Description

Technical Field

[0001] The utility model relates to the technical field of crop sampling equipment, in particular to a handheld convenient sampling device for field crop leaves. Background Art

[0002] Sampling and analyzing field crop leaves is a fundamental and critical task in agricultural research, crop breeding, and plant protection. By examining leaf samples, we can obtain important information such as crop nutritional status, pest and disease infestation, and gene expression patterns, providing a scientific basis for crop growth regulation, pest and disease control, and the selection of superior varieties.

[0003] Currently, the sampling of crop leaves in the field is mostly done manually. Operators typically use tools such as scissors and blades to cut or snip the target leaves from the plant and then place the leaves into containers such as collection bags and boxes. However, this traditional sampling method has many shortcomings: First, the sampling process requires manual handheld tools for cutting and collecting, which is cumbersome and inefficient, especially when sampling large fields. The labor intensity is high; second, manually cut leaves often contain excess petioles, residual branches, or non-target mesophyll parts, requiring additional pruning to meet the requirements of experimental analysis (such as leaf grinding and component extraction), increasing the workload and time cost of sample processing; in addition, the standardization of manual operation is difficult to ensure, and the cutting force and angle of different operators vary, which may lead to inconsistent size and morphology of the obtained leaf samples, affecting the accuracy and repeatability of subsequent experimental results.

[0004] The leaf sampling devices in the existing technology are mostly complex in structure and large in size, which are not convenient for handheld operation in the field. It is also difficult to achieve the integration of rapid clamping, precise cutting and direct collection of leaves. It still cannot effectively solve the problems of low efficiency and cumbersome subsequent processing in traditional manual sampling.

[0005] In view of this, the present invention is proposed to solve the above technical problems. Utility Model Content

[0009] The sampling part includes a shearing blade and a matching knife cylinder, the shearing blade and the matching knife cylinder are respectively fixedly arranged on the inner sides of the two mounting parts, the first through hole is coaxially arranged with the shearing blade, and the second through hole is coaxially arranged with the matching knife cylinder;

[0010] A collecting pipe, wherein the collecting pipe portion is detachably arranged at the second through hole;

[0011] The inner diameter of the first through hole is smaller than the inner diameter of the shear blade. A slidable push block is provided in the shear blade. A connecting rod is provided at one end of the push block close to the first through hole. The connecting rod passes through the first through hole, and a button is fixed to the protruding end of the connecting rod. A spring is directly provided at the bottom of the button and the first through hole, and the spring is sleeved on the connecting rod.

[0012] Furthermore, the shearing blade is an annular blade, and the outer diameter of the shearing blade is smaller than the inner diameter of the matching knife cylinder. When the shearing blade extends into the matching knife cylinder to complete shearing, the outer wall of the shearing blade fits with the inner wall of the matching knife cylinder.

DETAILED DESCRIPTION

[0027] The specific implementation of the present utility model is further described in detail with reference to the accompanying drawings.

[0028] See also Figures 1 to 3As shown, an embodiment of the present application provides a handheld convenient sampling device for field crop leaves, including a handheld portion, a sampling portion and a collecting tube 4. The handheld portion includes a first handheld arm 1 and a second handheld arm 2. The first handheld arm 1 and the second handheld arm 2 are arranged in a close fit with each other up and down, and the middle part is hinged by a hinge shaft 3. The first handheld arm 1 and the second handheld arm 2 have handheld holes at the lower part, and are both provided with mounting portions 5 at the upper part. The two mounting portions 5 are symmetrically arranged, and the two mounting portions 5 are respectively provided with a first through hole and a second through hole. The sampling portion includes a shearing blade 8 and a matching knife cylinder 12. The shearing blade 8 and the matching knife cylinder 12 are respectively fixedly arranged on the inner sides of the two mounting portions 5. The first through hole is coaxially arranged with the shearing blade 8, and the second through hole is coaxially arranged with the matching knife cylinder 12. The collecting tube 4 is partially detachably arranged at the second through hole, and the inner diameter of the collecting tube 4 is not less than the inner diameter of the matching knife cylinder 12. Inch, the inner diameter of the first through hole is smaller than the inner diameter of the shear blade 8, and a slidable ejection block 9 is provided in the shear blade 8, and a connecting rod is provided at one end of the ejection block 9 near the first through hole. The connecting rod passes through the first through hole, and a button 10 is fixed to the protruding end of the connecting rod. A spring 11 is directly provided at the bottom of the button 10 and the first through hole, and the spring 11 is sleeved on the connecting rod. Since the shear blade 8 is a cylindrical structure, when shearing blades, occasionally a blade will be stuck in the shear blade 8 or the matching knife cylinder 12. At this time, pressing the button 10, the spring 11 is compressed, so that the button 10 drives the ejection block 9 to slide downward through the connecting rod, and the ejection block 9 slides downward to push the shear blade 8 or the blade in the matching knife cylinder 12 into the collecting tube 4, and then release the button 10, the spring 11 resets, and drives the ejection block 9 to slide upward through the connecting rod, so that the ejection block 9 is reset.

