the main body 110, so as to facilitate the digging of soil.
[0039] To facilitate soil excavation, Figure 1 and Figure 3 As shown, in some embodiments, a plug-in portion 130 is provided at one end of the shovel body 100 away from the rod body 200 .
[0040] Specifically, the bottom ends of the main body 110 and the water control part 120 are provided with a plug-in part 130, and the plug-in part 130 can be set as an arc surface. By providing the plug-in part 130, it is convenient for the device to be inserted into the rice field to dig the soil. Among them, the specific layout of the plug-in part 130 is not limited here, and it is only necessary to ensure that the shovel body 100 can be inserted into the rice field. For example, the plug-in part 130 can also be set as a conical surface. For another example, the plug-in part 130 can be set as a plurality of plug-in strips, and an inverted V-shaped groove is provided on the end of the plug-in strip away from the rod body 200. In this way, while facilitating the insertion of the shovel body 100 into the rice field, it prevents the plug-in strip from damaging the root system of the rice, and also reduces the material cost to a certain extent.
[0041] Example 2
[0042] This embodiment is similar to the first embodiment, except that the water control portion 120 can form an integral arc surface with the main body 110 , and the water control portion 120 is disposed in the middle of the shovel body 100 .
[0043] Specifically, both left and right ends of the water control part 120 are connected to the main body 110, and the main body 110 is arranged higher than the water control part 120 in the Y-axis direction, that is, the water control part 120 is at the bottom. In this way, after taking out the soil, there is no need to place the shovel body 100 on the side, and the water will flow out from the water control hole 121 on the water control part 120 under the action of gravity, making the water control operation easier.
[0044] Example 3
[0045] It is understandable that in the research process, different paddy field soils need to be sampled. The water in wild paddy fields is deeper, while the water in cultivated paddy fields is shallower. However, the fixed handle of the existing sampling device cannot adapt well to different paddy field depths. In order to avoid this problem, based on Example 1 or 2, as shown in Figure 1 and Figure 3 As shown, in this embodiment, the rod body 200 is connected to the telescopic member 300 .
[0046] Specifically, the top of the rod body 200 is connected with a telescopic member 300, and the telescopic member 300 can be provided so that the whole device can be extended when sampling a paddy field with deeper water, and can be shortened when sampling a paddy field with shallower water, thereby effectively increasing the practicability of the device.
[0047] In order to facilitate the use of the telescopic member 300, as Figure 1 and Figure 3 As shown, in some embodiments, the telescopic member 300 includes a telescopic sleeve, the rod body 200 is slidably disposed in the telescopic sleeve, and an end of the rod body 200 away from the shovel body 100 is limitedly connected to an end of the telescopic sleeve close to the shovel body 100.
[0048] Specifically, the telescopic sleeve is arranged in cooperation with the rod body 200 for telescoping. In a static state, the telescopic sleeve and the rod body 200 are tightly connected by friction. The rod body 200 can slide in the telescopic sleeve only under the action of a certain external force. A locking protrusion is provided at the top of the rod body 200, and a locking groove is provided at the bottom of the telescopic sleeve, so that the two are limitedly connected to prevent the top of the rod body 200 from sliding off the bottom of the telescopic sleeve.
[0049] Example 4
[0050] This embodiment is a further implementation of embodiment 1, 2 or 3. Figure 1 and Figure 3 As shown, in this embodiment, a covering cover 140 is disposed at one end of the shovel body 100 close to the rod body 200 .
[0051] Specifically, a covering cover 140 is provided at the top of the shovel body 100, and the covering cover 140 is connected to the bottom end of the rod body 200. The cross-sectional area of the covering cover 140 is larger than the cross-sectional area of the shovel body 100, that is, the covering cover 140 is provided on the main body 110 and the water control part 120, so that the soil on the main body 110 can be limited by the covering cover 140, thereby preventing the soil from leaking out from the top of the main body 110.
[0052] To prevent the soil from leaking out easily, Figure 1 and Figure 3 As shown, in some embodiments, an anti-skid layer 111 is provided at one end of the shovel body 100 away from the rod body 200 .
[0053] Specifically, an anti-skid layer 111 is provided at the bottom of the main body 110 . The anti-skid layer 111 may be, but is not limited to, an anti-skid strip made of plastic material. The anti-skid strip can prevent soil from easily leaking out of the bottom of the shovel body 100 .
[0054] In order to facilitate the shovel body 100 to scoop up a corresponding volume of soil, in some embodiments, the length of the shovel body 100 is set to 25 cm to 40 cm.
[0055] Specifically, since the depth of rhizosphere soil is generally 20 cm to 30 cm, and when sampling the rhizosphere soil of wild rice, only about 100 g of sample is needed, therefore, the device sets the length of the shovel body 100 to 25 cm to 40 cm, which can effectively avoid over- or under-sampling caused by the volume of the shovel body 100 deviating from actual needs, and at the same time, effectively reduce production costs. It can be understood that the lengths of the main body 110 and the water control part 120 are equal, and the lengths of the two are preferably 25 cm, 30 cm or 35 cm.
[0056] In order to facilitate gripping the rod body 200, Figure 1 and Figure 3 As shown, in some embodiments, the rod body 200 is connected to a gripping portion 210 .
[0057] Specifically, the gripping portion 210 may be, but is not limited to, a ring-shaped handle, and the gripping portion 210 is used to facilitate soil removal.
[0058] In order to increase the practicality of the device, in some embodiments, an anti-slip cover is provided on the gripping portion 210 .
[0059] Specifically, the anti-slip cover may be, but is not limited to, a rubber layer, and a plurality of protrusions are evenly arranged on the rubber layer, so that the friction between the human hand and the gripping portion 210 is greater, making it easier to grip.