[0029] In the above scheme, a shearing blade 8 and a matching knife cylinder 12 are respectively arranged between the inner sides of the hinged first hand-held arm 1 and the second hand-held arm 2. When the lower ends of the first hand-held arm 1 and the second hand-held arm 2 are squeezed against each other, the two mounting parts 5 approach each other, thereby driving the shearing blade 8 and the matching knife cylinder 12 to approach each other, so that the shearing blade 8 extends into the matching knife cylinder 12 to shear the leaves, and the sheared leaves are collected through the provided collection tube 4, thereby reducing the operating steps of shearing and collecting leaves, reducing labor intensity, and the sheared leaves are of the same size, which is convenient for different operators to operate, and will not bring in extra petioles and branches, reducing the workload of subsequent leaf processing, thereby improving the accuracy of subsequent experimental results, and can achieve rapid clamping, precise shearing and simultaneous collection of leaves.

[0030] In some possible implementations, see Figures 1 to 3 As shown, the shear blade 8 is an annular blade, and the outer diameter of the shear blade 8 is smaller than the inner diameter of the matching knife cylinder 12. When the shear blade 8 extends into the matching knife cylinder 12 to complete the shearing, the outer wall of the shear blade 8 fits with the inner wall of the matching knife cylinder 12 to shear and cut the blade.

[0031] In some possible implementations, see Figure 1 As shown, the collecting tube 4 is a transparent plastic tube, which is convenient for observing the condition of the sheared blades in the collecting tube 4. The number of blades can be directly observed through the collecting tube 4, so as to replace the collecting tube 4 or take out the blades in the collecting tube 4.

[0032] In some possible implementations, see Figure 1 and Figure 2 As shown, a threaded hole is provided on one side of the mounting portion 5 connected to the first hand-held arm 1, and the threaded hole is connected to the second through hole. A threaded screw 7 is provided in the threaded hole, and a nut is provided on the screw 7. The screw 7 is detachably connected to the collecting tube 4.

[0033] In the above scheme, when fixing the collecting tube 4, the open end of the collecting tube 4 is inserted into the bottom of the mounting portion 5 connected to the first hand-held arm 1, so that the open end of the collecting tube 4 abuts against the bottom of the mating knife cylinder 12, and then the screw 7 is rotated so that the screw 7 is screwed into the threaded hole and abuts against the outer wall of the collecting tube 4, thereby completing the fixation of the collecting tube 4.

[0034] In some possible implementation schemes, a return spring is provided between the lower part of the first hand-held arm 1 and the second hand-held arm 2. After the blade shearing is completed once, it is only necessary to release the squeezing force of the hand on the first hand-held arm 1 and the second hand-held arm 2. Under the action of the return spring force, the first hand-held arm 1 and the second hand-held arm 2 rotate toward each other along the hinge axis 3, reducing the operating intensity and strength of the operator's hand, and further reducing the wear on the operator's hand.

[0035] In some possible implementation schemes, a storage hook and a matching storage ring are respectively provided on the inner sides of the bottom of the first handheld arm 1 and the second handheld arm 2, and the storage hook is hung with the storage ring.

[0036] After completing the shearing of the blades, the hanging ring is hung on the storage hook so that the hanging ring and the storage hook fix the position of the shear blade 8 and the matching knife cylinder 12, avoiding accidental touch by the operator and causing cuts, reducing the volume and facilitating storage.

[0037] In some possible implementations, see Figure 2 As shown, a rubber fixing ring 6 is provided at the bottom of the mounting portion 5 on the first hand-held arm 1, and the inner wall of the rubber fixing ring 6 is detachably connected to the outer wall of the collecting tube 4, thereby increasing the friction between the collecting tube 4 and the second through hole and further strengthening the fixing strength of the collecting tube 4.

[0038] This specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of protection of the utility model, they are protected by patent law.
